Description

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

  When a disaster occurs in a building where an elevator is installed, such as an earthquake or fire, generally the floor where the nearest service is provided to the car, that is, the car stops (passengers can get on and off) ) After moving the car to the floor, it is controlled to move the car to the floor (evacuation floor) where passengers can safely evacuate (control operation control).

  In addition, the control operation control when disasters occur in a complex manner is disclosed in Patent Document 1 below, for example. In Patent Document 1, in an emergency operation control device for an elevator, when an earthquake and a fire occur in the same time zone, and during the execution of one of the seismic control operation and the fire control operation, When an earthquake or fire corresponding to control operation is detected, the car is moved to the optimal floor and opened based on the position and direction of movement of the car in the controlled operation and information on the newly generated earthquake or fire. A composite control operation means for executing the control operation is disclosed.

  On the other hand, in recent years, buildings where elevators are installed are becoming increasingly tall. Moreover, in such high-rise buildings, for example, there are many that are generally open as the observation floor, for example. Many people who go to such a building only go to the observation floor and have no need for other floors in the building. Therefore, for security and other reasons, for example, an elevator that is operated directly from the entrance floor to the observation floor (hereinafter, such an elevator (car) is referred to as an “express car”) is installed. In such an express car, the floors other than the entrance floor and the observation floor are non-service floors, so they do not pass and stop (hereinafter such sections are referred to as “passing sections”). Only the floors of the floor and the observation floor are service floors.

JP 2009-230778 A

  However, the elevator operation control device disclosed in Patent Document 1 is not considered for use in a building where an express car is installed.

  That is, when an express car is provided, there is a non-service floor between the service floor and the service floor, and the express car operates so as to pass through the section of this non-service floor, that is, the passage section. Be controlled.

  For example, if the service floor is only the entrance floor and the observation floor, and if the car is passing the passage section when the control operation is started based on the disaster information, the nearest service floor It takes time to arrive. If this nearest service floor is the entrance floor (evacuation floor), passengers can be safely evacuated on this evacuation floor that has arrived even if it takes time.

  On the other hand, if the express car is moving in the direction away from the service floor which is the entrance floor, that is, toward the observation floor, move the elevator to the observation floor and then move again to the evacuation floor It takes a long time to evacuate passengers safely.

  The present invention has been made to solve the above problems, and the object of the present invention is when the control operation is started while the car is moving up and down the passage section in the direction opposite to the evacuation floor. It is intended to provide an elevator and an elevator control method capable of evacuating passengers in a car early and safely by reversing the ascending / descending direction in the passing section and moving to the evacuation floor.

  The first feature according to the embodiment of the present invention is that the elevator has a non-service floor where passengers are not allowed to get on and off between service floors where passengers are allowed to get on and off, and a passage section that passes through the non-service floor And a control device for controlling the operation of the express car, and a monitoring panel for transmitting the disaster information to the control device when a disaster occurs. When the disaster information from the panel is received, a judgment means for judging whether or not the express car is moving up and down in a direction away from the first service floor as the evacuation floor, Passenger detection means for detecting the presence of passengers in the express car and the second service floor where the express car can stop Arrival schedule And a calculation means for calculating a position where the express car is stopped when the estimated arrival time exceeds a predetermined time, and the express car is stopped based on the information on the calculated stop position, And an instruction creating means for creating an instruction to move the express car toward the first service floor.

  The second feature according to the embodiment of the present invention is that, in the elevator control method, the control device receives the disaster information from the monitoring panel, and the judgment means provided in the control device when the disaster information is received. The step of confirming the moving direction of the express car in relation to the first service floor, which is regarded as the evacuation floor, and the judging means move up and down toward the direction in which the express car leaves the first service floor If the passenger detection means detects the presence of passengers in the express car, and if the passenger detection means confirms the presence of passengers in the express car, the calculation means determines whether the passenger is in the express car. Calculating the estimated arrival time at the second service floor where the service can be stopped, and the determining means determines whether or not the estimated arrival time calculated by the calculating means exceeds a predetermined time. The And when the estimated arrival time exceeds a predetermined time, the calculation means calculates the position to stop the express car and stops the express car based on the information on the calculated stop position. And a step of moving the express car from the stop position toward the first service floor.

  According to the present invention, when the control operation is started while the car is moving up and down the passage section in the direction opposite to the evacuation floor, the lifting direction is reversed in the passage section to the evacuation floor. By moving the vehicle, it is possible to provide an elevator and an elevator control method capable of evacuating passengers in the car early and safely.

1 is an overall view showing an overall configuration of an elevator according to an embodiment of the present invention. It is a block diagram which shows the one part internal structure of the control apparatus in embodiment of this invention. It is a flowchart which shows the flow of the control method of the express car which concerns on embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an overall view showing an overall configuration of an elevator E according to an embodiment of the present invention. The elevator E includes a car 1 on which passengers ride, a control device 2 that controls the car 1, and a monitoring panel 3 that supplies disaster information to the control device 2.

  The passenger car 1 has a non-service floor where passengers are not allowed to get on and off between service floors where passengers are allowed to get on and off, and is an express ride having a passing section that passes between these service floors. It is a basket.

  In the embodiment of the present invention shown in FIG. 1, the express car 1 stops only on the first floor and the top floor as the entrance floor, and only these floors are service floors. On the other hand, the floor located between these floors is a non-service floor where the express car 1 passes without stopping. That is, the passage zone Z is between the entrance floor and the top floor.

  The entrance floor is a floor (evacuation floor) for evacuating passengers in the express car 1 when a disaster occurs. Therefore, in the embodiment of the present invention, this entrance floor is appropriately expressed as an evacuation floor or a first service floor X, and in the drawing, it is collectively expressed as an evacuation floor. On the other hand, the other service floor, here, the top floor is represented as the second service floor Y.

  The service floor where the express car 1 can be stopped can be arbitrarily set depending on the building where the elevator E is installed. Therefore, it may occur when a plurality of passage sections are provided. Further, the evacuation floor X is not necessarily the first floor, and may be, for example, the second floor or the first basement floor in relation to an adjacent building.

  In FIG. 1, the first service floor X and the second service floor Y are shaded. Further, the passing section Z is indicated by hatching.

  In addition, the express car 1 is controlled so as to stop only at the first service floor X and the second service floor Y as described above, but in the passage zone Z, for example, when an earthquake occurs, the express car An emergency stop floor for stopping the service car 1 may be provided (not shown in FIG. 1). A plurality of emergency stop floors may be provided in the passing section Z.

  The control device 2 drives each device constituting the elevator E, for example, a hoisting machine (not shown) that raises and lowers the express car 1 in the hoistway based on, for example, landing call registration and car call registration. To control. Also, the opening / closing of the elevator door of the express car 1 and the lighting of the indicator lamp are controlled.

  FIG. 2 is a block diagram showing an internal configuration of the control device 2. The control device 2 includes a receiving unit 21, a determining unit 22, a passenger detecting unit 23, a calculating unit 24, an instruction creating unit 25, and a transmitting unit 26.

  Note that the internal configuration of the control device 2 shown in FIG. 2 is only a part necessary for explaining the embodiment of the present invention, and as described above, for example, driving of a hoisting machine or the like is performed. The control means for controlling is not shown. The function of each constituent means will be described later.

  The monitoring panel 3 is connected to, for example, a fire alarm provided in a building (not shown), a center that is outside the building where the elevator E is installed, and that reports information related to earthquakes. The monitoring panel 3 receives disaster information about earthquakes and fires transmitted from these devices and centers and supplies the information to the control device 2. When receiving the disaster information transmitted from the monitoring panel 3, the control device 2 performs the control operation of the elevator E based on the transmitted disaster information.

  Next, the control flow of the elevator when the express car 1 is controlled will be described with reference to the flowchart shown in FIG. In addition, the function of each means in the control device 2 will be described together with the elevator control method.

  First, it is determined whether the control device 2 has received disaster information from the monitoring panel 3 (ST1). When disaster information is not received, it is not necessary to start the control operation in particular, and the normal operation is continued as before (ST2).

  On the other hand, when the control device 2 receives the disaster information from the monitoring panel 3 (YES in ST1), the determination means 22 confirms in which position in the hoistway the express car 1 is located. Specifically, first, it is determined whether or not the express car 1 is landing on either the first service floor X or the second service floor Y (ST3). When it is determined that the user is landing on the service floor (YES in ST3), it is further determined whether the user is currently landing on the first service floor (evacuation floor) X (ST4).

  When the express car 1 is landing on the first service floor (evacuation floor) X (YES in ST4), the determination means 22 is stopped at the first service floor (evacuation floor) X as it is. Is maintained via the instruction creating means 25, and the elevator door is further opened so that the passenger can evacuate from the express car 1.

  On the other hand, when the express car 1 is landing on the second service floor Y instead of the first service floor (evacuation floor) X (NO in ST4), the first service floor (evacuation floor) For example, an instruction is given to a hoisting machine (not shown) so as to go straight to X, and the express car 1 is moved through the passing section Z and led to the first service floor (evacuation floor) X (ST5). Then, the passenger is safely evacuated from the express car 1 or the building by opening the elevator door.

  If the express car 1 has not landed on any service floor (NO in ST3), it can be determined that the car is moving within the passing section Z. Therefore, the determination means 22 confirms whether the express car 1 is moving toward the first service floor X or moving toward the second service floor Y on the contrary. (ST6).

  When the judging means 22 confirms that the express car 1 is moving up and down in the direction opposite to the first service floor X, that is, toward the second service floor Y. Next, it is confirmed whether or not a passenger is on the express car 1 (ST8).

  Information necessary for confirming whether or not a passenger is in the express car 1 is acquired by the passenger detection means 23 and transmitted to the determination means 22. For example, a detection device 23 a that can detect the presence of a passenger such as a camera or a sensor is installed in the express car 1. The passenger detection means 23 receives the signal (information) from the detection device 23a. The received information regarding the presence or absence of a passenger is transmitted to the determination means 22 to determine the presence or absence of a passenger.

  Here, whether or not passengers are in the express car 1 depends on whether or not passengers are in the express car 1 as will be described later. This is because the method of operation control of this will change.

  First, when the judging means 22 judges that a passenger is in the express car 1 based on the information from the passenger detecting means 23 (YES in ST9), this passenger is being controlled. We must evacuate safely as soon as possible.

  Therefore, the determination means 22 causes the calculation means 24 to calculate the time until the express car 1 moving in the passage zone Z continues to move and arrives at the second service floor Y (ST10). ). The calculation means 24 is based on information such as the driving of the hoisting machine and the position of the express car 1, for example. The estimated time of arrival at the second service floor is calculated.

  After the estimated arrival time at the second service floor Y is calculated by the calculating means 24, the judging means 22 that has received the information compares it with a predetermined time, and uses the express within the predetermined time. It is determined whether or not the car 1 arrives at the second service floor Y (ST11).

  For example, there is an example in which the elevator E is installed in a 10-story building, where the first service floor X is the first floor and the second service floor Y is the 10th floor. In this case, the passing section is a section from the second floor to the ninth floor. When the express car 1 installed in such a building is moving in the passing section Z toward the 10th floor which is the second service floor Y, the control operation is at a position corresponding to the second floor. The operation control method differs depending on whether it is started or a position corresponding to the eighth floor.

  That is, in the former case (when control operation is started at a position corresponding to the second floor), the express car 1 is moved to the tenth floor, which is the second service floor Y, and then the first service is started again. Control to move to floor X cannot be adopted. The reason why the express car 1 is moved in the passing section Z over a long distance (time) is that it is often dangerous in a state where the control operation is performed.

  On the other hand, in the latter case (when control operation is started at a position corresponding to the 8th floor), that is, to the first service floor X which is an evacuation floor within a time when the safety of passengers can be secured. If it is possible to move, rather than suddenly braking and forcibly stopping and reversing the express car 1 that is moving in the hoistway, the express service goes to the 10th floor which is the second service floor Y. If the passenger car 1 is moved and then moved to the first service floor X, the load on passengers in the express car 1 can be reduced.

  Therefore, this judgment is made even if the express car 1 is moved to the first service floor X which is an evacuation floor after arriving at the second service floor Y under the control operation. It can be said that this is to determine whether or not

  The predetermined time can be set in advance. A plurality of predetermined times may be set according to the level of disaster understood from the disaster information transmitted from the monitoring panel 3. In the embodiment of the present invention, it is assumed that the storage means for storing the predetermined time is provided in the determination means 22, but there is no problem even if this storage means is provided separately. .

  In the judging means 22, the travel time of the express car 1 to the second service floor Y takes longer than a predetermined time, and the express car 1 cannot reach the second service floor Y within the predetermined time. (NO in ST11), the calculation means 24 is instructed to calculate the position at which the moving express car 1 can be stopped in the shortest time in the hoistway (ST12). ).

  In response to the instruction from the determination unit 22, the calculation unit 24 calculates a position where the express car 1 that is moving to the second service floor Y in the hoistway can be stopped in the shortest time (ST13). ). In this calculation, there are various factors such as the number of rotations of the hoist (speed of the express car 1) and the number of passengers in the express car 1 (weight of the express car 1). Is taken into consideration.

  In addition, in order to ensure the safety of passengers on the express car 1, the emergency car 1 that is moving in the hoistway is not braked forcibly and stopped forcibly. The position which can be stopped in the shortest while securing the property is calculated. In particular, since there is no normal check-in plate in the passage zone Z, it is difficult to perform detailed control to stop the express car 1 to land on the service floor. In consideration of the fact that passengers must be evacuated, the calculation is performed with an emphasis on passenger safety.

  When the position where the express car 1 can be stopped in the shortest time is calculated, the calculation means 24 transmits the calculation result to the determination means 22. Receiving the calculation result, the judging means 22 creates an instruction to be issued to each device of the elevator E in order to stop the express car 1 at the position calculated by the calculating means 24 with respect to the instruction creating means 25. Request (ST14). Each device is driven based on an instruction from the instruction creating unit 25, and the express car 1 is stopped at the position calculated by the calculating unit 24.

  The position where the express car 1 stops is an arbitrary position in the hoistway instead of the service floor as described above. Therefore, the stop is basically performed at a position where the receiving plate is not provided.

  The judging means 22 then gives instructions to each device for moving to the first service floor X, which is an evacuation floor, after stopping the express car 1 at the position calculated by the calculating means 24. Request is made to the instruction creating means 25 to create (ST15). By this instruction, the express car 1 stopped in the hoistway starts moving to the first service floor X, which is an evacuation floor, and goes straight (ST16).

  On the other hand, when it is determined that there are no passengers in the express car 1 (NO in ST9), or when it is possible to arrive at the second service floor Y within a predetermined time (the latter in the above example) In this case, the determination means 22 moves the express car 1 as it is to the second service floor Y, which is a floor that can be stopped (ST17). Therefore, after temporarily stopping (while the elevator door is closed), it is made to go straight to the first service floor X (ST16).

  Heretofore, the case where the express car 1 is moving in the direction away from the first service floor (evacuation floor) X in the passing section Z has been described, but the determination means 22 is the express car 1 As a result of determining the moving direction of the vehicle, if it is determined that the vehicle is moving to the first service floor (evacuation floor) X (NO in ST7), it goes straight to the first service floor (evacuation floor) X as it is. (ST16).

  By controlling the express car in this way, if the control operation starts when the car is moving up and down the passage section in the direction opposite to the evacuation floor, the direction of ascending and descending within the passage section It is possible to provide an elevator and an elevator control method capable of evacuating passengers in the car early and safely by moving the evacuation to the evacuation floor.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. For example, in the above-described step 17, when the emergency car moves to a floor where the emergency car can be stopped, if an emergency stop floor is provided in the hoistway, the second service floor and this emergency From the positional relationship between the stop floor and the express car, it may be controlled to stop at a floor closer to the first service floor.

  In addition, the explanation has been given by taking the case where one elevator (express car) is installed in the building as an example. However, when a plurality of elevators are installed or they are group-controlled. The elevator control method described in the embodiment of the present invention can be adopted even when a normal car that does not have an express car and a passing section is installed together. .

  Furthermore, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine the component covering different embodiment suitably.
