[0002] In the entire production cycle of aircraft design, pre-research, and mass production, quality control at key nodes is an important link to ensure the safety and reliability of products. Among them, during the research and development stage, quality inspection often uses non-explosive joint training products as the equivalent of formal products to conduct preliminary tests on aircraft functions, environments, etc. The environmental test of the joint training products mainly involves the centralized cooperation of four teams: aircraft loading, test bench control, test data monitoring, and aircraft state testing, and the test work is carried out around the mechanical properties of the aircraft such as three-axis impact, vibration, and centrifugation. In such a dense working condition of personnel and equipment, there are often malignant characteristics such as high noise, poor layout, and messy environment. High noise is likely to cause tinnitus or even deafness in staff, seriously affecting physical health. The messy environment and poor layout result in a high-dust environment, which makes it easy for dirt to adhere to the surface of aviation connectors.

The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0069] As Figures 1 to 18 shown, according to an embodiment of the present disclosure, a safety protection system 100 for the test working condition of an aircraft is proposed, including: a housing 110, an accommodation cavity is formed inside the housing 110; a wiping part 120, connected to the housing 110 and located at the side of the housing 110, the wiping part 120 is used for wiping the surface to be cleaned of an aviation connector, the wiping part 120 is provided with a porous structure 1211, and the wiping part 120 communicates with the accommodation cavity through the porous structure 1211; a humidifying part 130, covering the wiping part 120 and used for providing a cleaning liquid to the wiping part 120; a fan 140, fixedly installed in the accommodation cavity through a positioning part 160, an air suction port 141 of the fan 140 faces the wiping part 120, and the fan 140 is used for generating a negative pressure air flow to suck the dirt on the surface to be cleaned of the aviation connector into the fan 140; wherein, the positioning part 160 is provided with a discharge structure, an air discharge port of the fan 140 communicates with the discharge structure, and the discharge structure is used for discharging the dirt sucked into the fan 140; a noise filtering communication part 150, arranged on the side of the housing 110, the noise filtering communication part 150 includes an earplug 152 and a noise filtering transmission unit, wherein, the noise filtering transmission unit is used for receiving and filtering audio data to retain the low-frequency voice segment data in the audio data and sending the low-frequency voice segment data to the earplug 152.

[0070] It can be understood that the safety protection system 100 for the flight vehicle test working condition test process provided by the embodiments of the present disclosure is provided with a housing 110, a wiping part 120, a humidifying part 130, a fan 140, a positioning part 160, and a noise filtering communication part 150. Among them, a placement cavity is formed inside the housing 110. The wiping part 120 is connected to the housing 110 and is located on the side of the housing 110. The wiping part 120 wipes the surface to be cleaned of the aviation connector to remove dirt. Further, the wiping part 120 is provided with a porous structure 1211. The wiping part 120 communicates with the placement cavity through the porous structure 1211. The humidifying part 130 covers the wiping part 120. Before wiping the surface to be cleaned, the cleaning liquid can be provided to the wiping part 120 through the humidifying part 130. After humidification is completed, the humidifying part 130 is removed, and the dirt can be more easily cleaned with the cleaning liquid. The fan 140 is fixedly installed in the placement cavity through the positioning part 160. The air suction port 141 of the fan 140 faces the wiping part 120. The fan 140 can generate a negative pressure air flow, and the positioning part 160 is provided with a discharge structure. The air discharge port of the fan 140 communicates with the discharge structure. With such a setting, when wiping the surface to be cleaned of the aviation connector, while the wiping part 120 soaked with the cleaning liquid wipes off the dirt, the dirt is sucked into the housing 110 by the negative pressure generated by the fan 140 and can be discharged through the discharge structure, avoiding the situation in the related art that only the wiping action pushes the dirt into the slot holes of the aviation connector and causes blockage. At the same time, the rotation operation between the dirt suction operation and the wiping operation is also saved. And the integrated humidifying part 130 does not need to spray the cleaning liquid on the surface to be cleaned while wiping, which is convenient to operate, improves the cleaning efficiency, and improves the safety protection of the aviation connector. At the same time, the safety protection system is integrated with a noise filtering communication part 150. Specifically, the noise filtering communication part 150 is arranged on the side of the housing 110. The noise filtering communication part 150 is provided with earplugs 152 and a noise filtering transmission unit. Among them, the audio data of the on-site environment can be received and filtered through the noise filtering transmission unit, and the low-frequency audio segment data of the human voice in the audio data is retained, and the low-frequency audio segment data of the human voice is sent to the earplugs 152 for on-site staff to communicate, ensuring normal communication. At the same time, the interference of environmental noise on the communication signal and the impact on the physical and mental health of the staff are reduced, the noise pollution is reduced, and the safety protection of the staff is realized. Exemplarily, the cleaning liquid can be selected according to the actual on-site requirements, such as alcohol.

[0071] Exemplarily, such as Figure 3 shown, an installation groove 190 is formed on the side of the positioning part 160.

Such as Figure 5As shown, the noise filtering and transmission unit may select the interconnected noise filtering main board 151, which is installed on the back of the placement box 153. The interconnected noise filtering main board 151 is integrated with a radio module, a noise filtering module, a multi-device wireless data transmission module, and a main board earplug 152 data transmission module. With such a setting, communication is carried out through the radio module. The noise filtering module only retains the low-frequency voice segment data in the signal-noise mixed data through frequency selection. The filtered low-frequency voice segment data is sent to other interconnected noise filtering main boards 151 through the multi-device wireless data transmission module and received. The low-frequency voice segment data is sent from the interconnected noise filtering main board 151 to the earplug 152 through the main board earplug 152 data transmission module, so that the staff wearing the earplug 152 can receive it. Thus, while reducing the on-site noise heard by the staff, clear conversations can be achieved, reducing the interference of environmental noise on communication signals and the physical and mental impact on the staff, reducing noise pollution, and achieving safety protection for the staff.

Among them, the speaker installation section 1522 is close to the front end of the plug body 1521, and the size of the intermediate section 1523 is smaller than the inner diameter size of the speaker installation section 1522. The outer diameter size of the front end of the plug body 1521 is smaller than the outer diameter of the tail. The communication component is provided with an electroacoustic transducer 1525, a wire 1526, a receiving board 1527, and a power supply battery 1528. Among them, the electroacoustic transducer 1525 is installed in the speaker installation section 1522, the wire 1526 is arranged in the hard tube of the intermediate section 1523, and both the receiving board 1527 and the power supply battery 1528 are arranged in the tail installation section 1524. The receiving board 1527 is electrically connected to the electroacoustic transducer 1525 through the wire 1526, and the earplug 152 is powered by the communication battery. So that the received low-frequency voice segment data electrical signal is converted into a sound wave signal by the receiving board 1527, so that the staff wearing the earplug 152 can clearly hear the voice.
