All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Since the door can insulate a space and perform a theft prevention function, it is necessary to detect an open/close state of the door to determine whether the door is closed. The conventional detection method is a hall sensor, and specifically, a magnet is installed on one side of a door, and the hall sensor is installed on the other side of the door. When the magnet approaches the Hall sensor to reach the effective range, the Hall sensor can generate high and low voltage changes, so that an electric signal is formed and transmitted to a background detection system, and one-time opening and closing detection is completed.
However, the conventional detection method has the following technical problems: when the door is opened and closed, the door body may generate different amplitudes due to various conditions (for example, the user collides with the door body or the door body collides with the door lock), especially, the various amplitudes may affect the induction of the hall sensor, so that the hall sensor repeatedly obtains high and low voltage values of "on" and "off" in a short time, and further generates a false trigger signal, so that the background detection system misjudges the open and closed states of the door, and the detection accuracy is reduced.
In order to solve the above problem, a method for detecting opening and closing of a door provided in an embodiment of the present application will be described and explained in detail through the following specific embodiments.
Referring to fig. 1, a schematic flow chart of a method for detecting opening and closing of a door according to an embodiment of the present invention is shown.

Specifically, the hall sensor can be arranged on the door body, and can acquire the sensing signal of the door body through the hall sensor.
In one embodiment, the level change parameter may be a level change value or a level change number or a level change duration of the hall sensor, or the like.
And S12, if the level change parameter is within a preset parameter range value, acquiring a real-time level signal of the Hall sensor.
In one embodiment, the door body is detected based on the level change parameters, and whether the induction signal is an induction signal triggered by mistake or an induction signal generated by opening and closing the door by a user is determined.

And S23, if the duration is less than the preset duration, determining that the level change parameter is not within a preset parameter range value.
When the duration is longer than the preset duration, the level change parameter can be determined to be within the preset parameter range value, and the induction signal can be an induction signal generated by opening or closing the door by a user; when the duration is less than the preset duration, it may be determined that the level change parameter is not within the preset parameter range value, and it indicates that the sensing signal may be a sensing signal generated by triggering the hall sensor due to oscillation.

And S32, if the oscillation frequency is less than the preset frequency, determining that the level change parameter is within a preset parameter range value.
And S33, if the oscillation frequency is greater than the preset frequency, determining that the level change parameter is not within a preset parameter range value.
When the oscillation frequency is less than the preset frequency, the level change parameter can be determined to be within the preset parameter range value, and the induction signal can be an induction signal generated by opening or closing a door by a user; when the oscillation frequency is greater than the preset frequency, it can be determined that the level change parameter is not within the preset parameter range value, and the sensing signal is probably the sensing signal generated by triggering the hall sensor due to the oscillation.

Referring to fig. 2, an operation flowchart of a method for detecting opening and closing of a door according to an embodiment of the present invention is shown.
Specifically, after receiving the sensing signal of the hall sensor, the hall sensor does not immediately perform action triggering, but enters time slice verification in a short time, after entering the time slice stage, the hall sensor is monitored for stability, the level change in the period is recorded, after the time slice is completed, the level state of the hall sensor is read again, the final level state is judged and recorded, and subsequent logic judgment is performed according to the result so as to determine whether the door body is opened or closed.

if the oscillation times are smaller than preset times, determining that the level change parameter is within a preset parameter range value;
and if the oscillation times are greater than the preset times, determining that the level change parameter is not within a preset parameter range value.
The embodiment of the invention also provides a door body device for filtering oscillation, and referring to fig. 4, a schematic structural diagram of a door body for filtering oscillation provided by an embodiment of the invention is shown.
The door body is suitable for the door body opening and closing detection method according to the embodiment, wherein as an example, the door body for filtering oscillation may include: a door frame 1 and a main door 2;

Referring to fig. 5, a schematic diagram of detecting a door body for filtering oscillation according to an embodiment of the present invention is shown.
In one embodiment, when the magnet 4 is far away from the hall sensor or not in the sensing range of the hall sensor, the level of the hall sensor will not change, and the whole system considers that the physical device is in the "on" state.
If the magnet 4 enters the sensing range of the Hall sensor, the Hall sensor is switched between high and low levels, so that the system considers that the physical device is in an off state.
If the magnet 4 enters the induction range of the Hall sensor, the magnetic field starts to play a role, and after the magnetic field reaches a certain strength, the magnetic field can be sensed by the Hall sensor.
When magnet 4 got into hall sensor response scope, hall sensor produced the high-low level switching to transmit the change state of level to the host computer through the IO passageway and handle, if the magnetism device gets into repeatedly in the short time and leaves the response scope during this time, then hall sensor will transmit the high-low voltage change that produces during this time to the host computer in proper order.
The upper computer (usually a single chip microcomputer) enters a time slice state after receiving the level change at the IO port, monitors and records the level change of the Hall sensor in real time within the time slice range, does not perform subsequent logic judgment and processing before the time slice is completed, and prevents the magnetic device from repeatedly leaving and entering to cause intensive state change, thereby causing system misjudgment to cause subsequent logic disorder.
And subsequent logic processing is carried out according to the high and low level states of the Hall sensor, so that the requirement is accurate, and the triggering of wrong logic processing is prevented.
