单片机煤气泄漏报警装置

陈光俊，物理与电子信息学院

摘要：现如今，出现了许多一氧化碳报警器，而这些产品大都是针对煤气的泄漏所做出的相应的声光报警，形式简单。但是随着社会的发展，一氧化碳报警器也在发展，也将由单一声光报警，发展为智能报警。由于煤气泄漏具有巨大的危害性，需要对煤气泄漏进行实时的精确监控。本文介绍了一种智能型煤气监控系统，该系统利用单片机控制技术，采用巡回检测的方法，实现对煤气泄漏的实时监测、实时跟踪显示现场煤气浓度并根据传感器老化曲线进行误差修正、具有声光报警功能等。

由于本设计以AT89C51单片机为核心，较为合理地分配了软硬件，充分利用了软件编程技巧及系统运行速度快等优点，并有力兼顾了系统的性能，使系统精确度、灵敏度和稳定性均达到设计要求。

Single-chip gas leak alarm device

ChenGuang-jun, College of Physics and Electronic Information

Abstract：In the current society, a lot of CO gas alarms have appeared, and these products are mostly to letting out sound-light corresponding alarms made of the leakage CO gas. That is a simple style. But with the development of society, CO gas alarm also developed from a single sound-light one to an intelligent one.Because of the gigantic harmfulness of gas leakage. It is important to measure the gas leakage accurately. The intelligent gas monitoring and controller system is designed with single-chip computer technology and cycle check method. It can monitor CO intense real-time. When CO concentration is higher than allowed value, it can not only provide with the function of setting up alarm limit, sound and light alarm, dynamic display of the connection error, checking and adjustment automatically.
