Problems solved by technology

[0003] The purpose of the present invention is to solve the above problems and provide a method for storing parameters of distribution network terminal equipment based on multi-area storage, which will not cause the problem of unusable parameters due to an abnormality in one memory, and effectively reduce the problem of electromagnetic interference and memory damage. Parameter abnormality caused by it, that is, no increase in system resources, ensuring correct storage of parameters, and increasing the time for normal operation of system equipment

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Distribution network terminal equipment generally consists of CPU, detection circuit module, storage module, power supply module and communication module. The storage module will use a large-capacity memory to record the data of the detection circuit module. The storage module will also have a dedicated parameter memory, as well as additional memory designed for other functional requirements, such as a memory for storing program codes to facilitate program updates. The storage module includes three storage areas, namely area 1, area 2 and area 3, and each storage area is relatively independent and serves as a backup for each other.

[0025] The distribution network terminal equipment selects ferroelectric FRAM as the main area 1 for parameter storage;

[0026] The CPU of the distribution network terminal equipment adopts the STM32 series microco...

Abstract

The invention discloses a multi-region storage based parameter storage method for a distribution network terminal device. A storage module comprises at least three or more storage regions which are regions 1-n respectively, wherein n is greater than or equal to 3. When the distribution network terminal device runs for the first time, default values of all parameters are stored in the storage regions; when being modified, the parameters are stored in the storage regions after being checked; when the distribution network terminal device runs normally, the parameters of all the storage regions are cyclically detected, and if all the storage regions have errors and the errors do not disappear after rechecking, functions related to the parameters are disabled; and as long as one correct storage region exists, the parameter of the correct storage region is stored in the error storage region, and if an error does not disappear after rechecking, a system reports the storage region with the error and enters a normal running state, so that the problem that the parameter cannot be used due to the fact that an exception occurs to one memory is solved.

Description

technical field [0001] The invention relates to the technical field of distribution network terminal equipment, in particular to a method for storing parameters of distribution network terminal equipment based on multi-region storage. Background technique [0002] With the development of smart distribution network technology, higher and higher requirements are put forward for the performance of power distribution terminal equipment. However, in the on-site operating environment, due to factors such as unexpected power outages and interference, some parameters in the equipment will be affected. , and the correctness of the parameters directly determines whether the terminal equipment of the distribution network can play the role of monitoring, detection and protection, and ultimately leads to the failure of the equipment to operate normally. The general design of the terminal detection equipment of the intelligent distribution network is based on the embedded platform, and th...
