煙感報警器的工作原理是什么？

煙霧是上升運動的，到達(dá)天花底下。煙感報警器通過煙發(fā)現(xiàn)火災(zāi)。在您沒有看到火苗或聞到煙味的時候，煙感器已經(jīng)知道了。它不停工作，一年365天，每天24小時，從不間斷。
The smoke rises and reaches under the smallpox. Smoke detection through fire alarm. When you don't see the flame or smell the smoke, the smoke sensor already knows. It works 24 hours a day, 365 days a year, without interruption.
在報警時，它發(fā)出尖嘯刺耳的聲音，直到煙霧散去。在真實的火災(zāi)中它一直工作到被燒毀。
At the time of alarm, it made a shrill sound until the smoke dispersed. In a real fire, it worked until it burned down.
民用住宅的獨立式煙感報警器共有兩種傳感器可供選擇：一種是離子傳感器，一種是光電傳感器。
There are two kinds of sensors for the independent smoke detector of civil residence: one is ion sensor and the other is photoelectric sensor.
火災(zāi)報警器使用方法
Application method of fire alarm
離子傳感器是通過測量空氣中的正負(fù)電荷的平衡來工作的。在傳感器內(nèi)部，有一小片放射性物質(zhì)，這種物質(zhì)能在感應(yīng)室內(nèi)流動的空氣中 產(chǎn)生一股微小的電流。在線路板上，有一個電腦芯片用來監(jiān)測這股電流。
Ion sensors work by measuring the balance of positive and negative charges in the air. Inside the sensor, there is a small piece of radioactive material, which can produce a small current in the air flowing in the sensing room. On the circuit board, there is a computer chip to monitor the current.
當(dāng)煙霧粒子進(jìn)入到感應(yīng)室后，就會擾亂那里的正負(fù)電荷的平衡，同時也會使這股電流發(fā)生變化。當(dāng)煙霧逐漸加重，正負(fù)電荷的不平衡性就會加強。當(dāng)這種平衡性達(dá)到一定的限度，喇叭就會響起。
When smoke particles enter the induction chamber, they will disturb the balance of positive and negative charges there, and change the current. When the smoke gets heavier, the imbalance between positive and negative charges will be strengthened. When this balance reaches a certain limit, the horn will sound.
光電傳感器是通過一束光和一個光的感應(yīng)器來測量煙的濃度的。該裝置設(shè)計的時候，光束是偏離感應(yīng)器的。當(dāng)煙霧進(jìn)入到感應(yīng)室后，煙霧粒子會將部分光束散射到感應(yīng)器上。當(dāng)煙霧的濃度逐漸加重，就會有更多的光束被散射到感應(yīng)器上。當(dāng)?shù)竭_(dá)傳感器的光束達(dá)到一定的程度，蜂鳴器就會響起。
Photoelectric sensor measures the concentration of smoke through a beam of light and a light sensor. When the device is designed, the light beam deviates from the sensor. When the smoke enters the sensing chamber, the smoke particles will scatter part of the light beam onto the sensor. When the smoke concentration increases gradually, more light beams will be scattered to the sensor. When the light beam reaching the sensor reaches a certain degree, the buzzer will sound.
