Specifically, as shown in fig. 1, the present embodiment further includes an external photosensor 41, a light intensity comparator 42 electrically connected to the external photosensor 41, and a first a/D converter 43 electrically connected to the light intensity comparator 42. The external photosensor 41 converts the sensed light intensity signal into a voltage signal and inputs the voltage signal to the light intensity comparator 42. The light intensity comparator 42 compares the voltage signal inputted from the external photosensitive sensor 41 with the photosensitive reference voltage 40, and inputs the comparison result to the first a/D converter 43 for digital-to-analog signal conversion.

Specifically, as shown in fig. 1, the present embodiment further includes a wind speed sensor 51, a wind speed comparator 52 electrically connected to the wind speed sensor 51, and a second a/D converter 53 electrically connected to the wind speed comparator 52. The wind speed sensor 51 converts the sensed wind speed signal into a voltage signal and inputs the voltage signal to the wind speed comparator 52. The wind speed comparator 52 compares the voltage signal inputted from the wind speed sensor 51 with the wind speed reference voltage 50, and inputs the comparison result to the second a/D converter 53 for digital-to-analog signal conversion.

Specifically, as shown in fig. 1, the present embodiment further includes a three-input or gate selector 60, the output end of the first a/D converter 43, the output end of the second a/D converter 53 and the output end of the single chip microcomputer 30 are all connected to the input end of the three-input or gate selector 60, and the output end of the three-input or gate selector 60 is electrically connected to the security window motor 80.

Specifically, as shown in fig. 1, a manual button 70 is connected in series between the output terminal of the three-input or gate selector 60 and the security window motor 80, and the manual button 70 is used to directly cut off the electrical control of the security window motor 80. When the manual button 70 is open circuit control, the security window motor 80 is not electrically controlled. At this time, the security window can be manually unfolded or manually folded.

In the present embodiment, as shown in fig. 2, the indoor sensing device 10 is installed indoors inside the gate, the outdoor sensing device 20 is installed outdoors outside the gate, and since only one door is separated between the indoor sensing device 10 and the outdoor sensing device 20, the distance between the indoor sensing device 10 and the outdoor sensing device 20 should be smaller than the physical width of the human body, that is, in the present embodiment (including the second embodiment below), the case that the human body is jammed between the indoor sensing device 10 and the outdoor sensing device 20 so that neither the indoor sensing device 10 nor the outdoor sensing device 20 senses the human body is not considered. When someone goes in and out of the door, only three situations exist, namely, the indoor sensing device 10 senses the person but the outdoor sensing device 20 does not sense the person, the indoor sensing device 10 does not sense the person but the outdoor sensing device 20 senses the person, and the indoor sensing device 10 and the outdoor sensing device 20 sense the person.

In the present embodiment, the external light sensor 41 and the wind speed sensor 51 can be fixedly installed at a position outside the window or on the balcony, and the present embodiment is not limited to a specific installation position, but it should be understood that the external light sensor 41 and the wind speed sensor 51 are installed outdoors to sense the light and the wind speed of the external environment.

Example two

The embodiment discloses a method for starting an anti-theft window, which is applied to an anti-theft window system in the first embodiment, and specifically comprises the following steps as shown in fig. 3:

step S100: the indoor sensing device 10 and the outdoor sensing device 20 both sense the door entrance and exit movement, and the single chip microcomputer 30 calculates the number of people in the room, and the single chip microcomputer 30 outputs a control level according to the calculation result.

The external photosensor 41 senses the intensity of illumination, and the light intensity comparator 42 determines whether the light intensity is at night, and the comparison result determined by the light intensity comparator 42 is subjected to digital-to-analog conversion by the first a/D converter 43 and then outputs a control level.

The wind speed sensor 51 senses the wind speed intensity, and the wind speed comparator 52 determines whether the wind speed is too high, and the comparison result determined by the wind speed comparator 52 is subjected to digital-to-analog conversion by the second a/D converter 53 and then outputs a control level.

The control voltage average of the above three outputs is used to control the activation of the burglary-resisting window motor 80.

Step S200: when the output level of the single chip microcomputer 30, the output level of the first a/D converter 43 and the output level of the second a/D converter 53 all output a low level, the three-input or gate comparator outputs a low level, and at this time, the security window motor 80 stops starting;

when at least one of the output level of the single chip microcomputer 30, the output level of the first a/D converter 43, and the output level of the second a/D converter 53 outputs a high level, the three-input or gate comparator outputs a high level, and proceeds to step S300;

step S300: the three input or gate comparator outputs a high level.

When the manual button 70 is closed, the security window motor 80 is started; that is, the burglary-resisting window motor 80 is controlled by the output level of the three-input or door comparator output end to start.

When the manual button 70 is turned off, the security window motor 80 is not electrically controlled; that is, the security window is not controlled by the security window motor 80, and can be directly controlled by the user manually, and can not be automatically controlled after being controlled manually.

Further, in step S100, when the indoor infrared receiver 12/outdoor infrared receiver 22 receives the infrared light beam, the processing result of the indoor infrared processor 13/outdoor infrared receiver 22 is that the output terminal outputs a high level. When the indoor infrared receiver 12/outdoor infrared receiver 22 does not receive the infrared light beam, the processing result of the indoor infrared processor 13/outdoor infrared receiver 22 is that the output end outputs a low level. As shown in fig. 4 and 5, the process of calculating the number of people indoors by the single chip microcomputer 30 further includes the following sub-steps:

substep S110: when no person enters or exits, the output ends of the indoor infrared processor 13 and the outdoor infrared receiver 22 keep outputting high level/high level, and the number of persons in the room keeps unchanged. That is, the output levels of the output Q1 of the indoor infrared processor 13 and the output Q2 of the outdoor infrared processor 23 are Q1Q2=11 (it should be understood that "1" here represents a high level recognizable by the single chip microcomputer 30 and "0" represents a low level recognizable by the single chip microcomputer 30 for the convenience of description of fig. 4-5, and thus the simplified diagram of the judgment of the number of persons in the room of fig. 4-5 is shown in fig. 6).

When the single chip microcomputer 30 judges that the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 is jumped to output the low level/high level, that is, when the output levels of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 are Q1Q2=01, it proceeds to substep S120.

When the single chip microcomputer 30 determines that the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 is jumped to output the high level/low level, that is, when the output levels of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 are Q1Q2=10, the substep S130 is performed;

substep S120: the single chip microcomputer 30 proceeds to determine whether to jump to the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 to output a low level/low level, that is, proceeds to determine whether the output level conditions of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 jump to Q1Q2= 00.

If yes, go to substep S121;

and when the judgment result is negative, the indoor people counting is kept unchanged.

Substep S121: the single chip microcomputer 30 proceeds to determine whether to jump to the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 to output the high level/low level next, that is, proceeds to determine whether the output level conditions of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 jump to Q1Q2= 10.

If yes, go to substep S122;

and when the judgment result is negative, the indoor people counting is kept unchanged.

Substep S122: the single chip microcomputer 30 proceeds to determine whether to jump to the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 to output a high level/high level, that is, proceeds to determine whether the output level conditions of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 jump to Q1Q2= 11.

When the judgment result is yes, adding one to the number of the indoor people, and returning to the substep S110 to continue judging;

and when the judgment result is negative, the indoor people counting is kept unchanged.

Substep S130: the single chip microcomputer 30 proceeds to determine whether to jump to the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 to output a low level/low level, that is, proceeds to determine whether the output level conditions of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 jump to Q1Q2= 00.

If yes, go to substep S131;

and when the judgment result is negative, the indoor people counting is kept unchanged.

Substep S131: the single chip microcomputer 30 proceeds to determine whether to jump to the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 to output the low level/high level next, that is, proceeds to determine whether the output level conditions of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 jump to Q1Q2= 01.

If yes, go to substep S132;

and when the judgment result is negative, the indoor people counting is kept unchanged.

Substep S132: the single chip microcomputer 30 proceeds to determine whether to jump to the output terminal of the indoor infrared processor 13/outdoor infrared receiver 22 to output a high level/high level, that is, proceeds to determine whether the output level conditions of the output terminal Q1 of the indoor infrared processor 13 and the output terminal Q2 of the outdoor infrared processor 23 jump to Q1Q2= 11.

When the judgment result is yes, the number of the indoor people is reduced by one, and the substep S133 is carried out;

and when the judgment result is negative, the indoor people counting is kept unchanged.

Substep S133: the single chip microcomputer 30 judges whether the number of the indoor people is zero or not;

when the judgment result is yes, the single chip microcomputer 30 outputs a high level;

when the judgment result is negative, the process returns to the substep S110 to continue the judgment.

Specifically, in step S100, the determination of whether the light intensity comparator 42 is at night specifically includes the following steps:

the external photosensor 41 converts the intensity of the sensed illumination into a voltage signal, inputs the voltage signal into the light intensity comparator 42 to be compared with the light intensity base voltage, and the light intensity comparator 42 inputs the comparison result into the first a/D converter 43 to perform digital-to-analog conversion, and then the first a/D converter 43 outputs high and low levels.

When the voltage signal converted by the illumination intensity is smaller than the light intensity reference voltage, the output end of the first a/D converter 43 outputs a high level;

when the voltage signal converted by the illumination intensity is greater than the light intensity reference voltage, the output terminal of the first a/D converter 43 outputs a low level.

Specifically, in step S100, the step of judging whether the wind speed is too high by the wind speed comparator 52 specifically includes the following steps:

the wind speed sensor 51 converts the sensed wind speed strength into a voltage signal, inputs the voltage signal into the wind speed comparator 52 to be compared with the wind speed reference voltage 50, and the wind speed comparator 52 inputs the comparison result into the second a/D converter 53 to perform digital-to-analog conversion, and then outputs a high level and a low level through the second a/D converter 53.

When the voltage signal converted by the wind speed intensity is less than the wind speed reference voltage 50, the output end of the second a/D converter 53 outputs a low level;

when the voltage signal converted by the wind speed intensity is greater than the wind speed reference voltage 50, the output terminal of the second a/D converter 53 outputs a high level.

The above embodiment can automatically calculate the number of people in a room, and automatically open the motor 80 of the security window when the number of people in the room is zero, so as to open the security window and protect the room.

The embodiment can automatically open the security window motor 80 at night, so that the security window can be opened, and indoor protection can be realized at night.

The above embodiment can automatically open the security window motor 80 in a windy weather, thereby opening the security window.
