Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of Intelligent fire alarm system, comprise: smoke transducer, temperature sensor, microprocessor, described microprocessor is connected with power supply, smoke transducer, temperature sensor are connected on microprocessor, smoke transducer, temperature sensor are connected with power supply simultaneously, described microprocessor is connected with display module, alarm module, communication module, maneuvering system, described display module, alarm module, communication module are connected with power supply.
Described temperature sensor adopts DS18B20 temperature sensor.
Described smoke transducer adopts MQ-2 smoke transducer.
Described communication module comprises NRF24L01 wireless communication module, gsm wireless communication module.
Described alarm module comprises audible-visual annunciator and phonetic alarm.
Principle of work of the present utility model is: the smoke transducer of sensing point and temperature sensor pass to microprocessor the data detected, and gives display section by calculating relatively data.Wherein smoke transducer MQ-2 to liquefied gas, propane, hydrogen highly sensitive, also very desirable to the detection of rock gas and other combustible vapor, simultaneously also very sensitive to the detection of smog.So can early warning also can report to the police.Temperature sensor DS18B20 real-time detection temperature value, is shown by AD conversion.
Wherein, when the data value of sensor detection exceedes alarm door limit value and namely inspires warning device, sound and light alarm part is wherein reported to the police to resident family, phonetic alarm device reports to the police on duty some personnel, and pass through the position of NRF24L01 wireless communication module display alarm on the computer of point on duty, when fire occurs, press the GSM button in communication module, automatically can make a phone call to send short messages to fire prevention and control center, the particular location of fire is described automatically.
The features such as OLED display screen module has little power consumption, long service life in addition, cost is low, brightness is high, fault is few, visual angle is large, visual range is far away.Further, this display screen has the following page: one is show current temperature value above display screen, aerosol gases concentration value.Two be report to the police time, display screen interface is being dodged always, point out user.Three is that pattern is arranged, and have single household and detect, centralized detecting, superpower detection, and threshold value changes the interfaces such as display.Wherein single household detects and can carry out sensor detection to unique user, and centralized detecting is for carry out sensor detection to all users, and superpower being detected as not only is carried out sensor detection to all users but also carried out the detection of whole warning system fault.The change of all these patterns can be changed by NRF24L01 radio communication.
The all power supplies of this system come from user's power supply and rechargeable battery.When normally detecting at ordinary times, power supply used is user's power supply, reliable and stable.When fire occurs, or fortuitous event causes user's power-off, and internal system automatically switches to internal battery by single channel relay and powers, and keeps not power-off.The overall power consumption of native system is considerably less, and usual accumulator can keep a few week of powering, and power unit has pilot lamp, and user is the need of charging in prompting.
The maneuvering system that native system has can be automatic when fire occurs, or Non-follow control fire extinguishing system, can reach the effect of quick extinguishing or prevention fire spreading like this.
The utility model installs system sensor probe at place of Mei Wei resident family divides and display section, carries out information interaction, such as check the sensor probe value etc. of current resident family by radio communication and point on duty.The gsm module of point on duty can carry out information interaction with fire prevention and control center, fire occur time and alarm.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
