Abstract

The invention discloses a distributed real-time data interaction method irrelevant to position, which is realized through a service system formed by at least more than one node networked in the same network. The method comprises the following steps that application service software running on the node sends a data request for running a service object which does not exist in the node; after receiving the data request, the intelligent sensing service software running on the node forms a request for inquiring the position of the business object and sends out the request; the intelligent sensing service software running on the rest nodes receives a request for inquiring the position of the business object; whether the business object exists in the node or not is judged, if yes, the query request of the position of the business object is responded by the intelligent sensing service software of the node where the business object is located, request information is sent to the node, and the intelligent sensing service software responds; and the application service software of the node and the application service software of the node where the business object is located establish a real-time data channel to realize real-time data communication.

Description

technical field

[0001] The present invention relates to the fields of distributed system, SCADA system, data processing technology, etc., specifically, a distributed real-time data interaction method irrelevant to location. Background technique

[0002] A distributed system is a software system built on the network, with a high degree of cohesion and transparency; in a distributed system, a group of independent computers form a unified whole when presented to users, as if it is a system like. Data Acquisition and Monitoring Control System (SCADA system) is a common application system in distributed real-time processing systems, and it is a distributed real-time processing system with high performance requirements; SCADA engineering application projects have long implementation process and configuration modification Frequent operations, in the real-time process of the project, with the continuous expansion of the system scale, the system network changes frequently, and the n...
