Description
本发明涉及通信技术领域，特别是涉及一种移动终端充电系统、移动终端及其充电装置。
电力线通信(Power Line Communication，简称为PLC)作为电力系统传输信息的一种基本手段，在电力系统通信和远动控制中得到广泛应用，经历了从分立到集成，从功能单一到微机自动控制，从模拟到数字的发展历程。
目前PLC正在向大容量、高速率方向发展，同时转向采用低压配电网进行载波通信，以便实现家庭用户利用电力线打电话、上网等多种业务。国外如美国、日本、以色列等国家正在开展低压配电网通信的研究和试验。由美国3COM，Intel，Cisco，日本松下等13家公司联合组建使用电力线作为传送媒介的家庭网络推进团体——“Homeplug Powerline Alliance”，已经提出家庭插座(Home Plug)计划，旨在推动以电力线为传输媒介的数字化家庭(Digital Home)。我国也正在进行利用电力线上网的试验研究。可以预见，在将来人们可以使用电力线实现计算机联网及因特网(Internet)接入、小区安全监控、智能自动抄表、家庭智能网络管理等业务，以低压电力线为传输媒介的载波通信技术必将得到更为广泛的关注和研究。

以下结合附图对本发明进行详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
如图1所示，本发明的实施例提供一种移动终端充电系统，包括：
充电装置1，充电装置1一端与电力线3连接，另一端与移动终端2连接，设置为将电力线3上的电力信号传输至移动终端2的直流电源(例如电池，未示出)，以为移动终端2充电，同时使移动终端2与电力线3上的其他终端(未示出)通信；
移动终端2，与充电装置1相连，设置为通过充电装置1充电，同时通过充电装置1与电力线3上的其他终端通信。
本发明实施例提供的移动终端充电系统，移动终端2能够利用充电装置1接通电力线3，与电力线3接通后，移动终端2不仅能够为自身充电，还能够将通信信号传输到电力线3上或者接收电力线3传来的通信信号，从而通过电力线3实现与电力线3上的其他终端的相互通信，为移动终端提供了另一种形式的通信互联，大大扩展了电力线通信的应用范围。
需要说明的是，本实施例中，电力线3除了作为动力电能的载体外，还承担着电力线载波通信的任务，也就是说，在电力线3上传输着两种信号，一种是220V 60Hz的工频交流电，还有一种是频率较高但强度较弱的通信信号，这些通信信号的频率和幅度符合电力线通信的相关标准和协议。
本实施例中，移动终端2与其他设备之间的互联通信除了无线方式完成外，如无线保真(Wireless-Fidelity，简称为WiFi)，蓝牙等，还提供了一种利用有线方式实现彼此互联通信的方式。为了实现这一目标，本发明的实施例对移动终端2及其借以接入电力网络的工具--充电装置分别进行结构上的改进。
如图2所示，在本发明的一个实施例中，移动终端充电系统的充电装置1除了包括整流滤波等电路结构以便将60Hz220V的工频交流电转换成直流电以外，还可包括第一信号耦合部11，第一信号耦合部11一端与电力线3连接，另一端与移动终端2连接，设置为从电力线3上耦合通信信号并将所述通信信号向移动终端2传输，或者设置为将来自移动终端2的通信信号耦合到电力线3。这样，电力线3上的通信信号就能够与电力信号区分开，从而绕开充电
装置1的交流-直流转化电路，而通过另一种方式进入充电装置1并向移动终端2传输。同样道理，移动终端2与其他设备的通信信号也可以不经过天线来向外传输，而是通过充电装置1的信号耦合部11传输到电力线3上，从而通过电力线3与其他设备进行通信。
可选的，该充电装置1可以为任何能够将移动终端2与电力线3相连的电路结构或设备，如目前移动终端比较通用的通用串行总线(Universal Serial Bus，简称为USB)等。第一信号耦合部11就可以设置在USB线的电源插头一侧，以便将电力线3上的通信信号与电力信号区分开后，沿USB线传输到移动终端2的内部。
需要说明的是，虽然在充电装置1与电力线3的连接处，通信信号与电力信号需要彼此分开后分别耦合到充电装置1中，但在随后的信号传输过程中，电力信号与通信信号却都可以沿着同样的线路传向移动终端2。这是因为，通常的充电装置的插头内都包括将高压交流信号转变为低压直流信号的电路模块，如果不将通信信号与电力信号区分开，通信信号就会被淹没在工频信号中，一起被转换成直流电，无法进行通信了。但当电力信号转化成直流信号后，该直流信号就可以与通信信号一起在导线上传输，通信信号不会被淹没或损失掉。需要说明的是，当通信信号在导线上传输时，为了避免通信信号直接对地短路，可以在导线和地之间连接电感器，这样对于直流电信号而言，该导线为地线，对于交流通信信号而言，通信信号又会被电感器阻挡不会与地短路。当然，也可以根据需要将通信信号与电力信号分开传输，本发明的实施例对此不作限制。
如图3所示，移动终端充电系统的移动终端2可包括：
第二信号耦合部21，第二信号耦合部21一端与充电装置1连接，另一端与调制解调部22连接，设置为将来自充电装置1的通信信号耦合到调制解调部22，或者设置为从调制解调部22耦合通信信号并将所述通信信号向充电装置1传输；
调制解调部22，一端与第二信号耦合部21连接，另一端与中央处理器连接，设置为对来自充电装置1的通信信号进行调制解调并向中央处理器传输，或者设置为将来自中央处理器的通信信号进行调制解调并向充电装置1传输。
这样，通过第二信号耦合部21和调制解调部22，移动终端2可以将充电装置1传输来的通信信号传送给移动终端2的中央处理器来处理，从而根据需要向用户进行相应的界面显示，还可以接收用户的操作指令，并转化成相应的通信信号，通过调制解调部22以及第二信号耦合部21向充电装置1传输，从而与电力线3上的其他设备顺利通信。
可选的，当通过电力线3进行通信的信息需要加密进行安全性保护时，调制解调部22还可以根据用户的指令对通信信号进行各种加密，或者对用户进行身份认证，从而保证电力线通信中的各个终端的安全性。
相应的，本发明的实施例还提供一种充电装置1，如图2所示，该充电装置1包括第一信号耦合部11，第一信号耦合部11一端与电力线3连接，另一端与移动终端2连接，设置为从电力线3上耦合通信信号并将所述通信信号向移动终端2传输，或者设置为将来自移动终端2
的通信信号耦合到电力线3。
本发明实施例提供的充电装置1，能够接通电力线3，一方面为移动终端2充电，另一方面还能够将移动终端2发送的通信信号传输到电力线3上或者将电力线3传来的通信信号传输给移动终端，从而使移动终端2能够通过电力线3与电力线3上的其他终端进行相互通信，为移动终端2提供了另一种形式的通信互联，大大扩展了电力线通信的应用范围。
可选的，第一信号耦合部11可包括电容器C1。通过对电容器C1的电容值的合理选取，电容器C1可以使电路达到良好的通高频阻低频、通交流隔直流的效果。例如，当电力线3上同时存在60Hz的工频信号和几千赫兹的通信信号时，为电容器C1选择合适的电容值即可将通信信号耦合到充电装置1中，而将工频信号阻隔在外。
为了能对耦合到充电装置1中的通信信号进行有效的信号处理，可选的，如图4所示，第一信号耦合部11还可包括第一电压变换模块110，第一电压变换模块110可以通过电容器C1分别与电力线3以及移动终端2连接，设置为将从电力线3上耦合的通信信号或者来自移动终端2的通信信号进行电压变换。可选的，第一电压变换模块110可以包括变压器、信号放大电路、耦合线圈等任何能够进行变压转换的电路结构或部件，本发明的实施例对此不做限定。
相应的，本发明的实施例还提供一种移动终端2，如图3所示，包括：
第二信号耦合部21，一端与充电装置1连接，另一端与调制解调部22连接，设置为将来自充电装置1的通信信号耦合到调制解调部22，或者设置为从调制解调部22耦合通信信号并将所述通信信号向充电装置1传输；
调制解调部22，一端与第二信号耦合部21连接，另一端与中央处理器连接，设置为对来自充电装置1的通信信号进行调制解调并向所述中央处理器传输，或者设置为将来自中央处理器的通信信号进行调制解调并向充电装置1传输。
本发明实施例提供的移动终端2，能够利用充电装置1接通电力线3，与电力线3接通后，移动终端2不仅能够为自身充电，还能够将通信信号传输到电力线3上或者接收电力线3传来的通信信号，从而通过电力线3实现与电力线3上的其他终端的相互通信，大大扩展了电力线通信的应用范围。
可选的，第二信号耦合部21可包括电容器C2。通过对电容器C2的电容值的合理选取，电容器C2可以达到良好的通高频阻低频、通交流隔直流的效果。例如，当移动终端2从充电装置1中同时接收直流电力信号和交流通信信号时，第二信号耦合部21可以通过电容器C2将交流通信信号耦合进来，而将直流电力信号隔离开。
可选的，如图5所示，第二信号耦合部21还可包括第二电压变换模块210，第二电压变换模块210可以通过电容器C2分别与充电装置1以及调制解调部22连接，设置为将来自充电装置1的通信信号或者来自调制解调部22的通信信号进行电压变换。可选的，第二电压变换模块210可以包括变压器、信号放大电路、耦合线圈等任何能够进行变压转换的电路结构
或部件，本发明的实施例对此不做限定。
下面通过具体实施例来对本发明提供的移动终端充电系统、移动终端及其充电装置进行详细说明。
如图6所示，在本发明的一个实施例中，有N个手机都插在充电器上充电，用户拿起A手机进行扫描。则在手机屏幕上显示有N-1个手机，并且每个手机的命名也不一样。比如：A1，A2，A3……A(n-1)。当该用户要用A手机与另一个手机进行互联时，可以在手机屏幕上选择要连接的手机名字，对方同意后即可连接成功。用户也可以为自己的手机或者要传输的文件进行加密处理，以提高网络安全。可选的，连接在同一条电力线上的各种移动终端之间还可以组成局域网，并且可以以其中某一个移动终端为热点，使连接到该移动终端的其他用户连接到因特网。
如图7所示，在本发明的另一个实施例中，当移动终端通过充电器插到220V的电力线上时，如果家里电表具有电力线抄表功能，那么可以通过该移动终端与电表进行电力线通信以便查看家里电表的用电情况。
此外，在停电的情况下，连接在同一条电力线上的各个移动终端还可以检测到其他移动终端的存在，并根据目前自身的电量情况，请求其他移动终端给自己的手机供电，或者为其他请求供电的手机等移动终端供电，从而实现了移动终端之间的相互充电。例如，如图8所示，手机A1电量不足，需要充电。手机A3电量充足。那么手机A1可以向手机A3发出充电请求，当手机A3同意给手机A1充电时，则手机A1将被充电。
工业实用性：通过上述描述可知，本发明实施例提供的移动终端充电系统，移动终端2能够利用充电装置1接通电力线3，与电力线3接通后，移动终端2不仅能够为自身充电，还能够将通信信号传输到电力线3上或者接收电力线3传来的通信信号，从而通过电力线3实现与电力线3上的其他终端的相互通信，为移动终端提供了另一种形式的通信互联，大大扩展了电力线通信的应用范围。
尽管为示例目的，已经公开了本发明的可选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
