Description

Technical Field

[0001] This invention relates to the technical field of lubricating oil stations, and in particular to an automatic heating auxiliary method and device for lubricating oil in lubricating oil stations suitable for harsh climates. Background Technology

[0002] In winter or other harsh weather conditions that result in low temperatures, the lubricating effect of lubricating oil is extremely poor. Therefore, lubricating oil needs to be preheated to a certain temperature before it can be used.

[0003] Existing lubricating oil temperature heating methods directly heat the lubricating oil in the tank. Once the oil in the tank reaches a preset temperature, the lubricating oil pump is activated. However, although the oil in the tank is heated to a suitable temperature, the lubricating oil in the pipeline remains at a lower temperature because it cannot be heated. Activating the lubricating oil pump under these conditions could cause damage to the pump and related equipment. Summary of the Invention

[0004] The purpose of this invention is to at least address one of the shortcomings of the prior art and to provide an automatic heating auxiliary method and device for lubricating oil stations that is suitable for harsh climates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Specifically, an automatic heating auxiliary method for lubricating oil in lubrication stations suitable for harsh weather conditions is proposed, including the following: Request a lubricant usage request; When a request to use lubricating oil is received, the real-time temperature (Temp) inside the lubricating oil tank is obtained. Determine whether the temperature Temp is lower than a first threshold. If so, enter automatic heating mode until the temperature Temp is not lower than the first threshold and then start the lubricating oil pump. Otherwise, start the lubricating oil pump directly. In the automatic heating mode, the electric heating device is controlled to continuously heat the lubricating oil tank, and the lubricating oil pump is controlled to repeatedly start and stop in a manner that stops for a duration of T1 and starts for a duration of T2.

[0006] Furthermore, specifically, the duration T1 is a first fixed value, the duration T2 is a second fixed value, T1 and T2 together constitute a cycle, and the duration ratio of T1 and T2 within the cycle is determined through prior experimental analysis.

[0007] Furthermore, specifically, the duration T1 and duration T2 together constitute a cycle. Multiple adjustment schemes are pre-set based on the proportion of duration T1 within the cycle. The adjustment schemes are sorted in descending order of the proportion of duration T1 within the cycle to obtain multiple adjustment schemes with different levels. The greater the proportion of duration T1 within the cycle, the smaller the level number. The level of the adjustment scheme is continuously increased according to the real-time temperature Temp change in the lubricating oil tank until the heating of the lubricating oil tank is completed.

[0008] Furthermore, specifically, the adjustment scheme is continuously increased based on the real-time temperature (Temp) changes within the lubricating oil tank, including: Within the cycle of any gear adjustment scheme, the real-time temperature Temp inside the lubricating oil tank is sampled at the same time interval to obtain N real-time temperatures Tempi, where i is [1, N]. Calculate the temperature difference between any two adjacent Tempi real-time temperature sampling points, and average all the obtained temperature differences to obtain the temperature change trend of the current adjustment scheme. Determine whether the temperature change trend is greater than the second threshold. If so, adjust the current adjustment scheme to one level with a larger sequence number. Otherwise, continue to run the current adjustment scheme for one cycle.

[0009] Furthermore, the method also includes generating a log file after each entry into the automatic heating mode and completion of the lubricating oil pump startup. The log file is used to record relevant data information collected during the entire lubricating oil startup process.

[0010] This invention also proposes an automatic heating auxiliary device for lubricating oil in a lubricating oil station suitable for harsh weather conditions, comprising: Use the request retrieval module to retrieve lubricant usage requests; The temperature data acquisition module is used to acquire the real-time temperature (Temp) inside the lubricating oil tank when a lubricating oil usage request is received. The lubricating oil pump control module is used to determine whether the temperature Temp is lower than a first threshold. If so, it enters the automatic heating mode until the temperature Temp is not lower than the first threshold and then starts the lubricating oil pump. Otherwise, it starts the lubricating oil pump directly. In the automatic heating mode, the electric heating device is controlled to continuously heat the lubricating oil tank, and the lubricating oil pump is controlled to repeatedly start and stop in a manner that stops for a duration of T1 and starts for a duration of T2.

[0011] Furthermore, specifically, the duration T1 is a first fixed value, the duration T2 is a second fixed value, T1 and T2 together constitute a cycle, and the duration ratio of T1 and T2 within the cycle is determined through prior experimental analysis.

[0012] Furthermore, specifically, the duration T1 and duration T2 together constitute a cycle. Multiple adjustment schemes are pre-set based on the proportion of duration T1 within the cycle. The adjustment schemes are sorted in descending order of the proportion of duration T1 within the cycle to obtain multiple adjustment schemes with different levels. The greater the proportion of duration T1 within the cycle, the smaller the level number. The level of the adjustment scheme is continuously increased according to the real-time temperature Temp change in the lubricating oil tank until the heating of the lubricating oil tank is completed.

[0013] Furthermore, the device also includes, The log file generation module is used to generate a log file each time the automatic heating mode is entered and the lubricating oil pump is started. The log file is used to record the relevant data information collected during the entire lubricating oil start-up process.

[0014] The present invention also proposes a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the automatic heating auxiliary method for lubricating oil suitable for harsh climates in the lubricating oil station.

[0015] The beneficial effects of this invention are as follows: This invention proposes an automatic heating auxiliary method for lubricating oil in a lubrication station suitable for harsh climates. When lubricating oil is needed, the method first determines whether the temperature in the lubricating oil tank is lower than a preset value. If so, the lubricating oil tank will be heated through a preset automatic heating mode. By repeatedly starting and stopping the lubricating oil pump, the lubricating oil in the tank and the lubricating oil in the oil pipe will continuously exchange heat, eventually making the oil temperature in the tank and the oil temperature in the oil pipe consistent. This not only effectively shortens the heating time but also protects the oil pump. Attached Figure Description

[0016] The above and other features of this disclosure will become more apparent from the detailed description of the embodiments illustrated in conjunction with the accompanying drawings. In the accompanying drawings, the same reference numerals denote the same or similar elements. Obviously, the drawings described below are merely some embodiments of this disclosure. For those skilled in the art, other drawings can be obtained from these drawings without any creative effort. In the drawings: Figure 1 The diagram shows a flowchart of the automatic heating auxiliary method for lubricating oil stations applicable to harsh climates according to the present invention.

Detailed Implementation

[0017] The following will provide a clear and complete description of the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The same reference numerals used throughout the accompanying drawings indicate the same or similar parts.

[0018] Reference Figure 1 as well as Figure 2 Example 1: This invention proposes an automatic heating auxiliary method for lubricating oil in a lubricating oil station suitable for harsh climates, comprising the following: Step 110: Obtain a lubricant usage request; Step 120: When a lubricating oil usage request is received, obtain the real-time temperature (Temp) inside the lubricating oil tank; Step 130: Determine whether the temperature Temp is lower than the first threshold. If so, enter the automatic heating mode until the temperature Temp is not lower than the first threshold and then start the lubricating oil pump. Otherwise, start the lubricating oil pump directly. In the automatic heating mode, the electric heating device is controlled to continuously heat the lubricating oil tank, and the lubricating oil pump is controlled to repeatedly start and stop in a manner that stops for a duration of T1 and starts for a duration of T2.

[0019] In this embodiment 1, when lubricating oil is needed, it is first determined whether the temperature in the lubricating oil tank is lower than the preset value. If so, the lubricating oil tank will be heated through a preset automatic heating mode. By repeatedly starting and stopping the lubricating oil pump, the lubricating oil in the tank and the lubricating oil in the oil pipe will continuously exchange heat, eventually making the oil temperature in the tank and the oil temperature in the oil pipe consistent. This not only effectively shortens the heating time but also protects the oil pump well. Since it is difficult to install a temperature sensor in the oil pipe for temperature measurement with current technology, the temperature can only be obtained by arranging a temperature sensor in the oil tank and matching the lubricating oil temperature in the oil pipe through the above processing. Figure 2 The diagram provided is a schematic of the automatic heating mode in a partial cycle, for your understanding.

[0020] In a preferred embodiment of the present invention, specifically, the duration T1 is a first fixed value, the duration T2 is a second fixed value, T1 and T2 together constitute a cycle, and the duration ratio of T1 and T2 within the cycle is determined by prior experimental analysis.

[0021] In this preferred embodiment, the durations T1 and T2 are set as constants, and a suitable value for T1 and T2 is found through extensive experiments. Although this can achieve the target heating, the temperature difference between the oil tank and the oil pipe decreases at a relatively gradual rate due to the continuous electric heating. At this time, if the stopping time of the lubricating oil pump is appropriately shortened and the starting time of the lubricating oil pump is appropriately extended, not only can the heating time be shortened, but the heating effect can also be enhanced.

[0022] Therefore, as another preferred embodiment of the present invention, specifically, the duration T1 and duration T2 together constitute a cycle. Multiple adjustment schemes are preset based on the proportion of duration T1 within the cycle, and the adjustment schemes are sorted according to the descending order of the proportion of duration T1 within the cycle to obtain multiple adjustment schemes with different levels. The greater the proportion of duration T1 within the cycle, the smaller the level number. The level of the adjustment scheme is continuously increased according to the real-time temperature Temp change in the lubricating oil tank until the heating of the lubricating oil tank is completed.

[0023] Specifically, the adjustment scheme is continuously increased based on the real-time temperature (Temp) changes within the lubricating oil tank, including: Within the cycle of any gear adjustment scheme, the real-time temperature Temp inside the lubricating oil tank is sampled at the same time interval to obtain N real-time temperatures Tempi, where i is [1, N]. Calculate the temperature difference between any two adjacent Tempi real-time temperature sampling points, and average all the obtained temperature differences to obtain the temperature change trend of the current adjustment scheme. Determine whether the temperature change trend is greater than the second threshold. If so, adjust the current adjustment scheme to one level with a larger sequence number. Otherwise, continue to run the current adjustment scheme for one cycle.

[0024] In this preferred embodiment, the schemes composed of different durations T1 and T2 are sorted and formed into levels by using the stopping time T1 of the lubricating oil pump as the standard. By measuring the temperature change trend in each level, if the temperature change trend is large enough, that is, greater than the second threshold, it means that the stopping time T1 of the lubricating oil pump does not need to be too long, so the level is increased by one level, slightly reducing the stopping time of the lubricating oil pump in one cycle and increasing the starting time of the lubricating oil pump. This not only shortens the heating time, but also enhances the heating effect.

[0025] In a preferred embodiment of the present invention, the method further includes generating a log file after each entry into the automatic heating mode and completion of the lubricating oil pump startup. The log file is used to record relevant data information collected during the entire lubricating oil startup process.

[0026] In this preferred embodiment, considering the administrator's management needs, the relevant data of the automatic heating mode is generated into a log file for the administrator to analyze and verify, so as to better optimize the system.

[0027] This invention also proposes an automatic heating auxiliary device for lubricating oil in a lubricating oil station suitable for harsh weather conditions, comprising: Use the request retrieval module to retrieve lubricant usage requests; The temperature data acquisition module is used to acquire the real-time temperature (Temp) inside the lubricating oil tank when a lubricating oil usage request is received. The lubricating oil pump control module is used to determine whether the temperature Temp is lower than a first threshold. If so, it enters the automatic heating mode until the temperature Temp is not lower than the first threshold and then starts the lubricating oil pump. Otherwise, it starts the lubricating oil pump directly. In the automatic heating mode, the electric heating device is controlled to continuously heat the lubricating oil tank, and the lubricating oil pump is controlled to repeatedly start and stop in a manner that stops for a duration of T1 and starts for a duration of T2.

[0028] In a preferred embodiment of the present invention, specifically, the duration T1 is a first fixed value, the duration T2 is a second fixed value, T1 and T2 together constitute a cycle, and the duration ratio of T1 and T2 within the cycle is determined by prior experimental analysis.

The greater the proportion of duration T1 within the cycle, the smaller the level number. The level of the adjustment scheme is continuously increased according to the real-time temperature Temp change in the lubricating oil tank until the heating of the lubricating oil tank is completed.
