Extensible multifunctional control system

Abstract

The invention discloses an extensible multifunctional control system, which comprises a multifunctional controller consisting of a tension controller module, a correction controller module and a temperature controller module, a plurality of tension sensors, correction sensors and temperature sensors and a plurality of tension execution mechanism controllers, correction execution mechanism controllers and temperature execution mechanism controllers. The tension controller module of the multifunctional controller is connected with a group of tension sensors and tension execution mechanism controllers through a bus to form a path of tension control system, the correction controller module of the multifunctional controller is connected with a group of correction sensors and correction execution mechanism controllers through a bus to form a path of correction control system, the temperature controller module of the multifunctional controller is connected with a group of temperature sensors and temperature execution mechanism controllers through a bus to form a path of temperature control system, and the multifunctional controller of the system is connected with multiple paths of tension control systems, correction control systems and temperature control systems by buses.

Description

Technical field: [0001] The invention relates to a controller integrating deviation correction control, constant tension control and temperature control, in particular to an expandable multifunctional control system. Background technique: [0002] With the need to improve the production process brought about by the competition of end products and the factory's need to reduce the reliance on the skill level of operators, more and more new production equipment uses various types of automatic control instruments. [0003] In printing, packaging, anti-counterfeiting label equipment and textile equipment, constant tension controllers, deviation correction controllers, and temperature controllers can be seen everywhere. However, the existing products are basically single-function and single-channel control. If there is a need for multi-function multi-channel control, the equipment manufacturer will be under greater cost pressure. The core processor of the existing controller is s...

Problems solved by technology

However, the existing products are basically based on single-function, single-channel control. If there is a need for multi-function multi-channel control, the cost pressure of equipment manufacturers will be greater

The core processor of the existing controller is still based on the old 8051 single-chip microcomputer. When there is a demand for a very fast response speed, the existing controller is often unusable.

[0004] In addition, the existing constant tension controllers, deviation correction controllers, and temperature controllers cannot support bus control. Each control needs to be connected with at least four wires, and at most fifteen or sixteen wires. In addition, some devices have It is 20-30 meters long, which is a big waste of materials, and it costs a lot of money from commissioning to post-maintenance; secondly, due to the production process problems of existing equipment manufacturers, many sensor lines are currently inferior to high-power lines. Mixed walk, the signal interference problem often makes all kinds of controllers unable to achieve the expected effect

[0005] On the other hand, the existing deviation correction controllers, constant tension controllers, and temperature controllers cannot expand the man-machine interface. The existing controllers are either installed in the main control cabinet or near the equipment operating station. It is impossible to take care of both heads. Two people are often required for equipment debugging and maintenance. However, some equipment is 20-30 meters long, and there are certain safety hazards in the operation of the equipment.
