The Design And Implementation Of The Multi-mode Base Station Information Collection System

With the development of science and technology,the call records have been become one of the ways to solve crimes.In order to help the police narrow the scope of the suspects,speed up the efficiency of the police work,and improve the social security.This paper designed a Multi-mode base station information collection system.It can make the police work convenient.The police can find the nearby service base station information through the main community base station information,than pull database from this base station,finally find out mobile users suspected who connected into the close-by base station recently.Embedded structure is chose as the hardware structure of Multi-mode base station information.This paper design hardware circuit based on the chip of S3C6410 which is a 16/32-bit RISC MCU of SAMSUNG.Hardware includes USB hub circuit,serial debugging circuit,and isolated power circuit,etc.The paper design schematic diagram of circuit and two-layer PCB board in the software Altium Designer.This system mainly has five major functions,which are divided into main and auxiliary functions.Main function is divided into information acquisition function of base station information,location information and map display function.Auxiliary function is divided into database storage function and the function of using the wireless network to transmit data to server.Community information acquisition function mainly contains the Telecom,Unicom,Mobile three modules and 2G,3G and 4G three system of information collection.Acquisition mode can be divided into fixed point acquisition mode and continuous acquisition mode.Location information acquisition function mainly contains the acquisition of latitude and longitude,address and time of the acquisition,location information acquisition can help the collectors to analyze and familiar with the geographical situation.Map location functions can let the collection such as the latitude and longitude and location displayed on the Amap,also the function can display collectors’moving-route and analyze the location information.Database storage function mainly contains the action to Community information,latitude and longitude information,address information,time acquisition.The function uses the information for storage and display.The users can use the database,timely analysis and screened of the collected information,to speed up the efficiency of the public security personnel working.Network upload function to implement the acquisition of the information uploaded to the PC through the network server,collectors can process the information through the server database,the users can compare and analysis the information.The experimental results show that this paper implements the above functions and the system work stably.
