Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses an access control method, an access control device and an access control system, which can intelligently modify the trigger mode of the access control system according to the trigger time point and the trigger mode of access trigger operation acquired by access control equipment, and improve the safety of the access control system. The invention is applicable to other places with higher requirements on safety protection besides office buildings and residential districts.

First, the access control method according to the embodiment of the present invention will be described in detail. The access control method provided by the embodiment of the invention is applied to the technical field of security protection, generally, the time of a working member or a student going home or working every day is a fixed time period, and for a set access control system, the triggering mode for triggering the access control system to be opened is also fixed, such as card swiping triggering, fingerprint triggering, facial information triggering and the like, more card swiping triggering is applied, once the access control card is lost, potential safety hazards can be caused, in addition, biological characteristics exposed outside a human body are easily copied, and therefore, the safety of the existing access control system is lower, and the access control method provided by the embodiment of the invention can improve the safety of the access control system. In addition, the execution subject of the access control method provided by the embodiment of the invention is an access control device.

It should be noted that the access control system may include a control device, an access control device, and a door. The control device may be a host or a server, and the control device is an execution subject of the access control method provided by the embodiment of the present invention, that is, the access control method provided by the embodiment of the present invention is applied to the control device. The entrance guard equipment can gather the entrance guard trigger operation of user and the switching of control door. The specific hardware configuration of the access control device is determined according to the type of the access control system, and is a hardware configuration in the prior art, which is not limited herein.

Referring to fig. 1, fig. 1 is a flowchart of an access control method according to an embodiment of the present invention, including the following steps:

s101, acquiring a trigger time point and a trigger mode of the access control trigger operation in a first time period within a preset time period acquired by the access control equipment.

When the entrance guard triggers the operation, the entrance guard equipment has certain records to the trigger time point and the trigger mode of the entrance guard triggers the operation. The trigger time point is the specific time of the access control trigger operation, the trigger mode is the trigger operation of the access control equipment for opening the door in the access control system, and can be card swiping trigger, fingerprint trigger, password trigger and the like, and when the access control trigger operation is performed each time, the trigger time point and the trigger mode are in one-to-one correspondence. The preset time period is a period for counting the triggering times of the triggering mode, and the first time period is a recorded time period for triggering operation of the entrance guard.

For example, the preset time period may be one week, and the first time period may be 19:30-20:30, so that the data collected by the access control device is the trigger time point and the trigger mode within the time period of 19:30-20:30 in one week.

S102, when the triggering times of the same target triggering mode reach a first preset threshold value, determining a first average time period of the door control triggering according to a triggering time point of the first time period in a preset time period and a preset first time difference.

The control device can judge whether the triggering times of the same target triggering mode reach a first preset threshold value or not for the triggering time point, the triggering times and the triggering mode of the access control triggering operation in the first time period within the acquired preset time period, and when the triggering times of the same target triggering mode reach the first preset threshold value, the first average time period of the access control triggering is determined according to the triggering time point and the preset first time difference of the first time period within the preset time period. The preset first time difference means that the access control verification can be carried out within a certain time period before and after the average trigger time point, the first average time period is a time period corresponding to the preset first time difference before and after the average trigger time point, and the first average trigger time point is an average value of the trigger time points within a preset time period; moreover, it is reasonable that the preset first time difference can be set by the control device or by the user.

For example: according to the triggering time points and the triggering modes of the access control device within the time period 19:30-20:30 in the week collected in the step S101, for example, the triggering modes include: fingerprint triggering and card swiping triggering, wherein the number of times of fingerprint triggering is 5, the number of times of card swiping triggering is 2, and if the first preset threshold is 4, the number of times of fingerprint triggering reaches the first preset threshold, and the fingerprint triggering is used as a target triggering mode. The first preset threshold is a value set by the control equipment or set by a user. Determining a first average time period of the door control trigger according to a trigger time point acquired within a time period of 19:30-20:30 within a week and a preset first time difference, wherein the preset first time difference can be automatically generated by a control device or set by a user, the preset first time difference means that door control verification can be performed within a certain time period before and after the average trigger time point, the first average time period is a time period corresponding to the preset first time difference before and after the average trigger time point, for example, the average trigger time point is 20:00, the first time difference is 15 minutes, and then the first average time period is 19:45-20: 15.

S103, generating a first verification mode according to the first average time period and the target trigger mode, and generating a second verification mode according to a first opposite time period and a preset complex trigger mode, wherein the first opposite time period is a time period not in the first average time period.

Specifically, after the first average time period is obtained, a first verification mode may be generated according to the first average time period and a target trigger manner, and a second verification mode may be generated according to a first opposite time period and a preset complex trigger manner, where the first opposite time period is a time period not in the first average time period. It can be understood that through the setting of the first verification mode, the release of the access control can be completed by a single mode for a legal user in a legal time period; and through the setting of the second verification mode, the following steps can be carried out: when the trigger time point of the access control trigger operation is not in the first average time period, the authentication mode of the control equipment, namely the trigger mode is very complex, so that lawless persons without permission are more difficult to make a law violation, the safety of the access control system is improved, and the experience performance of users is also improved. The preset complex trigger mode at least includes: a combination of at least two of a card swipe trigger, a fingerprint trigger, a facial information trigger, and a voice trigger.

For example: the first average time period in S102 is 19:45-20:15, the target trigger mode is fingerprint trigger, and the first verification mode is: the trigger time point is within a time period of 19:45-20:15 and the trigger mode is fingerprint trigger, the first opposite time is a time period not within the first average time period, it is understood that the first opposite time is 00:00-19:45 and 20:15-24:00, then the second authentication mode is: the triggering time point is within the time period of 00:00-19:45 or 20:15-24:00, and the triggering mode is a preset complex triggering mode.

It should be noted that the access control device in the embodiment of the present invention may simultaneously acquire the trigger time point, the trigger times, and the trigger modes of the access control trigger operation in different time periods within a preset time period, and the verification modes generated in different time periods are not mutually affected, but the time period corresponding to the preset complex trigger mode may be changed in different time periods.

For example: the first time period is 19:30-20:30, the first time period corresponds to the first verification mode, and in a third time period of 11:30-12:30, if the control device also acquires a trigger time point and a trigger mode of the access control trigger operation sent by the access control device, and correspondingly generates a third verification mode, the time period corresponding to the second verification mode is changed to a time period which is not in the first average time period and is not in the third average time period.

And S104, when receiving the trigger time point to be analyzed and the trigger mode to be analyzed of the entrance guard trigger operation sent by the entrance guard equipment, judging whether the trigger time point to be analyzed and the trigger mode to be analyzed meet the first verification mode or the second verification mode.

If the judgment result in the S104 is yes, executing S105, and controlling the access control equipment to open the access control; and if the judgment result in the S104 is negative, executing the S106 to control the access control equipment not to open the access control.

When receiving a trigger time point to be analyzed and a trigger mode to be analyzed of the entrance guard trigger operation sent by the entrance guard device, judging whether the trigger time point to be analyzed and the trigger mode to be analyzed meet a first verification mode or a second verification mode, and executing different operations according to different judgment results. Specifically, when the trigger time point to be analyzed and the trigger mode to be analyzed are judged to meet one of the first verification mode and the second verification mode, the access control equipment is controlled to control the access control equipment to open the access control, and if the two verification modes are not met, the access control equipment is controlled to control the access control equipment not to open the access control.

It should be noted that, the to-be-analyzed triggering manner in the embodiment of the present invention satisfies the first verification mode or the second verification mode, which means that the to-be-analyzed triggering manner is the same as the triggering manner in the first verification mode or the second verification mode in terms of manner and information. For example, the trigger pattern in the first verification mode is a fingerprint trigger, and then the trigger pattern to be analyzed is not only a fingerprint trigger, but also the fingerprint in the fingerprint trigger is to be consistent with the fingerprint in the fingerprint trigger of the first verification mode. Of course, other types of triggers such as password trigger, card swiping trigger, face information trigger and the like are similar to fingerprint trigger, and are not described herein again.

Taking the first verification mode and the second verification mode in S103 as an example, the first verification mode is: the triggering time point is within a time period of 19:45-20:15, the triggering mode is fingerprint triggering, and the second verification mode is as follows: the triggering time point is within the time period of 00:00-19:45 or 20:15-24:00, and the triggering mode is a preset complex triggering mode. If the received trigger time point of the entrance guard trigger operation sent by the entrance guard equipment is 19:50 and the trigger mode is fingerprint trigger, the trigger time point and the trigger mode of the entrance guard trigger operation meet a first verification mode, and the control equipment controls the entrance guard equipment to open the entrance guard; if the triggering time point of the access control triggering operation is 20:30 and the triggering mode is fingerprint triggering, the triggering time point and the triggering mode of the access control triggering operation do not meet the first verification mode and the second verification mode, and the control equipment controls the access control equipment not to open the access control, namely, the door is still in a closed state.

As can be seen, in the access control method according to the embodiment of the present invention, by acquiring the trigger time point and the trigger mode of the access trigger operation acquired by the access control device, when it is determined that the number of triggers of the same target trigger mode reaches the first preset threshold, the first verification mode and the second verification mode are generated according to the trigger time point, the target trigger mode and the preset complex trigger mode, and when it is determined that the trigger time point to be analyzed and the trigger mode to be analyzed of the access trigger operation sent by the access control device satisfy the first verification mode or the second verification mode, the access control device is controlled to open the access, otherwise, the access control device is controlled not to open the access. According to the embodiment of the invention, the triggering mode of the access control equipment can be intelligently modified according to the acquired data, so that the safety of the access control system is improved.

Optionally, in an implementation manner, generating the first verification pattern according to the first average time period and the target trigger manner includes:

and generating a first verification mode which controls the opening condition of the access control equipment to be a first preset condition, wherein the first preset condition is that the trigger time point is in a first average time period and the trigger mode is a target trigger mode.

Correspondingly, generating a second verification mode according to the first reverse time period and a preset complex trigger mode comprises the following steps:

and generating a second verification mode which controls the opening condition of the access control equipment to be a second preset condition, wherein the second preset condition is that the triggering time point is in a first opposite time period and the triggering mode is a preset complex triggering mode, and the first opposite time period is a time period which is not in the first average time period.

For example: if the first average time period is 11:30-12:30 and the target trigger mode is password trigger, the generated first verification mode is as follows: the trigger time point is within the time period of 11:30-12:30 and the trigger mode is password trigger. The second verification mode is: the triggering time point is within a time period of 00:00-11:30 or 12:30-24:00, and the triggering mode is a preset complex triggering mode, wherein the preset complex triggering mode can be the combined triggering of card swiping triggering and fingerprint triggering.

Optionally, in an implementation manner, the step of determining a first average time period of the access control trigger according to a trigger time point of the first time period within a preset time period and a preset first time difference includes:

calculating a first average time point of trigger time points of a first time period in a preset time period;

Taking a preset time period of one week as an example, if the trigger time points of the access control triggering operation are T1, T2, T3, T4, T5, T6, and T7, respectively, the first average time point is T ═ T (T1+ T2+ T3+ T4+ T5+ T6+ T7)/7. The first time difference is preset to be T, and then the first average time period is (T-T, T + T).

Optionally, in an implementation manner, the step of calculating the first average time period of the access trigger according to the first average time point and the preset first time difference includes:

if the first average time point is T, the first time difference is preset to be T,

determining a first time point T-T which is earlier than the first average time point T by a preset first time difference T;

determining a second time point T + T which is later than the first average time point T by a preset first time difference T;

and determining the first time point T-T as the starting time point of the first average time period, and determining the second time point T + T as the ending time point of the first average time period.

It should be noted that, the method for calculating the first average time period of the entrance guard trigger according to the first average time point and the preset first time difference includes, but is not limited to, the above method, and there are many methods, which are not limited herein.

Optionally, in an implementation manner, the determining whether the trigger time point to be analyzed and the trigger manner to be analyzed satisfy the first verification mode includes:

judging whether the trigger time point to be analyzed is in the first average time period or not and whether the trigger mode to be analyzed is a target trigger mode or not;

and if the trigger time point to be analyzed and the trigger mode to be analyzed meet the first verification mode, determining that the trigger time point to be analyzed and the trigger mode to be analyzed do not meet the first verification mode.

Optionally, in an implementation manner, the determining whether the trigger time point to be analyzed and the trigger manner to be analyzed satisfy the second verification mode includes:

judging whether the trigger time point to be analyzed is in a second average time period or not and whether the trigger mode to be analyzed is a preset complex trigger mode or not;

and if the trigger time point to be analyzed and the trigger mode to be analyzed meet the second verification mode, determining that the trigger time point to be analyzed and the trigger mode to be analyzed do not meet the second verification mode.

It can be understood that, when the trigger time point to be analyzed and the trigger mode to be analyzed of the access control trigger operation sent by the access control device are received, the trigger time point to be analyzed is within the first average time or not within the first average time period, that is, only one of the first verification mode and the second verification mode can be verified. And, first verification mode and second verification mode are the verification mode that trigger time point and trigger mode bound, namely, when in first average time quantum, can satisfy first verification mode only when trigger mode is the target trigger mode, and controlgear just can control entrance guard's equipment and open entrance guard, when not in first average time quantum, can satisfy second verification mode only when trigger mode is for predetermineeing complicated trigger mode, and controlgear just can control entrance guard's equipment and open entrance guard.

It should be noted that, the authorized user may cancel the current first authentication mode according to the requirement, and open the access control in any other way. After the authorized user logs in the control device, the trigger mode can be freely set, that is, the first authentication mode can also be set manually.

Optionally, in the access control method according to the embodiment of the present invention, the presetting of the complex trigger mode includes: a combination of at least two of a card swipe trigger, a fingerprint trigger, a facial information trigger, and a voice trigger.

Specifically, the embodiment of the invention can also remind the recommended user of a triggering mode with higher use safety when the first verification mode and the second verification mode are generated according to the ambient light, sound induction conditions and the like in summer time and winter time. For example, the time of day black in winter is relatively early, the facial information features are not obvious, and the facial information is triggered and excluded in a triggering mode in order to reduce the misjudgment of the control equipment. Under the condition that the corridor echo is large or the noise of the nearby environment is too large, the user is reminded, and voice triggering is not suggested to be used as a triggering mode and the like.

As shown in fig. 2, fig. 2 is another flowchart of the access control method according to the embodiment of the present invention, and on the basis of the embodiment shown in fig. 1, the access control method according to the embodiment of the present invention further includes:

s201, when receiving a to-be-analyzed trigger time point and a to-be-analyzed trigger mode of the entrance guard trigger operation sent by the entrance guard device, judging whether the to-be-analyzed trigger time point is not in a first average time period or not, and whether the to-be-analyzed trigger time point is not in the first average time period for the first time.

S202, when the judgment result is yes, setting the trigger mode corresponding to the first verification mode as a preset complex trigger mode.

Obviously, the embodiment of the invention ensures that the triggering mode used by the user is used during the access control triggering operation within the first average time period, and simultaneously ensures the safety of the access control system not within the first average time period. And when the trigger time point to be analyzed of the access control trigger operation sent by the access control device is not in the first average time period for the first time, updating the trigger mode corresponding to the first verification mode to be a preset complex trigger mode, namely, the trigger mode of the access control trigger operation is the preset complex trigger mode in the whole day. Of course, the triggering manner of the first verification mode may be further updated in the following, which is specifically described in detail in the following, and will not be described herein again.

For example: the first verification mode is: the trigger time point is within the time period of 19:45-20:15 and the trigger mode is fingerprint trigger. The second verification mode is: the triggering time point is within the time period of 00:00-19:45 or 20:15-24:00, and the triggering mode is a preset complex triggering mode. If the trigger time point of the current access control trigger operation is 12:00 and the trigger time points before the current access control trigger operation are within 19:45-20:15 time periods, the control device updates the corresponding trigger mode within 19:45-20:15 time periods in the first verification mode to a preset complex trigger mode. And the current trigger mode in the whole day is a preset complex trigger mode, so that the safety of the access control system is improved.

Optionally, in an implementation manner, in a preset time period, if it is determined that the trigger time point to be analyzed is not within the first average time period and the number of triggers of the trigger time point to be analyzed in the second time period reaches a second preset threshold,

first, a second average time point of the trigger time points of the second time period within the preset time period is determined.

And then, determining a second average time period of the door control trigger according to the second average time point and a preset second time difference.

And finally, updating the first verification mode and the second verification mode according to the second average time period and the target trigger mode.

Specifically, in a preset period, if the triggering time of the triggering time point of the access control triggering operation in the second time period reaches a second preset threshold, calculating a second average time point according to the triggering time point of the second time period in the preset period, and determining the second average time period according to the difference between the second average time point and the preset second time. Then, the first authentication mode is updated as: the triggering time point of the access control triggering operation is within the second average time period, and the triggering mode is a target triggering mode; the second verification pattern is updated as: the trigger time point of the access control trigger operation is not in the second average time period, and the trigger mode is a preset complex trigger mode.

Taking the first verification mode and the second verification mode in S103 as an example for detailed description, the current first verification mode is: the triggering time point is within a time period of 19:45-20:15, and the triggering mode is fingerprint triggering; the current second verification mode is: the triggering time point is within the time period of 00:00-19:45 or 20:15-24:00, and the triggering mode is a preset complex triggering mode. When the trigger time point of the entrance guard trigger operation is not within the first time period 19:30-20:30, but within the second time period 16:30-17: 30. The preset time period is one week, the fingerprint is triggered 6 times in the second time period of 16:30-17:30, the card is triggered 1 time, the second preset threshold value and the first preset threshold value can be the same or different, and if the second preset threshold value is 6, the triggering frequency of the password triggering reaches the second preset threshold value. If the average value of the trigger time points in the second time period 16:30-17:30 is 17:05 through calculation, the preset second time difference is 20 minutes, and the obtained second average time period is 16:45-17: 25. The preset second time difference may be the same as or different from the preset first time difference, or the preset second time difference may be automatically generated by the control device or may be set by the user. Finally, the updated first verification mode is obtained as follows: the triggering time point is within a time period of 16:45-17:25, and the triggering mode is fingerprint triggering; the updated second verification mode is: the triggering time point is not within the time period of 16:45-17:25, and the triggering mode is a preset complex triggering mode.
