本发明涉及舞台照明技术领域，尤其涉及一种无线电力传输及无线通讯的舞台灯光万向切割系统。
 背景技术
 随着灯光技术的不断发展，观众对于灯光演绎效果的要求也越来越高。为了让观众观赏到更加精美更加漂亮的灯光效果，而在舞台灯中，需要用到光束切割造型装置来切割光束，使之形成不同的光影特效。在舞台灯中经常需要将光束切割造型装置不断旋转，以获取更多层次更丰富的灯光效果。但是，传统的舞台灯转动的角度有限，而且旋转一定角度后还会导致舞台灯中的电线互相缠绕，导致舞台灯失灵的情况出现。为了解决这一问题，专利CN201620360678，公开了一种光束切割造型旋转结构及舞台灯。该光束切割造型旋转结构，包括环形造型固定支架，固定于所述造型固定支架一侧的支架盖板，转动连接于所述造型固定支架另一侧的切割造型机构，以及设置于所述造型固定支架中间的导电滑环，所述导电滑环一侧固定于所述支架盖板而另一侧连接于所述切割造型机构。该技术通过导电滑环中的第一导电板与第二导电板实现滑动电连接，但是在实际操作过程中，由于第一导电板与第二导电板是要相互接触的，所以在高速旋转的过程中，第一导电板与第二导电板会发生摩擦并且放出大量的热量。因此，该技术容易导致第一导电板与第二导电板磨损，使得第一导电板与第二导电板接触不良，使用寿命较短；其次在使用过程中大量的能量转换为热能，加大能耗的同时为了避免转速过快产生大量热量而引发事故而限制旋转的速度；再加上由于第一导电板与第二导电板必须接触，因此导电滑环的两端不能距离太远，否则造价与实施难度会大幅度提高。
 技术问题
本发明的目的在于，提供一种能够实现无接触式的无线电力传输及无线通讯的舞台灯光万向切割系统。
 技术解决方案
为实现上述目的，本设计发明提供如下技术方案：
一种无线电力传输及无线通讯的舞台灯光万向切割系统包括旋转盘支架、与旋转盘支架固定连接的固定支架、无线供电装置以及与旋转盘支架转动连接的切割造型机构，所述切割造型机构用于拦截切割光束以获得不同的灯光效果，且由第一驱动装置驱动进行角度无限旋转；所述切割造型机构上还设有用于驱动其上切割造型片动作的第二驱动装置；所述无线供电装置包括电磁场发射装置以及电磁场接收装置，所述固定支架上设有电磁场发射装置，所述切割造型机构上设有电磁场接收装置，所述电磁场接收装置向第二驱动装置输送电力；所述舞台灯光万向切割系统还包括无线信号发射装置，所述切割造型机构还设有与无线信号发射装置相匹配的无线信号接收装置。
本发明通过设置电磁场发射装置与电磁场接收装置，使得不需要线缆也不需要切割造型机构与固定支架接触就可以向切割造型机构输送源源不断的电力，实现切割造型机构的无线电力供应。因此，本发明有以下优势：第一，避免切割造型机构与固定支架由于相互旋转摩擦导致的磨损，提高整个系统的使用寿命；第二，由于避免了切割造型机构与固定支架相互旋转所带来的摩擦热，所以极大程度地提高整个系统的能源利用效率，而且同时解开了切割造型机构的旋转速度的束缚，可以采用更高的速度来展示更加丰富的灯光效果；第三、摆脱了切割造型机构与固定支架之间的距离限制，方便工作人员根据需要设计系统，如设置多个切割造型机构来展示不同的光影特效。而且本发明还设置无线信号发射装置以及无线信号接收装置，一是为了向电磁场接收装置与电磁场发射装置发送充电信息来及时调整充电效果，二是为了允许人们可以将外设的控制面板（即舞台灯的控制面板）与无线信号发射装置通过电缆信号连接，通过外设的控制面板来调整切割造型机构的旋转速度与光束切割方式，以展示不同的灯光效果，相比起通过总控制端的总无线信号发射装置发送信号的方式，无线信号发射装置与无线信号接收装置可以采用传输距离较短但成本也相对较低的蓝牙、红外线等传输装置，减少成本；而且同样避免总无线信号发射装置同时给若干无线信号接收装置发送信号，导致信号混乱的现象出现。
优选地，所述切割造型机构上设有电机控制装置，所述电机控制装置分别与电磁场接收装置、第二驱动装置和无线信号接收装置信号连接。所述电机控制装置为单片机、电机驱动电路等。
设置电机控制装置是为了更好地控制电磁场接收装置输出电量，以符合驱动装置以及切割造型机构的运作，配合光源制作出漂亮美观的光影效果。
更加优选地，所述舞台灯万向切割系统设有若干无线信号发射装置，所述无线信号发射装置优选地设置在所述固定支架上，所述切割造型机构上设有与无线信号发射装置匹配的若干无线信号接收装置。
由于通过无线电力传输时会产生出强大的磁场，容易影响到无线信号发射装置的信息传播，为了提高无线通信的可靠性，本专利采取了两套独立的无线通信单元，以第一通信单元为主通信单元，第二通信单元为备份通信单元，当主通信单元出现故障或者噪音过大时，切换到第二通信单元，硬件上的冗余设计提高了无线通信的可靠性。
优选地，所述无线信号发射装置与所述无线信号接收装置设有控制器MCU。
通过运用控制器MCU调节无线信号发射装置与无线信号接收装置的发射频率，使之能单独匹配，或者通过控制器MCU设定特定的识别ID，也能使得无线信号发射装置与所述无线信号接收装置只能单独匹配，不会影响到其它装置。
优选地，所述电磁场接收装置与电磁场发射装置通过磁共振或电磁感应的方式进行无线电力传输。
由于电磁感应的无线电力传输方式简单，所以对于无线充电装置的要求降低，需要的设备简单，而且电磁场接收装置与电磁场发射装置的距离短完全符合电磁感应无线电力传输方式。而磁共振方式相比起电磁感应方式，最大区别是是否设置有振荡器，通过振荡器使得电磁场接收装置与电磁场发射装置产生谐振效应，传输效率更高，传输功率更大。
优选地，所述无线信号发射装置与无线信号接收装置通过高频信号传输信息。
优选地，所述切割造型机构包括与旋转盘支架转动连接的切割造型支架以及设置在切割造型支架上的切割造型主体。
优选地，所述电磁场发射装置包括电磁场发射线圈、用于安装电磁场发射线圈的安装组件一、用于控制电磁场发射线圈发射功率的电磁场发射及无线控制电路板；所述电磁场接收装置包括电磁场接收线圈、用于安装电磁场接收线圈的安装组件二、用于将电磁场接收线圈输出的交流电流转换为直流的电磁场接收及无线控制电路板。
更加优选地，所述电磁场发射及无线控制电路板包括用于将直流电转换成交流电流的振荡器，所述电磁场发射装置还包括功率控制电路以及滤波器，外部电流进入到电磁场发射装置后，依次经过振荡器、功率控制电路、滤波器以及电磁场发射线圈，使得电磁场发射线圈创造一个变化的强磁场，电磁场接收线圈通过电磁感应将强磁场转换为交流电流。
为了减少噪音的干扰，提高功率传输的动态反应度，本发明通过设置功率控制电路采集电磁场发射线圈瞬间输出电流及电压情况然后调整输出脉冲的占空比来满足负载的动态变化以及设置滤波器来去除电路中的噪音。
优选地，所述固定支架设有固定件，所述安装组件一固定在所述固定件上，所述安装组件一呈环形状，所述电磁场发射线圈嵌套在所述安装组件一的内部。
优选地，所述安装组件二也可以呈环形状，所述电磁场接收线圈嵌套在所述安装组件二的内部，所述安装组件二固定在所述切割造型机构上。
更加优选地，所述无线信号发射装置包括无线控制器和发射天线，所述发射天线与无线控制器可均设在所述电磁场发射及无线控制电路板上或所述发射天线设于安装组件一上，所述无线控制器设在所述电磁场发射及无线控制电路板上。
更加优选地，所述无线信号接收装置包括无线控制器和接收天线，所述接收天线与无线控制器均设在所述电磁场接收及无线控制电路板上或所述接收天线设于安装组件二上，所述无线控制器设在所述电磁场接收及无线控制电路板上。
当所述发射天线设于电磁场发射线圈的安装组件一上，所述接收天线设于电磁场接收线圈的安装组件二上时，所述发射天线和接收天线为环形，所述环形天线的中心轴重合，在角度无限旋转过程中，所述环形天线的中心轴保持重合不变。
优选的安装方法为，所述安装组件一上设有第一环形延伸侧壁，所述安装组件二上设有第二环形延伸侧壁，所述发射天线设于第一环形延伸侧壁上，所述接收天线设于第二延伸侧壁上，且安装组件一与安装组件二安装配合时，两天线相对设置。现有技术的两天线是分别设置在旋转盘支架和切割造型支架的两个点位置上的，当旋转盘支架和切割造型支架相对旋转时，会使得两个天线位置时而出现在相对远的位置，从而造成信号不稳定；另外，对于并排设置的舞台灯，甚至会出现相邻舞台灯的天线距离比同一舞台灯的天线距离更近，从而发现信号串扰的现象，本方案通过这种发射天线和接收天线环形相对设置，能使得信号更为稳定，避免天线信号发生串扰，从而发生误操作，保持信号畅通。
为进一步减少磁场线圈对舞台灯内其他电器件的影响，尤其是切割造型支架上的电机的影响，所述安装组件一上用于安装电磁场发射线圈的第一嵌套内腔与所述安装组件二用于安装电磁场接收线圈的第二嵌套内腔部分叠套，使电磁场发射线圈与电磁场接收线圈充分接近。如此设计之后，能使得线圈的电能传递更为充分，避免磁能的往外辐射。
为了进一步减少电磁场对其他设备的影响，所述第一嵌套内腔在电磁场发射线圈和所述第二嵌套内腔在电磁场接收线圈周边均设有磁铁，大大加强了电能的传递效率。
优选地，所述第一驱动装置包括设置在固定支架或旋转盘支架上的驱动电机以及与驱动电机连接的主动轮，在切割造型机构上设有与主动轮连接的从动轮，所述驱动电机驱动主动轮和从动轮进行角度无限旋转。
作为替代方案，所述第一驱动装置包括设置在切割造型机构上的驱动电机以及与驱动电机连接的主动轮，在旋转盘支架上设有与主动轮连接的从动轮，所述驱动电机驱动主动轮和从动轮进行角度无限旋转。
所述主动轮及从动轮优选为360°旋转齿轮，可实现角度无限旋转。
本发明还涉及一种舞台灯，包括光源，以及与所述光源相对应的上述的无线电力传输及无线通讯的舞台灯光万向切割系统。光源发出的光束经过切割造型机构的中空孔时，切割造型机构可以一边旋转一边对光束进行切割造型，旋转角度不受限制，可以实现更加广泛的灯光造型，实现更好的灯光效果。优选地，所述舞台灯还包括用于控制光源以及所述舞台灯光万向切割系统的控制面板。
 有益效果
相比起现有技术，本发明的有益效果为：
1.    本发明通过设置电磁场发射装置与电磁场接收装置能有效避免切割造型机构旋转时带动线缆，从而令得切割造型机构能有更大的旋转自由度，实现更加丰富的光束切割效果。
2.    设置有无线信号发射装置以及无线信号接收装置，一方面能通过信号传输来了解切割造型机构的转速、功率等因素，及时调整电能传输效果，二是为了允许人们可以通过外设的显示控制面板（即舞台灯的控制面板）来调整切割造型机构的旋转速度与光束切割方式，以展示不同的灯光效果。
