基于CPLD的多通道智能爆速仪的设计

Multi-channel Intelligence Explosive Rate Instrument of Based on CPLD

设计以单片机为控制核心,设计了基于CPLD的8通道智能爆速测量仪。整个测量仪的系统主要分为三个模块:即信号产生、调理的前端模块;利用CPLD实现的16位计数器、自检电路、数据选通和缓存三个部分的测时模块;以单片机为核心的数据计算、输入输出、无线通信以及LCD显示的控制模块。设计中CPLD器件的利用简化了仪器电路板设计,提高系统测试精度,另外无线通信模块的利用可以提高爆速测量的灵活性和安全性。

This design is MCU control,based on the core design of 8 channel intelligence CPLD critical speed measuring instrument.The whole of the apparatus used to measure system mainly divided into three modules：namely signal the front end of the module,tones？鸦Use CPLD realize of 16 counter,self-check circuit,choose the data and the cache three parts of the test module？鸦when Is mainly composed of the data calculation,input/output,wireless communication and LCD display control module.
