SYSTEM FOR MONITORING PIPELINE STATE IN REMOTE PLACE TO PREVENT ACCIDENT SUCH AS PIPELINE DAMAGE AND GAS LEAKAGE

摘要

PURPOSE: A system for monitoring a pipeline state in a remote place is provided to monitor a state of a city gas pipeline connected to each customer home from a regulator controlling a pressure of city gas in the remote place, and to prevent a large accident such as pipeline damage and gas leakage. CONSTITUTION: A central controller(110) placed in a monitoring room(80) detects the gas pipeline state by using the data detected from a sensing terminal measurer(150), and outputs a command for emergency mobilization, valve cut-off, and regulator pressure control when an abnormal situation is generated. A signal generating/transferring device(130) transmits the detection data by receiving a control command from the central controller. A central connector(140) transmits the signal to the signal generating/transmitting device through the buried pipeline. The sensing terminal measurer transmits the measured data to the central connector through the buried pipeline. An adjuster(160) controls the gas pressure depending on the control signal from the central controller. A cut-off device(170) cuts off a valve(30) by the control signal from the central controller.
