摘 要摘 要近些年，电子科学技术和计算机软硬件技术的飞速进步，在许多领域上已大面积应用火灾报警系统和灭火系统。高性能的单片机已成为控制核心的主流，由于其工况稳定性高，精度高，通用性能良好且功耗低，这些因素保证了其报警的可靠性和准确性。本设计的电路由交一直流转换电路，稳压电路，气敏传感电路，温度监测电路，数模转换电路，单片机控制电路，数码管显示电路和无线传输电路共同构成。通过这些电路可实现数据处理，数据显示系统，时间显示区块，状态显示区块，故障检测，报警气体报警信号采集，实现无线传输、多点位实时监控和联动消防等功能。软件部分采用 ptotel 绘制电路图。本设计可完成烟气温度数据采集报警到消防联动的全部过程。关键字：单片机 火灾报警 消防联动 数据采集IAbstractAbstractIn recent years, with the rapid progress of Electronic Science and computer software and hardware technology, fire alarm system and fire extinguishing system have been widely used in many fields. High performance single chip microcomputer has become the mainstream of the control core. Because of its high stability, high precision, good general performance and low power consumption, these factors ensure the reliability and accuracy of its alarm. The circuit is composed of AC-DC conversion circuit, voltage stabilizing circuit, gas sensing circuit, temperature monitoring circuit, digital to analog conversion circuit, single chip microcomputer control circuit, nixie tube display circuit and wireless transmission circuit. Through these circuits, data processing, data display system, time display block, status display block, fault detection, alarm gas alarm signal collection, wireless transmission, multi-point real-time monitoring and linkage fire control can be realized. The software part uses ptotel to draw the circuit diagram. The design can complete the whole process from flue gas temperature data collection and alarm to fire linkage.Keywords: Singl...
