Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-3 The technical solution provided by the present invention specifically includes the following embodiments: Embodiment 1: A tower collapse prevention early warning method based on wind turbine tower data monitoring, comprising a power generation component 1, the power generation component 1 is used for wind power generation; Monitoring component 2: A monitoring component 2 is provided at the bottom of the power generation component 1. The monitoring component 2 includes a wind turbine tower 201. The wind turbine tower 201 is used to support the power generation component 1. A first overturning monitoring system 202 is fixedly installed on the upper side of the wind turbine tower 201. The model of the first overturning monitoring system 202 is overturning monitoring system RH1200. Wind turbine tower base 3: A wind turbine tower base 3 is provided at the bottom of the wind turbine tower 201, and the wind turbine tower base 3 is used to fix the wind turbine tower 201.

[0020] Specifically, in this embodiment, an optional measuring point 204 is fixedly provided in the middle of the wind turbine tower 201, an output end of the first overturning monitoring system 202 is electrically connected to a collection device 203, an output end of the first overturning monitoring system 202 is fixedly connected to a communication cable 208, an output end of the communication cable 208 is fixedly connected to a second overturning monitoring system 4, the second overturning monitoring system 4 is located inside the wind turbine tower base 3, and the model of the second overturning monitoring system 4 is an overturning monitoring system RH1204; The models of the first overturning monitoring system 202 and the second overturning monitoring system 4 are overturning monitoring system RH1200 and overturning monitoring system RH1204 respectively. The overturning monitoring system RH1200 and the overturning monitoring system RH1204 are mainly used for angle data collection, analysis and early warning of the wind turbine tower 201.

[0021] The output end of the optional measuring point 204 is electrically connected to a gyroscope 205, the output end of the optional measuring point 204 is electrically connected to a vibration sensor 206, the output end of the optional measuring point 204 is electrically connected to a tilt sensor 207, and the receiving end of the optional measuring point 204 is electrically connected to the output end of the acquisition device 203; The gyroscope 205, the vibration sensor 206 and the tilt sensor 207 are mainly used in conjunction with the overturning monitoring system RH1200 and the overturning monitoring system RH1204 to collect data of the wind turbine tower 201; The gyroscope 205 can not only be used as an indicating instrument, but more importantly, it can be used as a sensitive element in the automatic control system, that is, as a signal sensor. As required, the gyroscope 205 can provide accurate signals such as azimuth, level, position, speed and acceleration, so as to complete the real-time monitoring of the wind power tower 201; The vibration sensor 206 is an inductive sensor. Based on the relative mechanical receiving principle of the vibration sensor 206, the vibration sensor 206 can convert the change of the measured mechanical vibration parameter into the change of the electrical parameter signal. Therefore, the vibration sensor 206 has two forms, one is a variable gap, and the other is a variable magnetic conductive area, so as to complete the real-time monitoring of the vibration information of the wind turbine tower 201; According to the basic physical principle, the inclination sensor 207 cannot measure the velocity within a system, but can measure its acceleration. If the initial velocity is known, the linear velocity can be calculated by integration, and then the linear displacement can be calculated. Therefore, it is actually an acceleration sensor using the inertia principle. When the inclination sensor 207 is stationary, that is, there is no acceleration in the lateral and vertical directions, then only the gravity acceleration acts on it, and the angle between the gravity vertical axis and the sensitive axis of the acceleration sensor is the tilt angle. The inclination sensor 207 in a general sense is a static measurement or a quasi-static measurement. Once there is external acceleration, the acceleration measured by the acceleration chip includes the external acceleration, so the calculated angle is inaccurate. Therefore, the gyroscope 205 is provided to complete the data monitoring of the external acceleration, thereby improving the accuracy of the monitoring data of the inclination sensor 207.

It is a complex network interconnection device and is only used for interconnection between two networks with different high-level protocols. The wind farm ring network 7 is a ring topology composed of a group of IEEE802.1 compatible Ethernet nodes. Each node is connected to the other two nodes through a ring port based on 802.3 media access control, and the Ethernet MAC can be carried by other service layer technologies. All nodes can communicate directly or indirectly. It is mainly used for Internet connection of server 8, and the tower-based ring network switch 6 is mainly used to import the data transmitted by the communication gateway 5 into the wind farm ring network 7, so that the server 8 can store data.

[0023] The first overturning monitoring system 202 and the second overturning monitoring system 4 are both used for collecting, analyzing and providing early warning of the inclination angle data of the wind turbine tower.

[0027] The server 8 is used to store data transmitted by the wind farm ring network 7 , and the host computer software 9 is used to acquire and process the data stored in the server 8 in real time.

Finally, the inclination of the wind turbine tower 201 relative to the second overturning monitoring system 4, the parallelism and verticality of the two components are measured by the inclination sensor 207, and the measured angle data is then transmitted to the collection device 203 through the optional measuring point 204 for pre-storage.
