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.

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 one board computer can be
classified as follows:
a) on-line devices: devices where the time gap between generation at the board computer and acquisition
by the ISS is within 60 s. (e.g.: radio, GPRS, UMTS). The ISS has to provide an on-line status information
to the CAS for every connected device;
b) off-line device: devices where the time gap between generation at the board computer and acquisition by
the ISS is 60 s or more.
Every board computer has to ensure 24 h of non-volatile data storage.
