Description

The present invention relates to a passenger conveyor monitoring device.

[Conventional technology]

As described in Japanese Utility Model Laid-Open Publication No. Sho 57-177801, for example, a lamp is connected to each of the switch groups constituting a safety device, and one of the switch groups operates to operate a passenger conveyor. When the operation is stopped, which switch is operated is indicated by a lamp. In recent years, there has been a method of notifying a monitoring center for remotely monitoring the operating state of a passenger conveyor by operating any of these switches to take measures.

[Problems to be solved by the invention]

However, in the conventional device, the switch operated by the lighting of a lamp provided in a monitoring room or the like in a building is notified, and the safety switch is operated due to mischief of a user or the like. However, if the safety switch operates due to a mechanical failure, it is necessary to contact a maintenance company to have the selected technician deal with it. You have to make a judgment.

Further, in the method of notifying a monitoring center for remotely monitoring the operating state of the passenger conveyor by operation of any one of the safety switches and coping with the situation, if the user operates the safety switch due to mischief, etc. In spite of the fact that it can be dealt with in a local building, the technician of the maintenance company is dispatched, and it is wasteful to dispatch, and the time until restoration is further delayed.

An object of the present invention has been made in view of the above-described conventional technology, and an object of the present invention is to provide a monitoring device capable of promptly responding to recovery of operation of a passenger conveyor by operation of a safety device.

[Means for solving the problem]

In order to achieve the above object, a detection element for detecting an operation state of a passenger conveyor, at least a signal of the detection element is input, and a stop command is output according to a change in the signal, and the operation of the detection element is controlled. In the monitoring apparatus for a passenger conveyor having a monitoring location for performing notification, the monitoring location is remotely controlled by using a first monitoring location provided in a building where the passenger conveyor is installed and a remote location using a communication line. And a second monitoring point for monitoring the operating state of the passenger conveyor, wherein the operation of the detecting element is a first operation for detecting whether or not the passenger of the passenger conveyor is safe, or a passenger. Identification means for identifying whether the operation is the second operation for detecting a failure in the machine room of the conveyor, and selection means for selecting the first and second notification points by the identification means. Those digits.

[Action]

The monitoring location for monitoring the operation status of the passenger conveyor is divided into two locations: a building where the passenger conveyor is installed, and a remote location that is monitored using a communication line. Identify whether the operation for keeping the operation is due to the failure of the mechanical equipment of the passenger conveyor, and in the case of the above-mentioned operation, notify the monitoring point in the building, and in the case of the operation described below, to the monitoring point in a remote place This eliminates unnecessary dispatch of a technician of a maintenance company due to mischief or the like, and also enables early recovery of operation of the passenger conveyor.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is an overall configuration diagram showing an embodiment of a passenger conveyor monitoring device according to the present invention, and FIG. 2 is a block diagram of an abnormality monitoring device.

The inside of the building 1 is endlessly connected to a plurality of treads 7 that travel between entrances and exits of upper and lower floors, and a driving machine 4 that is housed in a machine room 5 formed above the entrances and exits and travels the treads 7. The safety switch 3b that operates when the chain that transmits this power is cut, the safety switch 3a that operates when the hand is pulled into the handrail entrance, the other various safety switches 3c to 3f, and the input of the safety switch are captured. A passenger conveyor including a monitoring device 6 for notification is provided, and a notification device 9 in the monitoring room 8 and a monitoring center 12 of a maintenance company outside the building 1 are provided so as to be connected by a general telephone line 11. ing.

The monitoring device 6 arranged in the passenger conveyor 2 has an input device 13 for inputting signals from the various safety switches 3a to 3f and a control line 18 output from the control device 15 to notify the monitoring center 12. A control line 19 for notifying the notifying device 9 in the monitoring room 8; a discriminating device 14 for performing an AND operation between the control lines 18 and 19 and the outputs of the safety switches 3a to 3f; It comprises a communication device 16 for notifying the center 12 via the general telephone line 11 and an output device 17 for notifying the notification device 9 via the communication line 1D.

Next, the operation will be described. For example, when the user operates the safety switch 3a due to mischief or the like, it is captured by the input device 13, and the control device 15 notifies the monitoring center 12 or
It is determined whether to notify the notification device 9. In this case, since it can be handled in the building, it is not necessary to notify the monitoring center 12 of the maintenance company, but it is sufficient to notify the notifying device 9 in the building, and the signal output 20 is transmitted to the discriminating device 14 via the control line 19. The result is reported to the notification device 9 via the control device 15 and the output device 17.

Further, when the chain is cut off for some reason in the passenger conveyor 2 and the safety device 3a operates, the input device 13 takes it in and the control device 15 notifies the monitoring center 12 or the notification device 9 to determine. In this case, the restoration of the passenger conveyor can only be performed by a technician of the maintenance company, so it must be reported to the monitoring center 12 of the maintenance company, and a signal output 20 is transmitted to the discrimination device 14 via the control line 18,
The control device 15 and the communication device 16 are activated and the result is reported to the monitoring center 12 via the general telephone line 11. The supervisor in the monitoring center 12 that has received the report informs a specialized engineer of the name of the building 1 analyzed from the report data, the number of the failed passenger conveyor, the location of the failure, etc., and takes immediate action.

〔The invention's effect〕

According to the present invention, the monitoring location for monitoring the operation status of the passenger conveyor is divided into two locations: a building where the passenger conveyor is installed, and a remote location that is monitored using a communication line. Identify whether the operation is to maintain the safety of passengers or the operation due to a failure of the mechanical equipment of the passenger conveyor.In the case of the above-mentioned operation, go to the monitoring point in the building, in the case of Since it is selected to notify the monitoring point, there is an effect that unnecessary attendance of a technician of a maintenance company due to mischief or the like is eliminated and that the passenger conveyor can be quickly restored to operation.
