PROJECT DESCRIPTION

The main concept of this project is to control the industrial loads sequentially in three modes: automatic, manual and pre-set modesby using relays with programmed Raspberry Pi development board.

In industries, many tasks require some repeated operation with specified time intervals, which is possible by Programmable logic controllers, but these are expensive for simple operations like sequential switching of loads. This project is proposed to switch the electrical loads sequentially by programmed instructions.

The proposed system uses a Raspberry Pi board and a rectified power supply. Monitor and keyboard is connected to the Raspberry Pi board so that a user can set timingsof loads and can modify the program. In this system, the relays are controlled by the relay-driver IC, which is connected to the Raspberry Pi board. The lamps are connected to the relay contacts for indication purpose.

As mentioned above,the set mode is operated by the timers based on the input time set by the user, auto-mode works on default time settings as per the programand the manual modeis operated by the user with respective key-buttons that are required to be pressed on the keyboard. All the modes of load status are displayed on a TV or PC monitor.

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.
