The invention relates to the technical field of low-carbon road building material monitoring and control, and discloses an epoxy asphalt mixture production construction carbon emission real-time monitoring and regulation method. The system comprises a sensor network module, a data processing and transmission module, a cloud intelligent analysis module, an automatic adjustment module and a human-computer interaction interface module. Multiple types of sensor nodes are arranged on a production line and a construction site, CO2 concentration, fuel consumption, temperature and other parameters are collected in real time, and the parameters are preprocessed by a data processing and transmission module and then uploaded to a cloud system for intelligent analysis and threshold judgment. The system can automatically adjust the combustion device, the heating equipment and the mixing power according to the real-time emission state, and dynamic control over carbon emission and energy consumption optimization are achieved. The system can generate a real-time monitoring curve and a historical report, has abnormal early warning and intelligent decision support functions, and realizes accurate monitoring and intelligent management of carbon emission of the epoxy asphalt mixture in the whole process from production to construction.

This invention provides a near-zero carbon emission control system and method for internal combustion engines based on hydrogen fuel-assisted combustion. It includes an intelligent hydrogen fuel supply subsystem for receiving engine torque demand signals and calculating initial hydrogen supply parameters based on these signals; a combustion control and optimization subsystem for real-time monitoring of the combustion state in the engine combustion chamber and establishing a three-variable online optimization model of the in-cylinder combustion quasi-dimensional dynamics model based on the combustion state; and a collaborative main control subsystem for solving for optimal control parameters, dynamically optimizing and adjusting supply parameters and / or ignition parameters using a composite control strategy, predicting future engine load changes, and controlling the hydrogen supply. This invention significantly suppresses nitrogen oxide formation while ensuring high indicated thermal efficiency, and simultaneously avoids excessive emissions due to air-fuel ratio imbalance during transient processes, thus improving vehicle drivability and fuel economy.
