Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a status display device that displays a plurality of equipment statuses using a computer and a display device connected thereto.

[Technical background of the invention and its problems]

Generally, a display device such as a CRT is used to monitor equipment conditions that change over time.

By the way, when such a display device is used to monitor a wide range of complexly connected equipment, the operator needs to understand the entirety of the target equipment and make necessary decisions.

However, display devices such as CRTs have a limited display screen area, so when displaying a wide range of target equipment on the screen, the target equipment is divided into multiple pieces according to the area of the display screen of the display device. I was trying to display them individually on the screen.

FIG. 3 shows an example in which the distribution equipment of the power system is divided into a plurality of parts and displayed on a CRT screen. In Figure 3, each section indicated by a dotted line is a division of the power distribution equipment of the power system according to the area that can be displayed on a CRT screen. As shown, a customer 24.25 is normally connected to a distribution line 20 from a breaker 11 via a normally closed switch 21.22 to a normally open switch 30 via a new line switch 23. It shows a state in which the power is being supplied to each customer 24 and 25.

However, if an accident occurs near the breaker 11, for example, the normally open switch 30 shown at the compartment entrance is closed and power is supplied from the breaker 12 shown in compartment C. It is difficult to grasp the overall picture of the equipment by displaying individual compartments 2, for example, compartment A or the opening on a CRT screen, so it is difficult to grasp the overall picture of the equipment. unable to make judgments.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to be able to quickly grasp the entire picture of a wide-ranging and complex target facility, as well as to obtain details of the target range of the equipment elements that constitute the target facility. An object of the present invention is to provide a status display device that can reliably grasp the situation.

[Summary of the invention]

In order to achieve such an object, the present invention reads data of a target facility to be displayed from a macro display database storing data necessary for displaying a plurality of target facilities in a macro manner, displays the data in a macro display on a display device, and displays the data in a macro display device. When the details of the target range of the equipment element are specified for the equipment target displayed as a macro in The present invention is characterized in that data corresponding to the target range of the corresponding equipment element is read out from the accumulated micro display database and displayed on a part of the macro display screen of the display device.

[Embodiments of the invention]

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

FIG. 1 shows an example of the configuration of a status display device according to the present invention when applied to one that displays power distribution equipment of an electric power system on a screen. In Figure 1, 1 is a macro display database in which data for aggregated macro display including multiple switches, disconnectors, consumers, etc. is accumulated corresponding to multiple power distribution facilities, and 2 is this macro display database. The target range of equipment elements such as switches, disconnectors, and consumers that make up the power distribution equipment corresponds to the data accumulated in the macro display database 1, that is, the aggregated range including multiple switches, disconnectors, and demand. This is a micro-display database that accumulates detailed data in a consolidated range, including such information. Also 3
is an arithmetic and control device, and this arithmetic and control device @3 displays the status of the transmission device 4, which receives status signals of equipment elements such as breakers, switches, and disconnectors transmitted from the actual power distribution equipment, and the power distribution equipment. A display device such as a CRT5 is connected. This arithmetic and control unit 5 has a means for reading out data of the power distribution equipment to be displayed from the macro display database 1 according to an operator's request and displaying it on the CRT 5, and an object of the equipment element for the power distribution equipment displayed on the CRT 5. If you indicate on the display screen a range that includes multiple switches, a range that is aggregated including disconnectors, demand, etc. using a light pen or tablet, the target range of the corresponding equipment element will be displayed from the micro display database 2. It is equipped with a means for reading out detailed data and displaying it in a micro display on a part of the display screen of the CRT 5, and when a state change signal of an equipment element from the actual power distribution equipment is inputted from the transmission device 4, the macro display database 1 and the micro display are provided. A data updating means for rewriting data contents in the database 2 is provided.

Next, the operation of the status display device configured as described above will be explained with reference to the display screen shown in FIG.

22 In Fig. 2, 11 and 12 are circuit breakers, 13 is a consolidated display of switches, 14 is a consolidated display of consumers and disconnectors, 15 is a macro display of power distribution equipment, and 16 is equipment This is a micro display section that shows the target range of an element in detail.

To display the power distribution equipment on the CRT 5 in macro mode, when the operator issues a command to the arithmetic and control unit 3, the data corresponding to the power distribution equipment corresponding to the arithmetic and control unit 3 is read from the macro display database 1, and this data is displayed on the CRT5. A macro is displayed on the screen in the macro display section 15 as shown in FIG. On such a macro display screen, the operator can display the integrated display a! of the switches on the display screen. 113 with a light ben or the like, the arithmetic and control unit 3 reads detailed data of the aggregation range corresponding to the aggregation display section 13 of the switch from the micro display database 2, and this data is sent to the CR.
By outputting to T5, the details of the switch aggregation display section 13 are displayed on the micro display section 16 at the lower left of FIG.

Therefore, by simultaneously monitoring the macro display section 15 and the micro display section 16, the operator can easily and quickly grasp the entire situation of the target power distribution equipment, and can accurately judge the status of the entire power distribution equipment. can.

In the above embodiment, the case where the power distribution equipment of the power system is displayed on the screen has been described, but the present invention can be similarly applied to the case where the plant equipment and other target equipment are displayed on the screen.

〔Effect of the invention〕

As described above, according to the present invention, the data of the target equipment to be displayed is read out from the macro display database in which data necessary for displaying a plurality of target equipment in macro is stored, and the data is displayed in macro on the display device. When you instruct the device to specify the details of the scope of equipment elements that are macro-displayed on the device, detailed data of the scope of equipment elements that make up the target equipment are displayed in correspondence with the data stored in the macro display database. The data corresponding to the target range of the corresponding equipment element is read out from the accumulated micro display database and displayed on a part of the macro display screen of the display device, so even if the target equipment is wide and complex, the entire picture can be displayed. It is possible to provide a status display device that can be quickly grasped and also can reliably grasp the details of the target range of the equipment elements constituting the target equipment.
