**4. High speed railway ballastless track construction intelligent management and control technology**

The intelligent construction control technology of ballastless track is composed of four parts: automatic data collection, intelligent transmission, big data storage, and the whole process supervision of the control platform. The information equipment interconnected with the management and control platform, such as the intelligent measurement and control terminal for base positioning and track slab fine adjustment, and the collection device for track geometry and position, are used to realize the automatic upload of relevant information such as construction process measurement and laying. Using big data storage technology, a distributed data warehouse is built on the server to realize the orderly, regular and structured storage of massive amounts of *Perspective Chapter: Intelligent Construction Technology of Ballastless Track for High-Speed… DOI: http://dx.doi.org/10.5772/intechopen.109611*

data. Through the construction intelligent management and control platform, the massive amount of data in the data warehouse are screened, extracted, analyzed and processed. In combination with the relevant requirements of the slab track construction acceptance standards, the data is judged to exceed the limit. Through the early warning cloud system, various ways of early warning and prediction are realized, so as to realize the interconnection between the construction site and the remote platform, the interconnection between the construction workers and the management personnel, and the control of the process flow, as well as realize the whole process management of quality (**Figure 13**).

The intelligent management and control technology takes the intelligent management and control platform as the core, and takes "design data achievements" and "dynamic data files of the whole construction process" as the data basis. The core of management and control is the progress and accuracy of the whole process of

ballastless track construction. Analyze, judge and count the progress and quality of track construction according to the set tolerance requirements by quickly analyzing the on-site construction survey data. It will provide detailed and convenient statistical information for project construction managers, achieve the dynamic management of track construction process on site, improve management efficiency and promote construction quality.

The main functions are as follows:
