In the present embodiment, the personal recognition device 23A is, for example, a contactless card reader that reads an IC card with a built-in RFIC (Radio Frequency Integral Circuit) tag. When the user PX holds the IC card over the antenna unit (not shown) of the personal recognition device 23A, the personal recognition device 23A communicates with the RFIC tag built in the IC card and is stored in the RFIC tag in advance. The data is read, and it is checked whether it matches the ID data registered in advance, and personal recognition is performed.

  As shown in FIG. 1, an operation panel 17 is installed in each dwelling unit 8. The operation panel 17 remotely unlocks the entrance door or calls a visitor who calls from the entrance hall 7 with the interphone 26A. An operation panel 27 for setting the use permission of the elevator so as to be able to come to the dwelling unit 8 and inputting a room number in the apartment, and an intercom 26M are provided.

As shown in FIG. 1, an operation panel 13 is installed in the car 1. The operation panel 13 includes a destination floor button (destination setting means) 21a for inputting and setting a destination floor, and an elevator door (not shown). A door opening button (door opening means) 21b for opening the door, an operation panel 21 provided with a door closing button 21c for closing the door, and a personal recognition device (personal recognition means) 23B. Yes.
The personal recognition device 23B is also a device of the same type as the personal recognition device 23A. In this embodiment, for example, it is a contactless card reader that reads an IC card with a built-in RFIC tag.

The operation panel 13 is connected to a car control microcomputer (hereinafter referred to as car control MPU) 11 installed in the car 1, and the car control MPU 11 is connected to a car control MPU board 31, which will be described later, via the multiplex transmission line 4. Connected.
The car control MPU 11 performs lighting control of the destination floor button 21a on the operation panel 21, reception of destination floor input, position display control of the current car 1, control of the personal recognition device 23B, and the like. The car control MPU 11 performs door opening / closing control when the car 1 arrives at the destination floor.

In the elevator hall on each floor, hall buttons (hall calling means) HB1, HB2, HB3, HB4,..., HBN for calling the car 1 are provided. Here, in order to simplify the explanation, it is assumed that one elevator is installed in the elevator hall.
Hall buttons HB1 to HBN (arbitrary N) are hall control microcomputers (hall call means) (hereinafter referred to as hall control MPU) 6A, 6B, 6C, 6D,... Installed in the elevator halls on each floor. , 6N (arbitrary N described above). Hall control MPUs 6A to 6N perform lighting control of hall buttons HB1 to HBN and position display control of the car 1, and are provided in each elevator unit (one unit in this embodiment) to be described later via the multiplex transmission path 5. A car call signal is input to a machine control microcomputer board (hereinafter referred to as a machine control MPU board) 31 of the machine control panel 3.
In the present embodiment, the MPU board has a storage unit in addition to the microcomputer and the peripheral LSI (Large Scale Integration).

When a plurality of elevators are installed in one elevator hall, a group management MPU board 2 for group management of them is provided, and a car call signal is sent to the group management MPU board 2 as indicated by a broken line. It is input via the multiplex transmission path 5. Then, as shown by the broken line, the group management MPU board 2 is connected to the unit control MPU board 31 through a communication line to acquire the state of each unit, and the nearest car 1 or Then, the waiting car 1 in which no destination floor is set is made to arrive at the floor where the car is called.
The unit control MPU board 31 or the group management MPU board 2 has the above-described storage unit (not shown), and associates the ID data of each apartment resident with the destination floor permitting door opening in advance. I remember it.
The storage unit of the unit control MPU board 31 or the group management MPU board 2 is connected to, for example, a management computer of a condominium management office (not shown) via a communication line, and permits the ID data and door opening. The destination floor may be updated by the management computer.

  Incidentally, the door (not shown) of the car 1 is provided with a normally installed photoelectric door sensor, a multi-beam door sensor using infrared rays, and the like. When the car control MPU 11 starts the door closing operation, these sensors are provided. When the car detects an obstacle, the car control MPU 11 interrupts the door closing operation.

Next, referring to FIG. 2 to FIG. 4 (refer to FIG. 1 as appropriate), the destination floor is set from the setting of the destination floor when the visitor in this embodiment or the user PX who is a resident of this apartment gets on the car 1. The door opening / closing control of the car 1 after arriving at will be described.
FIG. 2 and FIG. 3 are flowcharts for explaining the flow of control of destination registration and door opening / closing operation until the user enters the destination floor and enters the destination floor, then arrives at the destination floor and opens and closes the door. . Here, the destination registration means that the car control MPU 11 communicates with the unit control MPU board 31 (or the group management MPU board 2) and accepts the setting operation to the permitted destination floor of the personally recognized user PX. This means that the destination floor is set in the unit control MPU board 31 (or the group management MPU board 2).
First, a case where the user PX is a resident of this apartment will be described.
The user PX holds the IC card for personal recognition issued in advance from the condominium management office over the antenna part of the personal recognition device 23A, and reads the ID data stored in the IC card. The personal recognition device 23A refers to data registered in advance in the storage unit of the unit control MPU board 31 or the group management MPU board 2 and checks whether the read ID data is included in the pre-registered data. To do. If it is included, it is determined that the apartment is a resident, and the entrance door (not shown) of the entrance hall 7 is unlocked and automatically opened by the door sensor. If the elevator car 1 is not located on the floor of the entrance hall 7, the car is called to arrive there.

When the data read by the personal recognition device 23A is not included in the registered data, the entrance door is not unlocked and the call to the floor of the entrance hall 7 of the car 1 is not made. In this case, the personal recognition device 23A may announce that “it was not recognized as a resident of this apartment”.
Hereinafter, the description will be made on the case where the user PX is a resident of an apartment.
The user PX enters the elevator hall and gets into the car 1 with the door open. If the door of the car 1 is not open, the user PX presses the hall button HB1 to open the door.
The operation of the destination floor button 21a to the floor of the entrance hall 7 can be registered without the personal recognition operation by the IC card. The unit control MPU board 31, the group management MPU board 2, and the car control MPU 11 are programmed. Suppose that

When the user PX gets on the car 1, he presses the destination floor button 21a on the operation panel 21 to input the destination floor, and holds the IC card over the antenna unit (not shown) of the personal recognition device 23B. The following control is mainly performed in the car control MPU 11.
In step S101, it is checked whether or not the destination floor button 21a has been pressed. If the destination floor button 21a is pressed (Yes), the process proceeds to step S102, and if not (No), step S101 is repeated.

In step S102, the car control MPU 11 communicates with the car unit control MPU board 31 or the group management MPU board 2 to check whether the destination floor has already been permitted. This step is a step when the user PX is a visitor and will be described later. In this case, since the destination floor is not yet permitted (No), the process proceeds to step S103.
Even if a predetermined number of seconds have elapsed after the destination floor button 21a is pressed, if the user PX has not yet performed the personal recognition operation and the input destination floor cannot be compared with the ID data, In step S103, an announcement “Please perform recognition operation” is made to prompt the user PX to perform the recognition operation.

In step S104, it is checked whether the recognition result matches the input destination floor. Specifically, the ID data read by the personal recognition device 23B is collated with data registered in advance in the storage unit of the unit control MPU board 31 or the group management MPU board 2, and the input destination floor is It is checked whether or not the ID data is permitted.
If they do not match (No), the process proceeds to step S105, invalidates the destination floor input, and returns to step S101. This case includes cases where the data cannot be read, the read data does not match that registered in the storage unit, or the destination floor is not allowed to be input to the ID data.
If they match (Yes), the process proceeds to step S106, and the car control MPU 11 communicates with the car unit control MPU board 31 to register the destination. That is, the car control MPU 11 sends a destination floor instruction to the number control MPU board 31 through the multiplex transmission line 4. The machine control MPU board 31 controls a car drive motor (not shown) and moves the car 1 to the designated destination floor (step S107).
In step S104, if there is no recognition operation within a predetermined time after the destination floor button 21a is pressed, the destination floor input may be invalidated and the process may return to step S101.

The car control MPU 11 communicates with the car unit control MPU board 31 and checks whether or not it has reached the floor registered in step S106 (step S108). If it arrives (Yes), the process proceeds to step S109, and if not, step S108 is repeated.
In step S109, the door is opened and the destination registration registered in step S106 is reset. Then, the timer t1 is started (step S110). Further, the door open button 21b is validated (step S111). Here, enabling the door open button 21b means that the door of the car 1 is closed by, for example, pressing the door close button 21c while the timer t1 is less than a predetermined time T1 set in advance. This means that the door can be opened again by pressing the open button 21b. Normally, while the timer t1 is less than the predetermined time T1, the door continues to open, and when the predetermined time T1 is reached, the door closing operation is started.
This predetermined time is set to be shorter, for example, 10 seconds or less, giving priority to security.

In step S112, it is checked whether or not the timer t1 is equal to or longer than a predetermined time T1. If the timer t1 is equal to or longer than the predetermined time T1 (Yes), the process proceeds to step S115. If the timer t1 is less than the predetermined time T1 (No), the process proceeds to step S113.
In step S113, it is checked whether or not the door open button 21b has been operated. If there is a push operation on the door open button 21b (Yes), the door is opened (step S114). At this time, if the door is already open, the door closing operation is prevented. Then, the process returns to step S112. When there is no push operation of the door open button 21b in step S113 (No), the process directly returns to step S112.

When the process proceeds from step S112 to step S115 (Yes), it is checked whether or not the operation of the door open button 21b is continued from an arbitrary time when the timer t1 is less than the predetermined time T1 to the present. When the operation of the door open button 21b is continued, for example, when there are a large number of people getting off or when it takes time to get off, or when the timer t1 last falls from a time point less than the predetermined time T1, or This is a case where a person who remains in the car 1 continues to push and operate the door opening button 21b. In that case (Yes), the door opening operation is continued (step S116), and the process returns to step S115. If a buzzer sound is emitted during this step S116, a security warning is given to the surrounding people, which is convenient for alerting.
When the push operation of the door open button 21b is not continued (No), the door open button 21b is invalidated (step S117). Thereafter, the door is closed (step S118). This means that even if the user PX presses the door open button 21b after this time, it is ignored. When the door is starting to close, the door closes even if the door open button 21b is pressed.

The door closing operation by pressing the door closing button 21c is omitted in the flowchart. However, even when the timer t1 is less than the predetermined time T1, the door closing operation is performed when the door closing button 21c is pressed. When the door is closed, the door open button 21b is invalidated.
As described above, a series of destination registration, door opening operation, and door closing operation control until the user enters the destination floor and inputs the destination floor and then arrives at the destination floor and opens the door is completed.

Next, referring to FIG. 4, when it arrives at the destination floor, it takes time to get out of the car, and when the door is closed, the door opening operation is controlled by the operation of the door opening button. The flow of will be described. FIG. 4 is a flowchart for explaining the control flow of the opening operation.
This control is also performed by the car control MPU 11.
In step S201, it is checked whether another destination floor is registered. This is because another user still remains in the car 1 and there is a destination floor that has already been entered and registered as a destination, or the hall button on the other floor is pressed and the MPU board 31 for controlling the machine Says when a command to move to that floor is issued. In that case (Yes), the processing ends as it is. That is, even if the door opening button 21b is pressed, it is ignored.
When that is not right (No), it is checked whether the door open button 21b was operated (step S202). If the door open button 21b is not operated (No), the process returns to step S201. When the door open button 21b is operated (Yes), an announcement “Please perform recognition operation” is made (step S203). Then, it waits for the personal recognition device 23B to read the ID data.

If the personal recognition device 23B reads the ID data, it is checked in step S204 whether the recognition result matches the current floor. Specifically, the ID data read by the personal recognition device 23B is collated with data registered in advance in the storage unit of the unit control MPU board 31 or the group management MPU board 2, and the current floor has its ID. Check if it is allowed for the data.
If the recognition result matches the current floor (Yes), the door is opened (step S205), and the process proceeds to step S110 in the flowchart of FIG. If the recognition result does not match the current floor (No), the door opening input is invalidated (step S206), that is, even if the door opening button 21b is pressed, it is ignored. Then, the process returns to step S201.
In step S204, if the recognition operation is not performed even after a predetermined time has passed since the door open button 21b is operated, the process proceeds to step S206.
Further, when the door opening input is invalidated in step S206, an announcement such as “You are not allowed to get down to this floor” may be made.

  Steps S104 and S106 in the flowchart in the present embodiment constitute destination registration means of the present invention, and steps S115 and S116 constitute door opening invalidation means.

  With the control described above with reference to FIGS. 2 to 4, an outside person passes through the entrance door together with the resident of this apartment, gets into the elevator car 1 and the resident gets off at his destination floor. When the timer t1 automatically reaches the predetermined time T1 and the door closes, and the resident who gets out of the car 1 moves away from the elevator hall, the person outside the car 1 presses the door open button 21b. If you try to open the door by operating it, it will not open. Since this person does not have an IC card, even if the destination floor button 21a other than the floor of the entrance hall 7 is pressed, it cannot be permitted by the personal recognition device 23B. Press the floor button 21a to get out of the apartment.

Next, the case where the user PX is an external visitor will be described.
The visitor enters the entrance hall, inputs the room number of the dwelling unit 8 to be visited from the operation panel 25, asks the resident PA to remotely unlock the front door using the operation panel 27, using the interphone 26A, and Get permission to the destination floor.

Hereinafter, the explanation will be made on the case where the user PX is a visitor to an apartment and does not have an IC card.
The user PX enters the elevator hall and gets into the car 1 with the door open. If the door of the car 1 is not open, the user PX presses the hall button HB1 to open the door.

FIG. 2 and FIG. 3 are flowcharts for explaining the flow of control of destination registration and door opening operation until the user enters the destination floor and enters the destination floor, then arrives at the destination floor and opens the door.
When the user PX gets on the car 1, he presses the destination floor button on the operation panel 21 and inputs the destination floor.
In step S101, it is checked whether or not the destination floor button 21a has been pressed. If the destination floor button 21a is pressed (Yes), the process proceeds to step S102, and if not (No), S101 is repeated.

In step S102, the car control MPU 11 communicates with the car unit control MPU board 31 or the group management MPU board 2 to check whether the destination floor has already been permitted. In this case, the car control MPU 11 communicates with the car unit control MPU board 31 or the group management MPU board 2 and confirms that the destination floor has already been permitted (Yes), so the process proceeds to step S106.
From step S106 to step S118, the control is the same as when the user PX is a resident, and a duplicate description is omitted.
If the visitor fails to get off the car 1 at the target floor, the operation of the door open button 21b of the control in FIG. 4 is ignored, so the resident PA who is scheduled to visit again at the entrance hall 7 will be informed of the destination floor. You will be asked for permission settings.

In order to make it possible for the visitor to recognize the individual, when the resident PA inputs the destination floor permission on the operation panel 27, a temporary password is set so that the individual in the car 1 is recognized. The device may be provided with a numeric keypad, and a visitor may register a destination floor by inputting a temporary password taught by an interphone from the numeric keypad instead of holding the IC card. When the registration of the destination floor is completed, the destination floor permission set by the resident PA is deleted from the unit control MPU board 31 or the group management MPU board 2.
By doing so, multiple elevators are installed in the elevator hall, and if the resident tries to go to the same floor as the visitor, the destination floor permission of the visitor is invalidated by the resident's destination floor button operation. Can be prevented.

According to this embodiment, even when the elevator car 1 having the security function arrives at the destination floor registered for the destination floor and closes once after the door opening operation, the personal recognition device 23B performs the recognition operation on the destination floor. Then, the door can be opened, which is convenient for the user PX who fails to get off.
Moreover, since the time for enabling the door opening button 21b can be set short, it is possible to suppress the intrusion of the suspicious person into the floor that is not permitted.
Also, giving a temporary password to the visitor ensures the permission of the visitor to the destination floor, which is convenient for the visitor.

In this embodiment, the RFIC reader as the personal recognition device 23A, 23B reads the data by the user PX holding the IC card over the antenna unit. However, the present invention is not limited to this. For example, within 30 cm within the front of the device. If the user PX stands up, the data of the RFIC tag possessed may be read.
Moreover, although the personal recognition devices 23A and 23B are RFIC tag readers in this embodiment, the present invention is not limited to this. It may be a fingerprint recognition device, a hand shape recognition device, a finger or hand vein pattern recognition device, a face recognition device, or a voice recognition device using a voiceprint.

  In addition, although this embodiment demonstrated the elevator for condominiums as an example, it is not limited to it. For example, if a common elevator is installed on the floor where only specially authorized employees can get off in office buildings and the floor where general employees can get off It can also be applied to restricting unnecessary entry to the floor where only employees can get off.
