Embodiment Construction

[0036] Visible light is the part of the electromagnetic spectrum that can be perceived by the human eye. The visible spectrum has no precise range. It is generally believed that the wavelength range of visible light is between 350 and 770 nanometers. Visible Light Communication technology (Visible Light Communication, VLC) is the use of visible light sources such as fluorescent lamps or light-emitting diodes to transmit information through high-speed bright and dark flashing signals invisible to the naked eye. Simply put, it is light communication. Connect the high-speed Internet cable device to the lighting device, plug in the power plug and use it.

[0037] Visible light communication technology has the following characteristics:

[0038] 1. Single point high speed. As of 2014, the highest peak rate of offline processing of visible light communication is 5.6Gbps created by the Italian team using red, green, blue and yellow four-color LEDs through wavelength division multipl...

Abstract

The invention provides a monitoring system and monitoring method based on visible light communication. The monitoring system based on visible light communication includes visible light communication light sources and a wearable optical receiver, wherein the visible light communication light sources are arranged in a monitoring place for emitting optical signals with positional information; and the wearable optical receiver is worn on a monitoring target for receiving the optical signal and converting the optical signals into electric signals. The monitoring system based on visible light communication does not acquire images of the monitoring target, and can obtain the action track of the monitoring target through visible light communication, thus being suitable for the places requiring privacy protection, such as a hotel, a dressing room and a bathroom. Besides, in the monitoring place, the range that the visible light can reach can be monitored, so that the monitoring blind angles of the monitoring system based on visible light communication are less, so that monitoring becomes relatively more effective.

Description

technical field [0001] The present invention relates to the technical field of monitoring, in particular to a monitoring system and a monitoring method based on visible light communication. Background technique [0002] The existing monitoring system usually arranges a camera device in the monitoring place for monitoring. Since the camera device obtains the movement track of the monitoring target by obtaining the image of the monitoring target, it is not suitable for some places that need to protect privacy, such as hotels, bathrooms, etc. , dressing room, etc. And installation of camera also has shortcomings such as monitoring dead angle. Contents of the invention [0003] In view of this, the present invention provides a monitoring system and monitoring method based on visible light communication, which are used to solve the problems that existing monitoring systems using camera devices are difficult to adapt to special monitoring places and have monitoring dead spots. ...
