On-line automatic diagnosis and remote monitoring system and method for automobile emission

Abstract

The invention discloses an on-line automatic diagnosis and remote monitoring system and method for automobile emission, and relates to an automobile emission monitoring system. The monitoring system comprises an automobile engine (100) and a GSM (global system for mobile communications) sub system (300), and is provided with an engine management sub system (200) and an OBD (on-board diagnostics) remote monitoring sub system (400); the engine management sub system (200) is connected with the automobile engine (100) so as to diagnose the automobile engine (100) on line; and the engine management sub system (200), the GSM sub system (300) and the OBD remote monitoring sub system (400) are communicated through a mobile communication network provided by the GSM sub system (300) in a mode of short massages. The monitoring system provided by the invention can master and control automobile states timely and accurately, is high in timeliness, can form a monitoring network in wide range, is wide in coverage, can save recourse cost, is high in extendibility, and is suitable for all domestic automobile vehicles.

Description

technical field [0001] The invention relates to a vehicle emission diagnosis and monitoring system, in particular to a vehicle emission online automatic diagnosis remote monitoring system and a method thereof. Background technique [0002] The automobile industry has developed rapidly in recent years. China has become the second largest producer and largest consumer of automobiles in the world, and the annual output of motorcycles has long ranked first in the world. With the continuous growth of the number of motor vehicles, the emission of motor vehicle pollutants (HC, CO and NOx) in my country has increased significantly, and the average proportion of motor vehicle exhaust pollutants in urban air pollution has increased significantly. Prevention and control of motor vehicle exhaust pollution has become one of the main tasks of urban air pollution control. [0003] In April 2005, the State Environmental Protection Administration announced the "Light Vehicle Pollutant Emiss...

Secondly, the detection method is not scientific and not strict, resulting in the cars that have passed the annual inspection becoming "year-round environmentally friendly cars", and no one cares about them anymore

[0005] The OBD standard currently implemented in China is close to the OBDII of the United States or the EOBD standard of Europe. Although the OBD system can detect the fault and light the fault light to warn the driver when the engine system fails and the emission exceeds the standard, whether the driver accepts it? The warning of the fault light, the current OBD system can't do anything

If the driver does not repair the vehicle with excessive emissions before the annual vehicle inspection, the relevant management department will not know
