Technical Field

[0001] The present invention relates to the technical field of warehousing logistics, and in particular to an AGV sorting workbench lighting system and application thereof. Background Art

[0002] With the rapid development of e-commerce, logistics and warehousing industries, automation technology has been widely used in the field of warehousing and logistics. As a key component of automated warehousing systems, automated guided vehicle (AGV) technology can realize the automatic transportation, sorting and storage of goods, improve warehousing efficiency and reduce manpower requirements. However, the existing AGV sorting system still has some technical limitations in the collaborative operation with the sorting workbench, especially in terms of operation prompts and error rate control.

[0003] At present, AGV systems are usually used in combination with sorting workbenches to automatically sort goods in warehouses or logistics centers. However, in actual applications, due to the lack of intuitive operating instructions, sorters often need to manually identify the location and sorting order of cargo pallets. This operation method is not only prone to low sorting efficiency, but also prone to sorting errors. In addition, the feedback mechanism of the existing sorting system is lagging, and it is impossible to timely feedback the completion status of the sorting task, which further increases the complexity of the operation and the possibility of errors.

[0012] As a preferred solution of the AGV sorting workbench lighting system of the present invention, the lighting system includes green light, red light and yellow light, wherein the green light is used to indicate the target pallet, and the yellow light is used to indicate abnormal status and equipment failure.

[0013] As a preferred solution of the AGV sorting workbench lighting system of the present invention, the electronic tag system adopts a dual backup magnetic terminal design to ensure the stability of communication and support hot plug operations in a powered state.

[0014] As a preferred solution of the AGV sorting workbench lighting system of the present invention, the indicator light of the lighting system can indicate the urgency of the task through changes in color, flashing frequency and brightness according to different sorting tasks.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Reference Figure 1-3 The present invention provides an AGV sorting workbench lighting system, comprising:

[0037] Warehouse Execution System (WES): used to generate and issue picking tasks, which include identification information of the target pallet and the original pallet;

[0038] Warehouse Control System (WCS): used to detect the tasks issued by the warehouse execution system in real time and send instructions to the lighting devices;

[0039] Lighting system: installed on the sorting workbench, it indicates the position and operation status of the target pallet and the original pallet through lights of different colors;

[0040] Electronic label system: Using carrier communication technology, power and data are transmitted simultaneously through two wires. The electronic label system is connected to the warehouse control system to transmit the sorting status in real time and feedback the task completion status. This design greatly reduces the equipment installation and maintenance costs and avoids system failures caused by installation errors or complex wiring.

[0041] Among them, the warehouse control system detects the tasks issued by the warehouse execution system at intervals of every 2 seconds. When a new unprocessed task is found, it sends a lighting instruction to the lighting system and updates the indicator light status according to the task completion status. The real-time monitoring mechanism significantly improves the response speed of the system, making sorting operations more flexible, reducing task delays and backlogs, and at the same time can dynamically optimize the task execution order to ensure the efficient operation of the system.

[0042] Furthermore, the lighting system includes a green light, a red light and a yellow light, wherein the green light is used to indicate a target pallet, and the yellow light is used to indicate an abnormal state and equipment failure, and the target pallet is clearly distinguished from the original pallet through the lighting system.

[0043] Furthermore, the electronic tag system adopts a dual backup magnetic terminal design to ensure the stability of communication and support hot-swap operation under power. The dual backup magnetic terminal design enhances the stability and reliability of communication and ensures that the system can still work normally under high-frequency operation. By supporting hot-swap operation under power, the equipment can be maintained and replaced without affecting the operation of the system, reducing downtime.

[0044] Furthermore, the indicator lights of the lighting system can indicate the urgency of the task through changes in color, flashing frequency and brightness according to different sorting tasks. Different light colors, frequencies or brightness prompts can avoid operational errors caused by recognition errors in traditional sorting systems. This method not only effectively improves the sorting accuracy, but also makes the sorting tasks more intuitive. Sorters can make accurate judgments quickly through light prompts, reducing the complexity of sorting operations.

[0045] Furthermore, the system supports parallel operation of multiple pallets, and indicates the task status of multiple pallets through indicator lights of different colors.

[0046] Furthermore, the system adopts modular design, and the lighting system, warehouse control system and electronic tag system can be replaced and expanded independently to meet the storage needs of different scales. The modular design makes the system highly scalable and compatible.

[0047] Furthermore, the warehouse control system can dynamically adjust the lighting indication according to the task priority to optimize the processing order of the sorting tasks.

[0048] Furthermore, the system has a self-diagnosis function that can detect the working status of the lighting system and electronic tags, and automatically generate maintenance tasks when a fault occurs.
