家用煤气泄漏报警控制器设计 摘要 当今社会上，出现了许多煤气报警器，而这些产品大都是针对煤气的泄漏所做出的相应的报警，即为家庭式。但是随着社会的发展，煤气报警器也在发展，也将由单一的家庭式，发展为小区监控。本文就是学习如何对一个小区的煤气泄漏进行监控，并设计了一个监控四个单元的煤气报警系统。 煤气报警系统采用了8位8051单片机为系统的CPU，四个单元的煤气浓度对应模拟量利用A/D转换为数字量，并加入了键盘输入。整个系统的硬件电路设计合理，性能安全可靠。 本系统的软件编写采用的是汇编语言，整个程序的思路清晰，考虑全面。可以在执行的开始和过程中，修改报警临界值，增大了使用的地域和领域；在报警时可以指出哪个单元煤气泄漏并且发出音乐，增强了人性化。 关键词　电位器采样；报警临界值；煤气浓度 Abstract In the current society, a lot of coal gas alarms have appeared, and these products are mostly to letting out corresponding alarms made of coal gas , it is family. But with the development of society, coal gas alarm develop too, family by a single one too, develop into the district to control. This text studies how to let out and control the coal gas of a district, and has designed a coal gas warning system of controlling four units. Coal gas warning system adopt 8 8051 one-chip computer CPU of system, four coal gas density corresponding analog quantity of unit utilize A/D person who changes figure into, and has joined key in. The hardware circuit of the whole system is reasonable in design, performance is safe and reliable. What the software of this system is written and adopted is an assembler language , the train of thought of the whole procedure is clear, it is overall to consider. Can revise the warning critical value , has increased the region and field to use in beginning and course of carrying out ; Can point out which unit coal gas let out and send out the music while reporting to the police, have strengthened humanization.
