[0002] Currently, target equipment that requires a specific gas environment is typically placed in an equipment cabin. Maintaining the required gas environment within the cabin ensures normal operation of the target equipment. Therefore, the equipment cabin is used as a test cabin, where the gas environment is monitored.

[0003] Monitoring the gas within the test chamber is often accomplished using multiple sensors. The test chamber requires ventilation ports connected to each sensor to allow gas to circulate between the sensors and the chamber. To ensure that each sensor can communicate with the test chamber, the number of ventilation ports required to connect to the sensor must increase as the number of sensors increases. This can lead to an excessive number of ventilation ports, compromising the chamber's sealing performance and creating a risk of leakage.

[0004] Therefore, how to monitor the gas in the test chamber while maintaining better sealing performance is a technical problem that those skilled in the art need to solve urgently. Utility Model Content

[0026] Optionally, a portion of the electromagnetic shielding shell is formed as a partition plate, which separates the electrical control cavity from the gas channel cavity;

[0027] Among them, each sensor probe in the gas channel cavity is installed on the partition plate and is electrically connected to the control circuit board through the second signal line; the second sensing end is connected to the electrical control cavity to connect to the external gas through the electrical control cavity.

[0045] To enable those skilled in the art to better understand the technical solutions of this application, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of this application.

[0046] See also Figure 1 The environmental monitoring system 10 of the present application includes a test chamber 100 , an environmental monitoring device 200 and a host computer 300 .

[0047] The test chamber 100 is used to accommodate the target device ( Figures 1 to 4(not shown), the target device is a device that needs to work in a specific gas environment. The environmental monitoring device 200 is arranged outside the test cabin 100, so as to avoid or reduce the impact of the environmental monitoring device 200 on the operation of the target device in the test cabin 100 when it is working. The environmental monitoring device 200 is connected to the test cabin 100 to monitor the gas in the test cabin 100 to form corresponding monitoring data. The host computer 300 is arranged outside the test cabin 100, so as to avoid or reduce the impact of the host computer 300 on the operation of the target device in the test cabin 100 when it is working. The host computer 300 is electrically connected to the environmental monitoring device 200 to receive the monitoring data output by the environmental monitoring device 200.

[0048] Specifically, combined Figure 1 See Figure 2-Figure 4 The test chamber 100 has a first ventilation interface 101 and a second ventilation interface 102 , and the environment monitoring device 200 includes an electromagnetic shielding shell 210 , a control circuit board 220 and a plurality of sensor probes 230 .

[0049] The electromagnetic shielding shell 210 is internally formed with an electrical control chamber 211 and a gas passage chamber 212, which are separated from each other. The gas passage chamber 212 is connected to the test chamber 100 through the first ventilation interface 101 and the second ventilation interface 102. The gas passage chamber 212 is used for the gas in the test chamber 100 to flow through. The gas flow path in the gas passage chamber is as follows: Figure 3 As shown by the dashed arrow in the figure, a control circuit board 220 is disposed in the electrical control chamber 211. Multiple sensing probes 230 are disposed in the gas passage chamber 212 and are electrically connected to the control circuit board 220 for monitoring the gas within the test chamber 100. The control circuit board 220 generates corresponding monitoring data based on the monitoring results of the sensing probes 230.

[0050] Through the above-mentioned manner, the present application has at least the first to third effects.

[0051] First, the electromagnetic shielding case 210 can shield or suppress electromagnetic signals. This prevents or suppresses electromagnetic signals generated by other external devices from interfering with the sensor probe 230 and control circuit board 220 within the electromagnetic shielding case 210. Furthermore, when the control circuit board 220 and sensor probe 230 are operating within the electromagnetic shielding case 210, electromagnetic signals generated by the control circuit board 220 can be prevented from interfering with the sensor probe 230, and vice versa.

[0052] The second effect is that the sealing performance of the test chamber 100 can be improved from the third and fourth aspects, so that the gas in the test chamber 100 can be monitored while maintaining a better sealing performance of the test chamber 100.

[0053] Thirdly, by monitoring the gas flowing into the gas passage cavity 212, multiple sensor probes 230 can achieve the purpose of monitoring the gas in the test chamber 100. Therefore, the test chamber 100 only needs to be provided with a ventilation interface connected to the gas passage cavity 212, without having to provide a separate ventilation interface for each sensor probe 230. Therefore, the number of ventilation interfaces required to be provided in the test chamber 100 is reduced, which can improve the sealing performance of the test chamber 100. Fourthly, the electrical control cavity 211 is separated from the gas passage cavity 212, so that the external gas in the electrical control cavity 211 will not or will hardly flow into the gas passage cavity 212, thereby improving the sealing performance of the test chamber 100.

[0054] In one example, the environmental monitoring device 200 can be installed on the outer wall of the test chamber 100, so that the gas in the test chamber 100 can flow into the gas passage cavity 212, but the present invention is not limited thereto. In another example, the environmental monitoring device 200 can be separated from the outer wall of the test chamber 100 and installed elsewhere.

[0055] Optionally, refer to Figure 2-Figure 4 As shown, the target device can be a laser device ( Figures 1-4 (Not shown) The gas in the test chamber 100 may include air. Since the proper operation of the laser device is related to the humidity, dust particle content, and organic matter content of the air in the test chamber 100, three of the multiple sensor probes 230 may be a humidity probe 231, a particle counter 232, and an organic matter probe 233.

[0056] The humidity probe 231 is used to measure the humidity of the air in the test chamber 100; the particle counter 232 is used to measure the content of dust particles in the air in the test chamber 100; and the organic matter probe 233 is used to measure the content of organic matter in the air in the test chamber 100.

[0057] Optionally, combined Figure 1 like Figure 2-Figure 4 As shown, the laser beam generated by the laser device, during its emission from the test chamber 100 to the outside, can be stably emitted depending on the pressure difference between the air inside the test chamber 100 and the outside air. Furthermore, the proper operation of the laser device is also dependent on the oxygen concentration in the air inside the test chamber 100. Therefore, two of the multiple sensor probes 230 are a pressure differential probe 234 and an oxygen concentration probe 235.

[0058] The differential pressure probe 234 has a first sensing end and a second sensing end. The first sensing end is connected to the gas passage cavity 212, and the second sensing end is connected to the outside air. The differential pressure probe 234 is used to measure the pressure difference between the air in the test chamber 100 and the outside air. The oxygen concentration probe 235 is used to measure the oxygen concentration in the air in the test chamber 100.

[0059] Optionally, combined Figure 1 See Figure 2-Figure 4 As shown, since the normal operation of the laser device is related to the air pressure and temperature of the air in the test chamber 100, two of the multiple sensor probes 230 are a pressure probe 236 and a temperature probe 237. The pressure probe 236 is used to measure the air pressure in the test chamber 100, and the temperature probe 237 is used to measure the air temperature in the test chamber 100.

[0060] Further, combined with Figure 1 See Figure 2-Figure 4 As shown, the environment monitoring system 10 includes a first signal line 400 , and the environment monitoring device 200 includes an air inlet interface 201 , an air return interface 202 , and an electrical interface 203 .

[0061] The air inlet interface 201 connects the gas passage cavity 212 and the first ventilation interface 101, respectively, and is used to pass the gas in the test chamber 100 into the gas passage cavity 212. The air return interface 202 connects the gas passage cavity 212 and the second ventilation interface 102, respectively, and is used to allow the gas entering the gas passage cavity 212 to flow back into the test chamber 100 from the gas passage cavity 212. The electrical interface 203 communicates with the electrical control cavity 211, and the first signal line 400 passes through the electrical interface 203 and is electrically connected to the control circuit board 220 and the host computer 300.

[0062] In one example, electrical control chamber 211 can exchange air with the outside air through electrical interface 203, but this is not limited to this. In another example, electrical control chamber 211 can exchange air with the outside air through other vents (not shown). It should be noted that the outside air can refer to air outside the environmental monitoring device 200 and outside the electromagnetic shielding shell 210.

[0063] Optionally, combined Figure 1 See Figure 2-Figure 4 As shown, the plurality of sensing probes 230 can be arranged in at least one queue. The queue includes, but is not limited to, a plurality of sensing probes 230 arranged sequentially along the air flow path within the gas passage cavity 212. This arrangement can more fully utilize the space within the gas passage cavity 212 and avoid or reduce electromagnetic interference between the sensing probes 230.

[0064] Optionally, combined Figure 1 See Figure 2-Figure 4As shown, the multiple sensor probes 230 are arranged into a first and second adjacent rows. The sensor probes 230 in the first and second rows are alternately distributed along the gas flow path within the gas passage cavity 212. The sensor probes 230 in the first row are staggered with the sensor probes 230 in the second row in a direction perpendicular to the gas flow path within the gas passage cavity 212, but the arrangement is not limited thereto. This allows for better utilization of the space within the gas passage cavity 212.

[0065] Optionally, the first array of sensor probes 230 may be, but are not limited to, pressure probes 236, organic matter probes 233, and humidity probes 231. The second array of sensor probes 230 may be, but are not limited to, temperature probes 237, differential pressure probes 234, and oxygen concentration probes 235.

[0066] It should be noted that, in other examples, the multiple sensing probes 230 in the gas channel cavity 212 may also be distributed in a scattered manner, concentrated manner, or in other arrangements, as long as the sensing probes 230 can each achieve the air detection effect.

[0067] Optionally, combined Figure 1 See Figure 2-Figure 4 As shown, a portion of the electromagnetic shielding shell 210 is formed into a partition plate 213, which separates the electrical control chamber 211 from the gas passage chamber 212. Each sensing probe 230 within the gas passage chamber 212 is mounted on the partition plate 213, and each sensing probe 230 is electrically connected to the control circuit board 220 via a second signal line (not shown). The second sensing end communicates with the electrical control chamber 211 to allow for communication with the outside air through the electrical control chamber 211. This allows the sensing probes 230 to be distributed in a more centralized manner, further miniaturizing the environmental monitoring device 200.

[0068] Combine Figures 1-4 , see Figure 5 As shown, the aircraft 500 of the present application includes an aircraft body 510 and a laser device 520 .

[0069] The aircraft body 510 may be an aircraft or a spacecraft. The aircraft may be one of a tethered balloon, an airship, an airplane, a rotorcraft, and an ornithopter, but is not limited thereto.

[0070] The aircraft body 510 is provided with an environmental monitoring system 10 , which is the aforementioned environmental monitoring system 10 ; the laser device 520 is provided in the test cabin 100 .
