摘　　要：介绍了动态分时方法来分配信道访问控制权 ,并在总线型网络上用令牌的方法实现了集散式计算机控制系统的多机通信。为了保证令牌交换的可靠性 ,对令牌进行的异或效验。由于集散控制系统底层的各个模块都是采用 80 3 2或 80 98,为了在大批量数据的通信时不影响控制模块的正常工作 ,网络的通信采用单片机串行口的模式 2和 9位异步通信。The method of dynamic sharing was introduced to allocate channel visiting control weight. And realized telecommunication between multi-computer control systems in Bus network of Distributed control system. Exclusive-OR to ream in order that secure reliability of ream exchange. As a result of substrate modules of multi-computer control systems using 8032 or 8098, in order to got have not affecting to modules woke in telecommunication at great deal of data, network telecommunication used model 2 of computer on-slice serial port and 9bit asynchronous communication.
