Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic component transportation, in particular to a scheduling method and system. BACKGROUND

[0002] In the production of photovoltaic components, in order to improve production efficiency, multiple machines are generally used for production. The storage of the machine has a certain volume. When the material output on the machine reaches the storage volume of the machine, it will cause the machine to be stacked and stopped. Similarly, the operation of the machine also needs to be fed. When there is no feed on the machine, it will make the machine enter the standby state. In order to improve production efficiency, the transported material needs to be scheduled so that all machines are in working condition. However, in the existing scheduling system of transported material, only the transport trolley programmed in advance is used to transport the material to the machine, which cannot be adjusted according to the actual operation status of the equipment.

[0003] In the prior art, a tobacco material warehouse-out scheduling method, WCS, system and storage medium with application number "202010752503" are provided. The WCS receives material warehouse-out information and determines the warehouse-out material and the destination point. At the same time, the WCS receives the operation status of the logistics transportation equipment, selects the available logistics transportation equipment to transport the logistics, improves the transportation efficiency of the material, and reduces the waiting time of the material.

[0004] However, the prior art still has great defects, such as: in the actual material transportation environment, the material often shuttles in the transportation channel between the machines. When there is machine maintenance, transportation channel failure or obstacle, it will affect the transportation of the material, cause "traffic jam", and reduce the transportation efficiency of the material.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0048] Please refer to Figs. 1-2 The present application provides a technical solution:

[0049] A scheduling method, comprising the following steps:

[0050] S10, the RCS server receives the production task data and determines the production task amount;

[0051] S102, the RCS server determines the initial material conveying scheme according to the production task data, so that the conveying trolley conveying the material transports on the conveying path planned in the initial material conveying scheme;

[0052] S103, the WCS server reads the real-time field running data, and transmits the field running data to the RCS server when the field running data changes. Through real-time reading of the field running data, it is known in time whether there is an abnormality at the working machine and the material conveying channel, so as to avoid the abnormal point in the subsequent transportation of the conveying trolley;

[0053] S104, the RCS server isolates the material conveying path related to the abnormal working machine and material conveying channel in the initial material conveying scheme according to the field operation data, and screens out the reserved material conveying path, so that the conveying trolley avoids the abnormal point in transportation by reducing the conveying path, compared with the traditional transportation scheme, when the working machine and the material conveying channel are abnormal, it cannot be known and avoided in time, which is easy to cause the problem of "traffic jam", greatly improves the transportation efficiency, and the way of reducing the conveying path will not affect the direction of the conveying trolley on the reserved material conveying path, and the conveying trolley on the reserved material conveying path still continues to work, preventing the problem of decline of transportation efficiency caused by stopping of the conveying trolley;

[0054] By comparing the amount of material to be processed and the maximum processing load of the reserved material conveying path, it is judged whether the reserved material conveying path meets the production task requirement, so as to prevent the reserved material conveying path from failing to meet the production task requirement without timely knowing and making corresponding changes, which will adversely affect production.

[0055] S105, when the reserved material conveying path cannot meet the production task requirement, the RCS server screens the data of available working machines and material conveying channels according to the field operation data, re-forms the preselected material conveying path, and modifies the direction of the conveying trolley, so that the conveying trolley runs on the preselected material conveying path without adding new working machines, and the downtime is only the time for re-planning the material conveying path and moving the material conveying trolley, which has little effect on transportation efficiency;

[0056] By comparing the amount of material to be processed and the maximum processing load of the preselected material conveying path, it is judged whether the preselected material conveying path meets the production task requirement, so as to prevent the preselected material conveying path from failing to meet the production task requirement without timely knowing and making corresponding changes, which will adversely affect production.

[0057] S106, when the preselected material conveying path cannot meet the production task requirement, the WCS server transmits the position, processing load and material conveying channel of the working machine not recorded in the initial material conveying scheme to the RCS server, and the RCS server re-forms a new material conveying scheme according to the optimal processing load of the machine and the optimal transportation load of the material conveying channel.

[0058] Embodiment one:

[0059] In the battery piece production, the battery piece processed by the back plating film equipment needs to be transported to the positive plating film equipment for positive plating film process. In the battery piece production workshop, 17 back plating film equipment of model LDTW15 and 19 positive plating film equipment of model GZ2L2L-S are arranged. The back plating film equipment is provided with a discharge port, the positive plating film equipment is provided with a feeding port, a material conveying channel is formed between the discharge port and the feeding port, a plurality of AGV unmanned conveying trolleys are arranged on the material conveying channel, PLC programmable logic controllers of model CP1H-E, FX-5U or KV-7500 are arranged at the back plating film equipment, the positive plating film equipment and the material conveying channel, and WCS servers and RCS servers of model PowerEdge R450 and single-chip microcomputers of model STM32FT are arranged outside;

[0060] The PLC programmable logic controller transmits the number, position, processing load of the back plating film equipment and the positive plating film equipment, the distribution and arrangement of the material conveying channel between the back plating film equipment and the positive plating film equipment, the state of the back plating film equipment and the positive plating film equipment, the state of the material conveying channel and other working data to the WCS server in real time. The WCS server processes the working data and transmits it to the RCS server. The RCS server generates an initial material conveying scheme according to the WCS server and the production data. The initial material conveying scheme includes 12 back plating film equipment, 13 positive plating film equipment, 30 material conveying channels between the 12 back plating film equipment and the 13 positive plating film equipment, and 22 optimal material conveying channels are selected from the 30 material conveying channels, i.e. the initial material conveying scheme has 22 material conveying paths. The RCS server transmits the initial material conveying scheme to the single-chip microcomputer. The single-chip microcomputer receives the signal of the material conveying scheme and processes it. The single-chip microcomputer transmits the processed signal to the signal receiving part of the AGV unmanned conveying trolley, so that the AGV unmanned conveying trolley transports the battery piece at the discharge port of the back plating film equipment to the feeding port of the positive plating film equipment along the material conveying path.

[0061] When the state of the back plating film equipment and the positive plating film equipment in the initial material conveying scheme is abnormal, the WCS server transmits an abnormal signal to the RCS server. The RCS server isolates the material conveying path passing through the abnormal device position in the initial material conveying scheme according to the position data of the abnormal device, i.e. isolates the material conveying path related to the abnormal device from the original initial material conveying scheme, so as to screen out the reserved material conveying path, so that the subsequent material conveying process avoids the abnormal device, prevents the material from being conveyed to the abnormal working machine for the next step processing, causes the accumulation of materials and reduces the production efficiency.

[0062] When the material conveying channel in the initial material scheme is abnormal, the WCS server transmits an abnormal signal to the RCS server, and the RCS server isolates the material conveying path in the initial material conveying scheme that passes through the abnormal material conveying channel according to the abnormal material conveying channel data in the WCS server, that is, the material conveying path related to the abnormal material conveying channel is isolated from the original initial material conveying scheme, so as to screen out the reserved material conveying path, so that the subsequent material conveying process avoids the abnormal material conveying channel, so that the material avoids the abnormal material conveying channel in the conveying process, prevents the material from accumulating at the abnormal material conveying channel to cause "traffic jam", reduces the material conveying efficiency, and thus reduces the problem of low production efficiency.

[0063] The WCS server determines the actual processing material amount according to the operation data of the back plating film equipment and the front plating film equipment, and transmits the actual processing material amount to the RCS server. The RCS server obtains the remaining processing material amount according to the material processing amount and the actual processing material amount of the working machine, and determines the maximum processing load of the reserved material conveying path according to the maximum processing amount of the back plating film equipment and the front plating film of the reserved material conveying path and the maximum transportation amount of the material conveying channel. The required processing material amount and the maximum processing load of the reserved material conveying path are compared to determine whether the reserved material conveying path meets the production task requirement. If the reserved material conveying path meets the production task requirement, it is not necessary to change the material conveying path, and it is not necessary to intervene the material on the material conveying path, so that the conveying of the material is uninterrupted, preventing downtime from causing a decrease in transportation efficiency. In addition, the damage of the equipment on the production line can be repaired quickly, and the isolated material conveying path can be put into work immediately after the abnormal condition is removed. Therefore, the time for the reserved material conveying path to maintain the maximum processing load is short, and the impact on the working machine and the material conveying channel is small. If the reserved material conveying path fails to meet the production task requirement, the material conveying path needs to be re-planned to ensure the completion of the remaining work task.

[0064] Embodiment two:

[0065] Example 2 optimizes the scheduling method based on Example 1. When the retained material conveying path cannot meet the production task requirements, the material conveying path is replanned. The RCS server extracts and isolates abnormal back coating equipment, front coating equipment, material conveying channels, etc. from the WCS server. Based on the existing normally operating back coating equipment and front coating equipment, the material conveying path is replanned. That is, in addition to the retained material conveying path, material conveying channels that can transport between the existing normally operating back coating equipment and front coating equipment are added from the 8 non-optimal material conveying channels. This determines the pre-selected material conveying path. The travel direction of the conveying trolley is modified so that the conveying trolley travels on the pre-selected material conveying path without adding new workstations. The downtime is only the time used to replan the material conveying path and move the material conveying trolley, and the impact on transportation efficiency is minimal. By increasing the material conveying channels, the transportation load is increased, thereby meeting the production needs.

[0066] The RCS server determines the maximum processing load of the pre-selected material conveying path based on the maximum processing capacity of the back coating equipment and the front coating equipment, as well as the maximum transport capacity of the material conveying channel. It then compares the amount of material to be processed with the maximum processing load of the pre-selected material conveying path to determine whether the pre-selected material conveying path meets the production task requirements. If the pre-selected material conveying path cannot meet the production task requirements, new workstations and material conveying channels need to be added to ensure that the production task can be completed.

[0067] Example 3:

[0068] Example 3 further optimizes the scheduling method based on Example 2. When the pre-selected material conveying path cannot meet the production task requirements, the RCS server extracts the working data such as the position and processing load of the 5 back coating equipment and 6 front coating equipment that were not included in the initial material conveying plan from the WCS server. Based on the normally operating back coating equipment and front coating equipment and the newly added 5 back coating equipment and 6 front coating equipment, the RCS server re-plans the material conveying plan. The RCS server forms a new material conveying plan based on the optimal processing load of the back coating equipment and front coating equipment and the optimal transport load of the material conveying channel. By increasing the number of workstations and material conveying channels, the production task requirements are met.

[0071] The PLC programmable logic controller reads real-time operation data of the back plating film equipment, the positive plating film equipment and the material conveying channel, when the back plating film equipment or the positive plating film equipment is damaged, the back plating film equipment or the positive plating film equipment needs to be regularly maintained, the operation state of the back plating film equipment or the positive plating film equipment changes from normal operation to abnormal operation, when the back plating film equipment or the positive plating film equipment works again, the operation state of the back plating film equipment or the positive plating film equipment changes from abnormal operation to normal operation, so that the operation state of the back plating film equipment or the positive plating film equipment changes, at this time, the PLC programmable logic controller sends all the real-time operation data in the field to the WCS server, and when the material conveying channel is damaged, there is sundry on the material conveying channel which affects the transmission of the material, the operation state of the material conveying channel changes from normal operation to abnormal operation, when the material conveying channel returns to normal, the operation state of the material conveying channel changes from abnormal operation to normal operation, so that the operation state of the material conveying channel changes, at this time, the PLC programmable logic controller sends all the real-time operation data in the field to the WCS server, so that the staff can know the operation data of the equipment in the field in time, and the abnormal equipment can be maintained in time.

A scheduling system, characterized in that: include Data receiving module: Used by the RCS server to receive production task data; Conveying scheme formation module: used by the RCS server to determine the initial material conveying scheme based on production task data, and the conveying trolley transports materials along the material conveying path planned in the initial material conveying scheme; Abnormal data transmission module: used by the WCS server to read field operation data in real time and transmit field operation data to the RCS server when the field operation data changes; The first analysis module is used by the RCS server to isolate material conveying paths related to abnormal workstations and material conveying channels in the initial material conveying plan based on on-site operation data, and to filter out the material conveying paths to be retained so that the conveying trolley can avoid the material conveying paths related to abnormal workstations and material conveying channels, and to analyze whether the maximum transport load of the retained material conveying paths meets production requirements. The second analysis module is used to filter available machine tools and material conveying channel data based on field operation data through the RCS server when the retained material conveying path cannot meet production requirements. It then re-forms a pre-selected material conveying path and modifies the travel direction of the conveying trolley to ensure that the conveying trolley travels on the pre-selected material conveying path. If the retained material conveying path meets the production task requirements, there is no need to change the material conveying path or intervene in the materials on the material conveying path, ensuring uninterrupted material conveying. The module also analyzes whether the maximum transport load of the pre-selected material conveying path meets production requirements. The third analysis module is used when the pre-selected material conveying path cannot meet the production needs. The WCS server determines the actual amount of material processed by the machine based on the operating data of the machine on site, and sends the actual amount of material processed by the machine to the RCS server. The RCS server calculates the remaining amount of material to be processed based on the material processing amount and the actual amount of material processed by the machine. The WCS server transmits the positions, processing loads, and material conveying channels of the workstations that were not entered into the initial material conveying plan to the RCS server. The RCS server then regenerates a new material conveying plan based on the optimal processing load of the workstations and the optimal transport load of the material conveying channels.
