Abstract

The invention provides a smog alarm which solves the problem of spurious triggering caused by smoking of a smog alarm in the prior art. The smog alarm comprises smog detectors, a single chip and an alarm. The smog detectors are arranged at the positions of a lobby and a washroom, and output alarm signals when a smog value is overproof. The single chip is connected to the smog detectors, after the single chip receives the alarm signals, a timer is triggered to start timing, the alarm signals are maintained to the moment the timing time is up, and an excited signal is output. The alarm is connected to an output end of the single chip, and when the alarm receives the excited signal, alarm operation is conducted.

Description

technical field [0001] The invention relates to the detection field, in particular to a smoke alarm. Background technique [0002] Existing corridors of office buildings are equipped with smoke alarms, but the triggering of the alarms in many cases is caused by smoke from smoking, causing unnecessary panic. Contents of the invention [0003] The invention provides a smoke alarm, which solves the problem in the prior art that the smoke alarm is falsely triggered by smoking smoke. [0004] Technical scheme of the present invention is realized like this: [0005] A smoke alarm, comprising: smoke detectors arranged in corridors and toilets, which output an alarm signal when the smoke value exceeds the standard; a single-chip microcomputer, connected to the smoke detector, triggers a timer to start counting after receiving the alarm signal Operation, the alarm signal is maintained until the timing time is up, and the excitation signal is output; the alarm is connected to the ...
