Abstract

The present invention discloses an LED indoor positioning and transmitting system. The system comprises an LED lighting module server and a central control unit CPU server. A front end of the LED lighting module server is provided with an LED lamp server, the LED lamp server is nested and arranged in the LED lighting module server, a light sensation collector server is arranged on the outer side of the LED lamp server, and the light sensation collector server is electrically connected to the LED lamp server. The light sensation collector server and the server are used to perform the operationof a transmitting system. The algorithm is simple and dedicated reference nodes are not needed to perform redeployment to facilitate running of a positioning and transmitting system, a transmitting system monitor is employed to real-time monitoring of the positioning and transmitting system to avoid being stolen, the LED indoor positioning and transmitting system is suitable for accurate positioning of indoor large-scale shopping malls, internal portions of buildings, underground shopping malls, underground parking lots and the like, and an optical receiver and a LED coding program instrumentare employed to solve the problems that LED lamps for positioning and receivers are complex in structure, high in cost and difficult in deployment.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an LED indoor positioning and transmitting system. Background technique [0002] With the increasing demand for indoor positioning and navigation services in recent years, the realization of low-cost, high-precision indoor positioning has become more and more important in practical significance. At present, the commonly used indoor positioning technologies are Bluetooth, ZigBee, ultra-wideband, RFID and other positioning schemes have algorithms based on Time of Arrival (TOA), Time Difference of Arrival (TDOA), Received Signal Strength Indication (RSSI), fingerprint and other positioning algorithms. However, these positioning schemes have disadvantages such as difficult deployment, complex equipment, and high cost. Due to these shortcomings and the development of visible light communication technology in recent years, foreign researchers have begun to propose indoor positionin...
