[0025] Figure 1 This is an application environment diagram of the drone testing method provided in the embodiment of the present application. Figure 1 This drone testing method is applied to a drone testing system. The drone testing system includes a test terminal 110 and a host computer 120. The test terminal 110 and the host computer 120 are connected via a network. The test terminal 110 is connected to the drone. More specifically, the test terminal 110 is connected to the drone's power system's electronic speed controller and the drone's power supply, which supplies power to the power system. The host computer 120 is configured to send a test command to the test terminal 110. Upon receiving the test command, the test terminal 110 is configured to transmit a throttle signal and power-up / down signals to the drone under test, obtain power operation information and power supply information, determine the drone's aging performance based on the power operation information, and determine the drone's power-up / down performance based on the power supply information. The throttle signal and power-up / down signals are transmitted simultaneously from the same source, generated using the same signal generation rules, and have the same signal duration. The power operation information is operational data of the drone's electronic speed controller when operating based on the throttle signal, and the power supply information is power supply data of the drone's power supply when powered on or off based on the power-up / down signals.

[0026] Figure 2 This is a flow chart of the drone testing method provided by the embodiment of the present application. Figure 2 In some embodiments, the method includes but is not limited to steps S201 to S204.

[0027] Step S201: transmitting a throttle signal and an up / down power signal to the UAV to be tested.

[0028] The throttle signal and the power-up / down signals are transmitted simultaneously from the same source, generated using the same signal generation rules, and have the same duration. The throttle signal is the command signal that controls the speed of the electronically controlled drive motor. It can be implemented using PWM waveform encoding, which adjusts the duty cycle to control the power output. The power-up / down signals are the command signals that control the on / off state of the power system. They can be implemented using level-hopping signal encoding, which switches between high and low levels to control the power supply state.

[0029] As some examples, after receiving a test command from the host computer, the test terminal generates a throttle signal and an up / down power signal based on the same signal generation rules. The throttle signal and the up / down power signal have the same signal duration and are transmitted to the drone at the same time. The throttle signal acts on the drone's electronic speed controller, while the up / down power signal acts on the drone's power supply.

[0030] Step S202: Acquire power operation information and power supply information.

[0031] Power operation information refers to the drone's ESC operating data when it's operating based on a throttle signal. This information can include dynamic parameters like ESC output current and motor speed, collected via Hall effect sensors, and used to assess wear on power components.

[0032] Power supply information refers to the power supply data of the drone's power supply when it is powered on or off based on power-up and power-down signals. It can include parameters such as startup response time and voltage fluctuations, acquired through voltage and current sampling circuits to monitor power system stability.

[0033] As some examples, after transmitting the throttle signal and the up and down power signals, the test terminal obtains the power operation information and power supply information by obtaining the operating data of the electronic speed controller when it runs based on the throttle signal and the power supply data when the power supply is powered on or off based on the up and down power signals.

[0034] Step S203: determining the aging performance of the UAV based on the power operation information.

[0035] Step S204: determining the power-on and power-off performance of the drone based on the power supply information.

[0036] In actual application, the host computer sends a test command to the test terminal. Upon receiving the test command, the test terminal generates a throttle signal and power-up / down signals of the same duration based on the same signal generation rules and simultaneously transmits the throttle signal and power-up / down signals to the drone under test. During the test, the ESC drives the motor in response to the throttle signal, while the power supply performs power-up / down operations simultaneously. The drone's data acquisition module records real-time operating data from the ESC when operating in response to the throttle signal and power supply data from the power supply when powered on or off in response to the power-up / down signals. This information, known as power operation information and power supply information, is fed back to the test terminal by the drone. After obtaining this information, the test terminal determines the drone's aging performance based on the power operation information and the power supply performance based on the power supply information. For example, it compares the data to benchmark data under standard operating conditions to determine the drone's power system efficiency degradation rate and power supply system power-up / down reliability indicators. Therefore, in combination with testing the aging performance and power-on and power-off performance of the drone, the throttle signal and power-on and power-off signals are transmitted simultaneously from the same source, generated by the same signal generation rules and with the same signal duration during the test process, so that the control timing of the aging performance test and the power-on and power-off performance test are consistent, avoiding timing confusion caused by long-term testing and adverse effects on the test results, such as the throttle not returning to zero when power is off and online. The aging performance and power-on and power-off performance of the drone can be tested simultaneously for a long time, so that the test results can fit the actual usage conditions of the drone.

[0037] In some embodiments, before transmitting the throttle signal and the up / down electrical signals to the UAV to be tested, the method further includes: configuring the throttle signal and the up / down electrical signals based on a signal generation rule; and respectively allocating the throttle signal and the up / down electrical signals to corresponding signal transmission channels.

[0038] Signal generation rules refer to pre-defined signal parameter generation standards, which can be implemented using a mapping table between logical and physical signals. For example, a mapping between the duty cycle range and voltage amplitude range for the throttle logic signal is established to ensure that the signal parameters comply with the drone hardware interface specifications.

[0039] A signal transmission channel is an independent path for transmitting specific types of signals. This can be implemented using a multiplexer or frequency divider circuit. For example, a PWM output port can be assigned to the throttle signal, while a GPIO control port can be assigned to the power-up and power-down signals, thereby avoiding crosstalk during signal transmission.

[0040] During the test preparation phase, the pulse width modulation parameters of the throttle signal and the high and low level trigger conditions of the upper and lower power signals are first set through the configuration tool according to the communication protocol requirements between the ESC and the power supply. Subsequently, the throttle signal and the upper and lower power signals are configured based on the signal generation rules. The configured throttle signal is bound to the transmission channel corresponding to the ESC control port through the hardware interface, and the upper and lower power signals are bound to the transmission channel corresponding to the power management module. This achieves the isolation of different signal types on the physical transmission path and ensures the precise synchronization of signal timing during subsequent testing. Therefore, by unifying the signal generation rules and establishing a dedicated transmission channel, the impact of signal parameter deviation and path interference on the test results is eliminated, and the throttle signal and the upper and lower power signals are accurately matched at the physical layer, providing a reliable signal foundation for subsequent synchronization testing.

[0041] In some embodiments, transmitting a throttle signal and an up / down electrical signal to a drone to be tested includes: determining a throttle logic signal and an up / down electrical logic signal based on a test item to be executed; encoding the throttle logic signal and the up / down electrical logic signal based on a signal generation rule to obtain a throttle signal and an up / down electrical signal; transmitting a throttle signal to the drone's electronic regulator and transmitting an up / down electrical signal to the drone's power supply.

[0042] The test project refers to the joint testing requirements for the UAV's propulsion system and power supply system, which can specifically include a combination of simulated flight load testing and battery replacement testing to verify the system's ability to work together in complex scenarios.

[0043] The throttle logic signal is a sequence of commands that controls the speed of the electronically controlled motor. It's implemented using pulse-width modulation (PWM), with the pulse width parameter linearly proportional to the motor speed. The power-on / off logic signal is a sequence of commands that controls the power supply's on / off status. It's implemented using high- and low-level signals, with the level transition timing aligned with battery replacement.

[0044] The test items are pre-divided into multiple test phases, such as the takeoff phase, the hovering phase, and the landing phase. A corresponding throttle logic signal is generated for each phase, such as setting a continuously increasing throttle pulse width in the takeoff phase and setting a constant pulse width in the hovering phase. The power-on and power-off logic signals corresponding to the test phases are generated synchronously, such as triggering the power-off signal of the power supply after the hovering phase to simulate the battery replacement operation. The throttle logic signal and the power-on and power-off logic signals are encoded separately according to the signal generation rules, such as aligning the starting pulse width of the throttle logic signal with the rising edge of the power-on and power-off logic signals, so that the ESC receives the throttle signal to drive the motor while the power supply receives the power-on signal to maintain power supply. Finally, the encoded throttle signal is sent to the ESC interface, and the power-on and power-off signals are sent to the power supply. Therefore, through unified signal generation rules, the encoding synchronization of the throttle signal and the up and down electrical signals is achieved, so that the load operation of the electronic speed controller drive motor and the power on and off operation are accurately matched on the time axis. For example, when the motor reaches the maximum speed, the power is cut off synchronously to test the system response in the emergency power off scenario. The operating status of the electronic speed controller drive motor and the power supply status can simulate the collaborative working conditions in the battery replacement scenario in real flight. For example, the power switching operation is triggered when the power load reaches the peak, thereby accurately evaluating the system reliability of the UAV in complex usage environments.

[0045] In some embodiments, encoding the throttle logic signal and the up and down electrical logic signal based on the signal generation rules includes: dividing the throttle logic signal into multiple throttle logic sub-signals and dividing the up and down electrical logic signal into multiple up and down electrical logic sub-signals based on the test phase of the test item; encoding the starting pulse width duration and the ending pulse width duration of both the throttle logic sub-signal and the up and down electrical logic sub-signal according to the operating frequency of the throttle of the electronic regulation and the pulse width duration of the electronic regulation to obtain the throttle signal and the up and down electrical signal.

[0046] The throttle logic sub-signal and the power-up / down logic sub-signal refer to signal segments formed by dividing the throttle logic signal or the power-up / down logic signal according to a time series. Specifically, pulse width modulation technology can be used to segment the signal. Each sub-signal corresponds to a control instruction in a specific time window in the test phase.

[0047] During drone testing, the test phase is divided into multiple consecutive time windows. The throttle logic signal and the power-up / down logic signal are each segmented into sub-signal sequences corresponding to the number of test phases. The starting and ending pulse widths of each sub-signal are synchronously encoded based on the throttle operating frequency and pulse width duration of the ESC. For example, during the startup phase, a higher signal frequency is set to match the motor acceleration requirements. At this time, the starting pulse width of the power-up / down logic signal is aligned with the rising edge of the first pulse of the throttle sub-signal. During steady-state operation, the signal frequency is reduced and the pulse width remains constant. The ending pulse width of the power-up / down logic signal is synchronized with the falling edge of the last pulse of the throttle sub-signal. In this way, the operating state of the power system is precisely linked to the timing of the power-up / down logic signal. Therefore, through sub-signal division and pulse width synchronization encoding, the power control and power supply operations are overlapped on the time axis. For example, the up and down power signals are triggered before the throttle signal is completely ended, thereby reproducing the scenario of replacing the battery when the power is not completely cut off during actual use of the drone. During the test, the load changes of the power system and the power on and off operations can produce real mutual interference, such as the voltage fluctuation caused by the sudden power failure during the inertial rotation of the motor, thereby accurately evaluating the comprehensive performance of the drone under complex working conditions.

[0048] In a specific embodiment, based on the throttle characteristics of the ESC, the operating voltage of the PWM throttle is a high level (3.3V), the operating frequency of the PWM throttle is 400Hz, and the operating pulse width of the ESC is between 1000us and 2000us. Based on this characteristic, a signal encoding rule of 0 to 2500 is established, where 0 represents no high level (3.3V) output, 1 represents a high level (3.3V) lasting 1us within a signal cycle, and 2500 represents a continuous high level (3.3V) output. Figure 3 , based on the above signal encoding rules, the encoding is as follows Figure 3 The throttle signal and up and down electrical signals are shown.

[0049] In some embodiments, determining the aging performance of the drone based on the power operation information includes: comparing the operating data in the power operation information with the operating data in the preset power operation reference information, and determining the aging performance of the drone according to the comparison result of the operating data.

[0050] Power operation reference information refers to a pre-established set of operating data of the UAV under standard working conditions. It can be generated through the average value of multiple tests in a laboratory environment or a theoretical calculation model, and is used to characterize the baseline performance of the UAV when it is not aged.

[0051] During drone testing, power operation information is collected in real time and synchronously compared with power operation reference information. For example, during the continuous throttle signal input phase, the speed data generated by the ESC drive motor is compared with the standard speed at the same throttle opening in the reference information. If the real-time speed is lower than the standard value and the deviation exceeds a preset threshold, the motor is determined to be aging. Furthermore, by analyzing the degree of fit between the current fluctuation curves at different test stages and the reference curve, the performance degradation of the ESC's internal components can be identified. Thus, based on the multi-dimensional differences in operating data, the degree of aging of the drone's power system can be comprehensively judged. By dynamically comparing real-time operating data with preset reference data, it can not only reflect the performance degradation of the power system during continuous operation, but also capture the hidden damage to the motor and ESC caused by transient shocks caused by frequent power switching, making the aging assessment more accurate to real-world operating conditions.

[0052] In some embodiments, determining the power-on and power-off performance of the drone based on the power supply information includes: comparing the power supply data in the power supply information with the power supply data in the preset power supply reference information, and determining the power-on and power-off performance of the drone based on the power supply data comparison result.

[0053] Power supply reference information refers to a pre-established set of standardized power supply data, such as a stable power supply parameter range obtained through multiple tests in a laboratory environment, which serves as a benchmark for determining whether the actual power supply data is qualified.

[0054] When replacing a drone's battery, the power supply must be powered on to activate the system. During the test, voltage fluctuation curves and current peak values ​​are collected during the power supply startup phase. This data is compared item by item with pre-stored standard power supply parameters. For example, the actual voltage rise time is compared with a reference value for threshold determination. If the actual data exceeds the reference range, the power supply is judged to have poor contact or aging circuits, resulting in substandard power-on and power-off performance. Therefore, by synchronously collecting dynamic power supply data and comparing it with standardized parameters, the stability of the power supply under real-world operating conditions can be directly reflected, avoiding misjudgments caused by a single test environment.

[0055] In some embodiments, the drone testing method further includes: displaying the aging test results and power-on and power-off test results of the drone, and / or uploading the aging test results and power-on and power-off test results to a host computer in response to a received upload instruction.

[0056] After obtaining the aging test results and power-on / off test results, the test terminal displays them in real time, for example, by presenting a motor speed fluctuation curve and a power supply voltage stability curve in graphical form on the control panel. Alternatively, the test terminal packages the aging test results and power-on / off test results into a standardized format file and transmits them to a remote server or host computer software via a wireless communication module, facilitating subsequent batch data analysis and historical record tracing. Thus, by integrating the display module and communication module, the simultaneous visualization and remote transmission of multi-dimensional test data are achieved, making the testing process more closely aligned with the actual use scenario of drones, where frequent battery replacement is required.

[0057] See Figure 4 The present application also provides a drone testing device that can implement the above drone testing method. The device includes: The first module 401 is used to transmit a throttle signal and an up / down signal to the UAV to be tested; the throttle signal and the up / down signal are transmitted simultaneously from the same source, generated by the same signal generation rule, and have the same signal duration; The second module 402 is used to obtain power operation information and power supply information; the power operation information is the operation data of the UAV's electronic speed controller when it is running based on the throttle signal, and the power supply information is the power supply data of the UAV's power supply when it is powered on or off based on the power up and down signals; The third module 403 is used to determine the aging performance of the UAV based on the power operation information; The fourth module 404 is used to determine the power-on and power-off performance of the drone based on the power supply information.
