The invention relates to a real-time concurrent control system of a six-degree-of-freedom eyeball type underwater robot. The system includes a control subsystem, an image processing subsystem, a laser communication submodule and a data fusion module. The control subsystem is connected with the laser communication module and the data fusion module and realizes CAN bus high-speed communication with the image processing subsystem through a CAN converter, and the two subsystems concurrently process data, thereby realizing real-time concurrent control of the underwater robot. The real-time concurrent control system of the six-degree-of-freedom eyeball type underwater robot can solve the problem that when the underwater robot works in a severe underwater environment, due to influence of external factors such as torrential water flow and undercurrents, pose information of itself cannot be accurately measured or the underwater robot cannot communicate with the outside world and thus cannot normally pass through, and working is limited.

The invention relates to a distributed magnetic resonance underground water detection device and method. The device comprises an excitation device, a polarization device, an air receiving structure carrying an array type cold coil sensor and a detection coil to which the air receiving structure belongs. A polarization transmitter determines the positions of the polarization transmitter and the airborne receiving structure through a position analysis module and determines whether the polarization transmitter outputs the signals or not.
