When wireless optical electric-type smoke alarm carries out detection, utilize the smog that Initial Stage of Fire is produced by light scattering principle
Detect, utilize 433MHz communication frequency band to carry out signal transmission, specifically include following steps:
(1) learning process: in order to distinguish the smoke alarm of each fire-fighting main frame association, utilized distant before normal work
Each detector study coding given by control device, and encoded content includes fire-fighting host address, detector building, unit, room number, detection
The information such as device sequence number.Test button presses for more than 1s, and wireless radio frequency modules enters learning state；If detector learning success,
Remote controller can receive the answer signal that wireless radio frequency modules sends, and the buzzer of detector can send prompt tone, prompting ground simultaneously
Location learning success, each detector, by study, obtains the address information of self, is provided with the function of identification, if learned
Practising unsuccessful, remote controller can not receive answer signal, and the buzzer of detector does not send prompt tone simultaneously, repeats above-mentioned length by test
Button operation, goes successively to learning state；If test button is pressed less than 1s on the contrary, detector is put into test job mould
Formula, detector sends out test signal by wireless radio frequency modules.
(2) smoke signal and battery voltage signal gatherer process: in order to reduce system power dissipation, uses time-sharing handling method；
Detector is in normal operating conditions, and when non smoke in environment, infrared light reception diode does not receives infrared light emission two pole
The infrared light that pipe sends, the sample circuit of subsequent smoke AD acquisition module without change in electric, then the sampling period of smoke signal
For 8S, carry out a smoke signal AD sampling every 8S；When there being smog in environment, smoke particle makes infrared light send out in entering labyrinth
Penetrating the infrared light that diode sends to scatter, the intensity of the infrared light of scattering and smokescope are some linear, follow-up
Sample circuit changes, and judges that these variable quantities are confirmed whether fire alarm by single-chip microcomputer, if double collection
AD value higher than the threshold value set, then enter alert status, the sampling period changes 2S into, is shortened by the sampling period and improves smog
The accuracy of detection；Single-chip microcomputer is analyzed by gathering the data come, and determines whether that the condition of a fire occurs, once confirms fire
Alert, alarm lamp is lighted, and is started buzzer warning, utilizes wireless communication technique simultaneously, fire signal is uploaded to fire-fighting
Main frame, fire-fighting main frame notifies user by making a phone call or send short messages, start simultaneously the auxiliary devices such as wireless switching start water pump or
It is fire hydrant, reaches the effect of fire-fighting link；
(3) active reporting process: in order to verify that detector is in normal operating conditions, and its work state information is uploaded
To fire-fighting main frame, in the course of the work, detector passes through wireless radio frequency modules (Random event at regular intervals to smoke alarm
Part) active reporting data, data message includes whether having the condition of a fire to occur or working battery is the most under-voltage and whether detector is located
In the information of normal operating conditions, wireless radio frequency modules is while reported data, and the display lamp of detector is glittering, reminds user
Detector is in normal operating conditions.
Above-mentioned state carry out step smoke signal gatherer process while, cell voltage is also sampled by AD acquisition module,
Its sampling period is five minutes, if the voltage signal collected is less than normal working voltage, buzzer is issued by under-voltage prompting,
User is reminded to change battery in time, it is to avoid normally to work because battery undervoltage affects detector, bring unnecessary trouble；
When detector is extractd by artificial or other reasons, owing to installing plate contacts electrode approach with base plate employing, work as spy
Survey device is by when installation site is taken away, and contact electrode points disconnects with shell fragment, and single-chip microcomputer can't detect contact electrode signal, by right
Detection signal analysis, it is believed that detector is in abnormal operating state, alarm and/or display lamp and sends warning reminding signal,
Detector is in abnormal operating state in time and is uploaded to fire-fighting main frame by detector by wireless radio frequency modules, and main frame can be very
Know which detector is taken off soon.
