As a result, it is possible to obtain a welfare-compatible passenger conveyor that does not lower the service for people with reduced walking ability.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of an escalator as a passenger conveyor according to the present invention will be described below with reference to FIGS. FIG. 1 is a schematic side view showing the entire escalator, FIG. 2 is a block diagram for detecting a moving speed of a passenger traveling from a platform provided at an entrance to a tread, and issuing a speed command to the tread corresponding to the detected speed. 7A and 7B are diagrams illustrating an example of recognizing a moving speed of a passenger by a passenger moving speed detecting device, in which FIG. 7A illustrates an example of recognizing a moving speed of a normal healthy person, and FIG.
[0009]
The escalator 1 is connected endlessly to a frame 4 installed over the upper floor 2 and the lower floor 3, and guides a step 5 that circulates at a rated speed of, for example, 30 m / min. A balustrade 6 is erected on the frame 4 on both sides in the moving direction of the step 5 connected endlessly, and a moving handrail 7 that moves in synchronization with the step 5 is guided around the balustrade 6. . The step 5 has a step board on which a passenger rides.
[0010]
In the upper part of the upper and lower ends of the frame body 4, floors 8 and 9 are respectively installed to form entrances for getting on and off the steps 5. Vertical columns 10, 11 and 12, 13 are erected near the entrance. The vertical columns 10 and 12 are installed at positions away from the steps 5, and the vertical columns 11 and 13 are installed at positions approaching the steps 5 at the same intervals L from the vertical columns 10 and 12, respectively. Each of the columns 10 to 13 is provided in a pair.
[0011]
Although illustration is simplified, the vertical pillars 10 and 12 are provided with, for example, phototube-type passenger detection devices 14D and 14U for detecting a passenger approaching to get on the step 5.
[0012]
Further, the vertical columns 10 and 12 are equipped with, for example, a photoelectric type passenger moving speed detection device 15D and 15U for detecting the moving speed of the passenger, and the vertical columns 11 and 13 also detect the moving speed of the passenger, for example, a photoelectric type. Passenger movement speed detection devices 16D and 16U are provided. Of the passenger moving speed detectors 15D, 15U, 16D, and 16U, the passenger moving speed detectors 15D and 16D and the passenger moving speed detectors 15U and 16U measure the moving time of the passenger to detect the moving speed. It is.
[0013]
A computing means 17 is provided in the frame 4, and the computing means 17 receives signals from the passenger traveling speed detecting devices 15D, 15U and 16D, 16U to determine the traveling speed of the step 5. You have set. The set moving speed is instructed via a control device 18 to a driving machine M for driving the step 5. The control device 18 receives the passenger detection signals from the passenger detection devices 14D and 14U, drives the driving machine M, and also drives the stopped steps 5.
[0014]
In the above configuration, the passenger moving speed detecting devices 15D and 15U are first speed detecting devices, and the passenger moving speed detecting devices 16D and 16U are second speed detecting devices.
[0015]
In the above configuration, when the passenger approaches to move to the upper floor (lower floor) from the entrance (lower floor) below (above) the escalator 1, the passenger detection device 14D (14U) and the passenger movement speed detection device 15D (15U) Detects passengers.
[0016]
As described above, the passenger detection device 14D (14U) that has detected the passenger issues the passenger detection signal to the control device 18 and moves the step 5 in the ascending direction (downward direction) with respect to the driving machine M in the stopped state. To drive the steps 5 at a low speed (for example, 20 m / min) in the ascending direction (downward direction).
[0017]
On the other hand, when the passenger detected by the passenger moving speed detecting device 15D (15U) is detected by the passenger moving speed detecting device 16D (16U), the passenger is measured by the passenger moving speed detecting devices 15D (15U) and 16D (16U). The calculation means 11 calculates the moving speed of the passenger. The moving speed of the step 5 is determined based on the calculation result, and the determined moving speed is transmitted to the control device 18 to accelerate or decelerate the driving machine M.
[0018]
The passenger moving speed detecting devices 15D (15U) and 16D (16U) are set at an interval L of, for example, 1.0 m, and after detecting the passenger by the passenger moving speed detecting device 15D (15U), the passenger moving speed detecting device 15D (15U) detects the passenger. The time required for detection by the device 16D (16U) is measured by the calculating means 17. For this time, for example, 1.5 m / sec, which is a standard walking speed of a normal healthy person, is set as a reference passenger moving speed, and whether the passenger moving speed measured from the reference passenger moving speed is low or high is calculated. The calculation is further performed by the means 17, and the calculation result is transmitted to the control device 18 to drive the driving machine M to further accelerate or decelerate the step 5 moving at a low speed (20 m / min).
[0019]
To explain this with reference to FIG. 2, the moving speed of the passenger is calculated by the calculating means 17 based on the detection signals from the passenger moving speed detecting devices 15D (15U) and 16D (16U), and this is calculated as the reference passenger moving speed. The moving speed of the step 5 is determined by comparison. The determined moving speed is instructed to the driving machine M via the control device 18 to change the speed of the driving machine M.
[0020]
As shown in FIG. 3 (a), the calculation by the calculating means 17 sets the operation time (detection) of the passenger moving speed detecting device 15D (15U) to 0 seconds in the case of the moving speed of a general healthy person. Thereafter, a model is based on a model in which it takes 1.5 seconds to walk during the interval L = 1.0 m from there to the passenger moving speed detecting device 16D (16U). Then, as shown in FIG. 3 (b), in the case of the moving speed of the person with reduced walking ability, when it is determined that it took three seconds to walk between the intervals L = 1.0 m, Is judged as a person with reduced walking ability. If it is determined that the passenger is a person with reduced walking ability, the movement of the steps 5 is temporarily stopped and the driving is resumed at a rated speed of 30 m / min or lower. Alternatively, by performing continuous operation at a moving speed of, for example, 20 m / min, which is lower than the rated speed of 30 m / min, a control configuration of an optimum speed that can contribute to the safety of the weak, particularly to the prevention of a fall accident. Conversely, if the passing time between the intervals L is 1.5 seconds or less than 1.5 seconds, there is a risk of a fall accident even at a driving speed of 20 m / min or more, which is driven by the command of the passenger detection device 14D (14U). Is determined to be missing. Therefore, for example, the speed is converted to a rated speed or a higher speed of 45 m / min, and a service that can arrive at the destination floor quickly, that is, a high-speed optimal speed control configuration is adopted.
