Intelligent concentrator and data processing method taking measurement point as tag

Abstract

The invention provides an intelligent concentrator. The intelligent concentrator comprises a controller, a cache unit, a real-time data receiving module connected with the controller, a real-time message queue data processing module, a real-time union data processing module, a real-time data storage module and a FLASH memory, wherein the real-time data receiving module, the real-time message queue data processing module, the real-time union data processing module and the real-time data storage module are connected in sequence; and the cache unit comprises a message queue data cache region, a union structure body cache region and a FLASH memory data cache region. The invention furthermore provides a data processing method taking the intelligent concentrator as a tag. According to the intelligent concentrator and the data processing method, the program efficiency of the intelligent concentrator can be effectively improved, the data security can be enhanced, and the service life of a FLASH memory chip can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electric energy metering instruments, in particular to an intelligent concentrator and a data processing method with measurement points as labels. Background technique [0002] The early electric energy meter had a single function and was only used as an electric energy measuring instrument, and the electric energy value could only be copied manually. With the development of electronic technology, electronic watt-hour meters have been used more and more widely, with greatly reduced volume, greatly enhanced reliability and accuracy. At the same time, the energy meter has more and stronger functions, so that the host computer can remotely read the data and set the function of the energy meter. In this context, the intelligent concentrator came into being, and it has been greatly affirmed by the market once it was launched. As a data collection instrument between the upper computer and the electric meter, ...

AI Technical Summary

Problems solved by technology

The traditional method has disadvantages such as low efficiency, low data security, too many reads and writes of the FLASH memory chip, and short life. This command will be discarded when there are three commands. At the same time, the block data of the FLASH memory chip will be repeatedly erased and overwritten in sequence when storing data.
