摘　　要：介绍了飞机救生衣防盗报警检测装置的设计。本设计采用EPLD可编程逻辑器件实现了40kHz载波频率的脉冲编码信号的生成与解码,防盗报警检测装置输出的无线电信号可使2m距离内的救生衣防盗报警模块发出声音报警,EPLD对防盗报警模块发射出的被盗信号进行解码分析,确认后通过声音和闪光报警指示有被盗事件发生。This paper mainly introduces the design of an aircraft life vest anti-theft alarm detection device. With EPLD, a programmable logic device, the design achieves the generating and decoding of pulse code signal at the carrier wave frequency of 40 kHz. Radio signals from the device can make the life vest anti-theft alarm module sound alarm within 2 meters. Then EPLD decodes and analyses the stolen signal, and once confirmed, the device will give an audible warning and a flashing alarm.
