BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a passenger conveyor according to an embodiment of the present invention.

FIG. 1 is an overall configuration diagram showing an embodiment of a passenger conveyor device of the present invention, FIG. 2 is a basic control mode implemented by an operation control device provided in the embodiment shown in FIG.
That is, a flowchart for explaining the normal direction operation control of the step by the driving command signal. FIG. 3 is a flowchart for explaining the embodiment shown in FIG. FIG. 4 is a flowchart illustrating a priority control mode when a command for priority control is received from the external signal determination control device, that is, a specific direction operation control, in the embodiment shown in FIG.

An escalator 1 as one of the passenger conveyors shown in FIG. 1 is installed at a station where a train (not shown) arrives or departs, for example. This escalator 1 is arranged, for example, on one platform 2 on the lower floor platform FH where a train (not shown) arrives, and on the ticket gate floor FK on the upper floor where a ticket gate (not shown) is provided. And the other entrance 3. Steps 4 that are connected endlessly to convey passengers, and railings 5 that are erected on both sides of the steps 4 are provided between the entrances 2 and 3;
A handrail 6 guided and supported by the balustrade 5 and rotated in synchronization with the steps 4 is provided.

Also, in the vicinity of the entrance 2 on the platform floor FH, a first passenger detecting a passenger entering the step 4 from the entrance 2 is detected.
A detection device 7 is provided. Similarly, in the vicinity of the entrance 3 on the ticket gate floor FK, a second detection device 8 that detects a passenger who gets on the step 4 from the entrance 3 is provided.

An operation control device 9 having functions of storage, calculation and determination is provided in the upper machine room. The operation control device 9 selects the step 4 in a predetermined one direction, that is, in the upward direction, or in another direction, that is, in the downward direction, according to the detection of the passenger by the first detection device 7 or the second detection device 8. The normal direction operation control is performed to move the robot in a desired direction.

In the present embodiment, a signal for executing the specific direction operation control for moving the step 4 in a specific direction, that is, either the upward direction or the downward direction, is given priority over the normal direction operation control described above. Priority control means for outputting is provided.

The priority control means includes, for example, a train approach signal 12 provided at a position separated from the escalator 1.
And an external signal judgment control device 30 for judging this signal and sending a signal of priority control to the operation control device 9 of the escalator 1.

Hereinafter, the basic control mode implemented in the present embodiment configured as described above, that is, the operation control device 9
Will be described with reference to the flowchart of FIG.

Now, for example, the escalator 1 is in the ticket gate floor F
It is assumed that the vehicle is being driven down from K to the home floor FH.
In this case, in an unmanned state in which the passenger does not use the escalator 1, that is, in a state in which the second detection device 8 does not detect the passenger getting into the step 4 (S 11), the escalator 1 is instructed by the operation control device 9. Is in a standby state of the descending operation that has stopped (S12). This state is maintained when there is no passenger getting on the escalator 1 (S13).

When a passenger using the escalator 1 is detected by the second detection device 8 (S14), the escalator 1 performs a descending operation according to a command from the operation control device 9 (S1).
5). Here, the operation control device 9 performs an operation of setting the time obtained by adding the margin time α to the time (a) required to move the passenger by the distance between the detection devices 8 to 7 as the “operation time” (S16). . In this case, when a plurality of passengers use one after another, an operation for updating the setting of the “driving time” is performed each time a passenger detection signal from the second detection device 8 is newly sent. . Then, when the escalator 1 has been operated until almost the above-mentioned "operation time" (S17), the escalator 1 is stopped and kept in a standby state (S18).

In the above description, the steps 4 are stopped in the unmanned state. However, in such an unmanned state, the steps 4 are stopped.
May be set to a low speed of about 5 m / min.

Next, the priority control mode implemented in the present embodiment, that is, the specific direction operation control for moving the step 4 in a specific direction in preference to the normal direction operation control (basic control mode) shown in FIG. Will be described based on the flowcharts of FIGS.

For example, it is assumed that the escalator 1 is driving down from the ticket gate floor FK to the platform floor FH as in the above-described basic control mode.

In such a state, when a train (not shown) approaches the platform and a train approach signal is detected by the detection device 12, the approach signal is taken into the external signal judgment control device 30 (R11). . The external signal determination control device 30 matches train data stored in advance as to whether the captured approach signal train is a train stopped at the station or a passing train (for example, an express train or a freight train). Then, the determination (R12) is performed. As a result of the determination, a signal is sent to the operation control device 9 of the escalator 1 in order to perform the specific direction operation control only in the case of the stopped train (R13). On the other hand, in the case of a passing train, since the passenger does not get off at the station, it is not necessary to perform operation control in a specific direction, so that no signal is sent to the operation control device 9 (R14). Escalator 1 for this
Is in a state where the normal direction operation control (basic control mode) is continued (R15).

The operation control device 9 to which the signal is sent from the external signal judgment control device 30 switches to the priority control mode (specific direction operation control) and performs the following control on the escalator 1.

A signal from the external signal judgment control device 30 is sent to the operation control device 9 (T11). At this stage, since there is a possibility that a passenger is getting on the escalator 1, the basic control mode operation shown in FIG. 2 is continued for a certain period of time (T12), and then stopped (T13).

After the escalator 1 is stopped, the ascending operation toward the ticket gate FK is performed for a certain period of time (set at the time when the passenger who gets off the train has completed the use of the escalator 1) (T14). At the time of this ascent operation, passengers are detected by the first detection device 7, and for passengers who have entered just before the end of the predetermined time, the detection is performed based on the detection signal of the first detection device 7. In the same manner as the above-mentioned "driving time", the vehicle is driven to carry the passenger to the entrance 3 of the ticket gate floor FK. Then, when the set time of the uphill operation ends, the escalator 1 stops (T15), and returns to the basic control mode shown in FIG. 2 (T16).

The external signal judgment control device 30 has a display unit 30a for displaying stored train data and judgment control contents, and an input / output unit 30b for inputting / outputting / changing data.
have. As a result, the train data is rewritten in accordance with the change of the train schedule, and when the train schedule is disturbed, for example, an artificial operation by a station staff or a specific direction operation control by an advanced computer having a human judgment level is performed. The contents can be changed.

According to the present embodiment configured as described above,
Automatically move the step 4 upward or downward depending on the flow of the passenger trying to get into the step 4 and the predicted flow of the passenger in the state before being detected by the detection devices 7 and 8. It has excellent passenger transport function.

In addition, since it has a function of judging whether or not the train is a passing train, in the case of a passing train, the basic control mode of moving the steps 4 downward can be maintained. It has become possible to drive efficiently without disturbing the vehicle.

Further, in the case of installation on the stairs or the like of an existing station, it is only necessary to provide an installation space corresponding to one escalator 1 on the stairs, so that the removal of the stairs can be minimized. Yes, it is economical.

In this embodiment, the escalator provided at the station has been described as an example. However, the present invention is not limited to the escalator provided at the station as described above. For example, it may be provided in such a manner as described above. In addition, the present invention can be applied to an electric road having no steps.

[0030]

As described above, according to the present invention, the steps can be efficiently and automatically moved in either a predetermined direction or the other direction according to the flow of passengers. A passenger conveyor can be obtained.
