【 摘 要 】

Underground cable laying is an alternative for overhead cable laying of telecommunication and power transmission lines. It is becoming very popular in recent times because of some of its advantages over overhead cable laying. This type of cable laying is mostly practiced in developed countries because it is more expensive than overhead cable laying. Underground cable laying is more suitable when land is not available, and it also increases the aesthetics. This paper implements the automation on a manually operated cable pulling winch machine using programmable logic controller (PLC). Winch machines are useful in underground cable laying. The main aim of the project is to replace all the mechanical functions with electrical controls which are operated through a touch screen (HMI). The idea is that the machine should shift between parallel and series circuit automatically based on the pressure sensed instead of manually operating the solenoid valve. Traditional means of throttling the engine using lever and wire is replaced with a linear actuator. Sensors such as proximity, pressure and load sensor are used to provide the input to the system. The HMI used will display the speed, length and tension of the rope being winded. Ladder logic is used to program the PLC.
