Vehicle Exhaust Telemetry System
This product is designed for on-line automatic monitoring vehicle emission of CO, CO2, NOx, HC, and tail gas opacity. Parts design is exquisite, easy installation and flexible. It is suitable for installation in the city road and tollgate. By providing real time monitoring data to control center, the system supports relevant bureaus to supervise and control vehicle emissions of the entire city.
Technical principle
In measuring field, vehicle exhaust remote sensing monitoring unit measures running state information through vehicle pollution emission information, speed/ acceleration units, and collects the license plate information via license plate identification system at the same time. During measurement, the atmospheric environment parameter monitoring system collects the environmental parameters for more accurate measurement and analysis. It realizes both the monitoring and management towards system, as well as real time analysis on the working state of monitoring system at the same time. All the units control and operate through the software-controlling computer of specialized vehicle exhaust remote sensing monitoring system on measurement site.
