Embodiment Construction
[0041] The present invention will be further described below in conjunction with embodiment.
[0042] A method for storing time-series data based on large redundancy, specifically comprising the following steps:
[0043] Step 1. The sensor sends time series data to the server, and the server uses an in-memory database (redis database is used in this embodiment) as a cache. The time series data in the memory database is called by the service platform and displayed to the real-time data monitoring terminal. Under normal circumstances, the data monitoring terminal only needs to monitor short-term data, and the real-time time-sharing data is stored in the redis database. In this embodiment, an identifier is assigned to each sensor, and the time-sharing data is cached with the date included.
[0044] Step 2. After the time-series data sent by the sensor reaches the set period of measurement and control time or completes the phased measurement task, the server stores the time-serie...
