Front Service Adaptation and Fault Diagnosis Device for Industrial Cyber-Physical Systems

Abstract

The invention discloses a prepositioned service adaption and fault diagnosis device for an industrial information physical system. The device comprises a port, a collection and conversion module, a fault diagnosis module and a service adaption module; the port includes different types of interfaces which are in connection and communication with industrial equipment of different interface types; according to the interface type of the industrial equipment, the collection and conversion module loads a bottom protocol adapted to the interface type so as to obtain operation state parameters of the industrial equipment; according to the collected operation state parameters, the fault diagnosis module predicts a fault type of the industrial equipment and generates a fault diagnosis result; and the service adaption module adapts instruction-oriented control into standard service oriented access dynamically. Thus, the operation state data, fault type and control function of the industrial equipment are made into services, an access interface is provided for the external via a standard Web service, the bottom heterogeneous communication protocols are shielded, and faults are predicted in real time and diagnosed in a classified way.

Description

technical field [0001] The invention belongs to the technical field of industrial information physical interconnection, and in particular relates to a device management and state monitoring technology used in industrial sites. Background technique [0002] In the cyber-physical system (CPS) architecture of manufacturing enterprises, there are many differences in data format and communication protocol between the bottom field control layer and the middle execution layer. In the actual production process, there are many types and quantities of industrial equipment, and it is necessary to design and support a variety of different access methods according to the user's needs for the interconnection and intercommunication of different field devices and control systems. For example: the connection protocols of the bottom field control layer mainly include OPC, DDE, ModBus, etc., while the middle execution layer mostly supports ODBC, XML and other protocols. However, for the front...

Problems solved by technology

However, for the front-end terminals currently used in industrial sites, in order to solve the problems of device communication and protocol conversion, it is usually necessary to design a communication gateway for specific underlying devices and applications, so the versatility is poor, and it is impossible to implement a front-end The terminal is compatible with various underlying devices

[0003] In addition, the existing front-end terminals can generally only complete end-to-end data collection and protocol conversion, and cannot perform statistical analysis, model construction and optimization on the collected data. Generally, the collected historical data needs to be uploaded to the background server for troubleshooting. Type comparison, so the function is single, the real-time performance is poor, and it is impossible to realize real-time on-site troubleshooting and early warning for industrial equipment
