Description
本发明涉及电子价签定位技术领域，特别涉及一种多天线的电子价签装置。The invention relates to the technical field of electronic price tag positioning, in particular to an electronic price tag device with multiple antennas.
传统电子价签主要完成显示商品价格的功能，核心系统将需要显示的信息推送到电子价签上显示，电子价签本身只有一个通信天线用于无线通信。由于大商超有实时寻找货物以及导购等业务需求，如何对大商超里的商品进行定位是一个课题。传统室内定位的方法有ibeacon、uwb和wifi指纹等。这些方案能定位的精度都在1m以上，甚至误差达到10m，不能满足密集的商品陈列定位的需求。当利用电子价签本身所在的无线通信系统进行定位时，由于电子价签的通信天线主要功能是跟AP进行通信，不能满足定位过程中需要以弱功能检测邻居的功能需求。The traditional electronic price tag mainly completes the function of displaying commodity prices. The core system pushes the information that needs to be displayed to the electronic price tag for display. The electronic price tag itself has only one communication antenna for wireless communication. As the supermarket has real-time search for goods and shopping guide and other business needs, how to locate the products in the supermarket is a problem. Traditional indoor positioning methods include ibeacon, uwb and wifi fingerprints. The positioning accuracy of these solutions is above 1m, and even the error reaches 10m, which cannot meet the needs of dense commodity display positioning. When using the wireless communication system where the electronic price tag itself is located, the main function of the electronic price tag's communication antenna is to communicate with the AP, which cannot meet the functional requirements of detecting neighbors with weak functions during the positioning process.
