Vehicle-mounted portable tail gas discharge measurement system based on wireless transmission

Abstract

The invention belongs to the technical field of mobile source discharge testing, and provides a vehicle-mounted portable tail gas discharge measurement system based on wireless transmission. System hardware is composed of a gas-state pollutant module 1 used for measuring vehicle discharge, a fine particle module 2, an engine operation parameter measurement module 3, a speed and acceleration measurement module 4, a discharge flow measurement module 5, a data storage and transmission module 6, a near-distance communication protocol transmission module 7, a wifi transmission module 8 and an ultra -distance real-time online transmission module 9. Software is composed of host software 10, a third-party application program 11, a digital display and data calculation module 12, an ultra-distance tail gas discharge real-time monitoring platform 13 arranged in an open-source mode, and a data continuous diagnosis and processing calculation module 14. According to the system provided by the invention, a novel mobile source tail gas discharge measurement system based on an actual working condition is erected by use of a wireless technology, a far-distance real-time monitoring platform of mobile source tail gas discharge is established, acquired data can be stored, transmitted and processed in real time, and an accurate discharge result can be obtained.

Description

technical field [0001] The invention belongs to the technical field of mobile source emission testing, and in particular relates to an exhaust emission measuring system suitable for gasoline and diesel hybrid vehicles under realistic working conditions. Background technique [0002] Mobile sources are one of the important sources of air pollutants in various cities. Mobile sources include road mobile sources and non-road mobile sources. Among them, road mobile sources are mainly gasoline vehicles, and non-road mobile sources are mainly high-power diesel machinery. The exhaust gas emitted by them is Contains pollutants such as gaseous and particulate matter. With the strengthening of mobile source emission control in my country, the management and control methods for mobile sources will be more diverse, the demand for exhaust emission measurement equipment under realistic working conditions will increase correspondingly, and the measurement requirements will increase accord...

AI Technical Summary

Problems solved by technology

[0004] The current mobile source vehicle emission measurement system mainly has the following shortcomings: 1. There is no complete integrated measurement system on the market

2. The entire measurement system is large in size and weight, and it is not convenient to carry and install it when using it.

3. The integration of hardware and software is not high, and the measurement systems for gasoline and diesel vehicles need to be designed separately, which increases the cost

4. There is no overall hardware and software integrated wireless vehicle emission measurement system on the market, which cannot promote real-time monitoring of exhaust emission data under real working conditions
