Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle identification, and particularly relates to an AGV vehicle bayonet identification system. Background Art

[0002] An Automated Guided Vehicle (AGV), also known as an automated guided cart or an automatic guided cart, is an industrial vehicle that loads goods automatically or manually, travels automatically along a set route or tow a load-carrying trolley to a designated location, and then loads and unloads goods automatically or manually. According to the definition of JISD6801 in Japan: an AGV is an industrial vehicle that is automatically operated with a battery as the power source. Only when an automated guided vehicle forms an automated guided vehicle system (AGVS) with an automated guidance system, an automatic loading and unloading system, a communication system, a safety system, a management system, etc. according to the requirements of material handling operation automation, flexibility, and punctuality can it truly play its role. The continuous development of computer hardware technology, parallel and distributed processing technology, automatic control technology, sensor technology, and software development environment provides the necessary technical basis for the research and application of AGVs. The development of artificial intelligence technologies such as understanding and search, task and path planning, fuzzy and neural network control technologies has enabled AGVs to develop towards the direction of intelligence and autonomy. The research and development of AGVs integrate artificial intelligence, information processing, and image processing, involving multiple disciplines such as computers, automatic control, information communication, mechanical design, and electronic technology, and have become one of the hotspots in the research of logistics automation. With the development of Internet technology, it has become possible to achieve efficient production management in the informatization of all walks of life. For manufacturing enterprises, a large amount of bulk materials in the enterprise need to be transported by AGV vehicles, and the logistics management of the entry and exit of AGV vehicles is of great significance to the enterprise.

[0003] In order to identify the information of AGV vehicles entering and leaving the warehouse, a barrier gate is usually installed on the freight passage, and when an AGV vehicle passes through the barrier gate, the driver needs to drive the vehicle manually. In the prior art, the logistics management of AGV vehicles and the bayonet management of vehicle weighing and measurement data still stay in the manual management stage, or are managed by RFID or IC card swiping methods. However, the manual management method has problems such as long weighing time and low efficiency, resulting in long queues of vehicles waiting; the management method by RFID or IC card swiping has a link of queuing for card issuing, which requires additional management personnel and hardware devices such as a PC, a card issuer, and a printer. While the hardware cost increases, the efficiency has not been effectively improved. Summary of the Utility Model
