Abstract

PURPOSE:To retrieve automatically the function state of a function section by sending a signal representing whether or not the function section is a function section, or a supervisory section or a control section to a central processing section from the function section selected by the central processing section. CONSTITUTION:A function condition being whether the supervision section or the control section is set to the function section 3 of a supervisory controller 1 at first. The a constitution position selection signal 5 is sent from the central processing section 2 of the controller 1 to each function section 3. The function section 3 selected by the signal 5 sends a function presence identification signal 12 representing whether the section is the function section for the supervisory section or the control section and a function discrimination signal 13 whether it becomes the supervisory section or the control section to the central processing section 2. When the signals 12, 13 are set automatically to a setting section in the central processing section 2, the central processing section 2 drives each function section 3 so as to transmit/receive an alarm signal from/to a terminal device 4 or send a control signal.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a monitoring and control system for terminal equipment in an overconfident line equipment system.

BACKGROUND OF THE INVENTION FIG. 2 is a block diagram showing an example of the relationship between a conventional monitoring and control device and a terminal device. In the figure, the supervisory control device 1 includes a central processing section 2 and a functional section 3 that can serve as a monitoring section or a control section.

The terminal device 4 is monitored or controlled by the monitoring and control device 1.

In this conventional supervisory control system, first, the functional conditions for the functional unit 3 are set as whether it is a monitoring unit or an f6 control unit.

Then, in response to this, the central processing unit 2 of the supervisory control device 1
In this way, the central processing unit recognizes the functional status of each functional unit. .

Thereafter, the central processing unit 2 sends a selection signal 5 for the configuration position of the monitoring unit 3 to the monitoring unit 3 when the functional unit 3 becomes the monitoring unit, operates the monitoring unit 3, and receives commands from the terminal device 4. The stored alarm information 8 is imported as alarm information 6. Further, the central processing section 2 sends a selection signal 5 for the configuration position of the control section 3 to the control section 3 when the functional section 3 becomes the control section to operate the control section 3, and then sends a control signal 7. Then, the control section 3 sends a control signal 9 to the terminal device 4.

Problems to be Solved by the Invention In the conventional monitoring and control device described above, a setting section is provided in the central processing section of the device to recognize the functional state of the functional section, whether it is a monitoring section or a control section. Because it was
There is a drawback in that the functional state of the functional unit, whether it is a monitoring unit or a control unit, must be manually set in advance in this setting unit.

Ninth Means for Solving the Problems It is an object of the present invention, in order to solve the above-mentioned conventional problems, to provide a setting section in the central processing section with a function that determines whether each functional section is a monitoring section or a control section. The object of the present invention is to provide a supervisory control system that can eliminate the complicated work of manually setting the state and automatically perform the setting.

In order to achieve the above-mentioned object, the present invention includes a plurality of functional units that can function as a monitoring unit that collects alarm signals from monitored terminal devices or a control unit that sends control signals to controlled terminal devices, and these functional units. In a supervisory control method in a communication line equipment system that monitors or controls a terminal device using a supervisory control device consisting of a central processing unit that controls a central processing unit, the central processing unit first transmits the function to each of the functional units. In response, each functional unit sends a function identification signal to the central processing unit indicating whether it will function as a monitoring unit or a control unit, and a control signal indicating whether it will function as a monitoring unit. A function determination signal is sent to determine whether the monitored terminal device is to be used as a monitor, and both signals are set in a setting section within the central processing section, and then the central processing section receives an alarm signal from the monitored terminal device based on the settings. , and employs a supervisory control method characterized by sending control signals to controlled terminal devices.

Operation Since the present invention employs the above-mentioned configuration, the functional status of each functional unit, whether it is a monitoring unit or a control unit, can be automatically set in the setting unit in the central processing unit. Embodiments of the present invention will now be described with reference to the drawings.

FIG. 2 is a block diagram of an embodiment implementing the method of the present invention. In the figure, the supervisory control device 1 includes a central processing unit 2,
It is composed of a functional section 3 which can serve as a monitoring section or a control section. The terminal device 4 is monitored or controlled by the monitoring and control device 1 .

To explain the operation shown in FIG. 2, first, the functional conditions for whether the functional section 3 is a monitoring section or a control section are set. Next, the central processing unit 2 sends a configuration position selection signal 5 for each functional unit 3 to each functional unit 3.

The function s3 selected by this selection signal 5 is sent to the central processing unit 2 by a function presence/absence identification signal 12 indicating whether it will function as a monitoring unit or a control unit. Automatically set.

Thereafter, the central processing unit 2 drives each functional unit 3 to receive the alarm signal 8 from the terminal device 4 as the alarm signal 6 via the monitoring unit 3.
The control signal 7 issued to the section 3 is transmitted through the control section 3 to the control signal 9.
It is sent to the terminal device 4 as .

Effects of the Invention As explained below, according to the present invention, the central processing section sends a selection signal for each functional section to each functional section, and the functional section selected by this selection signal is sent to the central processing section. On the other hand, it sends a function presence/absence identification signal indicating whether it will become a functional section and a function discrimination signal indicating whether it will become a monitoring section or a control section, and these two signals are sent to the setting section of the central processing section. Since the function is automatically set to , the function of each function part can be automatically searched at the start of operation, and even when a function part changes its function, there is no process in which the contents of the setting part are artificially changed. This has the advantage that the functional status of the functional unit can be automatically searched without the need for .
