Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
FIG. 1 is a flow chart illustrating a nuclear plant pre-maintenance project overdue warning method according to an exemplary embodiment. The embodiment of the present disclosure may be applied to an intelligent terminal such as a notebook computer, a desktop computer, or a server, and the embodiment of the present disclosure does not limit this. As shown in fig. 1, the method may include:
step 100, judging the relation between the executed condition of the first item and a plurality of preset conditions;
step 101, determining an expiration degree corresponding to a first item according to an expiration determining mode corresponding to a matched preset condition when the executed condition of the first item is matched with one preset condition in a plurality of preset conditions;
step 102, judging whether the determined time-out degree is matched with a preset time-out condition;
and 103, carrying out overdue reminding under the condition that the overdue degree does not match a preset overdue condition.
In the embodiment of the present disclosure, the first item, the second item and the third item are all used for representing the preventive maintenance items of the nuclear power plant, wherein the first item, the second item and the third item are only used for representing different items, and no other special meaning is provided.
The preventive maintenance projects of the nuclear power plant need to be performed periodically, and therefore, it is necessary to constantly monitor whether each preventive maintenance project is overdue.
As an example of the present embodiment, the executed state of each first item may include any one or more of whether the first item is executed successfully, whether the first item is executed for the first time, and the like. The controller may pre-store a plurality of different preset conditions, where each preset condition may be used to describe a state in which a first item is executed, each preset condition may correspond to an expiration determination manner, and the expiration determination manners corresponding to different preset conditions may be the same or different. The controller may acquire, for one or more first items, an executed state of each first item, and determine a relationship between the executed state of each first item and a plurality of preset conditions, and when the executed state of the first item matches one of the preset conditions, may determine an expiration degree of the first item using an expiration determination manner corresponding to the matched preset condition, where the expiration degree may be represented as a degree that a current date of the system exceeds a date on which the first item needs to be executed, for example, the expiration degree may be an expiration percentage, and the expiration degree may also be an expiration number of days, and the like.
The controller may further pre-store a preset timeout condition, where the preset timeout condition may include one or more value ranges of the timeout degree, for example, the preset timeout condition may be that the timeout degree is greater than 25%, and the controller may perform timeout reminding when it is determined that the timeout degree matches the preset timeout condition, for example, the controller may send a reminding mail or display a list of corresponding first item information. The embodiment of the present disclosure does not limit the content of the overdue reminder. Fig. 3 is a schematic diagram of an expiration reminder mail according to an application example, and as shown in fig. 3, an expiration reminder mail may be sent to a person in charge associated with a first project, and the content of the reminder mail may include a number of the first project confirming the expiration, a work order task number, a job type, a work order task description, a predicted due date, a number of days of expiration, an expiration percentage, and the like. Plan engineers, system engineers, nuclear safety supervision personnel can quickly and conveniently check the expected overdue and actual overdue conditions of preventive maintenance work, respond in the first time, ensure that projects are executed according to time, and ensure the safe and stable operation of the unit.
According to the embodiment of the invention, the first items to be monitored are effectively classified according to various different preset conditions, and the classified first items are subjected to the exceeding degree determination in different exceeding determining modes respectively, so that the time limit of preventive maintenance items of different types can be monitored accurately, a large amount of working time and manpower resources are saved, the exceeding risk of the preventive maintenance items of the domestic nuclear power plant is obviously reduced, the periodic test meets the requirements of relevant national regulations, and the safe and stable operation of the nuclear power plant is ensured. In addition, the embodiment of the disclosure reduces the conditions of unexpected pre-maintenance overdue, periodical test overdue and the like caused by the problems of inaccurate deadline calculation, non-uniform rules and the like, is convenient for carrying out unified management on each power plant, and is beneficial to the safe and stable operation of the nuclear power plant.
In a possible implementation manner, the controller may pre-store a plurality of different preset conditions, the different preset timeout conditions may correspond to the mailbox addresses of one or more workers, and the mailbox addresses corresponding to each preset timeout condition may be completely different or partially the same. When the controller judges that the degree of the overdue meets one preset overdue condition of the plurality of preset conditions, the reminding mail can be sent to the mailbox of the worker corresponding to the preset overdue condition, and therefore people of different groups can be reminded according to the severity of the overdue. For example, the preset overrun condition a is less than 12.5%, the preset overrun condition b is between 12.5% and 20%, the preset overrun condition c is between 20% and 25%, and the preset overrun condition d is greater than 25%. And if the determined overdue degree is 16%, the controller generates a reminding mail and sends the reminding mail to one or more mailbox addresses corresponding to the preset overdue condition b.
In one possible implementation, step 101 may include: if the first item does not replace other items and the first item is executed for the first time, determining the degree of expiration of the first item according to the current system date, the expiration date of the first item and the execution frequency of the first item.
In the embodiment of the present disclosure, if there is an execution content of a first item that can override an execution content of a second item, and an execution frequency of the first item is less than an execution frequency of the second item, the first item may be executed instead of the second item, i.e., the execution of the second item is stopped, and the first item is executed.
For example, the first item may set corresponding tag information, where the tag information may be at least used to record information of whether the first item replaces other items, and if the first item replaces other items, the tag information may record information of other items replaced by the first item, for example, a name, an execution frequency, an expiration date, and the like of the other items replaced by the first item, and the controller may obtain the tag information of the first item and determine whether the first item replaces other items according to the tag information.
If the controller determines that the first item does not replace other items and the first item is executed for the first time, the expiration degree of the first item can be determined according to the current system date, the expiration date of the first item and the execution frequency of the first item. For example, it can be according to the formula U1＝(TS-Td 1) Nx100% determining the degree of overrun U of the first item1Wherein T isSFor the current system date, Td 1Is the expiration date of the first item and N is the frequency of execution of the first item.
In one possible implementation, step 101 may include: if the first item only replaces a second item and the second item is executed for the first time, determining an extent of expiration of the first item based on a current system date, an expiration date of the second item, and a frequency of execution of the second item. In the embodiment of the present disclosure, if a first item replaces a second item, the degree of the expiration should be determined according to the execution frequency of the replaced second item, and the degree of the expiration is calculated by using the higher execution frequency of the second item, so that the degree of the expiration can be determined more strictly, and the risk of the expiration of the first item is further reduced. For example, it can be according to the formula U1＝(TS-Td 2) Mx 100% determining the degree of overrun U of the first item1Wherein T isSFor the current system date, Td 2M is the execution frequency of the second item.
In one possible implementation manner, step 101 may further include: if the first item only replaces a second item and the second item replaced by the first item is not executed for the first time, determining the degree of expiration of the first item according to the current system date, the expiration date of the second item, the last execution completion date of the second item, and the execution frequency of the second item.
For example, it can be according to the formula U1＝MAX{K1|(TS-Td 2)/M×100％，K2|(TS-Td 0) /(M-1). times.100% }, the degree of expiration U of the first item is determined1Wherein, TSFor the current system date, Td 2Is the expiration date, T, of the second itemd 0The last execution completion date of the second item, M is the execution frequency of the second item, K1For cutting relative to a second itemDegree of expiry date-determined expiry, K2The degree of overrun determined relative to the last executed date of the second item.
In this way, when confirming the term overdue degree, the disclosed embodiment effectively reduces the occurrence probability of inaccurate overdue determination caused by the substitution relation among the terms in consideration of the substitution relation among the terms, whether the substituted term is executed for the first time, and the like.
In one possible implementation, if the first item replaces the plurality of items, an item with the highest execution frequency in the plurality of items may be selected as the target item, and if the target item is executed for the first time, the expiration degree of the first item may be determined according to the current system date, the expiration date of the target item, and the execution frequency of the target item.
In one possible implementation, if the first item replaces the plurality of items, an item with the highest execution frequency in the plurality of items may be selected as the target item, and if the target item is not executed for the first time, the expiration degree of the first item may be determined according to the current system date, the expiration date of the target item, the last execution completion date of the target item, and the execution frequency of the target item.
In one possible implementation, step 101 may include: if the first item is successfully executed last time and the deadline date and the execution frequency of the first item are not adjusted under the condition that the first item does not replace other items, determining the overdue degree of the first item according to the current system date, the deadline date of the first item, the last execution finish date of the first item and the execution frequency of the first item.
For example, it can be according to the formula U1＝MAX{K3|(TS-Td 1)/N×100％，K4|(TS-Td 3) /(N-1). times.100% }, the degree of expiration U of the first item is determined1Wherein, TSFor the current system date, Td 1Is the expiration date of the first item, Td 3The last execution completion date of the first item, N the execution frequency of the first item, K3For the degree of expiry determined relative to the expiry date of the first item, K4The degree of overrun determined relative to the last executed completion date of the first item. Make U1Get K3And K4The maximum value can be obtained, and the term exceeding degree of the project can be monitored more strictly.
In one possible implementation, step 101 may include: if the deadline date and the execution frequency of the first project are not adjusted and the work order task completion status of the first project executed last time is abnormal, determining the degree of expiration of the first project according to the current system date, the deadline date of the first project, the execution completion date of the copy work order of the first project and the execution frequency of the first project.
In the embodiment of the present disclosure, generally speaking, if the completion status of the work order task is abnormal and the project is successfully executed, it indicates that there is a situation that the work order task is copied and the copy work order is executed, and therefore, the completion date of the copy work order needs to be adopted to further ensure the accuracy of calculating the expiration degree of the project of the type of the present embodiment.
For example, it can be according to the formula U1＝MAX{K3|(TS-Td 1)/N×100％，K5|(TS-Td 4) /(N-1). times.100% }, the degree of expiration U of the first item is determined1Wherein, TSFor the current system date, Td 1Is the expiration date of the first item, Td 4The date of the last execution of the copy work order of the first project, N is the frequency of the first project, K3For the degree of expiry determined relative to the expiry date of the first item, K5An extent of expiration is determined relative to a date of completion of execution of the copy work order when the first project was last executed.
In one possible implementation, step 101 may include: if the first item is executed last time and the deadline and the execution frequency of the first item are adjusted under the condition that the first item does not replace other items, determining the degree of expiration of the first item according to the current system date, the adjusted deadline of the first item and the adjusted execution frequency of the first item.
In the embodiment of the present disclosure, if the execution frequency and the expiration date of the item are adjusted after the execution of the item is completed, the next expiration of the item should be determined according to the adjusted execution frequency and the adjusted expiration date. In this way, when confirming the term expiration degree, the embodiment of the disclosure considers the factor of whether the term is adjusted, and effectively reduces the occurrence probability of inaccurate expiration determination caused by the adjustment of the term.
For example, it can be according to the formula U1＝(TS-Td 5) Per M100%, determining the degree of overrun U of the first item1Wherein, TSFor the current system date, Td 5The adjusted expiration date for the first item, and M is the adjusted execution frequency for the first item.
In one possible implementation, step 101 may include: and under the condition that the first item does not replace other items, if the last execution of the first item is cancelled and the first item is not equivalent by other works, determining the degree of expiration of the first item according to the current system date, the expiration date of the first item and the execution frequency of the first item.
For example, it can be according to the formula U1＝(TS-Td 1) Nx100% determining the degree of overrun U of the first item1Wherein T isSFor the current system date, Td 1Is the expiration date of the first item and N is the frequency of execution of the first item.
In one possible implementation, step 101 may include: under the condition that the first project does not replace other projects, if the last execution of the first project is cancelled and the first project is equivalent by other works, determining the degree of expiration of the first project according to the current system date, the expiration date of the first project, the execution finishing date of the works equivalent to the first project and the execution frequency of the first project.
For example, it can be according to the formula U1＝MAX{K3|(TS-Td 1)/N×100％，K6|(TS-Tb) /(N-1). times.100% } determines the degree of expiration U of the first item1Wherein, TSFor the current system date, Td 1Is the expiration date of the first item, N is the execution frequency of the first item, TbFor the completion date of the job equivalent to the first project, K3For the degree of expiry determined relative to the expiry date of the first item, K6The degree of overrun determined for the date of completion of execution of the equivalent work last time with respect to the first project.
