Since flying cars can operate in both ground and air environments, it is difficult to grasp the specific values ​​and change patterns of environmental indicators in different areas of the vehicle under different operating conditions and complex weather conditions.

[0058] Specific:

[0059] The rainfall simulator 13 is used to simulate different rainfall levels, which is generally achieved by changing a fixed rainfall simulation system.

[0060] The snowfall simulator 16 simulates different snowfall levels, which is generally achieved by adjusting the snow output of a snowmaking machine.

[0061] The haze generator 17 is used to simulate different haze levels, which is generally achieved by adjusting the flow rate of the air source pump.

[0062] The dust generator 18 is used to simulate different dust levels, which is generally achieved by adjusting the overall module including the dust generator and the fan.

[0063] The air pressure state of the experimental flying car 2 at different flight altitudes is simulated by the air pressure regulator 11 , which is generally achieved through an air pressure control system regulating valve, and the air pressure of the experimental cabin 1 is detected by the pressure sensor 25 .

[0064] The illumination solar simulator 14 simulates different lighting conditions when the experimental flying car 2 is running, which is generally achieved by changing the brightness of the lighting lamp.

[0065] The industrial humidity regulator 8 is used to simulate the different levels of air humidity when the experimental flying car 2 is running, which is generally achieved through an overall module including a dehumidifier, a humidifier and an air circulation system, and the humidity of the experimental cabin 1 is detected by a humidity sensor 23.

[0066] The industrial temperature regulator 9 is used to simulate the different temperatures of the experimental flying car 2 during operation, which is generally achieved through an integrated module of electric heating wires and refrigeration and air conditioning, and the temperature of the experimental cabin 1 is detected by a temperature sensor.

[0067] The decibel regulator 10 is used to simulate different noise conditions when the experimental flying car 2 is running, which is generally achieved through an integral module including a digital-to-analog converter and an amplifier, and the decibel sensor 26 is used to detect the temperature of the experimental cabin 1.

[0068] The air quality of the test chamber 1 is detected by the air quality sensor 27 .

[0069] The vehicle state of the flying car includes the internal state of the vehicle and the running state of the vehicle. In order to simulate the vehicle state of the experimental flying car, the flying car support base platform 3, the flying car motion device 4 and the flying car ground lock are used. The experimental flying car is fixed on the flying car motion device 4 by the flying car ground lock, and the flying car ground lock locks the position of the experimental flying car 2. The flying car motion device 4 is used to drive the flying car to move in the experimental cabin 1. The bottom of the experimental cabin 1 is provided with a regional model support base 5, such as Figure 3 As 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 interior state is simulated by changing the opening and closing status of the windows, different vehicle load conditions, the noise level in the vehicle, the vehicle lighting conditions, the use of the air conditioning system, the use of the electronic equipment in the vehicle, and the vehicle's driving mode.

[0071] The vehicle operation status includes three situations: flying in the air, driving on land and transition 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] This embodiment simulates rainy weather, snowy weather, haze weather and dusty weather through a rain simulator, a snow simulator, a haze generator and a dust generator and transmits them through snow / haze / dust transmission pipelines. The air pressure state is simulated by an air pressure regulator, the light intensity is simulated by an illuminance solar 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 flying car vehicle status platform simulates the multi-scenario working conditions of the flying car.

[0077] After the external climate conditions and the multi-scenario operating condition simulation of the flying car are completed, the real-time environmental health indicator data of 14 test points of the experimental flying car are tested (in-car allergen risk VAR, in-car volatile organic compound VOC, in-car odor intensity VOI, vehicle electromagnetic radiation EMR, in-car particulate matter PM, in-car particulate matter barrier Z, in-car particulate matter purification capacity E), and the data is transmitted to the controller through the ECU.

[0078] The controller uses the various external climate conditions fed back by sensor group 1, the vehicle status of the flying car fed back by sensor group 2, and the environmental health index values ​​of the flying car interior 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 environmental health indicators inside the flying car under multiple scenarios.

[0079] This embodiment can be used to study the test of environmental health indicators inside a flying car, and can simulate a variety of external climate conditions and vehicle conditions, realize the detection of a variety of environmental health indicators inside the car, and the efficient transmission, accurate analysis and comprehensive evaluation of environmental health indicator data.

[0080] Further, for the environmental health indicator data, VAR should meet the following requirements: polybrominated biphenyls, polybrominated diphenyl ethers, antimony ≤ 0.01 (mg / kg), arsenic, lead > 0.01 (mg / kg) and ≤ 0.1 (mg / kg), cadmium > 0.1 (mg / kg) and ≤ 0.4 (mg / kg), hexavalent chromium > 0.4 (mg / kg) and ≤ 0.7 (mg / kg), cobalt, copper > 0.7 (mg / kg) and ≤ 0.9 (mg / kg), nickel > 0.9 (mg / kg) and ≤ 1 (mg / kg); VOC should meet the following requirements: formaldehyde ≤ 0.10 mg / m3, benzene ≤ 0.11mg / m3, toluene ≤ 1.10mg / m3, xylene ≤ 1.50mg / m3, ethylbenzene ≤ 1.50mg / m3, styrene ≤ 0.26mg / m3, acetaldehyde ≤ 0.05mg / m3, acrolein ≤ 0.05mg / m3; VOI ≤ VOI*; EMR ≤ EMR*; PM ≤ PM*; The total score of the Z index is 20 points, and the score is allocated in different intervals according to the Z value measured in the test; The total score of the E index is 80 points, and the score is allocated in different intervals according to the purification time t and the purification end concentration Ct1 measured in the test.

[0083] Embodiment 2:

[0084] This embodiment provides a method for monitoring the environmental health index of a flying car cabin, including the following steps:

[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 nrepresents the 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 levels. When the output value is between 0 and 0.2, it corresponds to the "excellent" level; when the output value is between 0.2 and 0.4, it corresponds to the "better" level; when the output value is between 0.4 and 0.6, it corresponds to the "medium" level; when the output value is between 0.6 and 0.8, it corresponds to the "poor" level; when the output value is between 0.8 and 1, it corresponds to the "poor" level.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
