Environmental protection detection system and method thereof based on OBD vehicle-mounted diagnosis system

Abstract

The invention discloses an environmental protection detection system and method based on an OBD vehicle-mounted diagnosis system. The invention relates to the technical field of automobile exhaust detection. The environmental protection detection system comprises an OBD vehicle-mounted diagnosis system. The OBD vehicle-mounted diagnosis system is provided with an OBD interface. The system also comprises an OBD environmental protection detection module and a wireless data communication uploading function module. The OBD environmental protection detection module is connected with the OBD vehicle-mounted diagnosis system through an OBD interface. The wireless data communication uploading function module is wirelessly connected with the OBD environmental protection detection module; real-timeengine information and tail gas emission data of a vehicle are obtained through the OBD environmental protection detection module; and standard inspection is carried out according to a data format andan operation flow required by a standard, and detection result data is uploaded to an environmental protection inspection system through a wireless data communication uploading function module, so that timely detection and sharing of the data are realized, supervision and tracing are facilitated, and the intelligence of automobile exhaust emission detection is improved.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust detection, and more specifically relates to an environmental protection detection system based on an OBD on-board diagnostic system and a method thereof. Background technique [0002] Automobile exhaust contains carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, lead, carbon particles and other impurity dust, etc. These substances are extremely harmful to humans and the entire ecological environment, among which CO, HC, NOx and particles are the main harmful substances. Emissions. [0003] Automobile exhaust emission has reached a very serious level in big cities. Although the country has a complete set of regulations on automobile exhaust emission, the exhaust gas inspection can only be carried out after the automobile enters the designated inspection point within the statutory time. Conventional exhaust gas detection methods include: use a five-gas exhaust gas analyzer t...
