[0025] Next reference Figure 1 and 2 Various aspects according to the present invention are described in detail.

[0026] First reference Figure 1 , showing a schematic block diagram of a production control system 100 according to some embodiments of the present invention.

[0027] The production control system 100 may include various types of production equipment 10 , 12 deployed in a production workshop, a control device 20 for controlling the corresponding production equipment, a production control device 30 and a human-machine interface 40 .

[0028] The production equipment in the production control system 100 may include a variety of functional devices and auxiliary devices installed at different stations of the production line. For example, in some embodiments, these production equipment may be switch devices, and by switching the on / off state of the switch devices, the operating state of other production equipment, such as lighting equipment, inverters, motors, etc., may be further controlled. In some embodiments, these production equipment may be temperature regulating equipment, such as a heating furnace or a heating valve. In some embodiments, these production equipment may be energy storage equipment, such as a battery. In some embodiments, these production equipment may be fluid supply equipment, such as a coating equipment.

[0029] The control device 20 for controlling the corresponding production equipment can be configured as various forms of controllers, such as a PLC controller. These control devices 20 can be centrally stored in a control room or distributedly deployed in control cabinets next to the corresponding production equipment. These control devices 20 can control the operation of the production equipment based on control instructions from the production control device 30.

[0030] The human-machine interface 40 can be configured as a human-machine interactive operation interface to receive operations input by a staff member. The human-machine interface 40 can send the operations input by the staff member to the production control device 30 via a wired or wireless communication connection. In some embodiments, the human-machine interface 40 can be connected to the production control device 30 via a wired or wireless communication connection. In some embodiments, the production control system 100 may include a plurality of human-machine interfaces 40 arranged in a distributed manner.

In some embodiments, at least one storage module may be configured as a database to store predetermined data records, such as predetermined energy consumption levels pre-stored for predetermined production equipment, and the like.

[0032] Next reference Figure 2 , describes in detail an exemplary flow chart of a production control method according to some embodiments of the present invention. It should be understood that the steps of the method presented below are intended to be illustrative. In some embodiments, the method can be completed with one or more additional undescribed steps, and / or without one or more of the steps discussed. In addition, the order of the steps of the method shown in the figure and described below is not intended to be limiting.

[0033] like Figure 2 As shown, the production control method may include the following steps:

[0034] S10: Specify corresponding energy consumption levels for corresponding production equipment. For example, a first energy consumption level may be specified for the first production equipment 10 and a second energy consumption level may be specified for the second production equipment 12.

[0035] It should be understood that the first production equipment 10 can be understood as a first grouping of production equipment, which may include a certain number of one or more types of production equipment. The second production equipment 12 can be understood as a second grouping of production equipment, which may include a certain number of one or more types of production equipment. The energy consumption level can represent the energy-saving mode adopted for the corresponding production equipment. The first energy consumption level can be understood as a higher energy-saving mode, that is, the first production equipment 10 at the first energy consumption level can have a high energy-saving effect under the production control method of the present invention. The second energy consumption level can be understood as an energy-saving mode that is lower than the first energy consumption level. In some embodiments, more energy consumption levels can be specified, for example, a third energy consumption level can be specified for a third production equipment, etc.

[0036] In some embodiments, a second energy consumption level may be specified for production equipment that takes a long time to reach a target state, while a first energy consumption level may be specified for production equipment that takes only a short time to reach a target state. As an example, the first energy consumption level may be specified for the following first production equipment 10: switchgear, inverter, display, and / or lighting equipment. The second energy consumption level may be specified for the following second production equipment 12: temperature regulating equipment (e.g., heating furnace or heating valve), energy storage equipment (e.g., battery), and / or fluid supply equipment (e.g., coating equipment).

[0037] In some embodiments, the allocation relationship between the production equipment and the energy consumption level can be pre-stored in a database, and the production control device 30 can call the database to obtain the energy consumption level specified for the corresponding production equipment. In some embodiments, the allocation relationship between the production equipment and the energy consumption level pre-stored in the database can be manually adjusted or modified.

[0038] S20: Obtaining production shift information, where the production shift information may include a series of start and end times of production shifts. For example, the production control device 30 may obtain the production shift information from the production control system 100, such as a predetermined database and / or the human-machine interface 40. In some embodiments, the production shift information may be manually adjusted or modified so as to update the production shift information in real time.

[0039] S30: Automatically generate a first automatic start-stop control instruction for the first production equipment 10 and a second automatic start-stop control instruction for the second production equipment 12 according to the production shift information, wherein the first automatic start-stop control instruction prompts the first production equipment 10 to be started at a first start time and the first production equipment 10 to be shut down at a first shut-down time, and the second automatic start-stop control instruction prompts the second production equipment 12 to be started at a second start time and the second production equipment 12 to be shut down at a second shut-down time. According to the present invention, the first start time may be set to be synchronized with the start time of the production shift or to be ahead of the start time of the production shift, and the second start time may be set to be ahead of the first start time, wherein the first shut-down time may be set to be synchronized with the end time of the production shift or to be behind the end time of the production shift, and the second shut-down time may be set to be behind the first shut-down time.

[0040] Therefore, according to the production control method of the present invention, the first production equipment 10 and the second production equipment 12 can be automatically shut down and started during the non-production period between two production shifts, thereby reducing the operating energy consumption of the corresponding production equipment in an efficient manner. Advantageously, the first production equipment 10 that can reach the target state in a short time or can reach the target state immediately can stop running for a longer time during two production shifts, for example, more than 90% and remain stopped, thereby achieving a higher energy saving target. The second production equipment 12 that takes a longer time to reach the target state can stop running for a moderate time during two production shifts, for example, more than 60% or 70% and remain stopped, thereby achieving a moderate energy saving target, while at the same time reducing the negative effects caused by frequent shutdown and startup of the second production equipment 12, such as reduced production efficiency and / or damage to production equipment.

[0041] In some embodiments, the production control method according to the present invention may provide that: the second automatic start-stop control instruction causes the second production equipment 12 to be automatically shut down after a predetermined time period, such as 30 minutes or 1 hour, after the end of the production shift. The selection of the predetermined time period may be determined based on historical statistical data, which may characterize the probability of the second production equipment 12 being required to perform additional production tasks due to missed production or temporary failures, and the median duration or average duration of performing the additional production tasks. In some embodiments, if the probability of the second production equipment 12 being required to perform additional production tasks is higher than a predetermined threshold, such as 30%, 40%, 50%, or 60%, the median duration or average duration of performing the additional production tasks is set to the predetermined time period.

[0042] In some embodiments, the production shift information may also include the start time and end time of the rest period in each production shift. Advantageously, the production control method may include S40: automatically generating a first automatic start-stop control instruction for the first production equipment 10 and a second automatic start-stop control instruction for the second production equipment 12 according to the production shift information, wherein the first automatic start-stop control instruction prompts the first production equipment 10 to be started at a third start time and the first production equipment 10 to be shut down at a third shut-down time, and the second automatic start-stop control instruction prompts the second production equipment 12 to be kept started during the rest period, wherein the third shut-down time is set to be synchronized with the start time of the rest period or to lag behind the start time of the rest period, and the third start time is set to be synchronized with the end time of the rest period or to be ahead of the end time of the rest period.

[0043] Therefore, according to the production control method of the present invention, the first production equipment 10 that only needs a short time to reach the target state can stop running for a long time during the rest period in each production shift, for example, keep it stopped for more than 80%, thereby achieving a higher energy saving target. The second production equipment 12 that needs a long time to reach the target state can keep running during the rest period in each production shift, thereby avoiding the negative effects caused by frequent shutdown and startup of the second production equipment 12, such as reduced production efficiency and / or damage to the production equipment.

[0044] In some embodiments, the production control method according to the present invention may provide for the following steps:

[0045] S50 : Obtaining a first manual start / stop control instruction for the first production equipment 10 and a second manual start / stop control instruction for the second production equipment 12 from the human-machine interface 40 .

[0046] S60: Assign a first priority to the first manual start-stop control instruction and the second manual start-stop control instruction, and assign a second priority to the first automatic start-stop control instruction and the second automatic start-stop control instruction, wherein the first priority is higher than the second priority, thereby allowing the first manual start-stop control instruction and the second manual start-stop control instruction to be executed before the first automatic start-stop control instruction and the second automatic start-stop control instruction.

[0047] Advantageously, the production control method according to the present invention allows automatic start-stop control and manual start-stop control for corresponding production equipment, thereby realizing a flexible and efficient start-stop control strategy. Advantageously, the production control method according to the present invention stipulates that the priority of manual start-stop control is higher than the priority of automatic start-stop control, thereby efficiently and reliably allowing manual triggering of immediate shutdown or immediate startup of production equipment due to emergency events.

[0048] In some embodiments, in order to allow manual start-stop control, the human-machine interface 40 may include a start-stop status display area for the corresponding production equipment, in which the current start-stop status of the corresponding production equipment, the duration of the current start-stop status, and / or the time interval from the next start-stop status switch can be presented. Thus, the staff can intuitively and quickly grasp the current operating status of the corresponding production equipment. Additionally or alternatively, the start-stop status display area may include a start block and a stop block, and the status presentation of the start block and the stop block can indicate the current start-stop status of the corresponding production equipment. For example, a manual start control instruction can be triggered by operating the start block, and a manual stop control instruction can be triggered by operating the stop block. Thus, efficient manual start-stop control can be achieved.

[0049] Advantageously, the production control method according to the present invention may provide that: for the second production equipment 12, when the duration in the current startup state is less than a predetermined threshold, at least two operations of the shutdown block are required to allow manual shutdown of the corresponding second production equipment 12, and when the duration in the current shutdown state is less than the predetermined threshold, at least two operations of the start block are required to allow manual startup of the corresponding second production equipment 12. Additionally or alternatively, the production control method according to the present invention may provide that: when the duration in the current startup state is less than a predetermined threshold, manual shutdown of the corresponding second production equipment 12 is prohibited; and / or when the duration in the current shutdown state is less than a predetermined threshold, startup of the corresponding second production equipment 12 is prohibited. This can reduce the negative impact caused by frequent shutdown and startup of the second production equipment 12, such as reduced production efficiency and / or damage to production equipment.

[0050] Additionally or alternatively, the production control method according to the present invention may provide for the following steps:

[0051] S70: Record multiple manual start-stop control instructions for corresponding production equipment; count multiple manual start times and multiple manual shutdown times involved in the multiple manual start-stop control instructions; when the counted manual start time and manual shutdown time meet the predetermined statistical law, adjust the automatic start time and automatic shutdown time of the automatic start-stop control instruction for the corresponding production equipment based on the counted manual start time and manual shutdown time. In this way, the automatic start time and automatic shutdown time of the automatic start-stop control instruction can be made more in line with the actual production needs, further improving the user experience of the production control method.

[0052] Additionally or alternatively, the production control method according to the present invention may provide for the following steps:

[0053] S80: automatically generating a plurality of second automatic start-stop control instructions for the second production equipment 12 according to the production shift information, wherein the plurality of second automatic start-stop control instructions have second start times and second stop times that are different from each other;

[0054] S90: activating one of the plurality of second automatic start / stop control instructions for a plurality of predetermined production shifts, and calculating a first average energy consumption index during the plurality of predetermined production shifts;

[0055] S100: activating another second automatic start-stop control instruction among the plurality of second automatic start-stop control instructions for a plurality of predetermined production shifts, and calculating a second average energy consumption index during the plurality of predetermined production shifts;

[0056] S110: Compare the first average energy consumption index with the second average energy consumption index, and select the second automatic start-stop control instruction associated with the lower average energy consumption index as the effective second automatic start-stop control instruction.

[0057] Therefore, according to the production control method of the present invention, an energy consumption optimization scheme can be selected according to actual operation data, thereby further improving the rationality and reliability of the start-stop control instructions.

[0058] In some embodiments, the production control method according to the present invention may provide for: finding out the failure rate of the corresponding production equipment; when the failure rate of the corresponding production equipment is higher than the first predetermined threshold, adjusting the automatic start time and automatic shutdown time of the automatic start-stop control instruction for the corresponding production equipment. Additionally or alternatively, the production control method according to the present invention may provide for: when the failure rate of the corresponding production equipment is higher than the second predetermined threshold, the automatic start-stop control instruction is not allowed for the corresponding production equipment, and only the manual start-stop control instruction is allowed. Thus, the production control method according to the present invention can well balance the energy-saving target and equipment failure, thereby obtaining a more optimized production control solution.

[0059] The invention being thus described, it will be obvious that the invention may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications obvious to one skilled in the art are intended to be included within the scope of the following claims.
