A kind of processing method of cascade Mach-Zehnder interferometer order
Technical field
The present invention relates to a kind of processing method of cascade Mach-Zehnder interferometer order.
Background technology
Increasingly mature along with LED technology, the LED large-screen of overlarge area is just promoted gradually, in the process promoting overlarge area LED large-screen, in order to realize the multi-channel image processor of LED large-screen, the unlimited writing space of art worker can be become a reality, and people have developed the LED video processor supporting multi-channel image processor.
The every profession and trades such as safety monitoring, administration, military commanding, display and demonstration, scientific research and education, in the application of video processor, need multi-channel image processor function.The existing LED video processor in market, generally only can support four split screens, thus causes the performance of site operation wiring and intention to be greatly limited, and then causes very large application puzzlement to user, cannot meet the actual demand of user.As shown in Figure 1, be traditional LED video processor communication load mode, A is main control device, S
1s
nfor N number of controlled device, several LED video processors i.e., this controlled device is responsible for the video frequency output of each split screen in many pictures respectively, hold at whole main control device A, need to process a large amount of and between N number of controlled device return data, data processing amount is very big, under mass data signal intelligence, the situation of error code will be had to occur, and controlled device quantity is more, and reaction speed is slower.In order to reduce the error rate, and considering the disposal ability of main control device A, being not suitable for multiple devices Synchronization Control, so just limit the quantity of controlled device, necessarily limit the quantity of split screen, make the display number of many pictures receive limitation, reduce Consumer's Experience.The present invention is directed to the above-mentioned defect further investigation of prior art video processor, explore practicable solution.
Summary of the invention
The object of the present invention is to provide a kind of processing method of cascade Mach-Zehnder interferometer order, the Computer Vision function of super many pictures can be supported, when not taking input port, by multimachine signal cascade function, improve the quantity of video processor Synchronization Control, realize the display number of many pictures, meet the actual demand of client.
The processing method of a kind of cascade Mach-Zehnder interferometer order of the present invention, wherein, main control device is connected with N number of controlled device connected successively, described each equipment all can send a command to next stage equipment, and all there is a backward channel order can be back to upper level equipment, the next stage equipment of last controlled device is main control device, and the backward channel of main control device is connected to last controlled device, specifically comprises the steps:
Step 1, main control device send command in combination to the N number of controlled device connected successively, and this command in combination comprises the complete order that N number of controlled device needs perform;
The command in combination that step 2, main control device send first is sent in the first controlled device, this first controlled device judges the command in combination received and selects, if belong to the fill order of this equipment, then transfer to this equipment to perform, the order of other non-device processes is then to be sent as the order being handed down to next stage equipment;
After step 3, this equipment execute order, judging whether to exist needs other equipment to coordinate the order performed, if have, then pass back to upper level equipment by backward channel, if there is the result that this equipment needs to reply, then form command in combination with the order of non-device processes of step 2 and be sent to next stage controlled device;
Step 4, controlled device by the order connected successively according to step 2,3 flow process carry out command process, until the result that all controlled devices are replied is returned to main control device as command in combination by last controlled device, main control device is collected in the result of all controlled devices reply, if it is exectorial to relate to secondary, return to the command process that step 1 carries out a new round.
By adopting the processing method of cascade Mach-Zehnder interferometer order of the present invention, single autonomous control system is converted into multiple autonomous control system and carrys out dispersion treatment order, greatly can strengthen the efficiency of command execution, and more equipment carries out joint control, order the efficiency issued higher, the linkage of multiple devices is better.

Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Embodiment
As shown in Figure 2, be main control device A and N number of controlled device (S
1s
n) connected mode, main control device A is connected with N number of controlled device connected successively, above-mentioned each equipment all can send a command to next stage equipment, and all there is a backward channel order can be back to upper level equipment, the next stage equipment of last controlled device is main control device, and the backward channel of main control device is connected to last controlled device.
As shown in Figure 3, the processing method of a kind of cascade Mach-Zehnder interferometer order of the present invention, comprises the steps:
Step 1, main control device A send command in combination to the N number of controlled device connected successively, and this command in combination comprises the complete order that N number of controlled device needs perform;
The command in combination that step 2, main control device A send first is sent to the first controlled device S
1in, this first controlled device S
1judge the command in combination received and select, if belong to the fill order of this equipment, then transfer to this equipment to perform, the order of other non-device processes is then to be sent as the order being handed down to next stage equipment;
After step 3, this equipment execute order, judging whether to exist needs other equipment to coordinate the order performed, if have, then pass back to upper level equipment by backward channel, if there is the result that this equipment needs to reply, then form command in combination with the order of non-device processes of step 2 and be sent to next stage controlled device S
2;
Step 4, controlled device by the order connected successively according to step 2,3 flow process carry out command process, until last controlled device S
nthe result of being replied by all controlled devices returns to main control device A as command in combination, and main control device A collects in the result of all controlled devices reply, if it is exectorial to relate to secondary, returns to the command process that step 1 carries out a new round.
In the present invention, every platform equipment has the command process mechanism of oneself, and ACTIVE CONTROL mechanism, by originally all by the data volume of main control device process, decompose in every platform controlled device of cascade, controlled device leaves the fill order of this equipment, the order of non-device processes is issued to next stage equipment, single control system is converted into the order of multiple autonomous control system dispersion treatment by the present invention, greatly can strengthen the efficiency of command execution, more equipment carries out joint control, order the efficiency issued higher, the linkage of multiple devices is better.
The above, it is only present pre-ferred embodiments, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
