The invention provides a data interaction method for embedded equipment and a server. The server comprises a detection module, a storage module and a communication interface module, wherein the detection module is used for detecting data link requests of clients in real time and establishing links with the clients if the link requests are valid; the storage module includes service areas in one-to-one correspondence with the clients and is used for storing request data of the clients; and the communication interface module is used for allowing an application layer to call the stored data from the service area, and analyzing and processing the data. According to the data interaction method for the embedded equipment, by separating the data processing of the application layer and a bottom layer, the data processing of the application layer is not affected by receiving, transmitting and storage of the data at the bottom layer, the data processing of the bottom layer is also not affected by the data processing of the application layer, thus the data coupling of the bottom layer and the application layer is reduced, and an emerging problem is easy to locate.
