Description

一种低噪音灯具复位控制系统 技术领域
本发明涉及舞台灯技术领域，更具体地，涉及一种低噪音灯具复位控制系统。
 背景技术
舞台灯一般包括枢接于机箱的支撑臂以及枢接于支撑臂的灯头，舞台灯上电复位时或者工作过程中复位时，灯头和/或支撑臂都需要归零明确初始位置，而且在顺、逆时针旋转方向上都会做一个机械的限位结构防止灯具无限的旋转从而扭断里面的电子线。
目前舞台灯的灯头、支撑臂复位时，会先向一个规定的方向旋转灯头、支撑臂直到碰到限位结构不能继续旋转，此时灯头、支撑臂的驱动电机轴也不能继续旋转那么反馈装置就不能正常的反馈信号，系统接收不到反馈装置的正常信号即判定灯具已经到了限位结构的限位位置，将此位置定义为初始位置。
但这个复位方式会有一个比较大的缺陷，由于灯头、支撑臂的质量很大，在以一定速度碰撞限位结构后，会反弹回来，然后在驱动电机的驱动下，再次碰撞限位结构，然后再次反弹，重复这一过程多次，会发出“哒、哒、哒......”的噪音，十分明显。
 技术问题
本发明为克服上述现有技术所述的至少一种缺陷，提供一种低噪音灯具复位控制系统，可以尽量降低灯具复位时的噪音，避免限位部与阻挡部的多次碰撞。
 技术解决方案
为解决上述技术问题，本发明采用的技术方案是：一种低噪音灯具复位控制系统，包括支撑件、枢接于所述支撑件的枢接件以及驱动所述支撑件相对于所述支撑件转动的驱动器；其中所述枢接件包括至少一个用于产生光效的光源，所述枢接件上设置有限位部，所述支撑件上设置有与所述限位部相配合对所述枢接件的旋转角度进行限制的阻挡部；还包括对所述支撑件的旋转角度进行感应的角度检测器以及在所述枢接件相对于所述支撑件处于特定角度位置时发出指示信号的角度指示器，在所述枢接件相对于所述支撑件转动一周的过程中，所述角度指示器仅会发出一次指示信号；在所述灯具复位过程中，当所述枢接件正向转动到所述限位部被所述阻挡部所阻挡时，所述驱动器立刻制动，且驱动所述枢接件低速反向转动一定角度后，再提高速度继续反向驱动所述枢接件转动寻找相对初始位置。
所述低噪音灯具复位控制系统通过所述限位部与所述阻挡部的配合，确定绝对初始位置，然后利用角度指示器确认相对初始位置，并通过角度检测器记录所述枢接件的旋转角度；在所述枢接件正向转动到所述限位部被所述阻挡部所阻挡时，所述驱动器立刻制动，使所述枢接件的转动速度降低，避免使所述限位部重复与所述阻挡部相碰撞发出噪音，然后驱动所述枢接件低速反向转动一定角度，使所述驱动器与所述枢接件之间的传动件得到放松以及所述枢接件的震动减弱，避免造成后面寻找相对初始位置的定位不准确，再提高速度继续反向驱动所述枢接件转动寻找相对初始位置，以完成灯具的复位，既不会多次碰撞发出噪音，初始位置的定位准确度也能够得到保障。
进一步地，所述驱动器立刻制动后，驱动所述枢接件反向转动一定角度直至所述枢接件静止，再继续反向驱动所述枢接件转动寻找相对初始位置。可以使得所述驱动器与所述枢接件之间的传动件得到完全放松以及所述枢接件的震动完全消散，从而使得后面寻找所述枢接件相对初始位置的定位更准确。
进一步地，在所述灯具上电复位时，所述枢接件正向转动直至所述限位部被所述阻挡部所限位，所述驱动器再进行制动并驱动所述枢接件反向转动一定角度，继续反向驱动所述枢接件转动寻找相对初始位置。因为在断电的时候，枢接件会因为各种原因，相对于支撑件旋转，而不被所述角度检测器所记录，所以上电过程中的复位，以所述限位部被所述阻挡部所限位为准。
进一步地，所述枢接件相对于所述支撑件的旋转角度小于360度，当灯具在工作过程中接收到复位指令时，所述驱动器驱动所述枢接件正向转动，直至所述限位部被所述阻挡部所限位或者首次检测到所述角度指示器发出指示信号中任一种情况发生时，就反向驱动所述枢接件转动寻找相对初始位置。如果灯具在工作过程中接收到复位指令时，所述驱动器驱动所述枢接件正向转动的过程中先首次检测到所述角度指示器发出指示信号，则不会发生所述限位部与所述阻挡部碰撞的情况，从而实现无声复位。
进一步地，所述枢接件相对于所述支撑件的旋转角度大于360度且小于720度，当灯具在工作过程中接收到复位指令时，所述驱动器驱动所述枢接件正向转动，直至所述限位部被所述阻挡部所限位或者两次检测到所述角度指示器发出指示信号中任一种情况发生时，就反向驱动所述枢接件转动寻找相对初始位置。如果灯具在工作过程中接收到复位指令时，所述驱动器驱动所述枢接件正向转动的过程中先两次检测到所述角度指示器发出指示信号，则不会发生所述限位部与所述阻挡部碰撞的情况，从而实现无声复位。
进一步地，所述枢接件转动的过程中所述限位部、所述阻挡部互不干扰，所述枢接件的枢接轴上套设有拨杆，所述拨杆可相对于所述枢接轴自由转动，所述限位部、所述阻挡部均可对所述拨杆进行抵持。所述限位部在跟随所述枢接件转动的过程中，其中一周会不带动所述拨杆转动，而另一周会带动所述拨杆转动直至其被所述阻挡部所阻挡，从而实现所述枢接件相对于所述支撑件的旋转角度大于360度且小于720度。
进一步地，所述枢接件的相对初始位置设置在所述枢接件正向转动到所述限位部被所述阻挡部所限位后，反向转动15度的角度范围内。由于该角度范围很窄，所以在灯具工作过程中只有所述枢接件相对于所述支撑件处于某一很小的角度范围内（该范围小于15度），接收到复位指令时，所述驱动器驱动所述枢接件正向转动的过程中，才会先发生所述限位部被所述阻挡部所限位的情况，否则都是先首次（所述枢接件相对于所述支撑件的旋转角度小于360度）或者两次（所述枢接件相对于所述支撑件的旋转角度大于360度且小于720度）检测到所述角度指示器发出指示信号。从而可使得在灯具工作过程中，所述枢接件复位时，大概率发生的都是无声复位。
进一步地，寻找相对初始位置具体为：所述枢接件反向转动过程中，首次经过所述特定角度位置后，所述驱动器驱动所述枢接件再次正向转动，直至第二次经过所述特定角度位置，以第二次经过所述特定角度位置时，所述角度指示器的指示信号产生与结束的中间时刻所述枢接件所处位置为相对初始位置。首次经过所述特定角度位置时，所述枢接件的旋转速度一般都很快，此时无法准确记录所述角度指示器的指示信号产生与结束时间，所以在首次经过所述特定角度位置后，所述枢接件再次正向转动，直至第二次经过所述特定角度位置，以此过程中所述角度指示器的指示信号产生与结束的中间时刻所述枢接件所处位置为相对初始位置，所述相对初始位置的定位更加准确。
进一步地，所述角度指示器的被检测件固定于所述枢接件。被检测件一般不需要连接信号线或者电力线，是独立存在的，所以将所述角度指示器的被检测件固定于所述枢接件，更利于走线设计。
进一步地，所述角度指示器的被检测件为磁性件，检测件为磁开关。以磁检测的方式对相对初始位置进行检测，可以避免环境因素的干扰。
进一步地，所述角度检测器的被检测件固定于所述枢接件。被检测件一般不需要连接信号线或者电力线，是独立存在的，所以将所述角度检测器的被检测件固定于所述枢接件，更利于走线设计。所述角度检测器的被检测件固定于所述枢接件，可以使所述被检测件的结构设计的更大、更密，从而提高检测精度。
进一步地，所述角度检测器的被检测件固定于所述驱动器的转轴。相对于将所述角度检测器的被检测件固定于所述枢接件上，将所述角度检测器的被检测件固定于所述驱动器的转轴上更加容易，结构也更小巧。
进一步地，所述角度检测器的被检测件为光电码盘，所述角度检测器的检测件为光敏接收发器。检测精度高，成本低。
进一步地，所述枢接件为舞台灯的灯头，所述支撑件为舞台灯的支撑臂。
进一步地，所述枢接件为舞台灯灯头和支撑臂，所述支撑件为舞台灯的机箱。

 本发明的最佳实施方式
附图仅用于示例性说明，不能理解为对本专利的限制；为了更好说明本实施例，附图某些部件会有省略、放大或缩小，并不代表实际产品的尺寸；对于本领域技术人员来说，附图中某些公知结构及其说明可能省略是可以理解的。附图中描述位置关系仅用于示例性说明，不能理解为对本专利的限制。
如图1、图2，本发明提供一种低噪音灯具复位控制系统，包括支撑件、枢接于所述支撑件的枢接件以及驱动所述支撑件相对于所述支撑件转动的驱动器200；其中所述枢接件包括至少一个用于产生光效的光源，所述枢接件上设置有限位部510，所述支撑件上设置有与所述限位部510相配合对所述枢接件的旋转角度进行限制的阻挡部520；还包括对所述支撑件的旋转角度进行感应的角度检测器以及在所述枢接件相对于所述支撑件处于特定角度位置时发出指示信号的角度指示器，在所述枢接件相对于所述支撑件转动一周的过程中，所述角度指示器仅会发出一次指示信号；在所述灯具复位过程中，当所述枢接件正向转动到所述限位部510被所述阻挡部520所阻挡时，所述驱动器200立刻制动，且驱动所述枢接件低速反向转动一定角度后，再提高速度继续反向驱动所述枢接件转动寻找相对初始位置。
所述低噪音灯具复位控制系统通过所述限位部510与所述阻挡部520的配合，确定绝对初始位置，然后利用角度指示器确认相对初始位置，并通过角度检测器记录所述枢接件的旋转角度；在所述枢接件正向转动到所述限位部510被所述阻挡部520所阻挡时，所述驱动器200立刻制动，使所述枢接件的转动速度降低，避免使所述限位部510重复与所述阻挡部520相碰撞发出噪音，然后驱动所述枢接件低速反向转动一定角度，使所述驱动器200与所述枢接件之间的传动件得到放松以及所述枢接件的震动减弱，避免造成后面寻找相对初始位置的定位不准确，再提高速度继续反向驱动所述枢接件转动寻找相对初始位置，以完成灯具的复位，既不会多次碰撞发出噪音，初始位置的定位准确度也能够得到保障。
在本实施例中，所述驱动器200立刻制动后，驱动所述枢接件反向转动一定角度直至所述枢接件静止，即速度降为0之后，再继续反向驱动所述枢接件转动寻找相对初始位置。可以使得所述驱动器200与所述枢接件之间的传动件得到完全放松以及所述枢接件的震动完全消散，从而使得后面寻找所述枢接件相对初始位置的定位更准确。
在本实施例中，在所述灯具上电复位时，所述枢接件正向转动时中间不管是否有检测到所述指示信号，都直至所述限位部510被所述阻挡部520所限位，所述驱动器200再进行制动并驱动所述枢接件反向转动一定角度，继续反向驱动所述枢接件转动寻找相对初始位置。因为在断电的时候，枢接件会因为各种原因，例如重力作用或者手动扳动，相对于支撑件旋转，而不被所述角度检测器所记录，所以上电过程中的复位，以所述限位部510被所述阻挡部520所限位为准，复位更准确。
如图3，在本实施例中，所述枢接件相对于所述支撑件的旋转角度小于360度，当灯具在工作过程中接收到复位指令时，所述驱动器200驱动所述枢接件正向转动，直至所述限位部510被所述阻挡部520所限位或者首次检测到所述角度指示器发出指示信号中任一种情况发生时，就反向驱动所述枢接件转动寻找相对初始位置。如果灯具在工作过程中接收到复位指令时，所述驱动器200驱动所述枢接件正向转动的过程中先首次检测到所述角度指示器发出指示信号，则不会发生所述限位部510与所述阻挡部520碰撞的情况，从而实现无声复位。如果先发生所述限位部510被所述阻挡部520所阻挡，则所述驱动器200立刻制动，且驱动所述枢接件低速反向转动一定角度后，再提高速度继续反向驱动所述枢接件转动寻找相对初始位置，此时仅会发生一次碰撞。优选地，此时所述枢接件为舞台灯的灯头110，所述支撑件为舞台灯的支撑臂120。
如图4、图5，在本实施例中，所述枢接件相对于所述支撑件的旋转角度大于360度且小于720度，当灯具在工作过程中接收到复位指令时，所述驱动器200驱动所述枢接件正向转动，直至所述限位部510被所述阻挡部520所限位或者两次检测到所述角度指示器发出指示信号中任一种情况发生时，就反向驱动所述枢接件转动寻找相对初始位置。如果灯具在工作过程中接收到复位指令时，所述驱动器200驱动所述枢接件正向转动的过程中先两次检测到所述角度指示器发出指示信号，则不会发生所述限位部510与所述阻挡部520碰撞的情况，从而实现无声复位。如果先发生所述限位部510被所述阻挡部520所阻挡，则所述驱动器200立刻制动，且驱动所述枢接件低速反向转动一定角度后，再提高速度继续反向驱动所述枢接件转动寻找相对初始位置，此时仅会发生一次碰撞。优选地，此时所述枢接件为舞台灯灯头110和支撑臂120，所述支撑件为舞台灯的机箱130。
在本实施例中，所述枢接件转动的过程中所述限位部510、所述阻挡部520互不干扰，所述枢接件的枢接轴140上套设有拨杆530，所述拨杆530可相对于所述枢接轴140自由转动，所述限位部510、所述阻挡部520均可对所述拨杆530进行抵持。所述限位部510在跟随所述枢接件转动的过程中，其中一周会不带动所述拨杆530转动，而另一周会带动所述拨杆530转动直至其被所述阻挡部520所阻挡，从而实现所述枢接件相对于所述支撑件的旋转角度大于360度且小于720度。
在本实施例中，所述枢接件的相对初始位置设置在所述枢接件正向转动到所述限位部510被所述阻挡部520所限位后，反向转动15度的角度范围内。由于该角度范围很窄，所以在灯具工作过程中只有所述枢接件相对于所述支撑件处于某一很小的角度范围内（该范围小于15度），接收到复位指令时，所述驱动器200驱动所述枢接件正向转动的过程中，才会先发生所述限位部510被所述阻挡部520所限位的情况，否则都是先首次（所述枢接件相对于所述支撑件的旋转角度小于360度）或者两次（所述枢接件相对于所述支撑件的旋转角度大于360度且小于720度）检测到所述角度指示器发出指示信号。从而可使得在灯具工作过程中，所述枢接件复位时，大概率发生的都是无声复位。
在其它实施例中，所述枢接件的相对于所述支撑件的旋转角度范围可以更大，如果灯具在工作过程中接收到复位指令时，所述驱动器200驱动所述枢接件正向转动的过程中先N+1次检测到所述角度指示器发出指示信号，其中N为所述枢接件的最大旋转角度除以360之后得到的整数，则不会发生所述限位部510与所述阻挡部520碰撞的情况，从而实现无声复位。
在本实施例中，寻找相对初始位置具体为：所述枢接件反向转动过程中，首次经过所述特定角度位置后，所述驱动器200驱动所述枢接件再次正向转动，直至第二次经过所述特定角度位置，以第二次经过所述特定角度位置时，所述角度指示器的指示信号产生与结束的中间时刻所述枢接件所处位置为相对初始位置。首次经过所述特定角度位置时，所述枢接件的旋转速度一般都很快，此时无法准确记录所述角度指示器的指示信号产生与结束时间，所以在首次经过所述特定角度位置后，所述枢接件再次正向转动，直至第二次经过所述特定角度位置，以此过程中所述角度指示器的指示信号产生与结束的中间时刻所述枢接件所处位置为相对初始位置，所述相对初始位置的定位更加准确。
在本实施例中，所述角度指示器的被检测件固定于所述枢接件。被检测件一般不需要连接信号线或者电力线，是独立存在的，所以将所述角度指示器的被检测件固定于所述枢接件，更利于走线设计。可选地，所述角度指示器的被检测件固定于所述枢接件的枢接轴140上。
在本实施例中，所述角度指示器的被检测件为磁性件310，检测件为磁开关320。以磁检测的方式对相对初始位置进行检测，可以避免环境因素的干扰。在其它实施例中，所述角度指示器也可以为机械开关或者观点开关。

在本实施例中，所述角度检测器的被检测件固定于所述驱动器200的转轴210。相对于将所述角度检测器的被检测件固定于所述枢接件上，将所述角度检测器的被检测件固定于所述驱动器200的转轴210上更加容易，结构也更小巧。
在本实施例中，所述角度检测器的被检测件为光电码盘410，所述角度检测器的检测件为光敏接收发器420。检测精度高，成本低。在其它实施例中，所述角度检测器也可以为电阻式角度传感器，电容式角度传感器，霍尔式角度传感器、光电式角度传感器或红外式角度传感器等，不局限于磁编码式角度传感器。
在本实施例中，所述限位部510、所述阻挡部520由分别由固定在所述枢接件、所述支撑件上的螺柱形成。
