Description

{Manless Access Management System and Method for Shared Facility}

The present invention relates to a system for managing access to a shared facility such as a public office or public institution, and more particularly

A password is generated based on a specific function formula using time information as a variable, and when the set time elapses after password creation or the door is opened with the generated password, the password is automatically changed to invalidate the pre-generated password, and access to shared facilities A control circuit installed in the control circuit of the locking device that generates the same password as the user password generation program for each password generation time period based on the user password generation program installed in the user terminal when the application is accepted and the same function formula as the user password generation program By collating the generated passwords each generated in the password generation program, the locking device is opened or closed without mutual communication with the user terminal. It relates to an unmanned access management control system and management method for a shared facility that includes a function expression using time information as a variable to generate a password valid only within an allowable time period.

In general, auditoriums and conference rooms of public offices or public institutions are provided as shared facilities that are open to local residents and where various events and activities can be held. A dedicated management person will be deployed to close the entrance through the device and manage access to the shared facility.

However, depending on the purpose of the user's use, a shared facility can be accessed by a large number of people who do not have access qualifications, such as a public event, or can only be accessed by a specific user who is approved for reasons of confidentiality such as a technology development meeting or privacy protection such as holding a private event. There may be cases where access must be made.

As such, it is difficult to set access security due to the nature of multiple users and frequently changing users. It was necessary to introduce an unmanned management system for shared facilities, as there could be a loss of manpower in public offices or public institutions along with difficulties in organizing.

Due to the nature of the unmanned management system of shared facilities used by unspecified people, it is impossible to maintain the security of the shared facility by limiting the entrants through physical means such as biometric information such as fingerprint recognition or access security cards, etc. based access management system should be introduced.

However, passwords are easily leaked to the outside and are not secure enough to be used as a security measure for shared facilities used by an unspecified number of people. Inconvenience in management occurs, such as the facility manager having to change the password.

In order to solve this problem, in Republic of Korea Patent Publication No. 10-0445368 (Registered on August 12, 2004), a password that changes in real time is generated through a real-time password generator, and encrypted data is transmitted and received between the security device and the user authentication means. A door lock security device using a real-time password generator that authenticates users is proposed.

In addition, in Republic of Korea Patent Publication No. 10-1491706 (registered on February 3, 2015), authentication information is transmitted and received between a security application installed in a personal terminal and an access control device, and personal information of the personal terminal and personal information stored in the access control device are transmitted and received. We propose a method for providing an app-based access control service that opens the door when they match.

However, due to the nature of the shared facility that needs to be set by adjusting the level of security required for access according to the purpose of use of the user, the access security system as described above requires that each user who is permitted to use the shared facility have a limited use time and access conditions added individually. There is a problem in that it is difficult to build an unmanned access management control system for shared facilities.

In addition, when a communication failure occurs, the access control device cannot check whether the personal information of the user terminal matches, so the door may not be opened. It is necessary to compensate for the problem that the normal use of shared facility users is not achieved during time.

A control circuit 120 for controlling the opening or closing operation of the locking device 100 is formed by determining whether the input password matches.

The locking device 100 is mounted on the door 10 as shown in FIG. 2 and can be configured to lock while a latch operated by a rack and a pinion is caught in a latch groove formed in the doorway, and a rack and a pinion other than the rack and pinion. It can also be configured in a way of

When the password input by the user through the input unit 110 matches, the lock state is released as the latch and the latch groove are separated from each other, and the door 10 can be opened.

The password is a user password input by the user of the shared facility 1 through the input unit 110 of the locking device 100, and a control circuit password generated in the control circuit 120 shown in FIG. circuit password).

The user password is generated through the user password generation program (UPP), and the user password generation program (UPP) generates the password based on a specific function formula using time information as a variable. It is automatically changed and configured to invalidate the pre-generated password.

As shown in FIG. 4, the user password generation program (UPP) is stored in the server 200 accessible through the network, The user accesses the server 200 and is transmitted to the user terminal 400 such as a smart phone.

At this time, by opening the locking device 100 of the shared facility 1 only in the time period assigned to the user, the user password is generated to be stored in the server 200 to prevent illegal use of the shared facility 1 outside the permitted time period The program (UPP) will further include a function expression using time information for generating a password valid only within the time allowed for access to the shared facility 1 of the user as a variable.

In addition, the shared facility (1) manager separately stores each user password generation program (UPP) including time information of different shared facilities (1) access allowed time zones in a private access link, and stores the user password generation program (UPP) By individually disclosing the access link to the time sharing facility (1) access allower, a user who is not qualified to use the shared facility (1) in the corresponding time zone transmits the user password generation program (UPP) to the user terminal 400 it can be prevented

The control circuit password is generated through the control circuit password generation program (CPP) installed in the control circuit 120, and the control circuit password generation program (CPP) is a specific function formula using the same time information as the user password generation program (UPP) as a variable A password is generated based on the password, and when a set time elapses after the password is generated or when the door 10 is opened according to a match with the user input password, the password is automatically changed to invalidate the pre-generated password.

When the user of the shared facility (1) executes the user password generation program (UPP) installed in the user terminal 400 to unlock the locking device 100 and open the door 10, the user terminal 400 A user password is generated from the acquired time information, and when the user inputs the user password generated through the input unit 110 , the control circuit password generation program (CPP) installed in the control circuit 120 sends the password to the control circuit 120 . Since the control circuit password is generated from the time information obtained from the built-in or connected time device, the generated user password and the control circuit password have the same value.

At this time, the time for the user to generate the user password in the user password generation program (UPP) in order to unlock the lock state of the locking device 100 and the time when the control circuit password is generated in the control circuit password generation program (CPP) is the user terminal Since there is a difference between the process of checking the user password displayed on the output device of 400 and the time it takes to input the user password into the input unit 110, the user password and the control circuit password are changed for a preset period before and after creation. It should be set up so that it does not fail.

The user password and the control circuit password retention period are set in consideration of the time it takes for the user to input the user password into the input unit 110 after generating the user password, and when the password retention time elapses, the control circuit password is automatically changed and Invalidate user password and control circuit password.

In addition, if the retention time of the user password and the control circuit password elapses while the user inputs the user password through the input unit 110 , the pre-generated password is invalidated, and even if the user correctly inputs the pre-generated password, the locking device Inconvenience may occur in use in which the lock state of 100 is not released.

In the restricted transmission process (S41), when transmitting the user password generation program (UPP) to the user terminal 400, the user identification information identical to the user identification information input in the identification information submission step (S13) must be provided to prove the transmission qualification. And, the user identification information may include any one or more information selected from a mobile phone number, name, password, and the like.

If the user identification information provided by the user in the restricted transmission process (S41) matches the user identification information input in the identification information submission step (S13), the transmission of the user terminal 400 of the user password generation program (UPP) is completed, Transmission of the user password generation program (UPP) is limited only to users who have been approved by the administrator through the restriction on the transmission qualification of the user password generation program (UPP).

When the program distribution step (S40) proceeds by the applicant using the shared facility (1) selecting the automatic visitor application process (S12), the user applying for the shared facility (1) uses the user password generation program (UPP) from the server 200 A free transmission process ( S42 ) that can be freely transmitted to the user terminal 400 is performed.

In the free transmission process (S42), the user password generation program (UPP) is transmitted between fully disclosed or approved users or members of the user group so that an unspecified number can access the user password generation program (UPP) transmission link through the server 200 Restricted disclosure may be made that partially restricts access to the transport link through link sharing;

Whether the user password generation program (UPP) transmission link in the free transmission process (S42) is fully disclosed or limitedly disclosed may be configured so that the applicant can select it in the reservation step (S10) according to the purpose of using the shared facility (1) of the user applicant. have.

Shared facility (1) When the user's reservation for the use of the shared facility (1), the administrator's approval, and the user password generation program (UPP) are distributed, and the reservation time for the shared facility (1) arrives, the user can use the shared facility (1) ), the entrance to the shared facility door opening step (S50) in which the lock state of the locking device 100 of the door 10 can be released is completed.

In the step of opening and closing the shared facility door (S50), the user inputs the password generated by executing the user password generation program (UPP) to the input unit 110 of the lock device 100 installed on the door 10 of the shared facility 1, When the password generated in the control circuit 120 of the locking device 100 matches each other, the locking device 100 is released.

As shown in FIG. 8, the step (S50) of opening and closing the shared facility door is a user password generation process (S51) through a user password generation program (UPP), and a control circuit password generation process (S51) through a control circuit password generation program (CPP) ( S52), the password input process (S53) in which the user inputs the password through the input unit 110 of the locking device 100, and the lock state of the locking device through determining whether the password entered by the user matches the control circuit password It consists of a password determination process (S54) for determining whether to release.

In the user password generation process (S51), the user password generation program (UPP) installed in the user terminal 400 is executed to generate a user password consisting of a plurality of numbers or strings by a function expression using time information as a variable.

In the control circuit password generation process (S52), the control circuit password generation program (CPP) installed in the control circuit 120 is executed by the user recognition of the control circuit 120 to generate the control circuit password, and the control circuit password generation program ( CPP) includes a function expression that uses the same time information as the user password generation program (UPP) as a variable to form a control circuit password consisting of a plurality of numbers or strings identical to the user password generated in the user password generation process (S51). do.

The user recognition of the control circuit 120 in the control circuit password generation process (S52) may be made in the process of the user pressing a password input key or a separate button through the input unit 110 in the password input process (S53), the user password The generation process (S51), the control circuit password generation process (S52), and the password input process (S53) may be performed in parallel or by changing the order.

The user password generated in the user password generation process (S51) is automatically changed when a preset specific time elapses to invalidate the pre-generated password, and the control circuit password generated in the control circuit password generation process (S52) is a preset specific password. When time elapses, it is automatically changed and the pre-generated password is invalidated.

In addition, in order to prevent unauthorized access to the shared facility (1) by leaking the password to those who are not permitted to access the shared facility (1), use the control circuit password generated in the control circuit password generation process (S52) to 10) When opening is made, the control circuit password is automatically changed regardless of whether the automatic change setting time of the control circuit password has arrived, and is configured to invalidate the pre-generated control circuit password.

At this time, the user password and the control circuit password generated in the user password generation process (S51) and the control circuit password generation process (S52) are the user password generation program (UPP) in the user terminal 400 in the user password generation process (S51) ), and after generating the user password in the user password generation program (UPP), the user inputs the password through the input unit 110 in the password input process (S53), and the control circuit 120 generates the control circuit password generation program A difference in creation time occurs as much as the time required to execute (CPP).

Due to the nature of the user password and the control circuit password whose password is changed in real time by a function formula based on time information, if there is a difference in the password generation time, the generated user password and the control circuit password may be different. In the password generation function of the generation program (UPP) and the control circuit password generation program (CPP), the password is kept constant for a preset time before and after the password generation time, thereby securing sufficient time for the user password and the control circuit password to overlap each other. It can contain commands that can do it.

In the process of the user running the user password generation program (UPP) to generate the user password, and inputting the password generated through the input unit 110 of the locking device 100, the automatic change setting time of the control circuit password arrives. If the retention time of the control circuit password elapses, even if the user correctly inputs the pre-generated password, it may cause inconvenience in using that the lock state of the locking device 100 is not released due to invalidation of the pre-generated password. In the process (S53), in the password input state through the input unit 110, a command for temporarily blocking the automatic change of the control circuit password may be included.

In the password determination process (S54), the password input in the password input process (S53) and the control circuit password generated in the control circuit password generation process (S52) are compared to determine whether both passwords match, and the control circuit password and the user input When the passwords match, the locking state of the locking device 100 is released, and if the control circuit password and the user input password do not match or the password is not entered within the set time, the locking state of the locking device 100 is maintained.

Lock for determining whether the password matches the password by the control circuit 120 in the password generation process (S51) or the password creation process (S52) of the shared facility door opening and closing step (S50) or the password generation process (S54) in the password determination process (S54) A detailed example for configuring the control circuit 120 of the device 100 is as follows.

A user password or control circuit password formation function whose password is changed according to the creation time can be configured as shown in the Arduino grammar below.

int hour = time.hour;

int day = time.date;

int month = time.mon;

char* secretCode = t secretCode(hour,day,month);

char* t secretCode(int a,int b,int c){

int y = 0;

long m=func(a,b,c) // Create password function

//Serial.println(m);

//delay(1000);

y=m%10000; // make 4 digits

if(y<1000){

y = y+1000; // If less than 4 digits, make it 4 digits

}

//Serial.println(y);

//delay(1000);

String t pass = String(y);

t pass.toCharArray(Code,5);

return Code;

}

The Arduino grammar obtains the values of month, day, and time through the time, hour/time.date/tme.mon function that is changed according to time, and the shared facility (1) user accesses the door (1) through an undisclosed function expression. When the user password generation program (UPP) or control circuit password generation program (CPP) is executed for opening, a password that changes according to time is generated and updated every set time.

The above command is an example for generating a 4-digit password, and in consideration of security and ease of use, the number of digits of the password may increase or decrease according to the setting of the administrator. can be set.

In the password determination process (S54), the function of unlocking the lock state of the locking device 100 according to the match between the two passwords and the function of initializing the control circuit password when an incorrect password is input can be configured and implemented as shown in the Arduino grammar below.

bool check password(char*a,char*b,int n){

int check = 0;

for(int i = 0; i<n; i++){

if(a[i]==b[i]){

check+ = 1;

}

}

//Serial.println(check);

if(check==n){

return true;

}

else {

return false;

}

}

The command shows an example in which the control circuit password generation process (S52) starts when the user presses the * key of the input unit 110, and when the user presses the * key of the input unit 110, the control circuit password generation program (CPP) is executed, After the user inputs the password string through the input unit 110 and presses the * key again, the check password function determines whether the password entered by the user is the same as the control circuit password to unlock the locking device 100 will do

At this time, when the user inputs a password through the input unit 110, a special character corresponding to the number of input password digits is displayed on the screen provided on the lock device 100 so as to check whether the password input is properly performed, or the Arduino grammar and Similarly, when a password is input through a speaker provided in the locking device 100, a sound can be generated by placing a voltage difference between the + pole pin and the - pole pin.

if(key){

password[position] = key;

position = position+1;

buzz(3000);

Serial.println(key);

}

When the user who opened the door 10 in the shared facility door opening step (S50) enters the shared facility 1 internal space and the door 10 is closed, the door 10 is locked by the operation of the locking device 100 By setting the control circuit 120, it can be configured to prevent a person who does not have suitable access qualifications to enter the shared facility (1).

As shown in the Arduino grammar below, if the latch of the locking device 100 is pressed for more than 2 seconds when the automatic locking function of the locking device 100 is set, the door 10 is automatically locked, and the purpose of use of the shared facility (1) If the access security level is lowered so that anyone can enter without limiting the user's qualifications, the automatic locking function of the locking device 100 is released and the door 10 is not automatically locked even if the latch of the locking device 100 is pressed for more than 2 seconds. won't

When the shared facility door opening step (S50) is completed, the shared facility (1) user will use the shared facility (1) for the permitted shared facility (1) usage time, and the user's shared facility ( 1) A sensor 500 of a thermal sensing method capable of distinguishing the entrance and exit directions may be installed, and the control circuit 120 may be configured to detect a user's entry and exit in the shared facility 1 .

The sensor 500 counts the number of users entering and exiting the shared facility 1 during the permitted period of use, and the aggregated number of simultaneous entrances in the shared facility 1 is requested in the shared facility 1 reservation step (S10). If the number of allowed access is exceeded, the result of illegal use of the sharing facility 1 is displayed on at least one of the user terminal 400 and the manager terminal 300 .

In addition, as the password entered by the user and the control circuit password in the password determination process (S54) of the shared facility door opening and closing step (S50) match each other, only when the lock state of the locking device 100 is legally released It may be configured to turn off the power of the electrical facility 700 .

When the sensor 500 detects the motion of the first user entering the shared facility (1) internal space, the control circuit 120 automatically applies power to the internal lighting and electrical facilities 700 of the shared facility (1) and , when the sensor 500 detects the motion of the end user leaving the shared facility 1, the control circuit 120 turns off the power of the lighting and electrical facilities 700 inside the shared facility 1, permitting use It prevents the use of the shared facility (1) in an illegal way outside of the designated hours.

And, when the sensor 500 detects that the user is illegally using the shared facility 1 after the permitted use time of the shared facility 1 has elapsed, an alarm generating process for displaying the elapsed usage time to the manager and the user (S55) may proceed.

In addition, after the alarm generation process (S55) according to the use of the shared facility (1) exceeding the usage time, the sensor 500 detects that the warning notified through the user terminal 400 is ignored and the shared facility 1 continues to be used When a certain period of time has elapsed from the time when the time elapsed fact is displayed, the power of the internal lighting and electrical facilities 700 of the shared facility 1 is automatically turned off, or the internal lighting of the shared facility 1 is controlled by the manager's remote control. And a forced termination process (S52) in which the power of the electrical facility 700 is manually released may be added.

Due to the nature of the control system and management method of the present invention in which the access control of the shared facility (1) user is unattended, even if the illegal use is made beyond the shared facility (1) usage time, the shared facility (1) illegal user has immediate exit measures can be difficult to achieve.

Therefore, by adding the forced termination process ( S52 ) to the alarm generating process ( S55 ), it is possible to prevent inconvenience such as a decrease in the use time of the next-time sharing facility ( 1 ) reservation user by indirectly forcing the illegal user to leave.

When the user's use of the shared facility (1) is completed, the manager evaluates the suitability of using the shared facility (1) by checking the number of people requested at the time of reservation to use the shared facility (1) or whether there is any illegal use that violates the usage time conditions and an evaluation step (S60) of recording the evaluation result in the manager terminal 300 may be performed.

The manager evaluation result made in the evaluation step (S60) is reflected in the reservation approval step (S20) made when the user makes a reservation for use of the next shared facility (1), and can be used when determining permission to use the next shared facility (1), through this By blocking the use of the shared facility (1) for unsuitable users, the maintenance and management of the shared facility (1) can be made easier.

In addition, the sensor 500 is interlocked with the control circuit 120 and the photographing device 600 installed inside the shared facility 1, and after the locking state of the locking device 100 is released in the step (S50) of the shared facility door opening and closing step (S50) , when the first user's entry into the shared facility 1 is detected through the sensor 500, the first photographing of the inner space of the shared facility 1 is made, and when detecting the motion of the end user leaving the shared facility 1 The shared facility 1 may be configured to take a secondary photograph of the internal space.

The manager can view the first and second photographed images taken through the photographing device 600 to determine whether the appropriate use of the shared facility 1 has been made, and the determination result is reflected in the next reservation approval step (S20) and the photographed images before and after use of the shared facility (1) can be used as data and evidence for determining who is responsible in the event of damage or theft of furniture in the shared facility (1).

At this time, the first and second shooting through the photographing device 600 is only when it is confirmed that the shared facility 1 is in an unattended state by the operation of the sensor 500. Facility (1) It should be possible to prevent invasion of users' privacy or leakage of confidential information.

In addition, when the sensor 500 detects that the temperature inside the shared facility 1 rises above the set value, it is determined that a fire has occurred and the control circuit 120 may be configured to operate the fire alarm device 800 , , the sensor 500 and the fire alarm device 800 are configured to be operated at all times regardless of whether the user uses the inside of the shared facility 1 .
