具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下面结合附图来描述本发明实施例的风扇及其摇头控制方法。
图1为根据本发明实施例的风扇的摇头控制方法的流程图。
如图1所示,本发明实施例的风扇的摇头控制方法,包括以下步骤:
S1,当风扇进入人感模式后,通过控制摇头机构以使风扇扫描检测预设的角度范围内是否有人。
本发明实施例的风扇具有摇头机构,风扇可通过摇头机构控制转动以扩大送风范围。在风扇未进入人感模式时,风扇可在预设的角度范围内进行转动,也可在用户任意设定的角度范围内进行转动。
在本发明的一个实施例中,可通过对风扇本体上的按键操作或对遥控器的操作来控制风扇进入人感模式。例如,可在风扇开启后按下遥控器的“人感”键以开启人感模式,风扇及遥控器显示面板上的“人体感应”指示灯亮。再次按下遥控器“人感”键则可关闭人 感模式,显示面板上的“人体感应”指示灯熄灭。在风扇开启时,可默认为人感模式关闭,在人感模式下风速可以调节,但风扇的摇头角度不可调节。
在进入人感模式后,风扇可进行人体感应,具体可通过控制摇头机构以使风扇扫描检测预设的角度范围内是否有人。如图2所示,预设的角度范围可包括120度的角度范围,在人体感应模式首次开启后,摇头机构可控制风扇由当前位置摆到下限值0度位置,之后从0度向上限值120度位置移动扫描,到120度位置停止,期间人体感应指示灯闪烁。
在本发明的一个实施例中,可通过红外传感器扫描检测预设的角度范围内是否有人,具体地,可判断红外传感器所接收到的红外辐射量是否大于预设阈值。如果红外传感器所接收到的红外辐射量大于预设阈值,则判定风扇主体的前方有人;如果红外传感器所接收到的红外辐射量小于或等于预设阈值,则判定风扇主体的前方无人。
S2,如果预设的角度范围内有人,则获取每个人的位置,并获取每个人的位置相对预设位置的角度值。
其中,预设位置作为确定每个人的角度值的基准位置,可为预设的角度范围中的任一角度值所对应的位置。例如,可以为预设的角度范围的上限值或下限值所对应的位置,或者预设的角度范围的中间值所对应的位置。当然,预设位置也可为任意的能够表示每个人在预设的角度范围中相对位置的其他位置。
在本发明的一个实施例中,预设位置可为上述的0度所对应的位置。由此,每个人在上述的0至120度的角度范围内可具有对应的0至120度之间的角度值。
S3,判断角度值是否为多个。
S4,如果角度值为多个,则根据多个角度值获取第一位置和第二位置,并通过控制摇头机构以使风扇在第一位置对应的角度值与第二位置对应的角度值之间进行来回转动,其中,第一位置为最接近预设的角度范围的上限值所对应的位置,第二位置为最接近预设的角度范围的下限值所对应的位置。
也就是说,如果预设的角度范围内有人,并且人的位置对应多个角度值,则获取最靠近预设的角度范围的上限值的角度值对应的位置,并获取最靠近预设的角度范围的下限值的角度值对应的位置。
在本发明的一个实施例中,当预设位置为预设的角度范围的上限值或下限值所对应的位置时,如果角度值为多个,则第一位置为多个角度值中的最大角度值所对应的位置,第二位置为多个角度值中的最小角度值所对应的位置。在根据预设位置确定角度值后,可通过控制摇头机构以使风扇在多个角度值中的最大角度值和最小角度值所对应的位置之间进行来回转动,使风扇将根据左右两侧最边缘的人形成的角度范围作为新的转动范围。也就是说,当多个人在不同角度值对应的位置时,风扇可在最左边和最右边的人之间来回转动 送风,而不会向最左边和最右边的人之间的角度之外的位置送风。
在本发明的一个实施例中,当角度值为一个时,可通过控制摇头机构以使风扇的出风方向正对该角度值对应的位置。由此,能够对该角度值对应的位置持续送风。
在本发明的一个实施例中,在风扇进入人感模式后,可每间隔第一预设时间控制风扇扫描检测一次,以检测人员的位置是否发生变化。在人员的位置发生变化时,可通过上述步骤重新进行摇头控制。
此外,当预设的角度范围内无人时,可通过控制摇头机构以使风扇在预设的角度范围内进行转动,并在连续第二预设时间内均未检测到预设的角度范围内有人时,控制风扇停止工作。具体地,在人体感应模式开启后,如果未检测到人,则风扇一直处于扫描检测状态,即摇头机构控制风扇从0度到120度再到0度循环扫描,人体感应指示灯闪烁,如果连续5分钟未检测到有人,则关闭风叶驱动电机。由此,可避免风扇在无人时转动而造成的能源浪费。
根据本发明实施例的风扇的摇头控制方法,通过扫描检测预设的角度范围内是否有人,在预设的角度范围内有人时可获取每个人的位置相对预设位置的角度值,并在角度值为多个时,控制风扇在多个角度值中两侧的角度值之间进行来回转动,由此,可根据用户的实际需要调整风扇的摇头角度,能够合理利用能源,即能够提高风扇的工作效率、降低风扇的能耗,从而提升了用户的体验度。
为实现上述实施例的风扇的摇头控制方法,本发明还提出一种风扇。
如图3所示,本发明实施例的风扇,包括摇头机构10、检测模块20、获取模块30、判断模块40和控制模块50。
其中,检测模块20用于在风扇进入人感模式后,通过控制摇头机构10以扫描检测预设的角度范围内是否有人;获取模块20用于在预设的角度范围内有人时,获取每个人的位置,并获取每个人的位置相对预设位置的角度值;判断模块30用于判断角度值是否为多个;控制模块40用于在角度值为多个时,根据多个角度值获取第一位置和第二位置,并通过控制摇头机构以使风扇在第一位置对应的角度值与第二位置对应的角度值之间进行来回转动,其中,第一位置为最接近预设的角度范围的上限值所对应的位置,第二位置为最接近预设的角度范围的下限值所对应的位置。
本发明实施例的风扇可通过摇头机构控制转动以扩大送风范围。在风扇未进入人感模式时,风扇可在预设的角度范围内进行转动,也可在用户任意设定的角度范围内进行转动。
在本发明的一个实施例中,可通过对风扇本体上的按键操作或对遥控器的操作来控制风扇进入人感模式。例如,可在风扇开启后按下遥控器的“人感”键以开启人感模式,风扇及遥控器显示面板上的“人体感应”指示灯亮。再次按下遥控器“人感”键则可关闭人 感模式,显示面板上的“人体感应”指示灯熄灭。在风扇开启时,可默认为人感模式关闭,在人感模式下风速可以调节,但风扇的摇头角度不可调节。
在进入人感模式后,风扇可进行人体感应,具体可通过控制摇头机构以使风扇扫描检测预设的角度范围内是否有人。如图2所示,预设的角度范围可包括120度的角度范围,在人体感应模式首次开启后,摇头机构可控制风扇由当前位置摆到下限值0度位置,之后从0度向上限值120度位置移动扫描,到120度位置停止,期间人体感应指示灯闪烁。
在本发明的一个实施例中,检测模块20可包括红外传感器,具体地,检测模块20可判断红外传感器所接收到的红外辐射量是否大于预设阈值。如果红外传感器所接收到的红外辐射量大于预设阈值,则判定风扇主体的前方有人;如果红外传感器所接收到的红外辐射量小于或等于预设阈值,则判定风扇主体的前方无人。
需要说明的是,预设位置作为确定每个人的角度值的基准位置,可为预设的角度范围中的任一角度值所对应的位置。例如,可以为预设的角度范围的上限值或下限值所对应的位置,或者预设的角度范围的中间值所对应的位置。当然,预设位置也可为任意的能够表示每个人在预设的角度范围中相对位置的其他位置。
在本发明的一个实施例中,预设位置可为上述的0度所对应的位置。由此,每个人在上述的0至120度的角度范围内可具有对应的0至120度之间的角度值。
如果预设的角度范围内有人,并且人的位置对应多个角度值,则控制模块50可获取最靠近预设的角度范围的上限值的角度值对应的位置,并获取最靠近预设的角度范围的下限值的角度值对应的位置。
在本发明的一个实施例中,当预设位置为预设的角度范围的上限值或下限值所对应的位置时,如果判断模块40判断角度值为多个,则控制模块50获取的第一位置为多个角度值中的最大角度值所对应的位置,第二位置为多个角度值中的最小角度值所对应的位置。在根据预设位置确定角度值后,控制模块50可通过控制摇头机构以使风扇在多个角度值中的最大角度值和最小角度值所对应的位置之间进行来回转动,使风扇将根据左右两侧最边缘的人形成的角度范围作为新的转动范围。也就是说,当多个人在不同角度值对应的位置时,风扇可在最左边和最右边的人之间来回转动送风,而不会向最左边和最右边的人之间的角度之外的位置送风。
在本发明的一个实施例中,当角度值为一个时,控制模块50可通过控制摇头机构以使风扇的出风方向正对该角度值对应的位置。由此,能够对该角度值对应的位置持续送风。
在本发明的一个实施例中,在风扇进入人感模式后,检测模块20可每间隔第一预设时间控制风扇扫描检测一次,以检测人员的位置是否发生变化。在人员的位置发生变化时,可通过上述装置重新进行摇头控制。
此外,当预设的角度范围内无人时,控制模块50可通过控制摇头机构以使风扇在预设的角度范围内进行转动,并在连续第二预设时间内均未检测到预设的角度范围内有人时,控制风扇停止工作。具体地,在人体感应模式开启后,如果未检测到人,则风扇一直处于扫描检测状态,即摇头机构控制风扇从0度到120度再到0度循环扫描,人体感应指示灯闪烁,如果连续5分钟未检测到有人,则关闭风叶驱动电机。由此,可避免风扇在无人时转动而造成的能源浪费。
根据本发明实施例的风扇,通过检测模块扫描检测预设的角度范围内是否有人,获取模块在预设的角度范围内有人时可获取每个人的位置相对预设位置的角度值,在角度值为多个时,控制模块可控制风扇在多个角度值中两侧的角度值之间进行来回转动,由此,可根据用户的实际需要调整风扇的摇头角度,能够合理利用能源,即能够提高风扇的工作效率、降低风扇的能耗,从而提升了用户的体验度。
