[0047] Figure 2 is a block diagram of a nuclear power maintenance time estimation device according to an exemplary embodiment.

[0048] Figure 3 is a block diagram of a nuclear power maintenance time estimation device according to an exemplary embodiment. DETAILED DESCRIPTION

[0049] The application will be described in further detail below with reference to the drawings and specific embodiments.

[0050] Figure 1 is a flow chart of a nuclear power maintenance duration estimation method according to an exemplary embodiment. The method can be executed by a terminal device, where the terminal device can be a server, a desktop computer, a notebook computer, a tablet computer, etc. The terminal device can also be, for example, a user equipment, a vehicle-mounted device, or a wearable device, etc. The type of the terminal device is not limited in the embodiments of the present disclosure. As shown in Figure 1 the method includes:

[0051] Step 10, determining available maintenance personnel for a target device currently in need of maintenance.

[0052] For example, step 10 can include:

[0053] Step 100, obtaining the level of the target device;

[0054] Step 101, obtaining the level of each maintenance personnel, the number of work tickets currently held by the maintenance personnel, and downtime information;

[0055] Step 102, for each maintenance personnel, if the level of the maintenance personnel is greater than or equal to the level of the target device, and the number of work tickets held by the maintenance personnel is less than a preset number (where the preset number can be determined according to historical experience), and the maintenance personnel has no downtime information (downtime information can represent an information identifier indicating that the maintenance personnel is in a downtime state due to a violation or leave, etc.), the maintenance personnel is determined as an available maintenance personnel. Correspondingly, if the number of work tickets held by the maintenance personnel is greater than or equal to the preset number, or the maintenance personnel has downtime information, the maintenance personnel is unavailable.

[0056] In this way, available personnel can be selected according to the level and working status of the maintenance personnel.

[0057] Step 11, in the case where the available maintenance personnel are multiple, determining, for each available maintenance personnel, an estimated duration of the maintenance personnel, where the estimated duration is used to represent the estimated duration required by the maintenance personnel to maintain the target device.

[0058] For example, step 11 can include: Step 110, for each available maintenance personnel, summing the maintenance duration of the maintenance personnel and the waiting duration as the estimated duration of the maintenance personnel. Wherein, for each available maintenance personnel, the historical average maintenance duration of the maintenance personnel can be used as the maintenance duration of the employee, and the waiting duration of the maintenance personnel can be determined according to the current time and the time at which the maintenance personnel is expected to complete the maintenance work in the system when the maintenance personnel is currently maintaining.

[0059] Step 12, taking the estimated time length meeting the preset condition as the time length required for repairing the target device, and assigning the repairer whose estimated time length meets the preset condition as the person responsible for repairing the target device.

[0060] For example, in step 12, after obtaining the estimated time lengths of the repairers available, the repairer with the shortest estimated time length can be taken as the person responsible for repairing the target device, and the shortest estimated time length can be taken as the time length required for repairing the target device.

[0061] According to steps 10-12, the repair time lengths of the devices in the nuclear power plant can be estimated, and the estimated duration of the entire overhaul and each sub-project of the overhaul can be determined.

[0062] The nuclear power repair time length estimation method provided by the present disclosure determines the repairers available according to the target device currently in need of repair, determines the estimated time length required for each available repairer to repair the target device, takes the estimated time length meeting the preset condition as the time length required for repairing the target device, and assigns the repairer whose estimated time length meets the preset condition as the person responsible for repairing the target device. In this way, the suitable repairer can be assigned according to the actual situation of the repairer, the completion time of a single repair work and the completion time of a large number of parallel works can be accurately evaluated, and the accurate parallel window duration of the refueling overhaul can be obtained.

[0063] In a possible implementation, step 110 includes:

[0064] Step 1100, determining the type of the target device.

[0065] Step 1101, determining the ratio between the average time length required for each available repairer to repair the target device (for example, the ratio between the total repair time length of the repairer for the target device and the repair times) and the average time length required for all repairers to repair the target device (for example, the ratio between the total repair time length of the target device and the total repair times), and taking the product of the ratio and the average time length required for all repairers to repair the target device (for example, the ratio between the total repair time length of the target device and the total repair times) as the repair time length of the repairer.

[0066] Since the maintenance personnel may not have maintained the target device itself, the historical maintenance data of the target device cannot reflect the maintenance capability of the maintenance personnel. The present disclosure starts from the type of the target device, determines the ratio between the average time length required by the maintenance personnel to maintain the type of device and the average time length required by all maintenance personnel to maintain the type of device, and indicates the level of the maintenance personnel in the overall maintenance personnel in the maintenance of the same type of device through the ratio. On this basis, the ratio can also well fit the level of the maintenance personnel in the overall maintenance personnel in the maintenance of the target device. Thus, the product of the ratio and the average time length required by all maintenance personnel to maintain the target device is taken as the maintenance time length of the maintenance personnel, which can organically connect the maintenance personnel with the target device and more accurately estimate the time length required by each maintenance personnel to maintain the target device.

[0067] In a possible implementation, step 110 further includes:

[0068] Step 1102, for each available maintenance personnel, taking the ratio between the distance between the target device and the maintenance personnel and the personnel travel speed as the time length required by the maintenance personnel to reach the target device;

[0069] In step 1102, the position information (for example, the geographic position coordinates) of the maintenance personnel can be obtained in real time, and the position information of the target device is obtained. The distance between the maintenance personnel and the target device is determined according to the position information of the maintenance personnel and the position information of the target device. The travel speed of the personnel may, for example, be the average travel speed of the maintenance personnel, or the average travel speed of the overall maintenance personnel. The ratio between the distance between the target device and the maintenance personnel and the personnel travel speed can be taken as the time length required by the maintenance personnel to reach the target device.

[0070] Step 1103, for each available maintenance personnel, in the case that the maintenance personnel is currently performing maintenance, taking the difference between the estimated time length of the device currently maintained by the maintenance personnel and the time length of the device already maintained by the maintenance personnel as the time length required by the maintenance personnel to complete the current work;

[0071] Step 1104, taking the sum of the time length required by each available maintenance personnel to reach the target device and the time length required to complete the current work as the waiting time length of the maintenance personnel.

[0072] In a possible implementation, step 1104 further includes: taking the sum of the time length required by each available maintenance personnel to reach the target device, the time length required to complete the current work, and the work preparation time length as the waiting time length of the maintenance personnel.

[0073] In this way, the disclosure can estimate the time required for a maintenance personnel to reach and start maintenance of a target device according to the location and working state of the maintenance personnel, thereby more accurately predicting the time required for the maintenance personnel to maintain the target device.

[0077] a third determination module configured to take, as the time required for the maintenance personnel to maintain the target device, an estimated time that meets a preset condition from multiple estimated times, and assign the maintenance personnel whose estimated time meets the preset condition as the personnel responsible for maintaining the target device.

[0078] In one possible implementation, the first determination module comprises:

[0079] a first acquisition module configured to acquire the level of the target device;

[0080] a second acquisition module configured to acquire the level of each maintenance personnel, the number of work tickets currently held by the maintenance personnel, and downtime information;

[0082] In one possible implementation, the second determination module comprises:

[0084] In one possible implementation, the estimated time calculation module comprises:

[0085] a type determination module configured to determine the type of the target device;

[0086] The maintenance duration calculation module is configured to determine, for each available maintenance personnel, a ratio between an average duration required by the maintenance personnel to maintain the type of device and an average duration required by all maintenance personnel to maintain the type of device, and multiply the ratio by an average duration required by all maintenance personnel to maintain the target device to obtain a maintenance duration of the maintenance personnel.

[0087] In a possible implementation, the estimated duration calculation module further includes:

[0088] The arrival duration calculation module is configured to, for each available maintenance personnel, take a ratio between a distance between the target device and the maintenance personnel and a personnel travel speed as a duration required by the maintenance personnel to arrive at the target device.

[0089] The remaining duration calculation module is configured to, for each available maintenance personnel, in a case that the maintenance personnel is currently performing maintenance, take a difference between an estimated duration of a device currently maintained by the maintenance personnel and a duration of a device already maintained by the maintenance personnel as a duration required by the maintenance personnel to complete a current task.

[0090] The waiting duration calculation module is configured to take a sum of the duration required by each available maintenance personnel to arrive at the target device and the duration required by the maintenance personnel to complete the current task as a waiting duration of the maintenance personnel.

[0091] In a possible implementation, the waiting duration calculation module further includes: taking a sum of the duration required by each available maintenance personnel to arrive at the target device, the duration required by the maintenance personnel to complete the current task, and a task preparation duration as the waiting duration of the maintenance personnel.
