Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatus.

[0024] Figure 1 This is a flow chart of a method for determining the type of power distribution terminal fault provided by an embodiment of the present invention. This embodiment is applicable to situations where the fault category of a power distribution terminal is determined. The method can be executed by a device for determining the type of power distribution terminal fault. The device for determining the type of power distribution terminal fault can be implemented in the form of hardware and / or software. The device for determining the type of power distribution terminal fault can be configured in an electronic device for determining the type of power distribution terminal fault. Figure 1 As shown, the method includes:

[0025] S110: When a fault event of a power distribution terminal is detected, an initial fault category of the power distribution terminal is determined based on network connection information between the power distribution terminal and a power grid operation master station.

[0026] The network connection information includes network connection status, physical connection status and network delay information.

[0027] Exemplarily, the distribution terminal may be a distribution transformer terminal device, the distribution terminal may be a feeder terminal device, or a station terminal device. The distribution terminal may be set according to actual needs. The initial fault category may be a protocol layer fault, the initial fault category may be a wireless module fault, the initial fault category may be a communication parameter error fault or a distribution terminal fault. The initial fault category may be set according to actual needs. The network connection information may be the network connection status, the network connection information may be the physical connection status, the network connection information may also be the network delay information, and the network connection information may be set according to actual needs. This solution may determine whether a fault has occurred in the distribution terminal by determining whether the content of the message received by the power grid operation master station is abnormal. When a fault event of the distribution terminal is detected, this solution may enter the distribution terminal fault diagnosis process and determine the initial fault category of the distribution terminal based on the network connection information between the distribution terminal and the power grid operation master station.

[0028] In this embodiment, optionally, the initial fault category of the distribution terminal is determined based on the network connection information between the distribution terminal and the power grid operation master station, including: if it is determined that there is a network connection between the distribution terminal and the power grid operation master station, then the initial fault category of the distribution terminal is determined to be a protocol layer fault; if it is determined that there is no network connection between the distribution terminal and the power grid operation master station and the physical connection fails, then the initial fault category of the distribution terminal is determined to be a wireless module fault; if it is determined that there is no network connection between the distribution terminal and the power grid operation master station, the physical connection is successful and the network delay exceeds a preset time threshold, then the initial fault category of the distribution terminal is determined to be a communication parameter error fault or a distribution terminal fault.

[0029] For example, communication between the distribution terminal and the grid operation master station needs to follow a specific communication protocol, namely a protocol. A protocol layer failure may be a protocol parameter error or a problem with the functional implementation of the protocol. The preset time threshold may be 1 minute, the preset time threshold may be 5 minutes, and the preset time threshold may be set according to actual needs. If this solution determines that the network connection between the distribution terminal and the grid operation master station is normal, for example, there is a TCP link connection, then the initial fault category of the distribution terminal is determined to be a protocol layer failure. If it is determined that the network connection between the distribution terminal and the grid operation master station is abnormal and the physical connection fails, then the initial fault category of the distribution terminal is determined to be a wireless module failure. If it is determined that the network connection between the distribution terminal and the grid operation master station is abnormal, the physical connection is normal but the network delay exceeds the preset time threshold, then the initial fault category of the distribution terminal is determined to be a communication parameter error failure or a distribution terminal failure.

[0030] Therefore, by determining the initial fault category of the distribution terminal based on the network connection information between the distribution terminal and the power grid operation master station, the fault category of the distribution terminal can be preliminarily determined, and the cause of the fault of the distribution terminal can be determined.

[0031] S120: If it is determined that the initial fault category is a protocol layer fault, determine the target fault category under the protocol layer fault according to the communication status between the power distribution terminal and the power grid operation master station.

[0032] The communication status can be set based on actual needs. For example, the communication status can be the status generated when the power distribution terminal and the power grid operation master station communicate via messages. The target fault category can also be set based on actual needs. For example, the target fault category can be at least one of the following: initialization link failure, signal failure, public address mismatch, protocol byte mismatch, and general call failure. After determining that the initial fault category is a protocol layer fault, this solution can also determine the target fault category for protocol layer faults based on the communication status between the power distribution terminal and the power grid operation master station.

[0033] In a feasible embodiment, optionally, the target fault category under the protocol layer fault is determined based on the communication status between the distribution terminal and the power grid operation master station, including: if the number of times the power grid operation master station sends the initialization link message reaches a first preset number threshold, and it is determined that there is no fault in the link between the power grid operation master station and the distribution terminal, then the target fault category is determined to be an initialization link failure fault.

[0034] The first preset number threshold can be 3 times, or 5 times. The first preset number threshold can be set according to actual needs. The process of communication between the power grid operation master station and the distribution terminal includes: the power grid operation master station sends an initialization link message to the distribution terminal. After receiving a link status message in response from the distribution terminal, the power grid operation master station sends a request to reset the link message to the distribution terminal. After receiving a positive confirmation of the response to the reset link message from the distribution terminal, the power grid operation master station enters the general call process to obtain information such as telesignaling, telemetering, remote control, and remote adjustment from the distribution terminal. If the power grid operation master station does not receive a response from the distribution terminal after sending the initialization link message to the distribution terminal, the power grid operation master station will send an initialization link message to the distribution terminal at regular intervals until it receives a link status message in response from the distribution terminal. If the number of initialization link messages sent by the power grid operation master station reaches the first preset number threshold, and the communication link between the power grid operation master station and the distribution terminal is fault-free, this solution can determine that the target fault category of the distribution terminal is an initialization link failure.

[0035] Thus, if the number of times the grid operation master station sends initialization link messages reaches a first preset threshold, and it is determined that the link between the grid operation master station and the power distribution terminal is fault-free, then the target fault type is determined to be an initialization link failure. This allows the fault type of the power distribution terminal to be determined based on the number of initialization link messages sent, and the cause of the fault in the power distribution terminal to be determined.

[0036] In another feasible embodiment, optionally, the target fault category under the protocol layer fault is determined based on the communication status between the distribution terminal and the power grid operation master station, including: if it is determined that the power grid operation master station receives the link status message replied by the distribution terminal, and the number of times the power grid operation master station sends a link reset request message within a first preset time reaches a second preset number threshold, then the target fault category is determined to be a signal fault.

[0037] Among them, the second preset number threshold can be 3 times, the second preset number threshold can also be 5 times, and the second preset number threshold can be set according to actual needs. The first preset time can be set according to actual needs, for example, the first preset time can be 10 minutes, and the first preset time can also be 15 minutes. If this scheme determines that after the power grid operation master station receives the link status message replied by the distribution terminal, the power grid operation master station will send a request reset link message to the distribution terminal at fixed intervals until it receives the response reset link message replied by the distribution terminal. If the number of times the power grid operation master station sends the request reset link message within the first preset time reaches the second preset number threshold, then this scheme can determine that the target fault category of the distribution terminal is a signal fault.

[0038] Thus, if it is determined that the power distribution terminal has received a link status message in reply from the power distribution terminal, and that the number of times the power distribution terminal has sent a link reset request message within the first preset time period reaches a second preset threshold, then the target fault type is determined to be a signal fault. This allows the power distribution terminal fault type to be determined based on the number of link reset request messages sent, and the cause of the power distribution terminal fault to be determined.

[0039] In another feasible embodiment, optionally, the target fault category under the protocol layer fault is determined based on the communication status between the distribution terminal and the power grid operation master station, including: if it is determined that the power grid operation master station receives a response reset link message replied by the distribution terminal, and the response reset link message is a negative confirmation, then the target fault category is determined to be a public address non-corresponding fault or a protocol byte number non-corresponding fault.

[0040] The message length for communications between the power grid operation master station and the distribution terminal is specified in the communication protocol, for example, a message length of 1 byte or a message length of 2 bytes. If this solution determines that the power grid operation master station has received a response reset link message from the distribution terminal, and the response reset link message is a negative acknowledgment, then this indicates that the length of the request reset link message received by the distribution terminal does not comply with the protocol, or that the public address does not correspond to that in the protocol. The target fault category is determined to be a public address mismatch fault or a protocol byte mismatch fault.

[0041] Therefore, if the grid operation master station receives a response reset link message from the distribution terminal and the response reset link message is a negative confirmation, the target fault type is determined to be a public address mismatch fault or a protocol byte count mismatch fault. This allows the fault type of the distribution terminal to be determined based on the content of the response reset link message, and the cause of the fault can be determined.

[0042] In this embodiment, optionally, the target fault category under the protocol layer fault is determined according to the communication status between the distribution terminal and the power grid operation master station, including: if it is determined that the response reset link message is a positive confirmation, and the response general call message received by the power grid operation master station is a general call command error or a negative confirmation, then the target fault category is determined to be a public address non-corresponding fault or a protocol byte number non-corresponding fault.

[0043] Among them, if this scheme determines that the response reset link message replied by the distribution terminal is a positive confirmation, and after the power grid operation master station sends a request general call message to the distribution terminal, the distribution terminal replies with a response general call message to the power grid operation master station, and the response general call message is a general call command error or a negative confirmation, then the target fault category is determined to be a public address non-corresponding fault or a protocol byte number non-corresponding fault.

[0044] Therefore, if the response to the reset link message is a positive confirmation, and the response to the general call message received by the power grid operation master station is a general call command error or a negative confirmation, the target fault type is determined to be a public address mismatch fault or a protocol byte count mismatch fault. This allows the fault type of the distribution terminal to be determined based on the content of the response to the general call message returned by the distribution terminal, and the cause of the fault can be determined.

[0045] In this embodiment, optionally, the target fault category under the protocol layer fault is determined based on the communication status between the distribution terminal and the power grid operation master station, including: if it is determined that the power grid operation master station has not received the response general call message sent by the distribution terminal, and the number of times the power grid operation master station sends the general call message within the second preset time is greater than the third preset number threshold, then the target fault category is determined to be a general call failure fault.

[0046] Among them, the third preset number threshold can be 3 times, the third preset number threshold can also be 5 times, and the third preset number threshold can be set according to actual needs. The second preset time can be set according to actual needs, for example, the second preset time can be 10 minutes, and the second preset time can also be 15 minutes. The power grid operation master station will send a request general call message to the distribution terminal at fixed intervals until it receives a response general call message from the distribution terminal. If this scheme determines that the power grid operation master station has not received the response general call message sent by the distribution terminal, and the number of times the power grid operation master station sends a general call message within the second preset time is greater than the third preset number threshold, then the target fault category is determined to be a general call failure fault.

[0047] Thus, if it is determined that the grid operation master station has not received a response general call message sent by the distribution terminal, and the number of general call messages sent by the grid operation master station within the second preset time period exceeds a third preset number threshold, then the target fault type is determined to be a general call failure fault. This allows the fault type of the distribution terminal to be determined based on the number of general call messages sent by the grid operation master station, and the cause of the fault in the distribution terminal to be determined.

[0048] The technical solution of the embodiments of the present invention, when a fault event is detected at a distribution terminal, determines the initial fault category of the distribution terminal based on the network connection information between the distribution terminal and the grid operation master station; the network connection information includes network connection status, physical connection status, and network delay information. If the initial fault category is determined to be a protocol layer fault, the target fault category under the protocol layer fault is determined based on the communication status between the distribution terminal and the grid operation master station. By implementing the technical solution provided by the embodiments of the present invention, the cause of the distribution terminal fault can be determined, and the operational quality of the distribution terminal can be scientifically determined.
