(Mobile phone terminal)
A mobile terminal used in the disaster prevention monitoring management system is a mobile phone terminal having a call function.

(Basic effect)
The disaster prevention monitoring facility management system of the present invention is provided in one or a plurality of disaster prevention facilities, and includes a receiver that receives a fire signal from a fire detector installed in a monitoring area and gives an alarm, and a control unit provided in the receiver. A wireless communication adapter that connects to an input / output port and communicates with an external device via a wireless line, and if the wireless communication adapter is in a communicable area, the wireless communication adapter is connected to the external communication network. In addition, a mobile terminal for communication connection with the external communication network and a server for communication connection with the mobile terminal via the external communication network are provided, and the wireless communication adapter, the mobile terminal, and the external communication network are connected between the receiver and the server. For example, a facility that functions as a wireless LAN access point owned by a manager or person in charge of the facility is configured to transmit and receive predetermined data between the receiver and the server. When a mobile terminal such as a mobile phone enters a communication area of a wireless communication adapter provided in the receiver, for example, a wireless LAN adapter, external communication including a wireless LAN adapter, a mobile terminal, a mobile phone network, and the Internet between the receiver and the server. A communication connection is made via the network, and at this time, based on a request from the receiver side or the server side, it becomes possible to upload necessary data from the receiver to the server or download from the server to the receiver. The data can be collected at the manufacturing side that owns the disaster prevention monitoring equipment, and the receiver side can receive support services from the server as needed.

  The communication connection between the receiver and the server is a wireless communication adapter that functions as a wireless LAN station for the receiver, for example, a small and inexpensive wireless LAN adapter known as a WiFi dongle as an input / output port of the receiver controller. It can be realized by connecting to a functioning USB port and using the access point function of the mobile terminal owned by the administrator or person in charge who goes in and out of the equipment receiver installation location, and the additional device is a wireless LAN adapter After that, you can easily connect to the Internet using the access point function of your mobile device.

  In addition, when connecting to the Internet using the access point function of a mobile terminal owned by an administrator or person in charge who enters or exits the equipment receiver installation location, if the administrator or person in charge is absent, the mobile terminal However, if you look at a period such as one day or one week, there is always an opportunity for the mobile terminal to be in the communication area of the wireless communication adapter provided in the receiver, and use that timing to connect to the Internet As a result, a necessary and sufficient communication connection can be realized between a server and a receiver that do not exchange data very frequently.

(Effects of collecting historical data)
In addition, the control unit of the receiver stores a predetermined event generated during the monitoring control as history data, and a communication connection between the wireless communication adapter and the portable terminal is established every time a predetermined inquiry cycle is reached. When the inquiry signal is received from the receiver, the control unit of the server transmits the history request signal to the receiver and receives it when the predetermined history collection period has been reached. When the control unit of the machine receives a history request signal from the server, it transmits history data for a predetermined period to the server, and the server control unit stores the history data received from the receiver. The communication connection between the communication adapter connected to the machine and the mobile terminal occurs randomly depending on the behavior of the manager or person in charge at the facility that owns the mobile terminal. The server that has received the inquiry collects history data by making a history request to the receiver if, for example, the one month history collection cycle has been reached, and notifies the end of communication, for example, if the history collection cycle has not been reached, Even if the communication connection between the receiver and the server is randomly generated, the history data for a predetermined period can be sent from the receiver to the server by using the opportunity.

(Effect of interruption and resumption of history data transmission)
In addition, when receiving a history request signal from the server, the control unit of the receiver divides the history data for a predetermined period to be transmitted into block data of a predetermined data length, and sequentially transmits the block data while the block data is being transmitted. When the communication connection between the wireless communication adapter and the portable terminal is interrupted, the block data where the data transmission is interrupted is stored, and when the communication connection between the wireless communication adapter and the portable terminal is established, the data transmission is performed. Because the transmission was resumed from the beginning of the interrupted block data, the communication connection between the receiver and the server using the mobile terminal was moved away from the receiver installation location by the administrator or person in charge holding the mobile terminal. In some cases, there is a possibility of interruption at random, but assuming that this data transmission is interrupted, history data is divided into block data and transmitted sequentially, and data transmission is interrupted. If the next communication connection is made, it is not necessary to resend the history data from the beginning by resuming transmission from the beginning of the block data where data transmission was suspended, and even if data transmission is interrupted and resumed, It is possible to transmit history data efficiently.

(Effect of program update)
The control unit of the receiver transmits an inquiry signal to the server on the condition that the communication connection between the wireless communication adapter and the portable terminal is established every time a predetermined inquiry cycle is reached. When the inquiry signal is received from the receiver, a predetermined program update signal is transmitted to the receiver, and when the program control signal is received, the control unit of the receiver executes its own program based on the program update signal. Since it was updated, the communication connection between the communication adapter connected to the receiver and the mobile terminal is the same as in the case of history data transmission from the receiver to the server. This occurs randomly depending on the behavior of the receiver.At this time, the server makes an inquiry to the server, and the server that has received the inquiry updates the update program if the receiver program update is set. Upgraded by sending a lamb to the receiver, communication connection between the receiver and the server even as occurred at random and from the receiver the update program by utilizing the opportunities and possible update to send to the server.

(Effect of interruption and resumption of update program transmission)
In addition, when transmitting a program update signal to the receiver, the control unit of the server divides the update program to be transmitted into block data of a predetermined data length and sequentially transmits the program to the mobile terminal during transmission of the block data. When the communication connection between the wireless communication adapters is interrupted, the block data where the data transmission is interrupted is stored, and when the communication connection between the mobile terminal and the wireless communication adapter is established, the block data of which the data transmission is interrupted is stored. Since the transmission is restarted from the beginning, the communication connection between the receiver and the server using the portable terminal is installed by the administrator or the person in charge who owns the portable terminal as in the case of history data transmission. There is a possibility that it will be interrupted randomly when it is away from the place, but assuming that this data transmission is interrupted, the update program is divided into block data and sent sequentially If the data transmission is interrupted and the next communication connection is made, it is not necessary to restart the transmission of the update program from the beginning by restarting the transmission from the beginning of the block data for which the data transmission was interrupted. Even if the transmission is interrupted and resumed, the update program can be transmitted efficiently.

In the fire monitoring control, a fire alarm is output by receiving a fire signal generated by a fire detector or a fire signal generated by operating a transmitter.

  If it is determined in S3 that a predetermined inquiry period of, for example, 1 hour is reached in S3 during the fire monitoring control in the fire monitoring mode, the process proceeds to S4, and it is determined whether or not wireless LAN communication with the mobile phone terminal 14 by the wireless LAN adapter 12 is possible. . If the mobile phone terminal 14 is present in the communication area of the wireless LAN adapter 12 at this time, it is determined in S3 that wireless LAN communication is possible, the process proceeds to S5, and an inquiry signal is transmitted to the server 24 to make an inquiry.

  Subsequently, when there is a response from the server 24 in S6, the process proceeds to S7, and when the history data request is determined by receiving the history request signal, the process proceeds to S8, and the history data for a predetermined period, for example, one month, has a predetermined data length. The history data signal divided into blocks is sequentially transmitted to the server 24. If the end of data transmission is determined in S9 during transmission of this history data signal, the process returns to S2 to perform fire monitoring control in the fire monitoring mode.

  If the wireless LAN communication is determined to be interrupted at S10 until the end of data transmission is determined at S9, the process proceeds to S11 to store the interrupted block, and if it is determined that wireless LAN communication is possible at S12, the process proceeds to S13. The transmission of the history data signal is resumed from the beginning of the interrupted block.

  On the other hand, if it is determined in S7 that the request signal from the server 24 is not a history request, the process proceeds to S14, and if a communication end request due to reception of the communication end request signal is determined, the process returns to S2. If it is not a communication end request in S14, the process proceeds to S15, and necessary processes for other requests are performed, and the process returns to S2.

  When a program update request signal is received from the server 10 in response to an inquiry from the receiver 10, the program of the control unit 11 of the receiver 10 is updated when reception of the program update signal sequentially transmitted by block division is completed. FIG. 5 is a flowchart of the control for storing the block received from the beginning of the interrupted block when the reception of the program update signal is interrupted and storing the interrupted block and when the data reception is resumed. Will join.

Server control
FIG. 6 is a flowchart showing server control taking the reception of history data as an example, and is controlled by the control unit 26 provided in the server 24 of FIG.

  As shown in FIG. 6, after performing a predetermined initialization process upon power-on in S21, if it is determined in S22 that there is an inquiry due to reception of an inquiry signal from the receiver 10, the process proceeds to S23, for example, with a period of one month. When the history data collection timing after noon on the first day of the month is determined, a history data request is made by transmitting a history request signal to the receiver 10 in S24.

  Subsequently, when the transmission response of the history data signal from the receiver 10 is determined in S25, the history data signal is received and stored in block units in S26. If the end of data reception is determined in S27 during reception of the history data signal, the process returns to S22 to perform fire monitoring control in the fire monitoring mode.

  If it is determined in S27 that the data transmission has been terminated before determining the end of data transmission, the process proceeds to S29 to store the interrupted block. History data from the head of the block is received and stored.

  On the other hand, if it is determined in S23 that it is not the history data collection timing, the process proceeds to S32, a communication end request signal is transmitted to the receiver 10, and the process returns to S22.

  When an update program is prepared on the server 24 side for reception of the inquiry signal from the receiver 10, the program update signal divided into blocks of a predetermined data length is sequentially transmitted to the receiver 10, and the data transmission is interrupted. In this case, the interrupted block is stored, and when the communication connection is resumed, control for resuming transmission from the head of the interrupted block is added to the flowchart of FIG.
