step S100: and acquiring access control state information.

The state corresponding to the door control state information is the current state of the door control, and comprises the state when the door lock is locked and the state when the door lock is opened, and the state of the gate is monitored and determined.

Step S101: and acquiring the identification state information of the preset human body identification area when the state corresponding to the access control state information is consistent with the preset locking state.

The locking state is a state of the gate when the gate is closed and cannot be directly pushed open, and when the state corresponding to the gate control state information is consistent with the locking state, the gate is closed, and the gate cannot directly enter a corridor at the moment; the human body identification area is an area which is set in advance by a worker and is in front of the installation position of the calling device and can be used for people to walk, the specific area size is set by the worker according to actual conditions, the state corresponding to the identification state information is the state of identifying the person in the area, and the pyroelectric sensor is installed above the entrance guard to determine the human body detection condition.

Step S102: and judging whether the state corresponding to the identification state information is consistent with a preset in-place state.

The in-place state is the recognition state of the staff when the staff detects the staff in the human body recognition area, and the purpose of judgment is to know whether the staff exists in the human body recognition area.

Step S1021: if the state corresponding to the identification state information is consistent with the in-place state, controlling the preset in-place duration to start timing.

When the state corresponding to the identification state information is consistent with the in-place state, indicating that a person exists in the human body identification area, wherein the person possibly needs to perform door opening operation and needs further analysis; the initial value of the in-place duration is 0, and the timing of the in-place duration is controlled to know the specific time of the person in the human body identification area so as to determine whether the person needs to perform the access control operation.

Step S1022: and if the state corresponding to the identification state information is inconsistent with the in-place state, controlling the in-place time period to perform zero treatment.

When the state corresponding to the identification state information is inconsistent with the in-place state, the fact that no person is in the human body identification area at the moment is indicated, namely no person needs to perform access control operation, and the in-place time length is controlled to be zero.

Step S103: and when the in-place time length is consistent with the preset demand time length, opening a protective cover covering the calling device, and activating the calling device.

The required time length is the minimum time length in the human body identification area when the personnel is set by the staff to carry out the access control operation, and when the in-place time length is consistent with the required time length, the personnel is not the personnel passing through the area, namely the personnel needs to carry out the access control operation, and the protective cover is controlled to be opened to activate the calling device for use; the protective cover is covered on the outer surface of the calling device when the calling device is not used, so that the calling device is not easy to damage, the protective cover can be moved through driving devices such as a motor, the specific structure is set by a worker, and meanwhile, the calling device only needs standby operation when not used, real-time activation is not needed, and power consumption of the calling device is reduced.

Referring to fig. 2, after the calling device is activated, the method for controlling the access control calling device further includes:

step S200: shooting height information and shooting image information are acquired.

The image corresponding to the shot image information is an image shot by a camera for face recognition on the calling device, and the height value corresponding to the shot height information is the height value of the calling device when the shot image is acquired.

Step S201: and carrying out feature recognition in the image corresponding to the shot image information to determine and recognize the face features.

The face recognition features are faces in the shot image, and the method for determining the faces in the image can be firstly determined through neural network learning, and then the corresponding face recognition is carried out.

Step S202: and acquiring pixel height information of each point position in the face feature identification.

The height value corresponding to the pixel height information is the height of each point in the image of the human body characteristic, namely, an X-Y coordinate system is established by the image, and the pixel height is the ordinate of each point.

Step S203: and determining the pixel height information with the maximum corresponding value according to a preset ordering rule in the same identified face feature, determining the point position corresponding to the pixel height information as the highest point of the human body, and acquiring the point position acquisition distance according to the highest point of the human body.

The sorting rule is a method which is set by staff and can sort the numerical values, such as an bubbling method, the highest point in the face characteristic can be determined and identified through the sorting rule, and the point is defined as the highest point of a human body for identification, so that the distinction of different points can be conveniently realized; the point position acquisition distance is a distance value from the camera to the highest point of the body in the direction right in front of the camera, and can be determined by trigonometric function calculation through the linear distance from the camera and the corresponding angle when the highest point of the human body is shot.

Step S204: and determining the point position acquisition distance with the minimum value according to the ordering rule, defining the point position acquisition distance as a door opening distance, and defining the identification face feature corresponding to the door opening distance as a door opening face feature.

The highest point of the human body closest to the calling device can be determined through the ordering rule, the distance is defined as the door opening distance for identification, and the person operating the calling device is marked through defining the door opening face characteristics, so that the subsequent further analysis is facilitated.

Step S205: and judging whether the door opening face features are in a preset resident feature set or not.

The resident characteristic set is a face characteristic set which is recorded in the calling device in advance and can be used for opening the entrance guard directly through face recognition, and the purpose of judgment is to know whether the person can directly open the entrance guard through face recognition at the moment.

Step S2051: and if the door opening face features are in the resident feature set, controlling the door access to be opened.

When the door opening face features are in the resident feature set, the instruction can directly open the access control through face recognition, and the access control is controlled to open at the moment.

Step S2052: if the door opening face features are not in the resident feature set, calculating according to the door opening distance, the highest point of the human body on the door opening face features and shooting height information to determine the human body height information.

When the door opening face features are not in the resident feature set, the person cannot open the access control through face recognition, namely the person needs to use a calling device to open the access control; the height value corresponding to the human body height information is the height of the door opener, and analysis, calculation and determination can be carried out according to the condition of the image shot at the shooting height.

Step S206: and calculating according to the human body height information and a preset height adjustment value to determine the using height of the device.

The height value is the height value which is set by a worker and is required to be downwards adjusted at the highest point of the human body so that the right center of the screen of the calling device can be opposite to the position around the eyes of the user, and the using height of the device is the height of the calling device which can be more suitable for the user to use, and can be determined by subtracting the height value corresponding to the height information of the human body from the height value of the adjustment.

Step S207: and determining difference value height information and moving direction information according to the shooting height information and the using height of the device, and controlling the calling device to move the height distance value corresponding to the difference value height information along the direction corresponding to the moving direction information.

The height value corresponding to the difference height information is the distance value of the current calling device from the position required by the position distance, the direction corresponding to the moving direction information is the direction in which the calling device can move to the proper position, and the calling device is controlled to move along the direction corresponding to the moving direction information by the height distance value corresponding to the difference height information, so that the calling device can move to the device using height, and a user can operate the calling device conveniently.

Referring to fig. 3, if the door opening face feature is in the resident feature set, the method for controlling the access calling device further includes:

step S300: counting is carried out according to the identified face characteristics to determine the number of the identified faces.

When door opening face features are in the resident feature set, there may be cases where an illegal person follows to try to enter the corridor, requiring further analysis; the number of the identified faces is the total number value of the determined identified face features, and can be determined by counting the identified face features one by one.

Step S301: and judging whether the number of the identified faces is more than one.

The purpose of the judgment is to know whether or not an illegal person trailing situation is likely.

Step S3011: and if the number of the identified faces is not more than one, controlling the entrance guard to open.

When the number of the identified faces is not more than one, the situation that the personnel trailing exists is indicated, and the entrance guard is normally controlled to be opened.

Step S3012: if the number of the identified faces is greater than one, defining the identified face features except the door opening face features as face features to be detected, and defining the point position acquisition distance corresponding to the face features to be detected as the distance to be detected.

When the number of the identified faces is more than one, the situation that personnel trailing possibly exists is indicated, and further analysis is needed; and defining the face features to be detected to distinguish different face features, and defining the distance to be detected to mark the point location acquisition distance corresponding to the face features to be detected, so that the subsequent analysis by data is facilitated.

Step S302: and calculating a difference value according to the door opening distance and the distance to be measured to determine the distance to be separated.

The distance between the door opening person and the person to be detected is a distance value on the straight line facing the direction of the camera, and the door opening distance is subtracted from the distance to be detected to determine.

Step S303: judging whether at least one distance is larger than a preset safety distance.

The safety distance is the maximum distance set by the staff and used for identifying that the person to be detected is not the person with the door opened in the trailing mode, and the aim of judgment is to know whether the person is possibly trailing the person.

Step S3031: and if at least one of the separation distances is not greater than the safety distance, controlling the entrance guard to open.

When at least one of the separation distances is not greater than the safety distance, the possibility of personnel trailing is not shown, and the entrance guard is normally controlled to be opened.

Step S3032: if at least one distance is greater than the safety distance, determining human height information to control the calling device to move, displaying a preset open-door questionnaire on the calling device after the calling device moves, and acquiring a questionnaire answer in real time.

When at least one distance is greater than the safe distance, indicating that a person trailing is possible, further analysis is required; the method for determining the height information of the human body is consistent with the steps S2052-S207, the questionnaire for opening the door is a questionnaire for inquiring whether the door opener normally opens the door, and the staff sets the questionnaire content in advance; the questionnaire reply is a new reply signal received on the open-door questionnaire, and can be input by a door operator by touching a display screen on the calling device.

Step S304: and controlling the entrance guard to open when the questionnaire answer is consistent with the preset permission answer within the preset answer duration, otherwise, maintaining the original state of the entrance guard.

The reply time length is the time length which is set by the staff and can be used for processing the questionnaire of the door opening by the door opening staff, the reply is the questionnaire reply when the door opening staff selects to continue opening the entrance guard, when the door opening staff selects to allow the reply on the questionnaire, the condition that the user considers that the illegal molecule trailing does not exist is indicated, the entrance guard is normally controlled to be opened at the moment, when the questionnaire reply is inconsistent with the allowed reply in the reply time length, the condition that the user does not determine the personnel or considers that the personnel is possibly the illegal molecule trailing is indicated, the entrance guard is not opened at the moment, and the safety in the corridor is ensured.

Referring to fig. 4, when there is at least one distance greater than the safe distance, the entrance guard calling device control method further includes:

step S400: and determining door opening points on a preset distance arrangement straight line according to the door opening distance, determining to-be-measured points according to the to-be-measured distance, and counting according to the to-be-measured points to determine the number of to-be-measured points.

The distance arrangement straight line is a straight line penetrating through a camera on the calling device and extending in the right front direction, the door opening point is a point position on the distance arrangement straight line, which is the door opening distance from the camera, and the to-be-detected point is a point position on the distance arrangement straight line, which is the to-be-detected distance from the camera; the number of the points to be measured is the total number value of the points to be measured on the distance arrangement straight line, and can be determined by counting the points to be measured one by one.

Step S401: and establishing a safety interval with the width being a safety distance along a preset far direction at the door opening point, and judging whether a point to be detected exists in the safety interval.

The distance direction is the direction which is in front of the camera and away from the camera on the distance arrangement straight line, a safety interval is established to detect the personnel which basically do not follow, and the purpose of judgment is to know whether the personnel which determine the new personnel which do not follow exist.

Step S4011: if the safety interval has the point to be tested, reestablishing the safety interval according to the point to be tested which is farthest from the door opening point in the safety interval until the safety interval has no point to be tested.

When a to-be-measured point is located in the safety zone, the fact that the to-be-measured point is close to the door opening person is indicated, at the moment, the to-be-measured point person can be determined not to be a trailing person, at the moment, the safety zone is reestablished by the person to continue detection until the to-be-measured point is not located in the defined safety zone, and therefore misjudgment caused by the fact that a lot of persons are far away from the door opening person is avoided when the number of persons is large.

Step S4012: if no to-be-measured point exists in the safety interval, counting according to the to-be-measured points in the safety interval to determine the number of the effective point positions.

When no measuring point is to be measured in the safety interval, the personnel which are basically not trailing personnel are determined, and the specific number of the safety personnel, namely the number of effective points, can be obtained by counting according to the determined number of the safety personnel.

Step S402: and judging whether the number of the effective point positions is equal to the number of the point positions to be tested.

The purpose of the determination is to know whether all of the people under test are identified as not trailing people.

Step S4021: and if the number of the effective points is equal to that of the points to be detected, controlling the entrance guard to open.

And the number of the effective points is equal to that of the points to be detected, and all the personnel are determined not to be trailing personnel, and the entrance guard is normally controlled to be opened at the moment.

Step S4022: if the number of the effective points is not equal to the number of the points to be tested, the calling device is controlled to move so as to display the open questionnaire.

When the number of effective points is not equal to that of the points to be detected, the fact that the person is considered to be possibly trailing person is indicated, and then the open questionnaire is displayed normally.

Referring to fig. 5, when the number of effective points is not equal to the number of points to be tested, the method for controlling the access control calling device further includes:

Step S500: and defining the to-be-detected points which are not in the safety interval as detection points, and defining corresponding to-be-detected face features as abnormal face features according to the detection points.

The detection points are defined to distinguish different points to be detected, so that subsequent analysis is facilitated, meanwhile, the abnormal face features are defined to mark the face features to be detected at the detection points, and subsequent calling analysis on the face features is facilitated.

Step S501: judging whether the abnormal face features and the door opening face features are in the same preset permission set or not.

The permission set is a set which is input by a worker in advance and used for binding the worker, namely, the abnormal worker is considered to be the trailing worker of the door opener, and the judgment purpose is to know whether the current abnormal worker is the trailing worker of the door opener.

Step S5011: and if the abnormal face features and the door opening face features are in the same permission set, controlling the door access to be opened.

When the abnormal face features and the door opening face features are in the same permission set, the abnormal person is not likely to be the trailing person of the door opening person, and the door access opening operation is performed normally.

Step S5012: if the abnormal face feature and the open door face feature are not in the same permission set, the calling device is controlled to move to display the open door questionnaire, and the abnormal face feature and the open door face feature are bound to the empty permission set when the questionnaire answer is consistent with the permission answer.

When the abnormal face features and the door opening face features are not in the same permission set, the abnormal person is possibly a trailing person of the door opening person, and the door opening questionnaire is normally displayed for reply; when the questionnaire answer is consistent with the permission answer, the door opener is used for determining that the abnormal person is not a trailing person, and the abnormal person is bound into an empty permission set to fill the permission set, so that the abnormal person can be automatically identified when the person appears again next time, and the door opener is controlled to open.

Referring to fig. 6, after the calling device moves, the method for controlling the access control calling device further includes:

step S600: and judging whether the door opening face features are in the resident feature set or not.

The purpose of the judgment is to know whether the open questionnaire needs to be displayed after the calling device moves at the moment.
