Title    Energy acquisition system for digital   manufacturing  workshop                             

Abstract With the rapid development of computer technology and the concept of digital workshop proposed, manufacturing is developing towards intelligence, information, integration。 Because of the complexity of the manufacturing technology, real-time data acquisition has been a bottleneck in the production of enterprises, it is eager to solve the problem that how to obtain the electricity situation with safety and quality。

According to the summary of the digital manufacturing workshop and the analysis of the connotation of the digital workshop, this thesis gives needs analysis of energy collection for digital manufacturing plant and put forward the overall design of the digital manufacturing plant energy collection system。 On this basis, combined with the existing smart meters and workshop profibus technology, this thesis not only designs and develops the energy management network system and interface application for digital plant, but also researches the RS485/Modbus communication protocol。 By using 。NET environment and the C# programming language it completed the development of the digital workshop energy management software system which has many functions such as usage analysis and power acquisition based on the task management and the station。 The development of digital manufacturing workshop for energy collection system will help enterprises to promote building digital workshop and saving energy and efficiency。
