用VC++6.0和80C196KC单片机实现拖拉机仿真机组综合控制

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80C196KC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。

Using VC++6.0 and 80C196KC Single-chip Microcomputer to Realize the Integrated Control of the Simulated Tractor-implement Combination

The function and work principle of simulation control system were introduced. The simulated set of tractor implement combination was composed of center monitor, engine & transmission control sub system, suspension & load control sub system and electric eddy current dynamometer control sub system, which are connected in a distributed integration control system with RS 232C and Data Acquisition & Control Card. It is a control system with response lag. The information exchange among the control sub systems was completed by serial communication. Using MSComm control in the Visual C++6 0 environment by making a reasonable communication protocol between master PC and slave Microprocessors, program to realize distribute integrated control of the simulated tractor implement combination with serial communication. The experiment result showed that the control system have a good control characteristics and meet the experimental needs. This method has a utility significance for study of tractor implement control system.
