Example 1

Fig. 1 is a flowchart of a fault location method according to an embodiment of the present invention, where the method may be implemented by a fault location device, and the fault location device may be implemented in hardware and/or software, and the fault location device may be configured in an electronic device. As shown in fig. 1, the method includes:

s101, when any receiving end in the process layer optical fiber diagram is detected to report a substation event GOOSE broken link alarm signal facing a general object of a transmitting end, determining a first secondary virtual circuit diagram of the receiving end according to the process layer optical fiber diagram.

The process layer optical fiber diagram and the secondary virtual loop diagram are configured by the intelligent wave recording device and are used for realizing visualization of a substation event GOOSE network facing a general object, and the associated information of each device can be checked through the process layer optical fiber diagram and the secondary virtual loop diagram. It should be noted that the process layer fiber map mainly focuses on the association relationship between all devices of the GOOSE network, and the secondary virtual loop map mainly focuses on the association relationship between a certain device and other devices.

When detecting that the receiving end reports the substation event GOOSE link breakage warning signal of the sending end facing the general object, the receiving end reports the GOOSE link breakage warning signal of the sending end because the link breakage warning information needs to be sent by the receiving end.

In the embodiment of the invention, when detecting that any receiving end in the process layer optical fiber diagram reports the GOOSE broken link alarm signal of the transmitting end, the first secondary virtual circuit diagram of the receiving end needs to be determined according to the process layer optical fiber diagram, and then other devices except the transmitting end in the first secondary virtual circuit diagram, which have an association relationship with the receiving end, are determined.

Illustratively, fig. 2 shows a first secondary virtual circuit diagram of a receiving end, which is connected to a transmitting end and other devices 1 through optical fibers and GOOSE switches 1, respectively, as shown in fig. 2. It should be noted that other devices may be one or more, and only one is shown in fig. 2 for example.

S102, judging whether the receiving end reports GOOSE broken link alarm signals of other devices in the first secondary virtual circuit diagram, if so, determining that optical fibers connecting a switch of the receiving end and the transmitting end to the receiving end are faulty.

In the embodiment of the invention, after determining other devices, except the sending end, in the first secondary virtual circuit diagram, which have association relation with the receiving end, it is necessary to determine whether the receiving end reports a GOOSE broken link alarm signal of the other devices in the first secondary virtual circuit diagram, that is, determine whether the optical fiber circuit of the other devices- & gtgoose switch- & gtreceiving end has a problem. If the receiving end reports the GOOSE link failure warning signal of other devices in the first secondary virtual loop diagram, the problem of the optical fiber loop of other devices, the GOOSE switch and the receiving end is described, and the problem of the optical fiber loop of the sending end, the GOOSE switch and the receiving end is combined, so that the fault of the optical fiber connecting the receiving end and the switch of the sending end to the receiving end can be determined.

For example, as shown in fig. 2, when the receiving end reports the GOOSE link failure warning signal of the other device in the first secondary virtual circuit diagram, that is, the optical fiber circuit of the other device 1→the GOOSE switch 1→the receiving end has a problem, the optical fiber circuit combining the sending end→the GOOSE switch 1→the receiving end also has a problem, and it can be determined that the fault has a high probability of occurring in the optical fiber between the receiving end and the GOOSE switch 1.

According to the technical scheme, when a substation event GOOSE broken-chain alarm signal facing a general object of a sending end is reported by any receiving end in a process layer optical fiber diagram, a first secondary virtual loop diagram of the receiving end is determined according to the process layer optical fiber diagram; judging whether the receiving end reports GOOSE broken link alarm signals of other devices in the first secondary virtual circuit diagram, if so, determining that the optical fiber connecting the switch of the receiving end and the sending end to the receiving end fails. According to the technical scheme provided by the embodiment of the invention, based on the process layer optical fiber diagram and the secondary virtual loop diagram, the fault position is determined through the signals related to the GOOSE broken link alarm signals, so that the accurate positioning of faults in the GOOSE network can be rapidly completed, and the fault positioning efficiency is improved.

Fig. 3 is a flowchart of a fault locating method according to a second embodiment of the present invention, where the fault locating method is optimized based on the foregoing embodiment, and a scheme not described in detail in the embodiment of the present invention is shown in the foregoing embodiment. As shown in fig. 3, the method includes:

and S201, when any receiving end in the process layer optical fiber diagram is detected to report a substation event GOOSE broken link alarm signal facing a general object of the transmitting end, determining a first secondary virtual circuit diagram of the receiving end according to the process layer optical fiber diagram.

S202, judging whether the receiving end reports GOOSE broken link alarm signals of other devices in the first secondary virtual circuit diagram.

In the embodiment of the invention, whether the receiving end reports the GOOSE broken link alarm signal of other devices in the first secondary virtual circuit diagram is judged, namely whether the optical fiber circuit of other devices, the GOOSE exchanger and the receiving end has problems is judged. If yes, step S203 is executed, and if no, step S204 is executed.

And S203, if the receiving end reports GOOSE broken link alarm signals of other devices in the first secondary virtual circuit diagram, determining that the optical fiber connecting the switch of the receiving end and the sending end to the receiving end fails.

S204, if the receiving end does not report GOOSE broken link alarm signals of other devices in the first secondary virtual circuit diagram, determining a second secondary virtual circuit diagram of the sending end according to the process layer optical fiber diagram.

In the embodiment of the invention, if the receiving end does not report the GOOSE link failure warning signal of other devices in the first secondary virtual circuit diagram, the problem is not caused in the optical fiber circuit of other devices, the GOOSE switch and the receiving end. At this time, a second virtual circuit diagram of the transmitting end needs to be determined according to the process layer optical fiber diagram, and further, other devices, except the receiving end, in the second virtual circuit diagram, which have an association relationship with the transmitting end are determined, so as to assist fault location.

For example, fig. 4 shows a second virtual circuit diagram with a number of transmission end connection switches greater than 1, where, as shown in fig. 4, the transmission end is connected to the reception end and other devices 1 through optical fibers and GOOSE switches 1, and is connected to other devices 2 through optical fibers, GOOSE switches 1 and GOOSE switches 2.

For example, fig. 5 shows a second virtual circuit diagram with a number of 1 sending end connected switches, and as shown in fig. 5, the sending end is connected to the receiving end and other devices 1 through optical fibers and GOOSE switches 1, respectively.

S205, judging whether other devices in the second virtual circuit diagram report GOOSE broken link alarm signals of the sending end.

In the embodiment of the invention, whether other devices in the second virtual circuit diagram report the GOOSE broken link alarm signal of the sending end is judged, namely whether the optical fiber circuit of the sending end, the GOOSE exchanger and other devices has problems is judged. If yes, step S207 is executed, and if no, step S206 is executed.

S206, if other devices in the second virtual circuit diagram do not report the GOOSE broken link alarm signal of the sending end, determining that the internal plate of the receiving end has a fault.

In the embodiment of the invention, if other devices in the second virtual circuit diagram do not report the GOOSE link failure warning signal of the sending end, the optical fiber circuit of the sending end, the GOOSE switch and other devices is not problematic, the optical fiber circuit of the sending end, the GOOSE switch and the receiving end is combined to be problematic, and the optical fiber circuit of the other devices, the GOOSE switch and the receiving end is not problematic, so that the plate in the receiving end can be determined that the fault probability is high.

For example, as shown in fig. 4 or fig. 5, if the other devices in the second virtual circuit diagram do not report the GOOSE link failure warning signal of the sending end, it is indicated that the sending end→the GOOSE switch 1→the optical fiber circuit of the other devices 1 are not problematic, the section of the optical fiber circuit combining the sending end→the GOOSE switch 1→the receiving end is problematic, and the other devices 1→the GOOSE switch 1→the optical fiber circuit of the receiving end are not problematic, so that it can be determined that the fault probability is high in the internal plate of the receiving end.

S207, if other devices in the second virtual circuit diagram report the GOOSE broken link alarm signal of the sending end, determining the target number of switches connected with the sending end according to the second virtual circuit diagram.

In the embodiment of the invention, if other devices in the second virtual circuit diagram report the GOOSE link failure warning signal of the sending end, the problem of the optical fiber circuit of the sending end, the GOOSE switch and other devices is described, and at this time, the target number of the switching connected with the sending end needs to be determined according to the second virtual circuit diagram to assist in fault location. If the target number is greater than 1, step S208 is performed, and if the target number is 1, step S211 is performed.

And S208, when the target number is greater than 1, judging whether the switch connecting the receiving end and the sending end is the same as the switch of other devices connecting the sending end and reporting the GOOSE broken link alarm signal in the second virtual circuit diagram.

In the embodiment of the invention, when the target number is greater than 1, it is necessary to determine whether the switch connecting the receiving end and the sending end is the same as the switch of other devices connecting the sending end and the sending end reporting the GOOSE link failure warning signal in the second virtual circuit diagram, so as to assist in fault location. If yes, go to step 209, if not, go to step S210.

S209, if the switch connecting the receiving end and the sending end is the same as the switch of other devices connecting the sending end and the sending end in the second virtual circuit diagram and reporting the GOOSE broken link alarm signal of the sending end, determining that the switch connecting the receiving end and the sending end fails.

In the embodiment of the invention, if the switch connecting the receiving end and the sending end is the same as the switch connecting the sending end and other devices reporting the GOOSE link failure warning signal of the sending end in the second virtual circuit diagram, the switch connecting the sending end, the GOOSE switch, the optical fiber circuit of the receiving end, the sending end, the GOOSE switch, the optical fiber circuits of other devices, the GOOSE switch and the optical fiber circuit of the receiving end are all problematic, and the switch connecting the receiving end and the sending end can be determined to have high failure probability.

For example, as shown in fig. 4, if the switch connecting the receiving end and the sending end is the same as the switch connecting the sending end and other devices that report the GOOSE link failure warning signal of the sending end in the second virtual circuit diagram, that is, the other devices 1 in the diagram report the GOOSE link failure warning signal of the sending end, that is, the sending end→the GOOSE switch 1→the optical fiber circuit of the other devices 1 are problematic, the optical fiber circuit combining the sending end→the GOOSE switch 1→the receiving end is problematic, and the optical fiber circuit of the other devices 1→the GOOSE switch 1→the receiving end is not problematic, it can be determined that the fault probability is high in the GOOSE switch 1.

And S210, if the switch connecting the receiving end and the sending end is different from the switch of other devices connecting the sending end and the second virtual circuit diagram and reporting the GOOSE broken link alarm signal of the sending end, determining that the optical fiber connecting the switch of the receiving end and the sending end to the sending end fails.

In the embodiment of the invention, if the switch connecting the receiving end and the sending end is different from the switch connecting the sending end and other devices reporting the GOOSE broken link alarm signal of the sending end in the second virtual circuit diagram, the optical fiber circuit combining the sending end, the GOOSE switch and the receiving end is problematic, and the optical fiber circuit combining the sending end, the GOOSE switch and other devices is problematic, the other devices, the GOOSE switch and the optical fiber circuit of the receiving end are not problematic, and the probability of occurrence of faults in the optical fiber connecting the receiving end and the switch of the sending end to the sending end can be determined.

For example, as shown in fig. 4, if the switch connecting the receiving end and the sending end is different from the switch connecting the sending end and other devices in the second virtual circuit diagram for reporting the GOOSE link failure warning signal of the sending end, that is, the other devices 2 in the diagram report the GOOSE link failure warning signal of the sending end, that is, the sending end→the GOOSE switch 1→the GOOSE switch 2→the optical fiber circuit of the other devices 2 are problematic, the optical fiber circuit of the combination of the sending end→the GOOSE switch 1→the receiving end is problematic, and the optical fiber circuit of the other devices 2→the GOOSE switch 1→the receiving end is not problematic, so that it can be determined that the failure probability is high between the sending end and the GOOSE switch 1.

S211, when the target number is 1, determining that the switch connecting the receiving end and the sending end fails to the sending end.

In the embodiment of the invention, when the target number is 1, the optical fiber loop of the sending end, the GOOSE switch and the receiving end is combined to generate a problem, the sending end, the GOOSE switch and the optical fiber loop of other devices are combined to generate a problem, and whether the optical fiber connecting the receiving end and the switch of the sending end to the sending end or the switch connecting the receiving end and the sending end to the sending end is in failure cannot be determined, so that the switch connecting the receiving end and the sending end to the sending end is in failure is determined.

For example, as shown in fig. 5, a problem occurs in the optical fiber loop from the transmitting end to the GOOSE switch 1 to the receiving end, a problem occurs in the optical fiber loop from the transmitting end to the GOOSE switch 1 to the other devices 1, at this time, whether the optical fiber between the transmitting end and the GOOSE switch 1 is faulty or the GOOSE switch 1 is faulty cannot be determined, and then the fault from the transmitting end to the GOOSE switch 1 is determined.

S212, determining an interrupted communication line in the process layer optical fiber diagram according to the fault position, and determining remote signaling remote control information of transmission failure according to the interrupted communication line.

The remote signaling and the remote control are information transmission modes commonly used in a remote monitoring and control system and are used for monitoring and controlling the state of equipment or a system.

In the embodiment of the invention, after the fault position is determined, the interrupted communication line in the process layer optical fiber diagram can be determined according to the fault position, and the remote signaling remote control information of failed transmission can be determined according to the interrupted communication line.

S213, generating fault prompt information according to the fault position and the remote signaling remote control information of the transmission failure, and guiding operators to overhaul the faults.

In the embodiment of the invention, after the remote signaling remote control information of the transmission failure is determined, the fault prompt information can be generated according to the fault position and the remote signaling remote control information of the transmission failure, so as to guide operators to overhaul the fault and improve the efficiency of fault repair. Optionally, the operator may be prompted by popping up a prompt box, where the content of the prompt box is that remote signaling remote control information according to the fault location and the transmission failure generates fault prompt information.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.

The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.
