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
The present invention relates to detection field, particularly a kind of smoke alarm.
Background technology
Existing office building corridor is equipped with smoke alarm, causes but the triggering of a lot of situation alarms is smog due to smoking, has caused unnecessary fear.
Summary of the invention
The present invention proposes a kind of smoke alarm, has solved in the prior art smoke alarm by the problem of the smog false triggering of smoking.
Technical scheme of the present invention is achieved in that
A kind of smoke alarm comprises: be arranged on the smoke detector at corridor and place, toilet, output alarm signal when the smog value exceeds standard; Single-chip microcomputer is connected to described smoke detector, and after receiving described alerting signal, the triggering timing device begins the timing operation, and alerting signal is maintained to timing time then, the output excitation signal; Alarm is connected to the output terminal of described single-chip microcomputer, carries out alarm operation when receiving excitation signal.
Alternatively, described single-chip microcomputer is 51 single-chip microcomputers.
Alternatively, described alarm is loudspeaker.
Alternatively, described alarm is the pilot lamp that is arranged in Control Room.
The invention has the beneficial effects as follows: effectively reduced the probability of false alarm, alarm reliability is high.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of a kind of smoke alarm of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, a kind of smoke alarm, comprise: the smoke detector that is arranged on corridor and place, toilet, output alarm signal when the smog value exceeds standard, as the first smoke detector 10 in Fig. 1, with the second smoke detector 20 and the 3rd smoke detector 30 of the first adjacent setting of smoke detector, the quantity of smoke detector is decided according to area and the structure of corridor and toilet, and the smoke detector in Fig. 1 is only schematic; Single-chip microcomputer 40 is connected to smoke detector, after receiving alerting signal, and the 50 beginning timing operations of triggering timing device, alerting signal is maintained to timing time then, the output excitation signal; Alarm 60 is connected to the output terminal of single-chip microcomputer 50, carries out alarm operation when receiving excitation signal.Perhaps, when the first smoke detector 10 sends alerting signal, when single-chip microcomputer 50 was received alerting signal with the second smoke detector 20 of the first smoke detector 10 adjacent settings and the 3rd smoke detector 30 simultaneously, single-chip microcomputer 50 is triggering timing device 50 not, and directly exports excitation signal.
when the people is arranged in corridor smoking, the smog that smoking is dispersed can only trigger at most a smoke detector, for example the first smoke detector 10 has detected the smog value and has exceeded standard, send alerting signal, and the smog value that the second adjacent smoke detector 20 and the 3rd smoke detector 30 detect does not exceed standard, single-chip microcomputer 50 triggering timing device 50 beginning timing operations, for example timing time is 5 minutes, and A Cigarette Without You usually can be more than 5 minutes, when 5 minutes timing times then, the smog value is lower than standard, single-chip microcomputer 50 does not send excitation signal, the situation of having got rid of false triggering.
Preferably, single-chip microcomputer 50 is 51 single-chip microcomputers, and alarm 60 can be loudspeaker, also can be arranged on the pilot lamp in Control Room.
The invention has the beneficial effects as follows: effectively reduced the probability of false alarm, alarm reliability is high.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
