Company lines, hospitals, care units, etc., may have many departments, often distributed in a large area, for the contact of the moving people, it is still more convenient to use mobile phone calls, the use of mobile phones is still very high, and still need Carrying a mobile phone with you, for women, there are often cases where the mobile phone is not received by the leather bag, and there is also a situation where the mobile phone has no power.

In addition, in a hospital ward, the patient may leave the hospital bed, so that the medical staff can not find the patient, or the medical staff can patrol the room everywhere, or when the patient is in an emergency, it is not easy to quickly find the medical staff. To this end, in order to achieve an effective link and call, a more effective way is to use WIFI free mobile phone, as long as the patient carries a mobile phone with him. For this reason, if the wristband router of the present invention is used, everyone can connect anytime, anywhere. You can know the location of the caller and the receiver, can record, can analyze, can handle, can be accurately positioned, and do not miss any doubts about a phone call. For the management of unit personnel attendance, it can produce many functions.

For the safety of the solitary people and the remote care of the living, it is often not easy to use because of the complicated installation of the network and the inhumanity of the use, especially for the elderly and the weak, so it cannot be effectively popularized, for example, using ZIGBEE, etc. The technology of the related wireless sensor network; in addition, the wearable sensor and the environmental sensor are of great importance to the health of the solitary person, but the current product and technology for the solitary person or remotely For the caregivers, there is no very friendly way of using them.

The object of the present invention is to provide a smart networked system, in particular, a smart networked system based on a light source. The light source is an LED electric light with built-in Bluetooth 4.0 or higher communication function, and indoor personnel wear at least Bluetooth 4.0 or above communication and WIFI.

The object of the present invention is to provide a smart networking system, which is a smart network based on a light source. The light source is an LED light with built-in Bluetooth 4.0 or higher communication function, and indoor personnel wear at least Bluetooth communication and WIFI communication functions. Routers, such as headphones or bracelets, etc., the router here has the function of identification card; it is more effective and accurate for the management and positioning of unit personnel attendance.

The object of the present invention is to provide a smart networking system, which is a smart network based on a light source. The light source is an LED light with built-in Bluetooth 4.0 or higher communication function, and indoor personnel wear at least Bluetooth communication and WIFI communication functions. A router, such as a headset or a wristband, has a function of identifying a card; the router reads the sensor data worn by the user through Bluetooth communication, and even installs environmental sensor data on the LED light. In conjunction with the above positioning data, a smart networked sensor system is constructed.

With the implementation of the present invention, at least the following advancements can be achieved:

1. By replacing the LED light with built-in Bluetooth 4.0 communication function, it is not necessary to change the lamp holder, and there is no need to re-route the network. The smart network is naturally built, so many home automation visions are completed. For home care can play a big role, so that the solitary or the elderly can wear a physiological signal sensor, plus a collar router or ear-hook voice router or a bracelet talk router, the location and its physiology After the information is collected, it will be sent to the cloud. When the old man falls, the signal change generated by the physiological signal sensor can also send a help signal due to system monitoring. At the same time, the elderly can directly call the help signal through the voice router.

2. Each LED light source can assist in the triangulation of its Bluetooth node, so that people or things equipped with the Bluetooth node can be tracked to provide effective assistance.

3. Each LED light source can assist in triangulating the Bluetooth node under its control, so that the person or animal equipped with the Bluetooth node can be tracked to provide effective illumination, that is, the LED light source closest to the person or animal. Lighting will be provided, and the LED light source away from people or animals will be automatically extinguished to achieve energy saving and carbon reduction.

4. Each LED light source can be tinted or dimmed through a router with Bluetooth 4.0 or higher communication and WIFI communication functions such as a mobile phone or other mobile device.

For LED lights that are converted into built-in Bluetooth 4.0 communication functions, please refer to the invention patent filed by the inventor, Case No. 100127360 "Light source-based Internet of Things". The invention proposes a circuit module with a communication function of Bluetooth 4.0 or above built in an existing standard LED bulb or LED tube, so that the user can directly replace the old electric lamp or the lamp tube to become an LED electric lamp with communication function.

The positioning function referred to in the present invention mainly uses the replacement of the original electric lamp (light bulb or lamp tube) to become a LED electric lamp with communication function, and the LED electric lamp has a circuit module with a communication function of Bluetooth 4.0 or higher; another router is provided, at least With Bluetooth 4.0 or above communication and WIFI communication function, the user scans the Bluetooth identification code (BTID) and the Received Signal-Strength Indicator (RSSI) value of the LED light lamp near the location where the user is located, and Send the data to a nearby gateway or cloud via WIFI, and then the cloud will send the calculated positioning information or knowledge to the user router via WIFI or send it to the relevant care or monitoring personnel. . The acquisition of the positioning information or knowledge is based on the technology of three-point positioning. The main method is the triangular positioning technology and the power transmission control technology to effectively improve the positioning accuracy. The execution sequence is as follows: Step 1: The Bluetooth master node uses the scanning function to read In the reach of the Bluetooth 4.0 reachable range, the Bluetooth master node's transmit and receive power is the maximum level, and the scan time is very short, as little as 1/20 second; Step 2, use at least one The tri-light source combination performs triangulation to determine the possible position of the Bluetooth master node in the scanning range. Whether it is in the set room, multiple three-light source combinations can be used to improve the positioning accuracy; Step 3: Downgrade the Bluetooth main node's transmission Power, so that the range of scanning can be reduced, for example, two meters radius; basically, if the received signal strength indicator (RSSI) can be accurate, there is no need to change the transmission power, it can be said that it is the easiest positioning method, but the RSSI is generally accurate. Degree, the specification of Bluetooth 4.0 is +-6dB, therefore, the master node can gradually reduce its transmit power, as shown in Table 1. To narrow the coverage range, And with FIGS. 1 and 2 with description, to improve the positioning accuracy. Step 4, again using the triangle positioning to improve its positioning accuracy.

Figure 1 shows the basic Bluetooth triangulation method. The thick solid line represents the range covered by the maximum power, the thin dotted line represents the range covered by half of the power, and the character 93 and the character 91 appear in the ABC three-circle intersection during the maximum power scan; 92 appears in the BC two-circle intersection, but not in the ABC three-circle intersection; when using half-power scanning, the characters 93 appear in the abc three small circle intersection, the positioning accuracy is higher; and the character 91 belongs to a and A ∩B∩C does not belong to b or c, and the positioning accuracy is also higher; the character 92 belongs to b∩c but does not belong to A, and the positioning accuracy is also higher. It can be understood that if the 1/4 power scan is performed, higher positioning accuracy can be obtained.

In addition, if the RSSI is further used to estimate the distance of the person, as shown in FIG. 2, the position of the character 96 can be estimated by the RSSI value obtained from the three points of the ABC. The ABC three points can be three different positions of LED light sources, and each of the light source built-in Bluetooth 4.0 slave node modules can be used as a reference node for indoor positioning, and the character 96 is equipped with the router referred to in the present invention, so It scans for the ABC three-point individual Bluetooth identification code (BTID) and its RSSI value.

Since the ceiling-mounted luminaire has a high-powered right, the router of the present invention can effectively perform a line of sight (LOS) channel between the slave node and the master node without serious multi-path transmission, so Accuracy can be greatly improved. Appropriate corrections can be made according to the number of mobile characters, or fuzzy inferences, or neural inferences can be used to build models.

For example, the source of the illumination is mostly about two to four meters from the ground, and the size of the room is about three to five meters long; the living room may be four to ten meters; if using multiple power sweeps as described above, for example, Figure 1 The full power, half power, and 1/4 power shown can effectively limit the positioning accuracy to the accuracy of the room, for example, 0.5-1 meters.

In order to improve the positioning accuracy, various correction techniques can also be utilized. For example, because the position of the indoor electric lamp is fixed for a long time, and the flow of indoor personnel or pets does not change much, especially when the elderly live alone, it is basically visible that there is no movement of the person. The multi-path change of the Bluetooth communication is caused, so the user can walk around the room and wear a mobile phone (note: the mobile phone is an embodiment of the router referred to in the present invention) to read its location at any time, and compare the actual situation. Position, enter the error into the phone to complete the calibration process.

In addition, you can also use indoor Bluetooth 4.0 electrical devices, such as air conditioners, TVs, refrigerators, computers, dehumidifiers, etc., because their location is known, you can first enter their corresponding Bluetooth identification code (BTID) and Its three-dimensional coordinates in space provide a reference point for the Bluetooth slave node provided in addition to the LED light source.

The invention utilizes the LED light source as the intelligent networking, and the user only needs to replace the electric light with the LED light source of the invention, and after the following APP program, it can be plug and play:

1. Draw an indoor compartment map on the grid paper of the mobile phone program and mark the position of the main light with BT4+WIFI. Upload the cloud.

2. Mark the fixed position of the indoor Bluetooth electrical device. Upload the cloud.

3. The user wears a Bluetooth bracelet and moves to the predetermined position according to the instructions of the mobile phone. Upload the cloud.

4. The cloud correction program establishes the indoor RSSI intensity map of each main lamp.

The indoor compartment map is further described as follows. The drawing of the indoor map and the location of the marked electric light can be turned into an APP for the user to download and input by himself, as shown in FIG. 3, which is an indoor building LED light source of the present invention. 3D coordinates and space name setting diagram. First, a piece of paper appears on the screen, each square represents 0.5 meters square. The user sets the north to the Y axis according to the checkered paper, and the east is the X axis. Based on the interior layout configuration, the LED is used. The location of the light source (also Bluetooth 4.0 slave) is marked, for example, 81 (restaurant light), 82 (living room light), 83 (kitchen light), 84 (main bedroom light), 85 (bathroom light), 86 (room one) The lights), 87 (room lights), and 88 (walking lights) also indicate the height of the Z axis, which helps the three-point positioning operation.

The kitchen, bathroom, living room, room, balcony, dining room, and bedroom should be clearly marked, especially the location of the bed (not shown), which helps to determine if the user is sleeping or falling to the ground.

The position of the door should also be marked. This will help to determine the triangle positioning. It must also determine whether the door is closed or not, and the door may be closed to indicate some privacy conditions. For example, if you enter the bathroom or toilet, you should close the door. If you do not close the door, you may wash your face.

Colors can be used to represent the location of the kitchen, bathroom, living room, room, balcony, dining room, door, and electrical appliances.

After installation, each communication power level should establish its communication model, as shown in Figure 4. The method of estimating the spatial position by scanning the RSSI value obtained by the reference node can be referred to "Enhanced RSSI-Based Real-Time User Location Tracking System for Indoor and Outdoor Environments," Erin-Ee-Lin Lau and Wan-Young Chung, Dongseo University, Korea, 2007 International Conference on Convergence Information Technology, IEEE. This is a technique that is familiar to those skilled in the art and will not be described again here.

The family (on the same floor, different floors), the company (school, hospital, government department), the factory (large factory building in the production department), if the use area is wide, it is difficult to accurately locate, the invention can greatly reduce the wiring cost. The reasons are as follows:

Referring to FIG. 5, an embodiment of a preferred LED light source configuration of the present invention is preferred. Each LED light source is preferably a Bluetooth 4.0 slave node, such as a built-in TI CC2540 chip module, and is used under the light source. A router with a Bluetooth dual mode node and WIFI. Its operation mode: the staff equipped router has its Bluetooth master node regularly scans the Bluetooth slave nodes in the area under its communication jurisdiction, scans the obtained Bluetooth slave node data, and collects it and then continuously sends it to the Internet through the router's WIFI. Or the cloud, the positioning operation of the user.

Basically, each Bluetooth communication node has a unique Bluetooth Token ID (BTID). In addition to this, the present invention establishes a three-dimensional map indoors or outdoors (e.g., different floors of a building) for positioning. It can also be used to allow the user to directly adjust the brightness or color of the LED lamp with the Bluetooth communication node. For example, when the user wants to control the light source, the user's own dedicated router should first be connected with the nearby Bluetooth LED light source. After the connection, after the user sends a command to adjust the brightness or color through the router, the LED light can be regulated by the Bluetooth communication.

The present invention uses the communication specification of Bluetooth 4.0 because the past Bluetooth 2.0 or 3.0 basically has a connection time of several seconds, and the connection speed of the infrared communication remote control is obviously insufficient, and according to the Bluetooth related literature (Texas Instruments CC2540) Low Energy Software Developer's Guide v1.0, 2010) states that Bluetooth Low Energy 4.0 transmits data from no connection to the beginning, at least 7.5 ms, basically obeying the following formula:

Effective link time = (Connection Interval) * (1 + (Slave Latency))

The connection interval is set to a minimum of 6 (7.5 ms) and a maximum of 3200 (4.0 s). Slave latency is set to a minimum of 0 and a maximum of 499.

Therefore, the above-mentioned user can quickly adjust the LED light through the Bluetooth communication by issuing a command such as adjusting brightness or color through the router.

In addition, the Bluetooth 4.0 communication specification has a fast scanning function. Basically, the time required for the master node to scan 40 slave nodes is less than one second. Therefore, the present invention can not only statically locate the user's location but also locate the mobile. In the past, this is Bluetooth 2.0 or 3.0, or a feature that ZIGBEE can't. That is, the present invention proposes an innovative function that can be dynamically positioned indoors.

The smart networking light source of FIG. 5 is purely as a slave node 123, which is a module composed of a Bluetooth low-power chip and a microprocessor. For example, a possible embodiment is to use a Texas Instruments TI CC2540 system. The chip not only has the communication function of Bluetooth 4.0, but also has an 8051 microprocessor, and an ADC converter, which can connect the input of eight sensing signals to connect the environment sensor, and in some embodiments, also can be read on the router. When the Bluetooth identification code of the light source is taken, the measured values of the environmental sensors are simultaneously read and sent to the cloud.

The WIFI of Figure 5 also refers to Wi-Fi Direct, which allows devices to communicate directly with each other without the need to connect to an access point. This not only makes communication between devices easier and faster, but it can be connected anytime, anywhere.

The Gateway 27 of Figure 5 can be a home computer, a PC, a laptop, a mobile phone, a tablet, etc., because these devices have built-in BT4.0+WIFI combination chips, through their wired or wireless Internet access functions. Become a Gateway 27, so you can easily connect to the Cloud 28 computing service.

Although the router of FIG. 5 is mainly a portable or wearable embodiment, some of the routers may also be fixed. In other words, the portable router is further fixed indoors and outdoors without hindering people or things. The mobile location becomes a fixed router, which can be connected by the WIFI of the gateway and the WIFI of the fixed router. That is to say, even if no personnel is equipped with a router to provide commands under the smart network light source, it can be remotely Through the Internet and the cloud, the WIFI of the gateway is connected with the WIFI of the fixed router, and then the Bluetooth dual-mode node of the fixed router monitors and regulates all the devices with the Bluetooth node in FIG. For example, the LED light source can be dimmed or tinted or turned on or off; the sensor on the LED light source can be read, and the electrical appliance with the Bluetooth interface can be turned on or off, or monitored, etc.; Monitored or ordered.

As shown in Figure 6, if the spatial range of the smart networked light source layout is not large, and the distance of the Bluetooth communication can reach 10-30 meters, then the Gateway 77 built-in BT4.0+WIFI combination chip can directly Through its Bluetooth 4.0 interface, LED light source 51-59 with Bluetooth node or electrical appliances or sensors 61-69 or robots are monitored and regulated.

Although the above description is mainly based on a person as a user, in reality, the user can generally refer to a pet, an animal, a robot, an important device, a mobile vehicle, and the like as long as the user wears the router of the present invention.

[router]

The term "router" as used in the present invention refers to a device having at least Bluetooth communication and WIFI communication functions, and further enables the device to have a preferred embodiment, as shown in FIG.

1. The wrist strap device 30 is lightweight and waterproof and can be worn on any occasion (the wrist strap is not shown).

2. It has a microcontroller 31 or a microprocessor as a control unit and is connected to other circuit modules.

3. LCD / or touch screen, as display 32

4. The Bluetooth BT4.0 communication module 33 provides identification and communicates with an external LED light source 41 having a Bluetooth 4.0 function or a wearable sensor 39 with a built-in Bluetooth 4.0 function.

5. In the WIFI environment 40, the WIFI communication module 34 can be directly connected to the cloud wirelessly, and the sensing value of the wearable sensor 39 is transmitted to the cloud. The transmission power of the WIFI communication module 34 is adjustable to avoid excessive power consumption.

6. At least one microphone 35 provides an input interface and an output interface for voice recognition, combined with Cloud Speech Recognition (CSR) operations; can be directly rescued by voice; and has a recording function.

7. Built-in speaker 36, can be used as a voice transmission interface, can be called by friends or relatives or caregivers, similar to walkie-talkies, but mainly by the cloud and wireless network, without the need to pay through the system. Speakers can also be transmitted via Bluetooth headsets.

8. It can collect environmental sensor information around Bluetooth 4.0 function to help determine whether it is harmful to personal physique.

9. The power supply 38, which supplies the power required for the circuit components of the wristband router 30, is generally more suitable for the battery.

10. Use low-power circuit components to extend battery replacement or charging time.

Further, you can

1. Built-in accelerometer 37 to record the user's activity

2. Built-in heartbeat measurement to know the user's activity intensity (not shown)

3. Vibratory power generation function with shaking arm power generation for emergency use. (not shown)

4. Has the function of watch display time and so on.

In terms of positioning, with the adjustable color light LED light source in the room and the improved triangular positioning technology proposed above, the indoor positioning function can be achieved after the operation.

Again, the wristband router can scan the Bluetooth identification code (BTID) of nearby LED lights and send it to the nearby gateway (GATEWAY) or the cloud via WIFI, just like a university or hospital or hotel. You can use WIFI to access the Internet at any time, and then the cloud will send the calculated information or knowledge to the user via WIFI or send it to the relevant care or monitoring personnel. If it is sent back to the user, it can be used for navigation.

The advantage of this method is that the LED light can be replaced at any time. After the replacement, the user reads the BTID and RSSI using the program of the wristband router, and then uploads the cloud to set the BTID of the LED light and its space coordinates on the displayed screen. Just fine.

It is worth noting that the above wristband router can achieve the same function if using a mobile phone with BT4.0. For example, support android 4.0 or above mobile phones, HTC one V, X, etc., or iPhone 4S. Just write an app to your phone. Of course, the above wristband router also needs to have an operating system and a working program. The purpose of using the wristband router is to provide the necessary functions, does not require the function of photo photography, does not require a large screen, does not require long-range wireless communication capabilities, such as GSM, GPRS, 3G, 4G, etc., has a waterproof design, can be any Occasionally worn.

Assume that the future world will inevitably have WIFI everywhere, especially in densely populated cities or homes, offices, schools, etc. Based on this, people in this kind of environment do not need to directly connect to the cloud through GSM, 3G, 4G and other functions, only need to be able to connect to the WIFI AP, which can greatly reduce communication costs, and even free.

The wearable sensor on the body is basically designed to meet the needs of convenience, low power consumption and low cost, so it is mainly based on Bluetooth 4.0 (BLE), but there must be a router on the body, which can be worn by the sensor. The signal transmitted by the signal is transferred to the cloud. The router basically has to meet the requirements of light and convenient wearable. Although the function of the smart phone completely includes the basic requirements of the router proposed by the present invention, the smart phone is bulky. Not easy to wear, it consumes a lot of power and is not waterproof. Therefore, the router basically reduces the smart phone, and develops it into a low-level LCD display screen that is only commonly used in general electronic watches. There is no GSM, 3G, 4G and other functions. As long as the function of the router is available, the cost can be greatly reduced. And the power consumption can be greatly reduced, and the volume will be greatly reduced.

For the wristband router, using the speaker instead of the earphone can simplify the equipment, which means that the measurement result of the wearable biomedical sensor can be directly transmitted by the sound, and people often use the eye when working. For example, driving, you can listen to music or chat with people while watching the road. On the other hand, the results of the query can be conveyed by the speaker, and the effect can be achieved. Furthermore, if you are talking to a person or translating, you can still use the wristband router as a mobile phone, at least as a walkie-talkie. The reason is that the combination of the microphone and the speaker with the WIFI interface of the router allows the router to have the function of the walkie-talkie like the mobile phone, mainly through the WIFI and the Internet to connect, for example, through software programs such as Skype or Viber.

By means of the voice recognition function of the router referred to in the present invention, the user can turn on the LED light of the living room by voice command while lying on the bed, and can also adjust the color thereof, and the voice command such as "living room headlight, blue" color". It is also possible to command the washing machine to start up with a voice command such as "Washing Machine, Startup". Or "living room computer, boot".

Speech recognition can be divided into two stages. For common imperative speech, basically, it is still identified by the built-in voice database. If it is not recognized, it will be uploaded to the cloud for processing, and then returned, the current iPhone. 4S is the voice secretary function through the network. For the sentences commonly used by the host, it can also be statistically included in the voice data library of the voice device that is worn by the user, and the unusable voice data is deleted to maintain the database. Streamlined, and the speed of the search.

Embodiment 1 Tone light function, refer to Figure 5

1. The wristband router or mobile phone (master node) scans the LED lights with Bluetooth 4.0 slave nodes nearby, selects the target lights for the pictures or texts displayed on the screen, and loads the dimming requirements into the corresponding lights. The content of the dimming requirements, for example green, red, blue, yellow.

2. , , , Connected or connected at the same time, the wristband router or mobile phone (master node) can write the Bluetooth 4.0 slave node in the LED light to make the microcontroller inside change the color of the LED as required.

Embodiment 2 Positioning function: case (1), refer to Figure 5

1. The router scans the Bluetooth slave nodes BTID and RSSI of the nearby LED light source, such as 4, 7, 5, 8; or The router scans the Bluetooth slave nodes BTID and RSSI of the nearby LED light source, for example, 3, 6, 11, 14;

2. The router sends the four Bluetooth slave nodes BTID and RSSI data to the WIFI AP or the gateway 25 through the WIFI, and then to the Internet or the cloud 26. The router sends the four Bluetooth slave nodes BTID and RSSI data to the WIFI AP or the gateway 27 through the WIFI, and then to the Internet or the cloud 28.

3. Perform calculations in the cloud and compare them with the preset three-dimensional space map of the Bluetooth slave nodes using triangle positioning technology. router, The three-dimensional coordinates of the location of the router, as well as the room to determine whether it is located in a special property, such as a bathroom or kitchen. Or a confidential room or a controlled room.

4. Return the location to router, router. Or further refer to the caregiver or the controller, or even ask again router, The router provides the sensed value of the wearable sensor on its user or the ambient sensor sensed value on the LED source nearby.

Positioning function: case (2), refer to Figure 5

1. The router scans the Bluetooth slave nodes BTID and RSSI of the nearby LED light source, such as 6, 9, 14, 17;

2. The router sends the four Bluetooth slave node BTID and RSSI data, and the environmental sensor sensed values of the LED light sources 14, 17 to the WIFI AP or the communication gate 27 through the WIFI, and then to the Internet or the cloud 28 .

3. Perform calculations in the cloud and compare them with the preset three-dimensional space map of the Bluetooth slave nodes using triangle positioning technology. The three-dimensional coordinates of the location of the router, as well as the room to determine whether it is located in a special property, such as a bathroom or kitchen. Whether it is a confidential room or a controlled room, etc., and based on the environmental sensor sensed values of the LED light sources 14, 17 to determine whether the environment is in a dangerous situation, such as the air contains too much carbon dioxide, showing poor ventilation; or Excessive amounts of carbon monoxide indicate poor ventilation and are dangerous to be disposed of as quickly as possible.

4. Return the location to Router, further reference to caregivers or controllers, requirements The wearer of the router is processed as soon as possible, and the above steps continue to track until the crisis is lifted.

In the above case (2), of course The wearable sensors on the wearer of the router can also be transmitted to the cloud for monitoring and management, and provide users with appropriate disposals in real time.

Further, an APP or a program capable of adjusting an LED lamp can be developed. The function is that when the user wakes up or moves at night, the mobile phone or router worn by the user can quickly establish the connection and read by scanning the RSSI value of the nearby LED lamp. Take the nearest LED light, if it is bright enough, then turn it on to avoid falling and falling. That is to say, the intelligent networking positioning function referred to in the present invention also has the basis of intelligent energy saving to turn on or off the electric lamp or the air conditioner or the electrical appliance, and achieves the safety and comfort, and can simultaneously turn off the power to achieve the purpose of energy saving and carbon reduction.

With the IoT of LED light sources, people with wristband routers or mobile phones can be positioned in a triangle to know if they are close to on-site applied electrical appliances (slave nodes) and by communication gates ( GATEWAY) determines whether the electrical appliance is in hibernation, sleep, or wake up. On-site applied electrical appliances include air conditioning systems such as electric fans, electric heaters, air conditioners, lights or lighting, computers or televisions, and the like. Knowing the location of the user, especially the distance-on-site electrical appliance, determines whether the on-site applied electrical appliance is hibernating, sleeping, or calling. The basis for waking up. As shown in FIG. 8, according to the time required for the cold start or warm start of the electrical appliance 100, and the speed at which the general user 120 walks, the distance can be estimated or the size of the RSSI can be directly determined whether the appliance is turned off or started. The distance between the user 120 and the electrical appliance 100 can be divided into a growth distance zone 107, a first buffer zone 106, a medium distance zone 105, a second buffer zone 104, a short distance zone 103, and electrical appliances such as televisions or computers or air conditioners usually because of the boot time. Long, there is a cold start or a warm start, so

A) when the position of the user 120 is in the short distance zone 103, the electrical appliance 100 is in use;

B) when the position of the user 120 is in the middle distance zone 105, the electrical appliance 100 is in a warm start standby state;

C) when the position of the user 120 is in the long distance zone 107, the electrical appliance 100 is in a shutdown state;

D) When the position of the user 120 is in the first buffer zone 106, the moving speed can be positive and enter the middle distance zone 105, so that the electrical appliance 100 is switched to the warm start; if the moving speed is negative and enters the long distance zone 107, the electrical appliance 100 is switched to the off state; if otherwise, the electrical appliance 100 maintains the original state;

E) When the position of the user 120 is in the second buffer zone 104, the moving speed can be positive and enter the short distance zone 103, so that the electrical appliance 100 is switched to the use state; if the moving speed is negative and enters the middle distance zone 105, the electrical appliance 100 is switched to the warm start state; if otherwise, the electrical appliance 100 maintains the original state.

For example, for an LED lamp, there is no need to have a warm start state. When the user 120 leaves the short distance zone of the LED lamp 100 more than three meters and the speed is negative (representing the exit speed), the lamp is turned off. Conversely, if the user 120 approaches the short distance zone of the LED light 100 less than three meters and the speed is positive (representing the approach speed), the light is illuminated.

Embodiment 3, the function of map and navigation

For the indoor light source BTID map and navigation, referring to FIG. 5, it can be implemented as follows.
