Embodiment Construction

[0026] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0027] The embodiment of the present invention provides a signal transmission method. The signal transmission method of this embodiment mainly realizes that the receiver can only receive the transmitted signal from one LED lamp at a time by controlling multiple LED lights to emit light signals one by one. This avoids the fact that the receiver is likely to receive interference signals transmitted by non-target LED lights due to simultaneous signal transmission of multiple LED lights in the prior art, and solves the problem that the prior art uses LED lights for signal transmission that easily cause transmission The problem of errors has achieved the effect of avoiding signal interference a...

Abstract

The invention discloses a method and a device for signal transmission. The method for the signal transmission comprises steps of controlling a plurality of light emitting diode (LED) lamps to transmit light signals in sequence. By the aid of the method and the device, the problem of the error of transmission when LED lamps are used for transmitting signals in the prior art is solved. The signal interference is avoided and the signal transmission accuracy is improved.

Description

Technical field [0001] The present invention relates to the field of optoelectronics, in particular to a signal transmission method and device. Background technique [0002] When the existing LED lights on the ceiling are used as transmitters and the light signals generated by the LED lights are used as the propagation carrier for signal transmission, because there are more LED lights on the ceiling and the distance between the LED lights is relatively close, When the signal is transmitted, these LED lights will send out signals. When the receiver is receiving signals, it will not only receive the signal transmitted from the target LED light, but also receive the signal transmitted from the non-target LED light. Interference signal, in this case, the signal received by the receiver will be inaccurate, and the signal cannot be transmitted normally. [0003] Regarding the problem of easily causing transmission errors when using LED lights for signal transmission in related technolog...
