4 HDS - open time
series high frequency Historical database
The full name of a time series database is a time series database, which is mainly used to process data with time labels (changing in chronological order, i.e. time serialization). Data with time labels is also known as time series data. Time series data is mainly collected and generated by various types of real-time monitoring, inspection, and analysis equipment in the metallurgical, power, chemical, meteorological, and geographic information industries. The typical characteristics of these industrial data are: fast generation frequency (each monitoring point can generate multiple pieces of data within one second), severe dependence on collection time (each piece of data requires a unique time) Multiple monitoring points have a large amount of information (conventional real-time monitoring systems have thousands of monitoring points, which generate data every second and tens of GB of data every day). Commonly used temporal databases include InfluxDB, KDb+, Prometheus, Graphite, RRDtool, TimescaleDB, Apache Druid, Fauna, OpenTSDB, GridDB, DolphinDB, KairosDB, etc. Open high frequency time series Historical Database Server stores PDA millisecond level high-frequency data into the temporal database and can access it through SQL statements.
Figure 4.1 InfluxDB Time Series Database System Files dbUpgradeTSA.exe~dbUpgradeTSL.exe is located in the PDA or HDServer directory. It converts the data files collected by PDA to. csv files supported by InfluxDB at the original sampling frequency or frequency reduction losslessly, and imports them offline in bulk into InfluxDB. The table structure is identical to the configuration of Config.csv.
Figure 4.2 Upgrading PDA Configuration to InfluxDB dbUpgradeTS has multiple processes, each converting several connections to ensure that the write timing database can keep up with the speed of PDA generating data files, Each process scans PDA data files every 2 minutes.
Figure 4.3 Batch Import of PDA Data to InfluxDB Cancel the quick editing mode and insertion mode in the Console window of the influx service program to avoid input interference.
