Embodiment 1

[0040] An embodiment of the present invention provides a do-not-disturb control method for a smoke alarm at night, such as figure 1 As shown, the method includes:

[0041] Step 100, detecting the voltage signal of the ambient light where the smoke alarm is located;

[0042] Step 200, the MCU reads the voltage signal at intervals;

[0043] Step 300 , the MCU controls whether the smoke alarm is switched to the do-not-disturb state at night according to the variation range of the read voltage signal.

[0044] The principle of the above method is: detect the voltage signal of the ambient light where the smoke alarm is located; the MCU reads the voltage signal at intervals; and the MCU controls whether the smoke alarm is switched to the do-not-disturb state at night according to the variation range of the read voltage signal.

[0045] In this embodiment, since the voltage signal of the ambient light where the smoke alarm is located can reflect the light of the environment where t...

Embodiment 2

[0047] The embodiment of the present invention provides a do-not-disturb control method for a smoke alarm at night, on the basis of the first embodiment, as figure 2 As shown, step 300 specifically includes the following steps:

[0048] Step 301, judging whether the variation range of the read voltage signal changes from the set daytime voltage range to the set nighttime voltage range, and if so, execute step 302;

[0049] Step 302, shorten the interval and continue to read the voltage signal;

[0050] Step 303, judging whether the voltage signals read multiple times consecutively after shortening the interval are all within the set nighttime voltage range, and if so, execute step 304;

[0051] Step 304, the MCU controls the smoke alarm to switch to the do-not-disturb state at night.

[0052]In this embodiment, if the change range of the read voltage signal changes from the set daytime voltage range to the set nighttime voltage range, the time may have changed from daytime ...

Embodiment 3

[0058] The embodiment of the present invention provides a do-not-disturb control method for a smoke alarm at night, on the basis of the second embodiment, as image 3 As shown, after step 304, the method also includes:

[0059] Step 305, judging whether the time that the smoke alarm is in the do-not-disturb state at night exceeds the set night time: if so, execute step 306;

[0060] Step 306, the MCU controls the smoke alarm to exit the do-not-disturb state at night;

[0061] Step 307, judging whether the variation range of the voltage signal read by the MCU is continuously within the set nighttime voltage range: if yes, execute step 308;

[0062] Step 308 , the MCU controls the smoke alarm not to switch to the do-not-disturb state at night.

[0063] In this embodiment, in order to prevent the alarm from being installed in a dark room and being in the do-not-disturb state at night for a long time and unable to work normally, timeout processing is added. The installation env...

Abstract

The invention is applicable to the technical field of smoke alarms, and provides a do-not-disturb control method at night, a circuit and a smoke alarm. The method includes detecting the voltage signal of the ambient light where the smoke alarm is located; the MCU reads the voltage at intervals. signal; the MCU controls whether the smoke alarm is switched to the do-not-disturb state at night according to the variation range of the voltage signal read. Since the voltage signal of the ambient light where the smoke alarm is located can reflect the light of the environment where the smoke alarm is located, according to the range of the voltage signal read, it can be determined whether it is nighttime, and then whether to switch the smoke alarm to nighttime Do-not-disturb state, when the smoke alarm is switched to the night-time do-not-disturb state, it avoids the frequent flashing of the LED lights of the smoke alarm at night, which affects people's normal rest at night.

Description

technical field [0001] The invention belongs to the technical field of smoke alarms, in particular to a do-not-disturb control method at night, a circuit and a smoke alarm. Background technique [0002] In today's society, with the continuous improvement of people's awareness of fire protection, more and more public places and individual residences have begun to install smoke alarms (also known as fire smoke alarms, smoke sensors, smoke sensors, etc.). Smoke alarms have practical significance for preventing family fires and reducing fire losses. However, the smoke alarms in the prior art usually have a shortcoming, that is, the LED lights of the smoke alarms will flicker periodically, or when the smoke alarms break down, the smoke alarms will immediately issue a fault warning. When people are resting, LED lights will flash periodically and fault warnings will affect people's normal rest. [0003] Therefore, there is a need for a technical solution that can solve the above-...
