The Design and Implementation of the Terminal in a Vehicle Exhaust Real Time Detecting System

Abstract

This research proposed a real time exhaust measuring system and realized automatic acquisition of exhaust data. In this research, VMT (Vehicle Mounted Terminal) which is integrated with GPRS module, GPS module,exhaust detection unit and microcontroller unit, collected the concentration of CO2, CO and HC and the vehicle location which were then sent to MC (Monitoring Center) via GSM/GPRS net. In this way, both exhaust transient data under daily running and vehicle location are available to environment protection department, which provided a new method to rid high emitting vehicles in urban areas. The system has extensive practical value in vehicle exhaust online detecting, remote vehicles management and environment monitoring.
