介绍了如何选择不同的通信方案 ,如何选择合适的监控子系统 ,包括其构成和实现方法。主要思想是以Ethernet、RS4 85网络和电话网为基础 ,根据不同距离和环境条件选用不同的网络技术 ,根据具体控制条件及技术要求采用不同的控制系统 ,实现分散系统的集中监控 ,以及该方案在油气集输方面的系统应用。本系统适用于对实时性要求不同和地域分散的多个小系统进行监控
Introduced how to choose different communication schemes, how to choose the appropriate monitoring subsystem, including its composition and implementation method. The main idea is based on Ethernet, RS4 85 network and telephone network, based on different distances and environmental conditions using different network technologies, according to the specific control conditions and technical requirements using different control systems to achieve decentralized centralized monitoring system, and the program System Application in Oil and Gas Gathering and Transportation. The system is suitable for real-time requirements of different and scattered geographical system to monitor multiple small
