[0002] Among various disasters, fire is one of the major threats to social development and public safety. Fire alarm systems play a crucial role in preventing and reducing fire hazards, and smoke alarms are an important component of these systems, primarily achieving fire prevention by monitoring smoke concentration. In existing smoke alarm methods, when a smoke detector determines a fire has occurred based on the detected smoke concentration, it triggers an audible and visual alarm. Simultaneously, other associated smoke detectors also trigger similar audible and visual alarms, resulting in locations with varying degrees of fire severity issuing alarm signals of the same level of danger. This leads to relatively low accuracy in existing smoke alarm methods. Summary of the Invention

Attached Figure Description
[0047] To more clearly illustrate the technical solutions of the embodiments of this application, the drawings used in the description of the embodiments of this application will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0048] Figure 1 This is a flowchart of the smoke alarm method provided in the embodiments of this application;
[0049] Figure 2 This is a structural diagram of a smoke alarm device provided in another embodiment of this application;
[0050] Figure 3 This is a structural diagram of an electronic device provided in another embodiment of this application. Detailed Implementation
[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0052] This application provides a smoke alarm method. See also... Figure 1 , Figure 1 This is a flowchart of the smoke alarm method provided in the embodiments of this application, such as... Figure 1 As shown, it includes the following steps:
[0053] Step 101: When the smoke concentration detected by the first smoke alarm reaches the preset smoke concentration, control the first smoke alarm to output the first alarm state. The first smoke alarm is the smoke alarm at the fire location in the fire monitoring area.
[0054] In an actual fire, the smoke detector located at the fire location will often detect the highest smoke concentration. Taking the smoke detector at the fire location as the first smoke detector, when the smoke concentration detected by the first smoke detector reaches the preset smoke concentration, it indicates that the fire is already quite serious. At this time, the first smoke detector is controlled to output the first alarm state to warn people. It should be noted that the first alarm state can be understood as the immediate escape state, and its volume is the maximum volume, and the alarm light can be a red light.
[0055] Step 102: When the first smoke alarm outputs a first alarm state, control N second smoke alarms to output a second alarm state, where N is an integer greater than or equal to 1, and the N second smoke alarms are other smoke alarms associated with the first smoke alarm within the fire monitoring area. The alarm volume of the first alarm state is greater than the alarm volume of the second alarm state, and the brightness of the alarm light in the first alarm state is greater than the brightness of the alarm light in the second alarm state.
[0056] After a fire occurs at a certain location within the fire monitoring area, other locations may also be at risk of being affected by the fire. However, the degree of danger may differ from that at the actual location of the fire. Therefore, when the first smoke detector at the fire location outputs a first alarm state, N second smoke detectors at other locations are controlled to output a second alarm state. It should be noted that the second alarm state can be understood as an indication state, with a volume lower than that of the first alarm state, and the alarm light can be green.
[0057] In the smoke alarm method of this application embodiment, by controlling the smoke alarm located at the fire location and other smoke alarms associated with it to output different alarm states within the fire monitoring area, the severity of the fire at different locations within the fire monitoring area can be distinguished. People at different locations can evacuate in an orderly manner based on the alarm states of different alarms, thereby improving the accuracy of the smoke alarm method.
[0058] Optionally, after controlling N second smoke detectors to output a second alarm state when the first smoke detector outputs a first alarm state, the method further includes:
[0059] The duration for which the smoke concentration detected by each of the M second smoke detectors reaches the preset smoke concentration is obtained respectively, wherein the M second smoke detectors are the smoke detectors adjacent to the first smoke detector among the N second smoke detectors;
[0060] The diffusion rate of the smoke detected by each of the M second smoke detectors is calculated based on the time it takes for the smoke concentration detected by each of the M second smoke detectors to reach the preset smoke concentration, and the distance between each of the M second smoke detectors and the first smoke detector.
[0061] The alarm status of the N second smoke detectors is updated based on the smoke diffusion rate detected by the M second smoke detectors.
[0062] In the smoke alarm method of this application embodiment, after the first smoke alarm at the fire location outputs a first alarm state and N second smoke alarms at other locations output a second alarm state, the smoke concentration of M second smoke alarms adjacent to the first smoke alarm among the N second smoke alarms is detected, and the time when these M second smoke alarms reach a preset smoke concentration is recorded.
[0063] Based on the time it takes for the smoke concentration detected by each of the M second smoke detectors to reach the preset smoke concentration, and the distance between each of the M second smoke detectors and the first smoke detector, the smoke diffusion rate of each of the M second smoke detectors is calculated. Since the smoke diffusion rates are different, it indicates that the degree of danger will also be different between other locations outside the fire location. Therefore, the alarm status of the N second smoke detectors is updated.
[0064] This method updates the alarm status of N second smoke detectors by measuring the smoke diffusion rate at different locations within the fire monitoring area to differentiate the degree of danger at different locations, thereby improving the accuracy of the smoke alarm method.
[0065] Optionally, updating the alarm status of the N second smoke detectors based on the smoke diffusion rate detected by the M second smoke detectors includes:
[0066] Control all second smoke alarms in the first smoke diffusion direction to output normal status. The first smoke diffusion direction is the direction from the first smoke alarm to the first type of smoke alarm. The first type of smoke alarm is the smoke alarm among the M second smoke alarms whose detected smoke diffusion speed is less than a first preset value.
[0067] All second smoke alarms in the second smoke diffusion direction are controlled to output a third alarm state. The second smoke diffusion direction is from the first smoke alarm to the second type of smoke alarm. The second type of smoke alarm is the smoke alarm among the M second smoke alarms whose detected smoke diffusion speed is greater than a first preset value and less than a second preset value. The alarm volume of the third alarm state is greater than the alarm volume of the second alarm state and less than the alarm volume of the first alarm state. The alarm light brightness of the third alarm state is greater than the alarm light brightness of the second alarm state and less than the alarm light brightness of the first alarm state.
[0068] The alarm status of all second smoke alarms in the third smoke diffusion direction is controlled to output a first alarm status. The third smoke diffusion direction is the direction from the first smoke alarm to the third type of smoke alarm. The third type of smoke alarm is the smoke alarm among the M second smoke alarms whose detected smoke diffusion speed is greater than a second preset value. The M second smoke alarms are at least one type of smoke alarm among the first type of smoke alarm, the second type of smoke alarm, and the third type of smoke alarm.
[0069] In the smoke alarm method of this application embodiment, the diffusion speed of smoke detected by M second smoke alarms is calculated. If the smoke diffusion speed of a certain second smoke alarm is less than a first preset value, all second smoke alarms in the diffusion direction of the first smoke alarm are controlled to output a normal state. If the smoke diffusion speed of a certain second smoke alarm is greater than the first preset value and less than the second preset value, all second smoke alarms in the diffusion direction of the first smoke alarm are controlled to output a third alarm state. If the smoke diffusion speed of a certain second smoke alarm is greater than the second preset value, all second smoke alarms in the diffusion direction of the first smoke alarm are controlled to output a first alarm state.
[0070] It should be noted that the aforementioned normal state means no alarm is issued; the third alarm state can be understood as the preparation to escape state, in which the alarm volume of the third alarm state is greater than the alarm volume of the second alarm state but less than the alarm volume of the first alarm state, and the alarm light can be yellow; the first alarm state can be understood as the immediate escape state, its volume is the maximum volume, and the alarm light can be red.
[0071] This method updates the alarm status of N second smoke detectors by measuring the smoke diffusion rate at different locations within the fire monitoring area to differentiate the degree of danger at different locations, thereby improving the accuracy of the smoke alarm method.
[0072] Optionally, the N second smoke detectors include a first target smoke detector and a second target smoke detector, wherein the first target smoke detector and the second target smoke detector are adjacent smoke detectors.
[0073] After updating the alarm status of the N second smoke detectors based on the smoke diffusion rate detected by the M second smoke detectors, the method further includes:
[0074] The first duration during which the smoke concentration detected by the first target smoke alarm reaches the preset smoke concentration and the second duration during which the smoke concentration detected by the second target smoke alarm reaches the preset smoke concentration are respectively obtained;
[0075] Calculate the difference between the first duration and the second duration;
[0076] Based on the difference between the first duration and the second duration, and the distance between the first target smoke alarm and the second target smoke alarm, the smoke diffusion rate from the first target smoke alarm to the second target smoke alarm is calculated.
[0077] Based on the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm, the alarm status of the second smoke alarm in the target smoke diffusion direction is determined, wherein the target smoke diffusion direction is the direction from the first target smoke alarm to the second target smoke alarm.
[0078] In the smoke alarm method of this application embodiment, after updating the alarm status of N second smoke alarms according to the smoke diffusion rate detected by M second smoke alarms adjacent to the first smoke alarm, the smoke diffusion rate at each point continues to be detected in real time. The diffusion rate is the smoke diffusion rate detected by any two adjacent smoke alarms among the N second smoke alarms.
[0079] For example, the first target smoke alarm and the second target smoke alarm are adjacent smoke alarms among N second smoke alarms. A first duration for the smoke concentration detected by the first target smoke alarm to reach a preset smoke concentration is obtained, and a second duration for the smoke concentration detected by the second target smoke alarm to reach the preset smoke concentration is obtained. The difference between the first and second durations, and the distance between the first and second target smoke alarms, are calculated to determine the smoke diffusion rate from the first target smoke alarm to the second target smoke alarm. Based on this smoke diffusion rate, the alarm status of all second smoke alarms in the direction from the first target smoke alarm to the second target smoke alarm is determined.
[0080] It should be noted that the smoke concentration detected by the first target smoke alarm is greater than that detected by the second target smoke alarm, therefore the smoke diffusion direction is from the first target smoke alarm to the second target smoke alarm.
[0081] This method calculates the smoke diffusion rate of any two adjacent smoke detectors among N second smoke detectors to determine the alarm status of the second smoke detectors in different smoke diffusion directions, thereby distinguishing the severity of fires at different locations and improving the accuracy of the smoke alarm method.
[0082] Optionally, determining the alarm status of the second smoke alarm in the target smoke diffusion direction based on the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm includes:
[0083] When the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm is less than a first preset value, the second smoke alarm in the target smoke diffusion direction is controlled to output a normal state.
[0084] When the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm is greater than a first preset value and less than a second preset value, the output of the third alarm state of the second smoke alarm in the target smoke diffusion direction is controlled.
[0085] When the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm is greater than a second preset value, the second smoke alarm in the target smoke diffusion direction is controlled to output a first alarm status.
[0086] In the smoke alarm method of this application embodiment, when the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm is less than a first preset value, all second smoke alarms in the smoke diffusion direction from the first target smoke alarm to the second target smoke alarm are controlled to output a normal state, that is, no alarm is issued; when the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm is greater than the first preset value and less than the second preset value, all second smoke alarms in the smoke diffusion direction from the first target smoke alarm to the second target smoke alarm are controlled to output a third alarm state, which can be understood as a preparation for escape state. At this time, the alarm volume of the third alarm state is greater than the alarm volume of the second alarm state and less than the alarm volume of the first alarm state, and the alarm light can be a yellow light; when the smoke diffusion speed from the first target smoke alarm to the second target smoke alarm is greater than the second preset value, all second smoke alarms in the smoke diffusion direction from the first target smoke alarm to the second target smoke alarm are controlled to output a first alarm state, which can be understood as an immediate escape state. Its volume is the maximum volume, and the alarm light can be a red light.
[0087] This method determines the alarm status of the second smoke detectors in different smoke diffusion directions based on the smoke diffusion speed of any adjacent smoke detectors among N second smoke detectors, thereby distinguishing the severity of fires in different locations and improving the accuracy of the smoke alarm method.
[0088] Based on the different smoke diffusion rates detected by all smoke detectors in various smoke diffusion directions, a smoke diffusion map of the fire detection area can be generated, so that the escape command center can direct the evacuation of personnel accordingly based on the smoke diffusion map.
[0089] See Figure 2 , Figure 2 This is a structural diagram of a smoke alarm device provided in another embodiment of this application, as shown below. Figure 2 The smoke alarm device 200 includes:
