Network online reconfigurable industrial security monitoring system

Abstract

The invention discloses a network online reconfigurable industrial security monitoring system. The system includes a network monitoring man-machine interaction interface, a network monitoring unit and a network control unit; the network monitoring unit is composed of a Modbus monitoring master station which includes two monitoring master stations of different industrial control network types, and a Modbus slave station which includes two industrial control networks dynamically and partially-reconfigurable field apparatuses, wherein the monitoring master station can be put into operation in a switchable manner, and the field apparatuses are a gateway and a Modbus access control system control station respectively; the network monitoring unit is composed of a CAN control network; and the CAN control network includes three field control stations which are respectively used for monitoring field temperature and humidity, smoke concentration and warning. The network online reconfigurable industrial security monitoring system of the invention can automatically identify network types, plan reconfiguration plans, complete network communication dynamical local reconfiguration, and can automatically adapt to the change of different industrial control network types under the constraint that the continuous uninterrupted operation and the detection and control function of the whole system are not affected assuredly and control quality does not change; and the network online reconfigurable industrial security monitoring system has revolutionary significance in the industrial automatic control filed.

Description

technical field [0001] The invention belongs to the field of industrial automatic control, in particular to an industrial safety monitoring system based on an online partial reconstruction method. Background technique [0002] At present, the network control system is the main form of the control system in the information age, and the network control nodes are interconnected through the communication medium according to a certain communication protocol. Due to the diversity of the application objects controlled by the network control system and the unpredictability of the application environment, the network control system designed by the traditional design method cannot adapt to the changes of the application objects and the environment. If the compatible objects and environments are considered, the cost of designing a networked control system is too high. In addition, the network control system does not have a unified communication protocol standard, that is, multiple com...

However, static global reconfiguration requires reconfiguration of the entire FPGA resource. This reconfiguration method is to update and write the entire device, and some functions that do not need to be reconfigured are also updated and written, resulting in reinitialization of the system. When the network is reconfigured, other functions and other communications will also be suspended. After the system initialization is completed, all acquisition, control, and communication will be re-established, which will affect the stable operation of the non-reconfigured part, so this technology has not been widely used in industry. During on-site control
