|Title||Information technology -- Real-time locating systems (RTLS) -- Part 1: Application program interface (API)|
|Abstract||ISO/IEC 24730 defines two air interface protocols and a single application program 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 RTLS market. ISO/IEC 24730-1:2006, the RTLS API, establishes a technical standard for RTLS. To be fully compliant with this standard, RTLS must comply with ISO/IEC 24730-1:2006 and at least one air interface protocol defined in ISO/IEC 24730. RTLS 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 the physical properties of the radio link.
Conceptually there are four classifications of RTLS:
There are a further two methods of locating an object which are really RFID rather than RTLS:
The method of location is through identification and location, generally through multi-lateration. The different types are
ISO/IEC 24730-1:2006 defines an API needed for utilizing an RTLS.
An API is a boundary across which application software uses facilities of programming languages to invoke services. These facilities may include 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.
The information flow across the API boundary is defined by the syntax and 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 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 interface with the RTLS. This RTLS service is the minimum service that must be provided by an RTLS to be API compatible with this standard.
ISO/IEC 24730-1:2006 enables software applications to utilize an RTLS infrastructure to locate assets with RTLS transmitters attached to them. It defines a boundary across which application software uses facilities of programming languages to collect information contained in RTLS tag blinks received by the RTLS infrastructure.
