Description

Method for monitoring and controlling carbon emission in real time in production and construction of epoxy asphalt mixture Technical Field The invention relates to the technical field of road building material monitoring and control, in particular to a method for monitoring and regulating carbon emission in real time in epoxy asphalt mixture production construction. Background The epoxy asphalt mixture is used as a high-performance pavement material, and in the production and construction process, high-temperature process links such as asphalt heating, aggregate drying, mixture stirring, paving and compacting are needed. These processes, accompanied by the combustion of fossil fuels and the thermal reaction of the materials, are critical phases of carbon emissions (mainly CO2, CO) production. Currently, carbon emission management for this process is largely dependent on traditional means. One is to rely on periodic manual detection and off-line sampling followed by analytical accounting in a laboratory. The method has serious hysteresis, and when the analysis result is discharged from the furnace, the corresponding production batch is finished, and the fact that the carbon emission exceeds the standard is realized, so that the instant guidance of the production process can not be realized. Secondly, a macroscopic estimation method based on material balance and emission factors is adopted. Although the method can evaluate the total emission level, the method is difficult to reflect the instantaneous emission dynamics generated by the fluctuation of working conditions (such as the change of fuel quality and the fluctuation of equipment state) on the production line, has insufficient precision, and can not locate specific abnormal emission points. A common drawback of the above-described conventional modes is that they are both "post-hoc" and "passive monitoring" in nature. The whole process lacks a real-time data sensing network covering the whole process of production and construction, so that a real change curve of carbon emission in seconds or minutes cannot be obtained. More importantly, after the abnormal emission is detected or calculated, the prior art system lacks instant intervention capability linked with production equipment, and key process parameters such as heating temperature, fuel ratio and the like cannot be automatically and intelligently adjusted in the early stage of the exceeding trend of the emission, so that the occurrence of the exceeding emission is restrained from the source. Therefore, the field is in urgent need of a carbon emission management method capable of realizing real-time sensing, intelligent early warning and dynamic regulation throughout the whole process of epoxy asphalt mixture production and construction, so as to overcome the hysteresis and the passivity of the prior art and realize the fundamental transition from 'post accounting' to 'in-process control'. Based on the method, a method for monitoring and dynamically regulating carbon emission in real time in production and construction of the epoxy asphalt mixture is provided, so that the problems are solved. Disclosure of Invention The invention aims to provide a method for monitoring and dynamically regulating carbon emission in real time for production and construction of an epoxy asphalt mixture, which aims to solve the problems that the traditional carbon emission management method has hysteresis and insufficient precision and cannot perform instant intervention on the production process, so that the carbon emission is high in risk of exceeding standard and difficult in environment-friendly compliance. In order to solve the technical problems, the invention adopts the following technical scheme: a method for monitoring and dynamically regulating carbon emission in real time in production and construction of an epoxy asphalt mixture comprises the following steps: S1, dividing a key carbon emission procedure in the production and construction process of the epoxy asphalt mixture, wherein the key carbon emission procedure comprises aggregate drying and heating, epoxy asphalt mixture mixing, epoxy asphalt mixture transportation, epoxy asphalt mixture paving and rolling; S2, respectively arranging sensors in a key carbon emission process; S3, constructing a carbon emission prediction model, embedding the carbon emission prediction model into a cloud processing system, inputting data acquired by a sensor into the cloud processing system, and calculating and predicting the carbon emission; S4, comparing the output carbon emission amount with a preset carbon emission threshold, and regulating and controlling the technological parameters of the key carbon emission procedure when the carbon emission amount is larger than the carbon emission threshold. Preferably, in S2, the sensor arrangement method is specifically, An aggregate drying and heating procedure, wherein n carbon dioxide sensors and n carbon monoxide sensors a
