发明名称 LINE TERMINAL EQUIPMENT IN AUTOMATIC METER INSPECTING SYSTEM
摘要 PURPOSE:To reduce electric work cost by adopting a radio system for signal transmission/reception among many meters distributed in a wide range and a line terminal equipment. CONSTITUTION:At the time of receiving a radio signal for requesting the output of measured data of integrated flow rate from the line terminal equipment with a radio function, a meter 1 arranged on each demanded position to measure the integrated flow rate of fluid in each demanded position transmits radio data like electric waves from a radio set 2. At the time of receiving electric wave-like radio data from each meter 1, the terminal equipment 5 converts the radio data into a wired signal by a radio control part and transmits the wired signal to a line control part. The line control part converts the wired signal into a line signal to be transmitted through a line 4 and sends the line signal from an exchange 8 to a center meter inspector 12 in a meter inspection center through a gauge inspection center side line terminal equipment 10. The inspector 12 successively inputs the line signal and coverts the input signal into integrated flow rate data to execute meter inspection.
