Research On Intelligent Interaction And Push System Of School Bus Based On Multi-information Sources

The school bus is the primary means of transportation for primary and secondary school students to go to school and its number has increased in recent years,but safety accidents occur frequently.To ensure the safety of school bus and the establishment of intelligent interactive platform for school bus is imperative.At present,GPS positioning technology and the development of 4G network is mature,the application of electronic map is extensive,and the use of Android smart phone is increasing,which makes the intelligent interaction between mobile phone and school bus possible.According to the background and current situation of school bus regulation,the paper designs a kind of intelligent interaction and push system of school bus based on multi-information sources,realizes the interaction between the vehicle terminal,the server and the mobile client,and solve the worries of school,parents and school bus drivers technically.Firstly,the functional requirements of the system are analyzed and the key technologies such as imformation fusion,GPS,RFID,JNI and JPush are studied,and the overall scheme of intelligent interaction and push system of school bus is designed.Secondly,the algorithm of information fusion is studied,and the multi information acquisition of school bus' s location,student's travel record and driver's drinking status are realized.Third,the four modules of the school bus intelligent interactive platform-vehicle terminal system,server,mobile client and push system are designed and implemented.Vehicle terminal system collects location information of school bus through the GPS/ODO module,records student's travel situation through the RFID module,and detects the degree of drinking of the driver through an alcohol detection system based on fuzzy reasoning and multi-sensor fusion algorithm;server-side achieves the data storage and verification through the Tomcat server and MySQL database;JSON format based on the HTTP protocol is proposed to exchange data between Server-side and Android-side;the school bus real-time monitoring,navigation,track playback and other functions are achieved through the secondary development of Baidu map andcompleting the client application program;the school bus message push service is achieved through the client-integrated JPush SDK.Finally,the functions of real-time display of the school bus,student identification,driver's alcohol concentration detection,school bus map service,information push and other functions are tested.The results of the online test show that the application platform of intelligent school bus has realized the function of safety driving,recording ride status of students,school bus positioning,navigation,track playback,real-time remote monitoring and push service,which provides a safe and reliable solution for school bus supervision and has certain practical value of lower cost,easy to use,simple operation and can meet the actual needs of school,parents and school bus drivers.
