DCCMY VIEWPOINT

Flexible working hours

Feels good

Flat Hierarchy

Easy to Communicate

Friendly and co-operative environment

Too much helpful for fresher’s and interns

Perfect school for interns

Enriched study materials

Introduction I completed my required 8

weeks of internship at DCC Tech.

I worked primarily on the B- Vehicle Simulator which is the currently on going project at Mai Kolachi DCC.

I worked currently on the 12 B- Vehicles which were made from scratch and are to be dispatched in a few days.

Other Miscellaneous projects were BRT lines ticketing system which I worked for a couple of days.

General Block Diagram

Bulk HeadBulk head is the

main part of the B-Vehicle .

It controls the whole electronics of the B- Vehicle through the cards mounted on it.

Mechanical Assemblies

Dashboard Panels, Indicator Knobs, ignition, Steering Wheel, Clutch, Accelerator, Brakes, Gears ( 4 Wheeler and normal), handbrakes.

Instructor ConsoleInstructor Console

is used for surveillance and operating all the Vehicles from a single point.

It has both software installed in it one to run the B-Vehicles and the other is the instructor console own software.

Production line of B-Vehicle

Procedure to make a B-Vehicle

InstallationsThe desktop PC’s used

have high memory video cards and RAM to support a graphical user for the B-Vehicles.

40 inch LED used to get a clear picture of the whole simulation.

Two software most importantly used for B-Vehicles

Smart Card CheckerThe Simulation trainer

software that contains all the code, GUI and background file to process it.

Troubleshooting

TroubleshootingSmart Card Checker First base to start Trouble

Shooting. Check all the input and

output bits one by one from the Port Assignment list.

Output ports reads the data from the smart card checker.

For input ports data has to been written onto the smart card checker.

TroubleshootingRouting If the smart card checker finds a fault then check for the

whole routing connections as shown in the first diagram using the diode test.

Start from the biggest routing (Route C to Route A) and if a fault is found then go for further route combinations to find an actual fault.

TroubleshootingAssembly Connection If the routing connections are ok then dissemble the

instrument you’re getting an error with and check for the internal wiring of the instrument again using a diode test.

The instrument also incubates a special pcb which are connections for different functions of the instrument.

Put one pin to ground and the other to the switch pin if the pin is working properly then the buzzer sound should be heard when switched on.

TroubleshootingCard FaultsIf the assembly connections are also verified then

check for the temperature of the IC or any other electronic component.

Code not burned into the microcontroller.Check for any power supply faults.Check for cabling faults.Check for power connections to the card. Check the power supply.Replace the card.

RecommendationsElectronicsUse a full fledged motherboard or a complex PCB

design which have less wiring to do.A challenging work for engineers to do. It can be long lasting.

RecommendationsSoftware Improvements in graphics.Speech and text training to the drivers (like a GPS

system).General improvements in code such as the indicator

system, steering wheel.

RecommendationsMechanicalDiameter of the steering wheel is too small as compared

to original B-vehicles.The structure of the simulator does not replicate with the

original jeeps of the buyers, which are mostly army men.
