RFID working principle and workflow
1. Principle of operation
The reader emits energy in an area to form an electromagnetic field. The radio signal is detected through the area, and then the memory signal is sent. In order to realize identification, the working mode of RFID is divided into electromagnetic mode and microwave mode.
Second, the work process
1. The reader transmits radio communication signals through an antenna.
2. When the radio frequency tag is launched into the working area of the antenna, the radio frequency tag will transmit information through the antenna after it is activated.
3. The receiving antenna of the system receives the received signal and transmits it to the reader through the antenna adjuster. The radio frequency reader demodulates and decodes the received signal and sends it to the background of the computer controller.
4. The computer controller judges the legitimacy of the label according to the logic logic, processes and controls different settings accordingly, and sends out instruction signals to control the action of the actuator.
5. The actuator operates according to computer instructions.
6. Through the computer communication network, the various monitoring points are connected to form a general control information platform, and then different software can be designed to achieve different functions according to different projects.
