Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor control device, a monitoring device for remotely monitoring the same, and a related device.

[0002]

2. Description of the Related Art Generally, in a building where a passenger conveyor such as an escalator or an electric road is installed, an administrator who manages the operation status of the passenger conveyor is arranged. This manager is usually a person who works in the electrical room that manages the entire building and is not a maintenance engineer's expert engineer who is familiar with passenger conveyors, so if the passenger conveyor stops abnormally However, it is impossible to determine the cause of the stop, and it is not possible to properly determine whether or not the restart can be performed.
Therefore, we respond to the situation by contacting the maintenance company for instructions or requesting the dispatch of a professional engineer.
During this time, there is a problem that the passenger conveyor cannot be operated. Particularly in public institutions such as large department stores and stations, shortening downtime, improving reliability and safety have become major issues.

Therefore, as one means for solving this problem, a remote monitoring device for passenger conveyors is proposed in Japanese Patent Application Laid-Open No. 1-281287. This device is a microcomputer control device that monitors and controls the operating switches and various safety devices provided in the machine room of the passenger conveyor and the passenger conveyor side and the management room side to transmit this monitoring status to the management room. A wireless device is provided, and the management room is further provided with a communication control device for transmitting monitoring data to a monitoring station (monitoring center) of a maintenance company by using a telephone line.
In the event of an abnormal stop, information is sent from the passenger conveyor control device to the management room, and then sent to the monitoring station of the maintenance company.

As an example of a technique similar to this, which is proposed in an elevator, there is JP-A-56-65779.
In this example, the main purpose is to monitor the operating state of the elevator and to promptly perform rescue and restoration when a user is trapped in the elevator in the unlikely event of an earthquake or fire. Another example is JP-A-58-130876. This example is an example in which a maintenance company and an elevator are connected to automatically inspect whether there is a failure in the elevator for recovery after an earthquake or fire. In these examples,
The purpose of the elevator is to prevent the user from being trapped due to a failure stop between floors, which is a problem peculiar to an elevator, and how quickly to rescue the user. It is different from the purpose of the passenger conveyor. In other words, the passenger conveyor is not trapped like an elevator even if it is stopped, so it has no purpose of rescue, but as mentioned above, it is a public transportation system, so it is a big problem that it is stopped. Therefore, the point that is aimed at immediate recovery is a point that is significantly different from the elevator.

[0005]

In the prior art, in recent years, there has been an increasing number of cases where the control room for controlling the operating condition of the passenger conveyor is not provided in the building for labor saving. In such a case, Since no one is directly monitoring the passenger conveyor, even if there is a failure or an emergency stop, the passenger conveyor is inoperable for a long time, but the above-mentioned problems are becoming more serious.

Further, in order to send the monitoring data to the maintenance company through the management room or the like, it is necessary to construct a means for laying a telephone line for transmitting data from the passenger conveyor to the management room and to the maintenance company. First of all, the complexity was the reason why they did not spread.

An object of the present invention is to provide a passenger conveyor monitoring device which directly manages the operating status of the passenger conveyor at a monitoring center of a maintenance company and can easily construct the system, which is excellent in safety and reliability. It is to provide the related device.

[0008]

In order to achieve the above object, a feature of the present invention is that a wireless communication device (for example, a mobile phone and a modem) that can directly and bidirectionally communicate with a monitoring center of a maintenance company for each passenger conveyor. Etc.) and is configured so that the operating status of the passenger conveyor can be directly managed at the monitoring center, and when the control is performed by this remote monitoring, a fence or display device for preventing progress such as limiting access to the passenger conveyor is provided. It is equipped with an inspection device that can be used to remotely check the functions of various safety devices on the passenger conveyor. In addition, bidirectional communication is enabled to enable the control of the passenger conveyor including stoppage of operation from the monitoring center, and the monitoring center is equipped with a monitor TV device and a guide broadcasting device for monitoring users. Is configured to ensure the management of the.

With the above-mentioned structure, the operation center of the passenger conveyor and the function of the safety device can be directly managed and controlled at the monitoring center of the maintenance company, and at the same time, the system can be easily constructed to ensure safety, workability or reliability. It becomes a monitoring device for passenger conveyors with excellent performance.
