IEEE 1477-1998 pdf download IEEE Standard for Passenger Information System for Rail Transit Vehicles
This standard is divided into four clauses, C lause 1 provides the soope of this standard, C lause 2 lists references toother standardls that are usefil in applying this standard.C lause 3 provides defin itions for techn ical term s ueed in thiestandardl.C lauee 4 estab lishes interace standards for four subsysteam s w ith in the paseenger in fom ation systen of railtansitvehicles.
1.1 Scope
This standard app lies to extenal and intenal audiovisual com m unication of passenger infom ation, destination/upin fom ation, and announcem ents related to safety and em egencies, as w ell as advertisem ent/com m un ity infomm ationfor rail tansit vehicles, It specifies the physical, logical, and electrcal interfaces of the paseenger in foim ation systenfor rail transit vehicle system s and subsystem s. This includes the follow ing equ pm ent: passenger in form ation signs,pub lic address system , pasenger/crew call intercom syste , intenal diso lay system , and radio system interface w iththe public address system .
1.2 Purpose
The purpose of the standad is to estab lish the m inin um interface requirem ents forpassenger inform ation system s inorder to enable product interchangeability and com ponent com m onality.
1.3Application
his standard is intended to be used n soecitications forthe procure ent of ne railpaseenger vehic es (lnht, heavyand/or com m uter rail vehicles) , t is also intended to be used, as applicab le, in specificatlons for rehab ilitating orretrofitting existing ailpassengervehicles and for replacem ent system s.
This is an interface standard that defines vehicle paseenger infomm ation inteaces but is not intended to specily anym nm um num berofrequired passenger nfom ation features.
The cunent standard covers electrical and physical interfaces, Logical interfaces w ill be addreseed in a future draftEEE Standard forT ransit C om unications Interface Profiles for R ailA pplications.
2.References
This standard shall be used in con junction w th the follow ing publications, If the follow ing publications aesuperseded by an approved revision, the revision shall apply, In case of a conflict betw een this standad and thereferenoed docum ent, this standad shall take precedence, Those provisions of the referenced docum ents that are notin conflictw ith this standard shall apply as referenoed.
