The face snapshot is carried out on the current card holder by the camera installed on the entrance guard card rechecking device, and the related identity identification is obtained from the system through the snapshot real-time image personnel image.
When the captured real-time image personnel image acquires a related identity mark from the system and matches the card personnel information mark decrypted by swiping the card, the entrance guard card rechecking device performs relevance rechecking on the identification mark data received from the bus, the identity of the card and the entrance guard identification mark data stored by the entrance guard card rechecking device, the entrance guard card rechecking device prompts a passer to perform face or other biological identification, and immediately outputs the data and the password of the card identification to the entrance guard control system through a Wiegand output bus of the entrance guard card rechecking device after the matching is finished.
The access control management system matches legal authorization through the card and the password read in by the Wiegand input port, the system outputs the relay according to the access control relay configuration corresponding to the authorization information of the card, otherwise, the access control does not output the relay signal output.
If the system biological identification is not identified within the overtime time limit or the identification fails, the access control card rechecking device system does not output the data and the password of the card identification, clears the data and the password of the card identification, and waits for the next input of the data and the password of the card identification of the Wiegand bus. The system can carry out statistical analysis after rechecking of the entrance guard identity of related personnel according to the entrance guard access authorization of the signal when the door is unlocked.
After the access control management system outputs the relay signal, the access control card rechecking device transmits access authorization identity data to the access control management system, the access control server receives the final identification authorization data and equipment information of the access personnel, and the system service background records the personnel number, access time and authorization equipment of the relevant access personnel.
The entrance guard service regularly and quickly carries out statistical calculation on personnel numbers, access time and directional areas of authorized equipment. And the calculated personnel are classified according to the region classification result, and the calculation result of the region is provided for the entrance guard card rechecking device of the classification region of different regions.
The entrance guard management system statistics is issued to the identification rechecking devices of the areas where the entrance guard management system statistics is located through the entrance guard server, when the number of people in the area where the equipment is located exceeds or is less than the limited number of people, the entrance guard card rechecking devices stop inputting the read card and the password, and the area prohibits people from entering or leaving the area according to the area boundary setting in the entrance guard management system.
The number of people in the area of the access service system is calculated, an independent biological recognition system is adopted to count, count and analyze the access boundary, namely, the access management system is authorized by the boundary only capable of recognizing access, whether people are in a real area or not or when two people and a plurality of areas are crossed and enclosed, a directional area calculation method is adopted to calculate and count card swiping people at the boundary of the areas, and the total number of the people entering the areas can be counted.
As shown in fig. 2, the calculation method is correct for the conventional access mode in simple non-multi-zone nesting and zone crossing statistics:
and (3) CAn: count of area is the number of regional people n is the area { n:0 > 1},
CSn: n is the region { n:0 > 1}
CAin: number of persons CAin equal to Gin for entering area
And (3) CAn: i.e. the area An, is swiped at its boundary gn (gate n)
The total number of cans is: number of people in CAn-CAon calculation area
As shown in fig. 2: when entering a2 from a1 via G1, namely: the number of people in the system area A1 is A1-1; a2 ═ A2+1 human
The same principle is that: when entering a1 from a2 through G1, the number of system area people is a1 ═ a1+ 1; a2 ═ A2-1 human
When multiple entrance guard areas have intersection or sum relations or multiple entrance and exit gates, the following person calculation of the entrance guard areas consisting of multiple areas and multiple channels cannot be performed according to the entrance of a card reader or a human face device by passing through the passing boundaries of other areas or entering deeper layers because the number of persons entering or leaving the areas which are contained in the own areas or are parallel to the own areas cannot be calculated and eliminated by simple boundary calculation.
As described below with respect to fig. 3 and 4
Regional relationships
Cross relation of
An area is
All cross over areas
Area of packet
An area is
All merge regions
The statistical quantity of the personnel information of the two region relation models can be reduced to that of personnel entering each region:
and (3) CAn: the number of people in the region { n: 0-n natural number }, An is the region
CAin is the number of regional personnel Ain entering a card reader or a face recognition device
CAon, the number of people leaving the area, Aon
The calculation amount of card swiping for entrance and exit of the entrance guard boundary is usually calculated, that is, counting statistics of the number of people entering and exiting the card reader is performed, but in a multi-region, due to the existence of an entrance and exit multi-card reader mode, the entrance and exit need to be calculated and added and subtracted respectively to obtain detailed and accurate statistical data. When the number of people is large, the number of areas is large, and the number of access boundaries is large, the mode and calculation need to uniformly calculate the information of people in all the areas and then calculate the leaving people in the areas.
The invention adopts the directional entrance guard authorization and entrance guard face rechecking authorization modes of the entrance guard, and combines the biological data rapid detection of an entrance guard management system and entrance guard face rechecking access control equipment to determine the number and data of people in the area. The access control system and the access control face which enter the region in a pointing mode recheck the authorization counting sum of the access control equipment, namely, the personnel in the region are counted quickly, and the region can be a designated region or a designated leaving region.
The regional personnel only carry out personnel information statistical calculation according to the region of the last authorization device entering the authorization region, namely the regional personnel are the personnel set of the last authorization information legally entered by all the authorization devices entering the region, namely the personnel information set of the region.
Total number of people in all regions:
For the statistics of the persons in the areas including, independent and leaving, the statistical calculation of the data conversion can also be carried out by adopting the scheme.
The personnel in the calculation area N can obtain the number of the personnel in the area by only calculating all legal authorization information pointing to the card reader in the boundary entering area N, and the system can count and summarize the data to obtain the number of the personnel in the area, simplify the calculation method for counting the personnel in the complex area, avoid the complex calculation of cumulative addition and subtraction of the number of the personnel in the area and the number of the personnel in the area, and simply, quickly and uniformly count the complex area and the simplified area.
The algorithm flow is as follows: and counting the authorization records of all the persons entering the face rechecking control equipment at last, wherein the area can be an entering area or an leaving area.
And taking out a rechecking control equipment set with directivity entering the area according to the area classification.
And performing intersection processing with the last authorized equipment record of all the statistical personnel and the regional classification equipment set.
And counting and obtaining the result, namely the personnel information set of the area.
