Description

Technical Field

[0001] This utility model relates to the field of meteorological radar technology, and in particular to a cloud and fog data acquisition device and a cloud and fog data acquisition instrument. Background Technology

[0002] Clouds and fog are aerosol systems composed of numerous tiny water droplets or ice crystals suspended in the near-surface air. These droplets or crystals are products of water vapor condensation (or sublimation) in the near-surface air. Clouds and precipitation have significant impacts on the energy balance between the Earth and the atmosphere, climate change, the ecological environment, and disaster prevention and relief. Dense fog causing low visibility has become one of the most significant hazardous weather events affecting economic and social development and public health. Conventional cloud and fog data acquisition devices are typically insufficient for large-scale, dense observations and are also bulky and heavy, making them unsuitable for flexible observation when mounted on drones.

[0003] In summary, how to design a cloud and fog data acquisition device to cooperate with UAVs for cloud and fog data acquisition is a problem that needs to be solved in this field. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a cloud and fog data acquisition device, a cloud and fog data acquisition instrument, a processing method, equipment, and medium. The designed cloud and fog data acquisition device can be used in conjunction with a drone to collect cloud and fog data. The specific solution is as follows:

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] Clouds and fog are aerosol systems composed of numerous tiny water droplets or ice crystals suspended in the near-surface air. These droplets or crystals are products of water vapor condensation (or sublimation) in the near-surface air. Clouds and precipitation have significant impacts on the energy balance between the Earth and the atmosphere, climate change, the ecological environment, and disaster prevention and relief. Dense fog causing low visibility has become one of the most significant hazardous weather events affecting economic and social development and public health. Conventional cloud and fog data acquisition devices are typically insufficient for large-scale, dense observations and are also bulky and heavy, making them unsuitable for flexible observation when mounted on drones.

[0024] Therefore, this application provides a cloud and fog data acquisition device, a cloud and fog data acquisition instrument, a processing method, equipment, and medium. The designed cloud and fog data acquisition device can cooperate with drones to collect cloud and fog data.

[0025] See Figure 1 As shown in the figure, this application discloses a cloud and fog data acquisition device, including:

[0026] Packaging container 1, including mounting base and container lid;

[0027] A miniature millimeter-wave radar 12 is installed inside the packaging container 1 and is used to collect raw data frames of clouds and fog.

[0028] A miniature lidar 13 is installed inside the packaging container 1 to collect echo signals characterizing the intensity of clouds and fog.

[0029] A network sharing device 14 is disposed inside the packaging container 1, and a first serial data bus for transmitting the original cloud and fog data frame is provided between the network sharing device 14 and the miniature millimeter-wave radar 12, and a second serial data bus for transmitting the echo signal is provided between the network sharing device 14 and the miniature lidar 13, so that the network sharing device 14 can wirelessly transmit the original cloud and fog data frame and the echo signal to the data processing terminal.

[0030] The packaging container 1 in the cloud and fog data acquisition device is used to install and fix the miniature millimeter-wave radar 12, miniature lidar 13, and network sharing device 14. Installing the miniature millimeter-wave radar 12, miniature lidar 13, and network sharing device 14 inside the packaging container 1 also serves a waterproof function. Because clouds and fog contain a lot of moisture, the damage to the device over time is not negligible. Therefore, placing the miniature millimeter-wave radar 12, miniature lidar 13, and network sharing device 14 inside the packaging container 1 can not only fix each radar, but also protect the radar and network sharing device from damage caused by fog and water.

[0031] A miniature millimeter-wave radar 12 is housed inside the packaging container 1, enabling it to detect vertically upwards to collect raw cloud and fog data frames. A miniature lidar 13 is also housed inside the packaging container 1, enabling it to detect vertically upwards to collect echo signals characterizing cloud and fog intensity. Compared to large millimeter-wave cloud radars, the miniature millimeter-wave radar 12 and lidar 13 have extremely low cost, very small blind spots, and high resolution, making them more suitable for analyzing the fine spatial structure of clouds and fog. Compared to fog droplet spectrometers, they have extremely low cost, very small size and weight, and can support large-scale, multi-point observations, and can be used in conjunction with UAV observations.

[0032] For example Figure 2 The diagram illustrates a specific cloud and fog data acquisition device. A network sharing unit 14 is installed inside the packaging container 1. The network sharing unit 14 is connected to a miniature millimeter-wave radar 12 and a miniature lidar 13 via a first serial data bus and a second serial data bus, respectively. In this way, the network sharing unit 14 can receive the raw cloud and fog data frames collected by the miniature millimeter-wave radar 12 through the first serial data bus, and the network sharing unit 14 can also receive the echo signals collected by the miniature lidar 13 through the second serial data bus, so that the network sharing unit 14 can wirelessly transmit the raw cloud and fog data frames and echo signals to the data processing terminal.

[0033] In this embodiment, the mounting base is a foam plastic box. Specifically, the mounting base can be a foam plastic box, and the shape of the foam plastic box can be a cuboid. The mounting base can be composed of five sides: bottom, front, back, left, and right. These sides can all be made of foam plastic boards. Thus, the mounting base is a foam plastic box.

[0034] In this embodiment, the container lid includes a foam plastic layer and / or a waterproof layer. In a first specific case, the container lid may specifically include a foam plastic layer; in a second specific case, the container lid may specifically include a waterproof layer; in a third specific case, the container lid includes both a foam plastic layer and a waterproof layer. Foam plastic is relatively inexpensive and has a relatively low impact on millimeter waves and lasers, so the container lid may specifically be a foam plastic layer. Waterproof layers are generally more expensive and generally have a lower impact on millimeter waves and lasers than foam plastic, so the container lid may specifically be a waterproof layer. It is understood that the container lid may also be a combination of a foam plastic layer and a waterproof layer.

[0035] In this embodiment, the waterproof layer is located in the observation direction of the miniature lidar. Lidar senses the surrounding environment by emitting a laser beam and receiving the reflected signal. This process requires extremely high cleanliness and integrity of the optical components. Moisture (such as rainwater, fog, etc.) may adhere to the lidar lens or housing, causing abnormal laser scattering, absorption, or reflection, thereby affecting the accuracy and stability of the signal. Due to its sensitivity to moisture and the requirements of its application scenarios, miniature lidar usually needs to have a waterproof layer added to ensure normal operation.

[0036] In this embodiment, the waterproof layer is infrared high-transmittance glass. Infrared high-transmittance glass increases the transmittance of infrared light, thereby reducing the attenuation of the lidar signal. Using infrared high-transmittance glass as a lidar radome can significantly improve the detection range and imaging resolution of the lidar, while reducing the interference of environmental factors on the lidar performance.

[0037] In this embodiment, the cloud and fog data acquisition device further includes a support rod penetrating the packaging container, used to fix the miniature millimeter-wave radar inside the packaging container, so that the miniature millimeter-wave radar does not directly contact the inner wall of the packaging container. Millimeter waves refer to electromagnetic waves with wavelengths from 0.1 to 1 cm, corresponding to a frequency range of 30 to 300 GHz. If the packaging container is in direct contact with the millimeter-wave radar, the inner wall of the packaging container may interfere with the propagation of radar waves, leading to signal attenuation or misjudgment. Furthermore, if the surface of the packaging container is relatively rough, i.e., if the surface of the packaging container has many tiny unevennesses, these uneven surfaces may scatter millimeter waves, reducing the detection accuracy and stability of the radar. For example... Figure 2As shown, the support rod passes through the packaging container, and the miniature millimeter-wave radar is then mounted on the support rod. Therefore, the miniature millimeter-wave radar can be fixed inside the packaging container using the support rod, and the miniature millimeter-wave radar does not directly contact the inner wall of the packaging container. The support rod can be a wooden stick.

[0038] In this embodiment, the first serial data bus and the second serial data bus are Universal Asynchronous Receivers / Transmitters (UARTs). Specifically, the first serial data bus and the second serial data bus are UARTs. UARTs do not need to share the same clock; the clock frequencies of the communicating parties only need to be consistent during transmission. That is, miniature millimeter-wave radar and miniature lidar detect cloud and fog echoes and transmit signals to a USB network sharing device via the UART serial port.

[0039] The beneficial effects of this application are as follows: The cloud and fog data acquisition device of this application includes a packaging container, including a mounting base and a container lid; a miniature millimeter-wave radar, disposed inside the packaging container, for acquiring raw cloud and fog data frames; a miniature lidar, disposed inside the packaging container, for acquiring echo signals characterizing cloud and fog intensity; and a network sharing device, disposed inside the packaging container, wherein a first serial data bus for transmitting the raw cloud and fog data frames is provided between the network sharing device and the miniature millimeter-wave radar, and a second serial data bus for transmitting the echo signals is provided between the network sharing device and the miniature lidar, so that the network sharing device wirelessly transmits the raw cloud and fog data frames and the echo signals to the data processing terminal. Therefore, the miniature millimeter-wave radar and miniature lidar in the cloud and fog data acquisition device of this application are small in size and light in weight, and support large-area multi-point observation. Therefore, they can be installed on UAVs to cooperate with UAVs in collecting raw cloud and fog data frames and echo signals characterizing cloud and fog intensity. Furthermore, the cloud and fog data acquisition device also includes a network sharing device, and the network sharing device is connected to the miniature millimeter-wave radar and miniature lidar respectively by a first serial data bus and a second serial data bus, which can be used to transmit raw cloud and fog data frames and echo signals respectively. In this way, the network sharing device wirelessly transmits the raw cloud and fog data frames and echo signals to the data processing end. That is to say, because the cloud and fog data acquisition device is small in size and light in weight, and can wirelessly transmit the collected cloud and fog data to the data processing end, it can be installed on UAVs to cooperate with UAVs in collecting cloud and fog data.

[0040] Furthermore, this application also provides a cloud and fog data acquisition device, including the cloud and fog data acquisition apparatus disclosed above. The cloud and fog data acquisition device includes a packaging container, a miniature millimeter-wave radar, a miniature lidar, and a network sharing unit. The miniature millimeter-wave radar, miniature lidar, and network sharing unit are all disposed within the packaging container. A first serial data bus for transmitting raw cloud and fog data frames is provided between the network sharing unit and the miniature millimeter-wave radar, and a second serial data bus for transmitting echo signals is provided between the network sharing unit and the miniature lidar. The network sharing unit is used to wirelessly transmit the raw cloud and fog data frames and echo signals to a data processing terminal.
