Electronic Logging Device Concept: Small Form-Factor ELD Based On Raspberry Pi With CAN Bus Port And GSM/GPRS/GNSS Support
An electronic logging device (ELD) is an electronic hardware that is attached to a commercial motor vehicle engine to record driving hours. The driving hours of commercial drivers (truck and bus drivers) are regulated by a set of rules known as the hours of service (HOS). The Commercial Vehicle Driver Hours of Service Regulations vary in Canada [...]
Easy Integration Of CANopen Or SAE J1939 Protocol Stack Into Any Embedded System With Serial Input
The simple assumption behind the statement of easy integration of a CANopen or SAE J1939 protocol stack is that virtually every embedded system (and even other industrial controls such as PLCs) do have a serial port of some sort, mostly UART, RS232, or USB. "Easy" also implies that you don't have to go through major [...]
Vehicle Tracking Device With CAN Bus Gateway Connects OBD-II Or SAE J1939 To Remote TCP Servers
Falcom (Germany) has introduced their Iobox-CAN, which connects to the Fox3-2G/3G/4G gateway via USB. The Fox3-2G/3G/4G gateway, in turn, links to a CAN Bus vehicle network (e.g., per OBDII interface) and reads the CAN Bus data and transmits it to a remote TCP server. The Iobox-CAN provides a second independent CAN Bus interface. It also comes with [...]
CAN Bus To Ethernet TCP/IP Gateway Also Supports Bridge Mode
The EtherCAN/2 by esd electronics is a hat-rail mounted gateway that exchanges data between CAN Bus and Ethernet networks. In bridge mode, two EtherCAN/2 modules can be used to connect two CAN Bus networks via TCP/IP.The unit comes with one Ethernet interface (10/100 Mbit/s, RJ45) and one CAN Bus high speed (ISO 11898-2) compatible interface (20 kBit/s up [...]
SAE J1939 Address Management Messages - Request For Address Claimed And Address Claimed
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. According to SAE J1939/81 network management procedures are used to “collectively manage the network”.In all consequence the network management is all about the Address Claim procedure and this procedure utilizes three messages and their PGNs:Request Message (PGN 59904)Address Claimed / Cannot Claim (PGN 60928)Cannot Claim Source Address [...]
Android Based In-Vehicle Tablet With SAE J1939 And CANopen Support
CP Device (China) introduced their series of displays suitable for road and off-road vehicles, which also support the ISO 15765-2 CAN transport protocol. The Chinese manufacturer offers different screen sizes, 7-inch or 10.1-inch. The devices utilize 1.5-MHz quad-core processors. The Apollo 10 display features 2-GiB RAM and 16-GiB ROM extendable to 32 GiB. There are several communication options [...]
CAN Bus USB Module With Two Isolated High-Speed CAN FD Interfaces
The CAN-USB/400-FD by esd electronics is a USB gateway module with two isolated CAN Fd ports compliant with ISO 11898-2. The module is powered by an ISO 16845:2004 certified esd Advanced CAN Core (esdACC) implemented in an Altera FPGA, and it is capable of managing of up to 100% CAN busload. The interface can transmit and receive [...]
SAE J1939 Network Management And Address Claim Procedure
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. According to SAE J1939/81, network management procedures are used to “collectively manage the network”. The chapters on network management have no logical structure (Again, explaining the function of an automobile, starting with the details of the fuel injection system); they explain the address claim messages first in [...]
