一种基于总线方式的家庭网关子系统以及数字家庭系统 技术领域
本发明涉及一种基于总线方式的家庭网关子系统以及数字家庭系统, 尤 其是一种基于总线方式, 在外网和内网之间进行信息传递的, 由主机设备和 用户操作设备构建而成的家庭网关子系统; 以及基由家庭网关子系统和家庭 内部无线信号收发器构建而成的数字家庭系统。 背景技术
随着网络技术与信息家电产业的发展, 使得原有单纯的家电设备可以与 网络连接, 从而产生了信息家电, 也叫做网络家电。
家庭中家电设备与互联网连接必须要通过家庭网关, 现有家庭网关装置 有三种形式: 第一种是机顶盒, 主要是实现对电视机的控制。 第二种是计算 机。 第三种是通信网关, 主要负责家庭外部接入和内部联网, 对信息家电设 备的控制能力弱。
现有的信息家电可以单独通过家庭网关与互联网连接, 也可以将多个家 电统一的通过一个家电网关与互联网进行通信。 如果将多个信息家电与家庭 网关连接, 并通过家庭网关进行统一的通信管理, 便构成了数字家庭系统, 现有的家电系统主要是通过局域网的方式, 每个家电设备就是台小电脑, 由 于 " IPv4" 地址有限, 一般设备 IP都是私网地址, 即每个家电设备都会有一 个 IP地址, 当各个信息家电与外部网络之间的 IP通信, 需经过家庭网关的 网给地址转换 ( Network Addres s Trans lat ion; 以下筒称: NAT )处理,这种 处理比较复杂, 而且采用了传输控制 /网际协议 ( Transfer Controln Protocol/ Internet Protocol ; 以下筒称: TCP/ IP )协议栈后, 家电成本较 高, 每个家电设备都需有处理器来处理通信。
因此, 现有的家庭网关及数字家庭系统存在以下缺陷: 1 )现有技术中, 4艮多家电设备采用独立的家庭网关与互联网进行信息交 互的, 例如: 电视机顶盒, 它是针对电视机的专用网关设备, 对其他家电的 控制管理能力较弱。 这种方式不便于家电设备的统一管理。
2 )在现有技术中的数字家庭系统中, 网关设备与外部通信网的通信需经 过家庭网关的 NAT处理, 然后再发送给信息家电。 这种局域网的通信方式对 于家电系统来说并非必要, 加重了家电设备和网关设备的负荷, 并且不利于 信息安全管理, 具体来说:
例如, 该控制指令是用户通过移动终端发出的, 如果信息家电对于移动 终端发来的指令进行较强的安全认证, 则增加了信息家电的计算开销, 相应 的将增加成本。 如果信息家电对于移动终端发来的指令所进行的安全认证不 够强, 这样虽然节省了开销, 但降低了安全性, 对家庭信息的安全构成隐患。
3 )另外, 对于家庭网关本身来说, 用户操作所需的光驱、 通用串行总线 ( Universa l Ser ia l Bus ; 以下筒称: USB )接口等一般都直接设置在家庭网 关的主机设备上, 用户操作不太方便。
某些家庭网关可提供外置式的光驱和 USB接口, 增强了用户操作的方便 性,但这些外置式的光驱和 USB接口必须采用专用的线缆(如 USB线缆、 PCI-E 接口线缆)与主机设备相连接。 另外, 现有家庭网关的键盘和鼠标要么必须 采用信号线缆(如 USB线缆)与主机设备相连接,要么必须采用无线接口(如 蓝牙、 红外线) 。
对于采用信号线缆与主机设备相连接的方式, 若用户需操作设备(如通 过 USB接口、 串口、 并口连接的设备, 例如: 键盘、 鼠标、 光驱、 小液晶显 示屏、 扬声器、 耳机麦克插孔、 仿真电话机(由仿真叉簧、 仿真电话手柄、 仿真电话机键盘组成) ) 与主机设备之间有一定距离, 则用户操作设备与网 关主机设备间的连接线缆不便于部署, 例如: 主机设备置于放电视的墙面一 侧, 而用户需操作设备置于另一侧放沙发墙面, 考虑到美观和操作方便的因 素, 很难进行部署。 在一篇名为 《基于 USB接口的电力线载波通信模块的设计》文章中, 介 绍了应用电力线承载 USB信号的相关技术内容, 文中公开了基于 USB接口的 电力线载波通信模块分两部分, USB信号电路和电力线调制解调器电路; 在 USB信号电路中, 对 USB总线串行信号的接收和解码、 令牌包的解释、 格式 的检查、 传输错误的处理等, 均由接口芯片的硬件实现, 电力线调制解调器 电路的设计宝包括输入滤波器电路、 输出緩存电路、 输出滤波电路以及输出 功率放大电路, 耦合电路的作用在于从电力线引进来和把信号耦合到电力线 上。
对于采用无线接口与主机设备相连接的方式, 对于外置式的光驱和 USB 接口, 与主机模块之间的通信速率要求较高 (10Mbps以上) , 若采用无线局 域网络 ( Wi reles s Loca l Area Network; 以下筒称: WLAN )或蓝牙的方式, 造成数据传输速率和质量的降低。
某些采用无线接口的外置式的光驱和接口装置需配置电池, 其充电次数 达到一定数量之后, 待机时间和通话时间都将明显缩短。 若更换电池, 则增 加用户的使用成本、 增加资源消耗。 发明内容
本发明的第一目的是解决现有技术存在的缺陷, 提供一种基本由主机设 备和用户操作设备构建而成的, 基于数字总线的家庭网关子系统, 实现家庭 内网与家庭外部的通信网络相互隔离, 提高家庭网络的安全性, 并且将家庭 内网中的所有信息家电设备进行统一管理。
本发明的第二目的是解决现有技术存在的缺陷,提供一种数字家庭系统, 其基本由家庭网关子系统和无线收发器构建而成, 实现向家庭内部网络提供 基于数字总线的接口, 使得家庭内部信息家电和可接收数字总线信号的家电 设备作为家庭网关子系统的外部设备,家庭内部网络对外部网络是不可见的。 为实现上述第一目的, 本发明提供了一种家庭网关子系统。 该子系统包 括:
主机设备,用于将外部网络接入家庭内部,以及基于数字总线方式对家庭 内部各信息家电进行控制;
用户操作设备,通过数字总线接口与所述主机设备进行通信,提供各种用 户操作接口和控制单元。
为实现上述第二目的, 本发明提供了一种数字家庭系统。 该数字家庭系 统包括:
家庭网关子系统, 通过 IP接入与外部通信网相连, 用于提供各种控制信 号; 所述家庭网关子系统包括: 主机设备,用于将外部网络接入家庭内部,以 及基于数字总线方式对家庭内部进行控制;用户操作设备,通过数字总线接口 与所述主机设备进行通信,提供各种用户操作接口和控制单元;
多个无线信号收发器, 与所述家庭网关子系统主机设备相连, 用于收发
PLC载波信号和收发无线信号, 并完成 PLC载波信号和无线信号的双向转换。
由以上技术方案可知, 本发明提供的家庭网关子系统以及基于该家庭网 关子系统的数字家庭系统实现了基于数字总线如 USB总线方式对家庭内部各 种家电进行控制, 内部的所有信息家电都是主机模块的计算机外部设备。 因 此, 数字家庭内部网络对外部网络而言是不可见, 外部网络只能看到家庭网 关主机设备本身。 这样, 所有的安全认证功能都集中在主机设备上。 由于主 机设备提供通用的计算资源, 就使得在基本不增加信息家电计算开销的基础 上, 为信息家电提供了高度的安全性能。
电源线及电源插座是家庭内分布最广的线缆系统。 采用本发明所提出的 家庭网关系统, 用户操作设备与主机设备之间可以直接通过电力线通信, 也 可配置无线接口, 在用户操作设备不接电源时, 通过内部电池供电实现无线 通信。 因此, 用户可以更方便地部署及操作本家庭网关系统。 附图说明

在图 1-图 12所示的家庭网关子系统中主机设备在系统中起到核心控制 的作用, 为数字家庭提供通用计算资源和通信网关枢纽功能。 对于家庭外部 网络, 主机设备是数字家庭的网络接入点。 对于家庭内部的所有信息家电, 主机设备是主控计算机, 也即: 家庭内部的所有信息家电都是主机设备基于 数字总线如 USB总线或者 1 394总线或者其他总线方式的计算机外部设备。对 于家庭网关子系统自身, 除了电视机(用作主机设备的显示器)之外, 其他 所有设备, 包括用户操作设备和遥控器, 都是主机设备基于数字总线如 USB 总线的计算机外部设备。 因此, 将家庭内网和家庭外部的通信网络如 IP接入 网相隔离, 所有的家庭内部的信息家电或者可接收无线信号的无线家电设备 对外部网络来说是不可见的, 家庭网关子系统保证了家庭内部的安全性。
本发明提出的家庭网关子系统采用模块化结构, 组成子系统的各个设备 可分布式放置, 由一台主机设备、 一台电视机、 一台用户操作设备、 一个或 多个遥控器组成。
如图 1 3 所示, 为本发明数字家庭系统实施例一的结构示意图, 数字 家庭系统 1 00由家庭网关子系统 20以及多个无线信号收发器 11构成, 家 庭网关子系统 20 ,与通过 IP接入网 1 0接入外部通信网络用于提供各种控制 信号; 所述家庭网关子系统 20包括: 主机设备 1, 设置有存储介质, 如硬盘 2 , 用于将外部网络接入家庭内部,以及基于数字总线方式如 USB总线方式对 家庭内部进行控制;用户操作设备 4,通过数字总线方式与所述主机设备进行 通信,提供各种用户操作接口和控制单元; 该数字总线方式如 USB信号承载 于 PLC或者无线接口上; 多个无线信号收发器 1 1 , 与所述家庭网关子系统主 机设备 1相连, 用于收发 PLC载波信号和收发无线信号, 并完成 PLC载波信 号和无线信号的双向转换。 图 12所示的家庭网关子系统, 是采用了 PLC进行 信号传送, 这种家庭网关子系统只要通过电源接口接到电源插座就行。 当电 源插座出现异常情况, 如出现松动, 没有接通电源时, 该家庭网关子系统可 以使用自己的备用电池。 即在主机设备 1 上设置有第一电池及电源模块 3 , 在用户操作设备 4设置有第二电池及电源模块 5 , 通过这两个备用电源模块, 可以使得家庭网关子系统一直处于接通状态, 避免出现异常问题。
如图 14所示数字家庭系统实施例二,在数字家庭系统 100 , 多个可接收 无线信号的家电设备 12 , 通过无线信号接口 1006如 USB接口与所述无线信 号收发器 11相连; 如图 15所示数字家庭系统实施例三, 还可包括: 信息家 电 1 3 , 用于通过供电线路与主机设备进行数字总线信号通信; 也可以包括多 个可接收无线信号的家电设备 12直接通过数据总线接口与主机设备相连,此 时数据总线接口是主机设备中的微型基站单元提供的接口形式, 可以是无线 USB收发装置; 如图 16所示数字家庭系统实施例四, 还可包括上网计算机 14 , 通过电脑上网接口 1007与所述主机设备 1相连。 实施例四是在实施例 3 的基础上增加了上网计算机 14 , 该上网计算机也可在实施例一和实施例二的 基础上增加, 其连接关系与实施四中的相同, 在附图中, 省略结构示意图。 如图 17 所示数字家庭系统实施例五, 还包括: 远程控制器 15 , 通过移动 IP1 008接入 IP接入网, 用于通过 IP接入网和主机设备远程控制各种家电设 备。
可接收无线信号的家电设备具有无线信号处理单元, 用来接收无线控制 信号, 在这种可接收无线信号的家电设备接收到无线控制信号后, 家电设备 核心处理单元根据该无线控制信号进行对家电设备的控制。 如无线空调、 冰 箱、 微波炉、 热水器等。
此处, 信息家电是相对于可接收无线信号的家电说的, 即不采用无线方 式通信的家电, 如直接连 CABLE的电视机, 接电力线的电灯开关等。
若上述可接收无线信号的家电没有配置无线功能, 也可采用电力线信号 传输。
在该数字家庭系统中, 家庭网关子系统的结构图, 如图 1-图 12所示, 在此不再赘述。 利用该数字家庭系统用户通过家庭网关子系统中的遥控器, 通过无线接口将控制信息发送给主机设备, 主机设备将该无线控制信号转换 成电力线信号, 找到信息家电对其进行控制。 数字家庭系统中, 也有各种可 接收无线信号的家电设备, 这些家电设备通过安装在房间、 车库或者庭院中 的无线信号收发器, 将无线信号发送给这些无线信号收发器, 或者通过无线 信号收发器接收从主机设备中无线信号处理单元发出的无线信号, 对这些家 电设备进行控制,控制信号可以直接是遥控器发送给主机设备的主板处理器, 该主板处理器对发送来的各种控制信号进行分析判断, 然后将控制信号通过 无线信号处理单元处理后发送给家电设备进行控制。 用户也可以通过移动通 信装置如手机对数字家庭系统中的家电进行控制, 通过主处理板以及无线信 号处理单元、 第一电力线调制解调单元和电力线滤波器的作用, 将该控制信 号发送给家庭内部的家电。 在该数字家庭系统中, 主机设备接入网络服务器 时, 网络服务器对其移动通信装置识别模块进行身份识别, 移动通信装置识 别模块中存放有身份识别信息, 验证该主机设备是否有权接入。
同时, 在数字家庭系统中, 电视机可以作为公知电视机使用, 直接播放 有线电视节目, 或者电视机作为家庭网关子系统的一个显示设备, 通过用户 操作设备提供的键盘、 鼠标、 光驱、 音箱等, 而电视机则可以作为主机设备 显示器, 这样便实现了一个分离设置的电脑, 便于用户使用。 例如, 可以将 用户操作设备设置在沙发的附近,在该用户操作设备上用户控制键盘和鼠标, 而沙发对面放置电视机作为主机设备的显示装置, 用户可以很方便的在沙发 上通过键盘和鼠标对网关系统进行控制, 而不必考虑布线上的问题, 如果采 用传统的方式, 键盘、 鼠标和显示器的连接线不易部署, 会受到距离及家庭 中其他设备的限制。
在该数字家庭系统中, 由于由电视信号控制及选频单元、 电视信号处 理单元、 和主处理板所提供的电视信号处理功能共同组成, 具有类似机顶 盒功能, 因此,通过家庭网关子系统主机设备就能够进行电视节目的收看。
在该数字家庭系统中, 用户使用计算机上网, 可以将计算机接到家庭 网关子系统的电脑上网接口登录网络。
在本发明数字家庭系统的组网去除了以太网的结构, 采用最筒单便利的 布网方式: 以家庭最常见的电力线为主要承载线路, 数字总线信号如 USB信 号直接适配到电力线上; 各房间和车库、 庭院等范围内都设有无线信号收发 器, 近距离内设备可直接采用无线信号通信; 通过电力线与无线信号收发器 的连接, 延长了无线无线信号的通信距离。
在本发明中, 数字总线信号可考虑采用 USB信号或者 1 394信号或者其他 的总线方式。
最后应说明的是: 以上实施例仅用以说明本发明的技术方案, 而非对 其限制; 尽管参照前述实施例对本发明进行了详细的说明, 本领域的普通 技术人员应当理解: 其依然可以对前述各实施例所记载的技术方案进行修 改, 或者对其中部分技术特征进行等同替换; 而这些修改或者替换, 并不 使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
