近海船舶数据采集网关设计

The Gateway Design of Offshore Ship Data Acquisition

为了解决船舶数据采集效率低、成本高、实时性差,历史数据查询难,数据统计评估不精确的问题,设计了近海船用数据采集网关。采集网关以STM32F103VET6为主控芯片,通过RS485通信串口连接船上各传感器,配合北斗/GPS模块实现数据采集,应用GPRS(general packet radio service)无线传输技术实现网关与终端服务器的数据传输。实际测试显示,用户可通过PC或移动终端实时了解船舶工况,可为近海航行船舶提供重要的安全保障。

Due to the disadvantages on currently on board data acquisition systems in terms of efficiency,cost,time,querying historical data and data statistics assessment,an offshore ship data acquisition gateway was presented in this paper. The acquisition gateway used STM32 F103 VET6 as the main control chip,and data collection was realized by the gateway RS485 communication serial ports connecting various sensors on board a ship. The gateway was further cooperated with Beidou/GPS module,and the data transmission between gateway and terminal server was achieved by GPRS wireless transmission technology. Results from practical tests show that users can much conveniently and accurately learn about information about the ship＇s sailing situation through PC or mobile terminal,which can also provide important security assurance for the offshore navigating ships.
