High-precision building construction carbon emission real-time metering method and system
ActiveCN119398318AHigh measurement accuracyAccurate emissionsResourcesCommerceControl engineeringThe Internet
The invention provides a high-precision building construction carbon emission real-time metering method and system, and belongs to the field of carbon emission calculation. The invention aims to solve the problem that during carbon emission calculation in building construction, a calculation boundary needs to be determined, repeated calculation or missing lacks are easy to occur, and large access exists between a metering result and actual carbon emission. The construction activity consumption data is collected through an automatic data collection means and uploaded to the system platform through the Internet of Things, and finally the carbon emission data of each subentry construction activity is calculated in real time and analyzed and displayed. According to the method, carbon emission calculation is considered as a whole, the carbon emission of the whole project is explored from overall resource input and output, detailed analysis of internal process links is avoided, the problem of determining the internal boundary of the project for multiple times and the influence of construction uncertainty are avoided, and the construction efficiency is improved. And moreover, the calculation boundary is clear, the calculation process is simple, the calculation result precision is very high, and the method has relatively high operability and popularization value.
