Detailed Description
In a first aspect, an embodiment of the present application provides a track transportation electromechanical device distance repair optimization method, as shown in fig. 1, including the following steps:
and S100, acquiring a to-be-overhauled area.
Specifically, the area to be overhauled is a place where the maintainer is expected to go to overhaul, such as an XX subway station.
And S110, acquiring the equipment type of the rail transit electromechanical equipment based on the area to be overhauled.
Specifically, the type of the rail transit electromechanical device refers to a rail transit electromechanical device existing in a maintenance area, a device for maintaining normal operation of a subway station, an emergency fire-fighting device, or the like, such as an elevator.
And S120, obtaining a maintenance project based on the equipment type.
Specifically, a plurality of different faults can happen to one device, and the maintenance items are specific faults which occur or can occur to certain rail transit electromechanical devices, such as damage to a motor of an elevator or damage to a conveyor belt. The overhaul project can be preset according to faults which have occurred historically.
And S130, acquiring the maintenance time corresponding to the maintenance project based on the maintenance project.
Specifically, the overhaul time is that track traffic electromechanical device probably appears damaging in the operation process, and the maintenance time to the equipment of setting, the overhaul time of each kind of trouble is inequality, consequently, has different overhaul time to different trouble, and for example the overhaul time that the motor of elevator damaged is 3 months, and the overhaul time that the conveyer belt damaged is 2 months. The maintenance time idea is made according to the suggestion of a manufacturer and can also be made according to the system of each subway station.
And S140, acquiring the service life of the rail transit electromechanical equipment.
Specifically, the service life of the rail transit electromechanical device is the time from the production of the device to the present, and the factory time of the device can be acquired according to the nameplate of each device.
And S150, judging whether the service life is greater than a preset life.
Specifically, the preset age limit is the maximum time point at which the equipment is prone to failure after being used for a long time, and the specific time of the preset age limit can be obtained according to previous maintenance data or can be obtained according to the suggestion of a manufacturer.
And if the service life is less than or equal to the preset life, the operation is not carried out.
And S160, if the service life is greater than the preset service life, obtaining maintenance adjustment time based on the service life and the maintenance time.
Specifically, the maintenance adjustment time is according to the increase of the service life of equipment, adjusts on the maintenance time before, and maintenance adjustment time is less than maintenance time usually to the service life is longer, and it is shorter that it compares to overhaul its time length of adjustment time.
And S170, overhauling the rail transit electromechanical equipment based on the overhauling adjustment time.
The implementation principle of the embodiment is as follows: after the maintenance area is determined, the equipment type in the maintenance area is confirmed, namely, the fault equipment with faults is obtained, then the specific equipment type is obtained according to the fault equipment, then the specific maintenance items are obtained according to the specific fault equipment, each maintenance item corresponds to maintenance time, then the service life of the rail transit equipment is obtained, whether the service life is longer than the preset service life or not is judged, if the service life is longer than the preset service life, the maintenance time is adjusted according to the difference of the service lives to obtain maintenance adjustment time, and the rail transit electromechanical equipment is maintained according to the adjusted maintenance adjustment time. Therefore, the maintenance time of the equipment can be adjusted by combining the service life of the equipment according to different types of faults, the equipment can be maintained according to the adjusted maintenance time, the increase of the service time can be effectively prevented, and the probability of damage caused by improper equipment maintenance due to the fact that the maintenance time is not changed because the change of the equipment is not considered is reduced.
In one implementation manner of this embodiment, as shown in fig. 2, the step S130 of obtaining the repair time corresponding to the repair item based on the repair item includes:
s200, acquiring historical maintenance interval data of each rail transit electromechanical device based on the maintenance items.
Specifically, when the rail transit electromechanical devices are overhauled once, the interval time before two overhauls is two adjacent overhauls for a specific fault, for example, the motor of the elevator is overhauled, the last time is 10/10 th in 2021, and the next time is 11/10 th in 2021, so the interval time between overhauls is one month.
S210, sequencing the historical maintenance interval data of each rail transit electromechanical device to obtain a sequencing result.
Specifically, the sorting result is to sort the historical maintenance interval data according to the length of time, for example, the historical maintenance interval data is 28, 26, 27, 21 and 1, the units are days, and the historical maintenance interval data is 1, 21, 26, 27, 28 and 28 after being arranged in the descending order.
S220, screening the sequencing result to remove the screening removal value of the sequencing result, and obtaining the screening result.
Specifically, the screening removal value is some abnormal maintenance interval data existing in the screening sorting result, for example, 1 day in the above, normally, if a device is overhauled for two consecutive days, it is highly probable that the problem is not solved when the first overhaul is performed, so the next day is overhauled again, and it is meaningless for determining the overhaul time for such historical maintenance interval data, and therefore, the screening removal is required.
And S230, obtaining mode overhaul time based on the screening result, and taking the mode overhaul time as overhaul time corresponding to the overhaul project.
Specifically, the mode repair time is the historical repair interval data which appears most frequently in the historical repair interval data, for example, if 28 days in the above description appear twice, 28 is the mode repair time, and of course, in practice, determining the mode repair time requires more data, for example, the previous repair time of three years or 5 years, and the longer the time, the higher the accuracy.
The implementation principle of the embodiment is as follows: obtaining historical maintenance interval data of the rail transit electromechanical equipment according to the obtained maintenance items of the equipment, then sequencing the historical maintenance interval data, processing the sequenced sequencing result, removing part of special values to obtain a screening result, then obtaining the most-appeared mode maintenance time according to the screening result, wherein the mode maintenance time is the time with the most-appeared maintenance times, and the mode maintenance time is used as the maintenance time. According to historical maintenance data, the most time is taken as the maintenance time of the equipment, the maintenance time of most of the equipment can be guaranteed to meet the requirement, the problem that the maintenance is carried out at the shortest interval time to cause relatively large labor cost is solved, or the maintenance is carried out at the longest price time to cause relatively high probability of equipment damage.
In one implementation of this embodiment, as shown in fig. 3, the step S200 of acquiring historical maintenance interval data of each rail transit electromechanical device based on the service item includes:
s300, judging whether the rail transit machines and the electric machines are produced in the same batch.
Specifically, the rail transit electromechanical devices produced in the same batch are produced by the same manufacturer in the same batch, and the products produced in the same batch are closer to the products produced in different batches in performance and service life.
And if the rail transit equipment is not produced in the same batch, acquiring the rail transit electromechanical equipment produced by the same manufacturer.
Although the rail transit electromechanical equipment is not produced in the same batch, the rail transit electromechanical equipment is produced by the same manufacturer, and the performance of the rail transit electromechanical equipment is different.
And S310, if the rail transit electromechanical devices are produced in the same batch, judging that the rail transit electromechanical devices are used at the same station.
Specifically, in the case of the same batch production, if the equipment is used at the same station, the use environment of the equipment is the same, and in the case of the same batch and the same environment, the overhaul time of the equipment is certainly closer.
If the rail transit electromechanical equipment is not used at the same station, acquiring a suggested maintenance interval of the rail transit electromechanical equipment; the recommended maintenance interval is a recommended maintenance time interval of a manufacturer of the rail transit electromechanical equipment.
And S320, if the rail transit electromechanical equipment is used at the same station, acquiring historical maintenance interval data of each rail transit electromechanical equipment.
Specifically, the maintenance data of the equipment with the same factory performance and service environment of the equipment is used as historical maintenance interval data, and the accuracy is high.
The implementation principle of the embodiment is as follows: the equipment produced in the same batch has very close performance, if the equipment is used at the same station, the service environment of the equipment is the same, the overhaul time of the batch of equipment is the closest, the overhaul time of the equipment is determined according to the historical maintenance interval data of the batch of equipment, and the overhaul time is not too different for all the equipment, so that the overhaul efficiency is improved.
In one implementation of this embodiment, as shown in fig. 4, the step S150 of determining whether the service life is greater than the preset life includes:
s400, obtaining the maintenance record of each rail transit electromechanical device based on the device type.
Specifically, the maintenance record of the rail transit electromechanical device refers to a record of maintenance performed after the rail transit electromechanical device has a fault, rather than a record of maintenance. E.g. a damaged motor of the elevator replaces the motor and a worn belt replaces the belt seriously.
And S410, acquiring the maintenance times of the electromechanical equipment of the rail transit based on the maintenance record.
Specifically, the maintenance times refer to the times from the beginning of putting into use to the current maintenance of the rail transit electromechanical equipment. And after each maintenance, the maintenance time is recorded, and the maintained times can be obtained from the maintenance time.
And S420, judging whether the maintenance frequency is greater than the preset frequency.
Specifically, the preset number is a maximum number of times that the device is easily damaged due to an excessive number of times of maintenance, for example, the preset number is set to 5 times, and when the number of times of maintenance is greater than 5 times, it is determined that frequent maintenance is required.
And S430, if the maintenance times are larger than the preset times, marking the rail transit electromechanical equipment as service and maintenance equipment.
In particular, the service equipment is equipment which needs to be serviced more frequently than other equipment, that is, equipment which needs shorter service time.
And S440, acquiring preset overhaul time of the overhaul equipment.
Specifically, the preset maintenance time is the time for maintaining the service equipment, and due to the fact that the service equipment is easy to damage, the service equipment cannot be maintained for the same maintenance time as other equipment, and if the service equipment is maintained for the same maintenance time as other equipment, the service equipment is likely to be damaged.
And S450, overhauling the service and overhaul equipment based on preset overhauling time.
The implementation principle of the embodiment is as follows: for rail transit electromechanical equipment, maintenance is required when a fault occurs, if the maintenance frequency of one rail transit equipment is greater than the preset frequency, the equipment is easy to damage, and the damaged equipment is enabled to correspond to independent maintenance time, so that the equipment is marked as service maintenance equipment, the maintenance time of the service maintenance equipment is the preset maintenance time, and the service maintenance equipment is independently maintained according to the preset maintenance time, so that the maintenance efficiency is improved.
In one embodiment of this embodiment, as shown in fig. 5, the step S440 of acquiring the preset service time of the service equipment includes:
s500, obtaining the maintenance grade of the rail transit electromechanical equipment based on the equipment type of the equipment.
Specifically, the maintenance grade is the maintenance interval determined according to the importance degree of the equipment, and the higher the importance degree of the equipment is, the shorter the maintenance interval is.
And S510, if the service and maintenance equipment is in an important grade, acquiring first preset time as preset maintenance time of the service and maintenance equipment.
In particular, the important level is equipment which can affect the operation of the subway station after a fault occurs, such as an elevator, and the elevator can affect the access of people taking the subway after the fault occurs. The first preset time can be obtained according to the average value of the time intervals of the previous maintenance, and then the first preset time is advanced by several days on the basis of the average value, so that in case of accident, the maintenance time can also be set by self, and the set maintenance time is less than the time of the previous damage, for example, the minimum value of the time intervals of the previous maintenance is taken.
And S520, if the service maintenance equipment is in a common grade, acquiring second preset time as preset maintenance time of the service maintenance equipment, wherein the first preset time is less than the second preset time.
In particular, the general class is that equipment which does not have too great an effect on the normal operation of the subway station after a fault occurs, for example, lamps in the subway station, and after one lamp is damaged, other lamps are available, only the illumination intensity is reduced. The second preset time and the first preset time are obtained in the same mode.
The important grade or the common grade of the equipment can be recorded in advance, all the equipment which has influence on the operation of the subway station is recorded as important grade equipment, the equipment which has no influence is recorded as common grade equipment, and the common grade or the important grade can be known only by matching the name of the equipment with the recorded equipment name.
The implementation principle of the embodiment is as follows: in the maintenance of equipment on duty, according to the difference of equipment type, acquire the maintenance level of equipment, if the maintenance level of maintenance of equipment on duty is important grade, regard as preset maintenance time with first default time, if for general grade, regard as the preset maintenance time of equipment on duty with second default time, the time length of first default time is less than the time length of second default time, realize dividing different maintenance time according to different maintenance levels, and then can alleviate maintainer's operating pressure.
In one implementation of this embodiment, as shown in fig. 6, the step S420 of determining whether the number of repairs is greater than the preset number further includes:
s600, if the maintenance times are smaller than the preset times, judging whether the track traffic electromechanical equipment is subjected to disaster maintenance or not based on the maintenance records.
Specifically, the disaster repair specifically refers to that the rail transit electromechanical equipment is damaged due to a natural disaster, for example, the equipment is flooded, and by querying a maintenance record, the maintenance record may include the reason of the equipment fault, the maintenance time of the fault, the type of the fault, and the like.
And S610, if disaster overhaul is carried out, acquiring an overhaul grade.
Specifically, the maintenance grade is the degree of damage according to the influence of the disaster on the equipment. The degree of damage can be determined according to the number of parts to be replaced during maintenance of the equipment, for example, the replacement data exceeds a certain number or the replaced parts are core components of the equipment.
And S620, if the rail transit electromechanical equipment is seriously damaged, acquiring a maintenance strategy.
Specifically, when the serious damage is maintenance, the replaced devices or more devices or the core devices are replaced, a plurality of core devices of one device are possible, the influence on normal use is the core devices, for example, a gate for card swiping in and out of a subway station, if the gate is damaged, only hardware is damaged, the maintenance can be carried out simply, but if the card swiping device is damaged, the maintenance difficulty is very high, and the whole card swiping induction device is required to be replaced, so that the serious damage is caused. Also e.g. damaged in the motor of the elevator, is also a serious damage. The maintenance strategy is the selected maintenance time aiming at different damages of the equipment.
S630, overhauling the rail transit electromechanical equipment based on the maintenance strategy.
And S640, if the rail transit electromechanical equipment is damaged normally, stopping entering the next step.
Specifically, ordinary damage is very simple just can maintain, does not relate to the core part and damages, for example when the inspection is used for checking whether have contraband article in the subway station, the conveyer belt that is used for conveying article damages, only need change the conveyer belt can.
The implementation principle of the embodiment is as follows: if the track traffic equipment is overhauled in a disaster, namely the track traffic equipment is damaged in the disaster, the track traffic equipment is different from the equipment damaged in nature, for example, the performance of the track traffic equipment is much worse than that of the equipment damaged in nature, therefore, aiming at the special equipment, the overhauling mode of the track traffic equipment is obviously different from that of other equipment, the track traffic electromechanical equipment is overhauled according to the overhauling strategy by acquiring the corresponding overhauling strategy, and further the track traffic electromechanical equipment damaged in the disaster can be prevented from being overhauled together with other equipment, and the probability of damage is increased due to overlong overhauling time.

s700, when the rail transit equipment is in the important grade, acquiring historical maintenance interval time of the rail transit equipment which is seriously damaged in the same area to be maintained based on a maintenance strategy.
Specifically, when the rail transit equipment is of an important grade, due to disaster overhaul of the equipment, the performance of the equipment is definitely much poorer than that of the ordinary equipment and is important equipment, so that different overhaul time is required for other equipment when overhaul time is required. The historical overhaul interval time of the rail transit equipment which is seriously damaged in the same area to be overhauled is the historical overhaul time of the equipment of the same type in the same station after the damage of the disaster occurs.
And S710, obtaining average time of the overhaul intervals based on the historical overhaul interval time.
Specifically, the average time of the overhaul interval = sum of historical overhaul interval times/overhaul times, for example, the overhaul time is 20, 25, 32, then the average time of the overhaul interval is (20 +25+ 32)/3 =25.6, and actually when the overhaul time is calculated, an integer is taken upward, that is, 26 days. The average time between overhauls can satisfy the overhaul time of most equipment, if there is obvious abnormal data in the historical overhaul interval time, when calculating the overhaul interval abnormal time, need to remove the abnormal time, for example, the overhaul time is compared with other historical overhaul times, obvious time is longer or shorter.
S720, overhauling the rail transit electromechanical equipment based on the average time of the overhauling intervals.
The implementation principle of the embodiment is as follows: if the maintenance grade is an important grade, the equipment subjected to disaster overhaul is in an overhaul area, and the average time of overhaul intervals is used as the overhaul time of the seriously damaged equipment according to the historical overhaul interval time of the severely damaged traffic equipment. The time when the equipment in the same area is seriously damaged is basically the same time, and the average time is taken as the overhaul time, so that the overhaul of most of the equipment can be basically met. .

The category weighting factor may be set to a fixed value, for example, 1 for a general class of devices and 0.7 for an important class of devices.
And S820, obtaining maintenance adjustment time based on the age limit weight, the maintenance time and the category weight.
Specifically, the repair adjustment time = repair time × age limit weight × category weight, and if the repair time is set to T1 and the repair adjustment time is set to T2, then T2= T1 × X × Y.
The implementation principle of the embodiment of the application is as follows: with the increase of the service time, the overhaul time is shorter and shorter, the importance degree of the equipment is different, and the more important equipment, the overhaul time should be shorter, so different weights are divided, and the overhaul adjustment time is obtained comprehensively according to the weight result.

Specifically, the newly added maintenance items are new faults which do not exist in the existing maintenance items, and the similarity between the newly added maintenance items and the maintenance items is that although the newly added maintenance items and the existing maintenance items are not the same faults, the reasons for the faults are similar, for example, the faults are all voltage faults or short-circuit faults. For example, if a water inlet fault, a voltage fault and a heat generation fault occur in a certain device once, and a new maintenance item is added due to the water inlet fault and the voltage fault, the similarity is 2/3.
S910, obtaining the maximum similarity.
Specifically, the maximum similarity is the maximum similarity obtained in the results of comparison with all the overhaul items, for example, there are 3 overhaul items, and the similarities are 2/3,3/4, and 4/5, respectively, so that the maximum similarity is 4/5.
And S920, determining the corresponding overhaul item as a target overhaul item based on the maximum similarity.
Specifically, a maintenance item with the similarity of 4/5 to the newly added maintenance item is obtained as a target maintenance item, and the target maintenance item is used for determining the maintenance time of the newly added maintenance item.
