VietNamNet Bridge - An old mobile phone installed with remote-control supervision and anti-theft system can easily find the location of a vehicle.

 

“I once lost a bicycle which I bought with many years of savings. I then told myself I need to invent a system which can supervise the itinerary of vehicles after they are stolen and send information back to my mobile phone. If such a system exists, I will be able to find my assets,” said Vo Minh Nam, a student at the HCM City University of Technique Education.

Nam and his friends implemented a project on building the system to supervise and prevent vehicles from being stolen.

According to Nam and his friends, there are many different types of locks now available in the market advertised as able to prevent theft. 

However, thieves with advanced techniques can steal motorbikes with sophisticated tricks. 

“The system uses GPS (global positioning system), used widely in many different fields, from navigation to mapping and searching. Our product is equipped with a positioning module and installed with an app operating on Android which can supervise and regulate vehicles,” said Mai Trong Nhan, a member of the group.

An old mobile phone installed with remote-control supervision and anti-theft system can easily find the location of a vehicle.

Vo Minh Nam is not an information technology student, so he found it difficult to write a mobile app run on Android operating system. 

Nam had to search for information on the internet and read books for basic knowledge about software programming. 

Nam and his friends failed several times designing electric circuits because they did not have the right tool to weld chips to the circuit board. When chips had problems the entire electric circuit broke down.

“Sometimes we wanted to give up because we spent a lot of money on electric circuitry. But we later changed our mind,” said Nguyen Thi Huynh Nhu, a member of the group.

Finally, the remote-control supervision and theft-prevention system was created. 

It comprises two main parts. There is a positioning module attached to a motorbike which receives information from satellites to calculate co-ordinates, the module’s speed, and current time and then it displays information on screen. 

The positioning system on motorbikes is attached with a sim card to communicate with mobile phones through messages and calls to transmit information.

The second part is an app that receives information sent from the modules, processes the information and displays the positions of modules on Google map. The app will suggest the shortest way to reach the vehicles.
