| Zusammenfassung: | The utility model relates to the field of radio frequency identification, and discloses a three-dimensional surround tracking type radio frequency identification system. The three-dimensional surround tracking type radio frequency identification system includes a cargo channel, a sensor, an antenna rotation device, and an antenna door. The cargo channel passes through the antenna door, the sensor is in communication connection with the antenna rotation device and is used for detecting the cargo channel and transmits detection results to the antenna rotation device, the antenna door includes N antennas which are correspondingly connected with the antenna rotation device one by one, the antenna rotation device determines whether cargos are on the cargo channel or not based on detection results of the sensor and rotates the antenna if there are cargos on the cargo channel, wherein N is a natural number greater than 1. By means of the three-dimensional arrangement and the rotary antenna, the antenna signal covera |
