Data replicating and pasting system and method between intelligent terminals based on UDP and TCP protocols

The invention discloses a data replicating and pasting system and method between intelligent terminals based on UDP and TCP protocols. The system comprises at least two intelligent terminals, each intelligent terminal comprises a data processing module and a shear plate module, the shear plate modules are connected with the data processing modules, the two intelligent terminals are connected in the same local area network, one intelligent terminal is connected with the other intelligent terminal by sending and receiving UDP broadcasts, and the shear plate module in one intelligent terminal is connected with the data processing module of the other intelligent terminal. According to the system and method, text data between the different terminals can be conveniently and rapidly replicated and pasted, replicating and pasting can be directly operated on the terminals, other media are not need, only network connection is needed, the data confidentiality is ensured, information leakage is prevented, meanwhile, cost
