Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example one
What two-way access control needs to solve urgently is the problem that face identification returns, and face identification has very big difference with other control methods such as modes such as two-dimensional code, password, IC-card, fingerprint, and other modes are contact, and when the card swiping takes place, the card swiping user should have been beside the floodgate machine. However, the face recognition is non-contact, and when the face recognition can recognize a face, the user brushing the face does not necessarily reach the gate, and may have a distance of half a meter to one meter. After long-distance identification, the requirement for short-distance passing can be interrupted; face identification returns through the back, is discerned once more, can trigger reverse clearance, blocks to come to personnel current, and at this moment, the personnel that return do not have current requirement, but because of being passed by face identification, control floodgate machine, cause to come to personnel blocked, bring inconvenience for the user. In order to solve the problem that the normal passing sequence is interrupted by recognizing the face again after the face is recognized, the embodiment provides a bidirectional access control method, which is shown in fig. 1 and mainly comprises the following steps:
s1: acquiring traffic information generated after processing identity identification information, wherein the identity identification information is face identification information, and the traffic information comprises a traffic person ID, identification time of the identity identification information and a traffic direction;
after the identification information of the passers is acquired, the identification information needs to be checked firstly, and the corresponding passers-by information is generated only after the check is passed; the passing information comprises a passing direction besides the ID of a passing person and the identification time of the identification information; for the bidirectional entrance and exit, the passing direction is generally an entrance direction or an exit direction, and of course, the passing direction may also be represented by an identification code, for example, the identification code "0" represents "entrance", the identification code "1" represents "exit", the specific representation manner of the passing direction is not limited, and the bidirectional entrance and exit direction may be distinguished.
S2: comparing the current traffic information with traffic information which has the same traffic pedestrian ID and identification time earlier than the current traffic information, and deleting the current traffic information if the traffic directions of the current traffic information and the traffic information are opposite and the interval of the identification time is within a first preset time; otherwise, adding the current traffic information into a message queue, wherein the message queue is used for sequencing the traffic information according to the identification time;
sequencing the traffic information according to the sequence of the identification time of the identity identification information to form a message queue, and issuing the traffic information in the message queue to an entrance guard actuating mechanism to be executed according to the sequence;
the method comprises the following steps of detecting current traffic information before adding the current traffic information into a message queue, specifically: comparing the current traffic information with traffic information which has the same traffic pedestrian ID and identification time earlier than the current traffic information, if the traffic directions of the current traffic information and the traffic information are opposite and the interval of the identification time is within a first preset time, judging that the current traffic information is a face identification back signal, and deleting the current traffic information; otherwise, deleting the traffic information which has the same traffic pedestrian ID and the identification time is earlier than the current traffic information in the message queue, and adding the current traffic information into the message queue. If the passing information with the same passing person ID in the message queue is not deleted, the current passing information is preferentially compared with the passing information with the same passing person ID in the message queue and the shortest identification time interval between the current passing information and the passing information; both ways are within the scope of protection of the present embodiment.
Fig. 2 is a flowchart of the method for determining a face recognition return signal according to this embodiment, and referring to fig. 2, after passing information of a face recognition signal is detected, it is first checked whether the ID is already in a message queue according to a passer ID, if not, the passing information is added to the message queue to indicate that the passing information is a new passing record and is not a face recognition return signal; if so, checking whether the passing direction of the current passing information is the same as the passing direction of the passing information in the message queue, if so, deleting the passing information in the message queue, adding the current passing information into the message queue to indicate that the current passing information is a new passing record, and identifying a return signal by a non-human face; if not, checking whether the difference between the identification time of the current passing information and the identification time of the passing information in the message queue is greater than a first preset time, wherein in the embodiment, the first preset time is 3 minutes, if so, deleting the passing information in the message queue, adding the current passing information into the message queue, and indicating that the current passing information is a new passing record and is not a human face identification return signal; if not, judging that the current traffic information is a face recognition return signal, and discarding the current traffic information.
S3: and sequentially extracting the traffic information from the message queue and issuing the traffic information to the entrance guard actuating mechanism so that the entrance guard actuating mechanism opens the door according to the traffic direction in the traffic information.
Further, in order to solve the problem that the continuous traffic of multiple persons in the same direction is easily interrupted by the opposite traffic demand, the embodiment provides an effective solution, and on the basis of the bidirectional entrance and exit control method, the method further comprises the following steps:
sequentially traversing the rest of the traffic information with the identification time later than the current traffic information in the message queue, and if the traffic direction of any traffic information is the same as the traffic direction of the current traffic information and the interval of the identification time of the two is within a second preset time, advancing the sequence of the traffic information in the message queue to the rear of the current traffic information; of course, if the sequence of the pass information in the message queue is originally immediately behind the current pass information, the sequence does not need to be advanced any more; in this embodiment, the second preset time is 3 seconds;
when the passing direction of two or more pieces of passing information is the same as that of the current passing information and the interval of the identification time of the two pieces of passing information is within a second preset time, the two or more pieces of passing information are still sequenced in advance according to the sequence of the identification time of the two or more pieces of passing information to form an optimized message queue; i.e. the two or more traffic information after the adjustment are sorted in the same order as they were in the message queue without adjustment.
In addition to adjusting and optimizing the sequence of the passage information in the message queue, the present embodiment also monitors and sets the device attributes of the access control executing mechanism, where the device attributes include a use state and a passage method; the method specifically comprises the following steps:
generating a door opening command according to the current traffic information extracted from the message queue and issuing the door opening command to the door control execution mechanism, wherein the door opening command comprises the traffic direction of the door control execution mechanism;
acquiring the use state and the passing direction of the access control actuating mechanism according to a preset sampling frequency, and starting a state monitoring timer with second preset time if the use state of the access control actuating mechanism is busy;
when the passing information in the same passing direction as that of the access control actuating mechanism is received within second preset time, resetting the state monitoring timer and timing again;
and when the timing time of the state monitoring timer reaches a second preset time, switching the passing direction of the access control actuating mechanism to be the opposite direction of the current passing direction.
In this embodiment, the device status includes busy and idle, busy indicates that the gate has a door opening command and is executing, idle indicates that the gate does not have a door opening command and is detecting every 3 seconds, if there is a command and is executing, the status is busy, and meanwhile, a 3-second status detection timer is started, if there is traffic information in the same direction within 3 seconds, the timer is reset to zero and starts timing again, so as to ensure continuous preferential traffic in the same direction, and if the time of 3 seconds arrives, the running direction of the gate is switched to the reverse direction, and a reverse direction processing flow is started.
In this embodiment, after obtaining the traffic information generated after processing the identification information, first, a count value corresponding to a traffic direction included in the traffic information is incremented by one; after the state monitoring timer is started and a door opening command is issued, the count value corresponding to the passing direction is reduced by one; and judging whether the traffic information with the same traffic direction as the access control actuating mechanism is received within a second preset time by detecting whether the count value corresponding to the current traffic direction is larger than zero.
Fig. 3 is a flowchart of a method for processing a pass in the same direction according to this embodiment, and referring to fig. 3, after a pass is detected, it is first determined whether the pass is an in-out signal caused by face recognition returning according to the above method, and if yes, no processing is performed; if the signal is not an in-out signal caused by face recognition returning, adding one to the count value corresponding to the passing direction; then judging the state of the gate, if the gate is idle, switching to a busy state, starting a 3-second timer and issuing a door opening command, setting the passing direction of the gate as the current direction, subtracting 1 from the count value of the passing direction, judging whether the count value of the current passing direction is greater than 0, if so, indicating that the same-direction passing information exists, continuing circulation, otherwise, ending; if the gate is busy, checking whether the passing direction of the passing information is the same as the current passing direction of the gate, if so, re-timing by the timer and issuing a door opening command, subtracting 1 from the count value of the current passing direction to ensure that the passing is preferentially carried out in the same direction; judging whether the count value of the current passing direction is greater than 0, if so, continuing to circulate, and if not, ending; if the current passing direction is the reverse direction, the current passing direction is not released temporarily, whether the count value of the current passing direction is larger than 0 is judged, if so, the circulation is continued, and if not, the circulation is ended.
It should be noted that the above-mentioned same-direction traffic priority processing method is also applicable to non-face recognition application scenarios, and at this time, after the traffic information is detected, it is not necessary to determine whether the traffic information is an incoming and outgoing signal caused by face recognition returning, and the subsequent processing flow is directly entered.
Fig. 4 is a flow chart of the direction switching of the gate provided in the present embodiment, and as shown in fig. 4, the present embodiment detects the gate state every 3 seconds; if the timing time of 3 seconds is up, the current direction traffic (including continuous traffic) is finished, if the state of the gate is idle, an error is reported, and a 3 second timer is started only when the state of the gate is busy; the state of the gate is busy, whether the counter direction count is 0 is detected, if so, the state of the gate is switched to idle; if not, setting the current passing direction as the reverse direction, starting a new 3-second timer, running the 3-second timer only once discontinuously after starting, issuing a door opening command with the number equal to the current direction count, and clearing the direction count value.
Further, the bidirectional access control method provided in this embodiment further includes: detecting the traffic information in the message queue at regular time, and deleting the traffic information of which the difference between the identification time of the identity identification information in the message queue and the current time exceeds third preset time; in this embodiment, the third preset time is taken as 3 minutes;
