Description

The present invention relates to an elevator and a control method thereof.

When the hall call button on each floor is pressed, the elevator operates to dispatch a car to that floor, but for security reasons, there are some halls where the car is not dispatched even if the hall call button is pressed. There are call-separation services and services that permit the dispatch of cars by performing cryptographic operations. Also, a service is being considered that allows building managers to remotely set up hall calls to be disconnected using communication lines.

In Patent Document 1, such a service is referred to as service floor disconnection (service floor disconnection operation), and even when the service floor is disconnected, a special message is sent to the platform call input device provided at the platform on the N floor, for example. When the operation is performed, the car is moved to the Nth floor, and if a user who boarded the car from the N floor specifies the entrance floor as the destination floor, the car is moved to the entrance floor and the user is offloaded. Then, when this user gets into the car and operates a door close button, etc., the car is moved to the N floor and the user is taken off (see summary). In other words, the service floor disconnection operation of Patent Document 1 is provided with means for canceling the service floor disconnection for a certain period of time during the service floor disconnection, so that even when the elevator is performing the service floor disconnection operation, the user on the N floor went down to the entrance floor so that he could run a short errand.

Japanese Patent Application Publication No. 2007-223690

In Patent Document 1, sufficient consideration is not given to the case where an elevator hall call is remotely disconnected by using a communication line. In a system that remotely disconnects elevator hall calls by using a communication line, the building manager cannot grasp the usage status of the elevator when remotely disconnecting elevator hall calls. For this reason, there is a possibility that a user may be left behind at the hall when the hall call is disconnected.

The present invention relates to an elevator, and more particularly to means for avoiding leaving a user stranded in a hall when a hall call is set to be separated. Examples thereof will be specifically described below with reference to the drawings. In each figure, the same components are given the same reference numerals and repeated explanations will be omitted. In the following description, the up-down direction corresponds to the up-and-down direction of the car.

With reference to FIG. 1, the configuration of elevator device 100 will be described. FIG. 1 is a schematic diagram showing a cross section of an elevator 100 according to an embodiment of the present invention, viewed from the side (horizontal direction).

The elevator 100 includes a car 104 and a counterweight 105 that move up and down in a hoistway 101, a hoist 103 around which a main rope (not shown) is wound, a car guide rail 106 that guides the car 104 up and down, and a counterweight. A counterweight guide rail 108 for guiding the weight 105 up and down is provided. A car door 104a for passengers to get on and off is provided on the entrance/exit side of the car 104 (on the landing hall 101b side).

The car 104 and the counterweight 105 are suspended by a main rope (not shown) inside a hoistway 101 provided in a building. The car guide rail 106 and the counterweight guide rail 108 are vertically provided along the inner wall 101a of the hoistway 101.

The elevator 100 of this embodiment is a traction type elevator device, in which a hoist 103 frictionally drives a main rope to move a car 104 up and down along a car guide rail 106, and a counterweight 105. It is moved up and down along the counterweight guide rail 108.

The hoistway 101 is formed in a building and is an elevating space in which a car 104 and a counterweight 105 move up and down. A control panel (control device) 102 that controls the operation of the elevator 100, including the raising and lowering of the car 104, is arranged within the hoistway 101.

In this embodiment, the hoisting machine 103 is arranged at the top of the hoistway 101, but the position of the hoisting machine 103 is not limited to the top of the hoistway 101. Further, a machine room may be provided in which the hoist 103 and the control panel 102 are placed. Although three halls (boarding halls) 101b are illustrated in FIG. 1, the number of halls is not limited to three, and more than two or three halls 101b may be provided. However, the effect of this embodiment becomes noticeable in an elevator used in a building in which a large number of halls 101b are provided.

In this embodiment, the elevator 100 is a traction type elevator, but the present embodiment is also applicable to elevators other than traction type elevators, for example, to hydraulic elevators.

The configuration of the device of this example will be explained using FIG. 2. FIG. 2 is a schematic diagram showing the configuration of equipment of the elevator 100 according to an embodiment of the present invention.

The external setting section 13 is configured, for example, as a dedicated web page, and by accessing and operating this dedicated web page from a terminal that the customer (building owner) operates, he or she can determine whether or not a landing call can be registered for each floor. Can be set. The setting contents are sent via the Internet 14 to a dedicated external server (not shown) in the communication center 12, and further sent from the dedicated external server to the communication control unit 6 via the communication line network 15, and a hall call disconnection setting record is sent. It is recorded in section 10.

The elevator user operates the hall call button 3 to call the elevator. A signal from the hall call button 3 is notified to the elevator operation control section 5 via the elevator I/F circuit 4. The elevator operation control section 5 checks with the hall call separation control section 9 whether or not the call can be registered. The hall call separation control unit 9 informs the elevator operation control unit 5 of whether or not the hall call can be registered, which is recorded in the hall call separation setting recording unit 10. If the hall call registration is possible, the elevator operation control unit 5 104 is dispatched to the floor of the hall call button 3 operated by the user center.

If the hall call registration is not possible, if a specific operation is performed, for example, if the hall call button 3 is pressed multiple times within a certain period of time, the hall leftover detection unit 8 detects the hall leftout. When the left-hole detection unit 8 detects the left-hole hole, it notifies the control center 11 of the left-hole hole via the communication control unit 6 and the communication line network 15. At the same time, the hall left-behind detection unit 8 dispatches the car 104 to the hall left-behind detection floor via the elevator operation control unit 5.

After receiving the notification, the control center 11 communicates with the user via the communication line network 15 and the communication control unit 6 using the in-car communication device 2 controlled by the voice communication unit 7.

Next, the overall processing for rescuing a hole left behind in this embodiment will be described using FIGS. 3A and 3B. FIG. 3A is a flowchart illustrating rescue processing for a stranded user according to an embodiment of the present invention. FIG. 3B is a flow (continuation of FIG. 3A) representing rescue processing for a stranded user according to an embodiment of the present invention.

For the hall call button 3 pressed in S201 and S202, the hall call disconnection control unit 9 and the hall call disconnection setting recording unit 10 determine whether the hall call disconnection setting has been performed via the elevator operation control unit 5. conduct. If the hall call is not an invalid floor due to hall call separation, the process ends.

In the case of the hall call invalid floor, in S203, the hall leftover detection unit 8 determines whether a specific operation has been performed, for example, whether the hall call button 3 has been pressed repeatedly within a certain period of time. If a user is left behind in the hall (landing) 101b (see Figure 1), the user may press the hall call button 3 many times in an attempt to call the elevator 1. In the example, the specific operation is an operation of repeatedly pressing the hall call button 3 within a certain period of time. In this case, the hall call button 3 for performing a specific operation constitutes a specific operation section. If the hall call button 3 is not pressed repeatedly, the process ends.

When the hall call button 3 is repeatedly pressed, the hall leftover detection unit 8 detects the hall leftovers (S204).

After receiving the control signal for the elevator 100 from the elevator operation control unit 5 in S205, the hall leftover detection unit 8 checks the usage status of the elevator 1, that is, the usage status of the car 104. If the car 104 is not in use for more than 3 minutes, the hall leftover detection unit 8 determines that the car 104 is in use and waits until the car 104 becomes unused (S206). .

When the car 104 is not in use, the left-in-hall detection unit 8 requests the elevator operation control unit 5 to dispatch the car 104, and the elevator operation control unit 5 allocates the car 104 to the floor where the left-in hall is detected. (S207).

The process waits for the user left behind to board the car 104 in S208.

If the elevator operation control unit 5 determines that the stranded user has entered the car 104 on the condition that the value of the load sensor increases by a certain amount, the elevator operation control unit 5 controls the car 104 in S209. Drive it to the ground floor. At this time, considering the possibility that the left-behind user is a suspicious person, while the car 104 is traveling from the floor where the left-behind hall was detected to the ground floor, the elevator operation control unit 5 does not respond to other calls. Control not to respond. This is to prevent the elevator user who made the call and the suspicious person from riding together in the case where the user left behind is a suspicious person.

In S210, the user left behind is dropped off, and the process ends. In this case, the elevator operation control unit 5 causes the car 104, which has been dispatched to the separation floor and carries the user who is left behind on the separation floor, to travel to the ground floor. Thereby, users who are left behind in the hall (hall) 109b when the hall call is disconnected can be rescued.

As explained above, the elevator 100 of this embodiment is
An elevator that performs separate operation for landing calls,
a specific operation unit 3 that performs a specific operation to notify that the user is left behind on the separation floor;
A hall left-behind detection unit 8 detects that a user is left behind on the separation floor in response to an operation of the specific operation unit 3,
When the hall left-behind detection unit 8 detects that a user is left behind on a separation floor, the elevator operation control unit 5 that controls the operation of the elevator 100 detects a car 104 on the separation floor where the user is left behind. request a ride.

Furthermore, the method for controlling the elevator 100 of this embodiment is as follows:
A control method for an elevator that performs a separate operation for landing calls, the method comprising:
a specific operation unit 3 that performs a specific operation to notify that the user is left behind on the separation floor;
A hall left-behind detection unit 8 detects that a user is left behind on the separation floor in response to an operation of the specific operation unit 3,
When the hall left-behind detection unit 8 detects that a user is left behind on a separated floor, the elevator operation control unit 5, which controls the operation of the elevator, dispatches the car to the separated floor where the user is left behind. request,
The elevator operation control unit 5 allocates the car 104 to the separated floor where the user is left behind.

Next, with reference to FIGS. 4A and 4B, the overall process for confirming the situation of a stranded user and rescuing the user will be described in order to ensure security. FIG. 4A is a flowchart showing a process for checking the situation of a stranded user and rescuing him, according to an embodiment of the present invention. FIG. 4B is a flow (continuation of FIG. 4A) representing a process for checking the situation of a stranded user and rescuing him, according to an embodiment of the present invention.

For the hall call button 3 pressed in S301 and S302, the hall call disconnection control unit 9 and the hall call disconnection setting recording unit 10 determine whether the hall call disconnection setting has been performed via the elevator operation control unit 5. conduct. If the hall call is not an invalid floor due to hall call separation, the process ends.

In the case of the hall call invalid floor, in S303, the hall leftover detection unit 8 determines whether a specific operation has been performed, for example, whether the hall call button 3 has been pressed repeatedly within a certain period of time. If the hall call button 3 is not pressed repeatedly, the process ends.

If the hall call button 3 is repeatedly pressed, the hall leftover detection unit 8 detects the hall leftovers (S304).

After receiving the control signal for the elevator 100 from the elevator operation control unit 5 in S305, the hall leftover detection unit 8 checks the usage status of the elevator 1, that is, the usage status of the car 104. If the car 104 has not been used for more than 3 minutes, the hall leftover detection unit 8 determines that the car 104 is in use and waits until the car 104 becomes unused (S306). .
When the elevator 1 is not in use, the left-in-hall detection unit 8 requests the elevator operation control unit 5 to allocate the car 104, and the elevator operation control unit 5 allocates the car 104 to the floor where the left-in-the-hall car is detected ( S307).

When the car 104 arrives at the left-behind detection floor, the user left behind on the separation floor gets into the car 104 and calls the control center 11 using the communication control unit 6 (S308). In this case, it is preferable to make an announcement or display a message to the user who has boarded the car 104 to call the control center 11.

The voice communication unit 7 receives a response from the control center 11 (S309), and determines whether the left-behind user is a suspicious person (S310). In the case of a suspicious person, a report is made to the building owner or the police (S311). In this case, a communication control unit 6 is provided which notifies the control center that the user is left behind on the separation floor when it is detected that the user is left behind on the separation floor. The communication control unit 6 performs telephone communication with the control center 11 when the car 104 arrives at the separation floor where the user is left behind. Then, by making a response from the control center 11, it is determined whether the user left behind on the separation floor is a suspicious person.

If the person is not a suspicious person (regular elevator user), the control center 11 instructs the hall left-behind detection unit 8 to rescue the person (S315). Upon receiving the rescue instruction, the left-behind-the-hall detection unit 8 instructs the elevator operation control unit 5 to execute the rescue, and the elevator operation control unit 5 confirms that the left-behind user is in the car 104 (S312). ).

If the elevator operation control unit 5 determines that the stranded user has entered the car 104 on the condition that the value of the load sensor increases by a certain amount, the elevator operation control unit 5 moves the car 104 to the ground floor. It runs (S313), unloads the remaining usage, and ends the process (S314).

This makes it possible to rescue users who are left behind in the hall (hall) 109b when the hall is called off while ensuring security.

The function of executing the processes shown in FIGS. 3A to 4B is incorporated into the control device 102. For this purpose, the control device 102 has a control program and necessary data. The elevator operation control unit 5 performs normal operation control in the control device 102 other than the hall call separation operation. The hall leftover detection unit 8, the hall call disconnection control unit 9, the hall call disconnection setting recording unit 10, etc. are incorporated into the control device 102, and cooperate with the elevator operation control unit 5 to control the elevator operation during the hall call disconnection operation. conduct.

If hall call registration is not possible, if a specific operation is performed, for example, if hall call button 3 is pressed multiple times within a certain period of time,
According to this embodiment, users who are left behind in the hall due to the disconnection of hall calls can be quickly rescued. Additionally, separation of hall calls is often used for security purposes. By driving in consideration of the possibility that the stranded user is a suspicious person, the safety of other users can also be ensured.

Note that the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the embodiments described above explain the present invention in detail in an easy-to-understand manner, and the present invention is not necessarily limited to having all the configurations described. Further, it is possible to add, delete, or replace a part of the configuration of each embodiment with other configurations.
