Enhanced Safety Control and Self-Rescue System Applied in AUV
Thousands of AUVs are working in scientific research, commercial offshore and military application. As we known, most of the AUV are expensive. We must adopt active and passive safety methods prevent AUV lost. More than 50％ of AUV lost cases are power supply accident. Once the AUV lost main power, it will sink into the sea bottom in the end. Active safety measures should be takeout before the accident happened. Energy supply is the most important factor to ensure patrol mission accomplished. Active safe measures include battery terminal voltage monitoring, internal resistance checking, charge/discharge monitoring, ambient temperature compensation, residual capacity estimate. Power supply system is arranged by these methods, battery group is charged well and full, battery never be over charged or discharged, and malfunction be avoided by battery defect detection and replacement in advance. The AUV designed in this paper working in a lake, it maybe wrapped by broken fishing net. Passive safe measures are necessary, include dual power supply system, backup battery and rescue balloon to force the AUV surface up. Expensive instruments lost are prevented by these measures.
