The invention relates to a dispatching method of a timer, in particular to a dispatching method of an annular propulsion timer which carries out real-time communication protocol conversion, data collection and calculation in a secondary real-time monitoring device of an electric system. According to the requirements of the system, the dispatching method comprises the following steps: collecting an integral number; ensuring and establishing head pointers of W=2<m> timer queues; establishing an annular queue; establishing a global tickcount variable with initialization as 0; and scanning, adding and deleting the timer by the tickcount variable, and the like. The dispatching method uses space to exchange time, greatly increases the scanning efficiency by establishing W+1 global variables and circularly propelling the tickcount simultaneously and can quickly position through the tickcount because a large number of timers are dispersed in the W queues, thereby obviously increasing the adding and deleting efficiency.

The invention provides an audio-video sharing method and system. According to the audio-video sharing method and system provided by the invention, a particular sharing transmission means is used; storage and sharing release processing works of audio-video data are completed through an FMS (Flash Media Server); acquired audio and video data after being subjected to encoding through a streaming medium are uploaded with an RTMP (Real Time Messaging Protocol) to the FMS by using an upload terminal; the uploaded audio and video data after being subjected to combination and encoding are released with the RTMP to a share user terminal by using the FMS so that the audio-video data upload and sharing release are simultaneously with real-time transmission performance and the real-time sharing of the audio-video data can be realized; the problem of occupation of the storage space of two-side terminals of the upload and the sharing is solved with the help of the RTMP so that a long time audio-video sharing of a mobile terminal is ensured to be possible; and the audio-video sharing method and system are combined with a sharing service, so that a user is convenient to timely request on the shared audio-video data at different times and places or on terminals, and the service application range is promoted to expand.

The invention provides an RIA (Rich Internet Applications)-based monitoring method which comprises the following steps: A. a server establishes communication channels with a plurality of monitors, and a terminal machine establishes a communication channel with the server; and B. a central monitoring unit installed in the server concurrently processes a business logic processing step, a real-time data push step and a real-time data receiving step, and the central monitoring unit pushes real-time data to a user operation platform installed in the terminal machine in such a way that long-connection data push is combined with an RTMP (Real Time Messaging Protocol).
