Description

Technical Field

[0001] The invention relates to the technical field of supply chain and warehouse management. Background Art

[0002] The automotive supply chain purchases relatively more auto parts in bulk and supplies them to various factories. The status of each batch of parts and the visibility of parts data are relatively poor, and there is currently no better solution. In addition, after the supply chain centrally purchases, the parts in the warehouse are just stacked. During the stacking process, the data information is simply summarized and then registered for easy retrieval and inventory.

[0003] For example, the public document with announcement number CN111311160A, publication date June 19, 2020, and patent name "Method for Intelligent Operation of Automobile Parts Warehouses", the disclosed method includes: the master data docking process, which is for the warehouse management system to capture the material card information sent to the intermediate database by the upper system in real time or import the material card information through manual forms; the warehousing process includes the automated warehousing mode and the workbench cycle warehousing mode to complete the shelving and warehousing of goods; the outbound process includes the upper system order outbound process and the warehouse management system order outbound process; the tallying process is used for the warehouse management system to recommend mergeable shelves according to the loading rate, and to tally the corresponding shelves; the inventory process is used for the warehouse management system to create inventory vouchers according to the different attributes of parts, and to check and modify the inventory.

[0004] Similar to the above-mentioned statistical method for automobile parts, data information cannot be obtained during the storage process, so the impact of the storage environment on parts cannot be obtained. If some environmentally sensitive parts are involved, it is not convenient to trace the source and find abnormal parts due to storage problems. In addition, when staff are looking for parts in the warehouse, they need to search by number. If they need to skillfully find the stored parts, they need to have a certain level of warehouse management proficiency.

[0005] Therefore, there is a need for a system and method for warehouse management and recording of centralized procurement in automobile supply chain centralized procurement control systems, which has more data statistics and is more convenient for recording. Summary of the invention

[0012] Each product in the cargo box is provided with a QR code, which contains the product name, weight information, and production information of the product;

[0013] The magnetic information board is a universal device. When the magnetic information board is adsorbed onto the shelf layer, the weighing unit in the cargo box storage area of ​​the layer is activated. The weighing unit transmits its own number information to the magnetic information board, and the magnetic information board transmits the weighing unit's own number information to the server to obtain the positioning information of the magnetic information board.

[0014] The warehouse is pre-divided into storage areas, and a lighting system is provided above each storage area. The lighting system includes a lighting lamp connected to a power source and a light controller that controls the operation of the lighting lamp.

A ZigBee module that communicates with a ZigBee device is provided in the lighting system, and the ZigBee module is connected to the light controller.

[0015] Some of the lighting systems have an environmental monitoring module, which is connected to and outputs a sensing signal to the ZigBee module, and transmits the collected signal to the ZigBee device through the ZigBee module and is stored by the server. Each environmental monitoring module determines a monitoring area based on its location. The monitoring areas of all environmental monitoring modules do not overlap and cover the entire warehouse area. The server stores the environmental data information collected by the environmental monitoring module in the storage information of all goods in the monitoring area.

[0016] The front of the magnetic information board is also provided with a communication connector connected to the processor, and the indicator lights include a pickup indicator light for indicating the pickup location, a placement indicator light for indicating the placement location, a status indicator light for indicating whether there is a storage problem, and a working condition indicator light for indicating its own working condition.

[0017] An operating method of an automobile supply chain centralized procurement control system:

[0018] Inventory method:

[0019] Click the inventory option on the scanning device to start the scanning camera;

[0020] Scan the QR code of the product with a scanning device;

[0021] The code scanning device identifies the product information and obtains similar product storage information from the server;

[0022] The code scanning device displays self-deposit or automatic deposit for the staff to choose;

[0023] If you choose to store the goods by yourself, the staff will scan the QR code on the magnetic information board, and then put the goods into the cargo box where the magnetic information board is located. After the weighing unit under the cargo box obtains the correct weight increase signal, it will update the data information to the server. At the same time, the server will send a signal to the scanning device that the self-storage is completed, and the scanning device will issue a prompt;

[0024] If automatic storage is selected, the server will provide the storage location of the goods according to the set logic based on the identified goods information, and transmit the storage location information to the scanning device for display. At the same time, the release indicator light of the magnetic information board at the storage location will be controlled to light up, and the green pickup light source of the lighting system at the location of the magnetic information board will be lit. When the weighing unit at the storage location obtains the correct weight increase signal, the data information will be updated to the server. At the same time, the server will send a signal to the scanning device that self-storage is completed, and the scanning device will issue a prompt, and at the same time, the lit release indicator light and green pickup light source will be turned off.

[0025] Pickup method:

[0026] Click the pickup option on the scanning device;

[0027] The code scanning device displays self-pickup and query pickup for staff to choose;

[0028] If you choose to pick up the goods by yourself, start the scanning camera, scan the goods you have taken out, and the touch screen will display the goods information and whether you are sure to pick up the goods. If you choose yes, the pickup information will be updated to the server. If you put the goods back to their original place, it will be determined if you choose no.

[0029] If you choose to query and pick up the goods, the touch screen will display the goods query information. After selecting the goods to be picked up, the pickup indicator light on the magnetic information board at the storage location will be controlled to light up according to the storage location of the goods. At the same time, the red cargo release light source of the lighting system at the location of the magnetic information board will be lit.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is a brief description of the contents expressed in each figure in the specification of the present invention:

[0037] Figure 1 This is the principle block diagram of the automobile supply chain centralized procurement control system. DETAILED DESCRIPTION

[0038] The following is a further detailed description of the specific implementation methods of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, the manufacturing process and operation method, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0039] The automobile supply chain centralized procurement control system mainly involves the intelligent management of warehouses in centralized procurement. In warehouse management, it is difficult to find items that are not frequently used, and it will also increase the difficulty of storage management when they are put into storage. Login and input are complex operations. If any of the environments is wrong, it will affect the overall accuracy of the storage data in the warehouse, and large deviations will appear over time.

[0040] This system uses the server for overall data storage. The server uses a high-configuration PC device with a display and input devices (keyboard and mouse) to facilitate operation and viewing. The server is generally placed in the management room of the warehouse. In order to notify the staff in time when an abnormality occurs, the server can be equipped with an alarm device, such as an intelligent speaker, which can be activated when an alarm is triggered to emit a preset alarm prompt tone.

[0041] In order to facilitate communication with other devices, the server is connected to a wifi device and a ZigBee device, and communicates wirelessly with other devices through the wifi device and the ZigBee device. The wifi device realizes wireless communication with the code scanning device, that is, the network port of the server communicates with the code scanning device through the WiFi device; the communication port of the server is connected to the ZigBee device, and uses the ZigBee device to communicate with the storage equipment, and the storage equipment includes a shelf system, a lighting system, and a magnetic information board.

[0042] The main body of the shelf system is the shelves placed in the warehouse. The shelves are placed side by side on the ground. Generally, there are multiple rows according to the warehouse area. There are channels between the shelves for communication between staff and vehicles (trucks). Each shelf is provided with a shelf, and each shelf is provided with a cargo box storage area for placing cargo boxes. In order to facilitate record keeping, each cargo box storage area has an independent number, such as the shelf where the row and column are located + the number of the shelf layer + the position of the shelf. For example, the shelf in the fourth row and the eleventh column, in the second cargo box storage area from the right on the fourth layer of the shelf, can be numbered 04-11-4-2. Of course, this is just an enumeration, and other numbering methods can also be used.

[0043] The outer side edge of each layer is provided with a lower flange structure, and the lower flange is an iron structure, which is convenient for adsorbing the magnetic information board. The cargo boxes and shelves used in this system are preferably of uniform models, so that they can be stored neatly. In order to ensure that the placement of each cargo box is fixed, each cargo box storage area is provided with a cargo box groove. The size of the cargo box groove matches the size gap of the bottom of the cargo box. When the cargo box is placed in the cargo box storage area, it can be embedded in the correct position. At the same time, a magnetic information board groove is provided in the middle position of the layer where each cargo box storage area is located. The size of the magnetic information board groove matches the size gap of the back of the magnetic information board. When the magnetic information board is adsorbed on the layer, it can also be embedded in the magnetic information board groove, thereby ensuring that the cargo box and the magnetic information board are placed neatly.

[0044] The cargo boxes and magnetic information boards are placed neatly so that the shelf system can be better connected to the system. The shelf system connects each shelf to the power supply and supplies power to each cargo box storage area. It is necessary to lay the wires in advance to provide low-voltage DC power to the cargo box storage area. Two power lines are introduced into each cargo box storage area. It is recommended to run the lines along the bottom of the shelf board, which can improve the overall aesthetics. Wire troughs can be preset. Among the two power lines introduced into each cargo box storage area, one power line is connected to the weighing unit in the cargo box groove. The weighing unit is placed in the middle of the cargo box groove to obtain the weight of the cargo box and the items inside it, and use the weight to verify the data. Except for extremely light items (such as small foam items), relatively heavy items can obtain the storage weight by weight. The other power line is connected to the contact electrode in the groove of the magnetic information board, which can be This is the power supply for the magnetic information board, so that the magnetic information board is wirelessly equipped with batteries and can ensure the stability of power supply. A signal connector is provided next to the contact electrode, and a contact that cooperates with the contact electrode and the signal connector is provided on the back of the magnetic information board. The contact on the magnetic information board that contacts the contact electrode is connected to the power supply, and the contact that contacts the signal connector is connected to the processor. The weighing unit is connected to the signal connector through a signal line to transmit its own number information and weighing information to the connected magnetic information board. The contact can be set as a protruding elastic metal part, which can ensure that the contact and the contact electrode and the signal connector are in reliable contact after magnetic attraction. The magnetic information board can be set with a limit structure for reverse placement as needed, and is equipped with a limit structure on the groove of the magnetic information board to avoid contact disconnection and connection failure between the contact and the contact electrode and the signal connector due to placement problems.

[0045] All magnetic information boards are the same device, so they can be used interchangeably. When the magnetic information board is adsorbed onto the shelf layer, it will power on. After power-on, it will send an activation signal to the connected weighing unit to activate the weighing unit in the cargo box storage area of ​​the layer. The weighing unit will transmit its own number information (cargo box storage area number) to the magnetic information board, and the magnetic information board will transmit the weighing unit's own number information to the server. The server will also define the cargo box storage area number as the number of the magnetic information board, and the magnetic information board will be able to obtain a position according to the number. If there is no cargo box in the cargo box storage area, there will be no magnetic information board. When you start using a cargo box storage area, you need to place an empty cargo box on the cargo box storage area first, and then adsorb a magnetic information board on it. After the weighing unit is activated, the weight of the cargo box is obtained. If it is abnormal (too light or too heavy), the server will be prompted with the corresponding problem, and work needs to be processed to cancel the abnormality. If it is normal, the precise weight of the cargo box is obtained and peeled. After that, you need to put goods into the empty cargo box within the specified time, otherwise the empty cargo box removal alarm will be issued. When the last goods in a cargo box are taken out, the server will also require the removal of the cargo box and the magnetic information board in the cargo box storage area. This alarm prompts the empty cargo box removal alarm.

[0046] Each item in the cargo box is equipped with a QR code, which contains the product name, weight information, production information, and storage information of the item. The storage information of the item can record the storage time information, storage environment change information, etc.

[0047] The magnetic information board is a long strip structure, and its overall size is similar to that of a remote control. An indicator light and a QR code are provided on the front of the magnetic information board. The QR code contains the ID information of the magnetic information board. The ID information is the cargo box storage area number obtained by placing it in the cargo box storage area. A communication connector connected to its internal processor can also be provided on the front of the magnetic information board. The communication connector is connected to the processor, and the communication connector can be used to electrically connect to other devices to perform maintenance or system updates on the processor. The indicator lights are side-by-side light bulbs, including a pickup indicator light that indicates the pickup location (usually green and very bright), a placement indicator light that indicates the placement location (usually red and very bright), a status indicator light that indicates whether there is a problem with the storage (usually yellow and very bright), and a working condition indicator light that indicates its own working condition. (usually white, always on)), when there are goods to be taken away from the cargo box storage area where the magnetic information board is located, the pick-up indicator light is on, when the pick-up is over or there is no pick-up demand, the pick-up indicator light is off, when there are goods to be stored in the cargo box storage area where the magnetic information board is located, the release indicator light is on, when the protection is over or there is no release demand, the release indicator light is off, when there are more or less goods in the cargo box storage area where the magnetic information board is located, and there is an abnormal pick-up and release situation, the status indicator light is on or flashing, under normal circumstances or after returning to normal, the status indicator light is off, when the magnetic information board is powered on and works normally, the working condition indicator light is always on, indicating that the work is normal, and it is also convenient for inspections to observe the working condition of each magnetic information board, when the magnetic information board self-checks the working condition abnormally, the working condition indicator light flashes rapidly. The indicator light is convenient for staff to find the cargo box storage area they need in time when they arrive near the shelf.

[0048] The back of the magnetic information board is provided with a device for adsorbing on the outer side of the shelf layer board. A processor, a power supply, and a ZigBee module are arranged inside the magnetic information board. The power supply is connected to the power supply contacts, and the processor and the power supply end of the ZigBee module are connected through a power cord. The processor has a built-in memory and communicates with the ZigBee device using the ZigBee module, thereby realizing communication with the server. The signal output end of the processor is connected to an indicator light, and different indicator lights are controlled according to different states to work according to the set program.

[0049] The barcode scanning device is a conventional handheld computer. You can use the corresponding APP installed on your mobile phone, or you can use a dedicated PDA. If you need to set up multiple devices, multiple staff members can use them at the same time. The barcode scanning device has a touch screen on the front and a barcode scanning camera on the back. The barcode scanning device has a battery and a controller. The touch screen and the barcode scanning camera are connected to the controller. The controller has a built-in communication module and memory, and uses the communication module to communicate with the WiFi device.

[0050] In addition to the conventional lighting function, the lighting system also has environmental monitoring and cooperates with the magnetic information board to find the storage or retrieval location of goods. The warehouse is pre-divided into storage areas, and a lighting system is installed above each storage area. Fixed shelf numbers are specified in each divided area, and the cargo box storage areas on these shelves are all within the "jurisdiction" of the lighting system. The lighting system includes lighting lamps connected to the power supply and light controllers that control the operation of the lighting lamps. The main function is still lighting, but the lighting lamps are provided with at least three colors, including white lighting sources, green light sources for picking up goods, and red light sources for putting away goods. The white lighting source is a lighting lamp that is always on and is used for lighting inside the warehouse. The green light source for picking up goods and the red light source for putting away goods cooperate to realize the lighting prompt function. The lighting system is equipped with a ZigBee module that communicates with the ZigBee device. The ZigBee module is connected to the light controller, and the server can collaboratively control each lighting system.

[0051] Some of the lighting systems described above have an environmental monitoring module. Generally, an environmental monitoring module is set in the "jurisdiction" of several lighting systems together. The environmental monitoring signal of the lighting system with the environmental monitoring module communicates with the server through the internal ZigBee module. The environmental monitoring module connects and outputs the sensing signal to the ZigBee module, and transmits the collected signal to the ZigBee device through the ZigBee module and is stored by the server. Each environmental monitoring module determines the monitoring area according to its location. The monitoring areas of all environmental monitoring modules do not overlap and cover the entire warehouse area. The server stores the environmental data information collected by the environmental monitoring module in the storage information of all goods in the monitoring area. The storage information includes the ambient temperature, humidity, and the detection sensors added according to the storage needs. The environmental monitoring module generally collects the information once at a set interval. After the collection, it will be transmitted to the server for storage, and the collected storage information will be stored on all goods in the "jurisdiction" of the environmental monitoring module, forming historical data, which is convenient for warehousing traceability tracking of each product.

[0052] The operation method of the above-mentioned automobile supply chain centralized procurement control system is as follows, which generally includes inventory methods and pickup methods, both of which require staff to operate with handheld scanning equipment. The server generally performs overall control, such as taking away a cargo box as a whole. When selected, the lighting system and magnetic information board of the cargo box at the corresponding position will light up, prompting the staff to go and take it, which can improve the efficiency of taking, but in most cases it is the processing of a single product:

[0053] The initial interface of the scanning device displays two selection modules: inventory options and release options;

[0054] Inventory method:

[0055] Click the inventory option on the scanning device to start the scanning camera;

[0056] The scanning device scans the QR code of the product and needs to interact with the server to retrieve data during identification;

[0057] The code scanning device identifies the product information and obtains similar product storage information from the server;

[0058] The code scanning device displays self-deposit or automatic deposit for the staff to choose;

[0059] Self-storage means that the staff places the goods in a suitable location based on their experience. If self-storage is chosen, the staff arrives at the storage location, scans the QR code on the magnetic information board, and then puts the goods into the cargo box where the magnetic information board is located. After the weighing unit under the cargo box obtains the correct weight increase signal, it updates the data information to the server. At the same time, the server sends a signal to the scanning device that self-storage is completed, and the scanning device issues a prompt. If the weight increase is abnormal, an alarm will be triggered and the staff needs to find out the cause and deal with it separately.

[0060] Automatic storage allows the system to follow the set procedures, such as categorizing and storing in chronological order, and arrange appropriate placement locations for staff. If automatic storage is selected, the server will provide the storage location of the goods according to the set logic based on the identified goods information, and transmit the storage location information to the scanning device for display. At the same time, the release indicator light of the magnetic information board at the storage location will be controlled to light up, and the green pickup light source of the lighting system at the location of the magnetic information board will be lit. The lighting system prompts the approximate storage location, and the magnetic information board prompts the exact placement location. Combined with the cargo box storage area number displayed by the scanning device, the storage location can be found accurately and quickly. When the weighing unit at the storage location obtains the correct weight increase signal, the data information will be updated to the server. At the same time, the server will send a signal to the scanning device that the storage is completed, and the scanning device will issue a prompt, and at the same time turn off the lit release indicator light and the green pickup light source. If the weight increase is abnormal, an alarm will be triggered, and the staff needs to find out the reason and deal with it separately.

[0061] Pickup method:

[0062] Click the pickup option on the scanning device;

[0063] The code scanning device displays self-pickup and query pickup for staff to choose;

[0064] If you choose to pick up the goods by yourself, start the scanning camera, scan the goods you have taken out, and the touch screen will display the goods information and whether you are sure to pick up the goods. If you choose yes, the pickup information will be updated to the server. If you put the goods back to their original place, it will be determined if you choose no.

[0065] If you choose to query and pick up the goods, the touch screen will display the goods query information. You need to enter the corresponding product name or product number. After selecting the goods to be picked up, the server will take the goods with the longest storage time first in order of storage time. Then, according to the storage location of the goods, the server will control the pickup indicator light on the magnetic information board at the storage location to light up, and at the same time, the red cargo release light source of the lighting system at the location of the magnetic information board will be lit. When the weighing unit at the storage location obtains the correct weight reduction signal, the data information will be updated to the server. At the same time, the server will send a signal to the scanning device that the self-pickup is completed, and the scanning device will issue a prompt, and at the same time, the lit cargo release indicator light and green cargo pickup light source will be turned off.

[0066] When the environmental data obtained by the environmental monitoring module is abnormal, the green pickup light source and the red delivery light source of the lighting system where the environmental monitoring module is located flash alternately, and the server issues an alarm;

[0067] When the working condition of the magnetic information board is abnormal, the working condition indicator light will light up. When the weight in the cargo box where the magnetic information board is located changes abnormally, the status indicator light will light up. When the working condition indicator light or the status indicator light is on, the server will alarm and control the lighting system where the magnetic information board is located so that the green pickup light source and the red delivery light source are always on at the same time.

[0068] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
