Design Of Remote Anti-theft Control System For Electric Two-wheeled Vehicles

With the development of economy and the improvement of electric two-wheeled vehicle technology,more and more people use electric two-wheeled vehicle to travel.The use of electric two-wheeled vehicles makes people’s travel more convenient and fast,but it also brings some regulatory difficulties.In daily life,electric two-wheeled vehicle theft often happens,affecting social harmony.How to ensure the safety of electric two-wheeled vehicle and improve the performance of anti-theft is an important subject worth studying at present.From the angle of anti-theft and tracing,this paper analyzes the requirement of the anti-theft system of electric two-wheel vehicle,and designs a remote anti-theft control system of electric two-wheel vehicle based on STM32 main controller and Android mobile phone control APP.The STM32F103ZET6 main control chip used in the on-board part of the electric two-wheeled vehicle carries the Beidou positioning module,the lock-opening Discrimination Module,the information storage module,the language broadcast module,the LCD display module and the 4G DTU module,the hardware structure of the remote control system is established.The software is written through the Keil 5 software development platform to achieve the required control functions,and the APP is developed by using the Java language in the Android Studio Development Platform to achieve the remote anti-theft control functions.In order to identify the validity of the driver of electric two-wheeled vehicle,the function of unlocking and identifying is designed.Through the lock-picking discrimination module,it detects whether there is a lock-picking behavior,and then ensures the driver’s legitimacy by sending a lock-picking request to the owner’s mobile phone-side control APP and calling the owner’s authorization,to Stop the illegal unlocking and stealing of the electric two-wheeler.By setting an electronic fence at the on-board end of an electric two-wheeled vehicle,the main controller can directly process the Beidou positioning data to realize the judgment of whether it is out of range,thus achieving the goal of remote monitoring the position of the vehicle,it changes the disadvantage of the traditional setting of the electronic fence in the mobile APP,which results in the continuous data transfer between the mobile phone and the main controller and the waste of the traffic.By means of the voice broadcasting module on the car-side to play the alarm voice in case of theft,the passer-by is aroused to stop the theft,and the electric two-wheeled vehicle is stopped from being stolen in time.The main controller transmits the longitude and latitude data from the Beidou module to the APP,and then calls up the method of showing the location of the vehicle on the map of Baidu,which realizes the precise control of the position of the vehicle and solves the problem of finding the vehicle after being stolen.By means of reading the identity information embedded in the main controller of the vehicle,the problem of the ownership of stolen vehicles is solved,and the disputes caused by the identification of similar vehicles are solved.Finally,each function module and the whole system are tested,the test results show that the system can realize the functions of position data acquisition,data transmission,position monitoring,car stealing alarm,car owner identification,remote control and inquiring the position of electric two-wheeled vehicle in the mobile phone control APP,the long-distance anti-theft control function designed is feasible and has practical value.
