Remote wireless controlled coal gas alarming system

Abstract

The invention provides a remote wireless controlled coal gas alarming system. The remote wireless controlled coal gas alarming system comprises a gas collection module, wherein the gas collection module is connected with an analog-to-digital conversion device; the analog-to-digital conversion device is connected with a wireless transmitting end by an encoding circuit; a wireless receiving end is connected with a controller by a decoding circuit; the controller is connected with an exhaust fan, a buzzer alarm and a solenoid valve; the solenoid valve is connected with a coal gas pipeline; the gas collection module is used for collecting a signal and carrying out analog-to-digital conversion; a digital signal is transmitted by the wireless transmitting end through the encoding circuit; after the wireless receiving end receives the signal, the signal is decoded by the decoding circuit; finally, the controller is used for processing data and controlling the exhaust fan to start to rotate; meanwhile, the buzzer alarm raises the alarm to control the solenoid valve to block the coal gas pipeline; the coal gas can be monitored and the alarm is raised in time when leakage occurs; the remote wireless controlled coal gas alarming system has the characteristics of accuracy and rapidness in monitoring and high sensitivity.

Description

Technical field [0001] The invention belongs to the field of control systems, and particularly relates to a gas alarm system controlled by remote wireless. Background technique [0002] Gas or natural gas is a common fuel in most households, but there are more and more fires and personal injuries caused by gas leaks. Carbon monoxide is colorless and odorless, leaks are difficult to detect, and prevention of gas poisoning has become an urgent need. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a gas alarm system controlled remotely and wirelessly, which can monitor the gas and give an alarm in time when leakage occurs, and has the characteristics of accurate, fast and high sensitivity monitoring. [0004] In order to achieve the above objective, the technical solution adopted by the present invention is: [0005] A gas alarm system controlled remotely and wirelessly. It inclu...
