J1939 Protocol Stack

J1939 Protocol Stack

iWave has implemented the J1939 Protocol Stack based on the SAE J1939 protocol. The SAE J1939 protocol communicates over the high-speed ISO 11898-1 CAN (HS-CAN) network. The iWave J1939 stack is designed to be used in heavy-duty environments and suitable for horizontally integrated vehicle industries but is also applicable for light-duty, medium-duty, and heavy-duty vehicles used on-road and off-road. The J1939 protocol also finds use in industrial diesel engines. The iWave J1939 protocol stack is designed to be platform and OS independent and can be easily ported for any end application.

 TELEMATICS AND VEHICLE ANALYTICS WITH J1939 PROTOCOL STACK

Heavy Duty Vehicles

Fleet Management

 Waste Management Truck

Telematics Gateway for Heavy Duty Vehicles
Heavy duty vehicles are used for long hours in extreme working conditions, it is important for the owners to monitor as they are vulnerable to sudden failures and frequent breakdowns as they are used in rough environmental and operating conditions. With Telematics Device and J1939 Protocol support, we can help reduce this risk, it has built-in interfaces like 4 CAN ports, RS232, RS485 and rugged IP enclosure to support the smart functions like accident report, theft alarm, live tracking, route planning and driving analysis.
Vehicles are leased out by manufacturers for various use cases, it is important for the owners to monitor their location and the parameters to effectively control the usage. Telematics device along with fleet management system integrated with J1939 protocol stack can act as a fleet tracker to determine live location updates and road conditions. With this data, fleet managers can take preventive maintenance thereby reducing unnecessary fuel wastage, delays and cost.
Waste management trucks should run well-organized productive fleets. With Telematics gateway fleet management solutions, owners and fleet managers can get access to the key vehicle parameters through J1939 Protocol stack such as vehicle’s location, speed, direction, fuel efficiency, emission levels and calibrate the vehicle’s performance and efficiency. It also provides drivers improve their habits, reduce insurance costs and notifies any pending or upcoming service and maintenance activities in advance.

Off road Vehicles

Cleaning Machines

Diesel Engines

Off-road vehicles such as forklifts, cranes are leased out by manufacturers for various use cases, it is important for the owners to monitor their location and the parameters to effectively control the usage. Telematics gateway integrated with GNSS, wide range of interfaces and J1939 protocol stack can act as a fleet tracker to determine live location updates and road conditions. With this data, owners can take preventive maintenance thereby reducing unnecessary fuel wastage, delays and cost.
Cleaning machines must adapt to their surroundings and the season becoming sweepers or snow blowers as required. Machines run all day in any condition and they operate on steep or uneven terrain. So, crucial vehicles information can be collected by Telematics Control Unit using sensors, GPS, J1939 protocol stack and this data is transmitted to the cloud in real-time enabling managers to get access about the key vehicle parameters to calibrate performance and efficiency.
Diesel engines operate for long hours in extreme working or environmental conditions, which makes them vulnerable to sudden failures and frequent breakdowns. The manufacturer needs an effective solution to remotely monitor their assets while on field at the end-user premise. J1939 Logger integrated with J1939 protocol stacks can provide valuable real-time insights from the machine, which can be analysed to determine the occurrence of any failure in advance and take preventive measures.
