Fault priority control method for spinning unit of fully automatic intelligent spinning machine

Abstract

The invention provides a priority control method for the failure of a spinning unit of a fully automatic intelligent spinning machine. The method for priority control of spinning unit faults of fully automatic intelligent spinning machines includes a headstock and a plurality of spinning units, the headstock includes a headstock bus control ECU, the spinning unit includes a spinning unit ECU, the The headstock bus control ECU is connected with the spinning unit ECU through RS485 duplex communication. The invention provides a method for priority control of the spinning unit failure of the fully automatic intelligent spinning machine with simple connection structure, less network wiring, and adopts the traditional RS485 duplex communication mode, which is low in cost and reliable.

Description

technical field [0001] The invention belongs to the technical field of automatic control of spinning machines, and in particular relates to a fault priority control method for a spinning unit of a fully automatic intelligent spinning machine. Background technique [0002] Fully automatic intelligent (air-jet vortex) spinning machine is a highly automated and intelligent spinning equipment that integrates the functions of roving frame, spinning frame and automatic winder, and is at the leading level of contemporary spinning technology. Accurate and reliable discrimination (16 to 120) of the fault category of the spinning unit, orderly transmission of spinning unit fault information, is one of the key technologies of the fully automatic intelligent spinning machine. At present, most of the domestic use Ethernet to control multiple spinning units, but in actual use, there are the following problems: first, the headstock controller detects all 80 spinning unit channels in a timi...

AI Technical Summary

Problems solved by technology

At present, most of the domestic use Ethernet to control multiple spinning units, but in actual use, there are the following problems: first, the headstock controller detects all 80 spinning unit channels in a timing sequence, wasting the CPU resources of the headstock; The unit is responsible for normal spinning, and it needs to report fault information with the headstock regularly, which wastes the CPU resources of the spinning unit; third, there are many channels and connections, and the machine is easy to be blocked; Low efficiency; Fifth, the OSI standard 7-layer network model is used to process the data link, which has a large amount of data and takes a long time to process failures

The above defects restrict the fault handling rate of the spinning machine, so it is necessary to propose an improvement
