摘要

摘要: 沼气工程是一项以开发利用养殖粪污为对象,实现农业生态良性循环的农村能源工程。智能化监控技术可以通过采集和监控沼气工程运行过程中各项指标来提高工程运行的稳定性。对沼气工程的主要监测技术、自动化控制技术及其装备研发应用进行了分析,结果表明:沼气工程监控制技术目前存在监测指标不完善、传感器使用寿命低、自动化程度低等问题;为进一步提升沼气工程智能化水平,还应对发酵过程机理进行深入研究,研发、改进适用于实际沼气工程高精度、高寿命的监测传感器,推动物联网等技术在实际工程的应用,提高智能化运行效率。并基于对沼气工程监控技术的梳理,结合当下相对成熟的技术,以PLC控制系统为例构建了一套可靠、可行、低成本易于推广的沼气工程智能监控系统,为沼气工程智能化监控技术提供了参考。

Abstract: Biogas engineering is a rural energy project aiming at developing and utilizing livestock manure to achieve a virtuous cycle of agricultural ecology. Intelligent monitoring technology can improve the stability of engineering operations by collecting and monitoring various indicators during the operation process of biogas engineering. This article analyzes the main monitoring technologies, automation control technologies, and equipment research and development applications of biogas engineering. The results indicate that the monitoring and control technology of biogas engineering currently has problems such as incomplete monitoring indicators system, low sensor service life, and low automation level; to further improve the intelligence level of biogas engineering, in-depth research should be conducted on the fermentation process mechanism, and the development of high-precision and long-life monitoring sensors suitable for practical biogas engineering should be improved. The application of emerging network technologies such as animal networking in practical engineering should be promoted to improve the efficiency of intelligent operation. Based on the review of biogas engineering monitoring technology, combined with the current relatively mature technology, this paper took the PLC control system as an example to build a set of reliable, feasible, low-cost, and easy to promote biogas engineering intelligent monitoring systems, to build a set of intelligent biogas engineering monitoring systems to achieve the monitoring of various indicators of the biogas engineering system, automatic feeding, heating, stirring, etc. The operation stability of the whole system is improved, which provides a reference for the intelligent monitoring technology of biogas engineering.
