[0037] Example 1

[0038] like Figure 1 As shown, the present embodiment provides an integrated electric speed adjustment operation data recording system 10, including an electric speed adjustment main control module 100, a Flash storage module 200, an interface module 300, a display screen 400, a power management module 500, a fault detection module 600, a data compression module 700 and a data encryption module 800. Among them, the Flash storage module 200, the display screen 400, the power management module 500, the fault detection module 600, the data compression module 700 and the data encryption module 800 are respectively connected to the electric speed adjustment main control module 100. Specifically, the Flash storage module 200 is integrated on the PCB board where the electric speed adjustment main control module 100 is located, and is used to store data during the operation of the electric speed adjustment. The interface module 300 is connected to the Flash storage module 200, and is used to transmit the data stored in the Flash storage module 200 to an external device for analysis.

[0039] In this embodiment, the ESC main control module 100 uses an STM32 microcontroller. In this embodiment, the display screen 400 is used to display the data waveform of the last operation stage of the ESC. Specifically, the display screen 400 can be a small OLED display screen.

[0040] The power management module 500 is used to manage the power supply of the ESC to ensure that the integrity of the data record can be prioritized when the power is insufficient. The fault detection module 600 is used to detect the status of the Flash storage module 200 and the ESC main control module 100 in real time, and to issue an alarm when a fault is detected. The data compression module 700 compresses the data before storing it in the Flash storage module 200 to save storage space. Specifically, a data compression algorithm is implemented in the STM32 microcontroller to compress the collected data to save storage space. The data encryption module 800 encrypts the data stored in the Flash storage module 200 to ensure the security of the data. Specifically, the data in the Flash storage module 200 is encrypted by AES.

[0041] In this embodiment, the integrated electric speed control operation data recording system 10 further includes a remote access module 901, which allows remote users to access and read the data stored in the Flash storage module 200 through a network interface.

[0043] In this embodiment, the Flash storage module 200 uses a SPI Flash with a capacity of 1GB, and the interface module uses a serial port interface module. When the ESC is running, the MCU collects the voltage, current, speed and temperature data of the ESC in real time, and stores them in the Flash storage module 200 after data compression by the data compression module 700 and encryption by the data encryption module 800. When the ESC stops running, the ESC is connected to an external device through the serial port interface module, and the data is transmitted to the external device (for example: a computer or mobile device) through the serial port interface module for analysis and processing, and the analysis results are displayed in the form of charts.

[0044] Example 2

[0045] This embodiment adds a data visualization function based on the first embodiment. After the external device receives the data, when analyzing and processing the data, the trend of voltage, current, speed, temperature and other data over time is displayed in the form of a line graph using the Python programming language and the Matplotlib library, and interactive operations such as zooming in, zooming out, and panning of data points are provided, which facilitates the user to deeply analyze and understand the operating characteristics of the ESC.

[0046] Example 3

[0047] This embodiment is aimed at a large electric adjustment system, and uses a USB interface module to replace a serial port interface module to improve data transmission speed and compatibility. At the same time, in order to meet long-term data storage requirements, the capacity of the Flash storage module 200 is increased to 4GB.

[0051] When the ESC stops running, the data stored in the Flash storage module 200 is transmitted to an external device for analysis via the interface module 300 .

[0052] In this embodiment, before storing the data in the Flash storage module 200, the steps of compressing and encrypting the data are also included.
