计算机与多台单片机的串行通信方案实现

A Method of Serial Communication between PC and Multiple SCM

为了提高靶场测试系统的运行效率,提出了一种计算机与多台单片机通过串行口进行数据传输的方法。引入RS485总线,使用一台计算机通过不同的地址命令控制分布在不同位置的测试系统中的单片机,令单片机将采集到的数据发送给计算机,形成分布式测试系统。本文研究的多机串行通信方案具有一定的先进性,其性能经过试验现场验证工作稳定、可靠。

In order to improve the efficiency of shooting range testing system,a method of data transmission using serial communication between PC and multi-SCM is introduced.The testing system lying on different place is under control by PC using address data,and the data acquired by SCM transmit to the PC.The method using serial communication between PC and multi-SCM is stability and safety,and can achieve the require of shooting range.
