Description
Technical field
The present invention relates to technical field of smoke alarm, more particularly to a kind of smog alarm method and smoke alarm unit.
Background technology
In traditional Smoke Detection flow, general using detection method is interrupted, i.e. smog in real time in monitoring air is dense
Degree, as long as the smokescope obtained is more than the default density, that is, judge that current smokescope is exceeded, so as to trigger early warning mechanism,
But in smog evanishment, the smog that smoke detection intracavitary retains may cause the inaccurate situation that detects and alarm；Easily
Incorrect alarm signal is triggered, causes that people's is alarmed.
In the prior art also have and to be detected by the way of timing detects in air and smokescope, although this method can be
Solve the problems, such as alarm when above-mentioned smog dissipates to a certain extent, dissipated the delivery time for smog, but use timing to detect
Mode there may be the hidden danger of alarm not in time again.Smog dissipates the time generally required up to a few minutes, but before fire
A few minutes are especially precious and should be subject to carefully using having avoided that more major accident occurs, therefore are detected using this mode
And the needs of can not meeting us.
The content of the invention
The purpose of the present invention be overcome in above-mentioned background technology it is insufficient, there is provided one kind detection and alarm mechanism more flexibly and
Accurately, timely smog alarm method and smoke alarm unit, it may be either that smog dissipates and set aside some time, also solve the problem that alarm is too late
When the problem of, actual use demand can be better met.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme：
A kind of smog alarm method, is comprised the steps of：
S1. smoke signal is obtained in real time, and detects the smokescope value of smog in the smoke signal of acquisition, while minute book
The secondary time for obtaining smoke signal；
S2. judge whether the smokescope value exceedes default smoke density threshold value, if the smokescope value is not less than smog
Concentration threshold, then judge that current smokescope is normal, and return to step S1, otherwise, into step S3；
S3. generate smog alarm trigger signal and send alarm signal, monitoring current time obtains cigarette in step S1
The time interval value of fog signal, and enter timing monitoring flow S4；
S4. smog is obtained again when current time reaches time value A apart from the time interval value of last time acquisition smoke signal
Signal, and the smokescope value of smog in the smoke signal of acquisition is detected, while record this time for obtaining smoke signal；Between
It can be set every time value A according to the average time that in real space, smog dissipates, so as to be the smog dissipation outflow after alarm
Time, the problem of avoiding the occurrence of repetition of alarms；
S5. judge whether the smokescope value exceedes default smoke density threshold value, if the smokescope value is not less than smog
Concentration threshold, then judge that current smokescope recovers normal, and return to step S1；Otherwise, alarm signal is sent again and is returned
Step S4；
Wherein, monitoring and Monito ping at intervals both of which in real time are specifically set with this method, it is right after alarm mechanism is triggered
By the way of Smoke Detection in air is detected using interval, the alarm that can avoid repeating always brings unnecessary fiber crops to user
It is tired, meanwhile, real-time monitoring pattern is returned to after smokescope recovers normal, to monitor the smokescope in air in time.
Further, the interlude value A is five minutes.
Meanwhile the invention also discloses a kind of smoke alarm unit, comprising smoke detector, Smoke Sensor, controller,
Timer and alarm, the smoke detector electrically connect with Smoke Sensor, timer, controller respectively with smoke detection
Device, Smoke Sensor, timer and alarm electrical connection；
The smoke detector is used to obtain smoke signal, and the smoke signal of acquisition is transferred into Smoke Sensor, and
The pattern that smoke detector obtains smoke signal includes real-time obtaining mode and interval acquiring pattern, wherein, real-time obtaining mode
To be obtained in real time to current smoke signal, interval acquiring pattern is to obtain a smog at interval of an interval time value A
Signal；
The Smoke Sensor is used to detect the current smokescope value in the smoke signal of smoke detector acquisition, and will
The current smokescope value detected is transferred to controller；
The alarm will send alarm signal when entering alarm mode, timer is used to record smoke detector acquisition cigarette
Time value during fog signal；
Smoke density threshold value is preset with the controller, controller is used for the current smog of Smoke Sensor transmission is dense
Angle value is compared with smoke density threshold value, so as to judge whether current smokescope is normal；
Wherein, if current smokescope value is not less than smoke density threshold value, controller then controls smoke detector with real-time
Obtaining mode obtains smoke signal；If current smokescope value exceedes smoke density threshold value, controller then controls alarm to enter
Alarm mode, and smoke detector is controlled with interval acquiring pattern acquiring smoke signal.
Further, the interval time value A is five minutes.
Further, the alarm is made up of buzzer and/or flashing lamp.
The present invention compared with prior art, has following beneficial effect：
Two kinds of monitoring and Monito ping at intervals in real time are specifically set with the smog alarm method and smoke alarm unit of the present invention
Pattern, after alarm mechanism is triggered, by the way of being detected to the Smoke Detection in air using interval, the report repeated always can be avoided
Police brings unnecessary trouble to user, meanwhile, real-time monitoring pattern is returned to after smokescope recovers normal, to supervise in time
The smog alarm method of the smokescope present invention in control air and the detection of smoke alarm unit and alarm mechanism are more flexible
And it is accurate, timely, it may be either that smog dissipation is set aside some time, also solve the problem that the problem of alarming not in time, reality can be better met
Use demand.
