VALVE CHAMBER REMOTE MONITORING SYSTEM BASED ON NARROWBAND INTERNET OF THINGS COMMUNICATION NETWORK

摘要

The present invention relates to a valve chamber remote monitoring system which monitors a state of a valve chamber in which a valve of a pipe is sealed, wherein the valve chamber is remotely controlled by a central monitoring unit. The valve chamber comprises: a sensor unit including a gas leakage sensor, a water level sensor, and a protection potential measuring sensor; a wireless signal transceiving unit transmitting values measured in the sensor unit to the central monitoring unit with a wireless signal, and receiving wireless signals related to a control of the valve chamber from the central monitoring unit; and a control unit electrically connected to the wireless signal transceiving unit and configured to control an operation of the sensor unit in accordance with a signal received from the central monitoring unit. The wireless signal transceiving unit can transceive the wireless signal through a narrowband IoT communication network.;COPYRIGHT KIPO 2019
