The invention is suitable for the technical field of communication, and provides a method for sending and sharing contents between terminals and the corresponding terminals. The method includes the following steps: the first terminal and the second terminal start the sharing function; a screen interface of the second terminal is mapped to a screen of the first terminal; the first terminal selects the to-be-shared contents to a path of the second terminal in the display interface of the first terminal; the to-be-shared contents selected by the first terminal are sent to the second terminal; the second terminal automatically receives and saves the shared contents and updates the interface. The method is easy to operate, and interaction between the terminals is visual and convenient to achieve.

The invention provides a distributing type meeting method based on an SIP protocol, which comprises the following steps: meeting IDs of various meetings are preset, and the connection between a meeting originator and meeting participants of various meetings is established according to the meeting ID; during the process of the meeting, the meeting originator sends a first meeting notification to the meeting participants according to the meeting ID; and the meeting participants acquire the attribute information of other meeting participants of the meeting according to the first meeting notification. According to the technical scheme provided by the invention, the probability of the false operation of the user is decreased; meanwhile, the attribute information of other meeting participants of the same meeting is sent to the meeting participants by the meeting originator in the manner of the first meeting notification according to the meeting ID, so that each meeting participant can get the attribute information of other meeting participants in the meeting, the interactive quality of the meeting information is improved, and the user can get a better meeting effect; therefore, the distributing type meeting method based on an SIP protocol is particularly suitable for simultaneously holding various meetings under the distributing type meeting structure.

The invention relates to an online identification and visualization method for power grid disturbances based on multi-resolution wavelet analysis, which belongs to the technical field of wide-area dynamic monitoring and visualization of power systems. The method comprises the following steps: carrying out offline simulation analysis on the features of typical dynamic disturbance accidents in power grid, and selecting a wavelet function Psi and the decomposition layer-number I corresponding to the obtained maximum wavelet coefficient energy as online wavelet multi-resolution analysis tools; carrying out regionalization according to the PMU (power management unit) configuration situation of a target power grid, so that each region has one and only one PMU substation for measurement, and transmitting frequency signals measured by each PMU substation to a WAMS (wide area measurement system) master station; acquiring frequency signals of each PMU substation from the WAMS master station, and carrying out I-layer online wavelet multi-resolution analysis on the frequency signals by using the determined wavelet function so as to obtain wavelet coefficients of an I(th) layer; and discriminating disturbance occurrence time, disturbance occurrence potion and disturbance type according to the wavelet coefficients; and carrying out visualized display through taking a map as the background. The method disclosed by the invention can improve the running reliability of an electrical power grid.
