Research on well site H2S detection system

A kind of well site hydrogen sulfide detection system is designed because toxic gas-H2S may present in the developing process of high sulphur gas field in the east of Sichuan Basin. The design elaborates the developing process of software and hardware of H2S detection system. In hardware part, 51 MCU is the core chip, hardware circuit is composed of signal conditioning circuit, data acquisition circuit and communication circuit; in software part, MCU software and computer software can be developed by C language and Lab VIEW respectively. Tests on the H2S detection system show that system measurement error is less than 0.2% so it can satisfy the need of high-accuracy measurement of H2S in well site. © 2013 Asian Network for Scientific Information.
