详细介绍了对采用现场总线的分布式测控网络中数据通讯方式改进的方法及其实施设计的措施,经改进后的通信控制方法能有效地解决总线争用、接收/发送数据信号时出现的少收和误收、数据传输误码等问题,大大提高了网络通信控制的有效性和实时性,并可提高设备的利用率。对实际应用系统的组成、功能、硬件/软件设计也作了一定的介绍。该装置投入运行以来,性能一直稳定,运行良好。
The method of improving the data communication method in distributed measurement and control network using field bus and its design measures are introduced in detail. The improved communication control method can effectively solve the problem of bus contention, and there are few problems when receiving / sending data signals Receiving and receiving errors, data transmission errors and other issues, greatly improving the effectiveness of network communications control and real-time, and can improve the utilization of equipment. The actual application of the system’s composition, function, hardware / software design also made a certain introduction. Since the unit was put into operation, the performance has been stable and working well.
