Three-dimensional surrounding tracing type radio frequency identification system and goods detection method thereof

The invention relates to the field of radio frequency identification and discloses a three-dimensional surrounding tracing type radio frequency identification system and a goods detection method of the three-dimensional surrounding tracing type radio frequency identification system. The three-dimensional surrounding tracing type radio frequency identification system comprises a goods channel, a sensor, antenna rotary devices and an antenna gate. The goods channel penetrates through the antenna gate. The sensor is in communication connection with the antenna rotary devices and used for detecting the goods channel and sending a detection result to the antenna rotary devices. The antenna gate comprises N antennas corresponding to the antenna rotary devices one to one. The antenna rotary devices are used for judging whether goods exist on the goods channel or not according to the detection result of the sensor and rotating the antennas when the goods exist on the goods channel, wherein N is a natural number large
