Problems solved by technology

[0003] At present, the data storage of embedded devices adopts erasable and programmable FLASH devices, so that the data will not be lost due to power failure, but this kind of FLASH has a service life, beyond the service life, embedded devices will not be able to erase the FALSH write, will result in data not being written or lost
[0004] Existing concentrators only use FALSH devices to simply store meter data, which has potential data security risks and data loss risks

Embodiment Construction

[0038] The present invention provides a complete program for the data stored in the concentrator, the program will save the data is encrypted, and adds the CRC check, so can guarantee the security of user data, but also to ensure the correctness of the data. At the same time, important data concentrator meter will be backed up against the original data is lost or destroyed, the concentrator can recover data in a timely manner.

[0039] The present invention will be described in more detail below with reference to the accompanying drawings. While a preferred embodiment of the present invention, however it should be understood that the present invention may be implemented in various forms and embodiments should not be set forth herein limits the accompanying drawings. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and the full scope of the invention convey the skill in the art.

Abstract

The invention discloses a concentrator data security management method, which comprises the following steps of: dividing a FLASH storage device of a concentrator into at least one data read-write partition and at least one data backup partition, and mounting an independent file system on each partition; when the concentrator runs, executing the following steps: collecting ammeter data; storing the electric meter data in an encrypted database; respectively storing the ammeter data to a data read-write partition and a data backup partition; and when the file system of the data read-write partition is abnormal and cannot be read and written, judging whether a set formatting condition is met or not, if so, selecting to restart the concentrator or formatting the data read-write partition and copying backup data in the data backup partition into the formatted data read-write partition, otherwise, restarting the collector. The integrity and the safety of the concentrator for storing the electric meter data are improved, and the data can be effectively recovered when the storage equipment is damaged.

Description

Technical field [0001] The present invention relates to the field of smart grid data acquisition, and more particularly, to a centralized data management security. Background technique [0002] In recent years, the rapid development of the smart grid, grid-scale growing more and more, concentrator collection of data, data management has become an important means of concentrator technology to maintain the grid. User data for the power companies, it is very important, as centralized data collection terminals, not only to save the meter collection data, and also need to maintain accuracy of the data, when the master of the meter data concentrator church be read , the need to ensure that the master station response data is correct and effective. [0003] Currently, embedded devices are used to store data erasable programmable FLASH device, so that data is not lost due to power failure, but this FLASH has a life beyond life, embedded devices will be unable to erase FALSH write, will r...
