<p>Road Runners mechanism obtains its power supply from vehicle main battery supply by means of Automatic ON/OFF GSM module which in turn connected with transformer based DC to DC converter component, that specified DC to DC converter converts the high amps of power supply to reduced required Amps of power supply needed for Road Runners mechanism for its functioning by means of an Automated GSM based Switch, the GSM based component consists of ATMEL 89S52 microcontroller with a GSM component and DPDT relay, If the GSM based command SMS 'ON' reaches the GSM component ,then the ATMEL controller activates the Relay associated within it and passes the desired amount of power flowing from the Dc to Dc converter to Road Runners mechanism Gadget. When the GSM based command SMS 'ON' reaches the GSM component of ATMEL controller board so that ATMEL controller activates the DPDT relay simultaneously at the same time, the mobile user will be get Acknowledged with an SMS as 'SUCCESSFULLY ON' as response through which the 'ON' SMS had been sent. If the GSM based command SMS 'OFF' reaches the GSM component then the ATMEL controller deactivates the relay associated within it and cuts the flow of power from the DC to DC converter to the Road Runners mechanism. The DPDT relay consists of one set of the common pins (CO) and another set of the normally open (NO) pins and normally closed pins (NC). Initially the normally closed pin is in inactive state before message has received. When the ON SMS had been received by the ATMEL controller through GSM board connected within it, the common pins were triggered and so that wires connected to the common pins will get contact to the normally closed pin of the DPDT relay and power supply will passes from the cars main battery to the Road Runners mechanism kit and similarly the vice versa for the OFF SMS had been delivered to the ATMEL controller through GSM board ,this SMS sending feature for Automatic ON/OFF the Road Runners mechanism can be facilitated through Road Runners App, as soon as SMS commands reaches the proposed GSM component, so that the ATMEL controller board requires a continuous flow of current from the vehicles main battery to keep the GSM based ON/OFF mechanism alive.</p> |
