Example one :

The following describes a method for confirming the fire alarm of a smoke detector provided in Embodiment 1 of the present application. Please refer to FIG. 1. The method for confirming a fire alarm of the smoke detector in Embodiment 1 of the present application includes:

Step S101: When the fire alarm occurrence information is detected, obtain the temperature value collected by the temperature sensor, and determine whether the temperature value is higher than a preset fire alarm temperature;

The smoke detector can detect the smoke concentration through the smoke sensor, and if the smoke concentration meets the requirements, the fire alarm occurrence information is generated.

The smoke sensor includes optical signal transmitter, optical signal receiver and optical labyrinth. The optical signal transmitter can send out optical signals, and the optical path of the optical signal is processed through the optical labyrinth. Under normal circumstances, the optical signal receiver cannot Receive or receive a very weak optical signal, resulting in a very small current, but in the case of smoke, the optical signal receiver can receive a stronger optical signal, resulting in a larger current.

By analyzing and processing the current of the optical signal receiver, the smoke density entering the optical labyrinth can be judged at this time, so as to judge the fire alarm.

However, the smoke detector may cause false alarms due to interference factors such as dust, kitchen fumes, water vapor, and micro mosquitoes. Therefore, when the fire alarm information is detected, in addition to communication methods such as telephone, SMS and APP information, the direct responsible person ( For example, the owner can not only push the fire alarm information, but also make a second judgment based on the temperature value collected by the temperature sensor, and judge whether a fire has occurred at the alarm site according to whether the temperature value is higher than the preset fire alarm temperature.

Step S102: When the temperature value is higher than the preset fire alarm temperature, send a fire alarm message to the fire alarm processing department.

The preset fire alarm temperature can be set according to the actual situation. For example, the ambient temperature is usually lower than 40 degrees Celsius. Even in the kitchen and other environments, the temperature of the oil smoke is generally not higher than 100 degrees Celsius. Therefore, the preset fire alarm temperature can be set to 100 Degrees Celsius.

When the temperature value is higher than the preset fire alarm temperature, it indicates that there is a fire at the scene of the alarm. At this time, the alarm information is automatically sent to the fire alarm processing department to prompt the alarm, so that the fire alarm processing department promptly triggers the fire extinguishing personnel to deal with it, avoiding the expansion of the fire and reducing the fire Loss of life and property.

The fire alarm information may include the address of the alarm scene, in addition, it may also include a picture of the alarm scene, so that the fire alarm processing department can make a fire alarm judgment based on the picture.

Further, when the fire alarm occurrence information is detected, acquiring the temperature value collected by the temperature sensor and determining whether the temperature value is higher than a preset fire alarm temperature specifically includes:

A1. When the fire alarm occurrence information is detected, obtain the temperature value collected by the temperature sensor, calculate the rate of change of the temperature value, and obtain the temperature rise compensation coefficient corresponding to the rate of change;

Because the temperature sensor is installed inside the smoke detector, the temperature transfer takes time, and the temperature sensor itself has a hysteresis of temperature change. When the ambient temperature rises rapidly, the temperature value detected by the temperature sensor is consistent with the actual ambient temperature value There will be differences.

Therefore, when the fire alarm occurrence information is detected, the rate of change of the temperature value can be calculated according to the plurality of temperature values collected by the temperature sensor, thereby obtaining the temperature rise compensation coefficient corresponding to the rate of change.

The temperature rise compensation coefficients corresponding to different change rates can be obtained by analyzing the temperature sensor characteristics and experimental data in advance.

A2. Multiply the preset fire alarm temperature by the temperature rise compensation coefficient to obtain a new preset fire alarm temperature, and determine whether the temperature value is higher than the preset fire alarm temperature.

After obtaining the temperature rise compensation coefficient corresponding to the change rate, the preset fire alarm temperature is multiplied by the temperature rise compensation coefficient to obtain a new preset fire alarm temperature.

The temperature rise compensation is performed by the temperature rise compensation coefficient. The greater the rate of change, the smaller the temperature rise compensation coefficient. The temperature rise compensation by the temperature rise compensation coefficient can reduce the hysteresis of temperature detection and improve the speed and accuracy of the fire alarm.

Further, the method further includes:

B1. When the fire alarm occurrence information is detected, the temperature collection cycle is changed from the normal collection cycle to the fire alarm collection cycle, and the fire alarm collection cycle is less than the normal collection cycle.

When the fire alarm occurrence information is detected, the temperature collection cycle can be changed from the normal collection cycle to the fire alarm collection cycle. The normal collection cycle is the temperature collection cycle when no fire alarm occurrence information is detected. The fire alarm collection cycle is less than the normal collection cycle, so that the Continuously and quickly collect temperature values per unit time, increase the number of collected temperature values, and improve the speed and accuracy of fire alarms.

Further, the method further includes:

C1. When the fire alarm occurrence information is not detected, determine whether the difference between the collected temperature value and the normal temperature value is greater than or equal to a preset error adjustment value;

When the smoke detector is in a state where no fire alarm occurrence information is detected, the normal automatic compensation of the preset fire alarm temperature can also be performed according to the change of the ambient temperature.

According to whether the difference between the temperature value collected by the temperature sensor and the normal temperature value is greater than or equal to the preset error adjustment value, it is determined whether to perform the normal automatic compensation of the preset fire alarm temperature.

C2. When the difference between the collected temperature value and the normal temperature value is greater than or equal to the preset error adjustment value, use the collected temperature value as a new normal temperature value and set the preset The fire alarm temperature is added to the difference to obtain a new preset fire alarm temperature.

When the difference between the collected temperature value and the normal temperature value is greater than or equal to the preset error adjustment value, it indicates that the ambient temperature has changed a lot (for example, the kitchen use state and the non-use state have a larger change in ambient temperature), At this time, the normal automatic compensation needs to be performed according to the actual ambient temperature, the collected temperature is used as the new normal temperature value, and the preset fire alarm temperature is added to the difference to obtain the new fire alarm temperature.

The collected temperature value can be the temperature value collected in real time or the average value of the temperature value collected in a long period of time (for example, one hour). The specific settings can be set according to actual needs.

Further, before the determining whether the difference between the collected temperature value and the normal temperature value is greater than or equal to a preset error adjustment value, the method further includes:

D1. Determine whether the collected temperature value is within a preset interval;

The temperature value collected by the temperature sensor can be processed through a filtering algorithm to remove noise and invalid data, and it can be judged whether the collected temperature value is within a preset interval.

D2. When the collected temperature value is not within a preset interval, remove the collected temperature value.

When the collected temperature value is not within the preset interval, that is, it exceeds the actual possible temperature range, it indicates that the temperature value is noise data, and the temperature value can be eliminated.

Further, when the collected temperature value is not within a preset interval, after excluding the collected temperature value, the method further includes:

E1. Calculate the standard deviation of the temperature values collected within the preset duration, and determine whether the standard deviation is greater than or equal to the preset standard deviation threshold;

In addition, it is also possible to calculate the standard deviation of the temperature values collected within the preset duration, and determine whether the standard deviation is greater than or equal to the preset standard deviation threshold.

E2. When the standard deviation is greater than or equal to a preset standard deviation threshold, remove the temperature value collected within the preset duration.

When the standard deviation is greater than or equal to the preset standard deviation threshold, it means that the data in this segment fluctuates greatly and the data is unstable. You can treat this segment of data as invalid data and remove the invalid data to collect again.

In addition, when the collected temperature value is obviously abnormal, for example, the deviation of the collected temperature value from the last collected temperature value is greater than the preset deviation threshold, or the collected temperature value is not within the preset interval, etc. In some cases, the temperature value collection cycle can be reduced by means of differential levels, that is, the greater the data abnormality, the smaller the collection cycle, thereby increasing the overall number of collected temperature values, increasing data calculation processing techniques, and improving the accuracy of the processing results.

Eliminating the noise data and invalid data through the filtering algorithm can improve the accuracy of the processing results in the subsequent temperature value processing and judgment process, and avoid interference from the noise data and invalid data.

In the method for confirming the fire alarm of the smoke detector provided in the first embodiment, after detecting the fire alarm occurrence information according to the detection data of the smoke sensor, the temperature value collected by the temperature sensor is obtained, and it is judged whether the temperature value is higher than the preset fire alarm temperature. Fire or smoke alarm false alarm, when the temperature value is not higher than the preset fire alarm temperature, it means that the alarm scene may be false alarm due to interference factors such as dust, kitchen fumes, water vapor and micro mosquitoes, when the temperature value is higher than the preset fire alarm temperature When it indicates that a fire has occurred at the alarm site, the fire alarm information is automatically sent to the fire alarm processing department, without the need for relevant personnel to confirm the fire situation at the alarm site, the fire alarm processing department can be alerted in time, which solves the existing fire alarm scheme when the smoke When the detector is warning, in order to avoid the false alarm phenomenon of the smoke detector, it is necessary for the relevant personnel to confirm the fire situation at the alarm site. It may take a long time to confirm the fire alarm situation, and the fire alarm processing department cannot be notified in time, which may lead to the expansion of the fire The problem of causing greater loss of life and property.

When the fire alarm occurrence information is detected, the rate of change of the temperature value can be calculated to obtain the temperature rise compensation coefficient corresponding to the change rate, the preset fire alarm temperature can be compensated by the temperature rise compensation coefficient, and the temperature collection period can also be changed from The normal collection cycle is changed to a fire alarm collection cycle to increase the collection frequency, thereby increasing the speed and accuracy of the fire alarm.

When the fire alarm occurrence information is not detected, the preset fire alarm temperature can be adjusted according to the change of the normal temperature value. For example, if the ambient temperature rises, the preset fire alarm temperature should increase accordingly, thereby improving the accuracy of the fire alarm.

For the collected temperature values, data can be cleaned by a filtering algorithm to remove noise data and invalid data to ensure the accuracy of subsequent processing and analysis of temperature values.

It should be understood that the size of the sequence numbers of the steps in the above embodiments does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
