Abstract

PROBLEM TO BE SOLVED: To display the power interruption time operation data and power restoration time operation data of an equipment which are read out from a power interruption simulation data base means on a drawing prepared by drawing information so that an equipment to be automatically restored to an operation state held before the power interruption at the time of power restoration and an equipment not to be automatically restored can be distinguished. SOLUTION: Data related to the power interruption of various equipments are stored in a power interruption simulation data base 1-3. When a power interruption condition is inputted, a processing part 1-1 reads out the power interruption time operation data and power restoration time operation data of a required equipment from the data base 1-3, reads out required drawing information from a picture display data base 1-4 and sends display information obtained by relating both the read information to a display control part 1-2. The control part 1-2 displays the display information sent from the processing part 1-1 on the screen of a CRT 8 by distinguishing an equipment (a black symbol) to be automatically restored to an operation state held before power interruption at the time of power restoration and an equipment (flashing black symbol) not to be automatically restored.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control device for supervising and controlling equipment in a facility which receives power and operates.

[0002]

2. Description of the Related Art FIG. 4 shows the configuration of a conventional supervisory control system. In the figure, 1'is a center unit (MCU) provided in the central monitoring room, 2 is a sub-center unit (DCU) distributed in the building, and 3 is a remote unit connected to the sub-center unit 2 by a data transmission line 4. A unit, 5 are various devices arranged in the building, 6 is a distribution board, 7 is a communication line connecting the center device 1 ′ and the sub-center device 2, and 8
Is a CRT, 9 is an input device such as a keyboard, and 10 is a printer.

The center device 1 ', the sub-center device 2 and the remote unit 3 are provided in a hierarchical structure. The remote unit 3 (excluding the remote unit 3-1) is the device 5
Is connected to the device 5 and gives an operation command to the device 5 to collect status information of the device 5. The distribution board 6 receives power from a power source (commercial power source, private power generation) and distributes the power to each device 5. A remote unit 3-1 is connected to the distribution board 6. The remote unit 3-1 collects power supply status information (power supply / power failure).

The state information of the equipment 3 and the power supply state information of the distribution board 6 are transmitted from the remote unit 3 to the center unit 1'through the sub center unit 2. The center device 1'is

[0005]

However, in such a conventional supervisory control system, the operator cannot experience in advance how each device 5 behaves when a power failure occurs. In other words, you cannot try a power outage in a building that is in operation, and you can experience it only when a power outage actually occurs. Therefore, there is a problem that the response is delayed in case of an actual power failure.

There are various types of equipment 5 used, and there are those that automatically return to the state before the power failure when the power is restored.
If the operator does not give a start command from the input device 9, some may remain stopped. Therefore, when a power failure actually occurs, it is difficult for the operator to deal with the power recovery.

Further, during maintenance and inspection of the equipment 5, a partial power failure may occur due to disconnection of only a specific power supply line. For example, in FIG. 4, the distribution board 6 to the device 5-1
The power line to is sometimes disconnected. In such a case, since the distribution board 6 itself is supplied with power, the center device 1 ′ cannot recognize the partial power failure. However, since the power is actually cut off, the behavior of the device 5-1 becomes strange when viewed from the side of the center device 1 '. In such a case, it is difficult and difficult to investigate the cause.

The present invention has been made to solve the above problems, and the object of the first invention is to:
You can have a simulated experience of the actual power outage situation (total power outage or partial power outage), its function as an aid in accelerating the response in the event of a power outage and as an aid in investigating the cause when the behavior of the device is abnormal. It is to provide a monitoring control device that can utilize the. In addition to the object of the first invention, it is an object of the second invention to provide a monitoring control device that facilitates the operator's coping with the restoration of power.

[0009]

In order to achieve such an object, a first invention (an invention according to claim 1) is a power failure simulation database means for storing operation data of each device when a power failure occurs. And a database means for screen display that stores drawing information indicating the installation status of each device,
Processing means for reading out the operation data of the required equipment from the power outage simulation database means, reading out the required drawing information from the screen display database means, and outputting the display information in which the two are related in accordance with the power outage situation given as pseudo information. And display means for displaying the display information from the processing means on the screen.

According to the present invention, when a power failure status (total power failure or partial power failure) is given as pseudo information, the operation data (power failure operation data) when the power failure of the required equipment occurs according to the power failure status is given. The necessary drawing information is read at the same time as the reading, and the display information relating the two is displayed on the screen. That is, the power failure operation data of the device read from the power failure simulation database means is displayed on the drawing created from the drawing information read from the screen display database means.

A second invention (an invention according to claim 2) is a power failure simulation database means for storing operation data of each device when a power failure occurs and operation data of each device when power is restored, and a power failure simulation database means of each device. Depending on the screen display database means that stores the drawing information showing the installation status and the power failure situation given as pseudo information, the power failure simulation database means can be used to display the operation data at the time of the power failure of the required equipment and the power recovery. A processing means for reading out necessary drawing information from the screen display database means and outputting the display information in which the two are related, and the display information from this processing means are automatically set to the operating state before the power failure when the power is restored. A display means for displaying on the screen is provided to distinguish between a device that returns and a device that does not automatically return.

According to the present invention, when the power failure status (total power failure or partial power failure) is given as the pseudo information, the operation data (power failure operation data) when the power failure of the required equipment occurs according to the power failure status and The operation data at the time of power recovery (operation data at power recovery) and the required drawing information are read out, and the display information relating them is automatically restored to the operating state before the power failure when the power is restored. It is displayed on the screen by distinguishing between devices and devices that do not automatically recover. That is,
On the drawing created from the drawing information read from the screen display database means, the operation data at power failure and the operation data at power recovery read from the power failure simulation database means are It is displayed so that the devices that automatically return to the operating state and the devices that do not automatically return to the operating state can be seen.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail based on embodiments. FIG. 1 is a diagram showing a main part of a supervisory control device showing an embodiment of the present invention. In the figure,
The same reference numerals as those in FIG. 4 indicate the same or equivalent components. In this embodiment, the center device 1, the CRT 8 and the input device 9 constitute a monitor control device. Center device 1
Is a substitute for the center device 1 ′ shown in FIG. 4, and includes a processing unit 1-1, a display control unit 1-2, a power failure simulation database 1-3, and a screen display database 1-4.
It has.

Power failure simulation database 1-3
As shown in Fig. 2, "device address", "device type", "installation location", "operation data at power failure (operation data at power failure)", "power recovery Data about power failure (power failure simulation data) such as "operation data (operation data at power recovery)" is stored. In this case, the operation data at power failure is the data indicating the operation status at the time of power failure of the device, "OFF" indicates that it will be in the off state at the time of power failure, "Presence of backup" means by the backup power supply at the time of power failure. Indicates that the operation is continued. In addition, the power recovery operation data is data indicating the operation status of the device at power recovery, and "automatic" indicates that when power is restored, it automatically returns to the operating state before the power failure. “Manual” means that when the power is restored, the operating state before the power failure is not automatically returned to, that is, the operating state before the power failure can be returned only by manual operation.

The screen display database 1-4 stores drawing information indicating the installation status (installation location and connection relationship) of various devices in a building and data for displaying an instruction input screen. Next, a characteristic processing operation in the center device 1 will be described together with the function of the processing section 1-1.

If there is a request for displaying a power failure simulation screen (request from the operator) via the input device 9, the processing section 1-1 displays the power failure condition input screen G1 as shown in FIG. Display on top. On this power failure condition input screen G1, the operator selects whether the power failure is the whole building (total power failure) or the partial power failure. In this case, it is assumed that the partial power failure is selected on the power failure condition input screen G1.

Then, instead of the power failure condition input screen G1, a partial power failure range input screen G2 as shown in FIG. 3B is displayed on the screen of the CRT 8. Where, for example,
Enter the range of partial power failure as "East side of 1st floor". Then, the partial power failure range input screen G2 is displayed on the screen of the CRT 8.
Instead of this, a power failure simulation screen G3 as shown in FIG. 3 (c) is displayed.

On this power failure simulation screen G3,
The operating status of each device on the "East side of the first floor" at the time of power failure is displayed so that it is possible to see which devices automatically return to the operating status before the power failure when the power is restored and which do not. In this example, the symbol of the device that is turned off at the time of power failure is displayed in black (the diagonal line in the figure), and when the power is restored, the device that automatically returns to the operating state before the power failure remains black and the symbol is restored. For devices that do not automatically return to the operating state before the power failure (devices that need to be manually restored), the symbol is black and blinks. In addition, in FIG.3 (c), for convenience, only a part of device of "the east side of the first floor" is shown.

CRT8 of power failure simulation screen G3
Is displayed on the screen as follows. That is, when the range of partial power outage is input as "the first floor east side", that is, when the power outage condition is input as pseudo information,
The processing unit 1-1 reads out the operation data at the time of the power failure and the operation data at the time of the power recovery of the required equipment from the power outage simulation database 1-3 and the required drawing information from the screen display database 1-4 according to the power outage situation. Is read out and the display information relating them is sent to the display controller 1-2. The display control unit 1-2 distinguishes the display information from the processing unit 1-1 into a device that automatically returns to the operating state before the power failure when the power is restored and a device that does not automatically return, that is, the symbol is black. It is displayed on the screen of the CRT 8 by distinguishing between the device which is left as it is and the device which is black and blinks.

In the above description, the case where the partial power failure is selected on the power failure condition input screen G1 has been described, but the power failure simulation screen is similarly displayed on the screen of the CRT 8 when the entire building power failure is selected. It goes without saying that you can do it. Further, in this embodiment, in the power failure simulation screen, it is assumed that the devices that are automatically restored to the operating state before the power failure when the power is restored and the devices that are not automatically restored are displayed separately. May be displayed.

[0021]

As is apparent from the above description, according to the present invention, in the first invention, when a power failure status (total power failure or partial power failure) is given as pseudo information, a required device is selected according to the power failure status. The operation data at the time of power failure is read out and the required drawing information is read out, and the display information relating them is displayed on the screen, so that you can experience the situation during an actual power failure in a simulated manner. The function can be used as an aid for accelerating the response to a power failure and as an aid in investigating the cause when the behavior of the device is abnormal.

Further, in the second invention, when a power failure status (total power failure or partial power failure) is given as the pseudo information, the power failure status operation data and the power recovery status operation data of the required equipment are read according to the power failure status. The required drawing information is read out, and the display information that correlates the two is displayed on the screen separately for the devices that automatically return to the operating state before the power failure when the power is restored and those that do not. It is possible to see at a glance which devices automatically recover when power is restored and which do not, and it is possible to reliably perform a process such as giving a restore command to devices that do not automatically restore. Will be easier.
