Background
The automatic induction door technology in the current market is mainly in a microwave induction mode and an infrared induction mode, wherein the infrared induction mode is divided into a passive induction mode and an active induction mode. The microwave detector detects whether a moving target exists in a defense distribution area by means of the microwave Doppler effect, the Doppler effect learns that the frequency of the reflected wave generated by a stationary object is not changed when the fixed-frequency microwave emitted by the fixedly-installed microwave detector is subjected to the fixed-frequency microwave, the Doppler frequency shift will occur when the reflected wave generated by a moving object is subjected to the fixed-frequency microwave, the change of the frequency is similar to the calculation of the relative speed, and the microwave detector has the defects that the stationary object cannot be detected, and the microwave radiation has certain harm to a human body.

Also his disadvantage is that only dynamic persons can be detected, and articles cannot be detected.
The active infrared detection module is divided into a bijection type and a reflection type. The correlation signal is strong but needs to be installed separately. The reflection type utilizes the principle of diffuse reflection, and the infrared reflection and the infrared reception can be completed on the same panel. However, infrared rays exist in natural light, all objects with the temperature higher than 0 ℃ can radiate the infrared rays, and the intensity of the infrared receiving signals can be influenced by the intensity of external environment illumination. In order to reduce the influence of this, background color recognition is often used in the market, and when a change is not detected within a certain time, the change is detected as a reference to distinguish whether or not a human approaches, but still static detection cannot be realized.

It means that the current mode is the mode A, and the detection area is the 7 th detection area with 9 areas working simultaneously.
2) When a person walks to the detection area and does not open the door, the indicating lamp still displays green, the infrared touch switch is touched at the moment, the indicating lamp turns red, and the automatic door is opened. After the time is timed for 1 minute and 55 seconds, the indicator light changes to a red light and flashes, which indicates that the door is about to be closed. At this time, an infrared touch switch is touched, the red light is normally on, the door is kept open, and the time is counted again. Waiting for 2 minutes again, the indicator light undergoes a transition from a red light being constantly on, a red light flashing, a green light being constantly on, and the automatic door is closed.

2. Test mode B detects the automatic door sensing condition of zone 7.
The theoretical working condition is as follows: only the infrared induction state is detected, a person or an object enters a detection area, the door is opened, the door is closed after the set time, and the default time is 5 s. In the door closing delay process, if a person triggers a door opening condition, timing is performed again, and the door closing time is adjustable.

Pressing the view mode button, when the pilot lamp goes out, then green light scintillation 2 times, red light scintillation 7 times, scintillation 2 times again behind 1s, red light scintillation 7 times, three cycles totally. It means that the current mode is the mode B, and the detection area is the 7 th detection area in which 9 areas simultaneously operate.
2) People move towards the door, the indicator light is changed into a red light and is normally on within the range of about 1m in front of the door, and the door is opened. This indicates that the infrared sensor has detected the entry of a person into the examination zone. At this time, the door is closed after the time when the lamp is turned backward by about 0.2m and the indicator lamp turns to red light to flash, which indicates that no person is detected to enter the detection area and the time is 5s from the time when the red light starts to flash.
3) When the door is closed, a person approaches the infrared touch switch from the side surface of the door, the infrared touch switch is touched, the automatic door does not respond, and the indicator light is still green to indicate that the infrared touch switch does not work.
4) When the door is closed, a person enters the detection area along with the door, which means that the indicator light is changed into a red light and is normally on, and the door is opened. The indication angle adjusting function plays a role, namely, the anti-pinch function is realized.
4) A paper box with the height of about 12cm is pushed to the position right below the front of the door and close to the door, the door is opened, the door is still kept in an opened state after being observed for a period of time, and the indicator light is still red and normally on, so that the static detection function can be realized.
The experimental results are as follows: the method conforms to the theoretical working condition and the design purpose.
3. Test mode C detects an automatic door sensing condition of zone 7.
The theoretical working condition is as follows: the infrared induction and the infrared touch switch work simultaneously. The infrared sensing function is started after the infrared touch switch is triggered, people or objects enter a detection area within 2 minutes, door opening can be conducted, the door opening duration is 2 minutes, people or objects enter the detection area during the door opening period, the door opening time is counted again, if the time exceeds 2 minutes, no people or objects enter the detection area, the door is closed, the infrared monitoring sensing function is closed, and the mode is ended.
The testing steps are as follows:
1) and (5) adjusting the mode by the infrared remote controller, and hearing the beeper for beeping, so that the adjustment is successful. Pressing the view mode button, when the pilot lamp goes out, then green light scintillation 3 times, red light scintillation 7 times, scintillation 3 times again behind 1s, red light scintillation 7 times, three cycles totally. It means that the current mode is mode C and the detection area is the 7 th detection area where 9 areas are simultaneously operated.
2) When people walk to the door and do not open the door, the indicator lamp still displays green, at the moment, the infrared touch switch is touched, and after a beeper which hears a tick sounds, the indicator lamp changes into a red light and slowly flickers, which indicates that the infrared induction function is started and waits for triggering. After walking to the detection zone again, the pilot lamp becomes red, and the door is opened. After leaving the detection zone, the pilot lamp becomes red light and twinkles fast, closes the door after 5s from the time of red light beginning scintillation.
3) And the door is opened when the door enters the infrared detection area again within 2 minutes (when the red light flickers), and the indicating lamp is changed into the red light and is normally on. Leave the detection zone, the pilot lamp becomes quick red light scintillation, and 5s back door is closed, and the pilot lamp becomes red light and slowly twinkles. And if no person enters the detection area within 2 minutes and touches the infrared touch switch, the indicator light turns into a green light and is normally on, and the infrared sensing function is turned off. And the detection area is entered again, and the door is not opened.
The experimental results are as follows: the method conforms to the theoretical working condition and the design purpose.
4. The division of the detection area, under the condition of mode B or mode C, the infrared induction function is started, the detection area 7 enters the detection area from far to near, stops when just triggering the door opening, and is the far range of the detection area. The change detection area is 1, at which time the inspection range is reduced and the red light also starts to blink, and the door is then closed. And the design requirements are met. In this way, comparing the left and right areas of the region 7 and the region 1 to the left and right, the difference between the other detection regions is compared, and the region division design is satisfied.
In conclusion, the theoretical design result is consistent with the actual result, which illustrates the feasibility of the infrared induction automatic door control device and method provided by the invention.

5) setting a required working mode, an infrared detection area, a door opening threshold value, a door closing threshold value and door closing delay time through an infrared remote controller, and checking a current working mode and the detection area;
6) the singlechip judges the current working mode, detection area, controls the infrared transmitting circuit to open/close, determines the working state of the indicator light, and determines the opening condition and the closing condition of the automatic door, for example, the working mode is that only the detection of the existence of people or objects enters an infrared detection area, when the detection of the infrared touch switch is not detected, and the detection area is the infrared detection area corresponding to the infrared receiving tubes n and m: and the single chip microcomputer controls the opening of the infrared transmitting tube circuit, and if a person appears in the nth or m detection area, the values detected by the infrared sensor are value _ n _ new and value _ m _ new, and the door is opened when the value _ n _ new is greater than the value _ n + opening threshold value or the value _ m _ new is greater than the value _ m + opening threshold value. When value _ n _ new < value _ n + close threshold and value _ m _ new < value _ m + close threshold, closing the door;
7) when no person or object enters the detection area in the door closing process, the door is opened, then closed and opened again, and the door is opened and closed repeatedly in such a way, because the opening threshold value is too close to the closing threshold value, the opening threshold value can be increased;
8) when the default detection depth does not meet the user requirement, the starting threshold value can be increased to reduce the detection depth, and the detection threshold value is reduced to increase the detection depth;
9) when a person enters the detection area and opens the door, and the person leaves, the default time delay ts is closed again, and the delay time can be increased or reduced by the remote controller for the automatic door to meet different requirements;
10) when the current working state is uncertain, the infrared remote controller is provided with a button for checking the current mode, the m-th working mode is represented by flashing the green light for m times, and the n-th detection area is represented by flashing the red light for n times.
