摘　　要：系统集成了高灵敏度的DS18B20温度传感器、热释电人体红外传感器、MQ-6可燃气体传感器,起到防火、防盗、防液化气或天然气泄漏的作用,同时采用PT2262/2272编解码技术,通过电磁波实现无线通信功能,传输距离远,穿透能力强。选用AT89C2051单片机作为处理系统,实现数据的采集、发送、接收,以及相应的报警功能。The system integrates high sensitive DS18B20 temperature sensor, infrared human body detect sensor and MQ -6 combustible gas sensor. It is useful in fireproofing, guarding against theft and preventing from the leakage of coal gas or liquefied natural gas. Also the system adopts PT2262/2272 technology of coding and decoding, and makes use of electromagnetic wave to communicate wirelessly. The communication works between long distance and penetrates remoras. The processor is AT89C2051 single chip. It carries out data collection, communication and can give a corresponding alarm.
