Abstract: In order to solve the problem of wide distribution of non-road mobile machinery and lax emission supervision, a comprehensive management and control platform for non-road mobile machinery based on B/S architecture is designed. We took the urban area as the monitoring unit to remotely monitor the emission and operation status of non-road mobile machinery. Through general survey and registration system and vehicle terminal technology, the platform collected the basic information and operation status of non-road mobile machinery and visualized on the Web platform, so as to warn for machinery with excessive emissions. After the platform design was completed, it was deployed in Jingzhou City, Hubei Province. After more than a year of verification in real vehicles, the platform can run stably and achieve the expected results.
