Description

Technical Field

[0001] This invention relates to anomaly monitoring technology, and more specifically, to a method for monitoring and early warning of abnormal lubricating oil consumption. Background Technology

[0002] As the various actuators of the conveying system (such as rotating shafts and motor gearboxes) wear and age, their lubrication systems will inevitably experience some degree of hidden oil leakage, leading to insufficient lubrication at the lubrication points. Because the amount of hidden oil leakage is small and there are many lubrication points on site, it is difficult for on-site personnel to detect it in a timely manner. Furthermore, when hidden oil leakage occurs, the oil level detection system in the lubrication point reports the insufficient oil level to the lubrication system, which then tries to correct the situation by increasing the oil level. However, this approach only increases the amount of oil leaking at the hidden point, resulting in a waste of lubricating grease. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent method for monitoring and early warning of abnormal lubricating oil consumption, which effectively reminds on-site personnel and personnel in the monitoring room to deal with abnormal lubrication points in a timely manner, ensuring normal oil supply to each lubrication point on site, while reducing oil waste and protecting the site environment.

[0004] The present invention discloses an intelligent method for monitoring and early warning of abnormal lubricating oil consumption, which identifies and codes each lubrication point; when the lubrication system is running, the code of the lubrication point in operation is identified, and the real-time oil supply pressure of the lubrication point is obtained; the oil supply pressure of the lubrication point is judged according to the relationship between the real-time oil supply pressure and the set pressure threshold; if the real-time oil supply pressure is greater than or equal to the pressure threshold, the code corresponding to the lubrication point is marked as normal.

[0005] If the real-time oil supply pressure is less than the pressure threshold, the oil supply pressure of the lubrication point is further judged by the single-to-multi-point pressure comparison method. If it is normal, the code corresponding to the lubrication point is marked as normal; otherwise, the code corresponding to the lubrication point is marked as abnormal, and the abnormal warning mechanism is activated.

[0006] As a further improvement, the single-to-multipoint pressure comparison method is specifically as follows:

[0007] A data acquisition time is set. When the data acquisition time is reached, the second oil supply pressure of the lubrication point is acquired; the circulating oil supply pressure of the lubrication point is acquired.

[0008] The second oil supply pressure is compared with the pressure threshold and the circulating oil supply pressure is compared with the pressure threshold. If the second oil supply pressure and the circulating oil supply pressure are both greater than or equal to the pressure threshold, the code corresponding to the lubrication point is normally marked.

[0009] If the second oil supply pressure and the circulating oil supply pressure are both less than the pressure threshold, the code corresponding to the lubrication point will be marked as abnormal, and the abnormal warning mechanism will be activated.

[0010] If either the second oil supply pressure or the circulating oil supply pressure is less than the pressure threshold, and the other is greater than or equal to the pressure threshold, then the pre-abnormality warning mechanism is activated.

[0011] Furthermore, the data collection time is set in the following manner:

[0012] The lubrication start signal of the lubrication point is detected in real time; when the lubrication start signal arrives, a set delay time is initiated, and the end of the delay time is taken as the acquisition time arrival command.

[0013] Furthermore, while marking the code corresponding to the lubrication point as normal, the collected pressure value of the lubrication point is recorded and stored.

[0014] Furthermore, the abnormal warning mechanism involves displaying the abnormal code on the industrial control computer's screen and simultaneously activating an audible and visual alarm.

[0015] Furthermore, the pre-anomaly warning mechanism involves displaying the anomaly code on the industrial control computer's display screen.

[0016] Beneficial effects

[0017] The advantages of this invention are as follows: each lubrication point is coded and monitored when lubrication is started. By comparing the real-time oil supply pressure and the single-to-multi-point pressure, dual monitoring of the oil supply pressure at the lubrication point is achieved, reducing the probability of misjudgment and ensuring accurate monitoring of abnormal points. At the same time, through the abnormal early warning mechanism, the on-site staff and the staff in the monitoring room can be effectively reminded to deal with abnormal lubrication points in a timely manner, ensuring normal oil supply to each lubrication point on site, reducing grease waste, and protecting the site environment. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the monitoring and early warning method of the present invention. Detailed Implementation

[0019] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0020] See Figure 1 This invention discloses an intelligent method for monitoring and early warning of abnormal lubricating oil consumption, which identifies and codes each lubrication point. When the lubrication system is running, the code of the operating lubrication point is identified, and the real-time oil supply pressure of the lubrication point is obtained. The normality of the oil supply pressure of the lubrication point is determined based on the relationship between the real-time oil supply pressure and a set pressure threshold. If the real-time oil supply pressure is greater than or equal to the pressure threshold, the code corresponding to the lubrication point is marked as normal, and this can be identified as a normally lubricated location by highlighting the code in green. If the real-time oil supply pressure is less than the pressure threshold, the normality of the oil supply pressure of the lubrication point is further determined using a single-to-multi-point pressure comparison method. If it is normal, the code corresponding to the lubrication point is marked as normal; otherwise, the code corresponding to the lubrication point is marked as abnormal, and an abnormality early warning mechanism is activated. Specifically, the abnormal code is displayed on the industrial control computer screen, and an audible and visual alarm is activated to remind on-site personnel and personnel in the monitoring room to promptly address the abnormal fault at the lubrication point corresponding to the code, requiring maintenance personnel to handle it, ensuring normal oil supply to each lubrication point on-site, reducing grease waste, and protecting the on-site environment.

[0021] Specifically, the single-to-multipoint pressure comparison method is as follows:

[0022] Set a data collection time. When the time is up, collect the second oil supply pressure and the circulating oil supply pressure of the lubrication point. Compare the second oil supply pressure with a pressure threshold and the circulating oil supply pressure with a pressure threshold. If both the second oil supply pressure and the circulating oil supply pressure are greater than or equal to the pressure threshold, the code corresponding to the lubrication point is highlighted in green. The circulating oil supply pressure is the average of the oil supply pressures obtained from multiple data collections of the lubrication point.

[0023] If both the second oil supply pressure and the circulating oil supply pressure are lower than the pressure threshold, the code corresponding to the lubrication point will be marked as abnormal. This abnormality can be identified by highlighting the code in red, allowing staff to quickly and accurately locate the abnormal point. After marking, the abnormality warning mechanism will be activated to issue an alert.

[0024] If either the second oil supply pressure or the circulating oil supply pressure is less than the pressure threshold, while the other is greater than or equal to the pressure threshold, it indicates that the single oil supply pressure and multiple oil supply pressures at the same lubrication point are not the same, but there is a risk of lubrication leakage. Therefore, the pre-abnormality warning mechanism is activated. This involves displaying the abnormal code on the industrial control computer's screen and highlighting it in yellow to distinguish it from normal codes.

[0025] In this embodiment, the acquisition time is set as follows: the lubrication start signal of the lubrication point is detected in real time; when the lubrication start signal arrives, a set delay time is initiated, and the end of the delay time is used as the acquisition time arrival command. This delay time can be set to less than 100 milliseconds, the purpose of which is to avoid measuring the unstable lubricating oil supply pressure at the beginning of the oil supply, thereby improving the reliability of the acquired data.

[0026] While marking the corresponding code of the lubrication point as normal, the collected pressure values ​​of the lubrication point are recorded and stored for subsequent data traceability.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
