In the field of industrial automation, data collection, storage, and analysis are fundamental to efficient decision-making and operations. AVEVA Historian (formerly Wonderware Historian), a leading industrial real-time database, focuses on collecting and storing high-fidelity historical process data. Meanwhile, TDengine, a high-performance database specifically designed for time-series data, excels in processing and analyzing large volumes of real-time and historical time-series data.
In the latest TDengine version 3.2.3.0, we have further enhanced the data integration capabilities by introducing a new connector aimed at integrating AVEVA Historian with TDengine. This article will explain the innovative approach of integrating historical and real-time data from AVEVA Historian into TDengine, and how this combination can significantly improve data utilization, creating a solid foundation for industrial innovation and promoting efficient development in industrial automation.
Current Industrial Time-Series Data Processing Solutions:
- Relational Databases (e.g., Oracle/MySQL)
- Low read/write performance when handling large volumes of time-series data.
- Poor distributed support; query speed slows down as data increases.
- Typically used in low-frequency monitoring scenarios and power SCADA historical databases.
- Traditional Industrial Real-Time Databases (e.g., PI System, AVEVA Historian)
- Effective in industrial data storage but outdated architecture with no distributed solutions; cannot scale horizontally.
- Dependent on environments like Windows; weak in data analysis and often closed systems.
- Mainly used in SCADA systems and production monitoring systems.
- NoSQL Databases (e.g., MongoDB, Cassandra)
- Poor real-time computation, slow query speed, high memory and CPU overhead, and lack of optimization for time-series data.
- Mainly used for unstructured data storage and web scraping data.
- Hadoop Big Data Platforms (e.g., HBase, Zookeeper, Redis, Flink/Spark)
- Support distributed processing but handle time-series data in an unstructured way with a complex architecture and high maintenance costs.
- Primarily used for general big data platforms and public opinion e-commerce big data.
In today’s industrial enterprises, there is a strong demand for innovative applications in critical scenarios like intelligent decision support, equipment fault prediction, product quality analysis and forecasting, intelligent manufacturing and digital twins, and energy management. These scenarios highlight the core value of industrial time-series big data in innovation. Industrial enterprises must adopt advanced solutions to accelerate innovation and achieve differentiation in a competitive market.
In industrial settings, multiple factories or workshops typically deploy independent SCADA/Historian systems, such as AVEVA Wonderware and PI systems, to manage real-time and historical data. This is a common practice in industrial automation, with data distributed across various on-site databases.
Advantages of Centralizing Time-Series Data:
Centralizing time-series data enhances overall data control, enabling enterprises to better utilize their data assets. Centralized data processing allows for global data visualization, inspiring business innovation and providing a means for quick validation. It helps enterprises better manage and analyze data, swiftly respond to insights, and make timely business decisions.
SCADA/Historian systems also offer data centralization solutions, which can meet some needs. However, they face challenges in supporting massive amounts of data points (sensors, devices, etc.), struggling to meet the demands of innovative applications that require extensive time-series data acquisition. When the data volume is very large, SCADA/Historian data consumption interfaces may perform poorly, experiencing high latency and even failing to retrieve the necessary datasets.
Addressing These Challenges:
To effectively address these challenges, the following optimizations are necessary:
- Utilize Existing Investments: Enterprises often already have multiple SCADA/Historian systems in place, representing significant investment. The solution must consider how to fully leverage existing systems to avoid redundant investments.
- Enhance Data Consumption Interfaces: Improve the capability of data interfaces to ensure fast, efficient data consumption even when dealing with large volumes.
- Reduce Latency: Enhance system performance to minimize data processing and retrieval latency, ensuring timely data acquisition.
- Integrate Real-Time and Historical Data: Integration can improve storage space utilization and provide a more complete data view for analysis and decision-making. Combining real-time and historical data supports more complex innovative applications like predictive maintenance, energy management, and operational optimization.
- Support Massive Data Points: Increase the system’s capacity to handle numerous data points to accommodate the growing demand for sensor data.
- Promote Innovation: Build an infrastructure that supports innovative applications, addressing the needs of new industrial applications like predictive maintenance, asset performance management, and energy efficiency optimization. This requires deeper data consumption, analysis, and faster processing.
TDengine, as a symplified time-series big data platform, offers high data writing and query performance, suitable for handling vast amounts of industrial time-series data. In addition to its core functionality of unifying real-time and historical time-series databases, it also provides message queues, event-driven stream processing, read-write caching, and multi-data source integration capabilities. TDengine provides a comprehensive solution for implementing the above optimizations.
