摘　　要：介绍了三维力测力平台的系统结构,提出了一种基于多线程的数据采集系统设计方案,详细阐述了数据采集系统的设计思路,实现方法,以及系统的程序流程。在系统中通过采用两个独立的线程,分别实现数据采集与数据融合显示,线程之间通过数据共享相互关联,通过互斥、基于优先级的调度等方法进行控制。经实验测试表明,系统结果正确,工作稳定,实时性与可靠均较好,较成功地满足了三维力测力平台数据采集的需要,具有较好的实用性。This paper presents the system structure of the three axes force platform, proposes a multi-thread method of data acquisition system, also elaborates the design ideas, the implementations and the program flow of the data acquisition system. The system realizes the display of the data acquisition and the data fusion by using two independent threads. The two threads are linked by data sharing, controlled some methods as mutual exclusion and the dispatch based on priority. The experimental test shows that, the system＇s result is correct, the system runs steadily and has a good performance of real time and reliability, it＇s proved that the method could meet the requirements of the three axes platform＇s data acquisition successfully, and has good practicability.
