Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an evacuation guidance device that provides evacuation guidance through audio broadcasting when an emergency situation such as a fire or an earthquake occurs.

(Prior art) Conventionally, when an emergency situation such as a fire or an earthquake occurs, evacuation guidance is generally broadcast using an emergency broadcast system, and guidance lights installed in hallways etc. are used to provide evacuation guidance. Make sure to check the evacuation direction and evacuate through emergency exits, etc.

(Problem to be solved by the invention) However, in conventional evacuation guidance announcement broadcasts, the location and situation of the fire and simple comments urging evacuation are announced for the whole area or for each area divided into blocks. However, in actual evacuation, people were supposed to evacuate according to the signs installed in the area, such as guide lights, so in the announcement broadcast, the evacuation direction for each area was not sufficiently clear because the situation in the broadcast area was difficult to understand. As the situation is left to the discretion of the evacuees, there is a possibility that they will evacuate in the direction of the fire by mistake, and furthermore, if they are unable to check the guide lights due to smoke, it may cause great confusion. was there.

Therefore, instead of using an anallancer broadcast for evacuation guidance by an operator, evacuation guidance broadcasts for each broadcasting area according to the occurrence of emergency situations such as fires and earthquakes are pre-recorded on recording media such as tapes and memory. It is also conceivable to select the corresponding broadcast content according to the occurrence of the fire, and broadcast evacuation guidance in order from the area closest to the place where the fire or the like occurred, for example.

However, because it was not possible to simultaneously broadcast different content to multiple districts from the central equipment, it took time to broadcast evacuation guidance to all districts, and situations occurred where the broadcast content had to be changed midway through. In some cases, large delays may occur in evacuation guidance.

In addition, if the broadcasting line is disconnected midway due to fire, etc.,
There was also the problem of not being able to broadcast.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems in the prior art. To provide an evacuation guidance device capable of giving appropriate evacuation guidance instructions by simultaneously broadcasting evacuation guidance with different contents to all areas divided into blocks.

In order to achieve this object, the present invention connects a plurality of terminal devices that also have a data transmission function to a center device that has a data transmission function via a signal line, and broadcasts information on evacuation guidance broadcasts from the center device. In an evacuation guidance device that broadcasts evacuation guidance on each terminal device based on A combination of code numbers giving the contents of the evacuation guidance broadcast is created for each terminal based on the above and transmitted sequentially.On the other hand, the terminal equipment transmits the audio data of the audio word corresponding to the audio code number of the center equipment. A memory is prepared in advance to store the
Evacuation guidance broadcasting is performed by sequentially reading the audio data of audio words stored in the memory and synthesizing the audio data according to the combination code number giving the broadcast content transmitted from the center device.

(Example) FIG. 3 is an explanatory diagram showing the overall configuration of the present invention.

In Figure 3, 1 is the center device, which is used for fire, earthquake, etc.
A combination of audio word code numbers giving the content of evacuation guidance broadcasts for each terminal area divided into blocks based on emergency information such as gas leaks is created and transmitted sequentially to each terminal. Terminal devices 3a, 3b, ... 3n are connected to the signal line 2 drawn out from the center device 1 for each area, and the terminal devices 3
A to 3n receive broadcast information for carrying out an evacuation guidance device that is sequentially transmitted from the center device 1, and the speakers 4a to 4
evacuation guidance broadcasts are being made to the area under jurisdiction. Here, as the signal line 2, in addition to the dedicated signal line, C
A coaxial cable of an ATV system, a broadcast signal line for announcement broadcasting, or a detector line of a fire alarm system can be used.

FIG. 1 shows a specific embodiment of the center device 1 shown in FIG. 3, and takes as an example the control of evacuation guidance broadcasts based on fire signals as emergency information.

In FIG. 1, reference numeral 5 denotes a fire area storage unit, which inputs and stores a fire signal indicating the area where the fire occurred from a receiver of a fire alarm system (not shown). Reference numeral 6 denotes an evacuation guidance information storage section, in which guidance patterns such as evacuation guidance directions for each terminal area where evacuation guidance broadcasts are to be made according to the area where the fire occurred are stored in advance. Furthermore, 7 is an audio code number storage unit which stores audio code numbers representing audio words used in the text structure of evacuation guidance broadcasts, as shown in FIG. It is possible to create audio output sentences for evacuation guidance broadcasts.

15 is an audio information transmission section, a broadcast content editing and creation section 8;
It includes a terminal transmission data storage section 9 and a transmission control section 10.

First, the broadcast content editing and creation unit 8 determines a guidance pattern such as a guidance direction in the evacuation guidance information storage unit 6 for each terminal area based on the fire occurrence area stored in the fire area storage unit 5. The text of the evacuation guidance broadcast corresponding to the guidance pattern is created as a combination of code numbers corresponding to the audio words in the audio code number storage section 7, and the combined code number for each terminal is stored in the terminal transmission data storage section 9. The transmission control unit 10 is connected to the signal line 2 via a modem (modem/demodulation device) 11, and sequentially reads combination code numbers representing the contents of evacuation guidance broadcasts for each terminal stored in the terminal transmission data storage unit 9, It is sent to the signal line 2 by the modem 11 with a transmission frame structure of .

Here, the frame structure of the transmission information to the terminal by the transmission control unit 10 is composed of an address, a command, data, and a frame check, as shown in FIG. Data numbers 1 to 16 shown in FIG. 6 are taken for the area, and are, for example, terminal transmission data.

- If the combination code number having the broadcast content as shown in FIG. 5 is stored in the evening storage section 9, the corresponding bit of the data number of the transmission data code shown in FIG.
'', and the others are rOJ, and data is transmitted to the terminal side with the frame structure shown in FIG.

Furthermore, in order to confirm data reception on the terminal side, the transmission control unit 10 inputs response data sent back from the modem 11 when data is received on the terminal side and outputs it to the transmission control unit 10 for confirmation. A terminal response confirmation section 12 is provided which generates a terminal response confirmation section 12, and when a transmission terminal confirmation output is obtained from the terminal response confirmation section 12 when transmitting a combination code number for each terminal, the transmission control section 10 transmits data to the next terminal, If no confirmation output is obtained, the same combination code number is repeatedly transmitted.

Furthermore, after transmitting the combination code number to the terminal, the transmission control unit 10 sends an audio transmission command for starting the evacuation guidance broadcast on the terminal side and a termination command for ending the evacuation guidance broadcast on the terminal side. As shown in FIG. 9, the frame structure of the audio sending command and ending command is such that data for the audio sending command or ending command is placed in a command area consisting of an address, a command, and a frame check, and then sent.

Furthermore, common address information that enables data reception at all terminals is used as the address used in the frame structure of the audio sending command and termination command shown in FIG. For this reason,
On the terminal side, address information unique to each terminal and common address information are set as its own address.

FIG. 2 is a block diagram showing a specific embodiment of the terminal device shown in FIG. 3.

In FIG. 2, the terminal device 3 is connected to the signal line 2 from the center device via the modem 20, and gives the received data demodulated by the modem 20 to the address discriminator 21, and transmits the set address of itself or all terminals. When any of the common addresses for the command is determined, a determination output is generated in the command determination section 22. The command discriminator 22 decodes the contents of the command following the address and produces different determination outputs depending on the decoded contents. The determination output of this command determination unit 22 is as follows:
These are commands representing the combination number code in the transmission frame structure of FIG. 7, and commands representing the audio transmission command or termination command shown in FIG. 9. When the command representing the audio code number is decoded, the combination code number is decoded and stored. A discrimination output is generated in the unit 24, and the data following the command, ie, the data bits representing the combination of audio data numbers shown in FIG. 6, are decoded and stored. Further, if it is a voice sending command, a determination output is generated to the start circuit 26, and if it is an end command, a determination output is generated to the stop circuit 27.

Reference numeral 25 denotes an audio word storage unit, which stores audio words necessary for the text structure of evacuation guidance broadcasts in the form of digital audio data, specifically audio code numbers 1 to 11 as shown in FIG. ``Fire'', ``Emergency'', ``Earthquake'' in response to
The voice words necessary for the sentence structure of voice-guided broadcasts such as ``Voice-guided Broadcasting'' are stored in the form of digital voice data.

Reference numeral 28 denotes a broadcast content editing and creation section, which sequentially reads digital audio data of corresponding audio words from the audio word storage section 25 according to the combination code number sent from the center device stored in the combination code number decoding storage section 24, Digital audio data according to a series of combination code numbers is stored in a memory or the like. Reference numeral 29 denotes a speech synthesis circuit, which operates based on the startup output of the startup circuit 26 and converts a series of audio digital data created based on the combination code number from the center device in the audio content editing and creation section 28 into an analog audio signal. The signal is converted and amplified by the audio amplifier 30, and an evacuation guidance broadcast is performed from the speaker 4. The evacuation guidance broadcast by the voice synthesis circuit 29 is repeatedly broadcast until a stop output from the stop circuit 27 is obtained.

Further, a determination output when the command content is decoded by the command determination unit 22 is given to the confirmation data transmission unit 23, which transmits confirmation data to the center device via the modem 20 based on the decoding of the command content. I am doing this,
This confirmation data has a frame structure including address, data, and frame check as shown in FIG. 8, for example.

Next, the operation of the above embodiment will be explained with reference to the flowchart of FIG. 10.11.

First of all, FIG. 10 is a flowchart showing the control operation of the center device. In block 32, the presence or absence of a fire is monitored. When a fire signal is obtained, the process proceeds to block 34, and each evacuation direction is determined based on the area where the fire occurred. Determine evacuation guidance patterns such as Next, in block 36, a combination code number is created to give the content of the evacuation guidance broadcast for each terminal based on the determined evacuation direction, etc., and in block 38, a combination code number is created for each terminal to give the content of the evacuation guidance broadcast as shown in FIG. 7. A frame code for the data is created and data transmission to the terminal begins at block 40. When data is transmitted to the first terminal in block 40, it is monitored in decision block 42 whether or not an acknowledgment of data reception is obtained from the terminal.If confirmation is not obtained, the process returns to block 40 and the same terminal is transferred Transmit data. When confirmation from the terminal is obtained in decision block 42, it is checked in decision block 44 whether or not it is the final terminal, and the process returns to block 40 again to transmit data to the next terminal, and this data transmission is repeated until the final terminal.

When data transmission to all terminals is completed, block 46
Then, a voice transmission command is transmitted to all terminals, and the terminals perform evacuation guidance broadcasts.

Next, a judgment block 48 checks whether there is a change in the evacuation direction, and if a new fire signal is obtained due to the progress of the fire, it is determined that the evacuation direction has changed and the process returns to the judgment block 32 and a new evacuation direction is detected. Creates combination code numbers for evacuation guidance broadcasts based on fire signals and processes transmission to terminals. If there is no change in the direction of evacuation guidance, a judgment block 50 monitors whether a command to end broadcasting has been issued, and the command to end broadcasting is issued by switch operation by the operator of the center device or by the disappearance of the fire signal. Then, in block 52, a broadcast termination command is transmitted to all terminals, and the series of processing is completed.

In this way, the transmission of voice information for the evacuation guidance device from the center device to the terminal device is only the transmission of a combination code number consisting of a combination of code numbers of voice words representing the broadcast content, and the digital voice corresponding to the voice word is transmitted. Since no data is transmitted, the time required to transmit voice information from the center device to the terminal device is extremely short.

FIG. 11 is a flowchart showing an example of the operation of the terminal device. In the normal monitoring state, the terminal device monitors at a determination block 62 whether or not data is received from the center device. When the data from the center device is received, the process proceeds to a determination block 64, where it is determined whether or not it is the own address. When the self address is determined, the process proceeds to block 66, where the command following the address is decoded. Here, the content of the command is either a combination code number transmission command, an audio output command, or an end command.Since the command is initially a combination code number command, the process advances to block 70, and the combination code number is input from the data area following the command. decipher and memorize. Next, in block 72, confirmation data is sent to the center device, and in block 74, based on the decoded combination code number, the digital audio signals of the audio words stored in the terminal side are sequentially read out and the contents of the evacuation guidance broadcast are read out. create a series of digital audio data representing the

In this way, after the editing of the audio broadcast message is completed in block 70, the center device issues an audio transmission command.

Since the command is sent, the command is decoded in the determination block 68 and the voice transmission command is determined, and then the determination block 7
6, and since this is a command to start audio broadcasting, the process goes to block 78, where an emergency broadcast for evacuation guidance is made.
The digital audio data edited in block 74 is converted into an analog audio signal by audio synthesis, and evacuation guidance is broadcast from a speaker. This evacuation guidance broadcast is repeated until a command to end the broadcast is given from the center device, and when the command for the end of broadcast command is determined, the process proceeds to block 80 and the evacuation guidance broadcast is stopped.

(Effects of the Invention) As described above, according to the present invention, a plurality of terminal devices also having a data transmission function are connected to a center device having a data transmission function via a signal line, and evacuation from the center device is possible. In an evacuation guidance device that broadcasts evacuation guidance on each terminal device based on the guidance broadcast information, each terminal device stores in advance the audio data of the voice words necessary for the sentence structure of the evacuation guidance broadcast in correspondence with the code number. Leave it alone, fire.

When emergency information such as an earthquake or gas leak is obtained, a combination code number consisting of a combination of code numbers that creates the content of evacuation guidance broadcasts is transmitted from the center device to each terminal device, and the terminals are activated based on this combination code number. Since the device side sequentially reads the audio data of the audio words stored in advance and performs the evacuation guidance broadcast by voice synthesis,
In the event of an emergency such as a fire, evacuation guidance broadcasts can be made individually for each block-divided broadcasting area based on the determination of evacuation guidance patterns in the center equipment, making it possible to make evacuation guidance broadcasts individually for each block-divided broadcasting area. Evacuation guidance broadcasting can be more detailed than evacuation guidance, and prompt and appropriate evacuation actions can be taken in accordance with the contents of the evacuation guidance broadcast.

In addition, since the center device only needs to transmit the voice word combination code number to the terminals, the transmission time to all terminals is extremely short, and in the event of an emergency such as a fire, all terminals can be It is possible to broadcast evacuation guidance specific to each terminal area at the same time, and even if the evacuation guidance direction changes due to the spread of a fire etc. after broadcasting has started, the transition to a new evacuation guidance broadcast can be made in almost real time for all broadcast areas. It can be done all at once.

In addition, even if the transmission line etc. is disconnected due to a fire, the broadcast content will be remembered as long as the power of the terminal does not go down.
You can continue broadcasting.
