Design And Implementation Of Field Check System Based On Business Customization

With the upgrading of the application of high-resolution remote sensing images,the natural resource survey has changed from the traditional field survey to the work mode of indoor image interpretation with field data verification as a supplement.Based on the analysis of the functions and development modes of the existing field verification system,this paper puts forward a development method of field data verification system based on business customization,which greatly improves the reusability of software functions and significantly shortens the development cycle of software.The research contents of this paper include:1.For the problem that the field verification system oriented to the development of a single business cannot meet the needs of business expansion.In this paper,a development strategy combining field check interface customization and mobile terminal function development based on the existing business database is proposed,and the overall framework of field check system is constructed.The rapid construction of field check software is realized through XML file transfer and parsing.2.Through the construction of rule base,control base and style base,combined with the expansion of business database,the precise definition of check field,check rule,used control form and interface display style is realized,which provides basic components for the rapid development of field check software.3.GPS positioning and navigation,length,Angle,direction and area measurement,text and audio recording,photo and video shooting,new verification points and verification logs and other functions have been realized on the mobile end,and the construction of field verification software based on business expansion has been realized.4.13 kinds of wild fall into five categories based on the coal production capacity to check data and mine 2 kinds of 12 kinds of field verification that restore the data as an example,through the way of business,build the two types of business field verification of the software,proved the practicability and effectiveness of this development method,realizes the different instruments and equipment of the screen at the same time adaptive.This paper takes business customization as the breakthrough point,customizes the mode of field inspection interface according to business requirements,and carries on the adaptive design of screen resolution for different devices.The development of field check system based on business customization has been completed,and the purpose of expanding field check software business has been achieved.
