Abstract:

      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 realtime monitoring for multiple temperature points. Marine tests show that the system can implement network monitoring for the tank temperature of a largescale buoy.

Key words: sensitive temperature points, buoy, tank temperature, monitoring system
