Vehicle exhaust gas monitoring system based on RFID (radio frequency identification devices)

Abstract

The invention provides a vehicle exhaust gas monitoring system based on an RFID (radio frequency identification devices), which relates to the technical field of wireless sensing. The vehicle exhaustgas monitoring system comprises an exhaust gas detection unit, an active RFID tag and a RFID card reader. The exhaust gas detection unit is arranged at an exhaust gas emission pipe orifice of a vehicle and detects the exhaust gas information of the vehicle in real time. The active RFID tag is electrically connected with the exhaust gas detection unit and acquires the exhaust gas information acquired by the exhaust gas detection unit, and comprises a RFID tag body, a solar panel and a lithium battery, the solar panel converts the solar energy to electric energy to directly supply power to the RFID tag body and can also supply power to the lithium battery first. The RFID card reader is arranged at a traffic light crossing of a road and automatically reads the tag information of all active RFID tags within the identification distance range of the RFID card reader. The exhaust gas information of the vehicle can be acquired in real time without examining the vehicle by driving the vehicle to a vehicle administration office, so that a great amount of time of a car owner can be saved.

Description

technical field [0001] The invention relates to the technical field of wireless sensing, in particular to an RFID-based vehicle exhaust monitoring system. Background technique [0002] The traditional vehicle exhaust detection method adopts the chassis dynamometer test method. The working principle of this method is: in the room, combined with the chassis dynamometer and the gas analyzer, the exhaust emission of the motor vehicle is tested under the preset driving conditions of the motor vehicle. . Or use the vehicle exhaust emission detector to detect the emission concentration value of automobile exhaust or the emission per unit mileage. This method can only read the exhaust emission of a certain vehicle when it is parked or simulated driving conditions on the bench. . Motor vehicles must be tested according to fixed driving conditions, so it cannot truly reflect the exhaust emissions on the actual road, and the emission test system is too large and difficult to operate,...

AI Technical Summary

Problems solved by technology

Or use the vehicle exhaust emission detector to detect the emission concentration value of automobile exhaust or the emission per unit mileage. This method can only read the exhaust emission of a certain vehicle when it is parked or simulated driving conditions on the bench.

Motor vehicles must be tested according to fixed driving conditions, so it cannot truly reflect the exhaust emissions on the actual road, and the emission test system is too large and difficult to operate, and it often takes a lot of time to get the tested vehicles result

In addition, drivers can only find problems with vehicle exhaust emissions when they go to the vehicle management office for inspection during the annual inspection, and cannot grasp the status of vehicle exhaust emissions in real time
