INDUSTRIAL AUTOMATION THROUGH SMS

This project is aimed at developing control of equipments connected to a PC
through SMS. Usually switch control is used to control the electrical equipments. It is
a manual task and a person has to go to the distant place in order to control the
equipment when switch control is located far from easy reach. This inconvenience
can be minimized by using wireless communication developed in our project. This
system has been developed using a PC & a mobile. The former acts as a command
initiator and the latter acts as a command receiver. Both are capable of
communicating serially. The PC is equipped with buffers to the relays through
parallel port. The operation to be performed is sent by mobile as SMS to PC. The PC
on receiving the SMS, controls the equipments connected to it appropriately.
Software has been developed in C to TX/RX serial data. Serial port software
routines are used to configure and communicate. ON/OFF controls of relays are done
by parallel port software routines. Specific software commands are used to control
each equipment
