Offline device batch activation method, system, and related products

By using UDP broadcast and TCP connection to obtain the address and information of offline devices within the local area network, and combining this with activation credentials generated in the cloud, efficient batch activation of offline devices is achieved. This solves the limitation of manual intervention in existing technologies, improves activation efficiency, and simplifies the process.

AI Technical Summary

Technical Problem

The existing offline device activation method requires manual activation of one device before other devices can be activated in batches. This makes the activation process cumbersome and time-consuming when deploying large-scale devices, and cannot achieve efficient batch activation.

Method used

The device address is obtained by sending UDP broadcast packets to the target local area network, a TCP connection is established to obtain device information, and activation credentials generated in the cloud are used to achieve batch activation. Data transmission is carried out within the local area network using UDP and TCP protocols without manual intervention.

Benefits of technology

It enables efficient one-time batch activation of offline devices, simplifies the activation process, improves activation efficiency, and ensures the integrity and security of devices during the activation process.

Abstract

The application relates to the field of information technology, in particular to a batch activation method and system for offline devices and related products, which quickly obtains the addresses of all target offline devices in a target local area network through a UDP data communication mode, establishes a TCP data communication connection according to the addresses, obtains the device information of the target offline devices by sending TCP data packets, requests a cloud to generate activation credentials required for activation by using the obtained device information, and re-distributes the activation credentials to the target offline devices, so that the target offline devices complete batch activation by using the activation credentials. Unlike the prior art, the application does not have to rely on manual activation of one offline device first, and then use the manually activated offline device as a bridge to activate the remaining devices. The application is not limited in this way, and the efficient batch activation purpose is achieved, the one-time batch activation of offline devices is truly realized, the activation process is simplified, and the activation efficiency of the offline devices is greatly improved.
