【Abstract】 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.更多还原
