Data reading and writing method based on load balancing mode

Abstract

The invention provides a data reading and writing method based on a load balancing mode, which belongs to the field of instrument data management, and is used to control the data reading and writing process of the pulse storage area, including reading according to the storage times in the pulse storage area and then obtaining the stored gas volume , process the storage times of the pulse storage area according to the stored gas volume, and judge the current state of the storage medium according to the operation times in the main storage area and backup storage area in the pulse storage area, and stop the data read and write operation after the number of operations exceeds the operation threshold , so as to protect the reliability of the data stored in the storage medium, and in the process of reading and writing data in the main storage area, determine whether to switch the operation object of the read and write operation by monitoring the number of operations between the current main storage area and the backup storage area, thereby Realize load balancing control in the process of data read and write operations, ensure gas statistics can be carried out normally, and protect the rights and interests of both enterprises and users.

Description

technical field [0001] The invention belongs to the field of gas data management, in particular to a data reading and writing method based on a load balancing mode. Background technique [0002] In order to ensure that the user data is not lost after the gas meter battery is powered off, a non-volatile memory is used to store important gas meter data. The storage method is to store specific gas meter parameters at a fixed address, and initiate a storage request to the memory every time the power is turned off. [0003] The current memory uses a single-address model to store gas meter parameters. Once the storage medium is damaged or fails to read and write, the gas meter storage parameters will be lost, making the gas supply unable to be counted normally, resulting in the failure of normal communication between residents and gas supply companies. The data accounting has affected the normal income. Contents of the invention [0004] In order to solve the shortcomings and ...
