Description

   Container yard loading and unloading container tracking system and method   

The invention belongs to a container yard loading and unloading container tracking system and method, and particularly relates to tracking a container number through two-dimensional bar code and RFID (Radio Frequency Identification) technology, and supplemented by image identification and comparison of the container number in the RFID. The container number can be used for container loading and unloading operations in the aviation container yard. When the container is transported from the storage area to the container wheel loading operation, and when the container is unloaded from the container to the storage area, the crane cabinet number and the trailer are confirmed and transported. Checking the correctness of the trailer-carrying containers on the way, there is no need to build a large number of container identification systems at the crane end to replace the current manual inspection mistakes, and to ensure the accuracy of the crane loading and unloading of the containers, and improve the efficiency of the container yard operation.

At present, the operation of commercial container yards is based on the terminal operation system (TOS) as the management core. Containers are transported in the container yards by trucks. Take storage containers for loading and leaving the port as an example. Storage area cranes (doors) The crane lifts the container and loads it on a trailer, which is carried by the trailer to the side of the container ship, and then lifted by the shipside crane (bridge crane) to load the container on the container ship. The crane operator can obtain the location of the container to be hoisted, the container number, and the number of the trailer to be loaded from the container yard operation system, lift the marked container through the crane, and look at the trailer number on the top of the trailer from a height to load the container. However, In addition to visual inspection, crane operators do not have identification tools to confirm whether the container being hoisted is correct. They must trust the storage area records of the container yard operating system or manual inspection by ground personnel. The crane operation at the loading side also has the same problem. The shipside tallyman needs to manually check the order of container loading in order, and then the bridge crane operator loads the container in order to ship the shipside tallyman and shipside crane. As far as the operator is concerned, there is no identification tool for automatic inspection. Similarly, the container can be unloaded by the shipside crane, loaded on a trailer, and transported to the storage area. The crane can not be automatically inspected when it is hoisted into the storage area.

Recent technologies include shipside / storage area container identification systems, such as the container verification module in the Republic of China Patent I505206. Several identification cameras are installed on the shipside / storage area cranes to automatically identify the container number and send it to the container yard operation system for comparison. Make sure that the cabinet is correct. However, the shipside / storage area crane usually spans 4 to 5 lanes. There are problems with trailers blocking image acquisition and camera focusing. There are also problems with different container number acquisition positions. You need to install a lot of cameras to increase identification. Coverage area, in order to respond to the parking position of various container vehicles, the container identification system at the side / storage area can hardly be widely used in commercial container yards. In addition, in the patent of the Republic of China I505206, RFID is used as a guide vehicle, but the RFID misreading prevention mechanism is not designed. Because the container information is not written, it cannot be checked offline.

In view of the various shortcomings derived from the above-mentioned conventional methods, the inventor of this case has been eager to improve and innovate. After years of painstaking and meticulous research, he finally successfully developed and completed the container yard loading and unloading container tracking system and method.

In order to achieve the above object, the purpose of the present invention is to provide a container yard loading and unloading container tracking system and method, which can write a container number into a bar code and a label module during trailer loading, and compare the modules via a container during shipping. Use image recognition technology to check whether the container number and bar code are consistent with the label module and make notes. Finally, the unloading end compares the bar code with the container number posted in the label module to improve the lack of manual inspection and avoid it. Difficulties in the construction of container identification systems alongside ships or storage areas. In order to respond to the busy container yard operation, when reading and writing the container number, the RFID tags of adjacent vehicles may be misread and cause errors. The present invention designs a tag identification module, which uses a two-dimensional barcode identification unit and an RFID reading and writing unit to match each other. When the RFID read-write unit reads and writes the container number, it is necessary to confirm whether the TID (Tag Identifier) of the read-write RFID tag is consistent with the hidden RFID TID code obtained from the two-dimensional barcode information to avoid the above-mentioned deficiency.

A container yard loading and unloading container tracking system and method that achieves the above-mentioned object of the invention is that when a crane loads a container to a trailer, the container number is written into a bar code and a label module to facilitate subsequent tracking of the container transportation.
