Hereinafter, the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram showing a command system 100 according to this embodiment. The solid line in the figure indicates the flow of power, and the arrow indicates the flow of data.

  The command system 100 includes, as main blocks, a data control device 110 that performs data communication and data control, a line control device 120 that controls notification from a dedicated radio or general line, and a command stand 130 that controls these. . The data control device 110 is supplied with power from the first power supply 141 connected to the commercial power supply 140, and the line control device 120 and the command board 130 are supplied with power from the second power supply 142. The reason why the power sources are separated in this way is to maintain a control function by voice communication as a last fort in an emergency such as a power failure. Note that alternating current and direct current may be used separately, such as the first power supply 141 being an AC power supply and the second power supply 142 being a DC power supply.

  The data control device 110 is connected to a general data communication network 161 such as the Internet, and transmits / receives data to / from an external device. The external device is, for example, a mobile in-vehicle terminal, a communication facility such as a fire department or a police station, or a portable terminal held by a member.

  The line control device 120 is connected to a dedicated wireless 162, a wired dedicated line 163, and a general line 164. The line communication control device 120 performs processing such as line switching so that voice communication between the command board 130 and the outside, reception of a report via the ISDN line, and the like are appropriately performed.

  The line control device 120 has a storage unit 121 and holds a part of data transmitted from the data control device 110 to the command board. If this data is, for example, backup data that is periodically overwritten, the capacity of the storage unit 121 can be reduced.

  The line control device 120 has a data control device monitoring unit 122. The data control device monitoring unit 122 monitors the operation of the data control device 110 by a monitoring signal or the like, and detects when the data control device 110 becomes inoperable.

  Further, the line control device 120 has communication method switching means 123. The communication method switching means 123 has a function of switching the data communication path from the data communication network 161 to the dedicated radio 162 when the data control device 110 becomes inoperable.

  The command stand 130 is connected to the data control device 110 and the line control device 120, and is an apparatus for an operator to perform control operations such as data browsing, telephone calls, and commands.

  In addition, the command system 100 according to the present embodiment is provided with an emergency data control device 150 that is connected to the line control device 120 and the command board 130 and is normally suspended. The emergency data control device 150 controls the data sent via the dedicated radio 162 when the data control device 110 is stopped, and substitutes the function of the data control device 110. A part of the function to be replaced may be used. The emergency data control device 150 is supplied with power from the second power source 142. A broken line in FIG. 1 indicates a data flow when the emergency data control device 150 is used. In this case, the data transmitted via the dedicated radio 162 and received by the line control device 120 is transmitted to the emergency data control device 150, appropriately processed, and sent to the command board 130.

  Since the emergency data control device 150 is emergency, it is possible to keep only the minimum necessary functions among the functions of the data control device 110, to select a function to be operated, or to reduce the processing speed even with the same function. For example, it may be possible to operate with less power than the data control device 110.

  Next, the operation of the command system 100 when the data control device 110, which is a feature of the present embodiment, becomes inoperable will be described.

  At normal times, data such as vehicle dynamics and position information is sent to the command board 130 by the data control device 110. Here, it is assumed that the data control device 110 becomes inoperable. At this time, the line communication control device 120 activates the emergency data control device 150 and switches to perform data communication with the dedicated radio 162. This maintains data communication and data processing functions.

  FIG. 2 is a sequence diagram showing this operation. First, the line control device 120 detects that the data control device 110 has become inoperable (s1). Next, the line control device 120 transmits an instruction to switch to wireless data communication using the dedicated wireless 162 to the external device 200 of the communication partner (s2). This instruction is performed, for example, by transmitting a predetermined signal. Further, the line controller device 120 performs switching to wireless data communication (s3). Next, the line control device 120 transmits an activation request for the emergency data control device 150 and activates the emergency data control device 150 (s4). When the activation is completed, the emergency data control device 150 transmits a report that the activation has been completed to the line control device 120 (s5). Next, the line control device 120 transmits the data stored in the storage unit 121 to the emergency data control device (s6). The emergency data control device 150 appropriately processes the received data (s7), and transmits the processed data to the command board 130 (s8). The command board 130 displays the received data (s9). When wireless data communication is possible, the line control device 120 requests the external device 200 to transmit data (s10). On the other hand, the external device 200 transmits data using the dedicated radio 162 (s11). Next, the line control device 120 transmits the received data to the emergency data control device 150 (s12). The emergency data controller 150 appropriately processes this data (s13) and transmits it to the command board 130 (s14). The command board 130 displays the received data (s15). As described above, data communication can be performed by the dedicated radio 162, data processing can be performed by the emergency data control device 150, and the data can be displayed on the command board 130. In the above description, an example in which data is received from the external device 200 has been described. However, data can be transmitted to the external device 200 by the same procedure.

  Next, as a specific example of the command center 100, the details of the apparatus will be described with respect to the high-function fire command center.

  As shown in FIG. 3, the data control device 110 includes a dispatch vehicle operation management device 111, an automatic dispatch specification device 112, a map search device 113, a support information search device 114, a weather information collection device 115, and the like. The dispatch vehicle operation management device 111 is a device that automatically selects an ambulance or fire truck vehicle nearest to the disaster site based on the disaster situation, and automatically organizes an optimal unit capable of responding to the disaster. Reference numeral 112 denotes an apparatus that performs search and determination of a disaster place, selection of a dispatched vehicle, dispatch command by synthesized voice, management of a disaster case, and the like.

  As shown in FIG. 4, the line control device 120 includes a storage unit 121, a data control device monitoring unit 122, a communication method switching unit 123, a command control device 124, a mobile phone / IP telephone transfer device 125, a voice synthesis device 126, a long A time recording device 127 and the like. The command control device 122 is a device for receiving a command line 119 and giving commands to each station when a disaster occurs. The voice synthesizer 124 is a device that automatically synthesizes a message with a combination of recorded words when receiving No. 119, and performs command broadcasting / disaster situation guidance.

  As shown in FIG. 5, the command board 130 includes a display unit 131, a voice input / output unit 132, an input / output device 133, and the like. The display unit 131 is a device that displays each piece of information sent from the data control device 110. The input / output device 133 is, for example, a keyboard or a printer.

  Although not shown, the high-function fire command center 100 includes a display panel. The display board includes a vehicle operation display board, a support information display board, and a multipurpose display device.

  In the high-function fire command center as described above, this embodiment is particularly effectively applied.

(Second Embodiment)
FIG. 6 is a block diagram showing a second embodiment of the present invention. The command system 100 according to the present embodiment includes a UPS 143 (uninterruptible power supply) serving as a backup power source and a private power generation device 144. Further, it has a supply destination switching means 145 for switching where the electric power supplied from the UPS and the private power generator 144 is supplied.

  Since the commercial power supply 140 can be used during normal times, the supply destination switching means 145 is kept disconnected from both the first power supply 141 and the second power supply 142.

  When the commercial power supply 140 cannot be used due to a power failure due to a disaster, two modes can be selected. One is a mode in which power is supplied to both the first power supply 141 and the second power supply 142. This mode is selected when the capacity of the UPS 143 or the power generation amount of the private power generation device 144 has a surplus. In this case, as a matter of course, the command system 100 can perform the business as usual.

  The other is a mode in which power is supplied only to the second power source 142. In this case, the data control device 110 is stopped and the line control device 120 is operated, and the data communication is switched from communication via the data communication network 161 to communication via the dedicated radio 162. The operation of the apparatus at this time is the same as that of the first embodiment. As described in the first embodiment, if the emergency data control device 150 is operated with less power than the data control device 110, it is possible to save power by selecting this mode. .

  Which mode is to be selected may be switched automatically by the line control device 120 referring to the fuel remaining amount of the private power generation device 144, or may be selected by the command board 130. You can leave it.

FIG. 7 is a flowchart showing the operation of the command system 100 at this time.
First, the supply of commercial power stops due to a disaster or the like. Due to a power failure, the original power source is switched from the commercial power source 140 to a backup power source such as the UPS 143 and the private power generator 144 (s101). Next, the line control device 120 estimates the supply capacity of the backup power supplied from the backup power source, and determines whether the backup power has a capacity (s102). If there is remaining power, power is supplied to both the first power supply 141 and the second power supply 142 to operate the command system (s102_Yes). When there is no reserve power (s102_No), power is supplied only to the second power source 142 (s103). Next, the data communication is switched to the dedicated radio 162 (104). Here, it is further determined whether or not there is a reserve power (s105). If there is a reserve power, the emergency data control device 150 is fully operated (s105_Yes). If the remaining power is not sufficient, the emergency data control device 150 is operated in the power saving mode in which the function to be operated is reduced or the processing speed is reduced (s105_No).

As described above, when this embodiment is applied, data communication and data processing functions can be maintained in an emergency such as a power failure with less power than normal.
