[0053] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0054] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0055] The specific application scenarios of this application are as follows: Figure 1 As shown, there are multiple types of electrical equipment installed on the wind turbine tower. During the inspection or maintenance of the electrical equipment, it is usually necessary for multiple people to cooperate with each other. The personnel on the tower carry out maintenance, and the personnel below the tower cooperate with the personnel on the tower to shut off the power, etc. In addition, other unrelated personnel at the bottom of the tower should be prevented from climbing to the top of the tower.

[0056] At present, multiple signal detectors, such as infrared detectors, are usually installed on the wind turbine tower to monitor the specific conditions of maintenance personnel in the tower and provide corresponding warning information to personnel outside the tower to ensure the safety of maintenance personnel in the tower. However, the above method cannot intelligently and accurately monitor the conditions of maintenance personnel in the tower, such as whether there are multiple maintenance personnel, whether multiple maintenance personnel have accurately reached the correct maintenance position when climbing the tower, etc.

[0057] The present application provides a method for wind turbine tower-based anti-climbing warning, which aims to solve the technical problems in the prior art of wind turbine tower anti-climbing, such as the inability to accurately and intelligently detect the status of maintenance personnel in the tower and provide corresponding warnings.

[0058] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0059] Figure 2 A schematic diagram of a wind turbine tower anti-climbing warning method provided in an embodiment of the present application Figure 1 .like Figure 2 As shown, the method includes:

[0060] S201. Obtain maintenance information of a wind turbine tower, where the maintenance information includes a maintenance start time period and the number of maintenance personnel of the wind turbine tower.

[0061] Maintenance information includes the specific maintenance start time period, the number of personnel involved in the maintenance, and the specific maintenance content. The maintenance start time period includes the time period during which maintenance personnel can enter the wind turbine tower. For example, if one or more maintenance personnel plan to enter the wind turbine tower from 14:00 to 15:00 on a specific day, the time period from 14:00 to 15:00 is the maintenance start time period. The maintenance content includes comprehensive inspection, replacement and removal of various equipment, devices and parts on the wind turbine tower, including maintenance task description, list of required tools and equipment, safety measures and emergency plans, maintenance schedule, etc.; various equipment and devices may include but are not limited to wind turbine blades, generators, control systems, transmission devices, lubrication systems, and safety monitoring equipment. In addition, maintenance information also includes the tools and maintenance equipment used in the maintenance process, detailed descriptions of maintenance steps, any problems encountered and their solutions, and post-maintenance testing and verification results.

[0062] S202. Acquire first detection information of a first signal detection device on a wind turbine tower, wherein a first signal detection device is provided at the bottom of the wind turbine tower, and the first detection information is used to indicate a first personnel signal and a first personnel time of each personnel within a first time period.

[0063] By installing a first signal detection device at the bottom of the wind turbine tower, detection signals of the presence of one or more persons and the specific time when each detection signal is detected are detected in real time. The first signal detection device may be a proximity detector, etc., which can detect a person approaching or moving away from the first signal detection device, as well as the relative position of the person and the first signal detection device. Optionally, the first signal detection device may use an infrared detector to determine the presence of a person by sensing infrared radiation emitted by the human body. The detection information includes real-time detection signals of the person, such as the time when the person enters or leaves the wind turbine tower, the length of stay, and the number of people.

[0064] The first detection information includes the first personnel signal detected in real time by the first signal detection device for each person, and the time corresponding to the first personnel signal, and the first personnel signal of each person is detected in real time within the first time length, and the corresponding first personnel time. Since maintenance personnel need to enter the tower in turn to climb when climbing the wind turbine tower, the time for maintenance personnel to enter the tower is a continuous period of time, and the first time length of multiple people continuously entering the tower can be obtained. For example, if there are 10 maintenance personnel involved in this maintenance task, the first signal detection device will detect the first personnel signal of each maintenance personnel respectively, and record the specific time points of the first and last personnel entering the tower, thereby obtaining the first time length. The first detection information indicates the first personnel signal detected within the first time length and the corresponding time when the person signal is detected, that is, the first personnel time.

[0065] S203: Determine whether any unrelated personnel have entered the tower according to the maintenance information and the first detection information.

[0066] By obtaining the maintenance information and the first detection information, it is possible to effectively determine whether any unrelated personnel have entered the wind turbine tower, thereby preventing unrelated personnel from interfering with the maintenance work, helping to ensure the smooth progress of the maintenance work, and preventing unrelated personnel from entering the wind turbine tower without the knowledge of the maintenance personnel, thereby reducing the risk of accidents. The maintenance information includes the number of maintenance personnel, the start time period of maintenance, and the specific maintenance content, while the first detection information records the personnel signal and time detected by the first signal detection device. By comparing this information, it can be confirmed whether the personnel entering the tower matches the predetermined number of maintenance personnel. If the detected personnel signal exceeds the expected number, or the time period corresponding to the first duration is not in the start time period, measures can be taken immediately to prevent unrelated personnel from entering.

[0067] S204: If not, obtain second detection information of a second detection device, where a second signal detection device is disposed on the top of the wind turbine tower; the second detection information is used to indicate a second personnel signal and a second personnel time of each personnel within a second time period.

[0068] S205: If yes, an alarm signal is issued.

[0069] The second detection information includes a second detection device installed at the top of the wind turbine tower or at a maintenance position at a certain height from the bottom of the tower, which detects one or more personnel detection signals in real time, as well as the time corresponding to the detection signal. The second detection device can be an infrared sensor, an ultrasonic sensor or a camera, etc., which can provide dynamic data about the maintenance personnel at the high-altitude working position, and can also be used for comparison with the first detection information to further verify the activity trajectory and working status of the maintenance personnel. For example, by comparing the detection data at the bottom and top of the tower, it can be confirmed whether the maintenance personnel arrive at the designated maintenance location according to the predetermined time and order, thereby ensuring the orderly progress of the maintenance work.

[0070] When it is determined through step S203 that no irrelevant personnel have entered the tower, step S204 is performed next to obtain second detection information to monitor whether the maintenance personnel have arrived at the designated maintenance location as planned. Specifically, in step S204, since at least one person has arrived at the maintenance location, the duration of multiple people arriving at the maintenance location, i.e., the second duration, is obtained. The second detection device will record the detection signal and time information of the maintenance personnel at the top of the tower or the designated maintenance location in real time.

[0071] When it is determined through step S203 that an unrelated person has entered the wind turbine tower, step S205 will be immediately performed to sound an alarm, which will not only notify the maintenance personnel on site, but also the security personnel and other relevant management personnel. The alarm can be issued in a variety of ways, such as sound and light alarms, SMS notifications, emails, or real-time prompts through a dedicated security monitoring system. After receiving the alarm, the maintenance personnel and security personnel will quickly conduct an on-site survey to confirm the specific location and situation of the unrelated personnel. After confirming the presence of unrelated personnel, the security personnel will take measures to evacuate the unrelated personnel and guide the unrelated personnel to safely leave the tower area to ensure that they will not interfere with the ongoing maintenance work and will not be harmed due to unfamiliarity with the environment and operating procedures. At the same time, the security personnel will also conduct a comprehensive inspection of the maintenance site to ensure that all maintenance equipment and facilities are in normal condition and are not affected by the entry of unrelated personnel.

[0072] S206: Determine whether the person is climbing normally based on the first detection information, the second detection information and the maintenance information.

[0073] Through the first detection information, the second detection information and the maintenance information obtained above, it is determined that there is no unrelated personnel climbing, and the maintenance personnel normally enter the wind turbine tower, climb to the designated position, and perform maintenance and inspection work normally.

[0074] For example, the total climbing time is determined based on the first detection information and the second detection information. If the climbing time is longer than the preset climbing time, a danger may occur; or, if the number of people who climb to the maintenance point is determined based on the second detection information to be less than the number of people in the maintenance information, then someone may be in danger, and the system can immediately issue an alarm to notify the on-site management personnel or safety personnel to conduct inspections and rescue. This can prevent maintenance personnel from being unable to continue climbing due to injuries or other reasons after entering the tower. If this situation is not monitored and understood in a timely manner, it may cause more serious injuries to maintenance personnel or even cause a greater safety accident.

[0075] An anti-climbing warning method, device, equipment and storage medium based on a wind turbine tower provided in an embodiment of the present application, which obtains maintenance information of the wind turbine tower, wherein the maintenance information includes a maintenance start time period and the number of maintenance personnel of the wind turbine tower; obtains first detection information of a first signal detection device on the wind turbine tower, wherein a first signal detection device is provided at the bottom of the wind turbine tower, and the first detection information is used to indicate a first personnel signal and a first personnel time of each personnel within a first time period; determines whether an unrelated person has entered the tower according to the maintenance information and the first detection information; if so, issues an alarm signal, and if not, obtains a second detection device The top of the wind turbine tower is provided with a second signal detection device according to the second detection information prepared; the second detection information is used to indicate the second personnel signal and the second personnel time of each personnel within the second time period; according to the first detection information, the second detection information and the maintenance information, it is determined whether the personnel have climbed normally; the method provided in the present application can well judge whether there are irrelevant personnel entering the tower when repairing and inspecting the wind turbine tower, causing interference to the maintenance work and avoiding safety accidents; at the same time, it can also effectively monitor the situation of maintenance personnel in the tower to prevent maintenance personnel from being injured in the tower, and outside personnel cannot be informed in time, causing greater damage.

[0076] Figure 3 A schematic diagram of a wind turbine tower anti-climbing warning method provided in an embodiment of the present application Figure 2 Based on the above embodiment, how to judge whether there is an unrelated person entering the tower according to the maintenance information and the first detection information is described in detail. Figure 3 As shown, including:

[0077] S301. Determine a first duration according to the entry time of the first person and the entry time of the last person, wherein if no person enters within a preset duration after the current person, determine the current person as the last person.

[0078] The first duration can be determined by monitoring the first and last personnel entering the wind turbine tower. The determination of the last person can be achieved by presetting a time length. For example, when a person enters the tower, if no other person enters the tower within the preset time length, the person can be determined to be the last person. For another example, the maintenance personnel include personnel 1, personnel 2, personnel 3 and personnel 4, who enter the tower in turn. When personnel 4 enters the tower, if the entry of personnel 5 is not detected within the preset time length (for example, 5 minutes), personnel 4 can be determined to be the last maintenance personnel to enter. At this time, the sum of the time from personnel 1 to personnel 4 entering the tower is the first duration. At the same time, effectively determining the last person can also help identify irrelevant personnel. For example, if after the last person enters, after 1 hour, personnel 5 is detected to enter the tower, personnel 5 can be determined to be an irrelevant person, and an alarm is immediately issued to notify the on-site management personnel and safety personnel to handle it, so as to prevent irrelevant personnel from interfering with the maintenance work or causing safety accidents.

[0079] S302: Determine whether the time overlap between the time period corresponding to the first duration and the maintenance start time period is greater than or equal to a preset threshold.

[0080] The maintenance start time period includes the time when one or more personnel enter the wind turbine tower and the start time when the personnel start maintenance of various equipment and devices. For example, the time period corresponding to the first duration is from 8:00 to 8:10 (10 minutes), and the maintenance start time period is from 8:05 to 8:15 (10 minutes). Due to uncontrollable factors such as traffic distance and weather, personnel may not arrive on time during the maintenance time period. Therefore, time redundancy considerations are given, and repetition is used to determine whether they are related personnel. The repetition can be calculated by overlapping the time period / the time period corresponding to the first duration. For example, the repetition in the above example can be calculated as 0.5. By comparing the repetition with the preset threshold, it is determined whether there are irrelevant personnel entering the tower. If not, then S303, if so, then S304.

[0081] S303. If not, it is determined that an unrelated person has entered the tower.

[0082] S304: If yes, determine whether the number of personnel in the first time period is consistent with the number of maintenance personnel.

[0083] S305: If yes, determine that no unrelated person enters.

[0084] After determining that no irrelevant personnel have entered the tower, determine whether the number of personnel detected within the first period is consistent with the number of maintenance personnel, and further determine whether any irrelevant personnel have entered. If they are consistent, then S305 further determines that no irrelevant personnel have entered the tower.

[0085] S306: If not, and the number is greater than the number of maintenance personnel, it is determined that irrelevant personnel have entered.

[0086] S307. If not, and the number is less than the number of maintenance personnel, record the irregular operation and issue an early warning.

[0087] If they are inconsistent, and the number of personnel in the first time period is greater than the number of maintenance personnel, then S306 determines that an irrelevant person has entered; if the number of personnel in the first time period is less than the number of maintenance personnel, then S307 records the irregular operation and issues an early warning. Through the two judgments, it is possible to more accurately determine whether an irrelevant person has entered the tower, and to accurately determine whether the maintenance personnel have performed standardized maintenance operations.

[0088] Figure 4 A schematic diagram of a wind turbine tower anti-climbing warning method provided in an embodiment of the present application Figure 3 Based on the above embodiment, how to determine whether the wind turbine tower is climbing normally according to the first detection information, the second detection information and the maintenance information is described in more detail. Figure 4 As shown, the method includes:

[0089] S401. Determine a second time duration based on the summit time of the first person and the summit time of the last person, wherein if no one reaches the summit within a preset time duration after the current person, determine the current person as the last person.

[0090] The second time period can be determined by the arrival of the first person at the maintenance position and the arrival of the last person at the maintenance position. To determine the time when the last maintenance person reaches the summit, a time period (preset time period) can be preset. When a maintenance person reaches the summit, if no other person reaches the summit within the preset time period, the maintenance person can be determined as the last person to reach the summit.

[0091] S402: Acquire climbing duration according to the first person time of the first person in the first detection information and the second person time of the last person in the second detection information.

[0092] In order to determine the climbing time of the entire maintenance team when one or more maintenance personnel are performing maintenance work, the first person time of the first person in the first detection information and the second person time of the last person in the second detection information are obtained. By calculating the time difference between the first person time and the second person time, the climbing time of the entire maintenance team can be determined. This time period reflects the total time required from the first maintenance personnel starting to climb to the last maintenance personnel successfully reaching the summit.

[0093] S403: Determine whether the climbing time is less than the preset climbing time, and whether the number of personnel within the second time determined according to the second detection information is consistent with the number of maintenance personnel corresponding to the tower top.

[0094] In order to better monitor the status of maintenance personnel, a preset climbing time is set to determine whether the climbing time is less than the preset climbing time, and whether the number of personnel within the second time determined by the second detection information is consistent with the number of maintenance personnel corresponding to the tower top.

[0095] S404: If yes, determine to climb normally.

[0096] S405: If not, it is abnormal climbing and an alarm signal is issued.

[0097] If yes, the climbing time is less than the preset climbing time, the number of personnel in the second time determined by the second detection information is consistent with the number of maintenance personnel corresponding to the tower top, and normal climbing is determined. If no, the climbing time is greater than or equal to the preset climbing time, the number of personnel in the second time determined by the second detection information is inconsistent with the number of maintenance personnel corresponding to the tower top, and it is abnormal climbing, and an alarm signal is issued.

[0098] Figure 5 A schematic diagram of a wind turbine tower anti-climbing warning method provided in an embodiment of the present application Figure 4 On the basis of the above embodiments, Figure 5 As shown, the maintenance information also includes the maintenance termination time period. If the personnel are climbing normally, it includes:

[0099] S501. Obtain third detection information of a third signal detection device on a wind turbine tower, wherein the third detection information is used to indicate a third personnel signal and a third personnel time of each personnel within a third time period; and the detection time of the third detection information is later than the detection time of the first detection information.

[0100] The third detection information is a personnel signal detected in real time by a third signal detection device arranged at the bottom of the wind turbine tower, and a personnel time corresponding to the personnel signal. The detection time of the third detection information is later than the detection time of the first detection information.

[0101] S502: Determine the actual maintenance duration according to the third personnel time of the last personnel in the third detection information and the first personnel time of the first personnel in the first detection information.

[0102] The actual maintenance time is determined by including the first person time of the first person among the maintenance personnel and the third person time of the last person. For example, the maintenance personnel include personnel 1...personnel 4, and the time when personnel 1 enters the tower and the time when personnel 4 leaves the tower after the maintenance is completed is the actual maintenance time.

[0103] S503: Obtain a target maintenance duration corresponding to the maintenance type, wherein the target maintenance duration is determined based on historical maintenance durations.

[0104] Maintenance types include different maintenance strategies and maintenance methods for different maintenance tasks. The target maintenance time corresponding to each maintenance type is determined by combining the historical maintenance time of multiple maintenance types.

[0105] S504: If the actual maintenance time is less than or equal to the target maintenance time, it is determined to be normal maintenance; otherwise, it is determined to be abnormal maintenance and an alarm signal is issued.

[0106] S505, obtaining the number of maintenance personnel corresponding to the third time period; the third time period is determined based on the departure time of the first person and the departure time of the last person, wherein, if no person leaves after the current person within a preset time period, the current person is determined to be the last person.

[0107] After the S504 step, after determining that the maintenance is normal, in order to ensure that all maintenance personnel in the entire maintenance team leave the tower safely after the maintenance is completed, the number of maintenance personnel corresponding to the third time length is obtained. Similarly, after a certain person leaves, within the preset time length, the third signal detection device does not detect the third detection information, then the person is determined to be the last person. Those skilled in the art can understand that the third signal detection device is a detection device set at the exit. If the exit is consistent with the entrance, the third signal detection device is the same device as the first signal detection device. The first signal detection device confirms that the person is a resigned person by changing the relative position.

[0108] S506: If the number of maintenance personnel corresponding to the third duration is less than the number of maintenance personnel corresponding to the first duration, it is determined that personnel are stranded and an alarm signal is issued.

[0109] By comparing the number of maintenance personnel corresponding to the third time length with the number of maintenance personnel corresponding to the first time length, it is determined whether the maintenance personnel performing the maintenance task have all safely left the tower after entering and completing the maintenance. If the number of maintenance personnel corresponding to the third time length is less than the number of maintenance personnel corresponding to the first time length, it is determined that personnel are stranded and an alarm signal is issued to ensure that every person entering the tower can leave the tower.
