First Claim
Patent Images
1. A RFID reader system comprising:
- a reader body;
a reader module disposed in the reader body;
an antenna unit detachably installed onto the reader body;
an antenna detection switch connected with the reader module and disposed in the reader body;
a protection circuit disposed in the reader body; and
a control module connected with the reader module and disposed in the reader body;
wherein;
when the antenna unit is installed onto the reader body, the reader module is configured to interrogate and detect an external RFID tag through the antenna unit;
the antenna detection switch is configured to detect whether the antenna unit is installed onto the reader body, to connect the antenna unit when finding the antenna unit is properly installed onto the reader body, and to connect the protection circuit when finding the antenna unit is not properly installed onto the reader body; and
the control module is configured to control the reader module to interrogate an external RFID tag in a read cycle and transmit information about the RFID tag back to the control module.
