Description

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 and a monitoring device for remotely monitoring the control 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 However, since the cause of the stop cannot be determined, it is not possible to appropriately determine whether the restart is acceptable. Therefore, the maintenance company is informed of the situation and asked for instructions, or requested to dispatch a specialist engineer. Therefore, there is a problem that the passenger conveyor cannot operate during this time. In particular, this downtime is a major problem in large department stores, transportation stations, and the like, and its reduction is becoming an issue.

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 is provided on the passenger conveyor side and the control room side to transmit this monitoring status to the control room. A wireless device is provided, and the control room further includes a communication control device for transmitting monitoring data to a monitoring station (monitoring center) of a 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 confinement of the user due to a failure stop between floors, which is a problem peculiar to the elevator, and to rescue the user as quickly as possible. This is different from the purpose of the passenger conveyor. That is, even if the passenger conveyor stops, there is no purpose of rescue because it will not be trapped like an elevator, but as described above, the fact that it is stopped because it is a highly public transportation is a major problem. Therefore, the point that is aimed at the quick recovery is a big difference from the elevator.

[0005]

In the above-mentioned prior art, a management room for managing the operation status of the passenger conveyor is provided.
Recently, there has been an increase in the number of cases where the equipment is not installed in a building to save labor.In such a case, there is no person directly monitoring the passenger conveyor, so even if a failure or emergency stop occurs, The above-mentioned problems, such as being inoperable for a long time, are becoming more serious.

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.

An object of the present invention is to provide a passenger conveyor monitoring apparatus which can directly manage the operating status of a passenger conveyor at a monitoring center of a maintenance company and can easily construct a system thereof and is excellent in safety. It is in.
