Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable terminal having a key function used for locking and unlocking a lock, and more particularly to a portable terminal having a master key function capable of locking and unlocking different locks.
[0002]
[Prior art]
A general machine security system is a building or occupant who is unattended at night or on a holiday by installing a sensor and a reporting device that detects abnormal situations such as intruders and fires in the contracted building or residence that is subject to security. Go out and guard the house that was absent.
[0003]
When the sensor detects an abnormal situation, the reporting device notifies the monitoring center of the security company that the abnormal situation has been detected via a telephone line or the like.
[0004]
Upon receiving the notification, the monitoring center of the security company dispatches a security guard to the building or residence to check the situation, and also makes a request for dispatch to related organizations such as the police and fire department as necessary.
[0005]
The security guard dispatched to the site enters the building or the residence using the key borrowed from the contractor in advance, and investigates the cause of the abnormality detected by the sensor.
In addition, depending on the status of the abnormality that has been confirmed, necessary measures are taken to collect the situation or to prevent the spread of damage.
[0006]
[Problems to be solved by the invention]
However, regarding the key for entering the building or residence of the contract partner, there are the following problems and problems to be improved.
[0007]
(1) The borrowed key is stored in a dedicated key box, and the key box is stored in the guard's waiting area or placed on the guard's guard vehicle in charge of the area, but the number of keys increases. As it becomes, it becomes difficult to secure a storage location.
[0008]
(2) Each guard is assigned a district in charge, and when an abnormal situation is detected, a guard in charge of the district is dispatched. However, if the security officer in charge of the district cannot go to the site because it is handling another case, a security officer in charge of the adjacent district must be dispatched instead. At this time, the security officer in charge of the adjacent district does not have the key of the contractor in the district, so it must join the security officer in charge of the district at any location and deliver the key. It was.
[0009]
In addition, when the contractor's key is kept in the guard's waiting area, either when the security officer in charge of the district is dispatched or when the security officer in charge of the adjacent district is dispatched instead I had to stop at the waiting area in the district and go to the site.
[0010]
Therefore, in order to deliver the key, time to go to the site was lost.
[0011]
This situation will be further described with reference to FIG.
[0012]
As shown in the figure, the districts in charge of the guards a to d are assigned as the A district to the D district, and each guard is waiting at a waiting place in each district. The keys to enter the contracted buildings in each district are stored by the guards in each district.
When an abnormal situation is detected in the contractor A1 in the A district, the guard a is dispatched to the contractor A1 in response to an instruction from the monitoring center, and performs measures such as checking the situation.
[0013]
At this time, if an abnormal situation is detected in the contractor A2 in the A district, the guard a is originally dispatched to the contractor A2, but cannot respond because it is dispatched to the contractor A1.
[0014]
Therefore, security officer c in district C, which is the neighboring district, is dispatched to contractor A2, but since guard c does not have the key of contractor in district A, contractor A2 joins guard a. Or to the contracting party A2 after approaching the waiting place A, it is greatly bypassed as compared with the case of going directly to the contracting party A2.
[0015]
Therefore, it took extra time to arrive at the site.
[0016]
(3) In addition to the case where an abnormal situation is detected at the contractor and a security guard enters the building to check the situation, maintenance personnel are required to ensure that the security equipment such as sensors installed at the contractor functions normally. The key borrowed from the contractor is also used when entering the contractor's building for inspection or replacement work.
[0017]
Even in such a case, it was necessary to pass the key between the security staff in charge of the district and the maintenance staff, resulting in wasted time and trouble.
[0018]
(4) Duplicate the key in advance so that it is not necessary to deliver the key in (2) and (3) above, and pass it to the security officer in charge of the district and the security officer in charge of the adjacent district. Although the number of keys stored by each security guard increases significantly, the risk of theft or loss increases as the number of keys increases. It was not possible to carry out because of resistance to
[0019]
(5) In buildings with a large number of rooms, such as hotels, a master key method is employed as a means for eliminating the need to carry many keys. The master key method is a method in which a plurality of locks are locked and unlocked using a master key. By applying this method, the number of keys that the guards must store can be reduced.
[0020]
However, the conventional master key method may be misused by others if the master key is lost or stolen. If such a situation occurs, it is necessary to replace all the locks corresponding to the master key, which requires a great deal of cost and labor.
[0021]
Therefore, the conventional master key method could not be easily introduced as a key for security guards to enter the buildings of multiple contractors.
[0022]
(6) In order to reduce the number of keys kept by security guards, it may be possible to replace the lock used at the entrance / exit of the contracted building with an electric lock so that it can be locked / unlocked with a password. It is not easy to install an electric lock due to the fact that the electric lock itself is expensive, and when the electric lock is installed later, it is necessary to carry out wiring work to secure the power supply, which increases the construction cost. could not.
[0023]
(7) There are various types of locks used in the contracted building, such as cylinder type, those using a numeric keypad (password), and those using ID cards such as magnetic cards. These locks are mixed in the district in charge.
[0024]
Therefore, in the case where the number of keys stored by the security guard is to be reduced, ideally a means is required that can cope with the case where different types of locks exist.
[0025]
The present invention has been made to solve the above-mentioned problems, and it is not necessary for the security guard to store a large number of contracted keys, and it is not necessary for the security guard to pass the keys. An object of the present invention is to provide a portable terminal having a key function.
Another object of the present invention is to prevent unauthorized use of a portable terminal having a key function by preventing unauthorized use even if the portable terminal is stolen or lost.

Carry out maintenance work such as repair and inspection of equipment. When the maintenance work is completed, the maintenance person b1 locks the lock k with the portable terminal 1 and leaves.
[0050]
When receiving only the key data required in the field
Next, based on FIG. 4, as another procedure, when the security guard a1 or the maintenance staff b1 is dispatched to the contracted building A1, and requests only the key data necessary for the monitoring center 100 at the site and transmits it. explain.
(G) Dispatch of security guards and maintenance personnel
When the sensor s installed in the contracted building A1 detects that an abnormal situation has been detected, a dispatch instruction or inspection of security equipment is requested, and the security guard a1 or the maintenance staff b1 heads for the site. At this time, the key data is not transmitted.
(H) Get lock ID
When there is a lock that needs to be locked / unlocked at the site, the security guard or the maintenance staff sends the lock ID from the lock control device (not shown) to the portable terminal 1 or the identification number assigned to the lock. A security guard or maintenance staff confirms and inputs it to the portable terminal 1, and acquires the ID of the lock to be unlocked.
(I) Request lock data, send lock data
The lock ID obtained in (h) is transmitted to the monitoring center 100 to request key data for locking and unlocking. The monitoring center 100 transmits lock data corresponding to the lock ID based on the request.

The security guard a1 or the maintenance staff b1 uses the key data received from the monitoring center 100, unlocks the lock k provided in the contracted building A1 by the mobile terminal 1, enters the inside, and takes necessary actions. When the operation is completed, the portable terminal 1 locks the lock k and exits.
[0051]
When requesting the key data, if the monitor in the monitoring center 100 directly responds, the procedure for transmitting the key data may be a burden on the monitor.
Therefore, an automatic response device (not shown) is installed in the monitoring center 100, and when a security guard or a maintenance person requests key data, identification information such as a lock ID is sent, so that the automatic response device of the monitoring center is automatically In other words, key data to be transmitted to the mobile terminal may be selected and transmitted.
[0052]
Necessity of authentication
In the business flow, key data is transmitted from the monitoring center to the guards or maintenance personnel, and the locks provided at the entrances and exits of the contracted parties by the mobile terminals are performed.
[0053]
Here, since the following illegal acts are assumed, a confirmation act for preventing the illegal acts is necessary.
[0054]
When transmitting key data in (b), (e), and (i), to prevent unauthorized acquisition and unauthorized use of key data, to which portable terminal the key data is transmitted, or when the key data is transmitted You need to know who was using your mobile device.
[0055]
In particular, in (e) and (i), it is conceivable that a third party may falsely request key data, so that it is a legitimate mobile terminal or given a right to use the mobile terminal. It is important to make sure that you are the right person.
[0056]
When locking / unlocking the locks in (c), (f), (j) above, in order to prevent unauthorized locking / unlocking, the mobile phone must be a legitimate mobile terminal or a person who has been authorized to use the mobile terminal. It is necessary to check if it exists.
[0057]
Unauthorized locking / unlocking can be done either by manufacturing an unauthorized device with the same function as a mobile device and locking / unlocking it, or by unauthorized use of a legitimate mobile device by a third party. Confirmation to prevent these actions is important.
[0058]
Therefore, when using the mobile terminal according to the present invention, authentication is incorporated as a confirmation act to prevent fraud.
[0059]
This authentication is not an indispensable procedure. Depending on the procedure and communication method used when giving instructions to the security guard from the monitoring center, it is possible to confirm the other party without performing authentication, or depending on the type of lock. This is not necessary if the effect of preventing unauthorized use cannot be obtained even if authentication is adopted.
[0060]
Mobile device configuration
Next, an embodiment of the portable terminal according to the present invention will be described. FIG. 5 shows a block diagram of a portable terminal according to the present invention, where (a) shows a portable terminal 1 of the first embodiment and (b) shows a portable terminal 2 by a second embodiment portable. 5A shows an example in which the functions of the mobile terminal and the mobile phone are integrated, and the mobile terminal 2 in FIG. 5B connects the mobile terminal to the mobile phone. An example of use is shown. FIG. 6 shows an external configuration diagram of the mobile terminal 1 in FIG. 5A and the mobile terminal 2 in FIG.
[0061]
5A includes a display unit 11, an operation unit 12, an authentication unit 13, a control unit 14, a storage unit 15, a transmission / reception unit 16, a locking / unlocking signal output unit 17, and a tamper resistant means 18.
[0062]
The mobile terminal 2 in FIG. 5B is basically the same except for the point that an input / output unit 19 is provided instead of the transmission unit 16 of the mobile terminal 1. Therefore, in the case of FIG. 5B, the input / output unit 19 and the mobile phone (wireless device or the like) 20 correspond to the transmission / reception unit 16 of FIG.
[0063]
The display unit 11 displays various types of information such as input confirmation when operating the operation unit 12 and confirmation of operation results. If the lock of the contracted building is to be locked and unlocked with a password, the password may be displayed.
[0064]
The operation unit 12 performs operations for security guards or maintenance personnel to lock and unlock, and (if necessary) input of a personal identification number for authentication.
[0065]
When the mobile terminal 1 receives the key data or is used to lock / unlock the lock provided at the contracted party, the authentication unit 13 gives the user a proper authority to use the mobile terminal 1. Authentication is performed to confirm whether or not the person is a registered person. At the time of authentication, existing techniques are used as appropriate, such as input of a personal identification number, fingerprint collation, and reading of an ID card owned by the user. When fingerprint verification or ID card reading is performed, it is necessary to connect a fingerprint input device or a card reader to the portable terminal 1 or to provide the function on the portable terminal.
[0066]
The control unit 14 performs various controls of the mobile terminal 1.
[0067]
The storage unit 15 stores key data received from the monitoring center.
[0068]
The transmission / reception unit 16 integrates the functions of a radio and a mobile phone, and is used as a communication means with the monitoring center and also receives key data. During communication with the monitoring center, authentication data is also transmitted and received here.
[0069]
The locking / unlocking signal output unit 17 transmits a locking / unlocking signal to an input means such as a card reader provided for locking / unlocking the lock installed at the contractor, and locks / unlocks the lock.
The locking / unlocking signal is not limited to a signal used for directly locking / unlocking, but may be identification information used for locking / unlocking.
[0070]
For example, when the input means is a card reader that reads a non-contact card, identification information for locking / unlocking is transmitted from the non-contact card to the card reader, and locking / unlocking is performed when the identification information is confirmed by the lock control device. It is. The locking / unlocking signal output unit locks and unlocks the lock by transmitting information similar to the identification information stored in the non-contact card and transmitted to the card reader to the card reader.
[0071]
In the case where the input means is a numeric keypad for inputting a personal identification number, the personal identification number may be displayed on the display unit 11 of the portable terminal, and a security guard or the like may input the personal identification number.
[0072]
The tamper resistant means 18 deletes the key data when it is detected that the mobile terminal 1 has been disassembled in order to prevent unauthorized removal of the key data due to the disassembly of the mobile terminal 1 or the like. In addition, if there is information other than the key data that is not desired to be obtained illegally, it may be deleted at the same time.
[0073]
The input / output unit 19 is connected to another wireless device 20 such as a mobile phone 20a and a wireless device 20b to exchange signals.
[0074]
When a higher level of security is required, when authentication is performed to confirm that the mobile terminal is genuine, the authentication and unlocking signal output are performed as a series, and the authentic mobile terminal is authenticated. It will be allowed to lock and unlock after being recognized.
[0075]
The transmission / reception unit 16 (input / output unit) and the locking / unlocking signal output unit 17 may be shared.
In addition, the mobile terminal 1 includes a battery (not shown) that supplies power. When a retrofitted electric lock is used, a power source for driving the electric lock device may be supplied.
[0076]
The portable terminal 1 according to the present invention receives key data from the monitoring center through communication with the monitoring center. At this time, any of the following communication means may be used.
[0077]
Connecting to a radio
When the monitoring center and the security staff (maintenance staff) give instructions from the monitoring center or report from the security staff, when the radio is used, the radio 20b and the portable terminal 2 are connected with a cable, etc. It is only necessary to connect using and receive key data.
[0078]
Connection with mobile phone and PHS
When a mobile phone or PHS 20a is used between the monitoring center and a security guard (maintenance staff) when an instruction from the monitoring center or a report from the security guard is used, the mobile phone or PHS 20a and the mobile terminal are connected. A connection cable or the like may be used for connection to receive key data.
[0079]
Wireless devices, mobile phones, and PHS functions are provided in mobile terminals
Like the portable terminal 1 in FIG. 5 (a), the portable terminal is provided with a communication function using a radio, a cellular phone, a PHS, etc., and is used for instructions from the monitoring center and reports from security guards. Reception can be performed.
[0080]
If a mobile phone or PHS function is provided, the mobile terminal can be specified by telephone number when calling the mobile terminal from the monitoring center, and the caller ID notification is used when calling the monitoring center from the mobile terminal. The mobile terminal can be specified.
[0081]
Therefore, in this case, when transmitting the key data from the monitoring center, authentication for confirming whether or not the mobile terminal is an authorized mobile terminal can be omitted.
[0082]
Enter the encryption code into the mobile device
When giving instructions to the security guard from the monitoring center using a mobile phone or radio, the monitoring center transmits an encryption code (for example, a sequence of about 10 digits) as key data, and the security guard carries the encryption code with the mobile phone. The data is input to the terminal, decrypted by the mobile terminal, and used as key data.
[0083]
When this encryption code is generated, different encryption codes are generated depending on the date using parameters such as date, and the encryption code obtained by encrypting the key data for locking and unlocking a certain lock is the same. It is preferable not to become.
[0084]
Also, in the authentication when sending the key code, the same encryption-combined algorithm is used, the encrypted code obtained by encrypting the identification number of the security guard and the portable terminal is transmitted to the monitoring center, and the monitoring center combines it. Confirmation may be taken.
[0085]
In this case, there is an advantage that a wireless device or the like used for communication between the monitoring center and the security guard can be used as it is.
[0086]
About authentication of person using mobile terminal
As a method for confirming whether or not the person who uses the mobile terminal is a person who has been given the right authority, the following method can be considered.
[0087]
(A) Authentication on mobile terminals
When receiving key data from the monitoring center, when locking / unlocking with a mobile terminal, information to be compared previously stored in the mobile terminal and information stored in an ID card owned by the person using the mobile terminal Are compared and authenticated.
[0088]
(B) Authentication at the monitoring center
When receiving the key data from the monitoring center, the information stored in the user's ID card and the biometric information such as the user's fingerprint read by the portable terminal are transmitted to the monitoring center and stored in advance in the monitoring center. Authentication is performed by comparing with information to be compared.
[0089]
When locking / unlocking with a mobile terminal, authentication may be performed at the monitoring center as in the case of receiving key data. However, since communication is performed with the monitoring center each time locking / unlocking is performed, communication costs increase. In addition, there is a possibility that the mobile phone or PHS cannot be used in the building and authentication cannot be performed.
[0090]
Therefore, when locking and unlocking is performed by the mobile terminal, it is only necessary to confirm whether or not the user is the same person as the user who performed authentication when receiving the key data. Therefore, the portable terminal stores user information used for authentication when receiving the key data, and compares and compares the stored information with the user information when locking and unlocking.
[0091]
About mobile device authentication
There are the following methods as authentication methods for confirming that the mobile terminal is authorized when receiving the key data from the monitoring center.
[0092]
An identification code is assigned to the mobile terminal in advance. In the monitoring center, each identification code assigned to the mobile terminal is registered.
[0093]
When the mobile terminal communicates with the monitoring center to receive the key data, the mobile terminal transmits its own identification code to the monitoring center, and the monitoring center compares the sent identification code with a previously registered identification code, Make sure it ’s a legitimate mobile device.
[0094]
At the same time, it may be authenticated that the user of the portable terminal is a person who has been given the right authority.
[0095]
In addition, the monitoring center prepares a database in which correspondence relations between responsible areas, guards (maintenance personnel), and mobile terminals are registered in advance, and the area where the target contractor is located in the authentication when handing over key data Further, by confirming that the correspondence between the user of the mobile terminal and the mobile terminal is correct, authentication with higher reliability may be performed.
[0096]
When it is confirmed that the monitoring center is an authorized mobile terminal, the monitoring center transmits key data to the mobile terminal. The key data to be transmitted at this time is only the key data that is required at the contracting destination. Note that if the contractor requires a plurality of key data, a plurality of key data is transmitted.
[0097]
Depending on the communication method between the mobile terminal and the monitoring center, confirmation that the mobile terminal is genuine can be simplified.
[0098]
When the mobile terminal has a mobile phone or PHS function like the mobile terminal 1, when calling the mobile terminal from the monitoring center, the target mobile terminal can be specified by the telephone number, and the monitoring center is called from the mobile terminal. At this time, the monitoring center can identify the mobile terminal using the caller ID notification.
[0099]
Therefore, by using these, it is possible to confirm that the mobile terminal is genuine, and it is not necessary to perform confirmation using an identification code or the like.
Authentication between mobile terminal and contracted lock (in case of retrofitted electric lock)
When using a so-called `` retrofitted electric lock '' that is additionally attached to a mechanical lock such as an existing cylinder lock and which can be electrically controlled, an external power supply is used to send an unlocking signal. If it is possible to lock and unlock only by inputting, any battery can be connected and any person can lock and unlock by inputting a locking and unlocking signal from an arbitrary control device.
[0100]
In order to prevent this, when using a retrofitted electric lock, it is necessary to confirm that it is a legitimate portable terminal by performing authentication between the electric lock and the portable terminal.
[0101]
FIG. 7 shows an example in which authentication is performed using a public key.
[0102]
In the electric lock control device 30, a public key (1), a secret key (1), and key data (lock ID 123) issued from an arbitrary certificate authority A are registered in advance. In the portable terminal 1, a public key (2) and a secret key (2) issued from an arbitrary certificate authority A are registered in advance. Authentication is performed according to the following procedure.
(1) When entering a contracted building due to an abnormal situation detection or maintenance work, etc., authentication is performed between the monitoring center 100 and the portable terminal 1, and then the monitoring center 100 encrypts with the public key (2). The converted key data (lock ID 123) is transmitted to the portable terminal 1 (S1).
(2) The public keys (1) and (2) registered in advance are exchanged between the electric lock control device 30 and the portable terminal 1, and it is mutually confirmed that the certificate is approved by an arbitrary certificate authority A. (S2).
(3) The electronic lock control device 30 transmits a document in which the key data (lock ID 123) encrypted with the public key (2) received in (S2) is sent to the portable terminal 1 and requests a signature. (S3).
(4) The mobile terminal 1 decrypts the document received in (S3) with its own private key (2), controls the key data transmitted from the monitoring center 100 in (S1), and controls the electric lock in (S3). The key data transmitted from the device 30 is compared (S4).
(5) If the key data are equal, the portable terminal 1 digitally signs the document decrypted in (S4) (S5).
(6) The document digitally signed in (S5) is encrypted with the public key (1) received in (S2) and transmitted from the portable terminal 1 to the electric lock control device 30 (S6).
(7) After confirming the signature, the electric lock control device 30 locks and unlocks (S7).
[0103]
According to the example shown in FIG. 7, there is almost no fear of being misused by others due to strict authentication, and high reliability that can be used even in important facilities can be obtained.
[0104]
However, when it is used in a general building, it becomes too strict than necessary, and there is a risk that it becomes a burden on management.
[0105]
The portable terminal 1 according to the present invention cannot be used unless the key data is transmitted from the monitoring center 100, the portable terminal 1 is genuine when the key data is transmitted from the monitoring center 100, and the portable terminal 1 is used. That the user is authorized and that the portable terminal 1 takes measures to prevent unauthorized acquisition of the key data, and therefore sufficient reliability can be achieved even if a part of the authentication is simplified. Can be obtained.
FIG. 8 shows an example in which a part of authentication is simplified in the example of FIG.
[0106]
In the electric lock control device 30, a public key 1, a secret key 1, and key data (lock ID 123) issued from an arbitrary certificate authority A are registered in advance.
(1) When entering a contracted building due to an abnormal situation detection or maintenance work, etc., the authentication is performed between the monitoring center and the portable terminal, and then encrypted with the public key (1) from the monitoring center. Lock information (lock ID 123) is transmitted to the portable terminal 1 (S11).
(2) The portable terminal 1 transmits the encrypted key data (lock ID 123) received from the monitoring center 100 in (S10) and the lock / unlock signal to the electric lock control device 30 (S12).
(3) The electric lock control device 30 decrypts the encrypted key data (lock ID 123) received in (S12) with the secret key (1) and compares the key data (lock ID 123) (S13). ).
(4) After confirming the coincidence of the key data, it is locked / unlocked by the locking / unlocking signal received in (S12) (S14).
[0107]
Handling of key data stored in mobile terminals
The mobile terminal 1 stores the key data received from the monitoring center 100. However, even if the mobile terminal 1 is stolen or lost, the following countermeasures are taken in order to minimize damage caused by leakage of the key data. The portable terminal 1 stores a minimum number of key data only while it is needed.
(1) When new key data is received from the monitoring center 100, the key data received in the past is deleted.
(2) Erase by operating the erasing means provided on the mobile terminal 1 (after the security guard has confirmed the abnormality and the situation has been collected and the security guard has left the contracted building (the entrance door is locked) Just do it.)
(3) After receiving the key data from the monitoring center 100, it is valid for a certain period of time and is deleted. Information specifying the validity period is included in the key data.
(4) A tamper switch is provided in the portable terminal 1 and the key data is deleted when the portable terminal 1 is disassembled.
(5) When unlocking is performed once, the key data is deleted (or the unlocking operation is prohibited).
(6) Valid until unlocking operation is performed after unlocking.
(7) When the end of work is notified to the monitoring center 100, the operation is deleted by an operation from the monitoring center 100 (sending an erasure command from the monitoring center to the portable terminal).
[0108]
Regarding the handling of key data, both locking and unlocking operations may be prohibited by deleting the key data, but only the unlocking operation may be prohibited.
This is because even if there is a possibility of being misused by being unlocked illegally, the possibility of being misused by being illegally locked is very low.
[0109]
Breakdown of key data
The possible breakdown of key data is shown below. Select and use the following information as needed.
(1) Identification information
Information used for verification in the control device on the lock side when the lock is unlocked.
[0110]
This information is the same as the information sent to a card reader or the like when locking / unlocking using a device other than a mobile terminal, such as identification information, a personal identification number, and an individual ID code transmitted from a contactless card.
(2) Lock information (ID) of the lock to be unlocked
This is used to confirm whether or not the target lock is correct when locking and unlocking.
(3) Types of locks (used when locking / unlocking different types of locks)
It is used to change the data for authentication and the output method of the lock / unlock signal according to the target lock. Based on this information, wireless transmission / reception, display of a personal identification number or the like on the display unit, and input / output of a signal through an arbitrary input / output terminal are switched.
(4) Key data erasure conditions (used to change the erasure conditions according to the situation, such as the number of valid times and valid period)
If the object to be locked / unlocked is the entrance door of the building, it is sufficient that it can be locked / unlocked only once. However, if a common key is required for the entrance doors of each floor, it must be locked / unlocked multiple times. In such a case, an effective period (for example, 2 hours) may be determined based on the required work time instead of the number of times.
(5) Lock name, etc. (Used to lock / unlock multiple locks, when the security guard selects the lock / unlock signal according to the lock to be unlocked / locked; “building entrance door”, “○ floor entrance door”, etc.) Name)
When locking and unlocking a plurality of locks with a mobile terminal, the guard must select and specify which lock is to be unlocked. It is the name of the lock to be used at that time.
Contractors who use cylinder locks
In an tenant building or the like, when an electric lock is provided at an entrance door and the door is locked or unlocked by a card or a password, the portable terminal according to the present invention can be easily introduced.
[0111]
However, when a cylinder lock is used for the entrance / exit door, or in a tenant building, etc., the entrance / exit door of the building can be locked / unlocked with a PIN or a card, but a cylinder lock is used for the door of each tenant These doors cannot be directly locked or unlocked by the portable terminal according to the present invention.
[0112]
Such a case is dealt with by adding a configuration as shown below.
(1) Install a key storage box.
[0113]
A key storage box is installed, and a key for locking and unlocking the cylinder lock is stored in the key storage box.
The key storage box may be installed outside the building if the entrance door of the building is a cylinder lock, or near the entrance inside the building if only the door of each room inside the building is a cylinder lock.
[0114]
The key storage box can be opened and closed by a card or a personal identification number, and a key stored in the key storage unit can be taken out. A security guard or the like may use a portable terminal to open and close the key storage box and take out the key instead of using a card or a password.
[0115]
In this case, there is an advantage that the customer can use the key used for locking and unlocking the conventional cylinder lock as it is.
[0116]
It should be noted that the key storage box can be used not only by the security guard but also by the customer, and the customer stores the key in his / her room in the key storage box and takes out the key using the card or PIN. You may make it utilize.
(2) Replace the door lock with an electric lock.
[0117]
When replacing the door lock with an electric lock, installation of the electric lock is somewhat expensive, but the risk of unauthorized unlocking due to picking that occurred in the case of a cylinder lock is eliminated, so the security performance is greatly improved. .
[0118]
In tenant buildings, etc., change only the building entrance to an electric lock, and install a key storage box inside the building to store the key for unlocking and unlocking each tenant's entrance / exit in the key storage box. Also good.
(3) Add an electric lock to the door lock.
[0119]
A problem in installing the electric lock is that the installation cost is high.
[0120]
Therefore, it could not be easily installed except for contractors and important facilities that have a financial allowance.
[0121]
When an electric lock is additionally installed, it is necessary to carry out a large-scale wiring work or to newly install a power supply device for driving the electric lock, which increases the construction cost.
[0122]
Therefore, an electric lock is additionally installed in the cylinder lock portion, and when the guard or maintenance staff locks / unlocks, the lock is changed to lock / unlock with the electric lock. When the contractor locks / unlocks, the conventional key is used as it is.
[0123]
The additionally installed electric lock is not always supplied with power, but becomes effective when a security guard or the like receives power supply from a battery carried by the guard, and is locked and unlocked by a signal from a portable terminal. Eliminate extensive wiring work and reduce installation costs.
About the structure of a retrofit electric lock
The above-mentioned retrofit electric lock is an electric lock by adding a control device for electrically controlling the cylinder lock in order to enable locking and unlocking by a portable terminal even in a contractor where the cylinder lock is already used. It has the same function. Hereinafter, the retrofitted electric lock will be described with reference to FIGS. 9 to 13.
[0124]
First, referring to FIG. 9, a retrofit electric lock 50 according to the present invention is attached to a cylinder lock 90 and is roughly constituted by a power supply terminal 60, a control unit 70, and a drive unit 80.
[0125]
The power supply terminal 60 is a terminal for supplying power for causing the control unit 70 and the drive unit 80 to function, and a guard or maintenance staff connects the battery 200 and supplies power.
[0126]
The control unit 70 operates with the electric power supplied from the power supply unit 60 and controls the drive unit 80 to lock and unlock the lock. At this time, authentication or the like is performed with the portable terminal 1 so that unauthorized locking / unlocking is not performed.
[0127]
As will be described later, the drive unit 80 includes a motor and a link mechanism, drives the motor under the control of the control unit 70, and locks and unlocks the lock by rotating the cylinder of the cylinder lock 90 via the link mechanism.
[0128]
The contractor uses a conventional key to lock and unlock.
[0129]
Here, details of the retrofitted electric lock will be described with reference to FIGS. FIG. 10 is a schematic view showing a state in which the cylinder lock 90 and the retrofitted electric lock 50 are attached to the door 200. The cylinder lock 90 includes an external door knob 92 a and an internal door knob 92 b attached to both ends of the rotating shaft 91 that penetrates the door 200, and a dead bolt 93 that enters and exits from the end surface of the door 200 as the rotating shaft 91 rotates. The external door knob 92a has a cylinder portion 93 into which a key is inserted. The rotary shaft 91 rotates the rotary shaft 91 by rotating the key 95 inserted into the cylinder portion 94 or the internal door knob 92b, and allows the dead bolt 93 to be moved in and out to be in a locked state and an unlocked state. is there.
[0130]
The retrofit electric lock 50 is mounted inside the door 200, the drive unit 80 is driven via the control unit 70 by the power supplied from the power supply terminal 60, and the rotary shaft 91 of the cylinder lock 90 is rotated by the drive of the drive unit 80. To lock and unlock.
[0131]
11 and 12 illustrate a drive mechanism of the retrofitted electric lock drive unit 80. FIG. The drive unit 80 includes a link mechanism 84 that is driven via a motor 81 and gears 82 and 83.
[0132]
The rotation of the motor 81 is transmitted to the gear 83 via the gear 82. The gear 83 is provided with a slit 83a, and a hook 84a provided at one end of the link mechanism is engaged with the slit 83a. Even if the gear 83 rotates, no force is transmitted to the link mechanism 84 until it contacts the hook 84a.
[0133]
When the gear 83 rotates until it abuts against the hook 84a and further rotates, the force is transmitted to the link mechanism 84, the link mechanism 84 moves as shown in the figure, and the rotary shaft 91 connected to the other end of the link mechanism 84 rotates. Is done.
[0134]
FIG. 12 shows a state (dotted line) in which the rotating shaft 91 is rotated by the rotation of the motor 81. In this way, the rotary shaft 91 can be rotated using the force of the motor 81 and unlocked.
[0135]
By the way, the slit 83a is not necessary if the force of the motor is merely transmitted to the rotating shaft.
[0136]
However, when the motor 81 and the rotary shaft 91 are connected, the rotary shaft and the motor are simultaneously rotated when attempting to lock and unlock using a key without using a retrofitted electric lock. A load is applied. The slit 83a is provided so as not to apply a load when locking / unlocking using a key or the like, and functions as a play that blocks transmission of force between the link mechanism and the gear mechanism. FIG. 13 is a diagram for explaining the function of the slit 83a. In order to avoid the above-described load, when locking / unlocking with the retrofitted electric lock 50, after locking / unlocking (FIG. 13 (1)), the gear 2 is reversed by the amount provided with the slit 83a. (Fig. 13 (2)).
[0137]
In this state, even when locking / unlocking with a key or the like, the rotation of the rotary shaft is not transmitted to the gear 2, so that no load is applied by the motor ((3) in FIG. 13).
[0138]
About means to give mobile terminals versatility
Currently, various types of locks are used for entrance doors of buildings and the like, and there are various methods for locking and unlocking these locks. The main methods currently used include a method using a key, a method using a personal identification number, and a method using an ID (for locking and unlocking) card such as a magnetic card or a contactless card. In the future, it is expected that IC cards having higher security than conventional cards will be used.
[0139]
From the viewpoint of reducing the number of keys kept by the security guard and eliminating the key delivery, ideally, all the locks may be locked and unlocked by the portable terminal. In that case, the security guard only needs to have a portable terminal.
[0140]
In order to realize this, all the locks may be changed to those that can be locked and unlocked by the portable terminal, or the locking and unlocking signal output from the portable terminal may be output in a format suitable for various locks.
[0141]
Here, the case where the locking / unlocking signal output from the portable terminal is output in a format adapted to various locks will be described.
[0142]
In order to output the locking / unlocking signal in a format adapted to various locks, a function for outputting a signal in a different format is provided in the portable terminal, or an adapter is connected to the portable terminal.
[0143]
For example, for a lock that is locked and unlocked by a contactless card, a signal for unlocking and unlocking is input / output by wireless transmission / reception means. The number may be displayed.
[0144]
For locks that are locked and unlocked with a magnetic card, connect the card-shaped adapter to the mobile terminal and send the identification information directly to the magnetic card reader, or connect the magnetic card writer to the mobile terminal and write the identification information to the magnetic card. Thus, a magnetic card may be made, and the magnetic card may be used for locking and unlocking.
[0145]
However, to prevent the magnetic card made in this way from being abused, the mobile terminal stores information on the magnetic card created and reads the magnetic card into the magnetic card writer within a predetermined time after making the magnetic card. The identification information is deleted (if the magnetic card is not read within a predetermined time, the monitoring center may be informed that there is an abnormality, or the mobile terminal may be disabled). Only when a magnetic card is read, a new magnetic card may be created by overwriting identification information or the like on the magnetic card.
[0146]
In addition, in order to support a new type of lock, the lock data transmitted from the monitoring center includes the data format when outputting the locking / unlocking signal, and information specifying the output method (wireless etc.), Based on the information, a lock / unlock signal may be output in a format corresponding to each lock.
[0147]
About the security / security release settings of the machine security system
The portable terminal according to the present invention is used when entering a contracted building where a guard or maintenance staff is locked.
[0148]
In this case, in the facility where the machine security system is used, the security system is set to the security state, so the security guard or the maintenance staff must release the security, or the security guard etc. has entered. It must be set to the cyclic mode, which is a mode indicating.
[0149]
The machine security system is set using an ID card such as a magnetic card or a non-contact card or a personal identification number, and means similar to those used when locking and unlocking the contracted building are used.
[0150]
Therefore, using the portable terminal according to the present invention, a security / security release signal may be transmitted instead of the locking / unlocking signal to set the security / security release.
[0151]
About mobile device users
The portable terminal according to the present invention has been described by taking an example of a case where a security guard or maintenance staff of a security company uses it. If the equipment is abnormal and equipment abnormality occurs, use the mobile terminal to enter the building or use it when the contractor who carries out the cleaning of the building carries it to the building for cleaning at night or early morning. Or you may.
[0152]
【The invention's effect】
According to the present invention, various effects can be obtained as described below.
[0153]
By introducing a mobile terminal having a master key function, it is possible to greatly reduce the number of keys that must be stored by the security guard and reduce the administrative burden.
[0154]
The introduction of a mobile terminal with a master key function eliminates the need for key delivery as in the past, eliminating the need for cumbersome procedures associated with key delivery, and promptly heading to the site to prevent the situation from being picked up and spreading damage. Can be performed.
Although a mobile terminal having a master key function can lock and unlock a plurality of locks like a master key, contract key data used for that purpose is transmitted from the monitoring center as much as necessary when necessary. In the unlikely event that a mobile terminal is stolen or lost, damage can be minimized.
[0155]
The encryption code received from the monitoring center as key data is input to the mobile terminal so that a lock / unlock signal can be generated, which has been used for communication between the monitoring center and security guards or maintenance personnel. Mobile phones and wireless devices can be used as they are, and mobile terminals can be introduced without wasting existing operation systems.
[0156]
It is confirmed that the user of the mobile terminal is a person who has been authorized by the authentication, and that the mobile terminal is also a legitimate mobile terminal by the authentication. The mobile terminal cannot be used by anyone other than those who have been given, and can be prevented from being misused.
[0157]
A portable terminal having a master key function outputs a locking / unlocking signal corresponding to a lock (input means such as a card reader) to be locked / unlocked, or outputs a locking / unlocking signal corresponding to a lock to be locked / unlocked. By connecting an adapter capable of output, different types of locks can be locked and unlocked by the mobile terminal.
[0158]
Compared with the master key used for the cylinder lock, the portable terminal having the master key function of the present invention cannot be easily duplicated. Even if hardware equivalents are made, they cannot be used without key data. The key data is sent to the portable terminal only when a dispatching instruction is given from the monitoring center to the security guard, and since the identity is confirmed by authentication, unauthorized acquisition is difficult. Therefore, it is a very safe key.
[0159]
The electric lock according to the present invention operates according to the locking / unlocking signal output from the mobile terminal, and the functions of the mobile terminal can be used effectively.
[0160]
The electric lock according to the present invention has a play provided between the link mechanism and the gear mechanism of the drive unit, so that when the lock is unlocked and unlocked with a key or the like without using a motor, the lock by the motor is not applied. it can.
