4 Introduction This protocol is meant to be used for data acquisition in fleet management applications in the field of municipal vehicles. The purpose of the protocol is to define how data of a vehicle or equipment is generated, stored and transferred to a board-computer system in the vehicle and from the board-computer to the software application in the office (refer to Figure 1). On the equipment or vehicle the data is generated by a “Data generator”. This data is stored, if present, into a buffer-memory. The “Data transmission handler” will send the data present in the buffer-memory to the “Board-computer” or “Data Acquisition System”. The buffer-memory is there to ensure that data does not get lost in case there is no transmission possible. The size or type of the buffer is not defined in this proposal. If there is no buffer or the buffer is too small to store new data, data will get lost. To synchronise time-stamps of the vehicle/equipment with the Board-computer, a special record for time synchronisation is defined. In this part the data acquisition and communication from vehicle/equipment to the Board-computer is defined.
Figure 1 – Architecture
In general, the data is a semi-colon (“;”) separated ASCII text for separation of record codes and values of variables. CR+LF is used for separation of records (one record is one line of text).

6 1 Scope This European Standard specifies a standardized protocol for downloading data from the equipment control box to an in-vehicle board computer to ensure interchangeability between a vehicle and different equipments that the same vehicle can carry. It specifies the interface connection as well as variables, records and reports which permit standardized protocol to cover applications with the greatest possible variety of equipments for performing winter maintenance and road service area maintenance. 2 Normative references !The following referenced documents are indispensable for the application of this document.

4.2.3 Communication protocol ! Transmission of a record. In this definition a message to be communicated consists of one record. Records are terminated by CR+LF (a record is one line of text). In general, a message is sent by the sender (e.g. the “Data transmission handler” of a spreader) and received by the receiver (e.g. the Board-computer). After power up, communication is always started by the vehicle/equipment “Data transmission handler” sending its first message (this is the time synchronisation record). Refer to Figure 4 for flow charts of the sender and receiver algorithms. The receiver will check the validity of a message by testing if the CRC-16 value corresponds to the data in the message received. If the data is valid, the receiver sends an ACK. The sender can now send a new message. If the data is invalid, the receiver sends a NAK. Then, the sender will try to send the same message again for a maximum of 2 times. If the message still fails, the message is considered to be lost. Preferably, a notification is given to the user (operator) that data has been lost by the sender and/or the receiver. NOTE 1 The receiver sends an ACK or a NAK as a single character without other data. The ACK or NAK refers to the latest message sent by the sender. To avoid record synchronisation problems between sender and receiver, the sender must ignore any ACK or NAK received during the transmission of a message until the last byte is sent (EOT character). Also, the receiver is not allowed to send an ACK or NAK during the reception of a message until the last byte is received (EOT character). NOTE 2 Numerical values have to be transmitted with ASCII characters in decimal code. Calculation of the CRC-16 value. The CRC value is calculated according to the CCITT definition. The CRC value is calculated over all record bytes, starting with the record code, ending with CR+LF. The polynomial used is x16 + x12 + x5 + x0 = 11021h (i.e. XOR mask 1021 h) and initial value FFFFh. NOTE 3 The value is written in ASCII characters in hexadecimal code with capitals (0.9,A.F). Calculation of the CRC-32 value. The CRC-32 value is calculated according to the CCITT definition. The CRC-32 value is calculated over all record bytes, starting with the record code, ending with CR+LF. The polynomial used is x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1
NOTE 4 The value is written in ASCII characters in hexadecimal code with capitals (0.9,A.F). Sender without receiving options for handshaking. For old vehicle/equipment “Data transmission handlers”, it may be impossible to receive data. In this case the sender cannot respond to an ACK or NAK, i.e. there is no handshaking feature. Hence, the sender will send a new message. This may cause in the result that data gets lost, e.g. in case the Board-computer was not started up yet SIST EN 15430-1:2008+A1:2011

12 5 Definitions of variables, records and report 5.1 General A report is a file of records which in general is used to describe one ride. A report starts with a header record, one or more status records of the vehicle/equipment(s) and a footer record. A record is a structure of coherent variables in a predefined order. A member of a record is called a “field”. Table 1 - Application or equipment types Equipment Source ref.nr.RemarkBoard computer 1
Vehicle 2 On board vehicle electronic generating data Snow plough or broom 3 It is assumed that if there is more than one snow-plough, the data is generated by one source only. Snow blower or cutter 4
Spreader or sprayer 5 Remark: this equipment could also generate the data for example for a snow plough, however, the source reference number stays 5 (as the spreader is the data generator). Road weather and road condition information system 6
Grass or branch cutting machine 7
Sweeper 8
Safety post cleaning machine 9
Boat plants cutter 10 Used for cutting plants in canals or rivers Other 11 To be used for any equipment not defined ! 5.2 Data integrity check There are at least two methods required to assure integrity: a) Data have to be checked for manipulation of the contents themselves. b) Data have to be checked for completeness: Data have to be checked against any deletion of any parts of them. In the present standard these two requirements lead to the following methods of covering: - Data manipulation (a) is checked by CRC. - Data deletion (b) is checked by including the previously calculated CRC value into the new CRC value.

The predefined string length has to be covered completely with valid characters.
• If the valid string content is shorter than the predefined length ( X characters), the rest of the predefined length has to be filled with FFh characters to indicate that these characters are not valid. • If a transmission handler cannot supply the string filed the first character has to be either 00h, when the contents are incorrect, or FFh, when the contents are not available. In these two special cases the string length may be only one character in size, although it is also allowed to fill the rest of the predefined string length with FFh characters.

This permits data consistency is to be maintained as much as possible between parameters of a given type (temperature, pressure, speed, etc.). Each SLOT is intended to provide a range and resolution suitable for most parameters within a given type. When necessary, a different scaling factor or offset can be used. All SLOTs should be based on a power of 2 scaling from another SLOT. This will minimize the math required for any internal scaling and reduce the opportunity for misinterpreted values. Offsets should be selected preferably on the following basis: SIST EN 15430-1:2008+A1:2011

General variables apply to non application specific variables. Some application specific variables may be generated by other applications (e.g. spreader generates plough data and/or road weather information as well). If a variable is a field of a record being generated, then its value at the moment of generation is written as defined by the basic type format in 5.3 or the SLOT definition in 5.4. The following variables are defined: SIST EN 15430-1:2008+A1:2011
