本文采用科研领域广泛应用的、功能强大的MATLAB软件及其仿真工具箱Simulink、Real-time Workshop、xPCTarget研究开发了针丈接轮胎压力监测系统(TPMS)的数据采集与处理系统。 首先利用Simulink工具箱建立TPMS系统所需参数的处理方法仿真模型 然后构建了基于MATLAB/xPCTarget的硬件平台,并结合所建立的仿真模型完成了整个数据采集与处理系统的开发 最后,通过实车实验,实时地采集数据,对系统的采集和处理数据功能进行验证。(In this paper, widely used in the field of scientific research, powerful and simulation software MATLAB toolbox Simulink, Real-time Workshop, xPCTarget research and development of a needle then Zhangting Tire Pressure Monitoring System (TPMS) for data acquisition and processing system. First of all, the use of Simulink toolbox parameters required for the establishment of TPMS system simulation model approach then constructed based on MATLAB/xPCTarget hardware platform, combined with simulation models created by the completion of the entire data acquisition and processing system Finally, it is vehicle experiments, real-time data collection, the system of collection and processing of data validation functions.)
