Description

Technical Field

[0001] The present application relates to the field of infrared temperature measurement technology, and in particular to a temperature measurement and correction system and an unmanned aerial vehicle airport and infrared temperature measurement system comprising the same. Background Art

[0002] Uncooled infrared temperature measurement modules, for example, are often placed in drone pods for power inspections, oil and gas pipeline inspections, and industrial temperature measurement. Infrared temperature measurement modules use long-wavelength temperature measurement, and their accuracy is significantly affected by ambient temperature and humidity, as well as atmospheric attenuation. Therefore, when used on-site at end-customer locations such as power towers, oil and gas pipelines, and substations, the temperature measurement accuracy of these modules is consistently lower than the factory-provided accuracy. This makes them unable to meet high-precision temperature measurement requirements and can only be used for rough temperature measurement, limiting their application scenarios.

[0003] In order to improve the temperature measurement accuracy of the infrared temperature measurement module, an existing practice is to carry both the infrared temperature measurement module and the calibration equipment for the infrared temperature measurement module on a drone, so that the infrared temperature measurement module can be calibrated by the temperature calibration equipment at the end customer's temperature measurement site, thereby improving the temperature measurement accuracy of the infrared temperature measurement module at the temperature measurement site.

[0004] However, installing infrared temperature measurement and calibration equipment on drones increases the weight of the drone, thereby increasing its power consumption. Furthermore, the infrared temperature measurement and calibration equipment is housed within the drone's pod, occupying a significant amount of space and making it unsuitable for drones with limited pod space. Furthermore, maintaining the infrared temperature measurement and calibration equipment within the pod is inconvenient and costly.

[0005] The above description is merely the technology known to the inventor of the present application, and does not necessarily constitute the prior art of the present application simply because it appears in the background technology. Utility Model Content

[0022] The temperature measurement correction system is arranged on a drone airport for parking the drone, and is used to connect with the infrared temperature measurement module when the drone is parked at the drone airport to calibrate the temperature measurement model of the infrared temperature measurement module.

[0031] See also Figure 1 As shown, it is a structural schematic diagram of an infrared temperature measurement system including a temperature measurement correction system provided according to some embodiments of the present application. In some embodiments, the temperature measurement correction system provided by the embodiments of the present application includes a temperature reference object 21, a reference temperature sensor 22 provided on the temperature reference object 21, and a controller 23 connected to the reference temperature sensor 22. The temperature reference object 21 is provided on the drone airport 1, and the reference temperature sensor 22 is used to detect the temperature of the temperature reference object 21, obtain a reference temperature T1, and send the reference temperature T1 to the controller 23. The controller 23 is connected to the infrared temperature measurement module 4 mounted on the drone 3 parked at the drone airport 1, and is used to calibrate the temperature measurement model of the infrared temperature measurement module 4 according to the deviation between the reference temperature T1 and the test temperature T2 obtained by the infrared temperature measurement module 4 when measuring the temperature reference object 21.

[0032] When not performing flight missions, drone 3 lands and parks at drone airport 1. Furthermore, in addition to providing a parking space for drone 3, drone airport 1 can also provide battery replacement and charging for drone 3, i.e., provide automatic charging services for drone 3, or help drone 3 automatically replace batteries, thereby increasing the flight operation time of drone 3 and improving the efficiency of infrared temperature measurement performed by the infrared temperature measurement module 4 on drone 3. In some embodiments, drone airport 1 can also collect infrared temperature measurement data collected by the infrared temperature measurement module 4 on drone 3, and process and store it for user use. In addition, drone airport 1 can also provide daily maintenance and inspection services for drone 3 to keep drone 3 in good condition and improve infrared temperature measurement efficiency.

[0033] In some embodiments, the controller 23 is arranged on the drone airport 1 and is wirelessly connected to the infrared temperature measurement module 4, so that when the drone 3 is parked at the drone airport 1, the temperature measurement model in the infrared temperature measurement module 4 can be read, and the model parameters of the temperature measurement model can be modified according to the deviation between the reference temperature T1 and the test temperature T2. The modified temperature measurement model is written into the infrared temperature measurement module 4 to replace the original temperature measurement model in the infrared temperature measurement module 4 to achieve correction of the infrared temperature measurement module 4.

[0034] The calibrated infrared temperature measurement module 4 performs infrared temperature measurement on a target object during flight using the modified temperature measurement model to obtain temperature information of the target object. The target object may be, for example, a power line or oil or gas pipeline. Furthermore, the drone 3 may include a pod 31 in which the infrared temperature measurement module 4 is housed. The pod 31 is rotatable, allowing the infrared temperature measurement module 4 to collect temperature information of the target object from different viewing angles during flight.

[0035] The infrared temperature measurement module 4 specifically includes an infrared camera for collecting infrared radiation information from the target object, and a core that processes the collected infrared radiation information to generate an electrical signal representing the target object's temperature. The core is programmed with a temperature measurement model, and the infrared temperature measurement module 4 converts the collected infrared radiation information based on the temperature measurement model to obtain the target object's temperature.

[0036] The temperature measurement model can be specifically a voltage-temperature curve model, wherein the voltage-temperature curve model is a mapping relationship model between voltage and temperature, wherein the voltage in the relationship model is the voltage signal converted by the infrared temperature measurement module 4 from the collected infrared radiation information, and the temperature is the temperature corresponding to the voltage signal. Based on the temperature measurement model, the infrared temperature measurement module 4 converts the collected infrared radiation information into a corresponding voltage, and then obtains the corresponding temperature based on the voltage-temperature mapping relationship. The temperature measurement model can also be a grayscale-temperature mapping relationship model, wherein the grayscale is the pixel grayscale value in the infrared image of the target object collected by the infrared camera in the infrared temperature measurement module 4. Based on the grayscale-temperature mapping relationship model, the infrared temperature measurement module 4 obtains the temperature of the target object according to the infrared image collected by the infrared camera.

[0037] According to the temperature measurement and correction system provided in some embodiments of the present application, the temperature reference object 21 and the reference temperature sensor 22 for detecting the temperature reference object 21 are both located at the drone airport 1 end. When the drone 3 is parked at the drone airport 1, the temperature measurement model of the infrared temperature measurement module 4 carried by the drone 3 is corrected. This improves the accuracy of the drone 3 carrying the infrared temperature measurement module 4 in measuring the temperature of the target object during flight. At the same time, it does not increase the size of the drone 3, reduces the flight power consumption of the drone 3, extends the flight time of the drone 3 after a single charge, and improves the efficiency of infrared temperature measurement of the target object. In addition, by arranging the temperature reference object 21 and the reference temperature sensor 22 at the drone airport 1 end, the space requirement for the pod 31 of the drone 3 is relatively low. The infrared temperature measurement system including the temperature measurement and correction system provided in the embodiments of the present application can be adapted to different types of drones 3, and the application scenarios are not limited.

[0038] In some embodiments, the controller 23 is provided on the drone airport 1. If it is an airport controller, it is wirelessly connected to the infrared temperature measurement module 4. The controller 23 provided at the drone airport 1 can further control the landing, take-off, charging and / or maintenance and inspection of the drone 3 at the drone airport 1. Placing the entire temperature measurement and correction system at the drone airport 1 can further reduce the flight power consumption of the drone 3 and improve the temperature measurement efficiency of the infrared temperature measurement system. In other embodiments, the controller 23 can also be provided at the drone 3 end. If it is a drone controller, the reference temperature sensor 22 is wirelessly connected to the controller 23 to calibrate the infrared temperature measurement module 4 based on the deviation between the reference temperature T1 and the test temperature T2 by the controller in the drone 3.

[0039] Please continue reading Figure 1 As shown, in some embodiments, the drone airport 1 further includes a nest 11 for accommodating the drone 3 and an opening and closing protective cover 12 provided on the top of the nest 11 and arched relative to the nest 11. When the drone 3 needs to be parked in the nest 11, the airport controller of the drone airport 1 controls the opening and closing protective cover 12 to be in an open state, and the drone 3 lands on the apron in the nest 11. After the drone 3 is parked in the nest 11, the airport controller controls the opening and closing protective cover 12 to be in a closed state to protect the drone 3 from wind and rain. It should be noted that in this application, the drone 3 is provided in the nest 11, which may mean that the drone 3 is provided at the bottom of the nest 11, or it may mean that the drone 3 is provided at the top of the nest 11, or it may mean that the drone 3 is provided at other locations of the nest 11.

[0040] In some embodiments, the temperature reference object 21 is arranged on the inner wall surface of the opening and closing protective cover 12 to avoid being affected by larger environmental factors (wind and rain) under the protection of the opening and closing protective cover 12, thereby preventing rapid temperature changes and having a more stable temperature, thereby improving the calibration accuracy of the infrared temperature measurement module 4.

[0041] Please continue reading Figure 1 and Figure 2 As shown, Figure 2 : is a schematic diagram of the structure of the temperature reference object 21. A magnetic structure 221 is provided on the side of the temperature reference object 21 away from the reference temperature sensor 22, and the temperature reference object 21 is fixed to the inner wall surface of the opening and closing protective cover 12 in a magnetic manner through the magnetic structure 221. Specifically, the magnetic structure 221 can be a magnetic buckle. In other embodiments, a snap-fit structure can also be provided on the side of the temperature reference object 21 away from the reference temperature sensor 22, and the temperature reference object 21 is also fixed to the inner wall surface of the opening and closing protective cover 12 in a snap-fit manner through the snap-fit structure. The temperature reference object 21 is arranged on the inner wall surface of the opening and closing protective cover 12 by magnetic attraction or snap-fitting, has a simple structure, low preparation cost, is easy to replace and maintain, and has low maintenance cost.

[0042] In some embodiments, in order to make the temperature reference object 21 relatively uniform in temperature, so as to improve the calibration accuracy of the infrared temperature measurement module 4, the temperature reference object 21 is set at a position away from the drone airport 1 and / or the relatively high heat generating devices in the drone 3. Specifically, the setting position of the temperature reference object 21 in the drone airport 1 meets the following conditions: when the drone 3 is parked in the machine nest 11 and the opening and closing protective cover 12 is in the closed state, the temperature reference object 21 is located directly above the infrared temperature measurement module 4 and the distance from the infrared camera in the infrared temperature measurement module 4 is greater than or equal to 25 cm. Furthermore, in order to obtain a relatively stable reference temperature T1, the area of the temperature reference object 21 can be 10 cm*10 cm.

[0043] The temperature measurement and correction system provided in some embodiments of the present application is arranged at the drone airport 1, which can reduce the space occupied by the infrared temperature measurement system at the drone 3 end. At the same time, there is no need to configure an additional power supply for the temperature measurement and correction system. The structure is simple and easy to implement.

[0044] Furthermore, in some embodiments, the surface of the temperature reference object 21 close to the reference temperature sensor 22 is a temperature-uniform surface with an emissivity greater than or equal to 0.98. Specifically, the material of the temperature reference object 21 can be copper, or a layer of high-emissivity coating such as matte black paint or other blackbody material can be coated on the surface of the temperature reference object 21 away from the coupling protective cover 12. Compared with the method of using a conventional blackbody for temperature correction, the temperature measurement and correction system provided in some embodiments of the present application is less expensive. Of course, in other embodiments, the temperature reference object 21 can also be set as a blackbody based on demand.

[0045] Please continue reading Figure 1 As shown, in some embodiments, the temperature measurement and correction system further includes an environmental sensor 24 connected to the infrared temperature measurement module 4. The environmental sensor 24 is used to collect environmental information around the infrared temperature measurement module 4 after the drone 3 is parked in the machine nest 11, and send the environmental information to the infrared temperature measurement module 4, so that the infrared temperature measurement module 4 can measure the temperature of the temperature reference object 21 based on the environmental information to obtain the test temperature T2, thereby calibrating the temperature measurement model in the infrared temperature measurement module 4 to a temperature measurement model that matches the current environmental information, thereby improving the temperature measurement accuracy of the infrared temperature measurement module 4 on the target object.

[0046] Specifically, in some embodiments, the environmental sensor 24 includes an ambient temperature sensor and / or an ambient humidity sensor. The ambient temperature sensor is used to collect the ambient temperature T3 within the engine nest 11 and input the ambient temperature T3 into the temperature measurement model of the infrared temperature measurement module 4. The ambient humidity sensor is used to collect the ambient humidity h within the engine nest 11 and input the ambient humidity h into the temperature measurement model of the infrared temperature measurement module 4. The infrared temperature measurement module 4 obtains the test temperature T2 based on the ambient temperature T3, the ambient humidity h, and the temperature measurement model.

[0047] In some embodiments, an environmental sensor 24 is located at the drone airfield 1 to further reduce the flight power consumption of the drone 3 while ensuring the temperature measurement accuracy of the infrared temperature measurement module 4. Specifically, the environmental sensor 24 is located within the drone airfield 1's nest 11 and is wirelessly connected to the infrared temperature measurement module 4. In other embodiments, the environmental sensor 24 may also be located on the drone 3, which will not be further described here.

[0048] Some embodiments of the present application also provide an infrared temperature measurement system, which includes a temperature measurement and correction system and an infrared temperature measurement module 4 provided according to any embodiment of the present application. Among them, the infrared temperature measurement module 4 is mounted on the drone 3 and is used to perform infrared temperature measurement on the target object during the flight of the drone 3. The temperature measurement and correction system is provided on the drone airport 1 for parking the drone 3, and is used to connect with the infrared temperature measurement module 4 when the drone 3 is parked at the drone airport 1 to calibrate the temperature measurement model of the infrared temperature measurement module 4. The infrared temperature measurement module 4 can be, but is not limited to, a non-refrigerated infrared temperature measurement module, such as an infrared thermometer. The infrared temperature measurement system provided in the embodiment of the present application and the temperature measurement and correction system in the embodiment of the present application can achieve the same technical effect, which will not be repeated here.

[0049] See also Figure 3 As shown, it is a schematic diagram of the workflow of the infrared temperature measurement system provided in some embodiments of the present application. The working process of the infrared temperature measurement system provided in some embodiments of the present application mainly includes a calibration process before measuring the temperature of the target object and a use process after calibration, wherein the use process after calibration refers to the temperature measurement process of the target object after calibration. Taking the temperature reference object 21 as a black body as an example, the process of the temperature measurement calibration system calibrating the infrared temperature measurement module 4 mainly includes: collecting and inputting the black body temperature for calibration, checking the calibration results after calibration, and judging whether the current calibration makes the temperature measurement of the infrared temperature measurement module 4 meet the accuracy requirements based on the check results. If it meets the requirements, the ambient temperature and humidity are collected based on the temperature and humidity sensor to calibrate in real time and use the calibrated infrared temperature measurement module to measure the temperature of the target object. After use, the temperature measurement workflow ends. If it does not meet the requirements, the feedback is fed back to the drone system for decision-making to determine whether recalibration is required. If recalibration is required, the process returns to the step of collecting and inputting the black body temperature for calibration. If recalibration is not required, the temperature measurement workflow ends.

[0050] Specifically, the blackbody temperature is collected and input for calibration. The reference temperature T1 of the temperature reference object 21 is collected based on the reference temperature sensor 22. The reference temperature T1 and the test temperature T2 obtained by the infrared temperature measurement module 4 are then input into the controller 23. The controller 23 reads the temperature measurement curve (temperature measurement model) a1 of the infrared temperature measurement module 4 and adjusts the temperature measurement curve a1 to the temperature measurement curve a2 based on the deviation between the reference temperature T1 and the test temperature T2. The temperature measurement curve a2 is then written into the core of the infrared temperature measurement module 4, overwriting the temperature measurement curve a1 originally written into the core of the infrared temperature measurement module 4. This achieves the correction of the temperature measurement curve of the infrared temperature measurement module 4 from a1 to the temperature measurement curve a2, thus completing the calibration of the infrared temperature measurement module 4. The calibration result is specifically checked by inputting the ambient temperature T3 and ambient humidity h into the temperature measurement model of the infrared temperature measurement module 4 after the current calibration to re-measure the temperature of the temperature reference object 21 and obtain the calibrated test temperature T4. The specific method for judging whether the accuracy requirements are met is as follows: compare the test temperature T4 after calibration with the test temperature T2 before calibration to determine whether the error between T4 and T1 is less than or equal to the error threshold (such as 1°C). If it is less than or equal to the error threshold, it means that the current temperature measurement accuracy of the infrared temperature measurement module 4 meets the requirements, that is, the current calibration of the infrared temperature measurement module 4 is successful, and then the infrared temperature measurement module 4 is calibrated and used in real time based on the ambient temperature and humidity (ambient temperature and ambient humidity) until the infrared temperature measurement process is completed; if it is greater than the error threshold, it means that the current calibration has failed, and the result is fed back to the drone system for decision-making, so that the drone system can determine whether the infrared temperature measurement module 4 needs to be recalibrated.

[0051] In addition, some embodiments of the present application further provide a drone airport including a temperature measurement and correction system according to any embodiment of the present application. The drone airport provided in the embodiments of the present application and the temperature measurement and correction system provided in the embodiments of the present application can achieve the same technical effects, and will not be repeated here.

[0052] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
