Description of drawings
Fig. 1 is the schematic diagram of system of the present invention.
The specific embodiment
As shown in the figure, this aluminum foil thickness automatic control system includes the driving control system 1 that is used for transmission control, is used for the auxiliary control Programmable Logic Controller 2 of driving control system exchange of control information and is used to control the THICKNESS CONTROL Programmable Logic Controller 3 of aluminum foil rolling thickness; Described driving control system 1 includes by the interconnective uncoiler DC Transmission of Profibus-DP bus controller, main motor DC drive controller and coiling machine DC Transmission controller.Driving control system 1 also is connected by the Profibus-DP bus with auxiliary control between the Programmable Logic Controller 2, and auxiliary control Programmable Logic Controller 2 is connected with THICKNESS CONTROL Programmable Logic Controller 3 through a field bus communication module 4 and Profibus-S7 bus; The analog quantity importation of described THICKNESS CONTROL Programmable Logic Controller 3 is connected to pressure sensor 5, pressure sensor 5 is connected on the hydraulic cylinder 6 of carrying out THICKNESS CONTROL, and the analog quantity output of THICKNESS CONTROL Programmable Logic Controller 3 is through servo-actuating device 7 control hydraulic cylinders 6.
Among the embodiment, auxiliary control Programmable Logic Controller is a S7-300 Programmable Logic Controller, and the THICKNESS CONTROL Programmable Logic Controller is a S7-400 Programmable Logic Controller, and the field bus communication module is a CP343-5 communication interface module.
The concrete course of work branch of the real system of the present invention comprises supporting process control, transmission process control, and thickness is controlled three parts automatically and is formed.
Auxiliary control procedure is finished by auxiliary control Programmable Logic Controller.Concrete work comprises the startup of control hydraulic power unit/stop, the startup of lubricated pumping plant/stop, and each mechanical-hydraulic moves.In addition, a most important job is that it has born the communication (send and receive) that divides with transmission control part, thus for example auxiliary control section sends combined floodgate, separating brake, wears band, operation, tension force input/remove, stop, stop fast, anxious signal such as stop controls running part switching value signal control driving motor.Running part also can feed back to the motor practical operation situation auxiliary control section simultaneously, for example: operation informations such as motor temperature, motor speed, current of electric, electric moter voltage, motor torque, tension force, actual coil diameter.
The thickness automatic control process can select to adopt three kinds of working methods: pressure control, pressure and tension force control, pressure and speed control.
Pressure controling mode is exactly to carry out pressure information directly by analog quantity importation input thickness control Programmable Logic Controller by a pressure sensor collection that is contained on the THICKNESS CONTROL executing agency hydraulic cylinder, system can compare setting pressure and actual pressure, if being arranged, deviation sends regulated quantity changes executing agency to servo-actuating device stroke by analog output module with regard to the automatic pressure regulation signal, also can stir operating grip by operator and be input to digital quantity input module and manually adjust pressure, the digital quantity output module also can be told operator by indicator lamp with the order that now moves simultaneously.
When if desired tension force and speed being put into thickness control system, the THICKNESS CONTROL Programmable Logic Controller will partly be accepted the information of being correlated with from assisting the control Programmable Logic Controller by the field bus communication module, as: motor speed, motor torque, current of electric, by calculating regulated quantity of output, send to the controller of driving motor again by the field bus communication module, regulate the speed and the torque of motor, thus guarantee rolling product thickness even.
