3. The method as claimed in claim 2, wherein the application of the visitor face identification information to the area within the cell and the area outside the cell exit further comprises the following control methods:
the second face information is used for obtaining face identification information in the current cell position, comparing the current first face identification information, removing repeated identical face identification information, and judging whether the current access time td1 of current unrepeated visitor information exceeds a preset value, wherein the preset value is the time calculated by the distance from a current visitor to a building, and if the current access time exceeds the access time, the current visitor access authority is adjusted to be a second authority;
obtaining the position information of a positioning card in the current visitor, obtaining the current distance from a district entrance guard, calculating the use time Td2 of a second permission according to the distance, and adjusting the third permission of the current visitor if the visitor exceeds the use time of the second permission, wherein the third permission cannot enter or exit all buildings in the district and send information to remind the visitor to leave the district as soon as possible;
and the community exit entrance guard acquires fourth face identification information, calls the permission level of the current visitor from the current upper computer SQL database, normally releases the visitor when the permission level is the first permission level or the second permission level, and shoots, files and encodes the current visitor into a blacklist and then carries out the direction if the permission level of the current visitor is the third permission level.
4. The method as claimed in claim 1, wherein the authority positioning card is connected to a WiFi coverage area, and sends the visitor's position to the upper computer in real time, wherein the planning time of the first authority and the second authority of the route in the area further comprises the following calculation methods;
acquiring a first right in a target cell entrance guard, acquiring a distance between a current visitor and a target building to be accessed, allocating a first right use time Td1 according to the current distance, wherein Td1= (the current access building distance/the normal walking speed) × 1.5, and allocating a monitoring weight X = T/Td1 (T =1,2,3.. cndot.) wherein T increases along with the decrease of the Td 1;
when the visitor monitoring weight X is infinite, the access right of the current visitor is converted, the current visitor is adjusted to be the second right, and the second right time is recalculated, wherein if the current visitor is within the range of the cell, the second right use time Td2 of the current visitor is acquired again, wherein Td2= ((current access building distance-current position of the visitor and entrance guard distance of the cell)/normal walking speed) × 1.5;
and after the second permission service time is timed, whether the positioning permission card is returned or not is obtained again, if the positioning permission card is not returned, the visitor is reset to be a third permission, and the visitor is positioned and sent to a security place and then is reminded to leave the target cell as soon as possible.
5. The method as claimed in claim 1, wherein the step of obtaining the identity information of the faces in the building and the step of repeatedly recognizing the face recognition information at the entrance give the first right time again, and monitoring the first right time, wherein the step of distributing the time and monitoring the time further comprises the following steps:
when the face identification information acquired in the building door is consistent with the face identification information at the entrance of the cell, acquiring the current first permission use time Td1 of the visitor, calculating the used permission time Tsd1, acquiring the floor S visited by the visitor, and reallocating the first permission time T according to the access floor and the used permission time T = (S:averagefloor height X/average walking speed) + Td1-Tsd1, wherein X is a random value (2, 3,4.. N), and X is reduced along with the increase of the number of floors;
assigning a monitoring weight according to the visitor first permission time, X1= T/T (T =1,2,3.. once.n), wherein T is increased along with the decrease of the first permission time T, when the first permission time monitoring weight is infinite, the positioning permission card is signaled, and the assignment is carried out again along with a second permission time Td2, wherein Td2= the current access building distance X/walking speed, wherein X is a random value (2, 3,4.. once.n), and X is decreased along with the increase of the number of accessed floors;
when the second permission time is started, reassigning a monitoring weight X2= ((S X T)/(S1 Td 2)) -T (T =1,2,3.. n) of the second permission time, wherein S is a current access building distance, S1 is a distance between the positioning permission card and a cell exit, and a timing time T, T, at which the second permission starts, is increased along with the decrease of the second permission time Td 2;
and when the second monitoring weight reaches a preset value, adjusting the second permission time of the visitor to be changed into a third permission time, and sending visitor position information to a security room, wherein the preset value is that when the monitoring weight of the second permission time is infinite, or S1 exceeds S and reaches a certain distance, the judgment is abnormal.
6. A method as claimed in claim 1, wherein when the visitor locates the permission card at the third level, a timer Ts1 is reset, and when the Ts1 exceeds the preset value, a message value security room is sent to notify security, wherein the Ts1 is adjusted according to the purpose of the visitor's place.
