Description

Man machine alternating system of full digitalization hidder arc wolding
Technical field
What the present invention relates to is a kind of control system of welding technology field, especially a kind of man machine alternating system of full digitalization hidder arc wolding.
Background technology
Submerged-arc welding is to utilize electric arc as one of welding method of the energy, and full name is Lincoln weld, claims automatic arc welding under the welding flux layer again.Lincoln weld has that welding current is big, fusion penetration is big, the welding scope is wide, and production efficiency height, excellent, the automaticity advantages of higher of weldquality have obtained wideling popularize and using in manufacturing sectors such as shipbuilding, bridge, heavy-duty machinery, ocean structures.Automatic submerged-arc welding machine mainly is made up of main power source, control cabinet, dolly three parts.Man-machine interactive system is as one of part of submerged-arc welding.At present, Chang Yong submerged-arc welding man-machine interface is mainly the regulative mode that simple analog quantity on the dolly preset and utilized analog switch; The method of observing for welding process then mostly is pointer current/voltage table.The virtual value that the current/voltage table of pointer-type shows does not observe the information of dynamic change, and requires the time that shows a quite stable of logarithm value, is difficult to carry out the real-time demonstration of dynamic parameter.
Through the prior art literature search is found, " electric welding machine " 2002, Vol.32, No.2, " the intelligent man-machine interface design of multifunctional inversion type arc-welding machine " literary composition of publication on P4~6, this article describes welding methods such as current collection arc thrust Self Adaptive Control MMA welding, TIG weldering, MIG weldering in detail on the intelligent multi-function inverter type welder control system basis of one, adopt input-output apparatus directly perceived such as keyboard input and liquid crystal display, realized that welding method is selected and the intelligent man-machine interaction interface of welding condition setting and modification.Access use but each parameter of regulating is can not be when using next time directly disposable; Behind input parameter, do not recommend the optimal parameter function; Can not any adjusting and control be arranged to action in the welding process by this man-machine interface operation; Single-chip microcomputer is both as welding the major loop core simultaneously as the man-machine interface core in whole system for single-chip microcomputer, and outstanding modularized design on man-machine interface makes man-machine interface upgrading and digitlization be subjected to certain limitation.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art and defective, a kind of totally digitilized submerged arc welding machine man-machine interactive system is provided, make its with double digital signal processor as " from " respectively welding tractor and wire feed system are carried out on the basis of control system, adopting single-chip microcomputer is the man-machine interactive system conduct " master " of core, controls the carrying out of whole welding process by the formulation of multi-computer communication agreement.
The present invention is achieved by the following technical solutions, the present invention includes: processor of single chip computer, digital signal processor be core wire feed module, power module, membrane keyboard module, digital encoder, ferroelectric outer extension memory that digital signal processor is core, be with graph lcd module backlight, order wire.Digital encoder is connected to processor of single chip computer, processor of single chip computer is that wire feed module and the digital signal processor of core is that the power module of core is connected by order wire and digital signal processor, and the other end of processor of single chip computer is connected with being with graph lcd module backlight, ferroelectric outer extension memory, membrane keyboard module respectively.Processor of single chip computer and digital encoder, membrane keyboard module, ferroelectric outer extension memory are connected to form the operational module of man-machine interactive system.
