Embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is described in detail.
The invention provides a kind of substation equipment Method of printing and system of printing terminal Network Based, described substation equipment and network printing terminal access transformer station's communication network simultaneously, are realized the flexible printout of substation equipment by the data interaction between network agent module.Print system provided by the present invention is made up of substation equipment subsystem and network printing terminal subsystem, and both all access transformer station's communication network; Described substation equipment subsystem is print data provider, and network printing terminal subsystem is print data output side, and transformer station's communication network is print data transmission medium; Described substation equipment subsystem configures print management module, local printing output module and home network proxy module; Described network printing terminal subsystem need configure distant place network agent module, distant place printout module and distant place printing control model;
The Print Control order in the local or distant place of described print management resume module, to integrate and the print data of encapsulation format, and with local printing output module or home network proxy module interactive command and data message;
Described local printing output module receives the local printing function of the data out message finishing equipment of print management module;
Described home network proxy module and the realization of distant place network agent module print data to the mapping of network communication protocol and transmit data by communication network in station;
After described distant place printout module receives print command and data content from distant place network agent module, realize format print after performing data processing or conversion operations again and export;
Described distant place printing control model passes through the long-range setting of transformer station's communication network and the printing function of opertaing device.
As shown in Figure 1, of the present inventionly realize configuration diagram, substation equipment is divided into print management module, local printing output module, home network proxy module according to function, print management module realizes print command process, print data integrates the functions such as encapsulation, information interaction can be carried out with home network proxy module and realize distant place printout, also directly can realize local printing function by local printing output module simultaneously.Network printing terminal comprises distant place network agent module, distant place printout module and distant place printing control model, distant place network agent module receives from the data of substation equipment network agent module and command information and is passed to printout module, printout module in a distant place again according to terminal configuration and control command process print data, and realizes print data and exports in the information of different medium interface.And distant place printing control model can pass through the long-range setting of communication network in station and the printing function of opertaing device.
The realization flow of overall printing function as shown in Figure 2, will be introduced below respectively.
When transformer station adopts ethernet communication, first substation equipment and the network agent module of network printing terminal need to set up TCP by ether communication network and link transport vehicle as print data and order.After equipment receives the concrete print command in this locality or a distant place, its print management module in charge is resolved print parameters and is compiled relevant print data information, then print data, format information and control command are packaged into data block and pass to home network proxy module, the latter sends to the distant place network agent module of network printing terminal after adding Ethernet TCP Communication Control information.Distant place network agent module peels off Ethernet TCP Communication Control information and the type information data block of reduction apparatus pass to printout resume module.Printout module is resolved and print data of recombinating according to the format information of data block, and selects output interface according to terminal configuration and control command and perform printout operation.When other similar communication networks of application in substations, the communications protocol realizing similar ethernet communication process by network agent module maps or reduction work.
The mode of operation that two kinds different can be selected in the substation equipment Method of printing practice of printing terminal Network Based.The first mode of operation is centered by substation equipment, and network printing terminal plays the part of subordinate role.Substation equipment initiatively sets up the communication contact with network printing terminal according to demand, and the debugging utilizing the latter to realize type information exports or expands the printer supporting new interface type.The second mode of operation is centered by network printing terminal, and substation equipment plays the part of subordinate role.Network printing terminal sets up communication contact from different substation equipments respectively by user's request, the printing of distant place starting outfit, realizes the concentrated print management demand of substation equipment information.Because substation equipment and network printing terminal are communication node in station, therefore both are not limited only to set up single annexation to list, can need the annexation setting up one-to-many, many-one, even multi-to-multi according to practical application.Multi-linkly only need the Portable Batch System considering multiple print job compared with single connection, the processing procedure of each print out task and single connection are applied does not have difference.
Network printing terminal in this method can be independently software entity, may also be the assembly of the arbitrary system software of transformer station.Terminal can set different printout patterns according to the actual requirements flexibly, both can select the virtual output forms such as man-machine terminal display, computer documents, also can realize the physical mediums such as pin type serial printer, the network printer and export demand.When substation equipment needs to increase the support to new interface printer, the program function of equipment need not be revised, only can need meet the demands at the driver module of network printing terminal increase new interface, and newly-increased interface have no effect to the original printing function of equipment.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, and every technological thought proposed according to the present invention, any change that technical scheme basis is done, all falls within scope.
