手持式工程测距仪设计

北京理工大学珠海学院2020届本科生毕业设计The Design of a hand-held rangefinderAbstractWith the rapid development of automated working equipment in recent years,theimplementation of rapid distance detection has also continued to develop and improve.At present,the main research direction of fast distance detection is non-contactdistance measurement technology.Non-contact distance measurement research haspenetrated into civil,industrial,military and other fields,and has formed a variety ofdistance measurement methods using infrared,ultrasonic,laser and other technologiesas carriers.For example,with the increase in the demand for civilian cars,the numberof smart cars driving on the road is increasing day by day.In the field of engineeringdetection,the use of laser ranging technology can achieve a rangefinder solution withlow error,high anti-interference,multiple use scenarios,and portability.Comparedwith other measurement technologies,laser ranging has the characteristics of highranging accuracy,good directivity,strong environmental anti-jamming capability,easy portability and fast measurement speed.This design is a hand-held rangefinder.It develops a laser rangefinder that is easy to operate,long in use,quickly outputmeasurement results,and is light and portable.It meets the simple measurement anduse of people's daily life and improves the simplicity of measurement.Withmeasuring speed.After analyzing the main non-contact distance measurementtechnologies,the system design uses the TF-Luna laser distance measurement moduledeveloped by BENEWAKE to design a portable device that includes a laser distancemeasurement module and an information display module with the STM32 maincontrol as the core.Low-energy handheld engineering range finder.Keywords:Ranging;laser;time of flight;STM32;TF-Luna
