摘　　要：目前分布式测控系统广泛应用于各行各业,多数分布式系统中控制终端地理上分散、所处环境恶劣、拆装困难,终端控制程序远程更新的问题亟待解决。提出了一种分布式测控系统中控制终端的程序下载方法,该方法使用系统中串口总线网络从主机传输程序代码到控制终端,解决了现场调试中需要拆下控制终端的程序存储器来重新烧制程序的问题。该方法不仅适合于现场调试,也给程序修改和升级带来方便。Now distributing center system is used widely,the controlling terminals are located dispersedly in the system where the environment is bad and it＇s difficult to fix and remove them.It＇s an important problem to solve terminal program update remotely.A method of program update remotely is put forward.In this method,host can transmit the program code to controlling terminals through serial port.So it＇s not needful to knocked-down the program memories of the controlling terminals to update program.This method is not only adapted to debug in the field and convenient for modify and update program.
