Automobile exhaust double idle detection system and method therewith for detecting automobile exhaust

Abstract

The application provides an automobile exhaust double idle detection system and a detection method of automobile exhaust. The system includes an intelligent cell phone, a gas analyzer, an exhaust probe, a rotation speed sensor, and a mobile detection system main machine. A probe end of the rotation speed sensor is arranged on an outlet of an exhaust pipe of a to-be-detected vehicle, while an information output end on the other end is connected to the gas analyzer. The rotation speed sensor is mounted on the to-be-detected vehicle to detect the rotation speed of an engine on the vehicle. An information output end of the rotation speed sensor is connected to the gas analyzer. The gas analyzer is connected to the mobile detection system main machine. The intelligent cell phone, in a wireless communication manner, is connected to the mobile detection system main machine and serves as an operation terminal. An operator holds the cell phone and operates the vehicle according to hint on the cell phone. The system achieves information interaction between the mobile detection system main machine and the intelligent cell phone, wherein detection results of the vehicle are displayed on the intelligent cell phone, so that the system can be operated by one person and saves space and corollary equipment.

Description

technical field [0001] The invention relates to a dual-idle detection system for automobile exhaust, in particular to using a smart phone as an operation terminal for operation, detection and information entry of the inspected vehicle. Background technique [0002] In order to prevent and control air pollution and control motor vehicle emissions, the state promulgated and implemented GB18285-2005 "Limits and Measurement Methods of Pollutant Emissions from Ignition Engine Vehicles (Double Idle Speed ​​Method and Simple Working Condition Method)", which stipulates that the double idling speed method is used as a vehicle For the emission detection method, the double-idle speed method requires fewer and simpler detection equipment and site requirements than the simple working condition method. This method is often used by environmental protection departments in roadside monitoring and flow detection. The detection process needs to instruct the operator to control the detected v...
