[0066] The present application will be further described in detail below with reference to the accompanying drawings.

[0067] An embodiment of the present application provides a low-altitude equipment multi-physical field coupling wind tunnel test method, which can be executed by an electronic device. The electronic device can be a server or a terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0068] Figure 1 is a structural schematic diagram of a multi-physical field coupling wind tunnel provided by an embodiment of the present application.

[0069] As Figure 1As shown in the low-altitude equipment multi-physical field coupling wind tunnel test method is applied to a multi-physical field coupling wind tunnel, the multi-physical field coupling wind tunnel comprises a base 1, the upper surface of the base 1 is fixedly connected with a simulation cabin 2, one side wall of the simulation cabin 2 is provided with a plurality of horizontal flow fans 3, the upper surface of the base 1 is provided with a plurality of rotating flow fans 4 arranged around the simulation cabin 2, and the top of the simulation cabin 2 is provided with a plurality of vertical flow fans 5. The horizontal flow fan 3, the rotating flow fan 4 and the vertical flow fan 5 can realize the construction of multiple wind field types, so as to meet the test requirements of low-altitude equipment on different wind fields.

[0070] Figure 1 A flowchart of a low-altitude equipment multi-physical field coupling wind tunnel test method provided in the embodiment of the application.

[0071] As Figure 1 shown, the main process of the method is described as follows (steps S101-S105):

[0072] In step S101, the wind field simulation requirement information of the user, the low-altitude equipment information and the wind field type are obtained, wherein the wind field type includes a uniform laminar flow mode, a turbulent flow mode, a wind shear mode, a time-varying wind mode, a gust mode, a tornado wind mode and a downburst mode.

[0073] In the embodiment, when the wind tunnel test scheme is created, the user needs to describe the requirements or directly determine the desired wind field type. However, some users cannot clearly specify the specific performance of the actual desired wind field type when using. Therefore, the wind field simulation requirement information of the user is obtained, and subsequent processing is performed according to the wind field simulation requirement information provided by the user. The wind field simulation requirement information includes the direction of wind blowing, the size of wind volume, the type name of wind in reality, etc. The low-altitude equipment information is the model, power and use time of the low-altitude equipment to be tested, etc. The wind field type is the mode of wind that can be provided by the multi-physical field coupling wind tunnel.

[0074] The multi-physical field coupling wind tunnel can provide seven types of wind fields in the application, and the seven types of wind fields are uniform laminar flow mode, turbulent flow mode, wind shear mode, time-varying wind mode, gust mode, tornado wind mode and downburst mode. The uniform laminar flow mode is a horizontal wind formed by a single horizontal flow fan. In the uniform laminar flow mode, the vertical flow fan and the rotating flow fan do not work. At the same time, the number and position of the vertical flow fan used are selected according to the actual wind position. The turbulent flow mode is also a wind formed by a single horizontal flow fan. In the turbulent flow mode, the vertical flow fan and the rotating flow fan do not work. The effect of turbulent flow is achieved by adjusting the number and position of the vertical flow fan used. At the same time, the number and position of the vertical flow fan used are selected according to the actual wind position. The wind shear mode is also a wind formed by a single horizontal flow fan. In the wind shear mode, the vertical flow fan and the rotating flow fan do not work. The wind shear is presented by controlling the vertical flow fan to change in steps. The time-varying wind mode is also a wind formed by a single horizontal flow fan. In the wind shear mode, the vertical flow fan and the rotating flow fan do not work. The time-varying wind is presented by controlling the vertical flow fan to change in stages. The gust mode is also a wind formed by a single horizontal flow fan. In the gust mode, the vertical flow fan and the rotating flow fan do not work. The gust is presented by controlling the vertical flow fan to change sharply. The tornado wind mode is a wind formed by the cooperation of the vertical flow fan and the rotating flow fan. In the tornado wind mode, the vertical flow fan is used to present the tornado wind by air suction. The downburst mode is a wind formed by the cooperation of the vertical flow fan and the rotating flow fan. In the downburst mode, the vertical flow fan is used to present the downburst by blowing. It should be noted that the use of the fan is only described simply here, that is, the cooperation of the three fans can achieve various types of wind fields, and the actual more detailed formation method of the wind field type is not described here.

[0075] In step S102, the to-be-executed wind field type and the fan output information are determined based on the simulation demand information and the wind field type.

[0076] For step S102, the type keyword of the wind field type and the fan output keyword are obtained; the demand keyword is generated by keyword extraction on the simulation demand information; the demand keyword is matched with the type keyword to generate a first matching result; the to-be-executed wind field type is determined based on the first matching result and the type keyword; the demand keyword is matched with the fan output keyword to generate a second matching result; the fan output wind level is determined based on the second matching result and the fan output keyword; the fan output rule is obtained; and the fan output information is determined based on the fan output wind level and the fan output rule.

[0077] In the embodiment, in order to determine the wind field type required by the user, that is, to determine the to-be-executed wind field type to be executed this time, the type keyword of the wind field type and the fan output keyword are set, and the keywords of the requirement information are extracted to determine the keywords of the simulation requirement this time. The requirement keywords are matched with the type keywords, the type keywords matched with the requirement keywords are found, the type keywords matched with the requirement keywords are summed up to obtain a first matching result. Then, the wind field type is determined according to the first matching result and the type keyword, and the determined wind field type is taken as the to-be-executed wind field type. Then, the same way is used to determine a second matching result, that is, the requirement keywords are matched with the fan output keywords, the fan requirement keywords matched with the requirement keywords are found, the fan requirement keywords matched with the requirement keywords are summed up to obtain a second matching result. Then, the fan output wind level is determined according to the second matching result and the fan output keyword, and the fan output information is determined according to the fan output rule set in advance. The fan output wind level is the wind level required by the fan during the test. The wind level here is consistent with the wind level of the wind generated in nature. For example, when weather forecasting is performed, the wind direction and wind level are indicated, such as southeast wind 3 to 5 levels. In the application, the fan output wind level is the same as the concept of the wind level in weather forecasting. However, the fan output wind level may or may not correspond to the general wind level. For example, when the forecasted wind level is 2 levels, the fan output wind level is 1 level. The specific corresponding relationship and the setting of the fan output wind level need to be set according to the actual requirement, which is not limited here.

[0078] The fan output rule sets different fan output wind levels and fan output situations of each fan output wind level, such as the output frequency of the fan driving frequency converter, the rotating speed of the fan, the blowing direction of the fan, and the like. The fan output wind level and the output situation are summed up to obtain the final fan output information.

[0079] In step S103, the test execution time length of the target test equipment is determined based on the to-be-executed wind field type and the low-altitude equipment information.

[0080] For step S103, the single shortest execution time length of the to-be-executed wind field type and the type number of the to-be-executed wind field type are obtained. The safe flight time length is determined based on the low-altitude equipment information. The target flight time length is determined based on the single shortest execution time length and the type number. The test execution time length of the target test equipment is determined based on the safe flight time length and the target flight time length.

[0081] In the embodiment, in order to ensure the integrity and effectiveness of the test results, when the target test equipment is tested, it is necessary to ensure that the target test equipment is in a normal flight state throughout the test, that is, there is no sudden power failure during flight to cause the test to not proceed normally. Therefore, the test execution time needs to be determined. Different types of wind fields have certain limitations when starting, that is, the time is too short to achieve the corresponding wind field effect. Each type of wind field is set with a single minimum execution time, that is, within the single minimum execution time, the wind field of this type can achieve the corresponding wind field effect. According to the type quantity of the to-be-executed wind field type and the single minimum execution time, the target flight time is determined, and then the target flight time is adjusted according to the safe flight time to obtain the final test execution time.

[0082] Further, when the target flight time is adjusted according to the safe flight time, it is judged whether the safe flight time is not less than the target flight time; if the safe flight time is not less than the target flight time, the target flight time is taken as the test execution time of the target test equipment; if the safe flight time is less than the target flight time, the time difference between the target flight time and the safe flight time is calculated; the limit flight time of the target test equipment is obtained; whether the target test equipment can complete the flight is judged based on the limit flight time and the time difference; if the target test equipment can complete the flight, the limit flight time is taken as the test execution time of the target test equipment; if the target test equipment cannot complete the flight, the target flight time is split based on the type quantity and the safe flight time, and the test execution time of the target test equipment is determined based on the split result.

[0083] First, the two flight times need to be compared to determine whether the safe flight time can support the completion of the test of all to-be-executed wind field types, that is, whether the safe flight time is not less than the target flight time. If the safe flight time is not less than the target flight time, it means that the safe flight time can support the completion of the test of all to-be-executed wind field types, and the safe flight time can be directly taken as the test execution time. If the safe flight time is less than the target flight time, it means that the safe flight time cannot support the completion of the test of all to-be-executed wind field types, and further judgment is needed. In the further judgment, the limit flight time of the target test equipment is used for judgment, and the time difference between the target flight time and the safe flight time is calculated. Generally, the limit flight time is obtained at the same time as the time difference from the target flight time, so that the limit flight time can be determined by the time difference whether it can support the test of all to-be-executed wind field types. If it can support, the limit flight time is taken as the test execution time. If it cannot support, the target flight time needs to be split, and the test execution time is determined according to the split result.

[0084] In the splitting of the target flight duration, the target flight duration is first divided according to the safe flight duration to obtain a split duration, then the split duration is adjusted by the single shortest execution duration to generate an adjusted duration, and then all the adjusted durations are taken as the test execution duration. When performing the test, the test is performed according to the adjusted duration in turn, that is, after performing an adjusted duration, the target test equipment is charged or the battery is replaced, and after charging, the next adjusted duration is performed, until all the adjusted durations are performed. For example, there are four types of wind field types to be executed, which are horizontal laminar flow mode, single shortest execution duration is 3 minutes, time wind variable mode, single shortest execution duration is 5 minutes, gust mode, single shortest execution duration is 3 minutes, and tornado mode, shortest execution duration is 8 minutes. The safe flight duration is 10 minutes, and the limit flight duration is 12 minutes. When dividing, two split durations are obtained, which are the first split duration of 10 minutes and the second split duration of 8 minutes. However, when performing, the gust mode is occupied by two split durations, so adjustment is needed. When adjusting, it is necessary to ensure that the gap between each split duration cannot be too large and cannot exceed the limit flight duration. The threshold value can be set to limit, so that the gust mode is divided into the first split duration, thereby obtaining two adjusted durations, which are the first adjusted duration of 11 minutes and the second adjusted duration of 8 minutes. It should be noted that the specific splitting method needs to be set according to actual needs, and only one splitting method is provided here for illustration, and is not limited here.

[0085] In step S104, a wind tunnel test scheme is generated based on the to-be-executed wind field type, the fan output information and the test execution duration.

[0086] For step S104, the flow fan type used when executing the to-be-executed wind field type is obtained; the execution order of the to-be-executed wind field type is determined based on the flow fan type; the start-stop time and the change time of the flow fan corresponding to the to-be-executed wind field type are determined based on the execution order and the test execution duration; the fan output information is bound with the change time based on the execution order to generate a binding result; and the wind tunnel test scheme is generated based on the binding result and the start-stop time.

[0087] Further, when determining the start-stop time and the change time of the flow fan corresponding to the to-be-executed wind field type according to the execution order and the test execution duration, the horizontal execution duration of the horizontal flow fan, the vertical execution duration of the vertical flow fan and the rotation execution duration of the rotating flow fan are determined based on the execution order; the start-stop time of the flow fan corresponding to the to-be-executed wind field type is determined based on the horizontal execution duration, the vertical execution duration and the rotation execution duration; the fan angle information of the to-be-executed wind field type is obtained; and the change time of the flow fan corresponding to the to-be-executed wind field type is determined based on the fan angle information, the horizontal execution duration, the vertical execution duration and the rotation execution duration.

[0088] In the embodiment, there are three types of flow fans, i.e., horizontal flow fan, vertical flow fan and rotating flow fan. In use, the vertical flow fan and the rotating flow fan are used only in the downburst mode and the tornado mode. Therefore, when the two modes are used, the two modes are placed at the beginning or the end, and then the wind field types to be executed using the horizontal flow fan are sorted. In the simulation experiment, only when a wind field type is executed, the next wind field type can be executed. Therefore, the start-stop time is determined according to the shortest execution time and the test execution time. Then, the change time of the corresponding flow fan is determined according to the execution of the flow fan of each wind field type to be executed, the execution sequence and the fan angle information. That is, the change time of the flow fan corresponding to the wind field type to be executed is determined according to the fan angle information, the horizontal execution time, the vertical execution time and the rotating execution time. Then, the fan output information and the change time are bound according to the execution sequence to generate a binding result. The binding result and the start-stop time are used as the wind tunnel test scheme.

[0089] In the embodiment, the environmental simulation requirement information is obtained. The environmental simulation temperature and the environmental simulation humidity are determined based on the environmental simulation requirement information. The adjustment parameter of the environmental simulation device is determined based on the environmental simulation temperature and the environmental simulation humidity. The wind tunnel test scheme is generated based on the adjustment parameter, the binding result and the start-stop time.

[0090] In addition to the basic wind field type, the environmental simulation device for temperature and humidity mode is also provided. The environmental simulation device can be increased according to the actual requirement. When the environmental simulation device is provided, the environmental simulation temperature and the environmental simulation humidity are determined according to the environmental simulation requirement information provided by the user. The environmental simulation requirement information can be the exact temperature value and humidity value, or the region and the time information of the region, such as the weather in Guangzhou in January, the weather in Beijing in June, the weather in Shenyang in October, etc. The corresponding environmental simulation temperature and environmental simulation humidity are determined by comparing and querying the preset information table. The simulation error of the environmental simulation device is obtained, i.e., the error value generated during simulation, such as the actual temperature generated when the temperature is set to 10 degrees is 9 degrees. The adjustment parameter is determined according to the simulation error. The adjustment parameter is the adjusted environmental simulation temperature and environmental simulation humidity. Then, the adjustment parameter, the binding result and the start-stop time are bound to generate the wind tunnel test scheme.

[0091] In step S105, at least one flow fan is controlled to work based on the wind tunnel test scheme.

[0092] In the embodiment, the flow fan is controlled and adjusted by the wind tunnel test scheme, so as to realize the test of the target test equipment.

[0093] In the embodiment, execution information of the wind tunnel test scheme is acquired in real time, and the execution information is displayed and stored.

[0094] In order to facilitate management and viewing, when the wind tunnel test scheme is executed, the execution information of the line management is acquired in real time, and the execution information is displayed on the display interface, and after the execution of the wind tunnel test scheme is completed, all the execution information is stored.
