[0041] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0042] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0043] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0044] Embodiment 1

[0045] As mentioned above, the main battlefield of future wind power development will be further expanded to remote areas where the communication environment needs to be further developed. In order to solve the problem that there is no communication base station or the base station signal is poor in remote environments such as the "sand desert" of wind turbines, the embodiment of the present invention relies on Beidou short message communication transmission technology to carry out the application research of short message communication in the transmission of fault information of key components of wind turbines, realize the real-time monitoring of wind power equipment status, timely understand the health status of wind turbines, and form a Beidou-based onshore high-power wind turbine fault transmission key technology system and terminal equipment.

[0046] In response to the data transmission security issues mentioned in the above background technology, this embodiment discloses a wind turbine fault transmission system based on Beidou short messages. Beidou equipment does not communicate directly with the wind turbine, but collects fault data through the central monitoring system of the booster station. In this embodiment, the sending end gateway server obtains wind turbine data through the on-site network switch, and transmits the wind turbine data to the Beidou sending end transceiver in the form of short messages. MQTT data parsing and Beidou equipment data parsing are implemented on the server side, and data grouping storage and private protocol grouping are implemented according to the parsed data. After that, the fault data and status data are transmitted to the Beidou equipment through the serial port. The above method further improves the security of data transmission.

[0047] Specifically, Figure 1 As shown, a wind turbine fault transmission system based on Beidou short message includes a sending end and a receiving end, wherein the sending end includes a Beidou sending end transceiver and a sending end gateway server, and the receiving end includes a Beidou receiving end transceiver, a receiving end gateway server and a database server, wherein:

[0048] The sending end gateway server is used to obtain wind turbine data through the on-site network switch and transmit the wind turbine data to the Beidou sending end transceiver in the form of short messages;

[0049] The Beidou sending end transceiver is used to receive the wind turbine data in the form of short messages, and forward the wind turbine data in the form of short messages to the Beidou receiving end transceiver via the Beidou satellite;

[0050] The Beidou receiving end transceiver is used to receive the wind turbine data in the form of short messages forwarded by the Beidou satellite and send it to the receiving end gateway server;

[0051] The receiving end gateway server is used for receiving and unpacking the wind turbine group data in the form of short messages, and storing the unpacked wind turbine group data in the database server.

[0052] The system of this embodiment deploys a set of Beidou equipment at the transmitting end and the receiving end respectively. It can be understood that the transmitting end is deployed at the wind farm side, while the receiving end is deployed at the ground center side. The transmitting end device transmits the fault data of key components of the unit from the wind farm side to the ground end of the central station in real time through the Beidou short message communication transmission technology.

[0053] More specifically, the sending end deploys a set of Beidou equipment and a set of gateway servers; the receiving end deploys a set of Beidou equipment, a set of gateway servers, and a set of fault data monitoring platform software. In order to solve the problem of no communication base station or poor base station signal in remote environments such as "Shagohuang", relying on Beidou short message communication transmission technology, the fault information of key components of wind turbines is transmitted to the central station in real time, realizing real-time monitoring of wind power equipment status, timely understanding of the health status of wind turbines, and forming a key technology system and terminal equipment for fault transmission of onshore high-power wind turbines based on Beidou.

[0054] To facilitate understanding, we will now combine Figure 1 , according to the direction of data transmission, the functions of each part of this system are introduced in turn.

[0055] Please refer to Figure 1 As shown, the wind turbine fault transmission system based on Beidou short message provided in this embodiment includes a sending end and a receiving end, wherein the sending end includes a Beidou sending end transceiver and a sending end gateway server, and the receiving end includes a Beidou receiving end transceiver, a receiving end gateway server, a database server, a host computer monitoring platform, etc.; the interface between the sending end and the receiving end Beidou device transceiver module is a 422 interface. Among them:

[0056] The sending end gateway server is used to receive real-time fault alarm information from the central monitoring system of the wind farm, and is located on the same core switch as the SCADA server. It parses the received MQTT message and packages it into a short message and sends it to the Beidou sending end transceiver;

[0057] The Beidou sending end transceiver is used to receive the fault information packaged into a short message form from the sending end gateway server, and send the short message to the Beidou receiving end transceiver via the Beidou satellite;

[0058] The Beidou receiving end transceiver is used to receive short messages sent from Beidou satellites, unpack the short messages and send them to the receiving end gateway server;

[0059] The receiving end gateway server is used to receive short messages from the Beidou receiving end transceiver device, unpack them and send them to the database server for storage;

[0060] The host computer monitoring platform is used to realize human-computer interaction, and based on the information in the database server, query the real-time fault information, historical fault information, fault statistics, equipment online status, alarm trend, etc. of the current wind turbine.

[0061] The Beidou sending and receiving devices developed in this embodiment are connected to the corresponding gateway server through the serial bus. Both sets of equipment are equipped with Beidou cards, so that the equipment has short message communication. The two sets of gateway servers developed are deployed on the wind farm side and the central station respectively to achieve network isolation between the field network and the Beidou equipment, and ensure the security of field data.

[0062] Furthermore, the Beidou sending end transceiver in this embodiment is connected to the sending end gateway server via a serial port bus, and the Beidou receiving end transceiver is connected to the receiving end gateway server via a serial port bus. The Beidou sending end transceiver and the Beidou receiving end transceiver transmit data packets in the form of short messages by wireless communication.

[0063] The Beidou transmitter-receiver does not communicate directly with the wind turbine generator set, but obtains the wind turbine generator set data through the transmitter-end gateway server and the on-site network switch. In this embodiment, in order to achieve the above purpose:

[0064] The sending end gateway server is connected to the field network switch via Ethernet, and the field network switch is also connected to the SCADA server via Ethernet, wherein:

[0065] The SCADA server is used to obtain wind turbine data and publish the wind turbine data through MQTT messages, wherein the wind turbine data includes wind turbine fault data and wind turbine status data;

[0066] The field network switch is used to obtain the MQTT message published by the SCADA server and forward it to the sending end gateway server;

[0067] The sending end gateway server is used to receive and parse MQTT messages, parse Beidou device data at the same time, store the parsed data in groups and perform private protocol grouping to form a data packet in the form of a short message, wherein the data packet in the form of a short message includes wind turbine group data and a heartbeat message between the Beidou device and the sending end gateway server.

[0068] Through the set on-site network switch and the sending end gateway server, the Beidou sending end transceiver can indirectly obtain the wind turbine data. After the data packet in the form of a short message is forwarded to the Beidou receiving end transceiver via the Beidou satellite, the Beidou receiving end transceiver forwards it to the receiving end gateway server. After the receiving end gateway server unpacks it, the required wind turbine data is stored in the database server. This completes the transmission of wind turbine data from the wind farm side to the ground side.

[0069] In order to better realize the human-computer interaction function, a host computer monitoring platform is also set up at the receiving end, which is used to receive the user's query information on the wind turbine set. Based on the query information, the wind turbine set information to be queried is obtained from the database server and displayed. The wind turbine set information to be queried includes real-time fault information, historical fault information, fault statistics, equipment online status or alarm trend.

[0070] It can be understood that the fault data monitoring platform software is deployed on the upper computer monitoring platform. The main function of the fault data monitoring platform software is to realize the monitoring of wind farm, wind turbine fault data and Beidou equipment information. The main modules include: map monitoring, wind farm fault alarm trend, Beidou equipment monitoring, real-time fault monitoring, historical fault query, fault statistics, equipment online status, system settings and other modules.

[0071] The host computer monitoring platform is developed using cross-platform tools and can be deployed to Windows, Linux and other mainstream operating systems. It has Beidou equipment map positioning display, fault information query, etc. The wind farm fault point table can be maintained and upgraded, and the alarm trend can be provided for analysis by the center staff.

[0072] like Figure 1 As shown, the host computer monitoring platform includes a ground network switch and a ground server, and the ground network switch is connected to the database server and the ground server respectively through Ethernet, wherein:

[0073] The ground server is used to respond to the user's query information on the wind turbine generator set, obtain the information to be queried in the database server through the ground network switch and display it.

[0074] Further:

[0075] The Beidou transmitter's transceiver has a data retransmission function: when faulty data is transmitted through the Beidou transmitter, it has a retransmission mechanism. When the transmission fails, the message is placed in the sending buffer and continues to be sent when the next sending task arrives;

[0076] The short message service frequency supported by Beidou equipment ranges from 1 second to 15 minutes, and different service frequencies support different message lengths. Different service frequencies can be selected according to different application scenarios.

[0077] During the data transmission process, it does not rely on traditional TCP, UDP and other protocols, but uses private protocol grouping to transmit fault and other data; it saves communication bandwidth by optimizing the combination of communication messages;

[0078] The system has strong adaptability to the working environment, has an IP68 waterproof rating, and an operating temperature between -40℃ and 65℃.

[0079] In this embodiment, the wind turbine fault transmission system based on Beidou short message has working steps mainly divided into wind farm side and center side, including:

[0080] Step 1: Implement MQTT data parsing, Beidou device data parsing, data grouping storage, and private protocol grouping on the sending end gateway server, and transmit the fault data and status data to the Beidou sending end transceiver through the serial port;

[0081] Step 2: The fault information is forwarded to the center via Beidou satellite;

[0082] Step 3: The Beidou receiving end transceiver on the center side sends the received fault data and status data to the receiving end gateway server on the center side.

[0083] Step 4: The receiving gateway server unpacks the short message and stores the data in the database.

[0084] When a wind turbine fails, the SCADA system will publish the parsed fault data to the application server of the central monitoring system through MQTT messages. The receiving gateway server will subscribe to the MQTT message and the data will be cached in the MongoDB database first. Since Beidou short messages have service frequency restrictions, the data will be packaged according to its own protocol and shortened to the shortest message for transmission to the Beidou sending device to save bandwidth.

[0085] The sending device sends data to the receiving Beidou device on the central side via the Beidou satellite. The data is sent to the receiving gateway server via the RS422 serial port. After unpacking, it is stored in the MongoDB database for query and call by the host computer monitoring platform. The data packet contains both real-time fault information of the wind turbine and heartbeat messages between the Beidou device and the server, which is convenient for monitoring the online status and signal strength of the equipment. The message sending has a retransmission mechanism to avoid the failure to receive unit fault information due to network failure or other reasons, thereby affecting the normal operation of the wind turbine.

[0086] Through the above methods, it is possible to realize wind farms without communication base stations or with poor base station signals in remote environments such as "Shagohuang". Through Beidou short message communication transmission technology, the fault information of key components of wind turbines can be transmitted to the central station in real time, realizing real-time monitoring of the status of wind power equipment, providing data analysis, and ensuring the safe operation of the units.

[0087] Reference Figure 2 As shown, it is the overall system structure diagram of the hardware of this embodiment. The Beidou device terminal consists of a DC-DC power supply circuit, a single-chip control module circuit, a short message communication module circuit, a positioning module circuit, and an RS422 communication circuit. The power supply adopts 24V power supply, and the 24V power supply supplies power to the single-chip module circuit, the short message module circuit, and the positioning module circuit through the DC-DC chip; it supports the RS422 serial port for wired data acquisition, information output, parameter setting and other functions.

[0088] The short message communication module circuit includes a baseband chip and a radio frequency chip, which are connected. The single-chip control module circuit communicates with the RS422 interface through a conversion chip.

[0089] like Figure 3 The following is a business architecture diagram of this embodiment, which includes the business layer, middleware layer, storage layer, network layer and operating environment:

[0090] The business layer is mainly used to realize status data upload, message combination optimization, form management, configuration management, fault data upload, communication QoS management, system log and data flow simulation;

[0091] The middleware layer is mainly used to implement RNSS parsing, data caching, file reading and writing, network operations, RDSS parsing, database addition, deletion, modification and query, time processing and custom operations;

[0092] The storage layer is mainly used for MongoDB database management;

[0093] The network layer is mainly used to implement TCP / IP management, MQTT management, Beidou short messages, etc.
