BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for a building door lock, and more particularly to a device for automatically unlocking a house door lock.

[0002]

2. Description of the Related Art Generally, a door lock of a building such as a house is locked and unlocked by inserting a mechanical key into a keyhole provided in the door and rotating the door.

However, in recent years, an electronic key system using an ID code has been proposed for the purpose of improving security. This electronic key system includes an electronic key on which a predetermined ID code is recorded, and an electronic lock for reading the ID code. As such an electronic key system, there is a system in which an electronic key is read by contacting an electronic key with a card reader provided in the electronic lock. In addition, there is a so-called remote key system in which a transmission button provided on an electronic key is pressed to transmit a wireless signal including an ID code from the electronic key to the electronic lock and read the ID code into the electronic lock. In each case, the electronic lock compares the read ID code with a preset ID code, and unlocks the door lock when the ID codes match.

In a remote key system, an electronic key is driven by a built-in battery. For this reason, when the battery runs out, the electronic key does not operate, and it has been necessary to lock and unlock the electronic lock using a conventional mechanical key. However, in this method, a mechanical key that is not normally used must always be carried in preparation for when the battery of the electronic key runs out, which impairs the convenience of the electronic key. Therefore, it is desired to add a function for unlocking the electronic lock to the remote key system even when the battery of the electronic key runs out.

[0005] From such a viewpoint, an electromotive force is generated in the electronic key by bringing the electronic key close to the electronic lock, and a function of operating the electronic key using the electromotive force, that is, a transponder function is added to the remote key system. It is also possible. According to this, since the door lock can be unlocked by electronic ID collation, it is not necessary to carry a mechanical key.

However, in order to add a transponder function to the remote key system, it is necessary to provide a transponder control unit having a dedicated ID code (transponder code) on the electronic key. Further, in order to unlock the electronic lock by the transponder function, it is necessary to set the transponder code to the electronic lock. That is, in order to use the electronic key, it is necessary to set an ID code required for a normal unlocking operation and a transponder code required for an unlocking operation by a transponder in the electronic lock. Therefore, for example, when the electronic lock can be unlocked and unlocked with a new electronic key, it is necessary to register each code in the electronic lock by performing an individual operation, and the registration work becomes complicated. There is a point.

Next, a basic locking and unlocking operation of the door locks 7 and 8 by the remote control device 1 configured as described above will be described. FIG. 6 shows an outline of this operation in chronological order. When the remote control device 1 operates, first, the transmitting / receiving device 1
2 from the transmission / reception antennas 4a and 5a.
, A request signal is output intermittently. This request signal is constantly output during the operation of the remote control device 1.

When the portable device 11 enters the predetermined area A1, A2 and receives a request signal, it automatically transmits an ID code signal in response to the request signal. That is,
When a family member carrying the portable device 11 approaches the door 3,
The ID code signal is automatically transmitted from the portable device 11. The portable device 11 is normally in a standby mode for receiving a request signal, and transmits an ID code signal only when receiving the request signal.

Upon receiving the ID code signal, the transmitting / receiving device 12 converts the ID code contained in the ID code signal into
The ID code is compared with an ID code recorded in advance. And
When the ID codes match, the door lock 7,

To lock. Therefore, the door locks 7 and 8 are
It is automatically locked just by moving away from it. That is, the family member does not need to perform any operation for locking the door locks 7 and 8. Therefore, according to the remote control device 1, the door locks 7 and 8 can be locked and unlocked without performing any operation. The microcomputer 24 is provided with door locks 7 and 8.
At the time of unlocking and locking, a signal is output to the display unit 6, and the fact that the unlocking or locking is performed is displayed on the display unit 6. In this embodiment, the display unit 6 includes two LEDs having different colors. One LED is turned on when the door locks 7 and 8 are unlocked, and the other LED is turned on when the door locks 7 and 8 are locked. It has become so.

When the input circuit 18 operates, a manual operation signal is transmitted from the portable device 11 to the transmitting / receiving device 12.
The manual operation signal includes a signal for unlocking or locking the door locks 7 and 8 with priority. When receiving the manual operation signal, the transmission / reception device 12 unlocks or locks the door locks 7 and 8 with priority. For this reason, when the unlocking operation is performed by the operation keys constituting the input circuit 18, even if the portable device 11 is in the predetermined area A1, A
The door locks 7 and 8 are unlocked even if they are outside. When the locking operation is performed, the portable device 1
Even if 1 is in the predetermined areas A1 and A2, the door locks 7 and 8 are locked.

When unlocking the door locks 7 and 8 by the mutual communication between the portable device 11 and the transmission / reception device 12, the portable device 11 is driven by electric power supplied from a built-in battery (not shown). . For this reason, when the battery of the portable device 11 is exhausted, the unlocking operation based on the basic operation described above cannot be performed. Therefore, the unlocking operation of the door locks 7 and 8 when the battery of the portable device 11 runs out will be described. An outline of this operation is shown in chronological order in FIG.

When the portable device 11 runs out of battery,
First, the mode switch 9 is pressed while the portable device 11 is close to the outdoor antenna unit 4. Thereby, the transmitting / receiving device 12 switches from the normal mode to the transponder mode. Specifically, the transmitting / receiving device 12 stops outputting the request signal and starts outputting the transponder driving radio wave. In this embodiment, the mode is switched to the transponder mode by pressing the mode changeover switch 9 for a predetermined time (for example, three seconds).

As shown in FIG. 3, the transponder driving radio wave is modulated by the transmitting circuit 21 into a radio wave having the same frequency as the request signal, and is output to the predetermined area A3 via the transmitting and receiving antennas 4a and 5a. The effective area of the predetermined area A3 is up to a distance of about 0.1 m from the antenna units 4 and 5, and the request signal output areas A1, A
2 is set. Further, while the request signal is output intermittently, the transponder driving radio wave is output continuously. In this state, if the portable device 11 is located within the transponder driving radio wave output area A3, an induced electromotive force is generated in the portable device 11 by electromagnetic induction of the transponder driving radio wave. Then, the transponder control unit 15 is driven by this electromotive force, and a transponder signal is output.

The transmission / reception device 12 receives the transponder signal by the transmission / reception antenna 4a, and checks the transponder code included in the signal and the transponder code recorded in the memory 24a. When the codes match, a drive signal is output to the door locks 7 and 8, and the door locks 7 and 8 are unlocked.

Therefore, even if the battery of the portable device 11 is exhausted, the door locks 7, 8 are automatically unlocked as in the normal state. That is, by bringing the portable device 11 close to the outdoor antenna section 4, the door locks 7, 8 can be automatically unlocked even when the battery of the portable device 11 is exhausted.
The door locks 7 and 8 are automatically locked when the door 3 is closed after being opened once.

By the way, the door lock 7,
In order to automatically lock and unlock 8, the ID code and transponder code of the portable device 11 need to be registered in the memory 24 a of the microcomputer 24 of the transmitting / receiving device 12. Therefore, the operation of registering each code will be described.
FIG. 8 shows the outline of this operation in chronological order.

At the time of registering such codes, the portable device 11 is first brought close to the indoor antenna unit 5. In particular,
The portable device 11 is located in the output area A3 of the transponder driving radio wave on the indoor side. Then, the registration switch 10 provided in the indoor antenna unit 5 is pressed. As a result, the transmission / reception device 12 switches from the normal mode to the registration mode, and the code can be written into the memory 24a.
In this embodiment, the mode is switched to the registration mode by pressing the registration switch 10 for a predetermined time (for example, three seconds).

The transmitting / receiving device 12 first outputs a request signal. Upon receiving the ID code signal from the portable device 11 in response to this, the transmitting / receiving device 12 stores the ID code included in the ID code signal in the memory 24a.
To record.

Next, the transmitting / receiving device 12 outputs a transponder driving radio wave. Upon receiving the transponder signal from the portable device 11 in response to this, the transmission / reception device 12 records the transponder code included in the transponder signal in the memory 24a. That is, the portable device 11
ID code and transponder code set in
The data is automatically and sequentially recorded in the memory 24a. In other words, the ID code and the transponder code are recorded in the memory 24a by one registration operation.

Therefore, the transmission / reception device 12 checks the transmission signal from the portable device 11 based on the recorded (registered) ID code and transponder code. Therefore, the door locks 7 and 8 can be unlocked only by the portable device 11 in which each code is recorded (registered). When the mode is switched to the registration mode or when the registration is completed, both LEDs of the display unit 6 are turned on for a predetermined time.

Therefore, according to the present embodiment, the following effects can be obtained. (1) When the portable device 11 is out of battery, the transceiver 12 is switched to the transponder mode by pressing the mode changeover switch 9, and the transponder driving radio wave is output from the outdoor antenna unit 4.

(3) The registration switch 10 is turned ON for a predetermined time or more.
When N, the transmitting / receiving device 12 switches to the registration mode. In other words, even if the registration switch 10 is momentarily turned on, the transmitting / receiving device 12 does not switch to the registration mode. Therefore, the registration switch 10 is turned on by mistake.
An erroneous operation in which the transmission / reception device 12 enters the registration mode when N is set can be prevented.

(4) The transmission / reception device 12 switches to the transponder mode when the mode switch 9 is pressed. In other words, when switching to the transponder mode, it is only necessary to press the mode switch 9.
