General introduction of RFID system
System principle
The APS real-time positioning and tracking system uses RFID (electronic tag) as the most advanced identification code at present. It has the characteristics of not easy to break, reliable data, long service cycle, and long effective communication distance. It is an alternative to barcode and infrared identification. The best choice. Install it on the controlled target as the unique identifier of the target for tracking and positioning.
At work, managers use networked wireless identification base stations to track and locate targets.
Electronic label
Simply put, electronic tag (RFID) technology is a non-contact automatic identification technology. Its basic principle is to use radio frequency signals and their spatial coupling and transmission characteristics to realize automatic machine identification of stationary or moving items to be identified.
The radio frequency identification system generally consists of two parts, namely the electronic tag and the reader. In the application, the electronic tag is attached to the object, equipment, and person to be identified. The reader is used to automatically remove the electronic tag in a non-contact manner when the object, equipment, or person to be identified It is agreed that identification information is taken out or specific information is written, so as to realize the function of automatically identifying items or automatically collecting item identification information.
Since RFID does not require a light path between the tag and the reader, the shortcomings of other automatic identification systems (such as bar codes) are avoided. This ensures that the RFID system can be used in harsh environments, such as dust, dirt, high humidity, and poor visibility environments. The biggest advantage of RFID is that it can still get a satisfactory read and write speed under the above-mentioned harsh environment. In most cases, it can respond within 100 milliseconds. In addition, the reading and writing of RFID is completely automatic and transparent, and there is no need to manually scan the tracked object, nor does it need to activate the magnetic stripe reader, IC card reader, etc. like other contact tag technologies.
