Description
Technical Field
The invention relates to the field of networking data transmission, in particular to an information transmission device, an information transmission network and a method thereof.
Background
With the rise of the internet of things, more and more devices are connected to the internet. In the prior art, in a home environment, there are a large number of devices of different manufacturers or transmission types (such as Wifi, Zigbee, or PLC). In general, interconnection and interworking between devices of different transmission types cannot be realized.
In order to access a plurality of devices to a home network, a Wifi network, a PLC network, or a Zigbee network is generally established in a home environment, for example, in a typical Wifi network, various Wifi devices such as mobile phones are all accessed to a router to form a home lan. In the local area network, each device or the device and the router realize transmission in a Wifi mode. However, such a single network typically only enables networking of devices of the same transmission type. Therefore, when a large number of devices with different transmission types exist in a family, multiple sets of devices are generally purchased to build multiple networks to meet the network access requirements of the devices, and because the networks are relatively independent, free interaction or communication is difficult to carry out between the devices with different transmission types, namely between different networks, so that the realization of many intelligent home scenes is limited, the intelligent devices cannot play the roles to the maximum, the user experience is difficult to effectively improve, and the development of the intelligent home is influenced. In addition, for the same networking (taking Wifi network as an example), if the home space is large, for example, there are upper and lower two floors, and there are three rooms on each floor, each room has Wifi devices, because of the limitation of signal shielding such as distance or wall penetration, two devices far apart (for example, the two devices are located in different rooms or located on upper and lower floors) are either poor in communication effect or require extremely high cost to achieve a certain communication effect.
There is therefore a need for an efficient and versatile way of information transfer.

In some examples, the predetermined conditions described above may include: pre-configuring and selecting the information transmission device as a control and management node of other information transmission devices; or autonomously selecting the information transmission apparatus from a plurality of information transmission apparatuses including the information transmission apparatus according to a predetermined rule as a control and management node of the other information transmission apparatuses in the plurality of information transmission apparatuses. It is noted that the above are only some examples of predetermined situations for the coordination management unit 130 to implement its functionality. Those skilled in the art may adopt other conceivable methods to make a certain information transmission apparatus a control and management node of a plurality of information transmission apparatuses including it, and the present invention is not limited thereto.

In this case, the coordination management unit 130 may perform management of the other information transmission apparatuses and their respective communication subnets formed according to the information received by the information transceiving unit 140.
In some examples, the information transfer device may further include a transceiver unit (not shown) for communicating with its subnet. However, in other examples, the transceiving unit may also be implemented using the information transceiving unit 140. For example, when the information transmission apparatus communicates with the smart device and other information transmission apparatuses managed by the information transmission apparatus by wireless means, the information transmission apparatus can communicate with the smart device and other information transmission apparatuses using the same (or different) wireless transmitting and receiving unit.

In the communication network, at least one information transmission apparatus is an information transmission apparatus for controlling and managing each information transmission apparatus in the communication network. The other information transmission apparatuses in the communication network may not have a function of controlling and managing the respective information transmission apparatuses in the communication network (for example, not having the coordination management unit 130 shown in fig. 1), or may have such a function but not be activated.
Fig. 2 shows an information transmission method performed by an information transmission apparatus included in a communication network constituted by a plurality of information transmission apparatuses according to an embodiment of the present invention. As shown in fig. 2, the method includes a step 210 of receiving, from another information transmission apparatus of the plurality of information transmission apparatuses, information transmitted by a terminal device managed by the another information transmission apparatus; step 220, determining the information transmission device to which the information destination belongs and the communication protocol used by the information transmission device according to the locally stored information related to the plurality of information transmission devices and the plurality of communication subnets respectively formed by the plurality of information transmission devices; step 230, converting the information into a format according to a communication protocol used by the information transmission device to which the information destination belongs; and a step 240 of forwarding the format-converted information to the information destination information transmission apparatus.

In some examples, before the above-described method is performed, an information transmission apparatus to perform the above-described method may be determined as a control and management node of other information transmission apparatuses from among the plurality of information transmission apparatuses.
In some examples, the determination may be made by one of: pre-configuring and selecting an information transmission apparatus to perform the above method as a control and management node of other information transmission apparatuses; or autonomously selecting an information transmission apparatus to execute the above-described method from a plurality of information transmission apparatuses including the information transmission apparatus to execute the above-described method according to a predetermined rule as a control and management node of the other information transmission apparatuses in the plurality of information transmission apparatuses. As described above, a person skilled in the art may adopt other conceivable methods to make a certain information transmission apparatus a control and management node of a plurality of information transmission apparatuses including the same, and the present invention is not limited thereto.
The communication network may be a home network, and the plurality of communication subnets may be one or more of a ZigBee network, a WiFi network, and a power line communication network. Of course, the communication subnets described above may also be communication networks using any communication protocol currently or developed in the future.
Fig. 3 shows a method for constructing the above-described communication network according to an embodiment of the present invention. As shown in fig. 3, the method includes: step 310, including a plurality of information transmission devices in a communication network, so that the plurality of information transmission devices respectively control one or more intelligent devices according to corresponding communication protocols thereof to respectively form a plurality of communication subnets; and a step 320 of connecting the plurality of information transfer devices, configuring one of the plurality of information transfer devices as a control and management node for managing the other of the plurality of information transfer devices, wherein the non-control and management nodes in the communication network communicate with the control and management node in a direct or indirect manner.
The technical solution of the present invention is briefly described above with reference to fig. 1 to 3. The technical solution of the present invention will be described in more detail with reference to fig. 4 to 9. Note that, in the following description, an example in which a home Smart Point (SP) network is used as the communication network described above and an example in which a Smart Point is used as the information transmission apparatus described above will be described. It should be appreciated, however, that the communication network described above may also take other names as long as it is a communication network made up of a plurality of Smart Devices (SD) of the same or different types.
FIG. 4 shows a more detailed schematic of an application environment according to an embodiment of the present invention. As shown in fig. 4, each smart point can access at least one type of device, the number of each type of device can be multiple, and communication between the smart point and the smart point can be realized. The mobile terminal can communicate with the intelligent point in a home environment (under a local area network) or through a cloud (when going out), and then communication or control with certain home intelligent equipment under the intelligent point is achieved. In addition, an intelligent point can be installed in each room in the home environment, and the intelligent points in different rooms or different floors can be preferably communicated in a PLC mode (namely the first choice of connection between the intelligent points is PLC, WiFi is selected under the condition that the PLC is not communicated, and Zigbee is selected again), so that the existing home power line is fully utilized, and the communication effect is prevented from being influenced by the adoption of a Wifi or Zigbee mode. In a single room, the intelligent point and the intelligent equipment which is connected with the intelligent point can adopt a corresponding communication transmission mode according to the type of the equipment. In addition, as shown in the figure, in the intelligent point network system, the intelligent point (intelligent point a for short) can be connected with the internet, other intelligent points and corresponding devices can be interconnected with the outside through the intelligent point a, the intelligent point a is also responsible for interacting with the cloud, and other intelligent points and corresponding devices can not be connected with the cloud. The intelligent point A is used as a medium to interact with the cloud and manage the connected intelligent points and the corresponding equipment.
In fig. 4, a communication subnet is formed by using ZigBee smart devices and WiFi smart devices as examples of smart devices and smart points corresponding thereto. However, other types of intelligent devices, such as Power Line Communication (PLC) intelligent devices or other intelligent devices known in the art, may also be used in the present invention.
In particular, FIG. 5 depicts the manner in which a smart point network is networked in different network environments.
As shown in fig. 5a, in a WiFi network, there may be one intelligent point functioning as a router and the other intelligent points functioning as bridges; whether the intelligent point is a router or a bridge may be determined primarily by software presets; in general, the intelligent points (typically super intelligent points) of the home network should be routers, while the other intelligent points should be bridges. End devices (including mobile phones, smart home devices, etc.) may access the network through a router or a bridge.
As shown in fig. 5b, in a Zigbee network, since at least one coordinator (necessary for the Zigbee network) is required, one intelligent point functions as a coordinator and the other functions as a router. One intelligent point, whether it functions as a coordinator or a router, may be preset at the time of its firmware formation.
As shown in fig. 5c, in the PLC network, PLC devices having the same domain and key constitute one network. Wherein, at least one master control is needed, and the others are controlled; which is the master control can depend on the power-on working speed of the PLC modules in the intelligent points, and if the PLC module of one intelligent point in one network is already the master control, the PLC modules of other intelligent points can automatically become controlled. In this respect, the role of the respective module can be forcibly positioned at the software level by the SNMP protocol. For example, one of the PLC modules may be forced to be the master, and then all other modules including the modules that have been the master before being automatically powered up may also become controlled.
In a smart point network, there may be one or more smart points. One of the one or more intelligent points is used as an intelligent Point master (SPL), and its basic responsibilities may include at least one of the following: (1) the device is used as a coordinator of the ZigBee network to maintain the normal work of the ZigBee network; (2) the router serving as the WiFi network maintains normal work of the WiFi network and normal interaction between the local area network and the wide area network; (3) coordinating master and slave nodes in a PLC network; (4) local scene control and related services such as association control of two devices, DHCP service, etc.
FIG. 6 shows a communication software architecture diagram according to an embodiment of the invention. The various smartpoints are implemented in the form of agents (agents) in fig. 6. As shown in fig. 6, the main functions of the agent are to manage information of each device under the same transmission mode (such as Zigbee, WiFi, or PLC), forward messages between the device and the Bus (JD Bus), and implement relevant information conversion between different transmission-class intelligent devices, where the agents are Zigbee agent, WiFi agent, PLC agent, BT (bluetooth) agent, and the like.
In the example shown in FIG. 6, the various agents communicate over a BUS (e.g., a JD BUS). It should be noted, however, that the various agents may also communicate with each other via any wired or wireless transmission means, and the invention is not limited thereto.
The communication mode of the intelligent devices preferably selects the agent to which each intelligent device belongs to complete the routing. Fig. 7a to 7c show the communication between heterogeneous smart devices of ZigBee, WiFi and BT types, respectively.
Fig. 7a shows a communication scheme in a ZigBee network. Wherein communication between different ZigBee smart devices (end devices) may or may not pass through the ZigBee coordinator (as shown in fig. 7a with solid and open arrows respectively).
The communication in the WiFi network is shown in fig. 7 b. In a WiFi network, communication between smart devices is accomplished through a WiFi agent.
Fig. 7c shows the communication in the BT network. Likewise, in a BT network, communication between smart devices is also accomplished through their proxies (BT proxies).
However, if the agent (smart point) to which the smart device belongs is unable to complete the communication, for example because the communication is between different types of communication networks, routing needs to be completed between the smart points. In the various reachable networks, one preferred routing rule is: the first is preferably a PLC network, the second is preferably a WiFi network, and the third is preferably a ZigBee network. Fig. 8 shows an example of a routing rule in this case.
As shown by the solid arrows in fig. 8, the BT smart device is connected to smart point a point to point, and smart points a to C can be connected through PLC (via smart point B) and WIFI, respectively. When the BT smart device needs to communicate with the Zigbee end device, as shown by the black arrow direction, the smart point a will preferentially select a route through the PLC, and then pass through the WiFi, from B to C. Finally, the coordinator handed by C to Zigbee completes the routing of e 1. It can be seen that, according to the preferred routing rules described above, even if there is a direct wireless communication path between intelligent point a and intelligent point C, communication from intelligent point a to intelligent point C is accomplished through the PLC network and the WiFi network.
Another example of communication according to the preferred routing rule is also illustrated in fig. 8 by the routes indicated by the outlined arrows. In the Zigbee sub-network of the Zigbee point C, the Zigbee device e2 needs to interact with the Zigbee point B through, for example, a Zigbee gateway (including a Zigbee coordinator), and the routing to the WiFi smart device is completed through the Zigbee point B.
An exemplary routing rule according to an embodiment of the present invention, i.e. selecting a network for routing communications in the order PLC, WiFi, ZigBee, is shown above with reference to fig. 8 by way of example. It will be appreciated, however, that the invention may also be applied to other routing rules, such as other routing rules that refer to network link quality and network load. For example, when smart point B in fig. 8 is loaded above a certain threshold, communication from smart point a to smart point C may bypass smart point B (i.e., bypass the WiFi network), reach smart point C directly through the PLC network (when the PLC network is connected to smart point C), or be routed directly through the path between smart point a to smart point C.
This routing between different points of intelligence may be controlled by a point of intelligence master (SPL). FIG. 9 shows a schematic diagram of SPLs in a Smart Point network environment.
As shown in fig. 9, in the whole smart point network, a smart point S3 (for example, WiFi smart point) functions as SPL, a bluetooth end smart device (BLE) is mounted below S4, no device is mounted below S2, and a ZigBee sub-network is formed below S1. When networking, each device can report its own device information to the affiliated intelligent point, and each intelligent point reports its own information and the stored device information to the SPL. As can be seen from fig. 9, the smart point S3 stores not only information of the subnet managed by the smart point S3 (smart devices W1, W2), but also information of other smart points S1, S2, S4. Such information includes, but is not limited to, device information for the smart point and smart device, protocols used, etc., and may also include any information needed to manage the smart point and its corresponding communication subnet. Thus, any device under intelligence can always route (via SPL) to the target device when it needs to communicate outside the subnet.
As can be seen from the above discussion, this scheme can further improve the practicability of the whole network and the good interaction of the devices when communicating with the outside.
The communication protocol of the smart device is further described below.
Information storage and reporting rule of intelligent equipment
i. The intelligent equipment leaves factory and prefabricates self-related configuration information, and the description information of the intelligent equipment can be written in the following modes: 1. and (2) prefabricating default information when leaving a factory, and writing in by a developer through the intelligent device K.
And ii, after the intelligent device accesses the network, reporting the information of the intelligent device to a direct father node.
For the Zigbee intelligent equipment, the intelligent equipment can interact with the ZigBee gateway through the coordinator, and finally report the information to the direct SP.
For WIFI and BT intelligent devices, information can be directly reported to the directly-affiliated SP.
If there are no children, there is no need to store any information, such as SP2 in FIG. 9.
All SPs report information of themselves and of the smart devices they control to SP3 (SPL).
