Programmable Sequential Load Operation Controlled By Android Application
The project is designed to switch industrial loads by making use of android app through logic control device programmed by user. The system is made to be used in repetitive nature works. This remote controlling task is achieved through the use of any android based device (phone/tablet) running on an android OS. Using programmable logical in order to achieve sequential switching of loads proves a very costly operation. Here we propose a simple and cost effective alternative to the issue by making use of 8051 microcontrollers. The controlling part is provided on an android application.
Various tasks and in today’s industries work on repeated operations in varied orders and intervals. Consider an example there a motor needs to run after every 3 seconds. So for this purpose we program the microcontroller to work in three different options: Set option, Manual option and Auto option. When the set option is selected, the system works according to time intervals entered by user. In auto option the system now works as per default time settings while in the manual option it operated on pressing the selective switches as and when needed by the user. All modes and status are displayed on an LCD display. Our project thus provides very cost effective system to automate industry loads as an alternative to high cost PLC’s used.
