Abstract: A transmission data synchronization system in a disaster prevention monitoring system comprises the steps of: connecting a plurality of terminal units to first and second transmission lines led out from a receiver; sending out access data in the form of a voltage from the receiver through the first transmission line; and sending back response data by a terminal unit specified in the access data in the form of an electric current through the second transmission line during a response time period. The response data sent back by a terminal unit which has responded to the access data sent out by the receiver is formed of terminal state data and checksum data produced by adding the terminal state data to the self-address data. The receiver adds the address data to the terminal state data, and determines that a transmission error has occurred when the data determined from the addition does not match the checksum data.

Abstract: During data transmission between a receiver and each of terminal devices in a disaster prevention supervisory system, the receiver sends calling data including address data for specifying a specific terminal device to the side of terminal devices in a transmission error detection mode. The receiver also causes the terminal device specified by the address data to return error detection response data including self-address data and check data for a current level previously defined. When the current level of the check data in the error detection response data received by the receiver is higher than the level previously defined due to the response of a plurality of terminal devices, it is decided that an abnormality is present in the terminal device of the address specified by the calling data.

Abstract: A terminal of a disaster prevention monitor of the present invention detects the power-on of a terminal and sets flag information. When a polling call from a central monitor (receiver) is directed to a terminal after a power-on operation, the terminal transmits an information fetch request signal which requests the receiver enter an initialization routine for initialization of the terminal information. The receiver transmits an information request command signal to the terminal. The terminal transmits information to the receiver identifying the type of terminal which is responding. Depending on the type of terminal, the receiver may command test operations at the terminal and obtain the test results therefrom in order to generate and store proper initialization information about the terminal.

Abstract: An anti-disaster system for receiving terminal data in response to the sequential calling of the terminals which is achieved by designating addresses from a receiver and for performing alarming or the like. Each of the terminals has an interrupt transmission section for transmitting a break signal which invalidates a terminal response signal on a timing when the terminal response signal to the receiver is transmitted when an abnormality is detected to notify generation of an interrupt.

Abstract: Disclosed is an anti-disaster system in which terminals are called by the polling system and in which the response signals from the terminals are received and decoded by a receiver to issue an alarming. Each of the terminals has an interrupt transmission section for transmitting an interrupt signal at a predetermined time during the receiver's transmission of the calling signal when an abnormality is detected. The receiver has an interrupt detection section for monitoring the predetermined time during the transmission of the calling signal to detect an interrupt signal from the terminal, and a calling control means for sequentially performing terminal group calling when the interrupt detection output is obtained from said interrupt signal detection section to specify the terminal in which abnormality data is detected.
