The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] The following will explain in detail how to improve the efficiency and accuracy of vehicle inventory with reference to specific embodiments and drawings.

[0020] Embodiment 1 See also Figure 1 , shown is a vehicle inventory counting method based on RFID tags in the first embodiment of the present invention, which is used to count vehicles in a warehouse, wherein the vehicles are provided with RFID tags, an electric slide rail is laid on the ceiling of the warehouse, the electric slide rail covers the vehicle parking area in the warehouse, an RFID tag collector that can slide along the electric slide rail is installed on the electric slide rail, and the method includes steps S10~S12.

[0021] Step S10, when a vehicle inventory count instruction is received, the RFID tag collector is controlled to move along a preset path.

[0022] Among them, RFID electronic tags are installed for each car, giving them unique identity IDs, and the association record of vehicle information and ID can also be established in the database. This ensures that the information of each car is accurate and facilitates subsequent management and tracking. An electric slide rail system is installed on the ceiling of the warehouse, and RFID tag collectors are installed on the slide rails. These collectors can move along the slide rails and automatically read the RFID tag information on the cars below. By receiving inventory instructions, the RFID tag collector is controlled to start moving and collecting. Specifically, a timed trigger or manual trigger mechanism can be set to enable the RFID tag collector to automatically move along the slide rail.

[0023] More specifically, the preset path can be a default path for a full scan of the vehicles in the warehouse, or it can be a path set in advance according to the distribution of vehicles in the warehouse. The path for a full scan can fully understand the situation in the entire warehouse, such as whether there are vacancies, and the path set according to the distribution of vehicles in the warehouse can efficiently and directly obtain the vehicle information of each vehicle. When performing a full scan, the preset path is a fixed path, and when determining the set path, the coordinate information of each vehicle in the warehouse can be obtained, and the vehicle can be mapped to the preset coordinate system according to the coordinate information; determine a target vehicle at the outermost side as the starting point of the preset path, and connect the vehicles in sequence according to the distance from the target vehicle according to the coordinate information to determine the preset path.

[0024] Step S11, while the RFID tag collector is moving along a preset path, the RFID tag collector is controlled to read the RFID tags on the vehicles in the vehicle parking area to obtain the vehicle information in the warehouse.

[0025] During the movement of the collector, the collector can be controlled to read the RFID tags on the vehicles in the parking area, so as to determine the vehicle information stored in the warehouse and the corresponding distribution of the vehicles in the warehouse.

[0026] Step S12, determining the vehicle inventory information in the warehouse according to the vehicle information, and uploading the vehicle inventory information to a preset database. Among them, the vehicle inventory information in the current warehouse is determined based on the acquired vehicle information, and this data is uploaded to the database in real time.

[0027] In addition, in some optional embodiments of the present invention, the information of the storage location of each vehicle is automatically recorded by analyzing the collected data, and the information is displayed in an intuitive way in the background management system. Managers can easily view the storage location distribution of vehicles, storage location vehicle details, etc., providing strong support for vehicle scheduling and inventory management. At the same time, a full disk read scan is performed in the warehouse to obtain the distribution of vehicles in the warehouse; the distribution of vehicles and vehicle information are obtained to form an inventory report. Inventory reports are generated regularly and automatically sent to warehouse managers. These reports record in detail key information such as vehicle inventory changes and storage location occupancy, helping managers to understand the warehouse operation status in a timely manner and provide strong support for decision-making.

[0028] In summary, the vehicle inventory counting method based on RFID tags in the above embodiments of the present invention installs RFID electronic tags for each car, gives them unique identity IDs, installs an electric slide rail system on the ceiling of the warehouse, and installs RFID tag collectors on the slide rails. These collectors can move along the slide rails and automatically read the RFID tag information on the car below, so that the RFID tag collectors can automatically move along the slide rails to collect the inventory information of the vehicles in the garage, and upload these data to the database in real time. Warehouse managers can accurately grasp the vehicle inventory without manual inventory, which improves efficiency and accuracy and solves the problems of low efficiency and low accuracy in vehicle inventory in the prior art.

[0029] Embodiment 2 The embodiment of the present invention also proposes a vehicle inventory counting method based on RFID tags. The vehicle inventory counting method based on RFID tags proposed in this embodiment is different from the vehicle inventory counting method based on RFID tags proposed in the first embodiment in that: The electric slide rails are distributed in a grid pattern, and each of the grids corresponds to a parking space for each of the vehicles.

[0030] The step of determining the preset path also includes: Mapping the grid and the vehicles to a preset coordinate system, and calculating the distance between each pair of the vehicles; Selecting a position of the vehicle as an initial starting point, and selecting the position of another vehicle that is closest and has not been visited each time, and gradually generating an initial path; Find possible path optimizations by swapping two edges in the path. After each swap, check whether the new path is shorter than the current path. If yes, a new path is adopted to optimize the initial path until the optimization is completed to obtain a final path as the preset path.

[0031] The electric slide rails are arranged in a grid, and the parking space of each vehicle is in a grid. In order to reduce the distance when collecting data for some of the vehicles, that is, to further improve efficiency, the distance between each pair of vehicles is calculated, starting from a starting point, and the nearest and unvisited punctuation points are selected each time to gradually generate the initial path. In this way, a shorter path can be quickly generated, but it is not the optimal path. By exchanging two edges in the path, possible path optimization is found. After each exchange, check whether the new path is shorter than the current path. If so, the new path is adopted. This method can significantly optimize the initial path and reduce the total distance.

[0032] In summary, the vehicle inventory counting method based on RFID tags in the above embodiments of the present invention installs RFID electronic tags for each car, gives them unique identity IDs, installs an electric slide rail system on the ceiling of the warehouse, and installs RFID tag collectors on the slide rails. These collectors can move along the slide rails and automatically read the RFID tag information on the car below, so that the RFID tag collectors can automatically move along the slide rails to collect the inventory information of the vehicles in the garage, and upload these data to the database in real time. Warehouse managers can accurately grasp the vehicle inventory without manual inventory, which improves efficiency and accuracy and solves the problems of low efficiency and low accuracy in vehicle inventory in the prior art.
