Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

First, several nouns to which the present application relates are explained.

The filter capacitor is an energy storage device which is arranged at two ends of a rectifying circuit and used for reducing alternating current ripple coefficients and improving high-efficiency smooth direct current output. The filter circuit requires the energy storage capacitor to have larger capacitance.

A Micro Control Unit (MCU), also called a Single Chip Microcomputer (Single Chip Microcomputer) or a Single Chip Microcomputer (MCU), is a Chip-level computer formed by appropriately reducing the frequency and specification of a Central Processing Unit (CPU), and integrating peripheral interfaces such as a memory, a counter (Timer), a USB, an a/D converter, a UART, a PLC, a DMA, and the like, and even an LCD driving circuit on a Single Chip, and performing different combination control for different applications.

Fig. 1 shows a method for controlling a blower according to an embodiment of the present invention, which is suitable for a device having a high-speed motor, where the high-speed motor control application generally has a filter capacitor with a relatively large capacity, and after the device is turned off, a part of electric energy is stored in the filter capacitor and is supplied to an MCU to continue to operate for a period of time. The method comprises at least the following steps:

step 101, receiving a blower closing signal, wherein the blower closing signal is used for stopping the blower.

Step 102, detecting whether a power failure task exists or not, and executing the power failure task when detecting that the power failure task exists.

The power-down task is a task which cannot be executed when the blower is started, and if the task is executed when the blower is started, interference on a high-speed time sequence of motor driving can be caused, and then some error results can be caused. In this embodiment, the power-down task includes a braking task, a flash writing task, and others. For example, the Flash write process needs to shut down all interrupts of other components, and if an error occurs in the process, the operation of a high-speed motor may be disordered, and even the Flash write operation may cover a normal rom program body, which may cause unpredictable results. Indeed, in other embodiments, the power-down task may be other tasks, which are not specifically limited herein and are determined according to actual situations.

Optionally, the power-down tasks are stored in the power-down file in a queue row manner, so that after one power-down task is executed, the next power-down task is executed again. Indeed, in other embodiments, the power-down task may also be stored in the power-down task in other driving modes, which is determined according to actual situations and is not specifically limited herein.

Optionally, the method further comprises:

acquiring the current time length;

and when the current time length is longer than the preset time length, stopping executing the power failure task. And when the time length of the time period is greater than the preset time length after receiving the blower closing signal for a period of time, stopping executing the rest power-down task. Specifically, the preset time duration is a time duration from the discharge of the filter capacitor to the end of the discharge of the filter capacitor.

In summary, the following steps: by receiving a blower turn-off signal, the blower turn-off signal is used to cause the blower to stop operating; and then detecting whether a power-down task exists or not, and executing the power-down task when detecting that the power-down task exists, so that the influence on the driving process of the blower caused by the execution of some tasks when the blower is started is avoided. The electric energy stored in the filter capacitor is reasonably utilized, some power-down tasks are executed before the discharge of the filter capacitor is finished after the blower is turned off, and the influence of the power-down tasks on the motor driving process is reduced.
