Description

  Embodiments of the present invention relate to an elevator evacuation operation system in the event of a fire.

  Recently, when a fire has occurred in a building due to a rise in the height of the building, it has been considered to operate an elevator in order to quickly rescue the people left in the building.

  In such an evacuation operation of an elevator, it is assumed that a large number of evacuees get in the car when a fire occurs, but it is not always full. In addition, if it is assumed that the car will be full when a fire breaks out, respond to platform calls (hall calls) from floors other than fire floors (non-fire floors) within the loadable range. Become. For this reason, it becomes the form of the riding operation in normal time that the car stops and transports in each floor, and quick evacuation operation becomes difficult. Therefore, the conventional evacuation operation is mainly performed by reciprocating the non-fire floor and the evacuation floor by setting the specified load load value to a low value.

  However, since the elevator hoistway generally has a blow-off structure, when the building is filled with smoke during a fire, the hoistway is also filled with smoke. Therefore, it is expected that the reciprocating operation of the elevator can be performed only about several times. For this reason, if the number of evacuees at one time is limited to a small number, it cannot be said that the elevator can be effectively used for rescue operations.

  Further, in the conventional technology, even when there is no landing call and there are only one evacuee in the car, when the car call to the evacuation floor is registered, the vehicle is operated directly to the evacuation floor. For this reason, depending on the timing at which landing calls are registered on the non-fire floor and the number of evacuees, the elevator can be operated back and forth between the non-fire floor and the evacuation floor with a small number of people, so efficient rescue operations cannot be performed. There is a problem.

JP 2003-276964 A

  Therefore, it is an object of the present invention to provide an elevator evacuation operation system that can efficiently and promptly rescue a person left in a building when a fire occurs.

  The elevator evacuation operation system according to the embodiment includes detection means, load detection means, and control means. The detection means is installed in a hall or hoistway on each floor and detects the occurrence of a fire. The load detection means detects a load higher than the allowable load range of the car in a normal state when a fire occurs. When the detection signal is supplied from the detection means, the control means causes more users than the normal number of passengers to get on the basis of the detection signal of the load detection means.

  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration in which an elevator is stopped at, for example, the top floor, and the configurations of other floors are substantially the same. Halls on each floor are provided with a hall call button device 1 and a fire detector 2 for detecting a fire in the building. A car 3 is waiting in the hoistway SFT. Further, an escape staircase FE is provided beside the hall.

  FIG. 2 is a cross section taken along line AA in FIG. 1 and shows the configuration of the car 3.

  A car operation panel 6 is provided in the car 3. This in-car operation panel 6 includes a destination floor registration button 4-1 for registering a car call, a door opening / closing button 4-2 for opening / closing the car door, and a door operation operation during fire rescue according to the present embodiment. The display / sound output unit 5-1 as a notification device indicating the mode and the display unit 5-2 indicating the remaining time until the elevator departs (moves).

  FIG. 3 shows the structure of the hole viewed from the direction of arrow B shown in FIG. The hall call button device 1 includes a hall call registration button 7, a display indicating the operation mode of the door operation during fire rescue according to the present embodiment, the voice output unit 8-1, and the remaining until the elevator starts (moves). It has a display unit 8-2 showing time.

  FIG. 4 shows the lower portion of the car 3 as seen from the direction of arrow C shown in FIG. A load detecting device 11 shown in FIG. 5 is provided at the lower portion of the car 3 and the lower beam 10. The car 3 is movable with respect to the lower beam 10, and the distance between the bottom of the car 3 and the lower beam 30 is changed according to the load of the car 3.

  FIG. 5 shows an example of the load detection device 11 viewed from the direction of the arrow D shown in FIG. On the back surface of the floor 9 of the car 3, for example, a switch WLS constituting the load detecting device 11 is provided. The lower beam 10 is provided with a pressing portion 12 that can press the operation element of the switch WLS. As will be described later, the load detection device 11 detects that the loaded load in the car is 130% at the time of fire rescue. That is, when the number of passengers in the car 3 increases and the car 3 descends, and the loaded load in the car 3 reaches 130%, the operator of the switch WLS comes into contact with the pressing portion 12 and the switch WLS is turned on.

  FIG. 6 shows an elevator operating apparatus according to the embodiment, and the same parts as those in FIGS. 1 to 5 are denoted by the same reference numerals.

  In FIG. 6, the control device 30 installed in the machine room includes an input / output unit 31, a control unit 32, and a motor control unit 33. The input / output unit 31 includes call registration signals output from hall call button devices 1-1 and 1-2 to 1-z provided on each floor, and fire detectors 2-1 and 2-2 provided on each floor. The fire detection signal output from ~ 2-z, the load detection device 11 provided below the car 3, and the position detection signal output from the pulse detector 35 described later are supplied. Each signal supplied to the input / output unit 31 is supplied to the control unit 32. The control unit 35 controls the operation of the entire elevator based on a signal supplied from the input / output unit 31, and performs operation control during normal times and operation control when a fire occurs. The output signal of the control unit 32 is supplied to the motor control unit 33, for example. For example, a motor 34 constituting a hoisting machine is connected to the motor control unit 33, and the motor 34 is driven by the motor control unit 33. The motor 34 is provided with a pulse detector 35 as a motor position detector, and a position detection signal output from the pulse detector 35 is supplied to the input / output unit 31.

  An opening / closing signal of a door (also referred to as a door) output from the control unit is supplied to a door control unit 36 provided in the car 3 via the input / output unit 31. The door control unit 36 controls the door motor 37 to open and close the door.

  In the above configuration, the operation control of the elevator will be described.

(Normal operation)
For example, call registration signals from the hall call button devices 1-1 and 1-2 to 1 -z are supplied to the control unit 32 via the input / output unit 31. The control unit 32 determines the response floor and the landing floor based on the call registration signal. The control unit 33 supplies the determination result to the motor control unit 33, and the motor control unit 33 drives and controls the motor 34 of the hoisting machine. As a result, the car is moved to the response floor.

  Next, when the car approaches the landing floor, the position signal detected by the pulse detector 35 and the preset floor position are compared by the control unit 32, and when these differences reach a certain distance. The moving speed of the car is reduced, and the car is landed on the response floor and stopped. At this time, a signal for door opening / closing operation is sent from the control unit 32 through the input / output unit 31 to the door control unit 36 provided on the car 3. Based on this signal, the door control unit 36 controls the rotation speed of the door motor to open and close the door.

(Operation in case of fire)
Next, with reference to FIG. 7 thru | or FIG. 13, the operation | movement at the time of fire outbreak is demonstrated.

  FIG. 7 shows the operation of the control unit 32 when a fire occurs, and FIGS. 8 to 12 show a sequence of relays constituting the control unit 32. In FIG. 7 and FIGS. 8 to 12, the same parts are denoted by the same reference numerals. Further, in FIGS. 8 to 12, the switches of the relays are in a steady state.

  When a fire occurs, a signal indicating fire detection is generated from any of the fire detectors 2-1, 2-2 to 2 -z provided on each hall side, and is transmitted via the input / output unit 31 of the control device 30. Is supplied to the controller 32 (S1). That is, when any of the fire detectors 2-1, 2-2 to 2-z installed on each floor is activated when a fire occurs, the fire detectors 2-1, 2-2 to 2-z shown in FIG. The corresponding switch among the fire switches R1-1, R1-2 to R1-z provided corresponding to is turned on. Then, the relay FIRE connected to these switches R1-1, R1-2 to R1-z is turned on.

  Next, the allowable range of the loaded load is changed (S2). When the relay FIRE is turned on, when the load reaches 110% with respect to a standard load (not shown), the operation of closing the elevator door is canceled and is invalidated. When the relay FIRE is turned on, the normally closed contact FIRE shown in FIG. 9 is turned off, and the normally open contact FIRE is turned on.

  Next, it is determined whether or not there is a car call (S3-1). If there is no car call and there is a hall call (S3-2), the car is driven to the response floor, landing, stopped, The door is opened (S4). That is, when the hall call is detected, the relay H is turned on, and the contact H is turned on. Since the landing relay EL shown in FIG. 9 is a relay that is turned on when the landing conditions of the landing relay EL other than the present embodiment are satisfied, the operating condition is omitted, but is currently landing. Is on. Therefore, the relay DOS that starts opening the door is turned on.

  When the relay DOS is turned on, the contact DOS is turned on. As described above, since the normally closed contact is turned off and the normally open contact is turned on when the relay FIRE is turned on, the door opening shortening timer is turned on (S5). For this reason, when the fire detector is operating, the time for keeping the door open is switched to the door opening shortening timer. The door opening shortening timer is set shorter than the normal door opening timer. For this reason, the time for holding the door in the open state is shorter than the normal time, and the door closes earlier. Therefore, when the fire detector is operating, the door is opened once in response to the car call and hall call, but the door opening time is shorter than usual.

  FIG. 12 shows an example of the door opening shortening timer and the time of the door opening timer. The time of the door opening timer is set to 30 seconds, for example, while the time of the door opening shortening timer is set to 10 seconds, for example.

  In a state where the door is opened and the door opening shortening timer is turned on, an evacuee as a user can get in the car. When the loaded load in the car is 110% or less, the normally closed contact FWR shown in FIG. 10 is on. Since the contact STM driven by the door opening shortening timer is on, the door opening relay DO is also on. For this reason, since the normally open contact DO is on, the door motor 37 is driven in the direction of the arrow shown by the solid line in the figure, and the door is held open (S7). At this time, the elevator is in the time priority mode.

  Further, since the normally closed contact DO of the relay DO is turned off, the relay DC for closing the door is turned off. Therefore, even when the door close button is operated, the door is kept open. That is, the operation of the door close button is invalidated (S8).

  In the time priority mode in which the load in the car is 110% or less, when the time set in the door opening shortening timer has elapsed, the contact STM shown in FIG. 10 is turned off (S8-1). For this reason, the relay DO is turned off, and the normally open contact DO and the normally closed contact DO are in the state shown in FIG. Therefore, the relay DC is turned on, and the normally open contact DC is turned on. For this reason, the door motor 37 is driven in the direction of the arrow indicated by the broken line in the drawing, and the door is closed (S11). Thereafter, the car is moved to the evacuation floor, and is landed and stopped (S12).

  In addition, when the door opening shortening timer shown in step S5 is on, there are many evacuees and the door remains open even when the load in the car reaches 110%. That is, in the event of a fire, when the loaded load reaches 110%, the switch 1WS shown in FIG. 8 is turned on and the relay 1WR is turned on. For this reason, the contact 1WR of the relay 1WR is turned on, and the relay FWR is turned on. Then, the normally closed contact FWR shown in FIG. 10 is turned off, and the relay DO is turned off while the door opening shortening timer is on (S6). Therefore, the elevator is in the load priority mode. In the load priority mode, the load capacity of the car is between 110% and 130% or less as an allowable range.

  When the relay DO is turned off in the load priority mode, the normally closed contact DO is turned on and the normally open contact DO is turned off. For this reason, the door closing relay DC is turned on. For this reason, the door motor 37 is driven in the direction of the arrow indicated by the broken line in the drawing, and the door is closed (S11). Thereafter, the car is moved to the evacuation floor, and is landed and stopped (S12).

  In the load priority mode, when the loaded load exceeds 130%, the switch WLS is activated, the relay WR is turned on, and the normally closed contact WR is turned off. For this reason, the relay FWR is turned off and the normally closed contact FWR is turned on. Thereafter, when the door opening shortening timer is turned off, the contact STM is turned off, and the door opening relay DO is turned off. For this reason, the door closing relay DC is turned on. Therefore, even when there are a large number of evacuees whose car load exceeds 130%, it is possible to evacuate quickly by operating the car.

  In addition, the load priority mode in which the car load is 110% to 130% or less is activated (S6). In this case, the contacts FIRE and FWR shown in FIG. 11 and the contact LTM of the door open timer are on. For this reason, the relay LD for load priority mode is turned on. For this reason, the contact LD of the relay LD is turned on, and the display output unit 41 and the input terminal 2 of the audio output unit 42 are enabled. For this reason, a signal indicating "overload" and a "signal indicating the remaining time until departure" are output from the display output unit 41, and the display / audio output unit 5-1 in the car 3 shown in FIG. “Overloading” is lit on the display, and the time until departure (about 5 seconds) is displayed on the display section 5-2, for example, countdown. Further, a signal indicating “overload” is output from the audio output unit 42 to the display / audio output units 5-1 and 8-2, and an announcement is made in the car and in the hall. Therefore, it is possible to notify the evacuees in the car and in the hall that the elevator is starting (S9-1).

  In addition, when there is an evacuee on the hall side, the character “overload” is lit on the display output unit 41 on the hall side, so that the user in the hall has exceeded the allowable load. It can be recognized that the elevator moves to the evacuation floor. Therefore, users in the hall can evacuate using the evacuation stairs without waiting for the elevator.

  On the other hand, when the door opening shortening timer is on (S5), if the allowable load range of the car is 110% or less, the time priority mode is activated (S7). In this case, since the contact FIRE shown in FIG. 11 and the contact STM of the door opening shortening timer are turned on, the relay TM for the time priority mode is turned on and the contact TM is turned on. For this reason, the input terminal 3 of the display output part 41 and the audio | voice output part 42 is validated. Accordingly, a signal indicating “underloading” is output from the display output unit 41, and the display / audio output unit 5-1 in the car 3 shown in FIG. 2 and the table display / audio output unit 8- of the hall shown in FIG. The letter “underloading” is lit in 1. Further, the audio output unit 42 outputs a signal indicating that “the time mode is in operation because of insufficient load” to the display / audio output units 5-1, 8-1, It is announced as voice information in the hall and can be notified to the user (S10-1).

  In addition, when the time priority mode is activated, the characters “waiting” are lit on the display units 5-2 and 8-2 on the car side and the hall side. The time until departure (about 10 seconds) is notified by, for example, a countdown.

  In addition, the evacuee on the hall side can confirm the waiting time until the elevator reaches the evacuation floor without the load capacity exceeding the allowable range. For this reason, it is possible to accurately determine whether or not a rescue operation is possible, such as accurately determining a priority order such as evacuating a disabled person first, or searching for another refugee.

  Further, in a state where the door opening shortening timer is on, when the load is 110% or less, the door is opened in the time priority mode. In this state, when the door close button 4 in the car shown in FIG. 11 is pressed (S8), the display output unit 41 and the input terminal 1 of the audio output unit 42 are validated. In this case, the display output unit 41 outputs a signal indicating “underloading”, and the audio output unit 42 outputs a signal “underloading, door close invalid, time priority mode is in operation”. Is done. For this reason, since the information is displayed and announced to the user by the voice / display output units 5-1 and 8-1 in the car and the hall, the user presses the door close button 4. It can be recognized that the operation is invalid.

  In step S3-1, when the load is 110% or less and there is a car call, the control is transferred to step S11, the elevator closes the door, and landing / stops on the evacuation floor (S12).

  FIG. 13 shows an example of display on the display output unit 41 (sound output unit 42) provided in the car and hall in the building at the time of the occurrence of a fire. In FIG. 13, the uppermost floor is, for example, the 10th floor, the evacuation floor is, for example, the first floor, and the 10th floor is the fire occurrence floor. Further, for example, the ninth floor, the fifth floor, and the third floor are set as intermediate floors.

  In the event of a fire, if it is detected that a fire has occurred on the 10th floor by a signal from the fire detector, the destination of the car is displayed as the 10th floor on the 10th floor as the fire occurrence floor. For this reason, the evacuees on the 10th floor can confirm that the car is heading toward the 10th floor.

  In addition, the display output unit on the other floor in the building displays and announces the detection signal of the fire detector and the result determined based on safety on each floor. In other words, the display output sections on the 9th, 6th and 5th floors of the middle floor indicate that the car is on the 6th floor, and the display output section on the 3rd floor indicates that the car is on the 1st floor. . Therefore, it can be seen that the 9th and 5th floor evacuees can get on the car by going to the 6th floor by the stairs, and the 3rd floor evacuees are 1 on the stairs because the car is on the 1st floor. You can see that you should evacuate to the floor.

  In this way, by guiding the evacuees, the evacuees on the intermediate floor and the lower floor in the building can be divided into a certain number of people and guided to a specific floor. For this reason, it is possible to optimize the number of people who can get on the car, and it is possible to evacuate the evacuee quickly and effectively using the elevator.

  According to the above embodiment, when a fire occurs, the allowable range of the load capacity of the car is set to be larger than the normal time. For this reason, a large number of evacuees can be evacuated effectively in the event of a fire.

  Also, in the event of a fire, the door opening time is shorter than normal. For this reason, when the load of the car is less than the allowable range, the car can be immediately closed and the car can be moved to the evacuation floor. Therefore, since the car can be operated quickly, it is possible to evacuate and rescue the evacuees at high speed.

  In addition, the display output unit 41 displays whether or not the car's load has been exceeded and whether or not the car can still be ridden. For this reason, when the car moves to the evacuation floor due to the car's payload exceeding the allowable range, it has the effect of encouraging the evacuees who remain on the hall side to use the evacuation stairs instead of the elevator. I can expect. Therefore, it is possible to select an appropriate evacuation means (elevator or evacuation stairs) without panicking during an evacuation.

  In addition, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, 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, constituent elements over different embodiments may be appropriately combined.
