[0002] Currently, in the manufacturing industry, the picking and stocking operations of work objects (parts) play a vital role and directly affect the efficiency and cost of the production line.

[0003] In related technologies, stocking and picking operations primarily rely on paper labels and stocking lists. In these situations, workers need to constantly monitor changes in component information, manually update this information, and then print and affix new paper labels. This operation consumes significant man-hours, significantly increasing the workload of technicians, especially when components are frequently updated and the amount of information required is enormous. Furthermore, when workers perform picking operations on work objects, they must quickly locate and select the correct part based on the information on the stocking list. This process tests their experience, memory, and familiarity with the workstation layout.

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] According to an embodiment of the present invention, an embodiment of a method for picking work objects is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 1 is a flow chart of a method for picking a work object according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0033] Step S102: obtaining quantity information of target objects to be picked, and setting light prompt information of the electronic tag based on the quantity information.

[0034] In the technical solution provided in step S102 of the present invention, electronic tags are deployed at the work locations where the work objects are placed, and the electronic tags correspond to the work objects one by one. The number of types of light prompt information is the same as the quantity information.

[0035] Optionally, electronic tags, a core technology component in embodiments of the present invention, can be deployed at the workstation of each object requiring picking, forming a one-to-one relationship with that specific object. These tags not only display relevant information about the object, such as name, quantity, and location, but more importantly, dynamically change their display based on system instructions. For example, they illuminate different colored indicators to guide picking operations and provide buttons for operators to confirm the completion of picking, thereby enabling automated management of picking tasks and efficient execution of workflows.

[0036] Alternatively, a work object can refer to items that need to be picked in the logistics field, that is, goods awaiting picking. In automotive logistics scenarios, work objects specifically refer to various parts, such as engine parts and body parts. The diversity and frequent fluctuations in the number of work objects are the root causes of the complexity of picking operations. Therefore, timely and accurate information display and guidance on work objects are key to improving picking efficiency.

[0037] Optionally, in this embodiment of the present invention, a target object refers to a person or tool responsible for performing a picking operation, such as a worker (picking and stocking personnel) or a vehicle used to load and transport picked items. Based on the number of target objects, the electronic tag's light prompt information is set to ensure that each target object (worker or vehicle) receives clear and unambiguous task instructions, thereby avoiding confusion and errors during operations.

[0038] Optionally, light cues are a key way for electronic tags to indicate tasks to target objects. By illuminating a specific color indicator, picking instructions can be issued to workers or vehicles. This color coding method allows multiple target objects to quickly identify their tasks when performing picking tasks simultaneously, without interfering with the operations of other objects. The number of light cue types is the same as the number of target objects, ensuring that each target object has a unique task identifier, thereby improving the accuracy and efficiency of the picking process.

[0039] In this embodiment, the quantity information of the target objects used to perform a picking operation on the work object can be obtained, and the same number of light prompt information types as the quantity information can be set for the electronic tag.

[0040] Optionally, the number of target objects required for a picking task can be determined. Data can be exchanged with upstream management or distribution systems to obtain the target objects involved in a specific picking task and the number of objects each requires to be picked. This information is generated based on current picking requirements and the work plan, and is updated in real time via the network or internal interfaces, ensuring the accuracy and timeliness of picking instructions.

[0041] Optionally, once the number of target objects is known, it can be converted into specific lighting cues. This process can involve two aspects: first, determining the lighting color or pattern of the electronic tag to distinguish different picking tasks; second, setting the display logic of the electronic tag to ensure that each task is appropriately indicated.

[0042] Optionally, the electronic tags can be assigned different colors or flashing patterns based on the number of target objects, serving as visual indicators for picking tasks. For example, if there are four target objects, red, yellow, blue, and green could be assigned to each target object. This ensures that each target object has its own unique color code, making it easier to quickly identify in a busy picking environment.

[0043] Optionally, the electronic tag's display logic needs to closely match the target object's quantity information. This means that for each target object, the electronic tag should display not only its corresponding light color but also the number of workpieces that need to be picked for that object. For example, if target object A requires 10 parts to be picked, the electronic tag corresponding to A will light red and display the message "Pick Quantity: 10" on the screen. This display logic ensures that operators can intuitively understand their tasks without having to refer to additional paper or electronic documents.

[0044] It's important to note that this entire setup process is dynamic. As the picking task progresses, the electronic tag's lighting and display will be continuously updated to adapt to changes in the workflow. For example, when a target object completes its picking task and is confirmed, the corresponding electronic tag's light will turn off, and the picking instructions for the next target object will be adjusted simultaneously, ensuring seamless and efficient picking operations.

[0045] The key to this method in this embodiment of the present invention lies in transforming abstract quantity information into intuitive visual indications. Furthermore, through automated control of electronic tags, this method significantly simplifies the picking process and improves the speed and accuracy of task completion. This demonstrates the core of this embodiment of the present invention, which is to utilize electronic information technology to improve traditional logistics operations, achieving more efficient and intelligent picking and stocking operations.

[0046] Step S104 : in response to detecting a picking task of a work object, controlling the electronic tag to at least display light prompt information and picking quantity information.

[0047] In the technical solution provided in step S104 of the present invention, the picking task can be used to indicate the picking operation to be performed. The picking quantity information is used to indicate the number of work objects to be picked, which can also be called the picking quantity.

[0048] In this embodiment, after the light prompt information of the electronic tag is set based on the quantity information of the target object, if a picking task of the work object is detected, the electronic tag can be controlled to display at least the light prompt information and the picking quantity information.

[0049] Optionally, the picking system for work objects in embodiments of the present invention is capable of real-time detection of picking task triggers. These task triggers can originate from a variety of sources, including but not limited to updates to the order system, changes to the inventory management system, and adjustments to the production schedule. Once a new picking task is detected, the picking system can respond quickly to ensure a timely and efficient picking process.

[0050] For example, when a new order is received from a customer, the system automatically generates a picking task based on the parts list and quantity in the order. If the inventory management system detects that the stock level of a specific part falls below a preset threshold, the system automatically triggers a picking task to replenish the stock. Depending on changes in the production plan, the system may need to adjust the picking order or quantity of parts to ensure smooth operation of the production line.

[0051] Optionally, after responding to a picking task, the electronic tag may be controlled to display necessary task information, including but not limited to light prompt information and picking quantity information.

[0052] For example, a picking system can transmit picking task information to corresponding electronic tags via wireless communication methods (such as 2.4GHz proprietary protocols or Bluetooth). This transmission process requires the system to have stable and fast communication capabilities to ensure that the information is delivered immediately.

[0053] Optionally, for lighting prompt information, the lighting color or pattern code corresponding to each target object (operator or pick-up cart) in the picking task can be sent to the electronic tag. After parsing this information, the electronic tag lights up the corresponding indicator light to guide the target object to pick. The choice of lighting color or pattern should ensure visual distinction between different target objects to avoid confusion. For picking quantity information, the display screen of the electronic tag can show the specific number of work objects that the target object needs to pick. The display of the picking quantity information ensures that the operator or pick-up cart operator is clear about the scale and scope of the picking task, avoiding errors in the picking quantity.

[0054] Optionally, the electronic tag's display control logic is adjusted based on the real-time status of the picking task, encompassing the following key aspects: At the start of a picking task, the electronic tag displays the corresponding light prompt and picking quantity based on the sent picking task information, informing the target object of the start of the task. After the operator or cart completes a portion of the picking, the electronic tag receives feedback and updates the display status, specifically the quantity information or adjusts the light prompt to reflect the progress of the picking task. When the target object completes the entire picking task and the electronic tag receives a confirmation signal, it turns off the corresponding indicator light and stops displaying the picking quantity information, preparing for the next task or target object.

[0055] In this embodiment of the present invention, the control logic in the above-described method ensures dynamic management and real-time guidance of picking tasks, significantly improving the accuracy and efficiency of picking operations. The instant feedback mechanism of electronic tags provides real-time information on the execution of picking tasks, thereby optimizing task allocation and scheduling, reducing waiting time, and avoiding picking errors, ultimately achieving intelligent and automated picking processes.

[0056] Step S106 , controlling the target object corresponding to the type of the light prompt information, and performing a picking operation on the working object that meets the picking quantity information at the working position.

[0057] In the technical solution of the above-mentioned step S106 of the present invention, after controlling the electronic tag to display at least the light prompt information and the picking quantity information, the target object corresponding to the type of the light prompt information can be controlled, and the picking operation can be performed on the work object that meets the picking quantity information.

[0058] Optionally, the type of lighting information can be customized based on the target object, ensuring targeted and efficient picking operations. To achieve this, each target object is assigned a unique lighting color. This color-coding mechanism helps operators quickly identify their picking tasks among numerous electronic tags. For example, target object A could be assigned a red light, while target object B could be assigned a blue light.

[0059] It should be noted that the encoding methods described in the embodiments of the present invention are not limited to color and can be expanded to include patterns, flashing frequencies, and other forms to accommodate more complex and diverse picking environments. Any method that can use electronic tags to provide targeted prompts for different target objects falls within the scope of protection of the embodiments of the present invention.

[0060] Optionally, once the target has identified their picking task and confirmed the location of the task using the light prompt information on the electronic tag, the next step is to execute the picking operation until the picking quantity information displayed on the electronic tag is met. The above process emphasizes the standard and automated confirmation mechanism for task completion.

[0061] Optionally, operators or trolleys go to designated work locations to pick items based on the light prompts and picking quantity information displayed on the electronic tag. Light prompts ensure the accuracy of picking operations, while quantity information specifies the scale of each pick. After completing the picking, operators or trolleys press the confirmation button on the electronic tag, and the system can instantly receive the above feedback information to confirm the completion status of the picking task. The electronic tag will then update the displayed information, including adjusting the light prompts and updating the picking quantity (reducing the number picked or displaying the number of the next task), to ensure the orderly progress of the picking operation and the effective management of the task.

[0062] Optionally, throughout the picking process, the system continuously monitors and responds to activity at the workstation, adjusting the electronic tag display based on the target object's movements to maintain efficient picking. For example, when a target object completes its picking task, the system immediately releases the workstation and updates the electronic tag display to prepare for the arrival of the next target object or task, thus achieving seamless picking operations.

[0063] In an embodiment of the present invention, the control mechanism in the above method fully utilizes the dynamic display characteristics and interactive functions of the electronic tag, providing operators with clear operating instructions and immediate task confirmation, greatly improving the accuracy and efficiency of picking operations, while also reducing the frequency of manual intervention and reducing the risk of picking errors.

[0064] In the above-mentioned steps S102 to S106 of the embodiment of the present invention, corresponding electronic tags can be deployed in advance for the work positions of different work objects. If it is necessary to pick the work object, the quantity information of the target objects to be picked can be obtained, and the types of light prompt information of the corresponding number can be set for the electronic tag based on the quantity information, that is, one type of light prompt information corresponds to one target object. If a picking task for the work object is detected, the electronic tag can be controlled to secretly display the corresponding light prompt information and picking quantity information for the picking task. The target object corresponding to the type of light prompt information can be controlled to perform a picking operation on the work object at the corresponding work position, and the number of work objects to be picked must meet the picking quantity information. In this embodiment, through the dynamic prompt and feedback mechanism of the electronic tag, combined with the precise picking quantity information, the accuracy and speed of picking the work objects are effectively improved, overcoming the limitations of slow information update, waste of resources and high proficiency requirements of operators in related technologies, thereby significantly improving the picking efficiency and reducing potential picking errors and rework costs, thereby achieving the technical effect of improving the picking efficiency of work objects and solving the technical problem of low picking efficiency of work objects.

[0065] The above method of this embodiment is further introduced below.

[0066] As an optional embodiment, the method is applied to a picking system for work objects, the picking system includes an electronic tag, a base station, a tag system and an upstream system, the method also includes: controlling the upstream system to send a picking task to the electronic tag via the tag system and the base station; step S104, in response to detecting the picking task of the work object, controlling the electronic tag to at least display light prompt information and picking quantity information, including: in response to the electronic tag detecting the picking task, and the number of work objects to be picked is multiple, obtaining the picking order of the work objects and / or the type information of the work objects to be picked; determining the display strategy of the electronic tag according to the picking order and / or type information, and controlling the electronic tag to display at least light prompt information and picking quantity information according to the display strategy, wherein the display strategy is used to represent the rules for the electronic tag to display light prompt information and picking quantity information.

[0067] In this embodiment, the upstream system is responsible for integrating order information, inventory data, production plans, etc., generating specific picking tasks and transmitting them to the picking system. The upstream system uses the intermediary role of the labeling system to wirelessly transmit the picking task information (including the type, quantity, picking order, etc. of the work object) to the corresponding electronic tag via the base station. This process ensures the immediate issuance of picking tasks and the accuracy of information. The upstream system automatically or semi-automatically generates a picking task list based on real-time logistics needs and inventory status. Each task entry contains detailed information on the work object to be picked. The generated picking tasks can be assigned to specific work locations and target objects, and transmitted electronically to the relevant electronic tags through the interface of the labeling system.

[0068] Optionally, when the electronic tag detects a picking task forwarded by the upstream system via the base station, it can enter a response mode. The key point of the above steps is how to formulate and implement an effective display strategy based on the picking order and type information of the work object to guide the picking operation of the target object.

[0069] Optionally, information about the order and / or type of objects to be picked is extracted from the picking task. This serves as the basis for developing a display strategy. Based on this information, a display strategy is generated to determine when to illuminate which type of light and how to present the picked quantity information on the electronic tag's display. This strategy should take into account operational efficiency, error prevention principles, and operator convenience.

[0070] Optionally, based on the order and type of picking, the electronic tag will be controlled to illuminate corresponding indicators according to a pre-defined strategy, using color or flashing patterns to encode different work objects or picking stages. Simultaneously, the electronic tag display will clearly display the target quantity for each picking operation according to the display strategy, helping operators quickly understand the scale of their tasks.

[0071] In the embodiment of the present invention, the efficient operation of the entire picking process relies on seamless coordination and communication between the upstream system, the tag system, the base station and the electronic tag. The upstream system is responsible for the generation of tasks and the transmission of initial information, the tag system and the base station act as the intermediate transfer of information, and the electronic tag is the front-end interface for task execution, directly interacting with the operator or equipment to provide task guidance and feedback reception. During the picking operation, the information flow is not only a one-way transmission from the upstream system to the electronic tag, but also includes feedback from the electronic tag to the upstream system, such as the picking completion status, operation abnormality reports, etc. This requires that the two-way flow of information be considered when designing the system. Through the implementation of the display strategy, the system can monitor the execution progress of the picking task in real time. Once the task completion or abnormality is detected, it can respond immediately, such as updating the display content of the electronic tag, adjusting the picking order, notifying relevant personnel to intervene, etc.

[0072] In summary, the response mechanism and display strategy described above are core components for achieving intelligent and automated picking systems. They not only improve operational efficiency and reduce errors, but also enhance the system's flexibility and ability to handle complex picking tasks by refining the management of picking sequence and category information.

[0073] As an optional embodiment, the display strategy includes a first display strategy and a second display strategy, the first display strategy is used to indicate the rule that the electronic tag displays at least light prompt information and picking quantity information according to the picking order, and the second display strategy is used to indicate the rule that the electronic tag displays at least light prompt information and picking quantity information according to the type information. The method also includes: predicting the time information corresponding to the first display strategy and the time information corresponding to the second display strategy, wherein the time information is at least used to indicate the time required to transmit the first display strategy or the second display strategy, display the light prompt information and picking quantity information, perform the picking operation, and trigger the picking completion instruction; the display strategy corresponding to the minimum value of the time information of the first display strategy and the time information of the second display strategy is determined as the display strategy of the electronic tag to be controlled.

[0074] In this embodiment, the first display strategy displays at least lighting prompts and pick quantity information according to the picking order. This strategy emphasizes the linear progression of the picking process, guiding picking through a pre-set sequence (e.g., left front → left back → right front → right back), while ensuring that each picking operation has clear instructions (light color, flashing pattern, etc.) and quantity targets. This method is suitable for situations where strict control of the picking order is required to ensure workflow consistency and reduce potential confusion.

[0075] Optionally, the second display strategy displays at least light prompts and picking quantity information based on the type of workpiece. This strategy focuses on category-based guidance, arranging picking tasks based on part or equipment type, ensuring that workpieces of the same type can be quickly identified and picked under similar conditions. This approach is suitable for scenarios where different types of parts or equipment need to be quickly sorted to improve picking efficiency.

[0076] Optionally, to compare and select the display strategy that best suits the current picking task, the time required for each operation under the two display strategies can be pre-estimated. This time information covers the time required to transmit the display strategy, display the light prompt information and picking quantity information, execute the picking operation, and trigger the picking completion instruction.

[0077] Optionally, the time required for information from the first and second display strategies to be transmitted to the electronic tag is evaluated. This includes the communication time from the upstream system through the tag system and base station to the electronic tag, as well as the time required for the electronic tag to receive and decode the display strategy. The time required for the electronic tag to display the light prompt information and the picking quantity information is estimated, as well as the time required for the target object to perform the picking operation, including the time required for specific actions such as locating the part, verifying the quantity, and confirming the pick. The time required for the operator to trigger the picking completion instruction through the electronic tag after completing the picking operation can also be considered, including the button press response time and information upload time.

[0078] Optionally, based on the above-mentioned predicted time information, the overall time consumption of the first display strategy and the second display strategy will be compared, and the strategy with the shortest time consumption or the one closest to the minimum value will be selected as the display strategy for the electronic tag to be controlled. This decision-making process aims to balance picking efficiency and operational smoothness to ensure that the overall performance of the picking system is maximized. Through algorithmic analysis, the time information under the two display strategies is comprehensively considered to determine which strategy can more effectively reduce the total picking time consumption. For example, if the transmission, display and completion instruction triggering time of the first display strategy are shorter than those of the second display strategy, even if the second display strategy may be faster in performing the picking operation, the first display strategy will still be selected because the first display strategy can bring better overall efficiency.

[0079] Optionally, once the most appropriate display strategy is determined, implementation begins immediately. The upstream system generates picking instructions based on the selected strategy and transmits these instructions to the relevant electronic tags via the tagging system and base station. Upon receiving the instructions, the electronic tags adjust their lighting and quantity information according to the display strategy, guiding the target object to begin the picking operation. The target object then performs the picking operation according to the displayed instructions. The system monitors the picking progress, receives feedback on the completion of the picking, and adjusts the display strategy or task instructions as appropriate.

[0080] In the embodiment of the present invention, through the above method, the picking system can dynamically select the display strategy that best suits the current scenario, thereby achieving high efficiency and flexibility in picking operations and effectively responding to the challenges of different types of picking tasks.

[0081] As an optional embodiment, a first display strategy is determined according to the picking order, including: in response to performing a picking operation on at least one work object in the first picking area in the picking order, determining the first display strategy to display at least light prompt information and picking quantity information on at least one electronic tag corresponding to at least one work object in the first picking area; in response to completing the picking operation on at least one work object in the first picking area, determining a second picking area after the first picking area in the picking order, and determining the first display strategy to display at least light prompt information and picking quantity information on at least one electronic tag corresponding to at least one work object in the second picking area.

[0082] In this embodiment, the core of the first display strategy is to control the display of electronic tags according to a preset picking sequence, guiding workers (such as workers or carts) to complete picking tasks in stages. Each picking area is considered a picking stage, and the system determines which electronic tags of the work objects should display light prompts and picking quantity information based on the current picking stage.

[0083] Optionally, when the picking task begins, the first picking area (first picking area) in the picking sequence is determined, and the electronic tags of all work objects in this area are controlled so that they at least display corresponding light prompt information and picking quantity information to prepare for the start of picking. As the picking operation proceeds, the progress of the work in the first picking area is continuously monitored. Once it is detected that at least one work object has completed the picking task (for example, the operator or the box car has completed the picking in this area according to the information on the electronic tag), the system immediately updates the display strategy and turns its attention to the next area (second picking area) in the picking sequence. According to the new display strategy, the electronic tags of the work objects in the second picking area are controlled to display corresponding light prompt information and picking quantity information to guide the work objects into the next stage of picking operations. This process repeats until the tasks in all picking areas are completed.

[0084] Optionally, in response to performing a picking operation on the work object in the first picking area, the main task at this time is to activate the relevant electronic tags in the first picking area to ensure that the work object can be picked accurately according to the displayed light prompts and picking quantities. The above steps mark the official start of the picking activity and are a crucial starting point in the entire picking process. In response to completing the picking operation in the first picking area, that is, once it is detected that the picking task in the first picking area has been completed, the system immediately identifies the next picking area (the second picking area) and adjusts the display strategy so that the work objects in the second picking area receive corresponding picking instructions. This step reflects the picking system's ability to dynamically manage and control the picking process, ensuring the continuity and efficiency of the picking tasks.

[0085] In an embodiment of the present invention, during the implementation of the first display strategy, the display strategy is continuously evaluated and adjusted to adapt to the actual progress of the picking operation. The above-mentioned dynamic response mechanism is conducive to the rational allocation and utilization of resources. For example, by timely updating the display strategy, the system can avoid the waiting time of the work object after completing the task in the current picking area, and immediately enter the next stage of picking, thereby improving the picking efficiency and the satisfaction of the workers. Controlling the display of electronic tags according to the picking order can effectively prevent picking confusion and ensure that each work object is guided to the correct picking area at the right time, thereby avoiding picking errors. In the above manner, the first display strategy not only provides clear and orderly picking guidance for the work object, but also significantly improves the overall operating efficiency of the picking system and the work experience of the work object through refined time management and resource scheduling.

[0086] As an optional implementation method, in response to the existence of a third picking area after the second picking area in the picking sequence, the second picking area is determined as the first picking area, and the third picking area is determined as the second picking area, and the following steps are performed until there is no third picking area in the picking sequence: in response to completing the picking operation on at least one work object in the first picking area, the second picking area after the first picking area in the picking sequence is determined, and the first display strategy is determined to display at least light prompt information and picking quantity information on at least one electronic tag corresponding to at least one work object in the second picking area.

[0087] In this embodiment, the key is that the system can dynamically adjust the focus of picking control. As the picking operation shifts between different areas, the first picking area and the second picking area can be continuously redefined to ensure the consistency and efficiency of the picking process.

[0088] Optionally, at the start of a picking task, the initial picking area is defined as the first picking area based on the picking order, and the subsequent area is defined as the second picking area. When it is detected that the picking operation in the first picking area has been completed, that is, at least one operating object (such as an operator or a box cart) has completed all picking tasks in the area according to the information on the electronic tag, the original second picking area is upgraded to the new first picking area, and the area after the first picking area becomes the new second picking area. The above dynamic adjustment ensures that the picking process transitions smoothly according to the established order.

[0089] Optionally, after completing the dynamic adjustment of the aforementioned zones, the first display strategy is reactivated to guide the worker in performing picking operations within the new first picking zone. This strategy includes controlling the electronic tags of the workers within the new first picking zone to display at least light prompts and picking quantity information to guide the worker in starting a new picking task. The worker's progress in the first picking zone continues to be monitored. Once the system detects that the picking operation in the first picking zone is complete, the system redefines the first and second picking zones, updates the display strategy, and guides the worker to the next stage of picking.

[0090] Optionally, the dynamic execution process continues until there is no longer a third pick zone in the picking sequence. Specifically, when the worker is about to complete the last pick zone, there is no need to redefine the zones or update the display strategy. Instead, the focus is on guiding the worker to complete the remaining sections, ensuring the successful completion of the entire picking task.

[0091] Optionally, after each job in a picking zone is completed, the system checks whether a third picking zone exists. If so, the zone redefinition and display strategy update described above are performed. If not, the current picking zone is the last one, and picking support for the third picking zone will be focused on until all jobs are completed.

[0092] In this embodiment of the present invention, by implementing the aforementioned dynamic zone adjustment and display strategy update steps, the picking system ensures that workpieces are picked at the correct time and location every time, avoiding unnecessary waiting and movement, and improving picking speed and efficiency. Precise zone division and lighting cues reduce the likelihood of picking errors and improve picking accuracy. This adapts to the needs of different picking tasks, especially in changing picking environments, enabling more flexible adjustment of picking strategies to address uncertainty.

[0093] In summary, by dynamically adjusting the picking area and updating the display strategy in a timely manner, intelligent guidance and support are provided for picking operations, greatly improving the efficiency, accuracy and flexibility of logistics picking operations.

[0094] As an optional embodiment, a second display strategy is determined according to the category information, including: in response to performing a picking operation on a work object of the first category in the category information, determining the second display strategy to display at least light prompt information and picking quantity information on the electronic tag corresponding to the work object of the first category; in response to completing the picking operation on the work object of the first category, determining a second category other than the first category in the category information, and determining the second display strategy to display at least light prompt information and picking quantity information on the electronic tag corresponding to the work object of the second category.

[0095] In this embodiment, the second display strategy focuses on controlling the displayed content of the electronic tag based on the type of work object to optimize the picking process. This method is particularly suitable for handling complex picking scenarios with multiple types of work objects, ensuring that each type of work object is correctly guided within the appropriate time.

[0096] Optionally, when a picking task is initiated, a first category of work objects requiring priority are identified based on the category information, such as specific parts for a particular vehicle model or tasks requiring special requirements. In this case, a second display strategy is determined: for the first category of work objects, the corresponding electronic tags should display at least light prompt information and the picked quantity.

[0097] Optionally, workers or equipment perform picking operations on the first category of work objects based on the light prompt information (such as a specific color light) and picking quantity information displayed on the electronic tag. This light prompt information provides clear guidance for workers, ensuring the accuracy and efficiency of the picking process. The operation status is continuously monitored. When it is detected that the picking operation for the first category of work objects has been completed, indicating that the work object has completed all picking requirements according to the instructions on the electronic tag, the next strategy adjustment is made.

[0098] Optionally, once the first category of picking tasks is completed, the category information is re-evaluated to determine the next category of work objects to be processed. This could mean switching from parts for one vehicle model to parts for another, or from one type of equipment to another. The second display strategy is then updated, sending control instructions to the electronic tags corresponding to the second category of work objects, displaying at least the new light prompt and pick quantity information. This means the operator will see the new instructions and prepare for the next round of picking operations.

[0099] Optionally, the above process can be repeated until all categories of work objects in the picking sequence have been processed, that is, the system has traversed all category information. In other words, each time a category is picked, the next category is identified and the display strategy is updated until there are no unprocessed categories in the category information.

[0100] In this embodiment of the present invention, by precisely locating the picking requirements for each category of workpiece, hesitation and search time during the picking process are reduced, accelerating picking speed. Clear guidance of category information reduces the likelihood of workers confusing workpieces of different categories, thereby reducing the probability of picking errors. This ensures that each category of workpiece receives appropriate attention at the appropriate time, avoiding waste of resources and excessive concentration on a single category, and improving the efficiency of the entire picking system.

[0101] In summary, by formulating and implementing a second display strategy based on category information, the picking system can manage the picking process more intelligently, which not only improves the accuracy and efficiency of picking operations, but also demonstrates the system's strong flexibility and adaptability in handling multi-category tasks.

[0102] As an optional implementation method, in response to the existence of a third category other than the first category and the second category in the category information, the third category is determined as the second category, and the second category is determined as the first category, and the following steps are performed until the third category does not exist in the category information: in response to completing the picking operation on the work object of the first category, the second category other than the first category in the category information is determined, and the second display strategy is determined to display at least light prompt information and picking quantity information on the electronic tag corresponding to the work object of the second category.

[0103] This embodiment further expands the logic for developing a secondary display strategy based on category information, introducing dynamic updates to accommodate continuous picking operations for multiple types of work objects. The key is the ability to flexibly redefine the primary and secondary categories, ensuring a consistent and efficient picking process.

[0104] Optionally, the first category of work objects to be processed, as well as subsequent second category work objects, are identified based on the category information. The electronic tags corresponding to the first category work objects display at least a light prompt and a picking quantity to guide the operator in picking. Once the first category of work objects has been picked, the category information can be immediately checked to see if a third category exists, preparing to update the category information. If a third category exists, the current second category is upgraded to the new first category, and the third category becomes the new second category. This update ensures that the operator always focuses on the next category to be processed.

[0105] Optionally, the second display strategy is updated to display corresponding light prompt information and picking quantity information for the electronic tags corresponding to the new first-category work objects, preparing to guide the operator into the next stage of picking operations. The above process will be repeated until the third category no longer exists in the category information, that is, the category currently being processed is the last category. The termination condition of the process is that the third category no longer exists in the category information. This means that all categories of work objects have completed the picking operation, or the current picking task has come to an end, and the category being processed is the last category. At this point, the system no longer needs to update the category information and re-formulate the display strategy, but instead focuses on ensuring that the current category's picking operation can be completed smoothly and accurately.

[0106] In this embodiment of the present invention, by introducing a dynamic category information update mechanism, the picking system can more flexibly respond to the picking needs of multiple types of work objects, ensuring that each type of work object is processed at the appropriate time, avoiding unnecessary waiting and stagnation, and accelerating the picking process. The clear classification and timely update of category information reduces the possibility of workers confusing different types of work objects, reducing the picking error rate. It can also rationally allocate picking resources, ensuring that each type of work object is picked within the optimized time, and improving resource utilization efficiency.

[0107] In summary, by dynamically updating category information and adjusting the display strategy in a timely manner, an efficient and accurate solution is provided for handling complex and multi-category picking tasks, reflecting the level of intelligence and automation applied by the picking system in the logistics field, and further improving the efficiency and accuracy of supply chain management.

[0108] As an optional embodiment, after performing a picking operation on a work object that meets the picking quantity information at the work position, the method further includes: triggering a picking completion instruction on the electronic tag in response to the number of work objects performing the picking operation meeting the picking quantity information; in response to the picking completion instruction, canceling the light prompt information displayed on the electronic tag and clearing the picking quantity information.

[0109] In this embodiment, during the picking operation at the workstation, not only the picking status of individual workpieces is considered, but also the overall fulfillment of the picking quantity is considered, thereby intelligently controlling the display content of the electronic tag. By introducing a comparison between the picking quantity information and the number of workpieces, this embodiment achieves the automated triggering and response of the picking completion instruction, thus improving the intelligence level of the picking process.

[0110] Optionally, the system continuously monitors whether the number of workpieces at the workstation matches the preset picking quantity information. The picking quantity information here refers to the total number of picking tasks expected to be completed at the current workstation, which can be the number of individual parts or a combination of multiple parts. Once it detects that the number of workpieces has met the preset picking quantity information, the picking task for the current workstation is complete, and the system automatically triggers a picking completion instruction on the electronic tag. This instruction is usually accompanied by a confirmation action from the workpiece, such as the operator clicking a confirmation button on the electronic tag, indicating that the picking task has been completed.

[0111] Optionally, upon receiving a pick completion indication, the electronic tag immediately clears the currently displayed light and quantity information, preparing for the next pick task. Clearing the displayed information on the electronic tag is a crucial step in the picking process, preventing information from the previous pick task from interfering with subsequent tasks and ensuring accurate information for each picking operation.

[0112] Optionally, after clearing the information, the electronic tag remains blank or displays a standby status, preventing operators from being misled by previous task information when performing a new picking task and reducing the possibility of picking errors. Once the light prompt information and picking quantity information on the electronic tag are cleared, the display content can be immediately updated to provide accurate guidance for the next picking task and accelerate the picking process. The immediate clearing of light prompt information and picking quantity information helps to quickly release and reallocate system resources, ensuring that the electronic tag at each workstation can effectively support the picking operation and improve overall picking efficiency.

[0113] In this embodiment of the present invention, by introducing an automatic triggering and response mechanism for picking completion instructions, the picking system achieves intelligent control of the picking process. Based on a real-time comparison of the number of items picked and the number of workpieces, the system automatically determines when a picking task is complete, thereby intelligently managing the display and updating of electronic tags. This mechanism not only reduces the need for manual intervention but also ensures the consistency and efficiency of the picking process.

[0114] As an optional embodiment, after clearing the light prompt information and picking quantity information displayed on the electronic tag, the method also includes: controlling the electronic tag, and sending the clearing result of the light prompt information and picking quantity information to the upstream system by the base station and the tag system.

[0115] In this embodiment, after the information on the electronic tag is cleared, a result feedback mechanism is further introduced to ensure good information synchronization between the various components of the picking system, thereby improving the overall efficiency and reliability of the picking operation.

[0116] Optionally, once the electronic tag completes information clearing, it sends a clear confirmation signal to the base station. This signal provides direct feedback upon completion of the clearing operation, indicating that the electronic tag's information display status has been reset. Upon receiving the clear confirmation signal from the electronic tag, the base station forwards it to the tag system. This forwarding step ensures that the tag system is immediately aware of changes in the electronic tag's information status, facilitating subsequent scheduling and control. The tag system collects clear confirmation signals from each electronic tag and integrates them into a comprehensive clearing results report. This provides the tag system with not only the status of individual electronic tags but also a comprehensive overview of the clearing progress of all tags throughout the picking process.

[0117] The tagging system sends the consolidated removal results to an upstream system, which may be the central dispatch system for picking tasks or a related data management system. This reporting process ensures that the upstream system has real-time access to the latest status of the picking operation, including the status of electronic tags that have been picked and cleared, providing accurate data for global picking scheduling.

[0118] As an optional embodiment, the electronic tag is used to perform wireless communication with the base station, the base station is used to perform wired communication with the tag system, and the tag system is used to perform wired communication with the upstream system.

[0119] In this embodiment, the core network architecture of the electronic tag system involves three key components: electronic tags, base stations, and tag systems (connected to upstream systems). The connection between these components determines the efficiency and security of information flow.

[0120] Optionally, wireless communication is used between the electronic tag and the base station, for example, using a 2.4GHz private protocol or Bluetooth technology. The choice of wireless communication provides flexibility and mobility, allowing the electronic tag to receive and send information without being restricted by physical connections. Wireless communication allows electronic tags to be deployed in multiple locations without the need for complex wiring, making it easy to install and maintain. At the same time, it supports long-distance data transmission and is suitable for larger picking areas or dynamic operating environments. The stability of wireless communication may be affected by environmental factors (such as obstacles and electromagnetic interference), and it is necessary to optimize the antenna design and communication protocol to ensure the accuracy and timeliness of information transmission.

[0121] Optionally, a wired connection, typically via a network cable, is used between the base station and the tag system. This connection offers higher bandwidth, lower latency, and more stable communication quality than wireless communication. Network cable connections ensure rapid information transmission from the tag system to the base station, as well as efficient command issuance and data retrieval from the base station to the electronic tags. This reduces potential transmission delays in wireless communication and is crucial for real-time picking operations. Wired connections limit the mobility of the base station, and deployment requires consideration of the availability and topology of the network infrastructure to ensure a stable physical connection between the base station and the tag system.

[0122] Optionally, the labeling system can also connect to upstream systems via a network cable. This direct and fast connection facilitates immediate data synchronization and updates. This network connection ensures that key instructions from the upstream system, such as picking tasks and inventory information, are quickly and accurately transmitted to the labeling system, effectively controlling the operating status of the electronic tags. This ensures a stable network connection between the labeling system and upstream systems, capable of handling the large amounts of data exchanged during peak periods, and avoids information congestion and transmission errors.

[0123] In this embodiment of the present invention, the entire picking system architecture, through a combination of different connection methods, enables rapid and accurate information transmission from upstream systems to electronic tags, laying the foundation for efficient picking operations. The combination of wireless communication and wired connections not only meets the needs of mobility and flexibility, but also ensures the stability and security of core data exchange. The deployment of wireless electronic tags reduces dependence on physical space and wiring costs, while wired connections provide reliable data transmission channels between core nodes, achieving a balance between cost and performance.

[0124] In an embodiment of the present invention, corresponding electronic tags can be pre-deployed for different work object workstations. If a work object needs to be picked, the number of target objects to be picked can be obtained, and the electronic tag can be assigned a corresponding number of light prompt types based on the number information. Specifically, each type of light prompt corresponds to one target object. If a picking task for a work object is detected, the electronic tag can be controlled to secretly display the corresponding light prompt information and picking quantity information. The target object corresponding to the light prompt type can be controlled to perform a picking operation on the work object at the corresponding workstation, with the number of work objects to be picked meeting the picking quantity information. In this embodiment, the dynamic prompt and feedback mechanism of the electronic tag, combined with accurate picking quantity information, effectively improves the accuracy and speed of work object picking. This overcomes the limitations of related technologies such as slow information updates, resource waste, and high operator proficiency requirements, significantly improving picking efficiency and reducing potential picking errors and rework costs. This achieves the technical effect of improving work object picking efficiency and solves the technical problem of low work object picking efficiency.

[0125] The technical solutions of the embodiments of the present invention are described below with reference to preferred implementation methods.

[0126] The embodiments of the present invention mainly address the following two pain points: Currently, automobile logistics parts information is displayed on paper labels, requiring technicians to constantly update part information, print and affix labels, which results in high labor load, difficulty in information storage and traceability, and paper waste; Currently, parts picking and stocking require operators to print stocking lists and stock according to the stocking lists, which consumes a large amount of paper, ink and other consumables, and requires high proficiency of operators. They need to quickly find the corresponding parts according to the stocking lists, which has high personnel training costs and is prone to stocking errors, resulting in the risk of rework or even production line shutdowns.

[0127] To address these pain points, the present invention provides a method for using electronic tag technology to guide stocking and picking operations in the automotive logistics sector. This method, which transforms electronic tags used in the retail industry for information display and maintenance, provides low-cost guidance and error prevention for parts picking and stocking operations. Paper label maintenance is replaced with electronic label maintenance, and on-site label affixing is replaced with remote system modification, significantly reducing labor hours. Paper labels and paper stocking sheets are eliminated, eliminating paper waste. Multi-color indicator lights guide workers through stocking and picking operations, reducing both operator proficiency requirements and the risk of stocking errors.

[0128] The following is a further introduction to the embodiments of the present invention.

[0129] Figure 2 This is a schematic diagram of a system for preparing and picking goods using electronic tag technology in the automotive logistics field, according to an embodiment of the present invention. The system may include an upstream system 201, a tag system 202, a base station 203, a base station 204, an electronic tag 205, and an electronic tag 206. The electronic tag is connected to the corresponding base station via a 2.4GHz proprietary protocol (or Bluetooth). The base station is connected to the tag system, the upstream system, and the server host via a network cable. The base station can transmit commands from the server host to the electronic tag and transmit data returned by the electronic tag back to the server host. The server host and the management system are responsible for storing, managing, and controlling the data information. Because the upstream system, tag system, and base station are linked via a network cable, the transmission speed is extremely fast, in the millisecond range. However, the base station and electronic tag are linked via a long-range 2.4GHz proprietary protocol (or Bluetooth), resulting in slower information transmission speeds, typically in the single digits of seconds. This information primarily impacts the time requirements for picking and preparing goods.

[0130] The electronic display of parts information is the basic function of electronic labels. The label screen can customize the display content and can be modified through the label system. When the part information changes, the corresponding part information is manually adjusted on the label system platform. The system sends the command to each electronic label through the base station to complete the change of the electronic label display information.

[0131] Electronic tags are used to guide the picking and stocking of parts to achieve error prevention. Assume the following situation: the picking and stocking area has two types of vehicles, and the parts of each vehicle are distributed in four directions: left front, left rear, right front, and right rear. There are 4 picking and stocking operators and 4 frame carts. Each frame cart requires 5 minutes of picking time, and each frame cart has 20 parts.

[0132] FIG3 (a) is a schematic diagram of a picking and stocking process according to an embodiment of the present invention. As shown in FIG3 (a), it can include 4 workers (A, B, C, and D), and each of them corresponds to a frame cart. The four workers start working at the same time to pick and stock. The label system is connected to the upstream picking and stocking management system. The upstream system sends the picking task (in frame carts). After receiving the task, the label system sends it to the base station. The base station sends the instruction to the terminal label. The parts in the four areas of left front → left rear → right front → right rear are lit in sequence. All the parts to be picked in the left front area are lit, and the number of pickings is displayed on the screen. After the operator completes the picking of each part, he presses the button on the label and sends back the completion information. The part label turns off. After all the parts in the left front area are picked and stocked, all the parts to be picked in the left rear area are lit. The above operation is repeated. The four areas are lit in sequence, and finally the picking and stocking of parts for a frame cart is completed. The number of light colors must be the same as the number of operators at the same time. Different colors are used to distinguish the tasks of different operators. It takes time to transmit the information of lights on and off (please refer to the information transmission process in Section 1 for the length of time). This solution has low requirements for information transmission time. A total of 4 range lights are turned on, and the single range light-up time is about 10-15s, which has less impact than the time required to manually check the screen and pick up parts.

[0133] Figure 3(b) is a schematic diagram of another picking and stocking process according to an embodiment of the present invention. As shown in Figure 3(b), if there are two types of vehicles for the stocking picking operations to be performed continuously, staff members can be assigned to the two types of vehicles for picking at the same time. For example, A is assigned to vehicle type one, and B is assigned to vehicle type two. If A finishes picking the parts on the left front of vehicle type one, C can be assigned to vehicle type one, and so on.

[0134] However, the above scheme requires a long waiting time for personnel, and the previous personnel must complete picking and preparing goods before starting, and the operation is highly intermittent.

[0135] Optionally, the form of lighting up the parts in the four fixed areas of left front → left rear → right front → right rear in sequence is changed to lighting up the first part in the first person's task list, and displaying the picking quantity on the screen. After the first person completes picking the part, he presses the button on the label and sends back the completion information. The part label goes out and the second part lights up. The principle of lighting up the parts in the same area in a concentrated manner (after the parts in the left front area are picked, the parts in the left rear area are lit up). A total of 20 lights are lit to complete the picking of the task list. After the first person completes or passes the first part in the second person's task list, the second person starts lighting up, and then repeats the rules of lighting up 20 times to complete the corresponding task list. Subsequent personnel repeat the above actions; the number of light colors must be the same as the number of workers at the same time, and different colors are used to distinguish the tasks of different workers.

[0136] The transmission of information about lights on and lights off takes time (please refer to the information transmission process in Section 1 for the length of time). This solution places extremely high demands on the information transmission time. For a 5-minute picking time and 20 types of parts, the picking and stocking time for a single part is 15 seconds. Excluding the time for personnel to view the screen and walk to pick up parts, it is recommended that the time interval between lights on and lights off be less than 5 seconds to ensure the continuity of the picking action and adapt to the picking time requirements. The specific time interval between lights on and lights off needs to be calculated based on actual conditions. Due to wireless transmission between base station tags, the time interval cannot be compressed to a shorter time, which has a great impact on actual operations. This method requires shorter waiting time for personnel, but places extremely high demands on the time for transmitting information about the lights on and lights off of tags. If the information transmission time is too long, there will be a risk of downtime.

[0137] According to an embodiment of the present invention, a device for picking work objects is further provided. It should be noted that the device for picking work objects can be used to execute the method for picking work objects in the above embodiment.

[0138] Figure 4 is a schematic diagram of a device for picking work objects according to an embodiment of the present invention. Figure 4 As shown, the picking device 400 for the work object may include: an acquisition unit 402 , a first control unit 404 and a second control unit 406 .

[0139] The acquiring unit 402 is configured to acquire quantity information of target objects to be picked, and set light prompt information of the electronic tag based on the quantity information.

[0140] The first control unit 404 is configured to control the electronic tag to display at least light prompt information and picking quantity information in response to detecting a picking task of the work object.

[0141] The second control unit 406 is used to control the target object corresponding to the type of the light prompt information to perform a picking operation on the working object that meets the picking quantity information at the working position.

[0142] In an embodiment of the present invention, the acquisition unit 402 acquires the quantity information of the target objects for the work objects to be picked, and sets the light prompt information of the electronic tag based on the quantity information; the first control unit 404 controls the electronic tag to display at least the light prompt information and the picking quantity information in response to the detection of the picking task of the work object; the second control unit 406 controls the target object corresponding to the type of the light prompt information, and performs a picking operation on the work object that meets the picking quantity information at the work position, thereby solving the technical problem of low picking efficiency of the work object and achieving the technical effect of improving the picking efficiency of the work object.

[0143] According to an embodiment of the present invention, a computer-readable storage medium is further provided. The storage medium includes a stored program, wherein the program executes the method for picking work objects in the above embodiment.

[0144] According to an embodiment of the present invention, a processor is further provided, which is used to run a program, wherein the method for picking the work object in the above embodiment is executed when the program is run.
