Keywords: DTMF automatic dial-up password control; intelligent alarm system; CLC number: TN915. 5 Document No.: A 1 introduction of system function In order to create a peaceful living environment for residents, residential areas generally used in the intelligent alarm system. This paper introduces a MCS-51 singlechip [1], DTMF signal transceiver chip MT8888, integrated voice chip ISD1420 and HD44100 LCD display driver module together organically, automatic dialing anti-theft fireproof connected to the telephone network alarm. The alarming system preventive function by the user through the keyboard to set the panel of the host computer, when the monitored point theft or fire accident, the accident will alarm signal to the system, the system automatically through the telephone network to the management center or user paging. Alarm control host and between detector with wireless mode, wireless detector comprises a wireless infrared / microwave detector, wireless composite fire detector or with emergency alarm wireless the remote control. 2 system hardware design Alarm system diagram as shown in Figure 1, the alarm system is divided into three parts, namely the user end user end detector part, automatic alarm and monitoring management center part. Different positions of the front detector part can be placed in the field, can achieve multiple control purposes; the user terminal automatic alarm in the user's home in the monitoring center; management to the automatic alarm acquisition alarm monitoring and management information. 2.1 user terminal detector The detector consists of infrared / microwave detector and composite fire detector, detection of theft and fire respectively. 2.2 user terminal automatic alarm Automatic alarm automatic dialing circuit, including DTMF code control circuit, speech detection and alarm circuit, a telephone interface circuit, power supply circuit As well as the keyboard and display circuit. 2 2.1 automatic dialing alarm part Journal of Henan Normal University (Natural Science Aug 2004). In 2004 August Received date: 2004- 02- 17 Author introduction: Wang Fang (1972~), female, Henan Linzhou, Henan Normal University lecturer, master, research direction: application of sensor and signal processing. 2 MT8888 chip not only has the DTMF signal receiving function, but also has the function of the telephone signal detection [3], it can be convenient and MCS51 systemMCU interface. The ISD1420 is a monolithic solid-state voice integrated circuit, a voice recorded, can save more than 10 A, can repeatedly record 100000 times, the recording time of up to 20 s. when you press the REC key, recording, data storage from 0 until the memory address, full or release the button. When you press the PLAY key, then begin playback, straight to PLAY release or memory is exhausted. received date: 2004- 02- 17 Author introduction: Wang Fang (1972~), female, Henan Linzhou, Henan Normal University lecturer, master, research direction: application of sensor and signal processing. Fig. 1 alarm system diagram The dialing circuit, a voice circuit needs a telephone interface circuit connected with the outside world through broadcast to ensure dial-up circuit of DTMF signal transmission and voice circuit of speech signal is normal, system settings and polarity protection circuit, composed of a diode bridge, no matter how users will outside line access LINE IN port, can ensure that the 2 Journal of Henan Normal University (Natural Science Aug 2004).

Type the password value compared with the original password password buffer values, the same service, the user can enter. When six consecutive error input, automatic alarm in alarm condition, alarm signal cipher circuit is provided with 90 s timing. Interrupt control signal, avoid long time operation is not valid. The keyboard is a device used to complete the system state display and all the functions, the keyboard can be password protection, removal, bypass and programming to the system set up, such as the preset various delay time preset alarm, telephone, communication format and all kinds of report messages and trigger an emergency alarm to probe state, power status and the address status has fault display and alarm display. When removal zone above the exhibit of lanterns lit instructions automatically, said the sector has been abandoned, can pass, even if there are warning the probe signal, the system does not send alarm signal to start. 2.2.3 power supply Section The ICL7673 is a monolithic CMOS standby power integrated circuit, when in normal work, the main power supply through a resistor and silicon diode Juan of nickel-cadmium battery charging current, the output voltage is mainly supply voltage. When the power grid blackout, the standby power supply to power supply on the system, the output voltage becomes standby power supply voltage value, can guarantee the normal work of the system in the main power failure. 2.3 the part of monitoring management center If the alarm signal, monitoring computer management center starts the alarm handler, issued a warning signal, the personnel on duty after receiving the alarm signal, must enter the police staff name, to exit the alarm status. The computer exits the alarm condition, alarm, report the date time, tenants, warning category, police staff name, alarm time the alarm information, alarm loading to files, for future inquiry. Police after the police report, fill in and stored in the computer, complete the whole process monitoring, alarm. Journal of Henan Normal University (Natural Science Aug 2004).

When the legitimate users leave, the main program Wait for a certain time, automatically into the fortified state. The main program timer watchdog process Order, make the system normal not to be reset. 3.2 dial-up control circuit, software design Figure 2 is a dial control module program flow chart, dial control software design is automatic The core of alarm, it completes Journal of Henan Normal University (Natural Science Aug 2004).

Taking into account the dial tone, tone, ring back tone, tone deposit Are you there. 4 the conclusion Residential anti-theft fire intelligent telephone alarm system is the use of the growing popularity of residential telephone Line to achieve the alarm function, the system can realize communication automation, computerization, anti-theft response Adaptation and home appliances remote [4]. At the same time, can be installed in residential medical help button And emergency help button, combined with the alarm system of medical care help system And emergency rescue system. When in use, you can also add a video recording system. When the alarm, Automatic startup automatic video recording, may constitute a very perfect monitoring alarm system. The system design is reasonable, reliable operation, improve the intelligent level of the housing security system.
