Assistance system for black smoke inspections. Through the camera of your device, we virtualize the Ringelmann Scale methodology, used worldwide to measure the emission of black smoke from diesel engines and industrial chimneys. The inspection process is faster and more efficient and it is possible to inspect a greater number of vehicles and chimneys, thus allowing them to be sent to suitability, thus reducing the emission of black smoke and freeing the environment from tons of this residue. Virtual Ringelmann supports both vehicular and stationary surveillance methods. It was developed for industries and transport companies that need to implement the concept of environmental management in the administration and operation of pollutant emitters and who wish to be aligned with municipal, state, national, or international environmental legislation and standards such as 14001. Benefits of Virtual Ringelmann • Measurement Assessment of the conditions of the fleet or industrial chimneys supporting decision making for preventive and corrective actions. • Decision support It automatically identifies and records the pollution index emitted by the inspected source through the captured image. This information together with the registered image will allow a richer analysis of the characteristics of the measurements. • Confidence Generates evidence through photographic image captured during the inspection process. This image can be sent to the Virtual Ringelmann Portal (http://portal.virtualringelmann.com) to generate a decision support report. • Integration Allows the generation of inspection reports on the web portal as well as the creation of a history of the vehicular or stationary sources inspected • Convenience For large companies, it will be possible to maintain a single technical person responsible for analyzing the measurements without leaving the company using the reports issued by the portal. The measurements will be more constant, however, made by common people, without the need for analysis training as it is with the PAPEL scale, bringing more credibility and economy to the inspection process. Virtual Ringelmann is the evolution of a product created in 1888 in order to facilitate inspection and monitoring of smoke emitters.
