All types of M2M devices, such as sensor devices, M2M terminal devices, etc., have the same interface specifications and communication specifications, which will increase the actual production and manufacturing costs of M2M devices. For example, for the sensing device of the Internet of Things, it is generally provided by different manufacturers.

The management system can manage the device by establishing a proprietary protocol with the device, so that it is not required. The use of a unified management specification for all devices can reduce the management cost of the device and reduce the production cost of the device manufacturer.

The private protocol communicates; the management platform is connected to the management terminal and communicates through the communication protocol.

Here, the Μ2Μ communication protocol may be a device management protocol (MDMP), a wireless device communication protocol (WMMP, Wireless M2M Protocol), or the like. Here, the M2M management terminal and the M2M device may be a wired connection or a wireless connection. Here, the M2M management terminal is configured to establish a connection with the managed M2M device, save an operation parameter required for the operation of the M2M device, and/or a state parameter for indicating an operation state of the M2M device, and/or Or data collected by the M2M device, and/or control parameters for controlling the M2M device to perform an action;

The M2M management platform is configured to send the M2M management terminal for controlling the

Here, the process of establishing a connection between the managed device and the management terminal may include the step of authenticating the device, and after the authentication is passed, the device accesses the management system successfully, and the device succeeds. The management system can manage the device, otherwise, the device fails to access the management system, and the management system cannot manage the device. Specifically, if the connection is established through a wired connection, the foregoing authentication process may be implemented through an authentication authentication interface, for example, by inputting a password for authentication, etc.; if the connection is established through a wireless manner, the authentication method that can be adopted by the wireless protocol may be adopted. Implement the above authentication process, for example, Bluetooth search.

For example, the management terminal can support a plug-and-play mode, and the connection interface of the device is inserted into the authentication interface of the management terminal, and when the management terminal recognizes that there is a device access, the device is immediately assigned a unique identifier. Such as the device name, or a timestamp accurate to milliseconds.
