[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a passenger conveyor such as an escalator and an electric road, and more particularly, to a passenger conveyor suitable for detecting a passenger and automatically driving the passenger conveyor.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known an apparatus that automatically detects the presence or absence of a passenger using an escalator and automatically starts and stops the escalator. For example, in Japanese Patent Publication No. 2569242, a first detection device that detects the passage of a passenger is disposed at a gate far from a movable part of an escalator, and is located near the movable part of the escalator at the gate. A second detection device for detecting the passage of the passenger is disposed at the position, and a third detection device for detecting the passage of the passenger is disposed at a position near the escalator movable portion at the exit of the escalator, and the first detection device is provided. It has been proposed that the operation of the escalator is started by the detection signal of (1), the operation is continued for a predetermined time by the detection signal of the second detection device, and the operation of the escalator is stopped by the detection signal of the third detection device.
[0003]
Further, Japanese Patent Publication No. 2569192 proposes a device in which a detection device similar to the first and second detection devices described above is provided and an escalator is controlled by a combination of the detection signals.
[0004]
[Problems to be solved by the invention]
According to the escalator described in the former of the prior art (Patent No. 2569242), when a single passenger uses the escalator, there is no wasted time and power saving is excellent. As described above, no consideration is given to the inconvenience that occurs when a plurality of passengers use the vehicle consecutively. The same is true of the latter (Patent No. 2569192) in that such disadvantages are not considered.
[0005]
That is, when a plurality of passengers use the vehicle consecutively, two or more passengers may pass through the detection device in an overlapping state. In such a case, the detection device detects the passage as a single person, but when passing through another detection device, the overlap is eliminated and an inconvenience occurs when there is an interval. For example, assume that three passengers get on the escalator in succession and pass through the second detection device with the second and third passengers overlapping. In this case, the first and second detectors detect the first passenger, and the escalator starts operating for a predetermined time, and then the third detector can confirm the passage of the first passenger. However, since the second detection device detects the second and third passengers as one, after the second and third passengers pass through the second detection device, they leave before reaching the exit. If the third passenger detects the passage of the second passenger, the third detection device outputs a stop command to the escalator even though the third passenger is on the escalator. There are inconveniences. At that time, when a new passenger passes through the first detection device, there is a disadvantage that the escalator is activated again.
[0006]
An object of the present invention is to provide, upon automatic shutdown of the passenger conveyor by detecting the passengers getting on and off, to eliminate a disadvantage such as described above, for example, a passenger passing through overlap away in the middle Another object of the present invention is to operate the vehicle safely even if a plurality of passengers continuously get on the passenger conveyor by continuing to drive until the rear passenger gets off .
[0007]
[Means for Solving the Problems]
In order to solve the above problems, a passenger conveyor according to the present invention includes a transport unit that transports passengers, a detection device that is provided near entrances at both ends of the transport unit, that detects passage of a passenger, and a detection device that detects the detection device. In a passenger conveyor comprising a control device for automatically stopping the operation of the transport unit based on the signal, the detection device is located at a position near the transport unit end of the entrance at both ends of the transport unit, and the transport unit from this position. Are respectively disposed at positions away from each other on the opposite side, and the control device sequentially sets the detection devices as first to fourth detection devices from the entrance side along the transport direction of the transport unit, and the first detection device of the operation command of the transport unit outputs the first setting time each time a detection signal is input, each time the detection signal of the second detecting device is input, together with you undo the first set time, The operation command of the transport unit is output for a second set time. Each time a detection signal of the third detection device is entered, together with you undo the second set time, the operation command of the transport unit outputs the third set time, the detection signal of the fourth detection device The stop command of the transport unit is output every time the input is performed, and the first to third set times are required for the passenger to move from the position of each detection device to the position of the fourth detection device. It is basically set based on time .
[0008]
In this way, even if two people pass through the first detection device in an overlapping manner and then pass through the second detection device at intervals, the passengers who have passed through the second detection device later will be referred to. Since the operation time of the passenger conveyor is reset, the operation is continued until the later passenger gets off the passenger conveyor. In other words, even when a plurality of passengers get on continuously, the driving time is finally determined at the time when the last passing passenger is detected, so that the vehicle does not stop while riding. The same applies to the case where two persons pass through the second and third detection devices in an overlapping manner and then pass through the third and fourth detection devices at intervals.
[0009]
Further, the third detection device is made effective after a fourth set time has elapsed since the detection signal of the second detection device was input, and the fourth set time is determined by the position of the second detection device. It is preferable that the time is set to be equal to or slightly shorter than the time required for the passenger to move from to the position of the third detection device. According to this, after two or more passengers pass over the second detection device, some passengers go up the escalator quickly, so that the distance between the passengers is greatly separated, and the preceding passengers Even if the vehicle sequentially passes through the third detection device and the fourth detection device, the third detection device does not become effective, and the escalator stop command is not output from the fourth detection device. You can reach the exit.
[0010]
In addition, the fourth detection device is enabled after a fifth set time has elapsed after the detection signal of the third detection device is input, and the fifth set time is determined by the position of the third detection device. It is preferable to set the time to be equal to or slightly shorter than the time required for the passenger to move from to the position of the fourth detection device. According to this, as in the case described above, even if some passengers pass through the third and fourth detection devices at an early stage, the stop command of the escalator is not output from the fourth detection device, and the third and earlier detection devices are not output. Will be stopped in accordance with the operation time by the detection device of, and the following passenger can safely reach the exit.
[0011]
The first to fourth detection devices that detect the passage of a passenger are photoelectric beam type detection devices that detect the passage of a passenger by irradiating a light beam on a passage of the passenger and blocking the light beam by the passenger. Or, a well-known passenger passage detection device such as a detection device using an energy beam instead of the light beam can be applied.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a passenger conveyor to which the present invention is applied will be described with reference to FIGS. FIG. 1 is a side view showing a schematic configuration of an escalator according to an embodiment to which the present invention is applied. FIG. 2 is a flowchart showing a control operation of the escalator control device of the embodiment in FIG.
[0013]
As shown in FIG. 1, the escalator 3 has an entrance / exit 2 located on the lower floor and an entrance / exit 3 located on the upper floor. A corresponding plurality of steps 4 are connected and movably arranged, and handrails 5 that move in synchronization with the steps 4 are guided and supported by a balustrade 6 on both sides where the steps 4 move.
[0014]
A pillar 7 is provided in the passenger passage on the opposite side of the step 2 from the entrance 2 on the lower floor, and the pillar 7 is provided with a first detection device 8 for detecting the passage of a passenger. The position of the first detection device 8 is apart from the reversing part of the handrail 5 by a distance L (for example, 1.5 to 2.0 m). Further, a second detecting means for detecting the passage of a passenger near the balustrade 6 at a position closer to the first detecting device 8 than the end of the step 4 by a distance S1 on the step 4 side from the first detecting device 8. Is provided. On the other hand, the third detection device 10 is also provided near the balustrade 6 at a position separated from the end of the step 4 by a distance S2 toward the opposite side of the step from the entrance 3 of the upper floor. And the support | pillar 12 is provided in the position further away from the position of the 3rd detection apparatus, ie, the distance L (for example, 1.5-2.0 m) away from the end of the step 4, on the side opposite to the step. The column 12 is provided with a fourth detection device 11. An operation control device 13 that controls the operation and stop of the escalator based on the detection signals of these detection devices 8, 9, 10, and 11 is installed in a machine room formed below the entrance 3.
[0015]
Next, the operation of the escalator of FIG. 1 will be described with reference to the flowchart of FIG. Here, an example in which the elevator of FIG. 1 is driven to move in one direction from the lower floor side to the upper floor side will be described. First, when a passenger walks toward the entrance 2 on the entrance side and passes the position of the first detection device 8, a first detection signal indicating that the passenger has passed from the first detection device is driven. Output to the control device 13.
[0016]
The operation control device 13 starts the control in response to the input of the first detection signal (S11), outputs an operation command to the escalator, and simultaneously starts measuring a first set time T1 (S12). Thus, the escalator is activated. The first set time T1 is set to a time obtained by adding a margin to the time required for a passenger to pass from the first detection device 8 to pass through the fourth detection device 11. That is, the time A from the first detection device 8 to the second detection device 9, the time B from the second detection device 9 to the third detection device 10, the third detection device 10 T1 = (A + B + C + α) by adding the time C from the time of the detection to the fourth detection device 11 and the margin time α. When a plurality of passengers use the vehicle continuously, the setting time T1 is sequentially reset, and as a result, the time from when the last passing passenger is detected becomes the final setting time T1.
[0017]
Next, it is determined whether or not the passenger has passed through the second detection device 9 based on the presence or absence of the input of the second detection signal (S13). If the determination is affirmative (YES), the process proceeds to step 14, in which an operation command is continuously output to the escalator, and at the same time, the first set time T1 is canceled, and the timing of the second operation time T2 is started. Here, T2 is set to the time required for a passenger to pass from the second detection device 9 to pass through the fourth detection device 11, plus some extra time. That is, T2 = (B + C + α) is set. Thereby, the operation of the escalator is continued. The set time T2 also becomes the final set time T2 from the time when the last passing passenger is detected, similarly to the above-described T1.
[0018]
As described above, when the escalator is driven for a sufficient set time T1 required for the passenger to reach the exit when passing through the first detection device 8, the escalator is driven by the first detection device 8. Later, even if the user gets absorbed in the story and gets on the steps 4 slightly behind, the disadvantage of stopping halfway can be avoided. In particular, since the set time T1 is canceled when the vehicle passes through the second detection device 9, and the new set time T2 is set again, it is possible to prevent a problem that the vehicle stops on the way while moving on the steps 4.
[0019]
On the other hand, if the determination in step S13 is negative (NO), the process proceeds to step S31 to determine whether or not the time T1 has elapsed. If the determination is affirmative (YES), a stop command is output to stop the escalator ( S32) If negative (NO), the process returns to step S12. Accordingly, it is possible to cope with a case where the passenger returns after passing through the first detection device 8 without getting on the escalator.
[0020]
After the process at the time of passing through the second detection device 9, in step S15, it is determined whether or not the measured time of the operation time T2 has reached the fourth set time T4. The detection operation of the device 10 is enabled (S16). Here, T4 is set equal to or slightly shorter than B. That is, normally, the detection signal of the third detection device 10 is made valid at a time when it is considered to pass through the third detection device 10. Next, in step S17, it is determined whether or not the signal has passed through the third detection device 10 based on whether or not the third detection signal has been input. If the determination is affirmative (YES), the process proceeds to step S18, where the escalator is operated. At the same time, the second set time T2 is canceled, and the measurement of the third drive time T3 is started. Here, T3 is set to the time required for a passenger to pass from the third detection device 10 to pass through the fourth detection device 11 plus some extra time. That is, T3 = (C + α) is set. The set time T3 also becomes the final set time T3 from the time when the last passing passenger is detected, similarly to the above T1 or T2.
[0021]
The period during which the third detection device is enabled is set to a period until the escalator stops. By setting in this manner, the third passenger 10 can detect the last passenger, and after passing through the second detector 9, the passenger steps on or returns on the step 4. , Can be detected even if the passage through the third detection device 10 is delayed.
[0022]
Next, in step S19, it is determined whether or not the measured time of the operation time T3 has reached the fifth set time T5, and when it has reached, the fourth detection device 11 is enabled (S20). Here, T5 is set to a value equal to or slightly shorter than C. That is, the detection operation of the fourth detection device 11 is made effective at a time when it is considered that the light passes through the fourth detection device 11 under normal circumstances. Next, in step S21, it is determined whether or not the signal has passed the fourth detection device 11 based on whether or not the fourth detection signal has been input. If the determination is affirmative (YES), the process proceeds to step S22. Output a stop command to stop the escalator.
[0023]
On the other hand, if the determinations in step S17 and step S21 are negative (NO), the process proceeds to steps S33 and S34, respectively, and when the set time T2 or T3 has elapsed, the process proceeds to step S22 to stop the escalator.
[0024]
As described above, the present embodiment has the following effects.
(1) Even if a passenger stops before the second detection device 9 and the entry to the step 4 is delayed, if the vehicle passes through the second detection device 9, the set driving time is updated. Therefore, the operation of the escalator continues to reach the exit. As a result, it is possible to prevent inconvenience such as stopping during the movement on the steps 4.
[0025]
(2) Even if the driver passes through the third detector 10 after stepping on the step 4 and stepping or returning, delaying the passage of the third detector 10 will update the set time for driving. The operation of the escalator continues until the vehicle descends securely, and it is possible to prevent inconveniences such as stopping while moving on the steps 4.
[0026]
(3) Since the escalator is stopped after the third detection device 10 is activated and the fourth detection device 11 is further activated, the escalator is stopped when the passenger reaches the exit. Since the vehicle can be stopped reliably, it is possible to achieve a safe, highly efficient power-saving effect with reduced useless idle time.
[0027]
As the detection device in the above embodiment, a photoelectric beam type or an energy ray application type is optimal, but a known detection device instead of these can be applied as it is.
[0028]
Further, although not described in the above embodiment, when the escalator is in the stopped state, and the passenger passes through the fourth detection device 11 in order to get in from the exit side in the opposite direction to the predetermined moving direction, the escalator Can be driven in a predetermined moving direction for a predetermined time (for example, 10 to 30 seconds) to add a function of notifying a passenger that he or she cannot get in.
[0029]
Further, in the above embodiment, the case of moving from the lower floor to the upper floor has been described as an example. However, it is easily understood by those skilled in the art that the same can be applied to the case of the opposite moving direction. Is clear. That is, when moving from the upper floor to the lower floor, the fourth detector 11 is the first detector, the third detector 10 is the second detector, and the second detector 9 is the second detector. By replacing the third detecting device and the first detecting device 8 with the fourth detecting device, the present invention can be applied as it is.
[0030]
【The invention's effect】
As described above, according to the present invention, even when a plurality of passengers continuously get on the passenger conveyor, they can be operated safely and have an effect of power saving.
