1. Definitions
- SXL
Signal exchange list. Defines which messages types (signals) which is possible to send to a specific equipment or object. E.g. alarms, statuses and commands
- NTS
National Traffic management system. Replaces CTS
- Maximo
STA’s support system for maintenance
- ITS site
Road side equipment. Covers both field level and local level
- Site
See ITS site
- Local road side equipment
See ITS site
- Supervision system
Control and supervision system for regional and/or national level
- Object
An object is a abstract term which is used in control and supervision systems. An object can have on or more statuses that may change depending on changes of circumstance of the object or control of the object from external source. Communication with the object is made using exchange of signals, e.g. commands, status and alarms.
An object can represent physical equipment or abstract concepts E.g. a camera, a control flow alorithm or a group of signs.
An object is identified using the objects component id. Please note that an object is not necessarily the same thing as an NTS object.
- Aggregated object
An aggregated object consists of one or many other objects. E.g. Component group (CG)
- Object type
An object type is a classification of objects that controls the properties of all the objects of the same object type. The object type determines how the object is presented in supervision system, how it is grouped and which functional positions, alarm codes, commands and statuses that exists that object type.
- NTS Object
Used for objects in NTS
All control and supervision related functions in NTS consist of NTS objects.
An NTS object can represent on or many objects.
An NTS objects is identified in the communication interface using “externalNtsId”. NTS can not use the format used in component-id.
An object and NTS object and use the same component-id.
- NTS-Object type
A NTS object type is a classification of NTS objects. Determines among other things which functional positions that are possible for the NTS object.
- Component
A component is a object or NTS object.
A component is identified using component-id.
- Component-ID
A component-id identifies components.
The format used for the STA’s sites is specified in the STA publication TDOK 2012:1171, e.g. AA+BBCDD=EEEFFGGG.
