摘要
数据采集控制系统的性能对汽车驾驶模拟系统的交互性和真实感有重要影响。根据模拟器数据采集与控制的多输入输出接口和快速响应要求,设计了一套实时数据采集控制系统。该系统基于STM32单片机实现了对4路格雷码编码器、1路SSI编码器、24路数字量输入和8路数字量输出的数据采集处理与控制,通过USB以及RS232与上位机通讯,系统软件采用C语言模块化编程技术。实验结果表明所设计的数据采集控制系统实时性好,可靠性高,能满足实际需求。
The performance of data acquisition and control system has a significant effect on the vehicle driving simulation system, especially on interaction and reality. According to the requirement of multiple input-output interface and fast response on the data acquisition and control simulator, a set of real-time data acquisition control system based on STM32 microcontroller, using C language modular programming technology, is designed to realize the data collection processing and control with four-road gray code encoder, a SSI encoder, 24 digital signal input and 8 digital signal output, and communicate with PC by USB/RS232. The experimental results show that the designed control system of data acquisition reveals with good real-time performance and high reliability, and meets the actual requrements.
