2.2 BLOCK DIAGRAM EXPLANATION: The project “GSM BASED VEHICLE THEFT CONTROL SYSTEM” deals with the design & development of a theft control system for automobiles which is being used to prevent / control the theft of a vehicle. The developed system makes use of an embedded system based on GSM technology. An interfacing mobile is also connected to the microcontroller, which is in turn, connected to the engine. Once, the vehicle is being stolen, the information is being used by the vehicle owner for further processing. The information is passed onto the central processing insurance system, where by sitting at a remote place, a particular number is dialed by them to the interfacing mobile that is with the hardware kit which is installed in the vehicle. By reading the signals received by the mobile, one can control the ignition of the engine; say to lock it or to stop the engine immediately. Again it will come to the normal condition only after entering a secured password. The owner of the vehicle & the centre processing system will know this secured password. We can modify this concept such that the vehicle owner also can lock the vehicle from his mobile phone. The main concept in this design is introducing the mobile communications into the embedded system. With the help of SIM tracking knows the location of vehicle and informs to the local police or stops it from further movement.
GSM BASED DIGITAL NOTICE BOARD
The user sends a SMS containing the data to be rolled.
PC receives the SMS and send it to both the slaves via RS232 -RS485 converter section. Both the slaves receive the frame. Then they match the slave ID in the frame to their own ID’s. If ID match occurs then that particular slave rolls the data on it’s alphanumeric display. GSM BASED DIGITAL NOTICE BOARD
