In order to facilitate understanding of the technical scheme of the application, the communication method of the Internet of things in the application is described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic flow diagram corresponding to a transmission flow in an internet of things communication method according to an embodiment of the present application.

As shown in fig. 1, an embodiment of the present application corresponding to a transmission flow in an internet of things communication method includes:

101. The first IOT terminal detects a send request that invokes the IOT device communication interface.

The sending request is used for indicating to send communication protocol data to the second internet of things IOT terminal, the IOT device communication interface is generated based on an object model of the IOT terminal, and the object model of the IOT terminal is defined based on an object model description language TSL.

The communication protocol data is transmission data between the first IOT terminal and the second IOT terminal, and specifically, the communication data includes, but is not limited to, request data or response data. For example, the first IOT terminal sends the request data to the second IOT terminal, and after receiving the request data, the second IOT terminal sends the corresponding response data to the first IOT terminal.

The object model defined by the TSL is formed by digitally representing entities in physical space from three dimensions of attributes, services and events, wherein the entities can comprise intelligent lamps, sensors, vehicle-mounted devices and the like.

By taking an intelligent lamp as an example, the generation of the communication interface of the IOT device based on the object model of the IOT terminal is described as follows:

FIG. 2 is a schematic diagram of an IOT device communication interface generated based on an object model of a smart lamp in an embodiment of the application.

As shown in fig. 2, the intelligent lamp is input into the IOT device model, the IOT device model obtains the object model of the intelligent lamp through the TSL description definition in three aspects of device attribute, device action and device event, and finally a unified interface, namely, the IOT device communication interface, is generated according to the object model of the intelligent lamp defined by the TSL description. It should be understood that for a smart light, a device service is the device action of the smart light. For example:

describing the device attributes of the intelligent light by the TSL includes: 1. a switch, 2, brightness;

Describing the device actions of the intelligent light through the TSL includes: 1. setting a switch attribute, 2, reading the switch attribute, 3, setting a brightness attribute, and 4, reading the brightness attribute;

Describing the device event of the intelligent light through the TSL includes: 1. trademark switch changes, 2, reporting brightness changes.

Further, the unified interface generated based on the intelligent lamp object model described by the TSL includes: 1. the method comprises the steps of requesting to set a switch attribute, 2 responding to set the switch attribute, 3 requesting to set a brightness attribute, 4 responding to set the brightness attribute, 5 requesting to report a switch change, 6 responding to report the switch change, 7 requesting to report the brightness change, 8 responding to report the brightness change.

102. And aiming at the sending request, the first IOT terminal codes the communication protocol data according to the target coding format to obtain a first data packet.

The encoding format is used to encode data for transmission. The target encoding format may include, but is not limited to, a JS object profile (javascript object notation, JSON) encoding format or a protocol buffer (protocol buffer) encoding format of a cross-platform serialized data structure.

The two further coding modes Protobuf and JSON are essentially different for the coding modes of data: 1. for the data coding mode of Protobuf, after the data structure object is serialized into binary data, the binary size is more economical than that of the JSON coding mode, and is usually 15% -70% of the binary data obtained by the JSON coding mode. 2. For the JSON data coding mode, binary data after the serialization of the data structure object is plaintext, which is more friendly to APP or Web development, and the analysis of the JSON data is more convenient in the debugging stage.

Due to the coding characteristics of the JSON coding format and the Protobuf coding format, the application discovers that the JSON coding format is suitable for coding communication protocol data transmitted by high-bandwidth communication technologies such as Wi-Fi or 4G-LTE, and the Protobuf coding format is suitable for coding communication protocol data transmitted by low-bandwidth communication technologies such as Bluetooth BLE or Zigbee, so that the communication transmission efficiency and reliability can be effectively ensured.

Optionally, in an implementation manner of the embodiment of the present application, when a transmission bandwidth of a current transmission link layer is a high bandwidth, the target encoding format is a JSON encoding format; when the transmission bandwidth of the current transmission link layer is low bandwidth, the target coding format is a Protobuf coding format.

The specific implementation manner of the first IOT terminal for encoding the communication protocol data according to the target coding format to obtain the first data packet is different due to the different target coding formats. The above operations may be implemented in the present application by an RPC framework code library generated according to an IOT device communication interface. Specifically, after detecting the sending request, the first IOT terminal invokes an IOT device communication interface in the RPC framework code library through a calling function, and then encodes communication protocol data according to a target encoding format to obtain a first data packet. Optionally, the IOT device communication interface includes a request interface and a response interface.

Further specifically, in one implementation manner of the embodiment of the present application, when the transmission bandwidth of the current transmission link layer is a high bandwidth, the first IOT terminal encodes the communication protocol data according to the target encoding format to obtain the first data packet, and may specifically perform the following operations:

The first IOT terminal packages the binary byte stream into a first data packet according to a high bandwidth communication transport protocol. From the above operation, it can be seen that in the case that the transmission bandwidth of the current transmission link layer is high, the JSON object generated by the communication protocol data is directly serialized into a binary byte stream through the RPC frame code library, and then the binary byte stream is packed into the first data packet.

Illustratively, when the current transport link layer is at a high bandwidth, the RPC frame code library directly sequences JSON objects into binary byte streams via the JSON serializer and deserializer, and then passes the binary byte streams of communication protocol data (e.g., request data or response data) to the protocol transport layer, which packages the binary byte streams into complete first packets. The RPC frame code library comprises the program codes corresponding to the JSON serializer and the anti-serializer.

Further specifically, in one implementation manner of the embodiment of the present application, when the transmission bandwidth of the current transmission link layer is a low bandwidth, the first IOT terminal encodes the communication protocol data according to the target encoding format to obtain the first data packet, and may specifically perform the following operations:

Similarly, as can be seen from the above operation, in the case that the transmission bandwidth of the current transmission link layer is low, firstly, the JSON object generated by the communication protocol data is converted into a Protobuf object through the RPC frame code library, secondly, the Protobuf object is serialized into a binary byte stream, and finally, the binary byte stream is packed into the first data packet.

For example, when the current transmission link layer is in a low bandwidth condition, the RPC framework code library firstly converts JSON objects of communication protocol data (such as request data or response data) into Protobuf objects through a JSON and Protobuf inter-converter; secondly, the Protobuf object is serialized into a binary byte stream through the Protobuf serialization and deserializer, and finally, the binary byte stream of the communication protocol data is transferred to a protocol transmission layer, and the protocol transmission layer packages the binary byte stream into a complete first data packet. The RPC frame code library comprises the JSON and Protobuf interconverter and the Protobuf serialization and inverse serialization program codes corresponding to the inverse serializer.

The RPC frame code library can uniformly manage the transmission link interfaces of the bottom layer, and select a specific current transmission link interface according to the availability of the transmission link, so that the RPC frame code library can obtain the transmission bandwidth of the current transmission link. For example, currently configured to the RPC framework are three underlying transport links, wi-Fi, 4G-LTE and BLE; when 4G-LTE (high bandwidth) is off, the RPC framework selects Wi-Fi (high bandwidth), and when Wi-Fi is also off, the RPC framework selects BLE (low bandwidth).

It should be appreciated that the above-described packing of the binary byte stream into the first data packet by the first IOT terminal according to the high or low bandwidth communication transport protocol is accomplished at the transport protocol layer.

103. And the first IOT terminal encapsulates the first data packet according to the link protocol to generate an encapsulated second data packet.

The link protocol corresponds to the current transmission link layer and is used for packaging the data packet so as to ensure the reliability of data transmission. Specifically, the first IOT terminal sequences the first data packet according to the current transmission link layer and packages the first data packet into a second data packet of a complete corresponding link protocol.

Specifically, in the case of high bandwidth transmission, the first IOT terminal transmits the first packet sequence through a transmission link layer and packages the first packet sequence into a complete second packet corresponding to a link protocol of the low bandwidth communication technology such as Wi-Fi or 4G-LTE.

In the case of low bandwidth transmission, the transmission is performed through a low bandwidth communication technology such as BLE or Zigbee, at this time, the first IOT terminal packages the first data packet sequence into a complete second data packet corresponding to the link protocol of the low bandwidth communication technology such as BLE or Zigbee through the transmission link layer.

104. And the first IOT terminal sends a second data packet to the second IOT terminal through the IOT equipment communication interface.

After the second data packet is obtained through packaging, the first IOT terminal sends the second data packet to the second IOT terminal through the IOT device communication interface.

Specifically, when the current transmission link is high bandwidth, the first terminal uses a Wi-Fi or 4G-LTE high bandwidth communication technology and sends the second data packet to the second IOT terminal through the IOT device communication interface.

Similarly, when the current transmission link is low bandwidth, the first terminal uses a low bandwidth communication technology such as BLE or Zigbee, and sends the second data packet to the second IOT terminal through the IOT device communication interface.

In summary, in the embodiment of the present application, firstly, the first IOT terminal detects a transmission request for calling the IOT device communication interface, secondly, for the transmission request, the first IOT terminal encodes communication protocol data according to a target encoding format to obtain a first data packet, and finally, the first IOT terminal passes through the IOT device communication interface generated according to the object model of the IOT device. Because the communication interface of the IOT equipment is uniformly defined for the object model of the IOT equipment based on TSL definition, the uniform communication interface of the IOT equipment can be compatible with different coding formats to carry out coding transmission on the data packet, and the service expansion and service realization capacity of the IOT equipment can be improved.

It should be understood that in the embodiment corresponding to fig. 1, the first IOT terminal is used as a transmitting end, and the second IOT terminal is used as a receiving end to describe the communication mode of the internet of things in the present application, specifically, the embodiment corresponding to fig. 1 is described in terms of the transmitting end, and the technical scheme of the receiving end will be described with reference to the accompanying drawings.

Fig. 3 is a schematic flow diagram corresponding to a receiving flow in the communication method of the internet of things according to an embodiment of the present application.

As shown in fig. 3, an embodiment of the present application corresponding to a receiving flow in an internet of things communication method includes:

301. and under the condition that the detection module detects that the communication interface of the IOT equipment receives the second data packet sent by the IOT terminal of the first Internet of things, the second IOT terminal analyzes the second data packet according to the link protocol to obtain the first data packet.

The communication interface of the IOT device is generated based on an object model of the IOT terminal, the object model of the IOT terminal is defined based on an object model description language TSL, and the link protocol corresponds to the current transmission link layer.

Specifically, the second IOT terminal parses the second data packet according to the link protocol corresponding to the current transmission link layer to obtain the first data packet. Further, the parsed first data packet enters the protocol transport layer.

Under the condition of high-bandwidth transmission, the second IOT terminal transmits through a high-bandwidth communication technology such as Wi-Fi or 4G-LTE, and at the moment, the second IOT terminal analyzes the second data packet through a transmission link layer according to a link protocol of the high-bandwidth communication technology such as Wi-Fi or 4G-LTE to obtain the first data packet.

In the case of low bandwidth transmission, the second IOT terminal performs transmission through low bandwidth communication technologies such as BLE or Zigbee, and at this time, the second IOT terminal analyzes the second data packet through the transmission link layer according to the link protocol of the low bandwidth communication technologies such as BLE or Zigbee to obtain the first data packet.

302. And the second IOT terminal decodes the first data packet according to the target coding format to obtain communication protocol data.

After the parsed first data packet enters the protocol transmission layer, the second IOT terminal decodes the first data packet according to the target coding format to obtain communication protocol data.

Specifically, the target encoding format may include, but is not limited to: JSON coding format or Protobuf coding format. The difference between these two coding formats is detailed in the description of the relevant part in step 102, and will not be repeated here.

Corresponding to the sending flow, the second IOT terminal in the present application may also implement the above operation through an RPC framework code library, where the RPC framework code library is generated according to the IOT device communication interface. Specifically, the second IOT terminal may call the IOT device communication interface in the RPC framework code library by calling a function, and then decode the first data packet according to the target encoding format to obtain the communication protocol data. Also optionally, the IOT device communication interface includes a request interface and a response interface.

Similarly, in one implementation of the embodiment of the present application, when the transmission bandwidth of the current transmission link layer is a high bandwidth, the target encoding format is a JSON encoding format; when the transmission bandwidth of the current transmission link layer is low bandwidth, the target coding format is a Protobuf coding format.

Further specifically, in one implementation manner of the embodiment of the present application, when the transmission bandwidth of the current transmission link layer is a high bandwidth, the second IOT terminal decodes the first data packet according to the target coding format to obtain the communication protocol data, and may specifically perform the following operations:

Illustratively, when the current transmission link layer is in a high bandwidth condition, first, the second IOT terminal parses the first data packet into a binary byte stream according to a high bandwidth communication transmission protocol (e.g., wi-Fi or 4G-LTE); secondly, the second IOT terminal uses a calling function to call a JSON serialization and deserializer in the RPC frame code library to deserialize the binary byte stream into a JSON object; and finally, the second IOT terminal uses the calling function to call codes in the RPC framework code library to decode the JSON object to obtain communication protocol data.

Further specifically, in one implementation manner of the embodiment of the present application, when the transmission bandwidth of the current transmission link layer is a low bandwidth, the second IOT terminal decodes the first data packet according to the target coding format to obtain the communication protocol data, and may specifically perform the following operations:

Illustratively, when the current transmission link layer is in a low bandwidth condition, first, the second IOT terminal parses the first data packet into a binary byte stream according to a high bandwidth communication transmission protocol (e.g., wi-Fi or 4G-LTE); secondly, the second IOT terminal uses a calling function to call a Protobuf serialization and deserializer in an RPC frame code library to deserialize the binary byte stream into a Protobuf object; thirdly, the second IOT terminal uses the calling function to call a JSON and Protobuf inter-converter in the RPC frame code library to convert the Protobuf object into a JSON object; and finally, the second IOT terminal uses the calling function to call codes in the RPC framework code library to decode the JSON object to obtain communication protocol data.

To sum up, in the embodiment of the present application, first, when the second internet of things IOT terminal detects that the IOT device communication interface receives the second data packet sent by the first internet of things IOT terminal, the second IOT terminal parses the second data packet according to the current transmission link layer to obtain the first data packet, and finally, the second IOT terminal decodes the first data packet according to the target coding format to obtain the communication protocol data. Because the communication interface of the IOT equipment is uniformly defined for the object model of the IOT equipment based on TSL definition, the uniform communication interface of the IOT equipment can be compatible with different coding formats to carry out coding transmission on the data packet, and the service expansion and service realization capacity of the IOT equipment can be improved.

Further, the second IOT terminal uses an RPC frame code library to determine that the target coding format is a Protobuf or JSON coding mode according to the transmission bandwidth of the current transmission link, and further the second IOT terminal decodes the first data packet according to the target coding format to obtain communication protocol data, and the RPC frame code library is generated according to the communication interface of the IOT device. Because the unified communication interface of the IOT equipment can be compatible with different coding formats to carry out coding transmission on the data packet, the RPC frame code library generated based on the communication interface of the IOT equipment can be compatible with multi-terminal equipment and multiple programming languages, the maintainability of a developer on the communication interface of the IOT equipment can be improved, and the development period of project codes can be shortened.

As can be seen from the embodiments described in fig. 1 and fig. 3, the first IOT terminal encodes the communication protocol data according to the target encoding format to obtain the first data packet, and the second IOT terminal decodes the first data packet according to the target encoding format to obtain the communication protocol data, which may be implemented by using the RPC frame code library, which will be described below.

Fig. 4 is a flowchart of an embodiment of an RPC frame code library according to an embodiment of the present application.

As shown in fig. 4, the RPC framework code library in the embodiment of the present application includes: the interface transmission data packaging module, the request function module and the response function module, wherein the three modules comprise corresponding function modules, and the function modules can be realized through program codes.

The RPC framework code library is generated from the IOT communication device interface. Illustratively, as shown in fig. 4, generating a unified interface based on the object model of the intelligent lamp in fig. 2 to generate the RPC frame code library shown in fig. 4, where the object model of the intelligent lamp generates the unified interface includes: 1. setting a switch attribute interface, wherein the interface specifically is used for requesting to set a switch attribute and responding to set the switch attribute in fig. 2; 2. a set brightness attribute interface, which specifically sets brightness attributes for the request and sets brightness attributes in response to the request in fig. 2; 3. reporting switch attribute interfaces, specifically the request reporting switch changes and the response reporting switch changes in fig. 2; 4. the reporting brightness change interface is specifically the request reporting brightness change and response reporting brightness change in fig. 2.

The interface transmission data packaging module comprises the following functional units: JSON data structure diagram Schema, protobuf data structures diagram Schema, JSON and Protobuf interconverter, JSON serializer and deserializer, and Protobuf serializer and deserializer.
