基于单片机的煤气智能报警系统的设计
[摘要] 随着经济和科学技术的快速发展,人们对生活质量的提高和生活环境的改善越来越重视。管道煤气与灌装煤气的使用为人们带来了方便,也改善了城市的环境,但同时也给人们带来了潜在的危险。由于使用的不当以及设备的老化等原因所引起的煤气泄漏极大地威胁着人们的生命财产安全,因此对于煤气浓度的检测与控制就变得至关重要,研究各种气体的检测方法与气体传感器也随之成为一个重要课题。
本论文是一篇基于单片机的煤气智能报警系统的设计。该系统可对煤气浓度进行实时监测,当被测气体中一氧化碳的浓度超过预定数值时,将产生报警并自动关闭煤气阀门。经过多次测试,该设计达到了精确度、灵敏度和稳定性高的要求,且成本低,操作方便,因此可广泛用于智能报警器与监控系统。

The Design of Intelligent Gas Monitoring and Alarming
System Based On Single Chip puter
[Abstract] With the rapid development of economy and the science technology, people e pay more and more attention to the quality of life and improving the environment. Pipeline gas and filling the use of gas for people brought convenient, also improve the environment of the city, but also has brought people of potential danger. Due to the improper use of equipment and aging causes of gas leakage greatly affecting people's life and property security, so for the measurement and control of gas concentration is crucial. And it is obviously very important to study on the inspection methods and sensors of all kinds of gases.
The paper is a design of intelligent gas monitoring and alarming system based on single chip puter. The system can real-time monitoring of gas concentration, and when the concentration of carbon monoxide in the air more than book value, will have a warning and automatically shut off the gas valves. Many tests have proved that this system satisfactorily meet the needs of high sensitivity, accuracy and stability in gas management. And it is low in cost and easy in operation, so a wide use can be expected in the gas industry market.
