Has a function of receiving an e-mail via the Internet. An external control unit 211 for controlling the information management system 201 from the outside is provided in a house 210 of a general household in which the door 200 is an entrance door.
[0022]
The door 200 incorporates an information management system 201, an e-mail transmission device 202, an infrared sensor 203, and a switch 204, and is configured to be locked or unlocked by a physical key 205. The physical key 205 is locked or unlocked by electrical control by the information management system 201, and the structure itself is publicly known (for example, see FIG. 5 and FIG. 6 of Patent Document 1). Disclosed structure).
[0023]
In addition, key information can be exchanged by infrared communication 113 by infrared ports of mobile phones 101 to 103 and an infrared sensor 203 attached to door 200. Note that the infrared sensor 203 is operable only for a certain period of time after being turned on by the switch 204, and automatically returns to a non-operation state (initial state) after a certain period of time.
[0024]
FIG. 2 is a detailed configuration diagram of an example of the door 200 and the inside 210 of the house in FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals. 2, the door 200 includes an information management system 201, an e-mail 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, the management of the number of home workers and the issuance of a home key described later are performed. , And mainly performs key collation. Further, it is also connected to an external control unit 211 for controlling the information management system 201 in a house. The e-mail transmitting device 202 directs the absence key (310 in FIG. 3) issued from the information management system 201 when the number of resident persons becomes zero to the mobile phones 101 to 103 (FIG. 1) registered in this system. This is a device that sends a call.
[0026]
The switch 204 is for setting the infrared sensor 203 in a receivable state. As described above, the physical key 205 is electrically controlled and operates 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 user goes out with the mobile phone left at home. The sensor 207 is a sensor that monitors entry and exit of a person. Using the sensor 207, the number of resident persons is managed and monitored in the information management system 201. The external control unit 211 is located in the house 210 and is used to input initial settings or to work with the information management system 201 from the inside to unlock the key 205 when visiting.
[0027]
This embodiment is characterized in that 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, the key information is transferred to the infrared sensor 203 attached to the door 200 by the infrared communication 113 using the infrared communication function of the mobile phone 101 with the infrared function. The control allows the physical key 205 to be unlocked.
[0028]
Here, the key information transmitted by the infrared communication 113 is composed of three types. FIG. 3 shows details of the above three types of key information. The first key is key information based on the e-mail address of the mobile phone (hereinafter, referred to as a mail key). This mail key is different for each user, and here, mail keys 306, 307, and 308 are given to users A, B, and N.
[0029]
The second key is a password determined by the people (residents) living in the house (hereinafter referred to as family keys). The family key 309 is a key common to the people living in the house. The family key 309 is transmitted by infrared rays when the user manually operates the mobile phone when the door 200 is unlocked. These two types of keys (that is, the mail key and the family key) are registered in the information management system 201 built in the door 200, and are always fixed as shown by 301 in FIG.
[0030]
The third key is a password (hereinafter referred to as an absent key) issued when no one is at home. The absence key 310 has a different value each time it is issued, as indicated by 302 in FIG. The absent key 310 is the user 303, the user 304, and the user who have registered both the mail key 306, 307, 308 and the family key 309 via the Internet 104 when the door 200 is closed while no one is at home. Automatically sent to 305 using email.
[0031]
The condition for opening the door 200 is the presence or absence of a resident. When there is a resident, the mail key and the 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 when there is no resident at home.
[0032]
Next, the operation of the present embodiment will be described in detail in three cases: pre-processing, when the door is closed (locked) and when it is opened (unlocked).
[0033]
[Pre-processing]
First, the pre-processing will be described with reference to the flowchart of FIG. By operating the external control unit 211 shown in FIG. 2, input for initial setting is started (step S1). First, the number of resident persons is input with the door 200 closed (step S2). Subsequently, a password (family key) serving as 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 registration of the mail key is repeated until there are no more registrants (step S5). All 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 is prepared so that a mail key and a family key can be transmitted by infrared rays. In addition to this mechanism, the absence key can be entered.
[0034]
[When locked]
Next, the process at the time of locking will be described with reference to the flowchart of FIG. First, an outsider opens the door 200 shown in FIGS. 1 and 2, goes out, and closes the door 200 (steps S11 and S12). At this time, the sensor 207 detects entry and exit, and notifies the information management system 201 of entry and exit of the person. The information management system 201 determines the presence or absence of a resident from the relationship between the initially set resident and the number of times of entering and leaving (step S13).
[0035]
Here, when it is determined that there is no resident, the information management system 201 issues an absence key (step S14). The absence key is sent from the information management system 201 to the e-mail transmission unit 202, and further transmitted through the home LAN (Local Area Network) 212 and the Internet network 104 in FIG. The data is transmitted by e-mail to 301 to 303 in FIG. 1 (step S15). Thereafter, the information management system 201 locks the door 200 with the physical key 205 (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 absence key.
[0036]
On the other hand, when the information management system 201 determines that there is a resident at step S13, the physical key 205 operates and the key is activated (step S17). Therefore, no e-mail is sent in this case. In this case, two keys required to open the door are the mail key and the 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 pressed to operate the infrared sensor 203 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 locked door 200 by 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 rays from the mobile phone 101, but the family key is manually operated by the user of the mobile phone 101 according to the display on the display unit of the mobile phone 101, for example. To send infrared light.
[0038]
Thus, the infrared sensor 203 receives the two types of key information, and supplies the received two types of key information to the information management system 201 (step S23). The reason for manually transmitting the family key is that automatically transmitting the family key prevents the third party from opening the door 200 when the mobile phone 101 is stolen or found by a third party. To do that.
[0039]
The information management system 201 sequentially checks the mail key and the family key in the input received key information (steps S24 and S25). When both the mail key and the family key match the mail key and the family key registered in the information management system 201 in advance, the information management system 201 determines whether or not there is an absence key (step S26). When there is no home, that is, when there is a resident, the door 200 is opened at this time (step S28).
[0040]
On the other hand, when there is an absent key, that is, when no one is at home, the information management system 201 collates the absent key registered in advance with the absent key in the received key information (step S27). If they match, the information management system 201 unlocks the door 200 (step S28).
[0041]
Thereby, 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. This is sensed (step S31), and the fact is notified to the information management system 201, and the information management system 201 calculates the number of resident persons (step S32). Once the door 200 has been opened using the absence key, the absence key cannot be used again.
[0042]
If the registered key information does not match the received key information in any of the comparisons in steps S24, S25, and S27, the door 200 cannot be opened because the received key information is not valid key information ( Step S29).
[0043]
As described above, according to the present embodiment, a different absence key 310 is issued each time a house is absent, which can lead to enhanced security. Also, when the door 200 is closed in a state where no one is at home, the absence key 310 is sent to the users 303 to 305 who have registered both the mail keys 306 to 308 and the family key 309 via the Internet network 104 by e-mail. , The users 303 to 305 can obtain the information of the absence key 310 anytime and anywhere (even if the registered user is out of the service area when the absence key 310 is transmitted, the user must be within the service area). Email can be received).
[0044]
Furthermore, according to the present embodiment, an increase in luggage when going out can be prevented by giving a key function to a mobile phone carried when going out. Further, by manually inputting the family key and transmitting it by infrared rays, unauthorized opening of the door by a third party who has stolen or found the mobile phone can be prevented. Further, 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 transmitting means. Can reduce the damage of unauthorized unlocking.
[0045]
Next, a second embodiment of the present invention will be described. FIG. 7 shows a system configuration diagram of a second embodiment of the lock control system according to the present invention. The first embodiment is an example of controlling the unlocking or locking of the lock 205 of the door 200 of a general apartment or condominium, but the present embodiment is directed to unlocking or opening the door of the safe or the locker 404. It is an example of locking control.
[0046]
In FIG. 7, a safe (or locker) 404 is provided with an infrared sensor 406 on a door 405. The control unit 407 is provided with the configuration of the door 200 in FIG. 2 excluding the infrared sensor 406. Although the control unit 407 is provided outside the door 405 in FIG. 7, the control unit 407 may be provided inside the door 405. An e-mail address A (corresponding to a mail key according to the first embodiment) and a user common password B (corresponding to a family key according to the first embodiment) are registered in the control unit 407 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 absence key of the first embodiment), and the key is locked. The key information C is newly issued each time the door is closed, and is registered in the e-mail transmission device in the control unit 407 provided in the safe (or locker) 404 and registered in the E-mail of the mobile phones 401, 402, and 403 with infrared function. Sent to an email address.
[0048]
At the time of unlocking thereafter, the key information of these three types (E-mail address A, user common password B, and key information C) is sent to the infrared sensor 406 provided in the safe (or locker) 404 and the mobile phone 401 with the infrared function. , 402 and 403, the door 405 of the safe (or locker) 404 is opened by transmitting from the mobile phone (401 in the example of FIG. 7) owned by the user to be unlocked using the infrared communication function. be able to. Also in the present embodiment, the user common password B is transmitted by infrared rays through manual operation of the user. 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. 6, the same components as those of FIG. 6 are denoted by the same reference numerals, and the description thereof will be omitted. The present embodiment has the same hardware basic configuration as 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 authentication of the mail key, the family key, and the absence key fails in 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 a set number N (step S35). If the number of failures is less than N, an initial state is set (step S36). In this initial state, the infrared sensor 203 has returned to the non-operating state. Therefore, when unlocking, the switch 204 is turned on again (ON) to put the infrared sensor 203 into the operating state.
[0051]
On the other hand, when the number of authentication failures becomes N or more, it is determined that the suspicious individual has attempted to unlock, and the information control system 201 of FIG. Is transmitted to the security company or the police in which is set (step S38). This makes it possible to further enhance security as compared with the first embodiment.
[0052]
Note that 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 not limited to the infrared communication, and may be an external device that exists as a function of the mobile phone such as Bluetooth. It is also possible to substitute for short-range wireless communication with. Further, four or more types of keys can be used. Further, the second and third embodiments can be combined.
[0053]
【The invention's effect】
