Description
本申请涉及雷达技术领域,尤其涉及一种雷达装置、雷达的无线旋转装置及无人机。
随着无人机技术的飞速发展及雷达小型化技术的提高,雷达逐渐成为无人机载荷的重要组成部分,而天线组件作为雷达的核心元件,其在雷达工作时,受驱动机构,例如电机驱动作用,可绕一转轴进行旋转,以探测不同方向上的障碍物。现有技术中,采用线缆连接天线组件与外部电源,以对天线组件进行供电,然而,在此种供电方式下,由于线缆的限制,将导致驱动机构的旋转角度有限,例如旋转角度仅能达到270°,从而无法实现天线组件进行360°全向旋转。
发明内容
有鉴于此,本申请公开了一种雷达装置、雷达的无线旋转装置及无人机。
根据本申请实施例的第一方面,提供一种雷达装置,所述装置包括:底座;天线组件,设于所述底座,所述天线组件相对于所述底座绕一转轴旋转;电能发射组件,用于将电能转换为电磁能,并发射所述电磁能;电能接收组件,与所述电能发射组件间隔设置;其中,所述电能接收组件,与所述天线组件电连接,并与所述天线组件一起旋转,用于将接收到的电磁能转换为电能,并将转换后的电能传输给所述天线组件。
根据本申请实施例的第二方面,提供一种雷达的无线旋转装置,所述装置包括:底座;天线组件,设于所述底座,所述天线组件相对于所述底座绕一转轴旋转;电能发射组件,用于将电能转换为电磁能,并发射所述电磁能;电能接收组件,与所述电能发射组件间隔设置;其中,所述电能接收组件,与所述天线组件电连接,并与所述天线组件一起旋转,用于将接收到的电磁能转换为电能,并将转换后的电能传输给所述天线组件。
根据本申请实施例的第三方面,提供一种无人机,所述无人机包括:机架;负载;及雷达装置,安装于所述机架和所述负载的其中一者上,包括:底座;天线组件,设于所述底座,所述天线组件相对于所述底座绕一转轴旋转;电能发射组件,用于将电能转换为电磁能,并发射所述电磁能;电能接收组件,与所述电能发射组件间隔设置;其中,所述电能接收组件,与所述天线组件电连接,并与所述天线组件一起旋转,用于将接收到的电磁能转换为电能,
并将转换后的电能传输给所述天线组件。
由上述实施例可见,通过将电能发射组件固定安装于底座,将电能接收组件与天线组件电连接,并设置为同天线组件一起旋转,进一步基于电磁感应原理,可以实现电能发射组件将接收到的直流电能转换为电磁能,并发射该电磁能,电能接收组件则将接收到的电磁能转换为直流电能,将该直流电能传输给与其电连接的天线组件,也即实现了对天线组件进行无线供电。在此种供电方式下,由于无需设置线缆以连接天线组件与外部电源,也即消除了线缆的限制,从而可以使得电机实现360°全向旋转,继而驱动天线组件实现360°全向旋转,以更好地探测不同方向上的障碍物。

首先,通过下述实施例一对本申请提供的雷达装置进行详细说明:
实施例一
请参见图1及图2,分别为本申请实施例提供的一种雷达装置100的结构示意图与剖视图,如图1及图2所示,该雷达装置100中包括底座110、天线组件120、用于支撑天线组件120
的天线支架140、电机130,以及电能发射组件200与电能接收组件300。
其中,如图1所示,天线组件120设于底座110,其可相对于底座110绕一转轴旋转,需要说明的是,该转轴可以为实轴,也可以为虚轴,当该转轴为实轴时,天线组件120可相对于该转轴旋转,或者,天线组件120跟随该转轴一起旋转。电机130设于底座110上,其可以包括与天线组件120连接的转子131,可用于驱动天线支架140转动,使得天线组件120随着天线支架140一起绕前述转轴进行旋转。电能接收组件300与电能发射组件400间隔设置。电能接收组件与天线组件120电连接,并可与天线组件120一起旋转。电能接收组件可以与电能发射组件共同配合,向天线组件120提供电能,以使天线组件120正常工作。
如下,结合附图,对电能接收组件与电能发射组件各自的结构,以及该两者共同配合,向天线组件120提供电能的具体实现原理、实现过程进行详细描述。
首先说明,结合上述图1及图2所示例的雷达装置100,电能发射组件200可以固定设置于上述图1所示例的底座110上,电能接收组件可以固定安装于上述天线支架140,随着天线组件一起旋转。
其次,对电能发射组件、电能接收组件各自的结构及各自的工作原理,工作过程进行描述。
请参见图3,为图1所示的雷达装置的电能发射组件200与电能接收组件300的结构示意图。
如图3所示,电能发射组件200可以包括供电电路板210、发射端控制芯片220、发射端电流调整电路230,以及发射线圈240。
其中,供电电路板210与发射端控制芯片220、发射端电流调整电路230电连接,其可以向发射端控制芯片220及发射端电流调整电路230进行供电。在本实施例中,该供电电路板210提供的电流为直流电,该直电流的大小可以是恒定的,也可以是动态变化的,本申请对此不作限制。发射端控制芯片220与发射端电流调整电路230电连接,其可以用于控制发射端电流调整电路230将接收到的直流电能转换为预设频率范围的交流电能。
进一步,发射端电流调整电路230与发射线圈240电连接,其可以将转换后的交流电能传输给发射线圈240。进一步,发射线圈240则可以将接收到的交流电能转换为电磁能,并发射该电磁能。
为了实现将直流电能转换为预设频率范围的交流电能,在一实施例中,上述发射端电流调整电路230具体可以包括发射端电流转换电路、谐振电路。该发射端电流转换电路与该谐
振电路电连接。其中,发射端电流转换电路可以采用“逆变”原理,将供电电路板210提供的直流电能转换为交流电能,并将该转换后的交流电能传输给谐振电路。进一步,谐振电路则可以将接收到的交流电能的频率调整至预设频率范围。
如图3所示,电能接收组件300包括:接收端控制芯片310、接收端电流调整电路320,以及接收线圈330。其中,如图3所示,接收线圈330与上述发射线圈240相对间隔设置,且接收线圈330与发射线圈240之间可传输电能。具体的,接收线圈330可与接收端电流调整电路320电连接,由于其与发射线圈240相对间隔设置,故其可以感应到发射线圈240所发射的电磁能,进而基于电磁感应原理,将接收到的电磁能转换为交流电能,并将转换后的交流电能传输给接收端电流调整电路320。进一步,接收端电流调整电路320与接收端控制芯片310电连接,其可以在接收端控制芯片310的控制下,对接收到的交流电能进行整流、滤波等处理,以将接收到的交流电能转换为直流电能。进一步,接收端电流调整电路320与天线组件120电连接,其可以将转换后的直流电能传输给天线组件120,以对天线组件120进行供电,保证天线组件120的正常工作。
在基于小型雷达的体积与结构,发明人在实现本发明的过程中发现,发射线圈240与接收线圈330之间的距离与电能传输效率相关,如果发射线圈240与接收线圈330之间距离过小,则发射线圈240与接收线圈330产生互感现象,影响传输效率;如果发射线圈240与接收线圈330之间距离过大,则传输距离较远,影响传输效率,因此,有必要将发射线圈240与接收线圈330之间的距离设计在一个合适的范围值。在较佳的实施例中,可以将发射线圈240与接收线圈330之间的距离优选地控制在1.5mm~5mm这一距离范围内。例如,发射线圈240与接收线圈330之间的距离可以为1.5mm,1.6mm,1.7mm,1.8mm,1.9mm,2.0mm,2.1mm,2.2mm,2.3mm,2.4mm,2.5mm,2.6mm,2.7mm,2.8mm,2.9mm,3.0mm,3.0mm,3.1mm,3.2mm,3.3mm,3.4mm,3.5mm,3.6mm,3.7mm,3.8mm,3.9mm,4.0mm,4.1mm,4.2mm,4.3mm,4.4mm,4.5mm,4.6mm,4.7mm,4.8mm,4.9mm,5.0mm。
进一步,基于上述发射线圈240与接收线圈330之间的距离范围,以及为了使得后续电能接收组件300向天线组件120提供的直流电能可以满足现有技术中天线组件120正常工作时所需要的电流大小,本申请实施例中还提出如下设置:
在基于小型雷达的体积与结构,发明人在实现本发明的过程中发现,发射线圈240的感值与电能传输效率相关,如果发射线圈240的感值过大或过小,则导致发射线圈240与电容器件的耦合度降低,影响传输效率,因此,有必要将发射线圈240的感值设计在一个合适的范围值。在较佳的实施例中,上述发射线圈240的感值可以优选地控制在8.5uH~11uH这一
感值范围内。例如,上述发射线圈240的感值可以为8.5uH,8.6uH,8.7uH,8.8uH,8.9uH,9.0uH,9.1uH,9.2uH,9.3uH,9.4uH,9.5uH,9.6uH,9.7uH,9.8uH,9.9uH,10.0uH,10.1uH,10.2uH,10.3uH,10.4uH,10.5uH,10.6uH,10.7uH,10.8uH,10.9uH,11.0uH。
在基于小型雷达的体积与结构,发明人在实现本发明的过程中发现,接收线圈330的感值与电能传输效率相关,如果接收线圈330的感值过大或过小,则导致接收线圈330与电容器件的耦合度降低,影响传输效率,因此,有必要将接收线圈330的感值设计在一个合适的范围值。在较佳的实施例中,上述接收线圈330的感值可以优选地控制在7.5uH~11uH这一感值范围内。例如,上述接收线圈330的感值可以为7.5uH,7.6uH,7.7uH,7.8uH,7.9uH,8.0uH,8.1uH,8.2uH,8.3uH,8.4uH,8.5uH,8.6uH,8.7uH,8.8uH,8.9uH,9.0uH,9.1uH,9.2uH,9.3uH,9.4uH,9.5uH,9.6uH,9.7uH,9.8uH,9.9uH,10.0uH,10.1uH,10.2uH,10.3uH,10.4uH,10.5uH,10.6uH,10.7uH,10.8uH,10.9uH,11.0uH。
在基于小型雷达的体积与结构,发明人在实现本发明的过程中发现,交流电的频率与电能传输效率相关,如果交流电的频率过大或过小,则导致电能发射组件200或/及电能接收组件300的功耗增大,影响传输效率,因此,有必要将交流电的频率设计在一个合适的范围值。在较佳的实施例中,上述预设频率范围可优选设置为120KHz~150KHz这一频率范围。例如,上述预设频率可以为120KHz,121KHz,122KHz,123KHz,124KHz,125KHz,126KHz,127KHz,128KHz,129KHz,130KHz,131KHz,132KHz,133KHz,134KHz,135KHz,136KHz,137KHz,138KHz,139KHz,140KHz,141KHz,142KHz,143KHz,144KHz,145KHz,146KHz,147KHz,148KHz,149KHz,150KHz。
至此,由上述描述可知,在图1所示例的雷达装置中,通过将电能发射组件固定安装于底座,将电能接收组件与天线组件电连接,并设置为同天线组件一起旋转,进一步基于电磁感应原理,可以实现电能发射组件将接收到的直流电能转换为电磁能,并发射该电磁能,电能接收组件则将接收到的电磁能转换为直流电能,将该直流电能传输给与其电连接的天线组件,也即实现了对天线组件进行无线供电。在此种供电方式下,由于无需设置线缆以连接天线组件与外部电源,也即消除了线缆的限制,从而可以使得电机实现360°全向旋转,继而驱动天线组件实现360°全向旋转,以更好地探测不同方向上的障碍物。
进一步,考虑到天线组件120还需要将检测到的信息传输给地面站,并接收地面站发送的请求指令,而现有技术中,通常采用线缆连接天线组件与地面站信号源,以传输天线组件120检测到的信息与上述地面站发送的请求指令,由此可见,此种通信方式也将导致由于线缆的限制,使得天线组件120无法进行360°全向旋转。基于此,在本申请实施例中还提出
了无线通信。
具体的,图1所示例的雷达装置中还可以包括第一无线通信组件500与第二无线通信组件400(图1中未示出),该第一无线通信组件500与该第二无线通信组件400之间具有无线通信连接,且基于与上述无线供电类似的原理,可以将第一无线通信组件500安装于上述天线支架140,并与天线组件120电连接,将第二无线通信组件400固定安装于底座110。
基于上述结构,该第一无线通信组件500可以用于向该第二无线通信组件400发送天线组件120检测到的信息,并接收该第二无线通信组件400发送的请求指令。
如下,结合附图,对第一无线通信组件500与第二无线通信组件400各自的结构,以及该两者之间进行无线通信的实现原理、实现过程进行详细描述。
首先说明,考虑到小型雷达的大小和结构,在本申请实施例中,可以采用集成式芯片方案将上述图3所示例的电能发射组件200与上述第二无线通信组件400集成于同一电路板上;相应的,也可以采用集成式芯片方案将上述图3所示例的电能接收组件300与上述第一无线通信组件500集成于同一电路板上。
具体的,请参见图4,该图4在上述图3的基础上,着重示例了第一无线通信组件500与第二无线通信组件400的结构。如图4所示,第一无线通信组件500与电能接收组件300集成在接收端电路板上,其可以与电能接收组件300中的接收端电流调整电路320电连接,以由接收端电流调整电路320对其进行供电。该第一无线通信组件500可以包括:第一信号控制芯片510、第一天线模块520。其中,第一信号控制芯片510可以控制第一天线模块520发射与其电连接的天线组件120所检测到的数据信号,以及接收外部信号源发送的数据信号,例如接收地面站发送的请求指令。
如图4所示,第二无线通信组件400与电能发射组件200集成在发射端电路板上,其可以与电能发射组件200中的供电电路板210电连接,以由供电电路板210对其进行供电。该第二无线通信组件400可以包括:第二信号控制芯片410、第二天线模块420。其中,第二信号控制芯片410可以控制第二天线模块420接收外部信号源发送的数据信号,例如接收上述第一天线模块520发射的数据信号,以及发射数据信号,例如发送地面站的请求指令。
为了实现第一天线模块520与第二天线模块420之间进行无线通信,在一实施例中,上述第一天线模块520可以为WIFI无线模块,相应的,第二天线模块420也可以为WIFI无线模块。

另外,从结构形状角度而言,在一实施例中,上述第一天线模块520可以为板状天线,相应的,第二天线模块420也可以为板状天线。
至此,由上述描述可知,在图1所示例的雷达装置中,第二无线通信组件400固定安装于底座,第一无线通信组件500与天线组件电连接,且该两者之间具有无线通信连接。在此种通信方式下,由于无需在天线组件与底座之间布设线缆以传输数据信号,也即消除了线缆的限制,从而可以使得电机实现360°全向旋转,继而驱动天线组件实现360°全向旋转,以更好地探测不同方向上的障碍物。
至此,完成了实施例一的相关描述。
