Vehicle emission remote online monitoring platform and system and vehicle-mounted terminal

Abstract

The invention relates to a vehicle emission remote online monitoring platform and system and a vehicle-mounted terminal. The platform acquires static data and real-time dynamic data of a vehicle through a data acquisition module; a prediction module obtains a DPF carbon deposition rate model by using an evaluation model based on Weibull distribution reliability; the prediction module also calculates the average carbon deposition interval time according to the DPF carbon deposition rate model, the static data and the real-time dynamic data, and predicts the carbon content to obtain a prediction result; a data storage and analysis module performs analysis and statistics on the static data and the real-time dynamic data to obtain an analysis and statistics result, and stores the analysis and statistics result and the prediction result in a database; and a front-end UI calls the data in the database through an API. According to the platform, intelligent prediction under mass data is realized, and data support is provided for decision-making of vehicle governance policies.

Description

technical field [0001] This application relates to the technical field of diesel engine exhaust emission monitoring, in particular to a vehicle emission remote online monitoring platform, system and vehicle-mounted terminal. Background technique [0002] It is not too late to start the prevention and control of motor vehicle pollution in China. The supervision and management of motor vehicle emissions has been implemented since the 1980s. In 1997, the National Motor Vehicle Emission Monitoring Center was formally established. Looking back, China's motor vehicle pollution prevention and control work has developed from the initial management of a single motor vehicle emission inspection agency to today's multi-means supervision model such as road inspection, household sampling, and remote sensing monitoring. From the pollution control of excessive vehicles to the current Comprehensive improvement of "road-oil-vehicle", from single-vehicle supervision at the source to today's i...

Problems solved by technology

[0003] However, due to the mobility of motor vehicles, it is difficult to monitor them at source

In addition, the current environmental protection inspection has not achieved national networking, and there are problems such as lack of basic data. As a result, vehicles found to exceed the standard in remote sensing monitoring and road inspections cannot be effectively supervised for subsequent maintenance after punishment, and old vehicles are eliminated. It brings certain difficulties; from a technical perspective, compared with other departments, the motor vehicle exhaust pollution management department needs more comprehensive and professional technical knowledge
