Shore base simulation platform system based on seafloor observatory network

The invention discloses a shore base simulation platform system based on a seafloor observatory network. The shore base simulation platform system is built according to the actual conditions of a seafloor observatory network framework, a cable actual parameter, a breakdown generation mode, an operating condition and the like. The shore base simulation platform system comprises a shore base power supply, 7n impedance analog circuits wherein n is between 1-3, node switch devices, a main junction box, a secondary junction box and an artificial load. Every seven impedance analog circuits are in a group, the node switch devices can be accessed between every two groups of impedance analog circuits, and output ends of the node switch devices are sequentially connected with the main junction box and the secondary junction box. The shore base simulation platform system can be used for simulation test of the transmission mode, power transmission characteristic, cable influence, power distribution structure, load condition, breakdown diagnosis and the like of devices of the seafloor platform before the devices enter into water, and verifying the adaptability and improving the reliability, and thus has great significance to a seafloor platform which can not be maintained frequently, promotes the seafloor observatory network to be further developed and deepened, and prolongs the service life.
