Abstract

The invention provides a method for implementing shared memory of a power quality management system, including: S1, data initialization setting, and completing the basic configuration of various data in the power quality management system in the database; S2, creating a shared memory library; S3, creating a shared memory process to realize the memory sharing of the power quality management system. The implementation method of the shared memory of the power quality management system described in the present invention directly realizes the shared memory file mapping without bottom layer settings, reduces the occurrence of memory read and write errors in the power quality management system, and ensures the continuous and stable operation of the shared memory of the power quality management system.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a method for realizing a shared memory of a power quality management system. Background technique [0002] With the rapid development of the railway industry and the ever-changing science and technology, the railway industry has higher requirements for the power quality of the power supply system. It is necessary to provide a professional power quality management system to monitor the power operation of the electrical equipment used in the substation. This requires a high reliability of the power quality management system. Each process of the system is the basic unit of the system for resource allocation and scheduling, and each process needs a shared data space for data interaction. The shared data space provides necessary data support for the normal operation of each functional module of the system. The shared data space in the power quality manage...
