2.4G frequency band signal transmitter

Abstract

The present invention relates to the field of wireless communication technology, in particular to a 2.4G frequency band signal transmitter, including a beacon main chip, a beacon antenna circuit, a beacon key circuit, a beacon PWR circuit, a beacon antenna circuit, The button circuit of the beacon and the PWR circuit of the beacon are connected to the main chip of the beacon. The PWR circuit of the beacon is used to provide power supply for the main chip of the beacon, and the button circuit of the beacon is used to start configuration and sleep 2.4G Frequency band signal transmitter. The invention has a simple structure, no complicated circuit carrying logic, and through the PWR circuit of the beacon device, the energy consumption is far lower than that of similar products, and the battery needs to be replaced only after about 3 years of use; the overall volume is small, easy to integrate, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a 2.4G frequency band signal transmitter. Background technique [0002] At present, electronic beacons, RFID beacons, infrared sensors, etc. are usually used to realize the perception of the Internet of Things in the exhibition center, exhibition hall or inside the company. Due to hardware constraints, these electronic products cannot communicate with smartphones, so they cannot develop software products based on mobile terminals. And out of green environmental protection, information security, intelligent perception and other needs. There is an urgent need in the market for a beacon with low power consumption, small size, low price, and the ability to transmit signals that can be received by smartphones. [0003] Defects and deficiencies of the prior art: [0004] High cost: similar Bluetooth anti-lost devices on the market, active RFID beacons have high cost a...

AI Technical Summary

Problems solved by technology

[0004] High cost: similar Bluetooth anti-lost devices on the market, active RFID beacons have high cost and price, and the sales price of finished products is higher;

[0005] Complex structure: similar products on the market have complicated circuit design, many buttons, and the hardware itself carries many functions;

[0006] High energy consumption: similar products on the market need to replace the battery in about one year under the same battery power supply;

[0007] Poor compatibility: Products on the market usually only support one communication protocol, which is different from mainstream

[0008] Smartphone, WIFI device communication is limited
