Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
Taking the hoisting equipment as an example, due to the fact that the working sites are relatively dispersed in the use scene, a considerable part of the working sites are distributed in the field areas far away from cities, the change of the wind speed in the field is obvious, and the crane arm support and other structures can be abnormally swung when the change is large, so that potential safety hazards are caused to the hoisting equipment.
In the prior art, the wind speed value at the working position of the working machine is mostly predicted through the wind speed value in weather forecast, but the wind speed value is influenced by terrain, buildings, ground water systems and the like, so that the wind speed value cannot be accurately predicted, and the problem that high-precision wind speed early warning cannot be performed is caused.
Therefore, the invention provides a wind speed early warning method. Fig. 1 is a schematic flow chart of a wind speed early warning method provided by the present invention, and as shown in fig. 1, the method includes the following steps:
and step 110, determining an initial observation point, and setting the unmanned aerial vehicle for measuring the wind speed based on the initial observation point.
Here, the initial observation point refers to an observation point that is a certain distance from the working position of the working machine, and the wind speed measured at the initial observation point can predict the wind speed at the working position after a certain time. It should be noted that, if the wind speed is directly measured at the operation position in real time, when the wind speed is greater than the early warning threshold, the operator does not have enough time to perform corresponding processing, and further, the abnormal swing of the operation component of the operation machine may be caused by the excessive wind speed, which may cause a potential safety hazard. For example, when the wind speed is too high, the structure such as the arm support of the crane can swing abnormally, and further potential safety hazards are brought to the crane. If the wind speed is measured at the initial observation point, and the wind speed of the operation position after a period of time is predicted based on the wind speed measured at the initial observation point, so that the operation personnel have enough time to perform corresponding processing, and the potential safety hazard brought to the operation machine by the overlarge wind speed at the operation position is avoided.
The method and the device can identify the terrain around the operation position based on the 3D map, and determine the initial observation point by combining the forecast condition of the wind speed of the day. The distance between the initial observation point and the work machine is generally the product of the reaction time of the operator plus the evasive maneuver completion time and the wind speed exceeding the warning threshold. And if the wind speed is the early warning wind speed, the sum of the early warning wind speed multiplied by the operator reaction time and the action evasion completion time is used.
In addition, the determination of the initial observation point requires consideration of the wind direction. For example, for a crane with a long boom, the influence of the same wind in different directions on the crane is different. The initial observation point is set on the basis of the current-day wind condition forecast (including wind speed and wind direction), and if the crane can be determined to be downstream of the wind according to the current-day wind condition forecast, the initial observation point can be set according to the wind direction.
After the initial observation point is determined, the wind speed measuring instrument can be installed on the unmanned aerial vehicle, and the unmanned aerial vehicle is released to the initial observation point, so that the wind speed measuring instrument on the unmanned aerial vehicle can measure the initial wind speed value of the initial observation point in real time.
In addition, because the wind speeds corresponding to different heights at the same position are different, and the boom of the working machine usually works at high altitude, in order to accurately predict the wind speed of the boom when the working machine works at high altitude, the height of the initial observation point needs to be consistent with the height of the boom, and the wind speed of the boom can be accurately predicted.
It can be understood that, in order to accurately obtain the initial wind speed value, a plurality of unmanned aerial vehicles can be set at the initial observation point according to the preset distribution angle, so as to obtain the initial wind speed value of the initial observation point through a plurality of unmanned aerial vehicles.
and step 130, when the predicted wind speed value is larger than the early warning threshold value, early warning the wind speed.
Specifically, the measured wind speed value refers to a real-time wind speed value measured by the unmanned aerial vehicle, and if the unmanned aerial vehicle is set at the initial observation point, the corresponding measured wind speed value is the initial wind speed value measured by the initial observation point; and if the unmanned aerial vehicle is arranged at a relay observation point between the initial observation point and the target observation point, the corresponding measured wind speed value is a relay wind speed value measured by the relay observation point. The predicted wind speed value refers to the wind speed value that the target observation point can reach after a period of time.
Since the unmanned aerial vehicle is usually arranged in the high altitude, and there are few obstacles in the high altitude, that is, the attenuation of the wind speed from the initial observation point to the working position is negligible in an ideal situation, that is, when the initial wind speed value is measured at the initial observation point, the predicted wind speed value at the working position is equal to the initial wind speed value after a period of time. If the wind speed decays from the initial observation point to the working position, the decay rate of the initial wind speed value can be determined according to the distance between the initial observation point and the working position, for example, the initial wind speed value is 10m/s, the decay rate is 1m/s per 100m, and the distance between the initial observation point and the target observation point is 500m, and then the predicted wind speed value of the target observation point is 5 m/s.
Optionally, under the condition that the initial wind speed value is not attenuated, when the initial wind speed value is greater than the early warning wind speed value, the wind speed value at the operation position after a period of time reaches the initial wind speed value, that is, the predicted wind speed value at the operation position after a period of time is greater than the early warning wind speed value, so that the operation machine has a potential safety operation hazard after a period of time, and at the moment, wind speed early warning can be performed to prompt an operator. For example, the wind speed abnormality can be displayed through the display screen, a warning sound with certain intensity is emitted through the warning lamp and flickers, and an operator is reminded of carrying out corresponding treatment and decision.
Optionally, under the condition that the initial wind speed value is attenuated, a predicted wind speed value of the target observation point can be determined based on the initial wind speed value and the wind speed change rate, when the predicted wind speed value is larger than the early-warning wind speed value, it is indicated that safety operation hidden dangers exist in the operation machine after a period of time, and at the moment, wind speed early warning can be performed to prompt an operator.
In addition, the measured wind speed value is automatically acquired by the unmanned aerial vehicle, the predicted wind speed value at the operation position can be determined based on the measured wind speed value, and further, when the predicted wind speed value is larger than the early warning threshold value, the wind speed early warning can be automatically and quickly carried out, compared with the traditional method that a wind speed measuring instrument is manually held for wind speed measurement, the manpower loss is greatly reduced; meanwhile, the manual measurement in the traditional method can not realize the high-altitude measurement of the unmanned aerial vehicle, and the measured wind speed value obtained by the measurement of the unmanned aerial vehicle can be subjected to data sharing, for example, the unmanned aerial vehicle can send the measured wind speed value to other unmanned aerial vehicles, so that the problem that resources are consumed due to the fact that other unmanned aerial vehicles repeatedly acquire the measured wind speed value is solved.
It should be noted that, the wind speed early warning performed in the embodiment of the present invention is performed only when the wind speed has a large influence on the working condition of the current operating machine (e.g., a crane), and if the crane is in a short main arm working condition, the wind speed early warning is not required.
According to the wind speed early warning method provided by the embodiment of the invention, the predicted wind speed value of the target observation point can be obtained based on the measured wind speed value obtained by measurement of the unmanned aerial vehicle, and wind speed early warning is carried out when the predicted wind speed value is greater than the early warning threshold value, so that an operator can have enough time to carry out corresponding processing, the problem that potential safety hazards are brought to the operation machine due to overlarge wind speed at an operation position is avoided, and the safe and stable operation of the operation machine is ensured.
Based on the above embodiment, set up the unmanned aerial vehicle that is used for wind speed measurement based on initial observation point, include:
and determining a relay observation point based on the initial observation point and the target observation point, and setting the unmanned aerial vehicle at the initial observation point and the relay observation point.
Specifically, since a certain distance exists between the initial observation point and the target observation point, the initial wind speed value attenuates from the initial observation point to the target observation point, and in order to further accurately obtain the predicted wind speed value, in the embodiment of the present invention, one or more relay observation points may be set between the initial observation point and the target observation point, and the unmanned aerial vehicles may be set at the initial observation point and each relay observation point to obtain the measured wind speed value.
In addition, the relay observation point arranged between the initial observation point and the target observation point can be regarded as a network relay signal station, so that the wind speed values measured by the initial observation point and the relay observation point can be guaranteed to be sent to the server under the condition of poor network quality, and the server can determine the predicted wind speed value of the target observation point according to the wind speed values measured by the initial observation point and the relay observation point. It can be appreciated that the server may be disposed on the work machine such that the server may prompt for an early warning in time when determining that the predicted wind speed value is greater than the early warning threshold value. The server can also be arranged at a remote server, and when the remote server determines that the predicted wind speed value is greater than the early warning threshold value, the server can send early warning prompts to operating personnel of the operating machine in time, so that the operating personnel can process the wind speed value in time, and the safety of the operating machine is guaranteed.
Based on any embodiment, the measured wind speed value comprises an initial wind speed value measured by an initial observation point and a relay wind speed value measured by a relay observation point;
determining a predicted wind speed value of a target observation point based on a measured wind speed value measured by an unmanned aerial vehicle; the target observation point is a working position of the working machine, and includes:
determining a wind speed change rate based on the relay wind speed value, the initial wind speed value, the relay observation point and the initial observation point;
and determining a predicted wind speed value based on the wind speed change rate, the initial wind speed value, the initial observation point and the target observation point.
Specifically, the unmanned aerial vehicle is arranged at an initial observation point and a relay observation point, so that a measured wind speed value obtained by measurement of the unmanned aerial vehicle at the initial observation point is an initial wind speed value and is used for representing real-time wind speed information of the initial observation point; and the measured wind speed value obtained by the unmanned aerial vehicle at the relay observation point is the relay wind speed value and is used for representing the real-time wind speed information of the relay observation point.
After the relay wind speed value and the initial wind speed value are obtained, a wind speed difference value between the initial wind speed value and the relay wind speed value can be determined, and a distance difference value between the initial observation point and the relay observation point can be determined based on the initial wind speed value and the relay observation point, so that a wind speed change rate can be determined based on the wind speed difference value and the distance difference value, and the wind speed change rate is used for representing attenuation information of wind speed.
Further, based on the target observation point and the initial observation point, a distance difference between the target observation point and the initial observation point can be determined, and the wind speed change rate can be used for representing attenuation information of the wind speed, so that the attenuation from the initial wind speed value of the initial observation point to the target observation point can be obtained, and the predicted wind speed value can be obtained.
Therefore, the predicted wind speed value determined based on the relay wind speed value, the initial wind speed value, the relay observation point and the initial observation point in the embodiment of the invention takes the attenuation of the wind speed into consideration, so that the precision of the predicted wind speed value is further improved, and the operation safety of the operation machine can be further ensured.
Based on any of the above embodiments, determining a wind speed change rate based on the relay wind speed value, the initial wind speed value, the relay observation point, and the initial observation point includes:
calculating a difference value between the initial wind speed value and the relay wind speed value to obtain a wind speed difference value;
determining a distance difference value based on the initial observation point and the relay observation point;
and determining the wind speed change rate based on the wind speed difference value and the distance difference value.
Specifically, a measured wind speed value obtained by measurement of the unmanned aerial vehicle at the initial observation point is an initial wind speed value and is used for representing real-time wind speed information of the initial observation point; and the measured wind speed value obtained by the unmanned aerial vehicle at the relay observation point is the relay wind speed value and is used for representing the real-time wind speed information of the relay observation point. After the relay wind speed value and the initial wind speed value are obtained, a wind speed difference value between the initial wind speed value and the relay wind speed value can be determined, and a distance difference value between the initial observation point and the relay observation point can be determined based on the initial wind speed value and the relay observation point, so that a wind speed change rate can be determined based on the wind speed difference value and the distance difference value, and the wind speed change rate is used for representing attenuation information of wind speed.
Based on any embodiment above, after setting the unmanned aerial vehicle for wind speed measurement based on the initial observation point, the method further includes:
when the operation height is larger than the height threshold value, the distance between the unmanned aerial vehicle and the target observation point is increased;
and when the operation height is less than or equal to the height threshold value, the distance between the unmanned aerial vehicle and the target observation point is reduced.
Specifically, in the process of operating by the operating machine, the height of the operating machine is constantly changed, and the wind speeds corresponding to different heights are different, so that if the operating height is increased, the height of the unmanned aerial vehicle can be correspondingly increased to a position consistent with the operating height; if the operation height is reduced, the height of the unmanned aerial vehicle can be correspondingly reduced to the position consistent with the operation height, and therefore the predicted wind speed value can be accurately obtained.
When the operation height is greater than the height threshold value, it indicates that the height between the target observation point and the unmanned aerial vehicle is also greater than the height threshold value, and as the height is higher, the obstacles between the target observation point and the unmanned aerial vehicle are fewer, namely the attenuation of the wind speed is smaller, and the distance between the unmanned aerial vehicle and the target observation point can be increased, so that the number of the unmanned aerial vehicles can be reduced, and the measurement cost is saved. When the operation height is smaller than or equal to the height threshold value, the height between the target observation point and the unmanned aerial vehicle is smaller than or equal to the height threshold value, and due to the reduction of the height, obstacles between the target observation point and the unmanned aerial vehicle are increased, so that the attenuation of the wind speed is increased, the distance between the unmanned aerial vehicle and the target observation point can be reduced, the number of the unmanned aerial vehicles is increased, and the predicted wind speed value is accurately obtained.
Based on any embodiment above, after setting the unmanned aerial vehicle for wind speed measurement based on the initial observation point, the method further includes:
when the measured wind speed value is larger than the wind speed threshold value, the distance between the unmanned aerial vehicle and the target observation point is increased;
and when the measured wind speed value is less than or equal to the wind speed threshold value, the distance between the unmanned aerial vehicle and the target observation point is reduced.
Specifically, in the process of the operation machine, the measured wind speed value may be constantly changed, and when the measured wind speed value is greater than the wind speed threshold value, in order to reserve sufficient early warning response time for the operator, the distance between the unmanned aerial vehicle and the target observation point needs to be increased. When the measured wind speed value is smaller than or equal to the wind speed threshold value, the early warning response time of the operating personnel is enough, and at the moment, in order to ensure the accuracy of obtaining the predicted wind speed value, the distance between the unmanned aerial vehicle and the target observation point can be reduced.
Based on any of the above embodiments, the present invention further provides a wind speed early warning method, which is described below by taking wind speed early warning during operation of a crane as an example, as shown in fig. 2, and the method includes:

In addition, the unmanned aerial vehicle can be released in multiple directions and is not limited to front, back, left and right.
