20、bsystem of postal automation equipment. One related standard is CEN/TS 15448, Postal Services Open Standard Interface between image controller and enrichment devices (OCRs, video coding systems, voting systems). Other work items (subject to agreement of CEN/TC 331 and the UPU Standards Board) will b
21、e defined to cover other areas as and when the need is identified and the resources for development become available. A separate project group for each interface will undertake the work. DD CEN/TS 16238:2011CEN/TS 16238:2011 (E) 6 1 Scope This Technical Specification describes the “Open Standard Int
22、erface between Image Processor, Machine Control and Image Controller” (IP/MC/IC Interface) in the context of postal automation equipment. The following architectural overview is the basis for this interface standardization: Figure 1 System overview It was agreed to unify the interfaces between a) Im
23、age Processor and Image Controller, b) Image Processor and Machine Control and c) Machine Control and Image Controller and to produce one common specification for this so-called IP/MC/IC Interface. The communication partners of this interface will be called Machine or Machine Control (MC) on the one
24、 side and Reading/Coding (RC) System on the other side. There may be several instances of this interface, depending on the implementation of the MC and the connected RC. NOTE interfaces for synchronizing the lifted images with their mailpiece_IDs provided by the machine are not shown in the figure a
25、bove and are not subject of standardization within the first release of this interface. From the customer point of view, the following two scenarios are relevant. The systems MACHINE and RC SYSTEM are to be considered as “black boxes” thus not detailing internal system structure and interfaces. 1) T
26、he Machine already includes Camera and Image Processor and will be connected to a 3rd-party RC System including Image Controller and Enrichment Devices. DD CEN/TS 16238:2011CEN/TS 16238:2011 (E) 7 Figure 2 System interfacing scenario 1 2) The Machine will be connected to a 3rd-party RC System includ
27、ing Camera, Image Processor, Image Controller and Enrichment Devices. The Camera and (possibly) the Image Processor will have to be mechanically integrated into the machine. NOTE The camera can be provided by any 3rd-party. This should not impede on the IP/MC/IC interfaces ! Figure 3 System interfac
28、ing scenario 2 DD CEN/TS 16238:2011CEN/TS 16238:2011 (E) 8 This standard is arranged under four main clauses as described in Figure 4. UCM (Use Case Model) describes the use cases for the IP/MC/IC Interface using sequence diagrams with messages. IDD (Interface Design Description) defines the data mo
29、del for the IP/MC/IC interface. SDD (System Design Description) defines the mandatory specification of the IP/MC/IC interface in terms of architecture, services and behavioural models. In the Common Part of this clause no middleware or transport layer is specified. The common part of this clause is
30、intended to be middleware-independent. SDD-TCP/IP, SDD-CORBA, SDD-SOAP in these specialized clauses. The specifications for three compatible transport solutions TCP/IP, CORBA and SOAP are provided. Further middleware solutions can be added when available, provided that they are fully compatible with
31、 the Common Part. Figure 4 IP/MC/IC Interface Document Structure 2 Normative References The following referenced documents are indispensable for the application of this document.
