Description

  TECHNICAL FIELD The present invention relates to a disaster prevention monitoring facility for performing control such as abnormality determination by voice when an abnormality such as a fire or a gas leak is detected and an alarm is issued.

  Conventionally, receivers for disaster prevention monitoring equipment that monitors fires and gas leaks are installed in disaster prevention centers and control rooms in buildings.For example, by receiving a fire signal from a fire detector or transmitter, the fire representative The main sound and the district sound device are sounded while displaying, and the interlocking control of fire doors and shutters is performed.

  For this reason, on the receiver panel, a switch for asserting a fire or gas leak to release the alarm stop or interlocking stop, a switch for stopping the main sound and district sound, a switch for recovering the receiver when there is no fire, and Is equipped with a liquid crystal touch panel and the like.

  When an alarm is output due to a fire, the disaster prevention manager and the person in charge of disaster prevention follow a sequence of predetermined handling procedures such as sound stop, site confirmation, notification to the fire department, initial fire extinguishing, evacuation guidance. You will be required to operate the switch and deal with it.

  However, in the conventional disaster prevention monitoring equipment, there is a case in which a person in charge of disaster prevention rushes due to an alarm when a fire occurs, and the receiver cannot be properly operated. Also, recent receivers can be implemented by setting various functions by programs, but due to their multi-functionality, many switches are installed on the front of the receiver, or combination operation that requires multiple switch operations, Or, it is operated by a liquid crystal touch panel, and there are many switches, and the combination operation of the switches is difficult for the operator to understand and the operation cannot be performed smoothly, so special training is required.

  In addition, an erroneous operation of the switch may hinder the people in the building from being notified of the occurrence of the fire, and the evacuation cannot be performed quickly, and at the worst, the life may be seriously affected.

  In addition, some receivers have a guidance function, such as displaying the switches that can be operated by a switch with an indicator light that has LEDs placed around the switches, etc. It is not possible to prevent malfunctions.

  By the way, in the case of pre-operated sprinkler equipment that works in conjunction with disaster prevention monitoring equipment, it has been proposed to provide a microphone in the protected area and recognize the fire definite word such as "fire" by voice to open the pre-operation valve. (Patent Document 1).

  Therefore, it is conceivable to provide a voice recognition function in the receiver for the disaster prevention monitoring equipment, recognize the voice input from the microphone provided in the receiver, and perform the control instructed by the voice.

  However, even in a disaster prevention monitoring facility that has a voice recognition function in the receiver and controls by voice input, if the receiver outputs a fire alarm, the disaster prevention personnel go to the place where the fire occurred and the fire occurs. Check if there is a fire, return to the receiver or contact by emergency telephone etc., make a fire decision by voice input at the receiver, and if there is no fire, input voice at the receiver The area sound is stopped by the above, and the cause of the sensor operation is removed at the site, and then it is restored by the voice input from the receiver.Even if the control by voice input is possible, the fire is determined, the district sound is stopped, and the restoration is restored. It takes time and effort, and it is expected that it will be difficult to respond promptly and appropriately, especially when there is only one person in charge of disaster prevention at night.

  It is also possible to install a microphone in the warning area where a fire detector is installed and send a voice signal from the microphone to the receiver to control it by voice recognition, but it is not possible to identify the place where the fire will occur in advance. There is a problem in that it is not feasible to arrange a large number of microphones and connect the signal line to the receiver because a huge number of microphones and wirings are required.

(Voice recognition effect by receiver microphone)
Further, since the voice recognition control unit provided in the receiver recognizes the voice signal input from the microphone provided in the receiver and performs the corresponding control, when the fire alarm is output from the receiver, Voice recognition is performed, for example, by inputting a voice saying "fire assertion" into the microphone provided in the receiver, and control corresponding to the fire assertion instruction is performed based on the recognition result. For example, alarm stop or transfer interlocking Automatically release the stop to enable control and response in response to a fire, save the trouble and time to search and operate the switch on the receiver, and make mistakes in operating switches and operating procedures Can be prevented.

(Effect of starting and stopping voice recognition operation)
In addition, the voice operation terminal transmits a voice input start signal by operating the voice input switch to the voice recognition control unit of the receiver, receives a confirmation response signal from the receiver, and notifies the start of voice input by sound or display. , The voice recognition control unit of the receiver, when receiving the voice input start signal from the voice operation terminal, transmits the confirmation response signal to the voice operation terminal and starts the voice recognition operation, and receives the voice signal received from the voice operation terminal. Since the voice recognition operation is stopped after recognizing and performing the corresponding control, the receiver realizes various control functions including the operation display function and the voice recognition function by the liquid crystal touch panel by executing the program by the CPU. However, by starting the voice recognition operation in the receiver by operating the switch of the voice operation terminal, it is possible to execute the voice recognition operation only at the time when the voice recognition is necessary, reducing the processing load of the receiver, The voice recognition function can be used efficiently.

  Also, the user carrying the voice operation terminal found that the voice recognition operation was started by the receiver by the output of the start sound from the voice operation terminal and the voice input became possible. It enables voice input at an appropriate timing.

(Effect of normal termination and retry of voice recognition operation)
The voice recognition control unit of the receiver transmits a normal end signal to the voice operation terminal to notify the normal end when the voice signal received from the voice operation terminal is successfully recognized and the corresponding control is performed. When the voice signal recognition fails, the retry signal is sent to the voice operation terminal to notify the re-input of the voice. It can be confirmed that the control that was instructed by the voice input was performed at the receiver at a place away from, and if the voice recognition failed at the receiver, you can know this and take measures such as re-input easily. It is possible to surely perform, and it is possible to improve the reliability of receiver control by voice input.

(Effect of control by confirmation response of voice recognition result)
In addition, the voice recognition control unit of the receiver, when the voice signal received from the voice operation terminal is successfully recognized, transmits a voice signal or a character string signal indicating the recognition result to the voice operation terminal to output the voice signal or the voice operation terminal. When a confirmation response signal is received from the terminal, the control corresponding to the recognition result is performed, so that when the receiver succeeds in recognizing the voice input, the recognition content is voice output or character string display from the voice operation terminal. If the recognition result of the voice input is correct from the contents of this notification, the confirmation switch is operated to send a confirmation response signal to the receiver, control corresponding to the recognition result is performed, and there is an error in the recognition result. In this case, erroneous control can be prevented by not receiving the confirmation response signal, and reliability of remote control by voice input can be improved.

(Effect of displaying voice input level)
In addition, since the voice control terminal is equipped with a volume indicator that displays the volume of the voice input from the microphone, it is necessary to input an appropriate amount of voice signal in order to automatically recognize the voice. Depending on the size of the volume, for example, a change in the volume is displayed by an LED bar meter, etc., and if the voice is too low, it will prompt you to approach the microphone or speak in a loud voice. Since it is possible to input the words, it is not necessary to repeatedly input the voice input many times when the voice recognition fails, and it is possible to reliably control the receiver by the voice input.

(Effect of tutorial function of voice recognition)
Further, the voice recognition control unit of the receiver recognizes the voice signal from the microphone provided in the voice operation terminal or the receiver when the voice input training mode is set, and notifies the recognition result. You can learn the best way to control by voice recognition by talking to the user, and you can understand and experience the optimum distance from the microphone and the generated sound volume. Therefore, the range that can be controlled by the automatic gain control (AGC) of the voice circuit is appropriate. It is possible to input at a sound volume, and it is possible to prevent inconvenience caused by echo or howling by inputting at a proper sound volume.

(Effect of voice operation history)
Further, the voice recognition control unit of the receiver stores the recognized voice signal or the performed control as history information when the voice signal is recognized and controlled, and the history information of the voice signal in this case is the voice signal. Since at least one of the AD-converted voice data, the coded information corresponding to the recognition result, and the text information indicating the recognition result is included, when the receiver is controlled by the voice signal from the microphone, the history information is recorded. It is saved, and if necessary, the history information by voice input can be read for analysis and confirmation.

  In addition, not only save the voice signal input from the microphone as voice data, but also store it by encoding it or converting it into text, and display or print the history information of voice input as character information. Is possible.

  Further, instead of storing history information by voice data, it is possible to reduce the storage capacity of history information and the amount of memory usage by storing it as coded information or text information indicating a character string.

(Effect of voice recognition by external device)
Further, since the voice recognition of the voice recognition control unit provided in the receiver is performed by the external voice recognition device connected via the network, for example, the advanced voice recognition function of the server existing on the Internet can be used. Thus, it is possible to obtain a highly accurate recognition result and control the receiver. Further, by eliminating the voice recognition operation by the receiver, the processing load of the receiver can be reduced.

The information output unit 104 is provided.

(Voice recognition and control)
The voice input unit 90 inputs a voice signal from the microphone 26 provided in the receiver 10, converts the voice signal into voice data by AD conversion, and receives the voice signal from the voice operation terminal 36 via the analog sensor 14 and the transmission path 12. The voice data is output to the voice recognition unit 92 as it is.

  The voice recognition unit 92 compares the input voice waveform data with the model waveform data of each character including 56 Hiragana characters stored in advance in the model storage unit 94, and converts the voice data into a Hiragana character string. In the waveform comparison by the voice recognition, the voice waveform data is converted into a predetermined multidimensional mathematical value, and the voice data is converted into a hiragana character string by a predetermined voice recognition method such as comparison and verification of multidimensional vectors.

  The control output unit 96 outputs a control signal for the receiver 10 based on the voice recognition result obtained by the voice recognition unit 92. The control output unit 96 controls the receiver based on, for example, the switch control information 106 shown in FIG. 7A and the voice recognition information 108 shown in FIG. 7B.

  The switch control information 106 of FIG. 7A is stored in the memory of the receiver control unit 16 and is composed of an address, a switch name, a control bit, a localization, and the like. In this example, at addresses 001 to 006, the assertion switch 46, the sound stop switch 48, the district sound pause switch 50, the restoration switch 52, the district sound simultaneous ringing switch 54, and the collective interlocking transfer provided at the operation unit 24 of FIG. When the stop switch 56 is registered and neither switch is operated, all the control bits are bit 0. As for the localization information, the assertion switch, the sound stop switch, the district sound stop switch, the recovery switch, and the collective interlocking transfer stop switch indicate that the stop is released, and the district sound simultaneous ringing switch is stop.

  The voice recognition information 108 of FIG. 7B is stored in the memory of the receiver control unit 16 and is composed of an address, a reference recognition voice, and a control address. The reference recognition voice includes an assert switch 46, a sound stop switch 48, a district sound stop switch 50, a recovery switch 52, a district sound simultaneous ringing switch 54, and a collective interlocking transfer stop switch 56 provided on the operation unit 24 of FIG. It stores the corresponding hiragana character string.

  For example, since the voice input corresponding to the sound stop switch 48 is assumed to be “onkyo teshi” or “keiho teshi”, this is stored in the addresses 100 and 101 as the reference recognition voice, Both control addresses store the address 001 of the sound stop switch of FIG. 7 (A).

  The control output unit 96 of FIG. 6 compares and verifies with the reference recognition voice of the voice recognition information 108 of FIG. 7 (B) when the recognition voice “onkyo teshi” is input from the voice recognition unit 92, and the matching and matched address is obtained. The control address 001 of 100 is acquired, and the control bit of the address 001 of the switch control information 106 of FIG. 7A is rewritten from the previous bit 0 to bit 1.

  The receiver control unit 16 in FIG. 1 periodically refers to the switch control information 106 in FIG. 7A, and the control bit of the sound stop switch 48 is changed to bit 1 to operate the sound stop switch 48. Is determined to have been performed, and control is performed to stop, for example, a fire sound alarm (main sound alarm) output from the receiver 10.

  This point is the same for the other reference recognition voices shown in FIG. 7 (B). For example, regarding the voice input of the assertion switch 46, “Kasadaidantei”, “GasmoneDantei”, and “Gasumoridantei”. 3 patterns of “Dandei” are stored as the reference recognition voice, and when any voice input is recognized, the control address 002 is acquired, and the control bit of the address 002 of the switch control information 106 of FIG. Will be rewritten from bit 0 to bit 1.

  Note that the method of performing control corresponding to voice input by rewriting the control bit of the switch control information 106 by the recognized voice is an example, and corresponds to the rearrangement of words, such as corresponding from the recognized voice as necessary. An appropriate method for controlling can be adopted.

(Recognized voice character string conversion)
The word conversion unit 98 of FIG. 6 refers to the correspondence between the Hiragana character string input from the voice recognition unit 92 and the Hiragana word registered in the word dictionary unit 100, and refers to the character shown in FIG. 7C. The information stored in the information buffer 110 is referred to and converted into a character string containing kanji.

  The character information buffer 102 temporarily stores the character information based on the character string containing Chinese characters converted by the word conversion unit 98, and the character information output unit 104 reads and outputs the character information. The character information output from the character information output unit 104 is displayed on the liquid crystal display unit 22 of the receiver 10 with respect to the voice input from the microphone 26 of the receiver 10 and with respect to the voice input from the voice operation terminal 36.

(1) Illumination of fire representative lights, display of fire occurrence location, output of main sound, output of district sound alarm.
(2) Confirm the location of the fire.
(3) Fire determination operation in case of fire.
(4) Call 119.
(5) District sound stop operation and restoration operation when there is no fire.

(Control by liquid crystal display unit or operation unit)
For example, if the receiver 10 receives a fire signal from a detector and outputs a fire alarm, the fire representative light provided on the display unit 20 of the receiver 10 is turned on, and the speaker of the sound alarm unit 28 outputs a predetermined main signal. An audible alarm is output, and as shown in FIG. 8A, the fire alarm screen 116 is displayed on the liquid crystal display unit 22.

  On the fire notification screen 116, a fire character 120 is displayed following a predetermined fire mark 118, and a fire occurrence location 122 is displayed under the fire character 120, and at the same time, a message 124 prompting confirmation of the fire site and an audible alarm are stopped. An operation button 126 for switching and a switching button 128 for switching to the next screen are displayed.

  Upon receiving the fire alarm of the receiver 10, the disaster prevention staff first touches the operation button 126 of the fire notification screen 116 or operates the sound stop switch 48 of the operation unit 24 shown in FIG. 3 to stop the main sound. Then, the liquid crystal display unit 22 switches to the fire alarm screen 130 of FIG. On the fire notification screen 130, "Yes" and "No" operation buttons 132 and 134 to be operated according to the site confirmation of the fire and an operation button 136 showing an overall view of the fire occurrence place are displayed on the lower side of the screen. ..

  Next, the person in charge of disaster prevention goes to the place where the fire occurred and checks the site. If there is a fire due to site confirmation, return to the receiver 10 or contact the person in charge who remains on the receiver side by an emergency call and touch the operation button 132 of the liquid crystal display 22 or see FIG. When the assertion switch 46 of the operation unit 24 is operated, the interlocking stop and the transfer stop set in the receiver 10 at that time are automatically released.

  On the other hand, if the fire is not confirmed by the site confirmation, the operation button 134 of the liquid crystal display unit 22 of FIG. 8B is touched or the district sound temporary stop switch 50 of the operation unit 24 shown in FIG. 3 is operated. The control for temporarily stopping the sound output from the district audio device is performed, and the liquid crystal display unit 22 of the receiver 10 is switched to a recovery screen provided with a recovery button.

  Therefore, by removing the cause of the operation of the sensor and touching the recovery button on the recovery screen or operating the recovery switch 52 of the operation unit 24 shown in FIG. 3, control is performed to recover the receiver 10 to the normal monitoring state. Be seen.

  The operation of the liquid crystal display unit 22 or the operation unit 24 is the same as that of the conventional receiver 10.

(Remote control by voice operation terminal)
FIG. 9 is a time chart showing a control operation by voice input performed between the voice operation terminal and the receiver through an analog sensor.

  Until the main sound is stopped when the fire alarm is output from the receiver 10, the operation is the same as before, but in the present embodiment, the disaster prevention person who goes to the fire occurrence site and confirms the site is a voice operation terminal. Carry 36.

  If there is a fire due to the site confirmation, the disaster prevention staff operates the voice input switch provided in the operation unit 84 of the voice operation terminal 36, as shown in step S1 of FIG. 9, prior to voice input. In response to this, the voice operation terminal 36 transmits a voice input start signal to the receiver 10 via the analog sensor 14 in step S2.

  Upon receiving the voice input start signal from the voice operation terminal 36, the voice recognition control unit 34 of the receiver 10 activates the voice recognition operation in step S3, and subsequently, in step S4, sends a confirmation response signal via the analog sensor 14. Then, it is transmitted to the voice operation terminal 36.

  Upon receiving the confirmation response signal from the receiver 10, the voice operation terminal 36 outputs a voice input start sound such as "beep" from the speaker 88 in step S5. When a voice is input by uttering the word "kasai dantai", the voice signal is converted into voice data by AD conversion in step S6 and transmitted to the receiver 10 via the analog sensor 14. At this time, the volume is displayed on the display unit 82 of the voice operation terminal 36 by a bar graph or the like, and by looking at the display position of the proper volume indicated on the scale of the bar graph, the voice input with the proper volume necessary for voice recognition can be performed. It will be possible.

  The receiver 10 stores the voice data transmitted by the voice operation terminal 36 in the memory in step S7, subsequently executes voice recognition in step S8, and when the success of voice recognition is determined in step S9, the voice recognition result is shown in step S10. The voice data is transmitted to the voice operation terminal 36 via the analog sensor 14.

  Upon receiving the voice data from the receiver 10, the voice operation terminal 36 outputs the voice recognition result and the confirmation response guidance by voice in step S11. The voice output of this guidance is, for example, "Fire confirmation, please press the confirmation switch if you like." The guidance may be displayed on the display unit 82 instead of the voice guidance. Further, the confirmation response may be made by voice input instead of the confirmation switch operation.

  The disaster prevention staff who receives the voice guidance operates the confirmation switch of the voice operation terminal 36 in step S12, and a confirmation response signal is transmitted to the receiver via the analog sensor 14 in step S13.

  Upon receiving the confirmation response signal from the voice operation terminal 36, the receiver 10 automatically releases the interlocking stop and the transfer stop set in the receiver 10 at that time as control based on the voice recognition result in step S14. Performs control corresponding to voice input for fire assertion. Subsequently, the receiver 10 transmits a control end signal to the voice operation terminal 36 via the analog sensor 14 in step S15, and the voice operation terminal 36 which has received the signal indicates the normal end of control by voice input in step S16. Notify by display or voice output.

  On the other hand, when the receiver 10 determines in step S9 that the voice recognition has failed, the receiver 10 transmits a retry signal to the voice operation terminal 36 to notify the re-input of the operation voice.

  By voice input using such a voice operation terminal 36, the disaster prevention staff heading to the site for confirming the place where the fire occurred confirms the time and effort of contacting the receiver side and returning to the receiver to perform necessary operations. Since it can be omitted and it is not necessary to return to the receiver, it is possible to immediately take measures such as initial fire extinguishing and evacuation guidance at the fire site.

(Control by voice input of receiver)

It has a so-called tutorial function to display.

  The display of the recognition result of recognizing the voice signal from the microphone 26 is not limited to the display of the character string. For example, appropriate notification such as display by symbols such as “OK” or “NG”, display by LED display color or pattern such as blinking, output by buzzer sound or speaker sound, screen display by pictogram or figure of control content, etc. included.

  With such a voice recognition tutorial function, it is possible to talk to the receiver 10 to learn the optimum method for performing control by voice recognition, and to understand and experience the optimum distance from the microphone and the generated sound volume. It is possible to input at an appropriate volume within a range that can be controlled by automatic gain control (AGC), and it is possible to prevent inconvenience due to echo or howling by inputting at an appropriate volume.

(Effect of voice operation history)
Further, the voice recognition control unit 34 of the receiver 10 has a history storage function of storing the recognized voice signal or the performed control as history information in the memory when the voice signal by voice input is recognized and controlled. The history information of the voice signal input by voice and stored in the receiver 10 is at least one of voice data obtained by AD converting the voice signal, coded information corresponding to the recognition result, and text information indicating the recognition result. In this case, the voice signal input from the microphone is coded or converted into text and saved, so that the storage capacity of history information can be reduced and memory usage can be reduced compared to the case of saving voice data. ..

(Voice recognition function by external device)
Alternatively, the voice recognition of the voice recognition control unit 34 provided in the receiver 10 may be performed by a voice recognition engine provided in an external server or the like connected via a network such as the Internet. By using the advanced speech recognition engine of the server existing on the Internet in this way, it is possible to obtain a highly accurate recognition result and control the receiver 10 by voice input. By eliminating the recognition operation, the processing load of the receiver 10 can be reduced.
