Description

The present invention relates to an elevator control system and an elevator control method that perform rescue control operation when an abnormality occurs.

If a car door fails to close while the elevator is in operation, control is performed to stop the car from operating in order to ensure the safety of users. In this case, the car may be stopped at a position different from the floor position of the landing, resulting in a situation where the door of the car cannot be opened. Therefore, the users inside the car cannot get out of the car until the maintenance staff performs restoration work.

On the other hand, Patent Document 1 discloses that when a user is trapped in a car, the driving mode is set to manual mode by remote control from a monitoring center, and low-speed driving is possible inside the car until the user reaches a predetermined landing position. A technology has been disclosed to enable driving.

Japanese Patent Application Publication No. 1994-298462

However, failure to close the door of a car often occurs due to, for example, a string-like object being caught in the gap between the doors or coming into contact with equipment in the tower. Therefore, if low-speed operation is performed in the wrong direction, the doors and equipment inside the tower may be damaged, making it difficult for users to voluntarily exit the tower.

An object of one aspect of the present invention is to provide an elevator control system that can appropriately determine the direction of movement when performing rescue operation control to move the car to a predetermined landing floor after stopping the car when an abnormality is detected. do.

In order to solve the above problems, an elevator control system according to aspect 1 of the present invention includes an abnormality detection section that detects an abnormality regarding the operation of the elevator, and a movement control section that controls movement of a car, The movement control unit performs control to stop the movement of the car when the abnormality detection unit detects an abnormality, and (1) controls the movement of the car from the start of movement immediately before the abnormality detection to the stop when the abnormality is detected. (2) at least one of the following: the distance traveled by the car; and (2) the detection result of a door installed at the landing at the start of movement, in which the car was stopped at the start of movement immediately before the abnormality was detected, to be closed incorrectly. Based on one of the above, a moving direction is determined when carrying out rescue operation control to move the car to a predetermined landing floor after the car has stopped when the abnormality is detected.

According to the above configuration, the direction of movement of the rescue operation is determined based on the travel distance of the car from the start of movement to the stop immediately before the detection of an abnormality, so that the rescue operation can be performed in an appropriate direction of movement according to the distance traveled. becomes possible. In addition, as mentioned above, by determining the direction of movement of the rescue operation based on the detection result of a failure to close the door provided at the landing where the car was stopped at the time of the start of movement, the direction of movement of the rescue operation is determined. This makes it possible to carry out a rescue operation in an appropriate direction depending on the condition of the door.

In the elevator control system according to Aspect 2 of the present invention, in Aspect 1, the movement control unit (1) when the traveling distance is less than a predetermined value, moves in a direction opposite to the direction in which the movement was being performed by the time the abnormality was detected. (2) control for moving the car in the direction in which the car was moving in the direction in which it was moving before the abnormality was detected when the traveling distance is a predetermined value or more; and (2) at the time of starting the movement. If a closing failure of the door provided at the landing is detected, move the car in the opposite direction to the direction in which it was moving before the abnormality was detected, and If a closing failure of the door is not detected, at least one of the following may be performed: control to move the car in the direction in which it was moving before the abnormality was detected.

If the distance traveled is less than a predetermined value, or if it is detected that the door installed at the landing at the start of movement is not properly closed, an obstacle such as a string may be caught between the landing and the car at the start of movement. It is possible that this situation is occurring. In this case, by moving the car in the opposite direction to the direction in which it was moving before the abnormality was detected, the rescue operation can be performed without aggravating the abnormal situation.

Furthermore, if the travel distance is equal to or greater than a predetermined value, there is a possibility that the vehicle came into contact with specific tower equipment when passing near the tower equipment. In this case, by moving the car in the direction in which it was moving before the abnormality was detected, a rescue operation can be performed without contacting the tower equipment again.

The elevator control system according to aspect 3 of the present invention, in aspect 1 or 2 above, includes an operation detection section that receives an operation signal indicating an operation input by a user to an operation section provided in the car, and The movement control section may perform the rescue operation control during a period in which the operation detection section is receiving the operation signal indicating that the operation input is being performed.

According to the above configuration, the rescue operation will be performed during the period when the user is performing operation input, so the rescue operation will be performed only during the period when the user recognizes that there will be no problem even if the user moves by rescue operation. A rescue operation will be carried out. Therefore, it is possible to suppress the possibility that the user will end up in a dangerous situation due to the rescue operation.

In the elevator control system according to aspect 4 of the present invention, in the above aspect 3, the operation signal is such that at least one of a button instructing a door closing operation or an opening operation and a button instructing a destination floor is used. It may be a signal generated by being operated by a person.

According to the above configuration, operation signals used for controlling the rescue operation are generated by buttons provided on a normal elevator car, such as a button for instructing the closing or opening operation of the door and a button for instructing the destination floor. is generated. That is, the rescue operation control as described above can be realized without providing a special operation button for rescue operation control on the car, so that the introduction cost can be kept low.

The elevator control system according to aspect 5 of the present invention, in any one of aspects 1 to 4 above, includes a door control section that controls the opening/closing operation of the door of the car, and the door control section is configured to operate during the rescue operation. The door closing torque in the direction of closing the door may be larger than the door closing torque during normal operation.

According to the above configuration, the rescue operation can be performed with the door closed as much as possible during a period in which the user recognizes that there is no problem even if the user moves through the rescue operation. Therefore, for example, in a situation where the user's finger is caught in the door, a door closing torque is not applied, and a rescue operation can be performed after confirming the safety of the user.

The elevator control system according to aspect 6 of the present invention, in any one of aspects 1 to 5 above, provides for a user in the car during a period in which the rescue operation control by the movement control section is performed. The vehicle may further include an information presentation control unit that performs control to present at least one of the moving direction and the distance or time to the nearest floor when performing the rescue operation control.

According to the above configuration, since the user is notified of the direction of movement and the distance and time to the nearest floor during the rescue operation, it is possible to reduce the user's sense of anxiety during the rescue operation.

In order to solve the above problems, an elevator control method according to aspect 7 of the present invention includes an abnormality detection step of detecting an abnormality regarding the operation of the elevator, and a movement control step of controlling movement of the car, The movement control step performs control to stop the movement of the car when an abnormality is detected in the abnormality detection step, and (1) controls the movement of the car from the start of movement immediately before the abnormality detection to the stop when the abnormality is detected. (2) at least one of the following: the distance traveled by the car; and (2) the detection result of a door installed at the landing at the start of movement, in which the car was stopped at the start of movement immediately before the abnormality was detected, to be closed incorrectly. Based on one of the above, a moving direction is determined when carrying out rescue operation control to move the car to a predetermined landing floor after the car has stopped when the abnormality is detected.

According to the above configuration, the same effects as in the first embodiment can be achieved.

The elevator control system according to each aspect of the present invention may be realized by a computer, and in this case, the elevator control system can be implemented by the computer by operating the computer as each part (software element) included in the elevator control system. A control program for an elevator control system that is realized by the above control program and a computer-readable recording medium on which the program is recorded also fall within the scope of the present invention.

According to one aspect of the present invention, it is possible to appropriately determine the moving direction when performing rescue operation control for moving the car to a predetermined landing floor after the car has stopped when an abnormality is detected.

[Embodiment 1]
<Configuration of elevator control system 100>
Hereinafter, one embodiment of the present invention will be described in detail. FIG. 1 is a functional block diagram showing an example of the configuration of an elevator control system 100 according to the present embodiment. As shown in FIG. 1, the elevator control system 100 includes an elevator control device 1 and an elevator 2. The elevator control device 1 is a device that controls the operation of the elevator 2, and the elevator 2 operates the car 20 and the like under the control of the elevator control device 1. In addition, in the following description, the elevator control system 100 exemplifies a configuration that includes only one car 20 of the elevator 2, but the number of cars 20 of the elevator 2 is not limited to this, and a plurality of cars may exist. .

The elevator control system 100 performs normal operation control to move the car 20 based on hall calls and car calls when no abnormality occurs in the car 20 of the elevator 2, and when an abnormality regarding the operation of the elevator 2 occurs. This system performs rescue operation control that moves the car 20 to the nearest floor and allows the user riding in the car 20 to get off the car. An abnormality related to the operation of the elevator 2 is, for example, a door closing failure of the car 20 of the elevator 2. Door closing failure means that the door 24 opens while the car 20 is running due to a foreign object getting caught in the door 24 of the car 20, or the car 20 comes into contact with equipment in the tower, and then closes normally. It is now impossible to do so.

In the elevator control system 100, when an abnormality regarding the operation of the elevator 2 occurs, the elevator control device 1 detects the occurrence of the abnormality and performs rescue operation control. In the rescue operation control, the elevator control device 1 performs control to stop the movement of the car 20. Further, the elevator control device 1 determines the moving direction of the car 20 according to the position of the car 20 when the abnormality occurs, and performs control to move the car 20 at low speed in the determined direction. Furthermore, when the car 20 arrives at the nearest floor, the elevator control device 1 controls to open the door 24 of the car 20 and the hall door 28. Thereby, even if an abnormality regarding the operation of the elevator 2 occurs, the user can be safely alighted from the car 20.

Further, in the elevator control system 100, the elevator control device 1 determines whether or not the car 20 has stopped after the car 20 has stopped when the abnormality is detected, based on the traveling distance of the car 20 from the start of movement immediately before the abnormality was detected to the stop when the abnormality was detected. Determine the direction of movement when performing rescue operation control to move to a predetermined landing floor. As described above, the elevator control system 100 determines the direction of movement of the rescue operation based on the traveling distance of the car 20 from the start of movement to the stop immediately before an abnormality is detected, so that the rescue operation can be performed in an appropriate direction of movement. It becomes possible to do this.

In this embodiment, a configuration will be described in which the elevator control system 100 determines the movement direction of the rescue operation based on the traveling distance of the car 20, but this is the method for determining the movement direction of the rescue operation. Not limited to. For example, in the elevator control system 100, the abnormality is detected based on the detection result of a door closing failure of the landing door 28 provided at the landing at the start of the movement where the car 20 was stopped at the start of movement immediately before the abnormality was detected. The direction of movement may be determined when carrying out rescue operation control to move the car 20 to a predetermined landing floor after it has stopped.

[Elevator control device 1]
As shown in FIG. 1, the elevator control device 1 includes a control section 11, a communication section 12, and a storage section 13. The control unit 11 controls the elevator control device 1 to execute each process. Details of the control unit 11 will be described later. The communication unit 12 is an interface through which the elevator control device 1 exchanges information with each device of the elevator control system 100. The elevator control device 1 is connected to the elevator 2 and sends and receives various information via the communication section 12. The connection method between the elevator control device 1 and the elevator 2 may be a wireless connection or a wired connection. The storage unit 13 stores various computer programs read by the control unit 11 and data used in various processes executed by the control unit 11.

As shown in FIG. 1, the control unit 11 includes a reception unit 111, an abnormality detection unit 112, a door control unit 113, an information presentation control unit 114, a mileage specifying unit 115, an operation detection unit 116, and a movement control unit 117. .

The reception unit 111 receives hall calls and car calls. The reception unit 111 causes the storage unit 13 to store at least one of the moving direction and destination floor specified by the received hall call and car call. Note that while the elevator control device 1 is controlling the rescue operation, the reception unit 111 may stop accepting hall calls and car calls.

The abnormality detection unit 112 detects an abnormality regarding the operation of the elevator 2. Specifically, the abnormality detection unit 112 detects that the car door switch, which is the detection unit 27 of the car 20, has been switched. If the car door switch turns from on to off while the car 20 is moving between floors, the abnormality detection unit 112 determines that an abnormality has occurred in the operation of the car 20 of the elevator 2, and activates each part of the control unit 11. Information indicating that an abnormality related to the operation of the elevator 2 has been detected is output. As a result, rescue operation control is started in the elevator control device 1. Specifically, a situation in which the car door switch is turned off while the car 20 is moving between floors occurs when the door 24 is opened while the car 20 is moving.

The door control unit 113 controls the opening/closing operation of the door 24 of the car 20. During normal operation, when the car 20 arrives at any floor, the door control unit 113 transmits a signal to the car 20 instructing to open the door 24. Further, the door control unit 113 receives a signal from the car 20 of the elevator 2 indicating that an operation instructing to close the door 24 of the car 20 has been performed, or a predetermined period of time has elapsed since the door 24 was opened. Then, a signal instructing to close the door 24 is transmitted to the car 20.

When the door control unit 113 acquires information indicating that an abnormality related to the operation of the elevator 2 has been detected from the abnormality detection unit 112, the door control unit 113 performs control to close the door 24. Specifically, when an abnormality occurs in the operation of the elevator 2, the door control unit 113 transmits a signal to the car 20 instructing to close the door 24. Here, the door control unit 113 transmits a signal to the car 20 instructing to make the door closing torque in the direction of closing the door 24 during the rescue operation larger than the door closing torque during the normal operation.

Further, the door control unit 113 performs control to close the door 24 during a period in which the operation detection unit 116 receives an operation signal indicating that an operation input is being performed. Specifically, the period during which the operation detection section 116 is receiving the operation signal is the period during which the button on the operation section 26 of the car 20 is pressed. While the operation unit 26 is receiving the operation signal, the door control unit 113 acquires information from the operation detection unit 116 indicating that an operation input is being performed by the user. Thereby, the door control unit 113 can recognize the period during which the operation detection unit 116 is receiving an operation signal indicating that an operation input is being performed.

The door control unit 113 transmits a signal instructing to close the door 24 with the door closing torque increased to the control unit 22 of the elevator 2 only during the period when the operation detection unit 116 is receiving the operation signal. .

As a result, the elevator control device 1 can execute the rescue operation with the door 24 closed as much as possible during the period when the user recognizes that there is no problem even if the user moves using the rescue operation control. can. Therefore, for example, when the user's finger is caught in the door, the door closing torque is not applied, and rescue operation can be performed after confirming the user's safety.

The information presentation control section 114 transmits information to be notified to the user to the car 20, and controls the presentation section 25 to present the information. For example, when the abnormality detection unit 112 detects that an abnormality has occurred in the car 20, the information presentation control unit 114 sends a message to the presentation unit 25 indicating that an abnormality has occurred and the car 20 is to be stopped. have it presented. Note that the information presented to the user is not limited to the display of a message, and may be, for example, a blinking lamp, an audio output, or the like.

The information presentation control unit 114 also determines what action the user in the car 20 in which the abnormality has occurred should take next, such as trying to remove something stuck in the door 24 or pressing a specific button. It is also possible to display a message encouraging the user to take action. For example, after the car 20 has stopped, the information presentation control unit 114 displays a message prompting the user to press the operating unit 26 to instruct the driver to close the door. Furthermore, when the door closing failure is resolved, the information presentation control unit 114 displays a message prompting the user to press the operation unit 26 that can accept an operation for controlling the rescue operation.

Furthermore, the information presentation control unit 114 informs the users in the car 20 of the movement direction and the nearest location during the period when the rescue operation control is being performed by the movement control unit 117. Control is performed to present at least one of the distance and time to the floor. As a result, the user is notified of the direction of movement and the distance and time to the nearest floor during the rescue operation, so it is possible to reduce the user's anxiety during the rescue operation.

When the travel distance identification unit 115 acquires information indicating that the occurrence of an abnormality related to the operation of the elevator 2 is detected from the abnormality detection unit 112, the travel distance identification unit 115 determines the distance of the car 20 from the start of movement immediately before the abnormality detection to the stop at the time of the abnormality detection. Determine the distance traveled.

For example, the traveling distance specifying unit 115 identifies the traveling distance based on the elapsed time from the timing when the car 20 immediately started traveling to the timing when the abnormality was detected and the traveling speed of the car 20. The mileage specifying unit 115 outputs information indicating the identified mileage to the movement control unit 117.

The operation detection unit 116 receives an operation signal indicating a user's operation input to the operation unit 26 provided in the car 20. The operation signal is a signal generated when the user operates at least one of the button that instructs the door 24 to close or open, and the button that instructs the destination floor.

While receiving the operation signal, the operation detection section 116 outputs information indicating that the user is inputting an operation to each section of the control section 11 . This allows each part of the control unit 11 to recognize that the user is operating the operation unit 26.

The movement control unit 117 controls movement of the car 20. The movement control unit 117 performs normal operation control and rescue operation control. If the abnormality detection unit 112 does not detect an abnormality, the movement control unit 117 performs normal operation control. In normal operation control, the movement control unit 117 moves the car 20 based on the hall call and car call received by the reception unit 111, and opens and closes the door 24 of the car 20.

On the other hand, if information indicating that an abnormality regarding the operation of the elevator 2 has been detected is obtained from the abnormality detection unit 112, the movement control unit 117 ensures the safety of the users in the car 20 in which the abnormality has occurred. Perform control for Specifically, the movement control unit 117 performs control to stop the movement of the car 20 when the abnormality detection unit 112 detects an abnormality. When acquiring information indicating that an abnormality related to the operation of the elevator 2 has been detected from the abnormality detection unit 112, the movement control unit 117 issues an instruction to stop the movement of the car 20 via the communication unit 12. A signal is sent to the drive unit 23.

When the abnormality detection unit 112 detects an abnormality, for example, a door 24 is not closed properly in the car 20. In such a case, if the car 20 is moved to the scheduled floor as it is, the abnormality may become worse due to movement of the foreign object caught in the door 24, for example. Therefore, when an abnormality occurs, by temporarily stopping the movement of the car 20, it is possible to reduce the possibility that the situation will worsen.

After stopping the movement of the car 20, the movement control unit 117 acquires the detection result of the detection unit 27 of the car 20. When the detection result of the detection unit 27 indicates that the door 24 of the car 20 is closed, specifically, when the car door switch that is the detection unit 27 is turned on, the movement control unit 117 starts the rescue operation. Take control. The movement control unit 117 performs rescue operation control after the door 24 is closed, thereby reducing the possibility that the car 20 is moved with the door continuing to be improperly closed, thereby posing a danger to the users inside. be able to.

The movement control unit 117 may acquire the detection results of the detection unit 27 of the car 20 multiple times, for example, three times. As a result, even if the door closing failure has not been resolved at the first detection, rescue operation control can be performed if the door closing failure has been resolved at the second and subsequent detections. Note that if the movement control unit 117 acquires the detection results of the detection unit 27 of the car 20 a prescribed number of times and continues to acquire the detection results indicating that the door 24 is not closed, it does not perform rescue operation control. The car 20 is brought to a stopped state.

When the detection result of the detection unit 27 indicates that the door 24 of the car 20 is closed, the movement control unit 117 first obtains information indicating the distance traveled by the car 20 from the distance identification unit 115. . The movement control unit 117 performs a rescue operation that moves the car 20 to a predetermined landing floor after the car 20 stops when an abnormality is detected, based on the travel distance of the car 20 from the start of movement immediately before the abnormality is detected to the stop when the abnormality is detected. Determine the direction of movement when controlling the operation. As an example, if the traveling distance is less than a predetermined value, the movement control unit 117 determines the moving direction of the car 20 to be the opposite direction to the direction in which it was moving before the abnormality was detected, and the traveling distance is determined to be the predetermined value. In the above case, the moving direction of the car 20 is determined to be the direction in which it was moving before the abnormality was detected.

After determining the moving direction of the car 20, the movement control unit 117 transmits a signal to the car 20 instructing it to move in the determined direction. As a result, the movement control unit 117 moves the car 20 in the opposite direction to the direction in which it was moving until the abnormality was detected when the travel distance is less than a predetermined value, and when the travel distance is greater than or equal to the predetermined value. , performs control to move the car 20 in the direction in which it was moving before the abnormality was detected.

2 and 3 are schematic diagrams showing an example of a state when an abnormality related to operation occurs in the elevator 2. FIG. 2 shows the state of the car 20 when the travel distance of the car 20 from the start of movement immediately before the abnormality is detected to the stop when the abnormality is detected is less than a predetermined value, and FIG. 3 shows the state of the car 20 when the abnormality is detected. The state of the car 20 is shown when the travel distance of the car 20 from the previous start of movement to the stop when an abnormality is detected is equal to or greater than a predetermined value. Note that both FIGS. 2 and 3 illustrate a situation in which the car 20 moves upward from the first floor as a departure floor.

As shown in FIG. 2, if an abnormality is detected when the traveling distance of the car 20 (distance indicated by arrow Y1 in FIG. There is a possibility that an obstacle X1 such as the following may be caught. In this case, if the car 20 is moved in the direction in which it was moving before the abnormality was detected, the obstacle X1 will be pulled by the landing door 28 and the door 24 of the car 20, causing damage to the obstacle X1 or the door 24. Such abnormal situations may worsen. In addition, if the obstacle X1 is, for example, a pet lead, and the pet is left behind at the landing, if the car 20 is moved in the direction in which it was moving before the abnormality was detected, the car 20 will The leash may be pulled and your pet may be in danger. Here, if the traveling distance is less than a predetermined value, the movement control unit 117 performs control to move the car in the opposite direction to the direction in which it was moving until the abnormality was detected, thereby making the abnormal situation worse. It is possible to carry out a rescue operation without any problems.

In addition, if an abnormality is detected when the traveling distance of the car 20 (the distance indicated by the arrow Y2 in FIG. 3) is equal to or greater than a predetermined value, as shown in FIG. It is conceivable that the car 20 may have come into contact with the tower equipment X2. In this case, by moving the car in the direction in which it was moving before the abnormality was detected, the rescue operation can be performed without contacting the tower equipment X2 again.

Furthermore, the movement control unit 117 performs rescue operation control during a period in which the operation detection unit 116 receives an operation signal indicating that an operation input is being performed. Specifically, the period during which the operation detection section 116 is receiving the operation signal is the period during which the button on the operation section 26 of the car 20 is pressed. While the operation unit 26 is receiving the operation signal, the movement control unit 117 acquires from the operation detection unit 116 information indicating that an operation input is being performed by the user. Thereby, the movement control unit 117 can recognize the period during which the operation detection unit 116 is receiving an operation signal indicating that an operation input is being performed. The movement control unit 117 transmits a signal to the control unit 22 of the elevator 2 instructing to move the car 20 only during the period when the operation detection unit 116 is receiving the operation signal.

According to the above configuration, the rescue operation will be performed during the period when the user is performing operation input, so the period during which the user recognizes that there is no problem even if the user moves by rescue operation. A rescue operation will only be carried out. Therefore, the possibility of the car 20 being moved at an unintended timing by the user in the abnormality car 20 is reduced, and the possibility of the user falling into a dangerous situation due to the rescue operation being performed is reduced. can be suppressed.

Furthermore, during the rescue operation control, the movement control unit 117 performs control to move the car 20 at a safe and sufficiently slow speed, such as a speed slower than the normal traveling speed, for example, less than half the normal speed. Thereby, even if the car 20 is moved in a situation where the door is not properly closed, it is possible to reduce the possibility that the user will be in danger.

[Elevator 2]
As shown in FIG. 1, the elevator 2 includes a car 20, a communication section 21, a control section 22, a drive section 23, a hall door 28, and an operation section 26. The communication unit 21 is a communication module for the control unit 22 to communicate with the elevator control device 1 . The drive unit 23 is a drive member for moving the car 20 between floors, and moves the car 20 by operating under the control of the control unit 22. The operating unit 26 is provided for each landing on each floor, and transmits a hall call based on the operation on the operating unit 26 to the elevator control device 1. The landing door 28 is provided at each landing, and opens and closes in conjunction with the opening and closing of the door 24 of the car 20.

The control unit 22 transmits a signal indicating the operation performed on the operation unit 26 to the elevator control device 1. For example, the control unit 22 transmits a car call including information specifying the destination floor of the car 20 to the elevator control device 1 based on the operation on the operation unit 26 .

Further, the control unit 22 transmits a signal indicating which operation unit 26 is being operated to the elevator control device 1. Thereby, the elevator control device 1 can recognize that a specific button has been operated during rescue operation control.

(Car 20)
FIG. 4 is a schematic diagram showing an example of the internal configuration of the car 20. The car 20 opens and closes a door 24 based on control from the elevator control device 1. As shown in FIG. 4, the car 20 of the elevator 2 includes a door 24, a presentation section 25, an operation section 26, and a detection section 27.

The door 24 is a door 24 provided in the car 20 and opens and closes under the control of the control unit 22. The operation unit 26 is a button provided in the car 20, and includes, for example, a button for specifying a floor for making a car call, a button for issuing an instruction to open and close the door 24, and the like.

The operating section 26 that can accept operations during rescue driving control may be a specific button of the operating section 26, for example, the operating section 26A shown in FIG. 4. For example, the operation unit 26 that can accept operations during rescue operation control may be at least one of a button for instructing closing or opening of the door 24, and a button for instructing a destination floor. The control unit 22 of the elevator 2 may notify the user that the button that can accept an operation during the rescue operation control blinks, or the like, to inform the user that the button is a button that should be operated during the rescue operation control. Buttons other than buttons that can accept input operations for rescue operation control, such as buttons for instructing the opening operation of the door 24 (represented by reference numeral 26B in FIG. 4), are turned off during rescue operation control and are in a state in which no operations are accepted. Become. By allowing only specific buttons to accept operations, it is possible to reduce the possibility that a rescue operation will be performed due to an erroneous operation.

The presentation unit 25 is a display device such as a display that can present various information, or a device such as a speaker that can output audio. The presentation unit 25 presents various information transmitted from the elevator control device 1 under the control of the control unit 22 . This allows the user in the car 20 to recognize necessary information.

The detection unit 27 is, for example, a car door switch that is turned on and off in accordance with the opening and closing of the door 24. Specifically, while the door 24 is opened beyond a preset threshold, the detection unit 27 is turned off and the door is closed. It is on while 24 is closed. When the door 24 is opened while the car 20 is running, the detection unit 27 is turned off. When the detection unit 27 is switched on and off, the control unit 22 transmits a signal to the elevator control device 1 indicating that the state of the detection unit 27 has been switched on or off.

<An example of the flow of processing performed in the elevator control system 100>
FIG. 5 is a flowchart showing an example of the flow of processing (elevator control method) performed by the elevator control system 100. Hereinafter, an example of the flow of processing performed by the elevator control system 100 when an abnormality occurs in the operation of the elevator 2 will be described using FIG. 5.

In the elevator 2, when the detection section 27 detects that the door 24 has opened beyond a predetermined value, specifically, when the car door switch, which is the detection section 27, is turned off, the control section 22 A signal indicating the detection result of the detection unit 27 is transmitted to the elevator control device 1 . If the reception timing of the signal is when the car 20 is moving, the abnormality detection unit 112 of the elevator control device 1 detects that an abnormality has occurred in the operation of the elevator 2 (YES in S1: abnormality detection step).

Subsequently, the abnormality detection unit 112 outputs information indicating that an abnormality has been detected in the operation of the elevator 2 to each part of the control unit 11. Thereby, control for ensuring the safety of the users in the car 20 is started in the elevator control device 1. When the movement control unit 117 acquires information indicating that an abnormality related to the operation of the elevator 2 has been detected, it transmits a signal to the drive unit 23 instructing to stop the movement of the car 20 (S2). Thereby, the control unit 22 of the elevator 2 stops the movement of the car 20.

After stopping the movement of the car 20, the information presentation control section 114 sends a signal to the control section 22 of the elevator 2 instructing to present a message prompting the user to press the operation section 26 to close the door 24. Send. As a result, the message is displayed on the presentation section 25 of the car 20. When the operation unit 26 for instructing to close the door is pressed after the message is displayed, the door control unit 113 transmits a signal to the control unit 22 of the elevator 2 for instructing to close the door 24. As a result, the control section 22 attempts to close the door 24 of the car 20.

After displaying the message on the presentation unit 25, the movement control unit 117 acquires the detection result of the detection unit 27 indicating the open/closed state of the door 24. When the door 24 is closed, in other words, when the car door switch which is the detection unit 27 is turned on (YES in S3), the movement control unit 117 causes the travel distance identification unit 115 to determine the travel distance of the car 20. Outputs a signal instructing the identification of the On the other hand, if the door 24 is not closed, in other words, if the car door switch, which is the detection unit 27, continues to be off (NO in S3), the movement control unit 117 stops the car 20. Finish the process. Note that the movement control unit 117 may perform the process of S3 multiple times.

When the traveling distance specifying unit 115 acquires the signal, it specifies the traveling distance of the car 20 from the start of movement immediately before the abnormality is detected to the stop when the abnormality is detected (S4).

The movement control unit 117 acquires information indicating the distance traveled by the car 20 from the distance determining unit 115, and determines the moving direction of the car 20 based on the distance traveled (S5 to S7). If the travel distance of the car 20 is equal to or greater than the predetermined value (NO in S5), the movement control unit 117 determines the moving direction of the car 20 to be the direction in which the car 20 was moving (S6). On the other hand, if the traveling distance of the car 20 is less than the predetermined value (YES in S5), the movement control unit 117 determines the moving direction of the car 20 to be the direction opposite to the direction in which the car 20 was moving. (S7).

Thereafter, when an operation input is performed on a specific operation section 26 of the car 20, the control section 22 of the elevator 2 transmits an operation signal to the elevator control device 1 via the communication section 21.

When the operation detection unit 116 receives the operation signal from the control unit 22, it outputs information indicating that an operation input is being performed in the car 20 to each part of the control unit 11 of the elevator control device 1. Thereby, the rescue operation is executed in the elevator control device 1.

When the door control unit 113 acquires information indicating that an operation input is being performed on the car 20 (YES in S8), the door control unit 113 closes the door 24 and sets the door closing torque in the direction of closing the door 24 to the normal operation. A signal is transmitted to the car 20 instructing the door closing torque to be larger than the door closing torque at the time (S9). When the control unit 22 of the elevator 2 receives the signal, it closes the door 24 with a torque larger than the door closing torque during normal operation.

The information presentation control unit 114 transmits to the control unit 22 of the elevator 2 at least one of the moving direction and the distance or time to the nearest floor when performing rescue operation control. The control unit 22 of the elevator 2 controls the presentation unit 25 to present the received information to the user (S10).

When the movement control unit 117 acquires information indicating that an operation input is being performed on the car 20, the movement control unit 117 sends a signal to the drive unit 23 instructing to move the car 20 in the direction determined in step S6 or step S7. Send to. The control unit 22 of the elevator 2 moves the car 20 in the instructed direction (S11: movement control step).

The control to close the door 24 and the control to move the car 20 are performed only while an operation input is being made to the operation unit 26. When no operation input is made to the operation unit 26, for example, when the user releases the operation unit 26, the door control unit 113 applies the door closing torque in the direction of closing the door 24 to the door closing torque during normal operation. Control to instruct the torque to be greater than the closing torque is canceled. Furthermore, the movement control unit 117 cancels the control that instructs to move the car 20 in the determined direction. When the user presses the operation unit 26 again, the door control unit 113 and the movement control unit 117 resume the control to close the door 24 and the control to move the car 20.

When the car 20 moves in the instructed direction and arrives at the nearest floor (YES in S12), the movement control unit 117 issues an instruction to stop the car 20, and the door control unit 113 closes the door of the car 20. 24 and landing door 28 to be opened. Thereby, the user can get off the car 20 and arrive at the landing on the nearest floor.

Note that in the above description, if the door 24 is not closed in S3, the process ends with the car 20 stopped, but the process is not limited to this. For example, if a camera is installed in the car 20 and the situation inside the car 20 can be checked from the monitoring center, the following process may be performed. First, a supervisor at the surveillance center transmits a signal to the control unit 11 from the control device at the surveillance center to permit manual operation while checking the image obtained from a camera installed in the car 20. When the control unit 11 receives this signal, it performs the processing from S4 onwards. Further, an operation instruction may be given to the user inside the car 20 by the watchman.

This makes it possible to execute the movement control in the event of an abnormality in a state in which the supervisor at the monitoring center confirms that there is no problem even if the process of S9 or S11 is executed.

[Embodiment 2]
Other embodiments of the invention will be described below. For convenience of explanation, members having the same functions as the members described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated.

<Configuration of elevator control system 100A>
FIG. 6 is a functional block diagram showing an example of the configuration of an elevator control system 100A according to the second embodiment. In the elevator control system 100A, when an abnormality regarding the operation of the elevator 2A occurs, the door 28 of the landing door 28 installed at the landing where the car 20 was stopped at the start of movement immediately before the abnormality was detected is detected. The car 20 moves based on the detection result.

In addition to the configuration of the elevator 2, the elevator 2A includes a detection unit 30 at each landing. The detection unit 30 may be a door switch similar to the detection unit 27 provided in the car 20. The detection section 30, like the detection section 27 of the car 20, is turned on when the door is closed and turned off when the door is open.

The elevator control device 1A differs from the elevator control device 1 in that it includes a control section 11A. The control unit 11A includes a movement control unit 117A instead of the movement control unit 117.

The movement control unit 117A determines whether the car 20 is closed at the time of the abnormality detection based on the detection result of a door closing failure of the landing door 28 provided at the landing at the time of the start of the movement in which the car 20 was stopped at the time of the movement start immediately before the abnormality detection. A moving direction is determined when performing rescue operation control to move the car 20 to a predetermined landing floor after it has stopped.

When an abnormality occurs in the elevator 2A, the movement control unit 117A acquires the detection result of the detection unit 30 provided at the landing at the time of movement start. Specifically, it is determined whether a door switch, which is a detection unit 30 provided on the floor from which the car 20 departed immediately before, is on or off. If the detection unit 30 provided at the landing at the start of movement is off, the movement control unit 117A determines that a door closing failure of the landing door 28 provided at the landing at the start of movement has been detected, and prevents the movement of the car 20 from occurring. The direction is determined to be the opposite direction to the direction in which it was moving before the abnormality was detected. When the detection unit 30 provided at the landing at the start of movement is on, the movement control unit 117A determines that a door closing failure of the landing door 28 provided at the landing at the start of movement is not detected, and stops the movement of the car 20. The direction is determined to be the direction in which the vehicle was moving before the abnormality was detected.

The movement control unit 117A controls the movement of the car 20 based on the determined direction. Specifically, if a door closing failure of the landing door 28 provided at the landing at the time of movement start is detected, the movement control unit 117A moves the movement in the opposite direction to the direction in which the landing door 28 provided at the landing is detected. Control is performed to move the car 20 in the direction in which the car 20 was moving before the abnormality was detected, if a door closure failure of the landing door 28 provided at the landing is not detected at the time of the start of movement. conduct.

7 and 8 are schematic diagrams showing an example of a state when an abnormality related to operation occurs in the elevator 2. FIG. 7 shows the state of the car 20 when a door closure failure of the landing door 28 provided at the landing at the start of movement is detected, and FIG. 28 shows the state of the car 20 when door closing failure of No. 28 is not detected. Note that both FIGS. 7 and 8 show an example in which the car 20 moves upward from the first floor as the starting floor, and the landing is on the first floor at the start of movement.

If a door closure failure is detected in the landing door 28 (28A) provided at the landing at the start of movement, as shown in FIG. It is possible that X1 is stuck. In this case, when the car 20 is moved in the direction in which it was moving before the abnormality was detected, the caught obstacle X1 is pulled by the landing door 28 and the door 24 of the car 20, and the obstacle , or the abnormal situation may worsen, such as damage to the landing door 28. In addition, if the obstacle X1 is, for example, a pet lead, and the pet is left behind at the landing, if the car 20 is moved in the direction in which it was moving before the abnormality was detected, the car 20 will The leash may be pulled and your pet may be in danger.

Here, if a door closing failure is detected in the landing door 28 (28A) provided at the landing at the time of movement start, the detection unit 30 (30A) corresponding to the landing door 28A detects that the switch is turned off. A signal indicating this is transmitted to the elevator control device 1A. As a result, the movement control unit 117 performs control to move the car 20 in the opposite direction to the direction in which it was moving before the abnormality was detected. Thereby, the elevator control system 100A can perform a rescue operation without aggravating the abnormal situation.

In addition, if a door closing failure is not detected in the landing door 28 (28A) provided at the landing at the start of movement, as shown in FIG. 8, when the car 20 passes near the specific tower equipment X2 There is a possibility that the car 20 came into contact with the tower equipment X2.

If a door closing failure is not detected in the landing door 28 (28A) provided at the landing at the start of movement, the detection unit 30 (30A) corresponding to the landing door 28A indicates that the switch is turned on. A signal is transmitted to the elevator control device 1A. As a result, the movement control unit 117 performs control to move the car 20 in the direction in which it was moving before the abnormality was detected. Thereby, in the elevator control system 100A, the rescue operation can be performed while reducing the possibility of causing an abnormal situation such as the car 20 coming into contact with the in-tower equipment X2 again.

<An example of the flow of processing performed in the elevator control system 100A>
FIG. 9 is a flowchart showing an example of the flow of processing performed by the elevator control system 100A. Hereinafter, an example of the flow of processing performed by the elevator control system 100A will be described using FIG. 9.

Steps S21 to S23 are the same as steps S1 to S3 in the control of the elevator control system 100 described with reference to FIG. 5 in the first embodiment, so the explanation will be omitted.

When an abnormality regarding the operation of the elevator 2A is detected, the movement control unit 117A receives a signal from the detection unit 30 indicating whether the door switch, which is the detection unit 30, is on or off, that is, when the movement starts. A signal indicating the status of the landing door 28 provided is received.

The movement control unit 117A determines the moving direction of the car 20 based on the signal (S24 to S25). If a closing failure of the landing door 28 provided at the landing at the start of movement is not detected (NO in S24), the movement control unit 117A changes the moving direction of the car 20 to the direction in which the car 20 was moving. It is determined (S25). On the other hand, if a door closure failure of the landing door 28 provided at the landing at the start of movement is detected (YES in S24), the movement control unit 117A determines whether the car 20 is moving in the moving direction of the car 20. The direction is determined to be the opposite direction (S26).

The control after determining the moving direction of the car 20 (steps after S27) is the same as the control after step S8 in the control of the elevator control system 100 explained using FIG. 5 in the first embodiment. The explanation will be omitted.

[Embodiment 3]
Still other embodiments of the present invention will be described below.

<Configuration of elevator control system 100B>
FIG. 10 is a functional block diagram showing an example of the configuration of an elevator control system 100B according to the third embodiment. As shown in FIG. 10, the elevator control system 100B includes an elevator control device 1B and an elevator 2A. In the elevator control system 100B, when an abnormality regarding the operation of the elevator 2A occurs, the distance traveled by the car 20 and the information provided at the landing where the car 20 was stopped at the start of movement immediately before the detection of the abnormality are determined. The car 20 is moved based on the detection result that the landing door 28 is not properly closed. The elevator control device 1B includes a control section 11B having a travel distance specifying section 115 and a movement control section 117B.

The movement control unit 117B determines (1) the travel distance of the car 20 from the start of movement immediately before the abnormality is detected to the stop when the abnormality is detected, and (2) the travel distance of the car 20 when the movement starts immediately before the abnormality is detected. Rescue operation control is performed to move the car 20 to a predetermined landing floor after the car 20 has stopped when an abnormality is detected, based on both the detection results of a door closing failure of the landing door 28 provided at the landing that was stopped at the start of movement. Determine the direction of movement when doing so.

Specifically, when the abnormality detection unit 112 detects that an abnormality has occurred in the elevator 2A, the movement control unit 117B acquires information indicating the travel distance. If the travel distance is equal to or greater than the predetermined value, the movement control unit 117B determines the moving direction of the car 20 to be the direction in which the car 20 was moving. When the travel distance is less than a predetermined value, the movement control unit 117B detects the detection result of the detection unit 30 corresponding to the landing door 28 provided at the landing at the time of movement start (whether the door switch is on or off). Receive a signal indicating.

If a closing failure of the landing door 28 provided at the landing at the time of movement start is detected, the movement control unit 117B changes the moving direction of the car 20 to the direction opposite to the direction in which it was moving before the abnormality was detected. decided on. If a closing failure of the landing door 28 provided at the landing at the start of movement is not detected, the movement control unit 117B determines the movement direction of the car 20 to be the direction in which it was moving before the abnormality was detected.

Note that the order in which the moving direction of the car 20 is determined based on the travel distance and the determination of the moving direction of the car 20 based on the detection result of the door closing failure of the landing door 28 is not limited to this, but may be performed in the reverse order. May be done. Specifically, when the abnormality detection unit 112 detects that an abnormality has occurred in the elevator 2A, the movement control unit 117B detects the detection unit 30 corresponding to the landing door 28 provided in the landing at the time of movement start. Receive a signal indicating the result. If a closing failure of the landing door 28 provided at the landing at the time of movement start is detected, the movement control unit 117B changes the moving direction of the car 20 to the direction opposite to the direction in which it was moving before the abnormality was detected. decided on. If a door closing failure of the landing door 28 provided at the landing at the start of movement is not detected, the movement control unit 117B acquires information indicating the travel distance.

If the traveling distance is less than the predetermined value, the movement control unit 117B determines the moving direction of the car 20 to be the direction opposite to the direction in which the car 20 was moving. If the travel distance is equal to or greater than the predetermined value, the movement control unit 117B determines the moving direction of the car 20 to be the direction in which the car 20 was moving.

The movement control unit 117B performs control to move the car 20 in the direction determined as described above. In other words, the movement control unit 117B (1) moves the car 20 in the opposite direction to the direction in which it was moving up to the time of detection of the abnormality when the travel distance is less than the predetermined value, so that the travel distance is equal to or greater than the predetermined value. In the case of (2) control to move the car 20 in the direction in which it was moving before the abnormality was detected, and (2) when a door closure failure of the landing door 28 provided at the landing at the time of movement start is detected. Then, if the car 20 is moved in the opposite direction to the direction in which it was moving before the abnormality was detected, and if no door closure failure of the landing door 28 provided at the landing is detected at the start of movement, the abnormality is detected. At least one of the following is performed: control to move the car 20 in the direction in which it was previously moving.

Thereby, the elevator control device 1A can move the car 20 in an appropriate direction based on the travel distance of the car 20 and the detection result of the detection unit 30.

<An example of the flow of processing performed in the elevator control system 100B>
FIG. 11 is a flowchart showing an example of the flow of processing performed by the elevator control system 100B. Hereinafter, an example of the flow of processing performed by the elevator control system 100B will be described using FIG. 11.

Steps S41 to S43 are the same as steps S1 to S3 in the control of the elevator control system 100 described with reference to FIG. 5 in the first embodiment, so the explanation will be omitted.

Upon acquiring information indicating that an abnormality has been detected in the operation of the elevator 2, the traveling distance identifying unit 115 determines the traveling distance of the car 20 from the start of movement immediately before the abnormality was detected to the stop when the abnormality was detected. is specified (S44).

The movement control unit 117B determines the moving direction of the car 20 based on the traveling distance of the car 20 and the detection result of a door closing failure of the landing door 28 provided at the landing at the time of movement start (S45 to S48). First, the movement control unit 117B acquires information indicating the distance traveled by the car 20 from the distance determining unit 115, and determines the moving direction of the car 20 based on the distance traveled. If the travel distance of the car 20 is equal to or greater than the predetermined value (NO in S45), the movement control unit 117B determines the moving direction of the car 20 to be the direction in which the car 20 was moving (S46).

On the other hand, if the traveling distance of the car 20 is less than the predetermined value (YES in S45), the movement control unit 117B determines from the detection unit 30 whether the door switch, which is the detection unit 30, is on or off. In other words, a signal indicating the state of the hall door 28 provided at the hall at the start of movement is received.

If a closing failure of the landing door 28 provided at the landing at the start of movement is not detected (NO in 47S), the movement control unit 117B changes the moving direction of the car 20 to the direction in which the car 20 was moving. It is determined (S46). On the other hand, if a door closure failure of the landing door 28 provided at the landing at the start of movement is detected (YES in S47), the movement control unit 117B controls whether the car 20 is moving in the moving direction of the car 20. The direction is determined to be the opposite direction (S48).

The control after determining the moving direction of the car 20 (steps after S49) is the same as the control after step S8 in the control of the elevator control system 100 explained using FIG. 5 in the first embodiment. The explanation will be omitted.
