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 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
The status information of the device 3 and the power supply status information of the distribution board 6 transmitted from the remote unit 3 are displayed on the screen of the CRT 8.

[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 kinds of devices 5, and some of them 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.

[0008] The present invention has been made in order to solve such problems, it is an purpose of that, the actual power failure situations (such as the entire power failure or partial power failure) be artificially experience The function can be used to assist in speeding up the response to a power failure, and to investigate the cause when the behavior of the device is abnormal , and to restore power.
An object of the present invention is to provide a supervisory control device that facilitates the operator's handling of the situation.

[0009]

In order to achieve such an object, the present invention shows the operating status of each device during a power failure.
Shows operation data at power failure and operation status at power recovery of each device
Power failure simulation database means that stores operation data during power recovery , screen display database means that stores drawing information that shows the installation status of each device, and power failure conditions such as a total power failure or a partial power failure that is input as pseudo information Based on
And a processing means for reading out the operation data at the time of a power outage and the operation data at the time of power recovery 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 both are related. , the display information from the processing means, the power recovery Mr.
In the event of a power failure, a device that automatically returns to the operating state before the power failure
The display means for displaying on the screen is provided separately from the non-returnable devices .

[0010]

[0011]

According to the present invention, the entire building is stopped as pseudo information.
If you enter a power failure condition such as power or partial power failure, the power failure
A power outage that indicates the operating status of the required equipment during a power outage according to the conditions
Power recovery operation showing the time operation data and the operation status at power recovery
When the data is read and the required drawing information is read, the display information that correlates the two is displayed on the screen separately for devices that automatically return to the operating state before the power failure when the power is restored and those that do not. Is displayed in. That is, on the drawing created from the drawing information read from the screen display database means, the power failure operation data and the power recovery operation data of the device read from the power failure simulation database means are blacked out when power is restored. It is displayed so that the device that automatically returns to the previous operating state and the device that does not automatically return 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.
Is equipped with.

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 that symbol and remains 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 .

[0021]

As is apparent from the above description, according to the present invention, whether the power failure is the whole building or the partial power failure is used as the pseudo information.
If you enter any power outage condition, it will be required according to the power outage condition.
Power failure operation data indicating the operation status of
Power recovery operation data that indicates the operation status at power recovery
At the same time, the required drawing information is read and the two are related.
When the power is restored, the information displayed on the
A device that recovers automatically and a device that does not recover automatically
It will be displayed on the screen and the situation at the time of actual power failure
You can experience a similar experience and quickly respond to power outages
As a way to help, and when the device behaves abnormally
You can use the function as an aid in investigating the cause.
Become so. Also, a device that automatically returns when the power is restored.
And the device that does not automatically recover will not be automatically recovered.
Make sure to perform processing such as giving a return command for equipment
This makes it possible for the operator to handle the power restoration.
It will be easy.
