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 control device, and a related device.

[0002]

2. Description of the Related Art Generally, in a building where a passenger conveyor is installed, such as an escalator or an electric road, an administrator who manages the operation status of the passenger conveyor is arranged. This administrator is usually a person who works in the electrical room etc. which manages the whole building and is not a specialist of the maintenance company who is familiar with the passenger conveyor, so if the passenger conveyor stops abnormally In this situation, the cause of the stop cannot be determined, and it cannot be properly determined whether or not the restart is acceptable.
Therefore, we are responding by contacting the maintenance company for the situation and asking for instructions, or requesting the dispatch of specialized engineers, etc.
During this time, there is a problem that the passenger conveyor cannot operate. In particular, in public institutions such as large department stores and stations, reduction of non-operation time, improvement of reliability and safety have become major issues.

To solve this problem, a remote monitoring system for a passenger conveyor disclosed in Japanese Patent Application Laid-Open No. 1-281287 has been proposed. This device is a microcomputer control device that monitors and controls the operation switches and various safety devices provided in the machine room of the passenger conveyor, and the passenger conveyor side and the control room side for transmitting this monitoring status to the control room. A wireless device is provided, and the management room further includes a communication control device for transmitting monitoring data to a monitoring station (monitoring center) of the maintenance company using a telephone line.
In the event of an abnormal stop or the like, information is sent from the control device of the passenger conveyor to the management room and then to the monitoring station of the maintenance company.

Japanese Patent Laid-Open Publication No. Sho 56-65779 discloses an example of a similar technique proposed for an elevator.
In this example, the main purpose is to monitor the operating state of the elevator and to immediately perform rescue and recovery when a user is trapped in the elevator in the event of an earthquake or fire. Another example is disclosed in JP-A-58-130876. In this example, a maintenance company and an elevator are connected to automatically check for a failure of the elevator in order to recover after an earthquake or fire. In these examples,
The purpose of this method is to prevent passengers from being trapped due to breakdowns between floors, which is a problem specific to elevators, and to rescue them quickly, and is different from the purpose of passenger conveyors. In other words, even if the passenger conveyor stops, there is no purpose of rescue since it will not be trapped like an elevator, but as mentioned above, it is a highly public transportation, and the stoppage is a major problem. Therefore, the point that the purpose is to recover immediately is a big difference from the elevator.

[0005]

In such a case, The above-mentioned problem has been exacerbated if there is no person directly monitoring the passenger conveyor, so that even if a failure or emergency stop occurs, the system will not operate for a long time.

Further, in order to send monitoring data to the maintenance company through the management room or the like, means such as laying a telephone line for transmitting data from the passenger conveyor to the management room and to the maintenance company must be constructed. In addition, the complexity is a cause for the dissemination of these.

[0007] It is an object of the present invention to provide a passenger conveyor monitoring device which can directly manage the operation status of a passenger conveyor at a monitoring center of a maintenance company, and can easily construct the system, and is excellent in safety and reliability. It is to provide the related device.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, a feature of the present invention is to provide a wireless communication device (for example, a portable telephone and a modem) capable of directly and bidirectionally communicating with a monitoring center of a maintenance company for each passenger conveyor. Etc.), the operation status of the passenger conveyor can be directly managed by the monitoring center, and a progress prevention fence and a display device such as restricting access to the passenger conveyor when controlling by the remote monitoring are provided. It is equipped with an inspection device that can remotely check the functions of various safety devices on the passenger conveyor. In addition, the two-way communication allows the monitoring center to control the passenger conveyor, including stopping the operation. The monitoring center is equipped with a monitor television device and a guidance broadcasting device for monitoring users. It is configured to ensure the management of

With the above configuration, the operation status of the passenger conveyor and the function of the safety device can be directly managed and controlled by the monitoring center of the maintenance company, and the system can be easily constructed, so that safety, workability or reliability can be improved.
