Embodiment 1

[0038] like figure 1 As shown, the present invention provides a kind of LWM2M client and host computer data communication method, and this method comprises the following steps:

[0039] S101. Obtain the registration status of the LWM2M client (Client), and determine whether the registration of the client device is completed;

[0040] We know that the LWM2M protocol defines three logical entities, which are provided with data interaction interfaces, and there are four logical interfaces between these three logical entities:

[0041] First, Device Discovery and Registration; this interface allows the client to register with the server and notify the server of the capabilities supported by the client (simply speaking, which resources Resource and Object are supported.

[0042] Second, Bootstrap; Bootstrap server configures Clinet through this interface, such as the URL address of LWM2Mserver.

[0043] Third, Device Management and Service Enablement; this is the most important b...

Embodiment 2

[0067] Based on the same inventive concept, the present invention also provides a data communication device between a LWM2M client and a host computer, which includes:

[0068] The communication module (modem) is used to obtain the interactive data of the LWM2M client (Client) and the LWM2M server;

[0069] The client MCU is configured to analyze and process the interaction data and control whether the communication module provides AT commands.

[0070] Wherein, the interaction data includes the registration state of the LWM2M client (Client), and the write data message (Write) and the monitoring message (Observe) issued by the LWM2M server.

Embodiment 3

[0072] Based on the same inventive concept, the present invention also provides a data communication system between the LWM2M client and the host computer, which includes:

[0073] The communication module (modem) is used to obtain the interactive data of the LWM2M client (Client) and the LWM2M server and report to the upper computer MCU in the form of AT commands;

[0074] The client MCU is used to analyze and process the interaction data and control whether the communication module provides AT commands;

[0075] The upper computer MCU is used to analyze and process the interaction data reported by the LWM2M server, and then return a judgment result to the LWM2M server in the form of an AT command.

[0076] Wherein, the interaction data includes the registration state of the LWM2M client (Client), and the write data message (Write) and the monitoring message (Observe) issued by the LWM2M server.

[0077] Wherein, the write data message (Write) is reported to the upper comput...

Abstract

The invention discloses a data communication method, device and system between a LWM2M client and an upper computer. The method includes the following steps: obtaining the registration status of the LWM2M client (Client), and judging whether the registration of the client device is completed; the LWM2M The client performs data interaction with the LWM2M server (Server); the LWM2M server issues a write data message (Write) and reports it to the upper computer MCU through an AT command; the upper computer MCU reports the write data to the LWM2M server The message (Write) is analyzed to determine whether to execute the write command of the LWM2M server. This application solves the problem that the logical entity defined based on the LWM2M protocol cannot directly perform data interaction with the upper computer MCU.

Description

technical field [0001] The present invention relates to the technical field of data interaction of Internet of Things equipment, in particular to a method, device and system for data communication between an LWM2M client and a host computer. Background technique [0002] The Internet of Things refers to a huge network formed by combining various information sensing devices to collect in real time any required information such as objects or processes that need to be monitored, connected, and interacted, and combined with the Internet. Its purpose is to realize the connection between things and things, things and people, and all things and networks, so as to facilitate identification, management and control. The IoT industry includes five layers: support layer, perception layer, transport layer, platform layer, and application layer. The sensing layer and transport layer of the Internet of Things have many participating manufacturers, making it the most competitive field in t...
