So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
Fig. 1 is a schematic flow chart of a communication method of the internet of things provided by the embodiment of the disclosure. As shown in fig. 1, the communication method of the internet of things includes:
s110, receiving an alternative device list sent by a target device under the condition that an initiating device is not adaptive to the target device;
s120, sending a protocol list supported by the initiating device to the alternative devices in the alternative device list;
s130, under the condition that the protocol supported by the alternative equipment is compatible with the protocol in the protocol list, establishing communication connection with the target equipment through the alternative equipment;
specifically, when an initiating device and a target device in the internet of things cannot communicate due to non-adaptation, the target device sends a list of alternative devices with which the target device can communicate to the initiating device; then, the initiating device sends the protocol list supported by the initiating device to the alternative devices in the alternative device list; further, the alternative device compares the supported protocol with the received protocol in the protocol list supported by the initiating device, and if the protocol supported by the alternative device exists in the protocol list supported by the initiating device, it indicates that the alternative device can be adapted to the initiating device, that is, the alternative device can establish a communication connection with the initiating device, so that the initiating device can establish a communication connection with the target device through the alternative device and communicate with the target device.
Here, the initiator device, the target device, and the candidate device may be home appliances, such as an air conditioner, a washing machine, a dryer, etc., or may be terminal devices, such as a mobile phone, a notebook computer, a personal digital assistant, etc., or may also be gateway devices, such as a router, a switch, etc., which are not limited by the embodiments of the present disclosure. Further, the alternative device can be used as an intermediate device in the internet of things, and is used for realizing conversion and distribution of communication protocols among various devices, so that interconnection communication among the various devices can be realized.
The candidate device list may include one or more candidate devices, and when a plurality of candidate devices are included in the candidate device list, the candidate devices may be candidate devices of the same hierarchy or candidate devices of different hierarchies, which is not limited in this disclosure. For example, assume that the candidate device list of the target device Z includes a candidate device B and a candidate device C, the candidate device list of the candidate device B includes a candidate device D and a candidate device E, the candidate device list of the candidate device C includes a candidate device F, and so on. It should be noted that, the number of the alternative devices in the same hierarchy is not limited by the embodiments of the present disclosure, for example, the number of the alternative devices in the same hierarchy may be one, two, three or more.
In addition, the structure of the alternative device list may be a tree topology, that is, the alternative devices in the alternative device list are arranged in a tree. It should be understood that the structure of the alternative device list is not limited to the tree topology as described above, for example, a star topology, a bus topology, a ring topology, a mesh topology, etc., which is not limited by the embodiments of the present disclosure.
A protocol, i.e., a communication protocol, refers to the rules and conventions that must be followed by two entities to complete a communication or service. The protocol defines the format used by the data unit, the information and meaning that the information unit should contain, the manner of connection, and the timing of the sending and receiving of the information, thereby ensuring that the data is smoothly transmitted to a certain place in the network.
Further, the communication Protocol may include, but is not limited to, HyperText transfer Protocol (HTTP), Advanced Message Queuing Protocol (AMQP), Extensible Messaging and Presence Protocol (XMPP), restricted Application Protocol (CoAP), and Message Queuing Telemetry Transport (MQTT) protocols.
It should be noted that the initiator device, the target device, and the alternative device of the embodiments of the present disclosure may support one or more communication protocols.
According to the technical scheme provided by the embodiment of the disclosure, the alternative device list sent by the target device is received under the condition that the initiating device is not adapted to the target device, the protocol list supported by the initiating device is sent to the alternative device in the alternative device list, and the communication connection with the target device is established through the alternative device under the condition that the protocol supported by the alternative device is compatible with the protocol in the protocol list, so that the interconnection communication between the devices can be realized, therefore, the adaptation process between the devices is simplified, the adaptation efficiency is improved, and the user experience is further improved.
In some embodiments, in the case that the protocol supported by the alternative device is compatible with the protocols in the protocol list, establishing, by the alternative device, the communication connection with the target device includes: determining a communication link between the initiating device and the target device under the condition that the protocol supported by the alternative device is compatible with the protocol in the protocol list; sending unique link identification to each device on the communication link one by one; and after receiving the link establishment notification sent by the target equipment, establishing communication connection with the target equipment through the communication link.
Specifically, after receiving the protocol list sent by the initiator, the candidate device compares the supported protocol with the protocols in the protocol list and feeds back the comparison result to the initiator, and if the supported protocol of the candidate device is compatible with the protocols in the protocol list, it indicates that the link between the initiator and the candidate device is communicable, and at this time, the initiator may determine that the link between the initiator and the target device is also communicable, and thereby establish a communication link between the initiator and the target device.
Then, the initiating device sends a unique link identifier to the candidate device adjacent to the initiating device on the communication link, and after receiving the unique link identifier sent by the initiating device, the candidate device stores the unique link identifier and continues to send the unique link identifier to the target device.
Further, after receiving the unique link identifier sent by the alternative device, the target device stores the unique link identifier and sends a link establishment notification to the initiating device to notify the initiating device that the communication link is successfully established; after receiving the link establishment notification sent by the target device, the initiator device may establish a communication connection with the target device through the communication link and communicate with the target device.
Here, a link refers to a physical line from a node to a neighboring node without any other switching node in between, and a node is a node that includes a data element and several branches pointing to other subtrees.
A communication link refers to a physical channel between two nodes in a network. The communication link may be a point-to-point connection communication link, i.e. a link connects only two nodes; the link may also be a multipoint connection link, that is, one link connects multiple nodes, which is not limited in this disclosure.
The link identification refers to flag information of the communication link. For a communication link, its link id is unique, and each device on the communication link needs to carry a unique link id. Further, the link identifier may be a link number, a link name, or a link address, and the like, which is not limited in this disclosure.
According to the technical scheme provided by the embodiment of the disclosure, the unique link identifier is sent to each device on the communication link after the communication link is determined, and the corresponding device can be quickly and accurately found in the subsequent communication process, so that the adaptation time is saved, the adaptation efficiency is improved, and the user experience is further improved.
In some embodiments, the communication method of the internet of things of fig. 1 further includes: the alert message is issued if the alternative device appears on the communication link at least twice.
Specifically, when one or more candidate devices in the same hierarchy or one or more candidate devices in different hierarchies exist in the candidate device list, multiple communication links may exist, and at this time, the multiple communication links need to be judged to screen out the most suitable communication link; further, if the alternative device appears on a communication link twice or more, it indicates that the communication link has a loop, and at this time, a prompt message such as "communication connection failure" is sent out, and the communication link is discarded. Here, the loop refers to a cyclic reciprocation.
For example, assuming that the initiator a attempts to perform a communication connection with the target device Z, since a protocol supported by the initiator a is incompatible with a protocol supported by the target device Z, the initiator a and the target device Z cannot directly establish a communication connection; at this time, the initiating device A tries to perform communication connection with the alternative device B of the target device Z; the protocol supported by the initiating device a is incompatible with the protocol supported by the alternative device B, so that the initiating device a continues to attempt communication connection with the alternative device C of the alternative device B; since the protocol supported by initiating device a is not compatible with the protocol supported by alternate device C, initiating device a continues to attempt a communication connection with alternate device D of alternate device C, and so on, there may be a communication link of "Z-B-C-D-B" that circulates indefinitely due to the occurrence of alternate device B twice in the communication link.
It should be noted that the screening method of the communication links is not limited to discarding the communication links with the loop as described above, for example, the communication link with the shortest time or the communication link with the fewest hierarchies may be selected as the optimal communication link, and the embodiment of the present disclosure does not limit this.
According to the technical scheme provided by the embodiment of the disclosure, the searching speed of the adaptive equipment can be improved by screening the communication links and abandoning the communication links with loops, so that the adaptive time is saved, and the adaptive efficiency is improved.
In some embodiments, the communication method of the internet of things of fig. 1 further includes: and in the case that the protocols supported by the alternative devices are not compatible with the protocols in the protocol list, sending the protocol list supported by the initiating device to other alternative devices in the same layer or alternative devices in the next layer.
Specifically, if the protocol supported by the alternative device is not compatible with the protocols in the protocol list, it indicates that the link between the initiating device and the alternative device is not communicable, and at this time, the initiating device may continue to send its supported protocol list to other alternative devices in the same hierarchy; or after receiving the list of candidate devices capable of communicating with the candidate device sent by the candidate device, sending the list of supported protocols to the candidate device of the next hierarchy until the initiating device finds a device capable of adapting to the initiating device.
According to the technical scheme provided by the embodiment of the disclosure, the alternative device adapted to the initiating device can be found by traversing the alternative devices in the alternative device list, so that the interconnection communication between the initiating device and the target device in the internet of things is realized by taking the alternative devices as intermediate devices.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
