[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent.

[0031] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0032] The present invention provides a 5G-A sensor fusion precision positioning data acquisition terminal, comprising a communication module, a positioning module, a data acquisition module, a processing module, and a power supply module;

[0033] According to this utility model, the 5G-A sensor fusion precision positioning data acquisition terminal is mounted on a drone. By patrolling the forest, it can promptly detect forest fires and notify firefighters to handle them.

[0034] In this invention, the mounting structure is not limited. Those skilled in the art can use any mounting structure, such as a rope pod, a magnetic mounting, or directly fixing the data acquisition terminal to the lower end of the drone with bolts.

[0035] The communication module is a 5G-A chip. 5G-A is an evolution and enhancement of the 5G network in terms of functionality and coverage, and it achieves significant improvements in network speed, latency, and number of connections.

[0036] The positioning module includes a satellite positioning chip and an accelerometer. Normally, positioning is achieved via satellite. When satellite signals are lost or blocked, inertial measurement is performed using the accelerometer, and positioning is then achieved through inertial navigation. Preferably, assisted positioning is also achieved via a 5G-A base station.

[0037] The data acquisition module includes a temperature sensor 2, a carbon monoxide sensor 3, and a thermal imaging sensor 4.

[0038] The processing module is used to process the positioning signals and the collected data, and sends the processed data to the server through the communication module. It can use any type of MCU chip.

[0039] Temperature sensors and thermal imaging sensors can only detect temperature within their visible range to determine if a fire exists in that area. In this invention, a carbon monoxide sensor is added to further expand the detection range. Specifically, when an increase in carbon monoxide concentration in the air is detected, it indicates that a fire may exist in the nearby area, and the carbon monoxide concentration gradient can indicate the direction of the fire source.

[0040] In a preferred embodiment, the data acquisition module further includes a multispectral camera 5.

[0041] Multispectral cameras can not only record information in the visible light range, but also capture data in the near-infrared light band and perform multi-band data fusion to distinguish flames from high-temperature backgrounds.

[0042] Unlike indoor fire monitoring, forest environments contain high-temperature backgrounds, such as exposed rocks. These backgrounds can prevent thermal imaging sensors from distinguishing between flames and the high-temperature background, leading to false alarms. In this invention, after the thermal imaging sensor detects a high-temperature object, a multispectral camera performs a secondary detection on the object, thereby reducing the false alarm rate and improving detection accuracy.

[0043] Furthermore, after a fire is confirmed, the fire scene is photographed using a multispectral camera, and the photographed content is transmitted to a server using a communication module so that firefighters can observe the fire situation and formulate a fire extinguishing plan.

[0044] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the temperature sensor 2 and the carbon monoxide sensor 3 are disposed on the upper surface of the acquisition terminal housing 1 to prevent the sensors from being directly burned by flames in a fire.

[0045] Preferably, the acquisition terminal housing has one or more recessed holes 6, and the thermal imaging sensor 4 and multispectral camera 5 are disposed in the holes 6, so that the multispectral camera 5 does not protrude from the housing surface, thereby reducing the adhesion of smoke particles caused by fire to the lens and thus preventing image blurring.

[0046] By placing the thermal imaging sensor 4 and the multispectral camera 5 inside the hole, compared to placing them directly on the surface of the acquisition terminal housing, the amount of smoke particles adsorbed can be greatly reduced, thus improving detection accuracy.

[0047] In a preferred embodiment, the lens of the multispectral camera 5 is provided with an antistatic coated glass 51 to reduce the adhesion of smoke particles.

[0048] The antistatic coated glass refers to glass with a transparent antistatic coating. Smoke particles are generally attracted to objects by electrostatic attraction. By applying an antistatic coating, the appearance of smoke particles can be greatly reduced, thus improving the clarity of camera images. In this invention, any known antistatic coating can be used, as long as it can reduce electrostatic attraction.

[0049] More preferably, a gas nozzle 61 is provided inside the hole 6, and gas is sprayed onto the antistatic coated glass 51 through the gas nozzle 61 to clean the adsorbed smoke particles.

[0050] Preferably, the gas nozzles 61 are multiple and arranged in a ring on the outside of the antistatic coated glass 51, so that the gas can clean the entire antistatic coated glass 51.

[0051] In this invention, the gas source of the gas nozzle 61 is not limited. For example, a compressed gas tank can be set in the collection terminal to provide high-pressure gas, or a micro air pump can be used to filter and compress external gas for use.

[0052] According to this utility model, the gas nozzle 61 does not need to be turned on for a long time, but only needs to be turned on intermittently at the fire scene.

[0053] In a preferred embodiment, ceramic isolation plates are provided on the bottom and sides of the acquisition terminal housing. The ceramic isolation plates can withstand instantaneous high temperatures and protect the acquisition terminal housing and internal components from being directly burned by flames in a short period of time, thus preventing deformation and damage. This ensures that the acquisition terminal can achieve short-term disaster data collection at the fire scene.

[0054] In a preferred embodiment, the power module uses a solid-state battery, which is a type of battery that uses a solid electrolyte instead of a traditional liquid electrolyte. It has significant advantages in temperature resistance. In particular, high-temperature resistant solid-state batteries can still maintain good performance at 60°C to 100°C, solving the problem of rapid capacity drop or even thermal runaway of traditional batteries at high temperatures.

[0055] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship in the working state of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] The present invention has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and serve only an illustrative purpose. Based on this, various substitutions and improvements can be made to the present invention, all of which fall within the protection scope of the present invention.
