A filter processing system based on broadcast power of Bluetooth indoor positioning technology

Abstract

The invention discloses a filter processing technology for broadcast power based on the Bluetooth indoor positioning technology, which includes a Bluetooth chip board, a signal detector is arranged at one end of the Bluetooth chip board, a broadcast power amplifier is arranged at the other end of the Bluetooth chip board, a signal controller and a signal detector. The broadcast power amplifiers are all connected to the power supply module. The inside of the signal detector is equipped with a radio frequency device for processing bands. The signal detector is connected to the signal processing power amplifier module through a filter. One end of the broadcast power amplifier is equipped with a player, and the other end of the broadcast power amplifier is set There is a voltage stabilizer, and the processing and analysis unit of the broadcast power amplifier is used to obtain the spatial coordinate position of the Bluetooth device. One side of the processing and analysis unit is provided with a serial number processing unit for processing and analyzing the serial number of the Bluetooth device. After receiving the sound wave, the receiving end It is a good innovative solution to convert it into interactive signaling and search for pairable Bluetooth devices based on interactive beliefs. The Bluetooth signal range is accurately positioned and the design is novel.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a filter processing technology based on broadcast power of Bluetooth indoor positioning technology. Background technique [0002] Bluetooth is a wireless technology standard that enables short-distance data exchange between fixed equipment, mobile equipment, and building personal area networks (using UHF radio waves in the ISM band of 2.4-2.485GHz). Bluetooth technology was originally created by telecommunications giant Ericsson in 1994 as an alternative to RS232 data lines. Bluetooth can connect multiple devices and overcome the problem of data synchronization. Today, Bluetooth is managed by the Bluetooth Special Interest Group. The Bluetooth SIG has more than 25,000 member companies around the world. They are distributed in multiple fields such as telecommunications, computers, networks, and consumer electronics. The Bluetooth SIG is responsible for overseeing the devel...

Problems solved by technology

[0004] Since the transmission power of Bluetooth 4.0 technology is not stable now, the power received by different mobile devices is also different, and the Bluetooth signal at the frequency of 2.4Hz is also particularly vulnerable to being blocked by the human body, so the original RSSI is almost unusable. Insufficient, unable to meet the needs of development
