The method of realizing unique numbering of seats is: numbering the building where the library and study room are located, numbering the floors of the building, numbering the classrooms on the floors, numbering the seats in the classrooms, and realizing each The unique identification number of each seat is stored in the background data system. The background reservation system and seat usage management system apply to the background data system to access the corresponding seat and use the unique identification number of each seat.

The method to achieve a uniquely determined number for a user is: when a user registers an account, he needs to use his or her student number or faculty number to realize the uniquely determined number of the user, which is stored in the background data system, and can be used when logging in, making an appointment, or breaching a contract. When recording, the intelligent library system setting system will use the number uniquely determined by the user to record the user's behavior.

The method of setting user authority levels for the intelligent library system is as follows: setting different user authority levels in the background data system, including ordinary users, system administrators, system senior administrators, and super administrators.

The ordinary user has the following rights: rights to query information on available seats, rights to reserve seats, rights to cancel reservations, rights to view their own default records, and rights to view system announcements.

The system administrator has the following rights: all rights of ordinary users, rights to manage the background reservation management system, and rights to manage the seat usage management system. When managing the reservation management system in the background, there are permissions to set the seats that are allowed to be reserved, the authority to set the time period for allowing reservations, the authority to set the time for canceling reservations, and the authority to publish system announcements.

The method of encryption, protection and authentication of transmitted data is as follows: the network server system provides data encryption and authentication, the key distribution center in the network server system performs key distribution, and all users are added to the key during registration. The distribution center management library, unified management of keys, unified identity authentication, through public key encryption and private key encryption, using hash function, RC4 algorithm to encrypt the data transmitted in the network, and verify the identity of the originator, to prevent the Eavesdropping or stealing by others.

The method of transparent access to the background data system is: the background data system is built on the network server system and can only be accessed through the network server system. Other subsystems must use the network server system as a middleman when accessing the background data system. During the actual access, the access details are hidden from other subsystems. Just directly initiate a request to access the background data system, and the web server system will automatically obtain all the access requests, and perform authority management and identity authentication on the requests. Only through the web server Only requests for system authentication can be submitted to the background data system.

In the present invention, as shown in Figure 2, the hierarchical structure of the intelligent library and the study room seat monitoring system is as follows:

The background data system is at layer 0, as the bottom layer of the system, storing all data. The functions responsible for layer 0 include data storage, data protection, and data update. In layer 0, data is stored through distributed storage, and different data are classified into permissions, and data operations are restricted. All data requests entering layer 0 are carried out in accordance with strict database permissions, and only data requests that meet the permissions will be executed. . Due to the transparent access mechanism of layer 1, requests entering layer 0 are all controllable, thereby increasing the data security system.

The network server system is in layer 1, which is the interaction layer between layer 0 (background data system) and high-level data, and is used to control the transmission of all data, including data encryption, data authentication, network data communication mode setting and transparent access. Layer 0 sets the communication mode between Layer 3 and Layer 2, and unifies the data transmission format. For data transmitted through the mobile Internet, a unified key encryption mode and hash algorithm will be determined to prevent data eavesdropping and data duplication. put. Layer 0 adds an authentication code to the data obtained by layer 2 transmission, and adds an encrypted identity code at the end of the data string to authenticate the device sending the request. The data requests sent by the subsystems of layer 2 are all directed to layer 0, and layer 1 monitors layer 2. Before the request of layer 2 reaches layer 0, layer 0 will intercept and verify each request to achieve transparency. access.

The seat usage management system and the background reservation management system are on the second floor. As the realization layer of the system functions, the incoming data is processed, and the corresponding requests are sent according to the incoming data to realize the functions of the system. Among them, the realized system functions include: in the seat usage management system, dynamic monitoring of all seat usage, judgment of reserved seat usage, record of illegal seat occupation behavior, setting of seat monitoring mode and setting of seat vacancy mode ;In the background reservation management system, all users' registration, login, logout, logout and permission settings, ordinary users' seat query, seat reservation, cancellation of seat reservation, default record query and announcement query, system administrator's seat reservation and The setting of the available time and the modification of the number of seats for the system administrator. The layer 3 subsystem sends the request data to realize the system function to the corresponding subsystems of the second layer. When the corresponding subsystems of the second layer receive the request data and related information data, the request data will be analyzed. Generate corresponding function request information, send the function request information to layer 0 through layer 1, obtain the execution result data of layer 0, combine the relevant information data sent by layer 3 and the execution result data of layer 0, analyze and calculate the function Execution result data, send the request that needs to be written to layer 0 in the function execution result data to layer 0. If layer 0 returns execution success data, layer 2 determines that the execution is successful, and sends the function execution result data to layer 3. The layer presents the results to the user.

The face recognition access control security system, seat temporary leave system, seat use monitoring system, and intelligent reservation terminal are located on the 3rd floor. As the input layer of the system, it is responsible for reading all the data required by the system and displaying the interface of the system. After reading the data It is transmitted to layer 2 for processing, and the display mode is refreshed according to the incoming data of layer 2. In the present invention, the input data types include: account, password, personal identity information, face recognition picture information, seat reservation request information, query request information for seat reservation record, and request information for canceling seat reservation input by the user in the intelligent reservation terminal , query the request information for violation records, view the request information for announcements, and request information for logging out; the request information for updating the local face recognition image database sent from the face recognition access control security system, the record information for personnel illegal entry and the record information for personnel entry; seat use The information on the judgment result of whether there is a person in the seat monitored by the monitoring system; the information on the usage of the temporary leave button detected in the seat temporary leave system. The input data will be sent to the corresponding system in layer 2, and the result data passed in in layer 2 will be used for display to the user.

The present invention separates the data storage, data transmission, data processing, and data input of the system through the above-mentioned four-layer structure, and only the corresponding part needs to be modified by the super administrator when the system function is modified.

Users, system administrators and system senior administrators register through the intelligent reservation terminal, and send a registration request to the background reservation management system. After receiving the registration request, the background reservation management system sends a read data request to the background data system. The network server As soon as the system intercepts the read data request, it performs verification. After the verification is successful, it sends the read data request to the background data system, and processes the returned data from the background data system and sends it to the background reservation management system. The background reservation management system returns The data is processed to judge the registration success or the registration failure. When the registration fails, failure data is sent to the intelligent reservation terminal, and the reservation-capable terminal displays the result. When the registration is successful, a write request to write a registered account information is sent to the background data system. The network server system intercepts the write request and verifies it. After the verification is successful, it is sent to the background data system, and the execution result of the background data system is sent to the background data system. It is sent to the background reservation management system. When the execution is successful, it is determined that the registration is completed, and success data is sent to the reservation terminal, and the reservation-capable terminal displays the result. When registering, the student number or job number and ID number will be verified as the unique number, and the verified personal information and face recognition picture information will be stored in the background data system.

After registration, ordinary users can log in with the account and password through the reservation terminal. After logging in, they can perform seat inquiry, seat reservation, cancellation reservation, default record inquiry, and announcement viewing operations according to the user interface. The data processing flow of these operations is the same as the data processing flow of user registration, and the differences between the operations are: the data required to be input by the intelligent reservation terminal is different, and the calculation process of the background reservation management system is different. When performing the login operation, the background reservation management system will verify whether the entered account and password are correct. When performing seat query, the background reservation management system will query the real-time seat usage information, open reservation seat information, and open reservation seat authority information. When performing a seat reservation operation, the background reservation management system will verify whether the open seat reservation authority information, user authority information, and the user's reserved seat information meet the reservation conditions. When canceling the reservation, the background reservation management system will verify that the user has reserved a seat. Information and seats allow cancellation of reservation time data whether the data meets the conditions for cancellation of reservation. When performing the default record query operation, the background reservation management system will query the default record information, and when performing the check announcement operation, the background reservation management system will query the announcement information.

After the user completes the seat reservation, a corresponding user seat reservation record will be stored in the background data system. When the face recognition access control security system performs the operation of updating the local face recognition database, it will send the request information to update the local face recognition picture database to the background data system, including a request information for querying the current classroom reservation record and a request information for reading this classroom The request information for the face recognition picture of the reserved person. The former request information is used to obtain the list of people allowed to enter the classroom, and the latter information is used to obtain the face recognition picture information of the people allowed to enter the classroom, and update the local face Identifying the picture database, this operation ensures that every person who has reserved a seat in the classroom can enter the classroom through the access control machine, and prevent other people from entering. When a person is close to the door, the human body infrared sensor detector will detect it, the face recognition camera will be activated, and the person will be recognized. Users who have made reservations can enter smoothly, while users who have not made reservations will be blocked outside the classroom by the access control machine, and will be prompted by the voice broadcast prompter. If people enter illegally, the alarm will be activated to prompt the management personnel.

_The seat usage detection system is used to detect seat usage. If the seat has not been reserved and no _one is using it, it will be detected every T1 time. The seat usage management system sends the results. If the seat has not been reserved and is used, it will be detected every T ₂ time. If it is detected that the seat is unoccupied for N ₂ consecutive times, it will be determined that the seat has not been used, and the result will be sent to the seat usage management system. If the seat is reserved and no one is using it, it will check every T ₃ time. If the seat is detected for N ₃ consecutive times, it is determined that the reserved user has taken the seat, and the result is sent to the seat usage management system. If the seat is reserved and it is used, it will be detected every T4 time _{. If it is detected that the seat is unoccupied for N 4 consecutive} times, it will be determined that the reserved user has left the seat, and the result will be sent to the seat usage management system. The detection times T ₁ , T ₂ , T ₃ , T ₄ and the detection times N ₁ , N ₂ , N ₃ , and N ₄ of the seat usage detection system are determined when the seat usage management system sets the detection mode.

The seat leave system is used to meet the user's need to temporarily leave the seat. If the user is using a certain seat, if the user does not need to temporarily leave the seat for a period of time, but wants to keep the seat, the user can use the seat temporary leave system. The seat leave button, when the seat leave button is used, the seat leave display will light up, indicating that the seat is in a temporary leave state. At this time, the seat use monitoring system detects that the seat is not in use, and the seat use management system will The seat status is updated to temporarily leave. If the user does not return to the seat after T ₅ time, it is determined that the user has not violated the seat occupation behavior, and a violation message is added, and the seat status is updated to unoccupied. If the user returns to the seat within the time _T5 , it is determined that the user is using it normally, and at the same time, the user is prohibited from using the temporary leave button again within the time when the user returns to the seat _T6 . The monitoring times T ₅ and T ₆ of the seat temporarily leaving system are determined when the seat usage management system sets the temporary leaving mode.

When the user reserves a seat and fails to cancel the reservation within the specified time, if the user does not arrive at the reserved seat within the specified time _T7 , the seat usage management system determines that the user has not used the seat over time, and determines that it is a violation of seat occupation. Violation information, and update the seat status as unoccupied.

The above are only the preferred embodiments of the present invention.
