基于敏感测温点的浮标舱温监测系统设计

为监测海洋资料浮标的舱温变化,设计了一种基于敏感测温点的浮标舱温监测系统。利用单总线和寄生电源供电技术,将温度传感器布设在浮标内部多个测温点,组成舱温监测网络,然后挂接到浮标采集系统的核心单元微控制器(MCU)上,只占用一个I/O口线实现对浮标多个测温点的实时监测。海试结果表明,该系统可用于对大型浮标舱温的网络化监测。

Sensitive temperature points based design of buoy tank temperature monitoring system

We design a sensitive temperature points based buoy tank temperature monitoring system to monitor the tank temperature of a ocean data buoy.We deploy multiple temperature sensors at multiple temperature points in a buoy with single wire bus and parasitic power supply technology,which constitute a tank temperature monitoring network.They are then connected to the MCU of the buoy data collecting system.The network only occupies one I/O port to achieve realtime monitoring for multiple temperature points.Marine tests show that the system can implement network monitoring for the tank temperature of a large-scale buoy.
