Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The systematic maintenance method for spare parts of a nuclear power plant provided by this embodiment can be applied to the application environment shown in fig. 1, in which a client communicates with a server. The client includes, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server can be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, a systematic maintenance method for spare parts of a nuclear power plant is provided, which is described by taking the method as an example of being applied to a service end in fig. 1, and includes the following steps:
and S10, obtaining maintenance information of a plurality of spare parts.
In this embodiment, the maintenance information may be from a product maintenance manual provided by the supplier, or may be determined based on the physical and chemical properties of the spare parts, and the time during which the mass changes during storage. In some cases, the service information for the spare part may also include quality assurance information for the material used to protect the spare part, and may also include quality assurance information for the material used to package the spare part. The service information also includes a prior service record of the spare part.
And S20, dividing maintenance grades according to the maintenance information, wherein each spare part corresponds to one maintenance grade.
The spare parts may be divided into a plurality of maintenance classes according to the frequency of maintenance. For example, the service level may include high frequency, medium frequency, and low frequency. In some cases, the same service level is further divided into two different service characteristics for determining the adjustability of the service frequency of the spare parts. In determining the adjustability of the maintenance frequency, the degree of dispersion (e.g., variance) of the maintenance frequency of the spare part may be calculated based on the previous maintenance record, and the calculated degree of dispersion may be compared to an adjustment threshold. For example, an adjustment threshold may be set, above or equal to which adjustable maintenance is set, below which non-adjustable maintenance is set. The adjustment threshold may be set as desired.
And S30, acquiring the number of all spare parts in each maintenance grade and the maintenance man-hour data.
Generally, the maintenance frequency of spare parts with the same maintenance grade is basically close, and the maintenance treatment can be carried out in the same batch. The number of all spare parts and the maintenance man-hour data in the maintenance grade are obtained, and the workload of one maintenance work can be determined. Each spare part has its corresponding maintenance man-hour data. For example, spare part M1, maintenance man-hour data is 10 minutes; spare part M2, maintenance man-hour data was 20 minutes.
And S40, generating a maintenance plan according to the number and the maintenance man-hour data.
When a maintenance plan is created, if the number of available man-hours is not limited, the maintenance plan can be created directly from the number of spare parts and the maintenance man-hour data. For example, if spare part MiIs niThe corresponding maintenance man-hour data is qi(here q isiAverage maintenance time for each spare part), the total number of types of the spare parts is t, and the total maintenance man-hour is:
when the number of available man-hours is limited, the spare parts with high frequency and the spare parts which are not allocated in the previous maintenance plan are preferentially allocated for maintenance. Illustratively, if the total maintenance time is 1000 hours, and the available time is only 800 hours, the spare parts with low priority can be automatically deleted (and a mark is added so that the next maintenance can be performed with priority), so that the total maintenance time is less than 800 hours. In some cases, the service level may be used to determine a service priority for the spare part.
The maintenance plan includes information on a plurality of spare parts requiring maintenance. In some cases, specific staff allocation information may also be included.
And S50, sending the maintenance plan to a designated worker.
The maintenance plan may be sent to a designated staff member for performing maintenance work by the designated staff member according to the maintenance plan. The maintenance schedule may include maintenance procedures and precautions for the spare parts. According to incomplete statistics, after the systematic maintenance method for the spare parts of the nuclear power plant provided by the embodiment is implemented, the total maintenance man-hour is reduced by 30% on the premise of not reducing the maintenance quality.
In steps S10-S50, maintenance information of a plurality of spare parts is obtained to obtain maintenance characteristics of each spare part. According to maintenance information divides the maintenance grade, every the spare part corresponds a maintenance grade, through the maintenance grade of confirming the spare part, reduces the maintenance degree of difficulty of spare part (the staff need not know the maintenance characteristic of every spare part, and only need know its maintenance grade can), improves the maintenance efficiency of spare part. And acquiring the quantity of all spare parts and maintenance man-hour data in each maintenance grade to evaluate the workload of the spare parts. And generating a maintenance plan according to the quantity and the maintenance man-hour data so as to automatically generate the maintenance plan, and saving the time for setting the maintenance plan by the staff. And sending the maintenance plan to a designated worker, so that the designated worker receives the maintenance plan, and the designated worker can maintain the spare parts according to the maintenance plan.
Optionally, as shown in fig. 3, in step S20, the dividing service levels according to the service information, where each spare part corresponds to one service level, includes:
s201, inputting the maintenance information into a preset equipment maintenance grade evaluation model;
s202, obtaining the maintenance grade of the spare part output by the spare part maintenance grade evaluation model.
In this embodiment, the spare part maintenance level evaluation model may be constructed according to preset maintenance constraint conditions. For example, a previous maintenance record of the spare part may be collected, the maintenance time of the spare part may be processed into a maintenance sample according to the previous maintenance record, and then the maintenance sample may be processed by an existing clustering algorithm, so as to calculate a spare part maintenance grade evaluation model with an optimal result.
In some cases, the service information may refer to process flow information for the spare part. In this case, the spare part maintenance level evaluation model is used to evaluate the similarity of the processing flows between the spare parts. Spare parts having similar process flows may be classified as having the same maintenance level.
Optionally, as shown in fig. 4, before step S30, that is, before the acquiring the number of all spare parts and the maintenance man-hour data in each of the maintenance classes, the method further includes:
s31, acquiring a previous maintenance record of the specified spare part;
s32, generating maintenance man-hour distribution data of the specified spare part according to the prior maintenance record;
and S33, processing the maintenance work hour distribution data based on a preset statistical method, and generating the maintenance work hour data of the specified spare part.
In this embodiment, the previous maintenance record details the maintenance start time, the maintenance end time, and the maintenance amount of the designated spare part. In the first maintenance record, the recording precision of the time can be accurate to minutes or even seconds.
The maintenance man-hour distribution data may be generated based on a previous maintenance record of a specified spare part. Illustratively, the maintenance man-hour distribution data may be expressed as:
designating spare part a:
amount 18, time 13 minutes;
amount 25, time 19 minutes;
……。
the predetermined statistical method may be determined based on actual conditions. For some spare parts, the maintenance man-hour data is linearly proportional to the number, and the relationship between the maintenance man-hour data and the number of the spare parts can be directly solved by using a unitary equation (the constant term is not zero) or an average value.
For other spare parts, the maintenance man-hour data is in nonlinear proportion to the number, and at this time, the maintenance man-hour distribution data needs to be counted, the probability distribution of the maintenance man-hour data spent in different numbers is calculated, and the maintenance man-hour data (which may be the total number of man-hours or the average number of man-hours per designated spare part) of the currently designated spare part is calculated.
Alternatively, as shown in fig. 5, the step S40 of generating the maintenance plan according to the number and the maintenance man-hour data includes:
s401, establishing a maintenance task for maintaining the spare part;
s402, acquiring the deadline of the spare parts in the maintenance task, and setting the deadline closest to the time as the task deadline of the maintenance task;
s403, calculating total maintenance man-hour according to the number of spare parts in the maintenance task and the maintenance man-hour data;
s404, generating task time information of the maintenance task according to the task time limit and the maintenance total man-hour; the maintenance plan includes at least one of the maintenance tasks.
In this embodiment, a maintenance task may include one or more spare parts requiring maintenance. The number of maintenance tasks may also be one or more.
The end-of-service life typically varies from one spare part to another. The most proximate in time deadline may be selected and set as the maintenance task deadline. For spare parts with non-adjustable adjustability, the end-to-end service life is: the end-of-service period is the last time of service plus the service period. That is, the adjustability is not adjustable spare parts, and the last maintenance time is 1/3/2020, and the maintenance period is 6 months, and the end-to-end maintenance period is 7/3/2020. That is, the spare part requires a further maintenance before 7/3/2020.
For spare parts with adjustable adjustability, the end-to-end service life is as follows: the end-of-service period is the last service time + the service period + the adjustable time. That is, the adjustable degree of the spare parts is adjustable, the last maintenance time is 1 month and 3 days in 2020, the maintenance period is 6 months, and the adjustable time is 2 months, and the final maintenance period is 9 months and 3 days in 2020. That is, the spare part requires a further maintenance before 9/3/2020.
The total maintenance man-hour of each maintenance task can be calculated according to the number of spare parts and the maintenance man-hour data in each maintenance task. For example, the total number of maintenance hours for maintenance task 1 is equal to the sum of the maintenance hours for all of the spare parts in maintenance task 1, and the maintenance hours for each type of spare part is equal to the average maintenance time for a single spare part of that type multiplied by the number of spare parts of that type.
After the task time limit and the maintenance total man-hour are calculated, the task time information can be automatically generated. For example, if the number of maintenance man-hours of a maintenance task is calculated to be 40 man-hours and the number of persons to be distributed is 2, the maintenance time of the maintenance task is two and a half days, and if the task period is 10 days, 2.5 days can be arbitrarily selected within the 10 days for processing the maintenance task. Typically, 2.5 days are taken as a continuous time interval.
Optionally, as shown in fig. 6, after the step S50, that is, after the sending the maintenance plan to the designated staff member, the method further includes:
s60, acquiring the execution information of the maintenance plan;
and S70, processing the execution information according to a preset analysis model to generate a maintenance result.
In this embodiment, the execution information includes the actual completion status of the maintenance task, including but not limited to the number of spare parts and the time for completing the maintenance.
The preset analysis model can arrange the execution information to generate a maintenance result. The maintenance result can be a statistical chart or formatted data such as a report. Here, presetting the parsing model is equivalent to providing a formatted template, and automatically extracting data from the execution information and filling the data to an appropriate position in the template. In one example, the maintenance results include, but are not limited to, completion rate of maintenance tasks, punctual rate.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
