The platform is divided into ** architecture, which is the sensor-based front-end perception layerThe middle layer is based on calculation, transmission and control, and the control center is based on platform software, data storage, calculation and analysis.
In accordance with the principle of authority setting and hierarchical management, the platform shares resources with enterprises, engineering project departments, and first-class supervision departments to view the information within their authority.
According to the modular design idea, different units and user groups can choose different subsystem modules according to their needs, so as to focus on their respective business scopes.
The overall architecture of the platform is shown in Figure 3 below7-1:
The overall platform is based on the distributed microservice architecture, adopts the BS structure, and has a hierarchical structure of technology platform, business platform and application platform to meet the changes in business logic and customer application requirements.
The platform has a clear and reasonable technical architecture plan to meet the technical layering requirements of the resource layer, service layer, and presentation layer.
The platform adopts the method of front-end and back-end separation to bring better experience effect.
The platform planning can complete the business requirements in the construction content, and has a clear modular architecture to reduce the coupling degree of each module and facilitate the independent deployment and upgrade of modules.
The integrated platform opens up the data from the bottom layer, the data is the same number and the same source, and the basic data is fully shared, and a large platform meets all the informatization of the smart construction site.
The platform achieves uninterrupted operation, large capacity, high stability and reliability, and is built on the basis of the existing information support system, follows and adheres to a high starting point and high requirements, and ensures that the platform reaches the leading level of technology in the corresponding fields in China.
The database management system has good data and index compression technology, and has a low space expansion rateUnder the condition that the hardware resources of the system allow, the response time to the database and structured unstructured complex queries can reach the sub-second level, and the efficiency does not decrease with the increase of the number of files, and the database scale is only limited by the hardware resources.
The platform is fully connected with the platform of the superior center, and has an open data interface.
The system supports the number of site users, meets the needs of municipal management, and reserves space for expansion.
