Introduction

Fig1:cable car

• A cable car is any of a variety of transportation systems relying on cables to pull vehicles along or lower them at a steady rate.

Contd……

• The cable car vehicles are motor-less and engine-less pulled by cable that is rotated by motor off-board.

• The project aims is to demonstrate the automation of a cable car system using Programming Logic Controller.

• The system consists of automatic opening and closing of cable car doors by use of IR sensors.

Contd…

• The system also consists of a passenger counting system for single trip and also the total passenger count based on an IR sensor .

• The PLC is used to control the Motors for door opening and closing as well as movement and stoppage of cable car system.

COMPARISION BETWEEN CABLE TRANSPORT AND FUEL TRANSPORT

CABLE CAR

• Pollution free.• Environment friendly.• Accidents rare.• Large carrying capacity.• High efficiency

FUEL CAR

• Pollution present.• Not friendly.• Accidents prone.• Low carrying capacity.

• Low efficiency

Technical Defaults Limitations: • Mechanical opening and closing of doors of

cabin.• Lack of evenly distribution of load in the

cabins.• Overloading in cabins as there is no counting

of boarders.• Time independent opening and closing of

doors of cabin.

Circuit Components1. IR Sensors:

• IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-Red (IR) spectrum.

FUTURE SCOPE

• The cable system car system can be made fully automated and safe by including weight measurement in the cable car using load cells.

• Transistor an receiver can be used for communication between PLC and IR sensor.
