Abstract
PURPOSE:To improve the possibility of connection of a communication line by deciding a time zone called again based on a random number if the communication line cannot be connected because plural terminal equipments are going to send one and same emergency signal to a management center. CONSTITUTION:A preset consumption signal Ae is sent from a terminal equipment A for automatic metering system at a time t1 and received by a management center. Terminal equipments A-C are going to send the emergency signals As-Cs of the highest emergency at a time t2 but the time reaching the management center is deviated slightly respectively due to the difference from the connection operation time and only the signal Bs of the terminal equipment B reaching fastest is received by the management center. In this case, the terminal equipments A, C not connected generate a random number in their insides and the terminal equipment, e.g., A is controlled to send a signal at a time t4 and the equipment C at time t6 based thereupon. The operation above is executed by a microcomputer provided in the terminal equipment as a transmission control means.
