Description

[0001] The present invention relates to an addressable automatic fire alarm system,

The present invention relates to an address type automatic fire detection system, and more particularly, to an address type automatic fire detection system including an address type fire detector having an address function and address sending function, Type address receiver having an address receiving function, so that an address signal can be transmitted from an address type fire detector to an address type receiver through a power line communication of a multiplex communication method when a fire detection or a non-resetting (detector malfunction) occurs, To an addressable automatic fire detection system that allows precise location addresses of fire occurrences to be precisely represented by boundary zone numbers and detector numbers.

With the development of society, safety consciousness to protect their own property and life has been increasing many times in a big and small fire, and the perception of firefighting has changed, and the importance of firefighting facilities for prevention and boundary of fire has become more important. to be.

The automatic fire detection system of firefighting facilities automatically detects the combustion products generated in the fire automatically through the fire detector and transmits the fire signal to the fire receiver, and the receiver notifies the fire fact through fire alarm or sound device, Is the most important fire fighting facility that can minimize the damage caused by fire by operating interlocked facilities (fire fighting equipment, smoke control equipment, emergency broadcasting equipment, etc.).

Currently, domestic automatic fire detection systems are classified as P type automatic fire detection system using P type receiver and R type automatic fire detection system using R type receiver. However, current automatic fire detection facilities have a deteriorated adaptability in order to minimize the fire damage in a fire generated in a specific fire prevention object having a complicated internal structure.

In other words, in case of detectors used in automatic fire detection facilities, since P type and R type automatic fire detection systems using a general type detector having no address function in case of fire are installed, only a wide range of fire positions in the boundary zone unit is displayed, In order to grasp the exact fire position, it is necessary for the person and the manager to directly enter into the complex boundary zone and check the fire position individually. .

For example, businesses such as karaoke rooms, motels, night life pubs, gyohwon, massage parlors, telephone rooms, indoor golf driving range, etc. are becoming more and more dangerous due to complex internal structures and compartmentalized and unspecified persons. In other words, due to the nature of the business, the high-rise and underground phenomenon is accelerated, and the interior of the room is shaped and has a narrow passage. Therefore, it is very difficult to find the accurate fire position in case of fire, Is very large.

In addition, premises such as karaoke, motel, night club, gyohwon, massage parlor, telephone room, indoor golf driving range, etc. have a complicated internal structure like maze due to the tendency to enjoy closeness and covertness, so early detection of fire is also important. An address type automatic fire detection system using address type detectors that can quickly and accurately grasp the location of a fire in the event of a fire is most needed.

However, due to the lack of research and development of address type automatic fire detection equipment, most of the multi-use facilities have been using only general type automatic fire detection system using the general type sensor applied 20 years ago. As a facility for reducing fire damage within a specific fire fighting object having compartmentalization, adaptability is considerably reduced.

In other words, in the case of a general type automatic fire detection system using a general type detector, since only the boundary zone position of the floor unit and the area unit is displayed, it is difficult for a firefighting professional to quickly and accurately determine a fire position in case of a fire. Therefore, It is a reality that related persons and managers of specific fire fighting objects have difficulty in precisely locating and coping with fires.

FIG. 1 shows a block diagram of a general type automatic fire detection system showing a circuit connection of a conventional general type detector and P type and R type receivers.

As shown in FIG. 1, most fire detectors manufactured in Korea are characterized in that they are operated by a simple ON / OFF function in a circuit configuration. In case of a fire, the general type fire detector 11 Heat, smoke) perform only the role of a simple switch function. Therefore, the display of the earth window of the P-type receiver 12 and the display of the R-type receiver 13 does not display the detailed fire position in units of sensing zones in the boundary zone, , It is very difficult to find a precise fire position in fire and fire alarm. In addition, as shown in FIG. 2, when one of the plurality of general type fire detectors 11 connected in parallel on the same loop is operated, the other detectors have a problem of operation limit that does not operate even under normal operating conditions.

In order to overcome the problem of the automatic fire detection system composed of the general type fire detector 11 and the general type receivers 12 and 13, an analog type sensor having an address type function has been developed and marketed in Korea. However, Detectors can be applied only to R type receivers, and they are difficult to commercialize because they are distributed in the range of 5 ~ 100 thousand won, which is much higher than the price of general type detectors. In particular, the analog type R-type receiver that can be interlocked with the analog type detector is limited to a large-scale high-rise building and a large-scale apartment complex because the price is about 10 million won, which is a limit to generalization.

In addition, since businesses such as karaoke, motel, night club, gyohwon, massage parlor, telephone room, golf driving range are mainly used for P type automatic fire detection equipment, in order to work with analog type detectors, It is economically burdened because it needs to be replaced with expensive R type automatic fire detection system and it is practically impossible to replace all the refractory wiring used before with a shield line.

FIG. 6 is a schematic block diagram of an address type fire detection system according to the present invention, FIG. 2 is a functional block diagram showing the configuration of a photoelectric port type address smoke detector applied to the present invention.

4, the differential type spot-type thermal sensor 110 includes a first NTC thermistor 111 for sensing the internal temperature of the sensor and a second NTC thermistor 112 for sensing the external temperature of the sensor. A DIP switch 114 for setting the sensor number of the sensing zone unit installed in the boundary zone to one of 01 to 99 as a binarized decimal input method, and a DIP switch 114 for setting the DIP switch 114 (Not shown). When an event of fire occurrence or non-fire occurrence occurs, the fire detection or non-fire return signal is transmitted to the address type A controller 115 for transmitting an address signal of a detector number in response to a count pulse signal transmitted to the receiver 200 to inform the boundary zone number and then requesting the address of the detector from the addressed receiver 200, It can comprise.

That is, the differential type spot-type address type thermal sensor 110 uses two NTC thermistors having a negative temperature coefficient as the fire sensor 113 and uses the difference of the input voltage according to the temperature change. In the case of the differential type spot type address type thermal sensor 110, the controller 115 receives a DC voltage of 24 V from the addressable receiver 200, and at the same time, the controller 115 outputs a DIP switch 114, (T-in) by using the first and second NTC thermistors 111 and 112, which are normally fire sensors 113, and stores the detected temperature in the internal flash memory ) And the external temperature (T-out) at regular intervals (for example, 2 seconds).

At this time, when a fire occurs, the temperature difference (Td = T2-T1) measured by the first NTC thermistor 111 for detecting the internal temperature and the temperature T2 measured by the second NTC thermistor 112 for sensing the external temperature is If a Td of 30 or more according to the detector type approval criterion is generated, the comparator (Comparator) in the controller 115 is used to read out the fire, and the address type receiver 200 is connected to the fire signal .

Next, the address type receiver 200 reads the number of the circuit loop to detect the boundary zone number in which the fire has been detected, and the address of the differential type spot type address type thermal sensor 110 operated again in the circuit loop in which the fire signal is input And the controller 115 of the corresponding differential type spot type address type thermal sensor 110 transmits a count pulse signal requesting its own address to the digital And transmits the converted pulse to the address type receiver 200.

5, the constant-temperature six-port type address type thermal sensor 120 includes a fire sensor 122 having an NTC thermistor 121 having a negative temperature coefficient, A DIP switch 123 for setting the detector number to one of 01 to 99 as a binary decimal input method, and a detector number, which is an address set by the DIP switch 123, to an internal flash memory (not shown) When an event of fire occurrence or non-fire occurrence occurs, a signal of fire occurrence detection or non-fire resetting is transmitted to the address type receiver 200 through the corresponding connected circuit loop to inform the boundary type number, And a controller 124 for transmitting the address signal of the sensor number in response to the count pulse signal requesting the address of the sensor from the controller 200.

At this time, when the external temperature sensed through the NTC thermistor 121 of the fire sensor 122 is raised to a temperature (for example, 70) which is a sensor type approval criterion, the controller 124 controls the internal analog digital converter ) Is used to read the fire.

That is, except for using one NTC thermistor 121 as the fire sensor 122, the configuration and operation principle of the DIP switch 123 and the controller 124 are the same The same as the differential type spot-type address type thermal sensor 110 described above, so that unnecessary repetitive description will be omitted.

As shown in FIG. 6, the photoelectric port type address smoke detector 130 includes

A fire sensor 133 having an infrared LED for emitting infrared light at a set frequency and a photocell 132 for receiving an infrared light scattered by smoke during a fire to generate an electromotive force; A DIP switch 134 for setting the detector number to one of 01 to 99 as a binary digitized decimal input method, and a detector number, which is an address set by the DIP switch 134, to an internal flash memory (not shown) When an event of fire occurrence or non-fire occurrence occurs, a signal of fire occurrence detection or non-fire resetting is transmitted to the address type receiver 200 through the corresponding connected circuit loop to inform the boundary type number, And a controller 124 for transmitting the address signal of the sensor number in response to the count pulse signal requesting the address of the sensor from the controller 200.

7 shows an example of a signal waveform for transmitting a detector number between an address type fire detector and an address type receiver in the address type automatic fire detection system according to the present invention.

As shown in FIG. 7, when one of the address type fire detectors 100 detects a fire and operates the fire type fire detector 100 and the address type receiver 200, Information transmission begins on the basis of power line communication. That is, the address type receiver 200 transmits a count pulse signal of a regular interval (RI) requesting the address of the operated detector to the corresponding circuit loop, and the operated address type fire detector 100 counts the count pulse And compares it with its own address to know when to send the detector number to the addressable receiver 200. At this time, the information of the detector number transmitted from the operated address type fire detector 100 to the address type receiver 200 is an address signal sent only when a fire is detected.

That is, after the first count pulse serving as a reset is generated, the first address type fire detector 100 can transmit the address signal of the detector number during RI1. No signal is seen during the first RI1, which means that the first address type fire detector 100 is in a normal state. After the RI1, the address type receiver 200 generates a count pulse (2nd pulse) again, and the address type fire detector 100 can transmit an address signal to the address type receiver 200 from this time. No signal is seen during RI2, which means that the second address type fire detector 100 is also in a normal state. The address type receiver 200 again generates a count pulse (third pulse), and the address type fire detector 100 can again transmit the address signal to the address type receiver 200 from this time. When the address type fire detector 100 detects a fire, as shown in FIG. 7, the three address type fire detectors 100 send an address signal pulse to the address type receiver 200 . Accordingly, the address type receiver 200 reads the address type fire detector 100 that transmitted the fire signal three times. In this way, the address type receiver 200 generates the last pulse and finds the address of the address type fire detector 100 that sends the fire signal. In the present invention, 1 scan is referred to as 1 scan until the next pulse signal is issued from the 1st pulse, a pulse indicated by the solid line is the count pulse generated by the addressed receiver 200, And the address signal pulse generated by the address type fire detector 100 of No. 5 and No. 5.

At this time, the power module 211 further includes a spare power source (battery) for supplying power to the address type smoke detectors 100 and the address type receiver 200 even in an emergency in which the supply of the power is interrupted at all times .

The input module 212 receives an address signal corresponding to occurrence of a fire detection or non-return signal under the power line communication of the multiplex communication type with the address type fire detectors 100, and outputs the address signal to the main module 218.
