S6 —Technology of combining smart sensors and other IoT devices within one
wire network for monitoring of complex stationary and mobile objects: vehicles,
locomotives, smart homes, technological equipment etc. The technology is based
and expands SAE J1939 automotive standards.
Information on cabling system, service adapter and S6 software refer to
CAN j1939/S6 Operation manual.
CAN (Controller Area Network) —serial digital bus-type communication interface to comply
with ISO 11898-1:2003 International Standard.
Different high-level protocols can be used in the CAN bus to transmit data: J1939,
CANopen, DeviceNet, CAN Kingdom etc.
CAN bus is designed to unite various electronic executive units and sensors in the
automobile industry or industrial automation systems.
At present, the employment of CAN vehicle bus to receive data on the Vehicle in
GPS/GLONASS vehicle monitoring systems is of major interest.
FMS —Data packets of onboard vehicle data buses which comply with the
document “FMS-Standard Interface description” (FMS-Standard). FMS-Standard is
the open standard of the FMS interface designed by the world leading truck
producers.
A detailed description of FMS messages is contained in the document “FMS-Standard
Interface description” (FMS-Standard). The current version of the document can be
downloaded at the developing company site http://www.fms-standard.com.
OBD-II (On-board diagnostics) —the international standard of vehicle on-board diagnostics.
CAN and K-Line buses are used in the OBD-II to transmit data. Depending on the vehicle
manufacturer OBD-II employs protocols ISO 9141-2, ISO 14230 KWP 2000,
SAE J1850 VPW/PWM, ISO 15765-4 CAN.
OBD-II Standard provides access to parameters and codes of malfunctions of engine and
transmission control systems, enables to monitor the onboard computer data and carry out
diagnostics of the Vehicle onboard set of electronic control modules.
PGN (Parameter Group Number) —Is a combined group of S6 parameters, which has
common name and number. Functional modules (FM) of the Unit can have input/output
PGNs and setup PGNs.
SPN (Suspect Parameter Number) —Informational unit of S6. Each SPN has determined
name, number, extension, data type and numerical value. The following types of SPN exist:
Parameters, Counters, Events. SPN can have a qualifier which allows qualification of
parameter’s value (e.g. –Onboard power supply limit/Minimum).
Onboard equipment (OE) —Telematics system elements, directly installed in Vehicle.
