Remote home fire and burglar alarm system based on GSM communication module

technical field

The utility model relates to an alarm system, which belongs to the technical field of monitoring fire prevention and anti-theft alarm.

Background technique

As the material life of residents has become more colorful, liquefied petroleum gas and coal gas have entered thousands of households, and various home appliances have also been popularized. These products of social development have also brought huge fire hazards. In the event of a sudden fire, serious life injuries and property damage to residents will follow. Moreover, due to the great increase in the mobility of the social population, its public security problems have also become prominent. In many urban communities, acts of robbery and theft have increased. The way, that is, the mode of anti-theft windows plus anti-theft doors, and such anti-theft measures are difficult to guarantee the safety of family property. Therefore, people urgently need an unmanned intelligent home fire prevention and anti-theft alarm system. No matter when, as long as there is an alarm situation, the information will be quickly transmitted to the owner, which can effectively kill the alarm situation in the cradle, reduce losses and ensure safety. . At present, most of the various intelligent alarm devices on the market are difficult to promote due to high cost, single function or poor usability. These low-cost alarm equipment are difficult to win the favor of users. For example, many banks and large stores often use automatic alarms. Multiple anti-theft systems such as monitoring and automatic door and window locks have strong anti-theft and robbery capabilities, but the overall price is expensive and unaffordable for ordinary owners. Therefore, the small-scale system formed by the single-chip microcomputer is a low-cost, reliable intelligent family fire prevention and anti-theft alarm system that is really suitable for family use.

Detailed ways

Specific embodiment one: the present embodiment is described below in conjunction with Fig. 1, and the remote home fire prevention and anti-theft alarm system based on the GSM communication module described in the present embodiment includes a core control module 1, a shock sensor 2, an infrared sensor 3, a temperature sensor 4, and a smoke sensor 5. GSM communication module 6, sound and light alarm module 7, power supply module 8 and peripheral function module 9, etc.

The core control module 1 includes a single-chip microcomputer and its minimum system peripheral circuit, and the single-chip microcomputer adopts an AT89S52 single-chip microcomputer.

Described vibration sensor 2 adopts SW-18010P sensor, is used for collecting the vibration signal of door and window.

The infrared sensor 3 uses a RE200B pyro-infrared probe, which is used to collect infrared signals of illegal intruders in the room.

The temperature sensor 4 adopts a DS18B20 digital temperature sensor for collecting indoor temperature signals.

The smoke sensor 5 adopts the MQ-2 smoke concentration sensor, and the MQ-2 smoke sensor can not only detect smoke particles, but also detect flammable gases such as methane, propane, butane, liquefied petroleum gas, and hydrogen.

The 6 GSM communication modules adopt the TC35 module, and the TC35 can provide communication services such as voice, fax, short message and data, and the head of the household can control the opening and closing of the system through the TC35 module.

The sound and light alarm module 7 includes a buzzer and a luminous LED. When the system terminal main board is in the fortified state, when any probe triggers an alarm, the buzzer sounds continuously and intermittently, and the luminous LED flickers for five minutes.
