Introduction:
In our project we are going to present modern era oil dispensing system for industries which is meant to be operated with touch screen interfacing. Operators of the dispensing systems should be trained perfectly so that they hold the controls until the required amount of oil is dispensed instead of this hard core mechanism we are designing with a touch screen based dispensing system which is going to dispense the particular to the required amount and is turned off immediately, the major advantage here is there is no need for any mandatory person to take care about the system. A password is assigned to this dispensing system so that unknown person cannot operate.
Touch screens provide fast access to any and all types of digital media, with no text-bound interface getting in the way. Faster input can mean better service. Using a touch interface can effectively increase operator accuracy, reduce training time, and improve overall operational efficiencies, thus keeping costs down, a properly designed touch interface can improve each operator’s accuracy. Touch screens are practical in automation, which has become even simpler with touch screen technology. Owners familiar with the icon system appreciate touch screens that make automation systems user friendly.
The system is designed with a Micro Controller, which is the heart of the device. It is interfaced with a touch screen based Graphical LCD and a dispensing motor. The user enters the password from the touch screen sensor, which is input to the device. The controller reads this input and control starts operating the dispensing motors until the required amount of oil is dispensed. The input from sensor is also displayed on the Graphical LCD for the acknowledgement of the user.
The major features of this project are:
- Touch screen based user interface.
- Accuracy in the amount of liquid dispensed.
- User friendly.
The project provides learning’s on the fallowing advancements:
