Anti-counterfeiting bluetooth transmitting device with function of movement detection

Abstract

The invention discloses an anti-counterfeiting bluetooth transmitting device with function of movement detection. A bluetooth signal containing an own unique identifier is sent around based on a BLE technology; and the anti-counterfeiting bluetooth transmitting device adjusts the transmitting state of the bluetooth signal according to a current motion state, wherein the transmitting state includesa wake-up period of time of the anti-counterfeiting bluetooth transmitting device and the transmitting number of times within the unit of time. According to the invention, the cruising power with atleast three years is realized and if certain requirements are met, the cruising power with five to ten years can be realized by the device. The current state of the node is broadcasted by broadcast information and broadcasting is carried out when necessary; and the cruising power of the tag is improved. With an encryption algorithm, encryption and counterfeiting prevention of the own broadcastinginformation are realized. The compatibility with the iBeacon protocols is realized and compatibility with all iBeacon protocols and functions is high.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication. More specifically, the present invention relates to an anti-counterfeiting bluetooth sending device with a motion detection function. Background technique [0002] With the in-depth development of informatization and various intelligent terminal equipment, the demand for personnel and asset positioning continues to heat up, and the application demand in the field of location services has also shown exponential growth, such as: asset positioning in smart parks, material positioning in large warehouses, abandoned hospitals Object tracking and processing, elderly activity area positioning in nursing homes, pet positioning, etc.; [0003] There are three mainstream material positioning in the market today: [0004] 1) RFID technology, with its own encryption properties, is inherently anti-counterfeiting, but the working distance is short (passive devices are generally 10cm, and acti...

AI Technical Summary

Problems solved by technology

[0004] 1) RFID technology, with its own encryption properties, is inherently anti-counterfeiting, but the working distance is short (passive devices are generally 10cm, and active RFID cards can be increased to tens of meters), and the size of the antenna is large, which is inconvenient to deploy;

[0005] 2) UWB technology adopts TOA optical propagation method to achieve high-precision positioning and short delay. However, TOA optical propagation method requires strong computing power and algorithms to ensure accuracy, and the system complexity is high. Sensor network deployment high cost;

As an excellent product in Bluetooth positioning technology, iBeacon is a positioning beacon node launched by Apple. The iBeacon node broadcasts to the outside periodically. By detecting the broadcast transmission intensity of the iBeacon node, the distance between the beacon node and the receiving device is calculated. The distance, so as to determine the position information of the beacon, the node has been broadcasting information periodically, but only the broadcast information received within the positioning time period is useful information, and most of the other broadcast information is useless, so it has not been realized Efficient use of power consumption and broadcast signals can also cause broadcast signal pollution
