12 is connected to the ultrasonic detection unit 40, and the ultrasonic detection unit 40 detects a change in the moving object in the room and transfers a signal to be output to the reader / writer 112. The electric lock locks or unlocks the door electrically (electric cylinder lock, electromagnet, or the like) according to a command from the control unit of the reader / writer 112.

The personal computer 13 controls locking and unlocking of the doors, and monitors locking and unlocking of each door in real time. Further, the personal computer 13 manages a door key number and an ID number for which access is prohibited (hereinafter also referred to as an inaccessible ID number) stored in each door control unit. For example, the door key number of each room door is changed and confirmed, the inaccessible ID number is written to the memory 113 for each door control unit 11 of each room, read from the memory, or deleted from the memory. Perform control. Reader / writer 1
An alarm operation or the like is performed based on a signal sent from the ultrasonic sensing unit via the control unit 12. As the alarm operation, for example, a surveillance camera installed in a room is operated, or a warning is issued by sound.

Next, the operation of the first embodiment of the present invention will be described. First, a procedure of door access in the present embodiment will be described. FIG. 4 is a flowchart for explaining a door access procedure in the present embodiment. When the power of the door control unit is turned on, this flow is executed. In step S1, the green LED 115a is turned on to lock the electric lock. In step S2, it is detected whether the IC card is held over the antenna 110a or the antenna 110b. If the IC card has not been held, the process proceeds to step S3 to determine whether the push button 114 has been pressed. If the push button has not been pressed, the process shifts to step S4 to determine whether or not there is an instruction from the personal computer. If there is no instruction from the personal computer, the process returns to step S2 to detect the IC card again.

When an IC card is detected in step S2, the process proceeds to step S5, where the customer number, ID number and door key number of the detected IC card are read.
First, it is determined whether or not the read customer number matches the customer number stored in the memory. If they do not match, the process proceeds to step S11, where a first electronic sound indicating that the held IC card is not compatible with the system is emitted by an electronic buzzer for a predetermined time, and then returns to step S2. On the other hand, if it is determined in step S5 that the read customer number matches the customer number stored in the memory, the process shifts to step S6, where the IC card (ID
Card) is determined. If the touched IC card is an IC card to which a door key number is not written, that is, if it is not an ID card, step S
The process proceeds to step S11, where the electronic buzzer emits a first electronic sound indicating that the held IC card is not compatible with the system for a predetermined time, and then returns to step S2. If the held IC card is an ID card, step S7
Then, it is determined whether the read ID number is an inaccessible ID number stored in the memory. When the read ID number is the inaccessible ID number stored in the memory, the process proceeds to step S11,
For a certain period of time, a first electronic sound indicating that the held IC card is not compatible with the present system is emitted by an electronic buzzer, and the process returns to step S2.

If the ID number read in step S7 is not an inaccessible ID number, the process proceeds to step S8 to perform locking or unlocking. At this point, since the door is locked in step S1, the door is unlocked. Step S
At 9, the LED is turned on. At this point, the red LED is turned on because the lock is unlocked. When locking, green LE
D is turned on. In step S10, a second electronic sound is emitted when the electronic buzzer is normally locked or unlocked for a certain period of time, and the process returns to step S2. Hereinafter, by repeating the above steps, I
Detects D card and locks if door is unlocked,
Unlock if locked.

If it is determined in step S3 that the push button has been pressed, the flow shifts to step S8 to perform the above-described processing from step S8 to step S10. If there is an instruction from the personal computer in step S4, the process proceeds to step S12 to perform locking or unlocking according to the instruction.
Then, the green LED is turned on when locking is performed and the red LED is turned on when unlocked. In step S14, a third electronic sound indicating that the door has been unlocked or locked is issued in response to an instruction from the personal computer for a predetermined time, and then the process returns to step S2. Note that the electronic sound in this case may be the second electronic sound. The above-described flow of FIG. 4 ends when the power of the door control unit is turned off.

In a conventional system, an inaccessible ID
Stores all the codes in a database, determines whether the ID code read from the IC card held over the antenna matches the ID code stored in the database, and locks or unlocks the door. I was On the other hand, according to the present embodiment, it is sufficient to store the inaccessible ID number, so that the memory capacity is smaller than that of the conventional system, and an accessible ID number with a large storage amount is used. By judging whether or not the ID number is inaccessible with a small storage amount rather than judging whether or not there is, it is possible to judge the IC card much more quickly than in the conventional system, Therefore, locking and unlocking can be performed more quickly than in the conventional system.

Next, a procedure for changing or confirming the door key number of each door will be described. FIG.
5 is a flowchart for explaining a change of a door key number of each door. The flowchart shown in FIG.
Since there are some points in common with the flowchart for explaining the procedure for confirming the door key number, the procedure for confirming the door key number will also be described with reference to the flowchart in FIG.

The power of the door control unit is turned on in advance. When the screen shown in FIG. 6 is displayed on the display device of the personal computer, the flow shown in FIG. 5 can be executed. In step S20, the door key number (0 to 255) in the area on the right side of the screen in FIG. 6 is selected, and the door number of the door to be changed is selected. FIG. 6 shows a state where the door 1 is selected. In step S21, the door key number newly set in the input area below the write button is set to 0 to
Enter up to 255 numbers. Finally, when the write button is clicked (step S22), a command is sent from the personal computer to the door control unit of the door 1, and the door key number stored in the memory of the door control unit of the door 1 is changed to the newly set door key number. Is changed to Thus, the procedure for changing the door key number of the door control unit ends.

When confirming the door key number, after the procedure of step S20 shown in FIG. 5, the procedure of step S21 is skipped, and the read button is clicked in step S22. Then, the personal computer reads out the door key numbers stored in the memory of the door control unit of each door, and displays the read out door key numbers for doors 1 to 8 in the left area of the screen shown in FIG. In the screen of FIG. 6, a message "unlocked" or "locked" is displayed, and the read door key number of each door is displayed in this display area. Thus, the procedure for confirming the door key number is completed. To clear the display, click the display clear button at the lower left of the screen.
Clicking the Exit button returns to the initial screen (not shown). Note that the door key number is not limited to 0 to 255, and can be appropriately changed according to the number of doors of a hotel as a customer.

Next, the procedure of writing, reading, and deleting the inaccessible ID number to / from the memory will be described.
In a hotel, when a customer loses an IC card, it is necessary to immediately prohibit access to the room by the IC card. In such a case, the ID number of the inaccessible ID card is written to the memory of the door. FIG.
9 is a flowchart for explaining writing of an inaccessible ID number to a memory. Since the flowchart of FIG. 7 has common points with the flowchart for explaining the procedure of reading and deleting the inaccessible ID number, the procedure of reading and deleting the inaccessible ID number will also be described with reference to the flowchart of FIG. I do.

The power of the door control unit is turned on in advance. When the screen shown in FIG. 6 is displayed on the display device of the personal computer, the flow shown in FIG. 7 can be started. In step S30, an inaccessible ID (0 to 65535) in the area on the right side of the screen in FIG. 6 is selected, and a door number of a door whose access by a lost ID card is to be prohibited is selected. In the case of FIG. 6, the door 1 is selected. In step S31, the ID number of the ID card whose access is to be prohibited is input to the input area below the write button. Step S
At 32, a write button is clicked. Accordingly, the personal computer sends a command to the door control unit of the door 1 and writes the ID number of the lost ID card into the memory as an inaccessible ID number.

When reading the inaccessible ID number, after step S30 shown in FIG. 7, the read button is clicked in step S32 without inputting the ID number in step S31. Thereby, as shown in FIG.
The ID number of the ID card whose access to the memory of the door 1 is prohibited is displayed at the right corner of the screen in FIG. FIG.
7 is a partially enlarged view of the screen of FIG. In FIG. 8, “00”
"150", "00200" and "00100" are door 1
Is stored in the memory as the inaccessible ID number. Thus, for each selected door, the inaccessible ID
The number can be read and displayed on the screen.

When a lost ID card is found, the ID number is deleted from inaccessible ID numbers. When deleting an inaccessible ID number, FIG.
In step S31 of the procedure shown in (1), the user inputs an ID number to be deleted, and in step S32, clicks an inaccessible ID release button. As a result, the ID number stored as inaccessible in the memory of the door control unit is deleted. When deleting the inaccessible ID number, once
After reading out the inaccessible ID number stored in the memory of the door and displaying it on the screen, the displayed ID is displayed.
You may make it delete by selecting a number. Thereby, when deleting the inaccessible ID number, the trouble of inputting the ID number can be omitted and the ID number can be simplified. Click the Exit button to access I
The process of writing, reading, and deleting the D card is completed.

Next, a procedure for changing the door key number of the IC card will be described. FIG. 9 is a flowchart for explaining the change of the door key number of the IC card. The power of the reader / writer 15 connected to the personal computer is turned on in advance. When the screen shown in FIG. 10 is displayed on the display device of the personal computer, the flow in FIG. 9 can be executed. In step S40, a newly set door key number (a number from 0 to 255) is input into the door key number input area on the screen shown in FIG. In step S41, a write button is clicked. Thereby, the personal computer determines via the reader / writer 15 whether the IC card held over the antenna 16 is a customer card or an ID card (step S42). If the held card is not a customer card or an ID card, the process proceeds to step S45, where an electronic sound is emitted from the electronic buzzer for a certain period of time, and the process proceeds to step S46. Step S42
If it is determined that the held IC card is a customer card or an ID card, the process proceeds to step S43, where the input door key number is written on the IC card held over the antenna 16, and the writing is normally performed. Then, an electronic sound is issued (step S44), and the process proceeds to step S46. In step S46, it is determined whether the end button on the screen in FIG. 10 has been clicked. If it is not clicked, the process returns to step S42, and thereafter, the antenna 16
An ID card in which a new door key number is written can be created only by holding a customer card or an ID card over the. When the end button is clicked on the screen in FIG. 10, this processing ends.

In the present embodiment, when a hotel guest loses his or her IC card, the door key number of the door is usually written in a new IC card (customer card) or an ID card for another door to thereby obtain a new one. The ID card for the door is issued, the ID number of the lost IC card is stored in the door control unit, and subsequent access by the lost ID card is prohibited. By the way, when the number of lost ID cards increases and the number of inaccessible ID numbers stored in the memory increases, it takes time to determine the ID number. In such a case, by changing the door key number of the door, it is possible to delete all of the inaccessible ID numbers that have increased, thereby enabling quick confirmation of the ID numbers. Therefore, according to the present embodiment, even if the number of doors to be managed increases like a hotel, locking and unlocking of doors can be quickly controlled with a small memory capacity.

In the conventional system, when an IC card is lost, the ID code of the lost IC card is found and deleted from a database storing a large number of ID codes, and the ID code of a new IC card is inputted. ,
Must be registered in the database. On the other hand, in the present embodiment, when the IC card is lost, the ID number of the lost IC card is input and stored in the memory of the corresponding door control unit, and the customer card or another door ID card is stored. Is simply held over the antenna 16, a new ID card for the door can be issued. Therefore, according to the present embodiment, it is possible to deal with the loss of the IC card easily and quickly as compared with the conventional system.

By the way, using only the ID number of the IC card,
It is also possible to control the locking and unlocking of the door. However, in the case of this method, at least the number of ID numbers corresponding to the number of IC cards possessed by the hotel is required. On the other hand, in the case of the present embodiment, a door key number of only the number of doors of the hotel is sufficient. Therefore, according to the present embodiment, locking and unlocking of the door can be controlled with a smaller number of digits. Also, it is possible that the hotel can rewrite the ID number, but if the ID number can be rewritten,
Duplicate with the ID number of other IC card,
It is not preferable because the C card cannot be identified. However, even if the door key number is rewritten on the hotel side, only the door that can be locked or unlocked changes, so that no major problem occurs. Inaccessible I
The D number, once written, does not change. On the other hand, in the case of the method of managing by ID number, when re-issuing in the event of loss, it is necessary to delete the lost ID number and store a new ID number in the memory. Therefore, by managing with the door key number as in the present embodiment, the management of the IC card in the hotel as the customer can be simplified as compared with the method of managing only with the ID number.

Next, a procedure for locking or unlocking the door by a personal computer will be described. The power of the door control unit is turned on in advance. When the screen shown in FIG. 6 is displayed on the display device of the personal computer, and the doors of all the rooms of the hotel are to be locked at one time, the all lock button is clicked. To unlock all at once, click the unlock all button. When locking or unlocking the doors of each room individually, the user clicks the lock button or unlock button of the desired door number. Note that when locking or unlocking, the LED of the corresponding door control unit is turned on, and an electronic sound is emitted. Further, whether each door is locked or unlocked is displayed on the screen of FIG. FIG. 6 shows that the doors 1 to 3 and the doors 5 to 8 are unlocked and the door 4 is locked. Although eight doors are displayed in the diagram shown in FIG. 6, the present invention is not limited to this number, and may be nine or more or seven or less.

Next, monitoring and control of each door by a personal computer will be described. Each time the door is locked or unlocked, the door control unit of each door stores the history of the door, that is, the time, the ID number, from inside or outside, and whether the door is locked or unlocked, in the memory. When each door is monitored by the personal computer, the screen shown in FIG. 6 is displayed on the display device of the personal computer, and the door monitoring start button is clicked. As a result, the personal computer reads the history stored in the memory of each door control unit and displays the result on the screen as shown in FIG. In the screen shown in FIG.
At second, the door 3 is unlocked from the inside by the ID card with the ID number “00005”. As described above, in this embodiment, since the history of the door access is stored, which door is the ID card of which ID number,
Whether the antenna is unlocked or locked and the antenna at the time of access can be easily managed outside or indoor. Further, according to the present embodiment, the access status of the IC card to each door can be monitored in real time. It should be noted that although not shown in FIG. 11, the door control unit stores the information of the unusable IC card even when the information is read. Further, the past history may be viewed on this screen by scrolling as necessary.

Next, an ultrasonic sensing system will be described. In the present embodiment, when the ID card is held over the outdoor antenna and locked, the ultrasonic sensing system is activated. When a person enters the room while the ultrasonic sensing system is operating, the ultrasonic sensing unit 40 detects a moving object and sends a signal to the door control unit. Upon receiving this signal, the door control unit emits an alarm sound indicating an abnormality using the electronic buzzer.
This signal is sent to a personal computer,
The personal computer activates the surveillance camera installed in the room, automatically issues a warning by voice in the room, emits an alarm sound to notify the security room of the abnormality, and displays the abnormality on the display device. Or

According to the above-described embodiment, even in the case where the number of doors to be managed is large, such as a hotel, a conventional system that stores an accessible ID number and controls unlocking and locking of doors is provided. In comparison, since the number of ID numbers to be stored is much smaller, locking and unlocking of the door can be quickly controlled with a small memory capacity.

Further, when a plurality of IC cards are issued for one door, in the conventional case, a new I card is issued.
It is necessary to input and register all the ID numbers of the C card. On the other hand, in the case of the present embodiment, the user inputs the door key number, clicks the write button, and
By simply holding the D card over the antenna 16, any number of new ID cards can be issued easily and quickly without inputting the ID number of the IC card.

Further, according to the present embodiment, when the IC card is lost, a new door key number is stored in the IC card.
Create a C card and access its door control
Since it is possible to cope only by storing the D number, security management is also easy.

By the way, it is also possible to store the serial number of the IC card in the memory of the door control unit and manage the locking and unlocking of the door only by using the serial number. However, in the method of controlling the locking and unlocking of the door using only the serial number, it is necessary to store the accessible serial number in the memory of each door control unit. The serial number of a normal IC card has 4 bytes. Therefore, a memory having a larger capacity is required as compared with the present embodiment in which the door key number for one byte only needs to be stored in the memory. Also,
In the case of the present embodiment, the door key numbers of each IC card for unlocking or locking a door are all the same. On the other hand, if only the serial number is managed, each door control unit needs to store all serial numbers accessible to the door control unit. For example, in order to be able to use five IC cards for each door control unit, it is necessary to input and store five serial numbers for each door control unit of each door. . Since this serial number has 4 bytes, such an input operation becomes extremely complicated. On the other hand, according to the present embodiment, it is sufficient to store one door key number for each door control unit. Therefore, according to the present embodiment, the setting at the time of introducing the system is compared with the above method. It will be much easier.

In the above embodiment, the case where the outdoor side antenna and the indoor side antenna are provided for each door has been described. However, one antenna may be provided for each door. In this case, it is not possible to distinguish whether the IC card is held from indoors or from outside by merely holding the IC card over the antenna. However, since the switching unit can be omitted, the configuration is simplified.

[Second Embodiment] Next, a second embodiment of the present invention will be described.
