14、 particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have

22、1:2014(E)IntroductionISO/IEC 24730 defines several air interface protocols and a single Application Programming Interface (API) for Real Time Locating Systems (RTLS) for use in asset management and is intended to allow for compatibility and to encourage interoperability of products for the growing R
23、TLS market.This part of ISO/IEC 24730, the RTLS Application Programming Interface, establishes a technical standard for Real Time Locating Systems. To be fully compliant with ISO/IEC 24730, Real Time Locating Systems (RTLS) shall comply with this part of ISO/IEC 24730 and at least one air interface
24、protocol defined in ISO/IEC 24730.Real Time Locating Systems are wireless systems with the ability to locate the position of an item anywhere in a defined space (local/campus, wide area/regional, global) at a point in time that is, or is close to, real time. Position is derived by measurements of th
25、e physical properties of the radio link.Conceptually there are four classifications of RTLS: Locating an asset via satellite - requires line-of-sight - accuracy to 10 meters Locating an asset in a controlled area, e.g., warehouse, campus, airport - area of interest is instrumented - accuracy to 3 me
26、ters Locating an asset in a more confined area - area of interest is instrumented - accuracy to tens of centimetres Locating an asset over a terrestrial area using terrestrial mounted receivers over a wide area, cell phone towers for example accuracy 200 metersWith a further two methods of locating
27、an object which are really RFID rather than RTLS: Locating an asset by virtue of the fact that the asset has passed point A at a certain time and has not passed point B Locating an asset by virtue of providing a homing signal whereby a person with a handheld can find an assetMethod of location is th
28、rough identification and location, generally through multi-lateration, of various types Time of Flight Ranging Systems Amplitude Triangulation Time Difference of Arrival (TDOA) Cellular Triangulation Satellite Multi-lateration Angle of ArrivalThe location information of an asset may further be enhan
29、ced with information on its spatial orientation.This part of ISO/IEC 24730 defines an application programming interface (API) needed for utilizing an RTLS system.An API is a boundary across which application software uses facilities of programming languages to invoke services. These facilities may i
30、nclude procedures or operations, shared data objects and resolution of identifiers. A wide range of services may be required at an API to support applications. Different methods may be appropriate for documenting API specifications for different types of services. ISO/IEC 2014 All rights reserved vC

32、 semantics of a particular programming language, such that the user of that language may access the services provided by the application platform on the other side of the boundary. This implies the specification of a mapping of the functions being made available by the application platform into the
33、syntax and semantics of the programming language. An API specification documents a service and/or service access method that is available at an interface between the application and an application platform.This API describes the RTLS service and its access methods, to enable client applications to i
34、nterface with the RTLS system. This RTLS service is the minimum service that shall be provided by a RTLS system to be API compatible with this standard.This part of ISO/IEC 24730 uses a “full stop” as the decimal point separator since an API file is being created with an output in a .csv file format
35、 which uses the comma to separate values.vi ISO/IEC 2014 All rights reservedCopyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS ISO/IEC 24730-1:2014INTERNATIONAL STAND

It defines a
