In order to accurately evaluate and improve device performance, overall equipment efficiency (OEE) has become a core indicator for measuring the comprehensive performance of equipment, and plays a crucial role in production optimization, capacity planning, and cost control.

[0003] At present, the industry generally uses planned production tact time as a benchmark to calculate device effective running time, and then obtains the OEE value. This calculation method facilitates standardized management of enterprises to some extent, and provides a unified reference standard for production management.

[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] Currently, the industry generally uses planned production cycle time as a benchmark to calculate equipment effective operating time, thereby deriving the OEE value. This calculation method facilitates standardized management for enterprises to a certain extent, providing a unified reference standard for production management. However, in actual production applications, the production site is often affected by various factors, leading to deviations between the actual and planned equipment operating times. Moreover, the planned time model lacks effective consideration of the correlation between production cycle time deviation and equipment status, resulting in a serious disconnect between theoretical and actual capacity. This leads to poor accuracy in calculating the effective operating time of equipment, thus affecting the reliability analysis of overall equipment efficiency.

[0065] Based on this, this application proposes the following technical solution, as detailed below:

[0066] In one embodiment, such as Figure 1 As shown, Figure 1 This is a flowchart illustrating a method for calculating the effective operating time of a device, provided in an embodiment of this application. The method includes the following specific steps:

[0067] S110: Obtain the planned processing data of the target station in the current running cycle, and determine the operation type of the target station according to the planned processing data; wherein the current running cycle is formed by a plurality of production beats, each production beat is composed of an actual beat and a beat interval; the operation type includes single shift and multi-shift.

[0068] In this step, when calculating the effective time of the computing device, the computer device can first obtain the planned processing data of the target station in the current running cycle, wherein the current running cycle is formed by a plurality of production beats, each production beat is composed of an actual beat and a beat interval, and then the operation type of the target station can be determined according to the planned processing data, so as to associate the calculation process of the effective time with the device state, so as to evaluate the device running in line with the actual production situation, and avoid the disconnection between the calculation result and the actual production capacity due to the uniform adoption of a single standard.

[0069] Among them, the production beat refers to the minimum time unit of the station in a standard running cycle in the industrial Internet of Things big data platform production line, that is, the time framework of a complete production action, which can be used to measure the station rhythm. The actual beat refers to the time that the station is actually used for processing products in a production beat, that is, the time period during which the device is in the "running / working" state; the beat interval refers to the non-processing time between two actual beats, that is, the time period during which the device is in the "waiting / stop" state. Therefore, in the station, a plurality of production beats can constitute a running cycle, and the running cycle of the present application can be in units of days.

[0070] It should be noted that the actual beat and the beat interval contained in each production beat of the target station in the current running cycle all belong to the actual running data generated by the device of the target station in the production process, and each running cycle is provided with corresponding planned processing data in advance, including planned shift time, planned handover time and planned rest time, for describing the running arrangement of the device in the ideal state.

[0071] Specifically, after the computer device obtains the planned processing data of the target station, it can first determine whether there is a planned handover time in the planned processing data, and then determine whether the operation type of the target station is single shift or multi-shift. Among them, single shift means that the station device has only one complete processing period in a running cycle, and the operation is completed in a fixed shift; and multi-shift means that the station has two or more processing periods in the same running cycle, and each processing period is provided with a handover time, and the operation needs to be completed by multiple shifts. Therefore, when there is no planned handover time in the planned processing data, it means that the operation type of the target station is single shift, otherwise, it means that the operation type of the target station is multi-shift.

[0072] It can be understood that since it is difficult to associate the production rhythm deviation with the equipment state by the planned processing data, determining the operation type is an important prerequisite for subsequent accurate calculation of actual processing data, therefore, based on the planned processing data, the actual data of the production rhythm and the judgment of the operation type of the station can be combined, the calculation process of the effective time is closely associated with the equipment running state, so that the actual running state of the equipment in the complex production environment can be more truly restored.

[0073] In S120, the actual start rhythm and the actual end rhythm of the current running period are determined from each actual rhythm based on each rhythm interval by using the shift calculation rule corresponding to the operation type, and the actual shift time is determined according to the actual start rhythm and the actual end rhythm.

[0074] In this step, after determining the operation type of the target station in step S110, the computer device can use the shift calculation rule corresponding to the operation type to determine the actual start rhythm and the actual end rhythm of the current running period from each actual rhythm based on each rhythm interval, and then determine the actual shift time, so that the actual rhythm can be used to overcome the problem of disconnection between the planned time and the actual capacity.

[0075] The actual start rhythm refers to the first time when the station performs effective processing action in a running period, indicating the starting point of the equipment formally put into production in the current shift; the actual end rhythm refers to the last time when the station completes effective processing action in a running period, indicating the end point of the production task of the equipment in the current shift. Therefore, the actual shift time refers to the production duration between the actual start rhythm and the actual end rhythm.

[0076] Specifically, since the equipment of different operation types of stations shows obvious rhythm and behavior differences in actual operation process, if a unified shift calculation rule is used, the computer device will be prone to deviation in rhythm and time period identification, therefore, the computer device can select the shift calculation rule suitable for the operation type of the target station, analyze the production rhythm sequence in the current running period, and identify the actual start rhythm when the equipment truly starts processing operation and the actual end rhythm when the last effective processing is completed from each actual rhythm based on the rhythm interval information between each actual rhythm, and then calculate the actual shift time of the target station in the current running period.

[0077] More specifically, when calculating the actual shift time, the computer device can first determine the start time of the actual start rhythm and the end time of the actual end rhythm, and then subtract the start time from the end time to obtain the actual shift time of the target station in the current running period.

[0078] S130: filtering actual rest beats in the current running cycle from the production beats based on the planned rest time in the planned processing data and the equipment failure signal, and determining the actual rest time according to the actual rest beats.

[0079] In this step, after the actual shift time is calculated through step S120, the computer device can further filter actual rest beats in the current running cycle from the production beats based on the planned rest time in the planned processing data and the equipment failure signal, and then determine the actual rest time, so as to avoid the impact of the rest time caused by shutdown on the equipment operation.

[0080] The planned rest time refers to a non-processing time period preset in a running cycle for the safety of equipment operation, and the equipment failure signal refers to the failure state information collected and reported in real time by the industrial control system or the equipment itself, and is used to indicate the non-planned shutdown of the equipment due to sudden or accumulated problems during operation.

[0081] Specifically, since the non-processing time of the rest time and the equipment failure is much longer than the production beat duration in the normal production process, the production beat duration corresponding to the two is similar, so the application can filter the actual rest beats in the current running cycle from the production beats based on the planned rest time and the equipment failure signal, so as to avoid regarding the production beat corresponding to the equipment failure shutdown as the actual rest beat of the station, and then mislead the calculation of the actual rest time.

[0082] More specifically, when calculating the actual rest time, the computer device can first determine the start time and the end time of the actual rest beat, and then subtract the start time from the end time, so as to obtain the actual rest time of the target station in the current running cycle for resting to recover the performance.

[0083] S140: when the job type is multi-shift, filtering actual handover beats in the current running cycle from the production beats based on the planned handover time in the planned processing data and the production beat duration of each production beat, and determining the actual handover time according to the actual handover beats.

[0084] In this step, since the multi-shift job type also needs to consider the impact of the handover time, when the target station is in multi-shift operation, the computer device also needs to filter actual handover beats in the current running cycle from the production beats based on the planned handover time in the planned processing data and the production beat duration of each production beat, and then determine the actual handover time, so as to further improve the accuracy of the calculation of the effective time of the equipment operation.

[0085] Specifically, the computer device can analyze all production beats in the current running cycle one by one based on the preset planned handover time in the planned processing data and the production beat length of each production beat, and screen out production beats in the handover process, non-processing state but not in the rest state, and mark them as actual handover beats. The actual handover beat usually shows a short non-processing period caused by personnel replacement, equipment state switching, task counting and transfer, environment adjustment, etc. Although it is not a normal processing process, it is a necessary process for multi-shift operation.

[0086] More specifically, when calculating the actual handover time of multi-shift operation, the computer device can first determine the start time and the end time of the actual handover beat, and then subtract the start time from the end time to obtain the actual handover time of the target work position in the current running cycle.

[0087] S150: Calculate the actual shift time, the actual rest time and the actual handover time according to the job type to obtain the device running effective time of the target work position in the current running cycle.

[0088] In this step, after calculating each time period in the current running cycle through steps S120-S140, the computer device can calculate the actual shift time, the actual rest time and the actual handover time according to the job type to obtain the device running effective time of the target work position in the current running cycle, which provides high-credibility analysis data for the overall device efficiency.

[0089] For example, when the job type is single shift, the work position does not need to perform job handover, so there is no actual handover time, and the computer device can directly calculate the device running effective time through the actual shift time and the actual rest time; when the job type is multi-shift, the work position needs to perform job handover, so there is actual handover time, and the computer device can calculate the device running effective time through the actual shift time, the actual rest time and the actual handover time.

[0090] In the above embodiments, when the computing device runs the effective time, the planned processing data of the target station in the current running cycle can be obtained first, where the current running cycle is formed by a plurality of production beats, and each production beat is composed of an actual beat and a beat interval, and then the work type of the target station can be determined according to the planned processing data, so as to associate the calculation process of the effective time with the device state, that is, the shift calculation rule corresponding to the work type is adopted, the actual start beat and the actual end beat of the current running cycle are determined from each actual beat based on each beat interval, and then the actual shift time is determined, so that the actual beat can be used to overcome the problem that the planned time is disconnected from the actual production capacity. In addition, the actual rest beat of the current running cycle can also be obtained by screening from each production beat based on the planned rest time in the planned processing data and the device fault signal, and then the actual rest time is determined, so as to avoid the influence of the rest time caused by shutdown on the device running. In order to further improve the accuracy of the effective time of the device running, the influence of the handover time of the multi-shift work type also needs to be considered, where the actual handover beat of the current running cycle is obtained by screening from each production beat based on the planned handover time in the planned processing data and the length of each production beat, and then the actual handover time is determined. Finally, based on the determined time periods, the high-precision effective time of the device running can be calculated, which provides high-credibility analysis data for the overall device efficiency.

[0091] In one embodiment, the process of adopting the shift calculation rule corresponding to the work type to determine the actual start beat and the actual end beat of the current running cycle from each actual beat based on each beat interval in step S120 can include:

[0092] S1211: When the work type is single shift, the first prediction period is divided according to the planned shift time in the planned processing data, and the beat interval in the first prediction period is threshold compared from the positive sequence and the reverse sequence respectively.

[0093] S1212: When three continuous beat intervals are less than the first preset time length in the positive sequence, the actual beat corresponding to the first beat interval in the three continuous beat intervals is taken as the actual start beat of the current running cycle.

[0094] S1213: When three continuous beat intervals are less than the first preset time length in the reverse sequence, the actual beat corresponding to the last beat interval in the three continuous beat intervals is taken as the actual end beat of the current running cycle.

[0095] In the embodiment, when the job type is single shift, the computer device can divide a first prediction period according to the planned shift time in the planned processing data, and respectively perform threshold comparison on the tact intervals in the first prediction period from the forward sequence and the reverse sequence, and then can determine the actual start tact and the actual end tact of the current running period from the actual tacts according to the comparison results, as the calculation basis of the actual shift time.

[0096] Specifically, as shown in Figure 2 , Figure 2 a single shift job type relationship between the planned shift and the actual shift provided by the embodiment of the application; from Figure 2 It can be seen that during the single shift operation of the workstation device, there is some deviation between the planned shift time and the actual shift time. Therefore, in order to improve the accuracy of the effective operation time of the device, the computer device can divide a first prediction period according to the planned shift time in the planned processing data, the range of the first prediction time needs to cover all possible deviation sizes of the planned shift time, and then can respectively perform threshold comparison on the tact intervals in the first prediction period from the forward sequence and the reverse sequence, so that when there are three continuous tact intervals less than the first preset time length in the forward sequence, the actual tact corresponding to the first tact interval of the three continuous tact intervals is taken as the actual start tact of the current running period, and when there are three continuous tact intervals less than the first preset time length in the reverse sequence, the actual tact corresponding to the last tact interval of the three continuous tact intervals is taken as the actual end tact of the current running period.

[0097] For example, the starting time of the first prediction period can be two hours before the starting time of the planned shift time, and the ending time can be two hours after the ending time of the planned shift time; the first preset time length can be 0.5 times of the average actual tact length. Through the forward and reverse threshold comparison, the starting time and the ending time of the actual start tact are 2025-01-01 07:35:59 and 2025-01-01 07:36:58 respectively, and the starting time and the ending time of the actual end tact are 2025-01-01 18:49:58 and 2025-01-01 18:50:56 respectively, based on which, the actual shift time is the time period between 2025-01-01 07:35:59 and 2025-01-01 18:50:56.

[0098] Schematically, as shown in Figure 3 and Figure 4 , Figure 3 a single shift job type actual shift start time calculation schematic diagram provided by the embodiment of the application; Figure 4 a single shift job type actual shift end time calculation schematic diagram provided by the embodiment of the application;Figure 3 In the positive order, when the first time interval is greater than 0.5 times of the average actual tact length, it is indicated that the first actual tact corresponding to the time interval is the first tact in the trial run in the current running period, and the tact intervals between the subsequent three actual tacts after the actual tact all satisfy the condition of being less than 0.5 times of the average actual tact length, which indicates that the work station device has formally carried out processing and production from the second actual tact, and thus the first actual tact in the three continuous actual tacts satisfying the condition is the actual start tact. Similarly, Figure 4 In the reverse order, when the tact intervals between the three continuous actual tacts all satisfy the condition, the last actual tact among them can be taken as the actual end tact, marking the end of the work station operation in the current running period.

[0099] In an embodiment, the process of determining the actual start tact and the actual end tact of the current running period from the actual tacts based on the tact intervals in step S120 adopts the shift calculation rule corresponding to the operation type, and further includes:

[0100] S1221: When the operation type is multi-shift, a second prediction period is determined according to the current running period; the second prediction period spans the current running period and the last running period.

[0101] S1222: The tact intervals in the second prediction period are compared in the positive order to obtain a comparison result.

[0102] S1223: If there are two continuous tact intervals in the comparison result, the previous tact interval is greater than a second preset length and the next tact interval is greater than a first preset length, the actual tact corresponding to the next tact interval is taken as the actual start tact of the current running period, and the actual tact corresponding to the previous tact interval is taken as the actual end tact of the current running period.

[0103] In the embodiment, when the operation type is multi-shift, the computer device can determine a second prediction period according to the current running period, compare the tact intervals in the second prediction period in the positive order to obtain a comparison result, and then determine the actual start tact and the actual end tact of the current running period from the actual tacts according to the comparison result, as the basis for calculating the actual shift time.

[0104] It can be understood that the target work station has consistent running rhythm in the two continuous running periods, and thus the actual end tact of the previous running period can be regarded as the actual end tact of the current running period. There is a tact interval between the last actual tact of the previous running period and the first actual tact of the current running period, which spans the two running periods and is much greater than the tact interval during the work station operation.

[0105] Specifically, as Figure 5 shown, Figure 5 a schematic diagram of a relationship between a planned shift and an actual shift of a multi-shift operation type provided for an embodiment of the present application; from Figure 5 It can be seen that, in the process of multi-shift operation of the station equipment, there are also some deviations between the planned shift time and the actual shift time. Therefore, in order to improve the accuracy of the effective operation time of the equipment, the computer equipment can divide a second prediction period according to the current operation period, the second prediction period spanning the current operation period and the previous operation period, and then respectively compare the beat intervals in the second prediction period with a threshold value in a forward direction, if there are two beat intervals in the comparison result, the previous beat interval is greater than a second preset time length and the next beat interval is greater than a first preset time length, the actual beat corresponding to the next beat interval is taken as the actual start beat of the current operation period, and the actual beat corresponding to the previous beat interval, i.e. the actual end beat of the previous operation period, is taken as the actual end beat of the current operation period. It should be noted that, since the beat interval corresponding to the second preset time length spans two operation periods, and the beat interval corresponding to the first preset time length is the beat interval during normal operation of the station, the second preset time length needs to be much greater than the first preset time length.

[0106] For example, the time period between the previous operation period 12:00 and the current operation period 12:00 of the second prediction period; the first preset time length can be 0.5 times the average actual beat length, and the second preset time length can be 4 hours. Through the forward threshold value comparison, two beat intervals that meet the condition are obtained, in which the start time and the end time of the actual start beat corresponding to the next beat interval are 2025-01-02 07:45:59 and 2025-01-02 07:46:58 respectively, and the start time and the end time of the actual end beat corresponding to the previous beat interval are 2025-01-01 18:49:58 and 2025-01-01 18:50:56 respectively. Based on this, the actual shift time is the time period between 2025-01-02 07:45:59 and 2025-01-02 18:50:56.

[0107] Schematically, as Figure 6 shown, Figure 6 a schematic diagram of the calculation of the actual shift time of the multi-shift operation type provided for an embodiment of the present application; Figure 6In the embodiment, the threshold comparison of the beat intervals in the second prediction period in the normal order can obtain that the first beat interval is greater than 4 hours, and the subsequent several beat intervals are all less than 0.5 times of the average actual beat length, which indicates that the actual beat before the first beat interval is the last actual beat of the last operation cycle and can be regarded as the actual end beat of the current operation cycle, and the actual beat after the first beat interval is the first actual beat of the current operation cycle and is the actual start beat of the current operation cycle, and then the actual shift time of the multi-shift operation can be determined according to the start time of the actual start beat and the end time of the actual end beat.

[0108] In one embodiment, the determination process of the actual shift time in step S120 can further include:

[0109] S1224: When the operation type is multi-shift, if there is no two continuous beat intervals in the comparison result, the previous beat interval is greater than the second preset length, and the next beat interval is greater than the first preset length, the third prediction period is determined according to the planned shift time in the planned processing data.

[0110] S1225: The production beat with an actual beat length greater than the third preset length is selected from the third prediction period to form a shift beat list.

[0111] S1226: If the shift beat list is empty, the start time of the planned shift time is taken as the actual shift start time, and the end time is taken as the actual shift end time.

[0112] S1227: If the shift beat list is one production beat, the end time of the beat interval in the production beat is taken as the actual shift start time, and the start time is taken as the actual shift end time.

[0113] S1228: If the shift beat list is a plurality of production beats, the end time of the beat interval in the production beat closest to the planned shift time is taken as the actual shift start time, and the start time is taken as the actual shift end time.

[0114] S1229: The actual shift time is calculated according to the actual shift start time and the actual shift end time.

[0115] In the embodiment, if the target station is multi-shift operation, and there is no two continuous beat intervals in the second prediction period, that is, the previous beat interval is greater than the second preset length, and the next beat interval is greater than the first preset length, the computer device can determine the third prediction period according to the planned shift time in the planned processing data, then the production beat with a production beat length greater than the third preset length can be selected from the third prediction period to form a shift beat list, and then the final actual shift time can be determined according to the number of beats in the shift beat list.

[0116] Specifically, the third prediction period of the present application can be one hour forward and backward from the starting time of the planned shift time; in addition, the third preset duration can refer to a duration of five minutes more than the average value of the production rhythm in the normal operation process of the station. The production rhythm greater than the third preset duration in the third prediction period can be regarded as a rhythm conforming to the shift time calculation, at this time the computer device can form a shift rhythm list according to all the qualified production rhythms, determine the most suitable actual shift end time and actual shift start time according to the number of rhythms in the shift rhythm list, and then calculate the actual shift time.

[0117] More specifically, when the shift rhythm list is empty, it means that there is no production rhythm conforming to the shift time calculation in the third prediction period, at this time the computer device can take the starting time of the planned shift time as the actual shift start time and the end time as the actual shift end time. When the shift rhythm list is one production rhythm, it means that the rhythm interval in the production rhythm connects the actual rhythms of two running cycles, at this time the computer device can take the end time of the rhythm interval in the production rhythm as the actual shift start time and the start time as the actual shift end time; when the shift rhythm list is multiple production rhythms, it means that there are production rhythms with relatively long rhythm intervals due to factors such as operation handover during the operation of the station, at this time the computer device can take the end time of the rhythm interval in the production rhythm closest to the planned shift time as the actual shift start time and the start time as the actual shift end time.

[0118] In one embodiment, the process of filtering the actual rest rhythm of the current running cycle from each production rhythm based on the planned rest time in the planned processing data and the equipment failure signal in step S130 can include:

[0119] S131: defining a fourth prediction period according to the planned rest time in the planned processing data, and determining whether there is equipment failure in the fourth prediction period through the equipment failure signal.

[0120] S132: If not, filter out the production rhythm whose duration is greater than the fourth preset duration from the fourth prediction period to form a rest rhythm list.

[0121] S133: If the rest rhythm list is empty or there is equipment failure, generate the actual rest rhythm of the current running cycle according to the planned rest time.

[0122] S134: If the rest rhythm list is one production rhythm, take the production rhythm as the actual rest rhythm of the current running cycle.

[0123] S135: If the rest beat list is multiple production beats, the production beat closest to the planned rest time is taken as the actual rest beat of the current running cycle.

[0124] In this embodiment, when determining the actual rest beat of the previous running cycle, the computer device can delimit a fourth prediction period according to the planned rest time in the planned processing data, and screen out production beats with a production beat duration greater than a fourth preset duration from the fourth prediction period to form a rest beat list, and then determine the final actual rest beat according to the number of beats in the rest beat list and the device fault signal.

[0125] Specifically, if the device fault signal appears in the fourth prediction period, it indicates that there is a production beat corresponding to the fault in the fourth prediction period. To avoid the influence of the device fault on the determination of the actual rest beat, the computer device can construct the actual rest beat of the current running cycle according to the start time and the end time of the planned rest time. If there is no device fault signal in the fourth prediction period, the computer device can screen out production beats with a production beat duration greater than a fourth preset duration from the fourth prediction period to form a rest beat list, and then determine the actual rest beat according to the number of beats in the rest beat list, so as to take the start time of the actual rest beat as the start time of the actual rest time, and take the end time as the end time of the actual rest time. For example, when the rest beat list is empty, it indicates that there is no production beat in the fourth prediction period that meets the rest time calculation. At this time, the computer device can construct the actual rest beat according to the start time and the end time of the planned rest time. When the rest beat list is one production beat, it indicates that the production beat meets the rest time calculation and is not disturbed by other beats. At this time, the computer device can take the production beat as the actual rest beat of the current running cycle. When the rest beat list is multiple production beats, it indicates that there are multiple production beats close to the rest time during the work station operation due to factors such as work handover. At this time, the computer device can take the production beat closest to the planned rest time as the actual rest beat of the current running cycle.

[0126] For example, as shown in Figure 7 , Fig. 1 is a schematic diagram of the calculation of the actual rest time during the running of the work station provided by an embodiment of the present application; Figure 7 Figure 7 ​In the embodiment, the fourth prediction period can refer to a period from 0.5 times the planned rest time before the start time of the planned rest time to 0.5 times the planned rest time after the end time, and the fourth preset time length can be 0.5 times the planned rest time. During the work station operation, there is a start time and an end time of the actual rest beat meeting the rest condition, which are 2025-01-01 11:56:42 and 2025-01-01 12:45:11 respectively, which indicates that the start time of the actual rest time of the work station is 2025-01-01 11:56:42 and the end time is 2025-01-01 12:45:11.

[0127] In an embodiment, the process of screening the actual handover beat of the current running cycle from the production beats based on the planned handover time in the planned processing data and the actual beat time length of each production beat in step S140 can include:

[0128] S141: determining a fifth prediction period according to the planned handover time in the planned processing data, and screening the production beats with a production beat time length greater than a fifth preset time length from the fifth prediction period to form a handover beat list.

[0129] S142: if the handover beat list is empty, generating the actual handover beat of the current running cycle according to the planned handover time.

[0130] S143: if the handover beat list is one production beat, taking the production beat as the actual handover beat of the current running cycle.

[0131] S144: if the handover beat list is multiple production beats, taking the production beat closest to the planned handover time as the actual handover beat of the current running cycle.

[0132] In the embodiment, when determining the actual handover beat of the work station multi-shift operation in the current running cycle, the computer device can determine a fifth prediction period according to the planned handover time in the planned processing data, screen the production beats with a production beat time length greater than a fifth preset time length from the fifth prediction period to form a handover beat list, and then determine the final actual rest beat according to the number of beats in the handover beat list and the device fault signal.

[0133] Specifically, the computer device can filter out the production rhythm whose duration is greater than the fifth preset duration from the fifth prediction period to form a handover rhythm list, and then determine the actual handover rhythm according to the number of rhythms in the handover rhythm list, take the start time of the actual handover rhythm as the start time of the actual handover time, and take the end time as the end time of the actual handover time. For example, when the handover rhythm list is empty, it means that there is no production rhythm in the fifth prediction period that meets the handover time calculation, at this time the computer device can construct the actual handover rhythm according to the start time and the end time of the planned handover time. When the handover rhythm list is one production rhythm, it means that the production rhythm meets the handover time calculation and there is no interference of other rhythms, at this time the computer device can take the production rhythm as the actual handover rhythm of the current running period; when the handover rhythm list is multiple production rhythms, it means that there are other factors during the work station operation that cause multiple production rhythms to be close to the handover time, at this time the computer device can take the production rhythm closest to the planned handover time as the actual handover rhythm of the current running period.

[0134] For example, as shown in Figure 8 , Figure 8 is a schematic diagram of the calculation of the actual handover time of the multi-shift operation type provided by the embodiment of the present application; from Figure 8 It can be seen that the fifth prediction period of the present application can refer to the time period from one hour before the start time of the planned handover time to one hour after the end time, and the fifth preset duration can be 5 minutes. During the work station operation, there is an actual handover rhythm whose start time and end time meet the handover condition, which are 2025-01-01 20:33:09 and 2025-01-01 20:39:49 respectively, then it is explained that the start time of the actual handover time of the work station is 2025-01-01 20:33:09, and the end time is 2025-01-01 20:39:49.

[0135] In one embodiment, the process of calculating the actual shift time, the actual rest time and the actual handover time according to the operation type in step S150 to obtain the device running effective time of the target work station in the current running period can include:

[0136] S151: When the operation type is single shift, the actual shift time is subtracted from the actual rest time to obtain the device running effective time of the target work station in the current running period.

[0137] S152: When the operation type is multi-shift, the actual shift time is subtracted from the actual rest time and the actual handover time to obtain the device running effective time of the target work station in the current running period.

[0138] In this embodiment, the work type of the target work station can include single shift and multi-shift. Different from single shift work, there is an actual handover time during multi-shift work. Therefore, when the work type is single shift, the computer device can obtain the device operation effective time of the target work station in the current operation period by subtracting the actual rest time from the actual shift time; when the work type is multi-shift, the computer device can obtain the device operation effective time of the target work station in the current operation period by subtracting the actual rest time and the actual communication time from the actual shift time.
