OBD remote monitoring of heavy diesel vehicles

Motor vehicle emissions are one of the important sources of urban air pollution. According to relevant data, the emissions of nitrogen oxides and particulate matter from diesel vehicles account for 68.3% and 77.8% of the total vehicle emissions, respectively. Therefore, with the highlight of the problem of exhaust pollution, the implementation of the installation of heavy diesel vehicles with OBD equipment has become one of the important measures to win the blue sky defense battle in our town.

According to reports, OBD is the abbreviation of On-Board Diagnostic in English, translated as "vehicle automatic diagnostic system", that is, a system that monitors the operating status of the engine and the working status of the exhaust gas post-processing module at any time, and once it is found that it may cause emissions to exceed the standard, Police will also be issued immediately; by installing OBD equipment on heavy-duty diesel vehicles, owners can keep abreast of the parameters of the vehicle ’s driving at any time, realizing long-term dynamic monitoring of the vehicle ’s emission status, which is convenient for timely repair and maintenance of the vehicle, thereby making heavy-duty vehicles Pollution emissions from diesel vehicles have been effectively improved.

Therefore, strengthening OBD remote monitoring of heavy diesel vehicles is one of the important tasks of environmental protection departments. In 2017, the Ministry of Environmental Protection issued the "Technical Policy for the Prevention and Control of Motor Vehicle Pollution", which puts forward regulatory requirements for the inspection of OBD systems of in-use vehicles, and strengthens the actual emission supervision of operating vehicles. In 2018, the National Wu Academy released the "Three-Year Action Plan to Win the Blue Sky Defence War", which requires strengthening the monitoring capacity of mobile source emissions, building and improving remote sensing monitoring networks, building a remote monitoring system for heavy-duty diesel vehicle on-board diagnostic systems, and strengthening non-road mobile machinery and ships. Pollution prevention, the establishment of a comprehensive monitoring system for the integration of the world, the car and the vehicle. In 2019, the 11 departments jointly issued the "Action Plan for the Tightening of Pollution Control of Diesel Trucks". By the end of 2020, the emission rate of diesel trucks will be significantly improved, the quality of diesel and vehicle urea will be significantly improved, and the total emissions of nitrogen oxides and particulate matter from diesel trucks will be significantly reduced. The concentration of nitrogen dioxide in the air of cities in key regions has gradually decreased, and the capacity and level of motor vehicle emission supervision has been greatly improved.

ZWIN-OBD06 is a management terminal for remote emission of heavy diesel vehicles OBD. The whole set of equipment adopts car-level design and integrates J1939 CAN bus protocol data, national secret SM2 encryption, 4G cellular network, GPS + Beidou satellite positioning, FLASH storage and other functions. It is installed and applied to heavy diesel vehicles for collection, storage and transmission Vehicle OBD information and engine emission data.
