Abstract

The invention provides a synchronization method of multi-computer communication in shared memory of a power quality management system. The method comprises the steps of S1, packaging communication messages of data to be updated and shared; 2, creating a synchronizer thread; Realizing synchronous communication of communication messages among multiple computers by a synchronizer; S3, registering themulticast service; S4, sharing the communication message to other servers through the synchronizer and the multicast service; S5, after receiving the communication message, other servers analyzing the communication message and updating the data. The invention realizes the serialization of the shared memory table record structure through the ACE structure directly, there is no need to compile andset the bottom code, which reduces the error of reading and writing in shared memory of power quality management system, and increases the flexibility of shared memory data structure through the serialization synchronization message of shared memory table record structure.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a multi-machine communication synchronization method for a shared memory of a power quality management system. Background technique [0002] With the development of the urban rail transit industry, the power quality management system based on the subway industry is getting larger and larger, and a single server is increasingly unable to meet the growing demand for data collection, data sorting, data forwarding and data storage of subway line electrical equipment. need. With the development of distributed computing technology, the above problems can be dealt with by multiple machines to complete the work of the power quality management system. [0003] In the multi-machine power quality management system, an important core part is to realize the synchronization between multi-machine shared memory. In the distributed computing of the power quality mana...
