Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing systems, and more specifically, to an intelligent manufacturing MES platform. Background Art

[0002] At present, with the rapid development of industrial intelligence, intelligent manufacturing equipment and production lines have also been paid more and more attention. In the application of intelligent manufacturing, not only the output has been increased, but also the processing accuracy has been improved, so that the defective rate of products can be controlled. The accurate control of intelligent manufacturing equipment mainly benefits from the intelligent manufacturing system, which enables the manufacturing process to be controlled by a computer in a highly flexible and integrated manner, realizing information intelligent manufacturing under sensing conditions.

[0003] The MES system is widely used in the existing market. However, the existing MES system needs to be customized according to the production line requirements during application. After the customization is completed and put into production, if there is a situation that seriously affects the production line during the production process of the production line, the MES system is prone to require manual adjustment of parameters, adjustment of production capacity, start-up of the production line and on-duty personnel, resulting in serious impact on the production capacity plan when the distribution is not timely or incorrect. Especially at present, affected by the power supply pressure, many intelligent manufacturing enterprises will implement power rationing during specific periods. When facing the power rationing problem, although the production capacity plan can be adjusted in advance, this adjustment is made manually outside the MES. After the manual adjustment, the adjusted production capacity plan is input into the MES system, resulting in the inability to perform intelligent adjustment easily when facing the power rationing problem, and the production capacity plan is prone to be disordered. Therefore, an MES system platform that can intelligently respond to the production capacity planning under the influence of power rationing is urgently needed to be solved. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an intelligent manufacturing MES platform, which has a power rationing adjustment function to achieve the effect of planning the production capacity of the platform when quickly responding to the changes in the production line caused by power rationing.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent manufacturing MES platform, including a production plan module, a production scheduling module, an inventory management module and an equipment management module;

[0007] An inventory table is configured in the inventory management module. The inventory table includes workpiece types and inventory quantities. The workpiece types represent the types of workpieces produced by the production line, and the inventory quantities represent the quantities of workpieces provided for production or sales corresponding to the workpiece types;

[0008] The production planning module includes a production line planning unit, a shift scheduling unit, and a startup allocation unit. The production line planning unit is configured with a production capacity planning strategy. The production capacity planning strategy includes generating production scheduling data based on the supply quantity and inventory quantity to form the number of workpieces to be produced, and generating a production line startup schedule based on the production scheduling data. The production line startup schedule represents the startup plan for controlling the production line to achieve the production scheduling data. The shift scheduling unit is configured with a shift scheduling strategy. The shift scheduling strategy includes allocating planned on-duty personnel based on the production scheduling data and the production line startup schedule. The startup allocation unit is configured with a startup strategy. The startup strategy includes controlling the equipment management module to allocate the corresponding production line for production based on the production scheduling data and the production line startup schedule;

[0009] The production scheduling module includes a power limit acquisition unit and a power limit regulation unit. The power limit acquisition unit is configured with an input port and an energy consumption detection subunit. The input port is used to input power limit data. The power limit data includes power limit time, power limit days, and power limit power. The energy consumption detection subunit is configured with a detection strategy. The detection strategy includes retrieving the production scheduling data and the production line startup schedule when the power limit data is detected, and obtaining startup power data based on the power consumed when the production line produces according to the production line startup schedule. The startup power data includes bus power and single-line power. The bus power represents the power required for all production lines to start up per working day, and the single-line power represents the power required for a single production line to start up per working day;

[0010] The power limit regulation unit is configured with a power limit adjustment strategy. The power limit adjustment strategy includes allocating production priorities based on the production scheduling data and the inventory quantity, retrieving the power limit data and the startup power data, and producing the power limit production scheduling data with the production lines required to start up according to the production priorities, and generating a power limit startup schedule based on the power limit production scheduling data. The shift scheduling strategy also includes allocating power limit on-duty personnel based on the power limit production scheduling data and the power limit startup schedule. When the power limit regulation unit generates the power limit startup schedule, it also generates corrected startup data. The corrected startup data is used to correct the production line startup schedule and form a corrected startup schedule. The startup allocation unit is used to receive the corrected startup schedule. The startup strategy also includes controlling the equipment management module to allocate the corresponding production line for production during power limit according to the corrected startup schedule.

[0011] As a further improvement of the present invention, the production line startup schedule includes a day shift startup plan and a night shift startup plan. The power limit adjustment strategy further includes:

[0012] The power limit time in the power limit data includes power limit production scheduling time and regular production scheduling time. The power limit production scheduling time represents the time period affected by power limit within a unit day, and the regular production scheduling time represents the time period with normal power supply within a unit day;

[0013] If the power outage time is within the time period of the day shift operation plan, then within the time period of the day shift operation plan, the day shift operation plan in the production line operation table is corrected according to the power outage production scheduling data and the power outage operation table to form a corrected operation table. The corrected operation table is the production line operation plan when the day shift operation plan in the production line operation table is replaced by the power outage operation table, and the night shift operation plan in the production line operation table is maintained. The equipment management module allocates the corresponding production line scheduling according to the corrected operation table.

[0014] If the power outage time exceeds the time period of the day shift operation plan and covers part of the time period of the night shift operation plan, the time period of the night shift operation plan is evenly divided. The night shift operation plan in the part affected by the power outage time is corrected according to the power outage production scheduling data and the power outage operation table to form the day shift operation plan and the night shift operation plan in the production line operation table during the time period affected by the power outage to form a corrected operation table. The corrected operation table replaces the time periods of the day shift operation plan and the night shift operation plan affected by the power outage with the power outage operation table, and the time periods of the night shift operation plan not affected by the power outage are maintained as the night shift operation plan. The equipment management module allocates the corresponding production line scheduling according to the corrected operation table and the night shift operation plan.

[0015] As a further improvement of the present invention, a proportional threshold is also preset in the power outage control unit. The power outage adjustment strategy includes judging the production priority of the corresponding workpiece in the production scheduling data. The power outage adjustment strategy also includes a proportional algorithm. The proportional algorithm is as follows:

[0016]

[0017] Where: t represents the ratio of the number of workpiece types in the production scheduling data to the inventory of the corresponding workpiece in the inventory, Q represents the production scheduling data, and D represents the inventory of the workpiece in the corresponding production scheduling data.

[0018] Set the proportional threshold as T. If t < AT, it indicates that the inventory is in urgent need. If AT < t < BT, it indicates that the inventory is normal. If BT < t < CT, it indicates that the inventory is sufficient. A, B, and C represent weight values, 1 > C > B > A. The generated priority includes first-level production scheduling, second-level production scheduling, and third-level production scheduling that decrease step by step. The first-level production scheduling level corresponds to the situation where the inventory of the workpiece is in urgent need. The second-level production scheduling level corresponds to the situation where the inventory of the workpiece is normal. The third-level production scheduling level corresponds to the situation where the inventory of the workpiece is sufficient.

[0019] As a further improvement of the present invention, in the power outage adjustment strategy, when determining the production of the production line to be started, the production line of the workpiece corresponding to the first-level production scheduling is scheduled according to the production priority of the workpiece in the production scheduling data. If the power outage power in the power outage data is greater than the single-line power, then the production line of the workpiece corresponding to the second-level production scheduling is allocated for scheduling. If the power outage power in the power outage data is less than the single-line power, only the production line of the workpiece corresponding to the first-level production scheduling is scheduled.

[0020] As a further improvement of the present invention, the power limit adjustment strategy further includes a production scheduling algorithm. The power limit production scheduling data of the production line is calculated according to the production scheduling algorithm. The production scheduling algorithm includes:

[0021]

[0022] Where: α represents the power limit operating rate, K represents the production line operating rate, P1 represents the power limit power, P represents the total line power, β represents the power limit production scheduling data, and γ represents the production scheduling data.

[0023] As a further improvement of the present invention, the production scheduling algorithm further includes:

[0024]

[0025] Where: P0 represents the single-line power, β0 represents the power limit production scheduling data of the single line, and β1 represents the production scheduling data according to the night shift operation plan.

[0026] As a further improvement of the present invention, a power limit release adjustment strategy is also configured in the power limit control unit. The power limit release adjustment strategy includes obtaining the power limit production capacity based on the number of power limit days and the power limit production scheduling data within the power limit days in the power limit data, and obtaining the expected achievable estimated production capacity based on the production scheduling data over the power limit days. The production capacity difference is obtained based on the estimated production capacity and the power limit production capacity. When the power limit is lifted, the production increase data and the production increase table are generated based on the production capacity difference, the production increase table and the production line operation table are added to generate the production increase operation table, and the planned on-duty personnel are allocated according to the production increase operation table.

[0027] As a further improvement of the present invention, the production increase algorithm is also included in the power limit release adjustment strategy. The production increase data is calculated according to the production increase algorithm. The production increase algorithm includes:

[0028] τ = θ * γ

[0029] τ0 = θ * β

[0030] Δτ = τ - τ0

[0031]

[0032] Where: τ represents the estimated production capacity, θ represents the number of power limit days, τ0 represents the power limit production capacity, Δτ represents the production capacity difference, Δτ1 represents the production capacity difference of the single line, δ represents the production increase proportion, and ε represents the weight.

[0033] As a further improvement of the present invention, the power limit release adjustment strategy further includes determining the production increase priority of the production increase production line according to the production capacity difference of the single line and the production increase proportion in the production increase operation table, arranging the production increase proportion of the single line from high to low step by step, and the production increase priority corresponding step by step to the high and low of the production increase proportion.

[0034] As a further improvement of the present invention, the limit adjustment strategy further includes corresponding allocation of planned on-duty personnel according to the production increase priority, and the number of planned on-duty personnel increases with the increase of the production increase priority.

[0035] The beneficial effects of the present invention: The production planning module plans the scheduling data for planned production according to demand during normal production, and plans the start-up schedule according to the scheduling data. The equipment management module is controlled according to the start-up schedule for production capacity production. The power limit data is input through the input port. During the power limit time, the production priority during power limit scheduling is set according to the scheduling data and the inventory quantity, and the production lines are allocated according to the power limit data and the start-up power data with the production priority for power limit scheduling, and the corresponding power limit start-up schedule is generated. The start-up schedule of the production line is corrected by generating the corrected start-up data, and the equipment management module is controlled according to the corrected start-up schedule for power limit scheduling during the power limit period, realizing the power limit adjustment function, so as to achieve the effect of quickly responding to the changes in the production line caused by the power limit and planning the production capacity on the platform.

[0037] The present invention will be further described in detail below with reference to the drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0038] Refer to Figure 1 As shown, a detailed implementation manner of an intelligent manufacturing MES platform of the present invention includes a production planning module, a production scheduling module, an inventory management module, and an equipment management module. An inventory table is configured in the inventory management module. The inventory table includes workpiece types and inventory quantities. The workpiece types represent the types of workpieces produced by the production line, and the inventory quantities represent the quantities of workpieces provided for production or sales corresponding to the workpiece types;

[0039] The production planning module includes a production line planning unit, a shift scheduling unit, and a startup allocation unit. A production capacity planning strategy is configured in the production line planning unit. The production capacity planning strategy includes generating production scheduling data based on the supply quantity and inventory quantity to form the number of workpieces to be produced, and generating a production line startup schedule based on the production scheduling data. The production line startup schedule represents the startup plan for controlling the production line to achieve the production scheduling data. A shift scheduling strategy is configured in the shift scheduling unit. The shift scheduling strategy includes allocating planned on-duty personnel based on the production scheduling data and the production line startup schedule. A startup strategy is configured in the startup allocation unit. The startup strategy includes controlling the equipment management module to allocate the corresponding production line for production based on the production scheduling data and the production line startup schedule;

[0040] The production scheduling module includes a power limit acquisition unit and a power limit regulation unit. An input port and an energy consumption detection subunit are configured in the power limit acquisition unit. The input port is used to input power limit data. The power limit data includes power limit time, power limit days, and power limit power. A detection strategy is configured in the energy consumption detection subunit. The detection strategy includes retrieving the production scheduling data and the production line startup schedule when the power limit data is detected, and obtaining startup power data based on the power consumed when the production line produces according to the production line startup schedule. The startup power data includes bus power and single-line power. The bus power represents the power required for all production lines to start up per working day. The single-line power represents the power required for a single production line to start up per working day;

[0041] A power limit regulation strategy is configured in the power limit regulation unit. The power limit regulation strategy includes allocating production priorities based on the production scheduling data and the inventory, retrieving the power limit data and the startup power data, and producing the power limit production scheduling data on the production lines required to start up according to the production priorities, and generating a power limit startup schedule based on the power limit production scheduling data. When generating the power limit startup schedule, the power limit regulation unit also generates corrected startup data. The corrected startup data is used to correct the production line startup schedule according to the power limit startup schedule and form a corrected startup schedule. The startup allocation unit is used to receive the corrected startup schedule. The startup strategy also includes controlling the equipment management module to allocate the corresponding production for production during power limit according to the corrected startup schedule. The shift scheduling strategy also includes allocating power limit on-duty personnel based on the power limit production scheduling data and the corrected startup schedule.

[0042] The production line startup schedule includes a day shift startup plan and a night shift startup plan. The power limit regulation strategy also includes:

[0043] The power limit time in the power limit data includes power limit production scheduling time and regular production scheduling time. The power limit production scheduling time represents the time period affected by power limit within a unit day. The regular production scheduling time represents the time period with normal power supply within a unit day;

[0044] If the power outage time is within the time period of the day shift operation plan, then within the time period of the day shift operation plan, the day shift operation plan in the production line operation table is corrected according to the power outage production scheduling data and the power outage operation table to form a corrected operation table. The corrected operation table is the production line operation plan when the day shift operation plan in the production line operation table is replaced by the power outage operation table, and the night shift operation plan in the production line operation table is maintained. The equipment management module allocates the corresponding production line scheduling according to the corrected operation table.

[0045] If the power outage time exceeds the time period of the day shift operation plan and covers part of the time period of the night shift operation plan, the time period of the night shift operation plan is evenly divided. The night shift operation plan for the part affected by the power outage time is corrected according to the power outage production scheduling data and the power outage operation table to form the day shift operation plan and the night shift operation plan for the time period affected by the power outage in the production line operation table, forming a corrected operation table. The corrected operation table replaces the time periods of the day shift operation plan and the night shift operation plan affected by the power outage with the power outage operation table, and the time periods of the night shift operation plan not affected by the power outage are maintained as the night shift operation plan. The equipment management module allocates the corresponding production line scheduling according to the corrected operation table and the night shift operation plan. This enables intelligent adjustment according to the time period of the power outage time, maintaining the expected production line operation situation for production when not affected by the power outage within a unit time, so as to increase the maximum production capacity within a unit number of days under the condition of being affected by the power outage.

[0046] A proportional threshold is also preset in the power outage control unit. The power outage adjustment strategy includes judging the production priority of the corresponding workpiece in the production scheduling data. The power outage adjustment strategy also includes a proportional algorithm. The proportional algorithm is as follows:

[0047]

[0048] Where: t represents the ratio of the number of workpiece types in the production scheduling data to the inventory of the corresponding workpiece in the inventory, Q represents the production scheduling data, and D represents the inventory of the workpiece in the corresponding production scheduling data.

[0049] Set the proportional threshold as T. If t < AT, it indicates that the inventory is in urgent need. If AT < t < BT, it indicates that the inventory is normal. If BT < t < CT, it indicates that the inventory is sufficient. Here, A, B, and C represent weight values, where 1 > C > B > A. The production priority includes first-level production scheduling, second-level production scheduling, and third-level production scheduling in a decreasing order. The first-level production scheduling level corresponds to the urgent need for workpiece inventory. The second-level production scheduling level corresponds to the normal workpiece inventory. The third-level production scheduling level corresponds to the sufficient workpiece inventory. In the power rationing adjustment strategy, when determining the production lines to be started, according to the production priority of the workpieces in the production scheduling data, the production lines corresponding to the workpieces in the first-level production scheduling are scheduled. If the power rationing power in the power rationing data is greater than the single-line power, then a part of the production lines corresponding to the workpieces in the second-level production scheduling are allocated for scheduling. If the power rationing power in the power rationing data is less than the single-line power, only the production lines corresponding to the workpieces in the first-level production scheduling are scheduled. It realizes generating different production priorities according to the proportional relationship between the corresponding workpiece quantity and the inventory in the production scheduling data, and thus preferentially schedules the urgently needed workpieces during power rationing, improving the reasonable adjustment of production volume.

[0050] The power rationing adjustment strategy further includes a production scheduling algorithm. According to the production scheduling algorithm, the power rationing production scheduling data of the production lines is calculated. The production scheduling algorithm includes:

[0051]

[0052] Among them: α represents the power rationing starting rate, K represents the production line starting rate, P1 represents the power rationing power, P represents the total line power, β represents the power rationing production scheduling data, and γ represents the production scheduling data.

[0053] The production scheduling algorithm further includes:

[0054]

[0055] Among them: P0 represents the single-line power, β0 represents the power rationing production scheduling data of the single line, and β1 represents the production scheduling data according to the night shift starting plan.

[0056] According to the production scheduling algorithm, the optimal power rationing production scheduling data that can be achieved under the limitation of the power rationing power and the best power rationing production scheduling data on a single production line during a unit working day are calculated, so as to obtain the expected requirements for production capacity plan allocation.

[0057] A power rationing release adjustment strategy is also configured in the power rationing control unit. The power rationing release adjustment strategy includes obtaining the power rationing production capacity based on the power rationing days in the power rationing data and the power rationing production scheduling data within the power rationing days, and obtaining the expected production capacity that can be achieved according to the production scheduling data based on the power rationing days. The production capacity difference is obtained based on the expected production capacity and the power rationing production capacity. When the power rationing is lifted, an increased production data and an increased production table are generated based on the production capacity difference. The increased production table and the production line starting table are added to generate an increased production starting table, and the planned on-duty personnel are allocated according to the increased production starting table.

[0058] The solution-limiting adjustment strategy also includes an output increase algorithm. The output increase data is calculated according to the output increase algorithm. The output increase algorithm includes:

[0059] τ = θ * γ

[0060] τ0 = θ * β

[0061] Δτ = τ - τ0

[0062]

[0063] Where: τ represents the expected production capacity, θ represents the number of days of power rationing, τ0 represents the power rationing production capacity, Δτ represents the production capacity difference, Δτ1 represents the production capacity difference of a single line, δ represents the proportion of output increase, and ε represents the weight.

[0064] Through the output increase algorithm, it can be calculated how to increase production to meet the production capacity requirements under normal production arrangement in the shortest time when adjusting the production capacity after the power rationing is lifted.

[0065] The solution-limiting adjustment strategy also includes determining the output increase priority of the production lines to be increased according to the production capacity difference of a single line and the proportion of output increase in the output increase schedule. The proportion of output increase of a single line is arranged step by step from high to low, and the output increase priority corresponds step by step to the level of the proportion of output increase. The solution-limiting adjustment strategy also includes allocating the planned on-duty personnel according to the output increase priority. The number of planned on-duty personnel increases as the output increase priority increases. It realizes controlling the production lines to increase production according to the output increase priority during output increase, and adjusting the on-duty personnel to assist in meeting the output increase requirements.

[0066] Working principle and its effects:

[0067] Through the production planning module, the production scheduling data for planned production according to requirements during normal production is planned, and the operation schedule is planned according to the production scheduling data. The equipment management module is controlled according to the operation schedule for production capacity production. The power rationing data is input through the input port. During the power rationing period, the production priority during power rationing scheduling is set according to the production scheduling data and the inventory, and the production lines are allocated for power rationing scheduling according to the power rationing data and the operating power data with the production priority, and the corresponding power rationing operation schedule is generated. The production line operation schedule is corrected by generating the corrected operation data, and the equipment management module is controlled according to the corrected operation schedule for power rationing scheduling during the power rationing period, realizing the power rationing adjustment function, so as to achieve the effect of quickly responding to the changes in the production lines caused by power rationing and planning the production capacity of the platform.
