Problems solved by technology

However, in a working cycle of each actuator, the energy demand of different stages varies greatly, and the energy demand of the actual processing process is greater than that of other auxiliary stages, resulting in a low degree of matching between energy supply and load demand. , resulting in a large amount of energy loss in the production line
[0003] In addition, for each machining process, its part profile depends on the previous process and affects the profile of the next process, so it is very difficult to reduce energy consumption by changing the machining process

Abstract

The invention discloses an energy servitization system of a multi-machine production line and a control method, the system is composed of a driving system, an execution device, an energy supply bus and a controller, and energy is used as a service to be provided for a task requiring energy in the production line with high energy efficiency; all machines in a production line are reorganized to formthree types of controllable entities including a driving system, an energy supply bus and an execution device; a control center is provided; in the working process, when an execution device starts toprocess a corresponding task stage, an energy demand is provided, a control system responds to the demand, a sub-driving system which is in an idle state and can complete the working stage with highenergy efficiency is selected to provide energy service for the corresponding execution device through an energy supply bus, and the energy efficiency of a multi-machine production line is improved.

Description

technical field [0001] The invention relates to the field of multi-machine production line processing, in particular to an energy service system and method for a multi-machine production line. Background technique [0002] The production line has the advantages of high production efficiency, can complete multiple processes or even all processes of a part, and is widely used in the manufacturing industry. The execution devices on the production line complete the production tasks one by one, realizing the continuous processing of multiple different processes. However, in a working cycle of each actuator, the energy demand of different stages is quite different, and the energy demand of the actual processing process is greater than that of other auxiliary stages, resulting in a low degree of matching between energy supply and load demand. , resulting in a large amount of energy loss in the production line. [0003] In addition, for each machining process, its part profile dep...
