PD CEN/TS 15430-2:2012CEN/TS 15430-2:2012 (E) 4 Introduction This Technical Specification is the second part of EN 15430, the standard for data acquisition and transmiss
19、ion 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 comp
20、uters 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 syst
21、ems (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

23、2:2012CEN/TS 15430-2:2012 (E) 5 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
24、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 se
25、amless 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 d
26、uring 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. Los
27、sy 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
28、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. PD CEN/TS 15430-2:2012CEN/TS 15430-2:2012 (E) 6 1 Scope The function of this Technical Specification is to combine any vehicle equipment wi
29、th 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 Techn
30、ical 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. 2 Normative references The following documents, in whole or in part, are

37、 data transmission handler (e.g. through RS232 serial interface); store any incoming information in reports; generate one time stamp for every data message. PD CEN/TS 15430-2:2012CEN/TS 15430-2:2012 (E) 8 According to the time gap between record time stamp and ISS time stamp one board computer can b
38、e 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: devic
39、es 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. 5.2 Data receiving and merging According to EN 15430-1:2007+A1:2011, the board computer receives data from one or more devi
40、ce handlers. In addition, it can generate records, e.g. by receiving GPS data, evaluating sensors or by converting non-standard data sources (described in EN 15430-1:2007+A1:2011). Then, the board computer merges the data flow from different devices into one data stream without applying and modifica
41、tion to the records (record code 1). All records should remain in the same order in which they were generated. The order of records coming from different sources is free. The delay probably introduced by the data transmission handler can be ignored. 5.3 Time information handling Time information rec
42、eived from board computers is stored on the ISS without any modification. The ISS has to add its local time information to the data files. 6 Classification, designation and coding 6.1 Report interface 6.1.1 Data record definition A data record is a structure of coherent variables in a predefined ord
43、er according to the record definition (EN 15430-1:2007+A1:2011). 6.1.2 Interface level The present Technical Specification defines a XML file structure containing one or more records as described in EN 15430-1:2007+A1:2011. The XML file has to be provided by the information supplier server (ISS). Th
44、e present Technical Specification sets forth that a board computer or a fleet management manufacturer has to provide a suitable information supplier server to ensure the XML file structure described in 6.3. PD CEN/TS 15430-2:2012CEN/TS 15430-2:2012 (E) 9 The definition of the XML file contents is: b
