为提高多点温度检测系统的实时性和可靠性，提出了一种基于AT89S52单片机的无线多点温度检测语音无线报警系统的软硬件实现方案。采用 AT89S52单片机对现场8点的温度实时进行采集检测，当温度超过限定值时，用PCD3311双音频发生器自动拨打值守人电话，通过ISD4004语音芯片将报警信号通过无线传送到值守人员，实现远程监测和报警。应用该系统可以减少值班人员工作强度，提高系统的可靠性。

In order to improve the real?time performance and reliability of multipoint temperature detecting system, the paper proposes a wireless multipoint temperature detection wireless alarm system based on AT89S52 single chip microcomputer, using AT89S52 single chip microcomputer to detect the real?time temperature of 8 locations. When the temperature exceeds the limit, the PCD3311 double audio generator will automatically call the on?duty staff,and the ISD4004 voice chip will give alarm signal to the on?duty staff through wireless transmission,realizingremote monitoring and alarming.The application of the system can reduce the workload of the on?duty staff and improve the reliability of the system.
