The design of distribution automation system based on industrial ethernet;

Analysis of distribution automation in urban areas;

Communication modes for distribution automation systems;

After an analysis and research of its counterparts at home and abroad, demonstration for instructing the course of automatic assembly production line of great variety was developed with practical engineering design taken into account.

This paper aims at the large aircraft and its structure characteristics,and by comparing the man assembly system with the machine assembly system and analyzing relation curves of automatic assembly and assembly cost,points out the meaning of automatic assembly technology which ensures long life,high efficiency and low cost of large aircraft structure,both in research and in manufacture.

One of the difficulties in visualized design is the automatic assembly.

Solution scheme to database management system in power distribution automation system;

Aiming at power distribution automation communication system to data transmission reliability and real-time etc require-ments,it is raised to use radio communication method to make up the insufficiency of traditional power distribution network automation system communications.

The basis of power distribution automation is the realization of feeder automation The scheme of sectionalizing and separating faults of feeder automation system based on CANbus is used to solve some key technical problems of the system.

A simple description of Distribution Automation System(DAS) and Feeder Automation(FA) is given in this paper.

Distribution automation System (DAS) needs communication which is reliable and effective, so that information and control signal can be transmitted among distribution control center, feeder automation substation and plenty of remote feeder terminal units.
