Fig. 1 is a schematic flow chart of a method for managing a worn component according to the present invention. The method for managing the worn components according to the embodiment of the present invention is described below with reference to fig. 1. As shown in fig. 1, the method includes: step 101, responding to a leasing request, and determining a part combination comprising a plurality of worn parts according to the leasing request.
A user input or a lease request sent through a user terminal is received.
The lease request may carry information required by the user. User requirements may include, but are not limited to, application project conditions, operating conditions requirements, load size, lease time, and the like.
After receiving the lease request, a plurality of part combinations matched with the user requirements can be generated according to the information of the user requirements and the information of each loss part in stock.
For example: under the condition that the loss part is the arm support, the heavy-load recommendation user rents the arm support with higher health degree, so that the safety is ensured; the lightly loaded recommended user rents the arm support with lower health degree, and the cost is reduced.
Several kinds refer to one or more.
Each component combination comprises a plurality of loss components.
Several, one or more.
The plurality of component combinations may be recommended to the user by a lease confirmation request carrying information using the plurality of component combinations.
If only one combination of the parts is generated, the renting confirmation information or the renting abandoning information input by the user or sent by the user terminal can be received; if the generated part combination is multiple, the user input or the confirmed lease information for confirming one part combination or the release lease information sent by the user terminal can be received.
After receiving the confirmed rental information, a rental order can be generated, and a plurality of worn parts included in the confirmed part combination are taken out of the warehouse for the user to use.
The user can also check the quotation and health degree of the stocked parts, the allocation cycle of the stockless parts and the like through the app or the webpage, freely select and allocate in the combination rule of the parts, and input or send a lease request carrying the information of the part combination through the user terminal. After receiving the lease request, determining a part combination comprising a plurality of worn parts according to the information of the part combination carried by the lease request, generating a lease order, and taking the plurality of worn parts comprised by the part combination out of the warehouse for the user to use.
For example, in the case that the loss component is an arm rest, the combination rule of the arm rest may include, but is not limited to: the arm head required for specific working conditions, specific length combinations of several types and the like.
And 102, if the lease ending message is received, acquiring the health degree of each loss part after the lease is ended.
Specifically, after the rental is finished, a rental finish message input by the user or sent through the user terminal, or a rental finish message input by the staff or sent through the terminal may be received.
After receiving the lease end message, the use of each worn component is ended, and the health degree of each worn component in this case can be acquired.
The health degree of each worn part after the rental can be acquired based on any one of an S-N metal stress fatigue analysis method, a method using a metal detector, reagent detection, appearance observation, and the like.
Such methods may include, but are not limited to, the use of metal detectors, reagent detection, or visual inspection.
And 103, determining the rental cost of the part combination according to the change of the health degree of each lost part during the rental period, the rental period and the initial health degree.
Wherein the initial health of the plurality of worn parts is obtained prior to receiving the lease request.
Specifically, the conventional management method for the shared device (such as a car, a bicycle, or a charger, etc.) generally determines the rental fee based on the length of the rental period.
In the embodiment of the invention, the leasing cost is determined and flexible charging is realized based on the leasing duration (namely the leasing period) and the change condition of the health degree of the worn parts during the leasing.
For example: the higher the initial health degree, the longer the rental time, or the greater the change in health degree before and after rental, the higher the rental fee.
For each worn part, the health of the worn part during the rental period can be determined based on the health of the worn part before and after the rental.
The change of the health degree of the worn parts during the leasing can include that the health degree grade before the leasing is higher than the health degree grade after the leasing.
The loss parts work in a severe environment for a long time, and the evaluation of the health degree of the loss parts is a key problem which is full of challenges and needs to be solved urgently, and is also a core technical problem for realizing the loss parts. Knowing the health degree of the worn parts, the method can take measures in a targeted manner to realize zero inventory and light inventory.
According to the method for managing the loss parts, provided by the embodiment of the invention, the user can rent the loss parts of the shared warehouse near the working point, and the loss parts do not need to be transported any more during transfer, but rent near the working point.
After a lease contract is signed with a user or a lease order is generated, estimating the loss degree of the loss parts according to the future workload, and collecting a certain proportion of fixed money; and after the leasing is finished, final evaluation is carried out, and the rest is collected.
Before leasing, that is, before receiving a lease request, the health of each worn component in the component assembly may be obtained as the initial health of the worn component.
For any worn part in the part combination, in the case where the worn part is leased before the worn part is leased, the initial health degree of the worn part obtained before lease may be the health degree of the worn part obtained after the last lease of the worn part is finished; when the worn component has not been leased before, the health degree of the worn component may be acquired as the initial health degree of the worn component by any of a S — N metal stress fatigue analysis method, a method using a metal detector, reagent detection, appearance observation, and the like.
The embodiment of the invention manages the loss parts based on the change of the health degree of each loss part during the lease period, can realize the sharing of the loss parts in a lease mode, can reduce the transportation and purchase cost of customers, can save resources, and can improve the management efficiency and the use efficiency of the loss parts.
Based on the content of any embodiment, the specific step of obtaining the health degree of each worn part after the rental includes: for each worn part, a first evaluation result of the health degree of the worn part under the non-working condition after leasing is finished is obtained based on a preset method.
Specifically, for each lossy member, after the operating condition is over, the lossy member is in the inoperative condition.
In this case, the degree of health of the worn component may be evaluated by a detection instrument (e.g., a metal detector or a reagent) and/or by visual observation, and a first evaluation result of the worn component may be obtained.
And acquiring the health degree of the worn parts after the leasing is finished based on the first evaluation result and/or the acquired second evaluation results.
And the second evaluation result is the evaluation result of the health degree of the worn parts obtained under the working condition during the leasing.
Specifically, after obtaining the first evaluation result, the first evaluation result and each evaluation result (i.e., the second evaluation result) of the health degree of the worn component under the operating condition are fused as the final health degree evaluation result (i.e., the health degree after the rental is finished).
During the lease period of each loss part, the health degree of the loss part under the working condition can be evaluated at each target time in the lease period, and a second evaluation result of the loss part at the target time can be obtained.
Optionally, after obtaining the first evaluation result, the first evaluation result may be used as the health of the worn component after the rental is finished.
Optionally, for each worn-out part, the health degree of the worn-out part after the rental is finished may be further obtained according to the second evaluation result of the worn-out part.
For example, the second evaluation results may be fused to obtain the health degree of the worn component after the rental is finished; the second evaluation result of the last target time may also be used as the health of the worn component after the rental is finished.
According to the embodiment of the invention, the health degree evaluation result of the loss part under the non-working condition after the working condition is finished is obtained by integrating the health degree evaluation result of the loss part under the non-working condition and the health degree evaluation result under the non-working condition, so that the health degree of the loss part can be more accurately evaluated.

Specifically, during the rental period of each worn component, the health of the worn component under the operating condition may be evaluated at each target time during the rental period, and a second evaluation result of the worn component at the target time may be obtained.
The target time may be each time and the use termination time determined according to a preset condition, may be each time and the use termination time at which any environmental data or any operating condition data changes, and may include only the use termination time.
The use termination time may refer to the end time of the last operation of the worn part during rental.
The respective times determined according to the preset conditions may be respective times determined according to a preset time interval or one time selected for each job.
And acquiring the health degree of each worn part at each target moment during the lease period, so that the change of the health degree of the worn parts can be acquired in time.
After the health degree of each worn part at each target moment in the rental period is obtained, the real-time health degree of the worn part at the target moment can be sent to the user terminal to inform the user.
It should be noted that, after obtaining the second evaluation result, the method may further include: and at each target moment in the lease period, if judging that the health degree of any lost part at the target moment is lower than a preset health degree threshold value, sending alarm information to a user terminal to prompt a user that the health degree of the lost part falls to disqualification.
The health degree threshold value can be set according to actual conditions, and specific values of the health degree threshold value are not limited in the embodiment of the invention.
For example, the health degree threshold may be set to 60, 50, 40, or the like, with the number of percentage points corresponding to the ratio of the remaining usage time to the theoretical usage life as the health degree.
The specific steps of obtaining the second evaluation result of the loss component part comprise: and for each loss part, acquiring environmental data, working condition data and stress data of the loss part at the target moment under the working condition.
And particularly, the environmental data is used for describing the environmental characteristics of the hoisting operation of the worn parts.
The environmental data may include at least one of temperature, humidity, wind speed of the work site, and data of whether the work site is a special area (e.g., a chemical region, a desert, a plateau, an island of a sea, etc.).
Depending on the actual situation, the current temperature, humidity, and wind speed may be real-time values at the time of work, or may be an average value (for example, a yearly average value or a monthly average value) of a certain time period to which the work time belongs at the work site.
The operating condition data indicates the combination condition of the loss components, and may include the use of only the main arm, the use of the main arm and the sub-arm, and the like.
And the stress data is used for describing the mechanical characteristics of the loss part in the process of carrying out lifting operation.

The health degree evaluation model is obtained after training based on the environmental data, the working condition data and the stress data of the part sample and the health degree corresponding to the environmental data, the working condition data and the stress data of the predetermined part sample.
Specifically, the current environmental data, the current working condition data, and the current stress data of the loss component may be used as inputs of a health degree evaluation model, and the inputs may be input to the health degree evaluation model, and the health degree evaluation model may output an evaluation value of the health degree of the loss component as an evaluation result of the current health degree of the loss component.
In the embodiment of the invention, the health degree can be the remaining life or the grade of the remaining life.
In the embodiment of the invention, the residual service life can represent the ratio of the residual service time to the theoretical service life.
