为满足高速光无线传输在高校高速数传实验场景下的应用需求,研制了高速光无线传输仪器,并实测了其性能。该仪器主要由包含了IP175GHR芯片的介质转换模块和CS6721三合一智能芯片为主控芯片的光模块组成,具有体积小、成本低、可靠性高等特点。提出了一种适用于全温度范围内的消光比算法,能够在长距离传输和温度变化较大环境下保持光功率稳定。根据所选的微控制单元(MCU)特性,设计了3种下位机软件程序。经实验测试:该高速光无线传输仪器具有稳定、快速的数据传输能力,且在多数场景下可快速建立光无线传输链路,能较好地应用于光无线传输实验教学场景。
To satisfy the application requirements of high-speed optical wireless transmission in collegial high-speed data transmission teaching experiment,a high-speed optical wireless transmission instrument is developed,and its performance is evaluated in this paper.The instrument consists of a dielectric conversion module with an IP175GHR chip and an optical module of CS6721,which is a three-in-one intelligent chip,as the main control chip.It has the advantages of small size,low cost and high reliability.Based on the above hardware,an extinction ratio algorithm suitable for the whole temperature range is also proposed.It can maintain the stability of light power in the environment of rather long distance transmission and large temperature transition.Finally,three client software programs are designed according to the characteristics of microcontroller unit(MCU).The test results show that the high-speed optical wireless transmission instrument has stable and fast data transmission ability,and it can quickly establish transmission link in most scenarios.In addition,it can be well used in experimental teaching related to optical wireless transmission scenarios.
