[0058] Specifically:
[0059] The rainfall simulator 13 is used to simulate different degrees of rainfall, generally achieved by changing the fixed simulation rainfall system.
[0060] The snowfall simulator 16 is used to simulate different degrees of snowfall, generally achieved by adjusting the snow output of the snow maker.
[0061] The haze generator 17 is used to simulate different degrees of haze, generally achieved by adjusting the flow rate of the air source pump.
[0062] The different degrees of dust are simulated by the dust generator 18, generally achieved by adjusting the overall module including the dust generator and the fan.
[0063] The air pressure states of the experimental flying car 2 at different flying heights are simulated by the air pressure regulator 11, generally achieved by regulating valves in the air pressure control system, and the air pressure in the experimental cabin 1 is detected by the pressure sensor 25.
[0064] The different lighting conditions during the operation of the experimental flying car 2 are simulated by the illuminance sunlight simulator 14, generally achieved by changing the brightness of the lighting lamp.
[0065] The different degrees of air humidity during the operation of the experimental flying car 2 are simulated by the industrial humidity regulator 8, generally achieved by the overall module including the dehumidifier, humidifier and air circulation system, and the humidity in the experimental cabin 1 is detected by the humidity sensor 23.
[0066] The different temperatures during the operation of the experimental flying car 2 are simulated by the industrial temperature regulator 9, generally achieved by the overall module of the electric heating wire and the refrigeration air conditioner, and the temperature in the experimental cabin 1 is detected by the temperature sensor.
[0067] The different noise conditions during the operation of the experimental flying car 2 are simulated by the decibel regulator 10, generally achieved by the overall module including the digital-to-analog converter and the amplifier, and the temperature in the experimental cabin 1 is detected by the decibel sensor 26.
[0068] The air quality in the experimental cabin 1 is detected by the air quality sensor 27.
[0069] The vehicle state of the flying car includes the vehicle internal state and the vehicle operation state. To simulate the vehicle state of the experimental flying car, it is achieved through the flying car support base platform 3, the flying car motion device 4 and the flying car ground lock. The experimental flying car is fixed on the flying car motion device 4 by the flying car ground lock, the flying car ground lock locks the position of the experimental flying car 2, and the flying car motion device 4 is used to drive the flying car to move in the experimental cabin 1. There is a regional model support base 5 at the bottom inside the experimental cabin 1, as Figure 3 shown, the upper part of the regional model support base 5 is connected to the urban model 6 and the mountain model 7, and hydraulic columns are also provided at the bottom of the urban and mountain models.
[0070] The vehicle internal state is simulated by changing the opening and closing state of the windows, different load conditions of the vehicle, the noise level inside the vehicle, the lighting conditions of the vehicle, the use of the air conditioning system, the use of in-vehicle electronic devices, and the driving mode of the vehicle.
[0071] The vehicle operation state includes three situations: flying in the air, driving on land, and transitional driving.
[0072] In the land driving test, the flying car is driven to move by the flying car motion device 4, and the flying car ground lock is used to fix the flying car to the flying car motion device 4, so that the relative position between the flying car and the flying car motion device 4 remains unchanged. Figure 4 As shown, through the unilateral lifting and rotating movements of the flying car movement device 4, the land driving test of the flying car starting / constant speed / acceleration / deceleration / turning / climbing / idling / braking is realized.
[0073] During the flight test, the propeller and the experimental flying car are positioned by a laser device installed at the bottom of the propeller 42 support of the mechanical arm. Figure 5 As shown, the four propellers are located in the same plane, and the propellers are adjusted by the mechanical arm so that the angles between the mechanical arm propeller 42 and the experimental flying car 2 and the horizontal ground are consistent, and the relative position change between the propeller and the experimental flying car 2 depends on the movement of the mechanical arm joint. In addition, the position of the mechanical arm can be changed by sliding the guide rail 43 set on the top of the experimental cabin 1. At the same time, the flying car is fixed on the flying car motion device 4 by the flying car ground lock. The flying car is driven to move in the experimental cabin by the lifting and rotating flying car motion device 4; the land conditions below the flying car during actual flight are simulated by the model support base and the urban model and mountain model connected thereto. By adjusting the lifting hydraulic column directly connected to the model support base, the diverse terrains encountered by the flying car below in the actual flight are simulated, including mountainous areas and urban areas of different heights and different forms, so as to simulate the changes in the airflow below the flying car during flight. A vertical take-off / vertical landing / level flight / hovering / turning / circling / diving / jumping aerial flight test of the flying car in the experimental cabin is realized.
[0074] In the transition driving test, by controlling the start and stop of the robotic arm and the movement of the flying car's motion device, the flying car can achieve the transition driving test from land driving to air flying, and from air flying to land driving.
[0075] The experimental cabin 1 is based on its cabin panel structure, with polyurethane as the core material and supplemented by thermal insulation materials. It combines many advantages such as corrosion resistance, aging resistance, flame retardancy, non-toxicity, economy, lightness and durability, stable structure, high compressive strength, and reliable and beautiful appearance.
[0076] In this embodiment, a rainfall simulator, a snowfall simulator, a haze generator, and a sandstorm generator are used, and simulated rainfall weather, snowfall weather, haze weather, and sandstorm weather are conveyed through snow / haze / sand conveying pipelines. The air pressure state is simulated by a pressure regulator, the light intensity is simulated by an illuminance sunlight simulator, the air humidity is simulated by an industrial humidity regulator, the ambient temperature is simulated by an industrial temperature regulator, the external sound level is simulated by a decibel regulator, and the multi-scenario working conditions of a flying car are simulated by a flying car vehicle state platform.
[0077] After the simulation of the external climate state and the multi-scenario working conditions of the flying car is completed, real-time environmental health index data of 14 test points of the experimental flying car are detected (risk of allergens VAR in the vehicle, volatile organic compounds VOC in the vehicle, odor intensity VOI in the vehicle, vehicle electromagnetic radiation EMR, particulate matter PM in the vehicle, particulate matter barrier Z in the vehicle, particulate matter purification ability E in the vehicle), and the data is transmitted to the controller through the ECU.
[0078] Based on the various external climate states fed back by the first sensor group, the vehicle state of the flying car fed back by the second sensor group, and the environmental health index values inside the flying car fed back by the third sensor group as the input of the convolutional neural network, the convolutional neural network outputs the spatial distribution and variation characteristics of the environmental health index inside the flying car under multi-scenario working conditions.
[0079] This embodiment can be used to study the test of the environmental health index inside a flying car, can simulate various external climate states and vehicle states, realize the detection of various environmental health indexes inside the vehicle, as well as the efficient transmission, precise analysis, and comprehensive evaluation of environmental health index data.
[0080] Furthermore, for the environmental health indicator data, the following analysis is carried out, and VAR should meet the following requirements: for polybrominated biphenyls, polybrominated diphenyl ethers, and antimony, it should be ≤ 0.01 (mg / kg); for arsenic and lead, it should be > 0.01 (mg / kg) and ≤ 0.1 (mg / kg); for cadmium, it should be > 0.1 (mg / kg) and ≤ 0.4 (mg / kg); for hexavalent chromium, it should be > 0.4 (mg / kg) and ≤ 0.7 (mg / kg); for cobalt and copper, it should be > 0.7 (mg / kg) and ≤ 0.9 (mg / kg); for nickel, it should be > 0.9 (mg / kg) and ≤ 1 (mg / kg). VOC should meet the following requirements: for formaldehyde, it should be ≤ 0.10 mg / m3; for benzene, it should be ≤ 0.11 mg / m3; for toluene, it should be ≤ 1.10 mg / m3; for xylene, it should be ≤ 1.50 mg / m3; for ethylbenzene, it should be ≤ 1.50 mg / m3; for styrene, it should be ≤ 0.26 mg / m3; for acetaldehyde, it should be ≤ 0.05 mg / m3; for acrolein, it should be ≤ 0.05 mg / m3. VOI ≤ VOI*; EMR ≤ EMR*; PM ≤ PM*. The total score of the Z index is 20 points, and according to the measured Z value in the test, the score is allocated in different intervals. The total score of the E index is 80 points, and according to the measured purification time t and the purification termination concentration Ct1 in the test, the score is allocated in different intervals. For the environmental health indicators with limits, if they do not meet the limits, it is determined that they do not meet the environmental health requirements, and finally, a three-dimensional distribution map of the vehicle environmental health grade as shown in Figure 6 is formed.
[0081] The system of this embodiment comprehensively considers the impacts of various external climate states, different vehicle internal states, and vehicle motion states on the in-vehicle environment of the flying car, enhancing the comprehensiveness and accuracy of the in-vehicle environment test of the flying car. Multiple position points are designed in the vehicle to detect various index parameters such as the risk of sensitizing substances VAR in the vehicle, volatile organic compounds VOC in the vehicle, odor intensity VOI in the vehicle, vehicle electromagnetic radiation EMR, particulate matter PM in the vehicle, particulate matter barrier Z in the vehicle, and particulate matter purification ability E in the vehicle, so as to test the spatial distribution and change characteristics of the in-vehicle environmental health indicators, providing necessary support for studying the in-vehicle environment health of the flying car under various external climate states and vehicle states.

[0085] By simulating external climate conditions, including rain, snow, haze, dust, light, air pressure, humidity, temperature, decibels and other external climate conditions.
[0086] The vehicle status of the experimental flying car is simulated, including three situations: air flight, land driving, and transition driving. Among them, air flight includes vertical take-off / vertical landing / level flight / hovering / turning / circling / diving / jumping / emergency operations; land driving includes starting / constant speed / acceleration / deceleration / turning / climbing / idling / braking operations; transition driving includes from land driving to air flight and from air flight to land driving. The internal state of the experimental flying car is simulated by adjusting the opening and closing state of the windows, the noise level in the car, the use of the air conditioning system, different load conditions of the vehicle, different engine speeds, the lighting conditions of the vehicle, the use of electronic equipment in the car, and the driving mode of the vehicle.
[0087] The conditions of the experimental cabin under various external climate conditions are obtained through a No. 1 sensor group installed on the inner wall of the experimental cabin, and the conditions are fed back to the controller;
[0088] The real-time vehicle status of the flying car is simulated and fed back to the controller by means of a second sensor group installed in the flying car motion device and the flying car;
[0089] The three sensor groups set at the first, second, third, fourth and fifth points are used to obtain the real environmental health index values inside the flying car and feed them back to the controller;
[0090] The controller uses sensor group No. 1 to feedback the conditions of the experimental cabin under various external climate conditions, sensor group No. 2 to feedback the real-time vehicle status of the experimental flying car, and sensor group No. 3 to feedback the health index values of the flying car's interior environment.
[0091] The controller uses the various external climate conditions fed back by sensor group 1, the vehicle operating conditions of the flying car fed back by sensor group 2, and the values of the flying car's interior environmental health indicators fed back by sensor group 3 as inputs to the convolutional neural network. The convolutional neural network outputs the spatial distribution and change characteristics of the interior environmental health indicators under multiple scenarios.
[0092] The calculation formula for the health index of the interior environment of the experimental flying car is:
[0093]
[0094] Where N represents the number of sensor sites, w nThe weight of the environmental health index of site n, H n Represents the environmental health index of site n.
[0095] The output value of the convolutional neural network is divided into five grade intervals. When the output value is between 0 and 0.2, it corresponds to the "excellent" grade; when the output value is between 0.2 and 0.4, it corresponds to the "relatively excellent" grade; when the output value is between 0.4 and 0.6, it corresponds to the "medium" grade; when the output value is between 0.6 and 0.8, it corresponds to the "poor" grade; when the output value is between 0.8 and 1, it corresponds to the "very poor" grade.
[0096] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
