The invention provides a UUV(
Unmanned Underwater Vehicle) navigational speed duplex control device and method for
ocean observation operation, which comprises a
task control module, a magnitude navigational speed
control channel, a precise navigational speed
control channel, a
motion control module and a sensing module, wherein the
task control module is mutually connected with the magnitude navigational speed
control channel, the precise navigational speed control channel, the
motion control module and the sensing module, and the magnitude navigational speed control channel and the precise navigational speed control channel are all connected with the
motion control module. The sensing module captures UUV status, position information and
ocean current section information, and then sends the UUV status, the position information and the
ocean current section information to the
task control module, the motion control module and the task control module to carryout real-
time information exchange after the information is processed. The task control module selects different channels according to the current operating condition, and sends
digital control quantity corresponding to the current navigational speed command of UUV to the motion control module in order to accomplish the entire navigation speed control procedure. The UUV (
Unmanned Underwater Vehicle) navigational speed duplexcontrol device and method disclosed by the invention can be applied for cable control debugging and navigational speed control of various kinds of UUV (
Unmanned Underwater Vehicle) during multiple-operation condition operation.
