It can be understood that each blade load monitoring system control cabinet can be provided with a demodulator for obtaining blade load data, and the demodulator can be provided with an ETH interface.

[0086] It should be noted here that in actual application scenarios, the blade load system is installed on the blade baffle, and communication cables cannot be laid between the blade and the nacelle.

[0088] It should be noted here that in actual application scenarios, the distance between the data acquisition and monitoring control system main control cabinet and the data acquisition and monitoring control system server is too large, and data transmission can only be realized through optical cable connection, and at present stage, no other optical cable can be added between the nacelle and the booster station (in other words, at present stage, only one optical cable can be provided between the nacelle and the booster station).

[0090] In the existing wind turbine online monitoring system, the fan unit data can be obtained from the data acquisition and monitoring control system master control cabinet in real time, or the stored data can also be extracted from the server corresponding to the data acquisition and monitoring control system, and the blade load data can be obtained from the blade load system. The synchronization of the fan unit data and the blade load data cannot be effectively guaranteed, and there are problems such as wiring difficulty and few open ports.

[0091] Next, please refer to Figure 2 and Figure 3 , Figure 2 The overall flowchart of the wind turbine online monitoring data acquisition and communication method provided by the embodiment of the application is shown, Figure 3 The structure diagram of the wind turbine online monitoring system provided by the embodiment of the application is shown.

[0092] As Figure 2 shown, the wind turbine online monitoring data acquisition and communication method can at least include the following steps:

[0093] Step 202, obtaining the data acquisition operation of the user.

[0094] In the embodiment of the application, the wind turbine online monitoring data acquisition and communication method can be applied to the wind turbine online monitoring system. The wind turbine online monitoring system can at least include a blade load system arranged on the blade baffle, a data acquisition and monitoring control system installed in the nacelle, a network communication control box, and a pre-warning platform server arranged in the booster station.

The blade load monitoring system control cabinet can be provided with a first demodulator, a first wireless access module connected with the first demodulator, and a second wireless access module. It can be understood that the first wireless access module and the second wireless access module can transmit data through a wireless network, and the first wireless access module and the second wireless access module use different communication protocols and are set to be independent of each other. Here, the blade load data can be but not limited to the cross-section stress data of the blade and the blade rotating speed, which is not limited in the embodiment of the application.

[0095] It can also be understood that the first demodulator mentioned above can include but is not limited to an ETH1 interface for connecting with the first wireless access module and an ETH2 interface for connecting with the second wireless access module. The first wireless access module can be internally provided with a LAN interface and a wireless communication interface connected with the ETH1 interface in a wired manner, and the second wireless access module can be internally provided with a LAN interface and a wireless communication interface connected with the ETH2 interface in a wired manner.

[0096] It should be noted that when the blade load monitoring system includes at least two blade load monitoring system control cabinets, in addition to the blade load monitoring system control cabinet mentioned above including the first demodulator and the first wireless access module and the second wireless access module connected with the first demodulator, other blade load monitoring system control cabinets can be provided with a demodulator and a wireless access module connected with the demodulator, and the wireless access module can establish wireless pairing with the second wireless access module to realize data transmission between the wireless access module and the second wireless access module. For example, taking the other blade load monitoring system control cabinets as an example, the blade load monitoring system control cabinet 1 can be provided with a demodulator 1 and a wireless access module 1, the blade load monitoring system control cabinet 2 can be provided with a demodulator 2 and a wireless access module 2, and the wireless access module 1 and the wireless access module 2 can establish wireless pairing with the second wireless access module, so as to send the blade load data collected by the demodulator 1 and the blade load data collected by the demodulator 2 to the second wireless access module.

[0097] Among them, the network communication control box can include a third wireless access module, a first switch, a second switch and a fourth wireless access module, the first switch can be provided with an interface 1 for wired connection with the third wireless access module and an interface 2 for connection with the data acquisition and monitoring control system, so as to transmit the fan unit data obtained by the data acquisition and monitoring control system to the third wireless access module. The second switch can be provided with an interface 3 for wired connection with the fourth wireless access module, an interface 4 connected with the data acquisition and monitoring control system and an interface 5 connected with the early warning platform server by optical cable, so as to transmit the data received by the fourth wireless access module to the early warning platform server by optical cable. It should be noted that here, since the second switch is arranged in the cabin, the characteristic that only one optical cable can be arranged between the cabin and the booster station is used, and the optical cable is used to connect the second switch and the early warning platform server.

[0098] Here, the third wireless access module can be but not limited to establishing wireless pairing with the first wireless access module, and the third wireless access module can be internally provided with a LAN interface connected with the interface 1 in a wired manner and a wireless communication interface. The fourth wireless access module can be but not limited to establishing wireless pairing with the second wireless access module, and the fourth wireless access module can be internally provided with a LAN interface connected with the interface 3 in a wired manner and a wireless communication interface.

[0099] The data acquisition and monitoring control system can include a display screen and a master PLC controller, the display screen can be provided with an ETH interface for wired connection with the first switch, and the master PLC controller can be provided with an ETH1 interface for wired connection with the interface 2 and an ETH2 interface for wired connection with the interface 4. It can be understood that the ETH1 interface and the ETH2 interface are physically isolated and independent of each other. Here, the ETH1 interface of the master PLC controller is in the same network segment as the ETH1 interface of the first demodulator mentioned above, and the ETH2 interface of the master PLC controller is in another network segment as the ETH2 interface of the first demodulator mentioned above. The two network segments are independent of each other and do not interfere with each other, so as to improve the system reliability.

[0100] The early warning platform server can be directly provided with an ETH interface for wired connection with the second switch, or a third switch can be further provided in the booster station. The third switch can be provided with an interface for wired connection with the ETH interface of the early warning platform server and an interface for wired connection with the second switch, and the third switch and the second switch can be connected by optical cable. It can be understood that the server corresponding to the data acquisition and monitoring control system is further provided in the booster station. The server corresponding to the data acquisition and monitoring control system can be provided with an ETH interface for wired connection with the third switch.

[0101] Specifically, when the fan online monitoring is performed, the user's data acquisition operation can be obtained. The user's data acquisition operation can be but not limited to that a test personnel selects a control corresponding to data acquisition on a display interface of a control terminal, so that the wind turbine online monitoring system executes a data acquisition instruction according to the user's data acquisition operation.

[0102] It can be understood that the test personnel can also select a control corresponding to data acquisition on the display screen of the data acquisition and monitoring control system in the cabin. This is not limited.

[0103] Step 204, in response to the user's data acquisition operation, the first wireless access module and the third wireless access module are controlled to establish wireless pairing, and the second wireless access module and the fourth wireless access module are controlled to establish wireless pairing.

[0104] Specifically, after obtaining the data collection operation of the user, the wind power generator online monitoring system can but is not limited to control the first wireless access module to send a pairing request to the third wireless access module, so as to establish wireless pairing between the first wireless access module and the third wireless access module. Here, the third wireless access module stores a pairing identifier corresponding to the first wireless access module, so that the third wireless access module can quickly pair when receiving the pairing request of the first wireless access module. It can be understood that this time the third wireless access module can also send a pairing request to the first wireless access module, which is not limited here.

[0105] Possibly, after obtaining the data collection operation of the user, the wind power generator online monitoring system can but is not limited to control the second wireless access module to send a pairing request to the fourth wireless access module, so as to establish wireless pairing between the second wireless access module and the fourth wireless access module. Here, the fourth wireless access module stores a pairing identifier corresponding to the second wireless access module, so that the fourth wireless access module can quickly pair when receiving the pairing request of the second wireless access module. It can be understood that this time the fourth wireless access module can also send a pairing request to the second wireless access module, which is not limited here.

[0106] It should be noted that the operation of the wind power generator online monitoring system to control the first wireless access module and the third wireless access module to establish wireless pairing, and to control the second wireless access module and the fourth wireless access module to establish wireless pairing, can also be performed before obtaining the data collection operation of the user, so as to ensure the rapidity and synchronization of data monitoring.

[0107] Step 206, when the data collection and monitoring control system collects the wind turbine data, the data collection and monitoring control system controls the wind turbine data to be transmitted to the third wireless access module through the first switch by wire, and the third wireless access module wirelessly transmits the wind turbine data to the first wireless access module.

[0108] Specifically, when the data collection and monitoring control system collects the wind turbine data, the wind power generator online monitoring system can control the data collection and monitoring control system to wirelessly transmit the collected wind turbine data to the first switch, and the first switch wirelessly transmits the wind turbine data to the third wireless access module. It can be understood that the third wireless access module has established a wireless connection with the first wireless access module at this time, and the third wireless access module can wirelessly transmit the wind turbine data to the first wireless access module.

[0109] Step 208, when the first demodulator monitors the first blade load data, the wind turbine data and the first blade load data are integrated and processed to obtain target monitoring data.

[0110] Specifically, when the first blade load data of the blade is detected by the first demodulator of the blade load system, the wind turbine online monitoring system can but not limited to firstly determine whether the first wireless access module receives the wind turbine unit data wirelessly transmitted by the third wireless access module, and can integrate the first blade load data and the wind turbine unit data after determining that the wind turbine unit data is received, to obtain target monitoring data, which can effectively guarantee the synchronization of the first blade load data and the wind turbine unit data.

[0111] As an option of the embodiment of the present application, the blade load system further comprises a second demodulator and a fifth wireless access module connected with the second demodulator.

[0114] When the second demodulator monitors the second blade load data, controlling the fifth wireless module to wirelessly transmit the second blade load data to the second wireless access module;

[0115] According to the preset weight, the first blade load data and the second blade load data are combined and calculated to obtain target blade load data;

[0116] The wind turbine unit data and the first blade load data are integrated to obtain the target monitoring data, comprising:

[0119] Specifically, after the second blade load data of the corresponding blade is collected by the other blade load monitoring system control cabinet, the second blade load data can be wirelessly transmitted to the second wireless access module by the fifth wireless module of each blade load monitoring system control cabinet, to realize the collection of the blade load data of all blades.

[0120] Further, after the second radio access module obtains the blade load data of all the blades, the blade load data of all the blades can be classified, for example, the blade load data of blade 1 includes A1, B1 and C1, the blade load data of blade 2 includes A2, B2 and C2, and the blade load data of blade 3 includes A3, B3 and C3. After classification, the target blade load data of all the blades can be represented as (A1, A2, A3, B1, B2, B3, C1, C2, C3).

[0121] Of course, in the embodiment of the present application, the blade load data of all the blades can also be combined according to the preset weight, for example, the blade load data of blade 1 includes A1, B1 and C1, the blade load data of blade 2 includes A2, B2 and C2, and the blade load data of blade 3 includes A3, B3 and C3. The weight corresponding to blade 1 is 0.3, the weight corresponding to blade 2 is 0.4, and the weight corresponding to blade 3 is 0.3. After combination, the target blade load data of all the blades can be represented as (0.3*A1+0.4*A2+0.3*A3, 0.3*B1+0.4*B2+0.3*B3, 0.3*C1+0.4*C2+0.3*C3).

[0122] As another option of the embodiment of the present application, after obtaining the wind turbine unit data and the target blade load data, the wind turbine unit data can be feature extracted to obtain a first feature vector corresponding to the wind turbine unit data. Then, the target blade load data can also be feature extracted to obtain a second feature vector corresponding to the target blade load data. The feature extraction method of the wind turbine unit data can be consistent with the feature extraction method of the target blade load data, and in order to ensure the effectiveness of the feature vector, the first feature vector and the second feature vector can also be normalized.

[0123] Further, the first feature vector and the second feature vector can be input into the trained convolutional neural network to output target monitoring data from the convolutional neural network. It can be understood that the target detection data here can include data at different times, and each time data includes data corresponding to the wind turbine unit data and data corresponding to the target blade load data.

[0124] Of course, in the embodiment of the present application, the target detection data can also be obtained by other methods, which are not limited herein.

[0125] It should be noted that the wind turbine online monitoring system can obtain the target monitoring data by controlling the processor of the blade load system, but it is not limited to this, and it is not limited to this in the embodiment of the present application.

[0126] Step 210, controlling the second wireless access module to wirelessly transmit the target monitoring data to the fourth wireless access module, and wire the target monitoring data to the early warning platform server by the second switch.

[0127] Specifically, after obtaining the target monitoring data, the wind turbine online monitoring system can control the second wireless access module to wirelessly transmit the target monitoring data to the fourth wireless access module, and wire the target monitoring data to the second switch by the fourth wireless access module. At this time, after receiving the target monitoring data, the second switch can also wire the target monitoring data to the early warning platform server through an optical cable, not only effectively ensuring the synchronicity of the blade load data and the wind turbine unit data, but also timely analyzing the blade load data and the wind turbine unit data to avoid potential risks. It can be understood that after obtaining the blade load data and the wind turbine unit data, the early warning platform server can, but is not limited to, combine the wind turbine unit data to determine whether the blade load data is abnormal, for example, when the wind turbine unit data of each blade is consistent, it is found that the cross-section stress data of a certain blade is significantly lower than that of other blades, and the early warning information representing the damage of the blade can be sent to the test personnel.

[0128] As another optional embodiment of the present application, after integrating and processing the wind turbine unit data and the first blade load data to obtain the target monitoring data, before controlling the second wireless access module to wirelessly transmit the target monitoring data to the fourth wireless access module, it further includes:

[0129] extracting a first string from the wind turbine unit data in a first preset order, and normalizing the first string;

[0130] taking the processed first string as a first key, and encrypting the target monitoring data based on the first key;

[0131] controlling the second wireless access module to wirelessly transmit the target monitoring data to the fourth wireless access module, including:

[0132] controlling the second wireless access module to wirelessly transmit the encrypted target monitoring data to the fourth wireless access module, and controlling the first wireless access module to wirelessly transmit the first key to the third wireless access module.

[0133] Specifically, after obtaining the target monitoring data, in order to avoid the target monitoring data from being stolen or damaged in the transmission process, the wind turbine online monitoring system can further extract a first string containing multiple characters from the wind turbine unit data according to a preset first preset order, and perform normalization processing on the first string, so that all characters in the first string have uniformity. The first preset order can be, but is not limited to, extracting the mth character to the nth character from the wind turbine unit data in the order from left to right, m is less than n, and m and n are both positive integers.

[0134] Further, the first string after normalization processing can be used as a first key to perform asymmetric encryption processing on the target detection data, and the encrypted target detection data can be wirelessly transmitted to the fourth wireless access module through the second wireless access module, and the first key can be wirelessly transmitted to the third wireless access module through the first wireless access module. This way can effectively protect the integrity and security of the target monitoring data.

[0135] Further, after receiving the first key and the encrypted target monitoring data in the cabin, the target monitoring data can be decrypted based on the first key, and then the decrypted target monitoring data is wirelessly transmitted to the early warning platform server through the optical cable and the second switch.
