Description

  The present invention relates to an escalator remote monitoring system for monitoring and diagnosing an escalator from a remote place using a public wireless communication network, and more particularly to an escalator remote monitoring system effective for a method of installing an antenna of a wireless communication device in the system. is there.

  An escalator remote monitoring system that performs remote monitoring using a public telephone line network uses a wired public line network to send and receive data between the monitoring center that centrally monitors escalator abnormalities and the escalator monitoring device. Is well known. However, when a monitoring device is installed on an existing escalator, a new public communication line must be installed on a wired public line, which increases the construction period and cost.

  For this reason, for example, those using a public wireless network such as a public telephone network PHS network are known, but even in a communication method using a wireless system, an escalator is mainly composed of metal parts, There was a problem that it was blocked and a good communication state could not be secured.

Therefore, a method is known in which an operation panel for starting and stopping operation provided near the floor of the escalator entrance is made of a non-metallic material, and an antenna of a wireless communication device is installed inside the operation panel (see Patent Document 1). ).

  However, the conventional technology has a problem that when the wireless communication device is installed on an existing escalator, the operation panel must be replaced with a non-metallic component.

  An object of the present invention is to easily install and secure a good communication state in an escalator remote monitoring system that performs remote monitoring using a public wireless network.

  An escalator remote monitoring system according to the present invention is characterized in that an antenna of a wireless communication device connected to a public wireless network is installed at a pole of an escalator hall.

  The remote monitoring system for an escalator according to the present invention is characterized in that an antenna of a wireless communication device connected to a public wireless network is installed on a driving direction indicator.

  According to the present invention, it is possible to easily construct a communication means between an escalator monitoring device and a control center that centrally monitors escalator abnormalities using a wireless communication device.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the overall configuration of the present invention. 1 is a planar antenna connected to the PHS terminal 2 for transmitting and receiving radio waves, 3 is a monitoring device for detecting and diagnosing escalator abnormalities, 4 is an escalator, 4a is an escalator control panel for controlling the escalator, and 5 is a PHS. A public base station, 6 is a public network, and 7 is a control center that monitors abnormal operation and operating state of the escalator 4.

  In this embodiment, when a failure occurs in the escalator 4, the monitoring device 3 constantly transmits and receives data to and from the escalator control panel 4 a and monitors the operation of the escalator 4. The PHS public base station 5 and the public network 6 are connected to the control center 7 to report the failure state of the escalator 4, and the engineer notified from the control center 7 is immediately dispatched to the site to deal with the failure.

  FIG. 2 is a diagram showing an example of the case where the planar antenna 1 is attached to a pole 10 in which a passenger detection center for automatic driving provided at an entrance of an escalator is accommodated. In FIG. 2, reference numeral 1 b denotes a coaxial cable that connects the PHS terminal 2 and the planar antenna 1. In this embodiment, although the case where the planar antenna 1 is attached to the lower entrance of the escalator 4 is shown, it may be attached to the upper entrance.

  The planar antenna 1 may be attached to the surface of the pole 10, but a portion made of a nonconductive material such as acrylic may be provided on the pole 10, and the planar antenna 1 may be installed inside the acrylic portion.

  As described above, in the above-described embodiment, the structure of attaching the antenna of the PHS terminal to the pole 10 installed at the escalator entrance allows easy connection to the monitoring device PHS network, If it is installed at a height of, for example, about 1 m from the floor surface, it is possible to prevent damage caused by a collision of a cart or a cleaning tool.

  Next, another embodiment of the present invention will be described with reference to FIG.

  The present embodiment is different from the above-described embodiment in the mounting structure of the planar antenna 1.

  FIG. 3 is a diagram illustrating an example when the planar antenna 1 is attached to the driving direction indicator 20 provided on the lower surface of the escalator 4 installed side by side as an example.

  In FIG. 3, reference numeral 1 b denotes a coaxial cable that connects the PHS terminal 2 and the planar antenna 1.

  In this embodiment, although the case where the planar antenna 1 is attached to the lower driving direction indicator 20 of the escalator 4 is shown, it may be attached to the upper driving direction indicator 20.

  As described above, in the above-described embodiment, the structure of attaching the antenna of the PHS terminal to the driving direction indicator 20 installed on the lower surface of the escalator can be easily connected to the monitoring device PHS network. Furthermore, it goes without saying that damage due to collision of the cart or the cleaning tool can be prevented.

  In the above-described embodiment, building work may occur in some cases. However, in this embodiment, no building work is required, and when installing a monitoring device on an existing escalator, the construction period and cost This is extremely beneficial because it eliminates the need for

It is a block diagram of the remote monitoring system of an escalator. It is a block diagram of the remote monitoring system of the escalator which shows one Embodiment of this invention. It is a block diagram of the remote monitoring system of the escalator which shows one Embodiment of this invention.
