FIG. 4 is a diagram for explaining the positional relationship of the elevators in this embodiment.

The operation unit 13 of the terminal device 10 outputs an abnormal signal to the control unit 11 when operated by the operator. The control unit 11, which receives the abnormal signal from the operation unit 13, outputs the abnormal signal with the address added to the transmitting unit 12. Transmission unit 12 from the control unit 11 is input an abnormal signal, elevators
An abnormal signal is output to the receiver 22 of the controller 20. The receiving unit 22 that receives the abnormal signal from the transmitting unit 12 of the terminal device 10 outputs the abnormal signal to the control unit 21. When the control unit 21 inputs an abnormal signal from the reception unit 22 (S101), it determines whether the elevator car is stopped at a preset floor (first designated floor) (S102). As described above, the first designated floor is a floor with an entrance that is easily accessed by suspicious persons.

Elevator car 3 stopped on the first designated floor
If 0n does not exist, the elevator car 30n is in the range A shown in FIG. 4, that is, the first designated floor and the floors immediately above and below the first designated floor (here, the second designated floor). It is determined whether or not it is located in the range (S103). The elevator car 30n is 301 (descent) or 3 shown in FIG.
If the elevator car 30n is scheduled to be stopped at the first designated floor when it is in the range A such as 02 (during rising), it is determined (S104). When the elevator car 30n in the range of A is not scheduled to stop at the first designated floor, the elevator car 30n does not stop at the first designated floor and performs normal operation as it is (S105). A above
If the elevator car 30n in the range of No. 1 is scheduled to stop at the first designated floor, the elevator car 30n is shown in FIG.
As indicated by reference numeral 31, the vehicle is stopped at the first designated floor (S1
06).

In step 103 (S103), when the elevator is not in the range A, the process shown in FIG. 3 described later is performed.

When there is a stopped elevator car on the first designated floor, such as the elevator car 31, all the stopped elevator cars 30n on the first designated floor are brought to an emergency stop (S1
07). Then, thereafter, the operation from the operation panel inside the elevator car 30n stopped as the emergency stop state on the first designated floor is invalidated. Also, or off the lighting of an elevator car which has an emergency stop, such as announcements by voice, so notifying operation of the elevator is invalid elevator passengers.

When an emergency stop release signal is input from the monitoring center 40 via the transmission / reception unit 26 (S108), the control unit 21 releases the emergency stop state of all elevators and operates from the operation panel inside the elevator. Is enabled (S109).

Next, the second embodiment of the present invention will be described.
This will be described based on the operation flowcharts of the elevator control devices of FIGS. 1, 4 and 3.

Since the operations of the terminal device 10 and the monitoring center 40 are the same as those in the first embodiment, the description thereof will be omitted.

Upon receiving the abnormal signal from the transmitting unit 12 of the terminal device 10, the receiving unit 22 outputs the abnormal signal to the control unit 21. Control unit
21 receives the abnormal signal from the receiver 22 (S121), the first
It is determined whether the elevator car is moving toward the designated floor of (S122). As in the elevator car 32 shown in FIG. 4, when there is an elevator moving toward the first designated floor, the control unit 21 cancels the first designated floor that is the destination of the elevator car (S123). , 32 'of FIG. 4, the elevator car is stopped at the second designated floor immediately above the first designated floor (S124). Then, when the first designated floor is selected as the destination floor by the operation panel of the elevator during the stop at the second designated floor (S125), the selection of the first designated floor is invalidated (S126). Then, the elevator notifies the user by audibly announcing that the elevator will not stop at the first designated floor (S127). The control unit 21 receives an emergency stop release signal from the monitoring center 40 via the transmission / reception unit 26 (S12
8), cancel the emergency stop state of all elevators, and accept the operation from the operation panel inside the elevator (S129).

Incidentally, step 103 in the above-mentioned first embodiment.
In (S103), the process when the elevator car is not in the range A is step 121 (S121) in the process flow of FIG. 3 described above.
Then, the same processing as that shown in FIG. 3 is performed.

Next, the operation of preventing the suspicious person of the elevator emergency stop system in the first and second embodiments from entering the inside of the building will be described.

[0040] For example, in the entrance hall of the building, if you find a person who guards that are Tatsu哨is deemed suspicious person, immediately when brought close to that person, to deal with, such as performing the conventional throat cage questioning. However, if the suspicious person
If you're about to board or have boarded an elevator that's already stopped on that floor,
It is not preferable to chase into the elevator and get into the situation. Further, when the standing position is far from the elevator boarding / alighting position, there may be no time to approach the person. In such a situation, the guard operates the operation unit 13 of the terminal device 10 of the present system to send an abnormal signal to the elevator control device 20.

The elevator control device 20 performs the processing according to the flow shown in FIGS. 2 and 3 described above.

That is, the elevator stopped at the floor of the entrance hall (first designated floor) is stopped from moving up and down in response to a command from the control unit of the elevator controller 20, and the stopped state is continued. Then, inside the elevator, for example, it is announced that the relevant elevator will make an emergency stop for an emergency inspection. This will prevent suspicious persons attempting to board the elevator or have already boarded the elevator from moving to other floors using the elevator. Then, this also secures the time for interviewing the suspicious person.

As for the elevator car that is scheduled to be stopped on the entrance floor (first designated floor) by the elevator that is moving up and down, the elevator car is stopped on the entrance floor as scheduled, and there is an emergency stop there to continue the stopped state. Never used by. In addition, when the abnormal signal is issued, elevator cars that are not on the upper and lower floors of the entrance floor and that are not scheduled to stop on the entrance floor will not be boarded by suspicious persons, and will continue moving as planned.

If the elevator is not in the range A of FIG. 4 when the security officer operates the terminal device and outputs the abnormal signal, the elevator car not scheduled to stop on the first designated floor Operation continues as it is, and the first
Those scheduled to stop on the designated floor will be stopped on the second designated floor. The passenger in the elevator car knows that the announcement in the elevator caused some abnormality and the passenger could not get off at the first designated floor of the intended entrance floor. However, the stopped first
Since the designated floor of 2 is directly above or below the entrance floor, you can easily reach the destination floor by using stairs and so on, without causing any inconvenience.

[0045]

As is apparent from the above detailed description, according to the invention of claim 1, when a security person discovers a suspicious person trying to get into an elevator car, the suspicious person is operated by operating the terminal device. Because it is possible to put the elevator car in an emergency stop state without noticing
The guards can put the elevator into an emergency stop without hesitation. Further, since a suspicious person is not locked in the elevator car, the safety of passengers in the elevator can be improved. Also, by carrying a security terminal,
Even if a suspicious person gets into the elevator by force, it is possible to prevent the suspicious person from entering the inside of the building.

Further, according to the invention described in claim 2, when the elevator which is moving up and down is scheduled to stop at the first designated floor, the elevator is stopped at another designated floor so that a suspicious person and other passengers can be stopped. It is possible to prevent a suspicious person from using the elevator without being caught. Further, since the elevator cars other than the elevator cars that are stopped at the first designated floor or are moving to the first designated floor operate normally, convenience can be maintained.

When the elevator is stopped in an emergency
The passengers should be informed by a voice display .
This allows passengers to use the elevator efficiently without hesitation even in the emergency stop state.
