Application of J1939 to OBD2 cable in data acquisition and analysis

The J1939 to OBD2 cable has important applications in data acquisition and analysis, mainly reflected in the following aspects:

Collect vehicle operating status data

Basic parameter monitoring: Through this cable, basic operating parameters such as truck engine speed, torque, coolant temperature, and intake pressure can be collected.

Emission related data collection: Collect emission data of nitrogen oxides, particulate matter, and other pollutants in truck exhaust. With increasingly stringent environmental requirements, these data help fleet managers understand vehicle emissions, ensure compliance with environmental standards, and provide a basis for optimizing engine combustion strategies to reduce emissions pollution.

Transmission status monitoring: Collect oil temperature, oil pressure, and shifting information of the transmission. For example, by monitoring the oil temperature of the gearbox, the working load and heat dissipation of the gearbox can be determined, preventing gearbox failures caused by high oil temperature and extending the service life of the gearbox.

Analyze driving behavior data

Rapid acceleration and deceleration analysis: Using collected data such as speed and acceleration, analyze the driver's rapid acceleration and deceleration behavior. Frequent rapid acceleration and deceleration not only increase fuel consumption, but also cause significant wear and tear on vehicle components. By analyzing these data, training and guidance can be provided to drivers to help them develop good driving habits and reduce operating costs.

Research on the relationship between driving speed and fuel consumption: Combining the collected vehicle driving speed data with fuel consumption data, analyze the fuel consumption situation in different speed ranges. Thus providing drivers with economical driving speed recommendations, enabling the vehicle to maintain low fuel consumption during operation and improve fuel economy.

Idle time statistics: Accurately count the idle time of the vehicle. Long term idling can lead to fuel waste and engine carbon buildup. By analyzing idle time data, corresponding management measures can be developed to reduce unnecessary idling, lower operating costs, and reduce environmental pollution.

Support remote management of vehicle fleets

Vehicle position and driving trajectory tracking: Combined with global positioning system (GPS) data, real-time tracking of vehicle position and recording of driving trajectory can be achieved through vehicle operation data collected through J1939 to OBD2 cable. Fleet managers can always understand the location information of vehicles, arrange transportation tasks reasonably, and improve transportation efficiency. Meanwhile, analyzing the driving trajectory can help optimize transportation routes and reduce unnecessary mileage.

Remote fault diagnosis and warning: The collected data can be transmitted to the remote monitoring center through a wireless communication module. When a vehicle malfunctions, technicians can promptly obtain fault information, conduct remote diagnosis, and determine the severity and possible causes of the fault. For some potential faults and hidden dangers, early warning can be issued to allow the fleet to prepare for maintenance in advance, avoiding sudden vehicle failures on the road and affecting transportation tasks.

Vehicle performance evaluation and maintenance plan development: Based on long-term collected data, evaluate the performance of each vehicle to understand the wear and tear of its components and performance trends. Based on these analysis results, develop personalized maintenance plans, arrange vehicle maintenance and repair time reasonably, ensure that the vehicle always maintains a good operating condition, and avoid resource waste caused by excessive maintenance.
