Description

  The present invention relates to an escalator device installed so as to move by moving a plurality of escalators.

  In an escalator device installed to move by moving multiple escalators, if one escalator stops due to a failure or abnormality, etc., the escalator that failed and the subsequent escalator connected to the entrance side of this escalator There was a problem that passengers stayed at the landing between. For this reason, conventionally, when a failure or the like occurs in a certain escalator, all of the subsequent escalators are stopped to stop passenger transportation and prevent the passenger from staying.

  In addition, as a prior art of the escalator device having the above configuration, when one escalator is stopped due to a failure or the like, the failure escalator is suddenly stopped and one subsequent escalator closest to the failure escalator is gently stopped. There has been proposed a system in which the operation of the escalator is continued (see, for example, Patent Document 1).

JP 2007-8657 A

In the device described in Patent Document 1, when one escalator is stopped due to a failure or the like, one subsequent escalator closest to the failed escalator is also stopped.
Further, since normal operation is continued for the escalator other than the broken escalator and the one subsequent escalator closest to the broken escalator, there is a possibility that passengers may stay on the entrance side of the stopped subsequent escalator.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to generate an abnormality in one escalator in an escalator device installed so as to move by moving a plurality of escalators. Even in such a case, it is an object to provide an escalator device capable of continuing the operation of an escalator other than an escalator in which an abnormality has occurred, preventing a decrease in convenience, and preventing a passenger from staying.

  The escalator device according to the present invention is an escalator device that is installed so as to transfer a plurality of escalators to a predetermined destination and is capable of transmitting and receiving signals between the escalators. When an abnormality of the own machine escalator is detected by the abnormality detection means, when the abnormality of the own machine escalator is detected by the transmission means for transmitting an abnormality signal to the other machine escalator and the abnormality detection means, When the escalator is suddenly stopped and an abnormal signal is received from another unit escalator, when the own unit escalator falls under the escalator of the other unit escalator that sent the abnormal signal, the own unit escalator is slowly decelerated, And a control means for continuing the operation at a lower speed than the normal operation. It is.

  According to the present invention, in an escalator device installed so as to move by moving a plurality of escalators, even when an abnormality or the like occurs in one escalator, the operation of the escalator other than the escalator in which the abnormality has occurred is continued. Therefore, it is possible to prevent a decrease in convenience and to prevent passengers from staying.

  In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

FIG. 4 is a plan view showing the descending port of the escalator device according to Embodiment 1 of the present invention.

  The present invention relates to an escalator device installed so as to transfer a plurality of escalators when a passenger moves to a predetermined destination. That is, the example shown in FIG.1 and FIG.2 has shown the case where a passenger transfers three escalators A, B, and C in the case of a movement. Of the three units arranged continuously, A is the central escalator, B is the escalator that continues from the upper entrance to the upper floor of the escalator A, and C is further down from the lower entrance of the escalator A to the lower floor. Shows escalator.

  1 and 2, 1a is a control device for escalator A, 1b is a control device for escalator B, and 1c is a control device for escalator C. The escalators A to C are configured so that signals can be transmitted and received between the control devices 1a to 1c. Since each escalator A, B, C has the same basic configuration, the escalator A is indicated by a, the escalators B, C are indicated by b, c, and the specific configuration of each escalator The description will be given only for the escalator A (the control device 1a). That is, in the escalators A to C, configurations with the same numerals mean that they have the same functions.

The control device 1a includes a passenger sensor 2a, a safety switch (safety SW) 3a, a driver 4a, a receiver 5a, and a CPU 6a.
The passenger sensor 2a constitutes passenger stay detection means for detecting and notifying the stay of passengers on the escalator A, and is installed, for example, on the skirt guard 7 at the exit of the escalator A as shown in FIGS. The Specifically, the passenger sensor 2a is constituted by a photoelectric sensor or the like, and detects the stay of the passenger by continuously detecting the passenger. And the passenger sensor 2a transmits a stay signal with respect to CPU6a by detecting a passenger's stay.

  The safety switch 3a constitutes an abnormality detection means for detecting and notifying an abnormality that has occurred in the escalator A. Specifically, the safety switch 3a is configured to detect various abnormalities of the escalator A such as a step abnormality, a skirt portion or a comb portion abnormality, a handrail speed or a handrail deviation amount abnormality. The safety switch 3a operates when any abnormality occurs in the escalator A, and transmits an abnormality signal to the CPU 6a.

  In addition, the driver 4a sends from its own machine escalator A (hereinafter referred to simply as "own machine") to other machine escalators B and C (hereinafter referred to as "other machine escalator"). The receiver 5a has a function for receiving information (signals) transmitted from other units by the own unit. That is, a signal transmitted from another machine is taken into the control device 1a by the receiver 5a.

The CPU 6a has a function of performing various necessary controls based on input signals and the like. That is, the transmission unit and the control unit are configured by the function of the CPU 6a.
Specifically, the CPU 6a operates the driver 4a when an abnormal signal is input from the passenger sensor 2a, and outputs an abnormal signal and a signal indicating the operating state (driving direction, driving, stopping, etc.) of the own machine. , To the receivers 5b and 5c of other machines. In addition, the CPU 6a performs appropriate control when an abnormality occurs based on an abnormality signal input from the passenger sensor 2a of the own machine or an abnormality signal transmitted from another machine. Specific control will be described later.

  In FIG. 1, 8a to 8c are announcement devices for providing voice guidance to passengers of each escalator. In FIGS. 3 and 4, 9 is a step on which the passenger rides when moving, and 10 is arranged on both sides of the step 9. The moved handrail is shown.

  Hereinafter, based on FIG.5 and FIG.6, the specific operation | movement of the escalator apparatus which has the said structure is demonstrated. 5 and 6 are flowcharts showing the operation of the escalator apparatus according to Embodiment 1 of the present invention. In the following, a specific description will be given on the assumption that, as an example, escalators A, B, and C are used as upstream escalators and some sort of abnormality occurs in escalator A. 5 are basically the same as the operations described in Patent Document 1 (Japanese Patent Laid-Open No. 2007-8657), the description thereof will be simplified as appropriate.

  If an abnormality occurs in any of the escalators during normal operation of the escalator device, the escalator in which the abnormality is detected causes an error signal and the operating status of the own device from the driver of the own device to the control device (receiver) of the other device. A signal is transmitted (S1). When any abnormality is detected in the escalator A as described above, the signal is transmitted from the driver 4a to the control devices 1b and 1c.

  Moreover, in each escalator, when a signal is received by the receiver of the control device, first, in the CPU, whether or not an abnormality signal indicating that an abnormality has occurred in the other machine is included in the signal received from the other machine. Is confirmed (S2, S3). When the reception of the abnormal signal is confirmed in S3, that is, in the control devices 1b and 1c from which the abnormal signal is transmitted from the control device 1a, the escalator A in which the traveling direction of the own machine is detected in each of the CPUs 6b and 6c. It is determined whether or not the escalator in which an abnormality is detected is the same as the traveling direction (hereinafter referred to as “abnormal machine”) (S4). Further, if the traveling direction is the same in S4, the CPUs 6b and 6c determine whether the own machine corresponds to the subsequent escalator of the abnormal machine and whether the abnormal machine has stopped operating (S5, S6). ).

  The succeeding escalator means an escalator connected to the entrance of the reference number machine. For example, when escalators A to C are arranged in the order shown in FIG. 1 and are used as an up escalator, escalator C is the escalator A's subsequent escalator, and escalators A and C are the escalator B's subsequent escalator. Applicable.

When the escalators A, B, and C are operating as uphill escalators, the escalator B proceeds to No in S5 and continues to be continuously operated thereafter (S7). Furthermore, the escalator B performs lighting display etc. and notifies the driving direction to the surroundings (S8).
For an escalator whose driving direction is not the same as that of the abnormal car, the process proceeds from S4 to S9. If the car is a reversible escalator, the process proceeds to S5. If the car is not a reversible escalator, the process proceeds to S7.

  On the other hand, for the escalator A that detects an abnormal signal of its own machine and has not received an abnormal signal from another machine (Yes in S10), the CPU 6a performs control for suddenly stopping the operation of the own machine. . That is, the step 9 of the escalator A is suddenly decelerated and the operation is stopped as it is (S11). At this time, the escalator A performs a blinking display for a sudden stop for safety (S12).

  In the escalator A, after stopping the operation in S11, it is determined whether or not the abnormality signal of the own machine is cleared in the CPU 6a (S13). If the abnormal state of the escalator A is released, the CPU 6a further determines whether or not there is a startup input (S14). If there is a startup input in S14, the output of the abnormal signal from the driver 4a is stopped. Thus, the interlocking restart of each escalator is enabled (S15). Moreover, if there is no start input in S14, the stop state of the escalator is maintained as it is (S16).

  On the other hand, in the escalator C corresponding to Yes in S5, it is next determined whether or not the abnormal machine (escalator A) has stopped operating (S6). This determination is made by the CPU 6c based on a signal transmitted from the driver 4a to the receiver 5c. And in the escalator C, if the escalator A has already restarted operation, it will progress to S7 and will continue a continuous operation.

  On the other hand, when the escalator A is still stopped in S6, the escalator C determines whether there are a plurality of subsequent escalators of the abnormal unit in the CPU 6c (S17). It is determined whether or not the machine is closest to the abnormal machine (S18). When the escalator C corresponds to both S17 and S18, the CPU 6c manages the operation of the other subsequent escalators as well as the operation of the own machine (S19). In addition, when the escalator C corresponds to No of S18, the escalator C will control the operation of the own machine by the other machine closest to the abnormal machine among the escalators following the abnormal machine.

  When the escalator C corresponds to No in S17 or Yes in S18, the CPU 6c next determines whether or not all subsequent escalators of the abnormal machine have a speed switching function (S20). If the speed can be switched for all of the subsequent escalators, the CPU 6c slowly decelerates all of the subsequent escalators and switches to a low speed operation that is slower than the normal operation to continue the operation of the subsequent escalators. (S21). At this time, in consideration of passenger safety, a speed change due to the occurrence of an abnormality is announced from each announcement device of the subsequent escalator (S22).

  Next, the CPU 6c determines whether or not the passenger is staying in the escalator C by the passenger sensor 2c installed at the exit (S23). If no stagnation of the passenger is detected in S23, the subsequent escalator operation is continued until the occupant stagnation is detected by the passenger sensor 2c or the operation of the abnormal machine is resumed. On the other hand, when a passenger stay is detected in S23, the CPU 6c controls all the subsequent escalators of the abnormal number to make a slow stop. That is, the step 9 operated at a low speed is slowly decelerated and the operation is stopped as it is (S24). In consideration of passenger safety, a stop announcement and lighting display are performed (S25, S26).

  When all the subsequent escalators are stopped in S24, the CPU 6c starts counting by a first residence timer (not shown) (S27). The first stay timer is used for monitoring and determining whether or not the passenger stays continuously. In other words, when the first stay timer expires, the CPU 6c determines again whether or not the stay of the passenger is detected by the passenger sensor 2c (S28). And if the stay of a passenger is canceled, it will return to S2 and repeat the above-mentioned operation.

  On the other hand, when detecting the stay of passengers even after the first stay timer expires in S28, the CPU 6c next determines whether or not all the subsequent escalators of the abnormal unit can be reversibly operated, that is, reverses the traveling direction and performs the discharge operation. It is determined whether or not it is possible to perform (S29). In addition, when it corresponds to No in S29, it returns to S23 and the subsequent escalator of an abnormal number machine is stopped until the stay of the passenger by the passenger sensor 2c is no longer detected.

When the reversible operation is possible for all of the subsequent escalators, the CPU 6c sets a second retention timer (not shown) from the specification information of the subsequent escalators of the abnormal number including the own number (S30). In addition, this 2nd residence timer is for determining the operation time for the said discharge operation. This discharge operation time is calculated by the following equation, for example.
Discharge operation time = (HE (n) / SIN (A)) / (Vm / 60) + S1
here,
HE (n): Total floor height of each escalator following the abnormal unit A: Inclination angle of escalator Vm: Minimum operation speed before stop S1: Additional time considering the connection between each escalator.
For example, one escalator follows the escalator C, the height of the escalator C (HE) = 4 m, the height of the escalator C following the escalator (HE) = 6 m, the inclination angle (A) = 30 degrees, Vm = 20 m / Min, S1 = 20 seconds, the discharge operation time is calculated as 80 seconds.

Then, after the setting of the second stay timer is completed, the CPU 6c performs a passenger discharging operation. That is, the driving direction of the subsequent escalator of the abnormal machine is reversed and slowly accelerated, and the low speed operation is performed until the second retention timer expires. At this time, in consideration of passenger safety, an announcement to start the discharge operation and a lighting display are carried out (S32, S33).
Further, the CPU 6c stops the discharge operation when the second retention timer expires, and slowly stops the subsequent escalator of the abnormal machine. When the subsequent escalator is slowly stopped, an announcement to stop and a lighting display are made in consideration of passenger safety (S35, S36).

  According to Embodiment 1 of the present invention, in an escalator device installed so as to transfer a plurality of escalators, when an abnormality or the like occurs in one escalator, the escalators other than the escalator in which the abnormality has occurred are continuously operated. Therefore, it is possible to prevent a decrease in convenience, and it is possible to prevent a passenger from staying.

  For example, when some abnormality occurs in the escalator A shown in FIG. 1, the escalator C that is the subsequent escalator is slowly decelerated, and the operation is continued at a lower speed than the normal operation. That is, even if an abnormality occurs in the escalator A, the subsequent escalator does not stop, and there is no possibility that the convenience is lowered. In addition, since the escalator C is operated at a low speed after an abnormality occurs in the escalator A, the number of passengers getting off the escalator C can be smaller than that during normal operation, and the escalator C exit and the escalator A entrance It is possible to prevent passengers from staying at the landing in between.

  Furthermore, when the passenger sensor 2c detects that the passenger is staying after the escalator C shifts to low speed operation, the escalator C is slowly stopped. For this reason, the stay of the passenger by continuing low-speed driving | operation can also be prevented. In addition, when passenger retention is detected even after a lapse of a predetermined time after the subsequent escalator has stopped slowly, a discharge operation for discharging the passenger is performed. For this reason, even if it is a case where it is extremely crowded, it becomes possible to reliably prevent passengers from staying.

  As described above, according to the above configuration, even when an abnormality occurs in one escalator, it is possible to perform optimal control according to the degree of stagnation of passengers, such as continuation of operation, stop, and execution of discharge operation. .
