Definitions

  • the present invention relates to an elevator controller which carries out a control operation when a predefined disaster, such as shaking due to an earthquake or a fire, occurs in a building.
  • a predefined disaster such as shaking due to an earthquake or a fire
  • Some elevators carry out a control operation in order to rescue passengers in a car upon detection of the occurrence of a predefined disaster, such as shaking due to an earthquake, a fire or a flood.
  • a predefined disaster such as shaking due to an earthquake, a fire or a flood.
  • Patent Literature 1 As a conventional technique for an elevator provided with this function, there has been proposed, for example, an elevator which performs an earthquake emergency return operation after the occurrence of an earthquake (refer to Patent Literature 1). Specifically, in the elevator described in Patent Literature 1, as soon as an earthquake S wave of not less than a predefined value is detected, first, a car is forcibly stopped in the shaft. When the shaking of the building subsides to some extent, the run of the car is started to rescue the passengers in the car and the door is opened after the car is stopped at the nearest floor.
  • Patent Literature 1 Japanese Patent Laid-Open No. 2007-254036
  • a car when the occurrence of a disaster is detected, a car may sometimes be brought into an emergency stop in the shaft in order to prevent the expansion of damage. At this time, at some timing of an emergency stop, the car stops between floors.
  • the present invention was made to solve the problems described above, and it is an object of the invention to provide an elevator controller which, after an emergency stop of an elevator car is made in the event of the occurrence of a predefined disaster, can allow passengers to get off onto an appropriate floor in such a manner as to facilitate evacuation to outdoors as far as possible.
  • An elevator controller of the invention is an elevator controller which comprises a disaster detection device which detects a predefined disaster which occurs in a building, a run controller which, in the case where a disaster has been detected by the disaster detection device, brings an elevator car into an emergency stop on the basis of predefined stop conditions, and an evacuation-floor determination device which, in the case where the car has been brought into an emergency stop by the run controller, sets the degree of priority which indicates the easiness of evacuation of passengers after getting off the car for each floor to which the car is permitted to run from the standpoint of laws and regulations and physically, and determines an evacuation floor on the basis of the set degree of priority.
  • the run controller causes the car to run to the evacuation floor determined by the evacuation-floor determination device after bringing the car into an emergency stop on the basis of the stop conditions.
  • the elevator controller of the present invention it becomes possible to allow passengers to get off onto an appropriate floor in such a manner as to facilitate evacuation to outdoors as far as possible after an emergency stop of an elevator is made in the event of the occurrence of a predefined disaster.
  • FIG. 1 is a block diagram showing an elevator controller in a first embodiment according to the present invention.
  • This controller has the function of performing a control operation in the event of the occurrence of a predefined disaster in a building.
  • reference numeral 1 denotes a disaster detection device which detects a predefined disaster which occurs in a building, such as a fire, a flood or shaking due to an earthquake
  • reference numeral 2 denotes a control panel of an elevator provided in the building.
  • the disaster detection device 1 Upon detection of the occurrence of a predefined disaster in the building, the disaster detection device 1 outputs disaster detection information to the control panel 2. For example, in the case where a seismic sensor which senses the occurrence of an earthquake is provided in the building as the disaster detection device 1, the disaster detection device 1 outputs the information on the scale and the like of the earthquake which occurred as disaster detection information. In the case where a smoke detector or a fire detector is provided as the disaster detection device 1, the disaster detection device 1 outputs, for example, information on the floor where a fire occurred or on the specific place of occurrence of a fire and the like as disaster detection information.
  • the control panel 2 has the function of controlling the operation of an elevator, such as a normal operation of the elevator and a control operation during the occurrence of a disaster (hereinafter referred to as an "emergency operation"). Specifically, the control panel 2 is provided with an operation mode controller 3, a run controller 4, a restart determination device 5, an evacuation-floor determination device 6, a notification controller 7, and a passenger existence/absence determination device 8.
  • the operation mode controller 3 has the function of selecting an operation mode of the elevator on the basis of input information and the like and appropriately controlling the selected operation mode. For example, in the case where the occurrence of a disaster has not been detected by the disaster detection device 1, the operation mode controller 3 selects a normal operation as the operation mode of the elevator. Incidentally, when a normal operation has been selected by the operation mode controller 3, the control panel 2 carries out the control for causing (the car of) the elevator to sequentially respond to calls registered from halls and the car.
  • the operation mode controller 3 selects an emergency operation (an earthquake emergency return operation, a fire emergency return operation, a flood control operation or the like) as the operation mode of the elevator. That is, upon input of disaster detection information from the disaster detection device 1, the operation mode controller 3 selects an appropriate emergency operation on the basis of the inputted disaster detection information.
  • an emergency operation is selected by the operation mode controller 3, the control panel 2 performs a shift from a normal operation to the emergency operation and carries out an optimum control for the disaster which occurred.
  • the run controller 4 has the function of appropriately controlling a run and stop of the car of the elevator so as to suit the selected operation mode. For example, when a disaster has been detected by the disaster detection device 1, the run controller 4 brings the car of the elevator into an emergency stop on the basis of predefined stop conditions. That is, when an emergency operation has been selected by the operation mode controller 3, the run controller 4 makes a determination as to whether or not the stop conditions hold on the basis of the kind and scale of the disaster, the condition of the car (whether or not the car is running, car position and the like), and the condition of the safety device and the like. When the stop conditions hold, the run controller 4 brings the car which is running into an emergency stop.
  • the car when the car has been brought into an emergency stop, at some stop timing, the car may stop between floors (for example, the zone in which the hall door does not move in response to the opening and closing actions of the car door).
  • the restart determination device 5 makes a determination as to whether or not it is possible to cause the car to run again. For example, on the basis of the kind and scale of the disaster, and the condition of the safety device and the like, the restart determination device 5 makes a determination as to whether or not the restart conditions hold. When the restart conditions hold, the restart determination device 5 determines that the condition is such that the car can run again.
  • the evacuation-floor determination device 6 has the function of determining an evacuation floor for allowing the passengers in the car to get off in the case where an emergency stop of the car has been performed by the run controller 4. Specifically, when it is determined by the restart determination device 5 that the car can run again, the evacuation-floor determination device 6 specifies the zone in which a run of the car is possible at that point of time from the standpoint of laws and regulations and physically, and sets a predefined degree of priority for each floor in the specified zone.
  • the zone in which a run of the car is possible from the standpoint of laws and regulations and physically is fixed by a range of time presetting according to the disaster and the like (in which it is necessary to cause the car to land within a predefined period of time), limits to the running distance due to the remaining capacity of a battery during a power failure, and the like.
  • the degree of priority indicates the easiness of the evacuation of passengers after getting off the car, and for example, small (or large) values are set in the order of easiness after getting off.
  • the evacuation-floor determination device 6 determines the evacuation floor on the basis of the set degree of priority. For example, the evacuation-floor determination device 6 selects a floor which has obtained the smallest value (a high degree of priority) as an evacuation floor.
  • the run controller 4 causes the car to run toward the determined evacuation floor.
  • the run controller 4 performs a door opening action when the car arrives at the evacuation floor, and allows the passengers to get off.
  • the notification controller 7 has the function of controlling a notification device (not shown) which is provided in the car. For example, when an evacuation floor is determined by the evacuation-floor determination device 6 after an emergency stop of the car due to the detection of a disaster by the disaster detection device 1 (including the time during which the car is running to the above-described evacuation floor), the notification controller 7 causes the notification device to provide information to the effect that the car will run (is running) toward the evacuation floor and that the evacuation floor is a floor from which the passengers can easily evacuate after getting off.
  • the notification controller 7 causes the notification device to provide information useful for evacuation after getting off at the evacuation floor, such as how to evacuate from the elevator hall of the evacuation floor, and the evacuation route to get out of the hall to outdoors.
  • the notification device is intended for notifying the passengers in the car of predefined information, and is composed of an indication device, such as a liquid crystal display.
  • the passenger existence/absence determination device 8 has the function of determining the existence and absence of passengers in the car. Even in the case where a disaster is detected by the disaster detection device 1 and an emergency stop of the car has been made, if there is no passenger in the car, it is unnecessary to cause the car to run to a floor which is away from the stop position. For this reason, for example, when the absence of passengers in the car is detected by the passenger existence/absence determination device 8 upon an emergency stop of the car on the basis of the stop conditions, the run controller 4 causes the car to run to the floor which is the nearest from the stop position (the nearest floor). In such a case, it is not necessary for the evacuation-floor determination device 6 to carry out the setting of the degree of priority for each floor, or predefined control may be carried out in such a manner that the degree of priority of the nearest floor becomes highest.
  • the evacuation-floor determination device 6 makes a determination of an evacuation floor on the basis of the degree of priority and causes the car to run to the evacuation floor.
  • Figure 2 is a flowchart showing the actions of an elevator controller in the first embodiment according to the present invention.
  • the control panel 2 makes a determination on a constant basis as to whether or not the disaster detection device 1 has detected a disaster (S 101). If disaster detection information has not been inputted from the disaster detection device 1, the operation mode controller 3 selects a normal operation as the operation mode of the elevator (S102).
  • the operation mode controller 3 selects an emergency operation as the operation mode of the elevator. As a result of this, the control panel 2 starts the control for bringing the elevator into a pause.
  • the run controller 4 continues the run of the car as it is even after the input of the disaster detection information, and causes the car to stop at the nearest floor at the time of the occurrence of the disaster.
  • the control panel 2 After carrying out the control for allowing the passengers to get off at the nearest floor, the control panel 2 performs an elevator pause action for prohibiting the use of the elevator after that (from NO in S103 to S104).
  • the run controller 4 brings the car into an immediate stop in order to prevent the occurrence and expansion of damage.
  • the control panel 2 makes a determination as to whether or not the car has stopped between floors (S 103).
  • the control panel 2 carries out the control for allowing the passengers to get off at the floor, and performs an elevator pause action in order to prohibit the use of the elevator after that (S104).
  • the control panel 2 makes a determination by use of the restart determination device 5 as to whether or not the restart conditions hold (S 105).
  • the control panel 2 makes a determination by use of the passenger existence/absence determination device 8 as to whether or not there are passengers in the car (S 106).
  • the control panel 2 When the presence of passengers is detected in S106, the control panel 2 performs the control for stopping the car at an appropriate floor in consideration of the evacuation of the passengers to outdoors. For this purpose, when the presence of passengers is detected in S106, the evacuation-floor determination device 6 selects a floor which provides easiest evacuation to outdoors and sets the selected floor as the evacuation floor (S107). A concrete description will be given below of a method of setting an evacuation floor in S107.
  • the evacuation-floor determination device 6 specifies the zone in which a run of the car is possible at that point of time from the standpoint of laws and regulations and physically.
  • the evacuation-floor determination device 6 sets the degree of priority which indicates the easiness of evacuation after getting off for each floor present in the specified zone. Table 1 below shows an example of a method of setting the degree of priority.
  • Degree of priority Floor name Remarks High ⁇ ⁇ Low Main floor (entrance floor) Provides direct movement to and from outdoors Other floors Service floor The nearer to the main floor, the higher the degree of priority Service-cut floor An evacuation route may not be secured Floor with emergency landing exit in express zone An evacuation route may not be secured
  • the degree of priority is set in such a manner that, for example, the easier the movement from the elevator hall to outdoors, the higher the degree of priority. That is, a low degree of priority is set in the case where it is difficult to move from the elevator hall of the floor in question to outdoors without using an elevator.
  • a floor which is most suitable as an evacuation floor is a floor which enables any passenger to evacuate to outdoors after getting off, and the prime example is a main floor (an entrance floor).
  • the evacuation-floor determination device 6 sets the degree of priority of the main floor of a building at the highest level. Furthermore, for floors other than the main floor, the evacuation-floor determination device 6 sets the degree of priority of each floor in such a manner that the nearer to the main floor, the higher the degree of priority.
  • non-service floors for example, service-cut floors at which the car is prohibited from stopping in normal operations and floors with emergency landing exit installed at some midpoint of a express zone for the emergency escape of passengers.
  • the evacuation-floor determination device 6 sets the degree of priority of each floor in such a manner that for non-service floors, the degree of priority is lower than the degree of priority of service floors at which the car stops in normal operations.
  • the evacuation-floor determination device 6 considers also the damage condition of each floor due to the disaster which occurred and the like. For example, in the case where a fire occurs in a building, even when the passengers get off onto the floor where the fire has occurred, the passengers cannot evacuate from the hall where they got off to outdoors. For this reason, when the occurrence of a fire is detected by the disaster detection device 1, the evacuation-floor determination device 6 sets the degree of priority of each floor in consideration of the spread of the fire in the building so that the degree of priority of the floors which are far away from the floor where the fire occurred and are lower than the floor where the fire occurred, becomes high.
  • the evacuation-floor determination device 6 sets the degree of priority of each floor so that the degree of priority becomes high for the upper floors where the effect of the damage by the flood is less great.
  • the evacuation-floor determination device 6 may set the degree of priority also in consideration of the damage condition and degree of danger for each floor which occur due to each disaster. For example, in the case where a fire and another disaster occur simultaneously, for example, the evacuation-floor determination device 6 sets the degree of priority so that for the floor where the fire occurred the degree of priority is lower than the degree of priority of non-service floors.
  • the evacuation-floor determination device 6 sets a floor the nearest to the position where the car is at a standstill as an evacuation floor (S 1 08).
  • the run controller 4 When in S 107 or S 108 the setting of an evacuation floor is performed, the run controller 4 causes the car to start running toward the evacuation floor (S109). At this time, for example, the run controller 4 causes the car to run at a speed lower than the run speed during a normal operation, thereby preventing damage to the elevator equipment and secondary disasters from occurring.
  • the configuration may be such that also after the run of the car has been started in S109, the resetting of an evacuation floor is made possible by making the setting function of the degree of priority by the evacuation-floor determination device 6 effective.
  • the update processing of the degree of priority of each floor is performed by the evacuation-floor determination device 6 on the basis of each piece of input information.
  • the evacuation-floor determination device 6 determines a new evacuation floor on the basis of the newest degree of priority.
  • the run controller 4 causes the car to run toward the newly determined evacuation floor.
  • the notification controller 7 When in S 107 or S 108 the setting of an evacuation floor is performed, the notification controller 7 outputs a control instruction to the notification device in the car and provides various kinds of information useful for evacuation to the passengers in the car (S110).
  • the control panel 2 brings the elevator into a pause at that floor after performing a door opening action in order to cause the passengers in the car to get off onto the hall of the evacuation floor (S112).
  • the first embodiment of the present invention even in the case where an elevator is brought into an emergency stop in an emergency operation and the car stops between floors, if there are passengers in the car, a floor most suitable for evacuation to outdoors is selected as an evacuation floor and a run to the selected evacuation floor is started. For this reason, the passengers can escape to outdoors in a short time after getting off at the evacuation floor and it is possible to minimize damage due to disasters.
  • the degree of priority which is most suited to the building be set in consideration of various factors, such as the construction and evacuation system of the building and the condition and role of each floor.
  • an optimum evacuation floor may differ from time period to time period. In this case, all that is needed is that the evacuation-floor determination device 6 performs the setting of the degree of priority for each floor also in consideration of the time at which the disaster occurred (the car stopped between floors) and selects an evacuation floor most suitable for the time period.
  • the elevator controller of the present invention can be applied to an elevator controller which performs a control operation when a predefined disaster, such as shaking due to an earthquake or a fire, occurs in a building.
