1. Application background
In recent years, my country’s electrolytic aluminum technology has made considerable progress, especially the widespread application of large-scale pre-baked cells. Related technologies have been world-leading. With the advancement of technology and technology, supporting control systems have also emerged. The UHF reader/writer plays a vital role in the whole system. It uses radio frequency identification technology to collect the corresponding slot number and package number, and forms data interconnection through wireless networking technology, which forms a key to the automatic aluminum discharging process. Automatic control.
In the entire automation process, the ability to accurately identify the corresponding slot number and package number electronic label data becomes the key. In the field, under high-intensity magnetic field interference environment, high requirements are placed on the stability and environmental adaptability of the reader .
Two, case show
Take one of the cases as an example:
1. Installation method of slot number reader
2. Slot card installation position
3. Installation method of package number reader
4. Installation method of package number card
5. Aluminum tapping process
Lift the package number first, no need to identify it at this time.
Drive the vehicle to the trough where aluminum is to be drawn, and the trough number that is read during the driving process will not be counted.
Adjust the orientation of the bag
After the bag is placed, the aluminum is tapped. This time the aluminum is tapped in slot 3047. The aluminum is currently being tapped. During this process, ensure that the corresponding slot number and packet number are read, and the system will automatically make statistics and records.
Weight statistics during the aluminum tapping process
Finally, the vehicle is loaded and the aluminum tapping is completed.
6. Before leaving the factory after loading the vehicle, it must be weighed again by the platform scale. At this time, the UHF reader can also be used to realize unattended weighing.

Three, application summary
In the entire aluminum tapping process, the UHF reader needs to ensure that the corresponding slot number card data is accurately recognized, and the package number card data must be recognized to complete the entire operation. Therefore, the performance of the reader and the choice of electronic tags are very important. The key is to ensure that the reader can recognize stably under high temperature, high magnetic field, and all-metal environment at the same time. It is very difficult for customers to achieve this function perfectly after using the reader produced by our Jietong Technology. The smooth operation of the system.
