Description

  The present invention relates to an alarm device for notifying an abnormality in a monitoring area and a device abnormality by a voice message, and more particularly to an alarm device capable of reducing the memory capacity of a voice data memory.

  Alarms that detect abnormalities in the monitoring area, such as a fire, and detect device abnormalities, such as a battery voltage drop, and output a voice message indicating the abnormalities in the monitoring area and the abnormalities of the apparatus are known (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2004-054356 (FIGS. 2 and 3)

  By the way, as described above, in which a voice message indicating a monitoring area abnormality or a device abnormality is output, it is estimated that a voice message having a high importance (high urgency) such as a monitoring area abnormality or a usage frequency is large. Voice messages to be sent require high quality and clarity to the user, but other voice messages have high importance (high urgency) or are estimated to be used frequently Not so high quality and clarity are not required.

  Conventionally, however, various voice messages are stored in the voice data memory as voice data created at the same large bit rate regardless of their importance and estimated usage frequency. Was necessary.

  It is an object of the present invention to reduce the memory capacity of a voice data memory of an alarm device that informs a monitoring area abnormality or device abnormality by a voice message.

(1) An alarm device according to the present invention includes an abnormality detection unit that detects an abnormality in a monitoring region, an apparatus state detection unit that detects normality or abnormality of the device, and an audio indicating abnormality in the monitoring region and normality or abnormality of the device. A voice synthesis circuit that synthesizes voice data and outputs a voice message by synthesizing the voice data, which stores voice data created at different bit rates depending on the importance of the voice message or an estimated usage frequency. And a speaker that outputs a voice message to the monitoring area, and a voice control circuit that outputs a selection signal of voice data indicating abnormality of the monitoring area and normality or abnormality of the device to the voice synthesis circuit.
(2) In the alarm device according to the present invention, the bit rate of the voice data related to the voice message indicating the abnormality in the monitoring area is set higher than the bit rate of the other voice data.
(3) In the alarm device according to the present invention, the bit rate of the voice data related to the voice message indicating the normality of the device is larger than the bit rate of the other voice data.
(4) In the alarm device according to the present invention, both the bit rate of the voice data related to the voice message indicating abnormality of the monitoring area and the bit rate of the voice data related to the voice message indicating normality of the device are bits of other voice data. It is larger than the rate.
(5) In the alarm device according to the present invention, the voice control circuit determines whether the device is normal or abnormal based on the detection result of the device state detection unit at the time of inspection input. The voice data selection signal is output to the voice synthesis circuit, and if the device is normal, the voice data selection signal indicating that the device is normal is first output to the voice synthesis circuit. If there is an input, the audio data selection signal indicating abnormality of the monitoring area is output to the voice synthesis circuit following the output of the audio data selection signal indicating normality of the device.

(1) According to the alarm device according to the present invention, since the voice data created at a different bit rate according to the importance of the voice message or the estimated usage frequency is stored in the voice data memory, the abnormality in the monitoring area, It is possible to reduce the memory capacity of the voice data memory of the alarm device that notifies the normality or abnormality of the device by a voice message.
(2) According to the alarm device of the present invention, a high bit rate is used for a voice message indicating an abnormality in a monitoring area that is highly important (highly urgent) and requires high quality and clarity. Other voice messages that are not important (not urgent) and do not require much sound quality are voice data using a small bit rate. Compared to the conventional case where all audio data is stored using the bit rate, the required memory capacity can be reduced, and if there is an abnormality in the monitoring area, this can be clearly notified. it can.
(3) In the alarm device according to the present invention, a voice message indicating normality of a device that is estimated to be used frequently and requires high quality and clarity is voice data using a large bit rate. Another voice message that does not require high frequency of use and does not require much attention to sound quality is voice data that uses a small bit rate.
It is recommended that equipment is inspected at intervals of about one month. For this reason, it is considered that the voice message indicating the normality of the device is frequently used. Therefore, the voice message indicating the normality of the device is voice data using a large bit rate. As a result, a voice message indicating the normality of the device can be output with high quality and clarity, and it can be clearly notified that the device is normal.
(4) According to the alarm device according to the present invention, the voice message indicating the abnormality of the monitoring area having high importance (high urgency), high quality and clarity, and the estimated usage frequency are high. Both voice messages indicating normality of devices that require high quality and clarity are voice data using a large bit rate, but the importance (urgentness) and estimated usage frequency are not high. Other voice messages that do not require much sound quality are voice data using a small bit rate, so compared to the conventional case where all voice data is stored using a large bit rate. The required memory capacity can be reduced, and when there is an abnormality in the monitoring area, or when the device is in a normal state at the time of inspection, this can be clearly notified.
(5) According to the alarm device of the present invention, the user can confirm the normality / abnormality of the device by inspection input, and when the device is normal, after confirming that the device is normal, the user continues further. Only by continuing the inspection input, it is possible to confirm whether or not the voice message indicating the abnormality in the monitoring area is normally output.
Conventionally, a voice message indicating that the monitoring area is abnormal is output as a voice message indicating that the device is normal. However, since the voice message indicating that the device is normal is output separately from this voice message, the device is normal. It is easy for the user to understand that there is. Here, the amount of memory required for data increases as much as the addition of a voice message indicating that the device is normal, but the voice data of the voice message indicating that the device is normal indicates an abnormal monitoring area. If the bit rate is smaller than the voice data of the voice message and stored in the voice data memory, the increase in memory can be minimized.

  FIG. 1 is a block diagram showing the configuration of a fire alarm as an alarm device according to an embodiment of the present invention, FIG. 2 is a flowchart showing the overall operation, and FIG. 3 is a flowchart showing a switch input determination operation in FIG. 4 is a flowchart showing the fire monitoring operation in FIG. 2, FIG. 5 is a flowchart showing the disconnection monitoring operation in FIG. 2, FIG. 6 is a flowchart showing the battery voltage drop monitoring operation in FIG. 2, and FIG. It is a flowchart which shows the monitoring result output operation | movement inside.

  In FIG. 1, 1 is a power source for driving various circuits and devices, for example, a 6V battery, 2 is a power supply monitoring circuit that monitors the voltage of the battery 1, and 3 is a power supply that is closed when the voltage of the battery 1 is monitored. A switch circuit 4 for supplying power to the monitoring circuit 2 is a constant voltage circuit, and has a function of supplying a constant voltage (for example, 3 V) that does not vary depending on the voltage of the battery 1 to each circuit from here on. Reference numeral 5 denotes a thermal fire detection unit including a thermistor 6 and a resistor 7. Moreover, the fire detection part 5 is utilized also for disconnection detection. Incidentally, there are two types of thermistors 6: a type in which the resistance value increases as the temperature a rises and a type in which the resistance value decreases as the temperature b increases. Here, the b type is used, and the b type thermistor. If the detected voltage value is equal to or greater than a fire detection threshold (for example, 2 V), it is determined that a fire has occurred.

  Reference numeral 8 denotes a switch in which a current limiting resistor 9 is connected in series. When the switch 8 is turned on, an abnormality monitoring result is output from the speaker 11, and a fire phrase (fire sound) is predetermined in case of a fire. It is supposed to be stopped for hours.

  Reference numeral 12 denotes a microcomputer (hereinafter referred to as a microcomputer), which corresponds to the voice control circuit of the present invention, and includes a storage unit 13 and a timer 14 for performing various processing operations. Reference numeral 15 denotes a voice synthesizing circuit including a voice data memory 15a in which voice data (voice data a to f to be described later) of voice messages indicating abnormality of the monitoring area and normality or abnormality of the device is stored. Thus, the voice of various phrases is output from the speaker 11. Reference numeral 16 denotes a switch circuit for supplying power to the voice synthesis circuit 15 that is closed when the voice synthesis circuit 15 outputs voice.

  Here, as an abnormality detection unit for detecting an abnormality in the monitoring area, a fire monitoring unit (comprising a fire detection unit 5 and a microcomputer 12) for detecting a fire is provided, and device status detection for detecting normality / abnormality of the device. Here, a disconnection monitoring unit (configured by the fire detection unit 5 and the microcomputer 12) for detecting a failure of the fire detection unit 5 and a battery voltage drop monitoring unit (the power supply monitoring circuit 2 and the microcomputer 12) for detecting a battery exhaustion are here. It comprises).

More specifically, in the storage unit 13 of the microcomputer 12, a fire flag 13a that is set when a fire is detected, a disconnection flag 13b that is set when a disconnection is detected, and the voltage of the battery 1 is equal to or lower than a predetermined voltage value. For example, a voltage drop flag 13c that is set when it is detected that the voltage has dropped to 5 V or less is stored, and the microcomputer 12 outputs a sound to the voice synthesis circuit 15 based on the result of each monitoring process. A sound output command signal LM is added to a selection signal L1 to L6 for various audio data and output. Here, the selection signal L1 is a signal for selecting the fire sound data a “Woo Wang Can Can Fire is Fire” (created at a bit rate of 128 kbps) that is output when a fire breaks out. The selection signal L2 is approximately 50 when the battery voltage drops. The selection signal L3, which is a signal for selecting the device abnormal voice data b “pip” (created at a bit rate of 32 kbps) to be output every second, is selected as the device abnormal voice data c “pip pip” that is output about every 50 seconds when the fire detection unit fails "Selection signal (created at a bit rate of 32 kbps), selection signal L4 is a signal and selection signal for selecting device normal voice data d" pick is normal "(created at a bit rate of 128 kbps) at inspection input (switch 8 input) L5 is the device abnormal voice data e at the time of inspection input (switch 8 input) e “Pic battery is out of service” (bit rate 6 Selection signal L6 is a signal that selects the device abnormal voice data f “Pippi pip fault. Please contact the dealer” (created at a bit rate of 64 kbps) at the time of inspection input (switch 8 input). It is. The signal LB is a signal (back signal) notifying the microcomputer 12 that the commanded selection sound has been output from the voice synthesis circuit 15.
Here, the device normal voice data d “Pick is normal” is the voice data of a phrase shorter than the fire voice data a “Woo Kang Kang is a fire,” and the device normal voice data d “Pip is normal.” Is an example, and other audio data may be used as long as it is easy for the user to understand that the device is operating normally.

  As described above, of the voice data a to f, the voice data that is desirably output as high quality and clear, for example, voice data of a voice message indicating a monitoring area abnormality having high importance (high urgency). a and voice data d of a voice message indicating normality of a device estimated to be used frequently are created at a large bit rate (128 kbps) and stored in the voice data memory 15a, while the other voice data Is generated at a bit rate (64 kbps or 32 kbps) having a smaller value and stored in the audio data memory 15a. Therefore, the required memory capacity can be reduced compared to the conventional case where all audio data is stored using a large bit rate.

  Here, the voice data memory 15a stores each voice message as one voice data, but since there is a common voice phrase part, it is stored as voice data for each voice phrase. It may be. In this case, the microcomputer 12 may output, to the voice synthesis circuit, a selection signal of voice data of various voice phrases used for the voice message in accordance with the voice message to be output.

  At the time of this sound output, the microcomputer 12 turns on the switch circuit 16 to supply power to the speech synthesis circuit 15, and after outputting the sound, turns off the switch circuit 16 to stop power supply to the speech synthesis circuit 15. As a result, power consumption is reduced. Similarly, during the battery voltage drop monitoring process, the microcomputer 12 turns on the switch circuit 3 to supply power to the power supply monitoring circuit 2 and inputs the voltage of the battery 1 from the power supply monitoring circuit 2. The power consumption is reduced by turning off and stopping the power supply to the power monitoring circuit 2.

  Further, the microcomputer 12 as the voice control circuit determines whether the device is normal or abnormal based on the detection result of the device state detection unit (disconnection monitoring unit, battery voltage drop monitoring unit) at the time of inspection input, and the device is abnormal. In such a case, a sound data selection signal (selection signal L5 or L6) indicating an abnormality of the corresponding device is output to the speech synthesis circuit 15, while when the device is normal, the device The voice data selection signal L4 indicating normality is output to the voice synthesis circuit 15, and when the inspection input is continuously input for a predetermined time or longer, the voice data selection signal L1 indicating abnormality in the monitoring area is output to the voice synthesis circuit 15 It is configured to output to.

  Next, the operation of the alarm device of this embodiment, that is, the fire alarm device, will be described with reference to FIG. 1 based on FIGS. First, in FIG. 2 showing the main flowchart, when the battery 1 is set (loaded) and the power is turned on, all flags 13a to 13c of the microcomputer 12 in FIG. The symbol is omitted) (step S1), and the counter of the timer 14 is cleared (step S2). Next, in step S3, a switch input determination process is performed to determine whether or not there is an input from the switch 8. In step S4, a fire monitoring process is performed to determine whether a fire has occurred. In step S5, the thermistor 6 is checked. A disconnection monitoring process for determining whether or not there is a disconnection is performed, a battery voltage drop monitoring process is performed in step S6, and then a monitoring result output process is performed in step S7, followed by a switch input in step S3. Return to determination processing. And the process of step S3-step S7 is repeated.

In the switch input determination process (step S3), as shown in FIG. 3, first, it is determined whether or not there is an input from the switch 8 (whether or not the switch 8 is closed) (step S311). (I.e., proceed to the fire monitoring process of step S4 in the main flowchart of FIG. 2).
If it is determined in step S311 that there is an input from the switch 8, then it is checked whether or not the disconnection flag is set (step S312). If the disconnection flag is set, the failure voice “pippi pip fault Please contact the dealer ”is output once (step S313), and the process is terminated (proceed to step S4 in the main flowchart).
If it is determined in step S312 that the disconnection flag is not set, it is next checked whether or not the voltage drop flag is set (step S314). If the voltage drop flag is set, the battery is dead. A process for outputting the voice “Battery is out of battery. Please contact the dealer” once is performed (step S315), and the process is terminated (proceed to step S4 in the main flowchart).
If it is determined in step S314 that the voltage drop flag has not been set, then it is checked whether or not the timer count has been started for 3 seconds (step S316), and the timer count has been started for 3 seconds. If not, after processing for outputting the normal voice “pick is normal” once (step S317), the timer starts counting for 3 seconds (step S318). Next, check if 3 seconds have passed (step S319). If 3 seconds have not passed, return to step S311. If 3 seconds have passed, fire sound "Woo Wang Can Can Fire is Fire". After processing for outputting once (step S320), the timer counter is cleared for 3 seconds (step S321), and the process returns to step S311. If it is determined in step S316 that the timer has started counting for 3 seconds, the process jumps to step S318.
In this way, in the switch input determination process, when it is normal, it can be notified as many times as there are inputs from the switch 8 when it is normal. Therefore, when it is determined that the fire alarm is in a normal state instead of a fire state, a normal sound indicating that the fire alarm is normal is output, and it can be confirmed that the sound is normal by the sound output. If it is determined that a failure sound or a battery exhaustion sound indicating a failure or battery exhaustion is output, it can be confirmed that the sound output is abnormal.
Then, only when you want to confirm the fire sound “Woo Wan Can Kan is a fire”, you only need to press and hold the switch 8, and when you check the normality / abnormality of the equipment by normal inspection input, Sometimes only normal sound “Pip is normal” is output, so the phrase of the sound normally output at the time of inspection input can be shortened (previously the fire sound was output as the sound normally output at the time of inspection input) Accordingly, the power supply time to the speaker 11 can be shortened, the power consumption can be reduced, and an energy saving effect can be obtained.

As shown in FIG. 4, the fire monitoring process (step S4) first takes the voltage value of the thermistor 6, and compares this detected voltage value with a fire detection threshold value (eg, 2V), that is, the detected voltage value. It is determined whether or not a fire has occurred by determining whether or not the fire has exceeded the threshold for fire detection (2V) (step S411). If it is determined that no fire has occurred, the fire flag is cleared. Then (step S412), the process is terminated (that is, the disconnection monitoring process in step S5 of the main flowchart of FIG. 2 is performed).
If it is determined in step S411 that a fire has occurred, the fire flag is set (step S413), and the process ends (that is, the disconnection monitoring process in step S5 of the main flowchart in FIG. 2 is performed).

As shown in FIG. 5, the disconnection monitoring process (step S5) first checks whether or not the fire flag is set (step S511). If the fire flag is set, priority is given to fire detection. The process ends (that is, the battery voltage drop monitoring process in step S6 of the main flowchart in FIG. 2 is performed).
If it is determined in step S511 that the fire flag is not set, it is next determined whether the voltage value of the thermistor 6 is taken in and disconnected (step S512). That is, it is determined whether or not the output of the thermistor 6 is 0V, and it is determined whether or not it is disconnected. If it is not disconnected, the disconnection flag is cleared (step S513), and the process ends (steps of the main flowchart). Proceed to the battery voltage drop monitoring process of S6).
If it is determined in step S512 that the circuit is disconnected, the disconnection flag is set (step S514), and the process ends (the process proceeds to the battery voltage drop monitoring process in step S6 of the main flowchart).

As shown in FIG. 6, the battery voltage drop monitoring process (step S6) first checks whether or not the fire flag is set (step S611). If the fire flag is set, the disconnection monitoring process described above is performed. Similarly, since fire detection has priority, the processing is terminated (that is, the monitoring result output processing in step S7 of the main flowchart in FIG. 2 is performed).
If it is determined in step S611 that the fire flag is not set, whether or not the voltage of the battery 1 has decreased to a predetermined voltage value or lower (in this case, a lower level or lower, for example, 5 V or lower). (Step S612), if not lower than 5V, it is checked whether or not the battery voltage drop flag is set (step S613). If the battery voltage drop flag is not set, the process is terminated ( (Proceed to the monitoring result output process in step S7 of the main flowchart).
If it is determined in step S613 that the battery voltage drop flag is set, the battery voltage drop flag is cleared (step S614), and the process ends (the monitoring result output process in step S7 of the main flowchart). (Proceed)
If it is determined in step S612 that the voltage of the battery 1 has dropped to 5 V or less, it is determined whether or not the battery voltage drop flag is set (step S615), and the battery voltage drop flag is set. Then, the process is terminated (the process proceeds to the monitoring result output process in step S7 of the main flowchart).
If it is determined in step S615 that the battery voltage drop flag is not set, the battery voltage drop flag is set (step S616), and the process ends (the monitoring result output process in step S7 of the main flowchart is performed). ).

As shown in FIG. 7, the monitoring result output process (step S7) first checks whether or not the fire flag is set (step S711). If the fire flag is set, a fire has occurred. Then, the fire sound “Woo Wang Can Kang is a fire is fired” is output (step S712), and the process is terminated (that is, the process returns to the switch input determination process in step S3 of the main flowchart of FIG. 2).
If it is determined in step S711 that the fire flag is not set, it is checked whether or not the disconnection flag is set (step S713). If the disconnection flag is not set, the battery voltage drop flag is next set. Is set (step S714), and if the battery voltage drop flag is not set, the process ends (returns to step S3 in the main flowchart).
If it is determined in step S713 that the disconnection flag has been set, the alarm sound “pip pip pip” is set to be output in a cycle of 50 seconds (step S715), and the process ends (step S3 in the main flowchart). Back to).
If it is determined in step S714 that the battery voltage drop flag is set, the alarm sound “beep” is set to be output at a cycle of 50 seconds (step S716), and the process is terminated (in the main flowchart). Return to step S3).

  As described above, in the alarm device of this embodiment, that is, the fire alarm device, the sound data a to f created at different bit rates according to the importance of the sound message or the estimated use frequency are stored in the sound data memory. Thus, it is possible to reduce the memory capacity of the voice data memory 15a of the alarm device that notifies the abnormality of the monitoring area, the normality of the equipment, or the abnormality by a voice message.

  In addition, a voice message indicating an abnormality in a monitoring area that is highly important (highly urgent) and requires high quality and clarity is voice data a using a large bit rate, while the importance is high. Other voice messages that are not expensive (not urgent) and do not require much sound quality are voice data using a low bit rate, so all voice data is sent using a high bit rate. The required memory capacity can be reduced as compared with the conventional storage, and when there is an abnormality in the monitoring area, this can be clearly notified.

  In addition, a voice message indicating normality of a device that requires a high estimated frequency of use and requires high quality and clarity is voice data d using a large bit rate, while the estimated usage frequency is high. Other voice messages that do not require much sound quality are voice data that uses a small bit rate, so that voice messages that indicate the normality of the device can be output with high quality and clarity. It is possible to clearly notify that the device is normal.

  In addition, voice messages that indicate abnormalities in monitoring areas that require high importance (high urgency), high quality and clarity, and equipment that is estimated to be used frequently and that require high quality and clarity Voice data indicating normality of the voice message a and d using a bit rate of a large value, while the importance (urgency) and the estimated frequency of use are not high and the sound quality is not so much. Since other good voice messages are voice data b, c, e, f using a small bit rate, compared to the conventional case where all voice data is stored using a large bit rate, The required memory capacity can be reduced, and when there is an abnormality in the monitoring area, or when the device is in a normal state at the time of inspection, this can be clearly notified.

  Further, at the time of inspection input by turning on the switch 8, whether the device is normal or abnormal is determined based on the detection result of the device state detection unit. If the device is abnormal, the selection signal L6 of the audio data f indicating the abnormality of the device is detected. If the device is normal, first, the selection signal L4 of the short phrase speech data d indicating the normality of the device is output to the speech synthesis circuit 15, and at this time continuously for a predetermined time or more. If there is an inspection input, the short phrase audio data d indicating normality of the device d “Pip is normal”, the output of the selection signal L4, followed by the long phrase audio data a indicating the monitoring area abnormality a “Woo Kang Kang Kang Fire Because the selection signal L1 of “It is a fire” is output to the speech synthesis circuit 15, the user can check the normality / abnormality of the equipment by inspection input, When the device is normal, after confirming that the device is normal, it is possible to confirm whether or not the voice message indicating the abnormality in the monitoring area is normally output by simply continuing the inspection input. . And when checking the normality / abnormality of the equipment by the inspection input by the normal switch operation, only the short phrase audio data d “pick is normal” is output at the normal time. The audio phrase can be shortened, the power supply time to the speaker 11 can be shortened accordingly, the power consumption can be reduced, and the energy saving effect can be obtained.

  In addition, when configured to output a plurality of voice messages based on the inspection input as described above, as compared to the conventional case where only the voice message indicating the monitoring area abnormality is output as the voice message indicating the normality of the device Therefore, the necessary memory capacity is increased by the amount of voice data of a voice message indicating that the device is normal. Therefore, unlike the above embodiment, the voice data of the voice message indicating the normality of the device is stored in the voice data memory 15a using a small bit rate, and only the voice data of the voice message indicating the abnormality in the monitoring area is stored. The audio data memory 15a may be stored using a large bit rate. With this configuration, the required memory capacity is increased by the amount of voice data of the voice message indicating that the device is normal, but the increase in memory can be minimized, and the existing memory capacity can be minimized. The energy saving effect by the power consumption reduction described above can be obtained.

  In addition, here, the fire detector that detects the fire by heat as the fire detection unit 5 has been described as an example using the present invention, but a fire alarm that detects a fire by other physical phenomena such as smoke and flame is described. Needless to say, the present invention can also be applied to a container.

  In addition, although the abnormality detection unit is described as an example using the present invention to the fire alarm configured with the fire detection unit 5, a gas leak alarm configured with the gas detection unit as the abnormality detection unit, It goes without saying that the present invention can also be applied to alarm devices that detect abnormalities in other events.
