摘要:
针对传统煤矿顶底板测距手段存在无法实时监测、检测精度低、实用性差、通信易断线等问题，创新性设计了一种基于LoRa无线通信技术的顶底板测距传感器，以集成相位法测距原理的激光测距模块作为距离测量核心模块，显著提高了顶底板距离测量的检测精度和实时性。从电路设计、逻辑控制机制2方面详细介绍了电压转换、5位数码管显示、光控接收、激光测距模块接口、声光报警、LoRa模块接口6部分电路设计方案，以及传感器的软件执行逻辑流程。现场试验结果表明，该传感器检测精度高、煤矿顶底板测距实用性强、安装方便，满足设计需求。
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,the practicability is poor and communication is easy to break,a new type of top and bottom plate ranging sensor is designed based on Lora wireless communication technology,which uses the laser ranging module based on 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 circuit design and logic control mechanism,including voltage conversion,five-digit tube display,optical control and reception,laser ranging module interface,sound-light alarm,LoRa module interface,and the software execution logic flow of the rangefinder are presented.The field test results show that the sensor has high detection accuracy,high practicability in distance measurement of coal mine roof and floor,convenient installation and meets the design requirements.
