| Abstract: | This paper introduces the design of serial communications subsystem in a measure-control system which is operated in surrounding with strong electro magnetic interference(EMI). The subsystem consists of two level networks, both of the two levels are composed of RS-485 and optical fibers. And then the system communicates with PC through RS-232 interface. The circuits of the interfaces and flow-chat of the program are presented in the article. |
