Iron and steel continuous casting equipment oriented method and device for forecasting faults

Abstract

The invention relates to an iron and steel continuous casting equipment oriented method and device for forecasting faults. The device is characterized in that sensors installed on iron and steel continuous casting equipment are used for acquiring real-time status parameters of the equipment; the signals are processed by signal conditioning circuits, amplifying and filtering circuits and A/D conversion modules of data acquisition nodes and the data are sent to handheld spot inspection equipment via radio circuits supporting the Zigbee protocols; the handheld spot inspection equipment receives and analyzes the data; eigenvectors of equipment status data are constructed based on decomposition and construction carried out by wavelet packets, the eigenvectors are used as samples, support vector data description is utilized to train a single-value classifier, and the domesticated classifier is utilized to compute the health index of the equipment and describe the deterioration curve of the equipment so as to further forecast the residual service life of the equipment; the data acquisition node main boards comprise the sensors, the signal conditioning circuits, the amplifying and filtering circuits, single chips and antenna circuits; and the handheld spot inspection equipment comprises a radio communication module, an advanced RISC machines (ARM) minimum system, a keyboard and a display module. The method and the device have the beneficial effects of adopting the radio communication mode and abandoning the traditional industrial buses, being applied in the harsh production equipment such as iron and steel continuous casting lines, reducing the trouble of arranging lines and lowering the application cost.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis and prediction of mechanical equipment, and in particular relates to a fault prediction method and device for iron and steel continuous casting equipment. Background technique [0002] The demand for equipment maintenance management services in the domestic manufacturing industry continues to rise. There is an urgent need to develop an MRO support system for large-scale equipment, to provide comprehensive digital solutions and information integration technologies for equipment manufacturers, equipment users and equipment service companies, and to promote the leapfrog development of the manufacturing service industry. At present, domestic iron and steel continuous casting production lines still adopt the maintenance mode of after-event maintenance and planned maintenance. The maintenance costs are high, and unplanned shutdowns of equipment are prone to occur, causing huge losses. Tradition...
