Abstract

PURPOSE:To easily execute the supervisory control of a controller to be supervised from a remote location by adding a supervisory control function to a telephone system connected to a public line. CONSTITUTION:In inputting a supervisory command from a command input section 5 at the station A, a data control section 6 analyzes the supervisory command to generate a supervisory request and sends the result to a station B. The station B uses its data control section 6 to analyzes the supervisory request, a supervisory control request transmission section 9 converts the request signal into a signal in matching with the equipment to be supervised and sends the result. The equipment to be supervised in the station B sends the present state of the equipment as a supervisory answer, which is received by a supervisory control answer reception section 10 and analyzed by the data control section 6, converted into a data form suitable for the transmission and sent toward the station A via a public line, analyzed by the data control section 6 and displayed on a data display section 11. In applying the control, the required control signal is sent to the other station by the same procedure.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is used to monitor or control the operation of various devices ranging from devices in power plants and substations to general household electrical devices. (devices to be monitored or controlled are referred to as supervised and controlled devices), regarding telephone equipment connected to public telephone lines, in particular, signals for monitoring or controlling the operating status of the monitored and controlled equipment installed together with this telephone equipment are transmitted to the public. The present invention relates to a telephone device that transmits data via a line to remotely monitor or control the operation of a monitored and controlled device.

(Conventional Technique*) Conventionally, in order to remotely monitor and control devices that require monitoring or control, a dedicated master control device has been required.

(Problems to be Solved by the Invention) The conventional remote monitoring and control device described above is designed exclusively for each monitored and controlled device, and its installation location is also specified. Furthermore, there is a drawback that monitoring or control cannot be performed between these distant parent control devices unless they are connected to each other by a dedicated control line.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a telephone device with a supervisory control function, which generates a signal to monitor or control the operation of a monitored control device, and In a telephone device with a supervisory control function that sends a signal to the monitored control device to monitor or control its operation: a handset that communicates with a telephone device with a supervisory control function of another station via a public line; another station a number input section for inputting a telephone number necessary to call the device with the control function on the holy night; a command input section for inputting a supervisory control command that is a command to monitor or control the operation of the monitored control device of another station; a data display unit that displays the operating state of the monitored and controlled device; a data transmission unit that transmits a supervisory control request and a parent control answer to the telephone device with supervisory control function of another station; a data receiving unit that receives a parent control answer and a supervisory control request transmitted from a telephone device with a supervisory control function; a supervisory control request transmitting unit that transmits a supervisory control request to the monitored control device of the own station; a supervisory control answer receiving unit that receives a parent control answer transmitted from the monitored control device; analyzes the supervisory control command, the supervisory control request, and the supervisory control answer to receive the master control answer of the own station and other stations; A data control unit that generates a signal for monitoring or controlling a monitored control device.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block circuit diagram showing an embodiment of a telephone device with supervisory control function according to the present invention. In FIG. 1, 4 is a number input section for inputting a telephone number, 5 is a command input section for inputting monitoring and control commands, and 6 is for analyzing commands, requests and answers related to monitoring or control, and also outputting signals based on this analysis. 7 is a data transmitting unit that transmits the request and answer to the public line; 8 is a data receiving unit that receives the request and answer from the public line; 9 is a private 10 is a parent control request transmitting unit that sends a request for parent control to the monitored controlled device of the station; 10 is a parent control answer receiving unit that receives a supervisory control answer from the monitored controlled device of its own station; and 11 is a monitoring unit. A data display section 12 displays a control answer, and 12 is a handset for communicating with other telephone devices via a public telephone line.

FIG. 2 shows that the telephone device f1 with a supervisory control function according to the present invention is
Monitors or controls the monitored and controlled device 3 of the own station, and also monitors and controls multiple telephone devices 1 and public lines 2 with monitoring and control functions of other stations.
An example of a system for monitoring or controlling a monitored control device 3 of another station via a public line 2 and a telephone device 1 with a supervisory control function is shown.

Hereinafter, the operation of the telephony device with supervisory control function of the present invention will be explained.

First, in Fig. 1, the telephone number input from the number input section 4 connects the telephone equipment of the local station (referred to as A station) and the telephone equipment of the other station (referred to as B station) connected to the monitored device to a public line. Connected with Thereafter, when a monitoring command is input from the command input unit 5 at station A, the data control unit 6 analyzes the eavesdropping command and generates a monitoring request. The data transmitter 7 transmits this monitoring request to the B station. This monitoring request is received by the data receiving section 8 of the B-side telephone device with monitoring and control function. At station B, the data control unit 6 analyzes the monitoring request and sends the monitoring control request transmitting unit 9
Notify the server of the receipt of the monitoring request. The supervisory control request transmitter 9 of station B converts the request signal into a signal suitable for the monitored device and transmits the signal. B who received the request
The monitored device of the station sends the current state of the device as a monitoring answer to the telephone device with a monitoring and control function to which this monitored device is connected, and this monitoring answer is sent to the monitoring and control answer receiving unit 1.
0, analyzed by the data control section 6, converted into a data format suitable for transmission, and transmitted from the data transmission section 7 to the A station via the public line. This monitoring answer is for station A's telephone equipment with monitoring and control functions! After the data is received by the data receiving section 8 and analyzed by the data control section 6, the data is displayed at the data display section 11.
is displayed.

Now that you have finished the monitoring operation, if you want to perform some kind of control on the monitored control device of another station, send the necessary control signals to the other station's monitoring control using the same procedure as when sending the monitoring signal described above. Send to a feature telephone device.

(Effects of the Invention) As explained above, the present invention makes it possible to easily monitor and control a monitored control device from a remote location by adding a monitoring control function to a telephone device connected to a public line. The present invention has such effects.
