It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
Example 1
Fig. 1 shows an implementation flow of a power facility field monitoring method according to an embodiment of the present invention, which is described in detail below:
Step S101, monitoring the electric power facilities in the target area by the detection device, and collecting the first operation parameter information of each electric power facility.
In this embodiment, the detection device is a device capable of detecting an operation parameter of the electric power facility, for example, a sensor or the like. The detection devices can be arranged inside and/or outside the electric power facilities, one electric power facility corresponds to at least one detection device, the detection devices corresponding to different electric power facilities are different, and the detection devices are determined according to parameters required to be detected.
For example, the detection means may comprise a resistance detection circuit, a line sequence/voltage detection circuit, an MCU singlechip, a clock/reset circuit and a communication circuit. The MCU singlechip is connected with an electric power facility needing to be monitored through a resistance detection circuit, the line sequence/voltage detection circuit is connected with the electric power facility and the MCU singlechip, the clock/reset circuit is respectively connected with the MCU singlechip, and the MCU singlechip is further connected with the communication circuit.
The resistance detection circuit is formed by sequentially connecting a high-power resistor, a thyristor and an optocoupler isolation circuit, wherein the high-power resistor is connected with an electric power facility, and the optocoupler isolation circuit is connected with an MCU (micro control Unit) singlechip. The line sequence/voltage detection circuit is an A/D sampling circuit and is connected with the electric power facility.
The A/D sampling circuit can detect the effective value, peak value and fluctuation of phase zero voltage and zero ground voltage of the electric power facility, and can also detect whether the phase line and the zero line are connected in a wrong way or are open circuit and whether the ground line is connected. The MCU singlechip controls the optocoupler isolation circuit to further control the thyristor, and controls whether the high-power resistor is connected into the circuit or not through the thyristor. When the high-power resistor is connected into the resistor, the voltage value before and after connection can be obtained through the line sequence/voltage detection circuit, and then the step-down percentage, the phase line impedance and the zero line impedance of the line are obtained.
The detection device can detect the electricity utilization condition of the electric power facility at any time, can transmit detected data in real time through the ZIGBEE network, is not limited by environment and cables, effectively analyzes the detected data, timely finds out line problems such as electric shock, electric fire and abnormal equipment operation of personnel, helps to find out the problems, helps find out and quickly locate fault positions and reasons, eliminates potential safety hazards, can trace back the detected data, helps users to realize management of data electricity utilization safety and quality, can directly take electricity through a detected circuit, does not need external power sources such as batteries, can store a large amount of data, and is convenient to use under the condition without a server.
The first operating parameter information includes, but is not limited to, a voltage, a current, a power, a rotational speed, etc. of the electric power facility, by which an operating state of the electric power facility can be reflected. For example, for a certain electric power facility, the range of the corresponding first operation parameter is substantially fixed during normal operation, so that the collected first operation parameter information may be processed according to the range, which is not described in detail herein.
Step S102, detecting the first working parameter information, and when the first working parameter information exceeds a first preset range, acquiring a current picture of a corresponding electric power facility through an image acquisition device.
Each monitoring device corresponds to one electric power facility identifier, and each electric power facility identifier corresponds to a first preset range. It can be understood that the first operating parameter information corresponding to different electric power facilities is different, so that the corresponding first preset range can be set according to the information such as the electric power facility identifier corresponding to the detection device.
The first preset range includes preset ranges of various information in the first operating parameter information. For example, the first preset range may include a first voltage preset range, a first current preset range, and the like. For different electric power facilities, the corresponding first preset ranges are different. It can be understood that the power information such as the working voltage and the working current corresponding to different power facilities are different. The first preset range may be obtained by counting historical data. For example, voltage information, current information, etc. of the electric power facility at the time of normal operation are counted, and then a first preset range is set.
Through setting up different first preset ranges to different electric power facilities, can make the monitoring to electric power facility state more reasonable, accurate and accord with actual conditions, improve the accuracy to electric power facility state monitoring.
It should be noted that, the various information in the first preset range are related as a whole, and the safety state determination may not be made on the power facility state information for one information alone. For example, the collected voltage/current information corresponding to the electric power facilities is compared with the voltage/current range in the corresponding first preset range, and when the collected voltage/current exceeds the voltage/current range in the corresponding first preset range, the state abnormality of the electric power line is judged, and the monitoring is not in accordance with the actual situation, so that the monitoring is not scientific enough.
For the above reasons, in the first preset range, a separate preset range of partial information and an overall preset range in which various information are combined together may be included. The collected partial information can be compared with the independent preset range of the information in the corresponding first preset range, and the collected various information can be compared with the integral preset range of the various information in the corresponding first preset range when needed.
Specifically, the first operating parameter information exceeding the corresponding first preset range may include the following cases:
Part of the information in the first operating parameter information exceeds the single preset range of the information in the corresponding first preset range. For example, if the voltage information acquired for a certain electric power facility exceeds an individual voltage range in a corresponding first preset range, the current picture of the corresponding electric power facility can be acquired by the image acquisition device, or if the current information acquired for a certain electric power facility exceeds an individual current range in the corresponding first preset range, the current picture of the corresponding electric power facility can be acquired by the image acquisition device.
All information in the first working parameter information exceeds the whole preset range in the corresponding first preset range. For example, when the voltage information and the current amplitude information acquired by a certain electric power facility do not exceed the respective voltage range and the respective current range in the respective first preset range, various information in the first working parameter information can be compared with the whole preset range in the first preset range, and when the preset requirement is met, the current picture of the corresponding electric power facility is acquired by the image acquisition device.
The overall preset range in the first preset range can be set according to actual conditions. For example, the independent preset range of voltage is A1-A2, the independent preset range of current is B1-B2, the overall preset range of voltage in the overall preset range is A3-A4, the overall preset range of current is B3-B4, and the overall preset range of voltage and the overall preset range of current have a correlation relationship, for example, the correlation relationship between the two can be obtained by fitting the two according to historical data.
It should be noted that, each detection device may collect first working parameter information of the electric power facility all the time according to a preset time interval, and detect the collected first working parameter information, and when the first working parameter information exceeds a first preset range, collect a current picture of the corresponding electric power facility through the image collection device.
Step S103, comparing a current picture with a preset picture, taking a corresponding electric power facility as a target electric power facility when the matching degree of the current picture and the preset picture is smaller than a threshold value, and sending first working parameter information of the target electric power facility to a server.
The preset picture is a picture when the electric power facility works normally.
Referring to fig. 2, in one embodiment, the implementation procedure of step S103 is as follows:
Step S201, extracting a plurality of first feature points of a current picture, and matching each first feature point with each second feature point of a preset picture, wherein one first feature point corresponds to one second feature point.
For each feature point of the current picture and each feature point of the preset picture, the feature points may be extracted by the same feature point extraction algorithm, for example, each feature point of the current picture may be extracted by a sift algorithm, and each feature point of the preset picture may be extracted by a sift algorithm, but not limited thereto.
It should be noted that, each feature point of the current frame corresponds to each feature point of the preset frame one by one, so that the comparison in step S202 can be performed.
And step S202, when the matching degree is smaller than the threshold value, the corresponding electric power facility is taken as a target electric power facility, and the first working parameter information of the target electric power facility is sent to the server.
Specifically, taking N first feature points extracted from the current picture, N second feature points extracted from the preset picture, and a threshold value being α (0 < α < 1) as an example, the matching logarithm of the first feature points and the corresponding second feature points is M (i.e., the M first feature points are matched with the corresponding M second feature points, 0.ltoreq.m.ltoreq.n), if M/N is greater than or equal to α, the matching degree is greater than or equal to the threshold value, and if M/N is less than α, the matching degree is less than the threshold value.
Step S104, the server monitors the state of the target electric power facility according to the received first working parameter information.
The server monitors the target electric power facility according to the received first working parameter information and the working parameter information of the normal working of the target electric power facility, so that the abnormality of the electric power facility can be found in time.
Referring to fig. 3, after step S103, the method may further include:
Step S301, collecting first operating parameter information of a target electric power facility at intervals of a preset time interval until the first operating parameter information is located in the first preset range.
In step S302, the server monitors the state of the target electric power facility according to the first operation parameter information of the target electric power facility acquired again.
Optionally, after step S104, the method may further include sending a comparison result of the current frame and the preset frame to a server, where the server stores the received first operating parameter information, the identifier of the target electric power facility, the time information, and the comparison result.
The method can further comprise the step that the server monitors the electric facilities in the same category according to the stored first working parameter information, the identification of the target electric facilities, the time information and the comparison result.
According to the electric power facility field monitoring method, the electric power facilities in the target area are monitored through the detection device, the first working parameter information of each electric power facility is collected, then the first working parameter information is detected, when the first working parameter information exceeds a first preset range, the current picture of the corresponding electric power facility is collected through the image collection device, the current picture is compared with the preset picture, when the matching degree of the current picture and the preset picture is smaller than a threshold value, the corresponding electric power facility is used as the target electric power facility, the first working parameter information of the target electric power facility is sent to the server, and the state of the target electric power facility is monitored according to the received first working parameter information by the server, so that the working state of the electric power facility can be monitored in real time, and the monitoring efficiency and accuracy of the state of the electric power facility are improved.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
