The Design And Implementation Of Field Data Acquisition System

With the continuous expansion and development of the nature reserves,a large amount of work will be processed in the management process of recording and managing the related data of nature reserves.It is difficult to meet the demand with the traditional way that is post processed by the information collector.Android smart phones are the mainstream of the current mobile devices.There are many advantages for it.They are convenient to carry,and the configuration hardware of them are better and better.At the same time,the ability of collection information is becoming more and more powerful.Based on these characteristics,they can become an important tool which can effectively save manpower and material resources to improve work efficiency in the field work.The system which combines technology with Android provides convenience for the data collection work in the nature reserves,and it has a very important practical significance.In this paper,based on data collection and management of the nature reserve present situation,we design and implement the field data acquisition system.The information collector can carry on the information collection which includes user management,multimedia data entry,positioning and direction instructions,uploading information and settings through the mobile client.And then they can upload the collected data to the server through the network.Finally,information processor can view and manage the data at the remote server.The main functions include user management,task management,and collection information management and so on.In this paper,the Android and GPS positioning,Baidu maps are combined to achieve the function of navigation in the data collection of the nature reserves.In addition,because of the particularity of the working area,it may appear that the collection point can't be displayed.Based on the specific latitude and longitude of the acquisition point,the distance and the direction angle between the current position and the target position of the information collector are calculated,and the results are displayed in the client interface.According to the given information,the information collector finds the collection point successfully,and it makes the field data acquisition work much more effectively.
