[0002] Due to the contradiction between the growing demand for household storage and limited space, storage bed frames have become a key solution for optimizing space utilization. By constructing a storage space under the bed to accommodate storage boxes, it significantly increases storage capacity. To further improve the user's retrieval experience, modern smart storage bed frames are usually equipped with an automatic retrieval function - after receiving the control command, the storage box automatically moves along the preset track to the retrieval port. The reliability of this function is highly dependent on the track, but in long-term use, the track often increases in friction coefficient due to factors such as dust intrusion and lubrication degradation, thus affecting the normal use of the automatic retrieval function.

For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0030] Modern smart storage bed frames often feature an automatic access function. Upon receiving a control command, the storage compartment automatically moves along a preset track to the access opening. The reliability of this function is highly dependent on the track. However, over time, factors such as dust intrusion and lubrication degradation often cause the track's friction coefficient to increase, thus affecting the proper function of the automatic access function.

[0031] In view of this, an embodiment of the present application provides a track maintenance method for a smart bed frame, the smart bed frame comprising a support frame, an oil replenishing device, and a track. A storage space for placing multiple storage boxes is formed below the support frame. The track is disposed on the support frame and is used to guide each storage box to move along a preset movement path.

The method comprises: obtaining movement data of the multiple storage boxes; determining a degree of friction of the track based on the movement data of the multiple storage boxes; determining operating parameters of the oil replenishing device based on the degree of friction of the track, the operating parameters being used to control an oil output of the oil replenishing device, the oil output being positively correlated with the degree of friction of the track; and controlling the oil replenishing device to deliver lubricating oil to the target lubrication point in the track through the at least one oil outlet based on the operating parameters. It can be seen that the degree of friction of the track is determined based on the movement data of the multiple storage boxes, and then based on the degree of friction of the track, a total oil replenishment amount that meets the current track oil replenishment requirements can be accurately determined. Based on the total oil replenishment amount, the operating parameters of the oil replenishment device are determined, and based on the operating parameters, the oil replenishment device is controlled to output lubricating oil to the target lubrication point in the track through at least one oil outlet, which can not only realize automatic track oil replenishment, but also realize precise control of the oil replenishment amount: effectively avoid the problem of lubricating oil blocking the track and affecting the movement of the storage box due to excessive oil replenishment, and effectively avoid the problem of excessive lubricating oil dripping into the storage box, resulting in poor user experience, and also effectively avoid the problem of failing to achieve the purpose of track life maintenance due to insufficient oil replenishment.

[0032] In order to better understand the track maintenance method provided in the embodiment of the present application, the structure of the smart bed frame is schematically illustrated below.

[0033] See Figure 1 , is a structural diagram of a smart bed frame provided in an embodiment of the present application. Figure 1 As shown, the smart bed frame includes a support frame 110, an oil replenishing device 120 and a track 130. It should be noted that, Figure 1 (a) is a side view of the smart bed frame, and (b) is a top view of the smart bed frame.

[0034] A storage space for a plurality of storage boxes 140 is formed below the support frame 110. It should be noted that: Figure 1 In the figure, one storage box 140 is used as an example, but in reality, there can be multiple storage boxes, for example, 2-8. Figure 2 , is a schematic diagram of the distribution of multiple storage boxes in a smart bed frame provided by an embodiment of the present application. Figure 2 As shown, the smart bed frame includes 8 storage boxes 140.

[0035] Optionally, each storage box 140 may be provided with a drive device, which includes rollers disposed below the storage box, a drive motor for providing power to move each storage box 140, and a sliding device connected to the track. Optionally, each storage box 140 may be provided with a weight sensor, which can be used to measure the weight of each storage box 140, and thus indirectly measure the weight of the items contained in each storage box 140. Since the weight of each storage box 140 is related to the movement speed of each storage box 140, the weight of each storage box 140 is measured in real time based on the weight sensor, so that the movement speed of each storage box 140 can be accurately obtained, thereby calculating the reference movement time of each storage box 140. Optionally, each storage box 140 may be provided with a communication module. The communication device may include at least one of a wireless communication technology (e.g., WiFi) module, a Bluetooth module, a near field communication (NFC) module, or other network communication protocol chip or near field communication protocol chip, as well as an infrared receiver. Each storage box 140 may communicate with a user device, a track maintenance device, a server, etc. via the communication module. A user device is a device used by a user to control the smart bed frame, such as a terminal device. Terminal devices include, but are not limited to, mobile phones, personal computers (PCs), tablet computers, laptop computers, PDAs, and mobile internet devices (MIDs).

[0036] The oil replenishing device 120 includes at least one oil outlet provided at a target lubrication point of the track 130. The oil replenishing device is used to deliver lubricating oil to the target lubrication point through the at least one oil outlet. The target lubrication point can be any end point, an intermediate point, or any position where a lubrication point can be provided in the track. This embodiment of the present application is not limited to this. For a better understanding of the structure of the oil replenishing device 120, please refer to Figure 3 , is a structural diagram of an oil replenishing device provided in an embodiment of the present application. Figure 3 As shown, the oil replenishing device 120 may include an oil replenishing pump 121 and an oil storage bottle 122. The oil replenishing pump 121 is used to output lubricating oil. For example, the oil replenishing pump 121 may be used to Figure 3 The lubricating oil is output in the direction of the arrow shown, and the oil storage bottle 122 is used to store the lubricating oil. The oil replenishing pump 121 is, for example, a micro peristaltic pump, a piezoelectric ceramic micro pump, a micro electromagnetic valve pump, etc., which is not limited in the embodiment of the present application. Optionally, when the oil replenishing device 120 includes multiple oil outlets, the oil replenishing device 120 may also include multiple oil pipes ( Figure 3 It should be understood that the embodiment of the present application provides Figure 3This is only an example and does not represent the actual structure of the oil replenishing device 120 .

[0037] For example, in order to better understand the oil replenishment device 120 provided in the embodiment of the present application, which delivers lubricating oil to the target lubrication point through multiple oil outlets, please refer to Figure 4 , is a schematic diagram of an oil replenishing device provided in an embodiment of the present application replenishing oil to the track through multiple oil outlets. Figure 4 As shown, the oil replenishment device 120 is connected to multiple branch oil pipes, each corresponding to an oil outlet. Through different oil pipes, oil can be replenished to the target lubrication points at multiple oil outlets. In this case, the oil replenishment device 120 can be located above the center of the track or elsewhere. When the oil replenishment device 120 is located elsewhere, lubricating oil can be delivered from multiple oil outlets via the branch oil pipes. The layout of the branch oil pipes can be adaptively adjusted based on the location of the oil replenishment device 120, and this embodiment of the application is not limited to this.

[0038] When the oil replenishing device 120 has only one oil outlet, it can replenish oil at a fixed target lubrication point. Alternatively, the oil replenishing device 120 can be mounted on a target storage box, replenishing oil at different target lubrication points as the target storage box moves. The target storage box can be any one of a plurality of storage boxes. In this case, the track 130 can be provided with multiple target lubrication points, allowing the oil replenishing device 120 to replenish oil at target lubrication points at different locations.

[0039] The track 130 is provided below the support frame 110 and is used to guide each storage box to move along a preset moving path. Optionally, the track 130 may include multiple sub-tracks, and the division of the multiple sub-tracks may be set according to actual needs. For example, please refer to Figure 5 , is a schematic diagram of a sub-track division provided in an embodiment of the present application. Figure 5 As shown, the track 130 includes sub-tracks 131, 132, 133, 134, 135, 136, 137, 138 and 139. It should be understood that Figure 5 The sub-track division method shown is only an example provided in the embodiment of the present application. In actual applications, the specific sub-track division method can be set according to actual needs, and the embodiment of the present application does not limit this.

[0040] Please refer to Figure 6 , is a flow chart of a track maintenance method provided in an embodiment of the present application. The following is a flow chart of a track maintenance method performed by a track maintenance device. Figure 6 The track maintenance device is, for example, Figure 1 The controller in the smart bed frame shown ( Figure 1(not shown) or other electronic devices, which are not limited in the embodiments of the present application. Figure 6 The tracks involved are, for example, Figure 1 The track 130 shown, Figure 6 The oil replenishing device involved is, for example, Figure 6 The oil replenishing device 120 involved, Figure 6 The storage box involved is, for example, Figure 1 The storage box 140 is shown.

[0041] S601, obtaining movement data of multiple storage boxes.

[0042] The movement data of each storage box includes the start time of each movement, the movement duration, and the movement path. It should be understood that the movement path corresponds to the track path used when each storage box moves.

[0043] In a possible implementation, when a weight sensor is provided on the storage box, the movement data of each storage box further includes the weight during each movement.

[0044] For example, the track maintenance device can obtain the movement data of multiple storage boxes from a server. Alternatively, the track maintenance device can obtain the movement data of multiple storage boxes from a user device. The user device may be running an application for controlling the smart bed frame. Based on this, the track maintenance device can obtain the movement data of multiple storage boxes from the background records of the user device application. Alternatively, the track maintenance device may store the movement data of multiple storage boxes and thus directly obtain the movement data of multiple storage boxes.

[0045] For example, the track maintenance device may periodically re-lubricate the track. In this case, the track maintenance device may periodically acquire movement data for multiple storage boxes within a target time period. The target time period may be set based on actual needs, such as one day, one week, two weeks, one month, and so on, and is not limited in this embodiment of the present application. For example, if the track maintenance cycle is one month, the track maintenance device may acquire movement data for multiple storage boxes within one month prior to the current date.

[0046] Alternatively, after receiving the maintenance instruction, the track maintenance device may obtain movement data of multiple storage boxes between the last maintenance completion time and the current time. The maintenance instruction may be sent by a user via an application on a user device, or by a user device via a server, and this embodiment of the application is not limited thereto.

[0047] It should be noted that there is a usage association between multiple storage boxes. For example, when storage box A needs to be taken out, storage box B is also moved. In this case, storage box A and storage box B each generate a piece of movement data.

[0048] S602: Determine the friction degree of the track based on the movement data of the plurality of storage boxes.

[0049] The content of the movement data of the multiple storage boxes may correspond to the content described above and will not be repeated here.

[0050] Track friction refers to the resistance to movement between the track and the sliders and balls. Generally, the higher the track friction, the greater the resistance to movement between the track, sliders, and balls. The sliders and / or balls are the friction pair components in the track that, together with the track, guide the movement of the storage compartment.

[0051] The degree of track friction is related to various factors, such as the number of times the track is used and how often it is used. Based on this, embodiments of the present application provide various methods for determining the degree of track friction based on the movement data of multiple storage boxes. These various methods are described below.

[0052] Method 1: Determine the friction level of the track based on the number of times multiple storage boxes move during a target time period.

[0053] Specifically, the track maintenance device can calculate the number of times each storage box moves within the target time period based on the movement data of each storage box within the target time period. Based on the number of movements and the movement duration of the target time period, the movement frequency of each storage box within the target time period is calculated. For example, a calculation formula for calculating the movement frequency of each storage box within the target time period is as follows:

[0054] Movement frequency = number of moves ÷ time span

[0055] The time span is the time span between two consecutive moves. This time span is related to the unit of the move frequency. For example, if the unit of the move frequency is "times / day" and the target time period is one month, the corresponding time span is the number of days in a month, such as 30 days.

[0056] Since each storage box requires the use of the track each time it moves, the frequency of movement of the multiple storage boxes is equivalent to the frequency of track usage, which is related to the degree of track friction. Based on this, the track maintenance device can determine the degree of track friction based on the movement frequency of each storage box and the pre-stored first mapping relationship.

[0057] Specifically, the track maintenance device can calculate the sum of the movement frequencies of multiple storage boxes based on the movement frequency of each storage box. This sum of the movement frequencies of the multiple storage boxes is the track usage frequency. The track friction level can then be determined based on this sum of the movement frequencies of the multiple storage boxes and a first mapping relationship. The first mapping relationship includes a preset mapping relationship between movement frequency and friction level.

[0058] Illustratively, a first mapping relationship is shown in Table 1 below.

[0059] Table 1

[0060] Moving frequency (F) Degree of friction 0≤F＜5 Low 5≤F＜15 middle F≥15 high

[0061] As shown in Table 1, when the moving frequency is in the range of 0≤F<5, the friction level is low; when the moving frequency is in the range of 5≤F<15, the friction level is medium; and when the moving frequency is in the range of F≥15, the friction level is high.

[0062] In one possible implementation, the track maintenance device can also determine the track friction level based on the sum of the movement frequencies of the multiple storage compartments and a pre-trained friction estimation model. Specifically, the sum of the movement frequencies of the multiple storage compartments is input into the pre-trained friction estimation model to determine the track friction level. In this implementation, the track friction level can be quantified using the friction coefficient. Therefore, the output of the friction estimation model can also correspond to the track's current friction coefficient. The friction coefficient is used to quantify the track's sliding resistance and, therefore, can also reflect the track's friction level.

[0063] The pre-trained friction estimation model is trained based on a sample dataset, which includes sample movement frequency data. Optionally, to improve model estimation accuracy, the sample dataset may also include data such as track operating time, degradation coefficient, and initial friction coefficient. The degradation coefficient depends on the track material; for example, it is 0.0012 for steel rails and 0.0025 for plastic rails.

[0064] Frequent track use within a short period of time can increase track friction. For example, if the interval between two uses is less than 5 minutes, track friction will be more severe than if the interval between two uses is more than 30 minutes. This is because the shorter interval does not allow the track oil film to form quickly. Therefore, when calculating the movement frequency of each storage box, the movement frequency unit is set to "times / hour." This allows for a more accurate assessment of track friction and helps accurately determine the amount of oil replenishment required.

[0065] Alternatively, when the track maintenance device detects that the number of times each storage box has moved within a target duration is greater than or equal to the target number based on the movement data of each storage box, it is determined that the storage box has been moved frequently in a short period of time. Therefore, the movement frequency of each storage box within the target duration can be calculated based on the number of times each storage box has moved within the target duration, and the degree of friction of the track can be determined based on the movement frequency. The degree of friction of the track determined for the target time period is then updated based on the degree of friction of the track determined based on the movement frequency. For example, based on the method described above, if the degree of friction of the track within the target time period is determined to be medium, and the degree of friction of the track determined based on the movement frequency within the target duration is high, the degree of friction of the track is updated to high.

[0066] The target duration can be a period of time within the target time period, such as 30 minutes, 20 minutes, etc., and can be set according to actual needs. This embodiment of the present application does not limit this. The specific method of calculating the friction degree of the track based on the movement frequency can be referred to the content described above and will not be repeated here.

[0067] For example, taking the target duration as 20 minutes and the target number of times as 4 times, the track maintenance device detects that storage box A has moved 6 times between 15:30 and 15:50 minutes. It can be determined that the number of movements of storage box A within the target duration is greater than the target number of 6 times, that is, storage box A is moved frequently within the target duration. Therefore, the track maintenance device can calculate the movement frequency of storage box A within the target duration based on the number of movements of storage box A within the target duration, and then determine the degree of friction of the track based on the movement frequency.

[0068] Method 2: Determine the friction degree of the track according to the movement duration and movement path of each storage box during each movement within the target time period and the weight of each storage box during each movement.

[0069] Specifically, the track maintenance device can calculate the reference moving time of each storage box from the starting point to the end point of the moving path under the initial friction coefficient of the track based on the moving path of each storage box each time it moves, the weight of each time it moves, and the preset operating power of the driving device of each storage box. The initial friction coefficient may refer to the friction coefficient of the new track. Exemplarily, the track maintenance device can obtain the reference moving time of each storage box under the moving path based on the moving path of each storage box each time it moves, the weight of each time it moves, and the preset operating power of the driving device of each storage box through a pre-trained duration estimation model. The pre-trained duration estimation model can be trained based on sample moving paths and corresponding sample data such as weight and operating power.

[0070] In another possible embodiment, the reference moving duration of each moving path corresponding to each storage box may be pre-stored in the track maintenance device, and the reference moving duration of each moving path corresponding to each storage box may be obtained through experimental statistics or calculated by other means, which is not limited in this embodiment of the present application.

[0071] After obtaining the reference movement duration corresponding to each storage box's movement path, the number of abnormal movements of each storage box within the target time period can be determined based on the movement duration of each movement in the movement data of each storage box and the corresponding reference movement duration. Specifically, the track maintenance device can compare the movement duration of each movement in the movement data of each storage box with the corresponding reference movement duration. If the movement duration of each movement is greater than the corresponding reference movement duration, the current movement is determined to be abnormal, and the number of abnormal movements is increased by one. Based on the same method, the number of abnormal movements of each storage box within the target time period can be determined.

[0072] In one possible embodiment, since the storage box may be affected by the environment during movement, there may be a small difference between the actual movement duration and the reference movement duration. Therefore, in order to more accurately determine the number of abnormal movements of each storage box, the track maintenance device may compare the movement duration of each movement in the movement data of each storage box with the corresponding reference movement duration. When the movement duration of each movement is greater than the corresponding reference movement duration, the difference between the movement duration of each movement and the corresponding reference movement duration is calculated. If the difference is greater than a preset first threshold, it is determined that the current movement is an abnormal movement. The first threshold may be pre-configured in the track maintenance device, and the first threshold may be set through experience or experimental statistics, which is not limited in this embodiment of the present application.

[0073] After determining the number of abnormal movements of each storage box within a target time period, the track maintenance device can calculate the total number of abnormal movements for the multiple storage boxes within the target time period. Based on the total number of abnormal movements for the multiple storage boxes within the target time period, the degree of track friction can be determined. Specifically, the track maintenance device can determine the degree of track friction based on the total number of abnormal movements and a preset second mapping relationship. The second mapping relationship includes a preset mapping relationship between the total number of abnormal movements and the degree of friction.

[0074] Illustratively, a second mapping relationship may be shown in Table 2 below.

[0075] Table 2

[0076] Total number of abnormalities (M) Degree of friction 0≤M＜3 Low 3≤M＜5 middle M≥5 high

[0077] Among them, when the total number of abnormalities is in the range of 0≤M<3, the friction degree of the track is low; when the total number of abnormalities is in the range of 3≤M<5, the friction degree of the track is medium; when the total number of abnormalities is in the range of M≥5, the friction degree of the track is high.

[0078] In one possible implementation, the degree of track friction can be quantified using a friction coefficient. In this case, the track maintenance device can calculate the track friction coefficient based on the total number of anomalies and a preset first quantification coefficient. For example, the track maintenance device can use the product of the total number of anomalies and the first quantification coefficient as the track friction coefficient. The first quantification coefficient can be preconfigured in the track maintenance device. The quantification coefficient can be obtained through experimental analysis of the relationship between the friction coefficient and the total number of anomalies, or can be determined through empirical setting.

[0079] Method three: determine the friction degree of the track according to the moving path of each storage box.

[0080] Because each storage box moves along a different path, it uses a different track segment. Each box also moves at a different frequency, which can result in some sections of the track being used more frequently and others less frequently. Therefore, the entire track can be divided into multiple sub-tracks. The frequency of use of each sub-track, and thus the degree of track friction, can be determined by the movement paths of multiple storage boxes.

[0081] Specifically, the track maintenance device can calculate the usage frequency of each sub-track corresponding to each storage box based on the movement path of each storage box during the target time period. For example, based on the movement path of each storage box, the sub-track used by each storage box during each movement can be determined. Furthermore, by counting the sub-tracks corresponding to all movement paths of each storage box during the target time period, the usage frequency of each sub-track can be obtained.

[0082] For example, the movement paths of storage box A during the target time period include movement paths 1, 2, and 3. The track maintenance device determines that the subtracks corresponding to movement path 1 include subtrack a, subtrack b, and subtrack c; the subtracks corresponding to movement path 2 include subtrack a, subtrack b, and subtrack c; and the subtracks corresponding to movement path 3 include subtrack b, subtrack d, and subtrack f. Based on this, the track maintenance device can determine that subtrack a was used twice, subtrack b was used three times, subtrack c was used twice, and subtrack d and subtrack f were used once during the target time period.

[0083] After calculating the number of times each sub-track corresponding to each storage box is used, the total number of times each sub-track corresponding to multiple storage boxes is counted. Based on a preset time span and the total number of times each sub-track is used, the frequency of use of each sub-track can be calculated. The time span is described in detail above and will not be repeated here. The degree of friction of each sub-track can then be determined based on the frequency of use of each sub-track. Specifically, the track maintenance device can determine the degree of friction of each sub-track based on the frequency of use of each sub-track and a preset third mapping relationship. The third mapping relationship includes a preset mapping relationship between frequency of use and degree of friction.

[0084] Illustratively, a third mapping relationship may be shown in Table 3 below.

[0085] Table 3

[0086] Frequency of use (F) Degree of friction 0≤F＜4 Low 4≤F＜8 middle F≥8 high

[0087] As shown in Table 3 above, when the usage frequency of each sub-track is in the range of 0≤F<4, the friction level of each sub-track is low; when the usage frequency of each sub-track is in the range of 4≤F<8, the friction level of each sub-track is medium; when the usage frequency of each sub-track is in the range of F≥8, the friction level of each sub-track is high.

[0088] In one possible embodiment, the degree of track friction can be quantified using a friction coefficient. In this case, the track maintenance device can also calculate the friction coefficient of each sub-track based on the frequency of use of each sub-track and a preset calculation formula, thereby determining the degree of friction for each sub-track. Because the relationship between track usage frequency and the friction coefficient is nonlinear and increasing, this nonlinear increasing relationship can be statistically analyzed using experimental data, and a calculation formula constructed based on this nonlinear increasing relationship can be constructed.

[0089] Furthermore, after obtaining the friction degree of each sub-track, the friction degree of the track can be determined based on the friction degree of each sub-track. Specifically, the track maintenance device can determine the highest friction degree among the friction degrees of the multiple sub-tracks as the friction degree of the track.

[0090] Alternatively, when quantifying the degree of track friction using a friction coefficient, the track friction device may perform a weighted average of the friction coefficients of multiple sub-tracks to obtain an average friction coefficient of the track, which represents the degree of track friction. Alternatively, the maximum friction coefficient among the multiple sub-tracks may be used to represent the degree of track friction.

[0091] The above are several ways to determine the degree of friction of the track provided in the embodiments of the present application. Of course, based on the movement data of each storage box, other ways to determine the degree of friction of the track may also be included. The embodiments of the present application will not be given one by one here.

[0092] S603, determining operating parameters of the oil replenishing device according to the degree of friction of the track. The operating parameters are used to control the oil output of the oil replenishing device. The oil output is positively correlated with the degree of friction of the track.

[0093] The operating parameters of the refueling device may include its pulse parameters. Pulse parameters are core parameters for controlling the refueling device's operating status. Pulse parameters may include pulse width, pulse frequency, and pulse waveform characteristics. Pulse width controls the amount of oil delivered per pulse of the refueling device, while pulse frequency controls the number of pulses executed per second. Pulse waveform characteristics refer to the duration of the pulse rise and fall, controlling the response time of a single refueling operation.

[0094] Optionally, the operating parameters of the oil replenishing device may also include other environmental parameters, such as temperature, humidity, etc., which are not limited in the embodiment of the present application.

[0095] Generally speaking, the more severe the friction of the track, the more oil replenishment the track requires, and the more oil output the oil replenishment device needs to output. Based on this, the track maintenance device can determine the total oil replenishment required for the track according to the friction level of the track, and then calculate the target pulse width and target pulse frequency of the oil replenishment device based on the total oil replenishment amount and the preset oil replenishment amount per unit time. Among them, the oil replenishment amount per unit time is the upper limit of the amount of lubricating oil output by the preset oil replenishment device per unit time. In the scenario of the smart bed frame, if the amount of oil output by the oil replenishment device per unit time is large, it will cause the lubricating oil to accumulate at the same lubrication point, causing the lubrication point to block the track or drip. Therefore, in the embodiment of the present application, the oil replenishment amount of the oil replenishment device per unit time is set to avoid this situation.

[0096] Specifically, the track maintenance device can determine the total amount of oil replenishment required for the track based on the level of track friction and a preset fourth mapping relationship. The fourth mapping relationship includes a mapping relationship between the preset level of friction and the total amount of oil replenishment. For example, one such fourth mapping relationship is shown in Table 4 below.

[0097] Table 4

[0098] Degree of friction Total oil replenishment volume (ml) Low 0.005ml middle 0.020ml high 0.035ml

[0099] As shown in Table 4, when the friction level is low, the total oil replenishment amount is 0.005 ml; when the friction level is medium, the total oil replenishment amount is 0.020 ml; and when the friction level is high, the total oil replenishment amount is 0.035 ml.

[0100] In a possible implementation, the friction degree of the track is quantified by a friction coefficient. Therefore, another fourth mapping relationship may be shown in Table 5 below.

[0101] Table 5

[0102] Degree of friction (friction coefficient μ) Total oil replenishment volume (ml) μ≤0.04 0.005ml 0.04<μ≤0.06 0.010ml 0.06<μ≤0.08 0.025ml 0.08<μ 0.045ml

[0103] As shown in Table 5 above, when the friction coefficient is in the range of μ≤0.04, the total oil replenishment amount is 0.005 ml; when the friction coefficient is in the range of 0.04<μ≤0.06, the total oil replenishment amount is 0.010 ml; when the friction coefficient is in the range of 0.06<μ≤0.08, the total oil replenishment amount is 0.025 ml; when the friction coefficient is in the range of 0.08<μ, the total oil replenishment amount is 0.045 ml.

[0104] In another possible implementation, the track maintenance device can further calculate the oil replenishment amount for each sub-track based on the corresponding friction level of each sub-track. The total oil replenishment amount for the track can be calculated by summing the oil replenishment amounts for multiple sub-tracks. In this implementation, the track maintenance device can determine the oil replenishment amount for each sub-track based on a preset mapping relationship between friction level and oil replenishment amount. The mapping relationship between friction level and oil replenishment amount can be referred to the example shown in Table 4 above and will not be further described here.

[0105] The amount of oil replenished for each sub-track is also related to the length of each sub-track. Specifically, the amount of oil replenished for each sub-track is positively correlated with the sub-track, that is, under the same degree of friction, the longer the length of each sub-track, the greater the amount of oil replenished. Based on this, the track maintenance device can also calculate the amount of oil replenished for each sub-track according to the degree of friction corresponding to each sub-track, the length corresponding to each sub-track, and a preset proportional coefficient. Exemplarily, the track maintenance device can determine the corresponding initial amount of oil replenished according to the degree of friction corresponding to each sub-track, and then calculate the amount of oil replenished for each sub-track according to the product of the preset amount of oil replenished, the length corresponding to each sub-track, and the preset proportional coefficient. Among them, the initial amount of oil replenished can be the amount of oil replenished required under the reference length of the sub-track, and the preset proportional coefficient can be obtained by analyzing the proportional relationship between the track length and the amount of oil replenished.

[0106] After determining the total refueling volume for the track, the operating parameters of the refueling device can be determined. Specifically, the track maintenance device can determine a refueling strategy corresponding to the total refueling volume and the preset refueling volume per unit time. This refueling strategy includes the target pulse width and target pulse frequency of the refueling device. In other words, different pulse widths and pulse frequencies are set for different total refueling volumes to obtain refueling strategies corresponding to different total refueling volumes. It should be noted that, in this manner, the refueling volume per second corresponding to the operating parameters in each refueling strategy will not exceed the preset refueling volume per unit time.

[0107] In one possible implementation, the track maintenance device can also calculate the target pulse width and target pulse frequency of the refueling device based on the total refueling amount and the preset refueling amount per unit time using a pre-trained parameter determination model. Specifically, the total refueling amount and the preset refueling amount per unit time are input into the pre-trained parameter determination model to obtain the target pulse width and target pulse frequency. The pre-trained parameter determination model can be trained based on sample refueling amounts, preset refueling amounts per unit time, and corresponding sample operating parameters.

[0108] In one possible embodiment, when the track maintenance device determines the degree of friction of each sub-track, the oil replenishment device may include multiple oil outlets, each oil outlet corresponding to at least one of the multiple sub-tracks. In this case, the track maintenance device can determine the total oil replenishment amount for the track based on the degree of friction of the track, and then determine the oil output amount that each oil outlet should output based on the degree of friction of each sub-track and the total oil replenishment amount. Then, based on the total oil replenishment amount and the oil output amount that each oil outlet should output, the operating parameters of the oil replenishment device are determined. The specific method for the track maintenance device to determine the total oil replenishment amount for the track based on the degree of friction of the track can be referred to the content described above and will not be repeated here.

[0109] After determining the total oil replenishment amount of the track, the amount of lubricating oil (oil output) that each oil outlet should output can be determined based on the friction level of the sub-track corresponding to each oil outlet and the total oil replenishment amount. Specifically, the track maintenance device can determine the corresponding target weight coefficient based on the friction level of the sub-track corresponding to each oil outlet, and then calculate the oil output that each oil outlet should output based on the target weight coefficient and the total oil replenishment amount. For example, the track maintenance device can determine the oil output that each oil outlet should output by multiplying the target weight coefficient corresponding to each oil outlet by the total oil replenishment amount. Among them, the target weight coefficient is pre-configured in the track maintenance device, and different friction levels correspond to different weight coefficients. The friction level and the weight coefficient are positively correlated, that is, the higher the friction level, the higher the corresponding weight coefficient. Since an oil outlet may correspond to at least one sub-track, the friction level of the sub-track corresponding to each oil outlet can be the sum of the friction levels of at least one sub-track. Among them, the calculation method of the sum of the friction levels of at least one sub-track can refer to the content described above and will not be repeated here.

[0110] In one possible embodiment, if the oil replenishment device has multiple oil outlets, the track maintenance device can further determine the operating parameters of the oil replenishment device based on the friction level of the sub-track corresponding to each oil outlet and the total oil replenishment volume using a pre-trained parameter determination model. This allows the oil replenishment device to be controlled based on these operating parameters to deliver lubricating oil to the multiple oil outlets, ensuring that the oil output from each outlet matches the friction level of the corresponding sub-track. The training method for the pre-trained parameter determination model can be referenced above and will not be further elaborated here.

[0111] S604: Control the oil replenishing device to output lubricating oil to a target lubrication point in the track through at least one oil outlet according to the operating parameters.

[0112] The operating parameters described in step S604 are the target pulse width and target pulse frequency determined by the track maintenance device.

[0113] In one embodiment, the oil replenishment device is fixed to the support frame and thus outputs lubricating oil from a fixed main oil outlet. The oil is then delivered to multiple oil outlets via branch oil pipes. In this case, each oil outlet in the oil replenishment device corresponds to a target lubrication point. Specifically, the track maintenance device controls the oil replenishment device to deliver lubricating oil to the target lubrication points in the track through the multiple oil outlets based on the target pulse width and target pulse frequency.

[0114] In one possible embodiment, in this case, to prevent excessive oil flow from the oil outlet, which could lead to lubricating oil accumulation or dripping, a flow valve can be installed at each oil outlet to control the oil flow from each outlet, ensuring that the oil flow from each outlet meets the required output. In particular, when some of the multiple sub-tracks do not require oil replenishment, the flow valve can control the oil flow from the corresponding outlet to zero.

[0115] In another embodiment, the oil replenishment device may be mounted on a target storage box, which may be equipped with a drive mechanism configured to drive each storage box along a preset movement path. The target storage box may be any of a plurality of storage boxes. The preset movement path refers to the path along which the target storage box moves to the target lubrication point. In this case, the track maintenance device may determine the target lubrication point on the track based on the friction level of the track and then control the target storage box to move toward the target lubrication point. Upon receiving a message indicating that the target storage box has reached the target lubrication point, the device may control the oil replenishment pump in the oil replenishment module to operate according to the target pulse width and target pulse frequency to replenish the target lubrication point. For example, a communication module may be mounted on the target storage box. When the target storage box reaches the position corresponding to the target lubrication point, the communication module may transmit a message indicating that the target storage box has reached the target lubrication point. The communication module is described above and will not be further elaborated here.

[0116] Exemplarily, the track maintenance device can determine the target lubrication point of each sub-track based on the degree of friction of each sub-track. For example, if the degree of friction of each sub-track is low, the center position of the sub-track is determined as a target lubrication point. If the degree of friction of each sub-track is high, the two end points and the center position of the sub-track are determined as three target lubrication points. In this case, after determining the target lubrication points, the track maintenance device can determine the corresponding oil replenishment amount for each target lubrication point based on the total oil output and the total number of target lubrication points. Specifically, the total oil output can be evenly distributed among all target lubrication points. Accordingly, in this case, the track maintenance device can control the oil replenishment pump in the oil replenishment module to work according to the target pulse width and target pulse frequency based on the target pulse width and target pulse frequency, so as to output the corresponding oil replenishment amount to the target lubrication point.

[0117] In one possible implementation, since the tracks are prone to dust accumulation and foreign objects, brushes may be installed at the connection between the drive device and the track to improve track oil replenishment. Before the track maintenance device controls the oil replenishment device to replenish oil, the track maintenance device can control each storage box to move according to a target movement strategy, so that the track is cleaned by the brushes installed on multiple storage boxes. The target movement strategy refers to the movement strategy required to completely clean the entire track.

[0118] In one possible implementation, after the oil replenishment device has finished replenishing lubricating points, the track maintenance device can also control the movement of multiple storage boxes according to a targeted movement strategy to ensure that lubrication points are fully covered across the entire track. This ensures that the entire track is effectively maintained, thereby increasing the track's service life.

[0119] By implementing the technical solutions described in the embodiments of the present application, not only is automated track maintenance achieved, but the total oil replenishment amount of the oil replenishing device can also be accurately controlled based on the degree of friction of the track, effectively avoiding the problem of lubricating oil blocking the track and affecting the movement of the storage box due to excessive oil replenishment, and effectively avoiding the problem of excessive lubricating oil dripping into the storage box, resulting in a poor user experience, and also effectively avoiding the problem of failing to achieve the purpose of track life maintenance due to insufficient oil replenishment.
