This Technical Specification (CEN/TS) was approved by CEN on 14 February 2012 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

Foreword
This document (CEN/TS 15430-2:2012) has been prepared by Technical Committee CEN/TC 337 “Winter
maintenance and road service area maintenance equipment”, the secretariat of which is held by AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This European Standard is one of the series CEN/TS 15430 "Winter and road service area maintenance
equipment - Data acquisition and transmission" which consists of the following parts:
 Part 1: In vehicle data acquisition
 Part 2: Protocol for data transfer between information supplier and client application server
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Introduction
This Technical Specification is the second part of EN 15430, the standard for data acquisition and
transmission in the field of municipal vehicles. The goal of EN 15430 is to allow interoperability between
systems (hardware and software) of different vendors. A customer should be able to combine
 any on-vehicle equipment (e.g. spreaders and ploughs),
 any on-vehicle data acquisition systems (e.g. board computers or enhanced control boxes),
 any client application software (e.g. data bases, analysing or accounting software),
as long as they follow EN 15430.
EN 15430-1:2007+A1:2011 defines the on-board communication (flow 1) between on-vehicle equipment (data
handler) and on-vehicle data acquisition systems (board computer). This document is meant to describe the
data structure, types, ranges, protocol and initial settings required by the information supplier server (ISS) and
client application server (CAS) including synchronized combining of the various data sources.
Figure 1 represents the whole data flow chain from vehicle to office system.

Figure 1 — Transmission flow
Data that are collected are operating data of the vehicles, which contain time information, geo reference data
and machine status data. These data are stored in different memories: on the vehicle, in the facility where the
vehicles are maintained and in office, where data are retrieved and analyzed. Due to the fact that the collected
data can be used not only to supervise work contents and results, but also as proof in case of accidents, the
integrity and the correctness of the data are important and indispensable. The present Technical Specification
contains seamless integration of mechanisms into the data flow starting at the data sources and ending at
data analysis on the client application server (CAS).
The present Technical Specification does not define any specific rules for items like
 optional compression, encryption and authentication of the data during data transfer (flow 2),
 data transmission between on-vehicle data acquisition system and information supplier server (flow 2).
Data transfer between on-vehicle data acquisition systems and the information supplier server has to be
lossless, this means that reduction of data is not allowed. Lossy compression methods are not allowed.
In Figure 1, Section 1 defines the interface between devices and board computer, as described in
EN 15430-1:2007+A1:2011. Section 2 addresses the combination of data from different streams and the
transmission to a generic information supplier server. Section 3 addresses the data transfer (flow 3) between
the information supplier server (ISS) and client application server (CAS) and it is the purpose of this
document.
1 Scope
The function of this Technical Specification is to combine any vehicle equipment with different board
computers to any client application server. The communication interface on vehicle is defined by
EN 15430-1:2007+A1:2011. The interface between the information supplier server and the client application
server is defined as a specific protocol (flow 3), object of the present Technical Specification. This makes
interchangeability possible on both sides of the communication without any restriction in the range of
communication technology including memory card, WLAN, GPRS or any other communication media.

5 Tasks of the board computer
5.1 Classification
In EN 15430-1:2007+A1:2011, a data acquisition system like a board computer has been presented as a
black box with at least the following main features implemented:
 receive data from a generic vehicle/equipment data transmission handler (e.g. through RS232 serial
interface);
 store any incoming information in reports;
 generate one time stamp for every data message.
According to the time gap between record time stamp and ISS time stamp
