The control panel 24 can be obtained from the car 11 via the tail cord 26.

  In addition, a door sensor 27 of, for example, a 3D type that detects an elevator user 22 trying to get on and off the car 11 is disposed above the elevator hall 10 in each elevator hall side door 20. Also, as shown in FIG. 2, call buttons 28A and 28B for the elevator user 22 in the elevator hall EH to call the car 11 to ascend or descend to an upper floor or a lower floor. Are arranged.

  The door sensors 27 and the call buttons 28A and 28B of each level are connected to the control panel 24 via signal lines (not shown) laid in the hoistway 10. Thus, the control panel 24 can obtain the detection result of the door sensor 27 and the information regarding the pressing operation of the elevator user 22 on the call buttons 28A and 28B via the communication line.

  The control panel 24 is a control unit having a function of controlling the operation of each elevator 2. The control panel 24 is operated by the elevator user 22 (operation of a destination floor button corresponding to a destination floor, operation of a door open / close button) on an operation panel installed in the car 11 of the elevator 2, and an elevator of each level. The hoisting machine 13 is controlled so as to stop the car 11 on a required level based on the pressing operation of the call buttons 28A and 28B respectively installed in the hall EH and the detection result of the elevator user 22 by the door sensor 27. The door opening / closing mechanism 19 is controlled to open and close the doors of the car 11 (car side door 18 and elevator hall side door 20; the same applies hereinafter).

  Further, the management panel 25 detects the flow (people flow) of the elevator users 22 in the elevator halls EH of the respective levels based on various information collected by the building management server 3 as described later, and based on the detection result, the control panel 24. Is a management unit having a function of managing Specific processing contents of the management panel 25 will be described later.

  At the bottom of the hoistway 10, shock absorbers 29A and 29B are provided in correspondence with the car 11 and the counterweight 15, respectively. The shock absorbers 29A and 29B can buffer the shock.

  On the other hand, the building management server 3 is a general-purpose server device provided with information processing resources such as a CPU (Central Processing Unit), a memory, and a hard disk device. The building management server 3 is provided with information from an entrance gate 30 installed on the first floor of the building, a human sensor 31 and a monitoring camera 32 installed on each floor via a building network 33.

  In practice, the entrance gate 30 is arranged at the entrance of the elevator hall EH on the first floor, and reads the authentication information from the personal authentication card held by the elevator user 22 entering the elevator hall EH and held over the wireless communication unit 30A. The authentication information transmitted to the building management server 3 via the building network 33.

  As shown in FIGS. 1 and 2, the human sensor 31 is installed at regular intervals on the ceiling of each floor in the building including the elevator halls EH of each floor, and detects infrared rays emitted from the surface of the human body and the own sensor. It detects the presence or absence of a person approaching based on the reflected waves of the ultrasonic waves or microwaves emitted from the surface of the human body, and transmits the detection result to the building management server 3 via the building network 33 as the person detection information. Further, the monitoring camera 32 is installed on the ceiling of each floor. The monitoring camera 32 notifies the building management server 3 of the video data of the captured video via the building network 33.

  The building management server 3 authenticates the elevator user 22 based on the authentication information given from the entrance gate 30, and controls, for example, a destination floor preset for the elevator user 22 based on the authentication result. Register on the board 24. Thus, the control panel 24 controls the operation of the elevator 2 so as to stop at that level.

  Further, the building management server 3 accumulates the human detection information given from each human sensor 31 and the video data given from each monitoring camera 32, and accumulates these in response to a request from the management panel 25. The information is provided to the management panel 25.

(2) Door open / close control function Next, a door open / close control function mounted on the elevator system 1 of the present embodiment will be described. The elevator system 1 has a door opening / closing control function for controlling opening and closing of the doors of the elevator 2 so that as many elevator users 22 as possible can get on the car 11.

  Actually, in the case of the present elevator system 1, the management panel 25 determines the human detection information collected by the building management server 3 and output from each human sensor 31 and the video data of the video captured by each monitoring camera 32. It is acquired from the building management server 3 at the timing. Further, the management panel 25 detects the flow (people flow) of the elevator user 22 in the elevator hall EH of the level where the car 11 of each elevator 2 is stopped, based on the acquired person detection information and the video data, At that time, the number of elevator users 22 trying to get on the car 11 is estimated.

  Then, the management panel 25 allows the estimated number of elevator users 22 for the elevator 2 in a state in which the door of the car 11 is open to be able to ride on the car from the viewpoint of limiting the loading of the car 11, Further, when all of the elevator users 22 are in a state where they can get on the car 11 within a predetermined time, a time for keeping the door of the car 11 of the elevator 2 open (hereinafter, this is referred to as a door opening time) The control panel 24 is controlled so as to extend a predetermined time from a preset time (hereinafter, referred to as a set door opening time). As a result, the door opening time of the elevator 2 is extended from the set door opening time, and more elevator users 22 can enter the car 11.

  In contrast, the management panel 25 predicts that not all of the estimated number of elevator users 22 can get on the car or that all of the elevator users 22 cannot get on the car 11 within a certain time. In such a case, the control described above for the control panel 24 is not performed. Thereby, the door of the elevator 2 is closed in the normal door opening time without extending the door opening time of the elevator 2. As a result, it is possible to suppress the occurrence of the operation delay of the elevator 2 due to the door being unduly opened for a long time.

  FIGS. 3A and 3B show a specific procedure of the door opening / closing control process executed by the management panel 25 in connection with the above-described door opening / closing control function. The management panel 25 controls opening and closing of the doors of each elevator 2 as described above by giving necessary instructions to the control panel 24 in accordance with the processing procedure shown in FIGS. 3A and 3B. 3A and 3B are processes for one elevator 2, and similar processes are executed for each elevator 2.

  Actually, this door opening / closing control process is started when the car 11 of the elevator 2 arrives at the elevator hall EH of any hierarchy. First, the management panel 25 sends the elevator (hereinafter referred to as the target elevator). The target elevator 2 is opened by controlling the door opening / closing mechanism 19 (S1). When the door of the target elevator 2 is completed, the management panel 25 causes a timer (not shown) provided therein to start counting up.

  Subsequently, the management panel 25 acquires the count value of the timer as the elapsed time (door opening time) after opening the door of the target elevator 2 (S2), and the door opening time reaches the set door opening time. It is determined whether or not it has been performed (S3).

  If the management panel 25 obtains a negative result in this determination, the management panel 25 determines whether or not the door closing button of the operation panel has been pressed based on information given from the operation panel in the car 11 of the target elevator 2. (S4). When the management panel 25 obtains a negative result in this determination, the process returns to step S2, and thereafter, the processing of steps S2 to S4 is repeated until a positive result is obtained in step S3 or step S4.

  When the management panel 25 eventually obtains a positive result in step S4 by detecting that the door closing button of the operation panel in the car 11 of the target elevator 2 is pressed, the process proceeds to step S14.

  On the other hand, if the control panel 25 obtains a positive result in step S3 because the door opening time of the target elevator 2 reaches the set door opening time, the level at which the car 11 of the target elevator 2 is stopped at that time. The human detection information output from each human sensor 31 and the video data of the video captured by the monitoring camera 32 at that level are acquired from the building management server 3 via the building network 33 (S5). Further, the management panel 25 detects the flow of the elevator user 22 in the elevator hall EH of that level based on the acquired person detection information and the video data (S6).

  Subsequently, based on the detection result of step S6, the management panel 25 determines whether the elevator user 22 who is going to get on the car 11 in the elevator hall EH of the hierarchy where the car 11 of the target elevator 2 is stopped. The number of people is estimated (S7).

  This estimation can be performed, for example, by counting the number of elevator users 22 existing within a certain distance from the door of the target elevator 2 based on the video data and the human detection information acquired in step S5. . The management panel 25 then uses the recognition camera such as face recognition for each of the elevator users 22 counted at this time (hereinafter, these are respectively referred to as target elevator users 22), and performs monitoring camera 32 ( Each of these target elevator users 22 is tracked in the captured images of FIGS. 1 and 2).

  Subsequently, the management panel 25 determines whether or not all the target elevator users 22 can get on the car 11 of the target elevator 2 from the viewpoint of restricting the loading of the target elevator 2 (S8). This determination is made in this step S8 by multiplying the average weight of the elevator user 22 set in advance by the number of persons estimated in step S7, and using the multiplication result by the load sensor 23 of the car of the target elevator 2 (FIG. 1). This can be performed by adding the detected current load and determining whether or not the result of the addition is less than the maximum loading load preset for the car 11.

  When the management panel 25 obtains a negative result in this determination, the process proceeds to step S13. On the other hand, if the management panel 25 obtains a positive result in the determination in step S8, all the target elevator users 22 will be within a predetermined time (hereinafter, this is referred to as a first threshold time). It is determined whether or not the car 11 can be reached (S9).

  In this determination, the walking speed of each target elevator user 22 is calculated using the video data from the surveillance camera 32, and the calculated walking speed of each target elevator user 22 and the target walking speed of the target elevator user 22 are calculated. Based on the current distance to the door of the elevator 2, the time required for each of the target elevator users 22 to arrive at the door of the target elevator 2 (hereinafter referred to as an estimated arrival time) is calculated and calculated. By determining whether the largest predicted arrival time is less than the first threshold time.

  When the management panel 25 obtains a negative result in this determination, the process proceeds to step S14. On the other hand, if the management panel 25 obtains a positive result in the determination in step S9, the total load of the car 11 at that time given from the load sensor 23 installed on the car 11 of the target elevator 2 is obtained. Is estimated based on the sensor information (hereinafter, referred to as load detection information) indicating the number of elevator users 22 that can further ride the car 11 of the target elevator 2 at that time (S10).

  This estimation is performed by subtracting the current load weight of the car 11 recognized based on the load detection information from the preset maximum load weight of the car 11 of the target elevator 2 and setting the subtraction result in advance. This can be done by dividing the average weight of the elevator user 22 by the weight.

  Subsequently, the management panel 25 determines whether or not the number calculated in step S is “1” or more (S11). When the control panel 25 obtains a positive result in this determination, the control panel 25 gives an instruction to the control panel 24 to extend the door opening time of the target elevator 2 by a predetermined time from the set door opening time (S12), and thereafter, proceeds to step S5. Return. Further, thereafter, the management panel 25 repeats the processing of steps S5 to S12 until a negative result is obtained in any of steps S8, S9, and S11.

  Then, when a negative result is obtained in any of step S8 and step S11, the management panel 25, for example, outputs a predetermined buzzer sound or a predetermined buzzer sound from a speaker (not shown) in the car 11 of the target elevator 2. By giving an instruction to the control panel 24 to output a sound, the control unit 24 notifies the elevator user 22 in the car 11 of closing the door of the target elevator 2 (S13).

  Subsequently, the management panel 25 sets the door sensor 27 to the target car 2 based on the human detection information given from the door sensor 27 of the target elevator 2 at the level where the car 11 of the target elevator 2 is stopped at that time. It is determined whether or not the elevator user 22 trying to get on the vehicle is detected (S14). If the management panel 25 obtains a positive result in this determination, the control panel 25 returns to step S1, and thereafter repeats the processing from step S1.

  On the other hand, if the management panel 25 obtains a negative result in the determination in step S14, the management panel 25 uses the human detection information output from each of the human sensors 31 in each of the layers in the building and the monitoring cameras 32 in each of the layers. The video data of the captured video is acquired from the building management server 3 via the building network 33 (S15).

  Next, the management panel 25 determines, based on the individual detection information and the video data acquired in step S15, that the car 11 of the target elevator 2 is to be stopped in the next and subsequent hierarchies (hereinafter, these hierarchies will be stopped respectively) (Referred to as a floor) is detected (S16).

  The “schedule to be stopped” here is a hierarchy designated by operating the destination floor button of the operation panel in the car 11, a hierarchy in the traveling direction of the car 11, and is a level in the elevator hall EH. The personal authentication card automatically set in the target elevator 2 based on the hierarchy at which the call buttons 28A and 28B are pressed and the personal information read from the personal authentication card at the entry gate 30 (FIGS. 1 and 2). This corresponds to the destination floor preset for the owner.

  Subsequently, the management panel 25 determines the number of elevator users (target elevator users) 22 who will use the elevator 2 at each scheduled stop floor of the car 11 of the target elevator 2 based on the detection result of step S16. It is estimated in the same manner as in S7 (S17).

  Subsequently, the control panel 25 sets the next stop scheduled floor of the car 11 of the target elevator 2 (hereinafter, referred to as the next stop planned floor) in the elevator hall EH on the level in the traveling direction of the car 11. It is determined whether or not the floor is set as the stop floor by the pressing operation of the call buttons 28A and 28B (S18).

  Here, if a negative result is obtained in this determination, this means that the car 11 of the target elevator 2 must be stopped at the next scheduled stop floor. This is because the corresponding elevator user 22 in the car 11 cannot get off at the next scheduled stop floor unless the car 11 of the target elevator 2 is stopped at the next scheduled stop floor.

  Thus, at this time, the management panel 25 gives an instruction to the control panel 24 to set the next scheduled stop floor to the next stop floor (S19). Then, the control panel 24 sets the scheduled stop floor to the next stop floor of the car 11 of the target elevator 2 according to this instruction, and controls the operation of the target elevator 2 according to this setting.

  On the other hand, if a positive result is obtained in the determination of step S18, this means that the elevator user 22 presses the call buttons 28A and 28B in the elevator hall EH of the corresponding level, and that level is next time. It means that it was set to the scheduled stop floor. In such a case, the car 11 of the target elevator 2 does not necessarily need to be stopped at the next scheduled stop floor, and can pass through the next scheduled stop floor.

  Thus, at this time, from the viewpoint of the maximum loading weight of the car 11 of the target elevator 2, the management panel 25 assigns the elevator users 22 of the number of persons who intend to use the elevator 2 at the next scheduled stop floor estimated in step S <b> 17. It is determined whether all the cars 11 of the target elevator 2 can be boarded (S20).

  If the control panel 25 obtains a negative result in this determination, the control panel 25 instructs the control panel 24 to pass the car 11 of the target elevator 2 to the next scheduled stop floor without stopping (S21). Thus, the control panel 24 operates the target elevator 2 in the full-pass operation mode in accordance with the instruction, thereby passing the next scheduled stop floor. The management panel 25 returns to step S17, and thereafter performs steps S17 to S21 in the same manner as described above until a negative result is obtained in step S18 or a positive result is obtained in step S20.

  When a positive result is obtained in the determination of step S20, the management panel 25 gives an instruction to the control panel 24 so that the floor which was set as the next stop scheduled floor in step S17 is set as the next stop floor (S22). . Then, the control panel 24 sets the next stop scheduled floor to the next stop floor of the car 11 of the target elevator 2 according to this instruction.

  Further, the management panel 25 gives an instruction to the control panel 24 to cause the car 11 of the target elevator 2 to depart from the current level (S23), and thereafter ends this door opening / closing control processing.

(3) Effect of the present embodiment As described above, in the elevator system 1 of the present embodiment, the human detection information output from the human sensor on the stop floor of the elevator 2 and the captured image output from the surveillance camera Based on the video data, an elevator user 22 trying to get on the car 11 of the elevator 2 at that level is detected, and the total weight of the detected elevator users 22 and the arrival time to the car 11 are estimated. However, when it is estimated that all of the elevator users 22 can ride on the car 11 from the viewpoint of the loading restriction of the car 11 and that all of the elevator users 22 can ride on the car 11 within a predetermined time, The door opening time of the car 11 is extended from the set door opening time.

  Therefore, according to the present elevator system 1, while increasing the number of transporters of the elevator users 22 per one elevator 2, the occurrence of the operation delay of the elevator 2 due to the extended door closing time is suppressed. Thus, the transportation efficiency of the elevator 2 can be improved without causing an operation delay.
