The operation control unit (4) performs, as the evacuation operations, escape operations that move an elevator car between a rescue floor where the passengers are and an escape floor from which escape to the exterior of the building is possible, up until a first evacuation reference time that is earlier by a first evacuation time than the tsunami estimated arrival time included in the emergency tsunami information.

Description

Elevator control device and elevator control method

The present invention relates to an elevator control device that controls the operation of an elevator and an elevator control method.

Conventionally, when information on inundation damage is transmitted from the monitoring center to the elevator control device, the operation of the inundation detector installed in the building is started, and when the inundation detector detects inundation, the operation mode of the elevator An elevator disaster prevention system that switches from a normal operation mode to a disaster operation mode is known (see Patent Document 1).

JP 2004-203562 A

However, for example, when a tsunami occurs due to an earthquake, the rising speed of the water level after the start of inundation in the building is extremely fast, so in the conventional elevator disaster prevention system as described above, after the inundation detector detects the inundation, Even if the operation mode is switched to the disaster operation mode, the elevator cannot be sufficiently operated in the disaster operation mode.

The present invention has been made to solve the above-described problems, and provides an elevator control system that can evacuate passengers in a building earlier and prevent evacuation delay of passengers. The purpose is to obtain.

The elevator control apparatus according to the present invention includes a receiving unit that receives emergency tsunami information, and an operation control unit that performs an evacuation operation for evacuating passengers in a building based on the emergency tsunami information. Up to the first evacuation reference time that is earlier than the predicted tsunami arrival time included in the emergency tsunami information by the first evacuation time, the car makes a round trip between the rescue floor where passengers are present and the escape floor that can escape outside the building. The escape operation to be moved is performed as an evacuation operation.

In the elevator control method according to the present invention, after the emergency tsunami information is received by the receiving unit, the passengers are not allowed until the first evacuation reference time that is earlier than the tsunami arrival predicted time included in the emergency tsunami information by the first evacuation time. A step of performing an escape operation for reciprocating the car between an existing rescue floor and an escape floor that can escape to the outside of the building; after the first evacuation reference time has elapsed, a second evacuation time than the predicted tsunami arrival time Up to the second evacuation reference time as early as possible, if the predicted tsunami height included in the emergency tsunami information is lower than the height of the top floor of the building, the upper evacuation floor and the rescue located at a position higher than the predicted tsunami height Closed floor stop operation that stops the car at the nearest floor when the predicted tsunami height is higher than the position of the top floor of the building. Performing a second evacuation After a quasi-time, even when the tsunami prediction height is lower than the height of the building location comprises the step of performing the operation nearest floor stop.

According to the elevator control device and the elevator control method of the present invention, the passenger escapes to the rescue floor and the building where the passenger exists until the first evacuation reference time that is earlier than the tsunami arrival predicted time by the first evacuation time. Because the escape operation to reciprocate the car to and from the possible escape floor is performed, passengers in the building can be evacuated earlier in the event of a tsunami, and prevention of passenger evacuation delays Can do.

It is a block diagram which shows the control apparatus of the elevator by Embodiment 1 of this invention. It is a flowchart which shows the control method of the elevator by the control apparatus of FIG.

Preferred embodiments of the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an elevator control apparatus according to Embodiment 1 of the present invention. In the figure, an elevator installed in a building has a car (not shown) that moves up and down in a hoistway and a control device 1 that controls the movement of the car. The elevator control device 1 includes a receiving unit 3 that receives emergency tsunami information 2 and an operation control unit that performs an evacuation operation for evacuating passengers in a building based on the emergency tsunami information 2 received by the receiving unit 3. 4.

The emergency tsunami information 2 includes information on the predicted tsunami arrival time and the predicted tsunami height corresponding to the area where the building where the elevator is installed exists. The predicted tsunami arrival time is the time at which the tsunami is predicted to reach the building. The predicted tsunami height is a predicted value of the height of the tsunami that reaches the building. The emergency tsunami information 2 is sent to the receiving unit 3 via a communication network from a predetermined information providing server installed in a monitoring center outside the building, for example.

The receiving unit 3 receives the emergency tsunami information 2 from the information providing server as numerical data, for example. The operation control unit 4 sets the operation of the elevator as normal operation when reception of the emergency tsunami information 2 by the reception unit 3 is avoided, but when the reception unit 3 receives the emergency tsunami information 2, the operation control unit 4 includes the emergency tsunami information 2. Based on the estimated tsunami height, the necessity of evacuation operation is determined, and when it is determined that evacuation operation is necessary, the elevator operation is switched from normal operation to evacuation operation. In addition, the operation control unit 4 includes a storage unit 5, a determination unit 6, and an operation management unit 7.

The storage unit 5 stores in advance setting information related to the building where the elevator is installed. The setting information includes information on an evacuation operation reference height for determining whether or not an evacuation operation is necessary, information on a height related to a building, information on a first evacuation time, and information shorter than the first evacuation time. 2 evacuation time information.

The height information about the building includes information on the height of the position of each floor in the building. The first evacuation time is a time required for a passenger who has escaped from the building to reach a place higher than the predicted tsunami height. Therefore, the first evacuation time is set in advance in consideration of, for example, the topography around the building, the position of another building, and the like. The first evacuation time may be set as a fixed time regardless of the predicted tsunami height, or may be set for each predicted tsunami height (for example, every 1 m) depending on the difference in predicted tsunami height. Good. The second evacuation time is the time required to move the car to the upper evacuation floor located at a position higher than the predicted tsunami height. The second evacuation time may be set as a fixed time regardless of the predicted tsunami height, or may be set for each predicted tsunami height (for example, every 1 m) according to the difference in predicted tsunami height. Good.

The determination unit 6 determines whether or not the evacuation operation is necessary based on the emergency tsunami information 2 from the reception unit 3 and the setting information from the storage unit 5. That is, the determination unit 6 compares the predicted tsunami height included in the emergency tsunami information 2 with the evacuation operation reference height included in the setting information, and the evacuation operation is performed when the predicted tsunami height is lower than the evacuation operation reference height. It is determined that it is not necessary, and it is determined that evacuation operation is necessary when the predicted tsunami height is equal to or higher than the evacuation operation reference height.

Further, when the determination unit 6 determines that the evacuation operation is necessary, the rescue unit in which the passenger is present is based on the emergency tsunami information 2 from the reception unit 3 and the setting information from the storage unit 5. Escape operation (first operation) that moves the car back and forth between the floor and the escape floor that can escape to the outside of the building (for example, the first floor that is the entrance floor), the upper retreat floor that is higher than the predicted tsunami height Any of the upward evacuation operation (second operation) for reciprocating the car between the car and the rescue floor and the nearest floor stop operation (third operation) for stopping the car at the nearest floor To decide whether to use evacuation operation.

Specifically, when the time from the current time to the predicted tsunami arrival time is equal to or longer than the first evacuation time (that is, the first evacuation time earlier than the predicted tsunami arrival time) Until the evacuation reference time is determined). Further, the determination unit 6 determines that the time from the current time to the predicted tsunami arrival time is shorter than the first evacuation time and equal to or longer than the second evacuation time (that is, after the first evacuation reference time has elapsed). If the predicted tsunami height is lower than the height of the top floor of the building, the upward evacuation operation is evacuated when the predicted tsunami height is lower than the height of the top floor of the building. If the predicted tsunami height is equal to or higher than the height of the top floor of the building, it is determined that the nearest floor stop operation is an evacuation operation. Furthermore, when the time from the current time to the predicted tsunami arrival time is shorter than the second evacuation time (that is, after the second evacuation reference time has elapsed), the determination unit 6 does not depend on the predicted tsunami height. It is determined that the nearest floor stop operation is evacuation operation. The upper retreat floor is determined by the determination unit 6 by comparing the height of the position of each floor with the predicted tsunami height. For example, in a five-story building, if the predicted height of the tsunami exceeds the height of the second floor of the building but is lower than the height of the third floor, at least one of the third to fifth floors The floor is the upper retreat floor.

The operation management unit 7 manages the operation of the elevator based on the determination result by the determination unit 6. That is, the operation management unit 7 continues the normal operation of the elevator without the evacuation operation when the determination unit 6 determines that the evacuation operation is unnecessary, and the evacuation operation is necessary. When the determination is made by the determination unit 6, the elevator operation is switched from the normal operation to the evacuation operation. In addition, when the operation management unit 7 switches the elevator operation from the normal operation to the evacuation operation, the operation determined by the determination unit 6 among the escape operation, the upper evacuation operation, and the nearest floor stop operation is evacuated. Do as. When performing the escape operation and the upward evacuation operation, the operation management unit 7 specifies the rescue floor where the passenger is present based on the call registration status by operating the hall button device installed on each floor. The escape operation and the upward retreat operation performed by the operation management unit 7 are automatic reciprocating operations in which the car is automatically reciprocated. In addition, after the car is stopped at the nearest floor by the nearest floor stop operation performed by the operation management unit 7 and the passenger gets out of the car, the car is moved to a preset upper standby floor (for example, the top floor). After being moved, the operation of the elevator is suspended.

The building is provided with an inundation detection device 8 that detects inundation into the building when the water level in the building becomes a level that hinders the operation of the elevator. Information from the inundation detection device 8 is sent to the operation control unit 4. The operation control unit 4 controls the operation of the elevator based on information from the inundation detection device.

The operation control unit 4 determines whether or not the detection of inundation by the inundation detection device 8 has been canceled after the tsunami arrival prediction time has elapsed. The operation control unit 4 maintains the operation stop state in which the car is stopped at the standby floor when the inundation detection device 8 detects inundation after the tsunami arrival prediction time has elapsed, and the inundation occurs after the tsunami arrival prediction time has elapsed. When the detection of the inundation by the detection device 8 is cancelled, it is determined that there is no significant influence from the tsunami on the building, and the elevator operation is automatically returned from the operation suspension state to the normal operation.

Also, the building is provided with a notification device 9 for notifying information related to the operation of the elevator. In this example, notification devices are provided in the car and at the landings on each floor. As the notification device, for example, a speaker (sound generation device) that generates sound and a display (display device) that displays information are used. The operation control unit 4 controls the notification device when the operation of the elevator is an evacuation operation, and causes the notification device to notify the information about the operation of the elevator by voice or display.

The information about the operation of the elevator notified by the notification device includes the content of the evacuation operation (that is, the content of which operation of the escape operation, the upward evacuation operation and the nearest floor stop operation is the evacuation operation), And its purpose (escape operation is for the purpose of escaping outside the building, upper evacuation operation is for evacuation to the upper evacuation floor, and the nearest floor stop operation is evacuation on the stairs. To the extent that it is driving for the purpose).

Next, the operation will be described. FIG. 2 is a flowchart showing a method of controlling the elevator by the control device 1 of FIG. When the operation of the elevator is a normal operation (S1), it is determined by the control device 1 whether or not the emergency tsunami information 2 is received by the receiving unit 3 (S2). When the receiving unit 3 has not received the emergency tsunami information 2, the normal operation is continued as it is.

For example, when the receiving unit 3 receives the emergency tsunami information 2 from the information providing server when an earthquake occurs, the determination unit determines whether evacuation operation is necessary based on the predicted tsunami height included in the emergency tsunami information 2 (S3). When it is determined that the evacuation operation is unnecessary, the normal operation is continued as it is. When it is determined that the evacuation operation is necessary, the elevator operation is switched from the normal operation to the evacuation operation (S4). During the evacuation operation, information related to the evacuation operation is continuously notified from the notification device 9 under the control of the operation control unit 4.

Thereafter, the determination unit 6 determines whether the time from the current time to the predicted tsunami arrival time is equal to or shorter than the first evacuation time T1 (S5). When the time from the current time to the predicted tsunami arrival time is longer than the first evacuation time T1, the determination unit 6 determines that the escape operation for reciprocating the car between the escape floor and the rescue floor is the evacuation operation. The escape operation is performed by the operation management unit 7 (S6). As a result, the passenger can escape from the escape floor to the outside of the building in a state where time for evacuating to a place where the tsunami does not reach outside the building is secured.

Thereafter, whether the time from the current time to the predicted tsunami arrival time is equal to or shorter than the first evacuation time T1 until the time from the current time to the predicted tsunami arrival time becomes equal to or shorter than the first evacuation time T1. The determination (S5) and the execution of the escape operation (S6) are repeated.

When the time from the current time to the predicted tsunami arrival time is equal to or shorter than the first evacuation time T1, it is determined whether the time from the current time to the predicted tsunami arrival time is equal to or shorter than the second evacuation time T2. (S7).

When the time from the current time to the predicted tsunami arrival time is longer than the second evacuation time T2, it is determined whether or not the predicted tsunami height is equal to or higher than the height of the top floor of the building. (S8). As a result, when it is determined that the predicted tsunami height is lower than the height of the top floor of the building, the upward evacuation operation for reciprocating the car between the upper evacuation floor and the rescue floor is referred to as evacuation operation. The determination is performed by the determination unit 6, and the operation for upward retreat is performed by the operation management unit 7 (S9). Thereby, even when it is difficult to escape outside the building, passengers can be evacuated to a position higher than the predicted height of the tsunami.

Thereafter, when the upward evacuation operation is performed, the time from the current time to the predicted tsunami arrival time until the time from the current time to the predicted tsunami arrival time becomes equal to or shorter than the second evacuation time T2. The determination as to whether or not the second evacuation time T2 or less (S8) and the execution of the upward evacuation operation (S9) are repeated.

If the time from the current time to the predicted tsunami arrival time is less than or equal to the second evacuation time T2, or if the predicted tsunami height is higher than the height of the top floor of the building, The determination that the nearest floor stop operation to be stopped at the floor is the evacuation operation is performed by the determination unit 6, and the nearest floor stop operation is performed by the operation management unit 7 (S10). As a result, passengers in the car can get off at the landing on the nearest floor, preventing the passengers from being trapped in the car, and evacuating the passengers by the stairs of the building.

Then, after the car is moved to a preset upper standby floor (for example, the uppermost floor, etc.) under the control of the operation control unit 4, the operation of the elevator is stopped with the car stopped on the standby floor ( S11). Thereby, the possibility that the car will be submerged by the tsunami can be reduced.

After this, when the estimated tsunami arrival time has elapsed, it is determined by the operation control unit 4 whether or not the detection of inundation by the inundation detection device 8 has been canceled (S12). When the inundation detection device 8 detects inundation, the operation stop state in which the car is stopped on the standby floor is continued. On the other hand, when the detection of inundation by the inundation detection device 8 is cancelled, the operation control unit 4 automatically switches the elevator operation from the suspend operation state of the evacuation operation to the normal operation, assuming that there is no significant influence by the tsunami on the building. Will be restored. After the elevator operation automatically returns to the normal operation, the normal operation is performed again while the control device 1 determines whether or not the emergency tsunami information 2 has been received by the receiving unit 3.

In such an elevator control apparatus 1, the first floor evacuation time that is earlier than the predicted tsunami arrival time included in the emergency tsunami information 2 by the first evacuation reference time and the rescue floor where the passengers are located Since the escape operation that moves the car back and forth between the escape floors that can escape is performed as an evacuation operation, before the tsunami reaches the building, the passenger is escaped from the building to the place where the tsunami does not reach Time to evacuate can be secured. Thereby, the passenger in a building can be evacuated earlier, and a passenger's evacuation delay can be prevented.

Also, after the first evacuation reference time has elapsed, until the second evacuation reference time that is earlier than the tsunami arrival prediction time by the second evacuation time, the predicted tsunami height is higher than the height of the top floor position of the building. If the evacuation operation is performed as an evacuation operation, the upper evacuation operation that moves the car back and forth between the upper evacuation floor and the rescue floor, which is higher than the predicted tsunami height, is performed as the evacuation operation. The nearest floor stop operation that stops the car to the nearest floor is performed as an evacuation operation when it is higher than the height of the tsunami, so the estimated time of tsunami arrival approaches and secures time to evacuate passengers outside the building Even if it becomes impossible to do so, passengers can be evacuated in the building while preventing the confinement of passengers in the car.

In addition, when the second evacuation reference time has elapsed, the nearest floor stop operation is performed as an evacuation operation regardless of the predicted tsunami height, so that it is possible to prevent passengers from being trapped in the car.

Further, in such an elevator control method, after the emergency tsunami information 2 is received, the escape operation is performed until the first evacuation reference time. After the first evacuation reference time has elapsed, the second evacuation reference time is reached. Until the tsunami predicted height is lower than the height of the top floor of the building, the upward evacuation operation is performed, and when the predicted tsunami height is equal to or higher than the height of the top floor of the building, After the second evacuation reference time has passed, the nearest floor stop operation is performed regardless of the predicted height of the tsunami, so passengers in the building can be evacuated earlier, Passengers can be evacuated more reliably to places where the tsunami does not reach.

In the above example, as the evacuation operation until the second evacuation reference time after the lapse of the first evacuation reference time, the nearest tsunami height is lower than the height of the top floor position of the building. Although the floor stop operation is performed, in this case, the escape operation for reciprocating the car between the rescue floor and the escape floor may be continued instead of the nearest floor stop operation.

In the above example, when the receiving unit 3 receives the emergency tsunami information 2, the determination unit 6 determines whether or not evacuation operation is necessary based on the predicted tsunami height. When the information 2 is received by the receiving unit 3, the evacuation operation may always be performed without determining whether the evacuation operation is necessary.
