  However, a radio channel that is being used by one command board cannot be used by another command board. For this reason, the operator of the command stand that has received an emergency call waits for the end of communication of the command stand or forcibly sets the radio channel in use when another command stand sends a command to an emergency vehicle in communication. However, there is a problem that it takes time until a simultaneous command is issued to all necessary emergency vehicles. This problem exists not only in the fire fighting command system but also in other communication command systems.

  Therefore, the present invention has been made in view of the above-described problems, and an object thereof is to provide a communication command system, a communication command device, and a communication command method capable of promptly issuing a simultaneous command.

  The communication command system described in this specification selects a radio channel having a plurality of radio channels for communicating with a mobile station, an unused radio channel from the plurality of radio channels, and is currently selecting the radio channel Mobile station and a plurality of communication command devices that communicate with each other via the wireless communication device, and among the plurality of communication command devices, a communication command device that has received an emergency call is configured to transmit the plurality of wireless channels. Among them, an unused radio channel is selected, and a command is transmitted to the mobile station that is selecting the radio channel, and other communication command devices that are in communication superimpose the command on the communication of the selected radio channel.

  The communication instruction device described in the present specification includes an unused radio channel from a plurality of radio channels for communicating with a mobile station, the mobile station currently selecting the radio channel, and the plurality of radio channels. In a communication command device that communicates via a wireless communication device, when an emergency call is received, an unused wireless channel is selected from the plurality of wireless channels, and a command is transmitted to the mobile station that is selecting the wireless channel And a transfer processing unit for transferring the command to another communication commanding device, wherein the transmitting unit determines a radio channel in use from the plurality of radio channels and selects the radio channel. Are instructed to superimpose the command transferred by the transfer processing unit on the communication of the wireless channel.

  FIG. 1 shows the operation of the wireless communication system in the comparative example. As an example, the wireless communication system is used for communication between in-vehicle wireless devices of a plurality of emergency vehicles 8 such as fire trucks and ambulances and a communication command system installed in the fire department headquarters. The communication command system includes a plurality of command tables (# 1, # 2) 1 and a wireless communication device 2. The emergency vehicle 8 is an example of a mobile station for wireless communication, and the command board 1 is an example of a communication command device.

  A plurality of base stations 9 and a wireless communication device 2 of a communication command system are connected to the wireless communication network NW. The wireless communication device 2 includes a plurality of wireless channels CH1 to CH3 for communicating with a mobile station. The radio channels CH1 to CH3 use different frequencies, and each command board 1 can communicate with the emergency vehicle 8 using the selected radio channel.

  Moreover, the vehicle-mounted radio | wireless machine of each emergency vehicle 8 communicates with the command stand 1 via the selected radio channel. In this example, the radio channel CH1 is selected for the in-vehicle radio of the emergency vehicle (# 1, # 2) 8, and the radio channel CH2 is selected for the in-vehicle radio of the emergency vehicle (# 3- # 6) 8, and the emergency vehicle (# 7, # 8) In the in-vehicle wireless device of 8, the wireless channel CH3 is selected.

  For example, when the command board (# 1) 1 selects the radio channel CH1 (see “CH1”), the emergency vehicles (# 1, # 2) 8 that are selecting the same radio channel CH1 and the radio communication device 2 (see “in communication”).

  However, the radio channel being used by the command board (# 1) 1 cannot be used by the other command board (# 2) 1. For this reason, the command board (# 2) 1 selects the unused radio channels CH2 and CH3 ("CH2, 3") when it is necessary to send an instruction to all emergency vehicles 8 in response to an emergency call. Even if the command can be transmitted to some emergency vehicles (# 3 to # 8) 8, the command cannot be transmitted to the emergency vehicle (# 1, # 2) 8 that is selecting the radio channel CH1 ("NG" "reference).

  Therefore, the command board (# 2) 1 needs to wait for the communication of the command board (# 1) 1 to end or forcibly release the radio channel CH1 being used. It takes time to do.

  Therefore, in the communication command system of the embodiment, as described below, the command table (# 2) that has received an emergency call for communication of the radio channel CH1 being used by the command table (# 1) 1 among the radio channels. By superimposing a command transmitted from 1 to the emergency vehicle 8, a simultaneous command is quickly transmitted to the emergency vehicle 8.

  FIG. 2 shows the operation of the wireless communication system in the embodiment. In FIG. 2, the same reference numerals are given to configurations common to FIG. 1, and the description thereof is omitted.

  The command voice of the command board (# 2) 1 is mixed with the voice of communication of the command board (# 1) 1 in the command board (# 1) 1 during communication (see “Mixing”). Since the mixed voice is transmitted to the emergency vehicle (# 1, # 2) 8 via the radio channel CH1, the emergency vehicle (# 1, # 2) 8 receives the command from the command board (# 2) 1. Yes (see “OK”).

  In this way, the command board (# 2) 1 that has received the emergency call selects the unused radio channels CH2 and CH3, and instructs the emergency vehicle (# 3 to # 8) 8 that is selecting the radio channel. The other command base (# 1) 1 that transmits and superimposes the command of the command base (# 2) 1 on the communication of the selected radio channel CH1.

  For this reason, the command stand (# 2) 1 does not wait for the end of the communication of the command stand (# 1) 1 or forcibly releases the radio channel CH1 in use, and sends it to all emergency vehicles 8. Simultaneous command can be sent. Therefore, in the communication command system of the embodiment, the simultaneous command can be quickly transmitted to all the emergency vehicles 8. The configuration of the communication command system will be described below.

  FIG. 3 is a configuration diagram illustrating an example of a communication command system. The communication command system includes a plurality of command tables (# 1 to # 4) 1, a radio communication device 2, a common input / output device 3, and an exchange 4.

  The exchange 4 is connected to a terminal 7 such as a telephone via a public telephone network 70. The exchange 4 is connected to the wireless communication device 2 and a plurality of command boards 1 via a LAN (Local Area Network) or the like. When an emergency call is received from the terminal 7, the exchange 4 is connected to the command board 1 that is not communicating. Connect the emergency call line. Thereby, the command board 1 and the reporter's terminal 7 are connected, and the first report of a disaster such as a fire is notified to the operator of the command board 1.

  Upon receiving the emergency call, the command board 1 organizes the emergency vehicle 8 according to the scale of the disaster and requests the fire station to dispatch the emergency vehicle 8. The command from the command board 1 to the emergency vehicle 8 is transmitted via the wireless communication device 2 as described above.

  The wireless communication device 2 is connected to the base station 9 via the wireless communication network NW. The base station 9 and the in-vehicle wireless device 80 of the emergency vehicle 8 are connected via a wireless channel line selected by the in-vehicle wireless device 80. The command stand 1 selects an unused radio channel and transmits a command to the emergency vehicle 8 that is selecting the same radio channel.

  The common input / output device 3 is an example of a distribution device, and distributes communication from each command board 1 to the emergency vehicle 8 to all other command boards 1. For example, the voice transmitted from the command board (# 1) 1 to the emergency vehicle 8 is distributed to the command boards (# 2 to # 4) 1. For this reason, each command board 1 can acquire communication and command voices transmitted from other command boards 1. The configuration of the command board 1 will be described below.

  FIG. 4 is a configuration diagram illustrating an example of a command board. The command stand 1 includes a control unit 10, a touch panel 11, a stand input / output device 12, and a microphone device 13. The control part 10 is comprised by at least 1 CPU (Central Processing Unit), for example, and performs the communication process of the command stand 1. FIG.

  The control unit 10 displays an operation screen on the touch panel 11 and performs communication processing according to an operation of the operator on the operation screen. The control unit 10 refers to the channel (CH) management table 20 of the wireless communication device 2 to determine the usage status of the wireless channel.

  The channel management table 20 indicates a vacancy (see “empty”) for each channel (see “CH”) (“◯”: empty, “×”: in use). In the example of FIG. 4, the radio channel CH1 is in use, and the radio channels CH2 and CH3 are empty, that is, unused.

  Based on the channel management table 20, the control unit 10 discriminates the used or unused radio channels CH1 to CH3. The control unit 10 is an example of a transmission unit. When an emergency call is received, the control unit 10 selects unused radio channels CH2 and CH3 and transmits a command to the emergency vehicle 8 that is selecting the radio channels CH2 and CH3.

  FIG. 5 shows an example of the operation screen of the touch panel 11. For example, a CH1 button 110, a CH2 button 111, a CH3 button 112, and a command start button 113 are displayed on the operation screen.

  The CH1 button 110, the CH2 button 111, and the CH3 button 112 display the availability of the wireless channels CH1 to CH3 based on the information in the channel management table 20, respectively. For example, when the CH1 button 110, the CH2 button 111, and the CH3 button 112 are white, it indicates that the radio channels CH1 to CH3 are not used, respectively, and when yellow, the radio channels CH1 to CH3 are the other command boards 1. Indicates that it is in use. Further, when the CH1 button 110, the CH2 button 111, and the CH3 button 112 are red, it indicates that the radio channels CH1 to CH3 are being used in the command board 1 of the own.

  The command start button 113 is pressed when starting a command to the emergency vehicle 8. At this time, the CH1 button 110, the CH2 button 111, and the CH3 button 112 are used to select the radio channels CH1 to CH3 that transmit the command. As described above, a command is transmitted by superimposing a command on the communication of the command table 1 for a wireless channel being used by another command table 1.

  Referring back to FIG. 4, the microphone device 13 collects the voice of the operator of the command board 1 and outputs it to the board input / output device 12. The stand input / output device 12 outputs the sound input from the microphone device 13 to the common input / output device 3. As described above, the common input / output device 3 outputs the sound input from one command board 1 to all the other command boards 1. That is, the table input / output device 12 is an example of a transfer processing unit, and transfers the command transmitted from the control unit 10 to the other command table 1.

  Also, the stand input / output device 12 mixes the audio selected from the audio input from the microphone device 13 and the common input / output device 3 according to the selection signal input from the control unit 10 and outputs the mixed audio to the control unit 10. To do. Using the radio channel selected when the command start button 113 is pressed, the control unit 10 transmits a sound of the microphone device 13 or a sound obtained by mixing a sound of a command from another command board 1 with the sound.

  Further, the control unit 10 transmits a command transmission instruction to the other command board 1 via the LAN based on the radio channel selected when the command start button 113 is pressed (see dotted line). In other words, the control unit 10 discriminates the radio channel in use and superimposes the command transferred by the base input / output device 12 on the communication of the radio channel with respect to the other command base 1 that is selecting the radio channel. To instruct.

  When the control unit 10 receives a command transmission instruction from another command table 1, the control unit 10 outputs a selection signal to the table input / output device 12 so that the sound of the command table 1 is selected. Thereby, the voice of the command of the other command board 1 is mixed with the voice of the microphone device 13.

  In this way, the command stand 1 in communication acquires the command of the other command stand 1 from the communication distributed from the common input / output device 3 from the microphone device 13, and superimposes it on the communication of the selected radio channel. For this reason, the command stand 1 in communication can be superimposed on the communication by any other command stand 1 command. The mixing operation will be described below.

  FIG. 6 shows an example of the mixing operation. The common input / output device 3 is provided with terminals (# 1, # 2,...) 30 corresponding to the command boards 1. The terminals 30 are connected to each other, and audio signals are input / output. The stand input / output device 12 of each command stand 1 is connected to a terminal 30 corresponding to the command stand 1.

  The stand input / output device 12 is provided with a mixer 120 for mixing different sounds and terminals (# 1, # 2,...) 121 corresponding to the command stands 1. The audio signal from the microphone device 13 is input to the terminal 121 corresponding to the own device, and is output to the mixer 120 and the terminal 30 of the common input / output device 3.

  For example, in the command board (# 1) 1, the audio signal VC # 1 from the microphone device 13 is input to the mixer 120 and the terminal (# 1) 30 of the common input / output device 3 via the terminal (# 1) 121. The The audio signal VC # 1 is sent from the terminal (# 1) 30 through the other terminals (# 2, # 3,...) 30 to the terminal (# 1) 30 of the common input / output device 3 of the other command board 1. Is input.

  In the command board (# 2) 1, the audio signal VC # 2 from the microphone device 13 is input to the mixer 120 and the terminal (# 2) 30 of the common input / output device 3 via the terminal (# 2) 121. The The audio signal VC # 2 is sent from the terminal (# 2) 30 through the other terminals (# 1, # 3,...) 30 to the terminal (# 2) 30 of the common input / output device 3 of the other command board 1. Is input.

  Further, the mixer 120 mixes the audio signal VC of the terminal 121 selected based on the selection signal SEL from the control unit 10 and outputs it to the control unit 10. In this example, based on the example of FIG. 2, among the terminals 121 of the command board 1, the selected terminal 121 is displayed with a solid line, and the non-selected terminal 121 is displayed with a dotted line.

  In command board (# 2) 1, control unit 10 outputs selection signal SEL # 2 for selecting terminal (# 2) 121 to mixer 120. The mixer 120 outputs the audio signal VC # 2 at the terminal (# 2) 121, that is, the audio signal VC # 2 from the microphone device 13 to the control unit 10.

  In this case, the mixer 120 does not perform mixing because there is only one selected audio signal. The control unit 10 transmits the audio signal VC # 2 input from the mixer 120 to the emergency vehicle (# 3 to # 8) 8 that is using the same radio channel CH2 and CH3 via the radio channel CH2 and CH3. To do.

  On the other hand, in the command board (# 1) 1, the control unit 10 outputs a selection signal SEL # 1 for selecting the terminal (# 1) 121 to the mixer 120. Further, the control unit 10 follows a command transmission instruction from the command board (# 2) 1 that has received an emergency call, and receives a command audio signal VC # 2 from the command board (# 2) 1 (# 2). ) The selection signal SEL # 2 for selecting 121 is output to the mixer 120.

  The mixer 120 mixes the audio signal VC # 2 at the terminal (# 2) 121 and the audio signal VC # 1 at the terminal (# 1) 121 and outputs the mixed signal to the control unit 10. The control unit 10 transmits the audio signals VC # 1 and VC # 2 input from the mixer 120 to the emergency vehicle (# 1, # 2) that is using the same radio channel CH1 via the selected radio channel CH1. 8 to send.

  In this way, the command base (# 2) 1 during communication mixes the voice of the command of the other command base (# 1) 1 with the voice input to its own device, so that the selected radio channel CH1 is selected. Superimpose commands on communication. Therefore, the command voice can be easily transmitted via the radio channel CH1 that is selected by the other command board 1.

  FIG. 7 is a sequence diagram illustrating an example of the operation of the communication command. FIG. 7 shows communication between apparatuses based on the example of FIG.

  The control unit 10 of the command board (# 1) 1 transmits a channel (CH) selection signal to the radio communication device 2 in order to select the radio channel CH1. The wireless communication device 2 transmits a selection response signal to the control unit 10 in order to allow the command base (# 1) 1 to use the wireless channel CH1.

  Next, the control unit 10 of the command board (# 1) 1 transmits a selection signal SEL # 1 to the board input / output device 12 in order to select the terminal (# 1) 121. As a result, the audio signal VC # 1 is output from the terminal (# 1) 121 of the table input / output device 12 to the control unit 10. The control unit 10 transmits the audio signal VC # 1 to the in-vehicle wireless device 80 of the emergency vehicle 8 that is selecting the wireless channel CH1 via the wireless communication device 2.

  Next, the wireless communication device 2 notifies the control unit 10 of each command board 1 of the channel (CH) state based on the channel management table 20. When command board (# 2) 1 receives the emergency call, it determines unused radio channels CH2 and CH3 based on the channel state. The command board (# 2) 1 transmits a channel selection signal to the radio communication device 2 in order to select the radio channels CH2 and CH3. The wireless communication device 2 transmits a selection response signal to the control unit 10 in order to allow the command base (# 2) 1 to use the wireless channels CH2 and CH3.

  Next, the control unit 10 of the command board (# 2) 1 transmits a selection signal SEL # 2 to the board input / output device 12 in order to select the terminal (# 2) 121. As a result, the audio signal VC # 2 is output from the terminal (# 2) 121 of the table input / output device 12 to the control unit 10. The control unit 10 transmits the audio signal VC # 2 to the in-vehicle wireless device 80 of the emergency vehicle 8 that is selecting the wireless channels CH2 and CH3 via the wireless communication device 2.

  In addition, the control unit 10 of the command board (# 2) 1 superimposes the command voice signal VC # 2 on the communication of the command board (# 1) 1 that is selecting the radio channel CH1, so that a command transmission instruction is issued. (# 1) Transmit to 1 control unit 10. Since the control unit 10 of the command board (# 1) 1 selects the terminal (# 1) 121 and the terminal (# 2) 121 in accordance with the command transmission instruction, the selection signal SEL # 1 / # 2 is sent to the machine input / output device 12. Send.

  As a result, the command input / output device 12 of the command board (# 1) 1 receives not only the voice signal VC # 1 from the microphone device 13 but also the voice of the command from the command board (# 2) 1 that received the emergency call. Signal VC # 2 is also input. The stand input / output device 12 mixes the two audio signals VC # 1 and VC # 2 by the mixer 120 and outputs them to the control unit 10. The control unit 10 transmits the mixed audio signals VC # 1 and VC # 2 to the in-vehicle wireless device 80 of the emergency vehicle 8 that is selecting the wireless channel CH1 via the wireless communication device 2.

  In this way, the simultaneous command is promptly transmitted to all the emergency vehicles 8 from the command stand (# 2) 1 that has received the emergency call.

  FIG. 8 is a flowchart showing an example of the operation of the command board (# 2) 1 that has received an emergency call. The command board (# 2) 1 determines whether or not there is an emergency call (step St1). Command board (# 2) 1 ends the operation when there is no emergency call (No in step St1).

  When the command board (# 2) 1 receives an emergency call (Yes in step St1), the command board (# 2) 1 selects unused radio channels CH2 and CH3 based on the channel management table 20 (step St2). Next, the command board (# 2) 1 determines whether or not there is a wireless channel in use (step St3). When there is a radio channel in use (Yes in step St3), the command board (# 2) 1 transmits a command transmission instruction to the command board (# 1) 1 in use of the radio channel (step St4). In addition, when there is no wireless channel in use (No in Step St3), the command board (# 2) 1 performs the following operation in Step St5 without transmitting a command transmission instruction.

  Next, the command board (# 2) 1 outputs the command audio signal VC # 2 input from the microphone device 13 (step St5). The output audio signal VC # 2 is transmitted to the emergency vehicle 8 of the radio channels CH2 and CH3 via the radio communication device 2, and the command board (# 1) 1 in communication via the common input / output device 3 Sent to. In this way, the command board (# 2) 1 that has received the emergency call operates.

  FIG. 9 is a flowchart showing an example of the operation of the command board (# 1) 1 that has received a command transmission instruction. The command board (# 1) 1 determines whether or not a command transmission instruction has been received from another command board 1 (step St21).

  When there is no command transmission instruction (No in step St21), the command board (# 1) 1 outputs the audio signal VC # 1 from the microphone device 13 (step St24). The output audio signal VC # 1 is transmitted to the emergency vehicle 8 of the radio channel CH1 via the radio communication device 2.

  When the command board (# 1) 1 receives a command transmission instruction (Yes in step St21), the voice signal VC # 1 from the microphone device 13 and the voice signal VC # 2 from the command board (# 2) 1 Is mixed by the mixer 120 (step St22). Next, the command board (# 2) 1 outputs the mixed audio signals VC # 1 and VC # 2 (step St23).

  The mixed audio signals VC # 1 and VC # 2 are transmitted to the emergency vehicle 8 of the radio channel CH1 via the radio communication device 2. Therefore, the command stand (# 2) 1 that has received the emergency call can transmit the command to the emergency vehicle 8 using the radio channel CH1 that is selected by the other command stand (# 1) 1. In this way, the command board (# 1) 1 that has received the command transmission instruction operates.

  As described above, the communication command system according to the embodiment includes the wireless communication device 2 and the plurality of command tables (# 1, # 2) 1. The wireless communication device 2 includes a plurality of wireless channels CH1 to CH3 for communicating with the emergency vehicle 8. The plurality of command boards (# 1, # 2) 1 selects an unused radio channel from the plurality of radio channels CH1 to CH3, and the emergency vehicle 8 that is selecting the radio channel and the radio communication device 2 Communicate with each other.

  Upon receiving the emergency call, the command board (# 2) 1 selects the unused radio channels CH2 and CH3, transmits a command to the mobile station that is selecting the radio channel, and sends another command board (# 1) 1 superimposes the command of the command board (# 2) 1 on the communication of the currently selected radio channel CH1.

  For this reason, the command stand (# 2) 1 does not wait for the end of the communication of the command stand (# 1) 1 or forcibly releases the radio channel CH1 in use, and sends it to all emergency vehicles 8. Simultaneous command can be sent. Therefore, according to the communication command system according to the embodiment, the simultaneous command can be quickly transmitted to all the emergency vehicles 8.

  Moreover, the command stand (# 2) 1 according to the embodiment is an example of a communication command device, and includes a control unit 10 and a stand input / output device 12. The command board (# 2) 1 selects unused radio channels CH2 and CH3 from a plurality of radio channels CH1 to CH3 for communicating with the emergency vehicle 8, and the emergency vehicle 8 that is selecting the radio channels CH2 and CH3. Then, communication is performed via a wireless communication device 2 including a plurality of wireless channels CH1 to CH3.

  When receiving an emergency call, the control unit 10 selects unused radio channels CH2 and CH3, and transmits a command to the emergency vehicle 8 that is selecting the radio channels CH2 and CH3. The stand input / output device 12 transfers the command to the other command stand (# 1) 1.

  The control unit 10 discriminates the radio channel CH1 being used from the plurality of radio channels CH1 to CH3, and transfers the radio channel CH1 to the other command board (# 1) 1 that is selected by the base input / output device 12. Is instructed to superimpose the received command on the communication of the wireless channel.

  For this reason, the command stand (# 2) 1 does not wait for the end of the communication of the command stand (# 1) 1 or forcibly releases the radio channel CH1 in use, and sends it to all emergency vehicles 8. Simultaneous command can be sent. Therefore, according to the communication command device according to the embodiment, the simultaneous command can be quickly transmitted to all the emergency vehicles 8.

In addition, the communication command method according to the embodiment selects an unused radio channel from the plurality of radio channels CH1 to CH3 for communicating with the emergency vehicle 8, the emergency vehicle 8 that is selecting the radio channel, and the plurality of radio channels In the communication command method for communicating via the wireless communication device 2 having a wireless channel, the following steps are performed.
