And the embodiments and features of the embodiments in the present specification may be combined with each other without conflict.
Fig. 2 is a first flowchart of a near field communication method based on multiple protocols according to an embodiment of the present invention, where the near field communication method based on multiple protocols may be applied to a relay node or a forwarding node in a near field communication network, that is, a first node, where the first node is an M-N node that supports multiple protocols and has a function of interconversion between multiple protocols. As shown in fig. 2, the method for near field communication based on multiple protocols may include the following steps:
Step 201: a first node receives a message; the first node supports multiple protocols and has a function of interconversion among multiple protocols; the message comes from a second node or a controller and carries the address of the target equipment of the message; the target device is the second node or the controller;
Step 202: converting the message into a protocol supported by the target device;
Step 203: and sending the message after the protocol conversion to the target equipment.
In a specific implementation, the multi-protocol in the embodiment of the present invention may include: existing short-range Communication protocols such as bluetooth protocol, WiFi protocol, IrDA (Infrared Data Association) protocol, NFC (Near Field Communication), ZigBee protocol, UWB (Ultra Wide Band) protocol, Z-wave Alliance (Z-wave Alliance) protocol, and Near Field Communication protocols that may appear in the future.
The second node can be an M-N node supporting multiple protocols or an S-N node supporting a single protocol; the M-N nodes can have the function of mutual conversion among a plurality of protocols;
with the landing and the implementation of the internet of things, the types and the number of the terminals of the internet of things will grow explosively and may become the main form of the terminals in the future. Protocols supported by the internet of things terminal are diversified, and the ZigBee protocol is not the only choice for different application scenes.
the embodiment of the invention provides a near field communication method based on multiple protocols based on a near field multi-protocol cooperative communication system. Fig. 3 is a schematic structural diagram of a near field communication system based on multiple protocols in an embodiment of the present invention, as shown in fig. 3, in the near field multi-protocol cooperative communication system, the system includes a Controller and a Node, where the Controller may further include controllers (M-C) supporting multiple protocols and controllers (S-C) supporting a single protocol. The nodes may include nodes (M-N) that support multiple protocols and nodes (S-N) that support a single protocol. Each node can communicate with the corresponding controller through one or more M-N node relays, or can directly communicate with the corresponding controller without passing through the relay node. Similarly, each controller may relay communications with its corresponding node through one or some M to N nodes, or may directly communicate with its corresponding node without passing through a relay node. The controllers, nodes in the close range multi-protocol cooperative communication system may support one or more of the above-mentioned multi-protocols.
the embodiment of the invention provides an M-N node, which not only supports multiple protocols, but also has the function of mutual conversion among multiple protocols. Fig. 4 is a schematic diagram of a functional structure of M-N nodes in the embodiment of the present invention, and as shown in fig. 4, the M-N nodes may have a node protocol selection module to select which protocol to convert a received message into according to protocol conditions supported by a source node and a sink node in a communication process; and the protocol conversion module is used for carrying out protocol conversion on the received message according to the selection result of the protocol selection module. Therefore, the M-N nodes can act as relay nodes for protocol mapping and forwarding between different protocol nodes.
because the M-N nodes supporting conversion among various protocols are provided for relaying, the defect that the multi-protocol gateway cannot communicate when a problem occurs in the multi-protocol gateway when a multi-protocol gateway scheme is adopted in the prior art can be effectively avoided.
In the method and the device for near field communication based on multiple protocols provided by the embodiment of the invention, a first node supporting multiple protocols and having a function of interconversion among the multiple protocols receives a message from a second node or a controller, wherein the message carries an address of a target device of the message, and the target device is the second node or the controller; after the first node converts the message into the protocol supported by the target device, the message after the protocol conversion is sent to the target device, so that the problem that the existing multi-protocol gateway and the terminal have communication faults or cannot communicate beyond the communication distance can be solved, the first node is effectively utilized to forward the message between the node and the controller of the node, and the near field communication efficiency is improved.
in implementation, the converting the message into the protocol supported by the target device may specifically include:
determining a protocol supported by both the first node and the target device;
if the protocol supported by the first node and the target device is one, converting the message into the protocol type;
if the protocols supported by the first node and the target device are multiple, comparing the transmission distances of the messages of the protocol types, and determining the protocol with the maximum transmission distance of the messages;
and converting the message into the protocol type with the maximum transmission distance.
In the implementation, in the short-range communication, some protocols have a longer transmission distance, such as: wifi, Zwave, zigBee are about 100 meters or so, and some protocols have a short transmission distance, such as: bluetooth is within about 10 meters.
when the protocol supported by both the first node and the target device is only one, the protocol type of the received message is converted into the protocol type supported by both the first node and the target device.
when there are multiple protocols supported by the first node and the target device, the transmission distances of messages of the multiple protocols supported by the first node and the target device may be compared, and in order to reduce the number of relay nodes as much as possible, the protocol with the largest transmission distance of the message may be determined and the received message may be converted into the protocol type with the largest transmission distance.
Fig. 5 is a schematic diagram of forwarding by using a long-distance protocol in the embodiment of the present invention, as shown in fig. 5, when an S-N node supporting only a bluetooth protocol leaves its controller S-C beyond an effective coverage, the S-N node and the controller S-C are interrupted in communication, and the S-N node may select one M-N node from a local selection neighbor node list to be relayed to the controller S-C. And if one M-N node relay is not selected to be connected to the controllers S-C, selecting the M-N node closest to the S-N node to be connected to the controllers S-C through the Bluetooth protocol relay. In order to avoid excessive M-N nodes from being selected into the relay link, the M-N nodes capable of supporting protocols such as a long-distance protocol ZigBee and the like are selected as much as possible. The protocol which can be remotely transmitted is selected among the selected M-N nodes through the protocol selection module, once the relay link is established through the relay transmission module, the command message between the S-N nodes and the controllers S-C is relayed through the M-N nodes, so that the remote communication between the nodes and the controllers can be ensured, and the complementation among different distance transmission protocols is realized.
in implementation, the converting the message into the protocol supported by the target device may specifically include:
When messages of a plurality of second nodes are received and carry the address of the same target device, determining the protocols supported by the first node and the target device;
If the protocol supported by the first node and the target device is one, converting the message into the protocol type;
If the protocols supported by the first node and the target device are multiple, comparing the communication rates of the messages of the protocol types, and determining the protocol with the maximum communication rate;
Converting the message into a protocol type with the maximum communication rate; alternatively, the first and second electrodes may be,
when messages of a plurality of controllers are received and carry the address of the same target device, determining the protocol supported by both the first node and the target device;
If the protocol supported by the first node and the target device is one, converting the message into the protocol type;
If the protocols supported by the first node and the target device are multiple, comparing the communication rates of the messages of the protocol types, and determining the protocol with the maximum communication rate;
And converting the message into the protocol type with the maximum communication rate.
in the implementation, the wireless link may have unstable communication link quality due to environment (e.g., interference, coverage), such as jitter, delay, rate reduction, or even interruption. Close range communication protocols also face the problem of instability of these wireless links. In the near field communication, some protocols have high transmission rate, such as: WiFi and Bluetooth are about 1Mbps or above, and some protocols have lower transmission rates, such as: ZigBee, Zwave, is within about 250 Kbps.
When a first node receives a plurality of messages of a plurality of nodes or a plurality of messages to be controlled and a target device of the plurality of messages is the same, in order to improve the efficiency of the first node in relaying the plurality of messages, when the protocol type of the messages is converted, a protocol with the maximum communication rate supported by both the first node and the target device may be selected as much as possible.
fig. 6 is a schematic diagram of forwarding by using a high-rate protocol in the embodiment of the present invention, and as shown in fig. 6, when link quality deteriorates in an M-N node supporting a low-rate protocol ZigBee and an S-N node supporting a low-rate protocol Zwave, the M-N node and the S-N node may select an M-N node in a locally cached neighbor node list to assist in relaying a message to a controller M-C. As shown in fig. 4, when the second node is poor or abnormal in communication with the controller of the second node and a plurality of second nodes determine that the same first node forwards a message to the controller of the same second node, the M-N nodes may further include a convergence judgment module, configured to establish communication with the controllers M-C by using a high-speed protocol bluetooth (or WiFi) to assist in relaying the message when finding that there are messages from different nodes M-N and S-N that are sent to the same controller M-C. Similarly, when the communication between the node and the controller is abnormal and a plurality of controllers select the same M-N node to forward the message to the same node, the M-N node can also forward the messages of the plurality of controllers to the node by adopting a high-rate protocol Bluetooth (or WiFi) to assist in relaying the message, so that the communication quality can be ensured and the complementation between different transmission rate protocols can be realized.
