Description

[Technical Field]

[0001] The present invention relates to a terminal, a command system, a command instruction transmission method, and a program. [Background technology]

[0002] In the field of firefighting and the like, a command system is known in which a command device that receives emergency calls from citizens and sends instructions to terminals at various locations is connected to a station terminal that receives instructions from the command device. For example, Patent Document 1 discloses a portable command device that can continue to operate at a location where a regular telephone line is available when a situation occurs in which infrastructure facilities such as power supply and communications are unavailable at the location where the command device is installed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-69030 Summary of the Invention [Problem to be solved by the invention]

[0004] In addition to the loss of power sources and communication infrastructure as envisioned in Patent Document 1, it is also anticipated that restrictions on access to buildings where command devices are installed or areas where such buildings are installed will make it difficult to continue command operations. In such cases, the command device of Patent Document 1 can be used, but there is a problem in that it takes time to resume operations because it takes time to move and install the command device.

[0005] The present disclosure aims to provide a terminal, a command system, and a method for transmitting command instructions that can increase the continuity of command operations in situations where access to a building in which a command device is installed or an area in which the building is installed is restricted. [Means for solving the problem]

[0006] According to a first aspect, a terminal is provided that can switch between a first operating mode in which it receives command instructions from a command device that accepts emergency calls and performs predetermined output processing, and a second operating mode in which it can accept emergency calls on behalf of the command device and send command instructions to other terminals.

[0007] According to a second aspect, a command system is provided that includes a terminal that can switch between a first operating mode in which it receives command instructions from a command device that accepts emergency calls and performs predetermined output processing, and a second operating mode in which it can accept emergency calls on behalf of the command device and send command instructions to other terminals, and the command device.

[0008] According to a third aspect, a method for transmitting command instructions is provided in which a terminal capable of switching between a first operating mode in which it receives command instructions from a command device that accepts emergency calls and performs predetermined output processing, and a second operating mode in which it can accept emergency calls on behalf of the command device and send command instructions to other terminals, switches from the first operating mode to the second operating mode when the command device becomes unable to send command instructions, accepts emergency calls on behalf of the command device, and sends command instructions to the other terminals.

[0009] According to a fourth aspect, a program is provided for causing a computer capable of switching between a first operating mode in which a command instruction is received from a command device that accepts emergency calls and performs predetermined output processing, and a second operating mode in which the computer can accept emergency calls and send command instructions to other terminals on behalf of the command device, to execute a process of switching from the first operating mode to the second operating mode when the command device is unable to send command instructions, and a process of accepting emergency calls and sending command instructions to the other terminals on behalf of the command device. [Effects of the Invention]

[0010] According to the present disclosure, it is possible to increase the continuity of command operations in situations where access to the building in which the command device is installed or the area in which the building is installed is restricted. [Brief explanation of the drawings]

[0012] First, an overview of one embodiment of the present disclosure will be described with reference to the drawings. Note that the reference numerals in this overview are added to each element for convenience as an example to facilitate understanding, and are not intended to limit the present disclosure to the illustrated form. Furthermore, connecting lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows are used to schematically indicate the flow of main signals (data) and do not exclude bidirectionality. A program is executed via a computer device, which includes, for example, a processor, a storage device, an input device, a communication interface, and, if necessary, a display device. Furthermore, this computer device is configured to be able to communicate with internal or external devices (including computers) via the communication interface, whether wired or wireless. Furthermore, ports or interfaces are present at the input / output connection points of each block in the drawings, but are not shown.

[0013] In one embodiment, the present disclosure can be realized in a command system including terminals 10a and 10b and a command device 20, as shown in FIG. 1. More specifically, the terminals 10a and 10b are switchable between a first operation mode and a second operation mode. The first operation mode is an operation mode in which the terminals 10a and 10b receive a command instruction from the command device 20, which accepts an emergency call, and perform a predetermined output process. The second operation mode is an operation mode in which the terminals 10a and 10b can accept an emergency call and transmit a command instruction to another terminal on behalf of the command device 20. In the following description, it is assumed that the command device 20 can instruct the terminals 10a and 10b to switch between the first operation mode and the second operation mode.

[0014] When the command device 20 receives an emergency call such as 119, it selects either or both of the terminals 10a and 10b and transmits a command instruction to them. In the example of FIG. 2, the command device 20 selects the terminal 10a and transmits the command instruction to it (see "Emergency Call" and "Command Instruction" in FIG. 2). The terminal 10a operating in the first operation mode performs a predetermined output process based on the command instruction received from the command device 20 (see "Predetermined Output" in FIG. 2). Examples of this output process include amplifying the command instruction (command amplification) and carrying out the command instruction (dispatch instruction to subordinate emergency vehicles).

[0015] On the other hand, as shown in Fig. 3, if the building in which the command device 20 is located is damaged, the command device 20 selects either the terminal 10a or 10b and transmits an operation mode switching instruction to it. In the example of Fig. 3, the command device 20 selects the terminal 10a and transmits the operation mode switching instruction to it (see "Operation Mode Switching Instruction" in Fig. 3).

[0016] The terminal 10a that has received the operation mode switching instruction operates in the second operation mode thereafter. Specifically, the terminal 10a starts accepting emergency calls such as 119 instead of the command device 20 (see "Emergency Call" in FIG. 4). Then, the terminal 10a transmits an instruction to the terminal 10b (see "Instruction" in FIG. 4). The terminal 10b that has received the instruction performs predetermined output processing based on the instruction received from the terminal 10a (see "Predetermined Output" in FIG. 4). Note that, when operating in the second operation mode, if the content of the received emergency call is content that should be processed by the terminal 10a, the terminal 10a issues an instruction to itself and performs the predetermined processing. In this case, it is needless to say that there is no need to transmit an instruction to other terminals.

[0017] The command system operating as described above can improve the continuity of command operations even in situations where access to the building where the command device 20 is installed or the area where the building is installed is restricted. Furthermore, compared to the portable command device of Patent Document 1, the system eliminates the time required for transportation and installation, thereby shortening the time required to resume operations. In particular, in recent years, the jurisdiction of command devices has expanded due to the expansion of firefighting organizations (wider area expansion, joint operations, outsourcing, etc.). The present disclosure has the advantage of being able to utilize the expanded jurisdiction to select a terminal located far from the disaster area and continue operations. Note that, in the above description, both terminals 10a and 10b are described as being switchable between the first and second operating modes. However, it is not necessary for both terminals 10a and 10b to be switchable between the first and second operating modes. For example, if either terminal 10a or 10b is switchable between the first and second operating modes, command operations can be continued using that terminal.

[0018] [First embodiment] Next, an embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 5 is a diagram showing a first configuration in which the present disclosure is applied to a firefighting command system. Referring to Fig. 5, a configuration is shown in which a command center building 200 and stations A to C (100a to 100c) are connected via a wide area Ethernet network 400. Note that "station" is a term that collectively refers to fire stations or their branch offices that receive commands and instructions from the command center.

[0019] The command center building 200 is equipped with a command control device / GW 210 and multiple command consoles 220a, 220b, and is capable of receiving 119 calls from citizens 600 via an emergency line network 500. For ease of explanation, the example in Fig. 5 shows two command consoles 220a, 220b, but the number of command consoles is not limited to two. Furthermore, the command consoles 220a, 220b are equipped with PCs (personal computers) 230a, 230b, respectively, for performing automatic command processing.

[0020] The command control device / GW210 has a function of transferring an emergency call to the command consoles 220a and 220b (including the terminals 110a to 110c that have taken over as the command consoles 220a and 220b) when an emergency call arrives via the emergency line network 500. GW is an abbreviation for gateway.

[0021] The command consoles 220a and 220b are operated by a commander. For example, as shown in FIG. 6, when an emergency call is received, the commander at the command console 220a performs a reception operation ((1) 119 call to (3) 119 reception in FIG. 3). Then, the commander sends an automatic command to the terminals (hereinafter also referred to as "station terminals") 110a to 110c of the relevant stations according to the incident via the wide area Ethernet network 400 from the command control device / GW 210 by automatic command operation at the command console 220a and PC 230a. This causes personnel to be dispatched at each station. In addition, the command consoles 220a and 220b can send an instruction to switch to the simplified command console mode or the station terminal mode to specific terminals 110a to 110c. These command consoles 220a and 220b correspond to the command device 20 described above.

[0022] Stations A to C (100a to 100c) are respectively equipped with terminals 110a to 110c, telephones 120a to 120c, and command loudspeakers 130a to 130c. In the example of Fig. 6, a PC (personal computer) 140a is installed in station A and is connected to terminal 110a. In the example of Fig. 6, terminals 110a to 110c and telephones 120a to 120c are installed independently, but they may also be integrated.

[0023] The terminals 110a to 110c are connected to the following two types of lines. - Lines for normal command (command lines) · Line for receiving 119 calls (control line) In the following description, it is assumed that there are four command lines per terminal, but there is no limit to the number of command lines.

[0024] The terminals 110a to 110c are configured to have the following three functions using the above two types of lines. Fig. 7 is a functional block diagram showing the detailed configuration of the terminal 110a. Referring to Fig. 7, the terminal 110a has a command desk function unit 111a, a communication unit 112a, and a connection unit 113a.

[0025] The command console function unit 111a is a function that substitutes the equipment of the command center with the equipment on the station side, and realizes the function of the command center (command console) at the station (remotely).

[0026] The communication unit 112a is a function that realizes a communication function (receiving emergency calls and issuing commands) between the command control device / GW 210 and the terminal 110a.

[0027] The connection unit 113a connects to the command control device / GW 210 using the ID of a specific command console, and provides a function of impersonating the command console number of the command center.

[0028] By combining these functions, the terminal 110a can function as a pseudo command console. Note that the terminals 110b and 110c have the same configuration as the terminal 110a, and therefore their explanations will be omitted.

[0029] Furthermore, the terminals 110a to 110c have a "station terminal mode" in which the functions of the station terminal shown in Fig. 6 can be used, and a "simple command desk mode" in which the functions of the station terminal can be used as well as the pseudo command desk. This "station terminal mode" corresponds to the first operation mode described above, and the "simple command desk mode" corresponds to the second operation mode described above.

[0030] Figure 8 is an example of a screen displayed on the display device of terminals 110a to 110c operating in "station terminal mode." "Station 00000" in Figure 8 displays information about the station where terminal 110a to 110c is installed, and the vehicle display column displays the status (movement) of the vehicle at the corresponding station. This allows the operator of terminal 110a to 110c to check the status of the vehicles at the station under their jurisdiction. Note that the "Register" and "Clear" buttons on the right side of Figure 7 are used to update and register or erase the vehicle status (movement).

[0031] Next, the operation of the terminals 110a to 110c from switching from the "station terminal mode" to the "simplified command console mode" and then returning to the "station terminal mode" will be described in detail with reference to the drawings.

[0032] 9 is a sequence diagram showing the mode change operation of the first configuration of the present disclosure. The following explanation will be given by taking an example in which some kind of disruption occurs in the operation of the command console 220a or the command center building, and the operation mode of the terminal 110a is switched. Referring to FIG. 9, first, the command console 220a sends an instruction to the terminal 110a to change the mode to the simple command console mode (step S001).

[0033] Upon receiving the instruction to change the mode, the terminal 110a changes the operation mode to the simple command desk mode (step S002). Then, the terminal 110a transmits a mode change response to the command desk 220a notifying that the operation mode has been switched to the simple command desk mode (step S003).

[0034] Upon receiving the response to the mode change, the command console 220a transitions to the stop mode. After that, the command console 220a starts to stop 119 reception, stop command lines, and stop each operation input (step S004). After that, it is desirable that the command console 220a not accept any operations from outside except for the operation to recover from the stop mode, which will be described later.

[0035] Furthermore, the terminal 110a connects to the command control device / GW 210 using the ID of the command console 220a, and becomes the command console 220a (step S005).

[0036] After this, the terminal 110a in the simple command console mode provides the following three functions. (1) 119 reception function When an emergency call arrives, the operator of the terminal 110a can perform reception operations in place of the commander at the command console 220a. (2) Switching display screens The terminal 110a switches from the station terminal screen shown in FIG. 8 to the simplified command console mode screen shown in FIG. 10. On this screen, it is possible to switch between the command reception screen (left side) shown in FIG. 10 and the station terminal screen using the up and down arrow buttons AB. The operator of the terminal 110a switches between the command reception screen and the station terminal screen to check the status of vehicles at each station, etc., and perform tasks in place of the commander on the command console 220a. Furthermore, if an 119 call is received while the station terminal screen is displayed, the terminal 110a automatically transitions to the command reception screen (left screen in FIG. 10). Conversely, if a command addressed to the terminal 110a is received while the command reception screen is displayed, the terminal 110a automatically transitions to the station terminal screen (right screen in FIG. 10). (3)Manual command The terminal 110a accepts a manual command operation from an operator and sends a manual command (voice command) to the relevant station.

[0037] The "Command Reception" column on the command reception screen shown in Figure 10 displays the caller who dialed 119. The "119" button in Figure 10 is pressed to receive a call, and the "Command" button is pressed to issue a fire command.

[0038] Fig. 11 is a diagram for explaining the operation (in simple command console mode) of the first configuration of the present disclosure. As described above, when an emergency call is received, the operator of terminal 110a performs a reception operation ((1) 119 call to (3) 119 reception in Fig. 11). Then, when the operator of terminal 110a performs a manual command operation according to the content of the emergency call, terminal 110a transmits the manual command to terminals 110b and 110c of other stations via wide area Ethernet network 400. This enables personnel to be dispatched at each station.

[0039] The terminal 110a can transmit and receive commands to its own station even in the simple command console mode. In this case, the terminal 110a operates as a station terminal and issues commands to the station.

[0040] Thereafter, when the command console 220a becomes usable again, the commander at the command console 220a performs a recovery operation. Specifically, the command console 220a again transmits an instruction to change the mode to the station terminal mode to the terminal 110a (step S007 in FIG. 9). Upon receiving the instruction to change the mode to the station terminal mode, the terminal 110a transitions to the station terminal mode. Meanwhile, the command console 220a resumes accepting 119 calls, restores the command line, and resumes accepting each operational input (step S008).

[0041] As described above, according to this embodiment, even if some kind of operational disruption occurs at the command console 220a or the command center building, the terminal 110a can quickly take over the function of the command console 220a. Also, as described above, the terminal 110a operating in the simplified command console mode has the same functions as the command console 220a, and therefore can continue command and control operations without degradation.

[0042] As is clear from the above explanation, the configuration of the present disclosure can be configured by simply adding functions (application programs) to an existing command console and terminal, which significantly reduces implementation costs compared to the configuration disclosed in Patent Document 1 or the configuration that requires the installation of backup equipment.

[0043] In the above configuration, an automatic command can be sent by connecting from PC 140a of station A (100a) to PC 230a in the command center building. Fig. 12 is a sequence diagram showing additional operations for changing the mode and issuing an automatic command in the first configuration of the present disclosure.

[0044] The operations of steps S001 to S006 in Fig. 12 are the same as those described in Fig. 9, and therefore will not be described again. When issuing an automatic command, the operator of the terminal 110a uses the PC 140a to remotely connect to the PC 230a of the command desk 220a (step S108). This remote connection can be, for example, one provided as a remote desktop function prepared in various operating systems.

[0045] Thereafter, the operator of the terminal 110a can operate the PC 140a to issue automatic commands in the same manner as the command console 220a (step S109).

[0046] FIG. 13 is a diagram for explaining the operation of the first configuration of the present disclosure (in the simplified command console mode and automatic command). As in FIG. 11, when an emergency call is received, the operator of terminal 110a performs a reception operation ((1) 119 call to (3) 119 reception in FIG. 13). Then, when the operator of terminal 110a performs an automatic command operation on PC 140a according to the content of the emergency call, the automatic command can be transmitted to terminals 110b and 110c of other stations via wide area Ethernet network 400. This enables personnel to be dispatched at each station.

[0047] 14 is a sequence diagram showing the operation when the command desk 220a becomes available after that. The commander of the command desk 220a disconnects the remote connection of the PC 140a from the command desk 220a (step S110). The subsequent operations are the same as steps S007 and S008 in FIG. 11, so a description thereof will be omitted.

[0048] As described above, even in the first configuration, automatic commands can be sent by using the PC 140a.

[0049] [Second embodiment] In the first embodiment described above, an example has been given in which the terminal 110a is in the simple command desk mode, but it is also possible for a plurality of terminals to each act as a different command desk and issue commands.

[0050] Fig. 15 is a sequence diagram showing the mode change operation in the second configuration of the present disclosure. In the following explanation, an example will be given in which the terminal 110a switches to the command desk 220a, and the terminal 110b switches to the command desk 220b. Referring to Fig. 15, first, the command desk 220a / 220b transmits a mode change instruction to the simple command desk mode to the terminal 110a and the terminal 110b (step S001). Note that this mode change instruction may be sent collectively by either the command desk 220a or the command desk 220b to the terminals 110a and 110b.

[0051] The subsequent operations are the same as those in FIG. 11, except that in step S005, the terminals 110a and 110b connect to the command control device / GW 210 using the IDs of the command desks 220a and 220b, respectively, and become the command desks 220a and 220b (step S005).

[0052] After the terminals 110a and 110b are switched to the simplified command console mode, when an emergency call is received, the call is transferred to the terminals 110a and 110b as shown in Fig. 16. The operators of the terminals 110a and 110b can perform reception operations ((1) 119 call to (3) 119 reception in Fig. 16).

[0053] Figure 17 is a continuation of Figure 16. When either the operator of terminal 110a or terminal 110b issues a manual command in response to the contents of the emergency call, either terminal 110a or 110b transmits the manual command to terminal 110c of another station via wide area Ethernet network 400. This makes it possible to dispatch personnel from station C (100c).

[0054] As explained above, according to the second configuration, it is possible to continue operations by distributing the operations of multiple command desks to multiple stations. This type of configuration is suitable for cases where the number of personnel resources and the number of lines at each station are limited.

[0055] [Third embodiment] In the first embodiment described above, an example was given in which one telephone 120a is connected to one terminal 110a, but multiple telephones can also be connected to one terminal 110a. Figure 18 is a diagram showing a third configuration of the present disclosure. The difference from the first configuration shown in Figure 5 is that n telephones 121a to 12na are connected to the terminal 110a of station A (100a). If there are four command desk lines per terminal, n = 4, so four telephones can be connected. The other configurations are the same as those of the first configuration, so explanations will be omitted.

[0056] Fig. 19 is a diagram for explaining the operation (in simple command console mode) of the third configuration of the present disclosure. When multiple emergency calls arrive simultaneously, they are transferred to telephones 121a to 12na. Multiple operators at station A (100a) can perform reception operations using telephones 121a to 12na, respectively ((1) 119 call to (3) 119 reception in Fig. 19). The subsequent operations are the same as those in the first configuration, so a description thereof will be omitted.

[0057] In the first configuration, only one telephone is connected to each terminal, so only one 119 call line can be handled. In this configuration, four telephones are connected, so four 119 call lines can be handled per terminal.

[0058] Furthermore, with this configuration, there will be situations where one terminal will need to operate four lines simultaneously. To accommodate this, it is desirable to split the screen of the terminal 110a as shown in Fig. 20. This makes it possible to perform command operations for up to four command desks. Furthermore, if there are restrictions on the resolution and size of the display device of the terminal 110a, it is also possible to adopt a configuration in which the screen is expanded using a multi-display as shown in Fig. 21.

[0059] Even in a configuration where multiple command console screens are displayed, it is desirable to automatically transition to the command reception screen when an incoming 119 call is received, and to automatically transition to the station terminal screen when a command is received at the station. In this case, only one of the four screens will automatically transition. It is sufficient to make the transition to any of the four screens that is not receiving 119 calls or commands.

[0060] In the configuration of Figure 18, an example has been given in which n telephones 121a to 12na are connected to terminal 110a of station A (100a), but it goes without saying that multiple telephones may also be connected to terminals 110b and 110c of other stations in a similar manner.

[0061] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments can be made without departing from the basic technical concept of the present disclosure. For example, the network configuration, element configuration, and data representation format shown in each drawing are examples to aid in understanding the present disclosure, and are not limited to the configurations shown in these drawings.

[0062] For example, in the above-described embodiments, the terminal 110a transitions to the simplified command desk mode upon receiving a mode change instruction from the command desk 220a. However, this switching operation may be automated. For example, a configuration may be adopted in which, when the command desk is stopped, a stop signal is sent from the command desk or another device to the terminal 110a, and the terminal 110a detects this stop signal and switches the operating mode. Similarly, a configuration may be adopted in which, when the command desk is restored, a recovery signal is sent from the command desk or another device to the terminal 110a, and the terminal 110a detects this recovery signal and switches the operating mode.

[0063] It is also possible to employ a configuration in which the operation mode is switched by transmitting a mode switching request from the terminals 110a to 110c to the command control device / GW 210. This allows the terminals 110a to 110c to continue command operations even if the command console suddenly becomes inoperable.

[0064] (About hardware configuration) In each embodiment of the present disclosure, each component of each device represents a functional block. Some or all of the components of each device are realized by any combination of an information processing device 900 and a program, for example, as shown in FIG. 22. FIG. 22 is a block diagram showing an example of the hardware configuration of the information processing device 900 that realizes each component of each device.
