Description

  The present invention can immediately confirm the location of disaster occurrence and the status of transition in the event of a disaster such as a gas leak or fire, and promptly and reliably report the disaster information to the relevant organizations, thereby achieving early suppression. It is about disaster prevention support system.

  Conventionally, disaster detection terminals such as gas leak detectors and fire detectors have been installed to detect disasters caused by gas leaks or fires in buildings and facilities such as buildings. The alarm output of the disaster prevention terminal is generally a contact output by a relay, and the relay contact output is connected in parallel for each system and input to a monitoring device to perform monitoring for each system.

  For example, FIG. 2 is an example of a wiring system between a disaster prevention terminal and a monitoring device in a conventional disaster prevention support system. Disaster prevention terminals 4a and 4b are installed in rooms 2a and 2b in a building, respectively. The state where the disaster prevention terminals 4c, 4d, and 4e are installed is shown. Further, the relay contact outputs of the disaster prevention terminals 4a, 4b, 4c, 4d, and 4e are connected by the wiring 5a, and input to the monitoring device 8 as the A system. Similarly, another disaster prevention terminal (not shown) is connected by the wiring 5b. 2) are connected to the monitoring device 8 as a B system.

  Here, when a disaster occurs in the room 2a and the disaster prevention terminal 4a is activated and the relay contact is turned on, the monitoring device 8 turns on the indicator 9 corresponding to the A system disaster occurrence display to It is possible to notify the administrator that a disaster has occurred in the system, and to notify the occurrence of the disaster for each system separately from the other B systems.

In the “automatic fire alarm system” disclosed in Japanese Patent Application Laid-Open No. 07-147579, a relay interface connected to a disaster prevention terminal such as a fire detector and a receiver thereof are provided with a communication interface having a communication protocol function suitable for a computer LAN system. The system is configured to allow data transmission by the computer LAN communication method between the separately installed computer terminal and the receiver and between the receiver and the repeater. A fire alarm system is disclosed in which a transmission trunk line can be unified by a LAN such as 10BASE-T, and data can be obtained and controlled at a remote place. In recent years, there is a system in which disaster information acquisition and disaster suppression commands are centrally managed in a disaster monitoring center or the like by making the disaster prevention support system compatible with such a LAN network.

  However, in the conventional disaster prevention support system, the relay contact outputs of disaster prevention terminals such as gas leak detectors and fire detectors are connected in parallel, that is, ORed for each system and input to the monitoring device. By simply turning on the relay contact of one disaster prevention terminal, the entire system was turned on, and only monitoring for each system was possible. For this reason, the disaster prevention terminal that performed the alarm output cannot be specified, and there is a problem that a delay occurs in the initial response.

  In addition, when the conventional disaster prevention support system is compatible with a network such as a LAN, TCP / IP (Transmission Control Protocol / Internet Protocol) is the mainstream as a communication protocol, but the TCP / IP protocol control is performed by software control. Since it has been executed, it has been difficult to increase the communication speed. In addition, there has been a problem that data may be tampered with or wiretapped or the system may be down due to unauthorized access by a hacker or transmission of a virus.

  The present invention has been made in order to solve the above-described problems. When a disaster occurs, it is possible to immediately identify the location and transition state of the disaster occurrence, and further increase the speed of TCP / IP protocol control. Providing a disaster prevention support system that can quickly and reliably report related disaster information to relevant organizations by speeding up the information transmission associated with it and performing robust network control against unauthorized access and viruses. The purpose is to do.

  In order to solve the above problems, in the disaster prevention support system of the present invention, the relay contact outputs of disaster prevention terminals such as gas leak detectors and fire detectors are individually input to the control device, and OSI basic reference is given to the control device. Built-in TCP / IP control unit with built-in data link layer of model second layer, network layer of OSI basic reference model third layer and transport layer of OSI basic reference model fourth layer in network such as LAN TCP / IP protocol control is executed by hardware control.

  In addition, a monitoring server is connected to a network such as the LAN, and a network such as the Internet to which a network communication terminal mounted on a server installed in a related organization such as a disaster monitoring center or a fire department or a disaster command vehicle is connected. Connect to.

  If the disaster prevention support system of the present invention is adopted in buildings and facilities such as buildings, it is possible to immediately confirm the location of disaster occurrence and the transition status at the time of disaster occurrence, without causing a delay in the initial response of disaster suppression, There is an effect that it is possible to respond quickly. In addition, since the TCP / IP protocol control is executed by the hardware control in the control device, high-speed communication can be performed with a constant and high latency, and there is no damage caused by unauthorized access by a hacker or virus transmission. . For this reason, there is a great effect that disaster information can be promptly and surely reported to the related organizations, and early suppression can be achieved.

  The best mode for carrying out the present invention will be described with reference to the drawings.
