[Problem that the invention seeks to solve]

As described above, an electronic door lock device using a microcomputer can be unlocked with a key or by keying in a password. In particular, if you use the method of keying in your PIN code, you won't have to worry about losing or misplacing your key, which is useful.

Therefore, in recent years, such electronic door lock devices are increasingly being used for hotel room doors and lockers at golf courses. For electronic door lock devices used in such places, the PIN code may be changed every day from a security perspective, and for this reason, it is possible to change the input PIN code that has been set. It has become. Conventional devices have been used for this purpose, for example, by preparing a separate key for resetting the PIN code, setting this key corresponding to each door in the reset key operation part of that door, and then pressing the key on the door lock device's keyboard. Some devices allow you to set a new PIN code by operating the . However, this device requires a personal identification code to be set individually, which requires a great deal of effort and time. Therefore, a configuration in which the user can set the password individually could be considered, but in this case, for security reasons, it would be necessary to have the user set the PIN code without having the user use the reset key. must be reset by the administrator in advance. Furthermore, since you can use the system by operating the keyboard to register and register a PIN code, if you forget this PIN code, you will not be able to unlock it, and if you accidentally change the settings and forget the PIN code. There are times when the door goes missing, and in such cases, the manager has to go to the site each time to unlock the door, find the key specifically for that door in the key ring, and unlock it, which is a hassle.

Therefore, the purpose of this invention is to enable an administrator to easily set a PIN code for each of a large number of doors, to allow the PIN code to be updated with minimal effort, and to allow the PIN code to be confirmed. The purpose of the present invention is to provide a door lock device that provides a

A control means that performs controls such as reading and outputting a PIN code corresponding to this unique information when a command is given, an interface that exchanges information with the outside, and a connector for connecting to an external device connected to this interface. If a password code for each door is set in the memory in advance, the password code corresponding to the door number is output to the door lock device main body along with a renewal command just by manually inputting the door number. Then, upon receiving this code, the door lock device body side sets this code as a new code. Therefore, the administrator goes around each door with this external operation terminal device, connects the external operation terminal device to the connector of that door, and attempts to set the unique code for that door to that door simply by manually operating the key. You can set a PIN code. In addition, if a key is input to read out the PIN code set on the door, the PIN code is read out from the door lock device itself and displayed on the display means of the external operating terminal device, allowing the PIN code to be immediately confirmed. Can be done. Therefore, even if you lose your PIN code, you can still deal with the problem.
The password code for each door can be easily updated by simply using the unique code key. In addition, using a host computer that generates a unique code for each door and a new pin code, the external operation terminal device is connected to this host computer via a connector to generate a unique code for each door generated by the host computer. You can input and memorize a new PIN code. Therefore, even if you need to renew your PIN code every day for security reasons,
This management can now be performed by a host computer, minimizing the administrator's effort.

Therefore, according to the present invention, the administrator can easily set a PIN code for each of a large number of doors, change the PIN code with minimal effort, and confirm the PIN code. It is possible to provide a door lock device that can easily cope with a case where a password code is lost.

7. It consists of a connector 28.

The connector 26 is for connecting to the door lock device main body 10 via a cable, and the connector 28 is for connecting to a host computer such as a personal computer, which will be described later.

The keyboard 21 is used to perform predetermined command operations and input data from this external operation terminal device 20, and is used to input commands and data from the external operation terminal device 20.
2 is for displaying this input information and the information sent.

The CPU 23 converts input from the keyboard 21 into data and performs predetermined control according to this input, and also performs predetermined control according to input information.

For example, writing to the memory 24 in accordance with input from the keyboard 21, reading and outputting, displaying input/output information on the display 22, and storing information received from the outside in the memory 24. It also includes a function to store the unique information corresponding to the door A and the corresponding password code in the memory 24 as a set when the unique information corresponding to the door A and the corresponding password are received together with the storage command. Further, when the unique information corresponding to the door and a password code setting command are given from the keyboard 21, the password code corresponding to the unique information is read from the memory 24 and outputted to the interface 25. The USART 27 is a communication control circuit for serially transmitting data to and from a personal computer, and is connectable to the personal computer 30 via a connector 28.

Data is transferred between the door lock device main body 10 and the external operation terminal device 20 by handshake. Handshaking is a system in which an external output signal (transmission confirmation) and an external input signal (reception confirmation) are exchanged in response to a data signal, thereby mutually confirming that data has been transferred reliably. Moreover, the CPU 1 of the door lock device main body 10
3 is normally set in the sleeve mode in order to suppress current consumption, and when giving a command to the door lock device main body 10 from the external operation terminal device 20, it is necessary to first give a request signal.

The personal computer 30 has a program for generating and managing unique information for each door and its password code, and can generate these all at once and send them to the external operation terminal device 20 for storage. Also, if you enter the unique information for each door (for example, the room number for a guest room) from the keyboard of the computer 30, the PIN code will be sent to the computer 30.
The code is displayed on the display section of the door, and the user can be informed of the PIN code for the door lock device main body 1° of the door that the customer is using while looking at the screen.

Next, the operation of this device having the above configuration will be explained.

For example, in a hotel, if the PIN codes for the doors of all guest rooms are to be changed every day, the room attendant will need to use the external operating terminal device 2.
0 to the personal computer 30, and connect it to the computer 30 using the connector 28, as shown in FIG. 3(b). Then, by operating this personal computer 3o, a new password code for each guest room is generated or input. The PIN code generated in this manner corresponds to unique information for each guest room. Then, the personal computer 30 transmits this information to the external operation terminal device 20. Is this information USAI? The information is provided to the CPU 23 via T 27, and the CPU 23 updates and stores this information in the memory 24. FIG. 4 is a flowchart showing data transmission and reception from the personal computer to the external operation terminal device 20.

After storing the PIN code in this way, go to each guest room with the external operation terminal device 20 and proceed to the
As shown in a), the connector 17 of the door lock device main body 10 of the guest room and the connector 26 of the external operation terminal device 20 are connected with a cable. Then, the unique information corresponding to the room (for example, room number, etc.) and password update command are inputted from the keyboard 2I of the external operation terminal device f20. As a result, the CPU 23 reads the PIN code corresponding to the unique information from the memory 24, and sends it to Ilo 25. with the update command. Connector 26°17, Ilo
16 to the CPU 13 of the door lock device main body 10. Upon receiving this information, the CPU 13 replaces the verification password stored in the memory 14 with the received password.

The communication between the external operation terminal device 20 and the door lock device main body 10 in the above is performed by handshaking, and a specific example of the operation is shown in the flowchart of FIG. The flow of the operation of the locking device main body 10 is specifically shown in the flowchart of FIG.

This completes the renewal of the PIN code for this guest room.

Once completed, the external operation terminal device 20 is removed from the door lock device main body 10. The password codes for other guest rooms are updated in the same way.

Once the password has been set in this way, the front desk will use the computer 30 to check the guest's guest room password at check-in and notify the customer of the password.

The guest locks the door and goes out, and when he returns, he operates the keyboard 15 of the door lock device main body 10 to input a password. Then, the CPU 13 of this door executes a program and compares this input PIN code with a preset PIN code, and if they match, gives an unlock command to the unlocking device 12 and activates it. The locking mechanism 11 is unlocked. This will cause the door to open.

However, sometimes people forget their PIN code, and in such cases they are unable to open the door. In this case, the customer either goes to the front desk or calls the front desk and asks the front desk to unlock the door. After confirming that you are the guest in the room, the staff member will give you the PIN code.

In this way, the password code for each room is stored in the external operation terminal device 20, the external operation terminal device 20 is connected to the door lock device main body 10, and the password code for that room is entered by operating the keyboard 21 of the external operation terminal device 2°. By reading the code and sending it to the door lock device body 10 to update the PIN code, it is possible to update the PIN code for each room with minimal effort, and it is possible to update the PIN code for a large number of rooms. This can be easily done on the administrator's side, making it easier to manage password codes. Note that in this device, when an external operation terminal device 20 is connected to the door lock device main body 10 and a read command is given using the keyboard 21 of the external operation terminal device 20, the CPU 13 of the door lock device main body 10 functions to read the settings from the memory 14. Read the current PIN code and press 110
It can be output via 1B. Then, this is connected to the connector 2B, l1025, in the external operation terminal device 20.
The CPU 23 receives the information via the CPU 23 and displays it on the display 22.

Therefore, even if the customer does not know the password, he or she can confirm the password code at any time, thereby allowing the customer to set the password freely. Further, it is also possible to set the memorized password of the external operation terminal device 20 to a code designated by the customer.
