CPLD在飞机电气参数测试系统中的应用

Application of CPLD in airplane electrical parameter testing system

针对飞机电气参数测试系统具有采样速率高,精度高,通道多且可变的特点,提出了用CPLD实现通道高速轮巡的新方法,使用Verilog HDL语言在MAX+PlusⅡ环境下对方案的功能进行了仿真,结果证明了方案的有效性,并且这一技术已成功应用于新型飞机电气参数测试系统。

According to the traits of high speed, high precision, multi-channel and channel changeability of the airplane electrical parameter testing systems, a new method to implement high-speed channel cycle by CPLD （complex programmable logic device） is presented. The Verilog HDL was adopted to do function simulation of the method in MAX＋PLUS II. The simulation result indicates the validity of this method. This technology has been triumphantly used in the electrical parameter testing system of a new airplane.
