s304, if the number of the preselected overhaul task items is multiple, obtaining overhaul data differences corresponding to the preselected overhaul task items;

s305, selecting a preselected maintenance task item with the largest maintenance data difference as a set maintenance task item, and matching corresponding target components in a vehicle bogie according to the set maintenance task item;

s306, recording a priority overhaul list corresponding to the target part to the bogie of the vehicle.

In practical application, in order to conveniently trace the bogie maintenance task items before and after the change, corresponding node change records are generated according to the current bogie maintenance task item and the bogie maintenance change task item corresponding to the bogie maintenance task item.

For example, the repair frequency corresponding to the bogie repair task item S is 1 time in 2 weeks, and after modification and adjustment of the repair process standard corresponding to the bogie repair task item S, the repair frequency corresponding to the bogie repair change task item corresponding to the bogie repair task item S is 1 time in 1 week, and the node change record corresponding to the modification is generated as follows: the maintenance frequency of the bogie maintenance task item S is changed to 2 weeks 1 maintenance and changed to 1 week 1 maintenance of the bogie maintenance task item S, so that relevant maintenance personnel can conveniently obtain the change condition of the maintenance frequency corresponding to the bogie maintenance task item S.

If the node change records are multiple, the change times corresponding to the bogie maintenance task items in the node change records are obtained, the more the change times are, the more the fault problems of the bogie components corresponding to the bogie maintenance task items are, and in order to improve the safety of the bogie components with more fault problems, the bogie maintenance task items with the largest change times are further obtained to be preselected maintenance task items, and the related maintenance personnel pay more attention to the bogie components to be detected according to the preselected maintenance task items.

If the node change record is single, directly acquiring the corresponding bogie maintenance task item and the maintenance component corresponding to the bogie maintenance task item in the node change record, and displaying the bogie maintenance task item and the maintenance component to related maintenance personnel through a station billboard.

Further, if the number of the preselected maintenance task items is multiple, the maintenance data difference corresponding to the preselected maintenance task items is obtained, the preselected maintenance task item with the largest maintenance data difference is selected as a set maintenance task item, the corresponding target component in the vehicle bogie is matched according to the set maintenance task item, the matched target component is recorded to a priority maintenance list corresponding to the vehicle bogie, and the priority maintenance list can be sent to a handheld maintenance terminal of a corresponding maintenance staff through a station signboard or a wireless transmission mode. The larger the overhaul data difference is, the higher the failure rate of the bogie component is, and the purpose of selecting the preselected overhaul task item with the largest overhaul data difference as the set overhaul task item is to improve the attention of related personnel to the bogie component with the higher failure rate, namely the target component, and reduce the occurrence of safety accidents of vehicles in operation.

And if the preselected maintenance task items are single, displaying the maintenance task items and the maintenance components corresponding to the bogie maintenance task items to related maintenance personnel through the station signboards directly according to the bogie maintenance task items corresponding to the preselected maintenance task items.

According to the vehicle bogie overhauling method, according to the priority overhauling list, the target part with the largest number of times of change of bogie overhauling task items and the largest corresponding overhauling data difference in the vehicle bogie can be obtained, so that vehicle bogie parts with serious abnormal problems can be conveniently screened out in time for relevant overhauling staff to pay attention in advance, and the overhauling safety of the vehicle bogie parts is improved.

In one implementation manner of the present embodiment, as shown in fig. 4, step S306, that is, recording a priority service list corresponding to the target component to the vehicle bogie, includes the following steps:

s401, if a plurality of target components are provided, obtaining damage predicted values corresponding to the target components;

s402, setting a first overhaul ranking of each target component according to the damage predicted value, wherein the higher the damage predicted value is, the higher the first overhaul ranking corresponding to the target component is;

s403, if the first overhaul ranking grades of the target components are the same, acquiring the target failure rate corresponding to the target components;

s404, setting the higher the target failure rate of the second overhaul ordering ranking of the target component according to the target failure rate, wherein the higher the second overhaul ordering ranking corresponding to the target component is;

s405, recording a priority overhaul list corresponding to the target component to the vehicle bogie by combining the first overhaul sequencing ranking and the second overhaul sequencing ranking.

In practical application, in order to improve safety detection of a vehicle bogie component, comprehensive evaluation needs to be performed by combining damage pre-evaluation values of all components in the vehicle bogie, namely target components, the damage pre-evaluation values can also be life tests of the vehicle bogie component, wherein the larger the damage pre-evaluation value corresponding to the vehicle bogie component is, the shorter the corresponding life is, in order to increase safety overhaul strength of the vehicle bogie component, the corresponding first overhaul ranking order is set according to the damage pre-evaluation value corresponding to the vehicle bogie component, the larger the damage pre-evaluation value is, the higher the first overhaul ranking order corresponding to the target components is, and the system outputs the target component with the highest ranking in the first overhaul ranking order preferentially.

Further, if the first overhaul ranking grades corresponding to the plurality of target components are the same, obtaining a target failure rate corresponding to each target component, wherein the higher the target failure rate is, the worse the stability of the target component in the corresponding vehicle bogie is, the target failure rate corresponding to the target component can be obtained through historical overhaul data, further setting a second overhaul ranking grade corresponding to the target component according to the obtained target failure rate, and recording the priority overhaul lists corresponding to the vehicle bogie from each target component by combining the obtained first overhaul ranking grade and the obtained second overhaul ranking grade.

And if the first overhaul ranking grades corresponding to the target components are different, ranking the target components directly according to the first overhaul ranking grades corresponding to the target components, and recording the first overhaul ranking grades to a priority overhaul list corresponding to the vehicle bogie.

According to the vehicle bogie overhauling method, all target components are overhauled in sequence according to the priority overhauling list, so that the target components with serious hidden danger can be overhauled and removed in time, and the safety and overhauling efficiency of all the components in the vehicle bogie are improved.

In one implementation manner of the present embodiment, as shown in fig. 5, in step S301, after generating the corresponding node change record according to the bogie maintenance task item and the bogie maintenance change task item corresponding to the bogie maintenance task item, the method further includes the following steps:

S501, acquiring corresponding fluctuation feedback information according to the node fluctuation record;

s502, if the variable feedback information is a plurality of pieces, obtaining the support rate corresponding to each variable feedback information;

s503, setting feedback priorities corresponding to various variable feedback information according to the support rate, wherein the support rate and the feedback priorities are in a direct proportion relation;

s504, outputting various fluctuation feedback information according to the feedback priority.

In practical application, corresponding change feedback information is recorded in node change records corresponding to bogie maintenance task items, the change feedback information refers to processing suggestions of related maintenance personnel on bogie maintenance change task items, and because the bogie maintenance change task items are mostly generated through system matching comparison judgment and lack of practical experience of the related maintenance personnel, the maintenance personnel can indicate own views and suggestions in the form of change feedback information according to bogie maintenance change task items generated by the system, so that the related management scheduling personnel can reference and reasonably adjust corresponding bogie maintenance plans.

If the number of the variable feedback information is multiple, in order to screen out the more valuable feedback information, the support rate corresponding to each variable feedback information is obtained, the support rate can be expressed by the number of praise comments corresponding to each variable feedback information, the support rate corresponding to the number of praise comments is higher, and on the other hand, a plurality of maintenance staff with the same view to the variable feedback information can indicate own intention in a praise comment approval mode.

Further, according to the support rate corresponding to the variable feedback information, setting the feedback priority corresponding to each variable feedback information, wherein the support rate is in a proportional relation with the feedback priority, and outputting each variable feedback information according to the feedback priority, wherein the feedback priority corresponding to the higher the support rate is higher, so that when the network communication is in an intermittent fault or delay state, the variable feedback information with the higher feedback priority is preferentially output.

According to the vehicle bogie overhauling method, when network faults or network delays are encountered, various change feedback information can be output according to the feedback priority, so that change feedback information with higher quality can be output preferentially, and analysis and reference can be carried out by related staff.

In one implementation of the present embodiment, as shown in fig. 6, step S108, that is, associating the modified maintenance schedule and the bogie model, generating the corresponding target schedule includes the following steps:

s601, acquiring an overhaul procedure corresponding to the model of the bogie according to a changed overhaul plan;

s602, analyzing the overhaul process to obtain a corresponding overhaul sub-process;

s603, identifying an overhaul sub-process, and obtaining overhaul components corresponding to the vehicle bogie;

S604, matching corresponding overhaul tool component libraries according to overhaul components;

and S605, allocating corresponding tool parts according to the overhaul tool part library to overhaul the vehicle bogie.

The overhaul process in step S601 refers to each flow link in the overhaul process flow corresponding to the change overhaul plan. For example, the repair process flow corresponding to the bogie in the variable repair plan is: warehousing, cleaning and drying a motor car bogie; the parts of the bogie of the motor car are disassembled; checking, performance testing and maintaining each part of the bogie after decomposition; assembling a motor car bogie in a production line; and after the assembly of the motor car bogie is completed, the performance of the whole bogie is tested, wherein the warehouse-in cleaning and drying of the motor car bogie are an overhaul process.

Further, the current maintenance procedure is analyzed, and corresponding maintenance sub-procedures are obtained, wherein the maintenance sub-procedures refer to all maintenance sub-procedures included in the maintenance procedure. For example, the inspection of each component of the bogie after disassembly, the performance test and the maintenance, wherein the inspection of each component, the performance test of each component and the maintenance of each component, that is, the inspection of each component of the bogie after disassembly, the performance test and the maintenance sub-process corresponding to the maintenance sub-process.

After the obtained maintenance sub-procedure is obtained and identified, a maintenance component corresponding to the vehicle bogie is obtained, a corresponding maintenance tool component library is matched according to the maintenance component, maintenance tools and replacement components corresponding to the maintenance component are displayed in the maintenance tool component library, and the obtaining positions corresponding to the maintenance tools and the replacement components are further allocated to related maintenance staff according to the maintenance tool component library, the maintenance staff overhauls the vehicle bogie according to the allocated maintenance tools or replacement components, and corresponding allocation records are recorded in the system, so that the maintenance tools and the replacement components are conveniently traced.

According to the vehicle bogie overhauling method, tool components corresponding to all overhauling components of the vehicle bogie are allocated according to the overhauling tool component library, the overhauling components and the obtaining efficiency of the corresponding overhauling tools are improved, and the overhauling efficiency of the overhauling components is further improved.

In one implementation manner of this embodiment, as shown in fig. 7, after step S604, that is, according to the service component, matching the corresponding service tool component library further includes the following steps:

S701, judging whether the overhauling part needs to be replaced or not;

s702, if the overhauling parts need to be replaced, acquiring the replacement number of the parts corresponding to the overhauling parts;

s703, judging whether the corresponding part stock quantity in the overhaul tool part library is larger than the part replacement quantity;

s704, if the corresponding part stock quantity in the overhaul tool part library is smaller than or equal to the part replacement quantity, generating a to-be-reserved quantity corresponding to the overhaul part;

and S705, storing the overhaul components according to the to-be-stored quantity.

In practical application, in order to reduce the occurrence of the condition that related replacement resources are lack due to the need of replacement of related components in the process of repairing the vehicle bogie, firstly judging whether the repairing components of the bogie need to be replaced according to the repairing data of the vehicle bogie, if so, acquiring the replacement quantity of the components corresponding to the repairing components, further judging whether the corresponding component stock quantity in the repairing tool component library is larger than the replacement quantity of the components, and displaying the residual stock quantity corresponding to each component in the vehicle bogie, namely the component stock quantity, in the repairing tool component library.

Further, if the inventory of the corresponding parts in the overhaul tool part library is smaller than or equal to the replacement number of the parts, the inventory corresponding to the overhaul parts is insufficient, then the to-be-reserved quantity corresponding to the overhaul parts is generated, the to-be-reserved quantity refers to the quantity of each part in the bogie of the vehicle, which is reserved by taking the target scheduling plan as a standard, and then the corresponding overhaul parts are reserved according to the to-be-reserved quantity.

According to the vehicle bogie overhauling method, if the corresponding part stock quantity in the overhauling tool part library is smaller than or equal to the part replacement quantity, the fact that the stock quantity of the vehicle bogie parts is insufficient is indicated, and relevant overhauling parts are further reserved according to a responsive plan to be reserved, so that the occurrence of the condition of halting overhauling caused by the fact that the vehicle bogie parts are insufficient is reduced, and normal overhauling is guaranteed.
