Embodiment Construction
[0039] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0040] Such as Figure 1 to Figure 3 As shown, this example provides a visible light communication blind area coverage and handover method based on reflected light, including the following steps:
[0041] Step S1, the mobile smart device receives the reflected light signal from the side of the LED light to communicate;
[0042] Step S2, the mobile smart device controls the rotation of the mirror installed next to the LED light through a mobile network, so that the reflected light signal of the mirror can irradiate the mobile smart device in real time, and the mobile network is preferably a WIFI network;
[0043] Step S3, after the mobile smart device receives the reflected light signal, it performs seamless handover communication when moving through the blind area, and switches to a new LED light irradiation area. The area illum...

Provided by the present invention are a visible light communication blind area coverage and cross-regional handover method based on reflected light, comprising the following steps: step S1, a mobile intelligent device receives a reflected light signal from the side of an LED lamp in order to carry out communication; step S2, the mobile intelligent device controls a mirror that is arranged beside the LED lamp to rotate by means of a mobile network, so that a reflected light signal of the mirror may be irradiated to the mobile intelligent device in real time; and step S3, after receiving the reflected light signal, the mobile intelligent device performs seamless cross-regional handover communication when moving through a blind area and switches to an irradiation area of a new LED lamp. According to the present invention, wireless communication is implemented on the basis of the visible light in an indoor environment, and the mirror which may rotate along with the movement of the mobile intelligent device is arranged beside the LED lamp, so that an original communication blind area may be effectively covered without modifying original routes and lighting devices in the room. Thus, the implementation mode of the present invention is simple, effective, convenient and economical.
Description
technical field [0001] The present invention relates to a visible light communication coverage method, in particular to a visible light communication blind zone coverage and handover method based on reflected light. Background technique [0002] The rise of "smart home" and the rapid popularization of computers and smart devices have revolutionized the category of mobile digital terminals and brought a huge challenge to traditional access network technologies. The "last mile" dilemma of FTTH, the shortage of spectrum resources in wireless access networks, the immaturity of optical wireless communication and electromagnetic radiation all restrict the breakthrough of this bottleneck; today's world is performing a "anytime, anywhere" access The society is also calling for an access method that broadens spectrum resources, is green and energy-saving, and is mobile. As a result, visible light communication came into being. [0003] Visible light communication was born in 2000. ...
