I. INTRODUCTION
With the computer technology and control technology and
communicational technology’s development, people’s living
standard has improved increasingly. People's living
conditions have changed, Such as the living environment’s
curity and how comfortable they feel. So the intelligent
residential building’s automatic emerge as the times require.
Intelligent residential must have safety precautions, anti-theft
alarm, fire alarm, toxic gas leakage automatic alarm and
emergency call. It is able to implement remote control for the
key equipment power. In recent years, with the progress of
technology and economy, the electronic anti-theft alarm
system has rapid development and a very wide application.
Now it does not only apply in many important government
departments, but also apply in the family.
In-depth study on various alarm device, we have designed
intelligent residential curity alarm and remote control
system on the basis of single chip computer. The system is
bad on 89C51 single chip computer, has intelligent
residential burglar alarm, emergency call alarm, fire alarm,
toxic gas leakage automatic alarm and remote control[1]. It is
able to call the police hotline number. It is able to u voice
alarm and show alarm occurred address. Urs can t up and
modify password for it. It can be recordable and voice
suggestion and make u of the telephone to remote control.
Calling when is not at home, it can u password to enter

electronic appliance.
The system makes u of communication equipment to
realize multi-channel detection, scene alarm, emergency
alarm, fire alarm and toxic gas leakage automatic alarm. It
realizes remote voice alarm function through the automatic

dial-up telephone[2]. It directly parallels on the telephone
lines, then may be ud. Before ud, ur will be required to
install the detection device in place where being watched by
people. It must be t up alarm telephone number, recorded
voice alarm. The alarm system has design innovation,
multiply function, low cost, high reliability and so on.
itachiII. SYSTEM COMPONENT
Intelligent residential curity alarm and remote control
system constitutes as shown in figure 1. The system is
through telephone interface circuit and telephone network to
link up. 89C51 single chip computer dominates by MT8880
Dual Tone Multi-frequency (DTMF) codec with the
大学英语四六级准考证打印入口telephone network to exchange informationthe coma[3]. When the
detection of dangerous situations, the dangerous situation
coded signal transfer from the corresponding detection
module through the antenna to master chip. The master chip
brings the corresponding alarm information according to
received signal. This part is to complete by the voice interface
circuit, which us ISD1420. After urs call the number of
system, urs can control appliances according to sound by
the voice interface circuit.
The system components are made up of detecting circuit,
wireless transmitter-receiver circuit, telephone interface,
voice circuit, DTMF codec circuit, telephone signal detection
shooflycircuit and the main control circuit. Each module is described
hpfas follows:
