Centralized supervisory terminal of suffering supply body

摘要

Abstract Topic There is no wire telephone circuit, or laying the wire circuitEven in user of difficult suffering supply body centralized supervisory sir of suffering supply bodyOffering the centralized supervisory terminal whose offer of bis is possible. Solutions As for gas centralized supervisory terminal 12, user of gasIt is installed in 16, concentrating the status of the gas which is supplied to user 16Through public network 18 to the supervisory center 10 which, you monitor joint possibilitySo it is. As for centralized supervisory terminal 12, specification from of supervisory center 10Application/response moving, information concerning the use of the gas in user 16It delivers and receives with supervisory center 10. Centralized surveillance intelligence circuit 30In supply system it is jointed 22 of the gas in user 16 and 24,The signal which shows the amount used of the gas is incorporated. As for transmitter-receiver circuit 32,PHS radio wave of public network 18 sending and receiving is done. Identification information containment timeAs for path 36, the identification code, and the terminal which identify user 16Containment the device of machine 14 and the identification code which identifies positionru. When the transmitter-receiver circuit 32 receives the specification from of center 10,According to this specification as for system control section 46, the centralized surveillance intelligence timeYou read the amount used of the gas from path, 30 controlling the transmitter-receiver circuit 32Doing, the information which shows amount used with information of the above-mentioned two identificationsAddressing to supervisory center 10, it makes transmit.
