郑州大学 升达经贸管理学院毕业论文 多路无线防盗报警系统的设计 学 号： 206607058306 学生姓名： 嘻嘻嘻 专 业： 电子信息工程 指导老师： 刘大纲 提交时间： 2011-4-18 摘要 如今市场上成熟的无线防盗报警产品有被动式的、主动式的和多技术复合式的。但前两者都有致命的缺点就是误报率很高，而多技术复合式的防盗报警器误报率很低，也是未来发展的主要方向。个人认为设计无线防盗报警器的意义在于设计的过程，在设计的过程中我们才会把这几年在学校里学到的融合，同时也让自己明白我们的学习道路还很遥远。 本设计的目的在于设计出一个安装和配置容易成本低使用非常方便的多路无线防盗报警器热释电红外传感器系统主机接收电路的无线接收与解调部分采用的是现成的高频接收模块，可以简化设计工作，而且可靠性较好，使用起来也较方便，接收模块采用的是超再生接收。原理是利用传感器探测信号再通过无线发射模块发射出无线信号，无线接收模块接收到信号后经过数据处理后，再通过报警电路后发出报警声，另一方面输出具体的地址信息，确定是哪一路发送了报警信号。主机电路由高频接收模块接收发来的报警信号，通过解码器解码后得到报警传感器的地址和数据类型。传感器ABSTRACT Now the market mature wireless security alarm products are passive and active and more complex technology. But former both fatal flaw is the rate of false positives high, and more complex technology alarm system misstatement rate very low, also be the main direction of future development. People think the significance of wireless alarm system design is the process of design in design process we will take this years learned in school, also let oneself fusion understand that our learning road is still very far away. This design aims to design a has the misstatement rate lower, installation and configuration easy, low cost, use very convenient, has certain practical value of multi-channel wireless alarm system. This design is proposed by way of wireless alarm system design, the multiple wireless alarm system by pyroelectric infrared sensors, wireless accept, data decoding, central processing unit and alarm circuit etc. This paper analyzes the multi-channel wireless alarm system, and the basic principle of hardware circuit and software detailed design. First is the overall design scheme for the system function module partition. The first part is infrared detection emitter (can be multiple detection transmitters separately installs the place in need protection); The second part is main engine (including receiver, processors, alarm and etc); The third part i
