Data Acquisition System Design of 6000m Single-Conductor Cable Transmitting CTD Profiler

The design of the data acquisition system of 6000 meter high precision CTD profiler is introduced.The ultralow-power microcontroller MSP430 is chosen as the MCU.2-CPU frame ensures the balance of high precision data acquisition and control tasks.Taking full advantage of the modules in MCU and low-power design,the system achieves the requirement while minimizing the PCB area and power dissipation.The instrument's stability and measurement precision are both reliable through the comparing experiments with import sensor system on the ocean.
