Detailed Description
The present application is described in further detail below with reference to figures 1 to 7.
The embodiment of the application discloses a method for monitoring the state of a high-voltage transmission line.
Referring to fig. 1, a method for monitoring a state of a high-voltage transmission line includes the steps of:
s101, obtaining a detection area of the high-voltage transmission line.
The detection area of the high-voltage transmission line refers to an area for monitoring the state of the high-voltage transmission line, in this embodiment, the detection area refers to a monitoring range for detecting the influence of flying creatures on the state of the high-voltage transmission line, for example, a certain area includes an area a, an area B and an area C, and the area a, the area B and the area C are all detection areas when the high-voltage transmission line in the area a, the area B and the area C is monitored.

In the detection area, the camera is used for shooting or recording a scene picture, the central control host can judge whether organisms exist on the high-voltage transmission line or not based on the images or videos shot by the camera, and when the camera adopts infrared triggering, the central control host can judge whether organisms exist on the high-voltage transmission line or not based on the shooting action of the camera.
It should be noted that, in this embodiment, the installation position of the camera on the electric power iron tower is higher than the installation position of the high-voltage transmission line, that is, the camera is installed at the top of the electric power iron tower, and the camera may adopt a fixed camera and a rotating camera, and when the fixed camera is adopted, the shooting range of the camera includes a detection area, that is, the camera is used for monitoring the detection area.
Whether the living beings exist on the high-voltage transmission line in the embodiment refers to whether the flying living beings fly above the high-voltage transmission line or whether the flying living beings stay or stand on the high-voltage transmission line.
And S103, if the biological image exists, acquiring the biological image.
If the biology exists on the high-voltage transmission line, the central control host acquires the biological image by using the camera.
If no living things exist on the high-voltage transmission line, no action is performed.
And S104, obtaining and displaying the animal type of the biological image through a preset animal identification algorithm.
The animal identification algorithm is used for identifying the animal types, the animal identification algorithm can only identify the flying creatures in the embodiment, the animal identification algorithm is obtained by training the animal images through an image processing method and a convolutional neural network, and the animal identification algorithm is widely used and is not repeated herein.
When the biological image is identified by the animal identification algorithm, the animal type can be obtained and displayed on the display screen.
And S105, controlling a preset expelling device to send out an acousto-optic prompt for expelling organisms on the high-voltage transmission line.
The expelling device can be composed of a buzzer and an LED lamp and is used for expelling flying creatures, for example, the LED lamp of the expelling device can be controlled to emit red light, and the buzzer of the expelling device is controlled to emit sound with preset frequency so as to effectively expel the flying creatures.
The implementation principle of the embodiment is as follows: when the high-voltage transmission line of the flight biology in the detection area stops or flies, the camera on the electric power iron tower acquires the biological image, the current execution main body obtains the animal type based on the biological image, and controls the preset expelling device to send out the acousto-optic prompt for expelling the flight biology, so that the probability of the flight biology causing faults to the high-voltage transmission line is reduced, and the safety of the high-voltage transmission line is effectively improved.
In step S101 of the embodiment shown in fig. 1, the detection areas may be screened based on seasons, so that it is not necessary to detect all the high voltage transmission lines, and the cost is reduced. Specifically, the embodiment shown in fig. 2 will be described in detail.
Referring to fig. 2, acquiring a detection area of a high-voltage transmission line includes the following steps:
s201, acquiring a plurality of historical fault data from a preset historical fault database.
The historical fault database is used for storing historical fault data and corresponding geographical positions, and the historical fault data refers to the date that the high-voltage transmission line in a certain area fails due to flying creatures.
S202, obtaining the corresponding geographic position of each historical fault data based on the historical fault database.
Since the historical fault data corresponds to a geographic location, the historical fault data and the corresponding geographic location may be derived based on a historical fault database.
The geographical location in this embodiment refers to a location node of the high voltage transmission line when a fault occurs, specifically, the location of each power tower may be located and stored and displayed on the display screen, and when the high voltage transmission line has a fault, the power tower closest to the location of the fault may be obtained through the obtained location of the fault, and the location of the power tower is used as the geographical location of the fault data.
And S203, obtaining the terrain corresponding to each geographic position based on a preset terrain database.
The terrain database stores the terrain where each power iron tower is positioned, and the terrain comprises plains, plateaus, hills, basins and the like.
S204, calculating the failure probability of the high-voltage transmission line of each terrain due to biological failure based on a plurality of historical failure data and a plurality of terrains.
For example, in a certain area, there are a terrain a, a terrain B and a terrain C, the total number of historical failure data is 100, the number of failure data of the high-voltage transmission line in the terrain a due to biology failure is 12, the number of failure data of the high-voltage transmission line in the terrain B due to biology failure is 48, the number of failure data of the high-voltage transmission line in the terrain C due to biology failure is 40, the failure probability of the high-voltage transmission line in the terrain a due to biology failure is 12%, the failure probability of the high-voltage transmission line in the terrain B due to biology failure is 48%, and the failure probability of the high-voltage transmission line in the terrain C due to biology failure is 40%.
For example, in a specific implementation, the terrain may be further distinguished, for example, the high-voltage transmission line is mostly close to areas such as rivers, reservoirs or low-lying wet areas on the plain due to faults caused by living beings, and may be further divided based on the areas on the terrain where faults are easy to occur.
S205, screening fault probabilities larger than a preset probability threshold value to obtain a plurality of fault terrains.
The fault terrain is the terrain corresponding to the fault probability greater than the probability threshold. Based on step S204, for example, if the probability threshold is set to 42%, the failure probability greater than the probability threshold is 48%, that is, the failure probability of the high voltage transmission line in the B terrain failing due to living things, where the B terrain is the failure terrain.
And S206, acquiring the corresponding fault geographical position of each fault terrain.
And the fault geographical position is the position node of the high-voltage transmission line in the terrain B. Namely, the fault geographical position refers to a position node of the high-voltage transmission line with higher fault probability.
And S207, determining a detection area based on the plurality of fault geographic positions.
After the position node is obtained, a detection area can be determined, and in specific implementation, the detection area refers to a monitoring area on the high-voltage transmission line.
According to the method for monitoring the state of the high-voltage transmission line, the fault probability of the high-voltage transmission line fault caused by the flying creatures is calculated firstly when different terrains are calculated, then the fault terrains corresponding to the fault probability larger than the probability threshold value are screened out, namely the fault terrains with more faults are screened out, the detection area is determined based on the fault terrains, namely all high-voltage transmission lines are not required to be monitored, the cost is effectively reduced, and meanwhile the accuracy of monitoring the high-voltage transmission line fault caused by the flying creatures is improved.
In step S207 of the embodiment shown in fig. 2, since there may be a phenomenon that a plurality of faulty geographical locations are duplicated, the faulty geographical locations need to be subjected to deduplication processing. The embodiment shown in fig. 3 will be specifically described in detail.
Referring to fig. 3, determining a detection area based on several geographical locations includes the steps of:
s301, obtaining a monitoring area where each fault geographic position is located based on a preset range database.
The range database is used for storing the monitoring area where the fault geographic position is located, namely after the fault geographic position is obtained, the monitoring area where the fault geographic position is located can be obtained based on the range database.
The monitoring area refers to an area for monitoring the high-voltage transmission line, for example, a certain area includes an area a, an area B and an area C, wherein the area a does not have the high-voltage transmission line, and only the area B and the area C have the high-voltage transmission line, so that the area B and the area C can be used as the monitoring area for monitoring the high-voltage transmission line.
S302, removing the duplicate of the plurality of monitoring areas based on a preset duplicate removal algorithm, and taking the monitoring range of all the high-voltage transmission lines of each monitoring area after the duplicate removal as a detection area.
Because the range of the monitoring area is larger than the range of the fault geographical position, the monitoring area corresponding to the fault geographical position may have repetition, and the duplicate removal processing needs to be performed on the monitoring area through a duplicate removal algorithm. Specifically, the deduplication algorithm is used to remove the same character string, so as to achieve the deduplication effect. In this embodiment, the monitoring region is a combination of character strings, so deduplication can be implemented by removing duplicate character strings.
The detection area refers to the monitoring range of all high-voltage transmission lines in the monitoring area. The monitoring range refers to a range in which the state of the high-voltage transmission line is monitored.
In the method for monitoring the state of the high-voltage transmission line, after the monitoring area where each fault geographical position is located is obtained, repeated monitoring areas may exist, so that deduplication processing needs to be performed at this time. One detection area refers to the monitoring range of all the high-voltage transmission lines in each monitoring area, and the detection area is determined to be favorable for carrying out targeted detection on the high-voltage transmission lines.
In step S102 of the embodiment shown in fig. 1, the detection of the presence of the living being on the high voltage transmission line may be performed based on a camera and an infrared detector, i.e., the infrared detector is used for detecting the presence of the living being, and the camera is used for capturing an image. The embodiment shown in fig. 4 will be specifically described in detail.
Referring to fig. 4, the camera is a mobile tracking camera; an infrared detector is arranged at one end of the electric iron tower far away from the ground;
whether there is biology on the high tension transmission line is judged based on the camera that predetermines on the electric power iron tower, including following step:
s401, judging whether the infrared detector detects the infrared signal in the detection area.
The infrared detector is a device for converting an incident infrared radiation signal into an electric signal and outputting the electric signal, and includes an infrared transmitter, a receiver, and a signal processor for detecting the presence of a living being by determining the presence of the infrared signal.
S402, if the infrared detector detects the infrared signal, acquiring a field image based on the camera.
If the infrared detector detects an infrared signal, the existence of a living being is indicated, and at the moment, the current execution main body controls the camera to acquire a field image. The camera is a mobile tracking camera, so that the camera can track and position a moving target, and in specific implementation, the mobile tracking camera can set a deflection angle, namely, the shooting range of the mobile tracking camera is limited to the area range capable of shooting the high-voltage transmission line by setting the deflection angle.
And if the infrared detector does not detect the infrared signal, no action is performed.
And S403, judging whether the live image has a living being or not based on a preset machine learning classification algorithm.
The machine learning classification algorithm is used for judging whether flying creatures exist in the images, the machine learning classification algorithm in the embodiment adopts an SVM (support vector machine), namely a support vector machine, and is a two-classification model, namely an image classifier is realized by using an HOG + SVM algorithm and an OpenCV, the effect of judging whether the images are animals is realized by training the classifier, and then whether the live images exist in the field is judged by judging whether the live images are animals.
And S404, if the high-voltage transmission line exists, determining that the living things exist on the high-voltage transmission line.
If the live images contain organisms, judging that flying organisms exist on the high-voltage transmission line.
And if the live image does not have the creature, judging that the creature does not exist on the high-voltage transmission line.
According to the state monitoring method for the high-voltage transmission line, the camera adopts the mobile tracking camera, so that the mobile flying creatures can be conveniently tracked, when the infrared detector detects an infrared signal, the camera can shoot a live image, at the moment, the current execution main body judges whether the live image has creatures or not based on a machine learning classification algorithm, and the arrangement of the camera and the infrared detector is beneficial to increasing the accuracy of judging whether the flying creatures stay or fly on the high-voltage transmission line, so that the safety of the high-voltage transmission line is conveniently improved.
After step S404 of the embodiment shown in fig. 4, after determining that the living being exists on the high-voltage transmission line, the living being may be located so that the worker can more intuitively know the location of the living being on the high-voltage transmission line. Specifically, the embodiment shown in fig. 5 will be described in detail.
Referring to fig. 5, a cloud deck is further arranged at one end, far away from the ground, of the electric iron tower, a camera is arranged on the cloud deck, and a laser radar is further arranged on the cloud deck;

s501, positioning the living beings based on the laser radar.
The laser radar is a radar using a laser as a radiation source, and is used for detecting characteristic quantities such as a position and a speed of a target by emitting a laser beam. The working principle of the radar target positioning system is that a detection signal is transmitted to a target, and then the received signal reflected from the target is compared with the transmitted signal to obtain the distance between the radar and the target, so that the target is positioned. The laser radar comprises a laser transmitter, an optical receiver, a turntable, an information processing system and the like, wherein the laser changes electric pulses into optical pulses to be transmitted out, and the optical receiver restores the optical pulses reflected from a target into the electric pulses to be transmitted to a display.
Because the camera is the mobile tracking camera, so when the mobile tracking camera rotates, drive the cloud platform and rotate, and then drive lidar and rotate, laser radar is unanimous with the rotation direction of mobile tracking camera promptly, and in the concrete implementation, laser radar's transmission direction is towards high tension transmission line, and the shooting direction of camera also is towards high tension transmission line, and when there is the flight biology on high tension transmission line, laser radar fixes a position the flight biology promptly.
And S502, generating and displaying positioning information.
The positioning information refers to the distance between the living being and the laser radar, and the distance between the living being and the laser radar can be approximate to the distance between the living being and the electric power iron tower corresponding to the holder where the laser radar is located because the laser radar is located on the holder located on the electric power iron tower.
According to the method for monitoring the state of the high-voltage transmission line, the laser radar is used for positioning the living beings, so that background workers can visually see the positioning information of the living beings, and the workers can timely and effectively process the positioning information.
In step S102 of the embodiment shown in fig. 2, the camera may be an infrared trigger camera, that is, when the camera detects an infrared signal, an image is taken. Specifically, the embodiment shown in fig. 6 will be described in detail.

The infrared trigger camera comprises an active infrared trigger camera and a passive infrared trigger camera, the active infrared trigger camera comprises an infrared transmitter, a receiver, a shooting camera and the like, the working principle is that the transmitter transmits infrared beams and is over against a corresponding receiving window on the receiver, when a moving object passes through between the transmitter and the receiver, the infrared beams are cut off, and at the moment, the infrared trigger camera shoots a photo; the passive infrared trigger camera comprises an infrared sensor, a control circuit board, a photographing camera, a power supply system and a shell, and has the working principle that when a warm-blooded animal passes through the infrared trigger camera from the front, the temperature difference caused by the body temperature of the animal and the ambient temperature causes the change of heat around the camera, and after the change of the temperature is received by the infrared sensor, a pulse signal is generated to trigger the infrared trigger camera to photograph.
In this embodiment, a passive infrared trigger camera is used. That is, if the instantaneous image is acquired, it is determined that a living being exists.
If the instantaneous image is not acquired, it is judged that no living things exist.
And S602, if the instantaneous image is acquired, judging that the living things exist on the high-voltage transmission line.

After step S404 of the embodiment shown in fig. 4 or step S602 of the embodiment shown in fig. 6, that is, after it is determined that a living being exists on the high-voltage transmission line, it may be determined whether the high-voltage transmission line fails, and based on the number of times of failures of the high-voltage transmission line due to the living being in each season of the year, a season failure visualization chart is obtained, so as to facilitate intuitive analysis by a worker. Specifically, the embodiment shown in fig. 7 will be described in detail.
Referring to fig. 7, after determining the presence of a living being on the high voltage power transmission line, the method includes the steps of:
