Security is prime concern for every one. Nowadays all the automotives are equipped with auto cop systems. Even though, the thieves are breaking the barriers and steal the vehicles.
This project is the right solution for this problem. Using this project, one can control his vehicle’s car engine by means of an SMS. There are various electronic equipment available for remote operation of device control. However, the main disadvantage of these systems is that they can be operated only from short ranges and also less reliable. Thus, to overcome the above drawbacks, we are using one of the wireless communication technique i.e., GSM (Global System for Mobile communications) is a digital cellular communications system which has rapidly gained acceptance and market share worldwide.
8051 is the heart of the project. A GSM modem is interfaced to microcontroller. This modem receives the messages from control mobile and sends as input to MCU. The MCU verify for authentication of the number and, if the number is authorised, engine control will be taken place, EEPROM is interfaced to this controller to save the engine position at every instant. This engine position information will not be deleted even in power failure conditions.
3X4 keypad is interfaced to change the mobile number at any time. 16X2 LCD is interfaced to display user-required information. In this project TRAIC is used as load controller (as a switch), MOC3021 used as a Triac driver.
GSM network operators have roaming facilities, user can often continue to use there mobile phones when they travel to other countries etc….
This project uses regulated 5v, 750mA power supply. 7805 and 7812 three terminal voltage regulators are used for voltage regulation.
Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12v step down transformer.
Advantages:
Vehicle can be controlled from any where
Mobile number can be changed at any time
Engine status will not be lost in power failure condition
Scopes for Advancements:
GPS modem also can be interfaced to this unit to trace and locate the geographical information of vehicle place
Applications:
Automotives Security
