Netty-based large screen visualization platform data push system

The invention discloses a Netty-based large screen visualization platform data push system which comprises a data collection layer, a data set inquiry service layer and a client display layer. The Netty-based large screen visualization platform data push system disclosed by the invention directly pushes data to a relevant subscribed client through an asynchronous and event-driven network application framework, realizes data real-time update, and overcomes the problem that the traditional plugged IO (Input/Output) multithread mode can not meet the requirement of real-time and stable push of large data by a large screen visualization platform.
