1. Project background

In 2016, the national big data project jointly declared by Yakong Technology was approved by the National Development and Reform Commission. This project is the first batch of supporting projects for the major national big data development projects. Yakong Technology is responsible for the construction of the IoT perception platform in the project. The solution is based on the needs of shield construction business to build a set of industrial IoT platforms suitable for engineering construction (mainly shield engineering), and the platform has a cloud-side-end system architecture , It has the capabilities of protocol analysis, data processing, data standardization, remote management, and remote operation and maintenance. It can quickly develop and generate data collection application systems in various application scenarios, which are easy to use, easy to maintain, scalable, and high-safety, and finally achieve the goal of having data on the entire big data project platform.

2. Implementation content

Figure 1 Overall architecture of the platform

The distributed collection terminal mainly provides data collection services, converts various protocols into a standard unified interface, and releases data to the edge. In addition, in order to ensure the stability of remote operation and maintenance and the system, the acquisition terminal provides a remote diagnosis/maintenance interface and a software watchdog.

The edge end is mainly used to realize data aggregation, cleaning, calculation and standardization, conduct data consistency review and verification, filter invalid data and deal with missing data. To facilitate user-defined calculations, a script calculation engine interface is provided.

The cloud platform server is mainly used for user management, authorization management, project management, deployment management, edge management, collection management, remote operation and maintenance, etc., while providing an interface for data exchange with other platforms.

2.1 Collecting terminal function module

The collection terminal adopts a distributed deployment method, supports multiple communication links to access the platform server, including wired network, 4G, Wifi, etc., and supports high-frequency collection.

This part includes related device driver component library, device connection management, collection mode management and collection project management. Supports fixed and configurable conversion modes such as linear conversion, non-linear table conversion, square root conversion, direct accumulation, difference accumulation, and digital conversion of files;

The construction site uses the collection terminal application to realize the construction site shield machine, battery car, total station, level, water meter, electricity meter, rubber tube segment car, environmental monitoring equipment, check-in gate, floor scale, personnel positioning, mixing station and gantry crane Data collection of related equipment;

2.2 Edge function module

As the data sub-nodes of the cloud platform, the edge end undertakes the tasks of data cleaning and edge end data calculation to relieve the pressure of cloud platform big data services. This module provides a script calculation engine that can run custom scripts. The script supports logic operations, formula calculations, and data calculation related algorithms. Interact with the database, can call third-party modules, on-demand calculations, etc.; realize data analysis and modeling capabilities, calculate and process massive data in the enterprise, from simple calculations to complex algorithms, and finally realize data application, analysis and deep mining .

Through the edge application, the standardization of shield machine operating data and the cleaning of invalid data when the equipment is stopped, the conversion of the gear and speed of the gantry crane, the statistical analysis of the water and electricity meters by ring, day, week, and month, and many business scenarios Data analysis and mining applications.

2.3 Server function module

The server-side management configuration module provides management functions for the collection side and the edge side, including login authority management, authorization management, project management, deployment management, edge side management, collection side management, remote operation and maintenance, and provides full configuration development functions. Rapid development of BS client engineering and mobile app applications, through drag-and-drop, visual development; no need for professional programmers, industrial people can develop, operate and maintain independently through simple training, which greatly reduces the development cycle and shortens the development cycle by 30%;

Through this module, the full configuration mode realizes the realization of shield machine, battery car, total station, level, water meter, electric meter, rubber tube car, environmental monitoring equipment, check-in gate, floor scale, personnel positioning, mixing station and gantry crane Remote monitoring of related equipment.

3. The core value of the program

1. Realize the data collection of shield machine, battery car, total station, level gauge, water meter, electric meter, rubber tube car, environmental monitoring equipment, check-in gate, floor scale, personnel positioning, mixing station and gantry crane related equipment , Based on business needs, conduct data mining and analysis on various equipment, and can quickly configure business interfaces.

2. The platform realizes the "full configuration" technology in the industry, without the need for professional programmers, a wide range of industrial people can independently develop solutions according to their needs through simple training. Realize the industry's "model" technology (data model, calculation model, graphic model), and the workload of engineering development and maintenance is subvertedly reduced to 30%-70% of the original, and it can truly change on demand.

3. Realize the interconnection of all aspects of enterprise management, promote the migration of construction enterprises to the Internet, and improve the level of networked collaborative production. Ultimately, it will greatly improve production and operation efficiency, reduce enterprise operating costs, and enhance enterprise profitability and market core competitiveness.

4. It has laid a solid foundation for mining big data technology in the construction industry, and promoted the wider and deeper application of big data in the construction industry, thereby promoting the optimization and upgrading of the industry chain, and leading the construction industry from informatization and intelligence to wisdom Transformation will bring new inventions and new services to the construction industry to change the construction environment, technical means, and management methods.
