Vigilance Control Device (VCD) monitors alertness of the driver on continuous basis by
checking his actions while running a train.VCD monitors various signal inputs from loco
through which driver’s alertness can be monitored. In the absence of loco signal inputs,
the driver has to press Foot switch within the specified time intervals when the train is
in movement. VCD system monitors the various signals (Detailed in the later sections of
the document) in predefined time.
The pre defined time is classified into three types of cycles and these cycles are executed in a specified time frame. By pressing the any input signal within the specified time period, the cycle execution process will get reset. If the driver doesn’t activate any input signal, then the VCD considers the loco as an unmanned loco and hence a penalty brake is applied to stop the locomotive for the safety of the passengers and also for the safety of the Locomotive.
Electronic Product with in house designed power supply & dsp boards. .
Used in Tap Changer Electric Locomotives.
More than 2000 units in field service.
VCD is used to monitor the alertness of the loco pilot during the operation of the locomotive , by sensing various functions performed by the LOCO Pilot like Horn, MP, A9 ,SA9 ,Sander etc.
If these signals are not received by the VCD during a specified time interval it will apply the penalty break using IP valve for the safety of the passengers and locomotives.
VCD will store around 1 lakh events at the give point of time which can be retrieved through front end software.
