Abstract

PROBLEM TO BE SOLVED: To contact a required place in the maintenance work of an elevator by means of telephone with a simple operation by selecting the telephone number of an information exchange destination as a dialling destination, operating a relay means communicating with a switch means and connecting a jack with a telephone line. SOLUTION: The jack of a telephone set 21 is inserted into a jack so as to operate (depress) a contact switch 16. Then, a dialler 15 executes dialling to the information exchange destination stored in storage means 12 and 13. When the line is closed (connected with an opposite party), a line change-over equipment 17 and the relay 18 are operated, the telephone line 3 is connected with the jack and, then a call is executed between the telephone set and the information exchange destination. Thus, the information contact destination is connected with the telephone only by an easy operation like the operation of the contact switch 16 and also usage except a purpose is prevented since the dialling destination is only the telephone number which is desired to be previously stored.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring terminal device of a remote monitoring system.

[0002]

2. Description of the Related Art A conventional device of this type is disclosed in Japanese Patent Laid-Open No.
As disclosed in Japanese Patent No. 53699, a ten-key and a switch are provided on a driver's panel in an elevator car, and after operating the switch, a desired call destination can be selected by inputting a telephone number with the ten-key. It is known to do so.

[0003]

According to the above-mentioned prior art, during maintenance work such as inspection and repair of the elevator, it is possible to make a telephone contact to the sales office to which the user belongs and the contact information. However, since an arbitrary telephone number is entered with the ten-key pad, there is a problem that the telephone can be used freely except where necessary for performing maintenance work at a business office or the like.

An object of the present invention is to provide a monitoring terminal device of a remote monitoring system capable of making a telephone contact by a simple operation where it is necessary to perform an elevator maintenance work.

[0005]

In order to achieve the above object, the present invention is installed in a building and includes a CPU, a storage means, and an R.
Equipped with AM, input / output interface, dialer and line switching means
When abnormalities occur in these building facilities, in the monitoring terminal device of the remote monitoring system that notifies the monitoring center via the telephone line, please provide the telephone number of the contact for exchanging information about building facilities. While storing in advance in the storage means, a jack for connecting a telephone, a telephone number of the information exchange destination as a dialing destination, and a switch means for activating a dialer, which operates in conjunction with the switch means, This is achieved by providing relay means for continuing the jack and the telephone line.

With the above-mentioned structure, the jack of the telephone (only the handset) is inserted into the jack,
Operate (press) the switch means. Then, the dialer dials the information exchange destination stored in the storage means. When the line is closed (connected to the other party), the line switching means and the relay means operate to connect the telephone line and the jack so that the telephone can communicate with the information exchange destination. become.

As described above, the information contact point and the telephone can be connected by a simple operation such as the operation of the switch means, and the dial destination is only the telephone number to be stored in advance. Can be prevented from being used for.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a system diagram of one embodiment, and FIG. 2 is a flowchart when an elevator maintenance person makes a telephone call.

In the figure, reference numeral 1 is a monitoring terminal device, reference numeral 2 is an elevator monitored by the monitoring terminal device 1,
Building equipment such as an escalator or an air conditioner, reference numeral 3 is a telephone line, reference numeral 4 is a monitoring center that manages and supervises the monitoring status information and abnormality occurrence information of two or more monitoring terminal devices 1, and reference numeral 5 is a maintenance staff member. Shows the sales office that is open. The monitoring terminal device 1 includes a CPU (processing device) 11, a ROM (read only memory) 12 and a RAM (read only memory) 12 in which a telephone number of a monitoring center 4, a telephone number of a sales office 5, programs necessary for monitoring, and the like are stored in advance. Random access memory) 13, input / output interface 14, dialer 1
5. The telephone number of the information exchange destination (in this case, the sales office 5) is selected as the dialing destination, and the contact switch 16 for activating the dialer 15 is controlled by the CPU 11, and the telephone line 3 is connected. When the line switch 17 and the contact switch 16 which are selectively connected to the dialer 15 or the telephone side are pressed, they operate in synchronism with this, connect the maintenance personnel modular jack 19 and the telephone line 3, and the contact switch 16 When it is not pushed and is inoperative, it is equipped with a shared telephone jack 20 and a relay 18 for connecting a telephone line. Reference numeral 17A is a switching contact of the line switching device 17, reference numeral 18A is a contact of the relay 18, reference numeral 21 is a telephone carried by a maintenance person (may be only the handset), and reference numeral 22 is a general telephone. .

Next, a case will be described in which a maintenance person calls the sales office 5 in order to obtain information necessary for performing the maintenance work of the building facility 2 or to report that the maintenance work has been completed.

When contacting the sales office 5, the jack of the telephone 21 carried by the maintenance staff is inserted into the modular jack 19 for the maintenance staff, and the contact switch 16 is turned on.
Then, the line switching device 17 operates and the switching contact 15
The dialer 15 is connected to the telephone line 3 by A, the telephone number of the business office 5 is selected as a dial destination, and the dialer 15 dials the number. When the sales office 5 lifts the handset, the line is closed. When it is confirmed by the monitoring terminal device 1 that the line is closed, the line switch 1
7 is in the non-operating state (excitation to non-excitation), relay 1
8 is controlled to an operating state (from non-excitation to excitation), switching contact 17A and relay contact 18A are switched, connected to telephone line 3 and modular jack 19 for maintenance personnel, and inserted into modular jack 19 for maintenance personnel. A call is made through the telephone set 21 and the telephone set of the sales office 5.

The connection of the telephone 21 and the contact switch 1
A series of operations other than the pressing operation of 6 are performed under the control of the CPU 11.

[0014]

As described above, according to the present invention, telephone contact can be made with a simple operation at a place necessary for performing maintenance work of an elevator.
