[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] Example 1

[0038] Figure 1 This is a flowchart illustrating a fan calibration method provided in Embodiment 1 of the present invention. This method is applicable to calibrating the drive parameters of fans in electrical equipment. The method can be executed by a fan calibration device, which can be implemented in hardware and / or software and is generally integrated into a computer device.

[0039] like Figure 1 As shown, the fan calibration method provided in this embodiment may specifically include the following steps:

[0040] S101. Determine the calibration drive parameters that keep the fan speed in the electrical equipment at the target speed.

[0041] In existing technologies, for mass-produced electrical appliances, uniform drive parameters are typically used to control the fan speed. However, due to manufacturing processes and other factors, the fan speeds of different appliances may vary under the same drive parameters, resulting in inconsistent noise levels and impacting user experience. In this embodiment, each appliance is individually calibrated upon production to obtain the drive parameters that maintain the fan speed at a target speed; these are denoted as the calibration drive parameters. For example, the electrical appliance described in this embodiment is a device containing a fan, such as a car refrigerator.

[0042] In this embodiment, it can be assumed that when the fan speed reaches the corresponding target speed, the requirements for cooling effect and noise reduction can be met. The target speed can be determined experimentally. The target speed can be a specific value or a range. For example, the target speed can be set to 1200 rpm, or it can be set to 1200-1400 rpm. Preferably, when calibrating the electrical equipment one machine at a time, the fan speed accuracy can meet the 1% requirement. The driving parameters can specifically be the fan driving voltage or other quantities reflecting the driving force on the fan. For example, when controlling the speed using PWM technology, the driving parameter can be the duty cycle of the PWM signal; no specific limitation is made here.

[0043] For example, one specific implementation of calibrating electrical equipment could be to develop a host computer to perform individual calibration on each electrical device when it is taken offline. It should be noted that calibration can be performed by directly powering the fan or by writing drive parameters to the electrical device; the latter is more efficient. The calibration process can be described as follows: either by directly powering the fan or by writing drive parameters to the electrical device, obtain the current fan speed; if the current speed is not equal to the target speed, adjust the drive parameters and return to the step of writing drive parameters to the electrical device until the current fan speed is maintained at the target speed; obtain the drive parameters corresponding to the target speed as the calibration drive parameters.

[0044] S102. Write the calibration drive parameters into the memory of the electrical device.

[0045] In this embodiment, to prevent the loss of calibration drive parameters during subsequent software upgrades, the calibration drive parameters need to be written into a memory, preferably an electrically erasable programmable read-only memory (EEPROM). Since the electrical device is a Local Interconnect Network (LIN) controller, the calibration drive parameters can be written into the EEPROM using a specific frame method based on LIN communication principles. When the electrical device is turned on after being taken offline, the pre-stored calibration drive parameters can be directly read from the memory to control the fan speed based on these parameters.

[0046] It should be noted that each electrical appliance undergoes drive parameter calibration before leaving the production line, and the calibrated drive parameters are written into the appliance's memory. During actual operation, the appliance reads the calibrated drive parameters from its memory, and the appliance's controller then controls the fan speed according to these parameters.

[0047] The above technical solution involves calibrating each electrical device individually to determine the driving parameters that maintain the fan speed at the target speed. These calibrated driving parameters are then written into memory. Subsequent fan speed control based on these parameters ensures that the fan speed in each device remains at the target speed. Without adding any hardware, this calibration method addresses consistency issues during fan manufacturing, controls variations caused by mass production, controls fan noise, and improves the user experience.

[0048] Example 2

[0049] Figure 2 This is a flowchart illustrating another fan calibration method provided in Embodiment 2 of the present invention. This embodiment is a further optimization of the above embodiment. In this embodiment, the "determining the calibration drive parameters to keep the fan speed in the electrical device at the target speed" and the "writing the calibration drive parameters into the memory of the electrical device" are further optimized.

[0050] like Figure 2 As shown in the figure, this embodiment 2 provides a fan calibration method, which specifically includes the following steps:

[0051] S201. Write drive parameters to the electrical device and obtain the current speed of the fan in the electrical device.

[0052] In this embodiment, each piece of electrical equipment can be calibrated individually before it leaves the production line. Specifically, a developed computer device, such as a host computer, can be used to write drive parameters to the electrical equipment. Based on these drive parameters, the fan in the electrical equipment can be controlled to rotate, and the current fan speed can be obtained in real time and recorded as the current speed.

[0053] S202. If the current speed is not equal to the target speed, adjust the drive parameters and return to the step of writing drive parameters to the electrical device until the current speed of the fan is maintained at the target speed.

[0054] Specifically, the current fan speed is compared with the target fan speed. If the current fan speed is not equal to the target fan speed, it indicates that the fan speed controlled by the currently written drive parameters cannot meet the requirements for cooling effect or noise, and the drive parameters need to be adjusted. Then, the process returns to re-execute the steps of writing drive parameters to the electrical device and obtaining the current fan speed in the electrical device until the current fan speed is maintained at the target speed. If the current fan speed is less than the target fan speed, it indicates that the fan cooling effect is poor, and the drive parameters need to be increased to increase the fan speed; if the current fan speed is greater than the target fan speed, it indicates that the fan noise is high, and the drive parameters need to be decreased to decrease the fan speed.

[0055] S203. Obtain the drive parameters corresponding to the target speed as calibration drive parameters.

[0056] In this embodiment, the current speed of the fan is made equal to the target speed by adjusting the drive parameters. At this time, the drive parameters corresponding to the target speed are obtained as calibration drive parameters.

[0057] S204. Convert the calibration drive parameters into target data frames based on the local interconnection network communication protocol.

[0058] Considering that the electrical equipment is a LIN controller, in order to write the calibration drive parameters into the electrical equipment's memory, the calibration drive parameters can be converted into a specific frame based on the LIN communication protocol, denoted as the target data frame.

[0059] As a specific implementation method, the steps of converting calibration driving parameters into target data frames based on local interconnection network communication protocols can be optimized, including: constructing target data frames by combining calibration driving parameters, identifiers of computer devices used to send target data frames, and feature identification parameters used to represent calibration driving parameter association instructions according to local interconnection network communication protocols.

[0060] In this embodiment, a computer device is developed to send target data frames to an electrical appliance. The identifier of the computer device can be understood as the unique identifier of the master node in the LIN network communicating with the electrical appliance. For example, assuming the electrical appliance is calibrated based on a developed host computer, the host computer can be considered the master node in the LIN communication, and its ID is the identifier, such as 0x3B. The feature identification parameter used to represent the calibration drive parameter associated instruction can be understood as what instruction is associated with the calibration drive parameter. For example, the instruction could be to turn on the electrical appliance or adjust the cooling temperature. For instance, the feature identification parameter can be represented by the first four bytes as 55AA55AA, and the fifth byte as the calibration drive parameter. In this step, the calibration drive parameter, the identifier, and the feature identification parameter are combined according to the Local Area Network (LAN) communication protocol to form a specific frame, denoted as the target data frame.

[0061] The above technical solution specifies the steps for converting calibration drive parameters into target data frames to communicate with electrical equipment based on local interconnection network communication protocols.

[0062] S205. The target data frame is written into the memory of the electrical device using a local interconnection network communication protocol.

[0063] In this embodiment, the target data frame is written to the memory of the electrical device using LIN communication. For example, the target data frame can be written to an EEPROM located in the controller of the electrical device using LIN5 without slave nodes.

[0064] Understandably, when electrical equipment is not calibrated, the ideal speed corresponds to a 70% PWM duty cycle. Too high a PWM duty cycle results in excessive speed and noise, while too low a PWM duty cycle leads to poor cooling performance. Therefore, calibration is performed around this ideal 70% PWM duty cycle speed, meaning that even with an error margin of 40%-100%, it can be calibrated to the ideal 70% PWM duty cycle. Furthermore, the calibrated fan speed is not erased after an online (Over-The-Air, OTA) update.

[0065] The above technical solution specifies the steps for calibrating a fan in an electrical appliance and writing the calibration drive parameters into memory. By writing the drive parameters to the electrical appliance and obtaining the fan's current speed, the drive parameters needed to reach the target speed are determined, thus calibrating the electrical appliance. The calibration drive parameters are then written to memory via a local interconnect network communication protocol. Without adding any hardware, only software calibration is used for optimization, achieving noise control of the cooling fan, solving the problem of inconsistent fan speeds under the same voltage due to manufacturing inconsistencies, reducing the impact of cooling fan noise on users, and improving the user experience.

[0066] Example 3

[0067] Figure 3 This is a flowchart illustrating a fan speed control method provided in Embodiment 3 of the present invention. This method is applicable to situations where the fan speed in electrical equipment is controlled. This method can be executed by a fan speed control device, which can be implemented in hardware and / or software and is generally integrated into the electrical equipment.

[0068] like Figure 3 As shown, the fan speed control method provided in this embodiment three may specifically include the following steps:

[0069] S301. When the electrical equipment is powered on, the calibration drive parameters of the electrical equipment are read from the memory of the electrical equipment.

[0070] In this embodiment, the calibration drive parameters are determined using the fan calibration method of Embodiment 1 or Embodiment 2.

[0071] In this embodiment, each electrical appliance is individually calibrated when it is taken offline to obtain calibration drive parameters that maintain the fan speed of the appliance at a target speed, and these calibration drive parameters are written into the appliance's memory. Each appliance's memory stores the calibration drive parameters for its own fan. When the appliance is powered on, its calibration drive parameters are read from its memory. Preferably, the memory is an EEPROM.

[0072] S302. The fan of the electrical equipment is controlled by calibrated drive parameters so that the fan speed is maintained at the target speed.

[0073] In this embodiment, the target speed can be specifically understood as the fan speed that meets the requirements for cooling effect and noise reduction. Since the calibration drive parameters are pre-calibrated for this electrical device, and these calibration drive parameters have a corresponding relationship with the target speed of the fan, controlling the fan of the electrical device using the calibration drive parameters can keep the fan speed at the target speed.

[0074] The above technical solution involves calibrating each electrical device individually to determine the drive parameters that maintain the fan speed at the target speed, and then writing these calibrated drive parameters into a memory. When the electrical device is powered on, the fan speed is controlled based on these calibrated drive parameters, ensuring the fan speed remains at the target speed. This achieves control over the cooling effect and noise level of the fan, improving the user experience.

[0079] The above technical solution involves calibrating each electrical device individually to determine the driving parameters that maintain the fan speed at the target speed. These calibrated driving parameters are then written into memory. Subsequent fan speed control based on these parameters ensures that the fan speed in each device remains at the target speed. Without adding any hardware, this calibration method addresses consistency issues during fan manufacturing, controls variations caused by mass production, controls fan noise, and improves the user experience.

[0080] Optionally, the parameter determination module 41 is specifically used for:

[0081] Write drive parameters to electrical equipment and obtain the current fan speed in the electrical equipment;

[0082] If the current speed is not equal to the target speed, adjust the drive parameters and return to the step of writing drive parameters to the electrical device until the current speed of the fan is maintained at the target speed.
