[0001]

[Industrial applications]

 The present invention relates to a central supervisory control system for monitoring and controlling various facilities installed in buildings and various plants.

[0002]

[Prior art]

 Modernized factories and facilities such as plants have many equipment such as special high voltage substations, disaster prevention equipment, and air conditioners, and it is designed to operate these equipment in cooperation with each other. It is necessary to achieve operation according to specifications. Therefore, it is desirable that the operating conditions of all the above-mentioned equipment can be monitored at a specific place and can be controlled from this particular place.Usually, these monitoring and control are all equipment and centralized supervisory control. It is performed by a central supervisory control system that sends and receives operating data and control data to and from the device.

As shown in FIG. 2, a conventional central supervisory control system divides each equipment device into uses such as a power equipment group, an air conditioning equipment group, and a disaster prevention equipment group, and monitors each equipment group for each purpose. By connecting to the SCU devices 51a, 51b, and 51c, which are devices, it is possible to monitor and control each equipment group unit. Then, the central supervisory control system connects these SCU devices 51a, 51b, 51c and the SCU device 53 for central management via a communication line having a communication standard such as RS-232C, and all the SCU devices 53 are connected. It is designed so that the operating status and control status of equipment can be grasped.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional central supervisory control system, the SCU devices 51a, 51b, 51c dedicated to each application are connected via the SCU device 53 for central management, and further, the SCU devices 51a, 51b, 51c are also provided. However, there is a problem that it is difficult to share data and exchange data among the SCU devices 51a, 51b, and 51c dedicated to each application because the communication standards are different.

Further, in the conventional central supervisory control system, the supervisory control device having a large processing capacity collectively manages all the equipment devices, so that the above-mentioned SCU devices 51a, 51b, 51c dedicated to each application are dedicated. Some systems do not require data exchange between the two systems, but in this system, all management functions are stopped even if the supervisory control unit has a minor failure, which will have a large impact on the system. .

Therefore, in the present invention, the SCU devices 51a, 51b, and 51c dedicated to each application are managed in a distributed manner, so that it is possible to reduce the influence on the system due to the failure of the supervisory control device, and at the same time, the SCU device can be reduced. It is an object of the present invention to provide a central supervisory control system capable of easily exchanging data between 51a, 51b and 51c.

【Example】

 An embodiment of the present invention will be described below with reference to FIG.

As shown in FIG. 1, the central supervisory control system according to the present embodiment includes an SCU device 1 which is a supervisory control device for central management installed in a specific place, and an SCU device for automatic control. 2, SCU device 3 for power management, SCU device 4 for air conditioning management, and SCU device 5 for disaster prevention management. Input / output devices (TC-MS) 6.7.8 are connected to the SCU devices 3.4.5 for power management, air conditioning management, and disaster prevention management, respectively. These I / O devices 6, 7, and 8 are connected to equipment groups related to electric power, air conditioning, and disaster prevention, respectively, and the SCU devices 3, 4, and 5 are monitoring units that are completed for each equipment group. And control.

The SCU devices 1, 3, 4, and 5 described above include a CRT device 13 that displays the operating status of patterned equipment and a list of management data, and a display screen of the CRT device 13. A keyboard 14 for switching and inputting control data to facility equipment, an FD device 11 and an HD device 12 for recording information data such as control data and operation data, and a printer 15 for printing information data are connected. ing.

Further, the SCU devices 1 to 5 are connected to each other via a transmission line 9 so as to form a bus type LAN (Local Area Network), for example, according to a unified communication standard such as Ethernet. Therefore, information data is exchanged. The above information data consists of operation data indicating the operation status of each equipment, control data for controlling the equipment, ID data for identifying the equipment, etc. The operation data is obtained from each equipment. The ID data is output together with the ID data and transmitted to the SCU unit 1 for central management via the SCU units 3, 4, and 5 and the transmission line 9 so that each facility device can be monitored. On the other hand, the control data is output from the SCU device 1 for central management and the SCU device 2 for automatic control together with the ID data, and is transmitted to the SCU devices 3, 4, and 5 via the transmission line 9 to generate the SCU device. It is designed to be used to control each equipment by the devices 3, 4, and 5.

The operation of the central supervisory control system having the above configuration will be described.

Will monitor and control the equipment. Further, the SCU devices 3, 4, and 5 convert the operation data together with the ID data of each facility device into a signal form that conforms to a communication standard such as Ethernet and output the operation data to the transmission line 9. And the ID data will be taken into the SCU device 1 for central management and the SCU device 2 for automatic control. The central management SCU device 1 records the operation data and the ID data in a recording device such as the FD device 11 or the HD device 12, and causes the CRT device 13 to display the operation status on the screen. On the other hand, the SCU device 2 for automatic control grasps the operating status of a specific equipment based on the operation data and the ID data, and provides the control data for controlling each equipment so that the equipment is in a predetermined operating state. It will be transmitted to the devices 3, 4, and 5.

Further, the operation data and the ID data are taken in by the SCU devices 3, 4, and 5 other than the transmission source because all SCU devices 1 to 5 have a unified communication standard such as Ethernet. It will be. Then, each SCU device 3, 4, 5 uses each part of the operation data existing on the transmission line 9 in a required portion of the data to operate each device group in cooperation.

As described above, the central supervisory control system of the present embodiment is divided into SCU devices 1 and 2 for central management and automatic control, and applications such as electric power equipment groups, air conditioning equipment groups, and disaster prevention equipment groups. And SCU devices 3 and 4 for monitoring and controlling the installed equipment group, each SCU device 1 to 5 being connected to each other via a transmission line 9, and between each SCU device 1 to 5. When monitoring and controlling all equipment by exchanging information data, all SCU units 1 to 5 exchange data according to a common communication standard.

As a result, it is possible to reduce the influence on the system due to the failure of the SCU devices 1 to 5 by managing the SCU devices 1 to 5 in a distributed manner. Further, since the SCU devices 1 to 5 are connected to each other via the transmission line 9 and data is exchanged according to a common communication standard, the data of all the SCU devices 1 to 5 can be exchanged. It is possible to share data and exchange data easily.
