单台PC机与多台健康测试仪的串行通信控制

在实时体质测试系统中,数据需要从测试仪传送到主机上,为了提高控制的实时性及接收端对数据的反应速度,利用VB 6.O下的ActiveX控件和中体同方的健康测试仪RS-485的串行通信接口,实现了在Win-dows2000环境下,单台PC机与多台健康测试仪的串行通信,并能实时获取各测试仪测试项目的数据采集.将分立的各单项体质测试仪组合成一个体质健康测试系统,经测试后投入实际使用,整个通信系统运行稳定、操作灵活方便,通讯波特率达64 kbit/s.便于进一步进行数据分析、健康评价等研究.

Serial communication control between single PC and many sets of apparatuses of measuring physique healthy

At the real system of measuring physique health,data is required to transmitted from the measuring apparatuses to the host computer. In order to improve the real control and the response rate during the end receiving data, by combining activex controls of VB 6.0 with the RS-485 serial communication port of CSTF apparatuses of measuring physique health, the goal that single PC serially communicates many sets of apparatuses of measuring physique health under the environment of Windows2000 has attained. Test data can be obtained from every measuring apparatus in real time. The high quality system for measuring physique health is designed by connecting individual apparatuses of measuring physique health. After careful test, this system has been put into practice, which runs steadly and operates flexibly. The rate of Potter of communication reaches 64 kbit/s. It is beneficial to carry on the future research such as data analysis, health estimate and so on.
