[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects a large number of remote elevators and an elevator monitoring center with a telephone line, and when an abnormality occurs in any of the elevators, the elevator is notified of the abnormality occurrence. The present invention relates to an elevator emergency contact device that can be automatically notified and mutual contact can be made.

[0002]

2. Description of the Related Art Conventionally, in general, remote elevators scattered in various places are connected to an elevator monitoring center by a telephone line. Automatically dials the telephone number, reports abnormal information to the elevator monitoring center when the line is established, and enables communication between the telephone installed in the elevator car and the telephone at the elevator monitoring center side. Therefore, when a person is trapped in the elevator car, the telephone can be contacted.

[0003]

However, in such a conventional elevator emergency contact device, since the person in the elevator car and the supervisor of the elevator monitoring center communicate with each other through the telephone, the ear It is difficult to contact people with disabilities or those who have difficulty in talking in the elevator car, and it is difficult to contact the elevator, and a long-time confinement occurs due to a delay in responding to the elevator confinement accident. There was a problem that there was a fear and gave passengers in the car a great deal of anxiety.

The present invention has been made in view of the above-mentioned conventional problems, and in the case where an accident occurs in which a deaf person or a person having a conversation is confined, the inside of the elevator car and the elevator monitoring center are also inspected. It is an object of the present invention to provide an elevator emergency contact device capable of smoothly communicating with each other, preventing a confinement accident from being prolonged, and reducing anxiety felt by passengers.

[0005]

An emergency contact device for an elevator according to the invention of claim 1 is provided with an abnormality detecting section for detecting an abnormality of the elevator, and is installed on the elevator side, and is remote when the abnormality detecting section detects an abnormality. While automatically dialing the telephone number of the elevator monitoring center to report an elevator abnormality, a communication terminal that enables two-way communication between the elevator and the elevator monitoring center, and an information input device installed in the elevator car and An information display device, a transmission control unit installed on the elevator side, transmitting information input from the information input device through the communication terminal, receiving information transmitted through the communication terminal, and displaying the information on the information display device; Information display device installed on the monitoring center side to display information input from the elevator side and the elevator side It is obtained by an information input device for inputting information to be displayed on the information display device.

According to a second aspect of the present invention, in the emergency contact device for an elevator according to the first aspect of the present invention, an in-car operation button which is normally used as a call button is used as an information input device in the elevator car. is there.

According to a third aspect of the present invention, in the elevator emergency contact device according to the first aspect of the invention, a touch panel is attached to the information display device as an information input device in the elevator car.

[0008]

In the emergency contact device for an elevator according to the first aspect of the present invention, when an abnormality occurs in the elevator and the abnormality detection unit detects the abnormality, the communication terminal automatically dials the elevator monitoring center to notify the elevator abnormality, and the bidirectional Enable communication.

The function can be switched to the operation button for emergency contact.

Next, from the monitoring center 2, "How many passengers are there in the car? Please press the number buttons."
If an inquiry message such as "If you are injured? Press the door open button, if not, press the door close button" is displayed, the passengers trapped in the car 6 are Operation button 1
Use 4 to reply. For example, if the answer is "Yes", press the door open button, if "No", press the door close button, and if you want to answer the number of people, press the corresponding number button on the floor button. Reply operation.

The information input by the operation button 14 is transmitted to the emergency contact terminal 5, converted into a digital signal by the character code conversion circuit 13, converted into a frequency modulation signal by the data conversion circuit 12, NCU 11, telephone line network 3 Through the elevator monitoring center 2 side.

When the elevator monitoring center 2 receives the data from the emergency contact terminal 5, the data conversion circuit 20
The frequency-modulated signal is converted into a digital signal by the, and further converted into ASCII code data by the character code conversion circuit 19, which is applied to the display device 17 to display the response contents of the passenger.

The monitoring staff looks at the contents of the response, and if further inquiries or instructions are required, he or she inputs them from the information input device 18 and transmits them to the emergency contact terminal 5.

As described above, in the elevator emergency contact device of this embodiment, when the elevator fails and an accident such as car cage confinement occurs, an inquiry message, an operation instruction message, and a relief message from the elevator monitoring center 2 are obtained. Send a message to let the basket 6
It is displayed on the display device 7 in the interior of the car 6, and the passengers in the car 6 can make a reply operation using the operation button 14. Therefore, the confined passengers are deaf or have difficulty in conversation. Even in the case of a poor person, bidirectional communication can be performed between the monitoring center 2 and the elevator car 6, and the passengers who are trapped can feel a sense of security.

In the above embodiment, the operation button 14 installed in the car 6 is switched to the operation button for inputting information in an emergency.
As a common embodiment of the invention of FIG.
It is also possible to make the touch panel larger and to attach a touch panel as an information input device on the front surface so that the user can respond by touching the touch panel according to the content displayed on the display device 7. In this case, the elevator monitoring center 2
On the side, some kinds of information display pattern data required when a failure occurs are registered in advance, and the necessary information pattern data is designated by the input device to instruct transmission.
