Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide device, and more particularly to an elevator guide device that notifies a message regarding an abnormal state when an abnormal state occurs.

<Prior Art> In recent years, a building's control room and a monitoring center are connected by a communication line to monitor the crime prevention and disaster prevention of the building, the operation of various equipment in the building, and even the installation in the building. Centralized monitoring systems have been widely adopted in which the operating states of existing elevators are monitored by corresponding monitoring devices, and monitoring information is reported to a monitoring center.

In this type of centralized monitoring system, the elevator monitoring device is provided with an abnormal state selection circuit for detecting the state of the elevator, and when the abnormal state of the elevator is detected by the abnormal state selection circuit, the monitoring device transmits it via a communication line. An abnormal condition is reported to the monitoring center.

Further, by pressing a call button provided in the car of the elevator, it is possible to make a call by the communication device between the passenger in the car and the monitoring center.

For this reason, for example, the elevator power supply fails,
If the car remains stopped in the middle of the hoistway, the abnormal condition selection circuit detects an abnormal condition, and the monitoring device transmits a notification signal indicating a failure of the power supply device to the monitoring center. Also, if a passenger suspicious that the car is still stopped in the middle of the hoistway presses the call button in the car, the car and the monitoring center are connected to each other by the communication device, and the passenger is You can receive explanations from the monitoring center about the details of the accident, the recovery schedule, or the rescue schedule.

On the other hand, at the monitoring center that received the notification signal of the abnormal condition from the monitoring device, immediately notified the service company of the occurrence of the accident and its contents, and the service company who received the contact,
A serviceman rushes to the scene. Until the serviceman arrives, the passenger in the car can wait for rescue while talking to the monitoring center by the communication device as described above.

<Problems to be Solved by the Invention> In the above-described centralized monitoring system, a call cannot be made from the monitoring center side to the inside of the car. For this reason, if the passengers in the elevator are only persons with disabilities who cannot press the call button in the car, the elderly, or children, the passengers in the car will not be given any information from the outside, and We have to wait for restoration or rescue.

It would be nice if a serviceman from a service company could arrive at the scene quickly, but if the serviceman is caught in a traffic jam and the arrival may be delayed, these passengers will feel extremely anxious and frustrated in the car. I will have to wait for the recovery or rescue of the accident.

On the other hand, since the information on the accident is not reported even to the user who is trying to use the elevator at the hall, he / she has no idea what time the elevator can be used, which causes discomfort and irritation.

The present invention has been made in view of the current state of the above-described centralized monitoring system of this type, and its purpose is to explain the occurrence of an abnormal state of an elevator and the progress of countermeasures at a monitoring center when the elevator is in an abnormal state. However, it is an object of the present invention to provide an elevator guide device that can be notified to at least passengers in a car and can wait for the recovery or rescue of an accident without causing the passengers to feel uneasy or frustrated.
