2、 Marine Data Collection and Transmission System based on Lwip Protocol Hui Wang Wenyu Cai Abstract Due to the status quo that serial data transmission capacity cannot meet the demand of marine environment real-time detection in the marine data acquisition system. This paper designs and implements
3、a faster Ethernet data transmission system, which can be connected with each other by Interconnection device. For the system based on single node, it consists of sensor modules, processing board. The latter constitutes of STM32F107VC processor, a lightweight LwIP protocol stack based on it. By means
4、 of transplanting LwIP protocol stack into processer, we implemented a two-way data transmission system between serial data and Ethernet data in application layer. In our measurements, we choose different frame lengths from 100 to 500 bytes as variable; by comparisons, we find that transferring rate
5、 through Ethernet is superior to RS232 RS485 CAN bus from 100 bytes to 500 bytes which meets the design requirement. Keywords-Data Collection; LwIP ; TCP/IP; Data Transmission. I INTRODUCTION In recent years, Marine data collection and transmission system (MDCATS) regarding seafloor observatory node
6、s as the carrier can realize the real-time, automatic acquisition of water environmental monitoring data below sea level. It consists of various sensors, CPU controller, data transferring interface, and remote monitoring platform. At the same time, it could provide a wealth of information on ocean exploration and monitoring. From the beginning of developing marine data acquisition and monitoring system to n
