摘要
介绍了一种家用燃气报警装置的组成、原理及软件流程,它采用廉价的AT89C2051作为主控制器,电容双积分电路构成A/D转换。通过软件设计,使其具有一键校零、燃气浓度存储与查询等功能。实际测试表明,该装置测量误差小,可靠性高,操作简单,适合家庭推广使用。
This paper introduces the composition,circuit principle and software process of a kind of domestic gas alarm device, which uses AT89C2051 as the main controller.A Capacitor double integral circuit Constitute the A/D conversion.Through the software design,it has clearing with one key,Gas concentration storage and query functions.The actual test results show the equipment has small measuring error,high reliability,simple operation.So it suits for family extended use.
