1. Definitions
- Alarm code id
Identity of an alarm
The examples in this document are defined according to the following format: Ayyyy, where yyyy is a unique number.
- Command code id
Identity of a command
The examples in this document are defined according to the following format: Myyyy where yyyy is a unique number.
- External alarm code id
Manufacturer specific alarm code and alarm description. Includes manufacturer, model, internal alarm code och additional alarm description.
- External NTS alarm code id
Alarm code in order to identify alarm type during communication with NTS
- Aggregated object
An aggregated object consists of one or many other objects. E.g. Component group (CG)
- Component
A component is an object or NTS object.
A component is identified using component id.
- Component id
Identity of a component
The format used for the STA’s sites is specified in the STA publication TDOK 2012:1171, e.g. AA+BBCDD=EEEFFGGG.
- DATEX II
European standard for message exchange between traffic systems (www.datex2.eu)
- Functional position
Provides command options for a site. For instance, “start” or “stop” It is meant to be used for the entire site and not for an individual component. It can be implemented using a command and can be read from the site using the aggregated status message.
- Functional state
Not used
- ITS site
Road side equipment. Covers both field level and local level
- JSON
JavaScript Object Notation
- Local road side equipment
See ITS site
- Maneuver
Provides command options for one or many individual components. For instance, “start” or “stop”. It can be implemented using a command and can be read from the site using a corresponding status message.
Designed to be used with NTS.
- Maximo
STA’s support system for maintenance
- NTS
National Traffic management system at the STA.
- NTS object
Used for objects in NTS
All control and supervision related functions in NTS consist of NTS objects.
An NTS object can represent one or many objects.
- External NTS id
Identitiy for an NTS object used in communication between NTS and other systems
The format is 5 integers and is unique for the site. It is defined in cooperation with representatives from NTS.
- 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.
- Object
An object is a abstract term which is used in control and supervision systems. An object can have one 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 algorithm or a group of signs.
An object is identified using component id. Please note that an object is not necessarily the same thing as an NTS object.
- 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 for that object type.
- Parameter
Used for modification of technical or autonomous traffic parameters of the equipment. Can be implemented using commands and statuses.
- RSMP
Road Side Message Protocol
- RSMP Nordic
Organization for maintaining and develop the RSMP protocol. Collaboration between a group of Nordic road authorities.
- Site
See ITS site
- Site id
Site identity. Used in order to refer to a “logical” identity of a site.
At the STA, the following formats can be used:
The site id from the STAs component id standard TDOK 2012:1171 e.g. ”40100”
It is also possible to use the full component id (TDOK 2012:1171) of the grouped object in the site in case the site id part of the component id is insufficient in order to uniquely identify a site.
- STA
Swedish Transport Administration
- Supervision system
Control and supervision system for regional and/or national level
- 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
- Status code id
Identitiy for a status
The examples in this document are defined according to the following format: Syyyy where yyyy is a unique number.
- TCP/IP
Transfer Control Protocol/Internet Protocol
- W3C
World Wide Web Consortium
- XML
