[0002] With the rapid development of my country's national economy, the demand for electricity from users is also gradually increasing. Based on business needs, it is often necessary to switch the status of disconnectors on transmission lines in substations. For example, to ensure stable power supply to users, it is necessary to ensure that the disconnectors on transmission lines in the substation are fully closed. To ensure the safety of personnel maintaining and repairing transmission lines and transformers, it is necessary to switch the disconnectors on transformers and transmission lines in the substation to a fully open state, thus requiring the identification of the switched disconnector status.

[0003] Currently, the status of disconnectors is usually identified manually. However, this manual method is time-consuming and labor-intensive, and is prone to errors, thus reducing the efficiency and accuracy of disconnector status identification. Summary of the Invention

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

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0034] Example 1

[0035] Figure 1 This is a flowchart of a disconnector status identification method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the status of a disconnector needs to be identified, particularly when the status of a disconnector is identified through a disconnector image. This method can be executed by a disconnector status identification device, which can be implemented in hardware and / or software. This device can be configured in the processor of the disconnector status identification system. Figure 1 As shown, the method includes:

[0036] S110. Collect the current disconnector image corresponding to the status recognition box of the disconnector.

[0037] The disconnect switch may include a closing pointer and an opening pointer. The closing and opening pointers can rotate synchronously. The closing pointer can be one pointer used to indicate the closed state of the disconnect switch. The opening pointer can be another pointer used to indicate the open state of the disconnect switch. A closing indicator is a sign connected to the closing pointer. For example, a closing indicator can be a square sign with the character "Closed" on its surface. An opening indicator is a sign connected to the opening pointer. For example, an opening indicator can be a square sign with the character "Open" on its surface. A status recognition frame can be a square frame used to determine the current image recognition position of the disconnect switch. The current disconnect switch image can refer to the image captured by the imaging device that includes the status recognition frame.

[0038] Specifically, the imaging device can capture images of the status recognition frame to obtain the current image of the disconnect switch. The processor acquires the current disconnect switch image corresponding to the status recognition frame of the disconnect switch.

[0039] It should be noted that when the circuit is closed, the closing indicator connected to the closing pointer is in the status recognition frame, and when the circuit is opened, the opening indicator connected to the opening pointer is in the status recognition frame.

[0040] S120. Based on the current disconnector image, determine the current indicator in the status recognition frame.

[0041] The current sign can refer to the sign image that is in the status recognition frame.

[0042] Specifically, based on the current disconnector image, the position of the status recognition box in the current disconnector image is determined, and the status recognition box at that position is recognized to obtain the current indicator in the status recognition box.

[0043] S130. Identify the current indicator and determine the current status of the disconnector.

[0044] The current disconnector status can refer to the current position of the disconnector. For example, the current disconnector status can be, but is not limited to, closed and open states.

[0045] Specifically, the current status of the disconnector valve can be identified by determining whether the current indicator is a closed or open indicator. For example, the current indicator can be compared with a closed indicator image; if they are completely identical or the current indicator is partially closed, then the current indicator is determined to be closed. Similarly, the current indicator can be compared with an open indicator image; if they are completely identical or the current indicator is partially open, then the current indicator is determined to be open. If the current indicator is identified as closed, the current disconnector valve status is determined to be closed. If the current indicator is identified as open, the current disconnector valve status is determined to be open.

[0046] The technical solution of this invention acquires the current disconnector image corresponding to the status recognition frame of the disconnector. The disconnector includes a closing pointer and an opening pointer. When the disconnector is closed, a closing indicator connected to the closing pointer is in the status recognition frame; when the disconnector is open, a closing indicator connected to the opening pointer is in the status recognition frame. Based on the current disconnector image, the indicator currently in the status recognition frame is determined, thereby automatically determining the current disconnector status. The entire recognition process requires no manual intervention, achieving automatic disconnector status recognition and improving the efficiency and accuracy of disconnector status recognition.

[0047] Example 2

[0048] Figure 2 This is a flowchart of a disconnector status identification method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment describes in detail the process of identifying the current indicator and determining the current disconnector status. Explanations of terms that are the same as or corresponding to those in the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0049] S210. Collect the current disconnector image corresponding to the status recognition box of the disconnector.

[0050] S220. Based on the current disconnector image, determine the current indicator in the status recognition frame.

[0051] S230, Detect whether the current sign is a combined sign or a separate sign.

[0052] Specifically, the system can detect whether a sign is a "closed" or "separated" sign based on the text and color on the sign. For example, if the sign is green and the text says "separated," then the sign is determined to be a "separated" sign. If the sign is red and the text says "closed," then the sign is determined to be a "closed" sign.

[0053] S240. If the current indicator is a closed indicator, then check whether the current indicator is a complete closed indicator, and determine the current disconnector status based on the closed indicator detection result.

[0054] The result of the closing indicator detection can refer to whether the closing indicator is a complete indicator. The current disconnector status can include both closed and open status. For example, the closed status can be, but is not limited to, fully closed and partially closed. The open status can be, but is not limited to, fully open and partially open.

[0055] Specifically, if the current indicator is a closed indicator, it can be determined whether the current indicator is a complete closed indicator based on the current indicator and the status recognition frame. The current disconnector status is determined based on the closed indicator detection result. For example, if the current indicator is a complete closed indicator, the current disconnector status is determined to be fully closed. If the current indicator is an incomplete closed indicator, the current disconnector status is determined to be partially closed.

[0056] For example, "detecting whether the current sign is a complete sign" in S240 may include: determining the boundary distance between the current sign boundary and the state recognition box boundary in the current switch image; and determining whether the current sign is a complete sign based on the boundary distance and a preset distance threshold.

[0057] Here, "boundary" can refer to the edge of an image. "Boundary distance" can refer to the distance between the boundaries of two adjacent images. "Preset distance threshold" can refer to a pre-set distance threshold. The preset distance threshold can be the minimum boundary distance when the switch is in a fully open or fully closed state.

[0058] Specifically, the boundaries of the current indicator sign and the state recognition box in the current disconnector image are identified separately, and the boundary distance corresponding to the closed indicator sign is determined based on the identification results. The boundary distance is detected based on a preset distance threshold. If the detected boundary distance meets the preset distance threshold, it indicates that the current indicator sign boundary is completely surrounded by the state recognition box boundary, and the current indicator sign is determined to be a complete closed indicator sign; if the detected boundary distance does not meet the preset distance threshold, it indicates that the current indicator sign boundary is not completely surrounded by the state recognition box boundary, and the current indicator sign is determined to be an incomplete closed indicator sign.

[0059] It should be noted that the boundary of the current indicator sign and the boundary of the status recognition box in the current switch image can be identified separately, and the boundary distance corresponding to the sub-indicator sign can be determined based on the identification results. The boundary distance is detected based on a preset distance threshold. If the detected boundary distance meets the preset distance threshold, it indicates that the current indicator sign boundary is completely surrounded by the status recognition box boundary, and the current indicator sign is determined to be a complete sub-indicator sign; if the detected boundary distance does not meet the preset distance threshold, it indicates that the current indicator sign boundary is not completely surrounded by the status recognition box boundary, and the current indicator sign is determined to be an incomplete sub-indicator sign.

[0060] S250. If the current indicator is a sub-indicator, then check whether the current indicator is a complete sub-indicator, and determine the current disconnector status based on the sub-indicator detection result.

[0061] Among them, the sub-sign detection result can refer to whether the sub-sign is a complete sign.

[0062] Specifically, if the current indicator is a sub-indicator, it can be determined whether the current indicator is a complete sub-indicator based on the current indicator and the status recognition frame. The current disconnector status is determined based on the sub-indicator detection result. For example, if the current indicator is a complete sub-indicator, the current disconnector status is determined to be fully open. If the current indicator is an incomplete sub-indicator, the current disconnector status is determined to be partially open.

[0063] The technical solution of this invention determines the current disconnector status by detecting whether the current indicator is a closed indicator or a closed indicator, and performing an integrity check on the detected current indicator, thereby further improving the accuracy of disconnector status identification.

[0064] Based on the above technical solution, "determining whether the current sign is a complete sign based on the boundary distance and the preset distance threshold" can include: if the upper boundary distance, lower boundary distance, left boundary distance and right boundary distance are all greater than or equal to the preset distance threshold, then the current sign is determined to be a complete sign; if at least one boundary distance is less than the preset distance threshold, then the current sign is determined to be an incomplete sign.

[0065] The boundary distances can include the upper boundary distance between the upper boundary of the current sign and the upper boundary of the status recognition box, the lower boundary distance between the lower boundary of the current sign and the lower boundary of the status recognition box, the left boundary distance between the left boundary of the current sign and the left boundary of the status recognition box, and the right boundary distance between the right boundary of the current sign and the right boundary of the status recognition box.

[0066] Specifically, based on each boundary of the closing indicator in the current switch image and each boundary of the state recognition box, the upper boundary distance, lower boundary distance, left boundary distance, and right boundary distance can be determined, and these distances can be detected. If all of these distances are greater than or equal to a preset distance threshold, the current indicator is determined to be a complete closing indicator. If at least one of these distances is less than the preset distance threshold, the current indicator is determined to be an incomplete closing indicator. This method utilizes the preset distance threshold to detect the integrity of the indicator, further improving detection efficiency and accuracy.

[0067] It should be noted that the distances to the top, bottom, left, and right boundaries can be determined based on each boundary of the sub-indicator in the current switch image and each boundary of the status recognition box. These distances are then detected. If all of these distances are greater than or equal to a preset distance threshold, the current indicator is determined to be a complete sub-indicator. If at least one of these distances is less than the preset distance threshold, the current indicator is determined to be an incomplete sub-indicator.

[0068] Based on the above technical solution, S240 "determine the current disconnector status based on the detection result of the closing indicator" may include: if the current indicator is a complete closing indicator, then determine the current disconnector status as a fully closed state; if the current indicator is an incomplete closing indicator, then determine the current disconnector status as a half-closed state.

[0069] Among them, "fully closed" means that the disconnector is in a completely closed state. "Partially closed" means that the disconnector is in a partially closed state.

[0070] Specifically, if the current indicator is a complete closed indicator, the current disconnector status can be determined to be a fully closed state based on the preset correlation between the indicator and the disconnector status; if the current indicator is an incomplete closed indicator, the current disconnector status can be determined to be a partially closed state based on the preset correlation between the indicator and the disconnector status.

[0071] It should be noted that if the current indicator is a complete sub-indicator, the current disconnector status can be determined to be fully open based on the preset correlation between the indicator and the disconnector status; if the current indicator is an incomplete sub-indicator, the current disconnector status can be determined to be half open based on the preset correlation between the indicator and the disconnector status.

[0072] Based on the above technical solution, after identifying the current indicator and determining the current disconnector status, the method further includes: if the current disconnector status is half-closed or half-open, generating status abnormality information and sending the status abnormality information to the alarm device for alarm.

[0073] The abnormal status information refers to information indicating that the disconnector is in an abnormal state. For example, abnormal status information may include, but is not limited to, a partially closed or partially open state. Alarm devices may be, but are not limited to, the main controller, broadcast devices, or mobile devices.

[0074] The following are embodiments of the disconnector status identification device provided in this invention. This device and the disconnector status identification method in the above embodiments belong to the same inventive concept. For details not described in detail in the embodiments of the disconnector status identification device, please refer to the embodiments of the disconnector status identification method described above.

[0075] Example 3

[0076] Figure 3 This is a schematic diagram of a disconnector status identification device provided in Embodiment 3 of the present invention. Figure 3 As shown, the device includes: a current disconnector image acquisition module 310, a current indicator plate determination module 320, and a current disconnector status determination module 330.

[0077] The current disconnector image acquisition module 310 is used to acquire the current disconnector image corresponding to the status recognition frame of the disconnector. The disconnector includes a closing pointer and an opening pointer. When the disconnector is closed, the closing indicator connected to the closing pointer is in the status recognition frame, and when the disconnector is open, the opening indicator connected to the opening pointer is in the status recognition frame. The current indicator determination module 320 is used to determine the current indicator in the status recognition frame based on the current disconnector image. The current disconnector status determination module 330 is used to identify the current indicator and determine the current disconnector status.

[0078] The technical solution of this invention acquires the current disconnector image corresponding to the status recognition frame of the disconnector. The disconnector includes a closing pointer and an opening pointer. When the disconnector is closed, a closing indicator connected to the closing pointer is in the status recognition frame; when the disconnector is open, a closing indicator connected to the opening pointer is in the status recognition frame. Based on the current disconnector image, the indicator currently in the status recognition frame is determined, thereby automatically determining the current disconnector status. The entire recognition process requires no manual intervention, achieving automatic disconnector status recognition and improving the efficiency and accuracy of disconnector status recognition.

[0079] Optionally, the current disconnector status determination module 330 may include:

[0080] The current sign detection submodule is used to detect whether the current sign is a combined sign or a separate sign;

[0081] The completeness detection sub-model for the sign is used to detect whether the current sign is a complete sign if it is a sign that is currently closed, and to determine the current disconnector status based on the sign detection result.

[0082] The sub-model for detecting the integrity of the indicator sign is used to detect whether the current indicator sign is a complete sub-indicator sign if the current indicator sign is a sub-indicator sign, and to determine the current disconnector status based on the sub-indicator sign detection result.

[0083] Optionally, the sign integrity detection sub-model may include:

[0084] The boundary distance determination unit is used to determine the boundary distance between the current indicator boundary and the status recognition box boundary in the current disconnector image.

[0085] The sign integrity determination unit is used to determine whether the current sign is a complete sign based on the boundary distance and a preset distance threshold.

[0086] Optionally, the boundary distances include: the upper boundary distance between the upper boundary of the current sign and the upper boundary of the status recognition box, the lower boundary distance between the lower boundary of the current sign and the lower boundary of the status recognition box, the left boundary distance between the left boundary of the current sign and the left boundary of the status recognition box, and the right boundary distance between the right boundary of the current sign and the right boundary of the status recognition box.

[0087] The completeness determination of a sign is specifically used as follows: if the distances to the upper boundary, lower boundary, left boundary, and right boundary are all greater than or equal to a preset distance threshold, then the current sign is determined to be a complete sign; if at least one boundary distance is less than the preset distance threshold, then the current sign is determined to be an incomplete sign.

[0088] Optionally, the completeness detection sub-model for the closing indicator is specifically used to: if the current indicator is a complete closing indicator, then determine the current disconnector state as a fully closed state; if the current indicator is an incomplete closing indicator, then determine the current disconnector state as a half-closed state.

[0089] Optionally, the device further includes:

[0090] The alarm module is used to generate abnormal status information if the current disconnector is in a half-closed or half-open state, and then send the abnormal status information to the alarm device for alarm.

[0091] The disconnector status identification device provided in this embodiment of the invention can execute the disconnector status identification method provided in any embodiment of the invention, and has the corresponding functional modules and beneficial effects of executing the disconnector status identification method.

[0092] It is worth noting that in the embodiments of the above-mentioned disconnector status identification device, the various units and modules included are only divided according to functional logic, but are not limited to the above division, as long as the corresponding functions can be realized; in addition, the specific names of each functional unit are only for easy differentiation and are not used to limit the scope of protection of the present invention.

[0093] Example 4

[0094] Figure 4 This is a schematic diagram of a disconnector status identification system provided in Embodiment 4 of the present invention. Figure 4 As shown, the system includes: a processor, a knife switch, a crank arm, a rotating shaft, a closed indicator, an open indicator, a connecting rod, and a motor; wherein, the knife switch includes: a closed pointer and an open pointer; the closed indicator is an indicator connected to the closed pointer; the open indicator is an indicator connected to the open pointer;

[0095] The motor is connected to the knife switch via a connecting rod; the crank arm is connected to the on and off pointers via a rotating shaft;

[0096] The processor can be used to execute the switch status identification method of any embodiment of the present invention. A horizontally positioned "close" indicator is mounted on the front end of the "close" pointer. A horizontally positioned "disappear" indicator is mounted on the front end of the "disappear" pointer. The positions of the "disappear" pointer, "close" pointer, and crank arm are relatively fixed.

[0097] Specifically, see Figure 4When the processor receives a closing command from the disconnector, it controls the motor to move the connecting rod upwards, which in turn moves the crank arm upwards, causing the disconnector's internal circuit to close. Since the open and closed pointers are connected to the crank arm, they move downwards as the crank arm moves, and the closed indicator enters the status recognition frame. At this time, the current disconnector image corresponding to the status recognition frame is captured; based on the current disconnector image, the current indicator within the status recognition frame is determined; and the text on the current indicator can be used to determine whether it is a closed or open indicator. For example, if the text on the current indicator is "Closed," then the current indicator is determined to be a closed indicator. Based on each boundary of the "Closed" indicator in the current disconnector image and each boundary of the status recognition frame, the upper boundary distance, lower boundary distance, left boundary distance, and right boundary distance can be determined. These boundary distances can include the upper boundary distance between the upper boundary of the current indicator and the upper boundary of the status recognition frame, the lower boundary distance between the lower boundary of the current indicator and the lower boundary of the status recognition frame, the left boundary distance between the left boundary of the current indicator and the left boundary of the status recognition frame, and the right boundary distance between the right boundary of the current indicator and the right boundary of the status recognition frame. The upper boundary distance, lower boundary distance, left boundary distance, and right boundary distance are then detected. If all of these distances are greater than or equal to a preset distance threshold, the current indicator is determined to be a complete "Closed" indicator. If at least one of these distances is less than the preset distance threshold, the current indicator is determined to be an incomplete "Closed" indicator. If the current indicator is a complete "Closed" indicator, the current disconnector status can be determined to be a fully closed state based on the preset correlation between the indicator and the disconnector status.

[0098] It should be noted that if the current indicator is an incomplete closed indicator, the current disconnector status can be determined to be a half-closed state based on the preset correlation between the indicator and the disconnector status. Figure 5 An example diagram of a partially closed state is provided. See also... Figure 5 When the circuit breaker is not fully closed, the closing indicator will press down on the top of the status recognition frame, resulting in no complete closing indicator in the current disconnector image. This determines that the current disconnector status is half-closed and triggers an alarm.

[0099] For example, Figure 6 An example diagram of a fully open circuit breaker state is provided. See also... Figure 6When the processor receives a disconnector command, it controls the motor to move the linkage downwards, and the linkage arm moves downwards, causing the disconnector's internal circuit to disconnect. Since the open and closed pointers are connected to the linkage arm, they move upwards simultaneously with the arm's movement, and the open indicator enters the status recognition frame. At this time, the current disconnector image corresponding to the status recognition frame is captured. Based on the current disconnector image, the current indicator within the status recognition frame is determined. The text on the current indicator can be used to determine whether it is an open or closed indicator. For example, if the text on the current indicator is "open," then it is determined to be an open indicator. The distances between the upper, lower, left, and right boundaries of each boundary of the open indicator in the current disconnector image and each boundary of the status recognition frame are determined and detected. If all of these distances are greater than or equal to a preset distance threshold, then the current indicator is determined to be a complete open indicator. If at least one of the upper, lower, left, and right boundary distances is less than a preset distance threshold, the current indicator is determined to be an incomplete sub-indicator. If the current indicator is a complete sub-indicator, the current disconnector status can be determined to be fully open based on the preset correlation between the indicator and the disconnector status.

[0100] It should be noted that if the current indicator is an incomplete sub-indicator, the current disconnector status can be determined to be a half-open status based on the preset correlation between the indicator and the disconnector status. Figure 7 An example diagram of a partially open circuit is provided. See also... Figure 7 When the circuit breaker is not fully open, the indicator will cover the bottom of the status recognition frame, resulting in no complete indicator in the current circuit breaker image. This determines that the current circuit breaker status is half open and triggers an alarm.

[0101] The technical solution of this invention, through a disconnector status recognition system, can acquire the current disconnector image corresponding to the status recognition frame of the disconnector. The disconnector includes a closing pointer and an opening pointer. When the disconnector is closed, the closing indicator connected to the closing pointer is in the status recognition frame; when the disconnector is open, the opening indicator connected to the opening pointer is in the status recognition frame. Based on the current disconnector image, the system determines the current indicator in the status recognition frame, thereby automatically determining the current disconnector status. The entire recognition process requires no manual intervention, achieving automatic disconnector status recognition and improving the efficiency and accuracy of disconnector status recognition.
