Description

Technical Field

[0001] This application relates to the field of new energy technology, and more specifically, to a vacuum detection system for a solar collector tube, a detection and control method thereof, electronic equipment and storage medium. Background Technology

[0002] High-temperature solar collector tubes are the core components of linear concentrated solar thermal power (CSP) systems, converting solar energy into heat. Their vacuum performance significantly impacts the thermal efficiency and economic viability of the system. A high-temperature solar collector tube consists of a metal inner tube with a selective absorption film and a glass tube coaxially surrounding it. The annular space between the glass tube and the metal inner tube is evacuated to create a vacuum zone. This vacuum process reduces heat loss by weakening convective heat transfer within the space and also protects the selective absorption film from oxidation.

[0003] Vacuum failure in high-temperature solar collector tubes has always been a major problem in linear concentrated solar thermal power generation systems. According to the heat loss mechanism of the collector tube, heat loss mainly originates from radiative heat loss through the selective absorption film of the inner metal tube and convective heat loss in the annular space. Once the vacuum in the annular space of the high-temperature solar collector tube fails, heat loss increases significantly, and the selective absorption film of the inner metal tube also degrades due to high-temperature oxidation, resulting in a significant reduction in the thermal efficiency of the collector tube. In particular, in recent years, it has been discovered that during operation, hydrogen gas generated from the decomposition of the heat transfer oil within the collector tube can permeate into the annular space, leading to a decrease in vacuum and a sharp increase in heat loss, resulting in "collector tube overheating." This overheating phenomenon exceeds four times that of collector tubes with intact vacuum performance, ultimately causing the system to lose more than 20% of its revenue annually, resulting in significant economic losses. Therefore, it is necessary to effectively monitor the vacuum status of the annular space within the tube so that timely measures can be taken when a decrease in vacuum occurs to avoid significant heat loss to the system. Summary of the Invention

[0004] In view of this, this application provides a vacuum degree detection system for solar collector tubes and its detection and control method, device, electronic equipment and storage medium, for real-time detection of the vacuum degree of high-temperature solar collector tubes in linear concentrating solar thermal power generation systems, so as to avoid the large heat loss of the system caused by the decrease in vacuum degree.

[0018] Optionally, the step of using a temperature detection device to collect the first and second temperature values ​​of the target heat collector tube includes the following steps:

[0019] The flight vehicle is controlled to hover directly above the target heat collection tube, and the temperature of the glass tube is detected based on an infrared thermal imager to obtain the first temperature value;

[0020] The flight vehicle is controlled to hover directly above the target heat collection tube, and the lens of the low emissivity infrared thermometer is controlled to maintain a distance of 0.1 to 1 m from the glass tube.

[0021] Optionally, the vacuum degree of the target heat collector tube is obtained by calculating the first temperature value and the second temperature value using a preset algorithm, including the following steps:

[0022] The vacuum level is obtained by looking up the temperature-vacuum level MAP based on the first temperature value and the second temperature value.

[0023] Alternatively, the vacuum level can be obtained by calculating the first temperature value and the second temperature value based on a pre-trained neural network model.

[0029] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0031] Figure 2 This is a flowchart of a detection control method according to an embodiment of this application;

[0032] Figure 3 This is a block diagram of an electronic device according to an embodiment of this application. Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Figure 1 This is a schematic diagram of a vacuum detection system for a solar collector tube according to an embodiment of this application.

[0035] like Figure 1 As shown, the vacuum detection system for solar collector tubes in this embodiment is used to detect the vacuum level of high-temperature solar collector tubes in a linear concentrating solar power generation system. The system includes a flight vehicle 1 and a temperature detection device mounted on the flight vehicle, as well as a data processing device 5 wirelessly connected to the temperature detection device. The flight vehicle can be a general-purpose quadcopter drone or a specially designed hovering or stretching vehicle that operates in other ways.

[0036] The linear concentrating solar power system includes at least one array of solar collectors, consisting of multiple high-temperature solar collectors 6 arranged in an array. During testing, the flight vehicle flies over each high-temperature solar collector according to a predetermined procedure or pattern and hovers above a selected target collector, with the temperature detection device facing the target collector. During hovering, the temperature detection device detects the temperature of the glass tube 7 and the temperature of the inner metal tube 8 of the selected target collector, obtaining a first temperature value reflecting the glass tube temperature and a second temperature value reflecting the inner metal tube temperature. After obtaining the first and second temperature values, the temperature detection device transmits them to a data processing device.

[0037] The temperature detection device includes a first temperature sensor 2 for acquiring a first temperature value and a second temperature sensor 3 for acquiring a second temperature value. The first temperature sensor is an infrared thermal imager with a wavelength range of 8–14 μm, used to acquire the overall temperature of the glass tube. The second temperature sensor is a low-emissivity infrared thermometer with a wavelength range of 1–5 μm. When acquiring the second temperature value, the distance between the lens of the infrared thermometer and the high-temperature solar collector tube is controlled to be 0.1–1 m, and the temperature at the center of the inner metal tube is acquired during the acquisition process.

[0038] The data processing device is used to calculate and process the first and second temperature values ​​based on a preset algorithm to obtain the vacuum degree of the high-temperature solar collector tube. The preset algorithm can either look up the vacuum degree from a temperature-vacuum MAP based on the first and second temperature values, or it can calculate the vacuum degree based on a pre-trained neural network model. The temperature-vacuum MAP is obtained by calibrating a standard collector tube; the neural network model is obtained by measuring the standard collector tube under different temperature and vacuum conditions to obtain training samples, and then training the constructed neural network based on the training samples.

[0039] In addition, the flight vehicle in this application is also equipped with a satellite positioning module 4, which is used to provide positioning signals to the flight vehicle so that the flight vehicle can obtain position information based on the positioning signals, and collect the temperature of each collector in the collector array in sequence based on the position information and the patrol plan.

[0040] As can be seen from the above technical solution, this embodiment provides a vacuum degree detection system for solar collector tubes. This system is used to detect the vacuum degree of high-temperature solar collector tubes in a linear concentrating solar thermal power generation system in real time. Specifically, it includes a flight vehicle and a temperature detection device mounted on the flight vehicle, as well as a data processing device wirelessly connected to the temperature detection device. The flight vehicle moves within the solar collector tube array of the linear concentrating solar power generation system according to a preset pattern, and sequentially orients the temperature detection device toward the target solar collector tube. The temperature detection device collects a first temperature value of the glass tube of the target solar collector tube and a second temperature value of the inner metal tube of the target solar collector tube. The data processing device calculates the vacuum degree of the target solar collector tube based on a predetermined algorithm using the first and second temperature values. By sequentially obtaining the vacuum degree of each solar collector tube, users can identify solar collector tubes with substandard vacuum degrees and take appropriate measures, such as repair or replacement, thereby avoiding significant heat loss to the system due to a decrease in vacuum degree.

[0041] Figure 2This is a flowchart of a detection control method according to an embodiment of this application.

[0042] like Figure 2 As shown, the detection and control method of this embodiment is applied to the vacuum degree detection system of the high-temperature solar collector tube of the linear concentrating solar power generation system in the previous embodiment to detect the vacuum degree, and is used to control the vacuum degree detection system to detect the collector tube in order to obtain the vacuum degree. The detection and control method specifically includes the following steps:

[0043] S1. Select the target heat collection tubes in sequence and hover the flight vehicle above the target heat collection tubes.

[0044] This involves sequentially selecting one high-temperature solar collector from among multiple high-temperature solar collectors in the collector array, designating it as the target collector. After selecting the target collector, the flight vehicle is controlled to hover directly above it, and the lens or detection element of the temperature detection device is directed towards the target collector. Given that the temperature detection device includes an infrared thermal imager and a low-reflectivity infrared thermometer, the infrared thermal imager is directed towards the glass tube of the target collector, and the lens of the low-reflectivity infrared thermometer is directed towards the inner metal tube.

[0045] S2. Use a temperature detection device to collect the first and second temperature values ​​of the target heat collector tube.

[0046] During the specific data acquisition process, the flight vehicle is controlled to hover directly above the target heat collection tube, and the temperature of the glass tube is detected based on the infrared thermal imager to obtain a first temperature value; simultaneously or subsequently, the flight vehicle is controlled to hover directly above the target heat collection tube, and the lens of the low emissivity infrared thermometer is controlled to maintain a distance of 0.1 to 1 m from the glass tube, and the low emissivity infrared thermometer is directed towards the inner metal tube to collect the temperature, thereby obtaining a second temperature value.

[0047] S3. Process the first and second temperature values ​​to obtain the vacuum degree.

[0048] The system uses a preset algorithm to calculate the vacuum level of the target solar collector tube based on the first and second temperature values. After completing the calculation for the current collector tube, the system controls the flight vehicle to fly to the next high-temperature solar collector tube, using it as the next target collector tube for temperature acquisition and vacuum level calculation.

[0049] The preset algorithm here can either look up the vacuum level from the temperature-vacuum MAP based on the first and second temperature values, or it can calculate the vacuum level based on the first and second temperature values ​​using a pre-trained neural network model. The temperature-vacuum MAP is obtained by calibrating a standard solar collector tube; the neural network model is obtained by measuring the standard solar collector tube under different temperature and vacuum conditions to obtain training samples, and then training the constructed neural network based on these training samples.

[0050] As can be seen from the above technical solution, this embodiment provides a detection and control method applied to a solar collector tube vacuum degree detection system. Specifically, the method involves sequentially selecting the target solar collector tubes and hovering the flight vehicle above them; using a temperature detection device to collect a first temperature value and a second temperature value of the target solar collector tube; and using a preset algorithm to calculate the vacuum degree of the target solar collector tube based on the first and second temperature values. This method allows the vacuum detection system to sequentially detect the vacuum degree of high-temperature solar collector tubes, enabling users to address issues such as repair or replacement when the vacuum degree of a particular collector tube fails to meet standards, thereby preventing significant heat loss to the system due to a decrease in vacuum degree.
