Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine safety monitoring, and in particular to a wind turbine safety monitoring system based on an audio and video abnormality monitoring algorithm. Background Art

[0002] A wind turbine is a system that converts the kinetic energy of wind into electrical energy. A wind turbine includes a wind rotor and a generator. The wind rotor contains blades, a hub, and reinforcements. It has the functions of generating electricity by rotating the blades under wind power and rotating the generator head. A wind power source consists of a wind turbine, a tower supporting the turbine, a battery charge controller, an inverter, a load unloader, a grid-connected controller, and a battery pack.

[0003] When a wind turbine is generating electricity, the output frequency must be kept constant. This is very necessary for both wind turbine grid-connected power generation and wind-solar complementary power generation. To ensure the constant frequency of wind power, one way is to ensure the constant speed of the generator, that is, the constant speed and constant frequency operation mode. Because the generator is driven by the wind turbine through the transmission device, this method undoubtedly requires a constant speed of the wind turbine, which will affect the conversion efficiency of wind energy; another way is that the generator speed changes with the wind speed, and other means are used to ensure the constant frequency of the output power, that is, variable speed constant frequency operation. Therefore, a new monitoring system is very necessary. Traditional monitoring systems mostly use resistance changes for monitoring, and cannot accurately reflect the specific causes of abnormalities. Therefore, based on this, a wind turbine safety monitoring system based on audio and video abnormality monitoring algorithm is designed. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art and solve the technical problems raised in the background technology.

[0005] The present invention is implemented by the following technical scheme: A wind turbine safety monitoring system based on an audio and video abnormality monitoring algorithm comprises:

[0006] Audio and video data acquisition module, used to collect and summarize the speed and vibration frequency data of wind turbines;

[0007] The data storage module receives the data collected by the audio and video data collection module and makes a data storage table according to the date;

[0008] The data analysis module receives the data collected by the audio and video data collection module and derives the rationality range of the data based on the safety calculation;

[0009] The data feedback module receives the rationality range data from the data analysis module and sends an adjustment signal to the controller based on the current rotation speed and vibration frequency. The controller controls the rotation speed of the wind turbine.

[0010] The audio and video data acquisition module is connected to the data acquisition device through electrical signals, and is connected to the counter installed on the main shaft of the wind turbine through electrical signals. The counter is installed on multiple main and auxiliary shafts respectively.

[0011] Among them, the data feedback module is connected to the monitoring equipment, and the monitoring equipment is installed on each main and auxiliary shaft. When the speed is abnormal, an alarm signal is sent to the data feedback module through the signal device, and the data feedback module controls the speaker of the production line to sound.

[0012] There are multiple nodes on the monitoring node corresponding to the wind turbine, and each node is equipped with a loudspeaker for reminder.

[0013] Among them, the data storage module includes a data storage hard disk and a memory detection module. The data storage hard disk is used to record and store data related to rotation speed and vibration frequency, and the memory detection module detects the remaining memory of the data storage hard disk and automatically deletes it when the remaining memory of the data storage hard disk is insufficient.

[0014] When the memory detection module deletes data stored in the data storage hard disk, the data stored with the earliest date is deleted first.

[0015] The present invention provides a wind turbine safety monitoring system based on an audio and video abnormality monitoring algorithm. It has the following beneficial effects:

[0016] 1. The wind turbine safety monitoring system based on the audio and video abnormality monitoring algorithm installs counters and other information collectors on the main and secondary shafts of the wind turbine, and then collects information through the audio and video data acquisition module in conjunction with the data acquisition equipment. The data analysis module analyzes and compares the current speed and vibration frequency, calculates a reasonable value range, and determines whether there are safety hazards based on the speed and vibration frequency of each wind turbine. Then, an adjustment signal is sent to the controller, and the controller controls the drive motor to change the speed of the wind turbine to ensure the safety of the wind turbine.

[0017] 2. The wind turbine safety monitoring system based on the audio and video anomaly monitoring algorithm, the data storage module includes a data storage hard disk and a memory detection module, wherein the data storage hard disk is used to record and store relevant data, and the memory detection module detects the remaining memory of the data storage hard disk, and automatically deletes the data when the remaining memory of the data storage hard disk is insufficient. When the memory detection module deletes the data stored in the data storage hard disk, the data stored in the earliest date is deleted first, thereby reducing the risk of deleting important data and avoiding the storage process affected by insufficient data storage capacity.

[0029] Specifically, when the wind turbine is working, the data acquisition device collects the data recorded by the counter through electrical signals and uploads it to the audio and video data acquisition module. The audio and video data acquisition module collects and summarizes the speed and vibration frequency data of the wind turbine, and then uploads the data information to the data analysis module and the data storage module. The data analysis module receives the data collected by the audio and video data acquisition module, and derives the rationality range of the data based on safety calculations. The data feedback module receives the rationality range data of the data analysis module, and sends an adjustment signal to the controller based on the current speed and vibration frequency. The controller controls the rotation speed of the wind turbine, and determines whether there are safety hazards according to the speed and vibration frequency of each wind turbine. Then, by sending an adjustment signal to the controller, the controller controls the drive motor and changes the speed of the wind turbine to ensure the safety of the wind turbine.

[0030] In addition, the data storage module includes a data storage hard disk and a memory detection module, wherein the data storage hard disk is used to record and store relevant data, and the memory detection module detects the remaining memory of the data storage hard disk, and automatically deletes the data when the remaining memory of the data storage hard disk is insufficient. When the memory detection module deletes the data stored in the data storage hard disk, the data stored in the earliest date is deleted first, thereby reducing the risk of deleting important data and avoiding the storage process being affected by insufficient data storage capacity.
