Description
Technical field
The present invention relates to modern electronic technologies, more particularly to a kind of SCM Based intelligent fire alarm system and side
Method.
Background technique
Fire is due to a kind of nature out of control and initiation and the social disaster of burning.Fire certainly will will cause once occurring
According to the statistics made by the departments concerned, China occurs fire about 40,000, more than dead 2000 to different degrees of personal injury and property loss every year
People hurts 3000~4000 people, more than 10 hundred million yuan of direct property loss caused by annual fire.Hangzhou nurse in 2017 sets on fire
Case also exposes current social fire disaster emergency measure presence while causing online friend for relations problems between employer and nurse
Huge problem.In face of fire, alarm system loss caused by reducing fire plays irreplaceable role.
Summary of the invention
The present invention is directed in view of the above-mentioned problems, proposing a kind of SCM Based intelligent fire alarm system and method.
Technical program of the present invention lies in:
SCM Based intelligent fire alarm system, including single-chip microcontroller, sensor module, alarm module, data disaply moudle
And key module, the sensor module, alarm module, data disaply moudle and key module respectively with single-chip microcontroller
Realize connection；Wherein, the single-chip microcontroller is AT89C51 single-chip microcontroller.
The sensor module includes smoke sensor device, temperature sensor, amplifying circuit and A/D converter, described
Smoke sensor device and temperature sensor connect respectively with amplifying circuit, A/D converter one end and amplifying circuit are another
End is connect with single-chip microcontroller.
The temperature sensor be according to SCM Based intelligent fire alarm system described in claim 1,
It is characterized in that: thermocouple temperature sensor Pt100.
The smoke sensor device is novel ion formula smoke sensor device HIS-07.
The A/D converter is A/D conversion chip TLC549CP.
The alarm module is buzzer and LED light.
A kind of SCM Based intelligent fire alarm method uses SCM Based intelligent fire report as described above
Alert system, the process are as follows:
(1) the Initial Stage of Fire stage alarms
Fire early period of origination would generally generate smog because combustibles are smouldered, this stage due to there is no open fire, for smokescope
It is detected, when monitoring smokescope exception, the warning to indicate smokescope exception will be flashed by LED lamplight signal
Message is commonly seen light alarm it can be found that fire source and putting out, therefore in order to avoid big since the intensity of a fire is relatively small at this time
Scale is panic, and buzzer does not work at this time；
(2) fire shaping stage is alarmed
Fire, which continues development, will generate open fire, and since open fire occurs, temperature rapid increase, while smokescope declines；Work as system
When detecting that the rapid increase of temperature exists simultaneously smog, illustrate that fire has occurred and that, the alarm that need to be more warned, at this time
Device will generate the flashing of LED lamplight signal, and start buzzer warning.
The technical effects of the invention are that:
The present invention is directed to general fire scenario, a kind of SCM Based intelligent fire alarm system is proposed, with AT89C51
Series monolithic is master control, is completed pair using Pt100 temperature sensor and HIS-07 smoke sensor device double check mode
The design of intelligent fire alarm system proposes that " light is believed according to the Initial Stage of Fire stage fire characteristics different with fire shaping stage
Number alarm " and " optical signal+buzzer warning " two kinds of type of alarms, make fire alarm have more sensitivity and accuracy.
Detailed description of the invention
Fig. 1 is that the present invention is based on the schematic illustrations of the intelligent fire alarm system of single-chip microcontroller.
