| With the vigorous development of the mobile communication industry and the continuous innovation of modern information technology,the era of big data has come to people.In addition,with the deep integration with the positioning technology based on 4G and 5g,the effective application of location-based service positioning technology has not only brought profound changes to people’s production and life,rapidly promoted the continuous progress of society,but also improved the work efficiency of the government,enterprises,institutions and troops have provided huge productivity.For example,some government departments have applied this technology to social governance and launched a series of integrated software with functions such as online social security payment,online reservation and registration,police communication,one click rescue and so on.These measures not only solve the actual demands of the people,but also continuously improve social efficiency.This paper is based on some research results in the current industry field,and also from the reality of personal work,because up to now,there is no software with tracking and positioning function in the discipline inspection and supervision system,but there are many applications of positioning function in the work,such as studying and judging problem clues,tracking respondents,etc,Therefore,in order to meet the security and confidentiality requirements of their work,this paper intends to develop a location-based object tracking system by integrating the characteristics of various positioning technologies,which should not only meet the positioning accuracy and response,but also ensure the safe and convenient use.In the object tracking system based on LBS,considering the characteristics of geographic location,bank flow and a large number of data application and calculation,we determined the relevant development platform,database,positioning technology and data mining technology as the basis.On the one hand,in terms of positioning and tracking,first we need to collect station information data,including RSSI,LAC,CID,etc.,and then reduce the positioning error to a greater extent through the least square positioning algorithm based on the data mean,so as to obtain the preliminary positioning data,and then through the candidate location matching algorithm based on geographic data,map data The preliminary positioning data is preprocessed to obtain the set of candidate location points located by the base station.Then,through the optimal path algorithm based on probability sequence group,the matching degree between the calculated location and the actual geographical configuration is greatly improved.On the other hand,in order to better mine the track data function of the target object,we input the bank flow data and screen the suspicious data,and grasp the relationship between the track and the suspicious behavior in combination with the user’s track in a certain period of time,so as to provide help for the breakthrough investigation of the case.At the same time,taking into account the requirements of work safety and confidentiality,it ensures that each function can be checked by setting different permissions of the account and using workflow technology.Finally,we tested the integrity of the system function.Finally,we can clearly obtain the map information of the user’s track,get the track of the target object and the suspicious water flow.At the same time,we also compared the system memory occupancy under different conditions.Later,we will further improve and update the system function in combination with the actual needs. |
