Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The method comprises the steps of obtaining a smoke concentration value detected by a smoke sensor; when the smoke concentration value is larger than a first threshold value, the humidity sensor accelerates to detect a humidity value; judging whether the acceleration of the humidity value is larger than a second threshold value or not; when the acceleration rate of the humidity value is larger than a second threshold value, the first threshold value is adjusted to a third threshold value, then the smoke concentration value is continuously detected, and when the acceleration rate of the humidity value is smaller than or equal to the second threshold value, an alarm instruction is sent to the smoke alarm. According to the embodiment of the invention, whether the reason for generating the smoke is water vapor is determined by judging whether the acceleration of the humidity value is larger than the second threshold value or not, when the acceleration of the humidity value is larger than the second threshold value, the smoke alarm is determined to be water vapor, the sensitivity of the smoke alarm is reduced, the smoke concentration value is continuously detected after the first threshold value is adjusted to be the third threshold value, and when the acceleration of the humidity value is smaller than or equal to the second threshold value, the smoke alarm is determined to be fire smoke and an alarm instruction is sent to the smoke alarm, so that the smoke alarm does not immediately send an alarm signal when detecting a large amount of water vapor, and the occurrence of false alarm of the smoke alarm is effectively reduced.
Example one
As shown in fig. 1, an embodiment of the invention provides a smoke alarm management method, the smoke alarm comprising a smoke sensor and a humidity sensor, the method comprising:
step S1, obtaining a smoke concentration value detected by the smoke sensor;
step S2, when the smoke concentration value is larger than a first threshold value, the humidity sensor accelerates to detect a humidity value;
step S3, judging whether the acceleration of the humidity value is larger than a second threshold value;
step S41, when the acceleration rate of the humidity value is larger than a second threshold value, adjusting the first threshold value to a third threshold value and then continuing to detect the smoke concentration value;
and step S42, when the acceleration rate of the humidity value is smaller than or equal to a second threshold value, sending an alarm instruction to the smoke alarm.
It will be appreciated that the humidity value may be due to rain and fog weather or a humid environment, and may also be due to water vapour. The first threshold is a smoke concentration value preset by the factory of the smoke alarm or self-set by a user, and is generally preset by a manufacturer when the smoke alarm is delivered. The second threshold is a humidity acceleration value preset by the factory of the smoke alarm or set by the user according to the local environment, and is generally preset by the manufacturer when the smoke alarm is delivered. When the smoke concentration value detected by the smoke sensor is larger than a first threshold value, the humidity sensor accelerates to detect the humidity value, when the acceleration of the humidity value is larger than a second threshold value, the humidity value is certainly caused by water vapor, the sensitivity of the smoke alarm is reduced, the smoke concentration value is continuously detected after the first threshold value is adjusted to be a third threshold value, the third threshold value is larger than the first threshold value, and an alarm signal is not sent out temporarily; and when the smoke concentration value detected by the smoke sensor is larger than a first threshold value, accelerating the detection of the humidity value by the humidity sensor, if the humidity value is caused by rain and fog weather or a humid environment, accelerating the humidity value slowly, and if the accelerating of the humidity value is smaller than a second threshold value, sending an alarm instruction to the smoke alarm. After receiving the alarm instruction, the smoke alarm gives an alarm by sending out an alarm sound or/and sending out signals such as a flashing light and the like.
The smoke concentration value described in the present invention includes a dense smoke concentration value detected by the smoke sensor and a humidity value detected by the humidity sensor, and is a sum of the dense smoke concentration value detected by the smoke sensor and the humidity value detected by the humidity sensor.
According to the embodiment of the invention, whether the reason for generating the smoke is water vapor is determined by judging whether the acceleration of the humidity value is larger than the second threshold value or not, when the acceleration of the humidity value is larger than the second threshold value, the smoke alarm is determined to be water vapor, the sensitivity of the smoke alarm is reduced, the smoke concentration value is continuously detected after the first threshold value is adjusted to be the third threshold value, and when the acceleration of the humidity value is smaller than or equal to the second threshold value, the smoke alarm is determined to be fire smoke and an alarm instruction is sent to the smoke alarm, so that the smoke alarm does not immediately send an alarm signal when detecting a large amount of water vapor, and the occurrence of the alarm condition of the smoke false alarm is.
In an alternative embodiment of the invention, as shown in fig. 2, the method comprises:
step S1, obtaining a smoke concentration value detected by the smoke sensor;
step S2, when the smoke concentration value is larger than a first threshold value, the humidity sensor accelerates to detect a humidity value;
step S3, judging whether the acceleration of the humidity value is larger than a second threshold value;
step S41, when the acceleration rate of the humidity value is larger than a second threshold value, adjusting the first threshold value to a third threshold value and then continuing to detect the smoke concentration value;
step S5, judging whether the humidity value is smaller than a fourth threshold value and whether the smoke concentration value is larger than a first threshold value;
and step S6, when the humidity value is smaller than a fourth threshold value and the smoke concentration value is larger than a first threshold value, sending an alarm instruction to the smoke alarm.
It can be understood that after a large amount of water vapor is detected, no alarm signal is sent, and after the water vapor is diffused, whether the diffusion is performed or not is judged according to the condition that whether the humidity value is smaller than a fourth threshold value, wherein the fourth threshold value is a humidity value preset by a factory of the smoke alarm or set by a user according to a local environment, and is generally preset by a manufacturer when the factory of the smoke alarm leaves. When the humidity value is less than the fourth threshold, it indicates that water vapor has diffused. And when the humidity value is smaller than a fourth threshold value and the smoke concentration value is larger than the first threshold value, determining that the smoke concentration value exceeds the standard, generating a dangerous case, and sending an alarm instruction to a smoke alarm.
As shown in fig. 3, when the acceleration rate of the humidity value is greater than the second threshold value, the step S41 of adjusting the first threshold value to the third threshold value and then continuing to detect the smoke concentration value specifically includes:
step S411, when the acceleration rate of the humidity value is larger than a second threshold value, adjusting the first threshold value to a third threshold value;
step S412, continuously detecting the smoke concentration value;
step S413, when the smoke concentration value is greater than a third threshold, sending an alarm instruction to the smoke alarm, and when the smoke concentration value is less than the third threshold, continuing to detect the smoke concentration value.
In order to solve false alarm caused by water vapor, a humidity sensor is added in the smoke alarm, when the detected smoke concentration value reaches a first threshold value of an alarm point, the detection of the humidity value is accelerated, if the detected humidity value is rapidly increased and is greater than a second threshold value, the false alarm caused by the water vapor is judged, at the moment, the alarm is not triggered temporarily, the first threshold value is adjusted to be a third threshold value, the third threshold value is a smoke concentration value preset when the smoke alarm leaves a factory or set by a user according to the local environment, generally, a manufacturer presets the smoke alarm when the smoke alarm leaves the factory, the smoke concentration value is continuously detected, when the smoke concentration value is greater than the third threshold value, no matter whether the smoke concentration value is caused by the water vapor, an alarm instruction is sent to the smoke alarm, the user needs to be prompted when the water vapor concentration is too high, and the user takes corresponding protective measures in advance, and when the smoke concentration value is smaller than a third threshold value, continuously detecting the smoke concentration value.
