Description

  The present invention relates to an elevator group management control device and method, and more particularly to an elevator group management control device and method having a function for evacuation operation in a fire.

  In recent years, it has been studied to use an elevator for evacuation at the time of fire in a high-rise building as the fire prevention performance of the building is improved. However, during a fire, unlike in normal times, it is assumed that a large number of elevator users will rush to the landings on each landing floor. It is necessary to transport a large number of elevator users to a safe place efficiently with a group management elevator control device that controls multiple cars. However, in the case of group management control during normal times, there is a tendency to give priority to overall efficiency. Because it is strong, it is difficult to say that the optimal car distribution is possible from the viewpoint of serviceability to the urgent section of the building.

  In order to avoid such a situation, Patent Document 1 discloses an apparatus that performs dedicated group management control specialized for evacuation operation in the event of a fire. The fire escape evacuation apparatus disclosed in Patent Document 1 divides a landing floor to be serviced into a plurality of service zones, and has a plurality of passenger cars serving each service zone from the entrance floor. When the fire detector installed in the station detects a fire, each car stops at the nearest floor. In the event of a fire, it is determined that evacuation operation is not possible for a car that services a zone that includes a fire floor, and the operation after the stop of the nearest floor is stopped, and for a car that services a zone that does not include a fire floor Evacuation driving availability judgment means for judging that evacuation operation is possible, rescue floor setting means for setting a rescue floor according to the landing floor where a fire has occurred for the car judged to be evacuation driving, and judgment that evacuation operation is possible And an evacuation operation command means for providing evacuation support for the residents of the building by reciprocating the transported car between the entrance floor serving as an evacuation floor and the rescue floor. According to such a configuration, the residents in the zone that does not include the fire floor can be efficiently evacuated to the evacuation floor, but the residents in the zone that includes the fire floor must move to another zone. For example, there is a problem that an elevator cannot evacuate and a car serving a zone including a fire floor cannot be used for evacuating residents.

  In the evacuation operation that has been proposed in the past, including the invention disclosed in Patent Document 1, the piston operation between the fire floor and the evacuation floor for the purpose of increasing the number of vehicles allocated to the vicinity of the fire floor, The building has been divided into zones and the number of vehicles dispatched to the zone near the fire floor has been increased. However, such a control method clearly distinguishes between the landing floor where the car is dispatched and the landing floor where the car is not dispatched, which raises a great deal of anxiety for those who are on the floor where the car is difficult to dispatch. Panic is likely. In order to alleviate such a situation, a voice announcement device or a guidance device is provided at the elevator platform, etc., and a method such as guiding the evacuation person to the landing floor where the car can be used is taken. Considering the installation cost of such a device, it is not necessarily a good measure, and there is a problem that it cannot be applied to a building where such a device cannot be installed.

  Hereinafter, exemplary embodiments of the present invention will be described as an example with reference to the drawings as appropriate.

(First embodiment)
FIG. 1 is a diagram for explaining a configuration example of an elevator group management control device 100 according to an embodiment of the present invention. In FIG. 1, in order to clarify the configuration of the group management control device 100, a part of the elevator system that is the control target is also shown. The controlled object of the elevator group management control device 100 is a plurality of elevator systems. In the drawing, three systems of elevator systems are shown as an example. However, the elevator group management control device according to the present invention is not limited to the control of the three systems of elevator systems, and can execute control of any number of systems of elevator systems. An elevator system of three systems, system A, system B, and system C shown in FIG. 1, is a car 102A, 102B, and 102C, and a lifting device (not shown) that lifts and lowers the cars 102A, 102B, and 102C, respectively. And elevator control devices 104A, 104B and 104C for controlling the operations of the passenger cars 102A, 102B and 102C and the corresponding lifting devices, respectively.

Each of the cars 102A, 102B, and 102C is provided with a car call button (not shown) for the passenger of the car to designate a destination floor, and a load that does not exceed the load weight of the car. Detection devices 106A, 106B and 106C are provided, respectively. A landing call button such as landing call buttons 108A, 108B for a person who desires to board the car to call the cars 102A, 102B, and 102C is provided at the landing floors of the elevators. The landing call signals issued from the landing call buttons 108A, 108B, etc. are transmitted to the group management control device 100 and registered by the call registration device 110 of the group management control device 100. A car management signal is also provided in each of the cars 102A, 102B, and 102C, and is issued from a car call button (not shown) for a passenger of the car to designate a destination floor. 100 and registered by the call registration device 110 of the group management control device 100. During normal times when no fire has occurred, the allocation control device 112 included in the group management control device 100 operates based on the overall efficiency and the like based on the landing call and car call registered by the call registration device 110. As is done, the elevator control devices 104A, 104B and 104C are instructed on which floor to respond and the most appropriate car 102A, 102B or 102C is assigned to the registered landing call. In other words, the allocation control device 112, in a normal time when no disaster occurs, in accordance with the conventional elevator group management control method known to those skilled in the art, the cars 102A, 102B and 102C taking into account the overall transportation efficiency. Carry out the dispatch. For example, the time required for the cars 102A, 102B, and 102C to arrive for a call issued from the landing is calculated, and dispatch is performed so that the average value is minimized. However, when a fire breaks out, the allocation method in normal times does not necessarily prioritize dispatch to a high-risk floor such as a floor near the fire floor. Therefore, in the event of a fire, it is necessary to change the allocation control method from the normal method so that the car can be quickly dispatched to a high-risk floor.

  Fire detectors such as fire detectors 114A and 114B are provided on the landing floors of the elevator, and these fire detectors such as fire detectors 114A and 114B give a signal indicating whether or not a fire has been detected. , To the operation pattern switching device 116 and the fire occurrence floor identification device 118 of the group management control device 100.

  An outline of an example of the operation of the group management control device 100 when a fire occurs will be described with reference to FIG. FIG. 2 is a flowchart showing an outline of an example of the operation of the group management control device 100 according to this embodiment. In normal times, the group management control device 100 performs control in the normal mode (S202). When a fire occurs, the operation pattern switching device 116 receives a fire occurrence signal output from a fire detector such as the fire detector 114A or 114B, and changes the operation pattern from the normal evacuation operation to the allocation control device 112. A command to switch to evacuation operation in case of fire is transmitted (S206). At this time, the driving pattern switching device 116 transmits to the call registration device 110 a destination floor designation signal from the cars 102A, 102B and 102C, that is, a command for prohibiting registration of the car call (S208). . As a result, during the evacuation operation, the passenger of the passenger car cannot designate the destination floor, and the passenger's getting-off floor is selected by the getting-off suitable floor selecting device 122 as will be described later. When the allocation control device 112 receives the switching command signal from the driving pattern switching device 116, the group management control device 100 shifts to the control mode during evacuation driving. The fire occurrence signal output from the fire detector 114A or 114B or the like is also received by the fire occurrence floor identification device 118, and the fire occurrence floor is identified (S210). The evacuation priority determination device 120 is based on the fire occurrence floor identified by the fire occurrence floor identification device 118, the top and bottom floors of the building, the position of the evacuation floor unique to the building, etc. The evacuation priority of each landing floor to which the car is sent for rescue of the person waiting for boarding, that is, the car responds is determined (S212). The evacuation priority of each landing floor is determined regardless of whether or not the landing call is registered. A method for determining the evacuation priority of each landing floor will be described in detail later with reference to FIG. The landing call signals issued from the landing call buttons such as the landing call buttons 108A and 108B are received by the call registration device 110, and the landing floor corresponding to the received landing call signal is in the order in which the landing call signals are received. It is registered and stored in the landing call list (S214). The call registration device 110 is always in a state of receiving a landing call signal, and when the landing call signal is received, it is additionally registered in the landing call list. The evacuation priority of each landing floor determined by the evacuation priority determination device 120 and the data of the landing call list registered by the call registration device 110 are transmitted to the assignment control device 112. The allocation control device 112 is a landing call issuing floor to which a car 102A, 102B or 102C (hereinafter may be referred to as 102 (X)) is not allocated and is registered in the landing call list. The landing floor with the highest evacuation priority is selected as a landing call issuing floor to respond (S216). Next, the assignment control device 112 selects the car 102 (X) to be assigned to the landing call issue floor selected in S216 to be answered (S218). When all the cars 102 (X) have already been assigned, the process waits until the assignment of any car 102 (X) is released. The assignment control device 112 instructs the elevator control device 104 (X) corresponding to the selected car 102 (X) to respond to the landing call issuing floor to which the car 102 (X) is assigned (S220). . That is, the car 102 (X) is instructed to travel toward the landing call issuing floor that should be responded selected in S216. In accordance with this instruction, the car 102 (X) travels toward the assigned landing call issuing floor. Data relating to the evacuation priority of each landing floor determined by the evacuation priority determination apparatus 120 is transmitted to the getting-off suitable floor selection apparatus 122. The getting-off floor selection device 122 selects the getting-off floor suitable for getting off the person boarding at the landing call issuing floor selected in S216 (S222). The getting-off floor selection device 122 responds to the landing call to which the car 102 (X) is assigned, and after the person waiting for the car on the selected landing call issuing floor gets on the car 102 (X) However, the elevator control device 104 (X) that controls the car 102 (X) is instructed to travel toward the landing floor (getting-off compatible floor) where the passenger selected in S222 gets off ( S224). Thereafter, the process returns to S216, and the car 102 (X) that responds in order to the registered landing call having a high evacuation priority is selected based on the data of the evacuation priority and the landing call list. The process is repeated.

  Next, a method for determining the evacuation priority of each landing floor by the evacuation priority determination device 120 in the group management control device 100 will be described. As described above, the group management control device 100 includes the fire occurrence floor identification device 118 that identifies the location information of the fire occurrence floor from the fire occurrence signal transmitted from the fire detector such as the fire detector 114A or 114B. Based on the fire occurrence floor identified by the fire occurrence floor identification device 118, the evacuation floor held in the group management control device 100, and the position information of the end floor, the evacuation priority determination device 120 performs each landing. Determine floor evacuation priority.

  The evacuation priority of each landing floor is appropriately set so as to be higher than that of the floor to be rescued immediately. Hereinafter, an example of evacuation priority determination in the present embodiment will be described. First, the evacuation priority of each landing floor is expressed by two parameters, “category” and “level”. First, the evacuation priority of each landing floor is determined by the level of the category, and the evacuation priority of the landing floor of the group having the higher category is set higher than the evacuation priority of the floor of the group having the lower category. For landing floors belonging to the same category, a higher evacuation priority is set for a higher floor landing floor.

  The category indicates what state or attribute the landing floor corresponds to among the states or attributes such as an evacuation floor or a fire occurrence floor. As the status or attribute of the landing floor, “end floor” having the attribute of the top floor or the bottom floor, “evacuation floor” having the attribute of being set in the building and capable of exiting the building in the event of a disaster, fire There are four types: “fire occurrence floors” that are identified by the occurrence floor identification device 118 and have a fire, and “other” floors that do not fall under any of these. If the status or attribute of a certain landing floor falls into more than one of the four types, it will be given priority in the order of “Fire floor”> “Evacuation floor”> “End floor”> “Other”. Specify the floor status. The category value is determined as follows, for example. First, since the “fire occurrence floor” is the most dangerous, it is set to the highest category 5. Since the “evacuation floor” is considered to be the safest, the lowest category 0 is set. The “Other” floors are ranked in descending order of risk. “Other” floors that are sandwiched between the “fire-breaking floor” and other “fire-flooring floors” and that do not have an evacuation floor between them are classified as Category 4 “Other” floors where there is no evacuation floor between the cages and the nearest end floor are set as category 3. In addition, the floor between the fire occurrence floor and the nearest evacuation floor is set as Category 2, and the evacuation floor between which there is no fire occurrence floor and another evacuation floor, or the evacuation floor and the nearest end floor The floor between the floor and the nearest end floor is defined as category 1.

  Next, an example of how to determine the level will be described with reference to FIG. Although the method of obtaining the level differs depending on the category to which the landing floor belongs, it can be basically determined by the positional relationship between the “fire occurrence floor” or “evacuation floor” and the landing floor. Where α is the total floor height of all floors of the building, X is the distance to the nearest fire floor, Y is the distance from the evacuation floor to the fire floor, and the distance from the landing floor to the nearest evacuation floor The distance in each category is determined as follows, where the distance is Z. First, the fire occurrence floor of category 5, the level of this floor is α. The level of the category 0 evacuation floor is 0. The level of the floors in Category 4 and Category 3 is α-X. This means that the priority decreases as the distance from the fire floor increases. In addition, the level of the category 2 landing floor sandwiched between the fire occurrence floor and the nearest evacuation floor is based on the ratio of the distance X to the nearest fire occurrence floor relative to the distance Y from the evacuation floor to the fire occurrence floor. Is reduced from α. For example, the level of the category 2 landing floor is α · (1−X / Y). The level of the category 1 landing floor is the distance Z from the landing floor to the nearest evacuation floor.

  A specific example of the evacuation priority determined according to the category and level setting method described above as an example is shown in FIG. Here, the building is 30 stories, 3 floors below ground and 25 floors above ground, and the height of each landing floor is 3 [m]. The evacuation floors are 1F and 9F. Usually, the evacuation floor is set to a floor that allows residents to go outside the building. FIG. 4 assumes a case where a fire has occurred at 4F and 19F. In this case, 4F and 19F which are fire occurrence floors are category 5, and 1F and 9F which are evacuation floors are 0. 20F to 24F sandwiched between the fire occurrence floor 19F and the uppermost end floor 25F and the end floor 25F of this section are category 3. Furthermore, 2F and 3F sandwiched between the fire occurrence floor 4F and the evacuation floor 1F, 5F to 8F sandwiched between the fire occurrence floor 4F and the evacuation floor 9F, and 10F to 18F sandwiched between the fire occurrence floor 19F and the evacuation floor 9F Is category 2. Finally, B1 to B4 sandwiched between the evacuation floor 1F and the end floor B5 which is the lowest floor, and the end floor B5 are defined as category 1.

  The level is also determined by the method shown in FIG. The total value α of the floor height of the building is 3.0 [m] × 30 floors = 90. Therefore, the levels of 4F and 19F, which are fire floors, are 90. In addition, the levels of 1F and 9F, which are evacuation floors, are 0. The level of floors belonging to category 3 is determined by the distance from the fire floor. For example, the level of 23F is determined as α−X = 90 [m] −3.0 [m] × 4th floor = 78 using the distance X from the nearest fire occurrence floor 19F. The level of the floor belonging to category 2 is obtained by α · (1−X / Y), for example, using the distance Y from the evacuation floor to the fire occurrence floor. For example, the level of 12F which is a floor belonging to category 2 is X = 3.0 [m] × 7 floor = 21, Y = 3.0 [m] × 10 floor = 30, and 90 × (1-21 / 30) = 27 (rounded up if fractional). Further, the level of the landing floor belonging to category 1 is obtained from the distance Z to the nearest evacuation floor, for example, the level of B4 is 3.0 [m] × 4 = 12.

  Next, an example of a method for assigning the car 102 (X) to the issued landing call according to the determined evacuation priority will be described. As a premise, in the present embodiment, the allocation control device 112 in the group management control device 100 has a downward call even if the signal transmitted from the landing call buttons such as the landing call buttons 108A and 108B is an upward call. Even so, the same way of thinking is used to allocate the car to the landing floor that issued the landing call. This is because the car 102 (X) responding to the landing call is automatically directed to the exit suitable floor selected by the method described later, and the direction of the landing call itself is not related. In addition, in the present embodiment, a description will be given of a case in which only one landing call calling floor is allocated to each landing car and only one landing car is allocated to one landing calling floor. In other embodiments described later, different allocation methods are applied.

  Hereinafter, a specific example of the elevator group management control device 100 that controls the three passenger cars 102A, 102B, and 102C via the corresponding elevator control devices 104A, 104B, and 104C will be described. However, even if the number of cars to be controlled increases, the same concept can be applied. The group management control device 100 records, in order, floors from which landing calls are issued as a landing call list in the call registration device 110 provided therein. The call registration device 110 holds the allocation state of each landing call in the landing call list. The assigned state indicates whether or not a car is assigned to each landing call, and, if assigned, which system car 102 (X) is assigned. As an example, FIG. 5A shows a hall call list at a certain time point.

  For example, the allocation state corresponding to the landing call from 9F recorded as registration order 1 in the landing call list is “not yet”. This indicates that no car is assigned to the landing call from 9F recorded as the registration order 1. In addition, the allocation state corresponding to the landing call from 23F recorded as the registration order 4 is “A”. This is because the car 102A of the system A out of the three cars issues the call. Indicates that it is assigned to a floor. The same applies to the allocation states “B” and “C”, which indicates that the B machines and C cars are allocated to the 22F and 20F, respectively, which are landing call issue floors. The evacuation priority of the landing call issuing floors 23F, 22F, and 20F to which the car is assigned is higher than the evacuation priority of other landing floors registered in the landing call list shown in FIG. . Newly received landing calls are added to the end of the landing call list. Conversely, when the assigned car 102 (X) arrives at the landing call issuing floor to which the car should respond and departs with the passenger on board, the calling information on the floor registered in the landing call list is displayed. Is deleted, and the registration order of other landing calls is advanced. The call registration device 110 always keeps the latest information on the floor where the landing call is registered and its assigned state in the landing call list while repeating the updating in this way.

  The assignment control device 112 assigns which car to which landing call issue floor based on the information registered in the landing call list of the call registration device 110 and the priority of the landing floor determined by the evacuation priority determination device 120. Decide what to allocate. First, the selection of the landing floor to which the car is allocated is determined according to the evacuation priority of the landing call calling floor registered in the landing call list. The specific example of the evacuation priority determined by this embodiment has been described above with reference to FIG. In the present embodiment, the evacuation priority of the landing floor has a category and a level, but a floor having a higher category is first selected. When floors of the same category are registered, floors with higher levels are selected. When a plurality of landing floors of the same category and of the same level are registered, the flooring floor that is registered earlier (the floor that is registered at the top of the landing call list) is selected. Assume that the contents of the boarding call list are as shown in FIG. 5B and there is still a car 102B that can be assigned. In this case, the landing floor having the highest evacuation priority among the floors with the allocation status “unknown” in the landing call list shown in FIG. 5B is the category 3 based on the evacuation priority shown in FIG. Level 24 F. Therefore, 24F is selected as the landing call issue floor to which the response should be made. As described above, the allocation control device 112 selects a landing call issue floor to be responded to according to the evacuation priority.

  When the landing call issuing floor to be responded is selected, next, the assignment control device 112 selects the car 102 (X) to respond to the selected landing floor. As a selection criterion, for example, a method of selecting the car 102 (X) that takes the shortest time to arrive at the selected landing floor is generally used. However, when the contents of the landing call list are in the state shown in FIG. 5B and there are three cars, the only car that can be assigned remains the car 102B of the system B. The car 102B is assigned as a car responding to 24F. As a result, the hall call list changes from the state shown in FIG. 5B to the state shown in FIG.

  Thereafter, as long as there is a car that can be assigned, the assignment control device 112 continues to assign the car 102 (X) until there is no more car that can be assigned. When the assignment is executed for all the cars 102 (X) managed by the group management control device 100, the assignment of the subsequent cars is temporarily stopped, and the process waits until an assignable car 102 (X) appears. In this way, instead of the allocation method considering only the overall efficiency executed in the normal group management control, the floors to be responded are selected in the order according to the evacuation priority described above.

Next, a method for selecting the destination floor of the car 102 (X) by the getting-off suitable floor selection device 122 will be described. In this specification, “target floor” means the landing floor where passengers who use the elevator are lowered from the car, and “descending floor” is the purpose of passengers evacuating using the elevator in the event of a fire. It means a floor that is safe and has a low risk level. In this embodiment, the getting-off suitable floor selection device 122 selects a route that can be operated from the landing calling floor to which the car (X) responds more safely among one or more evacuation floors unique to the building. The evacuation floor corresponding to the route is selected as a suitable exit floor. Therefore, in the present embodiment, the destination floor is any evacuation floor. As a route that can be safely operated toward the evacuation floor, for example, a route that does not have a fire occurrence floor may be selected in the middle of the operation route. There is also a method of selecting using the evacuation priority exemplified in FIG. Now, the car 102 (X) the allocated landing call issued floor located in R, the S _P position of Chakuyukakai corresponding to evacuation floor _P, and categories that define the evacuation priority Chakuyukakai F C (F), the level is L (F). At this time, using the values shown in FIG. 4, a value of the risk of root R → S _P of S (P) calculated from equation (1). Similarly, the landing floor position corresponding to the evacuation floor Q from the position R of the landing floor that issued the landing call

The S (Q) is a sum of products of up to S _Q, was calculated using the same formula as formula (1), the value of S (Q) and the risk of root R → S _Q. Thus, for each evacuation floor, each evacuation floor is based on the parameters that define the evacuation priority of each landing floor along which the car on the way from the landing calling floor to which the car (X) responds to the evacuation floor. The risk level is calculated and the route with the smallest value is selected as the safe route. That is, the getting-off suitable floor selection device 122 obtains the risk level when traveling from the landing floor to which the car (X) responds to each evacuation floor based on the category and level that are parameters defining the evacuation priority. The route with the lowest risk is selected as the safe route, and the evacuation floor corresponding to the selected route is selected as the exit suitable floor. For example, when the building is in the state shown in FIG. 4, the risk of the route from 5F to each evacuation floor is obtained as follows. From the values shown in FIG. 4, the risk when the evacuation floor 9F is the destination floor is 2 × 54 + 2 × 36 + 2 × 18 = 216, and the risk when the evacuation floor 1F is the destination floor is 5 × 90 + 2 ×. 60 + 2 × 30 = 630. Accordingly, it is determined that the evacuation floor 9F as the destination floor is less dangerous and safer, and the evacuation operation is performed with the passenger on this floor. The risk of a route depends greatly on whether or not the route includes a fire floor.

  The getting-off suitable floor selected by the getting-off suitable floor selecting device 122 is transmitted via the assignment control device 112 to the elevator control device (X) that controls the car (X).

  As is clear from the above description, according to the present embodiment, it is possible to cause the car to respond quickly to a dangerous landing floor that urgently needs to be evacuated in the event of a fire, compared to normal group management control. Become. In addition, a person who evacuates from a dangerous landing floor using an elevator can get off the destination floor through a safer route. The evacuation priority and the selected getting-off compatible floor are updated each time the situation such as the position of the fire occurrence floor changes. The update can be easily performed by the fire occurrence floor identification device 118 monitoring changes in signals from fire detectors such as the fire detectors 114A and 114B.

(Second Embodiment)
The getting-off floor selection device 122 according to the present embodiment is selected from the landing call calling floor to which the car 102 (X) responds after selecting the getting-off floor by the method described in the description of the first embodiment. A landing floor that is determined not to be an evacuation floor but is safe according to a predetermined standard is selected as a destination floor under a predetermined condition in the middle of a route to a floor suitable for getting off. For example, the landing suitable floor selecting device 122 selects a landing floor having an evacuation priority category of 2 or less as a destination floor during evacuation operation, not an evacuation floor. In yet another example, a landing floor belonging to a category of category 2 or lower and having a level of 10 or lower is set as a safe destination floor during evacuation operation. When this standard is set, it is assumed that the car (X) responds to 16F in the state of FIG. 4 showing a specific example of the evacuation priority. In this case, the getting-off floor selection device 122 selects the evacuation floor 9F as the getting-off floor. The landing floors along the route from 16F to 9F are all Category 2, and among these flooring floors, the flooring floors having a level of 10 or less are 10F and satisfy the above-mentioned criteria. Therefore, in this case, the getting-off suitable floor selecting device 122 selects 10F as the destination floor of the car (X), and the car (X) travels from 16F to 10F.

  According to this embodiment, by selecting a landing floor that satisfies the criteria other than the evacuation floor as the destination floor, the concentration of people in the evacuation floor landing and the congestion of the landing are alleviated, and a new car arrives. Evacuation can be efficiently performed by avoiding a situation in which the passenger cannot easily get off, and by shortening the traveling time of the car during evacuation operation and responding quickly to other landing calls. Whether or not the landing on the evacuation floor is congested can be determined by installing a human sensor at the landing and transmitting a signal from the human sensor to the group management control device 100, or arrived at the evacuation floor. The group management control device 100 may determine based on a criterion such as “the door opening time of the car 102 (X) has reached or exceeded a specified value (30 seconds or the like)”.

  However, the above destination floor selection method in the present embodiment is executed only when the type of landing call issued from the landing call button is a general (normal) call that is not a wheelchair call. If the type of boarding call is a wheelchair call, even if the landing floor is determined to be a safe landing floor, if the passenger gets off the landing floor, the wheelchair user will This is because the use of stairs will be forced for those who have difficulty walking. Accordingly, when the landing call is a wheelchair call, the evacuation floor selected by the evacuation floor selection method by the getting-off suitable floor selection device 122 described in the first embodiment is selected as the destination floor of the car 102 (X). . In the present embodiment, the type of landing call is registered in the landing call list of the call registration device 110 that receives the landing call, and the type of landing call is determined by the getting-off floor selection device 122 referring to the landing call list. recognize.

(Third embodiment)
In this embodiment, when a car is assigned by the assignment control device 112 described in the description of the first embodiment, a plurality of cars are allowed to be assigned to one landing call. Judgment of whether or not a landing call is allowed to be assigned to multiple vehicles is determined by, for example, the height of the evacuation priority category of the landing floor where the landing call is issued, and the landing call belongs to a category higher than the predetermined category. Permits allocation of multiple cars for landing calls issued from the floor. Here, the value of the category, which is a parameter that defines the evacuation priority of the landing floor from which the landing call is issued, is acquired from the evacuation priority determination device 120 that determines the evacuation priority of the landing floor. For example, a case is assumed in which allocation of two cars is permitted for a landing call issued from a landing floor belonging to a category of category 3 or higher. When a new landing call is received, if the category to which the landing floor from which the new landing call is issued belongs to category 3 or more, the landing call from the landing floor is added to the landing call list of the call registration device 110. Register. As described above, the allocation control device 112 refers to the landing call list of the call registration device 110 to determine the allocation of the car, so that the registration is performed by registering a plurality of landing calls in the landing call list. Allocation control is executed so that the number of cars in accordance with the number of boarding calls being made is dispatched.

  According to this embodiment, it is possible to evacuate a person who is waiting for an elevator for evacuation on the landing floor having a high evacuation priority earlier.

(Fourth embodiment)
The evacuation priority determination device 120 according to the present embodiment includes not only the state or attribute of each landing floor and the positional relationship between the landing floors, but also load detection devices 106A provided in each of the cars 102A, 102B, and 102C. By considering the load information acquired from 106B and 106C, the evacuation priority determined first during the evacuation operation is changed. However, the evacuation priority category is not changed and only the evacuation priority level is changed so that the priority relationship in the allocation control does not collapse significantly. The method for determining the evacuation priority at the start of the evacuation operation is as described in the first embodiment. The evacuation priority determination device 120 arrives at the landing floor where the car 102 (X) that responded to the landing call in response to an instruction from the assignment control device 112 issued the landing call while proceeding with the evacuation driving control after starting the evacuation operation. Then, the information from the load detection device 106 (X), for example, the loading rate, is received when the passenger gets on and the elevator door is closed. The evacuation priority determination apparatus 120 increases or decreases the level of evacuation priority based on the received load information such as the loading rate. Although the method for increasing or decreasing the evacuation priority level is not unique, for example, when the loading rate detected by the load detection device 106 (X) of the car 102 (X) is less than 80%, the car 102 If the evacuation priority level of the landing floor to which (X) responds is reduced by 10% from the initially determined value and the loading rate is 80% or more, the floor 102 to which the car 102 (X) responds Increase the evacuation priority level by 10% from the initially determined value.

  According to the present embodiment, for the landing floor where the number of people waiting to board the elevator has decreased, priority is given to dispatching the car 102 (X) until some people gather and evacuate. It is possible to raise the allocation priority of the car 102 (X) to another landing floor in which a large number of power persons still remain.

(Fifth embodiment)
In the description related to the first embodiment described above, when the assignment control device 112 selects the car 102 (X) to respond to the selected one landing floor, the car 102 (X) selects the car 102 (X). A case has been described in which the car 102 (X) is not assigned unless it responds to the one landing floor, arrives at the destination floor, and lowers the passenger. The assignment control device 112 in the present embodiment selects the car 102 (X) that should respond to the selected one landing floor, and responds to the one landing floor in which the car 102 (X) is selected. On the landing floor, when the elevator user gets on the car 102 (X) and the loading rate at the time when the elevator door is closed is less than a predetermined value, the car 102 (X) is put on another car. Let the floor also respond. That is, when the loading rate of the car 102 (X) when the person waiting on the selected landing floor is boarding is less than a predetermined value, the passenger is kept on the board, The car 102 (X) is made to respond to another landing floor. Here, the allocation control device 112 acquires the loading rate of the car 102 (X) based on information from the load detection device 106 (X) provided in the car 102 (X). For example, when the car 102 (X) responds to one selected floor and the elevator user gets on the car 102 (X) on the floor and closes the elevator door, For example, when it is less than 50%, the assignment control device 112 regards the car 102 (X) as a state in which additional assignment is possible, and selects an appropriate one from other landing call issuing floors registered in the landing call list. Select a landing floor and make additional allocations for other selected landing calls.

  In addition, if the loading rate of the car 102 (X) after the elevator user boarded in response to another additionally assigned landing call calling floor is still less than the predetermined value, the same shall be applied. In addition, it is also possible to select a landing floor that can be additionally allocated to other landing calls.

  As is clear from the above description, according to the present embodiment, another landing call calling floor is maintained while the passenger is on the car with a sufficient loading ratio in which the evacuating passenger is not riding much. By responding to, it becomes possible to evacuate the residents efficiently.

  However, since it is necessary to prevent the car 102 (X) from moving to a dangerous landing floor by adding an assignment to another landing call calling floor, it can be assigned when adding an assignment to another landing calling floor. It is necessary to set restrictions on the appropriate landing call. For example, in the case of a category belonging to the same category as the first assigned landing floor, “Only respond to landing floors belonging to the category below the first assigned landing floor category” It is only possible to respond to landing floors that are lower than the level of the first assigned landing floor, or "cannot be reached without moving in the opposite direction to the getting-off suitable floor selected by the getting-out suitable floor selecting device 122" For the landing floor, a condition that “response is possible only within the second floor” is added. In addition, when moving from the first assigned landing floor to another landing floor in the same manner as the calculation of the travel route risk performed by the getting-off suitable floor selecting device 122 in the description relating to the first embodiment, It is also possible to add a condition that the degree of danger of the travel route is obtained and that the response is possible only when the obtained degree of danger is equal to or less than a predetermined value.

  By providing such a restriction, it is possible to select a floor that can be additionally allocated without exposing the passengers in the car to a dangerous state.

(Sixth embodiment)
The allocation control device 112 according to the present embodiment has an evacuation priority higher than any of the landing call calling floors to which these cars respond even when all the cars 102 (X) are allocated. When a landing call from a higher landing floor is newly registered, a new landing car call assigned to respond to the landing call issuing floor with a lower evacuation priority is newly registered. Change the assignment to respond to the departure floor. At this time, the assigned state of the landing call issue floor having a low evacuation priority that has been selected so that the car has responded is changed to unassigned.

  For example, the landing call is registered as shown in the landing call list shown in FIG. 5A, and the cars 102A, 102B, and 102C are assigned to respond to 23F, 22F, and 20F, respectively. Assume a case. In this state, all three cars controlled by the group management control device 100 are assigned. In this state, it is assumed that a landing call is newly issued from 21F and registered. Comparing the evacuation priority of 20F, 22F, and 23F of the landing call registration landing floors to which the car has already been assigned and the new registration floor 21F, the priority is 20F> 21F (new)> 22F> 23F. . In this case, the car 102A registered so as to respond to 23F having a low evacuation priority is assigned to the new registration floor 21F, and the assignment state of 23F is changed to “not yet”. In some cases, the car 102B registered to respond to 22F is assigned to a new registration floor 21F, and the assignment state of 22F is changed to “not yet”.

  According to the present embodiment, it is possible to assign a car to a landing call having a high evacuation priority on a case-by-case basis.

  However, in any case, if the assignment is changed to a floor with a high evacuation priority, there may be waste. For example, when the car is about to land on the floor already allocated, it is considered more efficient to respond to the floor allocated already. Therefore, the allocation can be changed only when the car 102 (X) has not reached the deceleration start position in order to stop at the allocation floor to which it responds. Further, even if the car 102 (X) heading to the landing floor with the lower evacuation priority, which is the target of the assignment change, needs to reverse the direction in order to respond to a new landing call, the assignment change is not performed.

(Seventh embodiment)
The assignment control device 112 according to the present embodiment, when all the cars 102 have been assigned, has a landing call floor where the assignment state registered in the landing call list is “not yet”. Is notified that it takes time until the car 102 arrives. The form of notification is matched with the type of equipment (not shown) installed at the landing, for example, a voice announcement device or a message display device. The platform equipment that has received the notification sends the content of the notification to the platform. There are various methods for sending a notification that it takes time to arrive at the car 102 to the landing. For example, a method of sending an announcement "Please wait for a while" to the landing using a voice announcement device (not shown), There are a method of displaying a message having the same content on a message display device (not shown), or a method of using these voice announcements together with a message display.

  According to this embodiment, it becomes possible to accurately convey the situation to residents who are thinking of evacuating by an elevator, and residents who are considering evacuating by an elevator use the elevator. Recognizing that evacuation will take some time, you can get a good idea of whether you should wait for the elevator or evacuate using stairs.

  While various embodiments have been described above, the group management control device according to the present invention is implemented as an embedded system that operates according to embedded software using hardware such as a microcomputer (MPU), ROM, and RAM, for example. It is also possible to implement by dedicated hardware such as a gate array, FPGA or cell array.

  As described above, in the embodiment of the present invention, the evacuation priority is determined for each landing floor based on the information on the fire occurrence floor obtained from the building side by the fire occurrence signal of the fire detector or the like. In the group management assignment algorithm during normal operation, the car is assigned based on the evacuation priority for each landing floor. As a result, it becomes possible to execute more flexible car allocation in accordance with the evacuation priority for each landing floor in consideration of the risk level. The embodiment of the present invention is an evacuation operation control at the time of fire that is executed by adding other information to the group management allocation control at the time of normal operation, and can give the algorithm more flexibility than the conventional technology. Is possible. In addition, unlike the execution of a piston operation between a specific floor and an evacuation floor of a building, an apparatus for announcing an evacuation route to an in-building person is unnecessary, and the installation cost can be suppressed.
