Description

Technical Field

[0001] This invention relates to the field of crane technology, and more specifically to a wind speed warning method, device, and system for operating machinery. Background Technology

[0002] Wheeled cranes are susceptible to wind speed fluctuations during operation. When operating for extended periods, operators often need to disconnect the power to the equipment during periods of static operation. Therefore, existing technologies typically equip cranes with anemometers for wind speed monitoring. However, if strong winds occur while the operator is away, it may be too late to retract the crane by the time the anemometer detects the alarm wind speed, potentially leading to damage from the strong winds. Summary of the Invention

[0003] This invention provides a wind speed warning method, device, and system for operating machinery to solve the problem of untimely wind speed warnings.

[0004] In a first aspect, the present invention provides a wind speed warning method for operating machinery, wherein the operating machinery is equipped with a wind speed detection device, and the method includes: acquiring a first wind speed from a weather station and a second wind speed at the current moment detected by the wind speed detection device; predicting a third wind speed after a preset time interval based on the second wind speed, wherein the preset time interval is determined in advance based on the operating machinery's closing time; comparing the first wind speed with the third wind speed to determine the maximum wind speed, and issuing a wind speed warning based on the maximum wind speed.

[0005] The wind speed warning method for operating machinery provided by this invention predicts a third wind speed after a preset time interval based on the second wind speed detected by a wind speed detection device at the current moment, compares the first wind speed obtained from the meteorological station with the predicted third wind speed, and issues a wind speed warning based on the maximum wind speed. This method comprehensively considers the wind speed changes at the location of the operating machinery and the wind speed monitored by the meteorological station, thereby issuing a warning based on the maximum wind speed. This allows sufficient time for the operating machinery to be brought down, avoids damage to the operating machinery and other equipment when strong winds arrive, and ensures the safety of operators.

[0006] In one optional implementation, predicting a third wind speed after a preset time interval based on a second wind speed includes: acquiring a fourth wind speed detected by a wind speed detection device at the previous moment; calculating the wind speed difference between the second and fourth wind speeds, and integrating the wind speed difference based on the preset time interval to obtain the third wind speed.

[0007] This invention predicts the wind speed after a preset time interval based on the wind speed changes at the location of the operating machinery. It can dynamically monitor the wind force value after the preset time interval in real time, so as to respond more quickly to the instantaneous changes in wind speed and improve the vehicle's adaptability in complex wind environments. Moreover, wind speed prediction based on integral calculation has the advantages of low cost and easy implementation, and is suitable for the operating scenarios of operating machinery.

[0008] In one optional implementation, a first wind speed is compared with a third wind speed to determine the maximum wind speed, and a wind speed warning is issued based on the maximum wind speed. This includes: if the first wind speed is the maximum wind speed, obtaining first location information of the weather station and second location information of the operating machinery; determining the horizontal distance between the weather station and the operating machinery based on the first and second location information; calculating the expected time interval for the wind to reach the operating machinery from the weather station based on the horizontal distance and the first wind speed; comparing the expected time interval with a preset time interval, and if the expected time interval is less than the preset time interval, issuing a wind speed warning based on the first wind speed.

[0009] This invention calculates the estimated time interval between the wind speed at the location of the weather station and the location of the operating machinery. Based on the estimated time interval and the preset time interval required for the machinery to be brought down, it can determine whether a wind speed warning is needed. This is to avoid damage to equipment or injury to personnel caused by insufficient time to bring down the machinery when strong winds from a distance reach it.

[0010] In one optional implementation, the first wind speed is compared with the third wind speed to determine the maximum wind speed, and a wind speed warning is issued based on the maximum wind speed, including: if the third wind speed is the maximum wind speed, then a wind speed warning is issued based on the third wind speed.

[0011] This invention predicts that the wind speed at the location of the operating machinery will reach a relatively high level after a preset time interval required for the machinery to be withdrawn, and promptly issues an alarm, thereby reserving sufficient time for the machinery to be withdrawn.

[0012] In one alternative implementation, wind speed warning based on maximum wind speed includes: comparing the maximum wind speed with a safe wind speed threshold, and determining the warning level based on the comparison result, so as to issue a warning based on the warning level.

[0013] This invention provides operators with different warning instructions by determining the warning level corresponding to the wind speed. Based on the warning instructions, operators can adjust the vehicle retrieval speed to complete the retrieval before the strong winds arrive, thus ensuring the safety of equipment and personnel.

[0014] Secondly, the present invention provides a wind speed warning device for operating machinery. The operating machinery is equipped with wind speed detection equipment.

[0015] Thirdly, the present invention provides a wind speed warning system for operating machinery, comprising: a wind speed warning platform and a wind speed detection device, wherein the wind speed detection device is fixed to the operating machinery and connected to the wind speed warning platform; the wind speed warning platform comprises: a memory and a processor, wherein the memory and the processor are interconnected, the memory stores computer instructions, and the processor executes the computer instructions to perform the wind speed warning method for operating machinery described in the first aspect or any corresponding embodiment.

[0016] This invention deploys a wind speed warning system for operating machinery, which comprehensively considers the wind speed changes at the location of the machinery and the wind speed monitored by the weather station. It then issues warnings based on the maximum wind speed, allowing sufficient time for the machinery to be brought to a stop, thus preventing damage to the machinery and equipment during strong winds and ensuring the safety of operators.

[0017] In one optional embodiment, the wind speed detection device includes: a wind cup, a wind speed detection device body, and a power module; the power module includes: an external power supply interface and an internal energy storage battery, and the internal energy storage battery serves as the weight of the wind speed detection device body.

[0018] This invention provides two power supply methods for the wind speed detection device. After the operator disconnects the power to the device during static operation, it can be powered by the internal energy storage battery. This allows the wind speed detection device to continue data acquisition and storage even after the external power supply is interrupted, thereby ensuring real-time monitoring of wind speed changes.

[0019] In one alternative implementation, the system further includes a handheld wind speed monitoring terminal, and the wind speed early warning platform is connected to the handheld wind speed monitoring terminal and the operating machinery.

[0020] In one optional embodiment, the wind speed detection device further includes a communication module, which includes a wired communication module and a wireless communication module. The wind speed detection device is connected to the wind speed early warning platform through the wired communication module and to the wind speed early warning platform and a handheld wind speed monitoring terminal through the wireless communication module.

[0021] This invention deploys a handheld wind speed monitoring terminal and a wireless communication module for the wind speed detection equipment, enabling operators to receive real-time wind speed warnings even when work is paused. This allows them to stop the vehicle in time before strong winds arrive, ensuring the safety of equipment and personnel.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] As an optional application scenario of this invention, such as Figure 1 As shown, the wind speed warning system 1 of the operating machinery includes: a wind speed warning platform 10, a wind speed detection device 11, and a handheld wind speed monitoring terminal 12. The wind speed detection device 11 is fixed to the operating machinery 2 and connected to the wind speed warning platform 10. The wind speed warning platform 10 is connected to the handheld wind speed monitoring terminal 12 and the operating machinery 2. At the same time, the wind speed warning platform 10 can communicate with the weather station 3 to obtain the meteorological information monitored by the weather station 3.

[0030] Furthermore, the wind speed detection device 11 includes: a wind cup 111, a wind speed detection device body 112, and a power module 113. The power module 113 includes: an external power supply interface 1131 and an internal energy storage battery 1132, and the internal energy storage battery 1132 serves as a counterweight for the wind speed detection device body 112. Figure 2 As shown. When the operating machinery 2 is powered on, it supplies power to the wind speed detection device 112 via the external power supply interface 1131, and simultaneously charges the internal energy storage battery 1132. The wind speed detection device 11 can detect the wind speed at the location of the operating machinery 2 in real time. When the operating machinery 2 is powered off, the wind speed detection device 11 cannot detect the external power source, and the internal energy storage battery 1132 supplies power to the wind speed detection device 112 to ensure that the wind speed detection device 11 can continuously detect the wind speed at the location of the operating machinery 2.

[0031] In addition, the wind speed detection device 11 also includes a communication module 114, which includes a wired communication module 1141 and a wireless communication module 1142. The wind speed detection device 11 is connected to the wind speed warning platform 10 via the wired communication module 1141 (e.g., a cable) to achieve wired communication. The wind speed detection device 11 can also be connected to the wind speed warning platform 10 and the handheld wind speed monitoring terminal 12 via the wireless communication module 1142 (e.g., a wireless transmitter), or wirelessly connected via the operating machinery 2, which in turn wirelessly connects to the wind speed warning platform 10 to achieve wireless communication.

[0032] Taking a wheeled crane as an example, the retraction process of a wheeled crane is a crucial operation for restoring the equipment from its operational state to its driving state after work is completed. Strict adherence to operating procedures is essential to ensure safe and stable reset of the equipment and prevent structural damage or accidents due to improper operation. The retraction process of a wheeled crane includes: releasing the hook load, retrieving the wire rope and hook, operating the boom in the order of luffing followed by extension, retracting the outriggers in the order of retracting the vertical outriggers followed by the horizontal outriggers, resetting the slewing mechanism, and completing the final retraction operation. It is evident that retraction requires a certain amount of time. Especially when the equipment has been operating for extended periods, the operator will disconnect the power to the equipment during static operation. If wind speed warnings cannot be issued in time when strong winds arrive, insufficient retraction time will result, potentially causing equipment damage or personnel injury. This invention provides a wind speed warning method for operating machinery. By comprehensively considering wind speed changes at the location of the operating machinery and wind speeds monitored by weather stations, timely wind speed warnings are issued to allow sufficient retraction time for the operating machinery.

[0033] According to an embodiment of the present invention, a wind speed warning method for operating machinery is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0034] This embodiment provides a wind speed warning method for operating machinery, which can be used in the aforementioned wind speed warning platform. Figure 3 This is a flowchart of a wind speed warning method for operating machinery according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps: Step S301: Obtain the first wind speed of the weather station and the second wind speed detected by the wind speed detection device at the current moment.

[0035] Specifically, in this embodiment of the invention, a wheeled crane is used as an example of the operating machinery. Regardless of whether the wheeled crane is powered off, the wind speed detection equipment can continuously detect the wind speed information at the location of the wheeled crane. A meteorological station is a specialized facility used to continuously monitor, record, and transmit atmospheric physical and meteorological elements. Its core function is to provide accurate data support for weather forecasting, climate analysis, and disaster prevention and mitigation, and to monitor key meteorological elements in real time, including temperature, air pressure, humidity, precipitation, wind speed, wind direction, sunshine duration, and visibility. Therefore, in order to issue wind speed warnings, the wind speed warning platform maintains communication with the meteorological station and the wind speed detection equipment to obtain the first wind speed detected by the meteorological station at the current moment. The second wind speed obtained by the wind speed detection equipment .

[0036] Step S302: Predict the third wind speed after a preset time interval based on the second wind speed. The preset time interval is determined in advance based on the operating machinery's return time.

[0037] Specifically, in this embodiment of the invention, the weather station is generally deployed in an open area to avoid obstruction and interference, and therefore is usually at a certain distance from the working position of the wheeled crane. Therefore, the first wind speed detected... Compared to wheeled cranes, wind speed detection has a time lag, therefore it can be directly used as a benchmark for wind speed warnings. Wind speed detection equipment is fixed to the wheeled crane, such as at the top of the boom or above the cab, in locations higher than the highest point of the equipment and without structural obstructions. Real-time data collection of the current wind speed at the work point directly reflects the instantaneous wind conditions of the suspended load and the boom, providing highly timely data. Therefore, if a second wind speed is to be detected by the wind speed detection equipment... To issue a wind speed warning, the second wind speed needs to be increased. The lag.

[0038] Furthermore, in order to allow sufficient time for the operation of the machinery to be withdrawn, a preset time interval is set in advance according to the withdrawal time. And preset time interval Preferably, the preset time interval should be longer than the operating machinery's return time, and the longer the operating machinery's return time, the longer the preset time interval should be. The larger the interval, the better. For example, if the downtime of the operating machinery needs to be 1 hour, the preset time interval can be increased. The settings of 1.5 hours or 2 hours are merely examples and not limitations. This allows the wind speed warning platform to determine the most timely second wind speed. Predict the third wind speed after a preset time interval That is, to increase the second wind speed The lag, with the third wind speed As a basis for wind speed warnings.

[0039] Step S303: Compare the first wind speed with the third wind speed to determine the maximum wind speed, and issue a wind speed warning based on the maximum wind speed.

[0040] Specifically, in this embodiment of the invention, the first wind speed The third wind speed represents the large-scale, macroscopic wind field conditions surrounding the work area. This represents a small-scale, microscopic change in wind speed within the operational area, specifically the first wind speed recorded at the weather station. With the predicted third wind speed Compare the two and take the maximum wind speed. As a basis for wind speed warning decisions. Among them, if This indicates that the intensity of the wind field over a large area is already higher than the current and short-term forecast values ​​at the work site, which may indicate that the wind speed at the work site will increase as the macro-wind field strengthens (such as when the outer circulation of the typhoon approaches). Therefore, it is necessary to... Early warning based on baseline; if This indicates that due to local terrain (such as wind around buildings, valley gusts) or instantaneous wind changes, the wind speed at the work site will exceed the intensity of the macroscopic wind field in the short term (such as sudden gusts), requiring [further action]. This serves as the baseline for emergency response. In this embodiment of the invention, the maximum value of both values ​​is used to cover the combined risks of two scenarios, such as a stable macro-wind field but a rapid increase in wind speed at the work site, avoiding missed detections based on a single data point. If the maximum wind speed... If the wind speed is below the safe wind speed threshold, a message will be displayed indicating that the current wind speed is safe and normal operation is permitted. The primary wind speed will be continuously updated. Second style And continuously predict the third wind speed after a preset time interval. To dynamically refresh the maximum wind speed If the maximum wind speed If the wind speed exceeds the safe wind speed threshold, a wind speed warning will be issued through sound and light, notification, or other means to remind the operator to stop the vehicle in time.

[0041] In some optional implementations, embodiments of the present invention can pre-set safe wind speed thresholds corresponding to multiple warning levels, and set the first wind speed... and the third wind speed Maximum wind speed By comparing wind speeds with various safe wind speed thresholds to determine the warning level, a corresponding wind speed warning is issued based on the warning level. For example, a low-level wind speed warning is a notification warning, while a high-level wind speed warning is an audible and visual alarm. This is just an example and not a limitation. By determining the warning level corresponding to the wind speed, this invention can provide operators with different warning instructions. Based on the warning instructions, operators can adjust the vehicle's retrieval speed to complete the retrieval before strong winds arrive, ensuring the safety of equipment and personnel.

[0042] Furthermore, notifications and warnings, or audible and visual alarms, can be issued through wind speed warning platforms, operating machinery, or handheld wind speed monitoring terminals. In particular, using handheld wind speed monitoring terminals for wind speed warnings allows operators to promptly detect the warning even after the equipment has been powered off and moved away, enabling timely shutdown. Handheld wind speed monitoring terminals, such as... Figure 4 As shown.

[0043] In addition, if the operating machinery can automatically retract, then after the warning is issued, or after the warning reaches a certain level, the operating machinery can directly perform the retraction operation to avoid damage to the equipment caused by the operator not being able to retract the machinery in time.

[0044] The wind speed warning method for operating machinery provided by this invention predicts a third wind speed after a preset time interval based on the second wind speed detected by a wind speed detection device at the current moment, compares the first wind speed obtained from the meteorological station with the predicted third wind speed, and issues a wind speed warning based on the maximum wind speed. This method comprehensively considers the wind speed changes at the location of the operating machinery and the wind speed monitored by the meteorological station, thereby issuing a warning based on the maximum wind speed. This allows sufficient time for the operating machinery to be brought down, avoids damage to the operating machinery and other equipment when strong winds arrive, and ensures the safety of operators.

[0045] This embodiment provides a wind speed warning method for operating machinery, which can be used in the aforementioned wind speed warning platform. Figure 5 This is a flowchart of a wind speed warning method for operating machinery according to an embodiment of the present invention, such as... Figure 5 As shown, the process includes the following steps: Step S501: Obtain the first wind speed from the weather station and the second wind speed detected by the wind speed detection equipment at the current moment. For details, please refer to [link to relevant documentation]. Figure 3 Step S301 of the illustrated embodiment will not be described again here.

[0046] Step S502: Predict the third wind speed after a preset time interval based on the second wind speed. The preset time interval is determined in advance based on the operating machinery's closing time.

[0047] Specifically, step S502 above includes: Step S5021: Obtain the fourth wind speed of the previous moment detected by the wind speed detection device.

[0048] Specifically, in this embodiment of the invention, the wind speed detection device has a built-in data recording function, recording the wind speed data at each moment in real time during the detection of wind speed at the working position of the wheeled crane. Therefore, the wind speed early warning platform obtains the wind speed data collected by the wind speed detection device at each moment and, based on the second wind speed at the current moment... The fourth wind speed at the previous moment And based on the second wind speed at the current moment The fourth wind speed at the previous moment Predicting preset time intervals The third wind speed .

[0049] Step S5022: Calculate the wind speed difference between the second wind speed and the fourth wind speed, and perform an integral calculation on the wind speed difference based on a preset time interval to obtain the third wind speed.

[0050] Specifically, in this embodiment of the invention, the second wind speed is calculated. and the fourth wind speed Wind speed difference between This reflects the change in wind speed relative to the previous moment; positive values ​​indicate increased wind speed, and negative values ​​indicate decreased wind speed. Based on this, a preset time interval is used... For the integration interval, linear integration is performed based on wind speed changes to calculate the preset time interval. The third wind speed The calculation formula is as follows:

[0051] in, This invention predicts the wind speed after a preset time interval based on wind speed changes at the location of the operating machinery. It can dynamically monitor the wind force value after the preset time interval in real time, so as to respond more quickly to instantaneous changes in wind speed and improve the vehicle's adaptability in complex wind environments. Moreover, wind speed prediction based on integral calculation has the advantages of low cost and easy implementation, and is suitable for the operating scenarios of operating machinery.

[0052] In some optional implementations, embodiments of the present invention may also pre-build a wind speed prediction model based on a deep learning algorithm to learn the wind speed changes in the operating area of ​​the wheeled crane, and based on the second wind speed at the current moment. Predicting preset time intervals The fourth wind speed Among them, the integral prediction algorithm is simple and low-cost, while the model prediction algorithm is more complex and high-cost. The choice can be made according to actual needs, and no restrictions are imposed here.

[0053] Step S503: If the third wind speed is the maximum wind speed, then issue a wind speed warning based on the third wind speed.

[0054] Specifically, in the embodiments of the present invention, if This indicates that due to local terrain or instantaneous wind changes, the wind speed at the work site will exceed the macroscopic wind field intensity in the short term, therefore the third wind speed is directly used. As a baseline emergency response, i.e., based on the third wind speed Issue wind speed warnings.

[0055] The wind speed warning method for operating machinery provided by this invention predicts a third wind speed after a preset time interval based on the second wind speed detected by a wind speed detection device at the current moment, compares the first wind speed obtained from the meteorological station with the predicted third wind speed, and issues a wind speed warning based on the maximum wind speed. This method comprehensively considers the wind speed changes at the location of the operating machinery and the wind speed monitored by the meteorological station, thereby issuing a warning based on the maximum wind speed. This allows sufficient time for the operating machinery to be brought down, avoids damage to the operating machinery and other equipment when strong winds arrive, and ensures the safety of operators.

[0056] This embodiment provides a wind speed warning method for operating machinery, which can be used in the aforementioned wind speed warning platform. Figure 6 This is a flowchart of a wind speed warning method for operating machinery according to an embodiment of the present invention, such as... Figure 6 As shown, the process includes the following steps: Step S601: Obtain the first wind speed from the weather station and the second wind speed detected by the wind speed detection equipment at the current moment. For details, please refer to [link to relevant documentation]. Figure 5 Step S501 of the illustrated embodiment will not be described again here.

[0057] Step S602: Predict the third wind speed after a preset time interval based on the second wind speed. The preset time interval is determined in advance based on the operating machinery's closing time. For details, please refer to... Figure 5 Step S502 of the illustrated embodiment will not be described again here.

[0058] Step S603: Compare the first wind speed with the third wind speed to determine the maximum wind speed, and issue a wind speed warning based on the maximum wind speed.

[0059] Specifically, step S603 includes: Step S6031: If the first wind speed is the maximum wind speed, then obtain the first location information of the weather station and the second location information of the operating machinery.

[0060] Specifically, in the embodiments of the present invention, if This indicates that the wind field intensity over a large area is higher than the current and short-term forecast values ​​at the work site, which may indicate that the wind speed at the work site will increase as the macro wind field strengthens. Therefore, the first wind speed should be used. This serves as a baseline for early warning. However, the first wind speed monitored by the weather station... Since the distance to the wheeled crane is relatively far, it is necessary to estimate the first wind speed at the weather station. Will it cause any impact when it reaches the wheeled crane? This embodiment of the invention obtains the first location information of the weather station. Second position information of wheeled cranes Based on this, the wind speed impact is estimated.

[0061] Step S6032: Determine the horizontal distance between the weather station and the operating machinery based on the first location information and the second location information.

[0062] Specifically, in this embodiment of the invention, the farther the weather station is from the wheeled crane, the higher the first wind speed at the weather station. The smaller the impact on the wheeled crane, the better, based on the first position information Second position information Determine the horizontal distance between the weather station and the wheeled crane. This allows for the assessment of the first wind speed at the weather station. Impact on wheeled cranes.

[0063] In some alternative implementations, if the terrain of the work area is complex (such as mountainous areas), an altitude correction can be added, but the core is mainly horizontal distance, as the horizontal propagation of wind is the main influencing factor.

[0064] Step S6033: Calculate the estimated time interval for the wind to reach the operating machinery from the weather station based on the horizontal distance and the first wind speed.

[0065] Specifically, in this embodiment of the invention, it is assumed that the first wind speed monitored by the weather station... If the wind travels at a constant speed horizontally towards the area where the wheeled crane is located, then the estimated time interval between the wind reaching the wheeled crane from the weather station is... The calculation formula is as follows:

[0066] During the calculation process, the units of all variables need to be standardized to ensure the accuracy of the calculation results.

[0067] Step S6034: Compare the expected time interval with the preset time interval. If the expected time interval is less than the preset time interval, issue a wind speed warning based on the first wind speed.

[0068] Specifically, in the embodiments of the present invention, a preset time interval is used. It is the system's set early warning response window period, which is the period expected to be at least [time period missing]. Time warning allows for reserving time for wheeled cranes to retract and take precautions. Estimated time interval. This is the time it takes for the wind to travel from the weather station to the wheeled crane. Therefore, a preset time interval is used. Time interval from the expected time interval To make a comparison, if This indicates that the strong winds arrived later than the preset window (e.g., the preset window is 1 hour, and the strong winds arrived 2 hours later), and the risk is not imminent; if This indicates that strong winds will reach the wheeled crane within the preset warning window (e.g., preset for 1 hour, but strong winds will arrive in 15 minutes), posing an imminent risk. In this case, a wind speed warning should be triggered immediately, with the specific warning level determined based on the first wind speed. The invention determines the safe wind speed threshold. By calculating the estimated time interval between the wind speed at the location of the weather station and the location of the operating machinery, the invention can determine whether a wind speed warning is needed based on the estimated time interval and the preset time interval required for the machinery to be brought down. This is to avoid equipment damage or personal injury caused by insufficient time to bring down the machinery when strong winds from a distance arrive.

[0069] The wind speed warning method for operating machinery provided by this invention predicts a third wind speed after a preset time interval based on the second wind speed detected by a wind speed detection device at the current moment, compares the first wind speed obtained from the meteorological station with the predicted third wind speed, and issues a wind speed warning based on the maximum wind speed. This method comprehensively considers the wind speed changes at the location of the operating machinery and the wind speed monitored by the meteorological station, thereby issuing a warning based on the maximum wind speed. This allows sufficient time for the operating machinery to be brought down, avoids damage to the operating machinery and other equipment when strong winds arrive, and ensures the safety of operators.

[0070] This embodiment also provides a wind speed warning device for operating machinery, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0071] This embodiment provides a wind speed warning device for construction machinery, such as Figure 7 As shown, it includes: The wind speed acquisition module 701 is used to acquire the first wind speed of the weather station at the current moment and the second wind speed detected by the wind speed detection equipment.
