Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lock control system, and more particularly to a lock control system that unlocks or locks a door key (lock) by remote control from a mobile terminal such as a mobile phone.
[0002]
[Prior art]
Recently, locks on front doors of condominiums often encounter damage such as picking, which has become a social problem. For this reason, it is very important from the viewpoint of security to propose a key for opening a door in addition to the physical key currently used most frequently. In view of this, a lock control system using a mobile phone has been proposed that has rapidly spread in recent years and is associated with a mobile phone, which is a tool owned by many people and carried when going out, and a key (for example, Patent Document 1). reference).
[0003]
FIG. 9 shows a system configuration diagram of an example of a conventional lock control system described in Patent Document 1. In the figure, an electric lock 908 is attached to a door 907 such as a front door in a general household 900, and a cellular phone 901 is used from the outside to unlock the electric lock 908. When a call is made to 905, the call signal is transmitted to the switching center 903 via the mobile phone base station 902 and the public network 904. When receiving the call signal, the switching center 903 transmits the incoming signal to the telephone 905 of the general home 900 that is the call destination via the public network 904.
[0004]
When the telephone 905 receives this incoming signal, the telephone number of the mobile phone included in the incoming signal is recognized, and the recognized incoming telephone number is transmitted to the control device 906 of the electric lock 908. The control device 906 compares the incoming telephone number with a predetermined telephone number of a mobile phone carried by a specific unlocking licensee, and outputs an unlock signal to the electric lock 908 if they match. Thus, the electric lock 908 is remotely operated to unlock.

[Problems to be solved by the invention]
However, the conventional lock control system described in Patent Document 1 has the following problems. The first problem is that there is a risk of erroneous unlocking. In other words, in the case of a tool that is always carried around, such as a mobile phone, there is a risk of making a mistaken call to the home due to some shock (because a call is made with a few button operations by a shortcut, etc.). This mistake will cause the door to be unlocked.
[0007]
The second problem is that the information used as a key is only an incoming call. That is, in the conventional lock control system, the telephone number of the mobile phone included in the incoming signal is recognized and only compared with the telephone number of the mobile phone carried by the specific unlocking licensee stored in advance, If the verification results match, the lock will be unlocked. From the viewpoint of security, it is convenient if a double or triple lock can be applied.

Further, key information can be exchanged by infrared communication 113 by the infrared ports of the mobile phones 101 to 103 and the infrared sensor 203 attached to the door 200. The infrared sensor 203 is operable only for a certain period after being turned on by the switch 204, and automatically returns to a non-operational state (initial state) after a certain period of time has elapsed.
[0024]
FIG. 2 is a detailed configuration diagram of an example of the door 200 and the house 210 in FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals. In FIG. 2, the door 200 includes an information management system 201, an email transmission device 202, an infrared sensor 203, a switch 204, a physical key 205, an external input device 206, and a sensor 207.
[0025]
The information management system 201 is connected to an e-mail transmission device 202, an infrared sensor 203, a physical key 205, an external input device 206, and a sensor 207. Here, management of the number of at-home people and issuance of home keys to be described later The key verification is mainly performed. Moreover, it is connected also to the external control part 211 for controlling the information management system 201 in a house. The e-mail transmitting apparatus 202 directs the absent key (310 in FIG. 3) issued from the information management system 201 when the resident is zero to the mobile phones 101 to 103 (FIG. 1) registered in this system. The device that sends
[0026]
The switch 204 is for making the infrared sensor 203 in a receivable state. As described above, the physical key 205 operates under electrical control based on a command to close or open the door 200 from the information management system 201. The external input device 206 is used to input key information when the mobile phone is left at home. The sensor 207 is a sensor that monitors the entry and exit of people. This sensor 207 is used to manage and monitor the number of people at home in the information management system 201. The external control unit 211 exists in the house 210, and is used to input initial settings or to act on the information management system 201 from inside and unlock the key 205 when visiting a customer.
[0027]
In this embodiment, an infrared communication function, which is one function of the mobile phones 101 to 103, is used as a key function for unlocking the door 200. That is, in FIG. 1, by using the infrared communication function of the mobile phone 101 with an infrared function, key information is transferred to the infrared sensor 203 attached to the door 200 by the infrared communication 113, so that the information management system 201 The physical key 205 can be unlocked by the control.
[0028]
Here, the key information transmitted by the infrared communication 113 includes three types. FIG. 3 shows details of the above three types of key information. The first key is key information (hereinafter referred to as a mail key) based on the e-mail address of the mobile phone. This mail key is different for each user, and here, mail keys 306, 307, and 308 are given to users A, B, and N, respectively.
[0029]
The second key is a password (hereinafter referred to as a family key) determined by a person living in the house (resident). This family key 309 is a key common to humans living in the house. The family key 309 is transmitted by infrared rays by manual operation of the user's mobile phone when the door 200 is unlocked. These two types of keys (that is, a mail key and a family key) are registered in the information management system 201 built in the door 200, and are always fixed as indicated by 301 in FIG.
[0030]
The third key is a password (hereinafter referred to as an absent key) that is issued when there is no resident in the house. The absent key 310 has a different value each time it is issued, as indicated by 302 in FIG. The absent key 310 is a user 303, a user 304, a user who registered both the mail keys 306, 307, 308 and the family key 309 via the Internet 104 when the door 200 is closed with no people in the house. Automatically sent to 305 using e-mail.
[0031]
The condition for opening the door 200 is the presence or absence of a person at home. When there is a resident, an email key and a family key are transmitted by infrared, and when there is no resident, all three types of keys are transmitted by infrared. The number of keys is increased and the security is strengthened compared to when there is no resident.
[0032]
Next, the operation of the present embodiment will be described in detail by dividing it into three cases: preprocessing, when the door is closed (when locked), and when the door is opened (when unlocked).
[0033]
[Pre-processing]
First, pre-processing will be described with reference to the flowchart of FIG. The external control unit 211 shown in FIG. 2 is operated to start input for initial setting (step S1). First, the number of people at home with the door 200 closed is input (step S2). Subsequently, a password (family key) that is a common key for the person using the door 200 is set (step S3). Next, the user's mail address (mail key) is registered (step S4). The mail key registration is repeated until there are no other registrants (step S5). All of the registered information is stored in the information management system 201 shown in FIGS. On the other hand, as a setting on the mobile phone side, a setting that enables infrared transmission of a mail key and a family key is prepared. In addition to this mechanism, you can enter the absent key.
[0034]
[When locked]
Next, the process at the time of locking is demonstrated with reference to the flowchart of FIG. First, a person who goes out opens the door 200 shown in FIGS. 1 and 2 and goes out, and then closes the door 200 (steps S11 and S12). At this time, the sensor 207 detects the entry / exit and notifies the information management system 201 of the person's entry / exit. The information management system 201 determines whether or not there is a home based on the relationship between the initially set home and the number of times of entering and exiting (step S13).
[0035]
Here, if it is determined that there is no resident, the information management system 201 issues an absent key (step S14). This absent key is sent from the information management system 201 to the e-mail transmission unit 202, and through the home LAN (Local Area Network) 212 and the Internet 104 in FIG. It is transmitted using e-mail toward 301 to 303) in FIG. 1 (step S15). Thereafter, the information management system 201 places a physical key 205 on the door 200 (step S16). In this case, there are three types of keys required to open the door first: a mail key, a family key, and an absent key.
[0036]
On the other hand, when the information management system 201 determines that there is a person at home in step S13, the physical key 205 operates as it is and the key is locked (step S17). Accordingly, in this case, no e-mail is transmitted. In this case, there are two keys required to open the door: a mail key and a family key.
[0037]
[When unlocked]
Next, the unlocking process will be described with reference to the flowchart of FIG. First, the switch 204 of the door 200 shown in FIGS. 1 and 2 is pushed, and the infrared sensor 203 is operated for a certain period (step S21). Next, key information is transmitted to the infrared sensor 203 of the door 200 from the short distance outside the door 200 in the locked state using the infrared function of the mobile phone 101 shown in FIG. 1 (step S22). At this time, the mail key is automatically transmitted by infrared from the mobile phone 101, but the user of the mobile phone 101 manually operates the family key stored in the mobile phone 101 according to the display on the display unit of the mobile phone 101, for example. To send by infrared.
[0038]
Thereby, the infrared sensor 203 receives two types of key information, and supplies the received two types of key information to the information management system 201 (step S23). The reason why the family key is manually transmitted is that when the family key is automatically transmitted, when the mobile phone 101 is stolen or picked up by a third party, the door 200 is prevented from being opened by the third party. It is to do.
[0039]
The information management system 201 sequentially collates the mail key and family key in the input reception key information (steps S24 and S25). When both of these mail key and family key match the mail key and family key registered in advance in the information management system 201, the information management system 201 determines the presence or absence of the absent key (step S26). When there is no person, that is, when there is a person at home, the door 200 is opened at this point (step S28).
[0040]
On the other hand, when there is an absent key, that is, when there is no resident, the information management system 201 compares the absent key registered in advance with the absent key in the received key information (step S27). If the two match, the information management system 201 unlocks the door 200 (step S28).
[0041]
As a result, when the user carrying the mobile phone 101 opens the door 200 and enters the house, and closes the door 200 (step S30), the sensor 207 shown in FIG. 2 enters the house. This is detected (step S31), and the information management system 201 is notified to that effect, and the information management system 201 is made to calculate the number of people at home (step S32). Once the door 200 is opened using the absent key, the absent key cannot be used again.
[0042]
If the registered key information and the received key information do not match at any of the verifications in steps S24, S25, and S27, the door 200 cannot be opened because the received key information is not regular key information ( Step S29).
[0043]
As described above, according to the present embodiment, since a different absent key 310 is issued every time when the house is absent, security can be enhanced. The absent key 310 is used to send an e-mail to the users 303 to 305 who have registered both the mail keys 306 to 308 and the family key 309 via the Internet 104 when the door 200 is closed with no people in the house. Therefore, the users 303 to 305 can obtain the information of the absent key 310 anytime and anywhere (even if the registered user is out of the service area when transmitting the absent key 310, the user 303 to 305 can always obtain the information. Mail can be received).
[0044]
Furthermore, according to the present embodiment, it is possible to prevent an increase in baggage when going out by providing a key function to the mobile phone carried when going out. Further, by manually inputting the family key and transmitting it by infrared rays, it is possible to prevent unauthorized opening of the door by a third party who has stolen or picked up the mobile phone. Furthermore, according to the present embodiment, a key without a keyhole can be used as the key 205 by using the infrared transmission function attached to the mobile phone as the key information transmission means. Can reduce the damage caused by unauthorized unlocking.
[0045]
Next, a second embodiment of the present invention will be described. FIG. 7 shows a system configuration diagram of the second embodiment of the lock control system according to the present invention. The first embodiment is an example of the unlocking or locking control of the lock 205 of the door 200 of a general apartment or condominium, but this embodiment does not unlock the door of the safe or the locker 404. It is an example of control of locking.
[0046]
In FIG. 7, a safe (or locker) 404 is provided with an infrared sensor 406 on a door 405. Further, the control unit 407 is provided with the configuration of the door 200 in FIG. 2 excluding the infrared sensor 406. In FIG. 7, the control unit 407 is provided outside the door 405, but may be provided inside the door 405. In the control unit 407, an e-mail address A (corresponding to the mail key of the first embodiment) and a user common password B (corresponding to the family key of the first embodiment) are registered in advance. .
[0047]
Further, when the door 405 of the safe (or locker) 404 is closed, the control unit 407 issues key information C (corresponding to the absent key in the first embodiment), and a mechanism for locking the key is applied. The key information C is newly issued every time the door is closed, and is registered from the e-mail transmission device in the control unit 407 provided in the safe (or locker) 404, and the E of the mobile phones 401, 402, and 403 with infrared function. Sent to an email address.
[0048]
At the time of subsequent unlocking, these three types of key information (e-mail address A, user common password B, and key information C) are sent to the infrared sensor 406 provided in the safe (or locker) 404 and the mobile phone 401 with infrared function. , 402, and 403, the door 405 of the safe (or locker) 404 is opened by transmitting using the infrared communication function from the mobile phone (401 in the example of FIG. 7) owned by the user to be unlocked. be able to. In this embodiment as well, the user common password B is transmitted by infrared light by a user's manual operation. This embodiment also has the same features as the first embodiment.
[0049]
Next, a third embodiment of the present invention will be described. FIG. 8 shows a flowchart of the third embodiment of the lock control system according to the present invention. In the figure, the same components as those in FIG. 6 are denoted by the same reference numerals, and the description thereof is omitted. This embodiment has the same basic hardware configuration as that of the first embodiment, but is characterized in that the information management system 201 operates according to the flowchart of FIG.
[0050]
In FIG. 8, the door cannot be opened when any one of the three types of keys, the mail key, the family key, and the absent key, fails in the authentication (steps S24, S25, S27, S29). Subsequently, the number of authentication failures is counted, and it is determined whether or not the number of failures is equal to or greater than the set number N (step S35). When the number is less than N, an initial state is set (step S36). In this initial state, since the infrared sensor 203 has returned to the non-operating state, when unlocking, the switch 204 is turned on again (ON), and the infrared sensor 203 is in the operating state.
[0051]
On the other hand, when the number of authentication failures is N times or more, it is determined that the suspicious person is trying to unlock, and the information control system 201 in FIG. Is sent to the security company or police set in the mail to notify that the unlocking operation has been performed many times (step S38). As a result, the security can be further enhanced as compared with the first embodiment.
[0052]
The present invention is not limited to the above embodiment. For example, the communication means between the mobile phone 101 and the door 200 is an external device that exists as a function of a mobile phone such as Bluetooth in addition to infrared communication. It is also possible to substitute for short-range radio. Also, four or more types of keys can be used. It is also possible to combine the second and third embodiments.
[0053]
【The invention's effect】
As described above, according to the present invention, when the door is unlocked, the mobile terminal transmits a plurality of key information using the short-range communication function, is received by the receiving means, and is stored in advance by the management means. When the door is unlocked when a matching result is obtained in which the plurality of pieces of key information and the plurality of pieces of key information received by the receiving means all match, a specific state such as the absence of a resident in the building In this case, the predetermined key information transmitted to the mobile terminal by e-mail is included in the plurality of key information transmitted by the mobile terminal using the short-range communication function at the time of unlocking. The security can be further improved as compared with the key information.
[0054]
In addition, according to the present invention, since the key information is transmitted from the portable terminal using the short-range communication function represented by infrared communication, it is possible to prevent a malfunction that the door is unlocked due to a mistaken telephone due to some shock. .
[0055]
