Description

无线充电调整方法、装置、被充电设备及计算机存储介质Wireless charging adjustment method, device, charged device and computer storage medium 技术领域Technical field
本发明涉及无线充电技术,尤其涉及一种无线充电调整方法、装置、被充电设备及计算机存储介质。The present invention relates to wireless charging technologies, and in particular, to a wireless charging adjustment method, apparatus, charged device, and computer storage medium.
背景技术Background technique
在无线充电技术中,被充电设备通过接收无线充电设备发射的能量来实现无线充电。目前,无线充电设备的种类繁多,被充电设备的充电效率和充电功率均会随着无线充电设备的变化而发生改变,如此,使无线充电变得不稳定,甚至出现无线充电中断的情况。In the wireless charging technology, the charged device realizes wireless charging by receiving energy emitted by the wireless charging device. At present, there are many types of wireless charging devices, and the charging efficiency and charging power of the charged device change with the change of the wireless charging device. Thus, the wireless charging becomes unstable, and even the wireless charging is interrupted.
下面以电磁感应式无线充电技术为例进行说明,无线充电设备的线圈为初级线圈,被充电设备的线圈为次级线圈,被充电设备通过LC振荡电路来转移无线充电设备发射的能量。对于被充电设备的LC振荡电路,谐振电容的选取决定着无线充电的效率、稳定性和耦合性,谐振电容的选取还在很大程度上决定着被充电设备是否满足异物检测(Foreign Object Detection,FOD)标准。The electromagnetic induction wireless charging technology is taken as an example. The coil of the wireless charging device is a primary coil, and the coil of the charged device is a secondary coil. The charged device transmits the energy emitted by the wireless charging device through the LC oscillating circuit. For the LC oscillator circuit of the device being charged, the selection of the resonant capacitor determines the efficiency, stability and coupling of the wireless charging. The selection of the resonant capacitor largely determines whether the charged device satisfies the foreign object detection (Foreign Object Detection, FOD) standard.
被充电设备与无线充电设备的相对位置对无线充电的耦合性起着至关重要的作用,这里,将充电信号强度最大值对应的被充电设备在无线充电设备上的位置称为被充电设备的中心位置,如果被充电设备在无线充电设备上的位置对应的信号强度不是信号强度最大值,则将被充电设备在无线充电设备上的位置称为被充电设备的其他位置。显然,被充电设备处于中心位置时,无线充电的效率最高,而被充电设备处于其他位置时,无线充电的效率低于被充电设备处于中心位置时无线充电的效率。The relative position of the charged device and the wireless charging device plays a vital role in the coupling of the wireless charging. Here, the position of the charged device corresponding to the maximum value of the charging signal on the wireless charging device is referred to as the charged device. The central location, if the signal strength corresponding to the location of the charged device on the wireless charging device is not the signal strength maximum, the location of the device to be charged on the wireless charging device is referred to as the other location of the device being charged. Obviously, when the charged device is in the center position, the wireless charging efficiency is the highest, and when the charged device is in other positions, the wireless charging efficiency is lower than the wireless charging efficiency when the charged device is in the center position.
目前,不同的无线充电设备使用的初级线圈的形状/结构不同,有的无 线充电设备的线圈中心位置有磁铁,有的无线充电设备的线圈中心位置没有磁铁;有的无线充电设备包括多个线圈,而有的无线充电设备只有一个线圈。这样,被充电设备的次级线圈与无线充电设备的初级线圈的耦合性会随着初级线圈的变化而产生变化;如果不同的无线充电设备的发射功率相同,则被充电设备的LC振荡电路的振荡频率也会发生改变,使无线充电变得不稳定,例如,有时出现无线充电中断的情况,有时会导致无线充电设备的初级线圈出现磁饱和的情况。At present, the shape/structure of the primary coil used by different wireless charging devices is different, and some are not The center of the coil of the line charging device has a magnet, and some of the wireless charging devices have no magnet at the center of the coil; some wireless charging devices include multiple coils, and some wireless charging devices have only one coil. In this way, the coupling between the secondary coil of the charged device and the primary coil of the wireless charging device changes with the change of the primary coil; if the transmission power of different wireless charging devices is the same, the LC oscillation circuit of the charged device The oscillation frequency also changes, making the wireless charging unstable. For example, there is a case where the wireless charging is interrupted, and sometimes the magnetic saturation of the primary coil of the wireless charging device occurs.

这里,所述被充电设备充电电路的参数可以是被充电设备充电电路中任意一个器件的一个参数或多个参数,例如,所述被充电设备充电电路的参数为被充电设备充电电路中一个电容的电容值。 Here, the parameter of the charged device charging circuit may be one parameter or a plurality of parameters of any one of the devices in the charging device charging circuit. For example, the parameter of the charged device charging circuit is a capacitor in the charging circuit of the charging device. The value of the capacitor.
这里,在多次调整被充电设备充电电路的参数时,被充电设备充电电路的参数的取值范围可以预先设定。需要说明的是,可以预先设定调整被充电设备充电电路的参数的次数,也可以在调整被充电设备充电电路的参数的时间达到设定在时间长度时,结束多次调整被充电设备充电电路的参数的过程。Here, when the parameters of the charging circuit of the charging device are adjusted a plurality of times, the value range of the parameters of the charging circuit of the charging device can be set in advance.

在本实施例中,将LC振荡电路的第一谐振电容Cs作为待调整器件。In the present embodiment, the first resonance capacitance Cs of the LC oscillation circuit is taken as the device to be adjusted.
步骤201:多次调整被充电设备LC振荡电路的参数;在每次调整被充电设备LC振荡电路的参数时,将所述待调整器件与同种类的器件进行并联。Step 201: Adjust the parameters of the LC oscillation circuit of the device to be charged a plurality of times; and adjust the parameters of the LC circuit of the device to be charged in parallel with the devices of the same type each time.
图4为本发明无线充电调整方法的第二实施例中LC振荡电路的第二结 构示意图。如图4所示,在上述LC振荡电路中设置有N个待并联的电容,N为大于1的自然数,这N个待并联的电容分别表示为第1待并联电容Cs1至第N待并联电容CsN,这N个待并联的电容中任意两个电容的电容值不同。每个待并联的电容通过一个电子开关接入所述被充电设备充电电路,第i待并联电容Csi通过第i电子开关Ki接入被充电设备充电电路,i取1至N。4 is a second junction of an LC oscillating circuit in a second embodiment of the wireless charging adjustment method of the present invention Schematic diagram. As shown in FIG. 4, in the LC oscillation circuit, N capacitors to be connected in parallel are arranged, and N is a natural number greater than 1, and the N capacitors to be connected in parallel are respectively represented as a first to-parallel capacitor Cs1 to an N-th parallel capacitor. CsN, the capacitance values of any two of the N capacitors to be connected in parallel are different. Each capacitor to be connected in parallel is connected to the charged device charging circuit through an electronic switch, and the i-th parallel capacitor Csi is connected to the charged device charging circuit through the ith electronic switch Ki, and i takes 1 to N.
这里,每个电子开关的通断状态均是由控制信号控制的,在初始时,在控制信号的控制下,上述每个电子开关处于断开状态,显然,第1待并联电容Cs1至第N待并联电容CsN均未接入被充电设备充电电路。Here, the on-off state of each electronic switch is controlled by a control signal. At the initial time, under the control of the control signal, each of the above-mentioned electronic switches is in an off state, obviously, the first to-be-parallel capacitors Cs1 to N None of the parallel capacitors CsN are connected to the charging circuit of the charged device.
当被充电设备正在进行无线充电时,对LC振荡电路的参数进行N次调整,在每次调整LC振荡电路的参数时,控制上述的一个电子开关闭合,并控制其余的电子开关断开,任意两次调整LC振荡电路的参数时闭合的电子开关不同。这样,在每次调整LC振荡电路的参数时,就会改变LC振荡电路的串联谐振电容的电容值;例如,当第i电子开关Ki闭合时,第i待并联电容Csi接入LC振荡电路,此时LC振荡电路的串联谐振电容的电容值为第i待并联电容Csi的电容值与第一谐振电容Cs的电容值的和。When the charged device is performing wireless charging, the parameters of the LC oscillating circuit are adjusted N times, and each time the parameters of the LC oscillating circuit are adjusted, one of the above electronic switches is controlled to be closed, and the remaining electronic switches are controlled to be disconnected. The closed electronic switch is different when the parameters of the LC oscillation circuit are adjusted twice. Thus, each time the parameters of the LC oscillating circuit are adjusted, the capacitance value of the series resonant capacitor of the LC oscillating circuit is changed; for example, when the ith electronic switch Ki is closed, the ith to-be-parallel capacitor Csi is connected to the LC oscillating circuit. At this time, the capacitance value of the series resonance capacitor of the LC oscillation circuit is the sum of the capacitance value of the ith to-series capacitor Csi and the capacitance value of the first resonance capacitor Cs.
本实施例中,控制信号可以由被充电设备生成,每个电子开关的通断状态均由控制信号进行自动控制,提高调整被充电设备充电电路的参数的效率。In this embodiment, the control signal can be generated by the charged device, and the on/off state of each electronic switch is automatically controlled by the control signal to improve the efficiency of adjusting the parameters of the charging circuit of the charging device.
步骤202:将获取的各个充电信号强度的最大值对应的被充电设备LC振荡电路的参数确定为被充电设备LC振荡电路的参数。Step 202: Determine parameters of the charged device LC oscillation circuit corresponding to the obtained maximum values of the respective charging signal strengths as parameters of the charged device LC oscillation circuit.
这里,在每次调整LC振荡电路的参数后,由于LC振荡电路的参数的改变,使无线充电设备的初级线圈和被充电设备的电感之间的耦合性发生改变,此时,被充电设备的充电信号强度也会发生变化。因此,在将获取的各个充电信号强度的最大值对应的被充电设备LC振荡电路的参数确定 为被充电设备LC振荡电路的参数后,可以提高无线充电设备的初级线圈和被充电设备的电感之间的耦合性,并提高无线充电效率。Here, after each adjustment of the parameters of the LC oscillating circuit, the coupling between the primary coil of the wireless charging device and the inductance of the device to be charged is changed due to a change in the parameters of the LC oscillating circuit, at this time, the charged device The charging signal strength will also change. Therefore, the parameters of the LC circuit of the charged device corresponding to the maximum value of the acquired respective charging signal strengths are determined. After the parameters of the circuit of the charged device LC oscillate, the coupling between the primary coil of the wireless charging device and the inductance of the device to be charged can be improved, and the wireless charging efficiency is improved.

FIG. 5 is a flowchart of a third embodiment of a wireless charging adjustment method according to the present invention. As shown in FIG. 5, the method includes:
步骤500与步骤200完全一致,这里不再重复描述。Step 500 is completely consistent with step 200, and the description is not repeated here.
步骤501与步骤201基本一致,区别点在于,在每次调整被充电设备LC振荡电路的参数时,将与所述待调整器件同种类的器件代替所述待调整器件接入所述被充电设备充电电路。Step 501 is substantially the same as step 201. The difference is that each time the parameter of the LC circuit of the device to be charged is adjusted, the device of the same kind as the device to be adjusted is replaced with the device to be adjusted to access the device to be charged. Charging circuit.
具体地,在本发明无线充电调整方法的第二实施例的基础上,设置第N+1电子开关,第N+1电子开关与第一谐振电容Cs串联连接;第N+1电子开关与第一谐振电容Cs串联后形成的支路与第i待并联电容Csi和第i电子开关Ki串联后形成的支路并联。在初始时,在控制信号的控制下,第N+1电子开关处于闭合状态,第一谐振电容Cs被接入LC振荡电路,这时LC振荡电路可以正常工作。Specifically, on the basis of the second embodiment of the wireless charging adjustment method of the present invention, an N+1th electronic switch is provided, and the (N+1)th electronic switch is connected in series with the first resonant capacitor Cs; the (N+1)th electronic switch and the first A branch formed by connecting a resonant capacitor Cs in series is connected in parallel with a branch formed by connecting the ith to-series capacitor Csi and the ith electronic switch Ki in series. Initially, under the control of the control signal, the N+1th electronic switch is in a closed state, and the first resonant capacitor Cs is connected to the LC oscillating circuit, at which time the LC oscillating circuit can operate normally.
当被充电设备正在进行无线充电时,对LC振荡电路的参数进行N次调整,在每次调整LC振荡电路的参数时,控制第N+1电子开关断开,控制第1电子开关K1至第N电子开关KN中的一个电子开关闭合,控制第1电子开关K1至第N电子开关KN中的其余电子开关断开,任意两次调整LC振荡电路的参数时闭合的电子开关不同。这样,在每次调整LC振荡电路的参数时,就会改变LC振荡电路的串联谐振电容的电容值;例如,当第i电子开关Ki闭合时,第i待并联电容Csi接入LC振荡电路,此时LC振荡电路的串联谐振电容为第i待并联电容Csi。When the charged device is performing wireless charging, the parameters of the LC oscillation circuit are adjusted N times, and each time the parameters of the LC oscillation circuit are adjusted, the N+1th electronic switch is controlled to be turned off, and the first electronic switch K1 is controlled. An electronic switch in the N electronic switch KN is closed, and the remaining electronic switches in the first electronic switch K1 to the Nth electronic switch KN are controlled to be turned off, and the closed electronic switches are different when the parameters of the LC oscillation circuit are adjusted twice. Thus, each time the parameters of the LC oscillating circuit are adjusted, the capacitance value of the series resonant capacitor of the LC oscillating circuit is changed; for example, when the ith electronic switch Ki is closed, the ith to-be-parallel capacitor Csi is connected to the LC oscillating circuit. At this time, the series resonant capacitor of the LC oscillating circuit is the ith to-be-parallel capacitor Csi.
步骤502与步骤202完全一致,这里不再赘述。 Step 502 is completely consistent with step 202, and details are not described herein again.

FIG. 6 is a flowchart of a fourth embodiment of a wireless charging adjustment method according to the present invention. As shown in FIG. 6, the method includes:
步骤600与步骤200基本一致,区别点在于,在被充电设备充电电路的各个器件中选取待调整器件时,将一个可调节参数的器件作为待调整器件。例如,如果被充电设备充电电路的一个电容为可调电容,则可以将该可调电容作为待调整器件。Step 600 is basically the same as step 200. The difference is that when the device to be adjusted is selected from the devices of the charging circuit of the charging device, a device with adjustable parameters is used as the device to be adjusted. For example, if a capacitor of the charging circuit of the charging device is a tunable capacitor, the tunable capacitor can be used as the device to be adjusted.
在一实施例中,在被充电设备充电电路的各个器件中选取待调整器件时,可以将电控可调参数的器件作为待调整器件,这里,电控可调参数的器件在接收到控制信号时,可以基于对应的控制信号调节自身的参数。In an embodiment, when the device to be adjusted is selected in each device of the charging circuit of the charging device, the device with the electronically adjustable parameter can be used as the device to be adjusted, where the device with the electronically adjustable parameter receives the control signal. At that time, its own parameters can be adjusted based on the corresponding control signals.
步骤601与步骤201基本一致,区别点在于,在每次调整被充电设备LC振荡电路的参数时,对待调整器件的可调节参数进行调节,任意两次调节后待调整器件的参数均不相同,每次参数调节后待调整器件的参数不同于初始时待调整器件的参数。例如,当待调整器件为可调电容时,各次参数调节后该可调电容的电容值均不相同,且每次参数调节后该可调电容的电容值不同于初始时该可调电容的电容值。Step 601 is basically the same as step 201. The difference is that each time the parameter of the LC circuit of the charging device is adjusted, the adjustable parameter of the device to be adjusted is adjusted, and the parameters of the device to be adjusted are different after any two adjustments. The parameters of the device to be adjusted after each parameter adjustment are different from the parameters of the device to be adjusted at the initial time.

Capacitance value.
在一实施例中,如果待调整器件为电控可调参数的器件,那么在本步骤中,在对待调整器件进行参数调节时,利用待调整器件的控制信号进行控制。In an embodiment, if the device to be adjusted is a device with electronically adjustable parameters, then in this step, when the parameter to be adjusted is to be adjusted, the control signal of the device to be adjusted is used for control.
步骤602与步骤202完全一致,这里不再赘述。Step 602 is completely consistent with step 202, and details are not described herein again.
第五实施例Fifth embodiment
为了能更加体现本发明的目的,在本发明第一实施例的基础上,进行进一步的举例说明。图7为本发明无线充电调整方法的第五实施例的流程图,如图7所示,该方法包括: In order to further embodies the object of the present invention, further exemplification will be made on the basis of the first embodiment of the present invention. FIG. 7 is a flowchart of a fifth embodiment of a wireless charging adjustment method according to the present invention. As shown in FIG. 7, the method includes:
步骤700:当被充电设备正在进行无线充电时,判断当前时刻当前充电位置的充电信号强度是否大于充电信号强度阈值,如果大于,则不调整被充电设备充电电路的参数,继续基于当前被充电设备充电电路的参数进行无线充电;如果当前时刻当前充电位置的充电信号强度不大于充电信号强度阈值,则跳至步骤701。Step 700: When the charged device is performing wireless charging, determine whether the charging signal strength of the current charging position at the current time is greater than the charging signal strength threshold. If it is greater, the parameter of the charging circuit of the charging device is not adjusted, and the current charging device is continued. The parameters of the charging circuit are wirelessly charged; if the charging signal strength of the current charging position at the current time is not greater than the charging signal strength threshold, then the process goes to step 701.
本步骤中,充电信号强度阈值可以进行实现设置,例如,充电信号强度阈值为0.5A,如果当前时刻当前充电位置的充电信号强度为0.6A,则当前时刻当前充电位置的充电信号强度大于充电信号强度阈值。这里,如果当前时刻当前充电位置的充电信号强度大于充电信号强度阈值,则说明当前无线充电设备初级线圈和被充电设备次级线圈的耦合性较好,因此,不需要调整被充电设备充电电路的参数。In this step, the charging signal strength threshold can be set. For example, the charging signal strength threshold is 0.5A. If the charging signal strength of the current charging position is 0.6A at the current moment, the charging signal strength of the current charging position is greater than the charging signal at the current moment. Intensity threshold. Here, if the charging signal strength of the current charging position at the current moment is greater than the charging signal strength threshold, it indicates that the coupling between the primary coil of the wireless charging device and the secondary coil of the charged device is better, and therefore, it is not necessary to adjust the charging circuit of the charged device. parameter.
步骤701与步骤200基本一致,区别点在于,去掉了判断被充电设备是否正在进行无线充电的过程,直接在被充电设备充电电路的各个器件中选取待调整器件。Step 701 is basically the same as step 200. The difference is that the process of determining whether the charged device is performing wireless charging is removed, and the device to be adjusted is directly selected from the devices of the charging circuit of the charged device.
步骤702~703与步骤201~202完全一致,这里不再赘述。Steps 702-703 are completely consistent with steps 201-202, and are not described herein again.
