DETAILED DESCRIPTION

[0019] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. Unless there is a conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0020] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects. Example 1

[0021] Figure 1 This is a flow chart of a lubrication system maintenance method in the first embodiment of the present invention. This flow chart only shows the logical sequence of the method described in this embodiment. In other possible embodiments of the present invention, different methods may be used without conflict. Figure 1 The steps shown or described are accomplished in the order shown.

[0022] The lubrication system maintenance method provided in this embodiment can be applied to the terminal. Figure 2 The whole machine controller 7 is executed, for example: vehicle VCU, vehicle computer chip, single chip microcomputer. Figure 1 , the method of this implementation specifically includes the following steps: Obtaining a mass measurement value of lubricating oil in a working component 12 requiring lubrication, and in response to the mass measurement value exceeding an acceptable range, outputting a first visual alarm signal based on the component number of the working component 12 requiring lubrication and the mass measurement value; Obtaining a first liquid level value of the lubricating oil in the working component requiring lubrication, and outputting a lubricating oil injection signal in response to the first liquid level value being lower than a liquid level threshold, wherein the lubricating oil injection signal is used to control the electronically controlled valve component 15 to inject lubricating oil into the working component requiring lubrication 12; The pressure difference value on both sides of the filter membrane of the lubricating oil filter component 13 is obtained, and in response to the pressure difference value exceeding the pressure difference threshold, a second visual alarm signal is output according to the component number of the lubricating oil filter component 13 and the pressure difference value.

[0023] The maintenance method for the lubrication system provided in this embodiment integrates multiple sensor data, realizes automatic early warning and automatic lubricating oil filling, and improves the convenience of checking the internal operating status of the lubrication system; in addition, this method also follows the priority principle of "lubricating oil quality > lubricating oil level > lubricating oil filter component performance", and puts the quality measurement value that directly affects the safety of engineering equipment as the first priority. Once the quality measurement value exceeds the qualified range, a visual early warning can be given; the second is the first liquid level value, which is related to the use time of the engineering equipment, and automatic filling is performed when the stored lubricating oil is sufficient; finally, the pressure difference value on both sides of the filter membrane of the lubricating oil filter component 13 is used to determine whether the engineering equipment needs to be shut down for maintenance by analyzing the pressure difference value. Example 2

[0024] This embodiment provides a maintenance method for a lubrication system. This embodiment is optimized based on the first embodiment to improve the technical effect and refine the technical solution. For details not fully described in this embodiment, please refer to the first embodiment.

[0025] In one embodiment, the quality measurements include lubricant viscosity, trace moisture content, water content, contamination level, metal abrasive content, and dielectric constant. If any of these quality measurements exceeds a specified range, the corresponding quality measurement type, value, and prompt are integrated into a first visual alarm output, which is displayed on the in-cab screen, voice system, or other devices.

[0026] After receiving the lubricating oil injection signal, the electronically controlled valve component 15 injects the stored lubricating oil into the working component 12 to be lubricated. However, the amount of stored lubricating oil may not be enough to make the first liquid level value in the working component 12 to be lubricated reach the liquid level threshold. Therefore, a step should be designed: As mentioned in the first embodiment, obtaining a first liquid level value of the lubricating oil in the working component to be lubricated, and outputting a lubricating oil injection signal in response to the first liquid level value being lower than a liquid level threshold, includes: In response to the first liquid level value being lower than a liquid level threshold; Obtaining a first difference between the first liquid level value and the liquid level threshold, and obtaining a first refueling value according to the first difference and a preset additional refueling coefficient; Obtain the second liquid level value of storage tank 1; In response to the second liquid level value being greater than or equal to the first refueling value, using the first refueling value as refueling quantity data in the lubricating oil injection signal; In response to the second liquid level value being less than the first refueling value, using the second liquid level value as refueling quantity data in the lubricating oil injection signal, and outputting a third visual alarm signal; The refueling amount data is used to control the amount of lubricating oil injected by the electronically controlled valve component 15 into the working component 12 requiring lubrication.

[0027] The additional refueling coefficient is greater than 1. The purpose of setting the additional refueling coefficient is to prevent frequent triggering of refueling behavior.

[0028] This step is intended to judge the relationship between the first refueling value and the second liquid level value (i.e., the amount of remaining stored lubricant) to determine whether to automatically refuel the lubricant without the driver noticing; when the second liquid level value is greater than or equal to the first refueling value, it means that the remaining stored lubricant is sufficient, and the refueling of the lubricant is completed without disturbing the driver; when the second liquid level value is less than the first refueling value, it means that the remaining stored lubricant is insufficient, and all the remaining stored lubricant is injected into the working part 12 to be lubricated, and at the same time, the driver is reminded to refuel the lubricant by visually displaying a third visual alarm signal.

[0029] As one embodiment, an overflow threshold may be set. In response to the first liquid level reaching the overflow threshold, a lubricant injection stop signal is output. The lubricant injection stop signal is used to control the electronically controlled valve component 15 to stop injecting lubricant into the working component 12 requiring lubrication. Of course, the overflow threshold is greater than the liquid level threshold. Example 3

Figure 2 , including, a whole machine controller 7, the whole machine controller 7 is used to execute the maintenance method of the lubrication system described in embodiment 1 or 2; A liquid level sensor is electrically connected to the whole machine controller 7, and the whole machine controller 7 is used to detect a first liquid level value of the lubricating oil in the working part 12 to be lubricated; A lubricating oil monitoring and analyzing instrument 6 is electrically connected to the whole machine controller 7 and is used to measure the quality of the lubricating oil; The pressure difference sensor component 14 is electrically connected to the whole machine controller 7 and is used to detect the pressure difference value on both sides of the filter membrane of the lubricating oil filter component 13; The electric control valve component 15 is connected to the whole machine controller 7 by electrical signals.

[0031] As one embodiment, the human-computer interaction instrument 8 can be a touch screen in the cab, or a remote background operation terminal of an unmanned vehicle.

[0032] The maintenance method of the lubrication system provided in Example 1 or 2 can be applied to the maintenance system of the lubrication system provided in this embodiment, and has functional modules and beneficial effects corresponding to the execution method. The maintenance system of the lubrication system provided in this embodiment has the same technical effects as Example 1 or 2, and will not be repeated here. Example 4

[0033] This embodiment provides a maintenance system for a lubrication system. This embodiment is optimized based on the first embodiment to improve the technical effect and refine the technical solution. For details not fully described in this embodiment, please refer to the third embodiment.

[0034] As one example, refer to Figure 2 The installation height of the storage oil cylinder 1 exceeds the refueling port of the working part 12 that needs to be lubricated. In this way, when the electronically controlled valve component 15 is controlled to open, the lubricating oil in the storage oil cylinder 1 is automatically injected into the working part 12 that needs to be lubricated by gravity, reducing the design of the oil pump.

[0035] As one embodiment, the refueling port of the working component 12 requiring lubrication is a three-way refueling port, which is connected to the storage oil cylinder 1 and the outside world respectively, and lubricating oil can be added to the refueling port of the working component 12 requiring lubrication and / or the storage oil cylinder 1 from the outside world.

[0036] As one example, refer to Figure 2The lubricating oil filter component 13 is connected to the working component 12 requiring lubrication through a first flow channel. The inlet of the first flow channel is located at the lowest point in the working component 12 requiring lubrication, and the installation height of the lubricating oil filter component 13 is lower than the installation height of the working component 12 requiring lubrication.

[0037] Impurities contained in the lubricating oil in the working component 12 to be lubricated will gather at the lowest point in the working component 12 to be lubricated under the action of gravity, and enter the lubricating oil filter component 13 through the first flow channel for filtration.

[0038] As one example, refer to Figure 2 , The inlet of the lubricating oil monitoring and analyzing instrument 6 is connected to the outlet of the working component 12 to be lubricated. The lubricating oil monitoring and analyzing instrument 6 is used to measure the quality of the lubricating oil after being filtered by the lubricating oil filter component 13, which can be used to indirectly evaluate the filtering capacity of the lubricating oil filter component 13; The outlet of the lubricating oil monitoring and analyzing instrument 6 is connected to the oil filling port of the working component 12 that needs to be lubricated. The lubricating oil monitoring and analyzing instrument 6 is also provided with an oil pump for pumping lubricating oil.

[0039] The lubricating oil completes the filtration circulation path of "the lowest point of the working component 12 to be lubricated → the first flow channel → the lubricating oil filter component 13 → the lubricating oil monitoring analyzer 6 → the refueling port of the working component 12 to be lubricated".

[0040] As one example, refer to Figure 2 The working parts 12 that need lubrication include the engine 2 and the gearbox 3. Therefore, the maintenance system of the lubrication system in this embodiment is mainly divided into two sets with symmetrical functions.

[0041] The engine 2 and the transmission 3 share a fuel storage cylinder 1; the electronically controlled valve component 15 includes a first electronically controlled valve 9 and a second electronically controlled valve 10, both of which are series electronically controlled valves; the fuel filling port of the engine 2 is a first fuel filling port 11.1, and the fuel filling port of the transmission 3 is a second fuel filling port 11.2, both of which are three-way fuel filling ports; the fuel storage cylinder 1 is connected to the first fuel filling port 11.1 and the second fuel filling port 11.2 through two flow channels, and the first electronically controlled valve 9 and the second electronically controlled valve 10 are respectively arranged on the first fuel filling port 11.1 and the second fuel filling port 11.2.

[0042] The liquid level sensors include a first liquid level sensor 201 and a second liquid level sensor 301. The first liquid level sensor 201 is provided within the engine 2 to detect a first liquid level within the engine 2, and the second liquid level sensor 301 is provided within the transmission 3 to detect a first liquid level within the transmission 3. The first liquid level sensor 201 and the second liquid level sensor 301 are each electrically connected to the machine controller 7.

[0043] The lubricating oil filter component 13 includes a first lubricating oil filter 4 and a second lubricating oil filter 5. The first lubricating oil filter 4 is connected to the engine 2, and the second lubricating oil filter 5 is connected to the transmission 3. The differential pressure sensing component 14 includes a first differential pressure sensor 401 and a second differential pressure sensor 501. The first differential pressure sensor 401 is located on the filter membrane of the first lubricating oil filter 4, and the second differential pressure sensor 501 is located on the filter membrane of the second differential pressure sensor 501.

[0044] The first lubricating oil filter 4 and the second lubricating oil filter 5 share the same lubricating oil monitoring analyzer 6 .

[0045] As one example, refer to Figure 2 Most of the lubricating oil from the first lubricating oil filter 4 flows directly back into the engine 2, and a small part enters the lubricating oil monitoring analyzer 6 through a bypass for detection, and then flows back to the engine 2; the relationship between the second lubricating oil filter 5 and the lubricating oil monitoring analyzer 6 is the same as that of the first lubricating oil filter 4.

[0046] As one embodiment, a data storage module is further included, which is electrically connected to the whole machine controller 7 and is used to store data and process logs.

[0047] The maintenance system of the lubrication system provided in this embodiment improves work efficiency, realizes the automation of lubricating oil detection and filling, reduces downtime, and improves work efficiency; ensures equipment safety, monitors the lubricating oil status in real time, promptly discovers potential problems, and avoids equipment damage; improves detection accuracy, adopts automatic detection by sensors, avoids human errors, and improves detection accuracy; realizes data recording, automatically records lubricating oil usage data, and facilitates equipment maintenance and management; reduces maintenance costs, extends the service life of lubricating oil, reduces the replacement frequency of lubricating oil and filter element, and reduces maintenance costs.
