Research And Design Of Surveying And Mapping System For Portable Laser Rangefinder

With the rapid development of the Internet,the "Internet +" model is increasingly used in life and work.The Internet of Things is also a branch of the development.The combination of online and offline applications is also emerging in daily life.Laser ranging has also shifted from traditional ranging methods to more convenient measuring methods.This article combines the actual situation of portable laser rangefinder.After doing in-depth comparison analysis and research,a mapping system was designed based on the traditional portable laser rangefinder,making laser ranging more convenient.Through the investigation and in-depth study of the current situation of portable laser rangefinders,this paper determines the overall research and design scheme of the portable laser rangefinder's mapping system,including the hardware circuit of the laser rangefinder and the software design of the mapping system.The hardware system is mainly divided into laser transmitting circuit,laser receiving scheme and counting circuit.The mapping system is designed and implemented under the framework of Ionic + Cordova.This article introduces the hardware design circuit and software implementation of the portable laser rangefinder in detail.Data is transmitted through the Bluetooth low energy module(BLE)and the transmitted data is visually output,and the drawings are designed intuitively on the mobile interface.The overall operating process of this system is: first open the app on the mobile interface,and then use the portable laser rangefinder to measure data through the Bluetooth module for data transmission and visualize graphics based on the transmitted data.The drawing system includes the corresponding application Scenes and virtual items.Makes the laser ranging data output more convenient and visual.
