Description

Technical Field

[0001] This invention relates to the field of power equipment testing, and in particular to a method for identifying power testing interface switches. Background Technology

[0002] In power systems, the detection of power switches is widely used. It can indicate the operating status of power lines in real time and troubleshoot power faults. When a fault occurs in the power system, it is usually done manually by using detection devices to inspect and track the location and status of the power fault. This method is inefficient and lacks flexibility.

[0003] For example, a "power switchgear switch status image recognition system" disclosed in Chinese patent literature cannot change the current state of the power detection interface switch during the detection process, resulting in the inability to detect it. Furthermore, it requires continuous manual plugging and unplugging of the power detection interface switch, which is inefficient and can easily damage the power detection interface switch, making the overall process inconvenient. Summary of the Invention

[0004] This invention aims to overcome the limitations of existing technologies where power detection interface switches cannot be detected in real time and their switching states cannot be changed promptly after detection. It provides a power detection interface switch identification method that enables real-time detection of the switch interface state and allows for control of the power detection interface switch during the detection process. The entire process is flexible and convenient, enabling remote switch detection and control, improving detection efficiency, and offering high flexibility.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] A method for identifying a power detection interface switch, characterized by comprising the following steps:

[0007] Step S1: Connect the electrical signals of the M electrical devices to be tested, number them, and connect them to the testing device.

[0008] Step S2: Number the N power detection interface switches on each power device to be tested;

[0009] Step S3: Perform the first round of scanning and identification of the power detection interface switch to be tested, confirm the closed state of the switch, and mark the power detection interface switch to be tested that is initially closed with a signal mark;

[0010] Step S4: Force the unclosed power detection interface switch to be tested in step S3 to be closed;

[0011] Step S5: Perform a second round of scanning and identification on the forcibly closed power detection interface switch to be tested;

[0012] Step S6: Complete the scanning and identification of the power detection interface switches to be tested, restore all the power detection interface switches to the state before the first round of scanning and identification, and remove the signal marks made in steps S3 and S5.

[0013] By performing a first round of scanning and identification on the power detection interface switch, fault diagnosis or functional testing of the power detection interface switch is carried out, reducing misjudgments after the detection is completed. After the first round of scanning and identification, the open switch is marked, and the second round of scanning and identification only targets the marked switch, thereby improving detection efficiency and enabling remote control of the power detection switch status.

[0014] Preferably, step S1 includes the following steps:

[0015] Step S1-1: After completing the electrical signal connection of the power device to be tested, connect the testing device to one of the power devices to be tested;

[0016] Step S1-2: Mark the electrical device to be tested that is directly connected to the detection device as A1, and at the same time identify the electrical devices to be tested that are adjacent to the electrical device to be tested marked as A1.

[0017] Step S1-3: Mark the adjacent electrical device to be tested as A2 as described in step S1-2, reduce the electrical connection signal between A1 and A2, and at the same time identify the signal of the electrical device to be tested connected to the electrical device to be tested marked as A2.

[0018] Step S1-4: Repeat step S1-3 until the last electrical device to be tested is marked as M, then complete the numbering of all electrical devices to be tested and end the numbering process.

[0019] Preferably, the maximum number of connections between the electrical devices to be tested is K, and K≤2. The electrical device to be tested, numbered A1, is connected to the testing device, and the electrical device to be tested, numbered AM, is only connected to AM-1.

[0020] Preferably, step S2 includes the following steps:

[0021] Step S2-1: The detection device connects to the electrical device to be detected, completes the numbering of the electrical device to be detected, scans the first identified power detection interface switch signal and forms the image to be identified A;

[0022] Step S2-2: Determine the switching state of the first identified power detection interface switch and match it with the image to be identified A in step S2-1;

[0023] Step S2-3: If the first identified power detection interface switch is closed, then the image to be identified A is used as the criterion for judging the switch status of subsequent power detection interface switches. The first identified power detection interface switch is marked as B1, and the subsequent identified power detection interface switches are marked as B2, B3, B4...BN according to the scanning order.

[0024] Step S2-4: If the first identified power detection interface switch is in an open state, then different identification images B are formed based on the identification image A. The identification image B is used as the judgment standard for the switching state of subsequent power detection interface switches. The first identified power detection interface switch is marked as B1, and the subsequent identified power detection interface switches are marked as B2, B3, B4...BN according to the scanning order.

[0025] Step S2-5: Complete the numbering of the power detection interface switch and perform the power detection interface switch identification and scanning process.

[0026] Preferably, in step S3-1: the detection device identifies and scans all power detection interface switches marked BX (X is 1, 2, 3, ... N), and completes the feedback of the switch status signals of all power detection interface switches;

[0027] Step S3-2: While scanning and identifying the power detection interface switch, compare the scanned image of each switch with the image to be identified A or image to be identified in steps S2-2 and S2-3 to determine the current switching status of the power detection interface switch.

[0028] Step S3-3: When the detected power detection interface switch is closed, the detection device records the switch status and sends it back to the signal receiving device and the information storage device;

[0029] Step S3-4: When the detected power detection interface switch is in an open state, the detection device records the switch state and sends it back to the signal receiving device and the information storage device. At the same time, it sends a control signal to force the currently detected switch into a closed state, skips the currently detected power detection interface switch, and marks the power detection interface switch with a digital label C, changing the current power detection interface switch label from BX to BX-C.

[0030] Step S3-5: Complete the first scan and identification of all power detection interface switches, and send the status of the power detection interface switches scanned in the first scan to the information storage device, thus ending the first scan process.

[0031] By marking the power detection interface switches that did not close after the first scan, duplicate scanning is prevented during the second scan, thus reducing the waste of power resources and improving the detection efficiency of power detection interface switches.

[0032] Preferably, step S5 includes the following steps:

[0033] Step S5-1: Perform a second scan. The detection device identifies and scans the power detection interface switches that were not closed in the first scan according to the mark BX-C in step S3.

[0034] Step S5-2: Complete the second scan and send a feedback signal to the information receiving device and the information storage device.

[0035] Preferably, step S6 includes the following steps:

[0036] Step S6-1: Complete the second scan and receive the power detection interface switch position marked BX-C in step S3, which is stored in the information storage device.

[0037] Step S6-2: Based on the received marking information, restore the power detection interface switch marked BX-C to its state before the first scan and identification, and complete the entire scan and identification process;

[0038] Step S6-3: Save the data generated by the first and second scanning identification processes to the information storage device, and remove the BX-C mark made on the power detection interface switch that was not closed in the first scan before the second scan.

[0039] After the detection is completed, the marking of the additionally marked power detection interface switches will be removed, and the data records from the first and second scanning and identification processes will be saved to the information storage device for historical data comparison in subsequent scanning and identification processes of power detection interface switches. At the same time, in subsequent scanning and identification processes, the current images to be detected, A and B, can be directly used, which can further reduce the investment of scanning and identification storage resources for power detection interface switches, improve resource utilization, and improve the identification efficiency of subsequent power detection interface switches.

[0040] Preferably, the data records generated by the identification process include the status flag of the power detection interface switch, image A to be identified, and image B to be identified.

[0041] Therefore, the beneficial effects of the present invention are as follows:

[0042] By performing a first round of scanning and identification on the power detection interface switch and a second round of scanning and identification, the power detection interface switch can be used for fault diagnosis or functional testing, reducing misjudgments after the test. After the first round of scanning and identification, the open switch is marked, and the second round of scanning and identification only targets the marked switch, improving the detection efficiency and enabling remote control of the power detection switch status.

[0043] By marking the power detection interface switches that did not close after the first scan, we can prevent repeated scanning during the second scan, thus reducing the waste of power resources and improving the detection efficiency of power detection interface switches.

[0044] In subsequent scanning and recognition processes, directly using the current images A and B can further reduce the investment in scanning and recognition storage resources for power detection interface switches, improve resource utilization, and increase the recognition efficiency of subsequent power detection interface switches.

[0059] Step S1-2: Mark the electrical device to be tested that is directly connected to the detection device as A1, and at the same time identify the electrical devices to be tested that are adjacent to the electrical device to be tested marked as A1.

[0060] Step S1-3: Mark the adjacent electrical device to be tested as A2 as described in step S1-2, reduce the electrical connection signal between A1 and A2, and at the same time identify the signal of the electrical device to be tested connected to the electrical device to be tested marked as A2.

[0061] Step S1-4: Repeat step S1-3 until the last electrical device to be tested is marked as M, then complete the numbering of all electrical devices to be tested and end the numbering process.

[0062] The maximum number of connections between the electrical devices to be tested is K, and K≤2. The electrical device to be tested, numbered A1, is connected to the testing device, and the electrical device to be tested, numbered AM, is only connected to AM-1.

The first identified power detection interface switch is marked as B1, and the subsequent identified power detection interface switches are marked as B2, B3, B4...BN according to the scanning order.

[0067] Step S2-4: If the first identified power detection interface switch is in an open state, then different identification images B are formed based on the identification image A. The identification image B is used as the judgment standard for the switching state of subsequent power detection interface switches. The first identified power detection interface switch is marked as B1, and the subsequent identified power detection interface switches are marked as B2, B3, B4...BN according to the scanning order.

[0068] Step S2-5: Complete the numbering of the power detection interface switch and perform the power detection interface switch identification and scanning process.

[0069] Step S3-1: The detection device identifies and scans all power detection interface switches marked BX (X is 1, 2, 3, ... N), and completes the feedback of the switch status signals of all power detection interface switches;

[0070] Step S3-2: While scanning and identifying the power detection interface switch, compare the scanned image of each switch with the image to be identified A or image to be identified in steps S2-2 and S2-3 to determine the current switching status of the power detection interface switch.

[0071] Step S3-3: When the detected power detection interface switch is closed, the detection device records the switch status and sends it back to the signal receiving device and the information storage device;

[0072] Step S3-4: When the detected power detection interface switch is in an open state, the detection device records the switch state and sends it back to the signal receiving device and the information storage device. At the same time, it sends a control signal to force the currently detected switch into a closed state, skips the currently detected power detection interface switch, and marks the power detection interface switch with a digital label C, changing the current power detection interface switch label from BX to BX-C.

[0073] Step S3-5: Complete the first scan and identification of all power detection interface switches, and send the status of the power detection interface switches scanned in the first scan to the information storage device, thus ending the first scan process.

[0074] By marking the power detection interface switches that did not close after the first scan, duplicate scanning is prevented during the second scan, thus reducing the waste of power resources and improving the detection efficiency of power detection interface switches.

[0075] Step S5 includes the following steps:

At the same time, in subsequent scanning and identification processes, the current images to be detected, A and B, can be directly used, which can further reduce the investment of scanning and identification storage resources for power detection interface switches, improve resource utilization, and improve the identification efficiency of subsequent power detection interface switches.

[0083] The data records generated during the identification process include the status markers of the power detection interface switch, image A to be identified, and image B to be identified.

[0084] like Figure 2 As shown, the image to be recognized, either A or B, is divided into 6 regions. Horizontal and vertical lines are used to divide the template image into multiple rectangular blocks to be recognized. These 6 blocks are labeled 1 to 6 from left to right and top to bottom. Figure 2The position of the image block to be identified in the original image A or image B to be identified corresponds to the corresponding power detection interface switch state. If the power detection interface switch state is closed, then each color block in the image A to be identified is marked with color blocks based on the image A to be identified as the standard, and the power detection interface switch that has completed the first scan in step S3 is marked with color blocks and the switch state is judged.
