Problems solved by technology

Most of the existing data replay work is research on financial securities, user real-time recommendation and other services. These works do not involve the time series flow data collected by sensors, so they cannot be applied to industries that rely on sensors for data collection. , water conservancy, medical and other industries
Due to the lack of existing research, coupled with the unique time characteristics and structural characteristics of sensor flow data, it is still a challenge to perform smooth and stable playback

Embodiment Construction

[0032] Below in conjunction with specific embodiments, the present invention will be further illustrated, and it should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. The modifications all fall within the scope defined by the appended claims of this application.

[0033] like figure 1 As shown, a data playback system for sensor stream data includes: a historical data storage layer, a database connection layer, a data playback execution layer and a playback data display layer.

[0034] Historical data storage layer, the system uses the time series database Apache IoTDB to store historical sensor data. IoTDB provides the replay system with all time series data that can be replayed, and is deployed on a virtual machine cluster. All virtual machines in the cluster are configured exactly the same . In the time series database Apache IoTDB, data is divided into multiple time series accordi...

Abstract

The invention discloses a sensor stream data-oriented data playback system and method. The system comprises a historical data storage layer, a database connection layer, a data playback execution layer and a playback data display layer which are sequentially arranged from bottom to top. The data playback method comprises the following steps: (1) installing and configuring a time sequence database Apache IoTDB; (2) connecting a database and acquiring replay data by using a database connection pool and a thread pool; (3) constructing a concurrent buffer pool to replay historical data; and (4) integrating the data display interface and the concurrent buffer pool module to realize a data replay Web system, and enabling a user to select data to be replayed and set specific parameters through a system page to realize a smooth and flexible data replay effect.

Description

technical field [0001] The invention relates to a data playback system and method for sensor stream data, in particular to a data playback system for hydrology and water quality sensor stream data and a construction method thereof, belonging to the technical field of software development and sensor data processing. Background technique [0002] With the development of the Internet of Things and big data technology, sensors are increasingly used in all aspects of social life, and the data collected by various sensors contains more and more information. Since most of the data collected by sensors are real-time data with time stamps, the amount of data is huge, which increases the difficulty of real-time analysis. In order to solve the insufficiency of real-time data analysis in the face of massive sensor data, data replay technology can be applied to this. Data replay refers to the process of streaming historical data to top applications, and it is widely used in performance ...
