The present invention relates to an electronic key management system. More specifically, in using the electronic key as a master key, if the data code received from the electronic key in the electronic lock device matches or updates the preset code, the received data code is stored without going through a separate registration procedure. The present invention relates to an electronic key operation system capable of unlocking a lock.

Conventionally used electronic lock device is a device that performs the function of unlocking the lock device when authentication is successful by comparing with the electronic key ID or password set after receiving the electronic key or password, a kind of digital door (Digital Door -Lock) means the device.

Where multi-family houses such as apartments or officetels live together, the same electronic lock is installed at the time of construction, and a master key can be unlocked by the on-site manager for each furniture to ensure smooth management of the apartment and officetel during the installation process. Will have.

In other words, for example, the construction site of an apartment or officetel, usually an electronic lock (digital door lock device) is installed at the beginning of the internal construction, the site manager makes a master key until the interior construction is completed To manage the generation.

In the conventional method, the electronic key is used as the master key. In the construction site, the master site is divided into an entire master key capable of managing the entire site and a partition master key divided by apartment buildings or entrance doors.

The total master key and the partition master key are made by the required number of managers and workers, and the site manager who manages the overall work uses the whole master key, and the workers perform the work using the partition master key.

An electronic lock device is a device that unlocks or locks a device by registering an electronic key ID or password. Due to the limitation of memory capacity, an electronic lock device can register about 10 electronic key IDs. Only ID is registered and used. Here, the number of registration of the electronic key ID may increase according to the memory capacity of the electronic lock device, but the number is limited due to the limitation of the capacity of the memory. That is, if it is assumed that the electronic lock device can register 10 electronic key IDs, the total master key and the partition master key cannot be made more than 10.

In the conventional method of using an electronic key as a master key, after grasping the quantity of the electronic locking device installed in each furniture, the master key is produced. For example, if an apartment construction site assumes a total of 1000 households (five buildings), five total master keys are needed, and five parcel master keys are required, each installed in 1000 households. Each master's electronic lock must register five master keys manually, and five compartment master keys must be registered for each electronic lock installed in each building of 1000 households.

If one of the master keys of the entire master key or the partition master key used in the conventional method using the electronic key as the master key is lost, the operation of deleting the ID of the lost master key from 1000 households is added. There is a disadvantage that the ID of all the electronic keys, that is, master keys remaining after the loss, must be registered again.

For example, if one of the five master keys is lost, the conventional site manager adds one new master key and visits every 1000 households to delete the lost master key. After all, all five master keys used were registered with the electronic lock. That is, since 1000 × 5 = 5000, there is a hassle to register the entire master key 5000 times.

On the other hand, when looking at the method of using a password as a master key of the conventional method, there is a method of randomly assigning a password to be used in all 1000 households stored as a document, but these methods also need to register a password corresponding to 1000 households one by one There was a downside.

In addition, the site manager updates the new password every day in order to prevent the leakage of the password after notifying the operator of the password, and the update process of such a password also has the disadvantage of registering the password manually, and all generation passwords are managed as documents. Therefore, the security of the password is high and the security is inferior, and unless all the passwords of 1000 households are designated as the same password, there is a disadvantage that the entire household cannot be managed with one password.

On the other hand, among the conventional methods, the administrator or operator can register a random password and electronic key by pressing the registration button can be easily used by anyone, and no separate approval procedure is required, but the site administrator can integrate the password set by the operator as a whole. It is difficult to manage, and there is a disadvantage in that the electronic lock device cannot be released if the operator loses a randomly set password and electronic key. In other words, in order to release the electronic lock, the worker must enter the window in a row.

Therefore, it is possible to restrict the authority to change the electronic key ID or password and to provide an electronic key operation system that can be used as an integrated master key concept without registering the electronic key ID or password in the electronic lock device. Until now, such an electronic key operation system is not provided.

In order to solve the above-mentioned problems, the present invention, in using the electronic key as a master key, if the data code received from the electronic key in the electronic lock device is a code matching or updated code, without going through a separate registration process An object of the present invention is to provide an electronic key operation system capable of unlocking a stored data code.

In order to achieve the above object, the present invention, in the electronic key operation system, the data corresponding to the master code (Master Code) in which data corresponding to a valid code is recorded and the unique value for distinguishing the version of the electronic key is recorded A master key having a storage unit including a level code; And receiving the master code and, if the master code is the valid code, receiving the level code and checking whether the level code has been updated, and unlocking the lock when the level code is updated. Provide a lock.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

3 is an exemplary view showing a data code of a master key according to a preferred embodiment of the present invention.

The master key 120 according to the preferred embodiment of the present invention includes the master code 330 and the level code 350 as essential components, and additionally, the function code 310, the site code 320 and the block code 340. ) At least one data code.

Master key 120 according to a preferred embodiment of the present invention may be configured to include only the master code 330 and the level code 350 in a single apartment complex or a single compartment, a function in a plurality of apartment complexes or a plurality of compartments It is configured to include one or more data codes of the code 310, the site code 320 and the block code 340.

The function code 310 is a data code including at least one of master key data, setting key data, and test key data, and determines a type of an electronic key.

That is, when the electronic key in which the master key data is inserted into the function code 310 is inserted into the electronic locking device 110, the electronic locking device 110 recognizes the electronic key as the master key. When the electronic key in which the setting key data is inserted into the electronic lock device 110 is inserted into the electronic lock device 110, the electronic lock device 110 recognizes the electronic key as the setting key, and the test key data is inserted into the function code 310. When the electronic key is inserted into the electronic lock 110, the electronic lock 110 recognizes the electronic key as a test key, but in the present invention, it is assumed that the master key data is inserted into the function code 310 for convenience of description. Explain.

The site code 320 is a data code corresponding to the serial number specified by the key issuer 130 and is a data code for distinguishing a construction site, an apartment complex, or an officetel complex.

For example, when the site code of the apartment complex A is 1234 and the site code of the apartment apartment B is 5678, when the site code 320 of the master key is designated as 1234 by the key issuer 130, the master key 120 Is recognized as the master key in apartment A and not as the master key in apartment B.

That is, the site code 320 is data corresponding to a serial number for classifying by site such as an apartment complex or an officetel complex, and is an additional component that may not be used in a single apartment complex.

The master code 330 records data for determining whether the electronic key is a valid key. That is, the master code 330 is a value programmatically assigned data according to a predetermined rule, and the electronic lock device 110 receives the master code 330 and compares it with a preset condition to determine whether it is a valid code. It is.

For example, if it is assumed that the preset condition for the master code 330 is a condition that the master code 330 is all made up of a decimal number in a byte unit, the authentication controller 220 receives the received master code 330. ) Is calculated in byte units, and if the calculated data values are 11, 13, 17, 19, 23, 29, 31, etc., all of them are decimals in byte units, the authentication control unit 220 generates a master code ( 330 is determined to be a valid code.

Herein, the preset condition for the master code is merely illustrative of the technical idea of the present invention, and a person skilled in the art to which the present invention belongs does not depart from the essential characteristics of the present invention. Preset conditions for the various numbers, specific number, even, odd and multiple will be applicable to various changes and modifications.

That is, the master code 330 must be included as an essential component of the master key 120.

The block code 340 is a data code including the entire master key data corresponding to the entire area or the partition master key data that divides the specific area. Here, the entire master key data is data corresponding to the entire area of each apartment or officetel, and the partition master key data is data for each apartment or officetel.

For example, suppose that a particular apartment complex consists of 5 buildings totally, 5 buildings are divided into 101 to 105 buildings, and the block code uses 1 byte of data. The data is the data (0xFF) recognized as the master key in all the buildings 101 to 105, and the partition master key data is the data (0x00 to 0Xfe) recognized as the master key only in each building. When the block code 340 includes the partition master key data, the partition master key data can be divided into data for 5 buildings, and the master key including the partition master key data for 101 buildings is 102 to Building 105 is not recognized as a master key.

In this case, when the data size of the block code is 1 byte, the block code may be divided into a total of 254 partition master key data and one total master key data.

That is, the block code 340 is data that distinguishes the partitions in the apartment complex and is an additional component that may not be used when using a single partition.

The level code 350 records data corresponding to a unique value for distinguishing a version of the electronic key for checking whether the electronic key has been updated. The level code 350 is a unique data value that can distinguish a specific master key, and may be set by the key issuer 130. The level code 350 may have a different number for each master key for authentication of the master key. Although it may be set, the level code 350 is a version concept, it is preferable that the same level code is applied to the master keys of the same function.

For example, when the master key 120 is inserted into the input unit 210 of the electronic lock 110, the electronic lock 110 reads the master code 330 of the master key 120 and then reads the master code ( If it is determined that 330 is a valid code, the level code 350 is read from the master key 120. If the electronic lock device 110 does not have a preset level code in the information storage unit 230, the electronic lock device 110 stores the received level code 350 and releases the electronic lock device 110.

The electronic lock 110 unlocks the electronic lock when the received level code 350 is matched or updated when there is a pre-stored level code in the electronic lock 110. If the received level code 350 is updated, the received level code 350 is stored and the electronic lock is released.

For example, when one of the master keys 120 is lost, the same level code 350 is set by using the key issuer 130 in all master keys except the lost master key. Thereafter, when the master key 120 having the changed level code 350 is inserted into the electronic lock 110, the electronic lock 110 updates the preset level code and the lost master key cannot be used. will be. That is, all master keys 120 whose level code 350 has been updated by the key issuer 130 have the same level code 350 that can be used without any problem.

Here, the electronic lock 110 recognizes that the level code 350 is updated when the level code 350 of the master key 120 exceeds the level code set in the electronic lock 110 at the time of initial setting. When the level code 350 of the master key 120 is less than the level code preset in the electronic locking device 110, the level code 350 may be set to recognize that the level code 350 is updated. By way of example only, those of ordinary skill in the art to which the present invention belongs may determine whether the electronic lock device 110 has updated the level code 350 without departing from the essential characteristics of the present invention. As for the identification method, various modifications and variations such as over, under, random, odd, even, and multiple may be applied.

That is, the level code 350 is an essential component as data for determining whether the electronic lock 110 is updated when the master key 120 is lost.

4 is an exemplary view showing an operation mode of the locking device according to the preferred embodiment of the present invention.

The electronic locking device 110 may operate in the standby mode 410, the installation mode 420, and the normal mode 430 as shown in FIG. 4.

The standby mode 410 is a mode of being shipped by the manufacturer of the electronic locking device 110, which means a kind of standby state.

The installation mode 420 is a mode in which the electronic lock device 110 receives the master code 330 from the master key 120 and operates when the master code 330 includes master key data.

That is, when the electronic lock 110 recognizes the electronic key as the master key instead of the general key, it operates in the installation mode 420 to perform the overall operation on the master key 120.

The normal mode 430 is a mode in which the electronic lock 110 recognizes a general electronic key or password other than the master key 120.

For example, when a general user who is not a field manager inserts a conventional electronic key into the electronic lock 110, the electronic lock 110 recognizes the electronic key and operates in the normal mode 430.

That is, when the electronic lock 110 recognizes a typical electronic key, the electronic lock 110 operates in the normal mode 430 to release the lock.

5 is a flowchart illustrating a method for operating an electronic key according to an exemplary embodiment of the present invention.

After receiving the master code 330 of the master key 120 from the input unit 210, the authentication control unit 220 of the electronic locking device 110 checks whether the master code 330 is a valid code (S510). .

That is, step S510 is a step for performing primary authentication on the master key 120, which is an essential step in the present invention.

When the master code 330 is a valid code as a result of checking in step S510, the authentication controller 220 receives the function code 310 of the master key 120 from the input unit 210 and then the data of the function code 310. Check whether or not the master key data (S520).

If the function code 310 is not the master key data as a result of checking in step S520, the authentication controller 220 receives the function code 310 of the master key 120 from the input unit 210 and then the function code 310. It is checked whether or not the data is the setting key data (S522).

As a result of checking in step S522, when the data of the function code 310 is the setting key data, the authentication controller 220 recognizes the master key 120 as the setting key and operates (S524).

On the other hand, when the result of the check in step S522, the data of the function code 310 is not the setting key data, the authentication control unit 220 receives the function code 310 of the master key 120 from the input unit 210 and then the function code It is checked whether the data of 310 is the test key data (S526).

As a result of checking in step S522, when the data of the function code 310 is test key data, the authentication controller 220 recognizes the master key 120 as a test key and operates it (S528).

On the other hand, when the result of the check in step S520, when the function code 310 is the master key data, the authentication control unit 220 checks whether or not the site code 320 is previously set using the information storage unit 230 ( S530).

That is, the authentication control unit 220 checks whether or not data (site code) classified by site as an apartment complex, an officetel complex, or the like is stored in the electronic locking device 110.

As a result of the check in step S530, when the site code 320 is not set in advance, the authentication controller 220 of the electronic locking device 110 stores the site code 320 in the information storage unit 230 (S532). .

On the other hand, as a result of the check in step S530, when the site code is set in advance, the authentication control unit 220 of the electronic locking device 110 is the site code and the site code of the master key 120 and the preset site code 230 Compared to 320, it is checked whether or not the site codes match (S534).

As a result of checking in step S534, if the site code matches, the authentication control unit 220 of the electronic locking device 110 receives the block code 340 of the master key 120 from the input unit 210 and then the block code 340 Check whether or not the entire master key data is included in step (S540).

As a result of checking in step S540, when the entire master key data is not included, the authentication control unit 220 of the electronic locking device 110 determines that the master key 120 is a partition master key that has divided a specific area, and stores the information. In step 230, it is checked whether or not the block code including the partition master key data is set.

When the block code including the partition master key data is previously set as a result of checking in step S550, the authentication controller 220 of the electronic locking device 110 determines that the block code 340 is assigned to the block code preset in the information storage unit 230. Check whether or not match (S552)

On the other hand, if the block code including the partition master key data is not previously set as a result of checking in step S550, the authentication control unit 220 of the electronic lock device 110 to block the block code 340 including the partition master key data It is received and stored in the information storage unit 230 (S554).

For example, the electronic lock device 110 is installed at the time when the internal construction is started at the construction site of the D apartment, and the electronic lock device 110 is installed by the worker or installer in the process of installing the electronic lock device 110. Enter the partition master key data once. That is, input of the partition master key data includes the partition master key data as shown in step S554 when the operator or installer inserts the master key 120 including the partition master key data into the input unit 210 of the electronic lock 110. The block code is updated and stored.

Here, the master key 120 including the premise master key data can be used directly as in step S560 without any special input procedure, and the master key 120 including the partition master key data includes data for distinguishing a specific area. Therefore, the authentication process for updating the block code 340 in step S554 or comparing the block code 340 in step S552 is performed.

That is, in the present invention, steps S530 to S554 are steps for authenticating a specific area when specific areas are distinguished, and may be omitted when using a single apartment complex or a single compartment.

When the verification result block code 340 of step S540 includes all master key data, or the block code 340 of the verification result master key 120 of step S552 corresponds to the block code preset in the information storage unit 230. If there is a match, the authentication controller 220 checks whether the level code is previously set in the information storage unit 230 (S560).

As a result of checking in step S560, when the level code is previously set in the information storage unit 230, the authentication controller 220 receives the level code 350 of the master key 110 from the input unit 210 and then the level code. It is checked whether 350 is updated (S562).

Here, when the received level code 350 exceeds the preset level code, the electronic locking device 110 recognizes that the level code 350 is updated, or the level code 350 of the master key 120 is electronic. If the lock device 110 is less than the preset level code, the level code 350 may be set to be recognized as being updated, which is merely illustrative of the technical idea of the present invention, and in the technical field to which the present invention belongs. Those skilled in the art may apply various modifications and modifications to the method of checking whether the received level code 350 has been updated by the electronic locking device 110 without departing from the essential characteristics of the present invention. Could be.

For example, if the site manager lost one master key 120 containing 101 compartment master key data at the construction site of D apartment, the site manager may delete the missing 101 compartment master key data. The level code 350 of the master key 120 including the remaining nine compartment master key data is changed using the issuer 130, or one master key is added to the master key 120 including ten compartment master key data. Level code 350 is changed.

Here, since the level code 350 is used as a concept of the version, the field manager uses the key issuer 130 to display the master key 120 including the remaining nine partition master key data with a number higher than the level code 350 before being lost. Is changed to the level code 350.

According to a preferred embodiment of the present invention, it is preferable that the level code 350 is gradually increased, but in actual implementation of the invention, the level code 350 may be gradually reduced, which is common knowledge in the art to which the present invention belongs. Persons having the present invention may have various modifications and variations without departing from the essential characteristics of the present invention.

When the level code is not previously set in the confirmation result information storage unit 230 of step S560 or when the check result level code 350 of the step S562 is an updated key, the authentication control unit 220 receives an input from the input unit 210. After receiving the level code 350 of the master key 110 is stored in the information storage unit 230, and generates an authentication success signal and transmits to the device control unit 240 (S564).

For example, when the master key 120 including the 101 partition master key data having the changed level code 350 is inputted to all the electronic locks 110 installed in the 101 blocks, the electronic lock 110 performs the steps S560 and the step. The level code 350 is to be stored as S562.

That is, if it is assumed that the level code of the lost master key is about 2.0, the site manager changes the remaining nine levels of the master key not lost to 3.0 using the key issuer 130, and the worker or installer changes the level. The master key to which the code is applied is inserted into all the electronic locks 110 installed in the 101 building, and as shown in step S560, the electronic lock device 110 changes the level code 3.0 so that the preset level code 2.0 is exceeded. In operation S562, the electronic locking device 110 determines that the changed level code 3.0 is higher than the preset level code 2.0 and stores the changed level code in the information storage 230.

For example, assuming that each building is composed of 80 households, the master key needs to be re-registered 9 master keys except the untrusted master key in the conventional method, and thus the master key after 3600 (9 × 5 × 80) re-registration processes. However, if the above-described method is used, it is possible to use the update of the preset level code of 400 (1 × 5 × 80).

If someone acquires the master key containing the lost compartment master key data and inserts it into the lock installed in the 101 building, the level code has been updated to 3.0 by the changed level code 3.0, and thus the lost master of step S560 Since the level code (2.0) of the key does not exceed the preset level code (3.0), and the preset level code (3.0) does not match the level code (2.0) of the lost master key as in step S570, the locking device Is not freed.

On the other hand, when the verification result of step S562, the level code 350 of the master key 120 does not exceed the level code set in the information storage unit 230, the authentication control unit 220 of the electronic lock device 110 It is checked whether the level code 350 of the master key 120 is the same as the preset level code of the information storage unit 230 (S570).

As a result of checking in step S570, when the level code 350 of the master key 120 is the same as the preset level code of the information storage unit 230, the authentication control unit 220 of the electronic lock device 110 is the master key 120 Determines that the level code 350 is the same version as the preset level code of the information storage unit 230, generates an authentication success signal, and transmits the authentication success signal to the device controller 240, and the device controller 240 drives the driver 260. Control the lock to release (S580).

That is, in step S560 to step S570, when the master key 120 is lost in the present invention, when the level code 350 is updated, the level code is updated and stored to perform authentication, or the level code 350 is set to a preset level. If it matches the code by allowing authentication, it is an essential step to be unable to authenticate with the lost master key (120).

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, in using the electronic key as a master key, the electronic lock device checks whether the data code received from the electronic key is updated, and if the data code is updated, a separate registration procedure is performed. By unlocking the lock by storing the updated data code without going through it, the field manager does not have to perform a procedure for separately registering the master key with the electronic lock, thereby increasing the convenience of using the master key.

In addition, when the master key is lost, by registering only one master key among a plurality of master keys whose data codes are updated, convenience of an operator or an individual user at a construction site is increased.

In addition, when the master key is lost, when the operator or user updates the data code of the master key that is not lost by using the key issuer, the electronic lock device receives and stores the updated data of the master key, and thus, the leaked master key. It can be quickly protected from the effect of increasing the security of the electronic lock.

In addition, since the limitation of the number of registering the master key in the memory of the electronic lock device can be removed, there is an effect that the master key can be integratedly managed.
