The invention provides a heavy-duty vehicle emission monitoring system. The heavy-duty vehicle emission monitoring system comprises an environment protection monitoring platform, wherein the environment protection monitoring platform comprises an application layer, a service layer and a server; the application layer comprises an oil station communication interface used for achieving the data interaction between the environment-friendly monitoring platform and an oil station, and a delivery communication interface used for achieving the data interaction between the environment protection monitoring platform and the delivery system, and an OBD communication interface used for achieving the data interaction between the environment protection monitoring platform and a vehicle-mounted OBD; theservice layer comprises a data processing unit; the functions of the data processing unit include a urea consumption and an environmental protection contribution coefficient; a field in an OBD communication interface receiving data frame includes identification, rotating speed, torque, vehicle speed, air intake and urea liquid level of a vehicle; a field in an OBD communication interface transmitting data frame includes oil station record information; the environment protection monitoring platform further comprises a urea box database; and the urea box database is used for storing three-dimensional model information of a urea box. By using the monitoring system, the actual emission of the heavy-duty vehicle in roads is effectively monitored.
Description
technical field [0001] The invention belongs to the field of monitoring systems, in particular to a heavy-duty vehicle emission monitoring system. Background technique [0002] With the upgrading of heavy-duty vehicle platoon standards, in order to meet the standard requirements, the vehicle emission control technology is complex, including after-treatment technology and OBD requirements, and users need to add urea to ensure that the emission meets the standard. However, due to the lack of regulatory methods and the trend of interests, diesel vehicle emissions are now seriously out of control, mainly including: heavy-duty vehicle NOx emissions exceed the standard; manufacturers disable OBD alarm and torque limit functions; OBD has been tampered with; users do not add urea. [0003] At present, there is still a lack of practical verification on how to incorporate remote monitoring technology into the heavy-duty vehicle emission standard system to realize remote monitoring of ...
