The invention provides a multi-feature fusion video news abstract extraction method, and the method obtains a video news basic processing unit through the lens dividing and lens calibrating of original video news. The method comprises the steps: carrying out the theme caption detection of the video news basic processing unit in the static video abstract through corner detection, color filtering and morphological analysis, and obtaining news main figure information through face identification and clustering; carrying out the silencing analysis of the video news basic processing unit in a dynamic video abstract, and obtaining silencing segments; judging whether each silencing segment contains theme caption or not: adding the theme caption to a final abstract sequence if each silencing segment contains theme caption, and vice versa; and thereby obtaining meaningful high semantic dynamic and static video abstracts. The method can obtain the static abstract, and can flexibly browse and organize the video contents. The obtained dynamic abstract comprises abundant multimedia information, can clearly represent the contents of an original video, and is high in entertainment and ornamental values.

The household photovoltaic intelligent control system can avoid large-scale system design and a construction process of a photovoltaic application system, and no electricity is wasted.

The invention discloses a Web application based terminal audio video data communication method and device. The method comprises steps of receiving connecting request information forwarded by a Web RTC server, wherein the connecting request information carries identity information of a first HTML5 application, and the first HTML5 application is a Web application in a first terminal; determining, according to the identity information of the first HTML5 application, whether to accept the connecting request forwarded by the Web RTC server, if yes, establishing a Web RTC data connection channel between a second HTML5 application and the first HTML5 application, wherein the second HTML5 application is a Web application in a television; and receiving, through the established Web RTC data connection channel, video audio data information sent from the first HTML5 application and displaying the audio video data information. In existing intelligent devices, video and audio stream information cannot be conveniently sent to other terminals of the network side at any time any place, and users cannot watch real-time video on a large screen or perform audio video communication. The method solves above problems in the prior art.

The invention discloses an organic and inorganic compound passivation solution and a passivation method. The passivation solution comprises, by mass, 20.0-35.0% of citric acid, 5.0-15.0% of phytic acid, 0.5-2.0% of cerous nitrate, 2.0-3.0% of sodium molybdate, 2.0-3.0% of triethanolamine, 1.0-5.0% of nanometer silicon sol dispersion liquid, 1.0-5.0% of water-borne acrylate, 1.0-5.0% of gama-(2,3-epoxy propoxy) propyl trimethoxy silane, 2.0-10.0% of sodium dodecyl sulfate and the balance water. The passivation method comprises the steps of stainless steel product pretreatment, surface acid passivation, cleaning, drying and the like.

The invention discloses a voice communication method and system for intelligent hardware and a terminal. The method comprises the steps that the intelligent hardware receives a message channel selected by a user, receives first voice data input by the user in the message channel and sends the first voice data, identification information of the intelligent hardware and the identification information of the message channel to a server according to a confirmation instruction of the user; the server determines account information of a plurality of application programs corresponding to the message channel of the intelligent hardware according to the identification information of the intelligent hardware and the identification information of the message channel; and the server sends the first voice data to the terminal where the corresponding application program is located based on the account information of the corresponding application program, the terminal receives the first voice data sent by the server and sends second voice data to the corresponding intelligent hardware. By adopting the method, the voice communication user demand of the intelligent hardware with a plurality of terminals in a scene with relatively strong social property is satisfied, and the user experience of the user to the intelligent hardware is improved.

The invention provides a Bluetooth power control method and terminal equipment. When the terminal equipment is connected with opposite-end equipment through Bluetooth, the equipment type or the service type of the opposite-end equipment can be obtained to determine whether the opposite-end equipment is equipment in a preset high-power mode; therefore, the terminal equipment sends the data packet to the opposite-end equipment in the high-power mode, and furthermore, after the equipment type of the opposite-end equipment is determined to be the equipment in the preset high-power mode, the transmission power can be determined to be improved according to the request of the opposite-end equipment or the quality of the data link or whether the Wi-Fi coexistence condition is met or not.
