Description

Technical Field

[0001] This invention relates to the field of wind turbine blade manufacturing technology, and more specifically to a wind turbine blade production monitoring system. Background Technology

[0002] With the depletion of non-renewable energy sources and the development of wind power generation technology, the market for wind turbine blades is expanding, and wind turbine blades are becoming increasingly larger. Simultaneously, the quality control of blade production is becoming increasingly stringent. Most wind turbine blades are manufactured using vacuum injection molding of composite materials. The vacuum injection process for composite materials is significantly affected by temperature. Low adhesive temperatures during injection can lead to slow injection rates and poor injection quality; high injection temperatures can cause premature curing of the adhesive, resulting in product scrap. Therefore, precise temperature control during blade manufacturing is essential. Appropriate production temperatures can improve both blade production speed and quality.

[0003] Currently, temperature data during blade production is lost as the production control process flows, and most data cannot be effectively stored. If quality problems exist after blade production, it is difficult to find the specific cause, or it is difficult to trace temperature runaway problems caused by improper operation during production. By measuring and recording temperature through a temperature monitoring system, production quality problems caused by temperature can be effectively reduced, and production quality can be greatly improved. Summary of the Invention

[0004] The purpose of this invention is to provide a wind turbine blade production monitoring system to solve the problems mentioned above, such as the loss of temperature production data during the blade production process as it flows through the production control process, the inability to effectively store most data, the difficulty in finding specific factors if quality problems exist in the blades after production is completed, and the difficulty in tracking temperature runaway problems caused by improper operation during the production process.

The acquisition time of the multiple infrared images of the main material is different.

[0014] The controller is also used to determine the adhesive flow path based on the position of the adhesive relative to the blade main material in the infrared image of the main material;

[0023] If the glue discharge temperature is higher than the second preset threshold, reduce the heating power of the mixer;

[0024] The first preset threshold is less than the second preset threshold.

[0025] Optionally, the temperature detection module is also used to detect the temperature of the adhesive solution to be added to the mixer;

[0026] The controller is also used to adjust the heating power of the mixer based on the temperature difference between the current dispensing temperature setting and the temperature of the adhesive to be added to the mixer.

[0045] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0046] In the embodiments of the present invention, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use.

[0047] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0048] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0049] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0050] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0051] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] Figure 1 This is a schematic diagram of the structure of the first wind turbine blade production monitoring system provided by the present invention; Figure 2 This is a schematic diagram of the structure of the second wind turbine blade production monitoring system provided by the present invention; Figure 3 This is a schematic diagram of the temperature detection module provided by the present invention.

[0053] This embodiment provides a wind turbine blade production monitoring system, such as Figure 1 As shown, the system includes:

[0054] Temperature detection module 1 is used to acquire mold temperature, glue mixing temperature, blade main material temperature, glue discharge temperature, production termination temperature and ambient temperature in real time during the blade production process.

[0055] Controller 2, connected to the temperature detection module 1, is used to determine whether the received temperature of the blade production mold, the mixing temperature, the blade main material temperature, the glue discharge temperature, the production termination temperature and the ambient temperature are within their respective preset ranges, and to generate a corresponding alarm signal when any of them are not within their respective preset ranges.

[0056] Display module 3, connected to controller 2, is used to display the temperature of blade production mold, mixing temperature, blade main material temperature, glue discharge temperature, production termination temperature and ambient temperature in real time.

[0057] Alarm module 4, connected to controller 2, is used to generate corresponding alarm prompts when an alarm signal is received.

[0058] Specifically, in this embodiment, after receiving the mold temperature, mixing temperature, blade material temperature, discharge temperature, production termination temperature, and ambient temperature, the controller 2 binds the time and data acquisition device according to the data reception time and data channel. For each temperature data point, it generates a temperature curve with time sequence as the horizontal axis and temperature value as the vertical axis, providing a visual display of the data. The data displayed in the display module 3 can be all temperature data from the current moment to a preset time interval, such as the past hour or two hours.

[0059] Both the display module 3 and the alarm module 4 can be set in the production monitoring room or the factory production site. When the controller 2 determines that the received temperature of the blade production mold, the mixing temperature, the blade main material temperature, the glue discharge temperature, the production termination temperature and the ambient temperature are within the corresponding preset range, no control signal is generated. When the controller 2 determines that the received temperature of the blade production mold, the mixing temperature, the blade main material temperature, the glue discharge temperature, the production termination temperature and the ambient temperature are not within the corresponding preset range, an alarm signal is generated.

[0060] More specifically, the mold temperature is set to a first preset range, the mixing temperature is set to a second preset range, the blade material temperature is set to a third preset range, the discharge temperature is set to a fourth preset range, the production termination temperature is set to a fifth preset range, and the ambient temperature is set to a sixth preset range.

[0061] More specifically, in this embodiment, controller 2 is configured as a PLC controller, microcontroller, or digital controller, etc. Display module 3 is configured as a touch screen, etc. Production termination temperature is the overall temperature after the blade is bonded. The temperature of the blade main material can be marked and measured using a temperature measuring instrument, and a temperature record is generated and transmitted to controller 2 to form a main temperature measurement curve. Temperature adjustment measures are implemented based on feedback from curve fluctuations.

[0062] Furthermore, such as Figure 2 As shown, the system also includes:

[0063] Storage module 5, connected to temperature detection module 1, is used to store the blade production mold temperature, glue mixing temperature, blade main material temperature, glue discharge temperature, production termination temperature and ambient temperature received from temperature detection module 1.

[0064] Specifically, storage module 5 can be configured as a memory, hard disk, or server. During data storage, the temperature of the blade production mold, the mixing temperature, the temperature of the main blade material, the discharge temperature, the production termination temperature, and the ambient temperature are bound and stored according to the corresponding acquisition device name, device number, and acquisition time, facilitating subsequent data retrieval and analysis.

[0065] Furthermore, such as Figure 2 As shown, the system also includes:

[0066] The infrared image acquisition module 6 is connected to the controller 2 and is used to acquire multiple infrared images of the main material of the blade after the glue is injected and the glue is in a flowing state. The acquisition time of the multiple infrared images of the main material is different.

[0067] The controller 2 is also used to determine the adhesive flow path based on the position of the adhesive relative to the blade main material in the infrared image of the main material;

[0068] The display module 3 is also used to display the flow path of the adhesive liquid.

[0069] Furthermore, the controller 2 is specifically used for:

[0070] The adhesive temperature is determined based on the infrared image of the main material.

[0071] The positional change of the adhesive relative to the blade material is determined based on the adhesive temperature.

[0072] The adhesive flow path is determined based on the positional change of the adhesive relative to the blade material.

[0073] Specifically, since there is a temperature difference between the adhesive and the blade material, after the infrared image of the main material is acquired by the infrared image acquisition module 6, the different temperatures of the adhesive and the blade material can be used to visually reflect the position of the adhesive flow on the blade material. By observing the color depth of different areas in the infrared image of the main material, the positional change of the adhesive relative to the blade material can be determined, thereby determining the adhesive flow path.

[0074] Normally, the temperature of the adhesive is higher than that of the blade material itself. Therefore, the color depth of the area through which the adhesive flows is deeper than that of the area that does not flow through. By using image processing algorithms and edge detection algorithms, the positional change of the adhesive relative to the blade material can be accurately determined, thereby accurately determining the adhesive flow path.

[0075] Furthermore, the infrared image acquisition module 6 is an infrared camera or an infrared camera.

[0076] Specifically, infrared cameras are generally active infrared cameras. Their basic principle is based on the ability of ordinary CCD cameras to detect the spectral characteristics of infrared light (0.8µm to 1.05µm near-infrared). Alternatively, infrared thermal imagers can be used to acquire images of the main material. First, the infrared radiation emitted by the target itself is detected. Then, through photoelectric conversion and signal processing, the temperature distribution image of the target object is converted into a video image. This is achieved by combining electronic technology and computer software with infrared technology to detect and measure thermal radiation. The amount of heat radiated from the object's surface is measured by a thermally sensitive sensor, which detects different heat differences. Through electronic and software processing, images with varying brightness or color differences are presented.

[0077] In this embodiment, the temperature difference between the adhesive injected into the main material and the temperature of the main material itself is used to determine the positional change of the adhesive relative to the main material, thereby determining the flow path of the adhesive through multiple consecutive images. Through measurement and comparison, a resin flow curve is formed. Measurements are recorded at both the horizontal and vertical interfaces to synthesize a resin flow model, which serves as the theoretical basis for debugging the resin infusion process. Therefore, an infrared camera can capture a video image and extract consecutive image frames for analysis, or multiple images can be captured continuously by an infrared camera for analysis.

[0078] Furthermore, the controller 2 is connected to a glue mixer, which is used to mix and heat the glue solution. The controller 2 is also used for:

[0079] If the dispensing temperature is lower than the first preset threshold, increase the heating power of the mixer;

[0080] If the glue discharge temperature is higher than the second preset threshold, reduce the heating power of the mixer;

[0081] The first preset threshold is less than the second preset threshold.

[0082] Specifically, in this embodiment, the glue mixer has an automatic temperature regulation function. First, the glue discharge temperature of the glue mixer is determined through the wind turbine blade manufacturing process. This glue discharge temperature is the optimal temperature for bonding wind turbine blades. Therefore, during the production process, the glue discharge temperature should be kept as constant as possible. Thus, it is necessary to monitor the glue mixing temperature and the glue discharge temperature in real time so that when the glue discharge temperature is lower than a first preset threshold, the heating power of the glue mixer is increased; when the glue discharge temperature is higher than a second preset threshold, the heating power of the glue mixer is reduced.

[0083] More specifically, in this embodiment, it is assumed that the total amount of adhesive used for each heating and stirring is equal. The heating power of the mixer is controlled using the following method: First, based on historical data, the heating power of the mixer when the dispensing temperature is at a preset temperature threshold is determined. This preset temperature threshold is the average of a first preset threshold and a second preset threshold. Then, data fitting is performed to obtain the following heating power control formula. When the dispensing temperature is below the first preset threshold, the heating power of the mixer is increased; when the dispensing temperature is above the second preset threshold, the heating power of the mixer is decreased. The heating power is adjusted using the following heating power control formula:

[0084]

[0085] Where P is the actual heating power of the mixer; P0 is the heating power of the mixer when the outlet temperature is at the preset temperature threshold; T 第一The first preset threshold; T 第二 The second preset threshold; T 出 The collected discharge temperature is α; α is the fitting coefficient, which is determined by fitting analysis of historical data.

[0086] By controlling the heating power of the mixer using the above heating power control formula, precise control of the discharge temperature of the mixer can be achieved, reducing fluctuations in the discharge temperature and further improving production quality.

[0087] Furthermore, the temperature detection module 1 is also used to detect the temperature of the adhesive solution to be added to the mixer;

[0088] The controller 2 is also used to adjust the heating power of the mixer according to the temperature difference between the current dispensing temperature setting and the temperature of the adhesive to be added to the mixer.

[0089] Furthermore, such as Figure 3 As shown, the temperature detection module 1 includes: a temperature and humidity meter 11, multiple temperature sensors 12, and multiple infrared thermometers 13;

[0090] The temperature and humidity meter 11 is installed in the factory area to obtain the ambient temperature in the factory area;

[0091] Multiple temperature sensors 12 are respectively installed inside the mold, inside the mixer, and at the outlet of the mixer to obtain the mold temperature, mixing temperature, and outlet temperature.

[0092] Multiple infrared thermometers 13 are installed in the factory area, with their measuring heads aimed at the main blade material to obtain the temperature of the main blade material and the production termination temperature.

[0093] Specifically, using different devices to collect data for different temperature parameters can ensure the accuracy of data collection and reduce overall costs.

[0094] In this embodiment, the temperature and humidity meter 11 is fixedly installed in the production workshop (factory area) of the fan blade by a bracket, and can obtain the ambient temperature in the production workshop. Specifically, since the fan blade has a certain length, multiple temperature and humidity meters 11 can be set to detect the ambient temperature of the corresponding areas of the head, middle and tip of the fan blade, so as to control the ambient temperature in turn.

[0095] Multiple temperature sensors 12 are configured, spaced apart inside the mold of the fan blades to acquire the mold temperature. First, the mold is divided into regions, and a single heating zone is planned. Temperature sensors 12 and heating wires are installed inside the heating zone. Based on the monitored mold temperature data, the data is transmitted to the controller. The controller adjusts the heating power of the heating wire to achieve temperature control, thereby realizing automatic adjustment of the mold temperature. Multiple temperature sensors 12 are also set inside the mixing machine to acquire the mixing temperature, and a temperature sensor 12 is set at the outlet of the mixing machine to acquire the outlet temperature.

[0096] The infrared thermometer 13 is fixedly installed in the production workshop of the wind turbine blades by a bracket. The temperature measuring head of the infrared thermometer 13 is aimed at the wind turbine blades. Since the wind turbine blades have a certain length, multiple infrared thermometers 13 are also set up to obtain the temperature of the main material of the blades and the production termination temperature.

[0097] Furthermore, the temperature sensor 12 is a thermocouple temperature sensor.

[0098] Specifically, in this embodiment, the temperature sensor 12 is configured as a thermocouple temperature sensor, which helps to improve the accuracy and reliability of the collected data. Thermocouple temperature sensors have advantages such as stable performance, flexible use, and high reliability.

[0099] Furthermore, the alarm module 4 is an audible and visual alarm.

[0100] Specifically, audible and visual alarms are used to provide dual alerts through sound and light, ensuring that monitoring personnel are informed in a timely and efficient manner so that maintenance and equipment control can be carried out.

[0101] The optional embodiments of the present invention have been described in detail above with reference to the accompanying drawings.

[0102] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not describe the various possible combinations separately.

This program is stored in a storage medium and includes several instructions to cause a microcontroller, chip, or processor to execute all or part of the steps of the methods described in the various embodiments of this application.
