具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细说明：
本发明的保护范围不受限于以下的实施例及附图。本发明的权利范围，应以权利要求为基础，进行解释。
如图1所示，家庭网络系统1通过因特网络2联接到LnCP服务器3。另外客户设备4通过因特网络2联接到LnCP服务器3。即，家庭网络系统1把LnCP服务器3及/或客户设备4联接成可以互相传递信息。
家庭网络系统1的外部网络包括因特网络2，外部网络根据客户设备4的种类还可具备其它设备。即，以该因特网络2为例，客户设备4为计算机时具备Web服务器(Websever)(未图示)，客户设备4为网络电话时具备无线应用协议服务器(Wap sever)(未图示)。
LnCP服务器3通过特定的注册及注销程序，分别联接到家庭网络系统1及客户设备4，从客户设备4接收监视及控制命令等，再通过因特网络2用特定形式的信息传送到家庭网络系统1。另外，LnCP服务器3从家庭网络系统1接收并储存特定形式的信息或把它传送到客户设备4。另外，LnCP服务器3把自身储存或生成的信息传送到家庭网络系统1。即，家庭网络系统1联接在LnCP服务器3，可下载LnCP服务器3所提供的服务内容。
家庭网络系统1包括网关10，网络管理器20～23，LnCP路由器30，31，LnCP适配器(adapter)35，36及多个电器设备40～49。网关10具有联接因特网的功能。网络管理器20～23履行对电器设备40～49的环境设定及管理功能。LnCP路由器30、31负责传输媒体之间的联接。LnCP适配器35，36可以使网络管理器22及电器设备46联接到传输媒体。
家庭网络系统1内的网络由各电器设备40～49共用的传输媒体相互联接组成。该传输媒体可利用RS-485或低功率的RF等数据链路层(datalink)非规格化的传输媒体(non-standardized transmission medium)，或可以利用电力线或IEEE 802.11等规格化的传输媒体(standardizedtransmission medium)。
家庭网络系统1内的网络是与因特网络2相互分离的网络。即，家庭网络系统1内的网络构成由有线或无线传输媒体联接的独立网络。独立网络是指处于物理上的联接状态但理论上分离的网络。
家庭网络系统1包括主控(Master)设备，从属(Slave)设备。主控设备可以控制电器设备40～49或监视其工作状态。从属设备可以回应主控设备的请求及通知自身状态的变化信息。该主控设备包括网络管理器20～23，从属设备包括电器设备40～49。该网络管理器20～23包括所要控制的电器设备40～49的信息及控制码，按程序化的方式进行控制作业，或接收从LnCP服务器及/或客户设备4输入的信息后，进行控制作业。另外，如图1所示，联接有多个网络管理器20～23时，为了进行与其它网络管理器20～23之间的交换信息，也为了信息的同步化以及进行控制，这些网络管理器20～23即可以是主控设备又可以是从属设备。即应该是一种，从物理意义上只是一个设备，但理论上是同时具有主控及从属功能的设备(即兼容设备)。
另外，这些网络管理器20～23及电器设备40～49可以直接联接到网络(如图1所示的电力线网络、RS-485网络、RF网络)上。另外，还可以通过LnCP路由器30、31及/或LnCP网络适配器35，36联接。
另外，电器设备40～49及/或LnCP路由器30、31及/或LnCP网络适配器35，36注册在网络管理器20～23上，并根据产品信息，接收唯一的逻辑地址(例如0x00，0x01等)。这个逻辑地址与产品码(例如空调为‘0x02’，洗衣机为’0x01’)结合后，作为节点地址(Node Address)使用。
图2为本发明的生活网络控制协议(LnCP)框图。家庭网络系统1通过图2中的生活网络控制协议(LnCP)可以使网络管理器20～23、LnCP路由器30，31、LnCP网络适配器35，36及电器设备40～49之间互相传送信息。网络管理器20～23LnCP路由器30，31、LnCP网络适配器35，36及电器设备40～49通过这种LnCP实行网络通信。
如图2所示，LnCP包括应用软件50、应用层60、网络层70、数据链路层80、物理层90及媒介变量管理层100。应用软件50发挥网络管理器20～23、LnCP路由器30，31、LnCP网络适配器35，36、及电器设备40～49的固有功能。并提供与应用层60联接的功能，以便在网络上进行远程操作及监视。应用层60向使用者提供服务，并具有把使用者提供的信息或命令组成信息后传达到下位层的功能。网络层70可以把网络管理器20～23、LnCP路由器30，31、LnCP网络适配器35，36及电器设备40～49之间联接为可靠的网络。数据链路层80提供联接控制功能，用于联接共用传输媒体。物理层90提供网络管理器20～23、LnCP路由器30，31、LnCP网络适配器35，36及电器设备40～49之间的物理接口及要传送的比特(byte)的规则。媒介变量管理层100管理设定各层中使用的节点的媒介变量(nodeparameter)。
详细的说，应用软件50还包括网络管理附属层51。网络管理附属层51具有管理节点媒介变量，及管理联接在网络上的网络管理器20～23、LnCP路由器30，31、LnCP网络适配器35，36及电器设备40～49的功能。即，该网络管理附属层51具有一种功能，可以通过媒介变量管理层100，设定媒介变量数值或利用媒介变量对媒介变量进行管理。适用于LnCP的设备为主控设备时，该网络管理附属层51还具有履行构成网络或管理网络的功能。
另外，网络层70还包括家庭码控制附属层71。网络联接有网络管理器20～23、LnCP路由器30，31、LnCP网络适配器35，36及电器设备40～49。当利用电力线或IEEE 802.11、无线等非独立形传输媒体(例如LnCP包括电力线通信(PLC)网络协议91/或无线(wireless)网络协议92时)构成网络时，为了在理论上划分各网络，家庭码控制附属层71发挥设定家庭码及管理家庭码的功能。该家庭码控制附属层71通过像RS-485等独立形传输媒体，从物理意义上分离个别网络时，不包括在LnCP中。该家庭码以4字节(byte)组成，设定为随机(random)值或使用者设定值。
图3a及图3b为图2的层间的接口的框图。
图3a所示为物理层90联接到非独立形传输媒体时的层间的接口示意图。图3b所示的是物理层90联接到独立形传输媒体时的层间的接口示意图。
家庭网络系统1把各层需要的标题(header)及结尾(trailer)信息加到从上位层接收的网络协议信息单位(Protocol Data Unit：PDU)中，在传达到下位层。
如图所示，APDU(Application layer PDU)是应用层60和网络层70之间传送的数据值(data)。NPDU(Network Layer PDU)是网络层70与数据链路层80或家庭码附属层71之间传送的数据值。HCNPDU(Home CodeControl Sublayer PDU)是网络层70(确切的说是家庭码附属层71)与数据链路层80或家庭码附属层71之间传送的数据值。数据链路层80与物理层90之间按数据值(data)，数据帧(frame)单位形成接口。
图4a至4f为图3a及3b的接口的详细框图。
图4a所示为在应用层60中的APDU结构。
AL(APDU Length)数字组为表示APDU的长度(AL到数据帧组的长度)的数字组，最小值为4最大值为77。
AHL(APDU Header Length)数字组是表示APDU标题(header)的长度(AL到ALO的长度)，的数字组，没有扩展时为3字节，可以扩展到7字节。LnCP网络协议中为了数据帧组的密码化，为了变更应用协议等APDU标题(header)可以扩展到7字节。
ALO(Application Layer Option)数字组是用于扩展信息块(sheet)的数字组，例如该数字组被设定为“0”后，装有其它值时忽略信息处理。
数据帧组为处理使用者的控制信息或事件(event)信息的数字组，其结构随着ALO所含值的变化发生变化。

DA(Destination Address)及SA(Source Address)的数字组为要传送的数据包的收信方及送信方的节点地址，各由16比特构成。这里最上位1比特为显示群地址的标记(flag)，接下来的7比特为产品的种类(产品码)，下位8比特包括分得的逻辑地址。具有多个同一种类的网络管理器20～23或电器设备40～49时，下位8比特用于划分各网络管理器20～23或电器设备40～49。
PL(Packet Length)数字组为显示要传送的NPDU总长的数字组，其最小值为12字节，最大值为100字节。
SP(Service Priority)数字组为给予传送信息传送优先位的数字组，由3比特构成。各传送信息的优先顺位如表2。
从属客户设备应答主控客户设备的请求时，随从主控客户设备接收到的请求信息的优先顺位。
表2
  优先顺位   值   适用(Application Layer)
  高(High)   0   -传送紧急信息时
中(Middle) 1   -传送普通数据包时-传送对应网络(Online State)在线及非在线状态(Offline State)变化的事件信息时
  标准(Normal) 2   -传送通知构成网络的信息时-传送普通事件信息时
  低(Low)   3   -传送根据下载或上传的厂家的值时
NHL(NPDU Header Length)数字组是用于扩展NPDU标题(header)(SLP中的NLC数字组)使用的数字组，没扩展时是9字节，最大可扩展到16字节。
PV(Protocol Version)数字组是显示所采用的网络协议版本的1字节的数字组，由上位4比特及下位4比特构成。上位4比特为版本(version)数字组，下位4比特为服务器版本(sub-version)数字组。版本(version)及服务器版本(sub-version)分别以16进制标法显示版本。
NPT(Network layer Packet Type)数字组是在网络层中划分数据包种类的4比特数字组。LnCP包括请求数据包(Request Packet)，应答数据包(Response Packet)，通知数据包(Notification Packet)。主控客户设备的NPL数字组应设定为请求数据包或通知数据包，从属设备的NPL数字组应设定为应答数据包或通知数据包。数据包种类的NPT值如下表3所示。
表3
  值   说明
  0   请求数据包
  1~3   不使用

  13~15   与家庭码控制附属层联接的接口用预约值
TC(Transmission Counter)数字组是网络层发生通信故障，不能成功发送请求数据包或应答数据包时，为了提高传送请求数据包或应答数据包的成功率，再传送或反复传送的2比特数字组。收信方可以利用TC数字组的数值，检测出重复信息。随NPT值的TC数字组值的范围同下表4。
表4
  数据包种类   值(范围)
  请求数据包   1~3
  应答数据包   1

PN(Packet Number)数字组由2比特构成。在从属设备中为了检测出重复数据包PN(Packet Number)数字组与TC一起被使用。在主控客户设备中为了处理多个的通信循环被使用。随NPT值的PN数字组的范围如下表5所示。

APDU数字组是应用层60与网络层70之间传送的应用层的网络协议数据值(data)的单位。APDU最小值为0字节，最大值为88字节。
CRC(Cyclic Redundancy Check)数字组是为了检测出已接收数据包(SLP到APDU数字组)的错误的16比特数字组。
ELP(End of LnCP Packet)数字组是显示数据包未端的数字组，其值为0x03。如果接收与数据包长度数字组中的与长度相应的数据值(data)，也不能检测出ELP数字组，则示为数据包错误。
图4d为家庭码控制附属层71中的HCNPDU结构图。
如图所示，NPDU的上位部分还包含HC(Home Code)数字组。
该家庭码的数值由4字节构成。该家庭码在数据包可传播的线路的距离内具有唯一的值。
图4e所示为数据链路层中的数据帧的结构。
LnCP的数据链路层的数据帧的标题(header)及结尾(trailer)根据传输媒体形成不同的结构。数据链路层80使用非规格化的传输媒体时，数据帧的标题(header)及结尾应具有Null数字组(Null Field)。如使用规格化的传输媒体，则随网络协议的规定。NPDU数字组是从上位网络层70传送的数据值的单位。HCNPDU是物理层90为电力线或IEEE 802.11等非独立形传输媒体时使用的数据值单位，是在NPDU前端追加4字节家庭码的数据值单位。层80不划分NPDU及HCNPDU的处理。
图4f为物理层90中的数据帧结构。
LnCP的物理层90具有把物理信号传送到传输媒体的功能。作为LnCP网络协议的物理层90，可以使用与RS-485或低功率RF等同的非规格化数据链路层80的传输媒体。还可以使用如电力线或IEEE 802.11等同的规格化传输媒体。适用LnCP网络的家庭网络系统1中，为了网络管理器20～23及电器设备40～49与RS-485或LnCP路由器30，31，及LnCP适配器35，36联接，利用了UART(Universal Asynchronous Receiver and Transmitter)数据帧结构及RS-232的信号标准(level)。各设备之间利用网线(serialbus)联接时，UART在通信线路控制比特信号流。如图4f所示，在LnCP中，把上位层送来的数据包，变换成10比特大小的UART数据帧单位后，通过传输媒体传送。UART数据帧由1比特的起始位(Start Bit)、8比特的数据值(data)及1比特的停止位(Stop Bit)构成。UART数据帧不使用效验位(Parity Bit)。UART数据帧从起始位传达，最后传达停止位。适用LnCP的家庭网络系统1利用UART时，不使用追加的数据帧标题(frame header)及帧结尾(frame trailer)。
图5a到图5b为本发明的家庭网络系统的地址系统示意图。
图5a中展示本发明家庭网络系统1使用的地址数字组结构。如图所示，产品码具有唯一的值用于识别产品基本功能。该数字组是在产品出厂时被设定的值，是不可改变的物理地址。同样的产品具有同样的固定地址。设备码是一种逻辑地址，用于分辨具有同一产品码的各设备。群地址是按一定的基准设定的对应于一个以上设备的逻辑地址。
图5b为图5a的地址数字组的详细结构图。如图所示，固定地址数字组的MSB被使用为标记(flag)，“0”时意味着设备码，“1”时意味着群码。通过不同地设置整个地址数字组中的MSB值，可以辨认设备码和群码。另外，各辅助数字组内的所有位全部被设定为1时，意味着集团地址。比如，冰箱的产品码为0x01时，0x01FF表示各冰箱的群地址，而0x81XX(这里X表示任意值)表示具有同一群码的所有冰箱的集团地址。
各从属设备每当连接在家庭网络系统1上时，被主控设备自动设定设备码。这里，群码虽然同样可以被主控设备自动设定，但很多情况下因技术上的原因使用者直接对他进行设定。
例如，通过0x0200(空调1)及0x0201(空调2)的相同的节点地址被电器设备40～49及/或LnCP路由器30、31及/或LnCP网络适配器35，36识别。另外，还可以使用按特定的基准(同种产品，产品的设置位置，使用者等)设置的群地址，使用群地址时可以一次性识别一个以上的电器设备40～49及/或LnCP路由器30、31及/或LnCP网络适配器35，36。在这个群地址中，显性群地址把地址选择值(下述为标记flag)设定为“1”时该显性群地址为指定多个的客户设备的集团(cluster)地址。默示群地址把逻辑地址及/或产品码的所有比特(byte)值添加为“1”，进而可以指定多个客户设备。这里，特别要指出的是把明示群地址通常称为集团码。
比如，产品码为0bXXX XXXX，逻辑地址为0bYYYY YYYY，群码为0bZZZZZZZZ，则设备被辨认成8个种类的地址。
(1)所有设备的地址指定是由0b1111 1111 1111 1111或0b0111 11111111 1111(0xFFFF或0x7FFF)组成；
(2)产品码的地址指定由0b1XXX XXXX 1111 1111或0b0XXX XXXX 11111111组成；
(3)群码的地址指定由0b111 1111 ZZZZ ZZZZ组成；
(4)逻辑地址的地址指定由0b0111 1111 YYYY YYYY组成；
(5)产品码和逻辑地址的地址指定由0b0XXX XXXX YYYY YYYY组成；
(6)产品码和群码的地址指定由0b1XXX XXXX ZZZZ ZZZZ组成。
图5c为产品别产品码和地址范围的实施例。这里，地址范围中，0xXX00意味着个产品的初始逻辑地址。如上所述，0xXXFF意味着各产品的群地址，0xXXFE意味着限制逻辑地址(下面将会展示)，其他0xXX01～0xXXFD成为可以分配到主控设备和从属设备的节点地址。
由产品地址和初始逻辑地址组成的节点地址，在产品出厂时，被分别储存在主控设备和从属设备的特定存储装置中。
图6为网络管理器和电器设备的概略示意图。
如图6所示，网络管理器20～23(下面称为主控设备)和电器设备40～49(下面成为从属设备)由用于网络连接的接口装置210、一定的存储装置220、以及控制装置230组成。控制装置通过控制接口装置210和存储装置220，设定对新设备(新电器设备或新网络管理器)的唯一节点地址。
更详细的说，主控设备的存储装置220储存与其他主控设备和从属设备的产品信息以及产品别地址有关的信息。包括连接在网络上的所有产品信息(产品信息和已设定的或未设定的节点地址信息等)的文件，叫做家庭网络文档(HomNet profile)。家庭网络文档储存在存储装置220中，被控制装置230读取或更新后被注册。
从属设备的存储装置220至少储存自己的产品码和初始逻辑地址。该存储装置220还将储存临时逻辑地址和主控设备设定的逻辑地址等。
主控设备还可以具有显示装置(图略)，显示装置包括输入装置(图略)和接口装置。输入装置用于使用者输入某种信号。接口装置根据家庭网络文档，把家电网络系统的所有或一部分电器设备40～49以及/或网络管理器20～23，按图标形式显示给使用者。主控设备还可以具有包括使用者接口的显示装置(图略)，使用者接口可以表示当前和过去的动作状态。
实际上，由主控设备或从属设备的控制装置230进行一些特定作业。但是为了叙述上的方便，下面记载成由主控设备或从属设备进行一些特定作业。
图7为本发明的家庭网络系统设定与新设备相应的编码时的流程图。
更详细的说，阶段S61中，主控设备向使用者表示使用者接口，并在该使用者接口上显示“编码设定按钮”，以便使用者设定群码，主控设备通过输入装置接收使用者对“编码设定按钮”菜单的输入内容。通过过程，进行使用者设定、选择编码的阶段。主控设备为了让使用者能够设定编码，进行如下阶段。
阶段S62中，主控设备通过使用者接口，向电器设备40～49以及、或网络管理器20～23的信息，用图标进行表示。这里，信息至少包括电器设备40～49以及、或网络管理器20～23的当前动作状态，也可以表示过去动作状态。
阶段S63中，使用者利用输入装置选择电器设备40～49以及、或网络管理器20～23中的一个以上。该选择可以按电器设备40～49以及/或网络管理器20～23的设置位置、或使用频度、或使用时间为基准进行。
阶段S64中，使用者设定阶段S63所选设备的编码(群码)。这里，使用者用10进制数进行选择，而主控设备把10进制数改成16进制数，进行储存。而后给使用者显示的群码，可以转换成10进制数进行表示。这里，阶段S63和S64可以按掉过来的顺序进行。即，先进行一定群码的选择后，再进行与之对应的设备的选择。
阶段S65中，主控设备，接收群码后，更新家庭网络文档，以便让已储存的家庭网络文档包括所选设备的节点地址。
阶段S66中，主控设备向选择的设备传送包括该群码的地址变更请求信息。这里，各设备接收地址变更请求信息后，在节点地址中的群码数字组中储存接收的群码，进行设定。
主控设备进行阶段S65或S66后，为了向家庭网络系统1内的其他主控设备(即，网络管理器20～23)通知该选择的设备群码的设定(或变更)，传送包括该群码的地址设定通知信息。从而可以实现整体家庭网络系统内的各主控设备之间的信息同步化。
图8为家庭网络文档的各设备信息实施例。
如图所示，家庭网络系统1包括主控设备(网络管理器)、冰箱、空调1～4、以及微波炉。
各设备连接在家庭网络系统1上，如果可以通信，即可通过主控设备设定节点地址(产品码+逻辑地址(设备码))。接下来，如上所述，被使用者设定群码。如图所示，使用者根据设备设置位置任意设定群码。主控设备和空调1是“0x01”(居室)，冰箱和微波炉是“0x02”(厨房)，空调2是“0x03”(房1)，空调3是“0x04”(房2)，空调4是“0x05”(房3)。
如图5b的说明中所展示的那样，这样设定的群码被应用于唯一的以及/或集团的识别各设备时。
