Description

Technical Field

[0001] This invention belongs to the field of wireless positioning and warehouse management technology, specifically relating to an audio-visual positioning system based on Bluetooth beacons. Background Technology

[0002] Currently, there are various technical forms in the field of material search management in small and medium-sized factories. In material search management, the traditional manual management mode is still the main method in some factories without ERP or other management systems. Under this mode, material management relies entirely on the experience and memory of warehouse staff. When searching for materials, it is necessary to manually search or check paper documents, which is not only time-consuming and labor-intensive, but also prone to searching for the wrong materials or not being able to find the materials. At the same time, manual data entry is inefficient and has a high error rate, often leading to production line shutdowns waiting for materials, resulting in idle equipment and wasted manpower.

[0003] For factories that have already deployed ERP and other management systems, a semi-digital management model based on these systems is often adopted. While this model achieves digital management of inventory data, the core function of ERP and other management systems lies in data statistics and management, which cannot solve the core problem of material physical location. This leads to a disconnect between theoretical storage locations and actual material locations, and material retrieval still relies on manual labor. In addition, existing technical solutions cannot fully utilize the QR codes / barcodes generated by ERP and other management systems, and data entry still relies on manual operation, further reducing management efficiency and easily causing data errors. In dedicated short-range communication-assisted retrieval solutions, RFID solutions can only achieve regional identification of materials, cannot provide accurate audio and visual prompts, and have high deployment costs, and the equipment cannot be reused, resulting in poor practicality. Existing low-power Bluetooth beacon solutions require the installation of dedicated apps and dedicated hardware, with complex operation processes, easily forming "data silos," and unable to achieve flexible collaboration with ERP and other management systems. They also have many problems such as insufficient prompt volume, poor battery life, high security risks, lack of power monitoring, and rigid binding relationships. The 433MHz solution has the defects of high standby power consumption and poor versatility, making it difficult to adapt to the diverse needs of small and medium-sized factories. Summary of the Invention

[0004] The purpose of this invention is to provide a Bluetooth beacon-based audio-visual positioning system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a Bluetooth beacon-based audio-visual prompting and positioning system, comprising a device, a user, and a server. The device and user are connected to the server via wireless communication and network, respectively. The three work together to form a prompting and positioning system to realize the positioning prompting and full-process management of materials.

[0006] The device is a low-power Bluetooth beacon, available in two sizes: M (small size) and F (high volume). The beacon's casing has a QR code or barcode for identification and integrates a speaker, buzzer, high-brightness LED indicator, battery, and Bluetooth communication module. The F-type speaker has a volume of ≥90 decibels, suitable for high-noise factory environments. The user terminal is a universal WeChat mini-program, requiring no dedicated application installation. It supports iOS, Android, and Huawei HarmonyOS systems and features functions such as barcode scanning for data entry, warehouse entry registration, warehouse exit search, one-click calling, reverse unbinding of devices to work orders, device factory settings and configuration, device testing and data entry, operating environment detection, device power monitoring, one-click power testing, designated unit warehousing, device warehousing detection, remarks entry, and company information binding and display. The server stores device data, binding relationship data, and operation log data, enabling centralized management of Bluetooth beacons, employee access control, and support for multi-terminal synchronous interaction.

[0007] Preferably, the battery assembly uses disposable safety batteries, wherein the F high-volume Bluetooth beacon is equipped with 4 AA disposable batteries, and the M small-size Bluetooth beacon is equipped with 2 CR2450 button batteries. The battery compartment of the F high-volume Bluetooth beacon is provided with a foolproof structure, which physically restricts the batteries to be installed only with the correct polarity.

[0008] Preferably, the location alert system supports three operating modes: independent operation mode, ERP / management system supplement mode, and ERP / management system collaboration mode. The independent operation mode does not rely on ERP / management systems and independently completes the entire process of material entry registration, exit retrieval, and equipment unbinding via a WeChat mini-program, with all data stored on the server. The ERP / management system supplement mode is compatible with factories that have already deployed ERP / management systems. The binding relationship between Bluetooth beacon numbers and work orders or material numbers is entered into the ERP / management system, and employees can use the WeChat mini-program to enter the beacon number for one-click calling, achieving material location alerts without requiring system intervention. The interface is designed for collaboration with ERP and other management systems. It adapts to factories that have already deployed ERP or other management systems. Users can scan and input work order QR codes or barcodes / material QR codes or barcodes generated by the ERP or other management systems via a WeChat mini-program. This data is then combined with low-power Bluetooth beacon QR codes or barcodes to complete the binding process. Employees can then scan the work order / material QR code or barcode to activate the beacon for audio-visual location alerts. This enables deep collaboration with ERP and other management systems, simplifies binding and search operations, and quickly achieves closed-loop management of the entire business process. It provides multi-mode adaptation solutions to meet the needs of factories with different ERP deployments, achieving material location alerts without complex modifications.

[0009] Preferably, the WeChat mini program's QR code scanning function supports scanning work order or material QR codes or barcodes, as well as Bluetooth beacon QR codes or barcodes, simplifying information entry operations, reducing manual input errors, and improving operational convenience and efficiency.

[0010] Preferably, the client has a device power detection function, which can realize one-click power inspection of all low power Bluetooth beacons through WeChat mini program, display a list of low power devices and push low power warning messages, monitor the power status of beacons in real time, remind maintenance in a timely manner, and ensure the continuous and stable operation of the system.

[0011] Preferably, the prompting and positioning system supports flexible binding relationships, including one-to-many binding and many-to-one binding. One-to-many binding means that the same work order or material code corresponds to multiple low-power Bluetooth beacons, while many-to-one binding means that multiple work orders share one low-power Bluetooth beacon. This can reduce the number of beacons used by 30%-50%, optimize the beacon binding method, reduce the cost of beacon procurement and use, and improve resource utilization.

[0012] Preferably, the positioning system supports a first-in, first-out (FIFO) rule, automatically recording the entry time when materials are put into storage, and displaying them in sorted order by entry time when searching for materials leaving the warehouse, prioritizing the earliest batches. It also supports intelligent recycling of equipment, and beacons can be automatically reused in the case of serial number work orders. After frequently used materials are consumed, the binding information can be cleared through the reverse unbinding function of the equipment to eliminate "ghost positioning", standardize the material requisition order, realize the recycling of beacons, avoid positioning errors, and improve the rationality of inventory management.

[0013] Preferably, the data interaction of the prompting and positioning system is secure and controllable. In the independent operation mode, it does not record sensitive data. In the supplementary mode of ERP and other management systems, it only realizes beacon number calling. In the collaborative mode of ERP and other management systems, it only reads plaintext identifiers such as work order number and material number, without touching sensitive business data of the enterprise. This is used to ensure enterprise data security, avoid leakage of sensitive information, and adapt to enterprise data management specifications.

[0014] Preferably, the server has centralized management functions, which can perform unit management, employee permission authorization, Bluetooth beacon management, batch configuration and operation log query through the backend management platform. When an employee leaves the company, the association binding with the factory can be removed. This is used to achieve centralized system control, standardize employee operation permissions, facilitate traceability management, and ensure the security of system use.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The system supports three operating modes: independent operation, supplementary operation of ERP and other management systems, and collaborative operation of ERP and other management systems. It can be switched according to the actual management situation of the factory without hardware modification: small factories without ERP and other management systems can adopt the independent operation mode; factories with ERP and other management systems that want to maintain system independence can adopt the supplementary operation mode of ERP and other systems, and collaborative operation can be achieved without complex interface development; factories with ERP and other management systems that need refined management can adopt the collaborative operation mode of ERP and other systems to achieve closed-loop management of work orders and materials throughout the entire process. The three modes provide adaptation solutions for factories of different sizes and management levels.

[0017] (2) Two types of Bluetooth beacons are set on the device side: M small size type and F high volume type. The beacons can be flexibly selected according to the different sizes of materials in the factory, the degree of dispersion and concentration of materials, and the storage scenario. The F high volume type Bluetooth beacon is suitable for large pallets, heavy materials and other large-volume prompting and positioning scenarios. With the foolproof battery compartment design, it is safer to use. The M small size type Bluetooth beacon is small in size and suitable for densely placed scenarios such as small parts and light materials. The two types of beacons cover the prompting and positioning needs of all types of materials in the factory and improve the actual adaptability of the system.

[0018] (3) The user end adopts the general WeChat mini program development, which is compatible with mainstream mobile operating systems. There is no need to install a special APP. Operators can complete all operations using their existing smartphones, reducing hardware procurement and personnel training costs. The system does not require the deployment of dedicated readers, gateways, transmitters and other hardware. All functions can be realized through Bluetooth beacons and smartphones, greatly reducing hardware investment costs. At the same time, the mini program supports QR code scanning and input functions, replacing traditional manual input, simplifying the operation process and improving the convenience of operation.

[0019] (4) All battery components on the device end use disposable safety batteries that meet national standards and have no charging function, which completely eliminates the safety risks of explosion and fire of rechargeable batteries in flammable material factory environments; the F-type high volume Bluetooth beacon battery compartment adopts a foolproof structure design, which restricts the battery installation direction through physical structure to avoid equipment damage or short circuit caused by reverse battery connection.

[0024] Figure 5 This is a flowchart illustrating the three operating modes of the present invention. Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0027] This invention provides, for example Figure 1-5 The present invention discloses a Bluetooth beacon-based audio-visual positioning system, characterized in that it includes a device terminal, a user terminal, and a server terminal. The device terminal and the user terminal are wirelessly connected to the server terminal, and the three work together to form a positioning system to realize the positioning prompts and full-process management of materials.

[0028] The device is a low-power Bluetooth beacon, which comes in two specifications: F (high volume) and M (small size). Both specifications have a one-piece molded shell. The shell of the low-power Bluetooth beacon is equipped with a unique QR code or barcode. It integrates a speaker, buzzer, high-brightness LED indicator, battery pack and Bluetooth communication module. The high-volume speaker has a volume of ≥90 decibels, which is suitable for high-noise factory environments.

[0029] The user terminal is a general WeChat mini program, which does not require the installation of a dedicated application. It supports iOS, Android and Huawei HarmonyOS systems and has functions such as scanning and data entry, warehouse entry registration, warehouse exit search, one-click call, reverse unbinding of equipment to work orders, equipment factory settings, equipment testing and data entry, operating environment detection, equipment power monitoring, one-click power test, designated unit warehousing, equipment warehousing detection, remarks information entry, and company information binding and display.

[0030] The server is used to store device data, unit management, binding relationship data, and operation log data, enabling centralized control of Bluetooth beacons, employee permission management, and support for multi-terminal synchronous interaction.

[0031] The battery assembly uses disposable safety batteries. The F-type high-volume Bluetooth beacon is equipped with 4 AA disposable batteries, and the M-type small-size Bluetooth beacon is equipped with 2 CR2450 button batteries. The battery compartment of the F-type high-volume Bluetooth beacon is equipped with a foolproof structure, which physically restricts the batteries to be installed only with the correct polarity.

[0032] The positioning system supports three operating modes: independent operating mode, supplementary mode for ERP and other management systems, and collaborative mode for ERP and other management systems.

[0033] The independent operation mode does not rely on the ERP management system. It can independently complete the entire process of material entry registration, exit search, and unbinding of equipment and work orders through WeChat mini program, and all data is stored on the server.

[0034] The supplementary mode for ERP and other management systems is compatible with factories that have already deployed ERP and other management systems. The binding relationship between Bluetooth beacon numbers and work orders is entered through the computer terminal of the ERP and other management systems. Employees can use WeChat mini-program to enter the beacon number and make a one-click call to achieve material location without the need for system interface integration.

[0035] The collaborative mode of the ERP and other management systems is compatible with factories that have deployed ERP and other management systems. By scanning the QR code of the work order or material generated by the ERP and other management systems through WeChat mini program, and combining it with the low-power Bluetooth beacon QR code to complete the binding, employees can call the beacon to achieve location by scanning the QR code of the work order or material, thus realizing full-process business collaboration.

[0036] The WeChat mini program's QR code scanning function supports scanning work orders, material QR codes or barcodes, and Bluetooth beacon QR codes or barcodes.

[0037] The client has a power monitoring function, which can realize one-click power inspection of all low power Bluetooth beacons through WeChat mini program, display a list of low power devices and push low power warning messages.

[0038] The positioning system supports flexible binding relationships, including one-to-many binding and many-to-one binding. One-to-many binding means that the same work order or material code corresponds to multiple low-power Bluetooth beacons, while many-to-one binding means that multiple work orders share one low-power Bluetooth beacon, which can reduce the number of beacons used by 30%-50%.

[0039] The positioning system supports the first-in, first-out (FIFO) rule. When materials are put into storage, the storage time is automatically recorded. When searching for materials out of storage, the system displays them in sorted order by storage time and prioritizes the earliest batch. It also supports intelligent recycling of equipment. In the case of serial number work orders, beacons can be automatically reused. After commonly used materials are consumed, the binding information can be cleared through the reverse unbinding function of the equipment to eliminate "ghost positioning".

[0040] The data interaction of the positioning system is secure and controllable. In independent operation mode, it does not record sensitive data. In supplementary mode of ERP and other management systems, it only realizes beacon number calling. In collaborative mode of ERP and other management systems, it only reads plaintext identifiers such as work order number and material number, and does not access sensitive business data of enterprises.

[0041] The server has centralized management functions, which can be used to manage and authorize units, authorize employee permissions, manage Bluetooth beacons, perform batch configuration and query operation logs through the backend management platform, and unbind employees from the factory when they leave the company.

[0042] This Bluetooth beacon-based audio-visual positioning system supports three operating modes, namely as follows: Figure 2 As shown, the stand-alone operation mode is suitable for factories without ERP or other management systems (such as hardware manufacturing plants).

[0043] 1. Scene Background

[0044] For example, a small and medium-sized hardware manufacturing plant has no digital management system. Its main business is processing stainless steel pipes, stainless steel plates and other materials. The specifications of the materials are numerous (such as stainless steel pipes 60*0.2, 80*0.3, 10*0.5, etc., with various diameters and thicknesses). Warehouse management relies entirely on manual labor. Employees frequently pick up materials in a chaotic manner and find the wrong materials. The product scrap rate caused by incorrect materials is as high as 15%, and the failure to find materials in a timely manner often causes the production line to stop.

[0045] 1.1 System Deployment

[0046] Bluetooth beacon selection: Based on the characteristics of the factory's materials, heavy-duty stainless steel pipe pallets are selected using F-type high-volume Bluetooth beacons (80mm×50mm×20mm), while light-duty stainless steel plates are selected using M-type small-size Bluetooth beacons (40mm×30mm×10mm). All beacons are initialized by the manufacturer, who binds the beacon's QR code to the device's MAC address and assigns permissions to the hardware manufacturing plant to ensure that the plant has exclusive rights to use the beacons. Other factories cannot use this batch of beacons through the mini-program.

[0047] Employee permission configuration: Factory managers log in to the server-side management platform through the backend to generate employee login accounts and passwords. After logging into the mini-program, employees can configure permissions in a hierarchical manner: Warehouse staff are assigned permissions for warehouse entry registration, warehouse exit search, reverse unbinding of equipment work orders, equipment power detection, and entry of remarks information; ordinary production line employees are only assigned permissions for warehouse exit search and one-click call; managers are assigned super administrator permissions, which can view all operation logs and adjust employee permissions.

[0048] Mini Program Binding: After employees enter the mini program by searching for its name on WeChat, they first log in with their basic WeChat information, then enter their assigned account and password to complete the binding with their organization. After the administrator reviews and confirms the relevant information through the backend, and authorizes the employee to use the relevant mini program functions, the employee completes the actual login. After logging in, the mini program only displays the functional modules with the corresponding permissions, and modules without permissions are hidden to avoid accidental operation.

[0049] Detailed operating procedures:

[0050] Material Inbound Registration: When stainless steel pipes with specifications of 60*0.2 (diameter 6CM, thickness 0.2MM) enter the warehouse, the warehouse staff will fix a basic Bluetooth beacon (number F00300) in a conspicuous position on the material pallet, open the inbound registration function of the WeChat mini program, manually enter the material work order number "6*0.2", and use the mini program to call the mobile phone camera to scan the QR code or barcode on the F00300 beacon to complete the beacon number entry; at the same time, "supplier XX, quality inspection qualified" can be entered in the remarks information field. After confirming all the information, click submit, and the server will immediately store the binding relationship between the work order number and the F00300 beacon, and automatically record the inbound time.

[0051] Material Outbound Search: After receiving the production instruction to process 6*0.2 stainless steel pipes, production line employees open the outbound search function of the WeChat mini-program, enter the material work order number "6*0.2" in the search bar, and click search. The mini-program retrieves the corresponding beacon number F00300 through the server, and displays the material's remarks and the real-time battery level of the F00300 beacon (e.g., 85%). An "Instant Search" button is displayed on the right side of the page. When the employee clicks this button, the mini-program scans and connects to the F00300 beacon (within the communication range) via Bluetooth. Upon receiving the instruction, the beacon immediately emits a beeping sound, and the LED indicator flashes at a frequency of 2 times per second. Based on the audio-visual prompts, the employee can quickly find the corresponding material.

[0052] Equipment reverse unbinding of work orders: When all 6*0.2 stainless steel pipes are used up, warehouse staff can use the equipment reverse unbinding function on the WeChat mini-program to scan and enter the beacon QR code or barcode of the used material, enter FOO300, and click unbind. The server will immediately clear the binding relationship between the F00300 beacon and the work order number. When new 6*0.2 material of the same specification enters the warehouse, the warehouse staff will normally enter and bind a new random beacon number. When a colleague searches for the material work order number "6*0.2", the displayed locator will be the new number, and the beacon F00300 will no longer be found (the material has been used up). All beacons can be reused after use.

[0053] Device Battery Detection and Maintenance: Warehouse staff can use the device battery detection function in the mini-program to check the battery status of all Bluetooth beacons at any time. The list displays devices with low battery (≤5%) and devices with normal battery. When a beacon's battery is detected to be ≤5%, a low battery warning message is automatically pushed to the warehouse staff, prompting them to replace the batteries in time. For F-type high-volume beacons, replace with 4 AA disposable alkaline batteries; for M-type small-size beacons, replace with 2 CR2450 button batteries. After replacement, the mini-program automatically updates the beacon's battery status to ensure normal system operation.

[0054] like Figure 3 As shown, this is a supplementary model for ERP and other management systems (suitable for printing and packaging factories that have ERP and other management systems but need to maintain system independence).

[0055] 2. Scene Background

[0056] A medium-sized printing and packaging factory has deployed a mature ERP management system, which has realized the digital management of orders, work orders, and inventory. The factory mainly produces various packaging cartons and printing paper, with more than 300 paper specifications. Each order corresponds to a unique work order number (such as WS25075, WS25076). However, ERP and other management systems can only record the quantity of materials in stock and cannot realize the physical location of materials. After receiving the goods, the warehouse staff randomly places the materials. When employees look for materials, they need to confirm the inventory through the ERP and other management systems and then manually search the warehouse. The average time to find materials is about 20 minutes. Moreover, the warehouse staff receive a large amount of materials and are under time pressure, so they do not have extra time to perform complex system binding operations. There is an urgent need for a positioning system that can supplement ERP and other management systems and does not require interface development.

[0057] 2.1 System Deployment

[0058] Bluetooth beacon selection: The factory materials are all paper pallets, which are large in size and need to be stored for a long time. We uniformly select F-type high-volume Bluetooth beacons. All beacons have been initialized by the manufacturer and bound to the factory's permissions before leaving the factory to ensure unique usage rights.

[0059] Employee permission configuration: Permissions are configured through the server-side management platform. Warehouse staff are assigned permissions for beacon placement and power consumption inspection; production line staff are assigned permissions for one-click calling via the mini-program; and management personnel are assigned permissions to view operation logs. There is no need to assign mini-program entry registration permissions to warehouse staff, which adapts to the work rhythm of factory warehouse staff.

[0060] ERP and other management system adaptation: No modifications are required to the existing ERP and other management systems in the factory, and no data interfaces need to be developed. Only a "Bluetooth beacon number" field is added to the work order remarks column of the ERP and other management systems, which is used by warehouse staff to enter the beacon number, to achieve lightweight collaboration between the ERP and other management systems and this positioning system.

[0061] Detailed operating procedures

[0062] Material receiving and beacon binding: When printed paper with work order number WS25075 arrives at the warehouse, the warehouse staff places the material pallets in the warehouse according to the work order, places one basic Bluetooth beacon (number F00300) on each pallet, and records the beacon number F00300 by hand on the delivery note; after all receiving work is completed, the warehouse staff uses the factory's ERP and other management systems to query the material information corresponding to work order number WS25075, enters F00300 in the "Bluetooth Beacon Number" field of the work order remarks column in the ERP and other management systems, and completes the binding between the ERP and other management systems and the beacon. The whole process does not require operating the applet and is adapted to the work habits of warehouse staff.

[0063] Material Outbound Locator: When production line employees produce an order up to work order number WS25075, they need to locate the corresponding printing paper. First, they query the remarks information of the work order through the factory's ERP and other management systems to obtain the corresponding Bluetooth beacon number F00300. Then, they open the one-click call function of the WeChat mini program, enter the beacon number F00300 in the input field, and click call. The mini program connects to the F00300 beacon via Bluetooth Low Energy. The beacon immediately emits a beeping sound, and at the same time, the LED indicator flashes at a frequency of 2 times per second. Employees can quickly locate the material based on the sound and light prompts and complete the search quickly.

[0064] Equipment Management and Maintenance: Managers can view all colleague entry and exit registration records and one-click call operation logs through the server-side backend management platform, tracing the operator, operation time, and beacon number used for the call. Warehouse staff can perform one-click power checks through the mini-program at any time, promptly replacing batteries of low-power beacons to ensure continuous and stable system operation. When the materials in the WS25075 work order are consumed, warehouse staff can remove the F00300 beacon from the pallet and bind it to a new work order, realizing the cyclical use of the beacon.

[0065] like Figure 4As shown, this is a collaborative mode for ERP and other management systems (suitable for printing and packaging factories that have ERP and other management systems and require refined management).

[0066] 3. Scene Background

[0067] A medium-sized printing and packaging factory has deployed an ERP management system, which can generate work orders with unique QR codes (the QR code contains plain text information such as work order number and material specifications). The factory has high requirements for refined production management and needs to achieve closed-loop management of the entire process from work order issuance, material warehousing, material retrieval, and production processing. At the same time, it hopes to reduce manual data entry and lower the data error rate. Therefore, it urgently needs a positioning system that can deeply integrate with ERP and other management systems and support barcode scanning.

[0068] 3.1 System Deployment

[0069] Bluetooth beacon selection: Factory materials include printing paper, packaging accessories, printing ink, etc. The printing paper pallet uses F-type high-volume Bluetooth beacon, while the small materials such as packaging accessories and printing ink use M-type small-size Bluetooth beacon. All beacons have been initialized by the manufacturer and bound to factory permissions before leaving the factory.

[0070] Employee permission configuration: Fine-grained permission configuration is achieved through the server-side management platform. Warehouse staff are assigned permissions for inbound registration, outbound search, reverse unbinding of equipment to work orders, equipment power detection, and entry of remarks; production line staff are assigned outbound search permissions; and management personnel are assigned super administrator permissions, which allow them to view the entire process operation log, adjust employee permissions, and perform data statistical analysis.

[0071] Lightweight adaptation to ERP and other management systems: No need to develop core interfaces for ERP and other management systems. Only plaintext data (work order number, material specifications) of work order QR codes are exported from ERP and other management systems. This ensures that the mini-program can recognize the work order information after scanning the code, realizes deep collaboration between ERP and other management systems and this prompt positioning system, and does not access sensitive data in ERP and other management systems (such as material costs, supplier contracts, and inventory balances).

[0072] Detailed operating procedures

[0073] Material receiving and barcode scanning binding: When printed paper with work order number WS25075 arrives at the warehouse, the warehouse staff fixes the high-volume Bluetooth beacon (number F00300) to the material pallet, opens the warehouse registration function of the WeChat mini program, clicks on material work order barcode scanning and enters the information, and uses the mobile phone camera to scan the QR code of work order WS25075 generated by the ERP and other management systems. The mini program automatically recognizes and records the work order number WS25075. Then, the staff clicks on positioning device barcode scanning and enters the information, scans the QR code on the F00300 beacon, completes the beacon number entry, confirms the information and clicks submit. The server immediately stores the binding relationship between the work order and the beacon, automatically records the receiving time, and synchronizes the work order information with the ERP and other management systems. The whole process does not require manual entry of the work order number, and the data error rate is 0.

[0074] Material Outbound Search: When production line employees reach work order WS25075, they can open the outbound search function of the WeChat mini-program, click on "Material Work Order Scan Search," scan the QR code of work order WS25075, and the mini-program will quickly query the corresponding beacon number F00300 through the server. At the same time, it will display the material remarks, the beacon's real-time battery level (90%), and the time of entry into the warehouse. The page will display an "Instant Call Search" button. When the employee clicks this button, the mini-program will connect to the F00300 beacon via Bluetooth Low Energy. The beacon will emit a beeping sound, and the LED indicator will flash at a frequency of 2 times / second. The employee can quickly find the material based on the sound and light prompts, realizing a closed loop of the entire process from work order scanning to material search.

[0075] First-In-First-Out (FIFO) rule application: When multiple work orders and multiple batches of the same material specification (such as the same model of ink) are received into the warehouse, the server automatically records the entry time of each batch. When employees search for the material, the mini-program displays all the corresponding beacon numbers in order of entry time from earliest to latest, and prioritizes recommending the earliest batch. Employees can click to call the beacon of the earliest batch, realizing the FIFO issuance of materials, avoiding the expiration of materials due to prolonged storage, and improving inventory turnover.

[0076] End-to-end management and traceability: Managers can view all material entry registration, exit search, and reverse unbinding operation logs through the server-side backend management platform, achieving full traceability of operations; at the same time, the platform can collect data such as beacon usage frequency, material search times, and inventory turnover time, providing data support for factory production management, and beacons can be reused for new work orders.

[0077] The above three embodiments correspond to the three operating modes of the present invention, and are all based on the collaborative design of the device end (F large volume type / M small size type Bluetooth beacon), user end (WeChat mini program), and server end (cloud / local deployment). The operation process and permission configuration are adjusted only according to whether the factory has an ERP or other management system and different management needs. No modification to the system hardware is required.
