Description

The present invention relates to a firefighting command system, a firefighting command control device, a firefighting digital wireless line control device, and a firefighting command transmission program, and in particular, in a firefighting command system having a firefighting digital wireless line control device, a large number of people when a wide area large-scale disaster occurs The present invention relates to a fire-fighting command system, a fire-fighting command control device, a fire-fighting digital wireless line control device, and a fire-fighting command transmission program that efficiently share information on disaster support activities.

When an emergency situation related to fire and emergency occurs, the fire department head office accepts it as a disaster case, records various information related to the disaster case as disaster case data, and provides command information for responding to the disaster case to the disaster case. We dispatch to each fire department and each firefighter to work on and perform firefighting emergency activities. In order to further enhance the fire fighting and emergency activities and improve the confidentiality of communication, in recent years, the shift to the fire fighting digital wireless communication system has been earnestly promoted. In this firefighting digital wireless communication system, a wireless SCPC (Single Channel Per Carrier) using 260 MHz band is used as a firefighting emergency radio system in which information such as commanders is transmitted from the command post of the fire department headquarters to firefighters operating at each disaster site. ) Method is adopted as the basis.

On the other hand, the fire brigade members who belong to the local fire brigade that performs various types of fire and emergency support activities for emergency situations contact the fire brigade headquarters that is responding to the emergency with a mobile phone, etc., and dispatch from the fire brigade headquarters. It prepares for dispatch before the instructions arrive, and obtains information on the status of fire and emergency activities during disaster cases.

Further, in recent years, regarding a fire-fighting command system using a digital wireless communication system, for example, Japanese Patent Laid-Open No. 2010-232965 “Fire-fighting emergency wireless system, base station device and fire-fighting emergency information transmitting method” and Patent Document 2 are disclosed. Various concrete realization methods such as Japanese Patent No. 5469152 “Fire command system and support dispatch method” have been actively proposed and are being put into practical use.

The technique described in Patent Document 1 proposes a technique relating to the configuration of a base station device, and is for voice signals transmitted and received to and from a firefighter digital radio transmission/reception terminal (radio device) of a firefighter corresponding to a disaster case. It proposes a mechanism to automatically switch the wireless channel of the one to the optimum one. Thus, it is possible to quickly send and receive emergency information regarding the disaster case.

Moreover, the said patent document 2 has proposed the technique regarding selection and dispatch of an emergency vehicle. This technology is equipped with a server shared by the fire department headquarters that has signed a fire support agreement. The server is configured to have a function of selecting an emergency vehicle according to the type of emergency case and the disaster occurrence point. Thus, it is possible to quickly select and dispatch an emergency vehicle.

Further, an outline of the current system configuration when the firefighting digital wireless communication system is adopted as a firefighting command system for instructing firefighting emergency activities is as shown in FIG. FIG. 15 is a system configuration diagram showing an outline of a system configuration of a firefighting command system in the current technology, and also describes operational problems in the firefighting command system. The entire configuration shown in FIG. 15 is referred to as a fire command system 100A.

As shown in FIG. 15, a firefighting command system 100A in the current technology includes a firefighting command control device 10 and a firefighting digital wireless line control device 20. A command line 30, a fire fighting digital radio line controller 20, and the like are connected by wire to the fire fighting command control device 10 that controls the exchange of information such as commands related to fire fighting and emergency activities. On the other hand, a base station wireless device 40 located in various places is wirelessly connected to the fire fighting digital wireless line control device 20 that controls the transmission/reception operation of a wireless signal by the fire fighting digital wireless communication system. In the following description, the base station wireless device 40 is described as a base station wireless device arranged near the disaster point.

The fire-fighting command control device 10 is one of the devices that compose the fire-fighting command system 100A, and accommodates various lines such as a command line, an emergency call line, a command line, and a fire-fighting wireless line. It is a type of private branch exchange that realizes circuit switching. In addition, the command board 30 connected to the fire command control device 10 via the command line is used to receive an emergency call (call 119), transmit voice information related to the command to the fire fight radio line, and send from the fire fight radio line. This is a terminal for receiving voice information.

Further, the firefighting digital wireless line control device 20 is one of the devices that make up the firefighting command system 100A, but is a kind of private branch exchange that realizes circuit switching between the firefighting command control device 10 and the base station wireless device 40. Is. Then, the voice information from the fire-fighting wireless line is transmitted to the base station wireless device 40 designated by the fire-fighting command control device 10 at the designated frequency, and the voice information from the base station wireless device 40 is transmitted to the fire-fighting command control device. Send to 10 via the fire brigade. In addition, the base station wireless device 40 has a function of performing wireless communication with a firefighting digital wireless transmission/reception terminal (radio device, that is, a mobile station) of a firefighter located in the vicinity.

It should be noted that the fire fighting digital radio line control device 20 uses a different frequency of the fire fighting digital radio for each disaster case to transmit and receive voice information regarding fire fighting and ambulance. The book is connected. The fire-fighting wireless line is a fire-fighting wireless line (up, down) for transmitting and receiving voice information regarding each disaster case between the fire-fighting command control device 10 and the base station wireless device 40. The fire-fighting wireless line (uplink) is a line mainly used for communication from the commander of the commander of the fire-fighting headquarters to the fire-fighting digital radio transmission/reception terminal (radio device) of a firefighter. On the other hand, the fire-fighting radio line (down) is a line used for communication from the fire-fighting digital radio transmission/reception terminal (radio device) of the firefighter to the command desk of the commander of the fire-fighting headquarters. Here, even in the same disaster case, it is possible to use a different firefighting radio line for each disaster point (that is, a line that handles information of different frequencies as the frequency of the firefighting digital radio depending on the disaster point). In the example shown in FIG. 15, as the fire fighting radio line, the first fire fighting radio line 1a and the second fire fighting radio line 1a are used for transmitting and receiving information using two frequencies of the fire fighting digital radio corresponding to the number of disaster points in the same disaster case. Firefighting wireless line 1b is connected.

Here, the firefighting digital radio transmission/reception terminal (radio device) installed in an emergency vehicle on which each firefighter is aboard or in each fire station where the firefighter is seated is the frequency of the firefighting digital radio that can simultaneously transmit and receive. Since the number of waves is limited to only one wave, the fire fighting digital radio line controller 20 is limited to one frequency that can be set at the same time with a certain base station radio device 40. Therefore, as shown in FIG. 15, even if two firefighting radio lines, the first firefighting radio line 1a and the second firefighting radio line 1b, are set as the firefighting radio lines related to the same disaster case, at the same time, Information of two fire fighting radio lines cannot be transmitted and received to and from the fire fighting digital radio transmission/reception terminal (radio device), and it is necessary to narrow down to either one of the fire fighting radio lines, for example, the first fire fighting radio line 1a. ..

Therefore, the fire fighting digital wireless line control device 20 transmits and receives information on one of the narrowed down fire fighting wireless lines, for example, the first fire fighting wireless line 1a, to and from the designated fire fighting digital wireless transmission/reception terminal (radio device). become. Therefore, the transmission/reception of information about the other wireless line, for example, the information about the second fired wireless line 1b, to/from the fire fighting digital wireless transmission/reception terminal (radio device) is postponed. As a result, the transmission of information about the other fire-fighting radio line, for example, the second fire-fighting radio line 1b, is delayed.

Furthermore, regarding a fire brigade that carries out local fire brigade activities, for example, when disasters occur at multiple disaster points, such as in the case of a large-scale large-scale disaster, fire fighters who perform fire and emergency support activities at each of the disaster points. As shown in the schematic diagram of FIG. 16, the communication between the members and the commander of the fire department headquarters uses the radio of the mobile phone via the mobile phone network instead of using the radio line for the fire fighting radio. Become. Therefore, it is necessary to manually set up a communication line for the mobile terminal between the fire brigade member and the commander, and it becomes difficult to carry out sufficient fire brigade activities.

FIG. 16 is a schematic diagram for explaining the problems of the information development method regarding fire fighting and emergency activities in the current technology. As shown in FIG. 16, the firefighters carrying out firefighting and rescue activities at each disaster point of the disaster case a related to wide area large-scale disaster, that is, the first disaster point, the second disaster point, and the third disaster point are Using each of the fire fighting radio wave, the second fire fighting radio wave, and the third fire fighting radio wave as activity waves, a call can be made with the commander of the fire department headquarters (fire department). However, firefighters who are carrying out firefighting and rescue activities at each disaster point cannot grasp the state of other disaster points, and it is difficult to cooperate with firefighters at other disaster points. Furthermore, when a fire brigade member who is engaged in fire brigade activities in connection with this disaster case a tries to communicate with the commander of the fire department headquarters (fire department), he/she manually operates the mobile phone to access through the mobile phone network. It is necessary to make a call and it is not a quick contact method.

JP, 2010-232965, A Japanese Patent No. 5469152

As described above, the problems to be solved in the current technology related to the present invention are as follows.

The first problem is that, in the current operation method of firefighting digital wireless communication system, as in the case of a large-scale large-scale disaster, there are multiple disaster points at the same time, It means that it is not possible to smoothly share information on disasters.

The reason is that as the operation method of the current firefighting digital wireless communication system, when there are multiple disaster points at the same time, such as when a large-scale large-scale disaster occurs, the frequencies of multiple firefighting digital radios are used. Then, they are trying to share information between each disaster site activist and the commander. In other words, although each disaster site worker possesses 0 to 1 firefighting digital wireless transceiver terminals (radio devices), the firefighting digital wireless transceiver terminals (radio devices) can simultaneously transmit 1 wave. Information can be transmitted and received only with the frequency of the firefighting digital radio, and information cannot be transmitted and received simultaneously from multiple frequencies. Therefore, although it is possible to share information between each disaster site activist and the commander, it is difficult for firefighters active at other disaster points to quickly obtain the information.

The second problem is that information cannot be smoothly shared between the local fire brigade and the fire department (fire department).

The reason is that as a means of information transmission and cooperation between the local fire brigade and the fire department headquarters (fire department), it is not possible to use the frequency band for fire fighting digital radio, and there is no choice but to use mobile phone calls. Especially.

The third problem is that even in the case of a disaster activity when a plurality of disaster points are present at the same time, such as in the case of a large-scale large-scale disaster occurrence, it is possible to allocate only a predetermined number or more of frequencies for the fire fighting digital radio. This is something that cannot be done.

The reason for this is that the frequencies that can be used for the fire fighting digital wireless communication system have a narrow range in which frequencies can be assigned to each fire fighting headquarters, and each fire fighting headquarters can use only a limited frequency band. In other words, if multiple disaster points are present at the same time, a large number of digital frequencies for fire fighting will be assigned for communication to coordinate with each of the firefighters and fire brigade members who perform fire and emergency activities at each disaster point. , Fire and emergency activities related to other disaster cases will be hindered.

(Purpose of the present disclosure)
In view of the above problems, the purpose of the present disclosure is to share information between firefighters who are engaged in firefighting and emergency activities at each disaster location, even when disasters occur simultaneously at multiple disaster locations.

Yes.

(Characteristics of the present invention)
Prior to the description of the embodiments of the present invention, an outline of the features of the present invention will be first described. The present invention, in a firefighting command system having a firefighting digital radio line controller, devises a method of using the firefighting digital radio for each disaster case to allocate an arbitrary number of radio frequencies within a limited radio resource range. The main feature is that it enables information to be shared among firefighters who are engaged in fire and emergency activities at each disaster case or at each of multiple disaster points in the same disaster case.

In particular, even when multiple disaster points exist at the same time, such as in the case of a large-scale large-scale disaster, fire and emergency activities are being carried out at each disaster point within the limited wireless resources. The main feature is to effectively share information among firefighters in Japan. Furthermore, it is also a major feature that information is effectively shared between fire brigade members and firefighters/commanders who are engaged in fire and emergency support activities at each disaster site within the limited wireless resources. Thus, by improving the efficiency of the use of wireless resources, it is possible to avoid exhaustion of radio frequency even if multiple disaster cases occur at the same time, and fire emergency personnel (firefighters, commanders) in each disaster case. Information sharing among staff members and fire brigade members).

The features of the present invention will be described more specifically with reference to FIG. FIG. 1 is a system configuration diagram showing an example of the outline of the system configuration of a fire command system according to the present invention, and describes a technique for solving the operational problem in the current fire command system shown in FIG. ..

The fire-fighting command system 100 according to the present invention shown in FIG. 1 also has a fire-fighting command control device 10 and a fire-fighting digital wireless line control device 20, similar to the fire-fighting command system 100A in the current technology shown in FIG. The fire-fighting command control device 10 controls a transmission/reception operation of voice information regarding a command from a commander of the fire department headquarters and voice information from a firefighter at a disaster point. Further, the fire-fighting digital wireless line control device 20 changes the voice information transmitted and received between the commander of the fire-fighting headquarters and the firefighters at the disaster point by different firefighting digital signals for each disaster case or for each disaster point related to the same disaster case. Controls the operation of sending and receiving by the firefighting digital wireless communication system using the radio frequency. A command line 30 and the like are connected to the fire command control device 10 by wire, and a base station wireless device 40 at a disaster point is wirelessly connected to the fire fighting digital wireless line control device 20.

The fire-fighting command control device 10 and the fire-fighting digital wireless line control device 20 are one of the devices configuring the fire-fighting command system 100, like the fire-fighting command system 100A in the current technology shown in FIG. Further, the command board 30 connected to the fire command system 10 via the command line also receives an emergency call (119 call), a fire fighting wireless line, as in the fire fighting command system 100A in the current technology shown in FIG. Is a terminal for transmitting voice information related to a command to and receiving voice information from the fire fighting wireless line. Further, the base station wireless device 40 also has a function of performing wireless communication with a firefighting digital wireless transmission/reception terminal (radio device, that is, a mobile station) similarly to the firefighting command system 100A in the current technology shown in FIG. ..

However, in the firefighting command system 100 according to the present invention shown in FIG. 1, the line configuration for connecting between the firefighting digital wireless line control device 20 and the firefighting command control device 10 has a firefighting command in the current technology shown in FIG. This is different from the case of the system 100A. That is, the firefighting digital wireless line control device 20 is the same line as the case of the firefighting command system 100A in the current technology shown in FIG. 15 as a line for transmitting and receiving voice information to and from the firefighting digital wireless line control device 20, that is, , Not only connecting the fire-fighting wireless line (up, down) that transmits and receives voice information between the commander and the firefighters who are active in the disaster case. In addition, the fire-fighting digital wireless line control device 20 serves as a line for transmitting and receiving voice information to and from the fire-fighting digital wireless line control device 20, and collects up-and-down voice information for each disaster point related to the same disaster case in one direction. Firewireless radio communication voice transmission line (downlink) to be transmitted only to all, and information sharing firefighting radio line (uplink and downlink) that collectively transmits and receives all voice information to share voice information of each disaster point related to the same disaster case Are further connected.

As described above, as for the fire-fighting radio lines (up and down), as in the case of FIG. 15, mainly the command board used by the commander of the fire department and the fire-fighting digital radio used by firefighters who are engaged in fire and emergency activities. This line is used when transmitting and receiving voice information to and from a transmitting/receiving terminal (radio device), and different frequencies of the fire fighting digital radio are assigned to each disaster case. However, even in the same disaster case, different frequencies may be assigned to different disaster points. In the example shown in FIG. 1, as in the case of FIG. 15, the case where the first fire-fighting radio line 1a and the second fire-fighting radio line 1b are connected as the fire-fighting radio line corresponding to the disaster point of the same disaster case Shows.

The fire fighting radio communication voice lead-in line (downlink) is a line having a function of transmitting voice information from the fire fighting digital radio line controller 20 to the fire command control unit 10 in one direction. Then, the fire fighting radio communication voice service line (downlink) outputs an upstream voice signal and downstream voice information for each same disaster case to which the same frequency is assigned or for each disaster point of the same disaster case. It is a line for transmitting one piece of voice information as communication voice information to the fire command control device 10.

In the example shown in FIG. 1, a first fire fighting radio communication voice drawing line 2a and a second fire fighting radio communication voice drawing line 2b are connected as the fire fighting radio communication voice drawing line. In the first fire fighting radio communication voice lead-in line 2a, in the fire fighting digital radio line control device 20, the voice information of the up and down directions of the first fire fighting radio line 1a is collected into one and the fire command control device 10 is provided. Is transmitted to the second fire fighting radio communication voice access line 2b, the fire fighting digital radio line controller 20 collects the voice information of the up and down directions of the second fire fighting radio line 1b into a single fire information. It is sent to the command control device 10.

Although not shown in FIG. 1, the fire fighting digital radio line control device 20 has an up/down direction in each frequency of the fire fighting digital radio transmitted/received to/from the fire command control device 10 via the fire fighting radio line. It has an upper and lower audio mixing circuit for mixing the audio information of each frequency for each frequency so that the upstream/downward audio information can be treated as if it were one audio information. Hereinafter, the voice information after mixing will be referred to as “communication voice information”.

That is, the first fire communication radio line 1a is mixed with the upstream and downstream voice information to generate the first communication voice information, and the second fire communication radio line 1b is mixed with the upstream and downstream voice information. Then, the second communication voice information is generated. Thereafter, the fire fighting digital radio line controller 20 sends the generated first communication voice information to the fire command control device 10 via the first fire fighting radio communication voice drawing-in line 2a, as shown in FIG. The generated second communication voice information is sent to the fire-fighting command control device 10 via the second fire-fighting wireless communication voice lead-in line 2b.

In addition, the fire-fighting wireless line for information sharing (up and down) is similar to the function of the fire-fighting wireless line, and is mainly used by the commander used by the commander of the fire department headquarters and the fire-fighting digital device used by firefighters who are engaged in fire and emergency activities. A line used when transmitting and receiving voice information to and from a wireless transmission/reception terminal (radio device). However, the information sharing firefighting wireless line (uplink, downlink) can also be used for information sharing, and it is also possible to collectively send and receive voice information flowing in all firefighting wireless lines related to the same disaster case. Is. In other words, the information sharing firefighting wireless line (up, down) is different from the firefighting wireless line, and the voice information flowing through all the firefighting wireless lines related to the same disaster event is collected as one voice information as the information sharing voice information. The fire fighting digital wireless line control device 20 and the fire fighting command control device 10 are capable of transmitting and receiving. In addition, the information sharing fire fighting radio line (up, down) includes the number of disaster points that are the destinations for transmitting the information sharing voice information, the number of fire fighting digital wireless transmission/reception terminals (radio devices), disaster cases, disaster types, Any number of items may be prepared in advance in consideration of disaster points and the like.

In the example shown in FIG. 1, only one first information sharing fire fighting wireless line 3a is connected as an information sharing fire fighting wireless line. Then, in the fire command control device 10, the communication voice information received via the first fire fighting radio communication voice drawing line 2a and the communication voice information received via the second fire fighting radio communication voice drawing line 2b are used for the same disaster. All the voice information related to the case is collected into one, and the voice information for information sharing is sent to the fire fighting digital radio channel controller 20 using the upstream line of the first information sharing fire fighting radio line 3a.

The fire-fighting digital wireless line control device 20 uses the received information-sharing voice information by using a predetermined frequency as an information-sharing frequency for the first information-sharing fire-fighting wireless line 3a among the frequencies of the fire-fighting digital radio. It transmits via the base station radio|wireless apparatus 40 to the firefighting digital radio transmission/reception terminal (radio machine) of each firefighter corresponding to the disaster case. Therefore, by adjusting the fire-fighting digital radio transmission/reception terminal (radio device) used by each firefighter to the information sharing frequency, all voice information related to the disaster case, that is, communication voice information about the first fire-fighting wireless line 1a and 2 It is possible to collectively listen to the communication voice information regarding the fire brigade wireless line 1b.

Thus, even if disasters occur simultaneously at a plurality of disaster points, such as a wide area large-scale disaster, the radio frequency is not exhausted, and each base station wireless device 40 can be used by all the disaster points in the same disaster case. It is possible to collectively receive up and down voice information transmitted and received for fire fighting and emergency activities, and to share information among fire fighting emergency workers (firefighters) corresponding to the same disaster case. You can

In addition, in order to enable information sharing not only by the firefighters who respond to the disaster case, but also by members of the local fire brigade who carry out fire and emergency support activities for the disaster case, It can also be used to transmit information sharing voice information related to the disaster case to a firefighting digital radio transmission/reception terminal (radio device) used by a fire brigade member in the area.

Furthermore, the local fire brigade members can use the information sharing frequency of the fire fighting digital radio to use the up and down lines of the information sharing fire fighting radio line to enable fire fighting with the commander of the fire department headquarters. It is also possible to exchange information regarding emergency support activities.

Therefore, the local fire brigade members can easily use all the voice information exchanged between the firefighters and the commander at each disaster point by using the firefighting digital radio transmission/reception terminal (radio) for the firefighting digital radio. In addition, it is possible to hear promptly, and it is also possible to quickly exchange information regarding fire and emergency support activities with the commander.

FIG. 2 is a schematic diagram for explaining an example of a method of developing information regarding fire and emergency activities in the fire command system according to the present invention. As shown in FIG. 2, in the fire command system according to the present invention, the call information (conversation voice) between the fireman and the commander of the fire department headquarters (fire department) at each disaster point related to the disaster case a of the wide area large-scale disaster. Mixing is performed to generate information sharing voice information that is a collection of all call information.

In FIG. 2, for example, in order for a firefighter at the second disaster point to grasp the state of other disaster points, the frequency of the firefighting digital radio transmission/reception terminal (radio device) used by the firefighter is set with the commander. If you switch to the frequency for the information sharing wireless line (information sharing firefighting radio wave) instead of the frequency for the second firefighting wireless line used for calls (second firefighting radio wave), the voice information for information sharing Can be heard and voice information regarding other disaster points can be obtained.

In addition, if a local fire brigade member who is engaged in fire brigade activities in connection with this disaster event a wants to know the activity status of firefighters at each disaster point, the firefighting digital radio used by the local fire brigade members If the frequency of the transmission/reception terminal (radio device) is matched with the frequency for the information sharing wireless line (information sharing firefighting radio wave), it becomes possible to listen to the information sharing voice information. In addition, when a fire brigade member wants to keep in touch with the commander of the fire department headquarters (fire department) about fire and emergency support activities, information on the frequency of the digital fire transmitter/receiver terminal (radio) used by the fire brigade members in the area is shared. You can easily communicate with the commander by setting the frequency for the wireless communication line (radio wave for information sharing).

(Example of configuration of the embodiment of the present invention)
Next, an example of the system configuration of the fire command system according to the present invention will be described in detail with reference to FIG. FIG. 3 is a system configuration diagram showing an example of the system configuration of the fire command system according to the present invention. The entire system having the configuration shown in FIG. 3 is called a fire command system 100. As shown in FIG. 3, the firefighting command system 100 includes one or a plurality of firefighting wireless lines and one or a plurality of firefighting wireless communication voice connection lines between the firefighting command control device 10 and the firefighting digital wireless line control device 20. And one or more information sharing fire fighting wireless lines.

Although not shown in FIG. 3, the fire-fighting command control device 10 is wire-connected to a fire-fighting digital wireless transmission/reception terminal such as a command board operated by a commander of the fire department headquarters via a command board line. Further, the fire station digital radio line control device 20 is wirelessly connected to base station radio devices arranged in various places. Here, the base station wireless device is also arranged near the disaster point of each disaster case. Then, the fire fighting digital radio line control device 20 wirelessly communicates with the fire fighting digital radio transmission/reception terminal (radio device) used by the firefighter who is engaged in firefighting and rescue activities at the disaster point of each disaster case via the base station radio device. Connecting.

The plurality of fire fighting radio lines are lines to which different frequencies for digital fire fighting radio are assigned for each disaster case or for each disaster point of the same disaster case. As shown in FIG. 3, for example, the first fire fighting radio line 1a is used. , The second fire-fighting radio line 1b,... And, one or more fire-fighting wireless lines are used by the firefighters who are engaged in fire-fighting and emergency activities at the terminal used by the dispatcher who is in charge of the fire-fighting command work of each disaster case at the fire department headquarters and at each disaster point of each disaster case. The fire-fighting command control device 10 and the fire-fighting digital wireless line control device 20 are connected in order to transmit and receive call voice information to and from the fire-fighting digital radio transmission/reception terminal (radio device).

As shown in FIG. 3, the fire fighting digital wireless line control device 20 has a vertical audio mixing circuit 21 inside. The upper and lower audio mixing circuit 21 transmits and receives downlink audio information and downlink information at each frequency of the fire fighting digital radio for each disaster case transmitted to and from the fire command control device 10 via each fire fight radio line or for each disaster point of the same disaster case. The audio information is mixed for each frequency, and the upstream audio information and the downstream audio information are collected so that they can be treated as if they were one audio information. The voice information after mixing is called “communication voice information”. For example, the up-and-down audio mixing circuit 21 mixes the upstream and downstream audio information of the first fire fighting radio line 1a to generate the first communication audio information, and the up and down direction of the second fire fighting radio line 1b. Downstream voice information is mixed to generate second communication voice information.

Thereafter, as shown in FIG. 3, the fire fighting digital radio line control device 20 outputs the communication voice information generated for each frequency for the fire fighting digital radio among the one or a plurality of fire fighting radio communication voice drawing lines. It is sent to the fire-fighting command control device 10 through the fire-fighting radio communication voice lead-in line corresponding to the frequency for the fire-fighting digital radio used for each disaster case or each disaster point of the same disaster case. For example, the first communication voice information is sent to the fire-fighting command control device 10 via the first fire-fighting radio communication voice lead-in line 2a corresponding to the frequency of the fire-fighting digital radio of the first fire-fighting radio line 1a, and the second communication voice is transmitted. The information is sent to the fire-fighting command control device 10 through the second fire-fighting radio communication voice drawing-in line 2b corresponding to the frequency of the fire-fighting digital radio of the second fire-fighting radio line 1b.

The fire-fighting command control device 10 has an information sharing voice mixing circuit 11 therein. The information sharing voice mixing circuit 11 mixes all of a desired number of communication voice information transmitted from the fire fighting digital radio line control device 20 via each of the one or more fire fighting radio communication voice service lines and mixes them. One voice information is collected and generated as voice information for information sharing. For example, all the first communication voice information transmitted through the first fire fighting radio communication voice drawing line 2a and the second communication voice information transmitted through the second fire fighting radio communication voice drawing line 2b. The communication voice information is mixed into one voice information and is generated as information sharing voice information capable of sharing the information.

Thereafter, the fire command control device 10 sets the information sharing voice information generated in the information sharing voice mixing circuit 11 to the information of the number corresponding to a predetermined arbitrary number of frequencies of the plurality of fire fighting digital radio frequencies. It is sent to the fire fighting digital radio line controller 20 via the shared fire fighting radio line. Here, among a plurality of frequencies of the fire fighting digital radio, a predetermined number of frequencies are used for disaster incidents, disaster points, disaster types occurring at the same point in time, and firefighters who are engaged in fire and emergency activities. The number of frequencies is determined according to the radios to be used and the radios used by the members of the fire brigade of the local fire brigade that performs fire and emergency support activities.

In FIG. 3, for example, when the first communication voice information and the second communication voice information are information related to the same disaster case, for example, disaster case a, the information sharing voice information generated in the information sharing voice mixing circuit 11 To the fire fighting digital radio line controller 20 via the first information sharing fire fighting radio line 3a, which handles a predetermined frequency among the plurality of information sharing fire fighting radio lines as the information sharing frequency relating to the disaster case a. Send out.

Then, the fire fighting digital wireless line control device 20 uses the information sharing voice information transmitted from the fire fighting command control device 10 via each of the arbitrary number of information sharing fire fighting wireless lines as the information sharing frequency for the fire fighting digital wireless. Using a radio frequency determined in advance, the radio frequency is transmitted to each base station radio device to which the radio corresponding to the destination belongs.

As a result, each base station wireless device to which the wireless device corresponding to the destination belongs receives the information sharing voice information transmitted from the fire fighting digital wireless line control device 20 using the information sharing frequency, and It is possible to transmit to each radio device to which it belongs by using the information sharing frequency. Therefore, even if there are multiple disaster cases or multiple disaster points related to the same disaster case at the same time, the radio frequency for the digital fire fighting radio will not be exhausted, and Each fire brigade member can collectively receive up and down voice information transmitted and received for all disaster cases or all disaster points related to the same disaster case, and information of the fire emergency personnel in each disaster case. Can be shared.

Although not shown in FIG. 3, one or more fire fighting radio communication voice lead-in lines connected to the input side of the information sharing voice mixing circuit 11 are connected to one or more fire fighting lines as described above. From the wireless communication voice lead-in lines, select only a plurality of fire fighting wireless communication voice lead-in lines that output communication voice information relating to the same disaster case, and connect them to the input side of the information sharing voice mixing circuit 11. It is possible to generate communication voice information relating to the same disaster case as voice information for information sharing, which is collected as one voice information.

Furthermore, not all communication voice information regarding the same disaster case, but instructions from multiple fire fighting radio communication voice service lines that output communication voice information regarding the same disaster case based on instructions from the commander. It is also possible to generate only the communication voice information related to the fire fighting radio communication voice service line as the voice information for information sharing, which is collected as one voice information. Then, of the plurality of fire fighting radio communication voice service lines that output communication voice information related to the same disaster case, only the communication voice information related to the designated fire service radio service voice service line is collected into one voice information. As a destination for transmitting the shared voice information, the commander can also target the wireless device used by the fire brigade member of the local fire brigade.

It is assumed that the three frequencies of A/B/C Hz are used as the frequency of the fire fighting digital radio used for the communication with the staff. In addition, as a frequency of the firefighting digital radio used to plan information sharing regarding this disaster event a to the fire and emergency response personnel (firefighting team members, etc.) in the local fire brigade related to this disaster event a of wide area large-scale disaster, It is assumed that two predetermined frequencies of D/E Hz are used.

The firefighter who is active at the first disaster point uses the radio wave of frequency A Hz as the activity wave and transmits the firefighting digital radio line from the first base station radio device 40a installed near the first disaster point. A call is being made with the commander via the control device 20 and further via the first fire fighting radio line 1a and the fire command control device 10. In addition, the firefighter who is active at the second disaster point similarly uses the radio wave having the frequency B Hz as the active wave, and the second base station wireless device 40b installed near the second disaster point. To the commander via the fire-fighting digital wireless line control device 20, and further via the second fire-fighting wireless line 1b and the fire-fighting command control device 10.

To the commander via the fire-fighting digital wireless line control device 20, and further via the third fire-fighting wireless line 1c and the fire-fighting command control device 10.

The fire fighting digital radio network controller 20 mixes up and down call information between the firefighter and the commander at the first disaster point as communication voice information in the upper and lower voice mixing circuit 21 provided therein. Then, it is sent to the fire-fighting command control device 10 via the first fire-fighting wireless communication voice lead-in line 2a corresponding to the radio wave of the frequency A Hz. Similarly, the up and down call information between the fireman and the commander at the second disaster point and between the fireman and the commander at the third disaster point are mixed as communication voice information, The signal is transmitted to the fire-fighting command control device 10 via the second fire-fighting wireless communication voice lead-in line 2b and the third fire-fighting wireless communication voice lead-in line 2c corresponding to the radio waves of frequency B Hz and frequency C Hz, respectively.

The communication voice information transmitted between the firefighters and the commander at each of the first disaster point, the second disaster point, and the third disaster point sent out via each of the voice service lines 2c is all in one. Collectively output as voice information for information sharing.

Then, the information sharing voice information output from the information sharing voice mixing circuit 11 is the first information sharing fire station corresponding to the radio waves of the frequencies D and E Hz of the fire fighting digital radio set in advance as the information sharing frequency. It is sent to the fire fighting digital radio line controller 20 via each of the radio line 3a and the second information sharing fire fighting radio line 3b.

When the fire fighting digital wireless line control device 20 receives the information sharing voice information from each of the first information sharing fire fighting wireless line 3a and the second information sharing fire fighting wireless line 3b, it is associated with the wide area large-scale disaster a. In order to notify the fire brigade members in each of the regions A and B, the received information sharing voice information is transmitted to the fourth base station wireless device 40d and the fifth base station wireless device 40d using the wireless waves of the information sharing frequencies D and E Hz, respectively. It transmits to each base station radio|wireless apparatus 40e. The fourth base station wireless device 40d and the fifth base station wireless device 40e each receive the received information sharing voice information by using the radio waves of the information sharing frequencies D and E Hz, respectively, in the area A and the area B, respectively. Notify the radios used by members of the local fire brigade.

In the present embodiment, the case where two frequencies D and E Hz are used as the number of frequencies of the fire-fighting digital radio determined in advance as the information sharing frequency is shown, but as described above, it corresponds. The number may be arbitrary according to various situations related to the disaster case.

Although not shown in FIG. 3, the fire-fighting digital wireless line control device 20 uses the information-sharing voice information received from the fire-fighting command control device 10 by using radio waves of information sharing frequencies D and E Hz, respectively. , The first base station wireless device 40a, the second base station wireless device 40b, and the third base station wireless device 40c. Each of the first base station wireless device 40a, the second base station wireless device 40b, and the third base station wireless device 40c uses the received information sharing voice information by using the respective radio waves of the information sharing frequencies D and E Hz. , It transmits to the radio equipment owned by the firefighter belonging to each base station radio equipment.

Therefore, the frequency of the fire fighting digital radio transmission/reception terminal (radio device) used by the firefighters engaged in firefighting and rescue activities at the first disaster point, the second disaster point, and the third disaster point is set to the information sharing frequencies D and E Hz. If combined, each firefighter who is engaged in firefighting and rescue activities at each of the first disaster spot, the second disaster spot, and the third disaster spot can also listen to the information sharing voice information.

The flow of operations in the flowchart shown in FIG. 4 will be described below. First, when a wide area large-scale disaster occurs, a wide area disaster case a is generated by the fire department headquarters, and as shown in FIG. 6, the first disaster is set as the frequency of the fire fighting digital radio for fire rescue activities related to the wide area disaster case a. It is decided to use A Hz for the spot, B Hz for the second disaster spot, and C Hz for the third disaster spot (step S1).

FIG. 6 is a schematic diagram showing the usage of the communication line of the fire command system 100 in step S1 of the flowchart shown in FIG. That is, the call information between the commander of the fire department and the firefighters active at each disaster point is, for example, in the case of a call with the fireman at the first disaster point, For communication between the two, using the frequency A Hz for the fire fighting digital radio, from the first base station radio device 40a via the fire fighting digital radio line control device 20, and further, the first fire fighting radio line 1a and the fire command command control. They are mutually transmitted and received via the device 10.

Thus, when the frequency of the fire-fighting digital radio for communication between the commander of the fire-fighting headquarters and the fire-fighters active at each disaster point related to the wide area disaster case a is determined, the fire-fighting digital radio line control device 20 Next, as shown in FIG. 7, built-in upper and lower audio for each frequency (A/B/C Hz) for the fire fighting digital radio assigned to voice information transmitted and received using each fire fighting radio line The respective mixing circuits 21 are secured, and the outputs from the fire fighting radio line side and the output from the base station radio device side regarding the corresponding frequencies (A/B/C Hz) are provided to the input sides of the respective upper and lower audio mixing circuits 21. Are connected (step S2).

FIG. 7 is a schematic diagram showing the usage status of the communication line of the fire command system 100 in step S2 of the flowchart shown in FIG. As a result, the audio information in the up and down directions between the commander of the fire department and the firefighters active at each disaster point related to the wide area disaster case a is mixed for each frequency for the digital fire radio. , Is output from each upper/lower audio mixing circuit 21 as communication voice information for each upper/lower audio mixing circuit 21.

That is, for example, using the frequency A Hz for fire fighting radio, regarding the communication path between the fireman and the commander at the first disaster point, the output from the first base station radio device 40a and the first fire fighting radio The output from the line 1a side is connected to the input side of the first upper and lower audio mixing circuit 21a. As a result, the audio information of the up and down directions between the firefighters active at the first disaster point related to the wide area disaster case a and the commander of the fire department headquarters is mixed, and the frequency A Hz for firefighting digital radio is mixed. Will be output from the first upper and lower audio mixing circuit 21a as the first communication audio information corresponding to the above.

Next, as shown in FIG. 8, the fire fighting digital radio line control device 20 outputs the respective output sides of the upper and lower audio mixing circuits 21 for each frequency (A/B/C Hz) assigned for the fire fighting digital radio, It connects to the input side of the fire fighting radio communication voice service line of the corresponding frequency (A/B/C Hz) (step S3).

FIG. 8 is a schematic diagram showing the usage status of the communication line of the fire command system 100 in step S3 of the flowchart shown in FIG. As a result, the communication voice information generated by mixing in each upper and lower audio mixing circuit 21 is output from each upper and lower audio mixing circuit 21 for each frequency (A/B/C Hz) assigned for fire fighting digital radio. It is sent to the fire command control device 10. That is, for example, regarding the call route connecting the firefighter and the commander at the first disaster point using the frequency A Hz for fire fighting radio, the first communication voice information is the first upper and lower voices. It is sent from the mixing circuit 21a to the fire-fighting command control device 10 through the first fire-fighting wireless communication voice lead-in line 2a.

As shown in FIG. 9, the fire-fighting command control device 10 includes all the output sides of the wireless communication voice lead-in line from the fire-fighting digital wireless line control device 20 on the input side of the built-in information sharing voice mixing circuit 11. Connect (step S4). Therefore, all the communication voice information input via the line for the fire fighting radio communication voice service for each frequency (A/B/C Hz) assigned for the fire fighting digital radio is built in the fire command control device 10. The information is input to the information sharing voice mixing circuit 11.

FIG. 9 is a schematic diagram showing the use status of the communication line of the fire command system 100 in step S4 of the flowchart shown in FIG. As a result, all communication voice information between the firefighters active at each disaster point and the commander of the fire department headquarters is mixed in the wide area disaster case a, and the information sharing voice mixing circuit is used as the information sharing voice information. It is output from 11.

That is, all communication voice information related to the wide area disaster case a (that is, the first communication voice information, the second communication voice information, the third communication voice information between the firefighter and the commander at each of the first, second, and third disaster points). (Communication voice information) is collected into one and output from the information sharing voice mixing circuit 11 as information sharing voice information.

Next, as shown in FIG. 10, the fire-fighting command control device 10 outputs, at the output side of the information-mixing audio mixing circuit 11, an information-sharing fire-fighting radio corresponding to the frequency of the fire-fighting digital radio that is predetermined as the information-sharing frequency. The respective input sides of the lines are connected (step S5).

FIG. 10 is a schematic diagram showing the usage status of the communication lines of the fire command system 100 in step S5 of the flowchart shown in FIG. As a result, the information sharing voice information generated by being mixed and combined in the information sharing voice mixing circuit 11 is used for information sharing corresponding to each frequency of the fire fighting digital radio that is predetermined as the information sharing frequency. It is sent to the fire fighting digital radio line controller 20 via the fire fighting radio line. That is, for example, when two frequencies for fire fighting radio, D Hz and E Hz, are allocated as the information sharing frequencies, the information sharing voice information combined into one is the respective information sharing frequencies. It is sent to the fire fighting digital radio line controller 20 via the first information sharing fire fighting radio line 3a and the second information sharing fire fighting radio line 3b corresponding to D Hz and E Hz. The number of information sharing frequencies and the number of information sharing fire fighting wireless lines are not limited to these two, and any number can be set.

Finally, the fire fighting digital wireless line control device 20 that has received the information sharing voice information transmitted from the information sharing voice mixing circuit 11 of the fire command control device 10 receives the information sharing voice information as shown in FIG. The voice information is transmitted to the base station wireless device in the vicinity where each fire brigade member who is related to the wide area disaster case a is located as a radio wave of the frequency of the fire fighting digital radio set in advance as the information sharing frequency (step S6).

FIG. 11 is a schematic diagram showing the usage status of the communication line of the fire command system 100 in step S6 of the flowchart shown in FIG. As a result, each fire brigade member located in the radio area near each base station radio device uses the reception radio frequency of the fire fighting digital radio transmission/reception terminal (radio device) used by each as the information sharing frequency in advance. It is possible to listen to the call information between the firefighters and the commander at each disaster point by adjusting the frequency of the determined firefighting digital radio.

For example, when two frequencies, D Hz and E Hz, for the fire fighting digital radio are used as frequencies for information sharing, as shown in FIG. 11, the fire fighting station located near the fourth base station radio unit 40d If the reception radio frequency of the fire-fighting digital radio transmission/reception terminal (radio device) is adjusted to the fire-fighting radio frequency D Hz, the firefighter and the commander at the first disaster point will use the fire-fighting digital radio frequency A Hz. Voice information being communicated, voice information being communicated by the firefighter and commander at the second disaster point using the frequency B Hz of the firefighting digital radio, firefighters and commanders being fired at the third disaster point It is possible to hear all the communication voice information of the voice information which is being communicated using the frequency C Hz of the digital radio.

Note that the information sharing frequency is a frequency that has the functions of a normal firefighting digital radio, so if necessary, the fire brigade staff can hold a call button on the firefighting digital radio transmission/reception terminal (radio) that the fire brigade member possesses. It is also possible to perform a press talk with the commander of the fire department headquarters by using the information sharing frequency, for example, the fire fighting radio frequency D Hz, by performing the press operation.

Further, in the above explanation, the case where the fire brigade member related to the wide area disaster case a hears the information sharing voice information has been explained, but the firefighters who are engaged in fire emergency services at each disaster point of the wide area disaster case a also If necessary, you can listen to the information sharing voice information by adjusting the reception frequency of the fire fighting digital wireless transmission/reception terminal (radio) possessed by each to the information sharing frequency. ..

Further, in the above description, the case where the frequency of the fire fighting digital radio relating to the fire fighting radio line and the fire fighting radio communication voice lead-in line is three has been described, but the present invention is not limited to such a number, and the fire fighting radio is not limited thereto. Any number may be used as long as the frequency of the fire fighting digital radio relating to the line and the frequency of the fire fighting digital radio relating to the line for introducing the fire fighting radio communication voice are the same. Further, the frequency of the fire-fighting radio that is predetermined as the information sharing frequency is not limited to two as described above, and may be any number.

Further, in the above description, the upper and lower audio mixing circuit 21 is arranged in the fire fighting digital wireless line control device 20, and the information sharing audio mixing circuit 11 is arranged in the fire fighting command control device 10. The invention is not limited to such a configuration. For example, both the upper and lower audio mixing circuits 21 and the information sharing audio mixing circuit 11 may be arranged in the fire fighting digital wireless line control device 20, or in some cases, It may be arranged in the fire command control device 10. Further, the upper and lower audio mixing circuit 21 and the information sharing audio mixing circuit 11 are integrated, so that not only the upper and lower audio information is generated but also the information sharing audio information is generated all at once. It may be arranged as a voice mixing means) and arranged in the fire fighting digital radio network controller 20, or may be arranged in the fire fighting command controller 10 in some cases.

(Explanation of the effect of the embodiment)
As described in detail above, the following effects can be achieved in this embodiment.

The first effect is that even if a plurality of disaster points are present at the same time, such as in the case of a large-scale large-scale disaster, disaster site activists (fire fighters) who are engaged in firefighting and rescue activities at each of the plurality of disaster points. It is to be able to share each disaster information smoothly among each other.

The reason is that all the voice information transmitted and received between each disaster site activist (firefighter) and the commander is collected using each frequency of multiple firefighting digital radios assigned to each disaster point. This is because it has a mechanism for generating the information sharing voice information. Then, the generated information sharing voice information is used as the information sharing frequency of the firefighting digital radio by using a predetermined radio frequency, and the firefighting digital radio transmission/reception terminal (radio device used by each disaster site activist (firefighter) is used. This is because it has a mechanism for sending to Each disaster site activist (firefighter) adjusts the frequency of the firefighting digital wireless transmission/reception terminal (radio) used to the frequency for information sharing, so that each disaster site activist (firefighter) It is possible to obtain all the voice information transmitted and received between the commander and the commander all at once, and to share the information with other disaster site activists (firefighters).

The second effect is to be able to provide a mechanism for smoothly sharing information between members of the local fire brigade, the commander of the fire department and the firefighters at each disaster site.

The reason is to use the above-mentioned frequency band for information sharing of firefighting digital radio as a means of transmitting and linking information between firefighters members of the local firefighting team, commanders of the fire department headquarters and firefighters at each disaster point. Is possible.

The third effect is that even when a plurality of disaster points are present at the same time, such as in the case of a large-scale large-scale disaster, each of the disaster points can be optimally utilized by using limited wireless resources. It will be possible to share information during the fire and emergency activities in.

The reason is that it is possible to virtually allocate multiple frequencies to each disaster point by using an arbitrary number of information sharing frequencies of the above-mentioned fire fighting digital radio set as an appropriately usable number. This is because it has a mechanism.

The effects of the present embodiment described above will be further supplementarily described with reference to FIGS. 12, 13, and 14.

12, FIG. 13, and FIG. 14 all represent means for solving problems in information development in the current fire and emergency activities, but they are occurring at the same time to simplify the explanation. There are two types of disaster cases, Case A and Case B. For each disaster case, it is assumed that there are firefighters engaged in each disaster case and local fire brigade members involved in each case. .. In addition, the radio waves (that is, activity waves) transmitted and received between the firefighting digital radio transmission/reception terminal (radio set) used by each firefighter engaged in firefighting activities in Case A and Case B, respectively, and the fire department headquarters (fire station) , The first fire fighting radio wave (the frequency for the first fire fighting radio line) and the second fire fighting radio wave (the frequency for the second fire fighting radio line) are used.

Here, FIG. 12 is an explanatory diagram for explaining a first solution means that is assumed in solving a problem in information development in the current fire and emergency activities. FIG. 13 is an explanatory diagram for explaining a second solution means that is assumed in solving the problem in information development in the current fire and emergency activities. Further, FIG. 14 is an explanatory diagram for explaining an example of a solving means implemented in the present embodiment in order to solve a problem in information development in the current fire and emergency activities.

The first solution shown in FIG. 12 is to use the fire fighting system by replacing the call system between the current mobile phone and the fire fighting digital wireless communication system between the fire department headquarters (fire department) and the local fire brigade. The frequency of the digital radio is also the frequency dedicated to the call with the fire brigade. For the fire brigade related to Case A, the third fire radio wave (frequency for the third fire radio line) and for the fire brigade related to Case B are used. The fourth fire-fighting radio wave (frequency for the fourth fire-fighting radio line) is allocated to each of the radio waves. The operation method in the case of FIG. 12 is almost the same as the current operation method, but the features are as follows.

Two-way voice calls between the fire station headquarters (fire department) command board and each fire station digital radio transceiver (radio) can be transmitted and received only under the same radio frequency, so the fire department headquarters Information transmission (information development) from the (fire department) to the fire brigade members related to case A and the fire brigade members related to case B can be performed manually by the verbal commander of the fire department (fire department). is necessary. In addition, the total amount of frequencies used for the digital fire fighting radio will be double that of the current situation. That is, as shown in FIG. 12, the total number of radio waves is twice the number of active waves.

Next, the second solution shown in FIG. 13 is to replace the communication means between the fire department headquarters (fire department) and the local fire brigade with a digital fire radio from the mobile phone, and as the communication means, each disaster case. To the fire brigade related to the above, the frequency for the fire fighting digital radio, which is the activity wave used by firefighters engaged in fire fighting activities in each disaster case for fire and emergency activities, is allocated. The features of the case of FIG. 13 are as follows.

It becomes possible for the fire brigade member associated with each disaster case to directly hear the voice information between the firefighter who is engaged in the fire and emergency activities of the respective disaster case and the commander of the fire department headquarters (fire department). However, even the voice information of the fire brigade member, which is transmitted by pressing the call button of the fire brigade digital radio transmission/reception terminal (radio machine) used by the fire brigade member, is in a state of being heard by the firefighter during the fire and emergency activities. Therefore, it may affect the fire and emergency activities of firefighters who are active in the field. In addition, in the case of FIG. 13, since the frequency for the fire fighting digital radio used by the firefighters in each disaster case is also used for the fire brigade, the total amount of the frequency for the fire fighting digital radio used is the current case. Is the same. That is, as shown in FIG. 13, the total number of radio waves is the same as the number of active waves.

Next, FIG. 14 shows an example of the solving means described as the embodiment of the present invention, and has the following features.

In the present embodiment, audio information of the first fire fighting radio wave (frequency for the first fire fighting radio line) and the second fire fighting radio wave (frequency for the second fire fighting radio line), which are activity waves used for fire fighting activities, that is, All the audio information of the fire fighting digital radio frequency for each disaster case is mixed and generated as information sharing audio information. Then, the generated information sharing voice information is transmitted to the fire brigade related to each disaster case by using a predetermined radio frequency (information sharing firefighting radio wave) as an information sharing frequency. Therefore, by using the frequency of the fire fighting digital radio corresponding to the information sharing frequency in the fire fighting digital radio transmitting/receiving terminal (radio device) of each fire brigade member associated with each disaster case, the information sharing voice information (first fire fighting) It is possible to automatically listen to all the voice information for fire fighting activities using the radio wave and the second fire fighting radio wave.

Furthermore, even in the case of a digital fire transmitter/receiver terminal (radio device) of a firefighter who is engaged in fire fighting activities in each disaster case, if the frequency for information sharing is used, the voice information for information sharing is automatically heard. be able to. In addition, the information sharing voice information using the information sharing radio wave (information sharing frequency) is leaked to the first fire fighting radio wave and the second fire fighting radio wave that handle the voice information for fire fighting activities for each disaster case. It can be completely prevented.

In addition, the dispatcher of the fire department (fire department) should specify only the voice information between the firefighter and the commander corresponding to the disaster case or disaster point that the fire brigade member wants to hear, and have the relevant fire brigade member hear it. Is also possible. In addition, the voice information of the fire brigade member transmitted by pressing the call button of the fire brigade digital radio transmission/reception terminal (radio machine) of the fire brigade member can be heard only by the fire brigade member and the dispatcher of the fire department headquarters, It is not heard by firefighters who are active in the field.

In the case of FIG. 14, the total amount of frequencies used for fire fighting radio is at least one more than in the current case because an information sharing frequency for transmitting and receiving information sharing voice information is required. That is, as shown in FIG. 14, the total number of radio waves is a number obtained by adding at least “+1” to the number of active waves. Further, the number of frequencies for information sharing can be set to an arbitrary number of 1 or more as necessary, as described above.

The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such an embodiment is merely an example of the present invention and does not limit the present invention in any way. Those skilled in the art can easily understand that various modifications and changes can be made according to a specific application without departing from the scope of the present invention.
