Embodiment Construction

[0018] The present invention will be further described now in conjunction with accompanying drawing:

[0019] refer to figure 1 and figure 2 , the problem to be solved by the invention is to realize the real-time monitoring of the three-dimensional velocity and navigation depth of the long-range underwater vehicle during the self-propulsion process, and realize the stability of the long-range underwater vehicle during the self-propulsion process through the control of the control center . Based on this, the present invention adopts a Doppler velocity meter to realize the above-mentioned basic functions.

[0020] Its working process is as follows: Doppler Velocimeter 6 uses sound waves to measure the three-dimensional velocity and real-time water depth of the remote underwater vehicle during self-propelled process according to the Doppler principle, and converts the data into signals and transmits them through wires. The control center 3 controls the course according to the...

Abstract

The invention discloses an installation device for a remote underwater vehicle speed measurement unit, and the device is used at a navigation control segment of a remote underwater vehicle. The device is characterized in that the device comprises a housing; the housing is provided with an opening; one end of a Doppler speed measurement unit is disposed in the housing in an inverted manner through the opening; the device also comprises a transition flange which is fixed in the remote underwater vehicle; the other end of the Doppler speed measurement unit is connected with the transition flange through a fastening part; the device also comprises a control center; the real-time monitoring of a three-dimensional speed and a navigation depth, which are measured by the Doppler speed measurement unit in an automatic navigation process, is carried out in real time, and the signals are transmitted to the control center through a signal line. The device is simple in structure, and is convenient to use.

Description

technical field [0001] The invention belongs to the technical fields of ships, marine engineering and navigation, and in particular relates to a mounting device for a speedometer of a remote underwater vehicle. Background technique [0002] Doppler Velocimeter is an instrument for measuring the speed of underwater moving bodies. During the underwater movement of the underwater vehicle, it is necessary to obtain the absolute speed of the vehicle relative to the bottom of the sea. Usually, the underwater vehicle will obtain the speed value by installing a Doppler velocity meter. The Doppler installed on the underwater vehicle will produce measurement errors due to the existence of water vapor bubbles. Contents of the invention [0003] In order to realize the real-time monitoring of three-dimensional velocity and navigation depth to the remote underwater vehicle in the process of self-propulsion, the present invention proposes the method of using the Doppler velocimeter on ...
