Abstract

The invention relates to a visible light communication equipment testing system, and the system can transmit a square wave electric signal to a transmitting end through a first signal generation unitin a transmission rate testing module, and analyzes a signal received by a receiving end through a first signal analysis unit, thereby obtaining the effective transmission rate of a to-be-tested visible light communication system. In a modulation performance test module, a second signal generation unit is connected with an emission light source in the visible light communication equipment to be tested; and photoelectric conversion is performed on the second optical signal emitted by the emission light source through a convergence filtering unit and a photoelectric detector, and the communication electric signal obtained through conversion is transmitted to the second signal analysis unit so that the modulation performance result of the emission light source can be obtained. By utilizing the visible light communication equipment testing system, digital quantity testing and analog quantity testing can be carried out on the visible light communication equipment to be tested, an effectivetransmission rate and a modulation performance result are obtained, and then the testing efficiency of the visible light communication equipment can be improved.

Description

technical field [0001] The present application relates to the technical field of communication testing, in particular to a visible light communication device testing system. Background technique [0002] With the development of communication technology, VLC (Visible Light Communication, visible light communication) technology has emerged. VLC communication technology can use light in the visible light band as an information carrier, without the need for transmission media such as optical fibers and other wired channels, and can directly transmit optical signals in the air. . [0003] The analog quantities between different visible light communication devices and the digital quantities between different visible light communication devices are quite different. It is necessary to test each visible light communication device separately to obtain the corresponding communication performance of each visible light communication device. At present, when obtaining the transmission ra...
