Overview

The ERMS2000-M movable vehicle exhaust remote sensing system, developed by our company, is suitable for mobile enforcement of city roads and stationary enforcement of single lane. It can detect the CO, CO2, NO, HC and opaque smoke intensity in gasoline and diesel vehicle exhaust through TDLAS, UV-DOAS, weak signal detection technology and image recognition technology with fast response time (＜0.5s) as well as simple system operation. The measured signals are transmitted through WIFI, and it can be connected to LED screen to display vehicle exhaust emission information. Dispensing with sample extraction, the vehicle emission testing machine avoids the interference and uncertainty from sampling to reflect the pollution condition of vehicle exhaust emission objectively.

Feature Of ERMS-2000-M Mobile Vehicle Exhaust Telemetry System

 

• Small size and handiness:

highly integrated design with small size and handiness, which is beneficial for movable operation;

 

• Efficient site layout:

adopt a unique optical path adjustment module, able to complete site layout in a very short time;

 

• 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;

 

• 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-M Mobile Vehicle Exhaust Telemetry 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 a scientific basis for decision maker and vehicle exhaust pollution control measures, thus achieve the goal of online monitoring for the city vehicle pollution.
