Page 3 prEN 3910-001 : 1996 O Introduction This standard contains requirements for an aircraft internal time division multiplex data bus for use in systems integr
9、ation of aircraft subsystems. The data bus consists of a STANAG 3838 (MIL-STD-1553B) controlled fibre optic or electrical interconnection channel for high speed data transmission. The control system is fully compatible with STANAG 3838 or its fibre optic equivalent. (In this document any reference t
10、o STANAG 3838 should be taken to mean either STANAG 3838 or its fibre optic equivalent). Even with the use of this standard, subtle differences will exist between data buses used on different aircraft due to particular aircraft mission requirements and the designer options allowed in this standard.
11、The system designer has to recognize this fact and design the bus controller hardware and software to accommodate such differences. These designer selected options has to exist, so as to allow the necessary flexibility in the design of specific multiplex systems in order to provide the control mecha
12、nism, architecture redundancy, degradation concept and traffic patterns peculiar to the specific aircraft mission requirements. The following document is structured to follow the organization of STANAG 3838 document as closely as possible. The high speed media characteristics are defined in parametr
13、ic terms in the body of the standard, with the numerical values corresponding to optional implementation configurations being given in the “HS Fibre Optic Media Slash Sheets“ (ANNEX B) or “HS Electrical Media Slash Sheet“ (ANNEX E). The main body of this document is identical to the final draft of S
14、TANAG 3910. 1 Scope This standard specifies the characteristics and requirements of a data bus system which consists of one or more High Speed (HS) Channel(s1 for HS data transmission and one Low Speed (LS) Channel for control and LS data transmission. The standard defines the HS fibre optic or HS e
15、lectrical data bus transmission line. The concept of operation and information flow on the HS multiplex data bus and the optical, electrical and functional formats to be employed are also defined. The electro-optical or electrical HS transmission and reception units which interface to the associated
16、 protocol electronics are described in EN 371 5. When invoked in a specification or statement of work, the requirements defined in this standard shall apply to the multiplex data bus and associated equipment which is developed either alone or as a portion of an aircraft system or subsystem developme
17、nt. Page 4 prEN 3910-001 : 1996 Four types of system are defined : Type A Low Speed Channel - STANAG 3838 data bus High Speed Channel - Fibre Optic data bus Type B Low Speed Channel High Speed Channel - Fibre Optic equivalent of STANAG 3838 - Physically separate Fibre Optic data bus data bus Type C
18、Low Speed Channel High Speed Channel - Fibre Optic equivalent of STANAG 3838 - Wavelength Division Multiplexed with the Low data bus Speed Channel onto a common fibre optic medium Type D Low Speed Channel - STANAG 3838 data bus High Speed Channel - Physically separate wire data bus The implementatio
19、n of a fibre optic medium for the HS Channel is given in Annexes A and B. The implementation of an electrical medium for the HS Channel is given in Annex E. The redundancy of individual LS and HS Channels is implementation specific. 2 Normative references This European Standard incorporates by dated
