Abstract

The invention discloses an ultrasonic-based lithosphere state real-time monitoring system. The system comprises a micro-controller module as well as an ultrasonic transmission module, an ultrasonic receiving module, a rock concentration detection module, a display module, an alarm module and a power module which are connected with the micro-controller module, wherein the micro-controller module comprises a computing unit, a comparison unit and a control unit; the ultrasonic transmission module comprises a high-voltage circuit, a pulse generation circuit and an ultrasonic transmitting transducer which are sequentially connected; the ultrasonic receiving module comprises a noise filtering circuit, a receiving signal amplification circuit and a signal shaping circuit which are sequentially connected. According to the ultrasonic-based lithosphere state real-time monitoring system, the condition of the loose range of surrounding rocks is monitored in real time by utilizing the propagation speed of the ultrasonic wave in rock mass and the relation between the stress state and the cracking degree of the rock mass. The system is convenient, flexible and easy to operate.

Description

technical field [0001] The invention relates to an ultrasonic ranging system, in particular to an ultrasonic-based real-time monitoring system for the state of rock formations, which belongs to the field of ranging. Background technique [0002] Ultrasound is a kind of mechanical vibration in elastic medium, which is caused by the vibration source in contact with the medium, and its frequency is above 20kHz. Since the speed of ultrasonic waves is much smaller than the speed of light, its propagation time is easier to detect, and it is easy to directional emission, with good directionality and good intensity control, so the use of ultrasonic ranging is very important in many distance detection applications. Including non-destructive testing, process measurement, robot measurement and positioning, and fluid level measurement, etc. [0003] The safety support of the roadway plays an important role in the safety production of coal mines, and it is also a difficult point in the ...
