Embodiment Construction
[0014] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0015] In the embodiment of the present invention, an optical communication device is installed in a confined space that cannot receive wireless communication signals. The optical communication device receives an optical communication signal emitted by a mobile phone through an LED lamp, decodes the optical communication signal into a communication signal, and converts the communication signal. The signal is transmitted to the communication base station, realizing the purpose of wireless communication in a confined space that cannot receive wireless communication signals.

The invention is suitable for the field of light emitting diode (LED) optical communication, and provides an urgent communication method and an urgent communication system through a mobile phone light emitting diode (LED) lamp. The method includes the fowling steps: an LED optical communication device is arranged in a sealed space which can not receive wireless communication signals; a mobile phone provided with the LED optical communication device generates optical communication signals, and sends the optical communication signals to the LED optical communication device; the LED optical communication device receives the optical communication signals sent by the mobile phone and decodes the optical communication signals and then sends out the decoded optical communication signals. The optical communication device is arranged in the sealed space which can not receive the wireless communication signals, receives the optical communication signals sent by the mobile phone through the LED lamp, decodes the optical communication signals into communication signals, and sends the communication signals to a communication base station. Therefore, the purpose of realizing wireless communication in the sealed space which can not receive the wireless communication signals is achieved.
Description
【Technical Field】 [0001] The present invention relates to the field of LED optical communication, in particular to a method and system for emergency communication through mobile phone LED lights. 【Background technique】 [0002] Confined spaces such as tunnels, mines, and elevators are blind spots for wireless communication, and wireless signals often cannot be transmitted to the confined spaces. The above spaces are often prone to accidents: traffic accidents often occur in tunnels, and if wireless communication is not possible, accidents cannot be reported in time; mines are prone to mine disasters, if wireless communication is not possible, you cannot contact the ground in time for rescue . Therefore, wireless communication in a confined space is an urgent need to solve a matter of life safety. [Content of the invention] [0003] The purpose of the embodiments of the present invention is to provide a method for emergency communication through mobile phone LED lights. It aims ...
