Be described in detail at the distributed processing system(DPS) in the present embodiment below.
In the applied high resolving power display environment of the present invention, as shown in the figure, this high resolving power display environment has two or more a plurality of display units to be spliced, each display unit is corresponding to a part of high resolving power display environment, and this corresponding corresponding relation is stored in main control server.
After each equipment connects, specifically handle before, at first can carry out initialization operation, this initialization operation can comprise:
Each equipment (comprising main control server, treatment facility, display unit etc.) carries out power-on self-test;
Main control server is according to pre-set connecting method, and promptly which treatment facility is corresponding to which display unit, and this display unit is corresponding to which zone in the ultrahigh resolution actual environment, and the environment of distributed processing system(DPS) is carried out initialization;
Treatment facility is connected to main control server, sends link information to main control server, comprises the information such as resolution, color, the degree of depth of this treatment facility self in the link information, waits for that subsequently main control server judges whether the setting of this machine is effective;
Be provided with under the normal situation, main control server sends the viewing area that it is responsible for to treatment facility, i.e. coordinate range in the high resolving power actual environment.
When concrete the processing, open first operational order of window by the man-machine interface input of main control server, comprise in this first operational order and need open a window of determining size in certain position of high resolving power display environment, the information that shows the content of certain signal source has promptly comprised first coordinate range information and the signal source information that need open window.
After main control server receives this first operational order, according to first coordinate range in this first operational order, and the corresponding relation of default each treatment facility, display unit and high resolving power display environment, determine that this window has fallen into the indication range of those display units, promptly this window and which display unit have lap, and this window and which display unit, treatment facility are relevant;
After having determined relevant treatment equipment, main control server calculates described window according to above-mentioned first coordinate range and falls into second coordinate range of the part of described each relevant display unit with respect to the high resolving power display environment, it is second coordinate range that the part of the required demonstration of described each relevant display unit is positioned at described high resolving power display environment, and send second operational order to each treatment facility of correspondence, comprise first coordinate range, second coordinate range and the signal source information of the display unit of each treatment facility correspondence in this second operational order;
