specific Embodiment

[0025] Such as figure 1 As shown, it includes control chassis, cables, high-precision stepping motor, high-sensitivity angle sensor and high-speed three-dimensional sonar sensor. Other components are controlled by the control cabinet through cables.

[0026] Include steps:

[0027] (1) The control box sends control commands to the angle sensor and sonar sensor through the cable, and the angle sensor rotates according to the received command (it can rotate 360°), while the sonar sensor emits sound signals and receives the reflected sound signal, and then transmit the received signal back to the control box through the cable;

[0028] (2) The control box filters the returned sound signal to obtain a real and useful signal, and the real signal is converted into image information after being processed by the distance measurement control software;

[0029] (3) After obtaining a plane image, control the chassis to adjust the height of the sonar sensor as required, and repeat step...

Abstract

The invention discloses a sonar detection device for a three-dimensional space of a mine gob. The sonar detection device comprises a control case and a stepping motor, wherein an output shaft end of the stepping motor is connected with a sonar sensor through an angular sensor, the control case is respectively connected with the stepping motor, the angular sensor and the sonar sensor through cables. The sonar sensor emits and receives a sound signal, a true signal can be obtained by filtering the sound signals, and is processed by ranging control software, and finally a three-dimensional simulation image under the underwater environment can be displayed on a screen. The sonar detection device is low in cost, good in effect, and convenient and fast, the underwater environment information can be conveniently detected, and the sonar detection device is especially applicable to detection of the information on the three-dimensional space of the mine gob.

Description

technical field [0001] The invention relates to a three-dimensional space detection technology for a mine goaf, in particular to a three-dimensional space sonar detection device for a mine goaf. Background technique [0002] Sonar is a tool that uses sound for detection. It is an electronic device that uses sound waves in water to locate, locate and communicate with underwater targets. It is the most widely used and most important device in underwater acoustics. [0003] When observing and measuring in water, only sound waves are most suitable. This is because the action distance of other detection methods is very short, and the penetration ability of light in water is very limited. Even in clear sea water, people can only see a few Objects within ten meters; electromagnetic waves also attenuate quickly in water, and the longer the wavelength, the faster the attenuation; however, the attenuation of sound waves is much slower when propagating in water, and low-frequency sound...
