System and method for realizing user interface interaction through remotely controlling data terminal

The invention provides a system and a method for realizing user interface interaction through remotely controlling a data terminal. The system comprises at least one data terminal with a user interface, and at least one host in network connection with the data terminal in a B/ S framework, wherein the host acquires information of the data terminal, generates an analog interface for simulating the user interface of the data terminal according to the acquired information, receives an operational command sent by a user through the analog interface, and sends the operational command to the data terminal through a network; the data terminal receives the operational command from the host, executes the operational command, displays an execution result of the operational command in the user interface, and sends the execution result as information of the data terminal to the host. The system simulates the user interface of the data terminal by a flash technology for performing remote interaction with the user, has the characteristics of convenience in using, rapid response and good user experience effect, and provides a data terminal experiencing service and a remote terminal testing service for the user.
