Specific embodiment:
The invention discloses a kind of methods for carrying out second control system transformation to old milling train, on the basis of first class control system
It is upper to increase the level two formed by a secondary server and at least two second level clients, and two systems pass through Ethernet
Data exchange is carried out, and the sub-control system in first class control system is transformed, sub-control system transform each control as
In the automatic exchange of the automatic data collection of system and integration and manual handling equipment, transmission control and thickness control operation
The detection of the temperature of addition pair, and formation temperature closed-loop control, pass through between secondary server and at least two second level clients
Wirelessly or non-wirelessly form tree topology.
The application is described in detail below with reference to the specific embodiment being transformed to old milling train.
Increase level two on the basis of first class control system, level two is ground by efficient rolling country research center
Hair, You Yitai secondary server and several second level groups of clients are at passing through Ethernet and first class control system carries out data
Exchange；And the sub-control system in first class control system is transformed, sub-control system transform the number of each control system as
According to automatic collection and integration and the automatic exchange of manual handling equipment.
Its specific adaptation step is as follows:
Originally there are two the control systems of producer to form for roughing control system, is that Tianjin day passes and the female thickness in Shanghai, Tianjin day respectively
The control system of biography is responsible for transmission and the movement at some valve stations, the female thick use in Shanghai using Siemens's S7-414-2 controller
Be that the control system of four Siemens S7412-1 is responsible for thickness control system, the data exchange of Liang Ge company is inconvenient, and there is controls
Precision processed is low, and thickness fluctuation is big, unstable product quality.
The control system in efficient rolling country research center is used after transformation, this system is using Siemens's highest level
Control system TDC, have many advantages, such as speed of service height, the big control precision of data collection capacity is high.
The position sensor at scene is transformed；Control system is using scorching exaggerated external superseded after originally
Differential transformer type displacement transducer, this sensor are easy to be done by other signals at scene using analog interface
Disturb, in addition volume is big, and precision is low, due to be outer sensor must using two, and increase fault point and maintenance at
This.
Using U.S.'s MTS position sensor after upgrading, Magnetic Sensor uses SSI digital interface, interface tool
There are strong antijamming capability, fast response time, in addition also has the advantages that small in size with high accuracy.
Transformation to live bending system；The roller of original system can only realize letter using proportioning valve, manual adjustment
Single Strip Shape Control, due to being that there is for manual control is reconciled not in time, low-response, degree of regulation is low, each teams and groups
The phenomenon that controlling unstable product quality caused by the difference of gimmick, the control for realizing convexity of also having no idea.
Add second level to issue automatically using the higher faster servo valve of response of precision after transformation, and carries out closed loop with profile gauge
Control solves an edition type, the variety of problems that convexity is generated by the control gimmick difference of people.
Transformation to the control of original valve station；Control system originally is using central controlled scheme, this control system
There is unwrapping wire distance, sensor signal is easy to be disturbed system, and the local voltage attenuation amount remote from control system is big, and maintenance is not
Convenient problem,
Dcs is used after transformation, F1F2, F3F4 respectively use an IO control cabinet on the spot, and this control method has
Unwrapping wire facilitates the function of signal acquisition apart from short.
Transformation to tension control system；Since former controller is using S7-412 control system, this control system
Operational capability is insufficient so tension force has transmission device operation, and there is tension force narrow ranges for this control mode, need
Want manual intervention amount big, tension unstable defect when threading.
TDC is fed back to using a vertical signal for tensometer acquisition after transformation, the speed of four racks of control is calculated by TDC
Degree, perfectly solves that tension range is narrow, and manual intervention amount is big, tension unstable problem when threading.
Transformation to finish rolling spray beam, for former frame spray beam using manual segmentation control methods, segmentation precision is low (intermediate
900mm long sprays, then mono- section of both sides 200mm), the size of each nozzle injection is uncontrollable.
High using the control mode segmentation precision of electric control pulse after transformation, the amount of each nozzle injection is controllable, cooperation
The problem of roller very good solution plate face, version type.
Temperature scaling factor is increased simultaneously, the control precision of speed ring and thickness ring is improved, simplifies operator
Operation.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, still falls within
In the range of technical solution of the present invention.
