摘要
提出了一种基于复杂可编程逻辑器件(Complex programmable logic device,CPLD)与PIC单片机的多路快速高精度数据采集系统的新方法。仿真和实际测试结果表明,所采集数据具备良好的实时性,可采集通道数目多,同时系统具备较强的抗外界干扰能力,结构简单,可靠性好。该系统具有较强的可移植性,能够广泛应用于多路高精度低频数据采集的场合。
A new multi-channel and rapid high-precision data acquisition system is proposed based on complex programmable logic device(CPLD) and PIC microcontroller.The simulation and practical test results indicate that the data collection is real-time and can collect more than one channel simultaneously.Moreover,the system has strong anti-interference capability,simple structure,good reliability,and strong portability.Thus,it can be widely used in multi-channel,high-precision,and low-frequency data acquisition applications.
