The invention provides a ship mooring remote control device. The device comprises a master control module, a controlled end and a wireless communication module, wherein the controlled end is arranged on a ship and comprises a ship position and windlass environmental parameter detection module, an image acquiring and processing module and a windlass drive module. The invention also provides a ship mooring remote control method. In the method, the ship mooring remote control device is utilized, and the method comprises an input step, a transmitting step, a receiving step, a controlling step and an execution step. By the device and method provided by the invention, mooring control out of 1km is realized by selecting a proper modulation mode and transmission power, and the effective distance can be flexibly regulated according to the distance of a target, so that an operator can control mooring operation without boarding the ship, the working state and working environment of the above-water part of the mooring system can be acquired in real time through a digital camera, working condition information of the windlass of the controlled end can be monitored, and timely regulation on mooring operation can be carried out according to specific conditions, such as wind direction, wind speed, wave and the like.
