Description of the Related Art Conventionally, generally, elevators at a plurality of locations are connected to a monitoring center by a communication line, and each elevator is remotely and centrally monitored. If an abnormality occurs at any of the elevators, the monitoring center detects it. In an elevator remote monitoring system that dispatches a technician for maintenance and inspection, one that uses a dedicated communication line separate from the general telephone for remote monitoring, and the customer's general telephone line There are some that are also used for monitoring.

In the former remote monitoring system for elevators that uses a dedicated line, a new communication line has to be drawn in for remote monitoring, which is a costly problem.

On the other hand, in the latter remote monitoring system for elevators that also uses the communication line of the general telephone, when the customer's customer uses the communication line of the customer (telephone line owner), the general telephone is off-hook. In addition, if the remote monitoring terminal uses the communication line, the telephone user cannot hear the dial tone, which causes an illusion that the telephone may have broken down.

[0005]

As described above, in the conventional remote monitoring system for an elevator which also uses the communication line of the customer's general telephone, remote monitoring information is transmitted and received between the remote monitoring terminal and the monitoring center. In the middle of the process, even if the customer tried to use the ordinary telephone, he could not hear a dial tone and could be mistaken for a failure, and there was a problem that he did not pay much attention to the customer.

In view of such conventional problems, the present invention provides remote monitoring of an elevator if there is an off-hook of a general telephone while transmitting / receiving remote monitoring information of an elevator using the same communication line. Provide a remote monitoring system for elevators that automatically outputs a voice message indicating that it is in use for communication to a standard telephone, eliminates the possibility of telephone users mistaken for a telephone failure, and improves service. The purpose is to

[0007]

According to the present invention, a remote monitoring terminal having an automatic calling function and an automatic receiving function and a general telephone are installed side by side on the same communication line, and the remote monitoring terminal and the elevator monitoring center are connected to the communication line. In a remote monitoring system for an elevator that sends and receives monitoring information by connecting using a remote monitoring terminal, when the terminal is connected using a communication line to a monitoring center and sending and receiving monitoring information, Communication line monitoring means for detecting that the general telephone is off-hook to use the communication line, and when this communication line monitoring means detects the off-hook of the general telephone, the general telephone is used for remote monitoring communication of the elevator. And a voice synthesizing means for outputting a voice message indicating that it is in use.

[0008]

In the remote monitoring system for an elevator according to the present invention, if the customer's general telephone is off-hook while transmitting / receiving the monitoring information using the communication line between the remote monitoring terminal and the monitoring center, communication is performed. The line monitoring means detects the off-hook, and the voice synthesizing means outputs a message notifying that the communication line is in use for sending and receiving the monitoring information of the elevator to the off-hook general telephone. Can inform the user.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of an embodiment of the present invention. In the elevator remote monitoring system of this embodiment, an elevator control panel 1 for controlling the operation of the elevator, and an abnormality of the elevator, A remote monitoring terminal 2 that detects whether or not a failure has occurred, notifies the remote monitoring center, and receives a signal from the remote monitoring center to make a necessary response, and the remote monitoring terminal 2 and a general telephone line. It comprises a monitoring center 4 connected via 3 and a general telephone 5 connected to the general telephone line 3 together with the remote monitoring terminal 2.

The remote monitoring terminal 2 controls the communication with the elevator control panel 1 through the cable 6, the communication with the monitoring center 4 through the telephone line 3, and further controls the operation of each internal circuit. A control unit 7 composed of a computer, a telephone line 3 as described later.
Is used for transmitting and receiving remote monitoring information, a voice synthesizing unit 8 for synthesizing a message for transmitting by voice to a person who has off-hooked the general telephone 5, the remote monitoring terminal 2 and the general telephone 5 are connected to the telephone line 3. A telephone line interface (I / F) 9 to be connected and a telephone line monitoring unit 10 for monitoring whether the telephone line 3 is used by the remote monitoring terminal 2 or the general telephone 5 are provided. In addition, the remote monitoring terminal 2
Is a communication content detection unit 11 that detects the content of communication between the remote monitoring terminal 2 and the monitoring center 4, and this communication content detection unit 11
The voice data storage unit 12 stores voice data of a message prepared for each type of communication content detected by.

Next, the operation of the remote monitoring system for the elevator having the above configuration will be described.

Normally, when the customer's customer off-hooks the telephone 5, the line monitoring unit 10 detects this and transmits it to the control unit 7, and starts transmission / reception of remote monitoring information until this general telephone communication is completed. Prohibit

Next, the telephone line 3 connects the remote monitoring terminal 3 and the monitoring center 4 for inquiries from the remote monitoring center 4 at regular intervals or, conversely, for transmitting monitoring information in an emergency from the remote monitoring terminal 2. Line monitoring unit 10 detects it and transmits it to the control unit 7, and if the customer at the customer takes the telephone 5 off-hook in this state, the line monitoring unit 10 detects it. Is detected and transmitted to the control unit 7.

The control unit 7 receives this signal,
When it is recognized that the telephone is off-hook during the operation of the remote monitoring function, the communication content detection unit 11 detects the type of communication content on the remote monitoring function side. The detection of the communication content is to identify whether it is an inquiry from the monitoring center 4 or, conversely, a transmission from the remote monitoring terminal 2 side due to the occurrence of an emergency.

When it is detected that the communication from the monitoring center 4 is for inquiry, in this case, the communication is completed in a fixed time in the daily routine, so the control unit 7 From the voice data storage unit 12, the line is in use, for example, "The line is currently being used for remote monitoring of the elevator. It will take about 3 minutes, so please call again." The voice data that tells how long it lasts is called and given to the voice synthesizer 8. Upon receiving the voice data from the control unit 7, the voice synthesizing unit 8 performs voice synthesizing, sends the message to the telephone 5 that is off-hook, and makes it heard by the person who is using the telephone 5.

When the communication content detecting unit 11 detects that the remote monitoring terminal 2 is communicating with the monitoring center 4 due to an emergency situation in the elevator, how long the communication time is in this case. Since it is not certain that it will end with, the control unit 7 from the voice data storage unit 12, for example, "I am contacting the monitoring center because of an elevator failure right now. Please wait a while and call again." , Voice data that informs the communication contents and line use is called, and this is synthesized by the voice synthesizer 8
In the same manner as described above, the voice synthesizing unit 8 voice-synthesizes the voice data from the control unit 7, sends the message to the telephone 5 that is off-hook, and informs the person who is trying to use the telephone 5.

As described above, in the elevator remote monitoring system of this embodiment, when the same telephone line is used for both the elevator remote monitoring and the general telephone, the telephone line is used for remote monitoring communication. If there is an off-hook of the telephone while you are on the line,
You can automatically send a guide message to the phone to inform the customer's user that the phone is currently unavailable and how long it will be available, even if the phone is off-hook as before. Since there is no dial tone, it is possible to avoid a situation that might make you think that it has broken down, and you can improve the service.

The present invention is not limited to the above-mentioned embodiment, and the guide message can be arbitrary from simple to complicated as required.
