Abstract

A method for data sharing among intelligent equipment based on a file system relates to the field of mobile intelligent equipment software, is applicable to mobile intelligent equipment and enables transparent sharing of data among equipment and automatic data updating to be realized. The method comprises the following steps: a sharing end module uploads sharing data to a server, and then sets the data sharing mode, the updating method and the sharing optimization strategy of intelligent equipment; a sharing end file system organizes data sharing information into sharing information and sends the sharing information to a server end, and after the sharing data is updated, the updated data is sent to the server end; the server end receives the sharing information, establishes a sharing association relationship, and copies or links the data to a shared directory of the server according to the set updating method; and a shared end file system generates an update request, receives the sharing information, confirms sharing according to a local access control table and receives sharing data. The method of the invention has the characteristics of being transparent to users and applications, high in degree of automation, easy to use and the like.

Description

technical field [0001] The invention relates to the field of mobile data sharing, in particular to a method for sharing data between embedded smart devices based on a file system. Background technique [0002] In recent years, with the rapid popularization of 3G networks, various smart devices, such as smart phones, smart cars, and smart home appliances, have increasingly entered people's daily lives, changing people's usage habits. In particular, the rise of wearable devices such as Google glass and Samsung gear smart watches has led to a variety of smart devices and emerge in endlessly. The mobile Internet data report released by Youmeng in the first half of 2013 shows that in the second quarter of 2013, China’s active smart devices have exceeded 500 million, of which there are 340 million active Android devices and 150 million active iOS devices. doubled the number of active devices. In addition, due to the activeness of the Internet of Things, people are inseparable fr...
