Abstract

The invention discloses a gas leakage detector. According to the gas leakage detector, based on a non-dispersive infrared technology theory, a light-emitting diode (LED) and a photodiode are arrangedthrough single-channel design, the LED emits a radiation wavelength corresponding to a gas absorption band, the photodiode detects an absorbed spectrum and converts the absorbed spectrum into an electrical signal, and a controller is applied to achieve control over a light-emitting circuit and feedback information processing of an amplification circuit. Simple and compact sensor design is applied,and in combination with autonomous low-consumption power supply, acceptable qualitative and quantitative analysis results are given.

Description

【Technical field】 [0001] The invention belongs to the field of energy production, and in particular designs a gas leakage detector. 【Background technique】 [0002] At present, the monitoring of wellhead data in various oil production plants in the oil field has basically realized the monitoring of pressure, power chart, and electric parameters. However, whether the oil production of the oil production tree is normal or not depends on manual inspection. Experience and professionalism. At present, some blocks are monitored by cameras, and the personnel in the monitoring room check remotely. If oil leakage occurs, the pumping units will be stopped immediately. However, the large number of oil wells and the high work intensity cannot realize intelligent monitoring. [0003] In order to solve the problem of manually inspecting Christmas trees, the invention provides a gas leakage detector. 【Content of invention】 [0004] The purpose of the invention is to solve the problem of ...
