[0022] Due to special conditions or extreme weather conditions, such as wind, sand, strong light, fog, salt spray, and other weather factors, measurements can be affected, reducing measurement accuracy and requiring high labor and equipment costs. Therefore, a high-precision and low-cost wind turbine device and wind turbine intelligent monitoring and measurement system that can eliminate these influencing factors is needed.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that many technical details are provided in each embodiment of the present invention to enable the reader to better understand the present application. However, even without these technical details and the various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and referenced to each other under the premise that there is no contradiction.

[0024] One embodiment of the present utility model relates to a wind turbine device, comprising: a reference station, a mobile station, a wind turbine tower and a wind turbine blade; wherein the reference station is installed on the wind turbine tower; the mobile station is installed on the tip of the wind turbine blade; the mobile station is used to obtain the distance between the wind turbine blade and the wind turbine tower in real time based on the position information of the reference station and the position information of the mobile station itself. In an embodiment of the present invention, a reference station is installed on a wind turbine tower and a mobile station is installed on a wind turbine blade. The position of the tower is determined by the position information of the reference station, and the position of the blade is determined based on the position information of the mobile station and the position information of the reference station. Thus, the distance between the wind turbine blade and the wind turbine tower is determined based on the position of the tower and the position of the blade, thereby determining whether there is a safety hazard. Since the distance between the wind turbine tower and the blade is not measured by visual measurement calculation, the distance between the wind turbine tower and the blade is measured only by the positioning function of the reference station and the mobile station, which reduces the measurement requirements under extreme environmental conditions and improves the measurement accuracy of the wind turbine tower and blade in bad weather. In addition, the measurement of the distance between the wind turbine tower and the blade using the position information of the mobile station and the reference station is conducive to improving the actual measurement accuracy, further improving the monitoring accuracy of the tower and blade distance, thereby improving the safety and controllability of the wind turbine device during operation. The following is a detailed description of the implementation details of the wind turbine device of the embodiment of the present invention. The following content is only provided for the convenience of understanding and is not required for the implementation of this solution.

[0025] In some embodiments of the present invention, Figure 1 As shown, the base station includes a first positioning module 101 and a first communication module 102; wherein, the first positioning module 101 is connected to the first communication module 102; the first positioning module 101 is used to determine the position information of the tower through the Global Navigation Satellite System (GNSS) and transmit the position information of the tower to the first communication module 102; the first communication module 102 is used to transmit the position information of the tower to the cloud server in RTCM data format.

[0026] In some embodiments of the present invention, Figure 2As shown, the base station also includes a sensor module 103, a first USB interface module 104 and a first SIM card module 105; the sensor module 103, the first USB interface module 104 and the first SIM card module 105 are respectively connected to the first communication module 102; the sensor module 103 is used to obtain the status data of the tower and transmit the status data of the tower to the first communication module 102; the first communication module 102 is also used to transmit the status data of the tower to the cloud server; the first USB interface module 104 is used to transmit the data in the first communication module 102 to an external device through the USB interface; the first SIM card module 105 is used to send the data in the first communication module 102 to an external device.

[0027] Specifically, the main function of the base station is to provide data such as the latitude, longitude, and altitude of the tower, as well as differential data, and to send the data information to the cloud server via the 4G network. The first positioning module 101 in the base station needs to use a dual-band, multi-constellation GNSS module, such as a GNSS module that can track L1+L5 frequency band signals of multiple visible satellites, to reduce the multipath effect in urban canyons and improve the positioning accuracy of the tower; and, as a base station, the first positioning module 101 outputs data in RTCM format to the first communication module 102. It is worth noting that the first positioning module 101 has an antenna for receiving GNSS signals. The first communication module 102 in the base station uses an industrial-grade wireless communication module that supports diversity reception function, such as a module that supports LTE, WCDMA and GSM network types, to improve the global frequency band coverage of the first communication module 102 and enhance the communication transmission effect of the base station. The sensor module 103 in the base station uses a multi-type integrated sensor module 103, such as a wind speed sensor that can measure wind speed, a displacement sensor that measures tower displacement, tower verticality, and tower settlement height, or an alarm sensor for warnings. This allows the base station to not only provide tower location information but also upload data such as the tower itself and environmental changes to a cloud server for comprehensive data logging. Furthermore, the first USB interface module 104 enables data transmission from the first communication module 102, and the first SIM card module 105 provides a 4G network for the first communication module 102 to communicate with the cloud server.

[0028] In some embodiments of the present invention, Figure 3As shown, the mobile station includes a second positioning module 201 and a second communication module 202; wherein, the second positioning module 201 is connected to the second communication module 202; the second positioning module 201 is used to determine the high-precision position information of the wind turbine blades through GNSS, and transmit the high-precision position information of the wind turbine blades to the second communication module 202; the second communication module 202 is used to transmit the high-precision position information of the wind turbine blades to the cloud server.

[0029] In some embodiments of the present invention, after receiving the tower position information sent by the cloud server, the second communication module 202 transmits the tower position information to the second positioning module 201. The second positioning module 201 then calculates high-precision position information of the wind turbine blades using a real-time kinematic (RTK) algorithm based on the tower position information and the satellite positioning information of the wind turbine blades obtained by the second positioning module 201 via GNSS satellites. Specifically, the GNSS positioning information obtained by the second communication module (i.e., the satellite positioning information of the wind turbine blades obtained by the second positioning module via GNSS satellites) is different from the high-precision position information of the wind turbine blades. The high-precision position information of the wind turbine blades is the high-precision position information obtained by RTK using the GNSS positioning information and the tower position information. RTK (Real Time Kinematic) is a real-time dynamic measurement technology based on carrier phase observation and is composed of three parts: a base station, a satellite data link, and a rover. A positioning receiving module is placed on the base station as a reference benchmark, and the GNSS satellite is continuously observed to obtain the base station's positioning data (i.e., the tower's location information), and the base station's positioning data is sent to the mobile station in real time; while receiving the GNSS satellite signal, the mobile station receives the positioning data (i.e., the tower's location information) transmitted by the base station, and based on the principle of relative positioning, the three-dimensional coordinates of the mobile station and their accuracy are calculated in real time (i.e., the coordinate differences △X, △Y, △H between the base station and the mobile station, plus the coordinates of each point obtained from the base coordinates, and the plane coordinates X, Y and altitude H of each point on the mobile station are obtained through coordinate conversion parameters), thereby calculating the high-precision position information of the wind turbine blades with centimeter-level accuracy.

[0030] In some embodiments of the present invention, Figure 4As shown, the mobile station also includes two GNSS antennas and an antenna switching module 203. The two GNSS antennas are mounted along the axis of the wind turbine blades, with the two GNSS antennas facing opposite directions. The two GNSS antennas are connected to the antenna switching module 203, which is used to switch the GNSS antenna currently used for receiving signals. The antenna switching module 203 is connected to the second positioning module 201. For example, when the wind turbine blades are perpendicular to the horizontal ground, the second positioning module 201 is mounted at the blade tips. In this case, both GNSS antennas are also perpendicular to the horizontal ground, with one GNSS antenna facing upward and the other facing downward. The angle between the two GNSS antennas is 180°. Because the wind turbine blades rotate continuously during operation, the blade tips drive the second positioning module 201 to continuously move and rotate during operation. If there is only one GNSS antenna, the reception effect is poor, and GNSS signals may not be received at certain angles, affecting the actual measurement accuracy. Therefore, in the embodiment of the present invention, two GNSS antennas facing in opposite directions are provided to enhance the reception effect during the operation of the mobile station. It should be noted that in actual production, the number and orientation of the GNSS antennas can be flexibly adjusted according to actual production needs, and this application does not impose any restrictions here.

[0031] In some embodiments of the present invention, the second positioning module 201 includes a differential mode and an RTK floating-point mode during calculation.

[0032] In some embodiments of the present invention, the mobile station further includes a second USB interface module 204 and a second SIM card module 205; the second USB interface module 204 and the second SIM card module 205 are respectively connected to the second communication module 202; the second USB interface module 204 is used to transmit the data in the second communication module 202 to an external device through the USB interface; the second SIM card module 205 is used to send the data in the second communication module 202 to an external device.

[0033] Specifically, the mobile station's primary function is to use differential data transmitted by the base station for RTK precise positioning. The second positioning module 201 in the mobile station should utilize a dual-band, multi-constellation GNSS module, such as one that can track L1+L5 frequency band signals from multiple visible satellites. This reduces multipath effects in urban canyons and improves tower positioning accuracy. A base station is a fixed, ground-based base station that provides a reference for the mobile station and is immovable during use. The mobile station, mounted on mobile equipment, uses differential data transmitted by the base station for RTK precise positioning. Similarly, the second positioning module 201, acting as a mobile station, also outputs data in RTCM format to the second communication module 202. To support RTK functionality, after receiving the base station's RTCM data from the cloud server, the second communication module 202 also transmits the base station's RTCM data, sent by the cloud server, to the second positioning module 201 via a UART interface. Based on this received data, the second positioning module 201 calculates high-precision position information for the wind turbine blades with optimal positioning accuracy. During the calculation process of the second positioning module 201, the calculation can be performed using differential mode or RTK floating-point mode. If the carrier phase ambiguity is determined, the second positioning module 201 enters RTK fixed mode, which can achieve centimeter-level high-precision positioning. The second communication module 202 in the mobile station uses an industrial-grade wireless communication module that supports diversity reception, such as a module that supports LTE (4G cellular network), WCDMA (3G cellular network), and GSM (2G cellular network). This improves the global frequency band coverage of the second communication module 202 and enhances the communication transmission effect of the base station. In addition, the second USB interface module 204 can realize data transmission of the second communication module 202; the second SIM card module 205 is used to provide the second communication module 202 with a 4G network to realize data transmission between the second communication module 202 and the cloud server. When performing differential positioning solution, the second communication module 202 is set to 4G transparent transmission mode, and the received differential data stream is transmitted to the ARM processor through the serial port. The ARM processor then sends the differential data stream to the second positioning module 201 through the serial port. The second positioning module 201 performs differential solution and outputs high-precision positioning results to the ARM processor in real time. If the mobile station detects that the straight-line distance between it and the base station is less than the preset safety distance, or is less than the preset safety distance for more than a preset number of times, or is less than the preset distance for more than a preset time, it can communicate with the safety control module or equipment connected to the wind turbine device to timely control the wind turbine device to shut down and issue a timely warning to prevent the wind turbine blades from being bent by the wind and causing the wind turbine tower to sweep the tower. It should be noted that the preset safety distance can be 4 to 6 meters. In actual production applications, the preset safety distance, preset number of times, and preset time can be flexibly adjusted according to actual needs, and this application does not impose any restrictions on this.

[0034] In some embodiments of the present invention, the base station and / or the mobile station use a patch SIM card. Using a patch SIM card effectively avoids the problem of SIM card electric shock and oxidation in harsh environments such as high temperature, high humidity, and high salt, thereby ensuring that the base station and the mobile station can effectively communicate.

[0035] In an embodiment of the present invention, a reference station is installed on a wind turbine tower and a mobile station is installed on a wind turbine blade, the position of the tower is determined by the position information of the reference station, and the position of the blade is determined based on the position information of the mobile station and the position information of the reference station, and the distance between the wind turbine blade and the wind turbine tower is determined based on the position of the tower and the position of the blade, so as to judge whether there is a safety hazard. Since the distance between the wind turbine tower and the blade is not calculated by visual measurement calculation, the distance between the wind turbine tower and the blade is calculated only by the positioning function of the reference station and the mobile station, which reduces the measurement requirements under extreme environmental conditions and improves the measurement accuracy of the distance between the wind turbine tower and the blade in bad weather. In addition, the measurement of the distance between the wind turbine tower and the blade by the position information of the mobile station and the reference station is conducive to improving the accuracy of the actual measurement, further improving the monitoring accuracy of the tower and blade distance, thereby improving the safety and controllability of the wind turbine device during operation.

Specifically, the cloud server is used to receive differential data from the base station and forward it to the mobile station.

[0042] Specifically, after the base station obtains the tower's location information through the GNSS satellite, it uploads the tower's location information and other data to the cloud server, and the cloud server forwards the tower's location information to the mobile station; the mobile station obtains the blade's location information based on the GNSS satellite; the mobile station calculates the distance between the tower and the blade based on the tower's location information and the blade's location information.
