[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an unlocking device and a security system using the same.
[0002]
[Prior art]
Mechanical keys that are widespread in ordinary dwellings have a risk of being easily picked, and have become a social problem. In addition, electronic keys such as a password input method and a fingerprint collation method have become widespread, but a hybrid lock system that is used simultaneously with a mechanical key is ideal for further improving security (security) ( Non-Patent Document 1).
[0003]
This hybrid lock system inserts a hybrid key with a built-in IC chip into a cylinder, and if the code written on the IC chip does not match the code registered on the cylinder, the key may not be pinched on the cylinder. The cylinder does not rotate. Therefore, the security is improved by combining an electronic key with the act of unlocking the cylinder by matching the pin arrangement of the cylinder using a special tool such as picking.
[0004]
However, this method achieves the initial purpose of not unlocking in the event of an actual picking action, but does not judge whether it has been damaged by picking and does not achieve further crime prevention actions such as identifying intruders and repelling .
[0005]
As a method of recognizing a picking action, there is a method of detecting a specific vibration generated at the time of picking, judging that the picking is performed, issuing an alarm with a loud siren, or notifying a designated telephone number (picking alarm HA-11 manufactured by Iwata Electric Co., Ltd. Non-Patent Document 2).
[0006]
However, this method cannot detect a plagiarized duplicate key because the vibration caused by the picking action is detected. In addition, there is a problem of erroneous operation, such as actually operating even with vibration not due to picking action, or not operating even with picking.

[Problems to be solved by the invention]
As described above, the security is improved with the conventional hybrid key, but further security such as identification or repulsion of an intruder cannot be performed. In addition, the conventional picking alarm cannot cope with a plagiarized duplicate key, and there is a problem that the picking alarm may be activated even by vibrations not caused by picking.
[0010]
The present invention has been made in view of the above situation, and has an object to provide an unlocking device having a picking detection system which improves security and does not malfunction, and a security system using the same. I do.
[0011]

[0012]
At this time, the key is a key portion formed with notches or dimples, a tip of the key portion, or an interface of the IC chip formed on the side of the notch or dimple and a holding member formed integrally with the key portion. And the first lock is a cylinder having a fixed pin knitting and an input part therein, and when the pin knitting of the cylinder coincides with the notch or dimple of the key, the first lock locks the holding part. It is preferable that the first lock is unlocked by being rotated, and the interface and the input unit are arranged opposite to each other and coupled.
[0013]
Further, in the present invention, the cylinder of the first lock is formed such that the first cylinder on which the pin knitting is formed and the second cylinder on which the input unit is formed face each other, A first plate that moves linearly in conjunction with the rotational movement of the first cylinder, a second plate that moves linearly in conjunction with the rotational movement of the second cylinder, and an interlocking movement with the first plate A first button that is turned on and off, and a second button that is turned on and off in conjunction with the second plate, wherein when the states of the first button and the second button are equal, Preferably, the first lock is unlocked.
[0014]
Further, it is preferable that a storage device that stores the encrypted personal identification code using the personal identification code as an encryption key is provided, and the external device manages access to the storage device.
[0015]

[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an unlocking device of the present invention and a security system using the same will be described in detail with reference to the drawings. Note that the present invention is not limited to these embodiments, and various selections can be made.
[0017]
(Embodiment 1)
FIG. 1 is a diagram showing the structure of a key according to the present invention. Here, a dimple key is shown, in which an IC chip is embedded at the tip of the key.
[0018]
As shown in FIG. 1, the key 10 includes a key portion 1 having a dimple 5 formed thereon and a holding portion 2 integrally formed with the key portion 1. An IC chip 6 is affixed to the tip of the key portion 1, and the IC chip 6 is divided into a region 3 and a region 4.
[0019]
The area 3 of the IC chip 6 stores a security code A, and the area 4 stores a security code B. Here, instead of making the IC chip 6 into two areas, an IC chip storing the security code A and an IC chip storing the security code B may be arranged side by side and affixed to the tip of the key unit 1.
[0020]
FIG. 2 is a view showing a state where the key 10 shown in FIG. 1 is inserted into a keyhole of the cylinder 16.
[0021]
As shown in FIG. 2A, sensors 8 and 9 are formed behind the keyhole of the cylinder 16. The sensors 8 and 9 are for reading an IC chip attached to the tip of the key 10. Here, the key 10 and the keyhole are shaped so that the upper and lower sides in the inserted state can be uniquely determined. With a normal cylinder key, the center groove extending in the long axis direction of the key can be used as it is, but in the case of a dimple key, such a mechanism needs to be newly created. For example, as shown in FIG. 3, the shape of the tip of the dimple key 10 can be realized by providing a guide portion 11 for uniquely determining the shape in the vertical direction.
[0022]
As shown in FIG. 2A, a sensor 8 for reading only the security code B is disposed at an upper portion in the back of the keyhole, and a sensor 9 for reading only the security code A is provided at a lower portion. Thus, if the key 10 is simply inserted into the keyhole of the cylinder 16, the area 3 storing the security code A faces the sensor 8 that reads only the security code B, and the sensor 9 that reads only the security code A does. Since the areas 4 storing the codes B are opposed to each other, the personal identification codes cannot be read.
[0023]
Next, as shown in FIG. 2B, when the key 10 is rotated and the first lock is mechanically unlocked, the PIN code B is stored in the sensor 8 that reads only the PIN code B. Since the area 4 is opposed to the sensor 9 that reads only the security code A, the area 3 storing the security code A is opposed to the sensor 9, so that the security code can be read.
[0024]
The sensors 8 and 9 are connected to control means 7 such as a CPU, and the control means 7 can couple with the IC chip 6 only when the first lock is unlocked by turning the key 10. In this way, the control means 7 sends a signal for unlocking the electronic second lock when the password stored in the IC chip 6 matches the password held in advance and unlocks the second lock. I do. The sensors 8 and 9 may be electrodes, light-receiving and light-emitting elements, or the like. In this case, the area was divided into two parts so that coupling was not performed unless they corresponded to the sensors 8 and 9, respectively. However, when the key was inserted with one area and one sensor, they were arranged in alternate positions and rotated. It may be arranged at a position facing sometimes.
[0025]
When the encryption key is stored in the IC chip 6 instead of the personal identification code, when the key 10 is rotated, the encrypted personal identification code previously stored in the control device 7 is decrypted. You may collate with the stored personal identification code. At this time, it is preferable that one encryption key is divided and stored in two areas, area 3 and area 4.
[0026]
At this time, as shown in FIG. 4, the control means 7 is connected to the Internet, and the security code decrypted using the encryption key A and the encryption key B read by the sensors 8 and 9 is transmitted through the Internet 12 to the security company 13 or the like. It may be checked against a password managed by the management company.
[0027]
When the encrypted personal identification code is stored in the IC chip 6, the encryption key can be held in the control device 7 or maintained by a security company 13 connected via the Internet 12 as shown in FIG.
[0028]
In either case, the control code 7 decrypts the password A and the password B, and transmits the obtained password to the security company 13 through the Internet 12. This password is collated with the password recorded in the encryption database 14 stored in the server of the security company 13, and if the collation contents match, the collated information is transmitted from the security company 13 to the control means 7, The control means 7 transmits a signal for unlocking the electronic second lock 15 to unlock the second lock 15.
[0029]
As shown in FIG. 4, if the mechanical first lock 18 is installed near the door knob of the door 17 and the electronic second lock is installed above and below the door 17, the door 17 can be mounted with a bar or the like. It becomes difficult to destroy.
[0030]
Here, it is assumed that the key in which the IC chip 6 is not built is illegally copied or the first lock 18 is mechanically unlocked using a special tool such as picking. At this time, since the sensors 8 and 9 cannot collate the personal identification code, the control means 7 detects this and notifies the security company of a signal that could not be collated.
[0031]
As shown in FIG. 5, the security company can transmit an operation command to the security camera device 19 and record an image of a person in front of the keyhole on a server of the security company.
[0032]
Further, even if the first lock 18 is unlocked with the key built in the IC chip, if the encrypted security code cannot be decrypted by the control means 7, a signal is transmitted to the security company or the security camera device is activated. Security processing such as alarming or sounding an alarm may be performed. Also, when the security code to be compared does not match at the security company, the processing may be performed in this manner.
[0033]
Such security processing does not need to use a security company if a home server is used. In addition, the police can directly manage the information, but in a company or the like, the information can be managed in-house.
[0034]
As described above, in the unlocking device of the present invention, it is possible to determine whether or not the unlocking is normal in a state where the first lock is unlocked. The next security device can be reliably operated without the problem described above. In addition, even after the first lock has been illegally unlocked, the electronic second lock is in a locked state, so that unauthorized entry can be prevented.
[0035]
FIG. 8 is a diagram for explaining a mechanism that becomes a hybrid even when locked from the indoor side.
[0036]
As shown in FIG. 8, the cylinder of the first lock is divided into an outdoor cylinder 104 having a keyhole 100 formed therein and a cylinder 105 having a sensor 106 and a knob 101 formed therein. The cylinder 104 on the outdoor side and the cylinder 105 on the indoor side are in a gear state, and are rotated by operating a key or a knob 101.
[0037]
The rotational movement of these cylinders 104, 105 is converted to horizontal linear movement by sawtoothed plates 102, 103 via gears 107, 108.
[0038]
FIG. 9 shows the state of FIG. 8 as viewed from above the plates 103 and 102.
[0039]
As shown in FIG. 9, these two plates 103 and 102 are brought into contact with button A and button B, respectively, or into a non-contact state by rotating the key and knob 101 by 180 °. I do.
[0040]
At the same time, by rotating the knob 101 by 180 °, the vertical relationship of the sensor 106 is also inverted. In this way, a hybrid can be obtained even when locked from the inside.
[0041]
FIG. 10 shows a combination of the states of the buttons A and B in a case where a logic circuit is formed for a mechanism of hybrid locking when locked from the indoor side.
[0042]
As shown in FIG. 10, the first lock may be in the unlocked state when the states of the buttons A and B are equal to 00 or 11, and may be in the locked state when they are not equal to 01 or 10.
[0043]
FIG. 11 shows a case where the IC chip is divided into two and installed on the side surface of the dimple.
[0044]
As shown in FIG. 11, the sensors A and B are also installed separately on the side wall of the cylinder. In this case, if it is used for a door, there is a disadvantage that the lock from inside the room does not become a hybrid, but it is enough to be used as a key for starting an automobile engine.
[0045]
When it is desired to set an expiration date on a key to be used for an apartment or a rental apartment, at least one of the security code A and the security code B of the IC chip attached to the tip of the key is provided with an expiration date. Just do it.
[0046]
FIG. 5 shows an example in which only one of the areas 3 and 4 of the IC chip 6 uses a security code with an expiration date.
[0047]
In this case, after the resident has left the apartment, he has the same key and uses it to unlock the key in the original room. At this time, since this key has an expired password, the second key is not unlocked. In addition, since the landlord has recorded the possession of an indefinite security code, the key that attempted to unlock can be identified immediately.
[0048]
Further, since one password is disabled, the lock cannot be opened after the contract date.
[0049]
Next, another business model using the hybrid lock system will be described.
[0050]
As shown in FIG. 6, a personal computer terminal provided with a keyhole for a hybrid key of the present invention is connected to a database on the broadband Internet.
[0051]
Insert the key into the keyhole and turn it to turn on. At this time, the sensor inside the keyhole activates, reads the encryption key from the IC chip at the tip of the key, decrypts the encryption obtained from the server that manages the database through the broadband Internet, and sends the password obtained by decrypting the encryption to the server. I will send it back. If the password can be verified on the server side, the area on the database owned by the person who inserted the key is used as the hard disk of the personal computer terminal.
[0052]
In this way, if the hybrid key of the present invention is used, any personal computer in the office can be used as its own personal computer with almost the same trouble as turning on the power simply by inserting and rotating the key. Can be.
[0053]
If such a personal computer terminal is installed in an Internet cafe, a hotel, an airplane, an airport, a station, or the like, a personal computer that is used regularly can be used anywhere without carrying a mobile terminal. .
[0054]
When using such a system in an Internet cafe or office, or when standing in a toilet or the like, a screen saver with a password is activated as shown in FIG. The password of this screen saver is linked to the mechanical key, and it is necessary to prevent the user from rotating and removing the key without entering the password.
[0055]
In this way, a hybrid key can be realized in which the electronic lock and the mechanical lock can be unlocked simultaneously with a single key.
[0056]
【The invention's effect】
As described above, according to the present invention, it is possible to provide an unlocking device having a picking detection system which improves security and does not malfunction, and a security system using the same.
