Description
Technical field
The present invention relates to technical field of data processing, more particularly, to a kind of sensor time series data of hierarchical structure
Storage method and system.
Background technology
Time series database full name is time series databases.Time series databases are mainly used for referring to processing band time tag
The data of (changing according to the order of time, i.e. the time serializes), the data with time tag are also referred to as time series data.When
Between sequence data mainly by all types of monitorings in real time such as power industry, chemical industry, check and gather, produce with analytical equipments
Data, the typical feature of these industrial datas are：Generation frequency fast (each monitoring point can produce more datas in one second),
Depend critically upon acquisition time (each data is required to correspond to unique time), (conventional is real-time greatly for measuring point multiple data quantity
Monitoring system has thousands of monitoring point, and monitoring point all produces data each second, produces the data volume of tens GB daily).
With the popularization of technology of Internet of things and the development of sensor technology, industrial circle carries out measurement value sensor instant
Transmission, storage and the operation of inquiry and renewal are more universal and important.The sensor of industrial circle and its numerical value of generation have
Three features below：(1) data caused by sensor are a kind of time serieses being made of timestamp and sensor collection value
Data, these data usually carry out the storage and operation of data using sensor as least unit；(2) the sensing utensil of data is produced

Various (such as multiple sensors may belong to areal, same owner, same equipment)；Data carry out produced by sensor
During storage, these attribute informations also need to be recorded simultaneously；(3) when being operated to sensing data, user needs root
Carry out simply increase, inquiry, renewal, delete operation and complex operations in itself according to attribute sensor information or sensor.
Therefore, find a kind of suitable time series data storage method and carry out category that is simple, intuitively describing time series data complexity
Property information, and it is particularly critical conveniently by this expression way to the attribute information of these time series datas inquire about etc. operation.
The existing expression for time series data is typically attribute information scatteredization.InfluxDB, OpenTSDB etc. are more mature
The attribute information of time series data can be disassembled among the distinctive concept of its system in time series database.Such as have in InfluxDB
Three kinds of descending concepts, respectively measurement, label and domain, user is needed the attribute of time series data by balance during use
Information is discrete to be corresponded in these three concepts, then carries out the operation such as inquiring about by Property Name.Such expression way solves
The expression problem of a variety of attribute informations, can also support that the time series data for attribute information operates, but there is also one at the same time
A little problems：By the complete discretization of attribute information so that the relevance of original level concept is not expressed；It is not easy to carry out belong to more
Property inquiry combination；Enter gate threshold height.
