Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input device used in a door lock system for unlocking a door by an electronic method.

[0002]

2. Description of the Related Art This type of door lock system is widely used in public accommodations such as hotels because it can easily handle the loss or theft of keys. FIG. 5 shows the usage status of the data input device in the conventional system for unlocking with a card key. A device 3 called a door gate including a lock and its control circuit is attached to the door 1, and the door gate 3 is provided with a slot 5 for inserting a card key. When a card key is inserted into this slot 5, the data of the card key is stored in the key reader / writer (key R /
It is read by W) and collated with a room number and a gate ID number (hereinafter collectively referred to as an ID number) preset in the control circuit in the door gate 3. And
If the verification results match, the lock is unlocked.

Now, the data input machine 7 is a work for setting the ID number and other necessary data in advance in the control circuit in the door gate 3 (hereinafter referred to as initialization work).
Used in. The procedure of this initialization work is as shown in the flowchart of FIG.

First, a master card 9 which is permitted to be used only by a specific person on the hotel side is prepared (S1), and then FIG.
As shown in, the data input device 7 is connected to the data input device connector of the door gate 3 (S2, S3), and the master card 9 is inserted into the slot 5 of the door gate 3 (S4). Then, the data of the master card 9 (referred to as card data) is read into the door gate 3 and transferred to the data input device 7 via the door gate 3. This card data includes a card type such as a master card or a guest card, and a personal identification code known only to those who are permitted to use the master card 9.

The data input device 7 first checks the card type from the transferred card data (S6), and if it is a master card, then the secret code entered by the operator from the keypad of the data input device 7. Receive the code (S
8) Then, the personal identification code is compared with the personal identification code of the card data (S9). If they match, the ID number and various initial values are input to the data input device 7 (S13, S
14) is permitted, and the input value is transferred from the data input device 7 to the door gate 3 and registered in the control circuit in the gate (S15).

[0006]

One problem of the initialization work in this conventional system is that the data of the master card 9 is recognized by the card gate 3 and the data input device 7. Initialization work is done on this door
It is one of the most important tasks in ensuring the security of a lock system and should not be misused by anyone without working rights. For that purpose, it is necessary to prevent the security information on the master card 9 from being stolen. In that respect, it is possible that the security information is recognized by the device outside the card 9 such as the card gate 3 and the data input device 7 as in the conventional case.
This creates the possibility of accessing this security information and is not desirable.

Furthermore, another problem in the conventional initialization work is that the key R / W of the door gate 3 is used.
Since this key R / W is usually used frequently every day, it cannot be said that there is almost no failure. In the conventional initialization work, it is necessary to insert the master card into this key R / W, so if the key R / W fails, the initialization work cannot be performed until it is recovered, There is a problem that special measures must be taken to ensure the security of the.

Accordingly, it is an object of the present invention to disable access to security information to enable use of a data entry machine for door gate initialization operations, and
It is to improve the security of the door lock system by enabling the initialization work even if the door gate key R / W fails.

[0009]

According to the present invention, in a data input device for setting initialization data in a door gate of a door lock system, a code input device for inputting a personal identification code and an IC key are inserted. And an IC key reader / writer, code transmitting means for transmitting the personal identification code input from the code input device to the IC key via the IC key reader / writer, and returning from the IC key when a correct personal identification code is input. Received a normal response,
There is provided a data input device having a permission unit that permits setting of the initialization data to the door gate.

[0010]

When the door gate is initialized, the IC key is inserted into the data input device, the data input device is connected to the door gate, and the personal identification code is input from the code input means. The input secret code is sent from the data input device to the IC key, and the secret code is collated in the IC key. If the result of verification is a correct PIN code, I
A normal response is returned from the C key to the data input device.
In response to this normal response, the data input device allows the initialization data to be set in the door gate.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the appearance of one embodiment of a data input device according to the present invention.

The data input device 11 shown in FIG. 1 has a keypad 13 for inputting a number, a message display 15 and a connector 17 for connecting a door gate, like the conventional data input device 7 shown in FIG. It has a slot 19 for inserting an IC key (key on which an IC 23 including a microcomputer is mounted) 21.

In the data input device 11, an IC key reader / writer (IC key R / W) and a control circuit are provided. The IC key R / W is connected to the IC 23 on the IC key 21 inserted in the slot 19 to
It has a function of reading data from the IC 23 and inputting data to the IC 23. The control circuit includes an IC key R / W, a keypad 13, a display 15 and a connector 1.
7 to read data of the IC key 21 via the IC key R / W, send data input from the keypad 13 to the IC key 21 via the IC key R / w, A message is displayed on the display 15 and data read from the IC key 21 is input to the connector 17
It has the function of sending it to the door gate through.

The data input device 11 can be used not only for initialization work of a door gate of a type unlocked by a card key as shown in FIG. 5, but also for a door gate of a type unlocked by an IC key.

FIG. 6 shows the procedure for initializing the door gate using the data input device 11.

First, an IC key dedicated to data input (hereinafter referred to as a master key) is created using a key issuing machine installed at a hotel front desk or the like (S21).
The IC on the master key has a key type such as whether or not the key is a master key, a secret code known only to a specific person who has an initialization work right, data such as a room number to be set to a door gate and a gate ID (hereinafter, Setting data), and automatic operation data for causing the control circuit in the data input device 11 to automatically perform the data setting process for the door gate.

Next, the connector 17 of the data input device 11 is connected to the door gate connector (S22), the power of the data input device 11 is turned on, and the door pad initialization mode is selected by the keypad 13 (S23).

Next, the master key is inserted into the slot 19 of the data input device 11 (S (24)). Then, in the data input device 11, the key type data among the above-mentioned data stored in the master key is read into the control circuit via the key R / W (S25). The control circuit checks the key type (S26), and outputs an error display on the display 15 if the key is not the master key (S26).
27) In the case of the master key, a message prompting the user to enter the personal identification code is displayed on the display. After that, the operator inputs the personal identification code from the keypad 13 (S28).
Then, the control circuit transmits the inputted personal identification code to the master key via the key R / W (S29).

Next, the IC of the master key compares the personal identification code input from the data input device 11 with the pre-stored personal identification code to check whether the input personal identification code is correct (S30). ), If not correct, return an error response to the data input device 11 (S
32), in response thereto, the control circuit of the data input device 11 causes the display unit 15 to display a processing end message and the processing ends (S33). On the other hand, if the entered personal identification code is correct, the master key IC returns a normal response to the data input device 11 (S34).

When the normal response is received, the control circuit of the data input device 11 reads the automatic operation data and the setting data from the IC of the master key via the key R / W (S35). Then, the control circuit, according to the read automatic operation data,
The read setting data is transmitted to the door gate via the connector 17 and the registration process is automatically performed in the door gate (S36). When this setting process is completed, the control circuit displays a process end message on the display unit 15 to complete the process (S37).

In the above process, the password collation process for ensuring security is carried out in the IC of the master key, and the preset password does not go out of the master key. Therefore, there is no fear that the personal identification number is stolen, and the security is high.

Furthermore, if the information defining the operation permitted for each worker is also written in the IC of the master card, the work can be performed even when the usage right of the data input device 11 is released to the beneficiary. It is safe because the functions that can be used by each person are limited. Furthermore, for the purpose of education for those who do not operate it, it is convenient to prepare a PIN code for trial operation so that it can be utilized for such purposes without compromising security.

FIG. 3 shows another embodiment of the data input device according to the present invention.

This embodiment differs from the embodiment of FIG. 1 in that
An IC key type terminal 33 having the same shape as the IC key and an electric interface is used as a connection terminal with the door gate. The data input device 31 is exclusively used for a door gate of a type that unlocks with an IC key.

The procedure for initializing the door gate using the data input device 31 is that the IC key type terminal 33 is inserted into the IC key R / W of the door gate as a method for connecting the data input device 31 to the door gate. Except for this, the procedure is the same as that already described with reference to FIG.

The advantage of this data input device 31 is that it is not necessary to provide a special connector for connecting the data input device to the door gate, and the IC key type terminal 33 of the data input device 31 is connected to the slot 19 of the data input device 31. The data input device 31 can be self-tested.

FIG. 4 shows an example of a system configuration including the data input device 31 and the IC key issuing device of FIG.

The IC key issuing machine 41 is, for example, a computer installed at the front of a hotel, and is combined with a stationary IC key R / W 43.
Software for issuing an IC key via the key R / W 43 in a form that can be used at a facility in the hotel is incorporated.

The data input device 31 can communicate with the IC key issuing device 41 by inserting the IC key type terminal 33 into the IC key R / W 43 of the IC key issuing device 41.
By using this communication function, the following convenient usage is possible.

(1) The history of initializing the door gate using the data input device 31 is left in the data input device 31, and the history is transferred to the IC key issuing device 41 to issue the IC key. This is useful for checking whether or not the machine 41 has been properly initialized, grasping the current status of all door gates, and preventing erroneous IC key issuance that does not match the current status. In addition, IC key issuing machine 4
From 1 to the data input device 31, it is possible to place security-related restrictions on various operations that can be performed using the data input device 41.

(2) I using the IC key issuing machine 41
I used by other system when issuing C key
The C key is inserted into the data input device 31, only the necessary data is read by the data input device 31, and the IC key type terminal 33 of the data input device 31 is placed in the stationary type key R /
By inserting into W43, necessary information can be processed without changing the hardware and software on the issuing machine 41 side. For example, I used as a maid key in a hotel
While inserting the C key into the data input device 31, the personal identification number is input from the keypad of the data input device 31, and if the input personal identification number matches the personal identification number in the maid key, the personal identification number is temporarily stored in the maid key. When a master file is created and the IC key type terminal 33 of the data input device 31 is inserted into the stationary key R / W 43 in this state, the IC key issuing device 41 can treat the maid key as a master key. However, when the issuing operation ends, the master file is automatically erased, and the IC key inserted in the data input device 31 returns to the original maid key.

(3) When the data input device 31 is used for the first time, the data input device 31 itself is initialized (for example,
You have to write the code data according to the hotel. In this case, the building code unique to the hotel is sent from the IC key issuing machine 41 side to the data input machine 31 for initialization. At this time, if the software of the IC key issuing machine 41 is abused and the building code of another hotel can be set, the data input machine 31 may be abused in another hotel. Therefore, when the data input device 31 is initialized, an IC key valid for the hotel is inserted in the data input device 31 so that the building code issued by the IC key issuing device 41 and the building code of the IC key are the same. If you set it so that it cannot be initialized unless you do it, you can prevent the above abuse.

The preferred embodiments of the present invention have been described above, but the advantages of these embodiments are as described above.

(1) Since the identification code is collated in the IC key inserted in the data input device and the identification code does not appear on the line outside the IC key, it is almost impossible to access the identification code. High safety.

(2) It is not necessary to incorporate the software for checking the right of use of the data input device into the data input device or the door gate.

(3) Since the initial value can be automatically set in accordance with the automatic operation data programmed in the IC key, the operator's manual input is eliminated.
Further, since this automatic operation data is written in the IC key, it is highly safe. Furthermore, if a different master key is prepared for each different operation, by using the master key properly, various operations can be performed without knowing the detailed usage of the data input device.

(4) By writing the setting history in the memory of the IC key, the incorrect setting can be confirmed through the IC key even if the data input device does not have the memory.

(5) Even if the IC key R / W on the door gate side fails, the right of use of the data input device can be checked and processing can be performed. Also, by importing the data of the door gate failure status from the door gate to the data input machine side,
It is possible to understand the failure status.

[0039]

As described above, according to the present invention,
Verification of the PIN code to allow the use of the data input device is I
It is performed in the microcomputer on the C key, and security data such as a personal identification code does not appear on the external line, so the security is high. Furthermore, since the initial work can be performed even if the key R / W of the door gate fails, the security of the door lock system can be improved.
