Port arrangement is shone upon subelement 351, also is used to detect and store the state of each print head port, and reports notification message by printing machine interface unit 34, host interface unit 33 to configuration information generation unit 32, carries available print head port information;
The state of port arrangement mapping subelement 351 each print head port of storage can provide basis for judging look face port configuration information;
Configuration information generation unit 32 also is used for the print head port information that can use according to the printing machine of notification message updated stored unit 31 storages that receive.
The digital printing equipment that the embodiment of the invention provides, the print head port number that is provided with on the printing machine is greater than the look face quantity of its support, and when handling operation to be printed each time, look surface information according to available print head port information and operation to be printed dynamically generates look face port configuration information, it is the corresponding relation of look Noodles type and print head port, make transfer of data can not be subjected to occurring in the digital printing equipment influence of the print head port of hardware fault, if certain print head port breaks down in current operation processing procedure to be printed, can be by reconfiguring look face port configuration information, aspect, solve the hardware fault problem of print head port efficiently.
Below, to according to the look surface information of operation to be printed and printing machine can with the print head port information generate look face port configuration information and carry out brief analysis.
The look face quantity of supposing operation to be printed is cnum (cnum 〉=1), and printing machine can with the print head port number be N (N 〉=cnum), so following relation will be arranged:
When N=cnum, generate the look face port configuration information between N port and N the look face, total
Plant allocation plan;
Describe with example one, the print head port numbers is 1,2,3,4, the look Noodles type of operation to be printed is K, C, M, Y, the corresponding relation between then configurable available print head port numbers 1,2,3,4 and look Noodles type K, C, M, the Y, for example 1,2,3,4 corresponding K, C, M, Y; Perhaps corresponding M, C, K, Y, or the like, altogether 4!=24 kinds of allocation plans.
As N〉during cnum, generate the look face port configuration information between N port and cnum the look face, total
Plant allocation plan;
Describe with example two, the print head port numbers is 1,2,3,4,5, the look Noodles type of operation to be printed is K, C, M, Y, corresponding relation between then configurable available print head port numbers 1,2,3,4,5 and look Noodles type K, C, M, the Y, for example 2,3,4,5 corresponding M, C, K, Y, perhaps 1,2,3,5 corresponding K, C, M, Y, or the like, 5! altogether=120 kinds of allocation plans.
Suppose and have the print head port hardware fault to occur that the print head port quantity that breaks down is enum, then as N-enum 〉=during cnum, generate the look face port configuration information between N-enum port and cnum the look face, total
Plant allocation plan;
Suppose to have disposed in the example two 1,2,3,5 corresponding K, C, M, Y, fault has appearred and the print head port numbers is 3 print head port, then reconfigurable, print head port numbers 3 is deleted from available print head port numbers, corresponding relation between print head port numbers 1,2,4,5 that the configuration residue is available and look Noodles type M, C, K, the Y, for example 1,2,4,5 corresponding K, C, M, Y.
Based on same technical conceive, the embodiment of the invention provides a kind of data transmission method of digital printing equipment, as shown in Figure 4, comprising:
The print head port information that S401, main frame can use according to the printing machine of the look surface information of operation to be printed and storage, generate the look face port configuration information of operation to be printed, and of all kinds data of look face port configuration information and operation to be printed are sent to printing machine;
S402, printing machine be according to the look face port configuration information that receives, of all kinds data of operation to be printed sent on the corresponding print head port, wherein, the look face quantity that the print head port number that is provided with on the printing machine is supported greater than digital printing equipment;
Of all kinds data of look face port configuration information and operation to be printed are transmitted by different passages between main frame and printing machine.
Preferable, printing machine detects and stores the state of each print head port, and report notification message to main frame, carry available print head port information, notification message is reported according to calling time in the configuration by printing machine or periodically reports or report when the state that detects the print head port changes according to the time interval of setting; The print head port information that main frame can be used according to the printing machine of the notification message updated stored that receives.
Be example with the digital printing equipment of supporting K, C, M, four kinds of look Noodles of Y type below, the transfer of data flow process of digital printing equipment is described, wherein for the print head port number of digital printing equipment setting be N, N is greater than four, and the look surface information of supposing current operation to be printed comprises that look face quantity is four, look Noodles type is K, C, M, Y, and then as shown in Figure 5, the transfer of data flow process comprises:
S501, main frame generate of all kinds data of operation to be printed, i.e. K, C, M, four kinds of look faces of Y data;
S502, main frame are judged the print head port number whether the look face quantity of operation to be printed can be used smaller or equal to the printing machine of this locality storage, whether enough available print head port are promptly arranged, if then carry out S503; If not, then break down can't operate as normal for digital printing equipment, and flow process finishes;
S503, main frame are the unique print head port numbers of each look Noodles type configuration;
S504, main frame generate look face port configuration information according to the look Noodles type of configuration and the corresponding relation of print head port numbers, and of all kinds data of look face port configuration information and operation to be printed are sent to printing machine;
S505, printing machine judge whether each the print head port in the look face port configuration information is current available, if, then carry out S506, if not, then carry out S511;
S506, printing machine are according to the mapping relations between look face port configuration information configuration print head port numbers and the look Noodles type;
S507, printing machine be according to the mapping relations of configuration, and the look face data of each type in the operation to be printed are sent on the print head port of corresponding print head port numbers indication;
S508, printing machine detect current each print head port that is using in the current operation process to be printed of printing, judge whether to occur the print head port of fault, if, then carry out S509, if not, then until being completed for printing, flow process finishes;
S509, printing machine are then ended current operation to be printed, and return second prompting message that port breaks down to main frame, carry the current print head port numbers that breaks down;
S510, main frame are according to second prompting message that receives, the printing machine of storage can with the print head port information in the print head port numbers that will be current breaks down delete, and the look face port configuration information that regenerates operation to be printed sends to printing machine, continuation execution S505;
