Specific embodiment
Such as Fig. 1, in many servo-drive system electrical controls, be connected in center control SU320-CPU for rectification unit and inversion unit by itself distinctive high-speed communication protocol DRIVE-CLIQ by 5120 frequency changing driving systems, middle control CPU can control DC bus-bar voltage, and the electric energy produced in generator mode can be fed back to the utilization of the inversion module of other electric motor modes of supply dc bus on power network, so as to significantly save the electric energy of total system, the towering rotating speed that can control institute's output motor of inversion list and torque.Exchanged while controlling CPU in 5120 and can carry out high speed exogenous data with 57-300PLC by Profibus networks, carry out the control of closed-loop.
5120 frequency conversion systems, have periphery other control system than large effect in high-power test, the especially effect of its higher hamonic wave for producing, therefore configurable test and simulation analysis must be carried out to it before actual behaviour is carried out, selection cable, wave filter and reactor, so that system normal table reliably runs.Can conveniently realize carrying out 5120 systems configuration and simulation analysis whole system using Siemens SIZER softwares.
Such as Fig. 2, S7-300 is programmable controller (PLC) series of products of Siemens production, there is modular construction because of it, distributed configuration is easily achieved and cost performance is high, Electro Magnetic Compatibility strong, concussion resistibility performance is good, make it in extensive industrial control field, as solution that is a kind of not only economic but also gearing to actual circumstances.Because its own there are powerful FB41 continuous analog Control PID control function blocks, can be used to realize that controller is used as into cascade, mixing goods ratio controller as PID fixation set value calculation devices or in multiloop control.It can switch between manual mode and automatic mode.In a manual mode, adjustable variables are corrected to the numerical value for manually selecting.LMN-LMN_P-DISV is configured to inside integrator (INT), and differentiation element (DIF) is configured to 0, these are all internally matched automatically.So, being switched to automatic mode would not cause the suddenly change of regulated value.
Such as Fig. 3, using the modularized design based on state machine, it is mainly made up of whole software systems DATA REASONING, data mart modeling, data storage, 5 parts of state modulator and parameter management.The parameter measurement relevant with control such as lubricating oil temperature in measurement the part mainly rotating speed of completion motor, input torque, the mechanical efficiency of lathe, speed changer.Processing is the essential function of TT＆C system, it can combine each is the to the eye mutually incoherent, parameter system that is independently measured, become to have an impact each other, related Data-Link, so as to form a relatively complete organic data system, overall assessment is carried out to systematic function.Storage is will to be shown and changed in experimental data access to hard disc of computer and accordingly.Control is mainly realized the pid parameter regulation of the rotating speed and torque and temperature control instrument of motor and is set.Management is the foundation for realizing user right and database, is easy to inquiry and classification of historical data etc. in the future.
In whole software systems, it is exactly writing for host computer LabVIEW and slave computer 57-300PLC and rich ten PXR9 signal procedures that its is most important, and it is directly connected to host computer and whether lower computer system can carry out data exchange, can the signal of slave computer upload and can the instruction of host computer be issued in slave computer.For 57-300PLC and PXR-9 temperature control communication instruments, all communicated with host computer LabVIEW using the communication mode of MODBUSRTU, most important of which is exactly hexadecimal translator.
