Description

Technical Field

[0001] This utility model relates to the field of low-altitude industrial test chamber technology, specifically a testing device for a low-altitude industrial test chamber. Background Art

[0002] Low-altitude industrial test chambers can simulate various real low-altitude environments to test the flight performance of drones or small aircraft, thereby providing data support for the research and development and testing of low-altitude equipment.

[0003] The low-altitude industry test chamber is equipped with various devices for testing low-altitude equipment in different environments. These include environmental parameter detection devices (temperature sensors, humidity sensors, or wind speed and direction indicators), aircraft performance testing devices (accelerometers, gyroscopes, and magnetometers), aircraft optical motion capture and detection devices (high-speed cameras), and low-altitude equipment performance testing devices (vector network analyzers, bit error rate testers, or radar cross-section (RCS) measurement equipment and detector response testing systems). Among these, a high-speed camera, using computer vision technology, tracks and analyzes marker points on the aircraft to obtain its position and attitude. While the test chamber simulates different low-altitude environments, resulting in variations in temperature and humidity, high humidity can cause fogging on the high-speed camera lens, affecting its image quality. Conventional defogging methods, such as heating the lens to reduce local temperature, can also affect the simulated ambient temperature inside the test chamber. Wiping with a wiping roller can interfere with the lens's shooting, reducing the comprehensiveness of the images captured during low-altitude equipment performance testing and impacting subsequent image analysis.

[0004] Therefore, there is an urgent need for a testing device for low-altitude industrial test chambers to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] Please see Figures 1-5 The diagram shows a testing device for a low-altitude industrial test chamber, which includes a chamber 101 and a camera 102 disposed on the chamber 101. A lens 103 is provided on one side of the camera 102, and an anti-fog component disposed on the camera 102 for preventing the lens 103 from fogging in a high humidity simulated environment.

[0023] The anti-fog assembly includes a protective tube 201 fixedly connected to the side of the camera 102 near the lens 103. The protective tube 201 is sealed on the side near the camera 102 and has a first through hole 204. The lens 103 is fitted into the first through hole 204. A rotating ring 202 is rotatably connected to the side wall of the protective tube 201. The rotating ring 202 is provided with an anti-fog sheet 203. The camera 102 is provided with a driving assembly for driving the anti-fog sheet 203. A cover plate 205 is connected to the side of the protective tube 201 away from the camera 102 by multiple screws. The cover plate 205 has a second through hole 206, which is matched with the lens 103. The cover plate 205 is provided with a cleaning assembly for cleaning the anti-fog sheet 203.

[0024] It should be noted that: by setting up the anti-fog component, with the cooperation of the cleaning component and the driving component, the anti-fog sheet 203 can be rotated and used cyclically, and cleaning can be carried out during the rotation cycle. While achieving the anti-fog effect on the lens 103, compared with the existing defogging method, it can reduce the impact on the simulated environment inside the housing 101 and the shooting interference of the lens 103, thereby improving the comprehensiveness of the camera 102 in shooting during the low-altitude equipment performance test, and thus ensuring the accuracy of subsequent image analysis.

[0025] It is worth noting that the low-altitude industrial test chamber and its various internal testing devices are existing technologies, and their specific structures and working principles have been mastered by those in the field, so they will not be elaborated on here.

[0026] Please see Figure 5 The cleaning assembly shown in the figure includes multiple sponge plates 3, each sponge plate 3 is disposed on the side of the cover plate 205 near the anti-fog sheet 203, the cover plate 205 is provided with a squeezing assembly for squeezing the sponge plate 3, and the protective tube 201 is provided with a collection assembly for collecting the mist water cleaned off the sponge plate 3.

[0027] It should be noted here that the cleaning component is used to clean the fog accumulated on the surface of the anti-fog sheet 203.

[0028] It should be emphasized that the anti-fog sheet 203 is supported by ceramic material and contains titanium dioxide.

[0029] Please see Figure 5 The extrusion assembly shown in the figure includes multiple extrusion tubes 401 fixedly connected to the side of the cover plate 205 near the anti-fog sheet 203. Each extrusion tube 401 is slidably connected to an extrusion rod 402. One end of each extrusion rod 402 is connected to the sponge plate 3. A spring 403 is sleeved on the side wall of each extrusion tube 401. Both ends of each spring 403 are connected to the cover plate 205 and the sponge plate 3, respectively.

[0030] It should be noted here that the extrusion assembly is designed to ensure that the sponge plate 3 and the surface of the anti-fog sheet 203 are in contact.

[0031] Please see Figure 4 The drive assembly shown in the figure includes a fixed plate 501 fixedly connected to the lower side wall of the camera 102. The fixed plate 501 is connected to a gear 503 via a rotating shaft 502. A gear ring 504 is connected to the side wall of the rotating ring 202. The gear ring 504 and the gear 503 are meshed with each other. A motor 505 is provided on the side of the fixed plate 501 away from the gear 503. The motor 505 is a low-power motor. The output end of the motor 505 is connected to the rotating shaft 502.

[0032] It should be noted here that the drive component is configured to rotate the anti-fog sheet 203, thereby enabling the anti-fog sheet 203 to rotate cyclically and be cleaned during the rotation cycle.

[0033] Working principle: When testing low-altitude equipment, first, the aircraft or low-altitude equipment to be tested is correctly placed in the designated position inside the housing 101, and the battery and data transmission line are connected to ensure that the UAV can start normally and receive control commands. Then, various sensors used for testing (such as temperature sensors, wind speed and direction sensors, electromagnetic sensors, etc.) are installed and calibrated. Finally, the connections between the various subsystems of the test chamber (such as the environmental simulation system, data acquisition system, monitoring system, etc.) are checked to ensure that the data can be transmitted normally and that the various systems can work together. For example, check whether the communication lines between the controller of the environmental simulation system and the temperature and humidity control devices are unobstructed, and whether the data acquisition system can correctly receive the data from the sensors.

[0034] After completing the preparatory work before the test, set the simulated environmental parameters in the control system of the test chamber according to the test requirements, including meteorological parameters (such as temperature, humidity, wind speed, wind direction, etc.) and electromagnetic parameters (such as the frequency, intensity, waveform, etc. of electromagnetic signals). For example, if you want to simulate a rainy day with electromagnetic interference in a low-altitude environment, set the humidity to a high value (such as 80%-90%), and at the same time set the electromagnetic signal generator to generate interference signals of a certain intensity and frequency. Then start the aircraft or low-altitude equipment to be tested and make it run in the simulated low-altitude environment. During the start-up process, pay close attention to the start-up status of the equipment, such as whether the aircraft motor starts normally and whether the low-altitude equipment passes the self-test. For example, after starting the drone, observe whether its propeller rotates smoothly, whether the flight control system initializes normally, and whether the communication link is established.

[0035] During the experiment, the environmental data and performance data of the test object inside the test chamber are collected in real time through the data acquisition system. At the same time, the test process is monitored in real time using a monitoring system (such as high-speed camera 102, monitoring software, etc.). For example, the data acquisition system continuously collects data such as temperature, humidity, wind speed, and aircraft attitude and transmits them to the data processing unit; the high-speed camera 102 captures the flight process of the aircraft to observe whether its flight attitude and trajectory are normal.

[0036] After completing the predetermined test tasks, the operation of the test object (aircraft or low-altitude equipment) is stopped first, then the environmental simulation system of the test chamber is shut down, and finally the collected data is sorted and analyzed. The relevant performance indicators are calculated according to the test objectives, and then the test object is evaluated based on the data analysis results to determine whether it meets the design requirements or test expectations, thus completing the test and inspection of the low-altitude equipment.

[0037] Furthermore, during the testing of low-altitude equipment, when a high-humidity environment is simulated inside the housing 101, the motor 505 can be started to drive the gear 503 on the rotating shaft 502 to rotate. Under the mutual meshing transmission of the gear 503 and the gear ring 504, the anti-fog sheet 203 on the rotating ring 202 will rotate. During the rotation of the anti-fog sheet 203, the squeezing component pushes the sponge plate 3 to clean the anti-fog sheet 203. Thus, through the cyclical use of the anti-fog sheet 203 and the cleaning during the cyclical rotation, the accumulation of fog on the surface of the anti-fog sheet 203 is reduced, thereby reducing the impact of the high-humidity simulated environment on the shooting of the lens 103. Compared with the existing defogging method, it can reduce the impact on the simulated environment inside the housing 101 and the interference with the shooting of the lens 103. Thus, while achieving the anti-fog effect on the lens 103, it improves the comprehensiveness of the shooting during the performance testing of the low-altitude equipment, thereby ensuring the accuracy of subsequent image analysis.

[0038] Example 2

[0039] Please see Figure 4 This embodiment further illustrates Example 1. The collection component shown in the figure includes a collection box 601 that is detachably disposed on the side of the protective tube 201 near the motor 505. A collection hole 602 is provided on the side of the protective tube 201 near the collection box 601.

[0040] It should be noted that the collection component is designed so that when the amount of mist is large during the scraping and cleaning process of the anti-fog sheet 203 by the sponge plate 3, it can flow into the collection box 601 through the collection hole 602, thereby achieving centralized collection of mist and preventing the mist from flowing freely and causing the anti-fog sheet 203 to become wet again.

[0041] Please see Figure 4The collection hole 602 in the figure is equipped with a one-way valve, and the one-way valve is directed from the inside of the protective tube 201 to the inside of the collection box 601.

[0042] It should be noted here that by setting up a one-way valve and limiting the direction of the one-way valve's conduction, the backflow of the mist collected in the collection box 601 into the protective pipe 201 can be prevented.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
