The invention relates to a coordinated and interactive operating method of an intelligent device, which comprises a means of connection, a means of collection, a means of work division, a means of back transmission and a means of updating and optimization, and is characterized in that the means of connection refers that electronic devices are connected with a cloud processing assembly or a local work division processing master control terminal; the means of collection refers that user information is collected through sensors of the electronic devices; the means of work division refers that the collected information is transmitted to the cloud processing assembly or the local work division processing master control terminal, and then the information is handed to a cloud data center to operate or divided to each electronic device to process; the means of back transmission refers that the information processed by the means of work division is transmitted back to the cloud processing assembly to the local work division processing master control terminal, and an instruction is transmitted to the electronic devices according to a result so as to enable the electronic devices to perform an action which is the most appropriate to users; and the means of updating and optimization refers that behaviors and operations of the users are observed, analysis is performed on the behaviors and operations of the users and the instruction transmitted back by the cloud processing assembly or the local work division processing master control terminal, comparison data is accumulated, and modification is performed on the transmitted instruction. According to the method provided by the invention, information integration and coordinated work division are performed on the electronic devices, a behavior pattern of a new user is learnt and updated, and intelligent life experience is realized.
