  If the authentication information Ma and the authentication information Mb match, the order of the time Ta and the time Tb on the time axis is correct, and the elapsed time is within the allowable range, the fact that Mr. R has left the room is recorded and saved. . In this record storage, Mr. R 1 is deleted from the room attendee list, and the person's name and room entry / exit time are saved separately as a room attendant record, whereby the room attendant record is updated and saved.

  Next, when Mr. R leaves from step A52, the transmission of the ID of Mr. R from step A52 is also interrupted. With this, the door control device 3 determines that Mr. R's 1 exit is completed, and locks the door 51. Instruct and lock is complete.

  FIG. 11 is an explanatory diagram for explaining the personal authentication operation when Mr. R 1 who tried to enter the room stands in step A52 but leaves without entering the room as it is.

  First, when Mr. R 1 stands at step A52, the ID of Mr. R 1 is transmitted to the door control device 3 via step A52, and this ID is collated with the occupant name list DB 50. As a result of this ID collation, the authentication information Ma of Mr. R is acquired and the time Ta is also stored. Since Mr. R is a room entry permitter, the door control device 3 transmits an unlock signal for the door 51 to unlock the door 51.

  However, since Mr. R leaves without entering the door 51, Mr. R does not stand at step B53, and the ID signal input standby time at step B53 times out. Since the door control device 3 does not receive an ID input from Mr. R, it is determined that Mr. R has not entered the room and transmits a signal for closing and locking the door 51, and the door 51 is locked. These events are recorded as log information.

  According to the fourth embodiment, by providing such an intelligent key system in a living room, a laboratory, or the like, it is always possible to know who has entered the room at what time and when it has left the room. As a result, entrance management can be performed in laboratories that use dangerous chemicals, computer rooms that are filled with gas when a fire occurs and digested, and laboratories that absorb radiation that strictly controls the entrance time.

  In particular, rescue can be given priority because it can be easily confirmed whether there is a person left in the room at the time of the accident.

<Fifth embodiment>
In the fifth embodiment, in the configuration of the fourth embodiment, as shown in FIG. 12, a sensor 60 using laser light, infrared light, or the like is installed in the door 51, and the sensor 60 detects this. In this configuration, a signal is input to the door control device 3 through the sensor signal line 61.

  First, referring to FIG. 12 and FIG. 13, when Mr. R stands at step A <b> 52, the ID of Mr. R is transferred to the door control device 3 from step A <b> 52. The transferred ID is sent to the room occupant list DB 50, and the room occupant list DB 50 is searched based on the ID of Mr. R to perform ID verification. The authentication information Ma matching the ID is acquired, and the time Ta is also saved at the same time.

  Next, since it is confirmed by ID verification that Mr. R 1 is a room entry permitter, an unlocking signal is sent from the door control device 3 to the door 51 via the door unlocking signal line 56.

  When Mr. R 1 passes through the door 51, the sensor 60 detects the passage of Mr. R 1. The time Tdooa at the time of detection is stored.

  Next, when Mr. R 1 passes through the opened door 51 and stands at Step B53, the ID of Mr. R 1 is again transmitted from Step B53 to the door control device 3 via the Step B signal line 55, and ID Authentication information Mb and time Tb are acquired as a result of the collation.

  Then, it is confirmed that the authentication information Ma and the authentication information Mb match, and that the time Ta, the time Tdooa, and the time Tb are within the normal order and allowable time, and that it is recorded that Mr. R has entered the room. The This entry record is stored in the entry list in the entry list DB 50 until Mr. R 1 leaves, and the person name and entry / exit time are also saved as the entry record.

  Next, when Mr. R 1 leaves from step B53, transmission of the ID from step B53 is also stopped. Upon receiving the ID transmission stop, the door control device 3 determines that the room has been entered, closes the door 51, instructs locking, and is locked.

  For safety when closing the door 51, the sensor 60 can also be used to check whether there are any people or objects sandwiched between the doors 51, and further, a voice warning for closing the door 51, It can also be used as a safety measure by displaying guidance.

<Sixth Embodiment>
The sixth embodiment is a configuration example when the intelligent key system is implemented in public transportation such as a shared bus.

  FIG. 14 is a configuration diagram for explaining the configuration of the sixth embodiment. The configurations of the door control device 3 and the display 4 are the same as those of the first to fifth embodiments, except that a passenger list DB 65 for a shared bus is provided. Further, the door 66 controlled by the door control device 3, step A67 and step B68 provided with a human sensor and an electric field communication electrode, a door unlocking signal line 69, a step A signal line 70, and a pressure sensor (not shown). A pressure sensor A signal line 71 connected to A, a step B signal line 72, and a pressure sensor B signal line 73 connected to a pressure sensor B (not shown) are different.

  14, first, the authentication process shown in FIG. 15 for the case where Mr. R who has the RD terminal 2 for transmitting the ID registered in advance in the passenger list DB 65 of the door control device 3 provided in the shared bus gets on. This will be described with reference to FIG.

  As shown in FIG. 15, Mr. R, who is going to get on the shared bus, opens the shared bus door 66 by hand, and includes an electrode and a human sensor (pressure) sensor for electric field communication with the RD terminal 2. Stand in. When Mr. R stands at Step A67, the RD terminal 2 possessed by Mr. R1 passes from Step A67 to the door control device 3 via the Step A signal line 70 and the pressure sensor A signal line 71. The unique ID and the detection result of the pressure sensor A are sent.

  The door control device 3 compares this ID with the contents of the passenger list DB 65 registered in advance, acquires the authentication information Ma and time Ta of Mr. R, and stores it for a certain period. At this time, it is confirmed that Mr. R 1 is a passenger of a shared bus registered.

  Next, Mr. R stands at step B68. When Mr. R 1 stands in Step B68, Mr. R 1's possession of Mr. R 1 to the door control device 3 from Step B68 through the Step B signal line 72 and the pressure sensor B signal line 73 from the RD terminal 2 possessed by Mr. R ID and pressure sensor B detection result are sent. The door control device 3 compares the ID with the contents of the passenger list DB 65 registered in advance, acquires the authentication information Mb and time Tb of Mr. R, and stores them for a certain period. Here again, it is confirmed that Mr. R 1 is a passenger on a shared bus.

  Next, the door control device 3 compares the signals from Step A67 and Step B68, the authentication information Ma and the authentication information Mb match, and the time Ta and the time Tb are also appropriately within the allowable range on the time axis. It is confirmed that it is a long time, information from the same person, etc., and who has boarded at what time is saved. In this storage, Mr. R recognizes that the boarding of the shared bus has been completed, and updates and holds the boarding table in which the passengers currently on board are recorded.

  In the case of getting off, contrary to the case of getting on, it is detected by moving from step B68 to step A67.

  FIG. 16 is an explanatory diagram for explaining the authentication process when Mr. R 1 has the RD terminal 2 and tries to board another shared bus that is not registered in advance.

  First, Mr. R who tried to board another shared bus for which Mr. R 1 is not registered in advance opens the door of this shared bus by hand and stands in step A67 equipped with electrodes for electric field communication. When Mr. R stands at Step A67, the RD terminal 2 possessed by Mr. R1 passes from Step A67 to the door control device 3 via the Step A signal line 70 and the pressure sensor A signal line 71. The unique ID and the detection result of the pressure sensor A are sent.

  The door control device 3 compares this ID with the passenger list registered in the passenger list DB 65 in advance, but the ID of Mr. R is not registered. For this reason, the door control device 3 warns that the boarding bus of the boarding bus is △ No. △ bound for XX, please check the car number.

  Then, as shown in FIG. 17, when Mr. R who receives the warning gets off without going up to Step B68, only the fact that the event has occurred is stored for a certain period.

  On the other hand, when Mr. R goes up to Step B68 ignoring the warning, the processing shown in FIG. 18 is executed. When Mr. R 1 stands at Step B68, the Mr. R 1's RD terminal 2 possesses Mr. R from the Step B68 to the door control device 3 via the Step B signal line 72 and the pressure sensor B signal line 73. A unique ID and a detection result of the pressure sensor B are sent.

  Since the ID of Mr. R 1 is not registered in the door control device 3, the door control device 3 warns again that "the shared bus for boarding is the △ car bound for XX, please check the car number". When Mr. R who has received the warning gets off, only the fact that the event has occurred is stored for a certain period of time.

  In addition, when Mr. R 1 does not get off, the display 4 displays that there are passengers who have boarded an error and informs the crew on the bus.

  FIG. 19 is an explanatory diagram for explaining the flow of processing when Mr. R tries to get on the shared bus without having the RD terminal 2.

  First, even if Mr. R goes up to step A67, he does not have the RD terminal 2, so the ID is not transmitted and only the detection result of the pressure sensor is transmitted to the door control device 3 via the pressure sensor A signal line 71. The When only the signal of the pressure sensor A signal line 71 is input, the door control device 3 determines that a person who does not have the RD terminal 2 is about to get on.

  If Mr. R 1 who tries to get on is detected by the pressure sensor A but does not have the RD terminal 2 and therefore cannot obtain the correct ID, it is a complete mistake such as forgetting the RD terminal 2, Alternatively, an intentional ride by another person can be considered. In this case, the door control device 3 warns that the boarding bus of the boarding bus is △ bound for XX, the customer is not registered.

  As shown in FIG. 20, when the person who has received this warning cannot get the detection result of the pressure sensor B and gets off without going up to step B68, only the fact that the event has occurred is recorded for a certain period of time. To do.

  On the other hand, as shown in FIG. 21, when the person who has received this warning passes through step B68 from the detection result of the pressure sensor B, the situation is stored in the door control device 3 and at the same time the display 4 is erroneously boarded. To inform the crew on the bus. This information is stored until deleted by a previously authorized crew member.

  In the above description, it is assumed that the door 66 of the shared bus can be opened by hand or left open, but further security can be improved by incorporating the electric field communication electrode and the door control device 3 in the door 66 as well. .

  According to such a sixth embodiment, by providing an intelligent key system in a shared bus, when the shared bus temporarily stops and departs at a sightseeing spot or a highway relay point, Confirmation can always be done in real time. Conventionally, it is no longer necessary to confirm the passenger boarding situation that has been carried out by a crew member by visual inspection or call, and it is possible to prevent the number of passengers from being miscounted or from being overlooked.
