detailed description

For the problem that the heterogeneous Internet of Things terminal access platform is difficult, the embodiment of the present invention provides an apparatus and method for accessing the Internet of Things terminal. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting.

As shown in FIG. 1 , an apparatus for accessing an Internet of Things terminal in the embodiment of the present invention includes:

The information transceiver module 100 is configured to receive an uplink message reported by the terminal.

The plug-in module 120 is configured to convert the reported uplink message into an uplink message conforming to the platform communication protocol of the platform according to the first terminal communication protocol of the terminal.

The terminal communication protocol includes a CoAP protocol, an LWM2M protocol, and an MQTT protocol; and the platform communication protocol includes a OneM2M protocol.

In the embodiment of the present invention, the device converts various types of terminals and various terminal communication protocols through plug-in modules, and finally converts them into a data model defined by the platform, thereby accessing the platform, and effectively solving the heterogeneous Internet of Things terminal connection. In the embodiment of the present invention, the device is flexible in operation and strong in extensibility, and provides a good solution for the platform to access various types of terminals. In the embodiment of the present invention, the device is compatible with various terminal types. Into, it is conducive to platform use and promotion.

On the basis of the above-described embodiments, the modified embodiments of the above-described embodiments are further described. It is to be noted that, in order to simplify the description, only the differences from the above-described embodiments are described in the respective modified embodiments.

In an embodiment of the present invention, the plug-in module is further configured to acquire a second terminal communication protocol of the downlink terminal;

Decoding, according to the second terminal communication protocol of the downlink terminal, a downlink message of the platform into a downlink message that conforms to the second terminal communication protocol of the downlink terminal;

The information transceiver module is further configured to send a downlink message that meets the terminal communication protocol of the downlink terminal to the downlink terminal.

That is to say, the plug-in module provides a protocol conversion function, and is responsible for converting the communication protocol of the terminal uplink message into the communication protocol of the Internet of Things platform; and also converting the communication protocol of the platform downlink message into the communication protocol of the terminal. For example, the platform usually adopts the OneM2M protocol. For the LwM2M protocol terminal, the plug-in module needs to implement the mutual conversion between the LwM2M protocol and the OneM2M protocol. The plugin module needs to follow a uniform interface, and the plugin container generates a plugin instance, which is called. The plug-in module has public properties, such as the version, name, classification, and interface of the plug-in. The plug-in also has personalized private attributes, such as the LwM2M protocol and the OneM2M protocol, which can define the message transmission format of the LwM2M protocol terminal.

The second terminal communication protocol in the embodiment of the invention may be the same as or different from the first terminal communication protocol in the previous embodiment.

Further, the device further includes:

a protocol obtaining module, configured to obtain, by using the reported uplink message, a first terminal communication protocol of the terminal Negotiation.

Specifically, the plug-in module includes:

a packet parsing unit, configured to parse the reported uplink message according to the first terminal communication protocol of the uplink terminal;

The data packet parsing unit is further configured to parse the downlink message of the platform according to the platform communication protocol;

Of course, in a specific implementation, the plug-in module may further include an interface module. That is, the data packet parsing unit parses the data packet according to the terminal protocol type for the uplink message, and encapsulates the data packet according to the terminal communication protocol type for the downlink message;

The protocol conversion unit implements conversion of the terminal protocol type and the platform protocol type. For example, the LwM2M terminal and the OneM2M protocol type terminal can implement protocol conversion according to TS-0014-LWM2M_Interworking.

The interface module is used by the plug-in module to provide a unified calling interface, which is called for the plug-in container, thereby realizing the functions of the plug-in module.

In another embodiment of the present invention, the plug-in module is at least one, and the attributes of each of the plug-in modules are different; the device further includes:

a plugin container for storing plugin modules;

That is to say, the plug-in configuration module provides plug-in configuration methods, setting plug-in property parameters, etc.; for example, the parameters set by the LwM2M protocol and the OneM2M protocol conversion plug-in are: version number, plug-in name, protocol conversion type, Interface implementation class, message data encoding format, etc. After adding a plugin configuration on the plugin configuration module, the plugin container dynamically checks and creates the plugin instance in the plugin container, and the plugin container monitors the plugin to run, and the plugin container schedules the plugin to execute. When the plugin configuration module deletes a plugin configuration, the plugin container also dynamically checks and deletes the plugin instance in the plugin container. After the plugin is deleted, the plugin will no longer provide the conversion function service of the protocol.

The plugin container module is a module for managing plugins. It is responsible for loading and unloading plugins according to the plugin configuration module, and monitoring the operation of the management plugins. The plugin container can also choose to dispatch appropriate plugins and provide a unified interface for platform calls to implement plugin function services.

Certainly, the device may further include a service processing module, where the service processing module is a core module of the service processing of the Internet of Things platform, and is responsible for processing each business process and storing service data; for example, the Internet of Things platform provides data storage, Terminal communication, message forwarding, link management, terminal registration, terminal message reporting, remote control terminal command, parameter configuration delivery, etc.

Further, the plugin container module can include:

The plugin loading module is responsible for checking the plugin configuration module. For the newly added plugin, the plugin loading module creates an instance of the plugin and puts it into the plugin container;

The plug-in management module, the plug-in instance in the plug-in container, is monitored and managed by the plug-in management module. Manage the plugin's running state, load time, and plugin parameters. When the plugin performs an exception, the plugin management module is responsible for recreating the plugin instance.

The plugin scheduling module, the plugin scheduling module maintains a classification of each plugin, and the classification of each plugin is unique within the plugin container. When the protocol is converted, the plugin scheduling module selects the same type of plugin according to the type of the message message. Then call the protocol conversion function provided by the plugin to implement protocol conversion. For example, when the LwM2M protocol terminal sends a registration message, the plug-in scheduling module determines that the protocol type of the terminal is the LwM2M protocol type, then selects the LwM2M protocol and the OneM2M protocol conversion plug-in, and then invokes the plug-in interface to complete the conversion of the LwM2M protocol and the OneM2M protocol. That is to say, when the terminal interacts with the platform, the plug-in scheduling module needs to select and dispatch a suitable plug-in module, and convert the terminal communication protocol into a platform communication protocol through the protocol adaptation function of the plug-in module. For example, the terminal communication protocol selects the LWM2M protocol, and the platform usually uses the OneM2M protocol. In this case, the LWM2M conversion protocol plug-in needs to be selected, and the LWM2M protocol is converted into the OneM2M protocol by using the protocol conversion function of the plug-in.

The plugin uninstall module, when the plugin configuration module deletes the configuration of a plugin, the plugin container detects and calls The plugin uninstalls the module and deletes the plugin instance. The uninstalled plugin no longer provides the service functionality of the plugin.

A specific application example is used to describe an access process of the device in the embodiment of the present invention;

The process of sending an uplink message by the terminal includes:

Step 11: The uplink terminal reports a data packet (that is, an uplink message). Under normal circumstances, the terminal needs to send its own device information, status data, etc. to the platform, and the platform provides it to the user or a third party.

Step 12: When receiving the data reported by the terminal, the information transceiver module of the platform first needs to parse the data packet.

Step 13, the plug-in container module of the platform selects a plug-in module corresponding to the data packet. For example, if the data packet sent by the terminal is a datagram of the CoAP protocol, the plug-in container should select the plug-in module of the OneM2M protocol by using the CoAP protocol. If the data packet sent by the terminal is the data packet of the LwM2M protocol, the plug-in container module should select LwM2M. The protocol converts the plugin module of the OneM2M protocol.

Step 14. After selecting the plug-in, the plug-in module interface can be called to perform protocol conversion, and the terminal datagram format is converted into a OneM2M protocol format. Usually, the platform selects the OneM2M protocol.

Step 15: After converting the data packet to the OneM2M protocol, the service processing module of the platform can perform the corresponding service operation.

The platform sends a downlink message flow, including:

In step 21, the platform sends a downlink message. The platform needs to send a downlink terminal control message, such as a subscription notification message.

In step 22, the plugin container module selects the plugin module. When sending the downlink message, the plug-in container module selects the corresponding plug-in module according to the communication protocol type of the downlink terminal.

In step 23, the plugin module is called to perform protocol conversion.

In step 24, the converted data is encapsulated and then sent to the terminal.

The invention further provides an Internet of Things terminal access method.

As shown in FIG. 2, an access method for an Internet of Things terminal in an embodiment of the present invention includes the following steps:

S201. Receive an uplink message reported by the uplink terminal.

S202. Convert the reported uplink message into an uplink message conforming to the platform communication protocol of the platform according to the first terminal communication protocol of the uplink terminal.

Further, the method may further include:

Obtaining a second communication protocol of the downlink terminal,

Before the step of converting the reported uplink message into an uplink message conforming to the platform communication protocol of the platform, the method further includes:

Obtaining, by the reported uplink message, a terminal communication protocol of the terminal.

The terminal communication protocol includes a CoAP protocol, an LWM2M protocol, and an MQTT protocol; the platform communication protocol includes a OneM2M protocol.

The method in the embodiment of the present invention converts various types of terminals and various terminal communication protocols through protocol adaptation, and finally converts into a data model defined by the platform, thereby accessing the platform; when the downlink message is delivered, the protocol is adapted. The conversion is finally converted into a data model defined by the terminal to implement interaction with the terminal. The method is flexible in operation and extensible, and provides a good solution for the platform to access various types of terminals. This method is reasonably compatible with various terminal type accesses, which is beneficial to platform use and promotion.
