摘要
随着信息及数据挖掘技术的发展,船舶装备各类传感器来采集分析数据。数据最终通过RS-232标准串口通信协议传输至数据中心,由于海上特殊的气候环境及带宽限制,船舶串口通信传输效率较低、误码率较高。本文对传统的stm32控制器为核心的串口通信协议栈进行优化,使软硬件能够更好协同进行数据转换及传输,有效提高了船舶通信效率。
With the development of information and data mining technology, ships carry various sensors to collect and analyze data. The data center is transmitted through the RS-232 standard serial communication protocol. Because of the special environment and bandwidth limitation at sea, the transmission efficiency of the serial port communication is low and the bit error rate is high. This paper optimizes the serial communication protocol stack with STM32 controller as the core, so that the software and hardware can better coordinate the data conversion and transmission, and effectively improve the efficiency of the ship communication.
