Automatic update method of embedded terminal based on over the air (OTA) technology

Abstract

The invention relates to an automatic update method of an embedded terminal based on the OTA technology and belongs to the technical field of embedded terminal update. A system comprises the embedded terminal and an OAT update server, wherein the OAT update server comprises a Soap server and a download server, and the embedded terminal submits a request for updating a data packet when an embedded terminal user starts the embedded terminal each time; the Soap server sends update information to the embedded terminal according to the request of the embedded terminal; and the embedded terminal determines whether to request the download server for update according to the data returned by the Soap server. The automatic update method has the advantages that the method is not limited to mobile terminals and the OTA technology is applied to the embedded terminal; storage and management problems of the embedded terminal system and software are solved, and server resources are effectively used; the system and the software are maintained and managed uniformly by the server, security is guaranteed, and deployment and maintenance are reduced simultaneously; and automatic download is supported and user experience is improved.
