DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. FIG. 1 is a configuration diagram showing the inside of an office building.
In the figure, an office building 1 is, for example, a four-story building, the first floor is a lobby, and the second to fourth floors are tenants sharing an elevator landing door and an entrance door. In addition, the elevator car 3 suspended by the rope 2
Go up and down the fourth floor.

Each of the tenants on the first to fourth floors is provided with an intrusion sensor (not shown) that operates when an intrusion occurs.

FIG. 2 is a configuration diagram showing the inside of the elevator car 3 of FIG. In the figure, an indicator 5 is installed at, for example, an upper part of the car door 4 and the indicator 5
Are provided with car position indicator lights 51 on the first to fourth floors for displaying the position of the elevator car 3 and security lights 52 to 54 for indicating that the second to fourth floors are being guarded.

In the elevator car 3, an emergency call button 6 for reporting an emergency occurrence, a car call button 7 for the first to fourth floors for registering a car call to a desired floor, and a car door 4
A door opening / closing button 8 for opening / closing the door is provided.

Further, in the elevator car 3, a card (not shown) operated by a person who finally leaves the tenant on each floor is read to set the security start of the tenant corresponding to the floor number of the card, or set to each tenant. A card reader 9 is provided as an ID discriminating device that sets a security end by a card operation by a person who first enters the room and is in security when there is no person in each tenant, and monitors whether an intruder enters during security.

As shown in FIG. 3, the card reader 9 includes a reader head 91, a CPU 92, and a ROM 93.
, A RAM 94, an interface 95 for inputting and outputting signals, and a bus 96 to which the read head 91 to the interface 95 are connected. The passing position of the elevator car 3 output from an elevator control panel (not shown) When the elevator car 3 stops on the floor where the tenant being guarded is stopped, the security is ended based on the car position signal a and the elevator stop signal b when the elevator car 3 stops.

Further, the card reader 9 turns on the guard lights 52 to 54 of the guarded tenant, and outputs the car call registration prohibition signals c _{2 to} c ₄ of the guarded tenant to the elevator control panel. To prohibit car call registration of tenants who are guarding.

When the intrusion sensor in the tenant under security operates or when the landing button of the tenant under security is depressed, the card reader 9 sends the intrusion signals i _{2 to} i ₄ to the elevator control panel. Is output to notify the occurrence of intrusion.

The hall calls from the hall call buttons 102 to 104 are also output to the elevator control panel.

The CPU 92, ROM 83 and RA
The configuration with M94 sets the start and end of security of the corresponding tenant based on the ID collation, and during the security of the relevant tenant, prohibits the elevator control panel from registering the car call of the relevant tenant. When the landing button of the tenant is pressed or when the intrusion sensor in the corresponding tenant operates, the control means of the present invention is notified that the intrusion has occurred.

Next, the operation of the CPU 92 of the first embodiment configured as described above will be described with reference to the flowcharts of FIGS. Here, for example, when the tenant on the second floor exits the N-th floor by the last exiting person, and then the first-time tenant enters the room.

First, in step S1, it is determined whether or not the second floor is being guarded. If there is no person in the tenant on the second floor and security is in progress, the process proceeds to step S2.

[0020] In step S2, S3, the second floor of the car call registration inhibit signal c ₂ is not outputted to the elevator control panel, that this for the second floor of the car call registration go freedom to the second floor because it is possible it can.

Subsequently, in step S4, it is determined whether or not the card has been operated and the card has been read by the last exit of the tenants on the second to fourth floors. If there are still people, that is, if the card of each tenant has not been operated by the last person on the second to fourth floors, the process returns to step S1 and repeats steps S1 to S4 until the card is read.

In this state, the card is operated by a person who finally leaves the tenant on any of the second to fourth floors,
When the card is read in step S4, step S
Go to 5.

In step S5, if the collation result of the ID number of the read card is not OK, the process returns to step S1, and if the collation result of the ID number is OK, the I
When the D number is, for example, the number of the second floor, the process proceeds to step S6, in which the intrusion monitoring of the second floor intrusion sensor is set, and the second floor is guarded. Next, the process proceeds to step S7 via step S1.

In step S7 shown in FIG. 5, the security light 52 on the second floor is turned on.

Subsequently, in steps S8 and S9, 2
The car call registration inhibition signal c ₂ floors to prohibit the second floor of the car call registration is output to the elevator control panel. This allows
You cannot use the elevator to go to the second floor.

Subsequently, in step S10, it is determined whether or not the intrusion sensor installed in the tenant on the second floor has operated. If an intruder has entered the tenant on the second floor and the intrusion sensor has operated, step S11 is performed. Proceed to.

[0027] In step S11, S12, and outputs the second floor entry signal _{i 2} to notify the caretaker. This makes it possible to respond to intruders.

If the intrusion sensor in the tenant on the second floor does not operate in step S10, the process proceeds to step S13. Then, in step S13,
It is determined whether or not the hall call button 102 on the second floor has been pressed. If the button has been pressed, it means that an intruder has entered the tenant on the second floor and the intruder intends to use the elevator. Therefore, as in the case of the intrusion sensor in this case is operated, the process proceeds to step S11, S12, to notify the administrator by outputting an intrusion signal i _2.

In step S13, if the hall call button on the second floor is not pressed, there is no intruder in the tenant on the second floor, so the process proceeds to step S14 shown in FIG.

In step S14 of FIG. 6, it is determined whether or not the card has been read. If not, the flow returns to step S1. In this case, since the second floor is being guarded, steps S1 to S14 are repeated to keep the tenant on the second floor guarded.

In such a security state, in the above step S14, when the tenant on the second floor gets into the elevator car 3 and reads the card, that is, 2
Step S1 when entering the first occupant of the tenant on the floor
Go to 5.

If it is determined in step S15 that the collation result of the ID number of the read card is not OK, the process returns to step S1. On the other hand, the collation result of the ID number is OK, and the ID number is, for example, a second floor number. in this case, the process proceeds to step S16, the second floor stops the output of the car call registration inhibition signal c ₂ of, to blink upstairs patrol lamp 52 to notice the second floor of the security exit.

Subsequently, in step S17, when the first occupant of the tenant on the second floor registers a car call on the second floor, the elevator car 3 moves and stops at the second floor. This is detected based on the car position signal a and the elevator stop signal b.

After the elevator car 3 stops on the second floor, the security on the second floor is terminated in step S18, and step S18 is performed.
19. At S20, turn off the security light 52 on the second floor,
The intrusion monitoring by the intrusion sensor on the second floor ends.

Thereafter, the process returns to step S1 and repeats steps S1 to S20 described above.

The above operation has been described for the second floor with N = 2, but the same applies to the third and fourth floors. 3
On the 4th and 4th floors, security lights 53 and 5
4 is respectively registered to the elevator control panel inhibit signal c ₃ and c ₄ are output while being turned. When an intrusion occurs during security on the third and fourth floors, the intrusion signal i
₃ and _{i 4} are output.

Further, in the first embodiment, a response to the landing button 102 of the tenant is always enabled regardless of whether security is on. That is, when the landing button 102 of the tenant being guarded is pressed, the action is performed by the intruder, so that it is possible to detect that the intruder has entered, and in the event of a fire or the like, the intruder can go outside. This is to allow them to escape.

In the first embodiment, as described above,
Set the start and end of security of the tenant corresponding to the ID number of the card that was read, and during the security of the relevant tenant, prohibit the elevator control panel from registering the car call of the relevant tenant, and set the landing button of the relevant tenant. Is pressed or when the intrusion sensor in the corresponding tenant is operated, the intrusion is reported. Therefore, when the tenant is unmanned, the intruder can be detected while in security.

The present invention can be implemented according to the following embodiments. 1) While the car call registration inhibition signal c ₂ to c ₄ are called during i.e. car not output to the elevator control panel registration is permitted, notifies the display or sound that the in the elevator car 3.

2) The guarding lights 52 to 54 may be shared with passing lights indicating the passing floor of the elevator car 3. Also, the guarding lights 52 to 54 may be shared with the car position indicating light 51. Further, the guarding light may be shared with a car call indicator light for displaying the floor registered at the time of car call registration. In addition, when sharing, it distinguishes by changing brightness etc.

Embodiment 2 FIG. In the first embodiment, the card reader is installed in the elevator car. However, the present invention can be similarly implemented when installed in the elevator hall on the first floor.

Embodiment 3 FIG. In the first embodiment, the security light 5
