本设计是采用单片机作为从机（也称下位机），而PC机作为中央控制机的主从式系统。主机同时根据从从机接收的过程参数进行判断处理并给从机发送各种控制命令。利用单片机的串行口与PC机的串行口进行串行通信，PC机可对远程前端单片机进行控制，将单片机采集的数据传送到PC中去，由PC机对数据进行处理和显示，同时把反馈信号发到单片机，实现闭环控制和管理。本设计在VC++6.0的环境下，编写使用C++语言，SQL数据库的串口通信程序，控制由单片机控制的智能小车。

This design is a master-slave system which uses SCM as the slave (also known as PLC), and PC as the central control unit. The host carries out judging processing of the process parameters received from the slave and send various control commands to the slave. The serial port of SCM and the serial port of the PC are used for serial communications. The PC can remotely control front-end SCM, and send the collected data to a PC for data processing and display, while sending the feedback signal to the SCM, realizing closed-loop control and management. This design is a smart vehicle under VC++6.0 environment, and uses C++ language to write, SQL database serial communication programming language.
