Construction process data link construction method

According to the construction process data link construction method, the output data of the immediately preceding task is determined according to the input data requirement of the immediately succeeding task, and the integrity of the output data is guaranteed. According to the method, the sequence of each process in the construction process, input data and output data of each process, and constraint information such as human, machine, material, ring (operation space) and other resources and methods (specifications) used in process execution can be realized, a basis is provided for research and development of intelligent construction products, and the applicability of the intelligent construction products is greatly improved. According to the process data chain, the input and output processes of the product data in each step in the process are embodied, the process data can be comprehensively collected according to the process data chain, and the quality of the output product can be checked according to the co
