About the method of container gantry crane to identify the plate number and vehicle number of trucks

Abstract

The invention discloses a method for container gantry cranes to identify the license plates and car numbers of trucks, comprising the following steps: step 1, installing a UWB base station, and installing an image acquisition device on the gantry crane; step 2, writing the car number into the UWB In the label; step 3, install the UWB device on the vehicle board of the truck; step 4, if the truck moves to the area identified by the UWB base station, the UWB device and the UWB base station communicate with each other, and at the same time the UWB base station After receiving the information of the UWB device, the vehicle plate number of the collection truck can be obtained, and then the positioning data of the spreader of the container gantry crane can be obtained by positioning, so as to determine the position data of the collection truck at this moment; step five, capture the picture of the collection truck; step 6. Identify the plate number of the front of the truck. The invention automatically completes the automatic information collection of the plate number of the collection truck and the plate number of the front of the truck, automatically completes the global positioning of the collection truck, has high collection work efficiency and high accuracy, and greatly improves collection efficiency.

Description

technical field [0001] The invention relates to a method for identifying the plate number and vehicle number of a collection truck with respect to a container gantry crane. Background technique [0002] In the loading and unloading of containers in the railway yard, the front of the truck and the plate of the truck can be combined arbitrarily. There is a plate on the head of the truck, and the plate of the truck also has a plate. The operation is related to whether the container corresponding to the plate number of the truck is loaded correctly, and whether the user is connected with the railway freight system correctly. Since the front of the truck and the board of the truck can be combined arbitrarily, there is no relatively direct way to collect the license plate and vehicle number of the truck. At present, the information system can only use the method of manually confirming the license plate and vehicle number of the truck or real-time identification of the current vehi...

Problems solved by technology

Since the front of the truck and the board of the truck can be combined arbitrarily, there is no relatively direct way to collect the license plate and vehicle number of the truck. At present, the information system can only use the method of manually confirming the license plate and vehicle number of the truck or real-time identification of the current vehicle through video. The vehicle number and plate number of the trucks inside the truck channel, the overall work efficiency is not high, error-prone, and cannot accurately correspond to the vehicle number and plate number of the trucks currently working. The front of the truck and the plate of the collecting truck can be combined arbitrarily, so that when the rail crane is working on the collecting truck, the plate number of the collecting truck cannot completely correspond to the plate number, and manual collection is very cumbersome and time-consuming.
