Design And Implementation Of Field Operation Information System Based On Beidou Technology

Field operations refer to various activities that need to be carried out in the wild environment,including geological exploration,geographic mapping,forestry patrols,power maintenance,field rescue,evasion and hunting,force training,and outdoor adventures.The operating environment of fieldworkers is generally rather harsh,and they are often located in areas where people are rarely visited and have poor cell phone coverage.Even fieldworkers' position information and work information are difficult to obtain in time.Therefore,work efficiency and personal safety are caused in field operations.In view of the practical problems and difficulties existing in field operations,this paper proposes an overall solution based on Beidou's short message technology to achieve position positioning and information management for field workers.Including the application of the Beidou terminal equipment and transceivers,the design of the monitoring center management platform,the establishment of the Beidou terminal and the monitoring center's information transmission channel,and so on.In the application of Beidou terminal equipment,it is connected with mobile phones,pads and other devices through Bluetooth communication,and the mobile phone APP software is used to realize the positioning of working personnel and short message communication functions;in the design of information transmission channels of the receiving and sending devices,Beidou terminal equipment is used of the convenience of interacting with mobile device information makes a mobile phone a short messaging device for sending and receiving short messages.The first is two-way communication with short messages of Beidou terminal equipment,and the other is through the Android debug bridge(ADB)to establish information transmission channels.Interact with the information of the monitoring center;after receiving the information sent by the Beidou terminal equipment,the management platform of the monitoring center completes the identification and conversion of information and stores it in the database,and displays the positioning information of the operator by calling the Baidu map API.Motion trajectory information and other work information to further real-time scheduling and management of field workers.After testing,the fieldwork information system designed in this project can realize the transmission of positioning information and short message information without the public network signal.It can display the movement trajectory of field workers in real time and can meet the basic needs.of communication and management in field operations.
