Embodiment Construction

[0010] The fault diagnosis system of the present invention realizes the connection with the field equipment through the PLC control network; uses the digital technology to combine the physical manufacturing system into an information-based system to make it operate effectively; at the same time, realizes the equipment status monitoring with the help of multimedia audio-visual technology for diagnosis and control. Therefore, fault diagnosis has practical significance for the reliable, continuous and safe production of tread extrusion production process.

[0011] The present invention establishes a tree-shaped fault model aiming at external equipment faults, intelligent slave station faults, PLC system faults, and bus faults of the control system of the tread extrusion production line, and uses the above-mentioned faults as the root node of the upper-end event tree to directly generate system faults. The reason is used as the branch node of the lower-end event (intermediate even...

Abstract

The invention provides an intelligent fault diagnosis system in tread extrusion process. The intelligent fault diagnosis system comprises a tread extrusion production line fault diagnosis subsystem and a screw extruder fault diagnosis subsystem. The tread extrusion production line fault diagnosis subsystem comprises a system modeling module, a knowledge management module, an intelligent diagnosis module, a cooperation management and scheduling module, a data management and report module and a diagnosis expert management module; the screw extruder fault diagnosis subsystem comprises a data acquisition and detection module, a human-computer interface interaction system and a routine control layer; and the human-computer interface interaction system comprises a supervision and management layer and a parameter estimation module. The intelligent fault diagnosis system in the tread extrusion process can improve the degree of automation of the tread extrusion production line.

Description

technical field [0001] The invention relates to a fault diagnosis method for tread manufacturing equipment in the tire industry, in particular to an intelligent fault diagnosis method for production line operation in the tread extrusion process. Background technique [0002] The continuous and rapid growth of the automobile industry has greatly driven the rapid development of the tire manufacturing industry. As an essential part of a car, tires play an important role in the performance, quality and safety of the vehicle. To ensure the quality, output and safety of equipment and personnel in tire production, condition monitoring and fault diagnosis of its manufacturing equipment is a very important link. The status monitoring and fault diagnosis of tread extrusion equipment is to grasp the status of the equipment during operation, evaluate and predict the reliability of the equipment, find faults early, identify the causes, locations, and degree of danger, and forecast faul...
