Because the wireless remote monitoring system has
more and more application, a remote monitoring system
based on SMS of GSM is presented. Based on the total
design of the system, the hardware and software of the
system is designed. In this system, GSM network is a
medium for transmitting the remote signal. The system
includes two parts which are the monitoring center and
the remote monitoring station. The monitoring center
consists of a computer and a TC35 communication
module of GSM. The computer and TC35 are connected
by RS232. The remote monitoring station includes a TC35
communication module of GSM, a MSP430F149 MCU, a
display unit, various sensors, data gathering and
processing unit. The software of the monitoring center
and the remote monitoring station is designed by using
VB. The result of demonstration shows that the system can
monitor and control the remote communication between
the monitoring center and the remote monitoring station,
and the remote monitoring function is realized.
