PROJECT DESCRIPTION

The project is designed to switch industrial loads using a user programmable logic control device for sequential operation with Raspberry Pi board. This operation is generally used for repetitive nature of work.

Programmable logic controllers used in industrial applications are very expensive for simple operations like sequential switching of loads. In this project we demonstrate the working of this simple operation using a Raspberry Pi board. The development of this application requires the configuration of the program through input key-buttons. In industries, there are many tasks are carried out which requires some repeated operation in various orders and time intervals.

For example, certain loads need to be switched ON/OFF in specific time intervals. In order to achieve this, Raspberry Pi board is programmed in such a way that the loads a can be operated in three modes: Set mode, Auto mode and Manual mode. In set mode, through timers, the machinery works based on input time set by the user where as in auto mode it works on default time settings and finally in the manual mode it functions while respective key-buttons are pressed depending on the user’s need and flexibility. All the modes and status of loads are displayed on PC monitor or a TV.

Thus, tasks performed by costly PLCs can now be achieved using a Raspberry Pi board making the device cost effective. Further the project can be enhanced by interfacing it with a GSM modem where by sending an SMS to the control system we can select the mode and timing remotely.

Q & A
Q:  Which microcontroller is used in this project?
A:  Raspberry PI in-built Celeron processor is used and development board is also provided with this project
Q:  What is programmable sequential switching?
A:  This project is designed to switch on the loads sequentially upon programmable time intervals.
Q:  What are the modes available in this project?
A:  Automatic mode runs on time specified in program, with Manual mode one can manually switch on and off the load and with SET mode user can set the time for each load.
Q:  Can we place a direct load other than the lamp?
A:  Yes, we can place a load other than lamp, but up to 200W.
