ERMS-2000-V Vertical Stationary Vehicle Exhaust Remote Sensing System

ERMS-2000-V Vertical Stationary Vehicle Exhaust Remote Sensing System

Overview

ERMS2000-V vertical stationary vehicle exhaust remote sensing system is a system that sets above the multi-lane and monitors the exhaust pollutants of every moving vehicle on each lane, It can measure CO, CO2, HC, NO and opaque smoke intensity rapidly and accurately; record the license, speed and acceleration of the car as well as the environmental parameters on micro air station. The system is composed of a gas monitoring unit, opacity monitoring unit, speed/acceleration monitoring unit, license capture unit, micro weather station and IPC of TDLAS and UV-DOAS technology. The system is with rapid and effective measurement, high automation and detection rate, less maintenance; each lane works independently, measures simultaneously without mutual interference.

Feature Of ERMS-2000-V Vertical Stationary Vehicle Exhaust Remote Sensing System


  • Stationary overlook installation:
dispensing with repetitive installation and overcome the accurate detection for multi-lane that current remote device cannot achieve to make multi-lane independent and simultaneous detection possible; not required people for watching to economize on manpower;

  • Simultaneous monitoring on gasoline/diesel vehicle:
adopt spectrum technology of high stability, which can detect emission pollutants of both gasoline and diesel vehicles at the same time to greatly reduce device cost;

  • Narrow-wave radar speed measurement:
adopt narrow-wave radar speed measurement with low microwave irradiation, low power consumption, long service life, high stability, and reliability; locate target accurately to avoid adjacent clutter interference; fast response time to ensure the capture rate and instantaneity of the target;

  • Integrated calibration system:
four components (CO, CO2, HC, NO) can be calibrated simultaneously, support both manual/auto calibration with simple operation and high efficiency;

  • Large measuring range:
a portal frame is as high as 4-6 meter, which is able to monitor emission for different types of vehicle; full road coverage without occupying lane and affecting traffic;

  • Real-time data matching:
real-time data matching without post-processing; output monitoring results in real time; combined with vehicle identification technology, screen excessive emission vehicle;

  • Remote online monitoring system:
online monitor battery status, calibration state, system alarm information, wireless communication signals and etc. Remote monitoring and operation, convenient for the operator to monitor system parameters;

  • Auto record and storage:
logs will record all the operating and alarm information for query and tracing, which is convenient for problem processing and solving. The outage will not affect data storage

Application Of ERMS-2000-V Vertical Stationary Vehicle Exhaust Remote Sensing System


The product is used for the online monitoring of CO, CO2, NOx, HC, and opacity in vehicle exhaust emission. All parts are in the deft design and convenient for installation, which can be installed in all road sections and toll gates. It can form an online monitoring web through appropriate deployment in the typical area. Combined with network transmission technology,it can achieve data sharing and result display with environment detection center and vehicle management center, which provide the scientific basis for decision maker and vehicle exhaust pollution control measures, thus achieve the goal of online monitoring for the city vehicle pollution.
