介绍了拖拉机仿真机组控制系统的组成、作用和工作原理。它是一个由中央监控系统和多个子系统组成的、响应有滞后的分布式控制系统 ,对这样的控制系统 ,串行通信控制是一种有效的控制方法。在控制系统中 ,上下位机的信息交换通过串行口完成 ,可靠地传输控制信号和准确地执行控制命令是实现控制目的的关键。在 VC+ + 6 .0环境下利用 MSComm控件 ,制定了具体的通信协议 ,编程实现了和 80 C196 KC单片机串行通信的分布式综合控制。试验结果表明 ,控制效果很好 ,具有一定的实用意义
The composition, function and working principle of tractor simulation unit control system are introduced. It is a distributed control system consisting of a central monitoring system and multiple subsystems with a lagging response. For such a control system, serial communication control is an effective control method. In the control system, the exchange of information between the upper and lower computer through the serial port to complete, the reliable transmission of control signals and accurate control commands are the key to achieve control purposes. In VC + +6 .0 environment using MSComm control, developed a specific communication protocol, programmed and 80 C196 KC SCM serial communication distributed integrated control. The test results show that the control effect is very good and has certain practical significance
