The invention relates to a ship collectivizing supervisory 
system which has the function of automatically changing the Beidou 
Satellite communication mode and the GPRS 
wireless network communication mode and can achieve the data interaction between a ship-mounted terminal and a group supervisory center based on the two communication 
modes. The ship-mounted terminal is installed on a ship body, a 
solar cell panel is adopted in a power supply subsystem for charging a 
lithium battery and a standby battery, and the terminal can reliably work for a long time without an external power source. The GPS information of a ship is stored in real time, and a 
communication unit is utilized for returning the information of a GPS, alarming and the state of the ship-mounted terminal and the like to the group supervisory center. A 
software service platform of the supervisory center combining with a GIS 
system visually displays and manages the supervised ship in a unified mode. The ship collectivizing supervisory 
system solves the problems that a communication dead zone exists in an ordinary mobile equipment 
open sea monitoring and equipment cannot work continuously for a long time, the ship collectivizing supervisory system is suitable for collectivizing monitoring of 
fishing boats and other ships, shipping is convoyed, and the supervising strength and efficiency of 
fishery administration are improved.
