Description

Technical Field

[0001] This invention relates to the field of temperature measurement technology, and in particular to a temperature measurement device and method based on fluorescent materials. Background Technology

[0002] Temperature measurement technology is a technique that uses various physical and chemical principles and methods to measure the temperature of objects and the environment.

[0003] Among many temperature measurement technologies, fluorescent materials can be used as an effective temperature sensor because they emit fluorescence when excited by a specific light source, and their fluorescence characteristics change with temperature.

[0004] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: Existing fluorescent temperature measuring devices have certain limitations in terms of measurement accuracy and resolution. Due to the instability of the light source and environmental interference, they are difficult to meet the requirements of high-precision temperature measurement. Furthermore, the fluorescence properties of some fluorescent materials gradually degrade during use, affecting the stability and reliability of the temperature measuring device and increasing the cost and workload of replacing materials.

[0005] Many existing fluorescent materials contain harmful substances such as lead and cadmium, which can easily pollute the environment during use and also pose potential hazards to human health.

[0006] Furthermore, traditional fluorescence thermometers are often large, complex, and inconvenient to carry, making it difficult to meet the diverse temperature measurement needs in different scenarios. In addition, traditional devices have limited expandability and are difficult to connect and exchange data with other devices, which limits their application scope. Summary of the Invention

[0007] This application provides a temperature measuring device and method based on fluorescent materials, which solves the technical defects of the prior art, such as insufficient temperature measurement accuracy and resolution, short service life of fluorescent materials, and the fact that fluorescent materials often contain toxic, harmful, or environmentally polluting substances, as well as the need to improve the integration and expansion capabilities of temperature measuring devices. It improves the accuracy and resolution of temperature measurement technology, extends the service life of fluorescent materials, and uses non-toxic and non-polluting fluorescent materials, reducing harm to the human body and the environment. In addition, it improves the integration and expansion capabilities of temperature measuring devices, enabling the devices to be presented in a more portable form and to be connected to other devices for device updates and functional expansion.

[0008] This application provides a temperature measuring device based on fluorescent materials, including: The outer shell is a hollow structure used to provide space for the components of the entire testing device, including: an upper cover and an outer shell base, used to load and realize all the components of the device; LED light source, wherein the LED light source is an ultraviolet LED lamp bead, which is set on the housing base and is used to excite the fluorescent material to make the fluorescent material emit light; A fluorescent material, wherein the fluorescent material is disposed in the light emission path of the LED light source and is excited to light after being irradiated by the LED light source; The fiber optic probe, housed within the housing base, is connected to the fluorescent material and is used to detect various parameters of the light emitted by the fluorescent material when it is excited. The fiber optic spectrometer, housed within the base casing and connected to the fiber optic probe, is used to receive various parameters of the light detected by the fiber optic probe. The optical fiber, housed within the housing base, is used to connect the optical fiber probe and the optical fiber spectrometer, transmitting signals between the two. The control console, located inside the housing base, stores a database of various optical parameter combinations and their corresponding temperatures. It is connected to the fiber optic spectrometer assembly via a ribbon cable and is used to receive signals from the fiber optic spectrometer and output temperature values. In addition, it is used to control the issuance of operating commands for all components of the entire device. The display screen, located inside the housing base, is used to receive temperature values ​​output from the console and feed them back to the user. In addition, it can also receive commands from the user and perform corresponding operations. By integrating various components into the housing, this device can achieve temperature measurement while reducing the space occupied by the temperature measurement device, making the temperature measurement equipment smaller, more portable, and more convenient to use. Furthermore, the top cover has holes on its surface, the positions of which correspond to the display screen inside the outer casing base, enabling the device described in this application to achieve human-computer interaction without opening the top cover, reducing the contact time between the internal components of the device and the outside world, reducing the impact of the external environment on the device, and extending the service life of the device. Furthermore, the console can interact with other devices via wired or wireless connections. By connecting to external devices, the device can be updated and its functions expanded, thus improving the scalability of the temperature measuring device. Furthermore, the fluorescent material is specifically CsSnBr3. By using Sn to replace Pb, which is commonly used in the prior art, the toxic, harmful and environmentally polluting substances in the fluorescent material are removed, making the fluorescent material used in this application non-toxic, harmless and pollution-free, safer, and protecting the safety of users and the environment. Furthermore, the fluorescent material is disposed within a support structure, which is a slot-type thin-film fixing seat. The fluorescent material supported by the support structure is located on the direct path of the LED light source and within the detection range of the fiber optic probe. By fixing the fluorescent material in a semi-enclosed manner, it is convenient to replace the fluorescent material while avoiding displacement of the fluorescent material that could cause detection errors. This achieves accurate temperature detection and reduces wear on the fluorescent material.

[0009] Furthermore, this application also provides a temperature measurement method based on fluorescent materials, applicable to any of the aforementioned temperature measurement devices based on fluorescent materials, specifically including the following steps: S0: Database input. The console accepts and stores the "light parameters - temperature" database input by the user. S1: Excitation fluorescent material. At the temperature to be measured, the control console controls the LED light source to excite the fluorescent material CsSnBr3. S2: Light sample acquisition. At the temperature to be measured, the control console controls the fiber optic probe to acquire a light sample. The light sample comes from the light emitted by the fluorescent material after it is excited. S3: Optical composition analysis. The control console controls the fiber optic spectrometer to receive optical samples collected from the fiber optic probe via optical fiber, and to analyze and detect the optical samples. S4: Optical parameter transfer, the console retrieves the optical parameters obtained after analyzing and detecting the optical sample in the fiber optic spectrometer; S5: Temperature value determination. The control console compares the optical parameters with the stored "optical parameters-temperature" database and determines the specific temperature data to be measured based on the optical parameters. S6: Temperature feedback value. The console transmits the specific temperature data to the display screen, which then displays the specific temperature data back to the user.

[0010] By using an LED light source to excite CsSnBr3 at the temperature to be measured, and then using a fiber optic probe and fiber optic spectrometer to obtain the light parameters emitted by the fluorescent material at the current temperature, the measured temperature value is obtained by comparing it with the "light parameter-temperature" database stored in the control console, and the value is fed back to the user. The CsSnBr3 material used replaces the traditional fluorescent material CsPbBr3, eliminating the participation of Pb, making the temperature measurement method safer and harmless. Furthermore, by comparing the database with the actual light parameters, a more accurate temperature value can be obtained, improving the accuracy of the temperature measurement method. All components used in the entire temperature measurement process are inside the housing, and the temperature measurement method only requires the temperature measurement device to achieve the temperature measurement function, making the temperature measurement operation more convenient and efficient. Furthermore, in step S0, the user can input the database by interacting with the console through the display screen, or by directly connecting to the console via wired or wireless means. Furthermore, steps S1 to S6 are necessary procedures for each temperature detection method, and step S0 is a necessary step before the first temperature detection. When any version of the "light parameter-temperature" database is stored in the control console, the comparison operation described in step S5 can be performed to obtain the specific temperature data of the temperature to be measured. Step S0 can be used to update the database whenever any "light parameter-temperature" database is updated in order to obtain the latest and most accurate specific temperature data of the temperature to be measured, thereby improving the accuracy and resolution of the temperature measurement method. Furthermore, in step S3, the analysis and detection of the light sample specifically involves: analyzing and detecting to obtain spectral ratio data, color temperature data, and color coordinate data; and by detecting multiple light parameters, when comparing the light parameters with the "light parameter-temperature" database, comparisons can be made with any different light parameters and temperatures, thereby improving the accuracy and resolution of the specific temperature data to be measured. Furthermore, in step S5, when performing the comparison, any one, two, or three optical parameters from the spectral ratio data, color temperature data, and color coordinate data can be used for comparison in the database to determine the specific temperature data of the temperature to be measured. Comparison with any optical parameter and temperature value is allowed. When the number of optical parameters used for comparison is greater than one, the final output temperature is the average value. That is, S5 is subdivided into: S5': Initial data comparison. The console compares each optical parameter with the stored "optical parameter-temperature" database and determines the corresponding temperature data based on each optical parameter. S5'': Comparison result processing, calculate the average value of the corresponding temperature data obtained from each optical parameter, and the average value is the specific temperature data of the temperature to be measured; When optical parameters and temperature data correspond to a single value, the accuracy of the temperature measurement results can be improved; when optical parameters and temperature data correspond to a value and a range of values, the resolution of the temperature measurement results can be improved.

[0011] Furthermore, the method for determining the specific temperature data to be measured in step S5 involves matching the detected data with a preset parameter model (spectral ratio-color temperature-color coordinates-temperature) in the database, and calculating the ambient temperature using a neural network algorithm. This neural network algorithm fully utilizes the complex correlation between the detected data and the preset parameter model to more accurately analyze the ambient temperature. The temperature determined in this way is not only highly accurate but also more adaptable to complex and changing environments. Even if there are slight changes in light parameters such as spectral ratio, color temperature, and color coordinates in the environment, the neural network algorithm can sensitively capture these changes and, through its complex calculation model, transform them into accurate temperature data.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. By using the fluorescent material CsSnBr3, the problem of existing fluorescent materials containing toxic and harmful substances is effectively solved, achieving non-toxic, harmless, and pollution-free results, protecting the safety of users and the environment; at the same time, the fluorescent material CsSnBr3 has good stability and a long service life, solving the problem of short service life of fluorescent materials and reducing the cost and workload of replacing materials.

[0013] 2. Due to the adoption of integrated design, by integrating components such as LED light source, fiber optic probe, fiber optic spectrometer, and control console into the housing, the problem of large size and inconvenience of traditional fluorescence temperature measurement equipment is solved, and the integration and portability of the equipment are improved.

[0014] 3. By adopting a wired connection between the control console and external devices, data interaction with other devices is achieved, effectively solving the problem of limited expandability of temperature measuring equipment.

[0015] 4. By utilizing the "light parameter-temperature" database and neural network algorithm within the control panel, the issues of insufficient temperature measurement accuracy and resolution are resolved. The database provides a precise correspondence between light parameters and temperature, while the neural network algorithm matches the detected light parameters with the database to obtain more accurate temperature data.
