Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 , 7 As shown in and 8, the present invention S01. collects data: several sensors on the RTU collect the data information of the surrounding environment, and the data information collected by each sensor is a sensor data set, and each sensor data set includes several independent data files, Only one field in the data information is saved in each independent data file, which is an index, collection time, collection data or reporting flag, that is, the independent data file is an index file, collection time file, collection data file or Report the mark bit file; using column storage will have an impact on the writing speed. In actual projects, the RTU can access dozens of sensors at most, and the number of concurrent data written at the same time per second generally does not exceed 10. Therefore The write performance is ...

Abstract

The invention relates to data processing, in particular to an RTU data storage method. The method comprises the following steps: S01, collecting data; S02, buffering data: reporting each piece of collected data information to a business platform, setting a reporting zone bit of current data information according to a reporting result and writing the reporting zone bit into memory, wherein each 1024 data of each independent data file is a data block, and compressing each data block after each data block is written into the memory; S03, writing data: writing compressed data blocks into a file system, clearing the memory and repeating the step S02. The biggest advantage of the RTU data storage method lies in extremely high storage utilization rate. Compared with an embedded database scheme, the occupied storage space is only 1 / 20 as much as that of a database. After compression is enabled, the space can be shrunk from 1 / 40 to 1 / 80.

Description

technical field [0001] The invention relates to a data processing method, in particular to an RTU data storage method. Background technique [0002] RTU is an IoT device that integrates collection and transmission. After reading the external sensor data, it transmits it to the remote service platform. Widely used in electric power gas meter reading, meteorology, environmental protection, intelligent buildings and other industries. In some industrial applications, the RTU is required to have a local storage function. The data collected by the sensor, in addition to being transmitted to the remote platform, also needs to be stored locally for retrieval and query. However, from the perspective of cost control, the RTU hardware performance configuration is generally low. For example, a certain RTU has a CPU frequency of 300MHZ and a built-in / external memory card capacity of 8GB-16GB, which is far lower than smart hardware devices such as tablets on the market. The data collect...
