Abstract: To effectively collect the multisource heterogeneous equipment data during tunneling, the parallel collection scheme and technology of scattered and heterogeneous equipment data are studied based on the operation data characteristics of construction group equipment. Based on the construction of the data collection system framework and collection implementation, the stream-based data management is analyzed according to the characteristics of multidimensional and continuous data generation of equipment. Furthermore, a forwardoriented optimal concurrency control system is developed to enable the centralized and combined acquisition of multisource heterogeneous data. Meanwhile, the research and development practice of forwarding optimistic concurrent data acquisition management and automatic networking technical scheme of acquisition equipment are studied, and a data acquisition terminal with multiprotocol integration, multiinterface concurrent acquisition, ad hoc networking, and independent transmission is developed to realize the realtime extraction of operation data of tunnel construction equipment, such as gantry crane and mud water separation system. The results show that the proposed multi-source heterogeneous data acquisition technology scheme can effectively address the multi-source heterogeneous data acquisition problem.
