Design And Implementation Of Fiel Investigation System For Mobile Intelligent Terminal

Field Work refers to the process of collecting original materials,information and data in the Field investigation,which is widely used in humanities,social sciences,environment,ecology and other natural sciences.The traditional techniques and methods used in the current survey are relatively simple,mainly manual recording.For the collection of information and data,digital cameras,DV machines,recording pens,GPS locators and other devices are mainly used.Not only the equipment is various and the portable use is inconvenient,moreover needs the massive manpower and the material resources investment.In the post-processing process,it is necessary to classify,analyze and store the information resources obtained by a variety of acquisition equipment and channels,which is heavy and error-prone.In view of the shortcomings of the traditional field investigation techniques mentioned above,this study is put forward.The field work system based on the intelligent terminal realized in this study integrates the functions of photography,recording,video recording,positioning and basic data entry through the mobile terminal(such as smart phone),aiming to improve the efficiency of field work.The main functions include:spatial positioning,photos,audio,video,basic information survey and the acquisition of survey information,which greatly reduces the labor cost and the number of equipment.Meanwhile,through the mobile data network,the collected information is transmitted to the PC(means server)background management system in real time,which effectively improves the efficiency of field investigation and reduces the probability of errors in repetitive labor and manual data entry.And by the PC terminal system to achieve data transmission and survey data management and use.The system adopts the B/S development mode,based on the phalcon framework,and adopts the MVC design pattern.The development of mobile intelligent terminal and PC management system is mainly implemented by web scripting language HTML,CSS,Javascript and PHP,At the same time,the MySQL database is used to manage related data,and the network link is completed by using the integrated environment software XAMPP and Apache server software.Through the process of requirement analysis,system design,programming realization and system test,the system is developed.This study gives full play to the functions and characteristics of smart phones.On the basis of meeting the basic needs of information collection in field work,combined with the management and use of data information by background PC,it provides efficient and convenient information acquisition technology and guarantee for field workers and effectively promotes the development of technology in this field.
