Abstract

The invention provides a failure diagnosis system for process industrial dispersion type equipment failure diagnosis system. The system comprises an embedded signal acquisition processing unit and a rThe invention provides a failure diagnosis system for process industrial dispersion type equipment failure diagnosis system. The system comprises an embedded signal acquisition processing unit and a remote failure diagnosis system, wherein the embedded signal acquisition processing unit is connected with the dispersion type equipment; the remote failure diagnosis system is in networking connectionemote failure diagnosis system, wherein the embedded signal acquisition processing unit is connected with the dispersion type equipment; the remote failure diagnosis system is in networking connection with the embedded signal acquisition processing unit; the embedded signal acquisition processing system transmits an acquired equipment signal to the remote failure diagnosis system; the remote failuwith the embedded signal acquisition processing unit; the embedded signal acquisition processing system transmits an acquired equipment signal to the remote failure diagnosis system; the remote failure diagnosis system expresses the relationships among equipments in node definition information by a multilevel multistage flow model building mode, and transmits the node definition information to eare diagnosis system expresses the relationships among equipments in node definition information by a multilevel multistage flow model building mode, and transmits the node definition information to each embedded signal acquisition processing unit; and the embedded signal acquisition processing unit establishes a failure derivation relationship according to the received node definition information,ch embedded signal acquisition processing unit; and the embedded signal acquisition processing unit establishes a failure derivation relationship according to the received node definition information,and transmits a failure source to the remote failure diagnosis system after the failure source is determined. In the embedded data acquisition and analysis system, failure derivation of the multileve and transmits a failure source to the remote failure diagnosis system after the failure source is determined. In the embedded data acquisition and analysis system, failure derivation of the multilevel flow models is applied, and quick searching of the failure source in the embedded system can be realized by a simple matrix operation method, thereby so as to realizing realize quick analysis and pol flow models is applied, and quick searching of the failure source in the embedded system can be realized by a simple matrix operation method, thereby so as to realizing realize quick analysis and position the positioning on failures of a complicated distributed electromechanical device.sition the positioning on failures of a complicated distributed electromechanical device.

Description

technical field [0001] The invention relates to a device fault diagnosis system, in particular to a distributed device fault diagnosis system, which is applied to the fault diagnosis of process industry electromechanical devices. Background technique [0002] With the development of modern industry and science and technology and the further improvement of automation, the production units in the process industry are developing in the direction of large-scale, high-speed, continuous, centralized, and automated. Their main characteristics are that there are many equipment links and All equipment links are interrelated, and the connection between equipment is getting closer and closer. Once a device fails, the system will transmit the fault to another device through material flow, energy flow, and information flow, causing the entire production process to be paralyzed. If the fault cannot be diagnosed and eliminated in time, it will cause a major accident, so fault diagnosis is...
