Problems solved by technology

This method is easy to solve problems such as punching or missing cards, and requires absentees to carry extra radio frequency cards with them. At the same time, because the radio frequency cards are always emitting electromagnetic waves, the damage to the human body is inevitable.

Abstract

The invention discloses an identity recognition system based on white-light communication, and particularly relates to an identity recognition system and an identity recognition method both based on an LED miner's lamp in a mine. The identity recognition system comprises a lithium battery, an emission encoder, a driver, an LED lamp holder, a blue light filter, a photoelectric detector, an amplification filter, a decoder and a communication interface. Hardware equipment of the system includes an LED miner's lamp tag and a white-light card reader. The carry-on LED miner's lamp is utilized, a controller controls the LED lamp holder to transmit identity information according to certain codes by means of a Manchester pulse coding mode, and thus, automatic identity recognition of a miner can be realized. The system has the advantages that additional active or passive identity recognition cards are not needed, identity recognition is realized by existing LED miner's lamps, and the system is easy to upgrade and free from electromagnetic radiation, does not occupy existing communication channels, does not need an additional power source, is not easy to lose, long in service, convenient to carry, low in error rate, high in communication speed and low in power consumption and the like.

Description

technical field [0001] The invention relates to an identification system, in particular to an identification method for an LED miner's lamp based on white light communication, which is suitable for underground coal mines. Background technique [0002] At present, LED white light is developing rapidly, and the technology in various fields of lighting and communication tends to be mature. Compared with other heat-generating light sources or gas discharge light sources, LED lighting is a new type of solid-state light source with high energy utilization rate, good stability and consistency, fast response speed, energy saving, and no pollution. [0003] In the attendance, tracking, positioning, and disaster relief of underground personnel in coal mines, the RFID (identification information) cards carried by miners are the most important information acquisition and management methods. At present, the identification and attendance of underground personnel mainly rely on RFID passi...
