[0033] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure.

[0034] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] In the related art, manual auxiliary lubrication and maintenance of chain equipment on a regular basis has the following defects: first, the cost of manual auxiliary lubrication and maintenance of the equipment is high; second, it is difficult to timely perform auxiliary lubrication and maintenance on the equipment when the equipment is short of oil; third, the auxiliary lubrication of the chain equipment is performed based on human experience. If too little oil is added each time and the lubrication is not in place, the chain equipment will often get stuck or even break, reducing the transportation efficiency; if too much oil is added each time, it will lead to waste of lubricating oil.

[0040] In view of this, the present disclosure proposes an equipment lubrication control method, device and system, which can automatically and intelligently refuel the equipment, reduce the cost of auxiliary lubrication and maintenance of the equipment, timely perform auxiliary lubrication and maintenance on oil-deficient equipment, and improve equipment transportation efficiency.

[0041] Figure 1 Schematic diagram showing the structure of a chain conveyor according to some embodiments of the present disclosure. Figure 1 As shown, the chain conveyor includes: chain conveyor belts 11, 12, collection modules 31, 32, a lubrication control device 41 of the equipment, and a motor 42.

[0042] The chain conveyor is mainly used for conveying articles such as cigarette boxes 21. It is driven by a motor 42 and drives the chain conveyor belt through gears for cyclic conveying.

[0043] The acquisition modules 31 and 32 are used to monitor the load flow of the chain conveyor and the operating torque of the motor. In some embodiments, the acquisition modules include a positioning photoelectric tube and a motor torque measuring device, wherein the positioning photoelectric tube is used to measure the load flow of the chain conveyor.

[0044] The lubrication control device 41 of the equipment is arranged below the chain conveyor belt 12 and is used to control the refueling device to refuel the equipment according to the load flow monitored by the acquisition module 31 and the operating torque of the motor.

[0045] The refueling device includes an oil pump (not shown) and an oil delivery pipe 42. In some embodiments, the oil pump is used to start and stop refueling according to instructions from the equipment lubrication control device 41. One end of the oil delivery pipe 42 is connected to the oil pump, and the other end is connected to the part of the chain conveyor that requires lubrication and refueling.

[0046] In the disclosed embodiment, by setting a lubrication control device 41 of the equipment on the chain conveyor, the equipment can be automatically and intelligently refueled, reducing the cost of auxiliary lubrication and maintenance of the equipment, and timely performing auxiliary lubrication and maintenance on the oil-deficient equipment, thereby improving the equipment transportation efficiency.

[0047] Figure 2 FIG. 1 is a flow chart illustrating a lubrication control method for an apparatus according to some embodiments of the present disclosure. Figure 2 As shown, the lubrication control method of the equipment in the embodiment of the present disclosure includes:

[0048] Step S210: Acquire a first operating torque measurement value sequence of the device and a load flow corresponding to each operating torque measurement value in the first operating torque measurement value sequence.

[0049] In some embodiments, the operating torque of a device (e.g., a chain conveyor) and the load flow of the device are monitored in real time within a set time period to obtain a first operating torque measurement value sequence of the device and the load flow corresponding to each operating torque measurement value in the first operating torque measurement value sequence.

[0050] Load flow generally refers to the number of items transported by a device per unit time. For example, the number of cigarette boxes transported per unit time on a chain conveyor.

[0051] Step S220: determining the theoretical operating torque corresponding to each operating torque measurement value according to the load flow corresponding to each operating torque measurement value.

[0052] In step S220 , the theoretical operating torque corresponding to each operating torque measurement value is determined according to the load flow corresponding to each operating torque measurement value and a preset correspondence relationship between the load flow and the theoretical operating torque.

[0053] For example, a correspondence table between different load flows and theoretical operating torques is pre-set. After obtaining the load flow corresponding to each operating torque measurement value in the first operating torque measurement value sequence through step S210, the theoretical operating torque corresponding to each operating torque measurement value in the first operating torque measurement value sequence is determined by querying the correspondence table.

[0054] Step S230: determining a torque deviation accumulation value according to each operating torque measurement value and its corresponding theoretical operating torque.

[0055] In some embodiments, step S230 includes: for each operating torque measurement value in the first operating torque measurement value sequence, calculating the first deviation between each operating torque measurement value and its corresponding theoretical operating torque, and accumulating the calculated first deviations to obtain a torque deviation accumulated value.

[0056] For example, the first operating torque measurement value sequence is {T1, T2, T3, T4, T5}, and the theoretical operating torque corresponding to each operating torque measurement value in the sequence is T1_T5. 理 、T2_ 理 、T3_ 理 、T4_ 理 、T5_ 理 , the following 5 first deviations are calculated: T1-T1_ 理 、T2-T2_ 理 、T3-T3_ 理 、T4-T4_ 理 , and T5-T5_ 理 , accumulate these five first deviations to obtain the torque deviation accumulation value.

[0057] In some embodiments, step S230 includes: calculating the first deviation between each operating torque measurement value in the first operating torque measurement value sequence and its corresponding theoretical operating torque; screening out the first deviation that is greater than the allowable torque deviation from the first deviation between each operating torque measurement value and its corresponding theoretical operating torque; and accumulating the screened out first deviations that are greater than the allowable torque deviation to obtain a torque deviation accumulated value.

[0058] For example, the first operating torque measurement value sequence is {T1, T2, T3, T4, T5}, and the theoretical operating torque corresponding to each operating torque measurement value in the sequence is T1_T5. 理 、T2_ 理 、T3_ 理 、T4_ 理 、T5_ 理 , the following 5 first deviations are calculated: T1-T1_ 理 、T2-T2_ 理 、T3-T3_ 理 、T4-T4_ 理 , and T5-T5_ 理 By comparing these five first deviations with the corresponding allowable torque deviations, we can obtain: T1-T1_ 理 、T2-T2_ 理 and T3-T3_ 理 Greater than the corresponding allowable torque deviation, T4-T4_ 理 and T5-T5_ 理 is smaller than the corresponding allowable torque deviation. 理 、T2-T2_ 理 and T3-T3_ 理 The three first deviations are accumulated to obtain a torque deviation accumulation value.

[0059] In some embodiments, the allowable torque deviation is determined as follows: collecting device operating torque sample data corresponding to each load flow under multiple load flows; determining the allowable torque deviation corresponding to each load flow based on the maximum value and average value of the device operating torque sample data corresponding to each load flow.

[0060] In some embodiments, the allowable torque deviation corresponding to each load flow is positively correlated with the maximum value of the equipment operating torque sample data corresponding to each load flow, and negatively correlated with the average value of the equipment operating torque sample data corresponding to each load flow.

[0061] For example, the allowable torque deviation corresponding to each load flow is determined according to the following formula:

[0062]

[0063] Where, ΔT i Indicates the allowable torque deviation corresponding to the i-th load flow, T imax It represents the maximum torque value in the equipment operating torque sample data corresponding to the i-th load flow. represents the average torque of the equipment operating torque sample data corresponding to the i-th load flow, α is the equipment wear coefficient, and the smaller its value is, the less equipment wear is. In some embodiments, the value range of α is 1.2 to 1.5.

[0064] Step S240: When the accumulated torque deviation value satisfies a first preset condition, controlling the refueling device to refuel the equipment.

[0065] In some embodiments, the first preset condition includes: the torque deviation accumulated value is greater than or equal to a deviation threshold.

[0066] In some embodiments, the lubrication control method of the equipment further includes: if the torque deviation accumulated value does not meet the first preset condition, executing steps S210 to S230 again, and determining again whether the torque deviation accumulated value meets the first preset condition.

[0067] In the disclosed embodiment, the above steps can automatically and intelligently refuel the equipment based on the monitoring of the equipment's operating torque and load flow data, thereby reducing the cost of auxiliary lubrication and maintenance of the equipment, and timely performing auxiliary lubrication and maintenance on oil-deficient equipment, thereby improving equipment transportation efficiency.

[0068] Figure 3 FIG. 1 is a flow chart showing a lubrication control method for a device according to other embodiments of the present disclosure. Figure 3 As shown, the lubrication control method of the equipment in the embodiment of the present disclosure includes:

[0069] Step S310: collecting operating torque data and load flow data.

[0070] In some embodiments, the operating torque of a device (e.g., a chain conveyor) is measured in real time based on a torque measuring device within a set time period, and the load flow of the device within the set time period is measured based on a positioning photoelectric sensor to obtain operating torque data and load flow data.

[0071] Step S320: pre-process the data.

[0072] In some embodiments, step S320 includes downsampling the collected operating torque data and load flow data, for example, by taking an average of the operating torque data within a preset time interval.

[0073] For example, assuming that a total of 1000 operating torque measurement values are collected in a set time period t1, 100 pre-processed operating torque measurement values are obtained by averaging 10 operating torque measurement values collected within a preset time interval t1 / 100.

[0074] In some embodiments, step S320 includes: aligning the collected operating torque data and load flow data.

[0075] For example, when the collection frequency of the operating torque data is different from the collection frequency of the load flow data, the operating torque data and the load flow data are aligned according to the collection timestamps.

[0076] Step S330: determining a torque deviation accumulation value and a deviation threshold value according to the pre-processed operating torque data and load flow data.

[0077] The pre-processed operating torque data and load flow data are a first operating torque measurement value sequence and a load flow corresponding to each operating torque measurement value in the first operating torque measurement value sequence.

[0078] In some embodiments, the torque deviation cumulative value is determined as follows: based on the load flow corresponding to each operating torque measurement value in the first operating torque measurement value sequence, and the correspondence between the load flow and the theoretical operating torque, the theoretical operating torque corresponding to each operating torque measurement value is determined; the first deviation between each operating torque measurement value and its corresponding theoretical operating torque is calculated; from the first deviation between each operating torque measurement value and its corresponding theoretical operating torque, the first deviation that is greater than the allowable torque deviation is screened out; and the screened out first deviations that are greater than the allowable torque deviation are accumulated to obtain the torque deviation cumulative value.

[0079] In the embodiment of the present disclosure, by retaining only the first deviation that is greater than the allowable torque deviation and determining the torque deviation cumulative value based on the retained first deviation that is greater than the allowable torque deviation, it is possible to better judge whether auxiliary refueling of the equipment is required, thereby improving the accuracy of equipment lubrication control.

[0080] In some embodiments, the deviation threshold is determined as follows: an operating torque measurement value is screened out from a first operating torque measurement value sequence, and the operating torque measurement value whose first deviation from the theoretical operating torque is greater than the allowable torque deviation is screened out; the allowable torque deviation corresponding to the screened operating torque measurement value is determined; and the deviation threshold is determined based on the allowable torque deviation corresponding to the screened operating torque measurement value.

[0081] In some embodiments, after obtaining the allowable torque deviation corresponding to the filtered operating torque measurement value, the deviation threshold is determined according to the following method: accumulating the allowable torque deviation corresponding to the filtered operating torque measurement value to obtain an accumulated result; and determining the deviation threshold based on the accumulated result.

[0082] For example, the deviation threshold is calculated according to the following formula:

[0083]

[0084] Where, ΔT m is the deviation threshold, m is the number of operating torque measurement values selected from the first operating torque measurement value sequence, whose first deviation from the theoretical operating torque is greater than the allowable torque deviation, ΔT j Indicates the allowable torque deviation corresponding to the j-th filtered operating torque measurement value.

[0085] In the embodiment of the present disclosure, by determining the deviation threshold in the above manner, the corresponding deviation threshold can be dynamically determined for different operating torque and load flow monitoring data, thereby helping to more accurately judge whether auxiliary refueling of the equipment is required, thereby improving the accuracy of equipment lubrication control.

[0086] Step S340: Determine whether the torque deviation accumulated value is greater than or equal to the deviation threshold.

[0087] If the judgment result of step S340 is yes, step S350 is executed; otherwise, steps S310 to S340 are executed again.

[0088] Step S350: Control the refueling device to refuel the equipment.

[0089] In some embodiments, according to Figure 4 The process shown controls the refueling device to refuel the equipment.

[0090] In other embodiments, the amount of oil to be refueled is determined based on a comparison result between the torque deviation cumulative value and the deviation threshold; and the refueling device is instructed to refuel the equipment according to the amount of oil to be refueled.

[0091] In the disclosed embodiment, the above device can automatically and intelligently refuel the equipment based on the monitoring of the equipment's operating torque and load flow data, thereby reducing the cost of auxiliary lubrication and maintenance of the equipment, and timely providing auxiliary lubrication and maintenance for oil-deficient equipment, thereby improving equipment transportation efficiency.

[0092] Figure 4 It is a schematic diagram showing a process of controlling a refueling device to refuel equipment according to some embodiments of the present disclosure. Figure 4 The process shown is Figure 3 The following is an exemplary description of step S350. Figure 4 As shown, the process of controlling the refueling device to refuel the equipment includes:

[0093] Step S351: Instruct the refueling device to start refueling the equipment.

[0094] In some embodiments, a control instruction to start refueling is sent to the refueling device to instruct the refueling device to start refueling the equipment. The control instruction to start refueling carries an automatic lubrication flag, and the value of the automatic lubrication flag is a first value.

[0095] Step S352: Evaluate the lubrication effect of the equipment during the refueling process.

[0096] Step S353: When the lubrication effect evaluation value of the equipment meets the second preset condition, instruct the refueling device to stop refueling the equipment.

[0097] In some embodiments, the second preset condition includes: a lubrication effect evaluation value of the equipment is greater than or equal to a lubrication effect evaluation threshold.

[0098] In some embodiments, when the lubrication effect evaluation value of the equipment meets the second preset condition, a stop refueling control instruction is sent to the refueling device to instruct the refueling device to stop refueling the equipment. The stop refueling control instruction carries an automatic lubrication flag, and the value of the automatic lubrication flag is the second value.

[0099] In the embodiment of the present disclosure, by evaluating the lubrication effect of the equipment during the refueling process and determining the refueling amount based on the lubrication effect evaluation results, the amount of oil to be refueled can be determined more accurately and the effect of auxiliary lubrication of the equipment can be optimized.

[0100] Figure 5 It is a schematic diagram showing a process of controlling a refueling device to refuel equipment according to other embodiments of the present disclosure. Figure 5 The process shown is similar to Figure 4 The main difference between the process shown is that it further provides an exemplary process of step S352. Figure 5 As shown, the exemplary process of step S352 includes:

[0101] Step S3521: Acquire a second operating torque measurement value sequence of the equipment during the refueling process, and a load flow rate corresponding to each operating torque measurement value in the second operating torque measurement value sequence.

[0102] In some embodiments, the operating torque of the equipment (e.g., a chain conveyor) and the load flow of the equipment during the refueling process are monitored in real time within a set time period to obtain a second operating torque measurement value sequence of the equipment and the load flow corresponding to each operating torque measurement value in the second operating torque measurement value sequence.

[0103] Step S3522: Determine the theoretical operating torque corresponding to each operating torque measurement value according to the load flow corresponding to each operating torque measurement value.

[0104] In this step, the theoretical operating torque corresponding to each operating torque measurement value is determined according to the load flow corresponding to each operating torque measurement value in the second operating torque measurement value sequence and the preset correspondence between the load flow and the theoretical operating torque.

[0105] For example, a correspondence table between different load flows and theoretical operating torques is pre-set. After obtaining the load flow corresponding to each operating torque measurement value in the second operating torque measurement value sequence through step S3521, the theoretical operating torque corresponding to each operating torque measurement value in the second operating torque measurement value sequence is determined by querying the correspondence table.

[0106] Step S3523: Determine a lubrication effect evaluation value based on each operating torque measurement value and its corresponding theoretical operating torque.

[0107] In some embodiments, the lubrication effect evaluation value is determined as follows: the second deviation between each operating torque measurement value in the second operating torque measurement value sequence and its corresponding theoretical operating torque is calculated; from the second deviation between the theoretical operating torque and each operating torque measurement value, the second deviation that is smaller than the allowable torque deviation is screened out; the screened second deviations that are smaller than the allowable torque deviation are accumulated to obtain the lubrication effect evaluation value.

[0108] For example, the second operating torque measurement value sequence is {T6, T7, T8, T9, T10}, and the theoretical operating torque corresponding to each operating torque measurement value in the sequence is T6_T10. 理 、T7_ 理 、T8_ 理 、T9_理 、T10_ 理 , the following 5 second deviations are calculated: T6_ 理 -T6, T7_ 理 -T7, T8_ 理 -T8, T9_ 理 -T9, and T10_ 理 -T10. By comparing these 5 second deviations with the corresponding allowable torque deviations, we can obtain: T6_ 理 -T6, T7_ 理 -T7, T8_ 理 -T8 is less than the corresponding permissible torque deviation, T9_ 理 -T9, and T10_ 理 -T10 is greater than the corresponding allowable torque deviation. Then, the three second deviations are accumulated to obtain the lubrication effect evaluation value.

[0109] Step S3524: Determine whether the lubrication effect evaluation value is greater than or equal to the lubrication effect evaluation threshold.

[0110] In some embodiments, the lubrication effect evaluation threshold is determined as follows: an operating torque measurement value is screened out from the second operating torque measurement value sequence, and the second deviation between the operating torque and the theoretical operating torque is less than the allowable torque deviation; the allowable torque deviation corresponding to the screened operating torque measurement value is determined; and the lubrication effect evaluation threshold is determined based on the allowable torque deviation corresponding to the screened operating torque measurement value.

[0111] In some embodiments, after obtaining the allowable torque deviation corresponding to the filtered operating torque measurement value, the lubrication effect evaluation threshold is determined according to the following method: the allowable torque deviation corresponding to the filtered operating torque measurement value is accumulated to obtain an accumulated result; and the lubrication effect evaluation threshold is determined based on the accumulated result.

[0112] For example, the lubrication effect evaluation threshold is calculated according to the following formula:

[0113]

[0114] Where, ΔT K is the lubrication effect evaluation threshold, K is the number of operating torque measurement values selected from the second operating torque measurement value sequence, whose second deviation from the theoretical operating torque is less than the allowable torque deviation, ΔT k Indicates the allowable torque deviation corresponding to the k-th filtered operating torque measurement value.

[0115] In the embodiment of the present disclosure, the lubrication effect evaluation threshold is determined in the above manner, and the corresponding lubrication effect evaluation threshold can be dynamically determined based on different operating torque and load flow monitoring data during the refueling process, thereby helping to more accurately determine how much oil needs to be added to the equipment and improve the accuracy of equipment lubrication control.

[0116] If the judgment result of step S3524 is yes, execute step S353; otherwise, execute steps S3521 to S3524 again.

[0117] In the embodiment of the present disclosure, the above steps can more accurately evaluate the lubrication effect of the equipment during the refueling process, thereby more accurately determining the amount of oil to be refueled and optimizing the effect of auxiliary lubrication of the equipment.

[0118] Figure 6 1 is a partial flow chart showing a lubrication control method for a device according to some embodiments of the present disclosure. In some embodiments, the lubrication control method for a device according to an embodiment of the present disclosure is executed by a lubrication control device of the device. Figure 6 As shown, the lubrication control method of the equipment in the embodiment of the present disclosure includes:

[0119] Step S601: monitoring a first operating torque measurement value sequence of a device and a load flow rate corresponding to each operating torque measurement value in the sequence.

[0120] Step S602: Determine the theoretical operating torque corresponding to each operating torque measurement value according to the load flow.

[0121] Step S603: Calculate a first deviation between each operating torque measurement value and the theoretical operating torque.

[0122] Step S604: Filter out the first deviation that is greater than the allowable torque deviation.

[0123] Step S605: Accumulate the filtered first deviations that are greater than the allowable torque deviation to obtain a torque deviation accumulation value.

[0124] Step S606: Determine whether the torque deviation accumulated value is greater than or equal to the deviation threshold.

[0125] If the judgment result of step S606 is yes, execute step S607; otherwise, execute steps S601 to S606 again;

[0126] Step S607: setting the automatic lubrication flag to a first value to instruct the refueling device to start refueling the equipment.

[0127] In some embodiments, when the judgment result of step S606 is yes, the method further includes: generating torque abnormality alarm information so that relevant equipment maintenance personnel can promptly detect the oil shortage of the equipment.

[0128] Step S608: Evaluate the lubrication effect during the refueling process.

[0129] In some embodiments, using Figure 5 The partial process shown evaluates the lubrication effect during the oiling process.

[0130] Step S609: Determine whether the lubrication effect evaluation value is greater than or equal to the lubrication effect evaluation threshold.

[0131] If the judgment result of step S609 is yes, step S610 is executed; otherwise, steps S608 and S609 are executed again.

[0132] Step S610: setting the automatic lubrication flag to a second value to instruct the refueling device to stop refueling the equipment.

[0133] In the disclosed embodiment, the above steps can automatically and intelligently detect equipment oil shortages based on monitoring of the equipment's load flow and operating torque during operation, allowing for timely refueling and lubrication.
