其中,所述发光显示单元111用于显示吸尘器的灰尘浓度信息;所述驱动单元112用于接收来自控制器610的与设定的测量参数测量值相对应的第一显示指令,对发光显示单元111提供驱动信号,使发光显示单元111根据第一显示指令的具体数值呈现不同的发光状态,从而对灰尘浓度信息进行显示。

检测灰尘量时,接收器211-2接收发射器211-1发出的光信号,并输出与受光量相对应的检测信号。接收器211-2的检测信号通过传感器电路213后变成脉冲或方波,由所述检测信号输入端输入到主控板中。根据主控板检测到的脉冲或方波的数量,就可获知灰尘的数量多少,即脉冲的数量越多,灰尘的数量也越多,脉冲的数量越少,灰尘的数量越少。另外,灰尘的颗粒尺寸越大,脉冲的宽度越宽,灰尘的颗粒尺寸越小,脉冲的宽度越小。
主控板内预置有电信号预设值,该电信号预设值为基准电压值,也可以采用电流、光强、脉冲表示,该基准电压值的设定与传感器211的灵敏度相关,具体的确定方式为在校准环境下,通过检测接收器211-2的检测信号获得。所述校准环境为吸尘器未工作且所处环境为较为干净的正常环境。
下面对灰尘检测装置灵敏度的调整情况进行描述。
请参照图8所示,正常情况下,在吸尘过程中,当灰尘通道内有灰尘流过时,发射器211-1发出的一部分光被灰尘遮挡,接收器211-2的受光量会减少。接收器211-2的检测信号通过基准信号输入端输入到主控板中,主控板接收到正常的电信号值。
在灰尘检测的过程中,若发射器211-1表面附着有灰尘,则发射器211-1发出的光在达到灰尘通道内的灰尘表面前,有部分光被附着在发射器211-1表面的灰尘遮挡,导致接收器211-2的受光量相比正常情况减少。
调整传感器灵敏度的方式是通过在主控板内设置预设值,主控板将所述基准信号输入端接收到的电信号值与所述主控板内的预设值进行比较,并根据二者的比较结果,调整对所述发射器211-1控制端的供电,以调节所述发射器211-1的发光强度,直到所述基准信号输入端所获得的电信号值与所述预设值之间的差值在预先确定的阈值范围之内。具体的调整方法有多种,本实施例提供了一种具体的实现方案,详见后续部分。
所述阈值范围根据吸尘器工作环境下对应不同情况的灰尘颗粒的大小、灰尘量的多少进行合理的设置,调整发射器211-1发光强度具体是通过调整发射器211-1的驱动电压的方式来实现增加或减少发光强度。
可选的,预设值的设置在吸尘操作前可以根据环境的需求进行调整。另外,预设值也可以在吸尘操作的过程中进行实时的校准,下面对此进行说明:
主控板根据检测信号输入端获得的检测信号,并根据所述灰尘颗粒值或所述灰尘浓度值校准所述预设值,以使所述预设值与所述模拟信号值接近或相同。
可选的,所述主控板以下述方式获得灰尘浓度值:以所述检测信号中, 单位时间内的方波的数量推算所述灰尘浓度值。
可选的,所述主控板通过统计所述检测信号中所出现的方波的宽度,以此推算所述灰尘颗粒尺寸。
可选的,请参照图6所示,灰尘检测装置210还包括:电机模块214,所述电机模块214与所述控制器610的电机控制输出口连接,根据电机控制输出口提供的给定值调整吸尘电机功率或者电机转速;所述主控板根据所述检测信号推算出灰尘状况后,将所获得的灰尘状况代入其内部设置的给定值计算方法中,获得所述吸尘电机控制输出口提供的给定值。
以上灰尘检测装置中包括透明视窗212,所述透明视窗212为所述传感器211的发射器211-1和接收器211-2之间提供了通过路径,实现了在转接管位置对灰尘浓度的测量;但是由于所述吸尘器工作在灰尘很多的环境,在吸尘器使用过程中,所述透明视窗212很快就沾染灰尘,透明度快速下降,从而使所述灰尘检测装置不能实现对灰尘状况的准确测量。为了解决上述问题,在本实施中,还在透明视窗212上安置了专用的刮条,用于清洁所述透明视窗212.
请参照图9,其为本申请灰尘检测装置的刮条机构的示意图。
所述刮条机构包括:刮条215及刮条挡板216,所述刮条挡板216固定在所述透明视窗212的两端,所述刮条215设置在所述刮条挡板216之间,并可以在所述刮条挡板216之间以贴合所述透明视窗212表面的方式运动;其所贴合的表面是透明视窗212容易被污染的一面,或者,在透明视窗212的两面都设置刮条215。
相应的,为了驱动所述刮条215,所述刮条机构还包括刮条电机(图未示出),以及刮条电机控制单元(图未示出);所述刮条电机的旋转通过机械机构带动所述刮条的运动;所述刮条电机控制单元用于控制所述刮条电机的旋转。
所述刮条电机的旋转包括正转和反转,所述正转和反转经过所述机械机构可以转换为所述刮条215在向左、右两个方向的运动。所述刮条电机及其 所述机械结构可以采用多种方式实现;例如,所述刮条电机可以采用常用的小型直流电机,所述机械机构则可以采用小型丝杠;所述刮条215的一端设置套接配合所述丝杠的内螺纹孔,随着丝杠被所述刮条电机带动旋转,而沿着丝杠轴线移动,从而实现刮条215贴合所述透明视窗212表面的运动;在刮条电机改变旋转方向时,所述刮条215就可以向相反方向移动。当然,实现刮条电机带动刮条215移动的可能技术方案有很多,在此不予详细介绍。
可选的,所述刮条电机控制单元包括为所述刮条电机供电的电路,以及所述主控板上控制所述电路的控制程序;所述刮条电机需要根据情况不断在正转和反转之间切换,因此,为其供电的电路可以采用易于改变直流电机的供电方向的H桥电路,具体如图10所示。所述控制器610通过控制所述H桥电路的导通以及导通方向,控制刮条电机的启停,以及正转和反转。
请参照图10,其为本申请透明视窗刮条机构的控制电路原理图;下面对擦拭透明视窗的电路原理进行说明。
所述刮条机构的控制电路主体为H桥电路;该电路由Q1、Q2、Q3、Q4四个可控硅或者大功率三极管组成。
当Q1和Q4被控打开,同时Q2和Q3被控关闭时,刮条电机正转,当Q1和Q4被控关闭,同时Q2和Q3被控打开时,刮条电机反转。所述Q1-Q4的控制通过主控板的控制端的输出端口输出的控制电压实现,而所述输出端口如何输出控制电压,则通过内部的控制程序实现。
在透明视窗212的两侧分别安装一个挂条挡板216用来限位,当电机控制的刮条电机正转时,刮条215向一个方向移动,例如,从左向右移动,由于刮条215的底面贴合在所述透明视窗212上,刮条215开始清理透明视窗212表面的脏物,当刮条215碰到挂条挡板216时,则刮条215被挡住,刮条电机的旋转受阻,导致通过电阻R1的电流显著增加,此时,当主控板检测到通过电阻R1的电流增大时,就会根据内部控制程序的设定,切换刮条电机的转向,使所述刮条215向相反方向移动;同样的,当刮条215碰到另外一边的挂条挡板216时,会再次进行换向,如此往复,便可实现对透明视窗212 进行清理。
从以上工作原理可以看出,为了实现对刮条215往复运动的控制,需要设置电流检测模块,用于检测流过所述刮条电机的电流;在刮条电机电流大于规定阈值时,所述电流检测模块输出的检测值使所述主控板控制所述刮条电机旋转方向的切换。
在图10所示出电路中,所述电阻R1以及检测流过电阻R1的电流的机构,组成所述电流检测模块。该电路实现电流检测的具体原理如下:将电阻R1的正极的电压值引入所述主控板的某一个输入端口,主控板根据该输入端口接入的电压值即可推算流过所述电阻R1的电流值,若所述电阻R1正极的电压值高于主控板内部设置的一个门限值,则可以判定流过所述电阻R1的电流过高了,说明所述刮条215的运动被所述刮条挡板216挡住,所述主控板通过改变其连接所述Q1-Q4的控制端的输出端口的输出值,改变所述H桥电路的导通状态,从而改变所述刮条电机的旋转方向,实现刮条215的往复运动。
启动所述刮条机构的时机可以根据对所述传感器的控制和信号接收的情况来判断;例如,当主控板以最大的发射强度所需要的电流或者电压为所述发射器211-1供电时,接收器211-2仍然无法收到稳定的信号,则需要启动所述刮条机构运转,对所述透明视窗212进行清洁。在进行一段时间的清洁后——具体的清洁时间可以预设一个时间参数——若接收器211-2可以顺畅的获得稳定的信号时,则说明红外信号可以正常传送,则刮条机构停止运转。
设置上述灰尘检测装置,具有以下有益效果:
(1)将灰尘检测装置设置在连通吸尘器尘桶和风道管的转接管外的方式,从灰尘吸入吸尘器的入口附近的位置进行灰尘信号的检测,实现了精确的采集当前灰尘浓度、识别大颗粒灰尘的效果,并且通过透明视窗的保护,减轻了灰尘检测装置发射端和接收端的灰尘积压,避免了灰尘传感器使用过程中灵敏度下降,提高了灰尘浓度检测的精度。
(2)将传感器设置在尘桶或风道管的管壁部分,实现了灰尘传感器不会阻碍风道的进风的技术效果,并且结合透明视窗的设置,实现了对灰尘浓度 进行检测的技术效果。
(3)通过设置挂条和挂条挡板,从而可以对透明视窗进行清洁,使传感器发射器和接收器之间的光线路径能够不被遮挡,提高接收灰尘检测信号的灵敏度。
下面介绍本申请的气压检测保护系统300。

为了更好的理解上述方案,下面将结合说明书附图以及具体的实施方式对对上述技术方案进行说明。
请参考图11,其为本申请实施例的吸尘器气压检测保护系统逻辑框图。
本申请实施例的一种吸尘器气压检测保护系统300,包括气压检测模块310、第一转换器621、比较器320、第一控制器611。
所述气压检测模块310,设置在吸尘器气压敏感位置。吸尘器气压敏感位置包括主吸口位置、尘桶位置、出风口位置、马达内腔位置,气压检测模块310可以设置在上述位置中的一种,也可以全部都设置。所述气压检测模块310通过连通到所述吸尘器气压敏感位置的采样气管获得气压采样,气压检测模块310在吸尘器运行期间实时检测所述吸尘器气压敏感位置的气压值,并转换为电信号。所述气压检测模块310具体可以采用多种方式实现,现有技术下已经有多种用于测量气压的压力传感器芯片,可以根据情况选用。
所述第一转换器621,设置在吸尘器内,与气压检测模块310信号连接, 所述第一转换器621接收所述气压检测模块310的电信号,并将所述电信号转化为反映气压值的数字信号。所述气压检测模块310以及所述第一转换器621具体可以采用多种方式实现,现有技术下已经有多种用于测量气压的包括气压传感器、信号处理电路的气压检测集成电路,可以根据情况选用。这些芯片实际上将所述气压检测模块310与所述第一转换器621集成为一体,实现气压检测并输出可以被所述控制器主控板接收的反映气压值的数字信号。
所述比较器320,设置在控制器内,与第一转换器621信号连接,用于接收所述第一转换器621提供的反映气压值的数字值,并将其与所述比较器320预置的各个临界值进行比较,获得相应的比较结果。
所述第一控制器611一般是控制器610中与气压检测以及根据气压检测进行的控制相关的部分,当然也可以是单独设立的控制单元,在实现方式上可以是控制器610中的相关控制程序、存储的相关参数信息以及运行所述相关控制程序的运算单元;在此使用第一控制器611以便对其独立进行说明。所述第一控制器611用于接收所述比较器320输出的比较结果,并根据比较结果向所述吸尘器的各个执行元件输出相应的控制指令。所述执行元件包括发光显示单元、吸尘电机、报警元件。
在所述第一转换器621输出的已经是数字值的情况下,以上所述比较器320实际上可以将第一转换器621提供的气压检测数值与第一控制器611内包含的主控板(即具有运算和存储功能的微控制单元MCU芯片)内的存储单元中预存的临界值数据比较即可,该比较过程使用所述主控板提供的运算功能即可实现。所述比较结果提供给第一控制器611,所述第一控制器611根据比较结果以及预先设置的程序,即可对相关的执行元件进行控制。
请参考图12,其为本申请实施例控制器工作的流程图;应当说明,该流程图仅仅是根据某个具体的实施方式提供的示意性流程图,其中提供的几个判断步骤在逻辑上并没有先后顺序,即图12流程图中提供的S110、S120、S130、S140即可步骤彼此顺序可以是任意的,也完全可以是并发的;上述步骤S110、S120、S130、S140也可以执行其中任一步骤或者任意的多个步骤, 而不是全部执行。
根据检测到的气压值是否达到某个具体的临界值,第一控制器611可以选择对其中一个执行元件或几个执行元件进行控制,对其他执行元件则不予控制。
S110:检测获得的气压值低于最低允许阈值(第一阈值),对应于该比较结果,所述第一控制器611向吸尘电机发出停机的控制指令,以及向报警元件发出报警启动的控制指令。
该步骤中检测获得的气压值低于最低允许阈值,说明外界空气难以进入,气路已经被严重堵塞,例如进风的风管道或吸尘通道任意部位堵塞,这种情况如果持续过长时间,会造成吸尘电机由于阻力过大而发热,可能烧坏电机以及吸尘器的塑料元件;为此,需要停机以及报警。
若检测获得的气压值高于最高允许阈值(第二阈值),对应于该比较结果,所述第一控制器611向吸尘电机发出停机的控制指令,以及向报警元件发出报警启动的控制指令。
该步骤中检测获得的气压值高于最高允许阈值,说明吸尘器的空气难以出去,气路已经被严重堵塞,例如出风通道或出风口位置堵塞,这种情况如果持续过长时间,也会造成吸尘电机由于阻力过大而发热,可能烧坏电机以及吸尘器的塑料元件;为此,需要停机以及报警。
S120:检测获得的气压值高于最低允许阈值低于正常值,对应于该比较结果,所述第一控制器611向吸尘电机发出增加运行功率的控制指令;
检测获得的气压值高于最低允许阈值低于正常值的情况下,说明进气气路阻力过大,但有可能通过增加吸力恢复吸尘器的正常工作状态,在这种情况下,可以向吸尘电机发出增加运行功率的控制指令,直到所述气压值正常。
检测获得的气压值低于最高允许阈值高于正常值,对应于该比较结果,所述第一控制器611向吸尘电机发出减小运行功率的控制指令;当检测获得的气压值达到正常值后,所述控制器重新控制吸尘电机恢复正常工作。
检测获得的气压值低于最高允许阈值高于正常值的情况下,说明出气气 路阻力过大,但有可能通过减小吸力恢复吸尘器的正常工作状态,在这种情况下,可以向吸尘电机发出减小运行功率的控制指令,直到所述气压值正常。
当检测获得的气压值达到正常值后,所述控制器重新控制吸尘电机恢复正常工作。
S130:滤芯位置检测的气压值低于设定的更换滤芯提示阈值,对应于该比较结果,所述第一控制器611控制输出元件发出需要更换滤芯的提示信息。
本步骤根据滤芯位置的气压值检测结果进行;当滤芯位置的气压值过低时,说明滤芯中积累的灰尘过多,需要更换,此时,第一控制器611可以向输出元件发出提示更换滤芯的控制指令,有输出设备发出提示;具体的提示方式可以根据吸尘器具备的输出方式实现,例如,具有显示屏的吸尘器可以通过显示屏显示,具有语音提示功能的吸尘器可以通过语音提示,还可以根据设置在吸尘器表面上的LED灯的状态提示。
S140:尘桶或马达腔位置的气压值低于设定的尘桶尘满阈值,对应于该比较结果,所述第一控制器611控制输出元件发出需要清理灰尘的提示信息。
该步骤利用尘桶位置的气压检测值检测结果,当该检测结果低于设定的尘桶尘满阈值时,说明尘桶中积攒的灰尘过多,需要清理,所述第一控制器611控制输出元件发出需要清理灰尘的提示信息。
现以一个具体事例说明如下:
最低允许阈值 滤芯提示阈值 尘桶尘满阈值 正常值
20 40 60 90
当检测气压值为10时,提示电机停机以及发出报警信号;
当检测气压值为30时,控制电机增加功率;
当滤芯位置的检测气压值为40时,提示更换滤芯;
当尘桶位置的检测气压值为60时,提示尘桶尘满,需要清理尘桶中的灰尘。
由于不同位置的气压检测值可以通过气压采样气管采样获得,并且现有技术下已经提供了多种可靠便宜的气压检测芯片,因此,可以为一台吸尘器 设置多个检测位置,并根据不同的检测位置的情况具体设置不同的临界值,实现不同的控制效果。
下面介绍本申请的调速控制系统400。
请参照图13,其为本实施例提供的吸尘器调速控制系统的逻辑框图。
本实施例提供的吸尘器调速控制系统400包括:触摸感应件410、功率控制器件420、第二控制器612、第二转换器622。
其中,触摸感应件410,设置在主体的壳体表面,用于响应于触摸操作,生成触摸感应电信号;第二转换器622,与触摸感应件410连接,用于将所述触摸感应电信号转换为能够被所述第二控制器612识别的功率指示信号或转速指示信号。

本实施例可以适用于手持无线吸尘器或传统AC吸尘器,若采用无线吸尘器,对应的电机为直流电机,相应的功率控制器件为MOS管(金属(metal)—氧化物(oxide)—半导体(semiconductor)场效应晶体管)或者IGBT(Insulated Gate Bipolar Transistor),即绝缘栅双极型晶体管;若采用AC吸尘器,对应的电机为串激式电机,相应的功率控制器件为可控硅。触摸感应件可以为FPC触摸膜,感应的触摸感应电信号为电容信号。
本实施例提供的吸尘器调速控制系统,采用了触摸感应件,第二转换器、 第二控制器以及功率控制器件,通过触摸控制的状态的变化,把感应到的触摸感应电信号转化为功率指示信号或者转速指示信号,并通过第二控制器生成功率给定信号或转速给定信号,由功率控制器件控制吸尘电机的导通,获得了对吸尘器进行无级调速的技术效果,提高了用户的体验。
进一步的,触摸感应件可包含:至少两个感应按键及触摸电路。其中,触摸电路,用于在所述至少两个感应按键中一感应控键上存在触摸操作时产生相应触摸感应电信号。所述至少两个感应按键沿一方向依次连续设置。其中,所述触摸电路还用于:当存在从所述至少两个感应按键中的第一感应按键移动至第二感应按键的触摸操作时,产生按时间先后顺序排列的、呈比例变化的多个感应触摸信号。具体的,如图14所示,其为本实施例提供的触摸感应件410的结构示意图,本实施例提供的触摸感应件410包括:感应按键411、独立按键412和输入/输出端子413。
感应按键411由3个以上按键按照一定规则排列组成,感应按键411沿规定方向依次连续设置,各个感应按键411均接出一个信号线到触摸感应件410的输入/输出端子413;输入/输出端子413中还包括感应按键411共用的地线。所述感应按键411可以采用电容感应原理实现触摸检测。
输入/输出端子413提供信号连接,将所述感应按键411和独立按键412的检测结果输出到相关电路或者控制器610,从而使用户在感应按键411上的移动形成的电容变化形成的检测结果转化为对吸尘器进行手动调速的调速指令。所述独立按键412为可以选择设置的按键,该按键与感应按键411间隔设置;通过触摸该独立按键412,可以使吸尘器进入自动调速。
通过所述感应按键411对吸尘器进行手动调速,以及所述独立按键412可以控制吸尘器进入自动调速,获得了对吸尘器自动调速和手动调速的结合的技术效果,有效提升了用户的操作体验。
请参考图14,本实施例提供的感应按键411包括:头部按键411-1,若干中间按键411-2和尾部按键411-3,各个感应按键411的相邻边相互嵌合交接,具体的,相邻边采用锯齿形或者波浪型相互嵌合交接。
例如在图14的实例中,感应按键411的相邻边采用锯齿形相互嵌合交接,图中显示四条锯齿形相邻边,四条锯齿形相邻边之间均为中间按键411-2。具体的,中间按键411-2包括:第一中间按键411-21、第二中间按键411-22和第三中间按键411-23;感应按键411中的各个按键叠合后排列成矩形,相邻按键之间在触摸移动方向上存在逐渐交接代替的截面变化。用户的触摸通过头部按键411-1水平移动至尾部按键411-3,则各个按键获得的电容检测结果,随着接触面积的逐渐变化而逐渐变化,并在各个按键之间转移,从而能够平顺的实现指令输入,从而发出变化平滑的调速指令,根据该调速指令,即可实现对吸尘器吸尘电机的平滑调速。为了方便的对感应按键411的按键状态的变化进行说明,以头部按键411-1向尾部按键411-3的移动方向为例进行说明,实际操作中,用户可以从中间按键411-2向头部按键411-1或者尾部按键411-3移动,移动的方向不做限制。
当手指触碰头部按键411-1时,头部按键411-1具有与手指接触的第一触摸面积(如果头部按键411-1的比例与手指的比例恰当,头部按键411-1会被100%触摸感应),当手指从头部按键411-1向第一中间按键411-21移动时,手指触碰在锯齿形相邻边上,此时头部按411-1的第一触摸面积减少,第一中间按键411-21的触摸面积增加。
利用头部按键411-1与第一中间按键411-21相互嵌合交接的设置,在二者相邻边的交接处,头部按键411-1的第一触摸面积被触摸到的比例在用户移动方向上发生变化,即头部按键411-1的第一触摸面积减小的同时,第一中间按键411-21的触摸面积增加,从而使与输入/输出端子413连接的感应电路(未图示)感应到的感应触摸感应电信号呈现比例的变化;相应的,从第一中间按键411-21向尾部按键411-3移动时,对于相邻边的两个按键,触摸面积也是成比例的变化,通过与输入/输出端子413连接的触摸电路(未图示)感测的触摸感应信号,就可以获知用户滑动的方向以及哪些感应按键411被触摸,使用户感觉到对吸尘器的调速是连贯的,进而获得了平滑的对吸尘器进行无级调速的技术效果。
在一个可选实施例中,尾部按键411-3与头部按键411-1相互电连接,如通过银线将两者连接为同一个按键单元,用户从头部按键411-1滑动至尾部按键411-3时,头部按键411-1和尾部按键411-3依次产生相同的触摸感应电信号,表示一个滑动过程结束。这种方案能增加触摸的准确性和灵敏度,提高用户体验。
在一个可选的实施中,只要在头部按键411-1和尾部按键411-3之间的任意两点之间,按照预定方向滑动,也可以调节功率。当设定从头部按键411-1向尾部按键411-3滑动为增大功率时,在头部按键411-1指向尾部按键411-3的方向上任意依次选取第一点和第二点,当用户从第一点向第二点滑动时为增大功率的滑动调节,当用户从第二点向第一点滑动时为减小功率的滑动调节。因第一点的功率值不等于第二点的功率值,当在头部按键411-1与尾部按键411-3区域之间的任意两点滑动时,都会产生功率的变化,这种变化即为功率的调节。同样的,如果设定从头部按键411-1向尾部按键411-3滑动为减小功率时,两个按键之间的任意两点之间的滑动,都可以改变功率值,这种改变也为调节功率值。这种两点之间的滑动调节功率,用户使用更加便捷,提高了用户体验。
如图15和图16所示,图15为本实施例提供的触摸板的结构示意图,图16为触摸感应件与触摸板的位置关系的示意图;
吸尘器调速控制系统还包括:触摸板430;触摸板430的上部为接收触摸控制的触摸面,触摸感应件410贴在触摸板430的下部;触摸板430能够不影响或者能够帮助触摸感应件410接收直接加载在触摸面上的触摸控制;
可选的,触摸板430上设置有触摸方向图标430-1,用户沿着触摸方向图标430-1的提示方向,在触摸板430上滑动。
可选的,触摸方向图标430-1包括起始图标430-11和终止图标430-12,当触摸感应件410贴在触摸板430的下部时,对应的将触摸感应件410贴在起始图标430-11以及终止图标430-12之间,并且将头部按键411-1与起始图标430-11对应、尾部按键411-3与终止图标430-12对应。用户调速时,手指 在起始图标430-11与终止图标430-12之间进行滑动即可,或者通过接近感应的方式在起始图标430-11与终止图标430-12之间移动,实现对吸尘器的调速。
可选的,触摸板430的材质可以为塑料件、玻璃或者金属镀层。
如图17所示,本申请还提供一种吸尘器,采用如上所述的吸尘器调速控制系统;并且所述吸尘器调速控制系统安置在吸尘器的外表面位置。

下面介绍本申请的调整吸尘电机功率或者转速的方法。
本申请实施例通过提供一种调整吸尘电机功率或者转速的方法,解决了现有技术中单一指标调节电机功率不够准确的技术问题,通过结合至少两个指标,获得电机功率的给定值,实现了准确的调整电机功率。
本申请实施例中的技术方案为解决上述技术问题,总体思路如下:
灰尘检测单元检测到的至少两个灰尘指标输入到吸尘器控制系统中,吸尘器控制系统预先配置好电机功率结合灰尘指标的控制方案,通过判断检测到的灰尘指标是否达到吸尘器控制系统内相应的范围,在该范围内参照电机功率或转速的期待值,控制吸尘电机执行相应的操作,如提升现有功率或减低现有功率,达到电机功率的期待值。需要说明,控制吸尘电机功率还是控制吸尘电机转速,在具体的控制关系上会有一些差别,但是本质是完全一致,功率和转速变化方向是一致的,并且功率和转速的增加对吸尘电机都意味着吸力的增加。为了调整吸尘电机吸力,采用功率调节还是采用转速调节都是可行的,并且控制方案基本一致。
为了更好的理解上述方案,下面将结合说明书附图以及具体的实施方式对上述技术方案进行说明。
请参考图18,其为本申请实施例的调整吸尘器吸尘电机功率的方法流 程图。
本申请实施例的调整吸尘器吸尘电机功率或者转速的方法,包括:
S210:接收灰尘检测单元提供的灰尘指标,所述灰尘指标包含至少两个反映灰尘状况的具体指标;
灰尘检测单元为灰尘传感器,可以是红外传感器、光电传感器或其它类型的传感器,用于检测灰尘通路中的灰尘指标。
灰尘指标具体是指灰尘浓度指标、灰尘颗粒尺寸指标;也可以包括环境气压指标、环境湿度指标或环境温度指标等。灰尘指标用于评价吸尘器工作环境中灰尘的状况,以及与灰尘有关的其他环境情况,并不限于上述列举的具体指标。
S220:使用所述灰尘指标,代入预先确定的吸尘电机功率或转速控制方案,获得吸尘电机功率或者转速的期待值。
本步骤中灰尘指标以灰尘浓度指标和灰尘颗粒指标为例进行说明。
所述预先确定的吸尘电机功率或转速控制方案可以采用多种形式,其中一种为预先确定的多维表格;所述多维表格对应反映灰尘状况的具体指标的数值范围,以及为每一组灰尘指标值设置相应的吸尘电机功率或者吸尘电机转速的数值或者数值范围。
以下是一种灰尘浓度、颗粒大小与电机功率对应关系的多维表格实例:
Figure PCTCN2019105756-appb-000001
通过上述表格记载的内容,当获知灰尘数量(代表灰尘浓度)和灰尘颗 粒尺寸的检测数据后,即可获知电机功率的期待值。
除了表格方式,也可以采用函数方式;以下具体说明一种采用函数方式实现预先确定的吸尘电机功率或转速控制方案的方法。
吸尘电机功率或转速控制方案为预先设定的功率或转速计算函数;包括但不限于以下函数关系:
P=a*T*D 3,P=a(T+D 3),P=aT+bD,P=a(T*D),P=a(T 2+D 2);
其中,a、b为常数,T为灰尘浓度值,D为灰尘颗粒尺寸值;P为功率,公式中的功率P可以改为转速V,此时,根据情况改变a、b常数的数值。
上述计算函数的使用也可以不限于任意一种,也就是说,在调整电机功率的过程中,可以根据情况灵活结合多种方案;以下是具体可以采用的方式:
所述计算函数采用上述功率计算函数中的任意一种,或者分段采用上述功率计算函数中的两种或者多种,或者同时采用上述功率计算函数中的两种或者多种并对各个功率计算函数的计算值加权。
对于上面各个函数中是使用的相关参数,可以根据实验或者吸尘电机的经验公式或者理论公式等方法,确定具体参数的取值。
S230:根据所述吸尘电机功率或者转速的期待值,向吸尘电机控制单元提供相应的给定值。
所述给定值,即为了获得所述期待值,所述控制器需要向所述吸尘电机控制单元提供的指令值,根据该指令值,所述吸尘电机控制单元就能够对所述吸尘电机进行适当的控制,使吸尘电机的功率或者转速在期待值上。根据所需要的电机功率或者转速的期待值,可以根据控制系统的控制关系,推算出需要的给定值,在此不予赘述。
作为一种优选实施方式,可以为电机功率设定上限值P max和下限值P min,在使用预先设定的功率或转速计算函数计算出所述吸尘电机功率后,采用下述分段方式计算需要吸尘电机输出的功率:
Figure PCTCN2019105756-appb-000002
其中,P 为吸尘器吸尘电机实际工作中输出的电机功率的期待值;P为根据计算函数计算获得的吸尘电机功率或者转速的计算值;公式中的P 、P、P min、P max可改为对应的吸尘电机转速相关值V 、V、V min、V max
作为一种优选实施方式,在所述使用所述灰尘指标,代入预先确定的吸尘电机功率或转速控制方案的步骤后,还可以执行以下步骤:
S240:结合所述环境气压指标、环境湿度指标或环境温度指标,对所述获得的数值进行修正,将修正后的数值作为所述吸尘电机功率或者转速的期待值。
该步骤的含义在于,除了灰尘浓度和灰尘颗粒尺寸指标之外,还可以综合考虑其他与吸尘有关的环境指标,例如,在不同的湿度情况下,对于同样的灰尘状况,吸尘器所需要的吸力可能是由很大差别的,在湿度比较大的情况下,需要更大的吸力,在湿度小的情况下,吸力可以小一些。因此,可以根据这些相关指标对于上述使用函数或者表格获得的吸尘电机功率或者转速的期待值进行修正。

下面介绍本申请的提高灰尘检测传感器精度的方法。
本申请实施例通过提供一种提高灰尘检测传感器精度的方法,解决现有技术中灰尘检测传感器在检测灰尘浓度时无法自动对传感器灵敏度校准的问 题,运用自动灰尘检测器发射强度的方式实现了灰尘检测传感器灵敏度的校准。
本申请实施例中的技术方案为解决上述自动校准传感器灵敏度的问题,总体思路如下:
主控板内设置有评价灰尘传感器灵敏度的基准信号VS,该基准信号VS是事先确定的数值,并在灰尘传感器执行当前次灰尘检测工作的过程中为固定的数值;该数值也可以设置有合适的取值区间误差,具体的,根据灰尘检测器当前次检测工作中灵敏度的误差范围确定。
通过将灰尘检测传感器的检测电信号VR输入到主控板,主控板基于传感器接收器211-2输出的检测电信号VR与基准信号VS进行比较,判断两者的关系;在两者的差值不满足预设的阈值区间时,就可以通过调整提供给所述传感器的发射器211-1的电驱动数值(一般采用供电电压),缩小上述两者的差值,直到二者的差值在预先设置的误差范围,则完成校准工作。这样,灰尘传感器在检测灰尘时,若检测电信号VT与基准信号VS不在预设的误差范围,就自动的通过调整灰尘传感器发射器211-1的电驱动,控制发射器211-1的发光强度,从而改变灰尘传感器的检测电信号VR的大小,直到所述检测电信号VR满足预设要求;通过这种调节方式,有效的解决传感器灵敏度自动校准的问题。
需要说明的是,所述检测电信号VR并不是直接用于获得灰尘浓度或者灰尘颗粒尺寸的输出信号,而是从所述接收器211-2直接输出或者仅仅经过简单的放大后的输出信号,在校准环境下,该信号一般会趋于稳定值。例如,所述检测电信号使用电压信号,则发射器211-1的发光强度调整到位后,所述接收器211-2输出的检测电信号VR很快就会稳定;所述检测电信号VR即为所述稳定后的数值。所谓校准环境,就是吸尘器不工作并且环境的灰尘情况正常的情况,该情况下可以对所述传感器进行校正。
上述检测电信号VR以及基准信号VS一般采用电压信号,但是也不排除使用其他形式的电信号,例如电流信号、脉冲信号、方波信号等。
与所述检测电信号VR相对的,是作为灰尘浓度或者灰尘颗粒度尺寸检测依据的灰尘状态检测信号,该灰尘状态检测信号是对检测电信号VR进行放大以及整形后获得的数字方波信号。
为了更好的理解上述技术方案,下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细说明。
请参考图19,其为本申请实施例的提高灰尘检测传感器精度的方法流程图。
本申请实施例的提高灰尘检测传感器精度的方法包括如下步骤:
S310:在校准工作环境下,为所述灰尘检测传感器的发射器211-1提供确定数值的电驱动VT。
所谓校准环境,就是吸尘器不工作并且环境的灰尘情况正常的情况,该情况下可以对所述传感器进行校正。所述电驱动VT为灰尘传感器的发射器211-1提供驱动电力,所述发射器211-1通常为发光二极管,在一定的驱动电压范围内发光。该电驱动VT可以用电压值、电流值、或其他电信号值进行表征;在较多请况下,所述电驱动VT采用电压值。
在本步骤中,电驱动VT是确定数值的含义是在灰尘器传感器的驱动电压范围内的任一电压值,对应的该电驱动VT是校准环境下提供的电压值,提供该电驱动VT与灰尘检测传感器的灵敏度无关,是作为初始的待校准的电压值提供的,故并非是实际工作时的电压值,故可以在传感器的工作特性范围内任意确定。在具体实施方式中,所述电驱动VT由控制器上提供的电压输出端口提供。
S320:接收来自灰尘检测传感器的接收器211-2输出的检测电信号VR;
该检测电信号VR是灰尘传感器的发射器211-1的光信号被接收器211-2接受后得到的信号。如前所述,该信号可以为经过放大器简单放大后的信号;该信号通过控制器内的主控板的输入端口接入主控板,并被主控板读取。
S330:将所述检测电信号VR的数值与预设的基准信号VS的数值比较,判断两者的差值是否在预定的范围内。
所述基准信号VS是预先即可以获知的一个信号值,所述检测电信号VR如果工作在该基准信号VS,则其准确性、稳定性、线性度最好,能够获得最佳的测量效果;所述基准信号VS的具体取值根据传感器的出厂参数确定,或者通过实验测量获得,该数值被记录在控制器的存储器中供读取使用。
由于实际上很难做到检测电信号VR等于所述基准信号VS,可以设置一个围绕所述基准信号VS的数值范围,作为所述检测电信号VR的合理工作区域。为了判断所述检测电信号VR是否在预定范围内,可以将获得的所述检测电信号VR的数值与所述基准信号VS的数值相互之间的差值的绝对值是否小于等于对应所述预定范围的数值来判断,例如,所述基准信号VS=2.4(v),所述预定范围为2.4v±0.1v;则可以使用|VR-2.4|≤0.1来判断所述检测电信号是否符合要求。
S340:若是,则当前提供的所述电驱动VT的数值符合要求,以该数值作为提供给所述灰尘检测传感器的发射器211-1工作的电驱动。
本步骤在所述步骤S330的判断结果为是时执行,此时,根据步骤S330的判断,可以认为目前为发射器211-1提供的电驱动VT的数值是符合要求的,可以使用。本步骤确定采用的电驱动VT往往是经过若干轮调试后的数值;进入本步骤后,就可以结束本次校准过程。
S350:若否,则根据所述检测电信号VR的数值与所述基准信号VS的数值的比较结果,向相反方向调整所述电驱动VT的数值,并返回接收来自灰尘检测传感器的接收器211-2输出的检测电信号VR的步骤。
本步骤在所述步骤S330的判断结果为否时执行,此时,根据步骤S330的判断,可以认为目前为发射器211-1提供的电驱动VT的数值不符合要求,不能直接使用。为此,需要重新提供电驱动VT的数值,并采用新的电驱动VT数值的情况下,返回步骤S320进行新一轮测试。
所述重新提供电驱动VT的数值,需要根据上一步骤S330的比较结果,向相反方向调整所述电驱动VT的数值;所谓向相反方向调整,是指:
若所述检测电信号VR大于所述基准信号VS,则说明所述发射器211-1 的发光亮度需要调低一些,相应的,需要将所述电驱动VT的数值调低;
若所述检测电信号VR小于所述基准信号VS,则说明所述发射器211-1的发光亮度需要调高一些,相应的,需要将所述电驱动VT的数值调高。
上述向相反方向调整所述电驱动VT的数值,实际上仅仅说明了调整的方向,对于实际调整,希望能够尽量直接获得具体的可能数值,以更快的确定电驱动VT的合理取值;为此,可以采用一些计算方法,这些计算方法可以预先设置在控制系统600中,通过控制系统600提供的计算资源计算确定,并通过控制器的输出端口向所述发射器211-1提供计算确定的电驱动VT。
具体进行计算的方法由多种,总体而言,就是将已经执行的前述调试步骤中已经获知的电驱动VT及其对应的检测电信号VR的数值组作为已知取值,求取通过这些数值组的拟合函数,然后,根据拟合函数确定对应理想的检测电信号VR取值的电驱动VT取值。使用上述函数拟合的方法,可以较快获得需要的电驱动VT取值。在具体进行函数拟合的过程中,一般采用线性函数拟合即可,特殊情况下,也可以考虑使用其他函数拟合;例如传感器工作特性曲线为二次函数,则可以考虑使用二次函数拟合。以下以线性函数拟合方式为例说明具体过程。
请参照图20,该图示出上述以函数拟合方式调整电驱动VT的具体方式的流程图。步骤S350中,根据所述检测电信号VR的数值与所述基准信号VS的数值的比较结果,向相反方向调整所述电驱动VT的数值,并返回接收来自灰尘检测传感器的接收器211-2输出的检测电信号VR的步骤具体包括执行如下步骤:
S351:将最近这一轮调试使用的电驱动VT的数值,以及所获得的与之对应的接收器211-2输出的检测电信号VR的数值形成一组数据作为当前数据;
S352:若所述检测电信号VR的数值低于预设的基准信号VS的数值,则根据所述当前数据、以及前面的调整步骤中获得的高于预设的基准信号VS并且距离基准信号VS最近的一组数据,重新建立驱动电压与检测电信号VR 的线性关系;若所述检测电信号VR的数值高于预设的基准信号VS的数值,则根据所述当前数据、以及前面的调整步骤中获得的低于预设的基准信号VS并且距离基准信号VS最近的一组数据,重新建立驱动电压与检测电信号VR的线性关系;
S353:根据所述重新建立的驱动电压与检测信号VR的线性关系,重新获得对应所述基准信号VS的驱动电压VT的数值;
S354:将所述重新获得的对应所述基准信号VS的驱动电压VT的数值作为所述为所述灰尘检测传感器的发射器211-1提供确定数值的电驱动VT步骤中的电驱动VT的数值,并进行后续步骤;
S355:重复上述步骤,直到获得符合要求的驱动电压VT;也就是步骤S330的判断结果为是,进入步骤S340。
请参考图21,其为本申请提供的一种确定电驱动VT的流程图;该确定电驱动VT的方法的特点是利用了传感器的电驱动VT的上限值和下限值;所述上限值和下限值可以根据传感器的出厂参数获得。
具体而言,在步骤S310之前,即所述校准工作环境下,为所述灰尘检测传感器的发射器211-1提供确定数值的电驱动VT之前,包括如下步骤:
S0-301:获得包含驱动电压范围内驱动电压上限电压值、下限电压值分别对应的接收器211-2输出的检测电信号VR的电压值;所述上限电压值对应的检测电信号VR的电压值,以及下限电压值对应的接收器211-2输出的检测电信号VR的电压值可以通过实验测量获得。
S0-302:根据(上限电压值,上限电压值对应的接收器211-2输出的检测电信号VR的电压值),以及(下限电压值,下限电压值对应的接收器211-2输出的检测电信号VR的电压值)两组数据,建立驱动电压与检测电信号VR的函数关系;在采用线性函数时,所述函数关系即为线性关系。
S0-303:根据所述驱动电压与检测电信号VR的函数关系,获得对应所述基准信号VS的驱动电压VT的数值。
S0-304:将对应所述基准信号VS的驱动电压VT的数值,作为所述为所 述灰尘检测传感器的发射器211-1提供确定数值的电驱动VT步骤中的电驱动VT的数值,并进行后续步骤。
现通过如下表格列举数据说明如下:
基准信号VS的电压值为1.4V。
  电压上限 电压下限
驱动电压VT 2V 0.8V
检测电信号VR 1.8V 1.2V
线性关系为:VT=2VR-1.6,将1.4V代入线性关系中:VT=2*1.4-1.6=1.2V;即得出驱动电压VT为1.2V;将驱动电压1.2V作为该确定数值的电驱动VT。
在获得检测电信号时,实际获得的信号是一个包含变化过程的信号,因此,需要确定获取检测电信号的合适取值时机。一般的,可以采用两种方式:
等待所述接收器211-2输出端输出的电压信号稳定后获得的模拟电压信号的数值作为接收器211-2输出的检测电信号;
另一个可选的方式是,待用于表征灰尘状态的所述数字方波信号在规定长度的时间间隔保持个数为0后,将所获得的检测电信号VR的电压值数值作为接收器211-2输出的检测电信号;该方法的实质是利用所述灰尘状态检测信号的情况说明检测电信号已经处于稳定状态。
请参照图22,其为本申请提供的另一种确定电驱动VT的流程图。
所述在非工作状态下,为所述灰尘检测传感器的发射器211-1提供确定数值的电驱动VT之前包括如下步骤:
S1-301:获得第一驱动电压值对应的接收器211-2输出的第一检测电信号VR的电压值,其中,所述第一驱动电压值为驱动电压范围内的任一预估值;
S1-302:获得第二驱动电压值对应的接收器211-2输出的第二检测电信号VR的电压值,其中,所述第二驱动电压值为驱动电压范围内与所述第一驱动电压值不同的值;
S1-303:根据(第一驱动电压值、第一检测电信号VR的电压值),以及(第二驱动电压值、第二检测电信号VR的电压值)两组数据,建立驱动电压与检测电信号VR的线性关系;
S1-304:根据所述驱动电压与检测电信号VR的线性关系,获得对应所述基准信号VS的驱动电压VT的数值;
S1-305:将对应所述基准信号VS的驱动电压VT的数值,作为所述为所述灰尘检测传感器的发射器211-1提供确定数值的电驱动VT步骤中的电驱动VT的数值,并进行后续步骤。
除了上述方案外,也可以将每一轮调试获得的数据均加以利用,以便获得更为精确的拟合函数,此时拟合函数可能不是线性的,或者仅仅是近似线性的,具体处理方式在现有技术下提供了多种可能的处理过程,在此不详细说明;大致而言,其过程如下:
将本轮调试使用的电驱动VT的数值,以及所获得的与之对应的接收器输出的检测电信号VR的数值形成一组数据,将该组数据加入以前各轮调试所获得数据以及初始数据中,形成当前样本数据;
根据所述当前样本数据,重新建立驱动电压VT与检测电信号VR的函数关系;
根据所述重新建立的驱动电压与检测信号VR的线性函数关系,重新获得对应所述基准信号VS的驱动电压VT的推算值;
将所述重新获得的对应所述基准信号VS的驱动电压VT的推算值作为所述为所述灰尘检测传感器的发射器提供确定数值的电驱动VT步骤中的电驱动VT的数值,并进行后续步骤;
重复上述步骤,直到获得符合要求的驱动电压VT。
通过使用上述提高灰尘检测传感器精度的方法,可以有效确保灰尘检测传感器工作在其工作曲线的合适的位置,从而有效提升灰尘检测传感器的工作精度。
