Abstract

The utility model relates to an intelligent fireproof anti-theft alarm system which comprises a power supply module and a microprocessor module, wherein the microprocessor module is connected with an infrared detection module, a smoke detection module and a motor drive module; and the microprocessor module is also connected with a wireless transceiving module and an automatic dialing module. When a user needs protection, a wireless transmitting end transmits a defense signal; and after a wireless receiving end receives the corresponding signal, the system enters a defense state and starts sensors to work. If the infrared detection module detects that someone enters in the defense period, the entry can be considered as an illegal invasion; when the signal processing confirms the illegal invasion, the microprocessor module calls the automatic dialing module and starts the motor drive module, and meanwhile, the microprocessor module continuously takes samples from the smoke detection module and also calls the automatic dialing module if the smoke exceeds the preset safety margin.

Embodiment:

Power module: as shown in Figure 2, when Atmega16 was installed on user side, total system work during considered power down simultaneously, used standby power supply that system is supplied power when also how considered introduced user side with voltage, made that system is unlikely to quit work.

The AD sampling function that directly use MCU to carry this moment when the system voltage sampled value is lower than 2V, is sent a high level from MCU; Amplify the rear drive amplifier by triode, standby power supply inserts, and when sampled value is higher than 2V; Relay is discharged, to break off standby power supply.220V is netted through the transformer step-down in the city, behind the bridge rectifier, after resistance R 1, R2 dividing potential drop, obtain other module voltage after the process stabilivolt voltage stabilizing of resistance R 1 two ends, obtain the 5V power supply that supplies single-chip microcomputer to use after other end process D6 isolation, 7805 voltage stabilizings.

Infrared detection module 2: as shown in Figure 3, receive the infrared signal that human body sends and convert faint low frequency electric signal to by pyroelectric infrared sensor, deliver to the comparer that other two passages of LM253 constitute after wherein two passage amplifiers are amplified the low frequency small-signal of sensor through LM253; Reference voltage is by R5; VD1, the decision of VD2 dividing potential drop; Final when the sensor transmissions signal, the high level that inserts signal from INT0 triggers interruption.Reported to the police by automatic dial module in the interrupt service routine, call motor drive module simultaneously, opposite house carries out deadlock, further improves anti-theft effect.

Smoke Detection module 3: as shown in Figure 4; The MS5100 smoke transducer;

is its working power;

Figure 201120464369X100002DEST_PATH_IMAGE002

is heating power supply;

is sensor resistance; During operate as normal;

; is+5V; When smokescope just often,

stable with 2 ~ 2.7V.Use the AD sampling function of atmega16; to MS5100 detects; Explanation has the condition of a fire when surpassing 3V as

, and makes corresponding processing and reach jamproof fire detection function.

When the antenna wireless receiving and dispatching is assigned when deploying troops on garrison duty order system; MS5100 is powered up work; Output voltage is introduced the AD sampling channel of atmega16; The input of use difference; pin of atmega16 links to each other with digital outage source through the LC network, suppresses analogue noise.When sampled result surpasses safety margin continuously, send the application of transmission dtmf signal to atmega16, and make MT8888 carry out analog dialup telephone wire, turn to automatic dial module 6.
