- a method for parameterized description of motor electrical signals is provided, which specifically includes the following steps:
- Step 102 Acquire motor electrical signal data, where the motor electrical signal data is electrical signal combined data.
- the electrical signal combination data refers to the electrical signal data that can be used directly by the motor.
- the motor uses different electrical signal combination data, it can output the corresponding vibration form through the driving chip.
- Step 104 Read each segment of the electrical signal included in the electrical signal combination data, and record the start time point and the end time point of reading each segment of the electrical signal.
- the electrical signal combination data includes different types of electrical signals. Record and read the start time point and end time point of each segment of electrical signal to determine the type of each segment of electrical signal.
- Step 106 Determine the type of each segment of the electrical signal according to the start time point and the end time point of each segment of the electrical signal.
- the duration of each segment of the electrical signal is obtained by calculating and reading the start time and end time of each segment of the electrical signal, so as to determine the type of the electrical signal according to the duration of each segment of the electrical signal.
- Step 108 Acquire a description parameter of each electrical signal according to the type of each electrical signal.
- Step 110 Obtain a preset parameter description template, fill the description parameters of each segment of the electrical signal into the preset parameter description template for storage and record, and obtain a combination description parameter corresponding to the electrical signal combination data.
- the parameter description template may be an HPDE (Haptic Pattern Description) description template, and corresponding description parameters need to be filled in for different types of electrical signals. For example, for short signals, the description parameters are filled in the HPDE description template.
- Type identifies the type of electrical signal
- PREBAKED and ENVELOPE correspond to short signal and long signal respectively, and set corresponding values for each type of signal parameter.
- Step 112 Generate a vibration signal for driving the motor to vibrate according to the combined description parameters.
- the short signal in the combination description parameter when the short signal in the combination description parameter needs to be used, the short signal name can be used as an index, and the corresponding short signal can be indexed in the effect library.
- the description parameter corresponding to the long signal can be obtained and combined with the signal generation algorithm to approximate the long signal.
- the above-mentioned method for parameterized description of motor electric signals is to read the combined data of the electric signals, and determine the type of each electric signal according to the start time point and the end time point of each electric signal in the electric signal combined data. Then according to the type of each electrical signal, the description parameters of each electrical signal are obtained accordingly. Finally, by filling the description parameters of each segment of the electrical signal into the preset parameter description template, the combined description parameter corresponding to the combined data of the electrical signal is obtained.
- the embodiment of the present invention describes the electrical signal combination data by describing the parameters, which can avoid the direct exposure of the electrical signal data, and can play a certain protective effect on the electrical signal. At the same time, for long-signal electrical signals, the corresponding description parameters can be restored to electrical signals in real time during use, so the storage method of the description parameters can reduce the storage space of electrical signal data.
- step 106 determines the type of each electrical signal according to the start time point and the end time point of each electrical signal, including:
- Step 106A If the time difference between the end time point and the start time point of the target electrical signal is less than the preset time, it is determined that the type of the target electrical signal is a short signal.
- the short signal refers to a non-periodic electrical signal with a single duration of less than 50ms. Therefore, the preset time can be determined as 50ms.
- Step 106B if the time difference between the end time point and the start time point of the target electrical signal is greater than the preset time, it is determined that the type of the target electrical signal is a long signal.
- the long signal refers to an electrical signal composed of multiple periodic sine waves with a single duration greater than or equal to 50ms.
- the time difference between the end time point and the start time point of the target electrical signal is greater than or equal to 50 ms, it can be determined as a long signal.
- the electrical signal in the electrical signal combined data is divided into the long signal by comparing the duration of the electrical signal with the preset time With short signals, it is convenient to obtain the corresponding description parameters later.
- step 108 correspondingly obtains the description parameters of each segment of the electrical signal according to the type of each segment of the electrical signal, including:
- Step 108A if the type of the target electrical signal is a short signal, read the standard short signal set stored in the effect library.
- the effect library includes a pre-designed short signal set. Since the short signal duration is determined and short, the designed short signals can be packaged in advance to form a short signal set. The short signals in the electrical signal combination data designed later are all based on the short signals in the short signal set, so the standard short signal set stored in the read effect library can be used to match the target electrical signal.
- Step 108B matching the target electrical signal with the standard short signal in the standard short signal set, to obtain a target standard short signal matching the target electrical signal, and assigning the short signal name corresponding to the target standard short signal,
- the signal strength of the target electrical signal is used as a description parameter of the target electrical signal.
- the target electric signal and the standard short signal are judged based on the similarity of the electric signal duration, signal shape and other standards, so as to obtain the target standard short signal with the highest similarity.
- the short signal name is a name designed to distinguish standard short signals, so each short signal name corresponds to a unique standard short signal. Use the short signal name as the description parameter, and use the short signal name as an index to search for the corresponding standard short signal in the effect library when restoring the electrical signal later.
- the different signal strength of the electrical signal will cause the drive chip to obtain different vibration strengths when outputting to the motor.
- the signal strength of the target electrical signal is used as the description parameter to adjust the signal strength of the target standard short signal obtained when the electrical signal is subsequently restored. Obtain the signal strength required by the target electrical signal. Specifically, the adjustment of the signal strength is achieved by adjusting the voltage of the electrical signal.
- the short signal name of the target standard short signal and the signal strength of the target electrical signal are correspondingly used as the description parameters for the parameterized description of the short signal.
- the complete short signal data is not included in the description parameter, but is obtained from the effect when the subsequent signal is restored. Therefore, the short signal type electrical signal can be protected by the method of the embodiment of the invention.
- step 108 correspondingly obtains the description parameters of each segment of the electrical signal according to the type of each segment of the electrical signal, including:
- Step 108a If the type of the target electrical signal is a long signal, read the envelope signal of the target electrical signal and identify the key points of the envelope signal.
- the envelope signal is embodied in the image as the connection of the peak point of the long signal, and the key point is embodied as the inflection point of the connection.
- envelope signal 2 is a hexagon in the figure
- key point 3 of envelope signal 2 Is the 6 vertices in the graph. Since the long signal is composed of a periodic sine function with a constant frequency and a linear change in the peak value, the envelope signal obtained is symmetrical up and down, that is, there are key points containing repeated description parameters in the envelope signal, so in actual operation, it can only be relatively high The 4 key points are identified.
- Step 108b Use a recognition algorithm to identify the time point, signal strength, and frequency information corresponding to each key point in the envelope signal, and use the time point, the signal strength, and the frequency information as the description parameters of the target electrical signal .
- the envelope signal carries the description parameters of the long signal that need to be recorded, and the description parameters of the corresponding long signal are obtained by obtaining the time point, signal strength, and frequency information of the key points. Since the long signal is composed of multiple periodic sine waves, there is an inherent characteristic that the frequency of each periodic sine wave is constant, and the peak value linearly changes. In order to fully describe the long signal, it is necessary to obtain key points in time, signal strength, and frequency information. To indicate the corresponding long signal. Obtaining the signal intensity of the key point is used to reflect the vibration intensity amplitude of the corresponding periodic signal at a specific time point, and obtaining the frequency information of the key point is used to reflect the frequency of the corresponding periodic signal.
- the above parameterized description method of motor electric signal when the target electric signal is a long signal, read the envelope signal of the target electric signal and the key points in the envelope signal, and use the time point, signal strength, and frequency information of the key point as the description Parameters, used for parameterized description of long signals.
- the description parameters of the long signal cannot be directly output to the motor through the driving chip, it needs to be restored to the long signal through the signal generation algorithm before it can be used directly. Therefore, the electrical signals of the long signal type are protected by parameterized description.

- the embodiment of the present invention obtains the start time point and the end time point of each segment of the electrical signal by obtaining the duration of each signal segment and the mean value of the corresponding absolute value of the vibration amplitude, thereby combining the electrical signals in the data.

Description
本发明涉及马达电信号技术领域，尤其是涉及一种马达电信号参数化描述方法、装置、设备和介质。
马达是一种由电信号驱动，产生物理运动的电子器件，通常在电子设备中使用。马达通过产生振动，以触觉的形式反馈给用户，而不同的马达振动带给用户不同的触觉反馈。由于决定马达振动形式的是电信号，采用不同的电信号对马达进行驱动，输出的振动形式也将不同，因此常通过采用电信号组合数据的方式满足用户多变的需求。
对于电信号组合数据的储存而言，通常都是以直接驱动马达的电信号数据形式进行保存，这样一旦数据泄露，对方就可以直接使用，进而导致马达的振动形式被抄袭。这种传统的电信号组合数据形式不能实现数据的自我保护，保密性较低。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在一个实施例中，如图1所示，提供了一种马达电信号参数化描述方法，具体包括以下步骤：
步骤102，获取马达电信号数据，所述马达电信号数据为电信号组合数据。
其中，电信号组合数据是指马达可直接使用的电信号数据。马达在使用到不同的电信号组合数据时能通过驱动芯片输出相对应的振动形式。
步骤104，读取所述电信号组合数据中包含的每一段电信号，记录读取所述每一段电信号的起始时间点与终止时间点。
其中，电信号组合数据包括不同类型的电信号。记录读取每一段电信号的起始时间点与终止时间点用于判断对应每一段电信号的类型。
步骤106，根据所述每一段电信号的起始时间点与终止时间点确定所述每一段电信号的类型。
具体的，通过计算读取每一段电信号的起始时间与终止时间得到每一段电信号的时长，从而根据每一段电信号的时长相应的判断电信号的类型。
步骤108，根据所述每一段电信号的类型相应的获取所述每一段电信号的描述参数。
由于不同类型的电信号在周期性、频率等方面存在不同的特点，为使描述参数能准确、完整的描述电信号，需针对不同类型的电信号获取相应的描述参数。
步骤110，获取预设的参数描述模板，将所述每一段电信号的描述参数填入所述预设的参数描述模板中进行保存记录，得到与所述电信号组合数据对应的组合描述参数。
在一个实施例中，参数描述模板可以是HPDE（Haptic Pattern Description）描述模板，针对不同的类型的电信号需要填入相应的描述参数，比如，对于短信号而言将描述参数填入HPDE描述模板后得到：
"Event":{
"EventType":"PREBAKED",
"RelativeTime":100,
"SignalName":"A9",
"Strength":"MEDIUM"
}
对于长信号而言将描述参数填入HPDE描述模板后得到：
"Event":{
"EventType":"ENVELOPE",
"RelativeTime":500,
"Duration":600,
"Points":[[0,
0, 175], [100, 0.6, 175], [500, 0.6, 175], [600, 0, 175]]
}
其中Type标识电信号的类型，PREBAKED、ENVELOPE分别对应短信号和长信号，对每种类型的信号参数设置相应的值。通过将每一段电信号的描述参数都填入对应的参数描述模板中进行保存记录，得到与电信号组合数据对应的组合描述参数。
步骤112，根据所述组合描述参数生成振动信号用于驱动马达振动。
具体的，当需要使用到组合描述参数中的短信号时，可以以短信号名称作为索引，在效果库中索引得到对应的短信号。当需要使用到组合描述参数中的长信号时，可以获取长信号对应的描述参数结合信号生成算法近似还原得到长信号。
上述马达电信号参数化描述方法，通过读取电信号组合数据，并根据电信号组合数据中每一段电信号的起始时间点与终止时间点确定每一段电信号的类型。再根据每一段电信号的类型相应的获取每一段电信号的描述参数。最后通过将每一段电信号的描述参数填入预设的参数描述模板中，以得到与电信号组合数据对应的组合描述参数。本发明实施例采用描述参数的方式描述电信号组合数据，可以避免电信号数据的直接暴露，能对电信号起到一定保护作用。同时，对于长信号类型的电信号而言，对应的描述参数在使用时可以被实时还原成电信号，因此描述参数的储存方式可以减少电信号数据的储存空间。
在一个实施例中，如图2所示，步骤106根据所述每一段电信号的起始时间点与终止时间点确定所述每一段电信号的类型，包括：
步骤106A，若目标电信号的终止时间点与起始时间点的时间之差小于预设时间时，确定所述目标电信号的类型为短信号。
其中，短信号是指单次时长小于50ms的非周期电信号。因此预设时间可以确定为50ms。
步骤106B，若目标电信号的终止时间点与起始时间点的时间之差大于预设时间时，确定所述目标电信号的类型为长信号。
其中，长信号是指单次时长大于等于50ms，由多个周期正弦波组成的电信号。相应的，当目标电信号的终止时间点与起始时间点的时间之差大于等于50ms，可以确定为长信号。
上述马达电信号参数化描述方法，鉴于长信号与短信号在单次时长上体现的差异，通过将电信号的时长与预设时间进行比较，从而将电信号组合数据中电信号区分为长信号与短信号，便于后续获取相应的描述参数。
在一个实施例中，如图3所示，步骤108根据所述每一段电信号的类型相应的获取所述每一段电信号的描述参数，包括：
步骤108A，若所述目标电信号的类型为短信号，读取效果库中保存的标准短信号集。
其中，效果库包括预先设计好的短信号集。由于短信号时长确定且较短，可提前将已设计好的短信号打包，形成短信号集的形式。而后续设计的电信号组合数据中的短信号都是以短信号集中的短信号为基础，因此读取效果库中保存的标准短信号集可用于与目标电信号进行匹配。
步骤108B，将所述目标电信号与所述标准短信号集中的标准短信号进行匹配，得到与所述目标电信号匹配的目标标准短信号，将所述目标标准短信号对应的短信号名称、所述目标电信号的信号强度作为所述目标电信号的描述参数。
其中，目标电信号与标准短信号通过电信号时长、信号形状等标准做相似度判断，从而得到相似度最高的目标标准短信号。短信号名称是为起到区分标准短信号的作用而设计的名称，因此每个短信号名称对应唯一的标准短信号。将短信号名称作为描述参数，用于后续还原电信号时以短信号名称作为索引搜索效果库中相应的标准短信号。电信号不同的信号强度会导致驱动芯片输出给马达时获得不同的振动强度，将目标电信号的信号强度作为描述参数，用于后续还原电信号时调整得到的目标标准短信号的信号强度，从而得到目标电信号需要的信号强度。具体的，信号强度的调整通过调整电信号的电压实现。
上述马达电信号参数化描述方法，当目标电信号为短信号时，相应的将目标标准短信号的短信号名称以及目标电信号的信号强度作为描述参数，用于对短信号的参数化描述，本发明实施例中，描述参数中不包括完整的短信号数据，而是在后续信号还原时才从效果中匹配获取，因此得以通过发明实施例的方法对短信号类型的电信号加以保护。
在一个实施例中，如图4所示，步骤108根据所述每一段电信号的类型相应的获取所述每一段电信号的描述参数，包括：
步骤108a，若所述目标电信号的类型为长信号，读取所述目标电信号的包络信号并识别所述包络信号的关键点。
其中，包络信号在图像中体现为长信号峰值点的连线，关键点体现为连线的拐点。在一个实施例中，如图5所示，当包络信号2与长信号1都以图像的形式表示时，包络信号2为图中的六边形，而包络信号2的关键点3为图中的6个顶点。由于长信号由频率不变，峰值线性变化的周期正弦函数组成，得到的包络信号上下对称，即包络信号中存在包含重复描述参数的关键点，因此在实际操作中可以只对相对靠上的4个关键点进行识别。
步骤108b，使用识别算法识别包络信号中每个关键点对应的时间点、信号强度、频率信息，将所述时间点、所述信号强度、所述频率信息作为所述目标电信号的描述参数。
包络信号内携带了长信号需要记录的描述参数，具体通过获取关键点的时间点、信号强度、频率信息得到对应长信号的描述参数。由于长信号是由多个周期正弦波组成，存在每个周期正弦波内频率不变，峰值线性变化的固有特点，为完整描述长信号，还需获取关键点的时间点、信号强度、频率信息来表示对应的长信号。获取关键点的信号强度用于反应对应周期信号在具体时间点上的振动强度幅值，获取关键点的频率信息用于反应对应周期信号的频率。
上述马达电信号参数化描述方法，当目标电信号为长信号时，读取目标电信号的包络信号以及包络信号内的关键点，将关键点的时间点、信号强度、频率信息作为描述参数，用于对长信号的参数化描述。本发明实施例中，由于长信号的描述参数不能直接通过驱动芯片输出给马达，还需结合信号生成算法进行还原为长信号后才能直接使用。因此通过参数化描述使长信号类型的电信号受到保护。
在一个实施例中，如图6所示，步骤104电信号是由多个信号片段组成的，所述读取所述电信号组合数据中包含的每一段电信号，记录读取所述每一段电信号的起始时间点与终止时间点，包括：
步骤104A，在所述电信号组合数据中，按照时间顺序依次获取每个信号片段的持续时间，且计算每个信号片段对应的振动幅值的绝对值的均值。
其中，时间顺序为电信号组合数据的设计顺序。每段电信号内包括多个电信号片段，依次得到每个信号片段的持续时间与对应的振动幅值的绝对值的均值用于对不同电信号进行划分。
步骤104B，根据每个信号片段的持续时间和对应的振动幅值的绝对值的均值确定每一段电信号的起始时间点与终止时间点。
具体的，电信号的起始时间点与终止时间点之间为一个完整的电信号。
本发明实施例通过得到每个信号片段的持续时间以及对应的振动幅值的绝对值的均值，来得到每一段电信号的起始时间点与终止时间点，从而将电信号组合数据中的电信号一个个完整的划分出来。
在一个实施例中，步骤104B根据每个信号片段的持续时间和对应的振动幅值的绝对值的均值确定每一段电信号的起始时间点与终止时间点，包括：
将首次查找到的持续时间大于第一预设时间且对应的振动幅值的绝对值的均值大于第一预设值的信号片段作为第一段电信号的起始片段。
其中，第一预设时间可以是5ms。第一预设值可以是0.1。按照电信号组合数据的设计顺序依次对间隔的电信号片段进行判断，当出现信号片段的段持续时间大于第一预设时间且对应的振动幅值的绝对值的均值大于第一预设值时，将该信号片段作为第一段电信号的起始片段。起始片段内包含第一段电信号的起始时间点。
在第一段电信号的起始片段后，将首次查找到的持续时间大于第二预设时间且对应的振动幅值的绝对值的均值小于第二预设值的信号片段作为所述第一段电信号的终止片段。
其中，第二预设时间可以是5ms。第二预设值可以是0.01。当查找到起始片段后，继续对后续的信号片段进行判断，直到出现信号片段的段持续时间大于第二预设时间且对应的振动幅值的绝对值的均值小于第二预设值时，将该信号片段作为第一段电信号的终止片段。在第一段电信号的起始片段与终止片段之间的信号片段都是归属于第一段电信号的信号片段。终止片段内包含第一段电信号的终止时间点。
在所述第一段电信号的终止片段后，将首次查找到的持续时间大于第一预设时间且对应的振动幅值的绝对值的均值大于第一预设值的信号片段作为第二段电信号的起始片段。
当第一电信号依据对应的起始片段与终止片段划分后，依照电信号组合数据的设计顺序继续对起始片段进行查找，查找的方式与第一段电信号的起始片段相同。将查找到的第一个起始片段作为第二段电信号对应的起始片段。
在所述第二段电信号的起始片段后，将首次查找到的持续时间大于第二预设时间且对应的振动幅值的绝对值的均值小于第二预设值的信号片段作为所述第二段电信号的终止片段，依次类推，直到遍历完所有信号片段。
相应的，第二段电信号的起始片段与终止片段之间的信号片段都是归属于第二段电信号的信号片段。依次类推，直到查找到所有电信号对应的起始片段与终止片段。
将每一段电信号的起始片段的起始点作为相应电信号的起始时间点，将所述每一段电信号的终止片段的终止点作为相应电信号的终止时间点。
上述马达电信号参数化描述方法，通过依次查找电信号中的起始片段与终止片段，得到每一段电信号的起始片段与终止片段，进而得到每一段电信号的起始时间点与终止时间点，用于后续为判断电信号的类型提供依据。
