when the face information recognized by the face recognition unit I is matched with the face information and the identity information stored in the storage database, the inbound gate is opened, the data updating unit stores the newly acquired face information in the block chain, and replaces and updates historical face information stored in the block chain in an occupied mode;

when the face information identified by the first face identification unit is not matched with the face information and the identity information stored in the storage database, the information comparison unit matches the face information identified by the first face identification unit with the face information of the person who loses credit uploaded by the person who loses credit uploading unit;

after the information comparison unit compares the information, the central control unit judges the information as a person who loses confidence, and the alarm reminding unit reminds the worker of solving the problem in the future;

after the information comparison unit compares the information, the central control unit judges that the person is not a person who loses confidence, and the subtitle reminding unit reminds the passenger to carry out identity information authentication by using an identity card.

The information comparison unit is also used for matching the face information identified by the face identification unit II with the face information of the outbound personnel;

after the information comparison unit compares the information, the central control unit judges the information as a malicious ticket evasion person, and the alarm reminding unit reminds the staff of solving the problem in the future and assists the passenger in supplementing the ticket;

after the information comparison unit compares the information, the central control unit judges that the passenger does not escape, and the passenger automatically passes through the exit.

Through the face recognition of the exit, the occurrence of malicious ticket evasion can be greatly reduced, and the stability of social order is facilitated.

The first embodiment is as follows: the ticket purchasing information uploading unit uploads the ticket purchasing information of the passenger to the central processing unit, wherein the ticket purchasing information comprises departure time t which is 10:00 and the destination of the passenger is Nanjing city;

the data calling unit calls the historical riding and departure time from the block chain to form a historical riding and departure time set t_Collection＝{t₁，t₂，t₃，...，t_n10: 20,9: 25,2: 30, 12: 05, 10: 20, the data calling unit calls historical inbound time from the block chain to form a historical inbound time set T_Collection＝{T₁，T₂，T₃，...，T_n{ 9: 30,8: 50,1: 55, 11: 30, 10: 05}, wherein, T₁，T₂，T₃，...，T_nAnd respectively representing the station-entering time of n times of riding, wherein the station-entering time is determined by the recognition time of the face recognition unit I.

The data analysis unit calculates the difference between the time of each arrival and the departure time of the passenger according to the following formula:

P₁＝t₁-T₁＝50；

P₂＝t₂-T₂＝35；

P₃＝t₃-T₃＝35；

P₄＝t₄-T₄＝35；

P₅＝t₅-T₅＝15；

set P of differences between arrival time and departure time of 5 passenger rides_Collection＝{P₁，P₂，P₃，...，P_n50, 35, 35, 15, where P₁，P₂，P₃，...，P_nRespectively representing the difference between the arrival time and departure time of the passengers taking n times of cars;

removing the set P according to the following formula_CollectionMaximum and minimum values of;

；

wherein the content of the first and second substances,representation set P_CollectionThe difference between any two values;

when in useWhen it is, take P_iAnd P_kP in (1)_iStoring as a tentative maximum in the set M, taking P_iAnd P_kP in (1)_kStoring the value as a tentative minimum value into a set N;

when in useWhen it is, take P_iAnd P_kP in (1)_kStoring as a tentative maximum in the set M, taking P_iAnd P_kP in (1)_iStoring the value as a tentative minimum value into a set N;

repeating the calculation according to the formula, and confirming the maximum value P of the difference value between the arrival time and departure time of 5 times of riding from the maximum value set M_maxConfirming the minimum value P of the difference between the arrival time and departure time of 5 times of riding from the minimum value set N as 50_min15, the maximum value P of the difference between the arrival time and departure time of 5 times of riding_maxAnd the minimum value P of the difference between the arrival time and departure time of 5 times of riding_minFrom the set P_CollectionRemoving to form a set P of difference values between 3 times of taking bus of passengers and departure time_{New collection}＝{P₁，P₂，P₃，...，P_n-2And {35, 35, 35}, by removing the maximum value and the minimum value between the arrival time and the riding time, accidents can be eliminated, so that the prediction of the arrival time of the passenger is more accurate, and the time point of the data calling unit calling the passenger face information is more timely.

The data analysis unit analyzes the arrival time of the passenger at the time according to the historical big data:

the difference between the arrival time and departure time of the passenger at this time is calculated according to the following formula:

；

wherein, P_T35 represents the difference between the arrival time and the riding time; for passengers according to the following formula

The time of this arrival is calculated:

T＝t-P_T＝9：25；

where T-9: 25 indicates the time when the passenger enters the station this time.

Through the prediction of the station-entering time of the passengers, the face information and the identity information of the passengers can be called from the block chain in advance and stored in the storage database, the phenomenon that the face information and the identity information of the passengers are called too late to increase the short-time calculation amount of the system is avoided, the calculation pressure of the system is reduced, meanwhile, the phenomenon that the face information and the identity information of the passengers are called too early to cause more face information and identity information to be stored in the storage database is avoided, the effect of reducing the calculation pressure of the system cannot be achieved, and through the prediction of the station-entering time of the passengers, the face information and the identity information of the passengers are stored in the storage database in different time intervals, the calculation pressure of the system is dispersed, and the station-entering efficiency is greatly improved.

The data calling unit calls and stores the face information and the identity information stored in the block chain in a storage database within a time period T +/-a being 9:25 +/-5, and the information comparison unit compares the face information recognized by the first face recognition unit with the face information and the identity information in the storage database.
