Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
The online printing equipment of dynamic data that the present invention proposes a kind of asynchronous many shower nozzles of the present invention, can be used in the online print system of dynamic data, as the print engine running on main frame.Described printing equipment is printed mainboard controller by main frame peripheral interface and rear end and is connected, and for printing mainboard controller, provides each shower nozzle required real time print data stream.The present invention does not rely on feedack in mainboard controller, thus do not inquire about the additional communication expense of mainboard controller, but carry out distribute data bandwidth by a kind of forecasting mechanism, avoid affecting the speed of print system.
Fig. 1 is a topological schematic diagram of the online printing equipment of dynamic data of asynchronous many shower nozzles of the present invention.Fig. 2 is another topological schematic diagram of the online printing equipment of dynamic data of the present invention's asynchronous many shower nozzles of the present invention.
The online printing equipment of dynamic data of asynchronous many shower nozzles that the present invention proposes, mainly comprises that make-up editor unit, inactive data packet pool, the queue of outgoing data bag, annular token bucket (also can be referred to as annular token), print data maker and data send scheduler.
Printing equipment provides visual edit interface for wanting printed matter, and handled easily personnel input space of a whole page content and parameter information.For fear of the effective bandwidth of waste data transmission, the horizontal and vertical spacing of each shower nozzle does not adopt the mode of filling empty print data, but makes each shower nozzle have independently make-up editor unit.Each nozzle printing scope by separately independently edit cell limit, at the correct position of described make-up editor unit, set the content that wish is printed.The content that wish is printed is with the form tissue of occupy-place assembly and components values, and occupy-place assembly is placed on the correct position of described make-up editor unit as required.The actual print image of every part of printed matter is produced by the mode of constantly updating components values.The situation that has certain horizontal spacing for each shower nozzle, the present invention converts the relative position relation of each shower nozzle to the amount of delay of each nozzle printing trigger pip, and sends it to printing mainboard controller.Described printing mainboard controller provides asynchronous print trigger according to amount of delay information for each shower nozzle.
Printing equipment is in advance from internal memory of system application, and this internal memory is formatted as and take the inactive data packet pool that packet is unit, and this internal memory is split into the packet of fixed size in order to follow-up recycling.
Each shower nozzle sending order to be given out a contract for a project is determined by annular token bucket.Element in annular token bucket is package identification, is starting to carry out an initialization before printing, and its initialization is to define initial period shower nozzle workspace and cycle stage shower nozzle workspace, and the packet in these two sections of regions is carried out to the predistribution of package identification.Initial period shower nozzle workspace refers to the print area between shower nozzle front and the most last when firm startup is printed.Printing equipment is analyzed the position relationship between each shower nozzle of initial period shower nozzle workspace and stock, according to the package identification in this section of region of position relationship predistribution, package identification is hung to the afterbody into annular token bucket successively.The identifier of this region allocation, after data transmission scheduler reads, is no longer entered in annular token bucket.Print area after cycle stage shower nozzle workspace refers to and starts between front and the most last shower nozzle of normal printing stage continuously, the package identification in this section of region of same predistribution, and package identification is hung to the afterbody into annular token bucket successively.The identifier of this region allocation, after data transmission scheduler reads, is still hung to the afterbody into annular token bucket, according to the order of sequence to recycle.The identifier distributing for initial period shower nozzle workspace is only used once; And the identifier distributing for cycle stage shower nozzle workspace is still hung successively into recycle from the afterbody of annular token bucket after being used for the first time.
From the head of annular token bucket, often read a sign, just according to this sign, from the outgoing data bag queue of corresponding shower nozzle, take out an outgoing data bag.A plurality of outgoing data bags are spliced and copied in another continuous buffer memory respectively after header part adds the identifier of upper nozzle, be sent to and print after mainboard controller, copied outgoing data bag is returned in inactive data packet pool.
Printing equipment is set up independently outgoing data bag queue for each shower nozzle, print data maker is monitored the size of each shower nozzle outgoing data bag queue, when certain shower nozzle outgoing data bag queue size does not reach total printing umber of setting lower than certain threshold value and the data-switching number of times that started for this shower nozzle, the startup print data generative process of corresponding shower nozzle once just.In the print data transfer process of each shower nozzle, by new components values, upgrade the assembly in space of a whole page edit cell, the make-up editor unit after upgrading is drawn and rasterization process in internal memory, then by the spray orifice rule of shower nozzle, be converted into new print data.The Digital Realization of a corresponding a printed matter of print data transfer process.
After the make-up editor unit of each shower nozzle being upgraded with new data in print data transfer process, in internal memory, draw print image and be rasterized into bitmap form, then bitmap being converted into the data that are applicable to nozzle printing according to the spray orifice position of each shower nozzle.Then use the packet taking out from inactive data packet pool to encapsulate print data, and hang the afterbody into the outgoing data bag queue to setting up for each shower nozzle.
Data send scheduler and are responsible for to each shower nozzle dynamic assignment data bandwidth, determine currently should take out outgoing data bag from the outgoing data bag queue of which shower nozzle.Data send scheduler and carry out ruling by annular token bucket.Data send scheduler and take out successively a plurality of package identifications from the head of annular token bucket, according to each sign, from the data queue to be given out a contract for a project of its corresponding shower nozzle, take out packet, in the packet header of each packet, add after upper nozzle sign, splicing copies in the continuous buffer memory of another piece of pre-first to file, then by driving, is mail to and is printed mainboard controller.Being sent in of a plurality of like this packets completes in once calling, and reduced the switching of application layer and inner nuclear layer, saves time.After this is sent completely, the package identification that previously head took out from annular token bucket is inserted into successively to the afterbody of annular token bucket, for recycling.
Data send scheduler circulation and read the sign in annular token bucket, take out to be sent to wait giving out a contract for a project print after mainboard controller from the outgoing queue of corresponding shower nozzle, outgoing data bag is become to inactive data bag and return to Buffer Pool.Printing equipment utilizes each shower nozzle relative position information to be converted into the print trigger amount of delay of each shower nozzle, makes each shower nozzle start in place the printing of every part.Method of the present invention can each shower nozzle of flexible configuration position, be specially adapted to the unconfined many nozzle printings system of each shower nozzle relative position.The printing equipment of the dynamic data of asynchronous many shower nozzles of the present invention can be divided into presentation layer and Business Logic function.
Printing equipment presentation layer provides visual edit interface for wanting printed matter, and handled easily personnel input space of a whole page content and parameter information.Specific implementation: program provides an independently make-up editor unit PHCanvas for each shower nozzle
jwith various print components, wherein j represents the sign of shower nozzle, 0=<j<MaxHeads, and MaxHeads is one and prints total shower nozzle number that mainboard controller is controlled; Print components comprises text component, serial number assembly, bar Code Element, time component etc.Make-up editor unit is the abstract of the actual printed matter of shower nozzle, and the drafting of every part of corresponding make-up editor unit of printed matter realizes.Make-up editor unit PHCanvas
jthe horizontal overall dimensions of size required covering of this shower nozzle in the longitudinal size of shower nozzle, every part of printed matter and the resolution of printing decide.Every kind of print components prints a type information piece PB on thing corresponding to reality.Print components is with the form tissue of occupy-place assembly and components values, occupy-place component package corresponding type information piece PB position, some attributes such as size, components values is the print What that operating personnel set, content can be made as and fixing also can be made as variablely, and variable data source can be tied to external data base or program produces.The actual print image of every part of printed matter is drawn after all component value of unified this shower nozzle of renewal in internal memory.In the present embodiment, a total shower nozzle of printing the control of mainboard controller is counted MaxHeads=4.
The Business Logic of printing equipment is that core realizes part, as shown in Figure 3, and its specific implementation following functions:
1 printing equipment initialization.Set up the cache pool PkgPool of inactive data packet pool.Program is from internal memory of system application when initialization, and being organized into size is the inactive data bag cache pool of M.The memory size of application is M*C, and C is the max cap. parameter of cache pool.And for each shower nozzle is set up independently outgoing data bag queue Q
j, and initialization Q
jfor empty queue.
2 annular token bucket initialization.Described annular token bucket, being embodied as element is the round-robin queue of package identification.The element value taking out from queue head just represents that corresponding shower nozzle obtains the quota of data transfer bandwidth.Meanwhile, Partial Elements reads out after use from the head, just no longer reenters in annular token bucket, and Partial Elements is still inserted into the afterbody of annular token bucket after reading out from the head use, thereby sends when scheduler is done the ruling that distributes bandwidth and recycle for data.The initialization of annular token bucket is in fact according to the relative position of each shower nozzle and spacing, defines initial period shower nozzle workspace PHWorkspace

ireturn to cache pool PkgPool.
In above-mentioned steps, parameter M, R chooses: consider the byte number K of the data volume that a spray printing of shower nozzle is required, stipulate that one is wrapped the line number R that can load, data package size M=(K*R+1).R is more than or equal to 1 integer.The value of R will be selected according to the value balance of actual K.Because M is larger, dynamic bandwidth regulates more inhomogeneous, and M is too little, also can cause the effective bandwidth of data to reduce.This embodiment be take Konica1024 as example, and this shower nozzle is 1024 nozzles altogether, thus K=128, as a kind of preferred version, R=3, M=385.
The benefit of this dynamic bandwidth allocation mechanism that the present invention proposes is, does not need inquiry to print the data consumes amount of each shower nozzle reality in mainboard controller, has saved communication time, and can also send more as required the data of each shower nozzle.And because annular token bucket only need be analyzed initialization once before starting printing, so can not affect the speed of print procedure.
In sum, the present invention does not lose the object that has realized efficiently nozzle position flexible configuration in the online print system of many shower nozzles.
Although be appreciated that embodiments of the invention only take one print mainboard controller and control 4 shower nozzles as example, also can revise a little under the occasion that applies to more shower nozzles.And if main frame has in the situation of a plurality of external interfaces, can also be expanded into a little the printing equipment of a plurality of printing mainboard controllers.
Be more than the specific embodiment of the dynamic data printing equipment of a kind of asynchronous many shower nozzles provided by the invention, just for helping to understand core concept of the present invention, this description should not be construed as restriction of the present invention; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, in embodiment and range of application, all can change to some extent part, these equivalent form of values fall within the limited range of the application's appended claims equally.
