Abstract:
This research displays the design of remote control system based on
Short Message Service (SMS) for displaying publicity on Liquid Crystal
Display (LCD’s). By sending messages in the form of SMS through mobile;
It is a wireless transmission system which has very less errors and
maintenance. The control center is supplied with Global System for Mobile
communications (GSM) for SMS transmission and reception.
The GSM receiver is connected to a microcontroller (AT mega 32) the
heart of the system,(is used to store the timings and messages to be displayed,
decodes the messages and accordingly sends commands). The microcontroller
issues orders to display advertisements as required by the message. It's
interfaced with LCD (40*2) display unit. Microcontroller coding will be done
using Embedded PASSCOM.
The control system consist of two separate units, control center and
control unit.
In the control center a PC can be used with an administrator for
monitoring the system so can operation indoors, the indoors electronic
devices are within the temperature and humidity limits for proper operation of
the hardware where as the control unit operates outdoors. The outdoor units
must be fully enclosed and protected from the climate changes for the safety
of the hardware
