Abstract

The application provides an elevator control system and an elevator control method. The problem is to alleviate the uneasiness of passengers caused by the stop of a car for which the reason for the passengers is unknown. The solution is that a car operation management part (101) temporarily stops the target car (130a) when an operation blocking condition occurs, wherein the operation blocking condition is that the traveling of the target car (130a) which is a traveling car is blocked due to the influence of other cars (130 b). When the target car (130a) temporarily stops, the notification unit (102) outputs notification information including a meaning indicating a normal stop using an information presentation device (131) provided in the target car (130 a).

Disclosure of Invention

Problems to be solved by the invention

Generally, in a multi-car elevator, cars are sometimes stopped at a place other than a landing as a destination in order to avoid collision of the cars with each other and the like. In this case, the passengers of the car may feel uneasy without knowing the cause of the stop of the car.

In the technique described in patent document 1, it is assumed that the traveling of the car is prohibited, and no consideration is given to stopping the traveling car. In addition, in the technique described in patent document 2, since collision between the cars is avoided by changing the deceleration pattern of the cars, no consideration is given to stopping the traveling cars. Therefore, the techniques described in patent documents 1 and 2 cannot alleviate the uneasiness of passengers due to the stop of the car, which is unknown to the passengers.

An object of the present disclosure is to provide an elevator control system and an elevator control method that can alleviate a sense of unease of passengers due to stop of a car that is unknown to the passengers.

Means for solving the problems

An elevator control system according to an aspect of the present disclosure is an elevator control system that controls a multi-car elevator in which a plurality of cars provided with an information presentation device run in the same hoistway, and includes: a car operation management unit that temporarily stops a target car when an operation-inhibited situation occurs in which travel of the target car, which is the running car, is inhibited by an influence of another car; and a notification unit that outputs notification information including a meaning indicating a normal stop using an information presentation device provided in the target car when the target car temporarily stops.

Effects of the invention

According to the present invention, it is possible to alleviate the feeling of uneasiness of passengers due to the stop of the car, which is unknown to the passengers.

Detailed Description

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

(embodiment 1)

Fig. 1 is a diagram showing an example of a configuration of an elevator system according to embodiment 1 of the present disclosure. The elevator system shown in fig. 1 has an elevator control system 100, hall call buttons 110 and an elevator 120.

The elevator control system 100 is a control device that controls an elevator 120. The elevator control system 100 may also control multiple elevators 120 as shown.

The hall call button 110 is a button for making a hall call to the car of the elevator 120, and is provided at each landing of the elevator 120, for example.

The elevator 120 is a multi-car elevator in which a plurality of cars (car) 130 are disposed in the same hoistway. In the example of the figure, the elevator 120 is shown with 3 cars 130 out of m cars 130. Each car 130 is provided with an information presentation device 131 for outputting and presenting various information to passengers.

The information presentation device 131 may be, for example, a voice output device that outputs voice such as a speaker, a display device that displays images such as a display and a signboard, or a combination thereof.

Further, although not shown, each car 130 further includes: a button part including a car call button for making a car call to the car, a door opening button for opening the door of the car, a door closing button for closing the door of the car, and the like; and a mass measurement sensor for detecting the presence or absence of passengers and the number of passengers in each car 130.

The elevator control system 100 includes a car operation management unit 101 and a notification unit 102.

The car operation management unit 101 manages the operation of the elevator 120. For example, the car operation management unit 101 monitors a call (car call and hall call) being made, a car 130 corresponding to the call, the position of each car 130 in the elevator 120, the traveling state (speed, acceleration, etc.) of each car, the presence or absence of passengers in each car, and the like, as the operation state of the elevator, and controls the traveling of each car 130 based on the monitored state.

Further, the car operation management unit 101 determines whether or not an operation-inhibited situation has occurred based on the operation situation, the operation-inhibited situation being: a situation in which the travel of the target car, which is a traveling car, among the cars 130 disposed in the same hoistway in the elevator 120 is hindered by the influence of the other cars. The car operation management unit 101 temporarily stops the target car when an operation-hindered situation occurs. At this time, for example, the car travel management section 101 may temporarily stop the target car at the landing and open the door of the target car.

In the present embodiment, the operation-inhibited situation is a situation that is expected to be closer than a predetermined distance between the target car and another car without temporarily stopping the target car. The operation-inhibited situation includes a situation in which the predetermined distance is zero, that is, a situation in which the target car is expected to collide with another car. The predetermined distance may be the same as or different from the safety distance d described later in embodiment 3.

The notification unit 102 outputs various kinds of information to the information presentation device 131 of the car 130 used by the passengers of the car 130. Specifically, when the target car temporarily stops, the notification unit 102 outputs notification information including a message indicating that the stop of the car is a normal stop, using the information presentation device 131 of the target car. The notification unit 102 may output the notification information only when there is a passenger in the target car. In addition, when the door is opened when the target car is temporarily stopped, the notification information may further include an indication that the door is normally opened.

Fig. 2 is a diagram showing a specific example of the elevator 120. In the elevator 120 shown in fig. 2, 2

cars

130a and 130b are installed as the cars 130 in 1 hoistway 200. The

cars

130a and 130b are connected to different ropes (not shown) and can travel independently of each other. In addition, the

cars

130a and 130b cannot be simultaneously present at the same position in the vertical direction of the hoistway 200. That is, the

cars

130a and 130b cannot overtake each other. In the example of the figure, the car 130a is located further below than the car 130 b.

The service floors at the landings of the car range from 1 floor to 8 floors. The number of cars 130 and the number of floors as the number of landings are not limited to this example. In addition, a space for accommodating the car 130b and allowing the car 130a to travel to the 8 th floor may be provided in the upper part of the hoistway 200, or a space for accommodating the car 130a and allowing the car 130b to travel to the 1 st floor may be provided in the lower part of the hoistway 200.

Fig. 3 to 5 are diagrams for explaining the operation of the elevator system according to the present embodiment. Hereinafter, the elevator 120 is an elevator 120 shown in fig. 2.

Fig. 3 is a diagram for explaining the operation of the elevator system in a case where one of the 2

cars

130a and 130b is raised and the other is stopped. In the drawings of the present disclosure, good symbols indicate service floors designated by car calls, and Δ symbols indicate service floors called by hall calls.

Fig. 3 (a) shows a situation in which the car 130a with passengers thereon is traveling in the ascending direction from floor 1 to floor 6 in response to a car call, and the car 130b is stopped at floor 5. In this case, the car travel management unit 101 sets the car 130a as the target car 130 a. In addition, the car 130b may or may not have passengers.

In the situation of fig. 3 (a), since the car 130b stops at the 5 th floor, the car 130b blocks the travel of the target car 130a, and the car cannot travel to the target 6 th floor. Therefore, the car operation management unit 101 determines that the operation-inhibited situation has occurred, and temporarily stops the target car 130a below 5 floors (3 floors in the example of the drawing) as shown in fig. 3 b. In this case, the call to the car at the floor 3 and the call to the hall at the floor 3 are not made, and the stop of the target car 130a is not expected for the passenger of the target car 130a, and the reason is not considered to be clear. Therefore, there is a fear that the passenger feels an uncomfortable feeling.

In the present embodiment, if the target car 130a temporarily stops, the notification unit 102 outputs notification information including information indicating that the car normally stops, using the information presentation device 131 of the target car 130 a. This can alleviate the feeling of uneasiness of the passenger.

Fig. 4 and 5 are diagrams for explaining the operation of the elevator system when both of the 2

cars

130a and 130b travel. In this case, the car operation management unit 101 selects one of the

cars

130a and 130b as the target car, and if an operation-obstructing situation occurs, stops the target car and continues the travel of the other cars.

As a method of selecting the car to be selected, a method of preferentially selecting a car having a passenger among the

cars

130a and 130b as the car to be selected may be mentioned. In this case, when both the

cars

130a and 130b have passengers or when both the

cars

130a and 130b have no passengers, the car operation management section 101 selects the target car according to, for example, the traveling conditions of the

cars

130a and 130 b. For example, the car travel management unit 101 may select, as the target car, one of the

cars

130a and 130b that is expected to take a relatively short time until the target landing is reached, or may select, as the target car, one that has traveled for a relatively long time. Hereinafter, the car 130a is referred to as a target car 130 a.

Fig. 4 is a diagram for explaining the operation of the elevator system when both of the 2

cars

130a and 130b travel in the same direction (in this case, the ascending direction).

Fig. 4 (a) shows a situation in which the target car 130a on which the passenger is riding is traveling in the ascending direction from floor 1 toward floor 5 in response to a car call to floor 5, and the car 130b is traveling in the ascending direction near floor 4. The speed of the target car 130a is set to be higher than the speed of the car 130b, and the target car 130a collides with the car 130b before reaching the 5 th floor if the target car does not stop. That is, an operation-hindering condition occurs.

In this case, as shown in fig. 4 (b), the car travel management unit 101 temporarily stops the target car 130a before the collision with the car 130b (3 floors in the example of the drawing). Then, the notification unit 102 outputs notification information including a message indicating a normal stop using the information presentation device 131 of the target car 130a, thereby alleviating the discomfort of the passenger.

Fig. 5 is a diagram for explaining the operation of the elevator system in a case where 2

cars

130a and 130b travel in different directions from each other.

Fig. 5 (a) shows a situation in which the target car 130a on which the passenger is riding is traveling in the ascending direction from floor 1 to floor 6 in response to a car call to floor 6, and the car 130b is traveling in the descending direction from floor 7 to floor 5 in response to a hall call to floor 5. In addition, the target car 130a collides with the car 130b before reaching the 6 th floor if the car is not stopped. That is, an operation-hindering condition occurs.

In this case, as shown in fig. 5 (b), the car travel management unit 101 temporarily stops the target car 130a at a position before 5 floors (3 floors in the example of the drawing). Then, the notification unit 102 outputs notification information including a message indicating a normal stop using the information presentation device 131 of the target car 130a, thereby alleviating the discomfort of the passenger.

As described above, according to the present embodiment, the car operation managing unit 101 temporarily stops the target car 130a when an operation blocking situation occurs in which the travel of the target car 130a, which is a traveling car, is blocked by the influence of the other car 130 b. When the target car 130a temporarily stops, the notification unit 102 outputs notification information including a message indicating that the car normally stops, using the information presentation device 131 provided in the target car 130 a. Therefore, the feeling of uneasiness of the passenger due to the stop of the car, which is unknown to the passenger, can be alleviated.

In the present embodiment, the operation-inhibited situation is a situation in which it is expected that the target car 130a and the other car 130b are closer than a predetermined distance. In this case, the target car 130a can be appropriately temporarily stopped.

In the present embodiment, since the notification unit 102 outputs the notification information when there is a passenger in the car 130a to be temporarily stopped, unnecessary operations (output of the notification information) can be suppressed.

In the present embodiment, when the temporarily stopped target car 130a is opened, the notification unit 102 outputs notification information that also includes an indication that the opening of the target car 130a is a normal opening. Therefore, the feeling of uneasiness of the passenger due to the door opening of the car, which is unknown to the passenger, can be alleviated.

(embodiment 2)

In the present embodiment, an example of an opposed-car balancing multi-car elevator in which 2 or more cars are used and car rings connected to the same rope are formed so as to serve as counterweights is described as an elevator system. Hereinafter, the configuration and operation different from those of embodiment 1 will be mainly described.

Fig. 6 is a diagram showing an example of the configuration of an elevator system according to the present embodiment. The elevator system shown in fig. 6 is different from the elevator system of embodiment 1 shown in fig. 1 in that: a car ring 140 including a plurality of cars 130 is formed in the elevator 120; and an elevator control system further comprises a loop car management unit 103 and a car loop stop mode determination unit 104.

There may also be multiple car rings 140 in 1 elevator. The number of the cars 130 included in the car ring 140 is not particularly limited as long as the balance of the cars 130 can be achieved, but is an even number, more specifically, 2.

Fig. 7 is a diagram showing an example of an elevator 120 according to the present embodiment.

The elevator 120 shown in fig. 7 is a circulating type opposed-car balance type multi-car elevator, and service floors are from 1 floor to 8 floors. The number of floors is not limited to this example.

The elevator 120 has an endless hoistway. Specifically, the hoistway includes a hoistway 201 dedicated to the ascending direction in which the car 130 travels in the ascending direction, and a hoistway 202 dedicated to the descending direction in which the car 130 travels in the descending direction. The hoistway includes a direction reversing space 203 connected to the upper sides of the

hoistways

201 and 202, and a direction reversing space 204 connected to the lower sides of the

hoistways

201 and 202. The direction reversing space 203 is a hoistway for reversing the traveling direction of the car 130 traveling in the ascending direction in the hoistway 201 and traveling in the hoistway 202. The direction reversing space 204 is a hoistway for reversing the traveling direction of the car 130 traveling in the descending direction in the hoistway 202 and traveling in the hoistway 201.

The elevator 120 is provided with 4 cars 130a to 130d as the cars 130. The

cars

130a and 130b constitute a car loop 140a connected by the same rope so as to serve as counterweights, and the

cars

130c and 130d constitute a car loop 140b connected by the same rope so as to serve as counterweights. The number of cars 130 and the number of car rings are not limited to this example. Fig. 7 (a) shows the entire structure of the elevator 120 including the car rings 140a and 140b, fig. 7 (b) shows the structure of the car ring 140a, and fig. 7 (c) shows the structure of the car ring 140 b.

In the elevator 120, the cars 130a to 130d cannot travel in the same direction at the same position in the vertical direction of the hoistway at the same time, but can travel in different directions at the same time. Since the cars 130 included in the same car ring 140 are connected by ropes, if any of the cars 130 stops, the other cars 130 included in the same car ring 140 also stop. Therefore, the state in which the other cars 130 included in the same car ring 140 are stopped in a certain car 130 becomes a running-blocked state in which the running is blocked by the influence of the other cars.

The elevator 120 of the present embodiment is not limited to the circulating type as long as it is an opposed-car balanced multi-car elevator. For example, the

hoistways

201 and 202 may be configured such that the movement of the car in the ascending direction and the descending direction is possible in each of the

hoistways

201 and 202 without limiting the running direction of the car to one direction. In this case, the direction reversal space 203 and the direction reversal space 204 below may not be used, or may not be provided.

The explanation returns to fig. 6. The ring car management unit 103 holds ring car information 111 for identifying the car 130 included in the car ring 140 for each car ring 140.

When the car travel management unit 101 stops the target car, which is the running car 130, the car loop stop mode determination unit 104 determines whether or not the car travel management unit 101 temporarily stops the target car 130 due to a travel-hindered situation, based on the loop car information 111 held by the loop car management unit 103.

When the target car 130 is temporarily stopped, the notification unit 102 outputs notification information including information indicating that the car is normally stopped, using the information presentation device 131 of the target car 130, as in embodiment 1.

Next, the operation of the elevator system in the present embodiment will be described. In the following operation, the number of car rings is set to 1 for simplicity of explanation.

Fig. 8 is a diagram showing a circulation type opposed-car balance multi-car elevator in which the number of car rings is 1, and is the same as the configuration shown in fig. 7 (a) except for the configuration of the car ring 140 b.

Fig. 9 is a diagram for explaining an operation of the elevator system according to the present embodiment.

Fig. 9 (a) shows a situation in which the car 130a with passengers thereon is traveling in the hoistway 201 toward 6 floors in the ascending direction in response to a car call, and the car 130b is traveling in the hoistway 202 toward 6 floors in the descending direction in response to a hall call in the descending direction of 6 floors.

In the situation of fig. 9 (a), the car 130b arrives at the destination landing at 6 floors earlier than the car 130a, and the car 130a stops at 3 floors as shown in fig. 9 (b). In this case, the car 130a stops together with the car 130b, and therefore cannot travel to the 6 th floor of the destination landing.

In this case, the car loop stop mode determination unit 104 determines that the car 130a has an operation-inhibited situation, as will be described later in fig. 10. Then, the notification unit 102 outputs notification information including information indicating a normal stop using the information presentation device 131 of the car 130a, as in embodiment 1. In this case, the car 130a becomes the target car.

Fig. 10 is a flowchart for explaining the operation of the car ring stop mode determination unit 104.

First, in step S101, if any 1 or more of the cars 130 in the traveling of the elevator 120 are stopped, the car loop stop mode determination unit 104 acquires the stopped car information on the stopped car 130 from the car travel management unit 101. The stop car information includes, for example: list information indicating a list of stopped cars 130, passenger information indicating the presence or absence of passengers in stopped cars 130, position information indicating the position of stopped cars, call information indicating a call being serviced by stopped cars 130, and the like.

In step S102, the car loop stop mode determination unit 104 selects one of the cars 130 indicated by the list information included in the stopped car information as the car a as the 1 st car.

In step S103, the car-ring stop mode determination unit 104 determines whether or not there is a passenger in the car a based on the passenger information included in the stopped car information. The car loop stop mode determination unit 104 proceeds to the process of step S104 when there is a passenger, and proceeds to the process of step S108 when there is no passenger.

In step S104, the car ring stop mode determination unit 104 determines, as the car B, another car 130 included in the same car ring 140 as the car a based on the ring car information 111 held by the ring car management unit 103.

In step S105, the car loop stop mode determination unit 104 determines whether the car B has stopped due to a call corresponding to the car B itself, based on the call information included in the stopped car information. The car loop stop mode determination unit 104 proceeds to the process of step S106 when the car B has stopped due to the call corresponding to the car B itself, and proceeds to the process of step S108 when the car B has not stopped due to the call corresponding to the car B itself.

In step S106, the car loop stop mode determination unit 104 determines whether the car a has stopped due to a call corresponding to the car a itself, based on the call information. The car loop stop mode determination unit 104 proceeds to the process of step S107 when the car a is not stopped by the call corresponding to the car a itself, and proceeds to the process of step S108 when the car a has stopped by the call corresponding to the car a itself.

In step S107, the car ring stop mode determination unit 104 determines that the operation-hindered situation has occurred in the car a, and that there is a passenger in the car a, and identifies the car a as the car to be notified (step S107).

In step S108, the car ring stop mode determination unit 104 determines whether or not all the cars 130 indicated in the list information have been selected as the car a. When all the cars 130 have not been selected, the car ring stop mode determination unit 104 returns to the process of step S102, selects another car 130 as the car a, and ends the process when all the cars 130 have been selected.

When the car ring stop mode determination unit 104 has finished the processing, the notification unit 102 outputs notification information using the information presentation device 131 of the car 130 when there is the car 130 identified as the car to be notified.

According to the present embodiment, in the elevator 120 having the car ring 140 in which 2 or more cars 130 are connected to the same rope, particularly in the counter-car balance type multi-car elevator, since a state in which another car included in the same car ring 140 as the target car 130 is stopped is determined as a movement-obstructing state, it is possible to appropriately output the notification information.

(embodiment 3)

Here, a description will be given mainly of a configuration and an operation different from those of embodiment 2.

Fig. 11 is a diagram for explaining an operation of the elevator system according to the present embodiment. Fig. 11 shows a state in which the cars 130a to 130d are traveling in the elevator 120 having the same configuration as that shown in fig. 7 (a).

Fig. 11 (a) shows a situation in which the car 130a is traveling in the ascending direction in the hoistway 201 and the car 130b is traveling in the descending direction in the hoistway 202 in the car loop 140a in response to a hall call at 7 floors. In the car ring 140b, the car 130c is stopped at the 5 th floor of the hoistway 201, and the car 130d is stopped at the 5 th floor of the hoistway 202. The

cars

130a and 130b are assumed to be free of passengers. The

cars

130c and 130d may or may not have passengers. Here, the car 130a is set as the target car 130 a.

In the situation of fig. 11 (a), since the car 130c is stopping at 5 floors, the car 130a is obstructed from traveling by the car 130c and cannot travel to the intended 7 floors. Therefore, the car movement management unit 101 determines that the movement-obstructing situation has occurred, and temporarily stops the target car 130a below the 5 th floor as shown in fig. 11 (b). In this case, in the present embodiment, the car travel management unit 101 temporarily stops the target car 130a at a position where the other car 130 (that is, the nearest car 130c that is the closest in the traveling direction of the target car 130a) that causes the occurrence of the travel-hindered situation is separated from the target car 130a by a predetermined safety distance d or more. In the example of fig. 11 (b), the car travel management unit 101 temporarily stops the nearest car 130c at a position where the distance between the car 130c and the target car 130a is a predetermined safety distance d.

The safety distance d is for example a fixed value. The safe distance d may be a value corresponding to the speed of the target car 130 a. For example, the safety distance d may be set to be longer as the speed of the target car 130a (for example, the speed when it is determined that the target car 130a is temporarily stopped, the maximum speed, or the like) is higher. The safety distance d may be a value corresponding to the operating condition or the time zone of the elevator 140. For example, the safety distance d may be set to be shorter as the number of passengers in the target car 130a increases, or the safety distance d may be set to be shorter than in other time periods when a time period in which a number of passengers is expected increases.

As described above, according to the present embodiment, when the operation-hindered situation occurs, the target car 130a is temporarily stopped at a position where the distance between the target car 130a and the nearest car 130c is equal to or greater than the safety distance d, and therefore, the safety of the elevator 120 can be further ensured.

(embodiment 4)

Here, a description will be given mainly of a configuration and an operation different from those of embodiment 1.

In the present embodiment, an example will be described in which, in the elevator 120 described in embodiment 1, the car travel management unit 101 temporarily stops the target car at a position separated from the nearest car by a safety distance d or more. In the present embodiment, the safe distance d changes according to the traveling state of the nearest car.

Fig. 12 is a diagram for explaining the operation of the elevator system according to the present embodiment. Fig. 12 shows a state in which the car 130a is the target car and the car 130b is the nearest car, and an operation-hindered situation occurs, and the target car 130a is temporarily stopped.

Fig. 12 (a) shows an example in which the nearest car 130b stops, fig. 12 (b) shows an example in which the nearest car 130b travels in the same direction as the target car 130a, and fig. 12 (c) shows an example in which the nearest car 130b travels in the opposite direction to the target car 130 a. The safety distance d is the shortest in the example of fig. 12 (b), the longest in the example of fig. 12 (c), and the distance therebetween in the example of fig. 12 (a).

In the present embodiment, the target car 130a is assumed to have passengers. In this case, the car travel management unit 101 temporarily stops the target car 130a at a landing (service floor) closest to the nearest car 130b among landings (service floors) at which the distance between the target car 130a and the nearest car 130b is equal to or greater than the safety distance d, and opens the door of the target car 130 a.

According to the present embodiment, since the safety distance d changes according to the traveling state of the nearest car 130b, the target car 130a can be caused to travel to the vicinity of the destination hall while ensuring safety.

In the present embodiment, if there is a passenger in the target car 130a, the target car 130a is temporarily stopped at the landing, and therefore the passenger can travel from the target car 130a to a desired service floor or the like using stairs based on the judgment of the passenger, and the convenience of the passenger can be improved.

Here, a description will be given mainly of a configuration and an operation different from those of embodiment 4.

Fig. 13 is a diagram for explaining the operation of the elevator system according to the present embodiment. Fig. 13 shows a state in which the car 130a is the target car and the car 130b is the nearest car, and an operation-hindered situation occurs, and the target car 130a is temporarily stopped.

Fig. 13 (a) shows an example in which the nearest car 130b stops, fig. 13 (b) shows an example in which the nearest car 130b travels in the same direction as the target car 130a, and fig. 13(c) shows an example in which the nearest car 130b travels in the opposite direction to the target car 130 a. The safety distance d is the shortest in the example of fig. 13 (b), the longest in the example of fig. 13(c), and the distance therebetween in the example of fig. 13 (a).

In the present embodiment, unlike embodiment 4, the target car 130a is assumed to have no passengers. In this case, the car travel management unit 101 temporarily stops the target car 130a at a position separated from the nearest car 130b by a safety distance d. Further, the car travel management unit 101 does not open the door of the target car 130 a.

According to the present embodiment, the target car 130a can be driven to the vicinity of the destination hall while ensuring safety.

Fig. 14 is a diagram showing an example of the configuration of an elevator system according to the present embodiment. The elevator system shown in fig. 14 is different from the elevator system of embodiment 1 shown in fig. 1 in that the elevator control system 100 further includes a predicted stop time calculation unit 105.

For example, when the car operation management unit 101 temporarily stops the target car 130a as shown in fig. 3 (b), 4 (b), and 5 (b), the predicted stop time calculation unit 105 calculates a predicted stop time obtained by predicting a stop time at which the nearest car 130b stops at the target landing as a release prediction time until the operation-inhibited condition is released and the traveling of the target car 130a is resumed.

The notification unit 102 notifies not only the notification information but also the predicted stop time using the information presentation device 131 of the target car 130 a.

The method of calculating the predicted stop time is not particularly limited, and an example thereof will be described here.

If the number of passengers in the nearest car 130b is p, the number of passengers in the nearest car 130b is r, the time for 1 passenger to get off the car is a seconds, the time for 1 passenger to get on the car is b seconds, the door opening time is o seconds, and the door closing time is c seconds, the predicted stop time calculation unit 105 calculates the predicted stop time by the following equation (1), for example.

Predicted stopping time is the average number of people going off the elevator x a + min (average number of people going up the elevator (r- (p-average number of people going off the elevator)) × b + o + c · (1)

The average number of passengers and the average number of passengers are calculated in advance based on the actual work of the elevator 120, for example. The average number of passengers and the average number of passengers getting on/off the elevator may be an average value at all the landings, or may be calculated individually for each landing.

According to the present embodiment, since the predicted cancellation time until the operation-inhibited condition is cancelled is notified, it is possible to improve the convenience of the passenger.

(7 th embodiment)

Fig. 15 is a diagram showing an example of the configuration of an elevator system according to the present embodiment. The elevator system shown in fig. 15 is different from the elevator system of embodiment 1 shown in fig. 1 in that a door closing button disabling portion 106 is further provided in the elevator control system. Fig. 15 shows a door closing button 132 of each car 130, which is not shown in fig. 1.

In the present embodiment, when the operation-hindered situation occurs, the car operation managing section 101 temporarily stops the target car 130a at any one of the landings and opens the target car 130, as shown in fig. 3 (b), 4 (b), and 5 (b).

The door-closing button deactivation unit 106 deactivates the door-closing button 132 of the subject car 130a until the operation-blocked situation is released if the subject car 130a temporarily stops.

The notification unit 102 notifies not only the notification information but also the effect of disabling the door closing button 132 using the information presentation device 131 of the target car 130 a.

In the present embodiment, when the target car 130a cannot travel, it is possible to suppress the target car 130a from being closed and a person in a landing from being unable to ride on the target car, and therefore, convenience can be improved.

The embodiments of the present disclosure described above are examples for explaining the present disclosure, and it is not intended to limit the scope of the present disclosure to these embodiments. Those skilled in the art can implement the present disclosure in other various ways without departing from the scope of the present disclosure.
