The system made by the technology can cover the range of indoor lighting, and the computer does not need to be connected by wires, so the system has wide development prospect. Wherein, the visible light is the part which can be perceived by human eyes in the electromagnetic spectrum, and the visible spectrum has no precise range; the wavelength of electromagnetic waves that can be perceived by the eye of an average person is between 400 nanometers and 700 nanometers, but some people can perceive electromagnetic waves having wavelengths between about 380 nanometers (789 THz) and 780 nanometers (385 THz). Compared with a currently used wireless local area network (wireless LAN), the visible light communication system can use indoor lighting equipment to transmit signals instead of a wireless LAN base station, and the communication speed can reach tens of megabits per second to hundreds of megabits per second, and the transmission speed in the future can exceed the optical fiber communication. The computer and the mobile information terminal which are special and can receive and send signals can download and upload data such as high-definition pictures, animation and the like for a long time only in a place illuminated by indoor light, but the limitation also exists, the lighting device is required to be used as a carrier of a relay, and no signal exists when no lighting device is used. As for the research and development results of the visible light communication technology, for example, chinese patent CN104539361A discloses a method for adjusting the illumination range in indoor visible light communication and a lighting device, which mainly focuses on the technical effect of adjusting the illumination range of the lighting device along with the movement of an indoor terminal under the condition that the maximum power of the lighting device is not exceeded, and the lighting device includes a signal receiving module, a monitoring module and an illumination radius adjusting module. Further, patent EP3324557a1 discloses a luminaire with different visible light communication capabilities, only with a view to improving how better visible light communication is utilized, and lacks flexibility, and further, for example, patent US9847835 discloses a lighting device for visible light communication with a receiver including an image sensor, the improvement being in how the time for receiving an identification light signal is shortened, and the problem of light concentration being low over a certain distance based on visible light blockage, resulting in a reduction of the light signal, has not been solved at all times.
There are many practical problems to be solved in the field of visible light communication of lighting devices, and no specific solutions have been proposed.

the lighting control module sends the information that the most edge quadrant region is occupied to the intelligent lighting device close to the most edge quadrant region, and the lighting control module further comprises:
after the intelligent lighting device close to the most edge quadrant area receives the information that people exist in the most edge quadrant area, lighting is automatically started according to the information;
the lighting control module is further stored with lighting device marking information of intelligent lighting devices which are adjacent to the edge-most quadrant region of the lighting space one by one, when the fact that a person is in the edge-most quadrant region is confirmed, the lighting control module acquires the lighting device marking information of the adjacent intelligent lighting devices according to the edge-most quadrant region information, and sends information including the fact that the person is in the edge-most quadrant region according to the lighting device marking information.
