Abstract

The invention discloses an ultrasonic longitudinal wave based lithosphere-state real-time detection system which comprises a micro controller module, an ultrasonic transmitting module, an ultrasonic receiving module, a display module and a power module, wherein the ultrasonic transmitting module, the ultrasonic receiving module, the display module and the power module are connected with the micro controller module, the micro controller module comprises a timing unit, a first computing unit, a second computing unit and a comparison unit, the ultrasonic transmitting module comprises a high voltage circuit, a pulse generating circuit and an ultrasonic transmitting transducer which are sequentially connected, and the ultrasonic receiving module comprises a noise filtering circuit, a receiving signal amplification circuit and a signal shaping circuit which are sequentially connected. The system disclosed by the invention can be used for monitoring the situations of surrounding-rock loosing circles in real time by using a relation among the propagation velocity of ultrasonic waves in rock masses and the stress state and cracking degree of rock masses, and is convenient, flexible and easy to operate.

Description

technical field [0001] The invention relates to an ultrasonic distance measuring system, in particular to a real-time detection system of rock layer state based on ultrasonic longitudinal waves, which belongs to the field of distance measurement. 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...
