Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The visual monitoring device for the power transmission line realizes remote inspection of a power transmission line channel corridor, reduces inspection pressure of power personnel by increasing the ground, and improves inspection efficiency. The hidden danger of the main monitoring and shooting of the visible monitoring and shooting device of the power transmission line mainly comprises construction machinery, such as an excavator, a crane, trees, buildings and the like.

The equipment (as shown in fig. 2) for monitoring the hidden trouble of the power transmission line is usually installed in different places to take hidden trouble pictures from different angles. By splicing the hidden trouble pictures at different angles, the hidden trouble of the power transmission line can be accurately and completely determined by splicing the pictures. However, the internal crystal oscillators of the devices are affected by factors such as environment and the like, the time of each device may not be uniform, signal transmission delay and the like, and the time for the devices to shoot the hidden danger pictures is not synchronous, so that the hidden danger is not accurately identified.

Based on this, the embodiment of the application provides a method and equipment for monitoring hidden dangers of a power transmission line, which are used for solving the problems that time is asynchronous between the hidden danger monitoring equipment of the power transmission line, and hidden dangers cannot be accurately identified.

Various embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application provides a method for monitoring hidden troubles of a power transmission line, which is used in a monitoring device 200 for monitoring the hidden troubles of the power transmission line, wherein the monitoring device 200 is erected on a tower of the power transmission line, the monitoring device 200 (as shown in fig. 2) comprises a controller 201, a GPS module 202 connected with the controller 201, and an external Real-Time Clock RTC203 connected with the controller 201, and the RTC is an english abbreviation of a Real-Time Clock. As shown in fig. 1, the method may include steps S101-S105:

s101: the controller acquires GPS correction time through the GPS module so as to correct the time of a system clock of the controller and an external real-time clock RTC connected with the controller through the GPS correction time;

s102: the controller determines whether the time difference between a system clock of the controller and a corresponding external RTC is smaller than a preset threshold value;

s103: the controller generates an image shooting instruction under the condition that the time difference is smaller than a preset threshold value so as to obtain an image to be detected of the hidden danger of the power transmission line;

s104: the controller identifies hidden danger information in the image to be detected;

s105: the controller generates a synchronous shooting instruction based on the hidden danger information, and sends the synchronous shooting instruction to the plurality of associated devices of the controller, so that the plurality of hidden danger images of the hidden danger information at the same time and different shooting angles are obtained through the associated devices.

Wherein, S101: the controller acquires GPS correction time through the GPS module so as to correct the time of a system clock of the controller and an external real-time clock RTC connected with the controller through the GPS correction time. The method comprises the following specific steps:

in the embodiment of the application, the controller is a CPU of the shooting device, such as a camera, and the like, and is connected with a GPS module, and the GPS module can locate the current position and acquire real-time data. The GPS module can automatically acquire GPS correction time under the condition that the shooting equipment is started to operate or is timed. For example, the GPS module may take the GPS correction time six points in the morning each day.

In addition, the controller can store the GPS correction time in a corresponding memory in advance, and the GPS correction time is convenient to call. An external Real Time Clock (RTC) is an external RTC chip connected to the controller, and the external RTC has higher timing precision than a system Clock of the controller.

In the embodiment of the application, because the crystal oscillator of the device is easily affected by environmental conditions, the clock of the device has errors, and the application can correct the system clock by executing the following method. The method comprises the following specific steps:

first, the controller corrects the time interval of the timing unit of the controller based on the GPS second pulse transmitted from the GPS module.

After acquiring the GPS correction time, the GPS module may send a GPS second pulse, which is a pulse signal generated by the GPS module once a second, to a Controller (CPU) through a connected GPS pin. The controller may correct the timing unit, i.e., the timer, within the controller by GPS second pulses for a time interval, e.g., 1 millisecond timer within 1 second, the time interval between pulses generated by the timer.

In one embodiment of the present application, the time interval of the timing unit is corrected by performing the following method, as shown in fig. 3, specifically including S301 to S303:

s301: the controller determines a second number recorded by a corresponding timing unit of the controller under the condition that the GPS module sends a first number of GPS second pulses;

s302: the controller calculates the recording error of the timing unit within the time corresponding to the GPS pulses of the first number according to the first number, the second number and a preset formula;

s303: the controller corrects the time interval of the timing unit according to the recording error.

S301: the controller determines a second number recorded by a corresponding timing unit of the controller in the event that the GPS module transmits a first number of GPS second pulses. The method comprises the following specific steps:

wherein the second number is the number of one millisecond corresponding to the first number of GPS second pulses.

The controller determines a first number

Then the controller determines that the first quantity is being received

The number of one millisecond recorded by the timing unit as the second number during the GPS second pulse

。

For example, the first number of GPS second pulses

=10, i.e. under the GPS timing system, ten seconds have elapsed, and the controller then determines a second number of generated pulses, e.g. 9000, i.e. 9000 milliseconds, recorded by the timing unit (millisecond timer) within the ten seconds.

S302: and the controller calculates the recording error of the timing unit within the time corresponding to the first number of GPS pulses according to the first number, the second number and a preset formula.

Wherein the predetermined formula comprises a relation between the first number, the second number and the recording error.

The preset formula is as follows:

wherein the content of the first and second substances,

in order to record the error in a timing unit,

in the form of a first number of bits,

is the second number. The formula can be expressed as

Within seconds, the recording error of the recording time of the timing unit. For example

=10，

=9000, then

=100, i.e. within one second, the timing unit compares with the GPS module, which can generate a timing error of 100 milliseconds.

The controller may correct the time interval of the timing unit in dependence on the recording error, i.e. adjust the number of pulses of the timing unit in 1 second, which, as in the above example, may be increased by 100 millisecond pulses in 1 second.

The controller then time-corrects the system clock by the corrected time interval and the GPS corrected time.

After the controller corrects the time interval of the timing unit, the controller may extract the GPS corrected time stored in the memory and adjust the system clock to the GPS corrected time. Meanwhile, the controller can clear the data recorded by the timing unit to restart the timing by the corrected time interval, and the timing process is as follows: when the second pulse is generated in the controller, the system clock is increased by 1 second on the basis of the GPS correction time.

In one embodiment of the present application, after correcting the time of the system clock according to the GPS module, the present application may correct the time of the external RTC by performing the following method. The method comprises the following specific steps:

after the time correction of the system clock of the controller, the whole second correction time of the system clock is transmitted to the external RTC through an integrated circuit bus between the controller and the external RTC to synchronize the external RTC with the time of the system clock, so as to correct the time of the external RTC connected to the controller.

The controller is connected with the external RTC through an Inter-Integrated Circuit (IIC), and the controller sends a signal for synchronizing the time of the external RTC through the IIC, wherein the signal is a corrected time signal of the system clock of the controller at the time of a whole second. For example, 06:00:00 for a whole second, the controller sends a time signal of 06:00:00 to the external RTC, so as to correct the time of the external RTC to 06:00:00, and during actual use, the unit of time may be in the order of milliseconds or even microseconds, which is not specifically limited in this application.

In an embodiment of the present application, since the pulse time intervals of the external RTC and the system clock are in actual use, there may be inconsistency due to the influence of environmental conditions, resulting in time asynchronization between the two. Therefore, the controller reads the accurate time and corrects the system time by the following method. Specifically, the method comprises the following steps:

when the controller receives an RTC second pulse sent by an external RTC, the whole second correction time T1 of the system time is written into the external RTC, then when the controller receives the next RTC second pulse from the external RTC, the controller reads the time T2 of the external RTC, the controller subtracts the time T1 from the time T2 to obtain a difference value T3, and subtracts 1 second from T3 to obtain a communication delay between the controller and the external RTC

= T3-1. When the controller reads the time of the external RTC, the communication delay is subtracted from the read time, so that the accurate external RTC time can be determined, and the system clock of the controller can be corrected according to the external RTC time after the communication delay is subtracted.

It should be noted that, when the GPS module is started at a fixed time or the GPS module is powered by a device corresponding to the controller, the GPS module can perform time correction on the system clock of the controller. If the GPS module does not correct the time of the system clock of the controller, the controller cannot correct the time of the external RTC.

Because the GPS module has short service time and does not need to be started all the time, the power consumption of the equipment is monitored in order to reduce the corresponding hidden danger of the controller.

Therefore, in an embodiment of the present application, after correcting the system clock of the controller and the time of the external RTC connected to the controller, the following method may be performed, specifically as follows:

the controller closes the power control pin of the GPS module, determines the timing starting time of the power control pin of the GPS module, starts the GPS module according to the timing starting time, and corrects the system clock of the controller and the time of an external RTC connected with the controller.

By closing the power supply control pin of the GPS module, the electric quantity consumption of the monitoring equipment for the hidden danger of the power transmission line can be reduced.

S102: the controller determines whether a time difference between a system clock of the controller and a corresponding external RTC is less than a preset threshold.

In this embodiment, the controller may determine a time difference between the system clock and the external RTC in real time, and determine whether the time difference is smaller than a preset threshold. The preset threshold is used for determining whether the time of the system clock is synchronous with the time of the external RTC, and the preset threshold can be obtained by averaging the time differences between the system clock and the external RTC in the actual use process of the plurality of hidden danger monitoring devices, or can be set manually, for example, 10 milliseconds, 20 milliseconds, and the like.

S103: and the controller generates an image shooting instruction under the condition that the time difference is smaller than a preset threshold value so as to acquire the image to be detected of the hidden danger of the power transmission line.

The controller can determine whether a system clock and an external RTC of the equipment for monitoring the hidden danger of the power transmission line are time-synchronized, namely, the time difference is smaller than a preset threshold value. Under the condition of time synchronization, the controller can generate an image shooting instruction to control the monitoring equipment to shoot to obtain an image to be detected.

And under the condition that the time difference is larger than a preset threshold value, the controller acquires the time data of the external RTC.

Wherein the time data includes: pulse interval, current time.

The controller takes the time data of the external RTC as the corresponding calibration value of the system clock so as to adjust the time and the pulse of the system clock to the calibration value.

The controller may acquire time data of the external RTC to calibrate the system clock. For example, the timing of the system clock is 18:00:26, the time data of the external RTC is 18:00:36, the time difference is 10 seconds, if the preset threshold is 10 milliseconds, the system clock needs to be adjusted, and the system clock is adjusted to be synchronous with the time of the external RTC based on the time of the external RTC.

S104: the controller identifies hidden danger information in the image to be detected.

Firstly, the controller determines a preset hidden danger comparison list according to the shooting position of an image to be detected.

Different types of hidden dangers may exist for the power transmission lines in different places, and a hidden danger comparison list can be stored in corresponding equipment of the controller in advance. For example, a, the hidden troubles are: x1, x 2; and B, hidden troubles are as follows: x2, x 3.

And then, the controller performs image recognition on the image to be detected through a preset target detection model so as to determine a plurality of object labels in the image to be detected.

The preset target detection model can be a YOLO model or a Faster R-CNN model, and the specific model type is not particularly limited. In the present application, the object tag is, for example: excavators, trees, etc.

And finally, the controller compares the object label with the hidden danger comparison list to determine hidden danger information in the image to be detected. The hidden danger information at least comprises one or more of the following items: construction machinery, trees, buildings.

Taking trees as an example, the trees can be reverse trees which are close to the power transmission line at the corresponding shooting place of the image to be detected, such as reverse trees 5 meters away from the electric wire and the high-voltage line tower. The controller takes the fallen trees as hidden danger information.

In an embodiment of the application, the controller may communicate with the associated device via a wireless communication module, the wireless communication module including one or more of: long-distance wireless roller LoRa, 433m wireless module, 2.4G module.

After the controller sends the synchronous shooting instruction to the associated devices, the associated devices may reply a feedback message to the device generating the synchronous shooting instruction to determine that the feedback controller receives the synchronous shooting instruction. Then, the device corresponding to the controller and the plurality of associated devices may perform shooting, specifically:

the controller determines feedback information for each associated device.

The controller determines synchronous shooting time based on the feedback information, so that the controller shoots corresponding shooting units and a plurality of associated devices of the controller at the synchronous shooting time.

For example, the synchronous shooting time is 5 seconds after the associated device controller sends the synchronous shooting instruction, and after 5 seconds, the device corresponding to the controller and a plurality of associated devices can shoot to obtain hidden trouble images at the same time and at different angles.

For example, at the power transmission line a site, there is a crane, the Q1 monitoring equipment recognizes the crane as hidden danger information, and the Q1 monitoring equipment can generate a synchronous shooting command and send the synchronous shooting command to the Q2, Q3 and Q4 monitoring equipment. Q1, Q2, Q3 and Q4 shoot a plurality of hidden danger images of hidden danger information at different shooting angles simultaneously. According to the method and the device, image splicing processing can be carried out according to the plurality of hidden danger images, and the global image of hidden danger information is obtained.

In addition, the monitoring equipment can be used for acquiring point cloud data, and a point cloud image of panoramic hidden danger information is obtained by splicing a plurality of hidden danger point cloud images acquired by the monitoring equipment at the same time and different shooting angles.

According to the scheme, time synchronization between equipment for monitoring the hidden danger of the power transmission line and time synchronization between the equipment can be achieved, and therefore it is guaranteed that each piece of equipment can shoot the hidden danger image at the same moment. Through the scheme, the situation that the hidden danger images are collected by the monitoring equipment at different moments to cause the abnormal splicing of the hidden danger images or the spliced images do not have hidden danger information can be avoided. The scheme that this application provided can improve transmission line's hidden danger investigation work efficiency, and then guarantee near transmission line personnel life safety and power consumption safety.
