汽车拉杆总成试验台计算机测控系统研究

Research on Computer Measurement and Control System for the Test-bed of Automobile Tension Bar Assembly

以汽车转向拉杆球头销疲劳试验台为应用背景,阐述了如何采用VB6.0编程语言实现西门子S7-200系列PLC与上位计算机的串行通信,完成了PLC与计算机之间的数据交换,为最终实现计算机对PLC所连接的试验台工作状态的实时监控提供了通信支持。

Taking the text - bed of ball stud of automobile tension bar assembly as the application background, the question on how to use the VB6.0 programming language to realize the serial communication between Siemens S7 - 200 series PLC and the superior computer was elaborated. The data exchange between PLC and computer was completed, which provides the correspondence support for implementing the real - time monitoring of the active status of the test platform connecting PLC.
