Embodiment 1

[0090] This embodiment provides a method for implementing lightweight model data loading and storage management of an embedded device. The method mainly includes the following steps:

[0091] 1) Definition of lightweight model data storage format, including file header format definition, data table header format definition, and data table custom data format definition;

[0092] 2) Customization and loading management of lightweight model files;

[0093] 3) Lightweight model file memory space optimizes storage management.

[0094] The definition of the lightweight model data storage format in the step 1) is as follows:

[0095] A. Lightweight model data file header format definition;

[0096] Lightweight model data file header information structure, as attached image 3 As shown in the schematic diagram, it is a necessary component for loading and storing management of model data files; among them, the file header structure includes the following fields (each field is stored...

Embodiment 2

[0121] This embodiment provides a data management method with a common format, compact structure, and simple loading and storage operations. Through the modeling and operation handle management of file header information, data table header information, and custom data table information, the model data is completed. Load storage and fast access operations; through self-describing cyclic redundancy check of model data customization and complete model data, the flexibility, integrity and reliability of model data are guaranteed; the process flow of the model data management method of the present invention is as follows: Figure 5 Model data loading process and Figure 6 The schematic diagram of model data rapid positioning is shown in the figure, and the specific implementation process is as follows:

[0122] 1. Model data format and creation of storage management handle

[0123] Create a management storage handle based on the custom model data format and the size of the memory ...

Abstract

The invention discloses an embedded device model data management method and device, and the method comprises the steps: loading a model data file which comprises file header information, a plurality of pieces of data table data and table header information in one-to-one correspondence with all data tables, and the file header information comprises initial table header deviation, the number of table headers, and the total length of all data table data; determining the position and the length of each header according to the initial header offset and the number of headers in the file header information; determining corresponding header information according to the position and length of each header; determining a reserved memory space and a memory model corresponding to the reserved memory space according to the file header information and the header information, wherein the memory model comprises a one-to-one correspondence relationship between data table data and a memory address; and storing the corresponding data table data to the corresponding memory address according to the header information of each table. The problems of storage, sharing, quick loading and conversion of modeldata between embedded devices or between the device and a computer are solved, and the storage efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for managing lightweight model data of an embedded device. Background technique [0002] Embedded systems especially involve embedded devices in the field of relay protection automation in power engineering, which have very high requirements for system reliability, speed, flexibility and versatility, but are controlled by hardware, general memory and storage The space will not be very large. At present, when an embedded device stores device model data, it usually pre-allocates storage space according to the number and type of device data. If the actual number of data or the size of the data is smaller than the size of the reserved space, the above method is likely to cause waste of storage space. The demand for reliable storage, fast access, and flexible generalization of device model data is increasingly urgent, especially in the exchange and conver...
