Description

TECHNICALFIELD

The present application relates to the technical field of signal processing, and in particular, to a method, device and system for controlling a linear motor of an electronic atomizer, and an electronic atomizer.

BACKGROUND

An electronic atomizer may control a linear motor through output of a driving chip to achieve a better motor vibration effect. The driving chip has two control modes: a real-time transport protocol (RTP) mode and a random access memory (RAM) mode. In the RTP mode, any form of vibration waveforms may be outputted. In the current market, the RTP mode is used in almost all electronic products with linear motors. More hardware resources are generally required in the RTP mode. However, due to limited hardware resources of electronic atomizer products, most driving chips of electronic atomizers can only use the RAM mode to drive linear motors. However, in the RAM mode, only simple waveforms instead of rich vibration waveforms can be generated, causing vibration feedback of the electronic atomizer products to be in a relatively simple form.
During the implementation, the inventor finds that the conventional art has at least the following problems. The existing electronic atomizer uses the RAM mode to drive the linear motor to vibrate, leading to problems of a single vibration form and impossible generation of rich vibration waveforms.

As described in the background, the electronic atomizer in the prior art uses the RAM mode to drive the motor to vibrate, which has the problems of impossible generation of rich vibration waveforms and poor practicability. Through the inventor's research, it is found that any form of rich vibration waveforms can be outputted in the RTP mode. However, due to fewer hardware resources of the electronic atomizer and a single-task operation nature of the controller thereof, other operations cannot be performed at the same time when the controller writes data into the driving module.
Based on the above reasons, the present invention provides a solution of using a DMA function of the controller to control the driving module through the RTP mode.
In one embodiment, as shown in FIG. 1, a method for controlling a linear motor of an electronic atomizer is provided. The method is applied to a controller including a DMA unit, and may include the following steps.
In step 202, a play instruction is sent to a driving module of the electronic atomizer, the play instruction including a current vibration waveform data packet, the play instruction being used for instructing the driving module to play the vibration waveform data packet to drive the linear motor of the electronic atomizer to vibrate, the vibration waveform data packet including a vibration waveform of vibration waveform data matching a current vibration mode.
In step 204, if an interrupt signal fed back by the driving module is received, a play instruction including a next vibration waveform data packet is sent to the driving module.
The driving module may be a driving chip. Hardware configuration of the driving chip may be implemented by an I2C (inter-integrated circuit) bus, which is a two-line serial bus. The controller may be a single-chip microcomputer including a DMA unit.
During daily use of the electronic atomizer, the electronic atomizer may be operated correspondingly to trigger vibration feedback of the electronic atomizer, so that people can more intuitively grasp use feedback of the electronic atomizer during the use. Tactile (vibration) feedback is a new feedback mode which is different from auditory feedback and visual feedback. The vibration feedback not only enables the product to communicate with users flexibly in noisy and light-limited environments, but also improves monotonous operation experience caused by a current flat-touch-based operation manner. That is, the vibration feedback of the electronic atomizer not only conveys information to the users, but also enhances user experience.
A vibration mode may be divided into short vibration, fade-in vibration or fade-out vibration according to usage scenarios. Different vibration waveforms may bring different tactile effects to the users (such as Click, Pulse, Bump, Ramp up, Ramp down and other tactile effects, among which the Click vibration effect may have different vibration intensity such as strong, medium, weak, etc., a Click vibration duration may be short, long, longer, or other different time periods, and the different effects depend on different driving voltages and driving time). Different vibration modes in different scenarios can improve the users' comfort of use. For example, when a cartridge of the electronic atomizer is inserted and removed, the electronic atomizer may give a short vibration feedback, or when the users smoke the electronic atomizer, the vibration of the electronic atomizer may fade in until the users stop smoking the electronic atomizer. Rich vibration feedback enables the users to more intuitively obtain current usage feedback of the electronic atomizer, improving the users' comfort of use and practicability.
Specifically, a play instruction including a current vibration waveform data packet is sent to the driving module of the electronic atomizer, the vibration waveform data packet includes a vibration waveform of vibration waveform data matching a current vibration mode, and the vibration waveform data in different vibration modes may vary. The play instruction may instruct the driving module to play, in real time, the vibration waveform in the vibration waveform data packet received, so as to drive the linear motor of the electronic atomizer to vibrate correspondingly according to the vibration waveform matching the current vibration mode, so that the users can intuitively feel the vibration feedback under different usage scenarios. Thus, according to the present application, the driving module is instructed to immediately drive the linear motor to perform vibration of the vibration waveform of the vibration waveform data matching the current vibration mode in the case of receiving the play instruction while the play instruction including the current vibration waveform data packet is sent to the driving module.
Moreover, if an interrupt signal (INPT signal) fed back by the driving module is received, indicating that the driving module has played out the vibration waveform of the vibration waveform data matching the current vibration mode in the current vibration waveform data packet, a play instruction including a next vibration waveform data packet is sent to the driving module, so as to instruct the driving module to immediately play, in real time in the case of receiving the next vibration waveform data packet, a vibration waveform of vibration waveform data matching the current vibration mode in the next vibration waveform data packet to control the linear motor to continue the play until the vibration waveform data matching the current vibration mode is played out.
According to the present application, vibration waveform data matching the current vibration mode can be provided, and different vibration modes correspond to different vibration waveform data, so that the electronic atomizer can output rich vibration waveforms in a manner of writing data simultaneously with vibrating in the case of fewer hardware resources. In this way, the vibration waveform data requires a large storage space. Therefore, in the present application, vibration waveforms in the vibration waveform data are successively sent to the driving module of the electronic atomizer in the form of data packets. That is, in the present application, the controller including the DMA unit sends a play instruction including a current vibration waveform data packet to the driving module, so as to instruct the driving module to play the vibration waveform data packet to drive the linear motor of the electronic atomizer to vibrate correspondingly according to the vibration waveform data matching the current vibration mode, and in the case of receiving the interrupt signal fed back by the driving module, a play instruction including a next vibration waveform data packet is sent to the driving module to control the linear motor to continue the play, so as to output rich vibration waveforms in a manner of writing data simultaneously with vibrating in the case of fewer hardware resources, so that the linear motor brings a richer vibration effect, and practicability and user experience are greatly improved.
In one embodiment, the vibration waveform data is RTP mode vibration waveform data.
The step 202 where the play instruction is sent to the driving module of the electronic atomizer may include: sending the play instruction to the driving module by I2C-DMA when a vibration event of the electronic atomizer occurs currently.
The vibration event of the electronic atomizer is an event that requires feedback vibration of the electronic atomizer, such as insertion and removal of the cartridge of the electronic atomizer or a user's smoking of the electronic atomizer. Under different usage scenarios, different vibration events of the electronic atomizer may be triggered, which correspond to different vibration modes.
The RTP mode vibration waveform data in the present application may include any form of vibration waveforms, which may include vibration waveforms such as a harmonic vibration waveform, a periodic vibration waveform, a composite vibration waveform, a damped vibration waveform, a sinusoidal scanning waveform, a narrow-band random waveform, and a broadband random waveform, and may also include a waveform superimposed by various forms of vibration waveforms. Since data is written into the driving module in the RTP mode, a size (more than hundreds of k bytes) of the vibration waveform data in the RTP mode is generally much larger than a storage space of the SRAM of the driving module. Therefore, the RTP mode vibration waveform data can be written into the driving module in blocks.
Specifically, when the vibration event of the electronic atomizer occurs currently, the play instruction including the current vibration waveform data packet may be sent to the driving module of the electronic atomizer by I2C-DMA. The vibration waveform data packet includes a vibration waveform of the RTP mode vibration waveform data matching the current vibration mode. That is, the vibration waveform included in the current vibration waveform data packet sent to the driving module matches the current vibration mode. Vibration waveforms of the RTP mode vibration waveform data under different vibration modes may vary, so as to intuitively feel vibration feedback under different usage scenarios when the vibration event of the electronic atomizer occurs. The play instruction is used for instructing the driving module to immediately play the vibration waveform data packet in the case of receiving the play instruction including the current vibration waveform data packet, so as to drive the linear motor of the electronic atomizer to vibrate according to the vibration waveform matching the current vibration mode. Thus, in the present application, when the vibration event of the electronic atomizer occurs currently, the linear motor immediately performs the corresponding vibration while the vibration waveform data packet including the vibration waveform of the RTP mode vibration waveform data matching the current vibration mode is sent to the driving module, which realizes a control process of writing data simultaneously with vibrating, and the RTP mode vibration waveform data can provide rich vibration waveforms corresponding to the current vibration mode.
If the interrupt signal (INPT signal) fed back by the driving module is received, it indicates that the driving module has played out the vibration waveform of the RTP mode vibration waveform data in the vibration waveform data packet. Therefore, a play instruction including a next vibration waveform data packet may be sent to the driving module by I2C-DMA, so as to instruct the driving module to play the next vibration waveform data packet to control the linear motor to continue vibrating.
In the present application, when the vibration event of the electronic atomizer occurs currently, the play instruction including the current vibration waveform data packet is sent to the driving module of the electronic atomizer by I2C-DMA, so as to instruct the driving module to play the vibration waveform data packet to drive the linear motor of the electronic atomizer to vibrate correspondingly. The vibration waveform data packet includes a vibration waveform of RTP mode vibration waveform data matching the current vibration mode. Under different vibration modes, the present application may also provide corresponding different RTP mode vibration waveform data. Thus, in the present application, rich vibration waveforms can be outputted in the RTP mode of writing data simultaneously with vibrating in the case of fewer hardware resources of the electronic atomizer, which greatly improves practicability and user experience.
In one embodiment, prior to the step 202 where the play instruction is sent to the driving module of the electronic atomizer, the method may include: resetting the driving module, and if a size of the vibration waveform data is larger than a storage space of an SRAM of the driving module, segmenting and packaging the vibration waveform data sequentially to obtain a number of vibration waveform data packets each with a size smaller than the storage space of the SRAM.
The SRAM of the driving module is configured to store the RTP mode vibration waveform data.
In a specific example, prior to the step of resetting the driving module, the method may include: initializing I2C-DMA configuration.
Specifically, prior to the vibration event of the electronic atomizer, I2C-DMA configuration may be initialized and interruption may be configured. The interruption is configured to define ports of the driving module for data input and output. The I2C-DMA configuration is initialized to ensure normal operation of a subsequent data processing process. When the vibration event of the electronic atomizer occurs currently, the driving module can be reset. The storage space of the SRAM of the driving module is generally 3k bytes, while the RTP mode vibration waveform data is generally more than hundreds of k bytes, which is much larger than the storage space of the SRAM. Therefore, a vibration waveform of the RTP mode vibration waveform data is required to be written into the driving module in blocks. That is, if a size of the RTP mode vibration waveform data matching the current vibration mode is larger than the storage space of the SRAM of the driving module, the RTP mode vibration waveform data matching the current vibration mode is segmented and packaged sequentially to obtain a number of vibration waveform data packets. Each vibration waveform data packet includes a corresponding partial vibration waveform of the RTP mode vibration waveform data, and a size of each vibration waveform data packet is smaller than the storage space of the SRAM. Thus, after the driving module plays out part of the vibration waveform in the RTP mode vibration waveform data in the current vibration waveform data packet, a play instruction including a next vibration waveform data packet is sent to the driving module to instruct the driving module to the following partial vibration waveform in the RTP mode vibration waveform data in the next vibration waveform data packet in order. Since a speed at which data is written into the driving module is much higher than a speed at which the driving module plays the vibration waveform, the linear motor can continue the corresponding vibration according to the vibration waveform of the RTP mode vibration waveform data matching the current vibration mode.
In the present application, the RTP mode vibration waveform data is segmented and packaged to obtain a number of vibration waveform data packets, the RTP mode vibration waveform data is written into the driving module in blocks, and the driving module is instructed to control the linear motor to vibrate correspondingly while the data is written into the driving module. Moreover, when the current vibration waveform data packet is played out, the driving module may be further instructed according to the play instruction including the next vibration waveform data packet to continue to play a vibration waveform in the next vibration waveform data packet, so that the linear motor continues to vibrate, and rich vibration waveforms can still be outputted in the case of limited hardware resources of the electronic atomizer, thereby improving practicability and users' comfort of use.
In one embodiment, the electronic atomizer linear motor control method may further include: outputting a vibration stop instruction if the interrupt signal is received after all the vibration waveform data packets are sent to the driving module, the vibration stop instruction being used for instructing the driving module to control the linear motor to stop vibrating.
Specifically, after the vibration waveform data packets obtained by segmenting and packaging the RTP mode vibration waveform data are sent to the driving module, if an interrupt signal fed back by the driving module is received, it indicates that the SRAM of the driving module has played out the vibration waveform of the RTP mode vibration waveform data matching the current vibration mode included in the vibration waveform data packets. That is, the driving module has played out the vibration waveform of the RTP mode vibration waveform data, and a vibration stop instruction can be outputted to the driving module to cause the linear motor to stop vibrating. That is, the linear motor has completed the corresponding vibration in the current vibration mode. For example, in the case of insertion and removal of the cartridge of the electronic atomizer, the linear motor feeds back a short vibration, and stop vibrating when the vibration waveform of the RTP mode vibration waveform data matching the current vibration mode is played out. When the electronic atomizer is smoked, the linear motor may feed back a vibration with fade-in vibration intensity, and stop vibrating when the smoking of the electronic atomizer is stopped. The matched RTP mode vibration waveform data may vary in different vibration modes, and the linear motor may also vibrate in different manners, so as to provide rich vibration feedback for the electronic atomizer and improve practicability and comfort of use.
In a specific example, if the size of the RTP mode vibration waveform data packet is smaller than the storage space of the SRAM of the driving module, the RTP mode vibration waveform data may not be segmented, and the RTP mode vibration waveform data may be directly sent to the SRAM of the driving module as a vibration data packet. Moreover, when an interrupt signal fed back by the driving module is received, a vibration stop instruction is outputted to instruct the driving module to control the linear motor to stop vibrating.
Based on the above, in the present application, when a vibration event of the electronic atomizer occurs currently, the RTP mode vibration waveform data in the storage space of the SRAM is segmented and packaged sequentially to obtain a number of vibration waveform data packets, and the play instruction including a current vibration waveform data packet is sent to the driving module by I2C-DMA. The play instruction is used for instructing the driving module to play the vibration waveform data packet to drive the linear motor to vibrate correspondingly. Moreover, when an interrupt fed back by the driving module is received, a play instruction including a next vibration waveform data packet is sent to the driving module by I2C-DMA, so that the remaining vibration waveform of the RTP mode vibration waveform data can be successively and continuously played in order, achieving continued vibration of the linear motor and a driving process of writing data simultaneously with vibrating in the RTP mode. In the present application, rich vibration waveforms can be outputted in the RTP mode in the case of fewer hardware resources of the electronic atomizer. The present application has high practicability and can greatly improve the users' comfort of use.
In one embodiment, as shown in FIG. 2, a method for controlling a linear motor of an electronic atomizer applied to a driving module of an electronic atomizer is provided. The method may include the following steps.
In step 302, in a case where a play instruction including a current vibration waveform data packet and sent by a controller of the electronic atomizer including a DMA unit is received, the vibration waveform data packet is played to drive the linear motor of the electronic atomizer to vibrate, the vibration waveform data packet including a vibration waveform of vibration waveform data matching a current vibration mode.
In step 304, the vibration waveform data packet is cleared if the vibration waveform data packet is played out, and an interrupt signal is fed back to the controller, the interrupt signal being used for instructing the controller to send a play instruction including a next vibration waveform data packet.
Specifically, in a case where a play instruction sent by a controller of the electronic atomizer including a DMA unit is received, the current vibration waveform data packet included in the play instruction is played to drive the linear motor of the electronic atomizer to vibrate correspondingly according to a vibration waveform of RTP mode vibration waveform data matching the current vibration mode included in the vibration waveform data packet, which realizes a driving process of writing data simultaneously with vibrating in an RTP mode. In a case where the vibration waveform data packet is played out, the SRAM is cleared, that is, the vibration waveform data packet in the SRAM is cleared, and an interrupt signal is fed back to the controller. The interrupt signal is used for instructing the controller to send a play instruction including a next vibration waveform data packet, so as to ensure continued vibration of the linear motor.
Based on the above, in the present application, in a case where the play instruction including the current vibration waveform data packet is received, the vibration waveform of the RTP mode vibration waveform data matching the current vibration mode included in the vibration waveform data packet is immediately played to drive the linear motor to vibrate, which realizes a driving process of writing data simultaneously with vibrating in the RTP mode, and in a case where the vibration waveform data packet is played out, an interrupt signal is fed back to the controller to instruct the controller to send a play instruction including a next vibration waveform data packet, so as to drive the linear motor to continue to vibrate according to the vibration waveform of the RTP mode vibration waveform data matching the current vibration mode. In the present application, the RTP mode may be adopted to drive the linear motor to vibrate in the case of fewer hardware resources of the electronic atomizer, so as to generate rich vibration waveforms, thereby providing users of the electronic atomizer with rich vibration feedback in different usage scenarios, and greatly improving practicality and comfort of use.

The steps or stages may be performed in turn or alternately with other steps or at least part of the steps or stages of other steps, rather than being necessarily performed sequentially.
In one embodiment, as shown in FIG. 3, a device for controlling a linear motor of an electronic atomizer is provided, which may include a first output module 110 and a second output module 120.
The first output module 110 is configured to send a play instruction to a driving module of the electronic atomizer, the play instruction including a current vibration waveform data packet, the play instruction being used for instructing the driving module to play the vibration waveform data packet to drive the linear motor of the electronic atomizer to vibrate, the vibration waveform data packet including a vibration waveform of vibration waveform data matching a current vibration mode.
The second output module 120 is configured to send, if an interrupt signal fed back by the driving module is received, a play instruction including a next vibration waveform data packet to the driving module.
In one embodiment, the electronic atomizer linear motor control apparatus may further include a reset module configured to reset the driving module, and if a size of the vibration waveform data is larger than a storage space of an SRAM of the driving module, segment and package the vibration waveform data sequentially to obtain a number of vibration waveform data packets each with a size smaller than the storage space of the SRAM.
In one embodiment, the electronic atomizer linear motor control apparatus may further include a third output module configured to output a vibration stop instruction if the interrupt signal is received after all the vibration waveform data packets are sent to the driving module, the vibration stop instruction being used for instructing the driving module to control the linear motor to stop vibrating.

Specific limitations on the electronic atomizer linear motor control apparatus may be obtained with reference to the limitations on the electronic atomizer linear motor control method hereinabove. Details are not described herein. The modules in the foregoing electronic atomizer linear motor control apparatus may be implemented entirely or partially by software, hardware, or a combination thereof. The above modules may be built in or independent of a processor of a computer device in a hardware form, or may be stored in a memory of the computer device in a software form, so that the processor invokes and performs operations corresponding to the above modules. It is to be noted that the division of the modules is merely schematic, which is merely a logical function division and may be another division in actual implementation.
In one embodiment, as shown in FIG. 4, a system for controlling a linear motor of an electronic atomizer (also shown as electronic atomizer linear motor control system) is provided, which may include: a driving module, a linear motor, and a controller including a DMA unit.
The driving module is connected to the controller and the linear motor respectively.
The controller is configured to perform the method for controlling the linear motor of the electronic atomizer described above, and/or the driving module is configured to perform the method for controlling the linear motor of the electronic atomizer described above.
In one example, the controller may be a single-chip microcomputer with a DMA function.
The driving module may be a driving chip. Hardware configuration of the driving chip may be implemented by an I2C bus.
Specifically, when a microcontroller unit (MCU) of the single-chip microcomputer writes the RTP mode vibration waveform data into the driving chip through the RTP mode (by writing data simultaneously with vibrating), due to a single-task operation nature of the single-chip microcomputer, the MCU of the single-chip microcomputer cannot perform other operations at the same time. Thus, in the present application, the DMA unit of the single-chip microcomputer is used to write the RTP mode vibration waveform data into the SRAM of the driving chip by I2C-DMA, the RTP mode vibration waveform data is played in real time, and the play is stopped when the writing of the data is stopped. During the vibration of the linear motor, the MCU of the single-chip microcomputer may not be affected by the writing of data into the driving chip through the DMA, and may perform other operations at the same time, so as to generate rich vibration waveforms in the case of fewer hardware resources of the electronic atomizer.
In one specific example, as shown in FIG. 5, after the electronic atomizer is powered on, I2C-DMA configuration is initialized. When a vibration event of the electronic atomizer occurs currently, for example, in the case of current insertion and removal of the cartridge of the electronic atomizer, the single-chip microcomputer may reset the driving chip, and configure interruption to define ports for data transmission. The single-chip microcomputer acquires the RTP mode vibration waveform data matching the current vibration mode. If the size of the RTP mode vibration waveform data is larger than the storage space of the SRAM of the driving chip, the single-chip microcomputer writes the RTP mode vibration waveform data into the SRAM in blocks. That is, the single-chip microcomputer segments and packages the RTP mode vibration waveform data sequentially to obtain a number of vibration waveform data packets, and send the play instruction including the current vibration waveform data packet to the driving chip by I2C-DMA. The driving chip, in the case of receiving the play instruction by I2C-DMA, immediately plays the vibration waveform data package, and controls the linear motor to vibrate correspondingly based on an RTP vibration waveform of the RTP mode vibration waveform data matching the current vibration mode included in the vibration waveform data packet. If the driving chip plays out the vibration waveform data packet, the vibration waveform data packet of the SRAM is cleared. An interrupt signal is fed back to the single-chip microcomputer in a case where the SRAM is cleared. When receiving the interrupt signal fed back by the driving chip, the single-chip microcomputer sends a play instruction including a next vibration waveform data packet to the driving chip by I2C-DMA. When receiving the play instruction including the next vibration waveform data packet, the driving chip drives the linear motor to continue to vibrate according to a vibration waveform in the next vibration waveform data packet, data writing simultaneously with vibrating are repeated until the single-chip microcomputer sends the vibration waveform data packets to the driving chip. The driving chip feeds an interrupt signal back to the single-chip microcomputer when playing out the final vibration waveform data packet, and the single-chip microcomputer outputs a vibration stop instruction to the driving chip when receiving the interrupt signal. The driving chip receives the vibration stop instruction and controls the linear motor to stop vibrating.
In one embodiment, the electronic atomizer linear motor control system may further include an RST rest driving chip and an I2C bus.
The RST rest driving chip is connected to the controller and the driving module respectively.
The controller is connected to the driving module through the I2C bus.
The linear motor is connected to an HDP pin of the driving module and an HDN pin of the driving module respectively.
As shown in FIG. 6, the I2C bus may include an I2C-serial clock line (SCL) line and an I2C-serial data (SDA) line.
Specifically, the single-chip microcomputer may reset the driving chip through the RST reset driving chip, and send a play instruction including a current vibration waveform data packet to the driving chip through the I2C bus. The driving chip, when receiving the play instruction including the current vibration waveform data packet, plays the current vibration waveform data packet, and drives the linear motor of the electronic atomizer to vibrate through the HDP pin and the HDN pin. When the current vibration waveform data packet is played out, the driving chip feeds an INPT signal (interrupt signal) back to the single-chip microcomputer. The single-chip microcomputer, when receiving the INPT signal, sends a play instruction including a next vibration waveform data packet to the driving chip through the I2C bus, until the interrupt signal fed back by the driving chip is received after the single-chip microcomputer sends the vibration waveform data packets to the driving chip. Then, a vibration stop instruction is sent to the driving chip through the I2C bus. The driving chip, when receiving the vibration stop instruction, controls the linear motor to stop vibrating through the HDP pin and the HDN pin.
Based on the above, in the present application, the RTP mode vibration waveform data is written into the SRAM of the driving module by I2C-DMA through the controller including a DMA unit, so that the driving module plays the waveform in real time to drive the linear motor to vibrate correspondingly according to the written RTP mode vibration waveform data. During the vibration of the linear motor, the controller can continue other operations without being affected by the writing of data into the driving module through the DMA. In the case of fewer hardware resources of the electronic atomizer, rich vibration waveforms are outputted in the RTP mode, so as to provide rich vibration feedback for users in various scenarios of using electronic atomizer, and enable the users to intuitively feel a use state of the electronic atomizer, which greatly improves practicability and comfort of use.
In one embodiment, as shown in FIG. 7, an electronic atomizer is provided, including the system for controlling the linear motor of the electronic atomizer described above.
The electronic atomizer in the present application can generate rich vibration waveforms in the RTP mode in the case of fewer hardware resources. For example, in the case of insertion and removal of the cartridge of the electronic atomizer or smoking of the electronic atomizer, different vibration feedback is triggered, so that the users can more intuitively understand the use of the electronic atomizer, and the practicality and comfort are greatly enhanced.
