PPM pulse type laser communication device and method based on serial port protocol

The invention discloses a PPM pulse type laser communication device and method based on a serial port protocol, belongs to the technical field of laser communication, and particularly relates to PPM pulse type laser communication based on the serial port protocol. The problem that an existing laser communication system is small in communication bandwidth is solved. The device comprises the following modules: a laser coding output module used for carrying out PPM modulation on source data to obtain PPM return-to-zero pulse data and sending the PPM return-to-zero pulse data to the outside; and the laser decoding module is used for decoding non-return-to-zero serial port protocol format data in the source data according to the PPM return-to-zero pulse data. The PPM pulse type laser communication device and method based on the serial port protocol are suitable for laser communication. 基于串口协议的PPM脉冲式激光通信装置及方法，属于激光通信技术领域，尤其涉及一种基于串口协议的PPM脉冲式激光通信；解决了现有激光通信系统所存在的通信带宽较小的问题；所述装置包括以下模块：激光编码输出模块，用于对源数据进行PPM调制，获得PPM归零脉冲数据，并
