Detailed Description
Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The present disclosure proposes that a node (for ease of distinction, may be referred to as a first node) may be provided inside the gateway. The first node may be a software module or a hardware entity. In other words, the first node may be a node implemented by a software module, i.e. a virtual device node; or may be a physical node implemented based on a hardware entity, i.e. a real device node.
Thus, the gateway described in this disclosure may include a gateway device and a first node. The gateway device is used for realizing data transmission between the nodes and the server, and the first node is used for sending data to the server and/or receiving data sent by the server.
Taking data transmission in the LoRaWAN as an example, the gateway may refer to a LoRa gateway, and the node may refer to a LoRa node. The description of the gateway will be further described with reference to the gateway as a LoRa gateway and the node as a LoRa node, and it should be understood that the description of the LoRa gateway below may be applicable to other types of gateways, and the description of the LoRa node below may also be applicable to other types of equipment nodes.
Fig. 1 shows a schematic block diagram of the structure of a LoRa gateway according to one embodiment of the present disclosure. As shown in fig. 1, the LoRa gateway 100 includes a gateway device 110 and a first LoRa node 120.
Gateway device 110 is used to enable data transmission between the LoRa node and the server. Briefly, gateway device 100 may forward received uplink data sent by a LoRa node to a server, and forward downlink data sent by the server to a corresponding LoRa node. The Server refers to a LoRa Server, and may include, but is not limited to, a Network Server (NS for short), and an application Server (Application Server AS for short). The structure and data transmission principle of the gateway device 110 are not the focus of the present disclosure, and will not be described herein.
First LoRa node 120 may send data (i.e., upstream data) to the server via one or more LoRa gateways as if it were actually present in the LoRa network, and receive data (i.e., downstream data) sent by the server via one or more LoRa gateways. The LoRa gateway through which the first LoRa node 120 sends the uplink data and the LoRa gateway through which the downlink data is received may be the same or different. The LoRa gateway through which the first LoRa node 120 transmits and receives data may be the LoRa gateway 100 or another LoRa gateway in the network.
1. Network access flow of first LoRa node
First, a brief description will be given of the network access flow of the first LoRa node.
The network access process of the first LoRa node is consistent with the LoRaWAN protocol. The first LoRa node is the same as the other LoRa nodes for the server. That is, the server does not perceive the distinction between the first LoRa node and the other LoRa nodes, and processes the first LoRa node's network access request as it processes a real LoRa node's network access request in the network.
Fig. 2 shows a schematic flow chart of the network entry flow of the first LoRa node.
As shown in fig. 2, the first LoRa node may send a network access request to the server through the LoRa gateway, and receive a network access response sent by the server through the LoRa gateway. After receiving the network access response, the first loRa node can analyze the network access response to obtain relevant network access configuration information.
As an example, the first LoRa node may generate a JOIN REQUEST frame (i.e., an inbound REQUEST message) to send to the LoRa gateway. The LoRa gateway that received the JOIN REQUEST frame may be sent to the server via the GWMP protocol. In response to the network access request, the server may return a joni_accept frame (i.e., an access response message) to the LoRa gateway, which sends the joni_accept frame to the first LoRa node. The joni_accept frame may include, but is not limited to, a session key and DevAddr information, where the DevAddr information is used to characterize the identification information of the first LoRa node. For specific parameters in the join_request frame and the join_accept frame, reference may be made to the network access mechanism of the LoRa node in the existing LoRa wan protocol, which is not described herein. After receiving the joni_accept frame, the first LoRa node may parse the joni_accept frame to obtain the session key and DevAddr.
2. Enhanced functionality of a LoRa gateway
Data reporting function
By introducing the first LoRa node 120 at the side of the LoRa gateway 100, a data reporting function can be given to the LoRa gateway 100. For example, the LoRa gateway 100 may be used as a bridge for data transmission between the LoRa node and the server, or may be used as a "LoRa node" to report the self data of the LoRa gateway 100 to the server via the first LoRa node 120.
Fig. 3 shows a schematic flow chart of a data transmission method according to one embodiment of the present disclosure.
Referring to fig. 3, first LoRa node 120 may follow the LoRa wan protocol, with data being upstream to the server through one or more LoRa gateways present in the network. The data sent by the first LoRa node 120 may refer to the data of the LoRa gateway 100 itself, that is, the data of the LoRa gateway 100 may be uploaded to a server by using the first LoRa node 120. For example, the LoRa gateway 100 may report its own device attribute information to the server via the first LoRa node 120.
The LoRa gateway 100 may further receive the downlink data sent by the server, and determine whether the LoRa node for which the downlink data is directed is the first LoRa node 120 set inside the LoRa gateway 100. In the case where the LoRa node for which the downstream data is determined to be the first LoRa node 120, the LoRa gateway 100 may forward the downstream data to the first LoRa node 120, and/or in the case where the LoRa node for which the downstream data is determined not to be the first LoRa node 120, the LoRa gateway 100 may transmit the downstream data to the corresponding LoRa node in a radio frequency manner following the LoRa wan protocol.
Therefore, under the action of the first LoRa node 120 built in the LoRa gateway 100, the LoRa gateway can also report the equipment attribute information of the LoRa gateway 100 to the server as a "LoRa node", and receive the instruction issued by the server, so that the equipment attribute of the LoRa gateway is fully utilized.
The data uploaded by the first LoRa node may also be data from other LoRa nodes in the network (which may be referred to as second LoRa nodes for ease of distinction). The second LoRa node may be a LoRa node that is actually present without being attached to another LoRa gateway, or may be a LoRa node that is disposed inside another LoRa gateway.
That is, the LoRa gateway 100 may also receive data sent by other LoRa nodes (i.e., the second LoRa node) in the network and upload the data of the second LoRa node to the server using the first LoRa node. Optionally, after receiving the data from the second LoRa node, the LoRa gateway 100 may also send the data of the second LoRa node to other LoRa nodes using the first LoRa node.
Data parsing function
In view of communication security, most of data sent by the LoRa node is data encrypted by a key, and the key is configured by a server for the LoRa node during network access.
In order to be able to parse the received LoRa data, the LoRa gateway 100 may also receive the key issued by the server and send the key to the first node 120, so that the first node 120 can parse the data of other LoRa nodes received by the LoRa gateway 100 based on the key.
As one example of the present disclosure, each LoRa node in the network where the LoRa gateway 100 is located corresponds to one key, and the keys used by different LoRa nodes to transmit data are different. The server may send the keys of the plurality of second LoRa nodes to the first LoRa node, i.e. the first LoRa node may store the keys of the plurality of second LoRa nodes.
As another example of the present disclosure, all the LoRa nodes in the network where the LoRa gateway 100 is located may share one key. The server may send the key to the LoRa gateway 100 and the key is sent by the LoRa gateway 100 to the first LoRa node 120 inside the LoRa gateway 100 as well as to other LoRa nodes in the network (i.e., the second LoRa node). The server can issue the secret key to the LoRa nodes in the multicast address range at one time, or issue the secret key to different LoRa nodes in sequence.
The LoRa gateway 100 may also process the parsed data and output the processing result. The operations in which data is processed may be performed by the first LoRa node 120. Thus, the LoRa gateway 100 can process LoRa data. The processing result may be output by the LoRa gateway 100. In addition, the processing result may be output by other LoRa nodes, that is, the LoRa gateway 100 may also send the processing result to other LoRa nodes.
3. Application scenario
By arranging the first LoRa node at the LoRa gateway side, the LoRa gateway can have data reporting capability and data analyzing capability. Therefore, the data processing logic of the server side can be sunk to the LoRa gateway, and the LoRa gateway can analyze and process the data of the LoRa node in the network. The operations of analyzing and processing the data of the LoRa node can be executed by the first LoRa node built in the LoRa gateway, so that modification of processing logic of the LoRa gateway is reduced.
Thus, the present disclosure can build a LoRa network consisting of LoRa nodes and LoRa gateways. That is, the constructed LoRa network includes a LoRa gateway and one or more second LoRa nodes, the LoRa gateway having a first LoRa node disposed therein. The built LoRa network can comprise a server, the server can be used for node registration and key issuing, and the data processing on the LoRa node can be performed by the LoRa gateway.
Thus, the present disclosure may be applicable to, but not limited to, local application scenarios such as smart building, smart hotel, smart home, smart business, smart office, smart building, etc.
The LoRa node in the local application scene can send the data to the LoRa gateway, and the first LoRa node in the LoRa gateway analyzes and processes the received data. The processing result can be output by the LoRa gateway or output by other LoRa nodes.
Fig. 4 illustrates a local key issuing flow diagram according to one embodiment of the present disclosure.
As shown in fig. 4, as an example, the constructed LoRa network may include a LoRa node A, loRa node B, loRa gateway, where the first LoRa node provided on the LoRa gateway side is a virtual LoRa node.
The server transmits the local key to all physical nodes and virtual nodes, and the nodes store the corresponding local key. Specifically, the server may issue the local key (i.e., the keys of all the LoRa nodes in the local LoRa network) to the LoRa gateway, which sends the local key to the virtual LoRa node, loRa node a, and LoRa node B, respectively.
Fig. 5 shows a schematic diagram of a LoRa data processing flow according to one embodiment of the present disclosure.
As shown in fig. 5, the LoRa node a may uplink local data. After receiving the local data of the LoRa node A, the LoRa gateway can forward the local data to the virtual LoRa node. The local data is parsed by the virtual LoRa node by the local key. After the analysis is completed, the virtual LoRa node can upload the local data to the server side. Wherein the data uploaded to the server side may be only used for server recording, and the server may not perform processing operations on the uploaded data.
After the virtual LoRa node analyzes, the analyzed data can be encrypted and then sent to the LoRa node B, or the analyzed data can be processed, and the processed data can be encrypted and then sent to the LoRa node B.
In the present disclosure, the LoRa node and the LoRa gateway may use the LoRaD2D protocol (collectively LoRa Device to Device communication protocol) for data transmission. The LoRaD2D protocol can well meet the scene requirements of lower power consumption, faster response time and local control by realizing the functions of long preamble wakeup and local data control. In the lored 2D protocol, the gateway may continuously send a long wakeup packet, the node periodically opens a window to listen for the gateway wakeup packet, and then opens the receiver entirely after detecting the preamble belonging to itself.
Taking the smart home scenario as an example, besides being used as a bridge for data transmission between the LoRa node and the server, the LoRa gateway itself has equipment properties, for example, the LoRa gateway can also be used as an audible and visual alarm, however, the equipment properties of the LoRa gateway are not considered in the prior art. And the LoRa gateway only performs data circulation at present, and has no method for analyzing and processing local data.
The virtual LoRa node arranged on the LoRa gateway side provides a lightweight solution, enhances the capability of the gateway, and can solve the problems that the attribute of the gateway self equipment cannot be reported and the gateway cannot analyze local data. In the present disclosure, all devices in the network can be regarded as LoRa devices, which are convenient for users to operate, and provide the gateway with the capability of centralized control of local data.
The disclosure also provides a LoRa data transmission method, comprising: setting a first LoRa node in the LoRa gateway; the data is uploaded to the server using the first LoRa node. Details concerning the method may be found in the above related description, and are not repeated here.
The disclosure also provides a LoRa data processing method, which includes: setting a first LoRa node in the LoRa gateway; receiving a secret key sent by a server; transmitting the key to the first LoRa node and the one or more second LoRa nodes; receiving data sent by a second LoRa node through a LoRa gateway, wherein the data is encrypted by a key; forwarding the data to a first LoRa node; and analyzing the data by the first LoRa node based on the key to obtain the analyzed data. Details concerning the method may be found in the above related description, and are not repeated here.
