[0037] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0038] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0039] Embodiment 1

[0040] Figure 1 The implementation process of the on-site monitoring method for electric power facilities provided by the first embodiment of the present invention is shown, and is described in detail as follows:

[0041] Step S101: monitor the power facilities in the target area through a detection device, and collect first operating parameter information of each power facility.

[0042] In this embodiment, the detection device is a device capable of detecting the working parameters of the power facility, such as a sensor, etc. The detection device can be arranged inside and / or outside the power facility, and one power facility corresponds to at least one detection device. Different power facilities correspond to different detection devices, which are determined according to the parameters to be detected.

[0043] For example, the detection device may include a resistance detection circuit, a line sequence / voltage detection circuit, an MCU microcontroller, a clock / reset circuit, and a communication circuit. The MCU microcontroller is connected to the power facilities to be monitored through the resistance detection circuit, the line sequence / voltage detection circuit is connected to the power facilities and the MCU microcontroller, the clock / reset circuit is connected to the MCU microcontroller respectively, and the MCU microcontroller is also connected to the communication circuit.

[0044] The resistance detection circuit is composed of a high-power resistor, a thyristor and an optocoupler isolation circuit connected in sequence. The high-power resistor is connected to the power facility, and the optocoupler isolation circuit is connected to the MCU. The line sequence / voltage detection circuit is an A / D sampling circuit connected to the power facility.

[0045] The A / D sampling circuit can detect the effective value, peak value, fluctuation of the phase zero voltage and the effective value, peak value, fluctuation of the neutral-to-ground voltage of the power facility. It can also detect whether the phase line and the neutral line are connected incorrectly or open, and whether the ground line is connected. The MCU controls the optocoupler isolation circuit, and then controls the thyristor, and controls whether the high-power resistor is connected to the circuit through the thyristor. When the high-power resistor is connected to the resistor, the voltage value before and after the connection can be obtained through the line sequence / voltage detection circuit, and then the voltage reduction percentage, phase line impedance and neutral line impedance of the line can be obtained.

[0046] The detection device can detect the power usage status of power facilities at any time, and can transmit the detected data in real time through the ZIGBEE network. It is not restricted by the environment and cables, and can effectively analyze the detection data to promptly discover line problems that may cause electric shock, electrical fires, abnormal equipment operation, etc. It helps to discover problems, help identify and quickly locate the fault location and cause, eliminate safety hazards, and can trace back detection data to help users achieve digital power safety and quality management. It can directly draw power from the circuit under test without the need for external power supplies such as batteries, and can store large amounts of data, making it convenient to use without a server.

[0047] The first operating parameter information includes but is not limited to the voltage, current, power, speed, etc. of the power facility, and the first operating parameter information can reflect the operating state of the power facility. For example, for a certain power facility, the range of the first operating parameter corresponding to its normal operation is basically fixed, so the collected first operating parameter information can be processed according to the range, which will not be described in detail here.

[0048] Step S102: detecting the first operating parameter information, and when the first operating parameter information exceeds a first preset range, capturing a current image of the corresponding power facility through an image capture device.

[0049] Each monitoring device corresponds to an electric power facility identifier, and each of the electric power facility identifiers corresponds to a first preset range. It is understandable that the first operating parameter information corresponding to different electric power facilities is not the same, so the corresponding first preset range can be set according to the electric power facility identifier and other information corresponding to the detection device.

[0050] The first preset range includes preset ranges of various information in the first working parameter information. For example, the first preset range may include a first voltage preset range, a first current preset range, etc. For different power facilities, the corresponding first preset ranges are not the same. It is understandable that different power facilities correspond to different power information such as working voltage and working current. Among them, the first preset range can be obtained by statistically analyzing historical data. For example, the voltage information, current information, etc. of the power facility during normal operation are statistically analyzed, and then the first preset range is set.

[0051] By setting different first preset ranges for different power facilities, the monitoring of the power facility status can be made more reasonable, accurate and in line with the actual situation, thereby improving the accuracy of the power facility status monitoring.

[0052] It should be noted that the various information in the first preset range are interrelated as a whole, and a single piece of information may not be able to make a safe state judgment on the power facility status information. For example, if the collected voltage / current information corresponding to the power facility is compared with the voltage / electricity range in the corresponding first preset range, and when the collected voltage / electricity information exceeds the voltage / electricity range in the corresponding first preset range, it is determined that the power line state is abnormal, which is not in line with the actual situation and the monitoring is not scientific enough.

[0053] Based on the above reasons, the first preset range may include a separate preset range of partial information and an overall preset range of various information combined together. The collected partial information may be first compared with the separate preset range of the information in the corresponding first preset range, and the collected various information may be compared with the overall preset range of various information in the corresponding first preset range when necessary.

[0054] Specifically, the first operating parameter information exceeds the corresponding first preset range and may include the following situations:

[0055] Part of the information in the first working parameter information exceeds the separate preset range of the information in the corresponding first preset range. For example, if the voltage information collected from a certain power facility exceeds the separate voltage range in the corresponding first preset range, the current screen of the corresponding power facility can be collected through the image acquisition device; or, if the current information collected from a certain power facility exceeds the separate current range in the corresponding first preset range, the current screen of the corresponding power facility can be collected through the image acquisition device.

[0056] All information in the first working parameter information exceeds the overall preset range in the corresponding first preset range. For example, if the voltage information and current amplitude information collected for a certain power facility do not exceed the individual voltage range and individual current range in the corresponding first preset range, the various information in the first working parameter information can be compared with the overall preset range in the first preset range, and the current picture of the corresponding power facility can be collected through the image acquisition device when the preset requirements are met.

[0057] The overall preset range in the first preset range can be set according to actual conditions. For example, the individual preset range of voltage is A1-A2, and the individual preset range of current is B1-B2; and the overall preset range of voltage in the overall preset range is A3-A4, and the overall preset range of current is B3-B4. There is an association between the overall preset range of voltage and the overall preset range of current. For example, the association between the two can be obtained by fitting the two according to historical data.

[0058] It should be noted that each detection device can collect the first working parameter information of the power facility at a preset time interval and detect the collected first working parameter information. When the first working parameter information exceeds the first preset range, the current picture of the corresponding power facility is captured by the image acquisition device.

[0059] Step S103, comparing the current picture with the preset picture, and when the matching degree between the current picture and the preset picture is less than a threshold, taking the corresponding power facility as the target power facility, and sending the first working parameter information of the target power facility to the server.

[0060] The preset picture is a picture when the electric power facility is working normally.

[0061] See also Figure 2 In one embodiment, the implementation process of step S103 is as follows:

[0062] Step S201, extracting a plurality of first feature points of the current picture, and matching each of the first feature points with each of the second feature points of the preset picture; one first feature point corresponds to one second feature point.

[0063] Among them, each feature point of the current picture and each feature point of the preset picture can be extracted by the same feature point extraction algorithm. For example, each feature point of the current picture can be extracted by the SIFT algorithm, and each feature point of the preset picture can also be extracted by the SIFT algorithm, but it is not limited to this.

[0064] It should be noted that each feature point of the current picture corresponds to each feature point in the preset picture one by one, so that the comparison in step S202 can be performed.

[0065] Step S202: When the matching degree is less than the threshold, the corresponding power facility is used as the target power facility, and the first operating parameter information of the target power facility is sent to the server.

[0066] Specifically, taking the extraction of N first feature points from the current picture and N second feature points from the preset picture with a threshold of α (0<α<1) as an example, the number of matching pairs of the first feature points and the corresponding second feature points is M (that is, M first feature points match the corresponding M second feature points, 0≤M≤N). If M / N is greater than or equal to α, the matching degree is greater than or equal to the threshold. If M / N is less than α, the matching degree is less than the threshold.

[0067] Step S104: the server monitors the status of the target power facility according to the received first operating parameter information.

[0068] The server monitors the target power facility based on the received first working parameter information and the working parameter information of the normal operation of the target power facility, so as to timely discover abnormalities in the power facility.

[0069] See also Figure 3 After step S103, the method may further include:

[0070] Step S301: collecting first operating parameter information of a target electric power facility at a preset time interval until the first operating parameter information is within the first preset range.

[0071] Step S302: The server monitors the state of the target power facility according to the first operating parameter information of the target power facility collected again.

[0072] Optionally, after step S104, the method may further include: sending a comparison result between the current screen and the preset screen to a server, and the server stores the received first working parameter information, the identifier of the target power facility, the time information and the comparison result.

[0073] As an implementable embodiment, the method may further include: the server monitoring the power facilities of the same category according to the stored first working parameter information, the identification of the target power facility, the time information and the comparison result.

[0074] The above-mentioned on-site monitoring method of electric power facilities monitors the electric power facilities in the target area through a detection device, collects the first working parameter information of each electric power facility, and then detects the first working parameter information. When the first working parameter information exceeds a first preset range, the current picture of the corresponding electric power facility is collected through an image acquisition device, and the current picture is compared with the preset picture. If the matching degree between the current picture and the preset picture is less than a threshold, the corresponding electric power facility is used as the target electric power facility, and the first working parameter information of the target electric power facility is sent to the server. The server monitors the status of the target electric power facility according to the received first working parameter information, so that the working status of the electric power facility can be monitored in real time, thereby improving the monitoring efficiency and accuracy of the status of the electric power facility.

[0075] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
