1. Sensor Vigilance Warning 1 INTRODUCTION In railways most of the accidents have been caused due to failure of railway staff Under optimum field conditions and with the best of intentions a human being is likely to commit a mistake from time to time This is the reason why operating conditions include so many redundancies in safety process and operating rules involve number of checks and balances The paper provides a method to prevent train accidents by alerting the loco pilot cyclically at regular time intervals The Vigilance Control Device VCD is an ARM7 Micro Controller based Device which will automatically apply the penalty breaks in case the driver is in unalert or dead or fast sleep This system was introduced to prevent train accidents even if the driver died at his controls hence the name Unless a certain amount of pressure is maintained on the lever brakes get automatically activated and the train stops In this case the facility to inform the action of the loco pilot and the position of the train to Vigilance Control Officer to take any responsible action 2 EXISTING SYSTEM In existing system is the AT89S52 micro controller based driver safety system which detects inputs from loco pilot It can give continuous warnings to driver alertness give emergency braking system and the position of the train to higher authorities to take action In this system to ensure safety to passengers the new automatic braking system is pr2.
