Abstract

The invention discloses a gas leakage detection system. The gas leakage detection system comprises an ultrasonic flowmeter, an electromagnetic valve and an alarm subsystem, wherein the ultrasonic flowmeter and the electromagnetic valve are arranged in a gas pipeline; the ultrasonic flowmeter is used for collecting flow velocity data in the gas pipeline in real time, judging whether gas leakage happens to the gas pipeline or not and judging the gas leakage level when the gas leakage happens to the gas pipeline according to the flow velocity data and preset gas leakage conditions, and sending analarm command to the alarm subsystem and/or sending a valve closing command to the electromagnetic valve according to the gas leakage level when the gas leakage is determined to happen to the gas pipeline; the electromagnetic valve is used for closing the valve when the valve closing command is received; and the alarm subsystem is used for giving an alarm prompt when the alarm command prompt information is received. By implementing the embodiment of the invention, the accuracy of gas leakage detection can be improved.

Description

technical field [0001] The invention relates to the technical field of gas leakage detection, in particular to a gas leakage detection system. Background technique [0002] The existing gas leakage detection device is mainly composed of a gas alarm controller and a gas detector. The gas detector monitors the gas concentration in the surrounding environment. When the gas concentration reaches the alarm value set by the alarm controller, the alarm controller will send out Alarm signals and instructions, linkage solenoid valves or fans and other equipment to drive exhaust, power off and close valves and other disposal operations. [0003] However, monitoring the gas concentration in the surrounding environment through the gas detector cannot effectively monitor the gas concentration in the area outside the coverage of the gas detector, and the gas concentration in the surrounding environment is monitored by the gas detector. For the leakage of outdoor gas facilities, such as W...
