摘　　要：在石油钻井测控系统的设计中 ,考虑到构成测控系统的各独立单元之间数据交换较为频繁 ,测控系统所处的工作环境较为恶劣 ,对测控系统分布式通信网络的通信速度、通信距离、抗干扰性等都有较高要求的实际需求 ,文中介绍了利用控制器局域网 (CAN)组建的分布式通信网络模块的方案。实践证明 ,以CAN总线作为构架来组建测控系统内部的分布式通信网络在通信速度、通信距离、通信网络的抗干扰性以及通信网络设计的灵活性上都完全满足测控系统的实际需求。In the design of the monitor and control system, the data of the individual units are exchanged frequently, at the same time, the working conditions of the system is very hard, which has strictly need for the communicative speed, communicative distance, as well as the anti disturbance. According to the actual need, the paper introduces the application of controller area network BUS for the system of the monitor and control. The actual operation has proved that the CAN BUS is fitful for monitor and control system in the communicative speed, communicative distance, the anti disturbance ability as well as the flexibility of the communicative network.
