Problems solved by technology
However, the developed marine positioning and tracking systems are all based on engine power supply. Once an accident occurs on the ship and the engine and the entire power system fail, the positioning and tracking system will also lose its expected function.
In addition, the existing marine positioning and tracking systems are all external, and cannot work normally when the ship is in a wreck or flooded, or when the ship is hijacked by criminals and the positioning and tracking system is turned off

Description
technical field [0001] The invention belongs to the technical field of new energy, and specifically relates to a piezoelectric-friction-electromagnetic composite vibration generator, which is used for power supply of a ship positioning and tracking system, and can also be used for collecting vibration energy with multi-directional vibration characteristics such as simple ocean waves and vehicles. Background technique [0002] The development and application of civil ship positioning and tracking system has gradually gained more and more attention. Its popularization and application will provide a strong guarantee for the ship's navigation safety, timely rescue, and search after losing contact. However, the developed marine positioning and tracking systems are all based on engine power supply. Once an accident occurs on the ship and the engine and the entire power system fail, the positioning and tracking system will lose its expected function. In addition, the existing posit...
