Description

  The present invention relates to a traffic demand detection device that detects traffic demand of an elevator, an elevator group management device that collectively manages operations of a plurality of elevators, and an elevator system that includes the elevator group management device.

  In the elevator group management apparatus, there is a method of reducing congestion by determining the magnitude of traffic demand and increasing the number of elevators (number of vehicles dispatched) allocated to a landing floor call when the traffic demand is large.

  Such an elevator group management device is disclosed in, for example, Patent Literature 1 and Patent Literature 2. In Patent Document 1, there is a method of determining the number of recalls to the reference floor according to the total number of passengers for the past several minutes detected based on the load in the car or the statistical value of the number of passengers for each day and time zone. It is disclosed. Further, in Patent Document 2, when the number of waiting customers is detected by a camera provided at the hall, and it is determined that the current demand level is large compared with the statistical value of the same day of the week and time zone in the past, A method of assigning two or more elevators (cars) to a hall call is disclosed.

  The effect of increasing the number of dispatched vehicles varies depending on the size of passengers. In a situation where passengers exceeding the transport capacity are generated for a hall call in a certain direction on a certain floor and a queue is continuously generated at the hall (exceeding transport capacity), the hall call in that floor and the relevant direction By increasing the number of dispatched vehicles, the waiting time of waiting customers can be reduced and the queue can be relaxed. On the other hand, in a situation where passengers are generated at a scale that does not exceed the transport capacity for a hall call in a certain direction on a certain floor, if the number of dispatched vehicles is increased unnecessarily, an elevator with many passengers and passengers will get on too much As a result, the elevator arrival efficiency will increase and the elevator operation efficiency will not improve much, but rather the service of other floors will deteriorate. Therefore, it is possible to effectively reduce congestion by increasing the number of vehicles dispatched only while the situation of excess transport capacity occurs.

  However, since the elevator group management control device disclosed in Patent Document 1 determines the magnitude of traffic demand from the total number of passengers in the past several minutes, there is a problem that the scale of passenger generation cannot be determined. Moreover, since the elevator group management control device disclosed in Patent Document 2 detects the number of waiting passengers and determines the magnitude of traffic demand, it can detect the occurrence of a situation where the transport capacity is exceeded. Therefore, there is a problem that the installation of the camera for the camera is necessary, the cost for the camera installation is high, and the privacy protection by the camera shooting is lacking.

  The object of the present invention is to solve the above-mentioned problems, and even if no camera is installed, the traffic demand for the landing call in the registration direction on the registration floor is generated by passengers exceeding the transport capacity, and the queue is continuously queued at the landing Traffic that allows you to quickly detect that there is an excess of transportation capacity occurring at the time and increase the number of dispatched vehicles for landing calls in the registration direction on the registered floor only while the situation occurs To provide a demand detection device, an elevator group management device, and an elevator system.

  Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In the following embodiments, the same constituent elements are denoted by the same reference numerals, and description thereof is omitted.

First embodiment.
FIG. 1 is a block diagram showing a configuration of an elevator system 100 including an elevator group management device 30 and its peripheral components according to the first embodiment of the present invention. In FIG. 1, an elevator system 100 is suspended by a drive device 4 having a motor 2 and a drive sheave 3, and a main rope 5 hung on the drive sheave 3, and the inside of the hoistway is driven by the drive force of the motor 2. A car 7 that moves up and down, a counterweight 6, a scale device 8 that is mounted on the car 7 and detects a load in the car that is the weight of the car 7, and an elevator group that performs group management control of a plurality of cars 7. A management device 30 and a platform control device 1 that controls the operation of each car 7 are provided. In addition, the elevator system 100 controls a hall call button 12 for a passenger to call the car 7 for each floor and direction and a hall device connected to the hall call button 12 for each hall. 11. Here, the passenger registers the hall call by pressing the hall call button 12 for each floor and direction, and moves the car 7 to the registered floor (registered floor) and the registered direction (registered direction).

  In FIG. 1, the elevator group management device 30 detects a traffic demand detection device 20 that detects whether or not the traffic demand for a hall call in the registration floor and registration direction exceeds the transportation capacity, and the detection result from the traffic demand detection device 20. Based on the command signal from the vehicle allocation control unit 32, which is a vehicle allocation control unit that generates and outputs a command signal that commands the number of vehicles allocated to the hall call in the registration floor and the registration direction, Group management control which is a group management control means for generating a control signal for controlling each car 7 and outputting the control signal to the platform control device 1 to control the number of vehicles to be transferred to the hall call in the registration floor and registration direction Part 31. According to this configuration, whether or not the traffic demand for the landing call in the registration floor and the registration direction exceeds the transport capacity based on the temporal change in the car load detected by the weighing device 8 provided in the car 7 conventionally. The number of vehicles dispatched can be controlled based on the result, so no cameras are required, passengers exceeding the transport capacity are generated for landing calls in the registration floor and registration direction, and there is a queue at the landing It is possible to increase the number of dispatched vehicles only during the continuous occurrence, and effectively reduce congestion.

  Furthermore, the traffic demand detection device 20 includes a boarding status detection unit 21 that is a boarding status detection unit that detects information such as the time at which each passenger has entered the car 7 as boarding status information, and the boarding status. A storage unit 22 that stores information, and a demand detection unit 23 that is a demand detection unit that detects whether or not the traffic demand for a hall call in the registration floor and registration direction exceeds the transport capacity. According to this configuration, whether or not the traffic demand for the landing call in the registration floor and the registration direction exceeds the transport capacity based on the temporal change of the load in the car detected by the conventional weighing device 8 in the car. Because it is possible to detect, there is no need for a camera, and it is possible to quickly detect the situation where passengers exceeding the transport capacity are generated for the hall call for the registration floor and registration direction, and the queue is continuously generated at the hall It becomes possible to do.

  In FIG. 1, the platform control device 1 is connected to a drive device 4 provided for each car 7 and controls the drive device 4 based on a control signal from the group management control unit 31 to register the car 7 with a landing call. Move upwards or downwards toward the registered floor (registered floor). Further, the table control device 1 transmits the in-car load data detected by the scale device 8 mounted on each car 7 to the group management control unit 31.

  In FIG. 1, the boarding situation detection unit 21 receives the in-car load data transmitted from the group management control unit 31 and detects the boarding situation of the passenger in the car 7 based on the temporal change of the in-car load. Then, the detected data is output to the storage unit 22. Specifically, each time the car 7 arrives at the registration floor and departs, the time and load in the car at which each passenger was boarded between the arrival of the car 7 and the departure, and the elevator departure The car load at the time is detected as riding status information. According to this configuration, it is possible to obtain necessary and sufficient information based on the in-car load data in order to capture the characteristics of the boarding situation that is a base for detecting traffic demand.

  The memory | storage part 22 memorize | stores the data detected by the boarding condition detection part 21 according to each floor and direction as boarding condition information.

  The demand detection unit 23 detects whether or not the traffic demand for the hall call in the registration floor and the registration direction exceeds the transport capacity based on the boarding status information for each floor and direction stored in the storage unit 22. Is executed to determine whether or not the transportation capacity is exceeded, and the determined result is output to the vehicle allocation control unit 32. According to this configuration, every time the car 7 arrives at the registration floor, the excess of the transport capacity is detected based on whether or not the waiting situation is such that the waiting passengers ride in order until the inside of the car 7 becomes full. Therefore, it is possible to accurately detect whether the traffic demand for the hall call in the registration floor and the registration direction exceeds the transport capacity. Here, the situation where the traffic demand for the hall call in the registration floor and the registration direction exceeds the transport capacity is that passengers exceeding the transport capacity of the elevator system 100 are generated in the registration direction of the registration floor and queued at the landing. This refers to the situation where the problem occurs continuously.

  The vehicle allocation control unit 32 receives, from the demand detection unit 23, a result of determining whether or not the traffic demand for the hall call in the registration floor and the registration direction exceeds the transport capacity, and based on the determination result, the registration floor and the registration direction A command signal for instructing the number of vehicles to be assigned to the hall call is generated and the command signal is output to the group management control unit 31. For example, if the excess detection of the transport capacity is not detected in the previous detection process by the demand detection unit 23 and the excess of the transport capacity is detected in the detection process of this time, the dispatch control unit 32 assigns the landing floor to the registration floor and the registration direction. A command signal is generated to instruct the group management control unit 31 so that the number of dispatched vehicles is greater than the predetermined number of dispatched vehicles, and the command signal is output to the group management control unit 31. When the demand detection unit 23 detects the excess of the transport capacity in the previous detection process and does not detect the excess of the transport capacity in the current detection process, the dispatch control unit 32 determines the number of dispatched vehicles that has been determined in advance. A command signal for instructing the group management control unit 31 to be returned to is generated, and the command signal is output to the group management control unit 31. Furthermore, when the result of the detection process by the demand detection unit 23 is the same as the previous time and the current time, the vehicle allocation control unit 32 generates a command signal for instructing the group management control unit 31 so as not to change the number of vehicles allocated. Is output to the group management control unit 31.

  The hall control device 11 generates a signal indicating that there is a hall call in response to the fact that the passenger operates the hall call button 12 to register the floor and direction in which the car 7 is called, and outputs the signal. It transmits to the group management control part 31. The group management control unit 31 receives a signal indicating that there is a hall call from the hall control device 11 and, based on the received signal, the car 7 that is optimum for the hall call in the registration floor and the registration direction. And the car 7 is moved to the registration floor. Note that the number of cars 7 (number of vehicles dispatched) allocated to the hall call may be two or more, and the number of cars dispatched is determined in advance. The number of dispatched vehicles may be different depending on conditions such as days of the week and time zones. Further, the group management control unit 31 receives a command signal from the vehicle allocation control unit 32 and generates a control signal for controlling the number of vehicles allocated to the hall call in the registration floor and the registration direction based on the command signal. The control signal is transmitted to the table control device 1.

  Next, operation | movement of the elevator group management apparatus 30 which concerns on 1st Embodiment is demonstrated.

  FIG. 2 is a flowchart showing an elevator group management process executed by the elevator group management apparatus 30 of FIG. The elevator group management device 30 executes the process shown in the flowchart of FIG. 2 every time the car 7 arrives at the registration floor in response to the hall call in the registration floor and the registration direction. When each of the plurality of cars 7 arrives at a certain floor at the same time, the processing shown in the flowchart of FIG. 2 is executed on each car 7 in parallel. In FIG. 2, when the car 7 arrives at the registration floor and stops, the traffic demand detection device 20 is transmitted by the scale device 8 mounted on the car 7 transmitted from the table control device 1 via the group management control unit 31. The detected car load data is accumulated (step S101). The car load data is detected at regular time intervals, for example, at 100 millisecond intervals.

  In FIG. 2, in step S102, it is determined whether or not the car 7 of the elevator system 100 has started. If the car 7 has not yet started, the process returns to step S101, and the accumulation of the in-car load data is continued. When the car 7 departs, the boarding state detection unit 21 determines that the car 7 of the elevator system 100 arrives at the registration floor and departs based on the accumulated car load data, as will be described in detail later. A boarding situation detection process for detecting a boarding situation of a passenger who has boarded the car 7 is executed (step S103). In step S <b> 104, the storage unit 22 stores the boarding status information detected by the boarding status detection unit 21 in step S <b> 103 in the storage unit 22. For example, the current state detection process (the detection process before 0 times) is performed by the boarding state detection unit 21 from the time when the car 7 of the elevator system 100 stops on the registration floor to the time of departure of the elevator where the car 7 departs. In this case, all the boarding situation information detected up to a predetermined number of times of NA (here, NA is a natural number, the same shall apply hereinafter) is stored. At this time, when the boarding status information older than the predetermined number of times NA is stored in the storage unit 22 with respect to the registration direction of the registration floor, the oldest boarding status information may be sequentially deleted.

  In FIG. 2, in step S105, as will be described in detail later, the demand detection unit 23 responds to the hall call of the registration floor and the registration direction based on the boarding situation information of the registration floor and the registration direction stored in the storage unit 22. A detection determination process for excess transport capacity is performed to detect whether the traffic demand exceeds the transport capacity. Here, when the demand detection unit 23 determines that the traffic demand for the landing call in the registration floor and the registration direction exceeds the transport capacity, that is, the passenger queue is continuously generated in the registration floor where the landing call is registered. When the car 7 of the elevator system 100 arrives at the registration floor, the waiting passengers on the registration floor board the car 7 in order, and the car 7 becomes full. It is assumed that the situation in which the car 7 finishes and the car 7 departs is repeated. As the boarding situation at this time, passengers are smoothly boarded until the inside of the car 7 is somewhat congested, so the boarding interval between each passenger is short, and the load in the car at the time of departure from the elevator becomes a load indicating a full state Conceivable. For example, the load indicating the full state refers to a load when about 60% to 80% of passengers in the car 7 are in the car 7. Based on the above, a detection determination process for excess transport capacity is performed to detect whether the traffic demand for the registered floor and the registration direction exceeds the transport capacity.

  In FIG. 2, in step S <b> 106, the vehicle allocation control unit 32 determines a change in the number of vehicles allocated to the registration floor and registration direction hall calls based on the determination result by the demand detection unit 23 in step 105. If it is determined that the transport capacity has not been exceeded in the previous detection process by the demand detection unit 23 and it has been determined that the transport capacity has been exceeded in the current detection process, the dispatch control unit 32 determines the number of dispatched vehicles in advance. The group management control unit 31 is commanded to increase from the original number of dispatched vehicles (first dispatched number of vehicles). If it is determined that the transport capacity has been exceeded in the previous detection process by the demand detection unit 23 and it is determined that the transport capacity has not been exceeded in the current detection process, the dispatch control unit 32 determines the number of dispatched vehicles. The group management control unit 31 is instructed to return the number of dispatched vehicles that has been increased from the number of dispatched vehicles to the first number of dispatched vehicles. Furthermore, when the same determination result is obtained in the previous and current detection processes by the demand detection unit 23, the vehicle allocation control unit 32 instructs the group management control unit 31 not to change the vehicle allocation number as the current vehicle allocation number. Command.

  FIG. 3 is a flowchart showing in detail the boarding state detection process in step S103 in the flowchart of FIG. In step S201, each time point when the passenger has boarded is identified. Here, when there is a passenger in the car 7, the load in the car increases by the passenger's load. For example, when the load in the car increases by more than the load per passenger (for example, 65kg) The time when the passenger boarded.

  FIG. 4 is a graph showing the change in the load W in the car with respect to time T, which is detected by the scale device 8 mounted on each car 7 in FIG. In the example shown in FIG. 4, the car load W has increased from the car load w0 to the car load w1 at time t1, and the increase in the car load W (car load w1-car load w0). Is equal to or greater than the load per passenger (for example, 65 kg), the vehicle is identified as being in the car 7 at time t1. Further, at time t2, the car load W has increased from the car load w1 to the car load w2, and the increase in the car load W (car load w2-car load w1) per passenger If it is equal to or greater than the load (for example, 65 kg), it is identified as a time when the passenger has entered the car 7 even at time t2. Thereafter, in the same manner, all the points in time when passengers have entered the car 7 from the arrival of the elevator car 7 to the departure thereof are identified.

  In FIG. 3, in step S202, based on the identification result in step S201, the boarding interval between the passengers, that is, the time interval between each time point when the passenger boarded was calculated. Referring to the example shown in FIG. 4 described above, the time T when the first boarding is performed is the time t1, and the time T when the second boarding is performed is the time t2. Therefore, the boarding interval of the first passenger and the second passenger is (time t2−time t1). The time T at which the third boarding is performed is time t3, and the boarding interval between the second boarding passenger and the third boarding passenger is (time t3-time t2). Thereafter, the boarding intervals between the passengers are all calculated in the same manner.

  In FIG. 3, based on the identification result in step S201, the in-car load W at the time of each passenger's boarding and the in-car load W at the time of departure from the elevator are detected. With respect to the load W in the car at the time of each passenger's boarding, the load in the car excluding the increase due to each passenger's boarding at each time when the passenger boarded is detected (step S203). Referring to the example shown in FIG. 4 described above, the car load W increases from the car load w0 to the car load w1 at time t1 when the first boarding is performed. Therefore, the car load W at the time of boarding the first passenger is the car load w0. In addition, at time t2 when the second boarding is performed, the car load W increases from the car load w1 to the car load w2, and the car load W at the time of the second passenger's boarding is the car load. w1. In the example shown in FIG. 4, the car load W at the time of departure from the elevator is the car load Wdep.

  FIG. 5 is a flowchart showing in detail the detection determination process for excess transport capacity in step S105 in the flowchart of FIG. In step S301, 0 is substituted into a variable n (where 0 ≦ integer n ≦ NA). Here, the variable n indicates whether the demand detection unit 23 is currently processing the boarding status information n times before stored in the storage unit 22. Steps S302 to S306 are performed on the boarding status information from the current boarding status information stored in step S104 to a predetermined number of times before NA, and the traffic demand for the hall call in the registration floor and the registration direction determines the transport capacity. It is checked whether or not the boarding situation determined to be exceeded continues for a predetermined number of times NA.

  In FIG. 5, the demand detection unit 23 extracts the boarding situation information of the variable n times before stored in the storage unit 22 (step S <b> 302). Based on the extracted n-th previous boarding situation information, the demand detection unit 23 has predetermined first loading intervals between passengers whose car load W at the time of boarding is smaller than a predetermined first load WA. It is determined whether it is within the period TA (step S303). In step S303, if the boarding interval between all passengers whose car load W at the time of boarding is smaller than the predetermined first load WA is within the predetermined first period TA, the process proceeds to the next step S304. Further, if there is a boarding interval between passengers whose car load W at the time of boarding is smaller than a predetermined first load WA, and exceeds a predetermined first period TA, a hall call in the registration floor and in the registration direction. It is determined that the traffic demand for does not exceed the transport capacity (step S308). Here, the predetermined first load WA is, for example, a load slightly smaller than the load indicating the full state described above. Also, if the car 7 is congested to some extent by passengers, it will be difficult for the passengers to get in if the passengers in the car 7 are not packed, and the time required for the ride will be slightly longer. The first period TA is a time slightly longer than a standard time required for one passenger to get on, for example. The predetermined first load WA and the predetermined first period TA may be fixed values regardless of the specifications of the elevator system 100, or may be values determined according to the specifications of the elevator system 100. Further, the predetermined first load WA and the predetermined first period TA may be values determined according to the time zone in the same elevator system 100, or may be learned and updated. May be.

  In FIG. 5, it is determined whether or not the load in the car W at the time of departure from the elevator is equal to or greater than a predetermined second load WB (step S304). In step S304, when the car load W when the car 7 departs is equal to or greater than the predetermined second load WB, the process proceeds to the next step S305. When the car load W when the car 7 departs is less than the predetermined second load WB, it is determined that the traffic demand for the hall call in the registration floor and the registration direction does not exceed the transport capacity (step S308). Here, the predetermined second load WB is a value greater than or equal to the predetermined first load WA, for example, a load indicating a full state. The predetermined second load WB may be a fixed value regardless of the specification of the elevator system 100, or may be a value determined according to the specification of the elevator system 100. Further, the predetermined second load WB may be a value determined according to the time zone in the same elevator system 100, or may be learned and updated.

  In FIG. 5, if the car load W at the time of departure from the elevator is equal to or greater than the predetermined second load WB in step S304, 1 is added to the variable n in step S305, and the process proceeds to the next step S306. In step S306, it is determined whether or not the variable n is greater than or equal to the predetermined number NA. If the variable n is less than the predetermined number NA, the processes from step S302 to step S306 described above are repeated, and if the variable n is greater than or equal to the predetermined number NA. The traffic demand for the registration floor and the registration direction landing call is determined to have exceeded the transport capacity by a predetermined number of times NA, and the traffic demand for the registration floor and registration direction landing is It is determined that the transport capacity has been exceeded (step S307).

  FIG. 6A is an example in which it is determined in step S308 in FIG. 5 that the traffic demand does not exceed the transport capacity, and the car for time T detected by the weighing device 8 mounted in each car 7 in FIG. It is a graph which shows the change of the internal load W. In the example shown in FIG. 6A, there is a case in which the in-car load W at the time of boarding exceeds a predetermined first period TA among boarding intervals between passengers smaller than the predetermined first load WA. Specifically, the period T13 from time t4 to time t5 and the period T14 from time t5 to time t6, which are passenger boarding intervals, exceed a predetermined first period TA. In this case, the order to the car 7 is good. It is presumed that the boarding has been interrupted, and it does not detect that the traffic capacity exceeds the transport capacity for the hall call in the registration floor and registration direction.

  6B is another example in which it is determined in step S308 in FIG. 5 that the traffic demand does not exceed the transport capacity, and is detected by the scale device 8 mounted on each car 7 in FIG. FIG. 6 is a graph showing changes in the car load W with respect to time T; In the example shown in FIG. 6B, the load in the car W at the time of departure from the elevator is less than the predetermined second load WB, and it is assumed that the passengers in the car 7 have not reached the full state. It does not detect the excess of the transport capacity of the traffic demand for the hall call.

  According to the traffic demand detecting device 20 according to the present embodiment as described above, the traffic demand is determined for each floor and direction based on the temporal change of the load in the car detected by the conventional weighing device in the car. It is possible to detect whether or not the capacity exceeds the capacity, so the camera is not required and the traffic demand for a hall call in a certain direction on a certain floor is generated by passengers exceeding the capacity and the queue is continuously queued at the hall It is possible to quickly detect that the situation is occurring.

  Further, according to the elevator group management device 30 according to the present embodiment, based on the temporal change of the load in the car, it is detected whether the traffic demand for the landing call in the registration floor and the registration direction exceeds the transport capacity, Since the number of vehicles dispatched can be controlled based on the detection result, there is no need for a camera, passengers exceeding the transport capacity are generated for a hall call in a certain direction on a certain floor, and the queue is continuously at the hall It is possible to increase the number of vehicles dispatched only during the occurrence, and effectively reduce congestion.

  Further, according to the elevator system 100 according to the present embodiment, the registration floor and the registration direction are separately classified for each floor and direction based on the temporal change of the load in the car detected by a conventional weighing device provided in the car. Since it is possible to detect whether or not the traffic demand for the landing call exceeds the transport capacity and control the number of vehicles dispatched based on the result, it is possible to eliminate the need for cameras and transport capacity for the registration floor and registration direction call. It is possible to increase the number of dispatched vehicles only during the time when the above passengers are generated and queues are continuously generated at the landing floor of the registration floor, and the congestion can be effectively reduced.

Second embodiment.
The elevator system 100 including the elevator group management device 30 according to the first embodiment is used as a registration floor and a registration direction hall call when the traffic demand for a registration direction hall call on the registration floor detects an excess of transportation capacity. Control to increase the number of assigned vehicles. On the other hand, the elevator system 100A provided with the elevator group management device 30A according to the second embodiment of the present invention further detects when the traffic demand for the landing call in the registration floor and the registration direction exceeds the transport capacity, It is possible to determine how much the number of cars 7 allocated to the registration floor is to be increased based on the state of the queue generated at the registration floor landing.

  FIG. 7 is a block diagram showing a configuration of an elevator system 100A including an elevator group management device 30A according to the second embodiment of the present invention and its peripheral components. Compared to the elevator group management device 30 shown in FIG. 1, the elevator group management device 30 </ b> A includes a traffic demand detection device 20 </ b> A instead of the traffic demand detection device 20, and vehicle allocation control instead of the vehicle allocation control unit 32. A portion 32A is provided. Further, the traffic demand detection device 20A is characterized by including a demand detection unit 23A instead of the demand detection unit 23, as compared with the traffic demand detection device 20 shown in FIG. The configuration of the elevator system 100A shown in FIG. 7 is the same as the configuration of the elevator system 100 shown in FIG.

  In FIG. 7, the demand detection unit 23 </ b> A detects whether or not the traffic demand for the hall call in the registration floor and the registration direction exceeds the transport capacity based on the boarding situation information stored in the storage unit 22 for each floor and direction. When it is determined that the transport capacity has been exceeded by executing the boarding status detection process, the queue status generated at the landing floor of the registered floor is further detected, and the result of the status of the queue is assigned to the vehicle allocation control unit 32A. Output to. Here, the situation where the traffic demand for the hall call for the registration floor and the registration direction exceeds the transport capacity is that passengers exceeding the transport capacity of the elevator system 100A are generated for the hall call of the registration floor and the registration direction. A situation where queues are continuously generated at the landing. According to this configuration, it is possible to detect the state of the queue occurring at the landing on the floor where passengers exceeding the transportation capacity are generated based on the temporal change of the load in the car, thus eliminating the need for a camera. Thus, it is possible to quickly detect the state of the queue.

  In FIG. 7, the dispatch control unit 32A receives the detection result of the queue state generated at the registration floor landing from the demand detection unit 23A, and the number of dispatched vehicles is determined in advance based on the detection result. A command signal for instructing how much to increase from the original number of dispatched vehicles is generated, and the command signal is output to the group management control unit 31. According to this configuration, the state of the queue generated at the landing floor of the registered floor where the excess of the transport capacity is detected is detected based on the temporal change of the load in the car, and the number of vehicles dispatched is controlled based on the result. Therefore, it is possible to determine how much the number of vehicles to be dispatched should be increased based on the state of the queue without using a camera, so that congestion can be more effectively reduced.

  For example, in the previous detection process by the demand detection unit 23A, if the excess of the transport capacity is not detected or the state of ride-through is detected, and the state of the long matrix or the short matrix is detected in the current detection process, the vehicle allocation control The unit 32A issues a command signal for instructing the group management control unit 31 to increase the number of dispatched vehicles assigned to the registration floor and registration direction hall calls to a predetermined number of dispatched vehicles (first dispatched vehicle number). The command signal is generated and output to the group management control unit 31. At this time, when a long queue state in which the queue length is larger than the predetermined threshold is detected, the queue length is shorter than that in a short queue state in which the queue length is equal to or less than the predetermined threshold. A command signal for commanding the number of vehicles to be dispatched is generated, and the command signal is output to the group management control unit 31. That is, in the previous detection process by the demand detection unit 23A, when the short matrix state is detected, and in the current detection process, the long matrix state is detected, the vehicle allocation control unit 32A calls the hall for the registration floor and the registration direction. When the group management control unit 31 is instructed to further increase the number of vehicles allocated to the vehicle, the state of the long matrix is detected in the previous detection process by the demand detection unit 23A, and the state of the short matrix is detected in the current detection process The vehicle allocation control unit 32 instructs the group management control unit 31 to reduce a part of the number of vehicles allocated up to the previous time. According to this configuration, since it is possible to detect that the queue is in a relatively long state by the fact that each passenger is getting on quickly, the scale of the queue occurring at the landing can be reduced. It is possible to detect with high accuracy and to appropriately control the number of vehicles allocated according to the size of the queue.

  Further, the vehicle allocation control unit 32A, when the detection result of the queue state from the demand detection unit 23A is the same as the previous detection result, the vehicle allocation control unit 32A does not change the number of vehicles allocated. A command signal to be commanded is generated and the command signal is output to the group management control unit 31. Further, when the detection result of the queue state from the demand detection unit 23A is a ride-through state, the vehicle allocation control unit 32A returns the number of vehicles allocated to the hall call for the registration floor and the registration direction to the first vehicle allocation number. A command signal for commanding is generated, and the command signal is output to the group management control unit 31. According to this configuration, based on the temporal change of the load in the car, the state of the queue occurring at the landing on the floor where the excess of the transport capacity is detected is detected, and the number of dispatched vehicles is controlled based on the result. Therefore, it is possible to determine how much the number of vehicles to be dispatched should be increased based on the state of the queue, eliminating the need for a camera, so that congestion can be more effectively mitigated. Here, the state of the queue will be described below.

  First, the ride-on state means a state in which all waiting passengers have entered the car 7 of the elevator system 100A that departed this time on the registration floor, and the queue generated at the registration floor landing is gone. Therefore, it is considered that the state of ride-off occurs when the number of waiting passengers when the car 7 arrives at the registration floor is the same as or slightly smaller than the passenger capacity of the car 7. In such a situation, if passengers get on smoothly until the inside of car 7 becomes full, only a few people will remain on the registration floor landing, but the remaining passengers will be waiting because the passengers already in the car 7 are packed. Since all the passengers can also get through, it is assumed that the car 7 starts after all the remaining waiting passengers get on while the passengers in the car 7 are packed. In such a riding situation, the inside of the car 7 is congested to some extent and the boarding interval between passengers who ride after that is somewhat longer, and the load on the car at the time of departure from the elevator is several passengers than the load indicating the normal full state It is considered that the load becomes larger by the load of the minute. Further, if it is not in the state of ride-over, it is assumed that there is a queue at the landing on the registration floor even after the car 7 that has arrived at the registration floor this time has left.

  Next, a long queue means a case where this queue is a relatively long queue, and a short queue means a case where this queue is a relatively short queue. In the case of a long queue, it is assumed that each passenger gets on quickly compared to the case of a short queue. In such a boarding situation, passengers ride smoothly until the inside of the car 7 is congested to some extent, so it is considered that the boarding interval between the passengers is shorter than in the case of a short queue. Based on the above, the state of the queue occurring at the landing floor is detected.

  FIG. 8 is a flowchart showing a queue state detection determination process executed by the demand detection unit 23A of FIG. The flowchart of FIG. 8 is compared to the flowchart of detecting only whether or not the transportation capacity is exceeded in FIG. 2 when it is determined that the transportation capacity has been exceeded in step S105 of the flowchart of FIG. 2 according to the first embodiment. Further, the present invention is characterized in that the state of a queue occurring at a landing on the registered floor is detected.

  In FIG. 8, step S105 is the same as the process of step S105 in the flowchart of FIG. 2 according to the first embodiment. If it is determined that the traffic demand has exceeded the transport capacity, the process moves to the next step S402, and if it is determined that the transport capacity has not been exceeded, the queue state detection determination process ends (step S401). In step S402 and subsequent steps, the state of the queue generated at the landing is detected based on the boarding status information of the passengers who have boarded the car 7 after the car 7 arrives at the registration floor and departs. Specifically, it is detected whether the state of the queue has been overcome and is a long queue or a short queue.

  In FIG. 8, in step S402, it is determined whether there is a boarding interval between passengers whose car load W at the time of boarding exceeds a predetermined first load WA that exceeds a predetermined first period TA. To do. If there is a boarding interval between passengers whose car load W at the time of boarding exceeds a predetermined first load WA that exceeds a predetermined first period TA, in step S403, the inside of the car at the time of departure from the elevator It is determined whether or not the load W is equal to or greater than a predetermined third load WC. The predetermined third load WC is set to a value equal to or greater than the predetermined second load WB, for example, a load slightly heavier than a load indicating that a passenger getting in the car 7 is full. Here, the predetermined third load WC may be a fixed value regardless of the specification of the elevator system 100A, or may be a value determined according to the specification of the elevator system 100A. Further, the predetermined third load WC may be a value determined according to a time zone in the same elevator system 100A, or may be a value that is learned and updated. If the car load W at the time of departure from the elevator is equal to or greater than the predetermined third load WC, it is determined that the state of the queue is a ride-on state and is output (step S406). According to this configuration, it is detected that all the waiting passengers have gone through due to the riding situation in which the ride continues even after the inside of the car 7 is congested to some extent, and the departure is in a state where the car is more crowded than usual. Therefore, it is possible to accurately detect that there is no queue in the hall on the registration floor and quickly return the number of dispatched vehicles to the original number of dispatched vehicles.

  In FIG. 8, in step S <b> 402, when there is no boarding interval between passengers whose car load W at the time of boarding is equal to or greater than a predetermined first load WA, and does not exceed a predetermined first period TA, and If the car load W at the time of departure from the elevator is not equal to or greater than the predetermined third load WC in step S403, the average boarding interval is calculated in step S404. Here, the average boarding interval is defined as an average value of the boarding intervals between the passengers in which the car load W at the time of boarding is smaller than the predetermined first load WA. In step S405, it is determined whether or not the average boarding interval is within a predetermined second period TB. If the average boarding interval is within the predetermined second period TB, it is determined that the queue state is a long queue state (step S407), and the average boarding interval is set to the predetermined second period TB. If it exceeds, the queue state is judged to be a short queue state and output (step S408). Here, the short queue refers to a queue whose queue length is equal to or smaller than a predetermined threshold, and the long queue refers to a queue whose queue length is greater than a predetermined threshold. The predetermined second period TB is set to a value smaller than the predetermined first period TA, for example, a standard time required for one passenger to get on. According to this configuration, since it is detected that the queue is in a relatively long state due to the boarding situation in which each passenger is boarding quickly, the scale of the queue occurring at the landing floor of the registration floor is determined. It becomes possible to detect with high accuracy. Here, the predetermined second period TB may be a fixed value regardless of the specification of the elevator system 100A, or may be a value determined according to the specification of the elevator system 100A. Further, the predetermined second period TB may be a value determined according to a time zone in the same elevator system 100A, or may be a value that is updated by learning.

  FIG. 9A is an example in which it is determined in step S406 in FIG. 8 that the state of the queue is a ride-through state, and the car for time T detected by the weighing device 8 mounted in each car 7 in FIG. It is a graph which shows the change of the internal load W. In FIG. 9A, among the boarding intervals between passengers whose car load W at the time of boarding is equal to or greater than a predetermined first load WA, the boarding interval from the boarding time at time t7 to the boarding time at time t8, and at time t9 The boarding interval from the boarding time point to time t10 exceeds the predetermined first period TA. Therefore, in the example shown in FIG. 9A, there is a boarding interval between passengers whose car load W at the time of boarding exceeds a predetermined first load WA that exceeds a predetermined first period TA, and Since the car load W at the time of departure from the elevator is equal to or greater than a predetermined third load WC, the state of ride-off is detected. Specifically, both of the period T11 between time t7 and time t8, which are intervals at which passengers get on, and the period T12 between time t9, and time t10, which is intervals at which passengers get on, exceed the predetermined first period TA. The car load W at the departure time Td when the elevator departs is equal to or greater than a predetermined third load WC. According to this configuration, the ride continues even after the car 7 is congested to a certain extent, and it is detected that all the waiting passengers have gone through due to the boarding situation such that the car departs in a state that is more crowded than usual. Therefore, it is possible to accurately detect that there is no queue in the hall.

  FIG. 9B is an example of determining that the queue state is a long queue state in step S407 of FIG. 8, and the time detected by the scale device 8 mounted in each car 7 of FIG. 7. 3 is a graph showing a change in a car load W with respect to T. In FIG. 9B, the chain line indicates the inside of the car with respect to the time T when the boarding load W at the time of boarding is smaller than the predetermined first load WA and the boarding intervals between the passengers are all in the predetermined second period TB. The change of the load W is shown. Therefore, in the example shown in FIG. 9B, the time T1 when the last passenger gets in the car, where the load in the car W is smaller than the predetermined first load WA, and the car load W at the time of boarding is the predetermined first load WA. Since the time T2 at the time of the last passenger's boarding does not exceed the time T2 of the last passenger when the boarding intervals between the passengers are all within the predetermined second period TB, the load in the car W at the time of boarding is the predetermined first load. The average boarding interval of the boarding intervals between passengers smaller than WA is determined to be within a predetermined second period TB, and the state of the long matrix is detected.

  Further, FIG. 9C is an example in which it is determined in step S408 in FIG. 8 that the queue state is a short queue state, and the time detected by the scale device 8 mounted on each car 7 in FIG. 3 is a graph showing a change in a car load W with respect to T. In FIG. 9C, the chain line indicates the inside of the car with respect to the time T when the boarding load W at the time of boarding is less than the predetermined first load WA and the boarding intervals between the passengers are all in the predetermined second period TB. The change of the load W is shown. Therefore, in the example shown in FIG. 9C, the time T1 when the last passenger gets in the car, where the in-car load W is smaller than the predetermined first load WA, and the in-car load W at the time of boarding is the predetermined first load WA. When the boarding interval W between the passengers is less than the time T2 when the last passenger boarded when all the boarding intervals between the passengers are within the predetermined second period TB, the load W in the car at the time of boarding is the predetermined first load WA. It is judged that the average boarding interval of the boarding intervals between passengers smaller than the predetermined second period TB is detected, and the state of the short matrix is detected.

  In addition, according to the elevator group management device 30A according to the present embodiment, based on the temporal change of the load in the car, the state of the queue occurring at the landing on the registered floor where excess transport capacity is detected is detected. Because the number of vehicles dispatched can be controlled based on the result, it is possible to determine how much the number of vehicles dispatched should be increased based on the status of the queue, eliminating the need for cameras. Congestion can be alleviated.

  Further, according to the elevator system 100A according to the present embodiment, the state of the queue occurring at the landing on the floor where the excess of the transport capacity is detected is detected based on the temporal change of the load in the car, and the result The number of vehicles dispatched can be controlled based on the number of vehicles, so it is possible to determine how much the number of vehicles dispatched should be increased based on the status of the queue, eliminating the need for cameras.
