Accompanying drawing explanation
Fig. 1 is the flow chart of steps that realizes the method for machining control in digital control system by the Machine-Tool Control order of reading system outside of the present invention.
Embodiment
In order more clearly to understand technology contents of the present invention, especially exemplified by following examples, describe in detail.
Referring to shown in Fig. 1, is the flow chart of steps that realizes the method for machining control in digital control system by the Machine-Tool Control order of reading system outside of the present invention.
In one embodiment, the method that should be in digital control system realizes machining control by the Machine-Tool Control order of reading system outside comprises the following steps:
(1) according to user's operation, described digital control system is an outside Machine-Tool Control command set file by the Machine-Tool Control demanded storage of this system outside;
(2) described digital control system starts, initialization system kernel, and operational system master routine, and described system master routine operation has resolver;
(3) according to user's operation, described digital control system receives processing instruction, and this processing instruction can be main shaft enabled instruction, returning to mechanical reference point instruction or mobile main shaft instruction etc.;
(4) described digital control system master routine is sent to described resolver by described processing instruction by Message routing mechanism;
(5) the processing application of instruction described in described resolver judgement is the outside Machine-Tool Control order of the order of internal system Machine-Tool Control or system, if internal system Machine-Tool Control order, enter step (6), if the outside Machine-Tool Control order of system, enters step (7);
(6) machining control is carried out in the inner Machine-Tool Control order of the direct calling system of described digital control system;
(7) described resolver calls corresponding Machine-Tool Control order in described outside Machine-Tool Control command set file according to described processing instruction by Message routing mechanism;
(8) the Machine-Tool Control order of the system outside described in described resolver resolves, and the steering order obtaining after resolving is sent to digital control system;
(9) digital control system described in is carried out the control command obtaining and is carried out machining control.
In one, more preferably in embodiment, described outside Machine-Tool Control command set file is the outside Machine-Tool Control command history file that comprises multiple subprogram segments, and described each subprogram segment all has subroutine opening flag and end of subroutine sign.
In a kind of further preferred embodiment, described step (4) specifically comprises the following steps:
(41) digital control system is sent to described resolver by described processing instruction by Message routing mechanism;
(42) the described resolver function corresponding with it according to described processing instruction calls;
(43) described resolver obtains the subroutine name in function.
In the preferred embodiment of one, what the resolver described in step (5) judged described processing application of instruction is the order of internal system Machine-Tool Control or the order of internal system Machine-Tool Control, be specially: resolver judges in the inner Machine-Tool Control order of digital control system whether have the steering order corresponding with described subroutine name, if have, it is the order of internal system Machine-Tool Control, if nothing is the outside Machine-Tool Control order of system.
In the preferred embodiment of another kind, resolver described in step (7) calls corresponding Machine-Tool Control order in described outside Machine-Tool Control command set file according to described processing instruction by Message routing mechanism, is specially: described resolver calls the corresponding subprogram segment of the subroutine name with described in described outside Machine-Tool Control command set file by Message routing mechanism.
In actual applications, by the auxiliary control program of corresponding machine tool motion operation, unified being put in Public.dat (subroutine) file, when carrying out lathe action, calls corresponding subroutine by master routine, completes relevant action.Actual application comprises the following steps:
1, program startup is written into Public.dat (subroutine) file;
2, system starts, and kernel initialization is waited for and being accepted from the relevant subprogram segment of the message call at interface;
3, for example, when user clicks corresponding machine operation button or the specific work flow of some clients (: the operations such as main shaft startup, returning to mechanical reference point, mobile main shaft), by Message routing mechanism, message is sent to resolver;
5, receive message, by the corresponding subroutine of message call;
5, by resolving, the instruction in subroutine is resolved, complete the control to digital control system.
Particularly, when cnc system software starts, in main thread, " Public.dat " file is written into, wherein " Public.dat " file is all outer bevel collection of programs, user may be because client's difference causes the action unification that control mode is different to be put in subroutine by some, as " returning to mechanical reference point ", " work flow control of client " etc., " Public.dat " every cross-talk program has its subroutine opening flag and end of subroutine sign.Then user operates, as clicked " returning to mechanical reference point " push-botton operation, as processing starts needed work flow control, in process, more needed controls are inserted, action of process finishing etc., all can call its relevant subroutine control according to its message or ad hoc fashion.When client has carried out after associative operation, system can be according to its corresponding function of message call, and in by this function, given subroutine name calls relevant subroutine, controls digital control system and does relevant action.
Adopted the method that realizes machining control in digital control system by the Machine-Tool Control order of reading system outside, its Machine-Tool Control demanded storage by this system outside is an outside Machine-Tool Control command set file; In digital control system, receive after processing instruction, what first by resolver, judge described processing application of instruction is the outside Machine-Tool Control order of the order of internal system Machine-Tool Control or system, if internal system Machine-Tool Control order, directly machining control is carried out in the inner Machine-Tool Control order of calling system, if the outside Machine-Tool Control order of system, resolver calls corresponding Machine-Tool Control order in described outside Machine-Tool Control command set file by Message routing mechanism; And after the Machine-Tool Control order of this system outside of resolver resolves, by digital control system, according to this steering order, carry out machining control, with this, realized the machining control of the Machine-Tool Control order based on system outside.Thereby can remove human and material resources and the time of overlapping development control command in prior art from, and then significantly improved the application efficiency of digital control system, and the method that realizes machining control in digital control system by the Machine-Tool Control order of reading system outside of the present invention, its process is simple and convenient, stable and reliable working performance, the scope of application is also comparatively extensive.
In this instructions, the present invention is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
