  The problem to be solved by the present invention is to lock the door using a locking device that is unlocked by remote control without providing a keyhole on the outside of the door, and as an identification number, the identification number part and It is an object of the present invention to provide a remote-controlled locking device using a combination of numbers consisting of a random variable number part.

In order to solve the above problem, in the invention of claim 1,
In a remote-controlled locking structure including a locking device attached to the inside of the door and a remote control key for transmitting and receiving a password to and from the locking device outside the door,
The locking device includes a transmitting / receiving unit that transmits and receives a password, a determining unit that determines whether the received password is correct, and a first recording unit that records a current password.
The remote control key includes a transmitting / receiving unit for transmitting / receiving a password, and a second recording unit for recording a password.
An identification number portion that is not changed by a predetermined number of consecutive numbers or characters, and a random variable number portion that includes a combination of numbers or characters other than the identification number portion and whose order is randomly changed. It consists of
If the password transmitted by the remote control key matches the password recorded in the locking device, open and close the locking device, change the combination of numbers or characters in the random variable part of the It is characterized by doing.

In the invention of claim 2,
The password is composed of a combination of 25 numbers, of which the last combination of 5 numbers is fixed to be an identification number section, and the remaining 20 numbers are a random variable number section. The order of the combination of numbers changes each time the locking device is operated.
In the invention of claim 3,
If the identification number part of the password transmitted from the remote control key matches and the random variable number part does not match, the locking device that has received this transmits a currently valid password to the remote control key, and the remote control key receives the password. The security code thus recorded is recorded in the second recording section, and the locking device is opened and closed.
Further, in the invention of claim 4,
The personal identification number is composed of a voice signal, and a telephone or other voice generating means can be used in place of the remote control key.

The remote control locking device of the present invention does not use a cylinder lock, so that a keyhole does not open on the surface of the door, and the locking device can be unlocked by transmitting and receiving a personal identification number. Can be canceled.
The password is composed of a combination of a number of numbers, and after unlocking, the combination is changed except for a fixed predetermined number string, making it difficult to decode and improve security. Can be planned.
Further, since the fixed predetermined number sequence is determined for each locking device, it is not unlocked by a remote control key corresponding to the locking device.

  A preferred embodiment in which the remote control locking device of the present invention is applied to a door of a building will be described below with reference to the drawings.

Inside the door D, a remote control type locking device 1 is fixed.
The locking device 1 has a first transmitting / receiving unit 2 having an antenna 2A for receiving a password from a remote control key, and receives a signal from the first transmitting / receiving unit 2 to determine whether or not the signal matches a correct release signal. Unit 3, an operating unit 4 that operates the locking rod 4A to open and close the lock when it determines that the password is correct, a first recording unit 5 that records the password, and a password generating unit that generates a new password. It consists of six.
On the other hand, the remote control key 11 has a second transmitting / receiving section 12 capable of transmitting / receiving a password to / from the first transmitting / receiving section 2 and a second recording section 15 for recording the password. May be provided.

The security code S used by the locking device 1 and the remote control key 11 includes an identification number part S1 and a random variable part S2 as shown in FIG.
That is, in the case of the present embodiment, the password S is composed of 25 numbers, and the permutation of 5 numbers is fixed, that is, the permutation of the 21st to 25th is fixed, and the identification number part S1 is used. It has become.
In the illustrated example, it is a permutation of five numbers 21, 22, 23, 24, and 25.

The feature of this password is that the password changes each time the remote control key 11 is used, and is named a floating system.
The numbers from 1 to 20 are random variable parts, and the order can be changed. The change in the order can be converted into a combination of 3.2 billion numbers by changing the multiplier.
The permutation of the numbers 21 to 25 is fixed, and serves as an identification number part.

Then, each time the locking device 1 is opened or closed, the order of the numbers is randomly changed to be a password used for the next opening and closing operation.
The numbers of the random variable section S2 except for the five numbers of the identification number section S1 can be changed by using a random number table in the personal identification number generating section.
In the above embodiment, numbers are used, but characters may be used. Here, the characters include symbols and figures.
Then, a signal indicating such a password is transmitted and received using various signals such as infrared rays and radio waves.

Next, the usage will be described.
In the illustrated example, the remote control key 11 is provided with buttons 16 and 17 for opening and closing, respectively. When one of the buttons is turned on, a password is called from the second recording unit 15 and converted into a signal. 2 Transmitted from the transmitting / receiving unit 12.
The transmitted signal of the password is received by the first transmission / reception unit 2 of the locking device 1, and the determination unit 3 determines whether the signal matches the password recorded in the first recording unit 5.
When all of the 25 passwords match, the operating unit 4 operates to move the lock rod 4A in and out, and lock or unlock.

Further, the locking device 1 generates a new (to be used next) security code when the security code generation unit 6 matches the security code, records the security code in the first recording unit 5, and performs the first transmission / reception. The data is transmitted from the unit 2 to the second transmitting / receiving unit 12 of the remote control key 11.
The remote control key 11 resets the used password and records a new password in the second recording unit 15.
The new password is a password in which the random variable portion has been changed as described above.
As a result, the locking device 1 uses a different password for each opening and closing.

If the received passwords do not match, the operating unit 4 remains stopped, so that the lock 4A cannot be moved.
Further, since there is no keyhole for the cylinder lock on the surface of the door D, the door cannot be pry off, and the safety is extremely high.

Next, when a plurality of remote control keys 11 are set in one locking device 1, the password of the remote control key 11 not used last time differs from the current password stored in the locking device 1. I have.
However, in the determination unit 3, the identification number part S 1, which is a fixed sequence of numbers, of the personal identification numbers transmitted by the remote control key 11, identifies the personal identification number recorded in the first recording unit 5 of the locking device 1. It is determined whether or not the numbers match the numbers. If the numbers match, the operating unit 4 is operated to open and close the lock even if the numbers in the random variable unit S2 do not match.

At the same time, a new password can be recorded in the second recording unit 15 of the remote control key 11 via the first and second transmitting / receiving devices 2 and 12.
Thereby, even if a plurality of remote control keys 11 are set in one locking device 1, it can be used without any trouble.

  In the above embodiment, the password is generated by the password generating unit 6 of the locking device and transmitted to the remote control key 11 for recording. However, as shown by the dotted line in the figure, the password is also generated by the remote control key 11. 16 may be provided to generate and record a new personal identification number by itself, and if the personal identification numbers do not match, the personal identification number may be reset and rewritten with the personal identification number from the locking device 1. .

In this embodiment, the remote control key 11 is used for both unlocking and locking. However, the remote control key is used only for unlocking, and locking is automatically performed when the door D is closed. Good.
In other words, it goes without saying that various design changes can be made without departing from the gist of the present invention.

Since the locking device 1 is mounted inside the door D, there is no need to provide a keyhole for a cylinder lock on the surface of the door D. Further, since the mounting position of the locking device 1 is not limited, the locking rod 4A is externally provided. Since the position cannot be estimated, the antitheft effect is high.
Further, the structure of the door of the present invention is not particularly limited, and the door of the present invention can cope with a left-right door.
The locking device 1 and the remote control key 11 have an IC and a small battery built therein. When the battery runs out, the remaining amount is notified by blinking an LED or the like, but when the battery runs out, the locking device is opened. Is set as follows.

Further, the registration of the personal identification number to the remote control key can be performed with a single touch because a new personal identification number is generated only by clearing the registered personal identification number.
In addition, in this case, by installing a separate kit, it can be opened and closed by telephone and voice input is also possible.
The number of locking rods is not particularly limited, and one, two, or other plurality of locking rods may be provided.
Further, in the present invention, the locking device for the door of the building has been described, but it can be used as a locking device for a car.
In other words, various design changes can be made without departing from the gist of the present invention.
