This paper is focused on the measure and control system for large pumping station auxiliary equipments. The design of system has advantages as follows, functions of sensing measure, compensation calculation and policy control are decentralized to the intelligent measure and control equipments in the field improve stability and reliability of the system; digitalized application eliminates the analog signal transmission errors and fundamentally improves the accuracy of measure and control; CAN-Bus has a higher data transfer rate and distribution capacity of bus resources; isolated CAN-Bus design makes the system anti-overvoltage ability strong; simple requirements of communication network wiring highlight the economy of the system. The application of the system is also described in the paper.

A distributed cross-direction control system based on CAN-bus was designed to solve the large-scale cross-direction control problem for paper machine. Multiple Master-Slave CAN networks were constructed in parallel to coordinate and control multiple array actuators, and the Ethernet/CAN converter was used to connect the monitoring station with the field intelligent actuators. The monitoring station accesses measured data and field data via OPC technology. A CAN application layer protocol and corresponding underlying communication software were designed according to the characteristics of the cross-direction control processes. Finally, the feasibility and reliability of the system were verified with practical applications.

The monitoring and control system based on CAN bus was designed in order to implement the data reliable transmission between all nodes in the control system of the vehicle-mounted rig. Firstly, the hardware structure of the monitoring system was designed in the paper, and two CAN network was built, which one CAN network used CANopen protocol and the other used J1939 protocol and CAN2.0B protocol, that it saved the resource of hardware and software. Secondly, all CAN protocols , program flow chart and software with Labview were designed in detail. The application results of the actual engineering showed that it realized the function of data transmission with each console and real-time monitoring.

Reliability is one of the most important properties of integrated supervisory and control system (ISCS) in metro. Redundancy technology, a fault tolerant mechanism, can significantly improve ISCS reliability. This paper introduces a redundancy design schema and its implementation in distributed real-time database, which is the kernel part of ISCS, Including upstream and downstream data redundancy processing technology, fault detection and redundancy switch technology. The result shows that this schema is feasible and reasonable.
