A second non-contact module has a chip microcomputer, and based on various information manually inputted from the second non-contact module, when it is determined that it is possible to enter the room, it notifies the second non-contact module to that effect, and automatically The control unit that opens and closes the entrance door checks whether the unique recognition code of the footwear transferred via the control unit is registered, transmits the results to the second non-contact module, and also closes the entrance door based on a notification from the control unit. There is a center that files management data such as the unique recognition code of footwear that has passed through, the time of passage, and the number of people.

(Operation) At the entrance, a person attempting to enter a room where entry is controlled should change into shoes with a unique recognition code written in advance on the first non-contact module and place them on the designated position in front of the entrance. By standing on the shoe, information is transmitted and received between the first non-contact module inside the shoe and the second non-contact module embedded in the floor, and the shoe's unique recognition code and usage data are retrieved. Can be done. Therefore, the center checks whether or not this unique recognition code is registered, and if it is registered, the control unit further checks the usage data and determines permission to enter the room.If it is determined that entry is possible, the automatic entrance door is opened. The automatic entrance door opens and closes again after a certain period of time. In this way, various management data can be obtained by automatically checking whether the user has changed into the specified shoes and by filing usage data at the center.

Opening/closing control.

Next, the operation of this embodiment will be explained with reference to the sequence diagram shown in FIG.

First, a person who wants to enter the room 31 where entry is restricted changes into shoes 1, each of which has a unique ID written in the non-contact module 3 in advance. The automatic entrance door 32 remains closed. Next, when the person wearing the shoes 1 stands at the position of the footrest mark 33 in the room 3I, the non-contact module 3 on the other side receives the start signal 4-1 from the non-contact module 4 of the legal system and sends a start signal. It returns a start OK signal 4-2 to 4-1, and first confirms that their positional relationship is such that communication is possible. Once mutual communication is confirmed, the non-contact module 4 of the legal system stops the start signal 4-1 and issues an ID request signal 4-3 to request ID data unique to the shoes 1. On the other hand, the non-contact module 3 on the other side sends out the ID data stored in the nonvolatile memory 21 as an ID data signal 4-4. The legal non-contact module 4 that has received the ID data signal 4-4 sends the received ID data to the center 9 via the control unit 6, and the center 9 checks whether this data is a registered ID or not. The check is performed and the result is notified to the non-contact module 4 of the legal system via the control unit 6. If the ID data is registered data, the non-contact module 4 of the legal system transmits a usage data request signal 4-5, and requests the usage data of the shoes 1 stored in the non-volatile memory 21 of the non-contact module 3 on the other side. (records of usage history, available range, etc.).

The non-contact module 3 on the other side sends a usage data request signal 4-
5 is received, the usage data is read from the non-volatile memory 21 and the usage data signal 4 is sent to the non-contact module 4 of the law.
-6. The legal non-contact module 4 that has received the usage data signal 4-6 stores the shoes when the usable range included therein matches the usable range recorded in the RAM 29 of the legal non-contact module 4. Usage data write request signal 4- to update the usage history of 1
7 to the non-contact module 3 on the other side. The non-contact module 3 on the other side that received this signal uses the non-volatile memory 2
After rewriting the usage data in 1, write usage data O
Send the K signal 4-8 to the contactless module 4 of the example.

The legal non-contact module 4 that has received the use data write OK signal 4-8 notifies the control unit 6 that the person wearing the shoes 1 can enter the room using the use OK signal -9. Upon receiving this signal, the control unit 6 transmits a notification OK signal -1O to the non-contact module 4 according to the law. Subsequently, the control unit 6 sends a door open request signal 4 to the automatic door 32 at the entrance 11.
-11 is transmitted, and the entrance automatic door 32 opens in response.
Return K signal 4-12 and open. When the entrance automatic door 32 opens, the person wearing it 1 enters the room. After that, the control unit 6
outputs a shoe position check signal 4-13, and in response to this, the non-contact module 4 again transmits a start signal 4-1. This time, since there is no start OK signal 4-2 from the shoe 1, this fact is notified to the control section 6 by the no-shoe signal 4-14. The control unit 6 outputs a door close request signal 4-15 to the entrance automatic door 32 after a certain period of time after manually issuing the open OK signal 4-12, and the entrance automatic door 32 responds to this by issuing the close OK signal 4-1.
Return 16 and close. Subsequently, the control section 6 notifies the center 9 of the ID data and time of passing of the shoes through the line 8, and the center 9 returns a reception OK signal 4-17, thereby completing the series of operations. If the above procedure is not performed normally, the automatic entrance door 32 will not be opened or closed.

In the basic sequence of this embodiment described above, the automatic entrance door 32 is opened and closed for each person, but since the door is closed indirectly and after a fixed time period has elapsed, for example, the automatic door 32 is opened and closed for each person. If the start OK signal 4-2 is input from the second non-contact module 3 (during the period from the ILS position check signal 4-13 to the door close request signal 4-15), the entrance automatic door 32 is not closed. Perform 10 checks and write usage data. Then, the center 9 is notified of the total number of shoes 1 that have passed and the ID data of each shoe 1. Therefore, in this case, the second person can use the room even if it is outside the usage range, but since a record remains in the center 9, unauthorized entry can be easily detected.

In this embodiment, the start signal 4-1 from the non-contact module 4 is stopped during the period from the first OK signal 4-2 to the shoe position check signal 4-13, but conversely, during this period The existence of the shoe 1 can be confirmed by continuously outputting the start signal 4-1 and the corresponding start OK signal 4-2, so after receiving the open OK signal 4-12, It is also possible to close the automatic entrance door 32 after a certain period of time after confirming that the start OK sign 4-2 has been resolved and the person has left. Further, the ID data can also be checked by the control section 6 instead of the center 9.

In this embodiment, the non-contact module 3 is embedded in the heel 2 of the shoe 1, but it may be embedded anywhere in the sole of the shoe 1 instead of the heel 2. Further, the shoes 1 are an example of footwear, and it is obvious that other footwear such as sandals or slippers may also be used. Furthermore, it is also possible to manage exit from the room by installing something similar to the non-contact module 4 described above in the exit floor of the room. Furthermore, considering that the shoe ID data is separated one pair at a time, management in ID groups is ideal for applications where entry restrictions and management can be performed on a group-by-group basis.

〔Effect of the invention〕

As explained above, the present invention stores a unique recognition code and usage data on the bottom of the footwear necessary for entering a room where entry management is performed, and asks a person who wants to enter the room to wear the footwear and enter the room. By standing on the footrest mark on the front floor and automatically extracting various information from the footwear, it is extremely easy to check and enter the room without giving the person who wants to enter the room the feeling of being controlled. This has the effect that it is possible to judge whether or not the data is available, and at the same time, necessary management data can be filed.
