Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a control device for a man conveyor.

[0002]

2. Description of the Related Art A conventional man-conveyor control system includes:
As shown in FIG. 3, all devices were connected to the same control panel. As in the passenger conveyor disclosed in Japanese Patent Application Laid-Open No. 4-189295, there is also an invention in which an operating device is divided and efficiently accommodated, but a power control device such as an inverter device and its regenerative power processing device is divided, and a starting SW is provided. Such signal circuits were centrally connected to the same control panel.

[0003]

Therefore, the wiring between each device is large, and the control panel is large. Also, if a passenger detection device is provided to extend the function of automatically starting and stopping the conveyor, the control panel becomes large,
If the control panel is large, the control panel cannot be provided inside the man conveyor, and it is necessary to enlarge the whole man conveyor or provide a separate machine room.

[0004]

As shown in FIG. 4, since most of the control of the man conveyor is related to the start and stop of the man conveyor, the start and stop of the man conveyor which does not have a problem in safety is operated. An operation panel for controlling a switch to be operated is provided near an operation switch of a man conveyor, and signals are transmitted between control panels for controlling steps by multiplex communication.

[0005] That is to say, this reduces the wiring between the devices, and the control panel also has a small number of functions, so that the size is reduced, and it is not necessary to increase the size of the whole man conveyor. In addition, even when a passenger detection device is provided to extend the function of automatically starting and stopping the man conveyor, a passenger detection panel is provided near the passenger detection device, and signals are transmitted between control panels for controlling steps by multiplex communication. By transmitting the information, the control panel does not become large and it is not necessary to enlarge the whole man conveyor.

[0006]

FIG. 1, FIG. 2, FIG. 3, FIG.
This will be described below.

FIG. 1 is an explanatory view of the overall position of the control device of the man conveyor. In this figure, 1 indicates a man conveyor. Reference numeral 21 denotes a main control panel for controlling steps.
22 is a control panel for lighting the balustrade, 23 is an upper operation panel for operating the start and stop of the man conveyor at the upper part of the man conveyor, 24
Is a lower operation panel for operating the start and stop of the conveyor at the lower part of the conveyor, 25 is a device for detecting passengers from above and an upper passenger detection panel for controlling passenger guide lights, and 26 is for detecting passengers from below. It is a lower passenger detection panel that controls devices and passenger guidance lights.

According to the present invention, as shown in this figure, the control devices are divided and arranged in the vicinity of the respective devices, and the functions are assigned to the respective control panels, thereby reducing the functions of the respective control panels. Reduce the size of the control panel.

FIG. 2 is an explanatory diagram of multiplex communication between control panels. In this figure, reference numeral 30 denotes a multiplex communication line. Each control panel is connected by a multiplex communication line 30. For example, when the conveyor is started, a command signal for starting the conveyor is output from the upper operation panel 23 or the lower operation panel 24 and the multiplex communication line 3 is output.
0 is transmitted to the main control panel 21 and the step starts to be driven. When the conveyor is stopped, a command signal for stopping the conveyor is output from the upper operation panel 23 or the lower operation panel 24, and the main control panel 2 is connected via the multiplex communication line 30.
1 and the step stops driving.

When a passenger from below is detected by the lower passenger detection panel 26, a command signal for starting the man conveyor is output from the lower passenger detection panel 26 and transmitted to the main control panel 21 via the multiplex communication line 30. The step is transmitted and the step starts to be driven. After a certain period of time, a stop command signal for the conveyor is output from the lower passenger detection panel 26, transmitted to the main control panel 21 via the multiplex communication line 30, and the steps are stopped.

At this time, since the start and stop command signals for the man conveyor are transmitted through the multiplex communication line 30, the signals are transmitted not only to the main control panel 21 but also to the balustrade lighting control panel 22,
Control is performed to turn on and off the balustrade lighting when the man conveyor starts, and to turn off the balustrade lighting when the man conveyor stops, in synchronization with the start and stop of the man conveyor.

FIG. 3 is a diagram showing a conventional control system for a man conveyor, and FIG. 4 is a diagram showing a control system for a man conveyor according to the present invention. In FIG. 3, the control system of the conventional conveyor system includes an upper passenger detector, a lower passenger detector, an upper passenger guide light, a lower passenger guide light, an upper automatic switching SW, and a lower automatic switching S.
W, upper start / stop SW, lower start / stop SW, upper alarm / parallel lighting SW, lower alarm / parallel lighting SW, upper operation guide device, lower operation guide device, upper foot light, lower foot light, main motor drive device , Maintenance SW, refueling device, and balustrade lighting power supply device are connected to the control panel, respectively. Although the description of each device is omitted,
Many devices are centrally connected to one control panel.
As described above, since the control of each device of the man conveyor is centrally controlled by one control panel, there are many wirings and the control panel is large.

Referring to FIG. 4, the control system of the conveyor according to the present invention comprises an upper passenger detector, an upper passenger guide light, and an upper automatic switch SW connected to an upper passenger detection board 25, a lower passenger detector, a lower passenger guide light. , Lower automatic switch SW is lower passenger detection board 2
6, the upper start / stop SW, the upper alarm / parallel lighting SW, the upper operation guide device, and the upper footlight are connected to the upper operation panel 23, the lower start / stop SW, the lower alarm / parallel lighting SW, the lower operation. The guide device and the lower foot light are connected to the lower operation panel 24, the balustrade power supply device is connected to the balustrade illumination control panel 22, and the main motor drive device, the maintenance switch, and the oil supply device are connected to the main control panel.

As described above, the control of each device of the man conveyor is performed by the upper operation panel 23 and the lower passenger detection panel 26, and only the signal for starting and stopping the man conveyor is transmitted via the multiplex communication line 30 to the main control line. It is transmitted to the board. Therefore, the number of wirings is small, and the size of the control panel is smaller than that of the conventional control panel.

When extending the functions of a man conveyor (excluding the expansion of the main motor drive system), add a control panel for the function in the device of the function and connect it to other equipment by multiplex communication. Therefore, the function can be expanded without increasing the size of the main control panel without changing it.

The upper operation panel 23 and the lower passenger detection panel 26 for controlling each device are installed in an empty space for design or in securing strength, such as under a balustrade or inside a passenger detection device pole.

[0017]

According to the present invention, it is possible to reduce the number of wires between each device of the conveyor and the control panel, and to extend the functions without increasing the size of the control panel.
