Design And Implementation Of RTK Handbook Software Based On Android Mobile Phone

As a carrier for RTK measurement and production,the RTK Handbook has far-reaching significance for the rapid development of RTK technology.At present,the RTK handbook system at home and abroad is mainly based on the proprietary design and development of Windows CE system and Android system,ZhongHaida's Hi-Survey software is based on Android's proprietary devices.When it is installed in the process of using a universal Android mobile phone,it is found that the stability of the software during the operation is poor,and problems such as stabling and flashback occur.In addition,RTK book software is generally sold together with proprietary equipment produced by manufacturers,which increases the user's purchase cost.In order to better adapt to the trend of the development of network RTK technology and improve the versatility of handbook software,I decided to re-learn from the bottom,design a handbook software based on Android mobile phone specifically for network RTK technology and named it ZK-RTK hand book software.The main content of this article is the following three aspects.First of all,Analyze the RTK principle and introduce the related technology of Android development.Analyze the mathematics model used for coordinate conversion,choose the calculation formula suitable for computer.Secondly,by analyzing the functional requirements of handbook software in detail,the five major functional modules of handbook software are constructed.According to the demand analysis of the handbook software,the overall framework of the software is designed.Based on the principle of Bluetooth communication,a wireless communication protocol was designed to realize the Bluetooth wireless communication function.According to the mathematical model of coordinate transformation,the coordinate conversion class was designed and the coordinate conversion function was implemented.In order to better understand the current satellite conditions and RTK positioning status,a floating window module was designed.Furthermore,In order to improve the efficiency of field measurement management,the design and implementation of the project management module.by analyzing the characteristics of the receiver data format,the data analysis module is designed to implement the data analysis function.Combined with measurement requirements,a measurement module was designed to achieve basic measurement functions such as static measurement,measurement of broken parts,point lofting,and line lofting.Finally,The ZC-RTK software was systematically tested to improve the deficiencies in software testing.
