JPH11263574A - Operating speed automatic regulating device for passenger conveyor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To automatically regulate the operation speed to a speed suitable for the aged and children considered to be relatively short by regulating the operation speed on the basis of the output signal of a means for judging the height of a passenger provided near the platform of a passenger conveyor. SOLUTION: This device is provided with a human body detecting means 2 having a detection range A1 detectable of a tall person of about adult, and a human body detecting means 3 having a detection range A2 detectable of a relatively short person as the aged and children. When a grown-up passenger utilizes a passenger conveyor, since the passenger approaches the detection ranges A1, A2, and both the detecting means 2, 3 detect the passenger, the passenger conveyor performs a general operation. When a relatively short person as the aged or child, since only the human body detecting means 3 detects the passenger, a speed switching signal is outputted form an output circuit, and the operation speed of the passenger conveyor is switched to a relatively slow prescribed speed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor for automatically adjusting a driving speed of a passenger conveyor to an appropriate driving speed by a passenger.

[0002]

2. Description of the Related Art A conventional passenger conveyor is operated at a predetermined constant speed regardless of passengers during operation. For this reason, when the passengers are elderly and children, the driving speed of the passenger conveyor is too fast or inappropriate, so that there is a problem that anxiety is given during the time from getting on to getting off.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-mentioned problems and to automatically provide appropriate driving when passengers on a passenger conveyor are elderly and children who are considered to be relatively short. It is to provide a passenger conveyor that adjusts to the speed.

[0004]

In order to achieve the above object, the present invention provides means for determining the height of a passenger near a landing of a passenger conveyor, and outputs an output signal of the means for determining the height of the passenger. Originally, the driving speed is automatically adjusted without manual operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG.

In FIG. 1, 1 is a passenger conveyor, 2 is a human body detecting means 1, 3 is a human body detecting means 2, and 2 and 3 have different detection ranges. Reference numeral 4 denotes a passenger guiding means such as a handrail for guiding a passenger into the detection ranges 2 and 3.

The human body detection means 2 has a detection range A1 which can detect a person of the height of an adult but cannot detect a person of a relatively short height such as an elderly person and a child. A person with a relatively short height such as a child has a detection range A2 that can be detected, but a person with a height of about an adult cannot detect.

FIG. 2 is a block diagram showing an automatic switching operation of the passenger conveyor according to one embodiment of the present invention. From FIG.
Reference numeral 5 denotes a human body detection circuit 1 corresponding to the above 2, 2 denotes a human body detection circuit 2 corresponding to the above 3, 7 denotes an inverting circuit for inverting the logic of the above 5, and 8 denotes an output signal of the above 7 An output circuit for outputting a logical product of the six output signals.

The operation will be described with reference to FIGS. 1 and 2. When there is no passenger, there is no detection target in the detection ranges A1 and A2, and both the human body detecting means 2 and 3 detect a passenger. As a result, the passenger conveyor operates at a normal driving speed because the output 5 does not generate a speed changeover signal because the 5 and 6 do not generate an output.

When an adult passenger intends to use the passenger conveyor, the passenger enters the detection range of the previous period A1 and A2, and both 2 and 3 detect the passenger. As a result, the passenger conveyor operates normally because the vehicle does not output the speed switching signal.

When a relatively short person, such as an old man or a child, uses the vehicle, the passenger has no detection target in the detection range of the previous period A1, and the passenger enters only the detection range of the previous period A2. Does not detect a passenger, only the first quarter 3 detects a passenger, so no output is generated in the first half 5 and only an output is generated in the first six, and as a result, the aforementioned 8 outputs a speed switching signal and outputs The operation speed of the passenger conveyor can be switched to a predetermined speed.

FIG. 3 is a block diagram of another embodiment of the present invention, which is an automatic driving passenger conveyor which waits without driving when there is no passenger and drives when there is a passenger.

As shown in FIG. 3, when there is no passenger, there is no detection target in the detection ranges A1 and A2, and neither the human body detecting means 2 nor 3 detects a passenger.
9 and 10 do not produce an output, so that 1
The elevators 2 and 13 do not output a start signal, so that the elevator does not start.

When an adult passenger intends to use the passenger conveyor, the passenger enters the detection range of the previous period A1, and the above 2 detects the passenger, so that the above 9 generates an output, and as a result, the above 13 period is output. Does not generate an output, the 12 outputs a normal operation speed start signal, and the passenger conveyor starts operating at a normal operation speed.

When a relatively short person, such as an old man or a child, uses the vehicle, the passenger has no detection target in the detection range of the previous period A1, and the passenger enters only the detection range of the previous period A2. Does not detect a passenger, only the first quarter 3 detects a passenger, so no output is generated in the first nine, only an output is generated in the first ten, as a result, no output is generated in the first half 12, and By outputting a speed switching start signal, the passenger conveyor starts operating at a predetermined speed different from the normal operation speed.

[0016]

According to the present invention, means for judging the height of a passenger is provided near the landing of the passenger conveyor, and the operation speed of the passenger conveyor is manually adjusted based on the output signal of the means for judging the height of the passenger. There is an effect that the adjustment can be performed automatically regardless of the above.
