Abstract

The invention discloses a temperature-compensation ultrasonic surface wave-based lithosphere state real-time detection system, which comprises a micro-controller module, an ultrasound transmitting module, an ultrasound receiving module, a display module, a temperature sensor and a power supply module. The ultrasound transmitting module, the ultrasound receiving module, the display module, the temperature sensor and the power supply 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 ultrasound transmitting module comprises a high-voltage circuit, a pulse generating circuit and an ultrasonic transmission energy transducer, wherein the high-voltage circuit, the pulse generating circuit and the ultrasonic transmission energy transducer are sequentially connected. The ultrasound receiving module comprises a noise filtering circuit, a received signal amplification circuit and a signal shaping circuit, wherein the circuits are sequentially connected. According to the invention, based on the relationship between the propagation velocity of ultrasonic waves in a rock, the bearing state of the rock, and the fracture degree of the rock, the loose- range condition of the surrounding rock mass can be monitored in real time. Therefore, the system is convenient, flexible, and easy to operate.

Description

technical field [0001] The invention relates to an ultrasonic ranging system, in particular to a real-time detection system of rock layer state based on temperature-compensated ultrasonic surface waves, belonging 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 d...
