摘要
描述了一个利用LED实现的星内光无线CAN通信系统。通过光收发电路代替有线CAN通信的收发器部分,实现了基于LED的光无线CAN通信。所实现系统在器件选用、功耗等方面尽可能考虑了在轨应用可行性。实验结果表明,所实现基于LED的星内光无线CAN通信系统在漫反射通信状态设备间距离为0.5 m时,通信速率最高可达100 kb/s,可应用于卫星内部特定载荷之间的CAN通信。
In the paper, an intra-satellite optical wireless communication system based on LED is proposed. To achieve the function of optical wireless communication, the system uses the circuit of light receiver and transceiver instead of the transceiver chip. The system makes the choice of the devices and reduces the power consumption, considering the feasibility of the application of satellite in orbit as much as possible. The experiment results show that the speed of the system is up to 100 kb/s, when the distance between the two devices is 0.5 m. The system can be used in the intra-satellite wireless CAN communication between the specific equipments.
