Abstract

The invention relates to a urea tank diagnostic system. The system comprises a post-treatment system controller ACU, an electric control unit E-box and computer, a urea tank diagnostic control systemis installed on the computer, the urea tank diagnostic control system comprises a safe access unit, a super-control test function unit, a fault clearing function unit, a real-time monitoring unit, a controller signal timeout checking function unit, an analog controller function unit, a data analysis function unit, the real-time monitoring unit comprises a controller static information reading module, an ACU signal reading module, an ECU signal reading module, an E-box signal reading module and an instrument signal reading module. The method is reasonable in concept, the method is stable in operation and use, good in diagnosis effect, high in efficiency and convenient to sell, the current state of the post-processing system can be read by the after-sales person, the current fault can be removed, can execute an over-control test and provide a diagnosis tool for after-sales and after-sale work.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis of post-processing systems, in particular to a diagnosing system for a urea tank. Background technique [0002] The traditional urea tank diagnostic instrument is easy to fail when passing security access, resulting in the lock of the controller. The company's sales and after-sales personnel cannot read the current status of the after-treatment system, cannot clear the current faults, and cannot perform the override test. Seriously affected the diagnostic efficiency and diagnostic effect of the urea tank. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the traditional urea tank diagnostic instrument is easy to fail when accessing safely, resulting in the lock of the controller. In view of the problem of control testing, a method with reasonable conception, stable operation, good diagnostic effect and high efficiency is proposed. The s...
