11 HDP - High frequency
density and speed Data Platform construction
High frequency refers to sampling time, high density refers to space, and high speed refers to the speed of accessing the platform. 11.1
Traditional - Data Platform
Based on databases, it is basically in seconds. 11.2
High frequency - Data Platform
There is a huge market demand for secondary analysis and development based on high-resolution data, but the threshold is high. Currently, data analysis is mostly done in seconds, and upgrading the data platform to High Density Data Platform is an ideal choice. If the platform's rich analysis methods and close connection with business can be integrated with high-resolution data, it will definitely create a domestically unique high score and high density platform, achieving a sudden rise. 11.3 High Frequency and High Density - Data
Platform
As a transitional platform, it can store high-frequency and high-density data without requiring access speed. It is easy to build a conventional platform in combination with PDA. Advantages: There are no special requirements for platform hardware performance, which can remain unchanged, with almost no additional costs, minimal workload, and no technical bottlenecks. Disadvantage: There will be no improvement in access speed.

Speed - Data Platform
This is the ultimate goal, which can store high-frequency and high-density data, and the access speed requires a return result in seconds. All applications must establish a result time of 3 seconds, otherwise the user experience will be poor. For example, if a search command on Google, Baidu, or Taobao produces results in 10 seconds, it will be difficult to promote. These are civilian applications, and industrial high-frequency and high-density data platforms should have higher standards. For data at the second, minute, and meter levels, if it meets business requirements, it should still be retained. However, the platform performance has changed, and such applications can produce results in less than one second. The cost should be appropriate, the plan should be carefully selected, and the technology should be optimized. 11.5 Implementation method
The full installation of PDA in each project will lay a solid foundation for a high-resolution data platform, which can form centimeter level, millisecond level, or even microsecond level data platforms in the short term. By fully utilizing and exploring the super strong capabilities of PDAs that are very suitable for processing large amounts of data, it will form a strong competitive advantage in domestic and international markets. High resolution and high-density data platform is a practical requirement for data analysis. Once a high resolution and high-density high-speed data platform is formed, it will be able to establish technological advantages, and the threshold for a second level data platform is relatively low. As long as fully open PDAs are popularized in every project, such a platform will have a foundation and can be developed smoothly. 11.6 Cooperation with the outside world
High performance controllers
in For many years, our R&D
team has been dedicated to the exploration of communication protocol research
and development, field bus analysis, high-speed data acquisition, real-time
data compression, massive data storage, online data analysis, and other
technologies. We have devoted infinite energy and enthusiasm, worked
tirelessly, and finally achieved some breakthroughs. We hope to share and
encourage with everyone, and make some modest contributions to improving the
production and quality of industrial products, equipment testing, fault
diagnosis, Industry 4.0, and big data quality analysis in Some high-speed data collection systems in foreign countries are becoming increasingly closed, with layers of encryption. As a strategic partner, it is necessary to require unconditional open data interfaces. In order to significantly reduce the cost of high-frequency data collection, we have made unremitting efforts and launched major customer systems, annual package systems, etc., laying the foundation for the widespread popularity of PDAs. This way, the cost of each project can be basically ignored, and installing several sets of high-frequency data collection for each project will not be a problem, laying a solid foundation for high-resolution data platforms. PDA is only responsible for
basic data collection, storage, and analysis functions, and all subsequent
tasks are done by the platform, including rapid exchange, conversion,
storage, analysis, calculation, display, and interaction between the platform
and high-frequency data. PDA provides underlying support, which will be a
milestone and revolution for the data platform, with profound strategic
significance. We hope to shine a light on the construction of platforms in |
