Abstract

The invention discloses a method and device for collecting injection information of a vehicle urea solution. A command of injecting the vehicle urea solution to a current vehicle is received; the vehicle urea solution is injected, and the injection amount of the vehicle urea solution is metered automatically; and the identification information of the current vehicle is obtained, and the injection amount and the identification information are stored in a database correspondingly. According to the method and device for collecting the injection information of the vehicle urea solution, injection data of the injected solution can be collected automatically and quickly, so that intelligent injection of the vehicle urea solution is achieved, the workload of related workers is relieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a method and device for collecting filling information of urea solution for vehicles. Background technique [0002] As the requirements of domestic emission regulations become more and more stringent, many heavy-duty engine manufacturers adopt selective catalytic reduction (SCR) exhaust gas treatment technology. The main working principle of SCR is that urea is decomposed into NH at high temperature 3 and CO 2 , resulting in NH 3 As a reducing agent, reduce NOx in exhaust gas to N 2 . Urea solution for vehicles is an important must-have consumable in SCR technology, and it is suitable for cars, trucks, buses and heavy-duty off-road diesel engine vehicles equipped with SCR systems. [0003] The current urea filling stations for vehicles generally control the amount of addition manually and input the filling information manually, which cannot automatically and quickly ...
