Abstract

A process and control system are provided for controlling a combination of spinning mill machines. The system includes the process of exchanging operational data and measured values between the machines on a plurality of different communication levels which are arranged in a hierarchy. The same communication protocol is used on all of the communication levels to improve the speed and ease of control of the combination of spinning mill machines.

Claims

1. A control system for a group of spinning mill machines connected in combination for carrying out coordinated spinning operations, said system comprising:

a plurality of hierarchy communication levels, a lowest said communication level comprising at least one multiprocessor bus backplane assigned to each of said spinning mill machines, each said bus backplane comprising a plurality of deterministic microprocessors connected thereto for carrying out deterministic tasks associated with said respective spinning mill machine;

a next higher communication level, said next higher communication level comprising a local bus connecting together said multiprocessor backplanes;

a common deterministic data communications protocol for said multiprocessor backplanes and said local bus so that multiprocessors of each said backplane and different said backplanes can communicate bi-directionally with said deterministic data communications protocol;

said local bus coupled to a higher superimposed communication level which includes a host control system for said entire group of spinning mill machines, said local bus and said higher superimposed communication level coupled together through a common network communications protocol.

2. The system as in claim 1, wherein each said bus backplane comprises a multilayer board having a plurality of plug-in points for components.

3. The system as in claim 2, wherein at least one spinning machine control system and one yarn monitoring system are plugged-in as components of said bus backplane.

4. The system as in claim 1, wherein said next higher communication level and said higher superimposed communication level are network oriented, and further comprising a circuit for coupling of measured values and commands on said network-oriented levels.

5. The system as in claim 1, wherein said spinning mill machines include spinning machines having a plurality of spinning stations.

6. The system as in claim 1, further comprising a plurality of said local busses, each said local bus corresponding to a machine group, said system further comprising a plurality of routers coupling said local busses to said higher superimposed communication level for control of all of said machine groups from said higher superimposed communication level.
