摘　　要：针对目前宿舍防火防盗报警系统现状以及所存在的主要问题,提出了一种基于RS 485总线的宿舍智能防火防盗报警系统。系统采用烟雾传感器,红外传感器和热释电传感器作为检测元件,以Philips公司生产的32位ARM7TDMI-SCPU的微控制器LPC2103作为主机部分的处理器,STC89C52作为从机部分的处理器,利用MAX485收发器芯片完成了智能报警系统的设计,实现了低误报率,增强了系统的可靠性。According to present situation of fireproof and theftproof alarm system for dormitorys and in order to solve the remaining main questions, a intelligent fireproof and theftproof alarm system based on RS485 bus is proposed for dormitorys. The photoelectric smoke sensor, infrared sensor and pyroelectric sensor are adopted as detection elements. The 32-bit ARMTTDMI-S CPU micro-controller LPC2103 produced by Philips Company is taken as a processor of the host machine, and STC89C52 as the processor of the slave machines. MAX485 transceiver chip is employed to complete intelligent alarm function. It reduced the false-alarm rate and enhanced the reliability of the whole system.
