摘　　要：针对水厂仪表可集成度低和网络兼容性差的缺点,设计了一种多网络融合的水厂自动化控制系统。系统节点选用Microchip公司基于M4K内核的处理器PIC32MX795F512L,使用该芯片内置的多种网络接口与仪表/设备互连,并给出了硬件方案、工业以太/CAN网络冗余算法和异构网络的数据帧协议。该系统网络平台融合了安防等其他系统,仿真试验表明,该系统网络冗余算法可靠性高,稳定性好。Aiming at the issues of low integration and the limitation of network compatibility for the instruments in water and sewerage company, this paper discusses the development of a multi-network access automatic control system based on Microchip processor PIC32 MX795 F512 L with the M4K core architecture, and expounds its whole system scheme, Ethernet/CAN network redundancy algorithm, and the frame protocols of heterogeneous network. Moreover, the system combines with other systems such as the safety protection system. Test results show that the network redundancy algorithm is effective, and that the proposed scheme of automatic control system is reliable and robust.
