Vehicle monitoring system using a GPRS tracker device and Google Maps

  1. 1. Vehicle monitoring system using a GPRS tracker device and Google Maps Gafițescu Daniel & Prof. Dr. Ing. Botez Claudia
  2. 2. How does it function?
  3. 3. Used tehnologies <ul><li>Php5 </li></ul><ul><li>Mysql (but can be used any other RDBMS because it uses PDO , a database abstraction layer) </li></ul><ul><li>Javascript – framework ExtJs </li></ul><ul><li>Ajax - Asynchronous JavaScript and XML </li></ul><ul><li>JSON - JavaScript Object Notation </li></ul><ul><li>XML </li></ul><ul><li>Google Maps – free web mapping service application and technology provided by Google </li></ul><ul><li>Google Geocoding – free web position system based on the address </li></ul><ul><li>All the technologies are open - source </li></ul>The cost is minimal and it is represented by the cost of the gprs devices installed on the cars and server with Linux on it and having and real IP
  4. 4. Application schema Application is design using the Model-Viewer-Controller arhitectural pattern
  5. 5. Application functional scheme
  6. 6. Country component Manage countries ; the dispatcher can create , edit and delete countries Station component Manage stations ; the dispatcher can add , edit and delete stations.When you add a station the coordinates are obtained using geocoding based on the address that dispatcher added geocoding în funcție de adresa introdusă de dispecer Journey component The dispatcher can create a journey based on the stations added in the station component At the end , the dispatcher can see on Google Maps the optimal path between the stations
  7. 7. Car component The dispatcher can add , edit and delete cars from the fleet Here the dispatcher enter here the phone number assign to the SIM card that is inserted in the gprs tracker. Map component In this component the dispatcher can see on Google Maps the position of the cars on each journey Dispatcher component In this component are managed the dispatchers They can be added, delete or edit.
  8. 8. Eraytech AVTS-1500 – grps tracker <ul><li>The device </li></ul><ul><li>- plug in the electric system of the car. </li></ul><ul><li>IN/OUT interface – can be equipped with Standard Barcode (for taxi drivers, when they give the customer the bill , all the data is send to server), RFID (Radio-frequency identification) . </li></ul><ul><li>USB –B type – and can be connected to a PDA or notebook for navigation assistance </li></ul><ul><li>(GPS navigation) </li></ul><ul><li>- antenna GSM/GPRS si GPS for communication </li></ul><ul><li>SiRF Star III GPS module - 2DRMS accuracy is 5 met ers , and can perform on temperatures between -40 °C and + 85°C </li></ul>
  9. 9. Geocoding <ul><li>This is the proccess of determine the latitude and longitude </li></ul><ul><li>of a certain address or location </li></ul><ul><li>Google offer for free to developers the geocoding system as a </li></ul><ul><li>web service </li></ul><ul><li>Accuracy is very low in the Eastern Europe </li></ul><ul><li>(Romania has a city accuracy level , but this will improve in </li></ul><ul><li>future) </li></ul>Geocoding example Iasi , Romania Latitude =47.156951 , Longitude 27.589853 Google geocoding Informatic system
  10. 10. Similar systems Swiss Trains ( http://www.swisstrains.ch) - uses Google Map to simulate the position of trains in Swiss in real time drawing the trajectory every 30 seconds <ul><li>gives the users information regarding the direction of the train </li></ul><ul><li>and waiting times </li></ul>
