[摘要] 汽车成为很多不可缺少的交通工具，现在汽车被盗的现象时有发生，盗贼的手段也层出不穷，为对付不断升级的盗车手段，人们已经进行一些防盗装置的研制为了对盗窃行为进行有效的监测和报警，设计了一种基于单片机的无线防盗系统，系统主要由硬件与软件两部分组成，硬件包括人体热释电红外传感电路、无线收发电路、控制处理电路和温度感应等。当红外感应器感应到人时会发出高电平信号且当温度超过设定温度时候就会发出报警信号，使得蜂鸣器报警，在通过无线传输使得远程也接收到报警信号，使得车主能够与时作出应急措施。

Abstract：Many cars become an indispensable means of transport, car theft is now the phenomenon have occurred, the means thieves are endless, to combat the escalating theft means, people have developed some security devices in order to carry out effective monitoring of theft and alarm, the design of a microcontroller-based wireless security systems, hardware and software system is mainly composed of two parts, hardware, including human pyroelectric infrared sensing circuit, wireless transceiver circuit, control circuit and temperature sensors and other processing. When the infrared sensor senses that the person will be issued when a high level signal when the temperature exceeds the set temperature and time will be an alarm signal, making the buzzer alarm, remotely via wireless transmission makes it receives the alarm signal, so that owners can timely make emergency measures.
