摘要:

针对石油天然气井场安全生产需求,本文详细阐述了一款井场硫化氢监测系统的设计方案及软、硬件设计过程。监测系统利用成熟的单片机技术及虚拟仪器技术,以混合信号处理器MSP430F149作为现场控制器件,通过扩展外围信号调理电路、Flash数据存储器、RS485接口芯片以及相应的硫化氢监测探头,并将获得的数据传送至上位机进行处理,实现了在井场环境下多路硫化氢浓度实时监测及报警功能,对提高石油天然气生产现场安全保障具有实际意义。

Abstract:

To meet the requirement of safety production for petroleum and natural gas well site, a detailed description is made about the design scheme and the software & hardware design process of a H2S monitoring system in this paper. Mature microcontroller technology and virtual instrument technology was used in the monitoring system. The mixed signal processor MSP430F149 was used as a field control device. Through the expanded peripheral signal regu- late circuit, flash data storage, RS485 interface chip and the corresponding H2S monitoring probe, then transmitting the received data to the host computer, multiple H2S concentration real-time monitoring and alarm function were achieved in well site. The research is of practical significance in pro moting safety guarantee of petroleum and natural gas pro duction fields.
