Embodiment
The invention provides a kind of window operation method for synchronous and device of distributed processing system(DPS), can solve the inconsistent problem of demonstration time of prior art window in distributed processing system(DPS).Describe specific embodiments of the invention in detail below in conjunction with accompanying drawing.
Embodiment one
A kind of window operation method for synchronous of distributed processing system(DPS) as shown in Figure 1, comprises the steps:
Step S11, after carrying out corresponding window operation in the control terminal, control terminal will send to Control Server with this window operation of answering instruction of operating mutually, after Control Server receives the window operation instruction of control terminal, create the synchronization object of this window operation, and, send to corresponding display processing device respectively and open the signal source instruction according to window parameter generation lock unit.
Above-mentioned synchronization object is the abstract of a conception of species, and a window operation is operated synchronization object of corresponding generation, and each synchronization object all has unique identify label, and a synchronization object has comprised one or more lock units; In like manner, above-mentioned lock unit also is the abstract of a conception of species, the corresponding unique display processing device of lock unit, be that lock unit and display processing device have unique corresponding relation, and all has unique identify label in the synchronization object of each lock unit under it, in addition, lock unit also has the Status Flag of indicating that whether this lock unit is finished.
Above-mentioned window operation specifically can comprise open the operation of window operation, moving window, operation etc. closes window.Be operating as example with a windowing in the distributed processing system(DPS) and describe step S11 of the present invention in detail: as shown in Figure 2, one total and four corresponding four display processing devices of display unit (being respectively display processing device 1,2,3,4), need open a window in these four display processing devices, each display processing device is responsible for handling the part of window.After then Control Server receives the window operation instruction (being specially the instruction of windowing herein) of control terminal, create the synchronization object of this fenestration procedure, and according to a window parameter generation lock unit, because this fenestration procedure need be finished by display processing device 1,2,3,4, so need to create four lock units (the corresponding display processing device of lock unit), send to these corresponding display processing devices 1,2,3,4 respectively then and open the signal source instruction.
Step S12, corresponding display processing device receive described open the signal source instruction after, be connected to signal source to obtain data and to handle, finish dealing with the back to Control Server send respectively separately open the signal source commanded response (be each display processing device to Control Server all send separately open the signal source commanded response).
Signal source can be the data of Local or Remote, as long-range monitor video data etc.
Step S13, Control Server receives that each display processing device sends over open the signal source commanded response after, find the pairing lock unit of this display processing device in corresponding synchronization object and the synchronization object according to the described signal source commanded response of opening, the Status Flag of this lock unit is made as finishes, and whether the Status Flag of judging all lock units is and finishes.
If the status indication of all lock units is all for finishing, just send window operation instruction after treatment, correspondence, otherwise continue to wait for that the signal source of opening that receives other display processing device responds till the response of receiving all display processing devices to corresponding display processing device.It still is example with Fig. 2, being different from the response that receives a display processing device of the prior art sends the mode of corresponding windowing instruction just for immediately this display processing device, the present invention need be not to be under the completed situation at the status indication of judging all lock units, does not send the windowing instruction to any one display processing device; Respond up to the signal source of opening that receives all display processing devices, promptly the status indication of all lock units is and has finished, and at this time just sends corresponding windowing instruction respectively to display processing device 1,2,3,4.
Step S14, corresponding display processing device carry out window operation according to this corresponding window operation instruction after receiving the window operation instruction of the correspondence that Control Server sends over.The process of carrying out window operation specifically can comprise: disconnection was followed the connection between the signal source and is carried out cleaning work after each display processing device received the shutdown signal sourse instruction; And receive to open window and in window, demonstrate after the windowing instruction and open the data that the signal source process has been handled well among the step S12.
As an embodiment preferably, for each display processing device always is under the optimum load operation state, be unlikely to because some display processing device load too high, thereby make the demonstration of whole image content asynchronous to conversion speed is slack-off, the present invention also introduces a kind of resource management mechanism for display processing device " scoring " to improve method of the present invention, specifically comprise the steps: to mark for the resource of the shared display processing device of signal source in the corresponding display processing device, and in step S12 corresponding display processing device to Control Server send respectively separately open the signal source commanded response in, also send " the resource scoring of shared each display processing device of signal source " of the above-mentioned appraisal result value of representative respectively, described Control Server judges whether each resource scoring surpasses the resource scoring higher limit of the default corresponding display processing device hardware handles of representative ability, if, therefore certain display processing device load too high then is described, sends the shutdown signal sourse instruction and notify the control terminal failure of windowing to the corresponding display processing device of this window operation.
Need to prove, if wherein some display processing devices are handled in a plurality of signal sources of execution simultaneously, then described Control Server need judge whether the summation of the resource scoring that these a plurality of signal sources processing are shared surpasses the resource scoring higher limit of this display processing device hardware handles ability of representative of presetting.For example, the a certain resource scoring higher limit of carrying out the display processing device of a plurality of signal sources processing just at the same time is set to 100, and the shared resource scoring of one of them signal source is 10, the shared resource scoring of another signal source is 20, judge that each resource scoring summation discovery does not surpass default higher limit, then continues the step (step S13) that the Status Flag of lock unit was searched and changed in execution; But if the resource scoring summation of the shared display processing device of signal source in a plurality of signal sources processing of carrying out has simultaneously surpassed the default higher limit of certain display processing device, this display processing device load too high then is described, can not this signal number certificate of normal process, therefore the display processing device of all lock unit correspondences sends the shutdown signal sourse instruction and notifies the control terminal failure of windowing in this synchronization object.
In addition, break down and have influence on whole system, when creating described synchronization object among the step S11, note the time that synchronization object generates, and the time-out time of this synchronization object is set in order to prevent in the distributed system some display processing devices.Whether the time-out time that this synchronization object is set is to be completed when not being judged as not for the status indication when all lock units described in the step S13, except status indication that continue to wait for all lock units all become finished, can also wait for that described synchronization object is overtime, then send corresponding window operation instruction to corresponding display processing device if described synchronization object is overtime.With Fig. 2 is example, the time-out time of supposing setting is 10s, this is a long time, in this time, can suppose that other three display processing devices have all responded to some extent, but Control Server never receives the response message of display processing device 3, then no longer continue to wait for the response of display processing device 3 after the 10s, directly to corresponding display processing device (1,2,3,4) send corresponding window operation instruction respectively, promptly no matter the signal number in the display processing device 3 does not just require each display processing device to carry out corresponding window operation according to also handling well, even if the benefit of doing like this is that fault has appearred in some display processing devices in the distributed system, can not have influence on whole system yet.
