Novel communication method based on intelligent protocol conversion apparatus

Abstract

A novel communication method based on an intelligent protocol conversion apparatus is provided. The intelligent protocol conversion apparatus id disposed in an intelligent substation. The communication method is applied to a control system of the intelligent substation. The control system comprises n substation control nodes, m ZigBee regional base stations, a mobile communication base station and a substation control center. The n substation control nodes are positioned in all substations, wherein devices are connected by using RS-232 / rs-485 buses; adjacent nodes realizes a wireless Mesh ad hoc communication network through the ZigBee technology and exchange substation data in real time. Every ZigBee region substation is in remote connection with the substation control center through the mobile communication base station by using GPRS / CDMA data transmission equipment. Respectively, m is an integral ranging from 1 to 100 and n is an integral ranging from 2 to 256. In the system, the advanced ZigBee short-distance wireless communication technology is organically combined with modern intelligent network technology, and a self-coordination intelligent distributed control algorithm is adopted as the control method, and thus the optimal substation control effect can be realized.

Description

technical field [0001] The invention relates to the technical field of intelligent substation control, in particular to an intelligent protocol conversion device based on a wireless Mesh ad hoc network and a method for applying it to substation control. Background technique [0002] In order to reduce the pressure on the substation network, it is imperative to upgrade the existing substation control equipment to be networked and intelligent, and to seek a high-efficiency, low-cost, stable and reliable solution is the primary consideration in the equipment upgrade The problem. ZigBee (Zigbee) technology is an open communication standard for wireless networking of sensors and actuators specially formulated for monitoring and control application scenarios. It has the advantages of low power consumption and cost, flexible and simple networking, large network capacity and easy expansion. The data of each substation needs to be sent to the substation control center for unified de...

AI Technical Summary

Problems solved by technology

The data of each substation needs to be sent to the substation control center for unified decision-making. Therefore, the overall robustness and fault tolerance of the above-mentioned substation control system is not high, and the degree of intelligence is low. Once a failure occurs in a certain link of the centralized communication and control equipment, it will seriously Affect the actual performance of the system
