Description

尤其用于户内区域的通信系统 In particular, a communication system for indoor areas

技术领域 FIELD

本发明涉及尤其用于户内区域的通信系统和用于该系统的适配器设备。 In particular, the present invention relates to a communication system for indoor area and an adapter device of the system.

现有技术通信技术的结网在不断地进步。 Prior art communications technology continues to progress in the netting. 一方面,用户想尽可能随处都能被电话达到,另一方面应该还能从任意的位置利用简单的装置传输数据。 On the one hand, they want as much as possible everywhere can be reached telephone, on the other hand should be able to use simple means to transfer data from any location. 为了满足该需求,已经研制了一些手持无线电话,它们不仅能实现语音传输,而且还能执行数据传输。 To meet this demand, has developed a number of hand-held wireless phone, they can not only voice transmission, but also to perform data transmission. 为后一目的而给它们装配了一种红外接口,以便譬如能够与膝上型计算机建立通信连接。 For the latter purpose they are fitted to an infrared interface, for example in order to establish a communication connection with the laptop computer.

然而,借助手持无线电话传输数据只在特殊的情况下具有意义。 However, with hand-held wireless telephone transmission data has meaning only in exceptional circumstances. 操作仍然被认为是复杂的。 Operation is still considered to be complex. 另外从统计的观点来看,大多数数据依然是经固定安装的电缆传输的。 In addition, from a statistical point of view, most of the data is still transmitted via cable fixed installed. 譬如在办公大楼内敷设计算机电缆,以便连接数据处理设备。 For example, computer cables laid in the office, in order to connect the data processing device.

安装新的电缆是与大量的成本联系在一起的。 Install the new cable is associated with significant cost together. 在此也已经建议通过如下方式来降低这类成本,即采用每个建筑物内的已有供电网导线来传输信号(提示语:PLC=电力线通信)。 Here also it has been suggested to reduce costs through such a way that using the existing power supply network wires in each building to transmit signals (prompt: PLC = Power Line Communication). 但目前在实际中这是有问题的,即很少装配有设备用于这类传输。 But in practice this is a problem, i.e. fitted with a device for such rarely transmission. 在可实现这种信号传输之前,必须装入相应的耦合器。 Before such signal transmission can be achieved, it must be loaded with the appropriate coupler. 这-特别在实施阶段-决不是比敷设计算机电缆更便宜的方案。 This is - especially in the implementation phase - is not cheaper than laying computer cables scheme.

发明叙述本发明的任务在于创造一种用于户内区域的通信系统,它允许成本适宜地进行结网。 Invention described object of the invention is to create a communication system for indoor area, which allows the cost of the netting is suitably performed.

该任务的解决方案由权利要求1的特征给出。 The object is achieved by the features of claim 1 is given. 根据本发明如此地构造所述的通信系统,使得在两个终端之间建立一种点对点连接,该点对点连接在至少一个终端和适配器设备之间包括有一个短距离无线链路,以及在所述的适配器设备和第二终端之间具有一个经供电电网输送的PLC线路。 The communication system of the present invention thus configured, so that between the two terminals to establish a peer to peer connection, point to point connection between the terminal and the at least one adapter device comprises a short-range wireless link, and in the PLC circuit having a power supply delivered by the adapter between the device and the second terminal. (短距离无线链路被理解为无线连接,其作用距离基本上不超过户内区域,也即譬如不超过房间、楼层或建筑物的大小。)本发明的该系统在安装方面非常灵活和便宜。 (Short-range wireless link is understood to be a wireless connection, which is substantially effective distance of no more than indoor area, i.e. such not to exceed the size of the room, a floor or a building.) The system of the present invention is very flexible and cheap installation . 所述的适配器设备可以连接到供电电网的任意插座上,也即在恰好需要它的地方。 The adapter can be connected to the power supply network at any outlet, i.e. at exactly where it is needed. 用于短距离无线链路的器件或部件在目前可以大批量和极便宜地生产。 Devices or components for short-range radio link is currently available in large quantities and very cheap to produce. 通过所述的点对点连接,还可以取消集中控制设备或连接控制器(“基站”)。 Through the connection point of the centralized control device can also be canceled or the connection controller ( "base station"). 可以通过在时间上分级来同时保持多个通信连接(在许多情形下这对于用户是呈现出并行的通信)。 While maintaining the connection may be passed over a plurality of communication to the time hierarchy (which, in many cases the user is presented for parallel communication). 另外,通过有意选择的短作用距离,可以譬如把并不处于相同房间的无线区域自然地分离开来。 Further the wireless area by intentionally selected short operating range, for example, can not in the same room is naturally separated.

优选地,所述无线链路的作用距离基本上只局限于建筑物的一个房间的供给。 Preferably, the radio link distance is substantially limited to the role of feeding a room of a building. 该作用距离可以小于20米,譬如约为10米。 The effect of distance may be less than 20 meters, for example about 10 meters. 在该意义上譬如可以使用所谓的“蓝牙”接口。 For example you can use so-called "Bluetooth" interface that sense. 但也可以采取具有较大作用距离的接口,譬如IEEE 802.11(“无线LAN”)或“Hiperlan”。 It may take the role of an interface with a larger distance, such as IEEE 802.11 ( "Wireless LAN") or "Hiperlan". 利用它们绝对可以覆盖多个相邻的房间。 They absolutely can cover multiple use of adjoining rooms. (“蓝牙”和“Hiperlan”是已知和标准化的接口。)由所述的PLC线路连接两个不同的房间。 ( "Bluetooth" and "Hiperlan," are known and standardized interface.) Two different rooms line connection by said PLC. 也就是说,两个终端通常位于建筑物的不同房间内,而且通过PLC系统经供电线路进行连接。 That is, the two terminals are located in different rooms of a building generally, and are connected via the power supply line by the PLC system. 如果无线链路的作用距离只限于一个房间,则本发明的系统便呈现如下特征,即在建筑物的每个(需开发的)房间内把本发明的适配器连接到所述的供电电网上,以便使位于该房间内的设备能与布置在其它地方的设备产生通信技术连接。 If the action is limited to a wireless link from a room, the system will be presented according to the present invention is characterized in that in each (development required) the room of a building according to the present invention, the adapter is connected to the power supply network, in the apparatus so as to produce in the room is connected to the ICT device is arranged elsewhere. 所述的第二终端无须利用无线技术与所述的PLC干线相连。 Said second terminal using wireless technology without the PLC connected to the mains. 也可以使用有线的电耦合。 You can also use a wired electrically coupled.

显然,两个设备不必装设在相同的建筑物内。 Obviously, the two devices do not have to be installed in the same building. 所述的PLC系统譬如也可以向户外区域开放,以便优选地经外部供电电网(或在其中所实现的户外PLC系统)与世界上任何地方的任何设备进行通信。 The PLC system may be open to such outdoor areas, preferably to communicate with any device anywhere in the world via an external power supply (or outside the PLC system implemented therein). 位于户内区域和户外区域之间的连接可以通过所谓的桥来实现,以及供电电网和任意其它网络(譬如光纤WAN)之间的过渡可以通过布置于变电站区域的主站来实现。 Located in the connection between the indoor and the outdoor area regions may be realized by a so-called bridge, and the transition between the power supply and any other networks (such as the optical fiber WAN) may be achieved by arranging the substation to the main station area. 从户内区域到户外区域的过渡(网关)也可以被实施为两个不同传输媒质之间的过渡(譬如从PLC过渡到电话线或过渡到光LAN)。 The transition region from the indoor to the outdoor area (gateway) may also be implemented as a transition between two different transmission media (for example, the transition from the PLC to a telephone line or the transition to the optical LAN).

本发明的通信系统尤其适用于家庭自动化。 Communication system of the present invention is particularly suitable for home automation. 譬如可以用简单的方式对炊具设备进行结网。 For example cooking device can netting in a simple manner. 譬如装配有蓝牙接口的微波炉可以通过适配器设备被连接到PLC干线上,并且譬如通过控制设备或计算机程序进行接通和关断。 For example, equipped with a Bluetooth interface may be connected microwave oven via the mains adapter device to the PLC, and such are turned on and off by the control device or computer program. 在PLC系统的合适装配下,所述的炊具设备也可以通过无线电进行操作。 PLC under suitable assembly system, the cooking apparatus may also be operated via radio. 譬如来讲述一种具有通往PLC系统的数据接口的电话设备。 For example to tell the telephone device having a data interface leading to the PLC system. 用户譬如可以利用其手持无线电话在家里进行呼叫,并利用特殊的代码触发所述的电话设备接通所述的干线(通过PLC线路和蓝牙接口)。 For example, users can use their portable radiotelephone call in the home, using a special code to trigger the trunk of the telephone apparatus is turned on (via line PLC and a Bluetooth interface).

在工业运营方面,可以设想把无线接收机放置在不同的建筑物内,由该无线接收机在为专用数据传输所提供的频带内接收长距离的无线信号,并且将其耦合到供电电网中。 In terms of industrial operations, it is contemplated that the wireless receiver is disposed in a different building, a long distance in the received frequency band dedicated data transmission provided by the radio receiver of the radio signal and couples it to the power grid. 在机房内,由插入在插座内的适配器设备经短距离无线链路把控制指令传输给机器控制器。 In the engine room, by the insertion within the receptacle adapter device via a short-range radio link to transmit a control command to the machine controller.

本发明的原理还可以很广泛地应用于自动化或遥控。 The principles of the present invention may also be very widely used in automation or remote control. 因此不仅涉及计算机或其类似物的结网,而且还涉及在控制设备和执行设备之间提供通信媒质。 Thus not only relates to a computer or the like netting, but also to provide a communication medium between the control device and the execution apparatus.

用于本发明通信系统的作为适配器设备的装置可以尽可能小而简单地实施。 A communication system of the present invention as an apparatus adapter device may be implemented as a small and simple. 它的特征在于一种用于短距离无线链路的发射机/接收机。 It is characterized by short-range wireless link A transmitter / receiver used. 利用常规的电网插头来实现耦合到供电电网上。 To implement coupled to the power supply network with conventional grid plug. 该装置可尽可能便宜地制造,并且在光学上不引入注意(也即在美学上是不受干扰的)。 The device may be manufactured as cheaply as possible, and unobtrusive optically (i.e. aesthetically undisturbed). 从投资来讲,该装置对用户而言可以象过去的延长电缆那样被作为另一电话台。 From the terms of investment, the apparatus for the user as in the past can be used as extension cables as another telephone station. 因此,当用户觉得有意义和认为有必要时,可以简单地买到所述的适配器设备。 Thus, when users find meaningful if necessary and think, you can simply buy the adapter device. 不需要利用特殊清单进行早期的计划和费事的安装(这在扩展电话网时是必要的)。 It does not require the use of a special list for early planning and installation of trouble (which is necessary in the expansion of the telephone network).

根据一种特别优选的实施方案,所述的适配器设备具有紧凑的外壳形状,且带有成形的电网插头。 According to a particularly preferred embodiment, the adapter apparatus has a compact shape of the housing, and with a plug-shaped grid. 它可以直接插入供电电网的接线插孔中(譬如壁式插座),并且在哪儿都无须“安装”。 It can be directly inserted into the connector receptacle in the power supply network (such as a wall socket), and are not required "mounted" Where. 在建筑物内譬如设立蓝牙接口电路、PLC接口电路和交换微控制器。 Set up in a building such as a Bluetooth interface circuit, PLC interface circuit and switching the microcontroller.

当所述的适配器设备具有至少一个用于任意设备的电网插头的接线插孔时,便是比较有利的。 When said terminal plug adapter device having at least one power plug for any device, is more favorable. (适配器设备的插头和接线插孔在此具有相同的标准。)于是避免了“丧失”房间内所安装的用于其它用途的接线插孔。 (Plug adapter devices and connection sockets herein have the same standard.) Thus avoiding connection sockets "loss" installed in the room for other purposes. 在日常清扫家用设备时,家庭主妇可以把吸尘器插入适配器设备的接线插孔,并无须到处搜寻其它的壁式插座。 When routine cleaning of household equipment, housewives terminal plug can be inserted into the vacuum cleaner adapter device, and need not search around for further wall outlet.

如果所述的适配器设备具有多个自由的接线插孔,则它同时还具有经常所需的多插头功能。 If the connection sockets of the adapter device having a plurality of free, it has also often required for multi-function plug. 譬如可以毫无问题地把本发明的适配器功能集成到已知结构类型的插座板中。 Without problems such as the function of the present invention, the adapter is integrated into the structure of a known type of outlet plate. 这种插座板譬如可以通过短电缆被连接到所述的壁式插座上,并在长形的建筑物内具有多个串联布置的接线插孔。 This may for example be a socket board through a short cable connected to the wall outlet, and having a plurality of connection sockets arranged in series within the elongate structure. 它通常位于不起干扰作用的地板上(譬如位于写字台之后)。 It is usually located on the floor can not afford to interference (for example, after the desk is located).

在上述具有至少一个用于第三设备的接线插孔的实施方案中,在电网插头的相应触头和所述的接线插孔之间至少装设了两根被构造用于导电的导线。 In the embodiment having at least one terminal plug for the third device, the respective contacts between the power plug and the terminal plug mounted at least two leads being configured for conduction. 根据一种优选实施方案,所述的导线具有高频扼流圈,由它们明显地衰减大于1MHz范围的信号(譬如衰减至少10dB)。 According to a preferred embodiment, the wire having a high-frequency choke, by their significantly attenuate signals greater than 1MHz range (for example, attenuated by at least 10dB). 因此,通信信号不可能不经衰减地经所述的连接插孔进入所连接的设备内。 Thus, the communication signal is not possible without attenuation through the connection jack into the connected devices. 对于连接在电网上的其它设备,所述PLC系统(譬如在1MHz~30MHz的范围内工作)的干扰可能性可以被最小化。 For other devices connected to the power grid, the possibility of interference of the PLC system (for example, work in the range of 1MHz ~ 30MHz) may be minimized. (在相反的方向上,显然也可以利用该方法把来自所述第三设备的、对供电电网和PLC系统的干扰保持在某个程度。)应当理解,当需要在1MHz以下进行通信时,可以相应地匹配所述的扼流圈。 (In the opposite direction, this method may be apparent from the third device to the interference of the power grid and the PLC system is maintained to some extent.) It should be appreciated that, when it is desired to communicate 1MHz or less, accordingly, the matching choke coil.

从下面的详述和整个权利要求书中可以得出本发明的其它优选实施方案和特征组合。 From the book the following detailed description and throughout the claims of the present invention can be derived to other preferred embodiments and combinations of features.

附图简述为解释实施例而采用的附图示出了:图1为一种户内通信系统的简图;图2为一种被实施成多插头形式的适配器设备的实施例;图3为一种被实施成中间插头形式的适配器设备的实施例;图4为一种适配器设备的内部构造的简图。 Brief Description of the embodiments is explained using the drawings show: FIG. 1 is a schematic view of an in indoor communication system; FIG. 2 is embodied as a plug in the form of embodiment of a multiple adapter apparatus; FIG. 3 Example embodiments are implemented as a plug in the form of an intermediate adapter apparatus; FIG. 4 is a schematic view of an internal configuration of an adapter device.

原则上,附图中的相同部件是用相同的参考符号表示的。 In principle, identical parts in the figures are denoted by the same reference symbols.

用于实施本发明的途径图1简略地示出了户内区域的通信系统。 Ways for carrying out the invention FIG 1 schematically shows a communication system of the indoor area. 建筑物1具有常规的屋内供电电网2,该供电电网通常被接在外部供电电网3上。 Building a house 2 having a conventional power supply, the power supply is typically connected to the external power supply 3. 在建筑物1中,位于不同房间A~C内的设备(譬如台式计算机21、打印机23、膝上型计算机22、家用设备20和/或手持无线电话19)需要用通信技术连接起来。 1 in a building, in the apparatus in different rooms A ~ C (for example, a desktop computer 21, a printer 23, a laptop computer 22, domestic appliances 20 and / or the portable radio telephone 19) to be connected together by communication technology.

根据本发明,一方面设立一种用于在各房间之间传输信号的PLC系统,另一方面还设立一个短距离无线接口以把信号从设备传输到房间内的PLC系统。 According to the present invention, in an aspect of the establishment of a method for transmitting signals between the PLC system of the room, on the other hand also created a short-range wireless interface to a signal from the device to the PLC system in the room.

主设备4和两个从属设备5、6通过电网插座7、8、9被连接到供电电网2上,并且能够在该通路上相互交换频率范围譬如为1~40MHz的信号。 Two master devices and slave devices 4 via the power grid 5, 6 is connected to the receptacle 7,8,9 power supply network 2, and can exchange signals such as the frequency range 1 ~ 40MHz of each other on the path. 在本实施例中,所述的主设备4和从属设备6被构造为本发明的适配器设备的形式。 In the present embodiment, the master device and the slave device 4 is configured to 6 of the present invention in the form of an adapter device. 也就是说它们具有蓝牙接口12或13,以用于与相同房间内的其它设备进行短距离的无线通信。 That is they have a Bluetooth interface 12 or 13 to other devices within the same room for the short-distance wireless communication. 相反,从属设备5只具有用于连接台式计算机21的有线数据端子18(譬如RS232,IEC488,以太网)。 Instead, the slave device 5 has a data connection for a wired desktop computer 21, terminal 18 (such as RS232, IEC488, Ethernet).

另外在供电电网2上还以常规的方式经电网插座10、11连接了其它设备。 Also in the power grid 2 is also a conventional manner via a power socket 10, 11 is connected to other devices.

如果现在譬如需要把存放在膝上型计算机22上的文件传输到台式计算机21,那么膝上型计算机22的相应数据便可以经其蓝牙接口16被发送到从属设备6,再经供电电网2发送到从属设备5,最后从该从属设备5发送到所述的台式计算机21。 For example if we need to be stored on the laptop computer 22 is a desktop computer 21 to a file transfer, then the corresponding data can laptop computer 22 via the Bluetooth interface 16 which is transmitted to the slave device 6, and then transmitted via the power supply grid 2 5 to the slave device, the slave device transmitted last from 5 to 21 according to a desktop computer.

存储在台式计算机21上的文件可以经数据端子18被传输给从属设备5,再经供电电网2(PLC线路)传输给从属设备6,然后从那儿经蓝牙接口13被传输给同样装配有蓝牙接口17的打印机23(经无线链路46)。 File is stored on a desktop computer 21 may be connected with the data terminal 18 is transmitted to the slave device 5, (PLC line) transmission and then the power supply network 2 to the slave device 6, and then transmitted from there via a Bluetooth interface 13 to likewise equipped with a Bluetooth interface 17 printer 23 (via radio link 46). 利用该方式可以把所述的打印机23用作网络打印机。 With this embodiment of the printer 23 can be used as a network printer.

显然也可以设想在打印机23的内部装配一种耦合器(其在功能上相当于从属设备),并且不经蓝牙接口17而利用所述的耦合器来直接接收数据。 Obviously also conceivable printer inside COUPLED assembly 23 (which functionally corresponds to the slave device), and does not utilize the coupler to receive data directly via the Bluetooth interface 17.

譬如可使用所述的手持无线电话19来发送台式计算机21的电子邮件。 For example, using the hand-held wireless telephone 19 to send e-mail desktop computer 21. 电子邮件又从台式计算机21被传送给从属设备5,然后从该从属设备传送到供电电网2。 21 and from a desktop computer e-mail is transmitted to the slave device 5, and then transmitted from the slave device 2 to the power grid. 由主设备4经其蓝牙接口12把电子邮件发送给同样装配有蓝牙接口14的手持无线电话,也即利用无线链路45。 4 by the master device via its Bluetooth interface 12 equipped with the same email to Bluetooth interface 14 of the portable radio telephone, i.e. using a wireless link 45.

优选地,譬如可以由所述的台式计算机21来控制家用设备20。 Preferably, such a home device 20 may be controlled by the desktop computer 21. 该家用设备虽然经电网插座10与供电电网2相连,但这种连接并不用于传输数据。 While the household appliance via the socket 2 is connected to the power grid 10 and the power grid, but the connections are not used for data transmission. 具体说是在(未示出的)控制部分内集成了蓝牙接口15。 Is in particular (not illustrated) integrated Bluetooth interface control section 15.

需要注意的是,这总是涉及点对点的连接。 It should be noted that this always involves a point to point connection. 主设备4并不接管集中交换功能(譬如屋内电话网的PBX)。 4 is not centralized master device takes over the switching function (such as house PBX telephone network). 具体地说,它只被用来根据请求给从属设备提供供电电网2上的信道。 Specifically, it is only used to provide the channel 2 on the supply network to a slave device upon request.

在图1中,主设备4譬如可以被构造成通往外部供电电网3的桥。 In Figure 1, for example, the master device 4 may be configured to bridge to an external power supply 3. 于是,该主设备可以经所述的外部供电电网3建立通向外部世界的通信技术连接。 Then, the master device may be via an external power supply of claim 3 to the outside world to establish a communication connection technology. (在户外区域通常以不同于户内区域的频率进行工作,所以必须利用一个桥作为“转换”。)但通往外部世界的通信连接也可以利用电话线(XDSL)、电视电缆(CATV)或甚至通过长距离的无线电来建立。 (Typically at a frequency region is different from the indoor outdoor area in the work, it is necessary to use a bridge as "conversion.") But the communication is connected to the outside world can also use the telephone line (XDSL), cable television (CATV) or even established by long-distance radio. 因此,本发明的户内结网决不只局限于其本身,而是可以提供各种所需的连接可能性。 Accordingly, the present invention is the indoor netting itself not limited, but may be required to provide various connection possibilities.

图2示出了适配设备的第一实施方案。 FIG 2 shows a first embodiment of the adapter device. 它包括一个插座板24,该插座板通过电缆25并利用插头26插入到所安装的壁式插座或其类似物中。 It includes a socket plate 24, the socket plate 25 through the cable 26 and fill the plug is inserted into a wall outlet, or the like is installed. 插座板24可以按已知的方式具有多个电流接线插孔27.1~27.4,并在需要时具有一个电流开关28(以便以常规的方式关断插座板上的电流)。 Socket 24 may have a plurality of plate current connections known manner jack 27.1 ~ 27.4, and 28 having a current switch (current in a conventional manner to the off socket board) when required. 在所述插座板24的背向电缆25的一端,在外壳内集成了一个适配器29。 In the end facing away from the receptacle plate 25 of the cable 24, within the housing incorporates an adapter 29. 该适配器具有一个蓝牙接口和一个PLC接口,并由此实现已借助图1所阐述的、与合适构造的设备所进行的通信。 The adapter has a Bluetooth interface and a PLC interface, and thus communication has been achieved by, with a suitable configuration of the apparatus illustrated in Figure 1 is performed. (该适配器29的细节在图4中示出。)图3示出了一种非常有利的实施方案。 (The adapter 29 is shown in detail in FIG. 4.) Figure 3 shows a very advantageous embodiment. 在譬如为长方体的外壳30的一侧构造了一个标准的电网插头31,而在其另一(相对的)侧构造了一个电流接线插孔32。 In the example, a standard grid configuration 31 of the plug side housing 30 is a rectangular parallelepiped, and at the other (opposite) side structure of a current connection sockets 32. (该电流接线插孔可以与电网插头31具有相同的标准,但这不是必须的。)在外壳30内,除电流接线插孔32之外譬如还在侧面装设了适配器33。 (The current connection sockets 31 may have the same standard power plug, but not necessarily.) Within the housing 30, in addition to the current connection sockets 32 such as adapter 33 also mounted side.

这种实施方案的特征是在于其结构的紧凑性。 Feature of this embodiment lies in its structural compactness. 插头、穿孔和接口电子装置构成了一种可靠而又坚固的整体。 Plugs, perforations and interface electronics constitutes a reliable and robust overall. 所述的适配器设备可以插入到壁式插座(它被装在一个可舒适地够得着的地方)中,而不会“占用”所述的壁式插座。 The adapter device may be inserted into a wall outlet (which is mounted in a comfortable place to reach it) and without "occupy" the wall outlet.

图4简略地示出了适配器设备34的电路图。 FIG 4 schematically shows a circuit diagram of an adapter device 34. 电网插头35譬如具有三个触头(P=相线,N=零线,PE=保护线),它们在本例中被示为针。 Power plug 35 having three such contacts (P = phase, N = neutral, PE = protection line), which are shown in this embodiment is a needle. 所述的三个触头通过导线39.1~39.3被连接到接线插孔36的相应触头上。 The three contacts are connected to 39.1 ~ 39.3 the corresponding contacts 36 of the terminal plug through the wire. 电网插头35的相线P和零线N利用导线39.1、39.2被直接导往数据端子37.1、37.2。 Plug-phase power P and the neutral line N of 35 with a wire guide directly 39.1,39.2 37.1, 37.2 to the data terminal. 在所述的导线39.1、39.2上还连接了接线插孔36的相线P和零线N。 39.1,39.2 on the wire insertion hole 36 is also connected to a wiring phase line P and the neutral line N. 但通过扼流圈38.1、38.2来引入高频隔离,使得经数据端子37.1、37.2馈入的PLC信号不会不衰减地进入与该接线插孔36相连的设备中。 However, by introducing a high frequency choke to isolate 38.1,38.2, such that the data of the PLC signal terminals 37.1, 37.2 are not fed into the apparatus without attenuation connected to the terminal plug 36. 所述的扼流圈38.1、38.2可以用电感元件构成,它在所使用的信号频率范围内产生可以察觉的衰减(譬如>3dB)。 38.1,38.2 may sense the electrical choke configuration elements, it can produce noticeable attenuation (for example,> 3dB) signal within the frequency range used.

用于保护的触头PE是直接相连的,而没有在中间接入电感。 PE for protecting the contacts are directly connected, but not in the middle with an inductor.

同时用于给适配器设备34的电子器件供电的数据端子37.1、37.2被连接到PLC接口40上,由该PLC接口建立通往PLC通信系统的接口。 While the electronic device for supplying data to the adapter device 34 connected to the terminals 37.1, 37.2 are on the PLC interface 40 by the PLC to the PLC interface to access the communication system interface. 接于其后的微控制器41在PLC接口40和蓝牙接口42之间实现数据交换。 After the microcontroller 41 which it is connected for data exchange between the PLC interface 40 and the Bluetooth interface 42. 由集成在该适配器设备34内的天线43发送和接收短距离的无线信号。 Transmitted by the integrated device 34 in the adapter 43 and the receiving antenna of short range wireless signals.

经天线43接收的无线信号被转换成PLC信号,并被传送给供电电网的两根导线、即相线和零线。 Received via the antenna 43 the radio signal is converted into a PLC signal, and transmitted to the two wires of the power grid, i.e., the phase and neutral. 在相反方向上,数据端子37.1、37.2上的PLC信号被耦合输出,并作为蓝牙无线信号用天线43发射出去。 In the opposite direction, PLC signal on the data terminal is coupled to the output 37.1, 37.2, and Bluetooth as a radio signal emitted by antenna 43.

图4所示的电路方案对图2和3所示的结构方案是同样适用的。 FIG circuit scheme shown in FIG. 2 and the structure shown in Scheme 3 is equally applicable. 在插座板24的情况下,在导线39.1、39.2、39.3上简单地并联了多个电流接线插孔27.1~27.4。 In the case where the socket plate 24 on conductor 39.1,39.2,39.3 simply connected in parallel a plurality of current connection sockets 27.1 and 27.4. 扼流圈在此并不是必需的。 The choke is not required. 它可以装设在其它位置,或干脆被取消。 It can be installed in other locations, or simply be canceled. 只有当在接线插孔上接有灵敏的设备(譬如计算机,立体设备,测试设备)或干扰设备(吸尘器等)时,该扼流圈才是非常重要的。 Only when there is contact sensitive devices (such as computers, stereo equipment, test equipment) or interference devices (vacuum cleaners) on the terminal insertion hole when the choke is very important.

尽管使用蓝牙接口是一种非常优选的实施方案,但采用长作用距离的无线接口(譬如IEEE 802.11或Hiperlan)也是决定可以的,而且在某些情况下甚至是有意义的。 Although Bluetooth interface is a very preferred embodiment, but with a long effective distance wireless interface (such as IEEE 802.11 or Hiperlan,) is determined possible, and in some cases even significant.

本发明并不局限于所示的实施例。 It is not limited to the illustrated embodiment of the present invention. 特别从结构的角度来看可以有各种各样的变型。 In particular there may be a variety of variations from a structural standpoint. 例如,电网插头31和电流接线插孔32可以不对准共同的轴。 For example, the grid 31 and the power connection jack plug 32 may not be aligned to a common axis. 它们也可以不装设在外壳30的相对侧。 They may not be installed on the opposite side of the housing 30.

从图2可以看出,本发明也可以在延长的电缆内实施。 As can be seen from Figure 2, may be implemented in the extension cable of the present invention. 于是在插座板24的位置处采取单个的接线插孔。 Then take a single terminal plug socket board at a position of 24.

图4所示的适配器设备也可以被实施为两部分。 FIG adapter device shown in FIG. 4 may also be implemented in two parts. 在一部分内包含电网插头35、接线插孔36和扼流圈38.1、38.2。 Grid comprising a portion of the plug 35, the wiring hole 36 and choke 38.1,38.2. 在另一部分内装设所述的电子器件(接口电路和微控制器)。 Mounted in another portion of the electronic device (interface circuitry and microcontrollers).

另外,本发明并不局限于两相的供电电网。 Further, the present invention is not limited to the two-phase power supply. 一种优选的应用领域尤其可以是三相电网,其中设有多个相线。 A preferred field of application may in particular be three-phase network, wherein a plurality of phase lines. 在某种情况下,一个房间内(尤其当其较大时)也可以使用两个适配器。 In some cases, a room (especially when it is greater) may also be used two adapters. 如果无线链路的作用距离不局限于一个单独的房间,则显然不必(在全部覆盖所述建筑物的情况下)在每个房间内都设置适配器设备。 If the action is not limited to a wireless link from a separate room, then obviously not necessary (in the case of covering the whole of the building) are set adapter device in each room.

总之可以得出,本发明揭示了一种成本合适的方法,以用于在户内区域或超过该区域进行通信。 In conclusion can be drawn, the present invention discloses a cost suitable method, for indoors or beyond the area of ​​the communication area. 它利用较低的费用就可以把地点固定的或移动的、具有短作用距离无线接口的设备相互连接起来。 It uses low cost to the location can be fixed or mobile device having a short distance wireless interface to effect a connection to each other.
