Remote Control Digital Display System Based on
Single Chip Microcomputer
ABSTRACT
In recent years, alarm detects more and more signal types and requires more
intelligence in order to meet the convenience of human life needs. Alarm can sense
infrared signal, ultrasonic signal, gravity signal, vibration signal and remote
control signals. This paper designs a safe, practical and convenient burglar alarm
on the analysis of several common alarm functions and the actual situation.
This paper describes the research and development of the alarm, the advantages
and the disadvantages of several different alarms and theirs popularity. The paper
also analyzes the detection principles and the physical mechanisms of the popular
alarms. And this paper chooses remote control signal, infrared signal and
temperature signal as the detection signals.
Infrared technology is a very mature technology and human eyes can not see
infrared light. It can be used under different weather conditions with good
concealment, and strong anti-interference ability. This kind of anti-theft alarm
system is widely used in homes, offices and other occasions. This design uses
infrared signal as a detection signal.
Temperature signal is most commonly used in daily life and used in most warning
systems. Particularly, temperature signal is an essential signal in the fire alarm
device. Temperature signal is one of the most intuitive parameters in the specific
environment. It can be monitored to judge the spot situation in order to provide
the basis for subsequent operations.
Remote control technology is highly attention with the development of the
intelligent alarm. Remote control technology can control and monitor remote object.
Remote control technology can not only control remote alarm equipment, but also
monitor the basic situation of the terminal. It is used in alarm system because
of the maturity of such technology.
This anti-theft alarm system selects the remote control signal, the infrared
signal and the temperature signal as monitoring signals. Remote control signal
