Research on Well Site H₂S Detection System

摘要

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 LabVIEW 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.
