Remote sensing device (RSD)

The RSD offers a robust and reliable solution for real-time vehicle emissions monitoring, combining cutting-edge sensing technology with powerful AI capabilities. Whether deployed in portable or fixed configurations, the device ensures accurate, continuous, and automated emissions analysis, making it an invaluable tool for monitoring environmental impacts and vehicle performance.

How It Works

The RSD accurately determines the concentrations of various pollutants present in the exhaust plume of each vehicle. By integrating computer vision technology, the device also analyzes the vehicle’s characteristics and behavior, including speed and acceleration, at the time the emissions are measured.

Key Features

Accurate Emissions Measurement

The RSD is capable of measuring critical and regulated pollutants, providing detailed analysis of the vehicle’s exhaust. The pollutants detected include:

• CO (Carbon Monoxide)
• CO2 (Carbon Dioxide)
• NO (Nitrogen Monoxide)
• NO2 (Nitrogen Dioxide)
• HC (Hydrocarbons)
• NH3 (Ammonia)
• PM (Particulate Matter)

The device analyzes emissions from tailpipe exhausts, as well as evaporative emissions resulting from leaks. Each vehicle’s emission record consists of 100 measurements captured in just 0.5 seconds, providing precise data. Emissions are typically expressed in pollutant ratios to CO2, fuel-specific emissions, or even emissions per traveled distance (g/km) based on appropriate assumptions.

Automatic and Autonomous Calibration

The RSD features an automatic self-calibration system that ensures accuracy (±10%). It uses sealed internal cells with known concentrations of multiple gases to regularly verify system performance. This feature applies to both portable and fixed systems, enabling 24/7 monitoring with unattended operation. This system also ensures the validity of measurements for metrological and legal purposes, providing a method of instrument verification without the need for human intervention.

AI-Powered Visual Analysis

The RSD is equipped with Opus Sensing Drive©, a proprietary Artificial Intelligence (AI) technology that provides real-time visual analysis of individual vehicles. Using the camera integrated into the RSD, the device can capture and analyze details such as:

• Vehicle type
• License plate number
• Vehicle speed and acceleration
• Vehicle Specific Power (VSP)
• Brand and model
• Body and license plate color

Dual-Lane Monitoring

The RSD is capable of simultaneously measuring emissions from vehicles in two lanes of traffic. It can function without the need to place any devices on the road or above the lanes, and it automatically identifies and marks invalid events when vehicles pass in parallel.
