Description

Technical Field

[0001] The utility model relates to the technical field of RFID identification of a whole truck cargo, and more specifically, to an RFID identification device for a whole truck cargo. Background Art

[0002] In the warehousing and warehousing production process, it is difficult to meet the actual needs by manually checking the number of goods entering and leaving the warehouse. At present, the application of RFID (Radio Frequency Identification) technology can realize the rapid and accurate statistics of the number of goods entering and leaving the warehouse. Therefore, RFID non-contact automatic identification technology has been more and more widely used in manufacturing enterprises.

[0003] The advantage of the detection equipment for counting the number of semi-open semi-flatbed trucks entering and leaving the warehouse is that it can complete the input and processing of information without direct contact, optical visibility, and human intervention. However, the recognition antennas of the existing detection equipment for counting the number of semi-flatbed trucks entering and leaving the warehouse are all fixed. After loading, the semi-flatbed trucks will pass through the channel of the detection equipment. Since the side rails and side panels of the trucks are made of metal, electromagnetic interference will be generated. The fixed recognition antennas are difficult to recognize cargo labels that are located deep and tricky (such as corners), resulting in missed detection or wrong detection, which greatly reduces the recognition accuracy of the recognition equipment.

[0032] The gantry frames 7 are arranged at intervals along the length direction of the vehicle passage 6. In other embodiments, the user may also increase or decrease the number of the gantry frames as required, which is not limited to the present embodiment.

[0033] In this embodiment, four gantries 7 are arranged at intervals along the vehicle passage 6, and the central aisle of each gantry and the space between two adjacent gantries are arranged in sequence, namely the vehicle passage 6. Of course, in other embodiments, the vehicle passage 6 can also be formed by other forms of passages that can realize the function of passing trucks, such as forming a vehicle passage through an awning with entrances and exits at both ends and a passage inside, which is not limited to this embodiment.

[0034] In order to make the installation of the gantry more stable, a connecting beam 9 may be welded between the top cross beams of two adjacent gantries so that all the gantries are connected into a whole, thereby increasing the stability of the gantry.

The RFID identification antenna of this embodiment can be connected to an electronic device with RFID data collection, RFID judgment and other functions through a wired or wireless connection method, but this embodiment does not involve improvements in this aspect and will not be repeated here.

[0044] In this embodiment, a height limit rod 10 may be further provided at the entrance of the vehicle passage to prevent trucks exceeding the set height from passing through and damaging the equipment. A floor scale 11 may also be provided at the bottom of the vehicle passage 6 to achieve truck weighing.

[0045] The utility model can be applied to RFID cargo identification scenarios of semi-flatbed trucks and semi-open trucks. When the truck is loaded with cargo and entering or leaving the warehouse, the truck passes through the vehicle channel, and the side rotation drive device can drive the side RFID antenna to rotate to adjust the direction and position of the side antenna. The upper translation drive device can drive the RFID antenna to translate along the vehicle channel, and the upper rotation drive device can drive the upper RFID antenna to rotate to adjust the direction and position of the upper antenna, so that the RFID antenna can detect and identify from multiple directions and angles, so as to realize dead-angle detection of cargo label identification and prevent the occurrence of false detection and missed detection.
