Description

Multifunctional ultrasonic range finder suitable for mining field

Technical Field

The utility model belongs to the technical field of ultrasonic detection, especially, relate to a multi-functional ultrasonic ranging appearance suitable for mining industry field.

Background

The ultrasonic wave is a sound wave with the frequency higher than 20KHz, is a mechanical wave, has strong penetrability, better directivity and small sound energy loss in the propagation process, can well transmit sound energy and has longer propagation distance. Ultrasonic waves are widely used for distance measurement in the measurement field, and are widely applied in the fields of industrial measurement, safety early warning, robot science obstacle avoidance and the like due to the advantages of a non-contact measurement mode, low cost, easiness in operation, rapidness in measurement and the like. The non-contact ranging method mainly comprises laser ranging, microwave radar ranging, infrared ranging and ultrasonic ranging. The laser ranging method has the advantages of high measurement precision, relatively simple operation, relatively large influence by the environment, relatively high cost and very inconvenient later maintenance, so the laser ranging method is generally widely applied in the military field. The microwave radar ranging technology is used, the cost of a circuit part is high, the civil market is hardly developed at present, and the microwave radar ranging technology is only used for military and some industrial developments. The infrared distance measurement has the advantages of low cost, easy manufacture and safety, and the defects of low precision and poor directivity. Ultrasonic ranging, which is a non-contact measurement technique, can be transmitted in various transmission modes such as transverse waves, longitudinal waves, surface waves, and sheet waves in a gas, a liquid, a solid, or a mixture thereof, and can also be transmitted in a living body and a metal, which cannot be projected by other light. In the mining industry field, the borehole operation environment is changeable, and there are poison gas, smog, dust concentration height in many drifts, and light is dark, partial pit shaft ponding is many, and the operation security is poor, and other range finding modes such as laser range finding have certain limitation, and ultrasonic ranging has certain adaptability to these adverse circumstances, and anti interference performance in the pit is good, and test equipment stability is strong.

Ultrasonic ranging is a method of calculating a distance using a time difference when an ultrasonic wave propagates between an ultrasonic wave emitting device and a receiver. The main methods include a sound wave amplitude detection method, a phase detection method and a transit time detection method. The phase detection method is to judge the distance by measuring the phase difference between the return wave and the transmitted wave; the sound wave amplitude detection method is to judge the distance by looking at the amplitude of the echo; the transit time detection method is to judge the distance by the return time delay of the echo; the phase detection method has high precision, but the measurement range is smaller, the method is more commonly used in the precision fields of ultrasonic detection and the like, the acoustic amplitude detection method is greatly influenced by a reflecting medium, and the current main distance measurement method is a transit method. The fundamental principle of the transit time method is that an ultrasonic transducer emits ultrasonic waves under pulse excitation, the ultrasonic waves are reflected after meeting a measured object, and reflected signals are received by the ultrasonic transducer. Under the condition of known sound velocity, the distance is calculated by using the time difference between the emission and the reception, and the calculation formula is as follows: d-1/2 (c t); where D is the distance of the object under test, c is the propagation velocity of the ultrasonic wave under the test conditions, and t is the difference between transmission and reception, also known as the transit time.

The common portable ultrasonic distance measuring instrument has strong adaptability to underground distance measurement by utilizing ultrasonic waves. Because the traditional ultrasonic distance measuring instrument is not provided with a telescopic device, the safety problem exists in the measurement of the geometric dimension of some underground dangerous goafs; the traditional ultrasonic distance measuring instrument is not provided with a searchlighting device, is based on a distance measuring mode under the conventional common condition, does not consider the underground dark operation condition, and has deviation in the geometric shape distance measurement of a test object; the traditional ultrasonic distance measuring instrument is not provided with an automatic rotation control device, and the direction of distance measurement needs to be pointed manually; the traditional ultrasonic range finder is not provided with a vision module, the information of the surrounding environment is judged mainly by human eyes, the range of the visual range of the human eyes is limited due to poor light rays underground, and the information of the surrounding environment can be better captured by matching with a lighting device and a high-visual-range camera; the traditional ultrasonic distance measuring instrument is more limited in the mining field.
