  However, in the above-described escalator control device, the following points are not considered.

  When the escalator is crowded with escalator users, there are a large number of escalator users at the escalator platform with the front and back spaces being closed. For this reason, it is conceivable that a plurality of photoelectric switches of the wheelchair detection device are stepped on simultaneously by a plurality of escalator users, and all the photoelectric switches are simultaneously detected. Then, even though there is no wheelchair user at the escalator platform, the escalator control device erroneously detects that there is a wheelchair user at the escalator platform, and the escalator operation mode is switched to the wheelchair operation mode.

  If the escalator operation mode is switched to the wheelchair operation mode when the escalator is congested, the wheelchair step is deformed and the escalator is temporarily stopped at the position where the wheelchair step faces the escalator platform. The result is a spur.

  The present invention has been made to solve such a problem, and the purpose thereof is a passenger who can prevent the occurrence of a false detection that there is a wheelchair user even though there is no wheelchair user at the escalator platform. It is to provide a conveyor control device and a passenger conveyor.

  A first feature according to an embodiment of the present invention is that, in the passenger conveyor control device, between a first detection unit that detects a wheelchair user at the passenger conveyor platform and a step of circulating movement with the passenger conveyor platform. A passenger conveyor user at the passenger conveyor platform is a wheelchair user based on a second detection unit that detects a passenger conveyor user in the vehicle, a detection result of the first detection unit, and a detection result of the second detection unit. And means for switching the operation mode to the wheelchair operation mode when it is determined that the conveyor user at the passenger conveyor landing is a wheelchair user.

  The 2nd characteristic concerning an embodiment of the invention is provided with a passenger conveyor control device concerning the 1st characteristic in a passenger conveyor.

  According to the present invention, it is possible to accurately determine whether the escalator user at the passenger conveyor landing is a wheelchair user based on the detection result of the first detection unit and the detection result of the second detection unit. In the case where there is no wheelchair user at the passenger conveyor platform, it is possible to reliably prevent erroneous switching to the wheelchair operation mode.

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

  As shown in FIGS. 1 and 2, an escalator 1 that is a passenger conveyor according to an embodiment of the present invention is a step that is a plurality of steps that circulate and engage with an endless chain (not shown). 2, a pair of escalator frames 3 disposed on both sides in the moving direction of the step 2, and a pair of balustrades 4 erected on the escalator frame 3. A handrail belt 5 that moves in synchronization with the step 2 is provided on the outer periphery of the balustrade 4.

  The escalator 1 has a function of placing the wheelchair user A on the step 2, and when the wheelchair user A is placed on the step 2, an elevating mechanism (not shown) among the plurality of steps 2. The specific step 2 connected to the base is raised, and, for example, three consecutive steps 2 are transformed into a wheelchair-specific step located on the same horizontal plane.

  An escalator landing 6 as a passenger conveyor landing is provided at one end side in the circulation direction of the step 2, and an escalator landing (not shown) as a passenger conveyor landing is provided at the other end side in the circulation direction of the step 2. ing. The escalator landing 6 and the escalator landing are the same structure, and can be switched by reversing the circulation direction of the steps 2.

  The escalator platform 6 is provided with a first detection unit 7 that detects a wheelchair user A at the escalator platform 6. Furthermore, on the escalator platform 6 side, a second detection unit 8 that detects a general escalator user who is a general passenger conveyor user between the escalator platform 6 and the step 2 that circulates, and a wheelchair dedicated step And a third detection unit 9 disposed at a position for detecting a wheelchair user who has boarded the vehicle.

  As the first detection unit 7, a pressure detection unit such as a mat switch or a piezoelectric sensor is used. The pressure detector 7 is disposed on a boarding / alighting plate 10 provided at the escalator landing 6. A lead wire (not shown) connected to the pressure detection unit 7 can be wired in a slip-preventing recess formed in the boarding / alighting plate 10, and the escalator user who has the lead on the boarding / alighting plate 10 It is possible to prevent disconnection due to being stepped on.

  The pressure detection unit 7 is arranged according to the pitch “P” between the front and rear wheels of the wheelchair conforming to the JIS standard, and the wheel width “W” of the left and right front wheels and the rear wheel. When the person A comes, it is arranged at a position where pressure is simultaneously received from the front wheel and the rear wheel of the wheelchair. For this reason, when the wheelchair on which the wheelchair user A rides comes to the escalator landing 6, pressure acts on the four pressure detection units 7 from the front wheels and the rear wheels, and the four pressure detection units 7 are simultaneously in a detection state.

  In this embodiment, the case where the pressure detection unit 7 is used as the first detection unit 7 has been described as an example. However, instead of the pressure detection unit 7, a wheelchair of a wheelchair user who has come to the escalator landing 6 is used. You may use the several photoelectric sensor arrange | positioned with the space | interval detected simultaneously. The position where the photoelectric sensor is provided in this case is preferably the escalator landing 6 or a position toward the escalator landing 6 where the wheelchair on which the wheelchair user A is riding can be detected from the side. The photoelectric sensor may be either a reflection type or a transmission type.

  As the 2nd detection part 8, the photoelectric sensor arrange | positioned in the horizontal direction which cross | intersects the direction where an escalator user moves on the step 2 from the passenger conveyor landing 6 is used. The photoelectric sensor 8 can be either a reflection type or a transmission type. When the reflective photoelectric sensor 8 is used, the photoelectric sensors 8 each including a light emitting unit and a light receiving unit are provided on the pair of escalator frames 3. When the transmissive photoelectric sensor 8 is used, a light emitting part is provided on one escalator frame 3, a light receiving part is provided on the other escalator frame 3, and the light emitting part and the light receiving part are arranged on a straight line.

  As the third detection unit 9, two pairs of transmission type photoelectric sensors arranged in a horizontal direction intersecting the moving direction of the step 2 are used. Two pairs of photoelectric sensors 9 are provided in front of the comb 11 of the belt conveyor platform 6 along the moving direction of the step 2, and two sets of the light emitting unit 9 a and the light receiving unit 9 b include a front wheel and a rear wheel of the wheelchair. The escalator frame 3 is provided with an interval that matches the pitch “P”. When the wheelchair on which the wheelchair user A rides gets on the wheelchair dedicated step, the front wheel and the rear wheel of the wheelchair are simultaneously detected by the photoelectric sensor 9.

  The escalator 1 is provided with a driving electric circuit as shown in FIG. This electric circuit for driving is for driving a motor 12 that drives the step 2 and the handrail belt 5, and an inverter device 13 and a power regeneration unit 14 are provided between the motor 12 and the power source side. . The inverter device 13 is a device for adjusting the number of revolutions of the motor 12, and the power regeneration unit 14 is a device for regenerating energy generated when the escalator 1 descends to the power source. Further, a noise filter 15 and a reactor 16 are provided between the motor 12 and the power supply as a countermeasure against high frequency.

  A control device 17 that outputs signals to the inverter device 13 and the power regeneration unit 14 is provided. A first detection unit (pressure detection unit) 7, a second detection unit (photoelectric sensor) 8, and a third detection unit (photoelectric sensor) 9 are connected to the control device 17. The control device 17 outputs a belt conveyor operation speed signal to the inverter device 13, and the inverter device 13 supplies a frequency voltage corresponding to the belt conveyor operation speed signal to the motor 12.

  As shown in FIG. 1, the motor 12, the control device 17, the inverter device 13, the power regeneration unit 14, the noise filter 15, and the reactor 16 are escalator pits 18 provided below the boarding board 10. It is stored inside.

  The control device 17 is a microcomputer including a CPU, a ROM, and a RAM, and is stored in the ROM based on the detection results of the first detection unit 7, the second detection unit 8, and the third detection unit 9. Control according to the program.

  The control by the control device 17 is performed as shown in FIG. During the operation of the escalator 1, it is determined whether or not all the first detection units (four pressure detection units) 7 have simultaneously detected pressure for a certain fixed time (for example, 2 seconds) (S1). As for the case where all of the first detectors (four pressure detectors) 7 installed in the escalator landing 6 simultaneously detect pressure for 2 seconds or more, the case where the wheelchair user A comes to the escalator landing 6 and the escalator 1 There may be a case where there are a large number of escalator users in the escalator platform 6 with the front and rear intervals being filled due to congestion or the like.

  When all of the first detection units (four pressure detection units) 7 simultaneously detect pressure for 2 seconds or more (YES in S1), the second detection unit (photoelectric sensor) 8 detects the escalator user. It is determined whether or not, for example, whether or not a non-detection time has continued for 2 seconds or more (S2). When the second detection unit (photoelectric sensor) 8 detects an escalator user (YES in S2), it means that there is an escalator user moving from the escalator landing 6 toward the step 2, and the escalator 1 It is determined that there is a large number of escalator users at the escalator landing and there is no wheelchair user A at the escalator landing 6, and the process returns to step S1. On the other hand, when the second detection unit (photoelectric sensor) 8 does not detect the escalator user for 2 seconds or longer (NO in S2), it is determined that the wheelchair user A exists at the escalator landing 6. And the escalator user who exists in the escalator landing 6 based on the detection result of the 1st detection part 7 and the detection result of the 2nd detection part 8 by the process of these step S1 and step S2 is the wheelchair user A. A means for determining whether or not is executed.

  When it is determined that the escalator user at the escalator landing 6 is a wheelchair user A (YES in S1, NO in S2), the operation mode of the escalator 1 is switched from the normal operation mode to the wheelchair operation mode (S3). Here, means for switching the operation mode of the escalator 1 to the wheelchair operation mode is executed.

  In addition, the switch to this wheelchair operation mode waits for time until the escalator user arrives at the escalator landing after the 2nd detection part (photoelectric sensor) 8 detects an escalator user last. It is preferred to do so. Thereby, when the escalator 1 stops in order for the wheelchair user A to get into the escalator 1 as described later, it is possible to prevent the escalator user from being left on the stopped escalator 1.

  When the driving mode of the escalator is switched to the wheelchair driving mode, the movement of the step 2 is stopped after the specific step 2 connected to the lifting mechanism passes through the comb 11, and the plurality of sheets are driven by driving the lifting mechanism. The (for example, three) steps 2 are transformed into wheelchair-specific steps located on the same horizontal plane (S4).

  Whether or not a preset time has elapsed since switching to the wheelchair driving mode after switching to the wheelchair driving mode (S5), for example, whether or not 10 seconds after the transformation to the wheelchair dedicated step has ended It is determined whether the third detection unit (photoelectric sensor) 9 has detected a wheelchair user on the wheelchair-only step (S6), and the time set in advance after switching to the wheelchair operation mode is determined here. Means for determining whether or not the third detection unit (photoelectric sensor) 9 has detected a wheelchair user until the time has elapsed.

  If the third detection unit (photoelectric sensor) 9 detects a wheelchair user on the wheelchair dedicated step before the preset time has elapsed (NO in S5, YES in S6), the third detection unit (photoelectric sensor) 9 is on the wheelchair dedicated step. It is determined that the wheelchair user A has boarded, and the escalator 1 is started (S7). Thereafter, control for lowering the wheelchair user A from the escalator 1 at the timing when the wheelchair user A arrives at the escalator landing is performed (S8), and the escalator 1 is switched to the normal operation mode (S9).

  On the other hand, when the preset time has elapsed before the third detection unit (photoelectric sensor) 9 detects the wheelchair user A (NO in S6, YES in S5), the wheelchair user A is on the wheelchair dedicated step. It is determined that an abnormality has occurred when boarding, and an abnormality occurrence signal is output (S10), and means for outputting the abnormality occurrence signal is executed here. When the abnormality occurrence signal is output, the signal is transmitted to a room where the escalator 1 is in charge, and the clerk is informed that an abnormality has occurred at the escalator platform 6. In this case, the escalator 1 is maintained in a stopped state.

  In such a configuration, in the escalator 1, whether or not the wheelchair user A is present at the escalator landing 6 is detected by the detection result of the first detection unit (pressure detection unit) 7 and the detection of the second detection unit (photoelectric sensor) 8. Judgment based on the results. For this reason, when the escalator 1 is crowded and there are many escalator users at the escalator platform 6, even if all the first detection units (pressure detection units) 7 are simultaneously detected by those escalator users, Occurrence of a false detection that the wheelchair user A is at the escalator platform 6 can be prevented.

  Since the first detection unit (pressure detection unit) 7 is disposed on the boarding board 10, the first detection unit (pressure) is used when performing maintenance work by opening the boarding board 10 and entering the escalator pit 18. The detection unit 7 is moved from above the boarding board 10. Thereby, the boarding board 10 can be open | released easily and the operation | work in the escalator pit 18 can be performed easily.

  Moreover, since this escalator 1 is provided with the 3rd detection part (photoelectric sensor) 9, whether the wheelchair user A got on the wheelchair exclusive step | paragraph without abnormality by this 3rd detection part (photoelectric sensor) 9 Can be determined. Thereby, the safety | security in case the wheelchair user A uses the escalator 1 without requiring the assistance of a staff can be improved further.

  In the present embodiment, the case where the present invention is applied to an escalator which is an example of a passenger conveyor has been described as an example. However, the present invention may be applied to other passenger conveyors such as a moving sidewalk. it can.

It is a vertical front view which shows a part of escalator provided with the passenger conveyor control apparatus which concerns on one embodiment of this invention. FIG. It is an electric circuit for driving an escalator. It is a flowchart which shows the control content in case a wheelchair user exists.
