Development of visible light communication equipment receiving performance analyzer

可见光通信(Visible Light Communication,VLC)设备是当前的研究热点,其接收性能是VLC设备通信关键的评价指标之一,现仍缺乏检测VLC设备接收性能的相关仪器。该文从VLC设备接收性能参数检测需求出发,研制可见光通信设备接收性能分析仪。在原有分析仪工作机理基础上改进仪器的光路与工作机理,建立照度探测器上光照度与VLC接收端光照度的等效关系,提高装置自动化水平与检测效率;对仪器进行精度设计,得出相对较佳精度分配方案。实验表明:所研制的可见光通信接收性能分析仪可自动、高效地检测VLC设备的最小接收照度值、最大接收照度值两个参数。

Visible light communication( VLC) equipment is a research hotspot at present,and the reception performance is one of the key evaluation indexes of VLC equipment communication. However,there is still a lack of relevant instruments to test the reception performance of VLC equipment. Based on the demand of VLC equipment receiving performance parameter detection,this paper develops a receiving performance analyzer for VLC equipment. On the basis of the original working mechanism of the analyzer,the optical path and working mechanism instrument are improved,and the equivalent relationship between the illumination on the illuminance detector and the illumination on the VLC receiver is established,so as to improve the automation level and detection efficiency of the analyzer. The instrument precision is designed and a relatively good precision distribution scheme is obtained. The experimental results show that the analyzer can automatically and efficiently detect two parameters which are minimum illumination maximum illumination of VLC equipment and the measurement accuracy meets the requirements.
