Intelligent oil-gas lubrication monitoring system and method

Abstract

The invention discloses an intelligent oil-gas lubrication monitoring system. The intelligent oil-gas lubrication monitoring system comprises a lubrication point state monitoring station, an oil-gas lubrication PLC, an industrial control computer, an intelligent vision sensor and a fuzzy controller, the fuzzy controller is used for processing oil-gas supply quantity parameter set values from the oil-gas lubrication PLC and oil film state data from the intelligent vision sensor, providing the oil-gas supply quantity parameter adjustment amount, adjusting oil-gas supply parameters of an oil-gas lubrication device, and evaluating whether the oil film state data meet predefined requirements, and therefore oil films meeting the predefined requirements of oil-gas lubrication are sprayed to all lubrication points. According to the intelligent oil-gas lubrication monitoring system, the intelligent vision sensor is used for directly collecting and processing oil film images, the corresponding oil film state data are extracted from pixels of the oil film images, and oil film state indexes are evaluated through the fuzzy controller and therefore meet the predefined requirements of oil-gas lubrication better. The invention further discloses an intelligent oil-gas lubrication monitoring method.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an oil-gas lubrication intelligent monitoring system. The invention relates to an intelligent monitoring method for oil-air lubrication. Background technique [0002] In recent years, oil-air lubrication technology has been widely used in metallurgical equipment such as wire and bar mills and continuous casting machines. The so-called oil-air lubrication means that under the action of compressed air, the lubricating oil is blown into a fine oil film around the inner wall of the pipeline, moves forward in a wave shape, and finally sprays to the lubrication point with an extremely fine continuous oil film. [0003] At present, there are many oil-air lubrication equipment on the market, but some of them are still far from the above-mentioned definition of oil-air lubrication. Incorrect oil-air supply setting value will form different oil films. If oil and gas are in the pipeline If the speed...

Problems solved by technology

However, in the actual operation of the lubrication system, the number of lubrication points and the working status are constantly changing, and the fixed oil and gas supply setting value cannot meet the requirements of the working conditions.

[0005] Chinese patent document 20110387632.4 discloses an electrical control system for oil-air lubrication. The lubricating oil detection sensor transmits the collected signal data to the PLC controller. Requirements; wherein the PLC controller cannot dynamically and automatically adjust the oil and gas supply parameters according to the working state of the lubrication point and the oil film state data

[0006] The commonly used means of monitoring the oil film is to use the flow monitor to monitor the air flow rate. When the flow rate is too low or the flow stops, the monitor will give an alarm. This can only obtain the information of whether the compressed air or lubricating oil in the pipeline is blocked, but for For the expensive lubricating point, in order to make it work continuously in a good lubricating state for a long time, it is not enough to keep the compressed air or lubricating oil unblocked. Even if the oil film that does not meet the requirements is sprayed to the lubricating point, it will not meet expectations lubricating effect, and cause energy waste

[0007] Chinese patent document 200480020550.4 discloses a method of monitoring an oil-air lubrication device by means of a schlieren sensor. By detecting the schlieren signal generated by the schlieren over time, it belongs to the indirect acquisition of the oil film schlieren signal and filtering calculation of the signal itself. A method, the operator cannot directly judge the schlieren signal
