Title: Overwater deployment and recovery monitoring system for deep-sea mining collector
Inventor: TANG JUN
IPC: E21C50/00

Abstract: The present disclosure provides an overwater deployment and recovery monitoring 
system for a deep-sea mining collector, including an integrated monitoring subsystem and a 
control subsystem. The integrated monitoring subsystem includes a multi-screen monitoring 
console, a sensor, and a subsystem measurement and control station. The sensor and the 
subsystem measurement and control station collect and monitor data and transmit the data and 
obtained monitoring information to the multi-screen monitoring console; and the multi-screen 
monitoring console receives and displays the data and the monitoring information. The 
control subsystem includes a main console, a core control level, and a field control level. The 
main console implements operation, control and display of control information, the core 
control level controls electric motors and hydraulic devices, and the field control level 
receives the control information and controls all other devices except the electric motors and 
the hydraulic devices. The present disclosure proposes a deployment and recovery operation 
scheme for a marine mining system, which better solves actual problems of marine 
deployment and recovery of a long pipeline system for marine mining.
