小区煤气泄漏监控系统的设计与实现

Designing and Realizing of Gas Leakage Monitoring System

介绍了一种基于RS485和USB总线技术的小区煤气泄漏监控系统的组成与原理。该系统不仅能及时准确地检测出煤气的泄漏,发出声音报警;同时启动阀门关闭煤气管道;而且可以充分发挥RS485和USB两种总线的优点,能够进行长距离、高速度的多路信号采集与传输。该系统具有较高的工作可靠性,较强的测控功能,及易于扩展性。

This article introduces the composition and the principle of a residential area gas leakage monitor system based on RS485 and the USB main line technology. It presents that this system not only can promptly and accurately examine the gas divulging, sends audio warnings, and could simultaneously start the valve closure gas pipe, but also can fully take advantages of RS485 and USB main lines to collect and transmit multi-channel signals at a high speed over long distance. It also demonstrates the high operational reliability and effective monitoring function of this system.
