Abstract

PURPOSE:To double a processing quantity of monitor control by a monitor controller comprising a monitor control section and plural processing sections connecting to the control section. CONSTITUTION:The monitor controller is made up of a monitor control section 1 and plural processing sections 2 connecting thereto and each of the processing sections 2 is provided with a processing section identification section 11 to identify each processing section, a main processing section 13, a signal line control section 12 to control the main processing section, a 2-way write read storage section 14 for monitor control connecting to the main processing section, and a subordinate processing section 15 connecting to the 2-way write read storage section 14. The main processing section 13 stores a monitor and control signal to the 2-way write read storage section 14 and the subordinate processing section 15 utilizes the stored signal to implement the processing. Thus, the main processing section and the subordinate processing section implement double processing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control apparatus, and more particularly to improvement of supervisory control between a supervisory control unit and a plurality of processing units connected thereto.

[0002]

2. Description of the Related Art As shown in the block diagram of FIG. 2, a conventional supervisory control apparatus comprises a supervisory control unit 1 and a plurality of processing units 2 connected to the supervisory control unit 1. It has a processing unit identification unit 11 for identifying the signal, a signal line control unit 12 for controlling the supervisory control signal line 3, and a main processing unit 13 connected thereto. Incidentally, 4 and 5 are signal lines.

[0003]

In such a conventional supervisory control device, the supervisory control unit 1 performs supervisory control with a predetermined number of processing units 2, so that the throughput of supervisory control is limited. Has occurred. Therefore, there is a problem that this request cannot be fulfilled when a larger-scale monitoring control is required. An object of the present invention is to provide a supervisory control device capable of doubling the throughput of supervisory control.

[0004]

According to the present invention, a plurality of processing units include a processing unit identifying unit for identifying each processing unit, a main processing unit, and a signal line for controlling the main processing unit. A control unit, a bidirectional writing / reading storage unit for supervisory control connected to the main processing unit, and a subordinate processing unit connected to the bidirectional writing / reading storage unit are provided.

[0005]

The main processing unit stores the monitoring and control signals in the bidirectional writing / reading storage unit, and the subordinate processing unit performs processing using the stored signals. Double processing is possible.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention. A plurality of processing units 2, here m processing units 2 from No1 to Nom, are connected to the monitoring control unit 1 by a monitoring control signal line 3. Each processing unit 2 includes a processing unit identification unit 11 for identifying each processing unit, a signal line control unit 12 for controlling the supervisory control signal line 3, a main processing unit 13, and bidirectional write / read storage. A section 14 and a subordinate processing section 15 are provided, each of which is connected to a required circuit by signal lines 4, 5, 6, 7.

In this configuration, when the monitoring control unit 1 monitors and controls the main processing unit 13 and the sub-processing unit 15 of the predetermined processing unit 2, the monitoring control unit 1 uses the monitoring control signal line 3 to perform a predetermined process. A designation signal is output to the processing unit identification unit 11 to designate a unit. The processing unit identification unit 11 identifies that the processing unit is a predetermined processing unit, and outputs a control signal to the signal line control unit 12 to control the main processing unit 13 and the dependent processing unit 15.
The signal line controller 12 outputs a control signal to the main processor 13 via the signal line 4. The main processing unit 13 outputs monitoring and control signals to the bidirectional writing / reading storage unit 14 via the signal line 6,
Remember. Further, the main processing unit 13 processes the monitoring signal processed in the main processing unit 13 into the signal format of the monitoring control unit 1, and then outputs the monitoring signal to the signal line control unit 12 via the signal line 5. To do.

Further, the subordinate processing unit 15 writes the control signal of the bidirectional writing / reading storage unit 14 via the signal line 7 in the bidirectional writing / reading.
It is read from the read storage unit 14 and is monitored and controlled. Then, the subordinate processing unit 15 writes the result of the monitoring control to the bidirectional writing / reading storage unit 14 via the signal line 7. On the other hand, the signal line processing unit 12 outputs the monitoring signals of the main processing unit 13 and the subordinate processing unit 15 held in the signal line control unit 12 by the monitoring control signal line 3 to the monitoring control unit 1. When one processing unit under processing fails, the monitoring control unit 1 stops the processing executed by the failed processing unit. At this time, the monitoring control unit 1 controls the start of processing to one standby processing unit so that the other processing unit in standby executes the process as a backup.

[0009]

As described above, according to the present invention, in addition to the processing section identifying section, the signal line control section, and the main processing section provided in the processing section, the bidirectional write / read storage section and the subordinate processing section are provided. ,
Since the signal from the main processing unit is stored in the storage unit and the sub-processing unit also performs the processing, the amount of supervisory control can be doubled as compared with the conventional processing unit.
