基于网络的调度模拟屏控制系统

The Control System of Dispatch Mimic Board Based on TCP/IP

针对模拟屏通讯普遍采用串并行传输方式易受到干扰、接线复杂不能实现显示单元自检、回码返回等缺点,提出一种基于TCP/IP(Transfer Control Protocol/Internet Protocol)的解决方案,从硬件组成、通讯规约、控制软件设计等几个方面对该系统作了阐述。

Quite few problems were apt to be brought in the control system of mimic board and parallel transmission in the past, for example, signal is easy to be disturbed, connection is very complex, unit can not be self-checking and return check code. The paper presents a solution based on TCP/IP transmission, discuss the hardware, communication protocol and control software.
