一种下位机共享总线的竞赛控制器的设计

采用总线方式设计的竞赛控制器,上位机与下位机之间的多采用独立连接,连线复杂,使用、存放都不方便。针对这个问题,提出下位机共享双绞线总线的设计。较详细的分析了电路的工作原理,给出了硬件电路构成,软件设计思路,程序流程图等。

The design of the competition Controller of Lower Computer Sharing bus

At present, the competition Controller based on bus commonly has the following problems: independent connectivity, compli-cated tie line and inconvenience in using and holding. In order to solve these problems effectively, the model based on lower com-puter sharing twisted-pair Cable is presented. At the same time, in the paper the working Principle of the circuits has been ana-lyzed; constructions of the hardware and the flow chart of the software design have been given. The experiment results show that the transmitting capacity and Stability of this competition Controller is better.
