Material positioning system

Abstract

The invention discloses a material positioning system. The system comprises an anti-counterfeiting positioning label arranged on a material and used for adjusting the sending status of a Bluetooth signal according to the current motion state; a plurality of Internet of Things Bluetooth gateways used for receiving and parsing the Bluetooth signal, and transmitting a unique identifier of the anti-counterfeiting positioning label, the motion state, the remaining capacity and the signal intensity of the Bluetooth signal obtained by parsing to a server by means of an LPWAN (Low Power Wide Area Network); and the server used for positioning according to the signal intensity of the same Bluetooth signal received by the plurality of Internet of Things Bluetooth gateways and the positions of the Bluetooth gateways, and obtaining position information of the anti-counterfeiting positioning label that sends the Bluetooth signal. The material positioning system provided by the invention solves the problems of lower positioning accuracy, high deployment difficulty of positioning equipment and short endurance time of the positioning label and so on in the traditional material positioning scheme.

Description

technical field [0001] The invention relates to the field of warehouse management. More specifically, the present invention relates to a material locating system. Background technique [0002] With the wide application and promotion of the Internet of Things technology in the logistics system, the use of the Internet of Things technology can greatly improve the efficiency of the logistics system, and can further improve the management quality of the logistics system. The material positioning system generally includes a positioning device set on the material and a gateway device that accepts the positioning data sent by the positioning device. Today, there are three mainstream material positioning systems on the market: [0003] 1) RFID technology has the attribute of encryption, which is inherently anti-counterfeiting, but the working distance is short (passive devices are generally 10cm, and active RFID cards can only be increased to tens of meters), and the size of the an...
