[0029] like Figure 1 As shown, the fire alarm method comprises:

[0030] S101: Determine a first temperature value and a first humidity value in an environment when the gas-sensitive semiconductor smoke alarm device is powered on for the first time.

[0031] The first temperature value and the first humidity value may be obtained by temperature and humidity sensors pre-configured in the gas-sensitive semiconductor smoke alarm device.

[0032] In the embodiment of the present disclosure, when the first temperature value and the first humidity value in the environment are determined when the gas-sensitive semiconductor smoke alarm device is powered on for the first time, the temperature and humidity under the initial environmental state can be perceived, thereby providing reliable data support for subsequent fire alarms.

[0033] S102: Determine a first conductivity of a gas-sensitive semiconductor sensor according to a first temperature value and a first humidity value, and convert the first conductivity into a first voltage value, wherein the gas-sensitive semiconductor sensor is configured in a gas-sensitive semiconductor smoke alarm device.

[0038] S103: After the preheating of the gas-sensitive semiconductor smoke alarm device is completed, the second conductivity of the gas-sensitive semiconductor sensor is monitored, and the second conductivity is converted into a second voltage value.

[0039] In the embodiment of the present disclosure, the gas-sensitive semiconductor smoke alarm device can be based on a tin dioxide smoke sensor element for smoke alarm, and its preheating time can be between 30 seconds and 60 seconds. In the embodiment of the present disclosure, the gas-sensitive semiconductor smoke alarm device can also be based on any other possible smoke sensor, and the corresponding preheating time can also be adjusted accordingly, without limitation.

[0041] The second voltage value refers to a voltage value determined after converting the second conductivity by means of resistance voltage division.

[0042] In the disclosed embodiment, after the preheating of the gas-sensitive semiconductor smoke alarm device is completed, the second conductivity of the gas-sensitive semiconductor sensor is monitored and converted into a second voltage value, thereby achieving real-time monitoring of the concentration of combustible gas or smoke in the environment.

[0045] The third voltage value may refer to a voltage value determined after converting the third conductivity by means of resistance voltage division.

[0046] In the embodiment of the present disclosure, when the second voltage value is greater than the first voltage value, it indicates that a fire may have occurred. At this time, the gas-sensitive semiconductor smoke alarm device is powered off and then powered on again to monitor the third conductivity of the gas-sensitive semiconductor sensor and convert the third conductivity into a third voltage value, which can provide reliable data support for subsequent secondary confirmation of the fire.

[0047] S105: Determine a second temperature value and a second humidity value in the environment, determine a fourth conductivity of the gas-sensitive semiconductor sensor according to the second temperature value and the second humidity value, and convert the fourth conductivity into a fourth voltage value.

[0048] The second temperature value and the second humidity value refer to the real-time temperature value and the real-time humidity value monitored and obtained after the gas-sensitive semiconductor smoke alarm device is powered off and then powered on again when the second voltage value is greater than the first voltage value.

[0049] The fourth conductivity refers to the conductivity of the gas-sensitive semiconductor sensor determined based on the second temperature value and the second humidity value, and the fourth voltage value refers to the voltage value determined after converting the fourth conductivity by using a resistor voltage divider.

[0050] In the embodiment of the present disclosure, when the second temperature value and the second humidity value in the environment are determined, and the fourth conductivity of the gas-sensitive semiconductor sensor is determined based on the second temperature value and the second humidity value, and the fourth conductivity is converted into a fourth voltage value, real-time monitoring of the concentration of combustible gas or smoke can be achieved, thereby providing reliable reference information for subsequent fire alarms.

[0051] S106: Fire alarm is issued according to the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value.

[0052] In the embodiment of the present disclosure, when a fire alarm is issued based on the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value, the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value may be input into a pre-trained machine learning model to determine whether a fire has occurred so as to issue an alarm; or, a fire alarm may be issued based on the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value based on a method combining numbers and shapes, and there is no limitation to this.

[0053] In this embodiment, when the gas-sensitive semiconductor smoke alarm device is powered on for the first time, the first temperature value and the first humidity value in the environment are determined; according to the first temperature value and the first humidity value, the first conductivity of the gas-sensitive semiconductor sensor is determined, and the first conductivity is converted into a first voltage value, wherein the gas-sensitive semiconductor sensor is configured in the gas-sensitive semiconductor smoke alarm device; after the preheating of the gas-sensitive semiconductor smoke alarm device is completed, the second conductivity of the gas-sensitive semiconductor sensor is monitored, and the second conductivity is converted into a second voltage value; when the second voltage value is greater than the first voltage value, the gas-sensitive semiconductor smoke alarm device is controlled to be powered on again after being powered off, the third conductivity of the gas-sensitive semiconductor sensor is monitored, and the third conductivity is converted into a third voltage value; the second temperature value and the second humidity value in the environment are determined, and the fourth conductivity of the gas-sensitive semiconductor sensor is determined according to the second temperature value and the second humidity value, and the fourth conductivity is converted into a fourth voltage value; and a fire alarm is performed according to the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value. In this way, the accuracy of the fire alarm can be effectively improved at a relatively low cost.

[0054] Optionally, in some embodiments, when a fire alarm is issued based on the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value, and the fourth voltage value, the following steps may be performed: determining a comparison result between the first temperature value and the second temperature value; determining that no fire has occurred when the comparison result indicates that the first temperature value is greater than or equal to the second temperature value; and issuing a fire alarm based on the first voltage value, the second voltage value, the third voltage value, and the fourth voltage value when the comparison result indicates that the first temperature value is less than the second temperature value. Thus, a preliminary judgment on whether a fire has occurred may be made based on the comparison result between the first temperature value and the second temperature value.

[0055] It can be understood that when a fire occurs, the ambient temperature will rise accordingly. Therefore, in the embodiment of the present disclosure, the comparison result of the first temperature value and the second temperature value can be determined; when the comparison result indicates that the first temperature value is greater than or equal to the second temperature value, it is determined that no fire has occurred; when the comparison result indicates that the first temperature value is less than the second temperature value, a fire alarm is issued based on the first voltage value, the second voltage value, the third voltage value and the fourth voltage value.

[0056] Optionally, in some embodiments, when a fire alarm is issued based on a first voltage value, a second voltage value, a third voltage value and a fourth voltage value, a fire alarm may be issued when the first voltage value is greater than or equal to the fourth voltage value, if the second voltage value is greater than the first voltage value, and the third voltage value is greater than the first voltage value.

[0057] Optionally, in some embodiments, when a fire alarm is issued based on the first voltage value, the second voltage value, the third voltage value and the fourth voltage value, a fire alarm may also be issued when the first voltage value is less than the fourth voltage value, if the second voltage value is greater than the first voltage value, and the third voltage value is greater than the fourth voltage value.

[0058] Based on the above embodiments, the present disclosure can solve the false alarm problem by modifying the operating logic of the single-chip microcomputer without changing the module and function of the original product (gas-sensitive semiconductor smoke alarm device).

[0059] For example, the gas-sensitive material used in a gas-sensitive semiconductor sensor may be tin dioxide (SnO2), which has a low electrical conductivity in clean air. As the concentration (ppm) of combustible gas or smoke in the air increases, the electrical conductivity of the sensor also increases. At the same time, the resistance ratio of the sensor will also change due to different temperature and humidity conditions in the environment.

[0060] According to the above principle, when the gas-sensitive semiconductor smoke alarm device is powered on for the first time, the single-chip microcomputer records the environmental temperature and humidity data once, sets them as the first temperature value T1 and the first humidity value H1, records the initial conductivity σ1 of the sensor (i.e. the above first conductivity) according to the values ​​of T1 and H1, and converts the conductivity change into a voltage signal V1 (i.e. the above first voltage value) corresponding to the concentration by means of resistance voltage division, and sets the aerosol concentration alarm threshold (V1) accordingly, and at the same time, the device starts to preheat and prepare to receive changes in the external aerosol concentration.

[0061] The preheating time of the tin dioxide smoke sensor usually takes 30 seconds to 1 minute. After the preheating is completed, the microcontroller records the current sensor conductivity σ s1 (i.e. the second conductivity mentioned above), converted to V s1 (i.e. the second voltage value mentioned above); thereafter, when the smoke alarm device reaches the aerosol concentration alarm threshold (V1) for the first time, the device is powered off for 3 seconds and then powered on again, and the single chip records the current sensor conductivity σ s2 (i.e. the third conductivity mentioned above), converted to V s2(i.e. the third voltage value mentioned above); re-record the ambient temperature and humidity data once, set them as the second temperature value T2 and the second humidity value H2, record the current initial conductivity of the sensor as σ2 (i.e. the fourth conductivity mentioned above) according to the T2 and H2 values, and reset the aerosol concentration alarm threshold (V2) according to V2 (i.e. the fourth voltage value) converted by the single-chip microcomputer.

[0062] The process of re-powering is also the process of eliminating the influence of temperature and humidity on the measurement results. By comparing the changes of temperature and humidity twice, as well as the data of V1 and V2, it can be seen that the lower the humidity, the lower the temperature, and the lower the conductivity. In general, when a fire occurs, it should be accompanied by a temperature increase, that is, T2>T1, which means that the temperature increases in a short period of time. In addition, V s1 >V1 and V s2 >V 最大 (V 最大 is the maximum value of V1 and V2), it proves that the aerosol concentration (ppm) rises within a few seconds, eliminating the interference factor of dust. It can be determined that there is a gas leakage or electrical fire smoke has been generated, and there is a fire risk. When the above three conditions are met, it can be determined that an electrical fire has occurred.

[0063] For example, Figure 2 As shown, Figure 2 is a component diagram of the fire alarm method application device proposed in the embodiment of the present disclosure, wherein:

[0064] Component 1 is the LED indicator light; Component 2 is the physical dust screen;

[0065] Component 3 is the tin dioxide smoke sensor; Component 4 is the mounting base.

[0066] For example, Figure 3 As shown, Figure 3 It is a control flow chart of the fire alarm method proposed in the embodiment of the present disclosure. After power-on preheating, smoke passes through the physical dustproof net to reach the vicinity of the tin dioxide sensor, detects the change in smoke concentration, and the device alarms for the first time.

[0067] like Figure 2 As shown, after the LED indicator lights up, the microcontroller automatically powers off and powers on again after 3s.

[0068] After 3s of power on, according to Figure 3 The logic microcontroller shown performs automatic identification. If the identification result shows that there is a fire risk or an electrical fire has already occurred, the alarm will be sounded again and the preset mechanism in the fire alarm system will be triggered.

[0069] This method takes advantage of the fact that the gas-sensitive semiconductor smoke sensor needs to set an initial threshold value, eliminates the influence of temperature and humidity changes on the sensor conductivity, and improves reliability. Power is turned on again after three seconds of power failure, taking advantage of the fact that the gas-sensitive semiconductor smoke sensor needs to be preheated. According to the sensor's response recovery characteristic curve, the sensor takes about 6 seconds to recover the response characteristics from power failure, which extends the detection cycle of the smoke sensor, eliminates the short-term interference of smoke, broadens the confidence interval of the detection results, and further improves the reliability of the smoke sensor.

[0070] Figure 4 It is a structural schematic diagram of a fire alarm device proposed in one embodiment of the present disclosure.

[0077] The alarm module 406 is used to generate a fire alarm according to the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value.

[0078] Optionally, in some embodiments, the alarm module 406 is specifically configured to:

[0079] Determine a comparison result between the first temperature value and the second temperature value;

[0080] When the comparison result indicates that the first temperature value is greater than or equal to the second temperature value, determining that no fire has occurred;

[0081] When the comparison result indicates that the first temperature value is less than the second temperature value, a fire alarm is issued according to the first voltage value, the second voltage value, the third voltage value and the fourth voltage value.

[0082] Optionally, in some embodiments, the alarm module 406 is further configured to:

[0086] It should be noted that the aforementioned explanation of the fire alarm method is also applicable to the fire alarm device of this embodiment and will not be repeated here.

[0087] In this embodiment, when the gas-sensitive semiconductor smoke alarm device is powered on for the first time, the first temperature value and the first humidity value in the environment are determined; according to the first temperature value and the first humidity value, the first conductivity of the gas-sensitive semiconductor sensor is determined, and the first conductivity is converted into a first voltage value, wherein the gas-sensitive semiconductor sensor is configured in the gas-sensitive semiconductor smoke alarm device; after the preheating of the gas-sensitive semiconductor smoke alarm device is completed, the second conductivity of the gas-sensitive semiconductor sensor is monitored, and the second conductivity is converted into a second voltage value; when the second voltage value is greater than the first voltage value, the gas-sensitive semiconductor smoke alarm device is controlled to be powered on again after being powered off, the third conductivity of the gas-sensitive semiconductor sensor is monitored, and the third conductivity is converted into a third voltage value; the second temperature value and the second humidity value in the environment are determined, and the fourth conductivity of the gas-sensitive semiconductor sensor is determined according to the second temperature value and the second humidity value, and the fourth conductivity is converted into a fourth voltage value; and a fire alarm is performed according to the first temperature value, the second temperature value, the first voltage value, the second voltage value, the third voltage value and the fourth voltage value. In this way, the accuracy of the fire alarm can be effectively improved at a relatively low cost.
