Description

一种带能量传输的无线通信系统 技术领域
本发明属于无线通信技术领域，尤其涉及一种带能量传输的无线通信系统。
背景技术
无线能量传输作为一种能量传输手段，可以在非接触的状态下，不借助线缆等媒介实现电能传输。近年来无线能量传输在无线充电等领域等获得了成功应用，而在无线能量和信息同时传输等结合领域也有了一定探索。目前无线能量和信息同时传输，有采用磁场共振和微波辐射传输两种方法，分别对应于窄带和宽带通信系统。
非辐射性磁耦合谐振作为新型无线供电技术，通过使两个相同频率的谐振物体产生很强的相互耦合，而对周围非谐振频率的接受端只有较弱的耦合。磁耦合谐振系统包括发射谐振线圈、次级接受谐振线圈和负载。无线供电应用场合通常需要无线通信，按照能量流与信息流的实现方式，主要分为单流模式和双流模式。其中双流模式采用能量流与信息流分开实现，如采用蓝牙等无线装置实现信息流。这种方式成本相对较高，电路复杂。而单流模式利用同一套装置实现能量流与信息流的复用。
目前对无线能量和信息传输的研究主要集中在天线和射频单元的物理设计，以提高设备间点对点传输时无线能量和信息同时传输的效率。但是在多个设备进行分布式组网时，如何基于时分方式控制各个设备在无线能量和信息传输之间的转换仍未有相关研究。而传统的基于时分方式的分布式通信协议CSMA协议显然也不能直接用于采用无线能量和信息传输技术的新型设备的分布式组网。因此需要对此类场景的设备组网协议进行设计，通过将无线能量和信息传输引入能量受限的分布式无线网络(如无线传感器网络)，以延长这些网络中设备的电池使用时间。

通信系统工作方式：数据信号传输系统FPGA将数据数据进行加扰，令数据不包含较低频带的频谱分量，比如数据率50Mbps时，等效物理频率25MHz，而通过对数据加扰，令其不包含5MHz以下频率分量，而电源传输及其干扰，便可分布于LF-5MHz之间。与之后的无线电能传输系统的工作频率错开，通过LVDS电平信号输出，在外部通过将LVDS电平信号转换为TTL信号并进行功率增强之后，进入电磁转换驱动器，驱动磁环线圈对外发射高频无线数字信号；接收端通过磁环线圈感应到发射线圈发射的磁场信号后将磁场变化转换为电信号变化，再将转换出来的电信号进行高通滤波、放大、整形还原为原始的LVDS信号馈入接收端的FPGA进行信号还原。由于结合了电能传输系统，因此在信号与能量同时传输时必将引入干扰甚至对原始信号造成破坏。因此，数据传输与能量传输的频率应尽量错开较大的频率范围。必要时引入滤波器滤除能量传输系统带来的负面干扰。保证数据信号传输的稳定性和可靠性。
能量(电力)系统工作方式：低频能量传输通过使用低频率振荡电磁信号将电能辐射到空气中，并接收。具体流程为：通过FPGA生成低频率(方波频谱主要能量频带 在2MHz以下)的PWM控制信号(带死区控制)，通过MOSFET驱动电路驱动功率MOSFET，进行功率放大并驱动电磁转换线圈磁环向外辐射电能。接收端通过带磁环线圈耦合到发射端辐射的电磁信号之后，将磁能转换为电能。再通过整流稳压电路输出恒定的电压电流，然后提供给其他电路使用。由于能量传输系统与信号传输系统的磁耦合一体化设计，数据信号和能量信号在同一磁链路中的不同频带范围内进行传输，在考虑效率以及干扰的情况下尽量提高能量传输系统的工作频率，以使系统效能最高。
在控制模块中FPGA同时发出控制信号，其中一路输出给LVDS信号转换模块进行将LVDA信号转换成TTL信号后输出给电磁转换模块，电磁转换模块接收TTL信号，并将电信号转换成磁信号输出给磁环耦合模块将磁信通过耦合方式无线转换后输出给磁电转换模块，磁电转换模块将接收到的磁信号还原成TTL信号后输出给TTL信号转换模块，TTL信号转换模块将接收的TTL信号转换成LVDS信号后输出给接收模块完成信号传输；另一路输出信号进入MOS驱动模块，通过MOS驱动模块驱动MOS功率放大模块的MOS管进行功率放大并驱动电磁转换线圈磁环向外辐射电能，接收端通过带磁环线圈耦合到发射端辐射的电磁信号之后，将磁能转换为电能。再通过整流稳压模块输出恒定的电压电流，然后提供给其他电路使用。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
