Abstract
The invention relates to a control system for speed chains of paper machines. The system consists of a touch screen 1, a PLC module 2, a frequency converter 3, a control cabinet 4, an operation desk 5, a contactor 6, an air switch 7, a PLC program 8 and a fieldbus 9. The system is mainly advantaged in that the powerful software function can reduce the engineering time, improve the intelligentized degree of the system, and realize the complex control function.
Description
Technical field
The present invention relates to the control system of a kind of paper machine speed chain.
Background technology
In paper making equipment, transmission is required to meet constant speed difference, given speed chain, keeps linear velocity to synchronize, compared with general paper machine, it is desirable to precision is higher, more stable, response faster. Therefore, Synchronization Design is the pith that Paper Machine Drive controls.Speed ChainThe common practice is to adopt person-computer union, Programmable Logic Controller to control converter by (4 ~ 20mA) analog quantity or communication mode to realize branch's driving control system.
Summary of the invention
It is an object of the invention to provide the research and development of a kind of Fieldbus Based paper machine multi-drive synchronization drive system, improve the reliability of drive system and the precision of control, enhance the capacity of resisting disturbance of system. Utilizing fieldbus to make each equipment of system have ability to communicate, form network system, simultaneously powerful software function can shorten engineering time, improves the intelligence degree of system, it is achieved complicated control function.
For achieving the above object, the technical solution used in the present invention is: the present invention relates to the control system of a kind of paper machine speed chain, open 7 including touch screen 1, PLC module 2, converter 3, switch board 4, operating board 5, catalyst 6, sky, PLC program 8, fieldbus 9 form, it is characterized in that the control system of described a kind of paper machine speed chain makes each equipment of system have ability to communicate by fieldbus 9, form network system.
The advantage of the present invention is mainly reflected in:
Powerful software function can shorten engineering time, improves the intelligence degree of system, it is achieved complicated control function.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the control system of a kind of paper machine speed chain.
1 touch screen 2-PLC module 3-converter 4-switch board 5-operating board 6-catalyst 7-sky opens 8-PLC program 9-fieldbus.
Detailed description of the invention explanation
The work process of the control system of a kind of paper machine speed chain is told about below in conjunction with Fig. 1:
Speed ChainThe common practice is to adopt person-computer union 1, PLC module 2 to control converter 3 by (4 ~ 20mA) analog quantity or communication mode to realize branch's driving control system. Wherein touch screen 1 is as input equipment, the instruction of operator is sent to PLC module 2, completed and the gear ratio of each branch according to total speed by PLC module 2, calculate the rotating speed of each motor, and calculate the operating frequency of each motor accordingly, the speed of each branch converter 3 is controlled by I/O mouth, each variable-frequency governor drive motor is made to operate, in converter work process, the data such as its running voltage, electric current, rotating speed send PLC module 2 to by PORT COM, and converter more than 3 running parameter just can show on the touchscreen in real time.
Based on the paper machine multi-drive synchronization drive system of fieldbus 9, improve the reliability of drive system and the precision of control, enhance the capacity of resisting disturbance of system. Utilizing fieldbus 9 to make each equipment of system have ability to communicate, form network system, simultaneously powerful software function can shorten engineering time, improves the intelligence degree of system.
