Design of Mining Laser Rangefinder Based on Phase Method
Abstract:Aiming at the problems of the traditional mine measuring instruments and methods about roof to floor convergence that can not be monitored in real time,the detection accuracy is low and the practicability is poor,an innovative laser rangefinder is designed,which uses the integrated phase ranging principle as the core module of distance measurement,and the detection accuracy and real-time performance of roof to floor convergence are greatly improved. Six parts of the circuit schematic scheme are presented in details from two aspects of device selection and logic control mechanism,including the step-down circuit,interface EMC circuit,five digital tube display circuit,remote control circuit,interface circuit of laser ranging module,communication circuit,and the software execution logic flow of the rangefinder are presented in details too. The basic performance and function of the rangefinder are tested in laboratory and field,the experimental results show that the rangefinder has the characteristics of high detection accuracy and strong practicability of coal mine roof to floor convergence,which meets the design requirements.
