Therefore, how to monitor landslide risk of the strip mine slope and further ensure safe production of the mine is a problem to be solved urgently at present. The strip mine side slope safety monitoring method provided by the embodiment of the application is applied to a server. The server of the present application may be a platform serving an intelligent mining company, and fig. 1 is a first flow schematic diagram of a strip mine slope safety monitoring method provided by an embodiment of the present application, and referring to fig. 1, the method includes the following steps S101 to S105.

S101: and acquiring information that a target sound wave transmitter is in a starting state, wherein the target sound wave transmitter is positioned in a target area.

In the above S101, in the actual open-pit mining plan, as the mining mode and the mining work go deep, there are a plurality of open-pit slopes in one open-pit, and the number and position of each open-pit slope also change, and each open-pit slope is designed according to a certain inclination angle, so it is necessary to monitor the open-pit slope to ensure the safe production of the mine and the life safety of personnel.

When the strip mine side slope is monitored safely, an acoustic wave monitoring system is required to be installed in the existing strip mine side slope of the strip mine to monitor whether safety risk occurs, and before whether the strip mine side slope is monitored, an acoustic wave transmitter is required to be installed on the surface of the strip mine side slope area, and then two acoustic wave receivers are installed at any two different positions in the bottom plane of the strip mine. In the application, a plurality of groups of sound wave monitoring systems are arranged, each group of sound wave monitoring systems comprises a sound wave emitter and two sound wave receivers, and each sound wave emitter is correspondingly arranged with the corresponding two sound wave receivers. In the multiple groups of sound wave monitoring systems, the sound wave frequency emitted by the sound wave emitters of any two groups of sound wave monitoring systems is different, and sound waves with different frequencies cannot interfere with each other or generate cross interference. So that each set of acoustic wave monitoring systems can be operated independently for positioning.

For the strip mine slope, the slope should be three-dimensional, but the strip mine slope can be cut to obtain a plurality of target areas which can be seen as inclined planes, and then a group of sound wave monitoring systems are arranged in each target area. When the target area is monitored by the acoustic wave monitoring system, the target area is approximately planar, so that the positioning can be realized only through two acoustic wave receivers. Particularly, due to the fact that the open side slope is relatively large, the segmented target areas are relatively large, and multiple groups of sound wave monitoring systems are required to be arranged. If each group of acoustic wave monitoring systems adopts three points for positioning, each group of acoustic wave monitoring systems is provided with three or more acoustic wave receivers, which can result in the increase of the overall equipment cost. It is therefore desirable to reduce overall equipment costs by employing the provision of two sonic receivers and performing two-point positioning. Meanwhile, two-point positioning is adopted, the received data volume is greatly reduced, the subsequent calculated volume is also reduced, and the overall monitoring efficiency is improved. The acoustic wave emitter is located in the target area.

Any one of a plurality of acoustic wave monitoring systems is taken as an example for explanation of the target acoustic wave monitoring system. The target sound wave monitoring system comprises a target sound wave transmitter and two sound wave receivers corresponding to the target sound wave transmitter, wherein the first target sound wave receiver and the second target sound wave receiver are used for monitoring the sound wave.

The process of installing sound waves is as follows, a mounting point is selected at a proper position of the side slope, and the stability of the side slope can be better reflected by the selected mounting point. And then installing the target sound wave emitter on the selected installation point, and fixing the target sound wave emitter with the side slope surface to ensure that the target sound wave emitter can work stably. After the target sound wave transmitter is installed in the target area, parameters of the target sound wave transmitter are adjusted, the adjustment comprises the steps of starting the frequency, the amplitude and the waveform of sound waves manually, setting the working mode of the target sound wave transmitter to be automatic, so that the follow-up timing monitoring of the strip mine slope is facilitated, connecting the target sound wave transmitter with the target sound wave receiver, and ensuring that the target sound wave receiver can receive sound wave signals sent by the target sound wave transmitter. In the application, after one target sound wave emitter is arranged on the strip mine side slope, the target sound wave emitter corresponds to two target sound wave receivers, so that whether the current strip mine side slope has landslide or not can be judged according to the monitored data.

In addition, how to acquire the information that the corresponding target sound wave emitter is in the starting state in the target area needs to judge that the target area meets the working condition, and when the target area meets the working condition, a starting instruction can be sent to the target sound wave emitter, so that the target sound wave emitter can be started according to the starting instruction, and the situation that the target sound wave emitter is in the working state for a long time due to the fact that the working condition is not set is avoided, and then the normal operation of the target sound wave emitter is affected. The long-time working state can cause hardware abrasion, the service life of the target sound wave transmitter is influenced, and the target sound wave transmitter needs electric power to support, so that the long-time working state can cause energy consumption to be increased, and the electric power needs to be periodically supplemented and maintained; secondly, the accuracy of the monitoring data is affected when the target sound wave emitter is in the working state for a long time, so that the working time of the target sound wave emitter is reasonably arranged, and the influence on the working operation of the target sound wave emitter is avoided. Whether the target acoustic wave emitter is in an operating state can be judged in two ways. The first determination method is to determine whether safety monitoring is needed currently according to the vibration frequency corresponding to the target area, as shown in fig. 2, and the method includes steps S201-S203.

S201: and acquiring the vibration frequency corresponding to the target area, wherein the vibration frequency is the vibration frequency of the target area acquired by the vibration sensor.

In S201, the target area refers to any one of the strip mine slopes, and several key positions, such as a slope change point, a working step, a rest step, etc., are selected on the strip mine slope as the installation positions of the vibration sensors, and these positions can reflect the overall situation of the slope. After the installation position is selected on the slope of the strip mine, holes are drilled at the selected position, and the vibration sensor is firmly installed in the holes. The sensor is required to be perpendicular to the slope surface to ensure accuracy of measurement. If necessary, cement or other materials can be used for fixing the sensor, so that the sensor is prevented from falling or being moved during operation. And the vibration sensor is connected with the data acquisition unit, the data acquisition unit can receive and record the data of the vibration sensor, and the data can be transmitted to the data acquisition unit in a wired or wireless mode. The server and the data acquisition device transmit in a wireless mode, and the data acquisition device transmits the vibration frequency to the server after acquiring the vibration frequency adopted by the vibration sensor so as to facilitate the judgment of the vibration frequency by the server.

S202: and judging whether the vibration frequency is greater than or equal to a preset vibration threshold value.

In S202, after the server obtains the vibration frequency, it is determined whether the vibration frequency is greater than or equal to a preset vibration threshold, where the preset vibration threshold is a vibration frequency threshold set according to the actual situation of the strip mine slope. The preset vibration threshold value needs to be set by considering a plurality of factors such as characteristics of a side slope, mining modes, climate conditions and the like.

S203: if the vibration frequency is greater than or equal to the preset vibration threshold value, the target area is confirmed to be in a monitoring state, and then the target sound wave emitter in the target area is started so that the target sound wave emitter can execute corresponding operation according to a starting instruction.

In S203, when the vibration frequency is greater than or equal to the preset vibration threshold, it is determined that the slope corresponding to the target area is in an abnormal state, and the strip mine slope needs to be monitored, that is, the server sends a start command to the target acoustic wave emitter, so that the target acoustic wave emitter monitors the strip mine slope according to the start command.

In addition, when the vibration frequency is smaller than a preset vibration threshold value, the slope corresponding to the target area is confirmed to be in a normal state, and a starting instruction is not required to be sent to the target sound wave transmitter, namely, the target sound wave transmitter is not required to be used for carrying out safety monitoring on the strip mine slope.

According to the second mode, whether the target area needs to be safely monitored or not can be judged according to weather information corresponding to the target area. As shown in fig. 3, the method includes steps S301-S303.

S301: and acquiring preset weather information, wherein the preset weather information is weather information of a region corresponding to the target region.

In S301, before the server obtains the preset weather information, when relevant personnel in the open-air mine need to input relevant information of the open-air mine in the server, the area corresponding to the open-air mine needs to be input, so that the corresponding weather information can be obtained according to the area later. After confirming that the area corresponding to the open-pit mine is stored in the server, weather information corresponding to the area at the current time is acquired according to the date displayed on the server.

S302: judging whether the preset weather information is in a preset weather range or not.

In S302, after obtaining the preset weather information, the server sets the weather range according to the actual weather information of the open-air mine, and the weather range is set by summarizing the weather that is easy to be abnormal, where the preset weather range is composed of multiple types of weather, and the preset weather range includes rainy days, rainy and snowy days, and windy days.

S303: if the preset weather information is in the preset weather range, the target area is confirmed to be in the monitoring state, and the target sound wave emitter in the target area is started so that the target sound wave emitter can execute corresponding operation according to the starting instruction.

In S303, when the preset weather information satisfies any one weather information in the preset weather range, it is determined that the preset weather information corresponding to the target area is in an abnormal state, and the safety of the slope corresponding to the target area is required to be monitored, so as to prevent the slope from landslide accidents caused by not timely monitoring the slope.

For example, when the region corresponding to the target area is city a, weather information corresponding to city a is obtained, and if the current weather information is a rainy day, that is, the preset weather information is a rainy day, the preset weather range may be set as a rainy day, a rainy and snowy day, and a windy day; when the preset weather information meets one weather information in a preset weather range, confirming that the target area corresponds to the preset weather information and is in an abnormal state, and sending a starting instruction to the target sound wave emitter corresponding to the target area so that the target sound wave emitter can start to safely monitor the side slope of the target area.

In addition, when the preset weather information does not meet any weather information in the preset weather range, the preset weather information corresponding to the target area is confirmed to be in a normal state, and safety monitoring of the slope corresponding to the target area is not needed temporarily.

S102: obtaining a first time length for the first target sound wave receiver to receive the first sound wave signal, obtaining a first distance, and obtaining a second time length for the second target sound wave receiver to receive the second sound wave signal, obtaining a second distance.

In S102, after determining that the target acoustic wave emitter is in the working state, the target acoustic wave emitter sends acoustic wave signals to the target acoustic wave receivers, where one target acoustic wave emitter corresponds to multiple target acoustic wave receivers, and the multiple target acoustic wave receivers include a first target acoustic wave receiver and a second target acoustic wave receiver, and the target acoustic wave emitter sends acoustic wave signals to the first target acoustic wave receiver and the second target acoustic wave receiver, respectively. The first sound wave signal refers to a sound wave signal sent by the target sound wave transmitter to the first target sound wave receiver, and the second sound wave signal refers to a sound wave signal sent by the target sound wave transmitter to the second target sound wave receiver.

And then respectively calculating the distance between the first target sound wave receiver and the target sound wave transmitter, namely the first distance. After the first target sound wave receiver receives the first sound wave signal sent by the target sound wave transmitter, acquiring a first duration, when the target sound wave transmitter sends the first sound wave signal to the first target sound wave receiver, the first sound wave signal carries a time point when the target sound wave transmitter sends the first sound wave signal to the first target sound wave receiver, acquiring a time point when the first sound wave signal is received from the first target sound wave receiver, calculating a difference value between the time point when the first sound wave signal is received and the sending time point, wherein the difference value is the first duration, and the first duration represents a duration corresponding to the time when the first target sound wave receiver receives the first sound wave signal. The transmission speed of the first sound wave signal sent by the target sound wave transmitter is acquired, namely, the first speed. And multiplying the first time length by the first speed to obtain a first distance, wherein the first distance is the distance between the current target sound wave transmitter and the first target sound wave receiver.

And then calculating the distance between the second target sound wave receiver and the target sound wave transmitter, namely, the second distance. After the first target sound wave receiver receives the second sound wave signal sent by the target sound wave transmitter, acquiring a second duration, when the target sound wave transmitter sends the second sound wave signal to the second target sound wave receiver, the target sound wave transmitter is carried in the second sound wave signal to send a time point to the second target sound wave receiver, acquiring the time point of receiving the second sound wave signal from the second target sound wave receiver, calculating a difference value between the time point of receiving the second sound wave signal and the sending time point, wherein the difference value is the second duration, and the second duration represents the duration corresponding to the second target sound wave signal received by the second target sound wave receiver. The transmission speed of the second sound wave signal transmitted by the target sound wave transmitter is acquired, namely, the second speed. And multiplying the second time length by the second speed to obtain a second distance, wherein the second distance is the distance between the current target sound wave emitter and the second target sound wave receiver.

S103: the target position is determined based on the first distance and the second distance.

In S103, after obtaining the first distance and the second distance, the server may construct a two-dimensional plane according to the slope of the slope corresponding to the target area, and determine coordinates of known points in the two-dimensional plane, where the coordinates of the known points are coordinates corresponding to the first target acoustic wave receiver and the second target acoustic wave receiver. And marking the first target acoustic wave receiver and the second target acoustic wave receiver in a two-dimensional plane, the target position can be calculated by constructing a circle. The coordinates of the target point are calculated according to the first distance and the coordinates of the known point, and a preset first circle is obtained by taking the coordinates of the first target sound wave receiver as the circle center and taking the first distance as the radius. And then taking the coordinates of the second target sound wave receiver as the circle center and taking the second distance as the radius to obtain a preset second circle, and determining the intersecting position between the preset first circle and the preset second circle in the two-dimensional plane, wherein the intersecting position is a preset point of the application, and the preset point is a target position. The method comprises the steps of obtaining a first position corresponding to a first sound wave receiver, wherein a point A shown in fig. 4 is used as a starting point, the point A represents coordinates of the first sound wave receiver, drawing a straight line with a radius of a first distance, namely a first straight line, and drawing a preset first circle by taking the point A as a circle center according to the first straight line as the radius. And obtaining a second position corresponding to the second acoustic receiver, wherein a point B shown in fig. 4 is used as a starting point, the point B represents coordinates of the second acoustic receiver, a straight line with a radius of a second distance is drawn, namely a second straight line, and a preset second circle is drawn according to the second straight line as a radius and the point B is used as a circle center. And acquiring a point at which the first straight line and the second straight line intersect, namely presetting a point at which the first circle and the second circle intersect as preset points in fig. 4, wherein the preset points represent target positions. Point C in fig. 4 is the target position. When the sound wave transmitter transmits the sound wave signal to the sound wave receiver, the sound wave receiver can determine the direction of the sound wave receiver for transmitting the sound wave signal, so that the direction corresponding to the target position can be determined according to the direction of the sound wave transmitter for transmitting the sound wave signal.

S104: and judging whether the target position is in a preset position range.

In S104, after determining the target position, the server determines whether the target position is within the preset position range, including: calculating a position difference value between the target position and a preset position when the target position is acquired; and judging whether the position difference value is in a preset position range or not. The preset position refers to a corresponding position of the target acoustic wave emitter initially installed in the target area, and the target position and the preset position can be represented by numerical values. And then calculating a difference value between the target position and the preset position, namely a position difference value. The position difference value is the position difference value between the target position and the preset position after the target sound wave transmitter transmits sound wave signals to the first target sound wave receiver and the second target sound wave receiver; the position difference is a difference obtained by comparing the target position with the initially installed position according to the target position obtained after the target sound wave transmitter transmits sound wave signals to the first target sound wave receiver and the second target sound wave receiver, and the position difference obtained in different time periods is different based on the target position.

After the position difference is obtained, whether the position difference is within a preset position range is judged, and the preset position range refers to a position range set by the fact that the target sound wave emitter can normally move when the target sound wave emitter is initially installed in the target area. I.e., the preset position range, can also be understood as the normal position difference between the distance the target sonic transmitter can normally move to the initial installation position in the present application. And judging whether the target position is in a preset position range or not through the coordinates, acquiring the corresponding coordinates of the target position in the two-dimensional platform, namely, the target coordinates, wherein the preset position range represents the coordinates, namely, the preset positions, corresponding to the initial installation of the target acoustic transmitter in the target area, and judging whether the target coordinates are equal to the preset coordinates or not.

In addition, in further discussion of determining the target position by using the first target sound wave receiver and the second target sound wave receiver, the application scene of the application is to monitor the landslide of the strip mine slope, and because the strip mine slope has a certain inclination, when one target sound wave receiver is arranged at any position in the bottom plane of the strip mine after the target sound wave transmitter is arranged on the surface of the strip mine slope, namely the target sound wave receiver is arranged at the ground position of the mine. And drawing a preset circle by taking the distance between the target sound wave receiver and the target sound wave transmitter as a circle center and taking the distance between the target sound wave receiver and the target sound wave transmitter as a radius, wherein each point on the preset circle can represent the position of the target sound wave transmitter, namely a plurality of target positions corresponding to the target sound wave transmitter exist. When the distance from the target sound wave receiver to the target sound wave transmitter is used for determining the target position, the distance from the target sound wave receiver to the target sound wave transmitter cannot be determined when the target sound wave receiver is damaged or fails, and therefore the target position cannot be determined.

When two target sound wave receivers are arranged at the plane positions corresponding to the strip mine slopes, the first distance between the target sound wave transmitter and the first target sound wave receiver is respectively obtained, the second distance between the target sound wave transmitter and the second target sound wave receiver is obtained, and the target positions, namely two-point positioning, can be determined through the first distance and the second distance, as shown in fig. 4. The target positions determined by the two target sound wave receivers are more accurate than the target positions determined by the single target sound wave receiver, a plurality of target positions are determined by the single target sound wave receiver, and only one target position is determined by the two target sound wave receivers.

S105: if the target position is not in the preset position range, confirming that the corresponding strip mine slope in the target area is in an abnormal state, and processing the corresponding strip mine slope in the target area according to the abnormal state.

In S105, when the target position is not within the preset position range, the coordinates corresponding to the target position have moved in the two-dimensional plane, and it is determined that the corresponding strip mine slope in the current target area is in an abnormal state, that is, the abnormal state indicates that a landslide accident may occur on the strip mine slope, and abnormal information needs to be sent to the user equipment, so that related personnel can check the corresponding strip mine slope in the target area according to the abnormal information, and safety accidents are prevented.

In a possible implementation manner, when the target position is within the preset position range, the coordinates corresponding to the target position do not move in the two-dimensional plane, and it is confirmed that the corresponding strip mine slope in the current target area is in a normal state, and abnormal information is not needed to be sent to the user equipment temporarily. When the corresponding strip mine slope in the target area is confirmed to be in a normal state, in order to prevent errors of single monitoring data, the third sound wave signal sent by the target sound wave transmitter is received again, and at the moment, the third sound wave signal is a signal after the first sound wave signal and the second sound wave signal. After obtaining two distances corresponding to the third sound wave signal, determining a target position according to the two distances, judging whether the target position is still in a preset position range, and sending a stop working instruction to the target sound wave emitter by the server when the target position is still in the preset position range so as to facilitate the target sound wave emitter to execute corresponding operation according to the stop working instruction.

In a possible implementation manner, when it is determined that the target position is not within the preset position range, the target acoustic transmitter and the target acoustic receiver in each target area are respectively provided with a shooting device, and the shooting devices can be cameras or the like, so that when shooting videos corresponding to the respective target areas are acquired later, the corresponding shooting devices in each target area can be numbered, and the corresponding shooting videos can be acquired later according to the numbers of the shooting devices. The method comprises the steps that the corresponding shooting equipment numbers in a target area can be obtained, and then a preset video is called according to the shooting equipment numbers, wherein the preset video is a video of the target area shot by a camera corresponding to the shooting equipment numbers; after the preset video is uploaded to the server, the server can analyze the preset video conveniently, pictures corresponding to the preset video are displayed to a user, the user can judge the abnormal state of the slope conveniently according to the preset video, and corresponding treatment measures are taken according to the level of the abnormal state. The landslide condition may be specifically classified into several abnormal grades, and may be set based on actual conditions, which are not limited herein.
