The invention discloses a wireless communication system which comprises a plurality of outdoor antenna units, a Zigbee wireless network, a plurality of electronic labels, a plurality of electronic card readers and a data processing center, wherein a radiated signal of each outdoor antenna unit covers a stereoscopic spatial region, the outdoor antenna units transmit data information to the electronic labels in a broadcasting manner, at least one wireless node equipment and at least one electronic card reader are arranged in each stereoscopic spatial region, the electronic card readers identify the electronic labels entering the stereoscopic spatial regions and read the data information in the electronic labels, the electronic card readers upload the data information to one Zigbee wireless node equipment and transmit the data information to the data processing center through the Zigbee wireless network, and the data processing center receives the data information and generates control commands. The wireless communication system adopts the combination of an RFID (radio frequency identification devices) technology and a Zigbee interconnecting technology, the characteristics of FRID technology detection and Zigbee interconnecting of the RFID technology and the Zigbee interconnecting technology are fully exerted, and therefore, the wireless communication system can be applied to multiple application scenes.
Description
technical field [0001] The invention relates to a communication system, in particular to a wireless communication system based on the combination of RFID technology and Zigbee interconnection network. Background technique [0002] Radio Frequency Identification (RFID) technology is an automatic identification technology that began to emerge in the 1990s. Radio Frequency Identification technology is a technology that uses radio frequency signals to achieve non-contact information transmission and A technology that achieves the purpose of identification through the transmitted information. However, radio frequency identification technology cannot carry out long-distance communication, and can only carry out point-to-point short-distance communication. [0003] Zigbee is a wireless communication IEEE 802.15.4 protocol, and the technology specified in this protocol is a short-distance, low-power wireless communication technology. It is widely used due to its advantages of low ...
