[Structure of Passenger Conveyor]

First, with reference to FIG. 1, the structure of the passenger conveyance apparatus 1 which concerns on one Embodiment of this invention is demonstrated. 1 : is a figure which shows the passenger conveyance apparatus 1 which concerns on one Embodiment of this invention.

[Hardware structure of the control unit]

Next, the hardware configuration of the control unit 11 will be described with reference to FIG. 2 . FIG. 2 is a diagram for explaining the hardware configuration of the control unit 11 according to one embodiment of the present invention.

In addition, the control unit 11 may include a processing device such as an MPU (Micro-Processing Unit) instead of the CPU 21 .

[Structure of Operation Control System]

Next, the configuration of the operation control system 100 of the present embodiment will be described with reference to FIG. 3 . FIG. 3 is a block diagram showing the operation control system 100 according to one embodiment of the present invention.

As shown in FIG. 3 , the operation control system 100 in the present embodiment includes a control unit 11 to which a drive device 10 , a speaker device 12 , an elevator entrance side camera 13 , and a descending elevator entrance side camera 14 are connected.

The CPU 21 (see FIG. 2 ) of the control unit 11 functions as a signal unit 31 , an arithmetic unit 32 , and a detection unit 34 by executing a program stored in the ROM 22 . In addition, the storage unit 33 shown in FIG. 3 is constituted by the ROM 22 and the RAM 23 of the control unit 11 . The ROM 22 of the storage unit 33 stores data, parameters, and the like used in various processes executed by the signal unit 31 , the arithmetic unit 32 , and the detection unit 34 . In addition, the RAM 23 of the storage unit 33 functions as a work area when the signal unit 31 , the calculation unit 32 , and the detection unit 34 execute various processes.

The signal unit 31 functions as an imaging data receiving unit that receives imaging data transmitted from the camera 13 on the side of the elevator entrance and the camera 14 on the side of the elevator entrance.

The arithmetic unit 32 executes the operation control process at a predetermined cycle, in this embodiment, every 40 msec. In the operation control process, the calculation unit 32 causes the signal unit 31 to execute the passenger density detection process and the passenger speed detection process. In the passenger density detection process, the signal unit 31 detects the passenger density from the received imaging data. That is, the signal unit 31 functions as a density detection unit that detects the density of passengers based on the imaging data.

Here, the imaging data transmitted from the camera 14 on the side of the elevator entrance will be described with reference to FIG. 4 . FIG. 4 is a diagram for explaining imaging data according to an embodiment of the present invention.

As shown in FIG. 4 , the imaging data transmitted from the camera 14 on the side of the escalator is composed of images of the escalator 7 and its vicinity, and there are cases in which images of passengers descending from the passenger conveying device 1 are included.

The signal unit 31 performs pattern matching using the pattern image of the passenger stored in advance in the storage unit 33, and extracts the image of the passenger from the received imaging data. Then, when the image of the passenger can be extracted from the imaging data, the signal unit 31 detects the passenger density at the exit (the exit 7 and its vicinity) based on a predetermined reference, and stores the detected passenger density. In the RAM 23 constituting the storage unit 33 . Here, the density of passengers at the exit (the exit 7 and its vicinity) refers to the density of passengers who get down from the passenger conveying device 1 at the exit.

The predetermined reference for detecting the passenger density can be appropriately set according to the performance of the passenger conveying apparatus 1, the installation location, the required safety performance, and the like. For example, in the present embodiment, when it can be estimated from the extracted images of the passengers that there are two passengers on each of the consecutive steps 5, that is, in the case of the view from the imaging data (as shown in FIG. 4 ) When the image of four passengers can be extracted, the passenger density is detected as 100% of the passenger density. Similarly, when images of three passengers can be extracted from the imaging data (field of view) as shown in FIG. 4, the passenger density is detected as 75%, and in the case of two, it is detected as 50%, In one case, the detection was 25%.

In addition, in the passenger speed detection process, the signal unit 31 detects the moving speed of the passenger getting off the elevator from the passenger conveying device 1 at the exit (the exit 7 and its vicinity) from the received imaging data. Specifically, the signal unit 31 performs pattern matching for each of the continuously received imaging data using the pattern image of the passenger pre-stored in the storage unit 33, and extracts the image of the passenger from the received imaging data. Then, the travel distance of the passenger is calculated from changes in the image of the passenger in the continuously received imaging data, and the travel speed of the passenger, that is, the passenger speed, is detected based on the calculated travel distance and the frame rate of the imaging data. Therefore, the signal part 31 functions as a speed detection part which detects the moving speed (passenger speed) of a passenger based on the imaging data.

Here, in the case where images of a plurality of people, for example, four passengers can be extracted for each of the continuously received imaging data, there are cases where the speeds of four passengers are detected, but in this case, the average value of them is as passenger speed. Then, the signal unit 31 stores the detected speed of the passenger in the RAM 23 constituting the storage unit 33 .

In addition, in the operation control process, the calculation unit 32 causes the detection unit 34 to detect the occupancy rate (so-called "passenger load") of passengers in the passenger conveyance apparatus 1 . The occupancy rate in the present embodiment is detected based on inverter load information (eg, supply power information indicating the magnitude of the supplied power) from the inverter device 17 that supplies power to the drive device 10 . Specifically, a value obtained by multiplying the value obtained by dividing the power supply information transmitted from the inverter device 17 to the drive device 10 by the power supply information in the design maximum loading capacity at the time of measurement by 100[%] To represent. The detection unit 34 stores the detected occupancy rate in the RAM 23 constituting the storage unit 33 . That is, the detection unit 34 functions as an occupancy rate detection unit that detects the occupancy rate of passengers.

In the operation control process, the computing unit 32 compares the detected passenger density, passenger speed, and occupancy rate with respective corresponding threshold values. In addition, the arithmetic unit 32 refers to the determination table stored in the storage unit 33, and determines the state of congestion based on the comparison result. Then, the calculation unit 32 controls the drive device 10 according to the determined congestion situation, and controls the moving speed of the plurality of steps 5 .

Next, referring to FIG. 5 , the determination table referred to by the computing unit 32 in the operation control process will be described with reference to FIG. 5 . FIG. 5 is a diagram showing a judgment table according to an embodiment of the present invention.

As shown in FIG. 5 , as threshold values corresponding to each of the passenger density, the passenger speed, and the occupancy rate, two types of threshold values corresponding to the degree of congestion are set.

Specifically, as the threshold value corresponding to the passenger density, the threshold value A and the threshold value B are set. In this embodiment, the threshold value A is set to 25(%), and the threshold value B is set to 75(%). When the detected passenger density is less than the threshold value A, it can be determined that the passenger density is low. In addition, when the detected passenger density is equal to or greater than the threshold value A and less than the threshold value B, it can be determined that the passenger density is moderate. In addition, when the detected passenger density is equal to or greater than the threshold value B, it can be determined that the passenger density is high. Generally, when crowded, the passenger density tends to increase.

As threshold values corresponding to the passenger speed, a threshold value C and a threshold value D are set. In this embodiment, the threshold value C is set to 2 (km/hour), and the threshold value D is set to 4 (km/hour). When the detected passenger speed is less than the threshold value C, it can be determined that the passenger speed is slow. In addition, when the detected passenger speed is equal to or greater than the threshold value C and less than the threshold value D, it can be determined that the passenger speed is normal. In addition, when the detected passenger speed is equal to or greater than the threshold value D, it can be determined that the passenger speed is high. Generally, the passenger speed tends to slow down when crowded.

Threshold value E and threshold value F are set as threshold values corresponding to the boarding rate. In this embodiment, the threshold value E is set to 25(%), and the threshold value F is set to 75(%). When the detected occupancy rate is less than the threshold value E, it can be determined that the occupancy rate is low. In addition, when the detected occupancy rate is equal to or greater than the threshold value E and less than the threshold value F, it can be determined that the occupancy rate is moderate. In addition, when the detected occupancy rate is equal to or greater than the threshold value F, it can be determined that the occupancy rate is high. Generally, when crowded, the occupancy rate tends to increase.

In addition, the values of these thresholds A to F can be appropriately set according to the performance of the passenger conveyance apparatus 1, the installation location, the required safety performance, and the like.

By referring to the determination table shown in FIG. 5 , the computing unit 32 can discriminate the congestion situation as abnormal (congestion: second congestion situation), “ Any of the slight abnormality (slightly crowded: the first crowded state) indicated by G1" and the non-congested condition indicated by "-".

In the judgment table, a crowded situation when the detected passenger density is equal to or greater than the threshold B, the passenger speed is less than the threshold C, and the occupancy rate is equal to or greater than the threshold F is defined as G2, that is, abnormal (congested). In addition, in the judgment table, the congestion situation when the detected passenger density is equal to or greater than the threshold value B, the passenger speed is less than the threshold value C, and the occupancy rate is less than the threshold value E or more than the threshold value E and less than the threshold value F is defined as G1, that is, light. Unusual (slightly crowded).

In addition, in the judgment table, as a case where the congestion situation is defined as G1, that is, slightly abnormal (slightly crowded), the detected passenger density is greater than or equal to the threshold value B, the passenger speed is greater than or equal to the threshold value C and less than the threshold value D. and the occupancy rate is greater than or equal to the threshold value E and less than or equal to or greater than the threshold value F. In addition, there are cases where the detected passenger density is equal to or greater than the threshold value B, the passenger speed is equal to or greater than the threshold value D, and the occupancy rate is equal to or greater than the threshold value F. In addition, there are cases where the detected passenger density is equal to or greater than the threshold value A and less than the threshold value B, the passenger speed is equal to or greater than the threshold value C and less than the threshold value D, and the occupancy rate is equal to or greater than the threshold value F. Also, the detected passenger density is equal to or greater than the threshold A and less than the threshold B, the passenger speed is less than the threshold C, and the occupancy rate is equal to or greater than the threshold E and less than the threshold F, or is equal to or greater than the threshold F. In addition, there are cases where the detected passenger density is insufficient by the threshold value A, the passenger speed is insufficient by the threshold value C, and the occupancy rate is equal to or greater than the threshold value F.

In addition, if the detected passenger density, passenger speed, and occupancy rate are not any of the above, for example, the detected passenger density is less than the threshold A, the passenger speed is less than the threshold C, and the occupancy rate is greater than or equal to the threshold E and less than the threshold F. The situation of congestion in the case of is judged as not crowded (indicated as "-" in the judgment table).

When the state of congestion determined to be slightly abnormal (slightly crowded) in G1, the computing unit 32 outputs a sound indicating congestion and deceleration of the passenger conveying device 1 from the speaker device 12, for example, “Crowded. The conveyor slows down." Such a voice. In addition, in the same case, the calculation part 32 controls the drive apparatus 10, and decelerates the moving speed of the step 5 which is normally set at 30 m/min, for example, to 20 m/min.

When the state of congestion determined to be abnormal (congested) in G2, the computing unit 32 outputs a sound indicating congestion and stopping the passenger conveying device, for example, “Crowded. Stop the passenger conveying device” from the speaker device 12 . "Sounds like that. In addition, in the same case, the computing unit 32 controls the drive device 1 to stop the movement of the step 5 .

Further, when decelerating the moving speed of the steps 5 to 20 m/min, the arithmetic unit 32 causes the speaker device 12 to output a sound indicating that the moving speed of the steps 5 is restored to the normal speed if a predetermined condition is satisfied. Then, the computing unit 32 controls the drive device 10 to accelerate the moving speed of the step 5 to 30 m/min in a normal state. In the present embodiment, the predetermined condition is that after the moving speed of the steps 5 is decelerated to 20 m/min, the occupancy rate which is less than the threshold value E is continuously detected for a certain period of time. In this embodiment, 1 minute is set as a fixed time.

In addition, this predetermined condition can be suitably set according to the performance of the passenger conveyance apparatus 1, an installation place, required safety performance, etc..

Next, an example of detection of passenger density, passenger speed, and occupancy rate by the operation control system 100 of the present embodiment will be described with reference to FIGS. 6A , 6B, and 6C. 6A , 6B and 6C are diagrams showing an example of detection of passenger density, passenger speed, and occupancy rate by the operation control system according to one embodiment of the present invention.

The relationship between the detected passenger density, passenger speed, occupancy rate, and output time at normal times is shown in FIG. 6A . In the example shown in FIG. 6A , the detected passenger density does not become equal to or greater than the threshold value B even if time has elapsed since the detection. In addition, the detected passenger speed does not become insufficient to the threshold value C. Furthermore, the detected occupancy rate does not become the threshold value F or more. Therefore, at any point in time shown in FIG. 6A , the computing unit 32 determines that the congestion is not congested (see FIG. 5 ). Therefore, the calculation part 32 sets the moving speed of the step 5 to 30 m/min and continues the operation of the passenger conveyance apparatus 1 as usual.

FIG. 6B shows the relationship among the detected passenger density, passenger speed, occupancy rate, and output time when the crowded condition is slightly abnormal (slightly crowded). In the example shown in FIG. 6B , at time T1 , the detected passenger density is equal to or greater than the threshold value B, and the detected occupancy rate is equal to or greater than the threshold value E and less than the threshold value F. Further, at the time point T1, the detected passenger speed becomes equal to or greater than the threshold value C and less than the threshold value D. Therefore, the computing unit 32 discriminates that the congestion is slightly abnormal (slightly crowded) at time T1 (see FIG. 5 ). Then, the arithmetic unit 32 outputs from the speaker device 12 a sound indicating congestion and deceleration of the passenger conveying device 1, and controls the drive device 10 to decelerate the moving speed of the steps 5 to 20 m/min. In the example shown in FIG. 6B , in the operation control process executed after the time point T1 , the computing unit 32 determines that the congestion continues to be slightly abnormal (slightly crowded).

FIG. 6C shows the relationship among the detected passenger density, passenger speed, occupancy rate, and output time when the crowded condition is abnormal (congested). In the example shown in FIG. 6C , at the time point T2, the detected passenger density is equal to or higher than the threshold value B, and the detected passenger speed falls below the threshold value C. Further, at the time point T2, the detected passenger density becomes the threshold value F or more. Therefore, the computing unit 32 discriminates that the congestion is abnormal (congested) at time T2 (see FIG. 5 ). Then, the arithmetic unit 32 outputs from the speaker device 12 a sound indicating the crowd and the intention to stop the passenger conveying device 1 , and controls the drive device 10 to stop the movement of the steps 5 . Further, in the example shown in FIG. 6C , in the operation control process executed after the time point T2 , the operation unit 32 determines that the congestion continues to be abnormal (congested).

[Procedure of Operation Control Processing]

Next, the procedure of the operation control process executed by the arithmetic unit 32 will be described with reference to FIG. 7 . 7 is a flowchart showing an operation control process according to an embodiment of the present invention. In addition, as described above, the calculation unit 32 executes the operation control process at a predetermined cycle, every 40 msec in the present embodiment.

First, the calculation part 32 determines whether the passenger conveyance apparatus 1 is operating (S1). When it is determined that the passenger conveying apparatus 1 is not in operation (in the case of NO determination in S1 ), the computing unit 32 ends the operation control process. On the other hand, when it is determined that the passenger conveying apparatus 1 is in operation (in the case of S1 being a YES determination), the calculation unit 32 causes the detection unit 34 to detect the occupancy rate, and compares the occupancy amount detected by the detection unit 34 with the threshold value E and the The threshold value F is calculated (compared) (S2).

Next, the calculation unit 32 causes the signal unit 31 to detect the passenger density and the passenger speed, and perform calculation (comparison) with the respective threshold values (S3). Specifically, the passenger density detected by the signal unit 31 is compared with the threshold value A and the threshold value B. In addition, the passenger speed detected by the signal unit 31 is compared with the threshold value C and the threshold value D.

Next, the computing unit 32 determines whether the congestion situation is G1, that is, whether it is slightly abnormal (slightly crowded), based on the comparison results of steps S2 and S3 and the determination table shown in FIG. 5 (S4). When it is determined that the crowded situation is slightly abnormal (slightly crowded) in G1 (in the case of YES determination in S4 ), the computing unit 32 broadcasts the congestion of the passenger conveyance device ( S5 ). Specifically, the arithmetic unit 32 causes the speaker device 12 to output a sound indicating that it is crowded and that the passenger conveying device 1 is decelerated.

Next, the calculation part 32 controls the drive apparatus 10, and decelerates the moving speed of the step 5 (S6). Specifically, the arithmetic unit 32 decelerates the moving speed of the step 5 to 20 m/min. And after the process of step S6, the arithmetic part 32 complete|finishes an operation control process. In addition, when transitioning to step S6, if the moving speed of step 5 is in a decelerating state, the calculation unit 32 omits the processing of step S6 and ends the operation control process (in this case, the moving speed of step 5 is kept decelerating unchanged, that is, keep 20m/min as it is).

In step S4, when it is determined that the crowded situation is not slightly abnormal (slightly crowded) in G1 (in the case of NO determination in S4), the calculation unit 32 uses the results of the comparison between steps S2 and S3 and the results shown in FIG. 5 . The shown judgment table is used to judge whether or not the congestion situation is G2, that is, whether it is abnormal (congested) (S7). When it is determined that the crowded situation is abnormal (congested) in G2 (in the case of YES determination in S7 ), the computing unit 32 broadcasts the congestion of the passenger conveyance device ( S8 ). Specifically, the computing unit 32 causes the speaker device 12 to output a sound indicating that it is crowded and that the passenger conveying device 1 is stopped.

Next, the calculation part 32 stops the passenger conveyance apparatus 1 (S9). Specifically, the arithmetic unit 32 controls the drive device 10 to stop the movement of the step 5 . And after the process of step S9, the calculation part 32 complete|finishes the operation control process. When transitioning to step S9, when step 5 is in a stopped state, the computing unit 32 omits the process of step S9 and ends the operation control process (in this case, step 5 remains stopped).

In step S7 , when it is determined that the crowded situation is not abnormal (congested) in G2 (in the case of NO determination in S7 ), the computing unit 32 determines whether or not the passenger conveyor 1 is decelerating, that is, whether the moving speed of the step 5 is not. The deceleration is kept unchanged (S10). When it is determined that the passenger conveying apparatus 1 is not decelerating (in the case of NO determination in S10 ), the computing unit 32 ends the operation control process. On the other hand, when it is determined that the passenger conveying apparatus 1 is decelerating (in the case of YES determination in S10 ), the computing unit 32 transfers the process to step S11 .

In step S11, the computing unit 32 determines whether or not a predetermined time has elapsed in the state where the occupancy rate is less than the threshold value E (S11). Specifically, the computing unit 32 determines whether or not the occupancy rate less than the threshold value E is continuously detected for a certain period of time after the speed of movement of the step 5 is decelerated. In addition, in order to realize this process, the control unit 11 is provided with a timer circuit for determining whether or not a certain period of time has elapsed when the riding rate becomes less than the threshold value E after deceleration and the state is maintained. judgment. Alternatively, the time at which the occupancy rate after deceleration becomes less than the threshold value E for the first time may be stored in the storage unit 33, and the elapsed time may be calculated based on this time and the current time.

When it is determined that the occupancy rate is less than the threshold value E for a certain period of time (in the case of NO determination in S11 ), the computing unit 32 ends the operation control process. On the other hand, when it is determined that the occupancy rate is less than the threshold value E for a certain period of time (YES in S11 ), the computing unit 32 announces the speed recovery of the passenger conveyance device 1 ( S12 ). Specifically, the arithmetic unit 32 causes the speaker device 12 to output a sound to return the moving speed of the step 5 to the speed at the normal time.

Next, the calculation part 32 accelerates the passenger conveyance apparatus 1 (S13). Specifically, the computing unit 32 controls the drive device 10 to accelerate the moving speed of the step 5 to 30 m/min in a normal state. Then, the computing unit 32 ends the operation control process.

[effect]

In the passenger conveyance apparatus 1 and the operation control system 100 of the present embodiment, the density of passengers detected based on the imaging data of the landing camera 14 and the passenger speed and the occupancy rate detected by the detection unit 34 based on the inverter load information are used to determine Determine the congestion situation. Thereby, it is also possible to detect the congestion situation using the information of the users of the passenger conveyance apparatus who have not yet reached the vicinity of the alighting place, and to appropriately control the operation of the passenger conveyance apparatus 1 according to the detected congestion situation.

In addition, the crowded situation is determined based on the imaging data of the escalator side camera 14 attached to the handrail 8 via the fixing member 15, and the operation of the passenger conveying apparatus 1 is appropriately controlled according to the crowded situation. Therefore, it is possible to appropriately control the operation of the passenger conveyance device based on the imaging data without directly installing the imaging device in the building.

In addition, in this Embodiment, although the form which attached the camera to the railing 8 was demonstrated, the structural member of the passenger conveyance apparatus 1 to which the camera is attached can be arbitrarily selected. For example, a column may be erected on the upper floor 2 and the lower floor 3, and a camera may be installed on the column. Moreover, if a camera is installed in the area|region S shown in FIG. 1 in which the passenger conveyance apparatus 1 is installed, it can suppress that a camera interferes with other equipment of a building, and it is preferable.

Here, in the case of judging the crowded situation based on the imaging data of the descent entrance 7 and its vicinity, if the descent entrance 7 and a range farther from the descent entrance 7 can be photographed, it is possible to more accurately confirm the The movement of the passenger who gets off the elevator in the passenger conveying apparatus 1, and the situation in the vicinity of the exit 7. In the area S (refer to FIG. 1 ) in which the passenger conveying apparatus 1 is installed, when the structural member of the passenger conveying apparatus 1 is installed, there is a possibility that the descending entrance 7 is more likely than when the camera is directly installed in the building. The shooting range in and around it is limited, that is, it is impossible to shoot the range farther from the downstairs entrance. Therefore, in order to make up for this disadvantage, the computing unit 32 of the passenger conveying apparatus 1 and the operation control system 100 of the present embodiment uses the passenger density and the passenger speed detected based on the imaging data of the escalator side camera 14 as described above, and detects the The unit 34 determines the congestion situation based on the occupancy rate detected by the inverter load information. Thereby, even if a camera is not installed directly in a building, it is possible to accurately determine a crowded situation.

In addition, in the present embodiment, as threshold values corresponding to the passenger density, passenger speed, and occupancy rate, two types of threshold values corresponding to the degree of congestion are set, and the control unit 11 can determine abnormality (congestion) or slight abnormality (slightly abnormality). crowded) as a crowded condition. Furthermore, the control unit 11 stops the passenger conveying device 1 when it is determined that the crowded situation is abnormal (congested), and stops the passenger conveying device 1 when it is determined that the crowded situation is slightly abnormal (slightly crowded). slow down. As described above, the control unit 11 can appropriately control the operation of the passenger conveyance apparatus 1 according to the crowded situation.

In addition, a part of the structure of a certain embodiment example can be replaced with the structure of another embodiment example. In addition, the structure of another embodiment example can also be added to the structure of a certain embodiment example. In addition, addition, deletion, and replacement of other structures can also be performed with respect to a part of the structures of the respective embodiments.

In addition, each of the above-described structures, functions, processing units, processing means, and the like may be implemented in hardware by, for example, designing a part or all of them in an integrated circuit. In addition, each of the above-described structures, functions, and the like can also be implemented in software by a processor interpreting and executing a program that implements the respective functions. Information such as programs, tables, and files that realize each function can be placed in a recording device such as a memory, a hard disk, and an SSD (Solid State Drive), or a recording medium such as an IC card, SD card, and DVD.

In addition, a control line and an information line show the part considered to be necessary for description, and do not necessarily show all control lines and information lines on a product. In fact, it can also be considered that almost all structures are connected to each other.

Furthermore, in this specification, the processing steps describing time-series processing naturally include not only processing performed in time series in the order described, but also processing performed in parallel or individually (for example, parallel processing or object-based processing), although It does not have to be processed in time series.

In addition, in this embodiment, the passenger conveyance apparatus 1 demonstrated the form which moves a passenger in the direction shown by the hollow arrow in FIG. 1, ie, the form which moves a passenger from the upper floor to the lower floor. However, the present invention can also be applied to a passenger conveying apparatus that moves passengers from a lower deck to an upper deck, and an operation control system of the passenger conveying apparatus. In this case, in the example shown in FIG. 1 , the signal unit 31 detects the passenger density and the passenger speed based on the imaging data of the elevator entrance side camera 13 .

In addition, in the present embodiment, the method in which the detection unit 34 detects the occupancy rate based on the inverter load information has been described. However, instead of this, the occupancy rate may be detected based on the load (load) measured by the load meter provided under the casing of the passenger conveying apparatus 1 and the load allowed by the passenger conveying apparatus 1 set in advance. In addition, the occupancy rate may be detected based on the number of passengers and a preset maximum number of passengers by infrared sensors provided in the ascending entrance 6 and the descending entrance 7 (see FIG. 1 ).

In addition, it is also possible to determine that the same passenger has boarded while moving from the elevator entrance 6 to the descending entrance 7 of the passenger conveyor 1 based on the imaging data of the elevator entrance side camera 13 and the imaging data of the descending entrance side camera 14 . The occupancy rate is detected based on the number of passengers in the passenger conveyance apparatus 1 based on the determined number of passengers and a preset maximum number of passengers. In this case, the image of the passenger is extracted from the imaged data of the camera 13 on the escalator side and the imaged data of the camera 14 on the side of the stairway, and it is determined whether it is the same passenger based on the similarity of the extracted images. Then, when it can be determined that they are the same passenger, the images captured by the elevator entrance side camera 13 from the time of acquiring the imaging data of the elevator entrance side camera 13 to the time of acquiring the imaging data of the descending entrance side camera 14 Images of passengers are extracted from the data, and the number of passengers who have boarded the passenger conveying apparatus 1 during the period when the same passenger moves from the ascending gate 6 to the descending gate 7 of the passenger conveying apparatus 1 is specified. By doing so, it is possible to perform appropriate operation control even in a passenger conveying apparatus not provided with an inverter.

In addition, in this embodiment, the CPU21 of the control part 11 has demonstrated the form which functions as the signal part 31, the calculation part 32, and the detection part 34 by executing the program memorize|stored in the ROM22. However, instead, a circuit having its own function, such as an ASIC (application specific integrated circuit), may be used for each of the signal unit 31 , the arithmetic unit 32 , and the detection unit 34 .

In addition, in the present embodiment, the mode of attaching the upper-deck side camera 13 and the lower-deck side camera 14 to the structural member of the passenger conveying apparatus 1 has been described. However, two or any one of these cameras may also be installed in the building.
