And the remote transmission module is mainly used for realizing the remote communication function between the gateway and the M2M open platform.
And the strategy downloading module can remotely download the software updating versions of the primary SSA and the secondary SSA from the M2M open platform.
The user sends the network parameters to the monitoring terminal through the SSA by triggering the SSA in the gateway and the DHCP extension field, and the wireless connection convenience of the monitoring terminal is improved through an SSA software control mode.
Referring to fig. 7, the environment-aware service platform pulls environment data information or pushes control information to the M2M open platform through a standard open interface (e.g., a RESTful API interface), and then displays the environment data information or the push control information on a front-end webpage in real time for a user to perform operations such as monitoring and control.
The user side of the invention refers to a user mobile phone, a tablet personal computer and the like, and the user monitors the change of the environmental data through the Web page of the user side.

The invention accesses the monitoring terminal into the M2M open platform according to the standard access flow and design method provided by the M2M open platform, and the process is roughly divided into several steps of login and registration, new project, new equipment, new data flow, uploading and checking data and new application, and the like, as shown in FIG. 6.
Before accessing the monitoring terminal into the M2M open platform, a user account needs to be registered on the M2M open platform (i.e., a new service platform and system are generated based on the M2M open platform), and after successful registration, a new project can be added under the user account, a new device can be added under the new project, and a new data stream can be added under the device. After the environment data is successfully uploaded, data points will be generated in the corresponding data streams of the platform, and finally, in order to present the changes of the data more intuitively, the user can customize the personalized application and publish it to the application hatcher.
