摘 要 本文主要探讨了与人们日常生活联系密切的 智能 小区安防系统的设计问题，设计具有防盗，防火和防煤气泄露功能的智能小区安防报警系统。 系统的结构由三部分组成：报警传感器、单片机控制器、监控中心组成。 本系统采用了体积小巧，功能强大，价格便宜的单片微型计算机 AT89C51 作为小区住户家庭的第一监视端，与单片机相连接的各种用于家庭安保的传感器 用于家庭报警 ，收集各种报警信号，并送单片机进行初步处理，单片机实时与远方监控中心通信，通过 CAN 总线将传感器感受的信号传给主机，这样，监控中心就可以清楚的知道小区住户家里的异 常情况，以便及时的进行处理。该系统由于使用方便，价格合理，在实际的工程中，有广泛的应用，因而，具有良好的应用前景和推广价值。 该智能小区安防系统运用了 AT89C51 单片机、 四种报警传感器、模数转换ADC0809、 CAN 总线控制器 SJA1000 和 CAN 总线收发器 PCA82C250。本系统充分的 将主从式微机通信运用于今天的生活 ，体现了自动化的发展前景一片光明。 关键词： 小区安防； AT89C51；传感器；信号处理；报警器； CAN 总线 ntsAbstract This paper mostly describes how to design the guard system of uptown.The guard system provides many functions, such as guard against fire、 gas leaking out and so on, realizing the automatization of the public security of updown. This security alarm system structure is composed by three parts:the scenec controls measure,the family control measure, and monitoring center. Alarm system of updown is made up of clients and warning center. Use the chip of CAN to form the alarm network of uptown, and the software to carry out communication between clients and warning center. In the PC on board management report to the police signal analysis, showed warn information, convenient for and small area security personnel in time help handle excrescent affairs, and convenient to residents uptown. This system uses the CAN network to deliver the message, and improve the reliability, with more convenient operation, and used extensively in actual engineering, So it has a good applied foreground and extend value in engineering. This system introduces the main characteristic and principle of Singlechip AT89C51、several sensors、 SJA1000、 PCA82C250， using ADC0809 to collect datas, and then the expatiation on communication between principal and subordinate, and applicate this method to the control of MCS-51 series single-chip microcompu
