In order that those skilled in the art will better understand the present invention, the following description of the present invention will be taken with reference to the accompanying drawings and detailed description.
Fig. 1 is a flowchart of a state detection method of a dc control protection system according to an embodiment of the present invention. As shown in fig. 1, a method for detecting a state of a dc control protection system includes:
s10: and setting a physical topology network for each direct current control protection device and the physical connection relation of each direct current control protection device in the direct current control protection system according to a preset data structure.
In practical application, corresponding physical connection relations are set according to the performances of different direct current control protection devices, so that the task purpose of the direct current control protection system is achieved. Specifically, firstly, reading physical connection relations among all direct current control protection devices in the direct current control protection system and all direct current control protection devices, and then setting corresponding physical topology networks for the direct current control protection system according to preset data structures according to the physical connection relations among all different direct current control protection devices and all direct current control protection devices. It is understood that the physical connection relationship, that is, the relationship that the direct current control protection devices are connected by using physical connection lines such as optical fibers, ethernet lines, or cables. In other words, the physical topology network is a topology network that is set according to the physical connection relationship in the direct current control protection system. It should be noted that, the physical topology network is generally an undirected graph.
S20: and setting a logic topology network according to the transmission line of each control protection signal in the direct current control protection system.
It will be appreciated that in a dc control protection system there are a variety of control protection signals, each of which is transmitted along a physical connection. Therefore, in this step, a logic topology network is set according to the transmission lines of the direct current control protection signals in the direct current control protection system, specifically, on the basis of a physical topology network, a corresponding directional line is set for each transmission line of the control protection signals, and the transmission lines corresponding to the control protection signals respectively form the logic topology network. It should be noted that, since the transmission route of the direct current control protection signal is directional, the logic topology network is generally an unauthorized directed graph.
Specifically, in actual operation, the direct current control protection system may be further provided with a hierarchical logic topology network, so as to more clearly obtain the hierarchical correspondence of each direct current control protection device in the direct current control protection system. That is, according to the performance of different dc control protection devices, the corresponding level is set, and when the logic topology network is set, the logic topology network is set according to the corresponding level, which specifically includes a station control layer, a pole control layer, a valve group control layer, a valve control layer, an interface device, and the embodiment is not limited to this.
S30: when the target control protection signal is determined, setting virtual loop information flow in the logic topology network according to the transmission line of the target control protection signal.
Specifically, after determining the target control protection signal, tracing back to the source direction of the target control protection signal by depth-first traversal, breadth-first traversal or other traversal modes according to the transmission line of the target control protection signal in the direct current control protection system until the target control protection signal is at the input signal in the direct current control protection system, and setting virtual loop information flow in the logic topology network according to the tracing line of the target control protection signal. The target control protection signal is a control protection signal determined from among the dc control protection signals. And determining the virtual loop information flow corresponding to the target control protection signal in the logic topology network, so that the direct current control protection equipment and the physical connection relation which have influence on the target control protection signal can be obtained.
S40: and displaying the physical topology network, the logical topology network and the virtual loop information flow through a visualization device.
Specifically, the step is to input the obtained physical topology network, logical topology network and virtual loop information flow to a visualization device for display. The specific type of the visualization device is not limited in this embodiment, and may be, for example, an LED display screen, a touch display, or the like. The method for displaying the physical topology network, the logical topology network and the virtual loop information flow through the visualization device comprises the steps of displaying a plurality of different topology networks on the same visualization device, or displaying different topology networks through a plurality of visualization devices; and on the same visualization device, each topology network can be displayed in a tiled or layered mode; the present embodiment is not limited in this regard.
As a preferred embodiment, after the target control protection signal is determined, the virtual circuit information flow corresponding to the target control protection signal may be displayed in a highlighted form on the logic topology network, that is, the virtual circuit information flow of the target control protection signal is located at a corresponding position in the logic topology network, so that the information of the virtual circuit information flow and the relationship between the virtual circuit information flow and the whole direct current control protection system can be more clearly and directly obtained.
According to the state detection method of the direct current control protection system, a physical topology network which is set for each direct current control protection device and the physical connection relation of each direct current control protection device in the direct current control protection system according to a preset data structure is displayed through a visualization device; the logic topology network is arranged according to the transmission line of each control protection signal in the direct current control protection system, and the virtual loop information flow is arranged in the logic topology network according to the determined target control protection signal. Therefore, operation and maintenance personnel can perform fault detection on the direct current control protection system according to the physical topology network, the logical topology network and the virtual loop information flow displayed by the visualization device, so that the efficiency and the safety of operation and maintenance work are improved, and the reliability of direct current control protection equipment is improved.

the signal value of the target control protection signal, the line information of the target transmission line of the target control protection signal, and the device information of the target direct current control protection device in the target transmission line are displayed in a list form by a visualization device.

On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, the method for determining the target control protection signal includes:
detecting abnormal information in the direct current control protection system, and determining a target control protection signal according to the abnormal information.
In actual operation, the control protection signal determined as the abnormality information may be set as the target control protection signal by detecting whether or not there is an abnormality in each control protection signal in the dc control protection system. The mode of judging whether the control protection signal is abnormal or not may be that the control protection signal is compared with a corresponding threshold range, and if the control protection signal exceeds the corresponding threshold range, the corresponding control protection signal is set as a target control protection signal; or, it may be to detect whether the change condition of the control protection signal in a period of time meets the corresponding preset condition, and if the change condition does not meet the corresponding preset condition, set the corresponding control protection signal as the target control protection signal.
In other embodiments, the method for determining the target control protection signal may further include:
and responding to the operation instruction of the user, and determining a target control protection signal according to the operation instruction.
In consideration of the fact that in actual operation, there is a need to detect the transmission condition of the control protection signal, and the detected target control protection signal is the control protection signal selected by the operation and maintenance personnel. Specifically, after a user (operation and maintenance personnel) inputs an operation instruction through a man-machine interaction interface, a control protection signal corresponding to the operation instruction is set as a target control protection signal by responding to the operation instruction of the user.

the physical topology network and/or the logical topology network and/or the virtual loop information flow are stored.
