Fig. 4 is refer to, is the laser cutting machine method flow diagram that double-type control is realized in an embodiment.
This realize double-type control laser cutting machine method be based on include PC, man-machine converter, movable type it is man-machine and Fixed man-machine digital control system, the man-machine converter be used for will the fixed man-machine, movable type it is man-machine with the PC Connection, comprises the following steps:
Step S110:It is portable man-machine or fixed man-machine to the man-machine converter transmission operation signal.
In the present embodiment, portable man-machine and fixed man-machine dual operation side can be realized by man-machine converter Formula, i.e. user can be operated by portable man-machine or fixed man-machine any one mode.But synchronization, man-machine conversion Device can only receive the operation of one of both, i.e., portable man-machine and fixed man-machine can not be operated simultaneously.
Step S120:The man-machine converter sets the communication symbol of guidance panel data according to the operation signal.
The communication symbol includes the communication symbol and fixed human-machine operation panel of portable human-machine operation panel data The communication symbol of data.Such as, user is want by the fixed man-machine control for carrying out guidance panel, then when user selects to fix After formula human-machine operation, it is fixed it is man-machine will to man-machine converter send an operation signal, at this moment man-machine converter will root The communication symbol of fixed human-machine operation panel data is set according to its operation signal for receiving.
In the present embodiment, the communication symbol of portable human-machine operation panel data is " 0 ", fixed human-machine operation panel The communication symbol of data is " 1 ".It is appreciated that in other embodiments, can using other modes set two kinds it is different logical News mark, is not restricted here.
Step S130:The man-machine converter carries out data communication treatment according to corresponding communication symbol.
Incorporated by reference to Fig. 5, in the present embodiment, the man-machine converter includes first serial and second serial, step S130 Specifically include following steps:
Step S132:Application Interruption server, first serial ISR and second serial ISR Resource is simultaneously initialized.
In the present embodiment, the first serial is used for the data communication for realizing between the PC and man-machine converter, The second serial be used to realizing the man-machine converter and it is portable man-machine or it is fixed it is man-machine between data communication.
Step S134:The Interruption server controls the first serial ISR and the every Preset Time Two serial ports ISRs send and once interrupt data.
In the present embodiment, the Preset Time is 25 milliseconds.It is appreciated that in other embodiments, can arbitrarily set The Preset Time is put, is not construed as limiting here.
Step S136:The first serial and the second serial are carried out at data communication according to corresponding communication symbol Reason.
In the present embodiment, to carry out the step of data communication is processed according to corresponding communication symbol specific for the first serial For:Detect whether the Interruption server controls first serial ISR to have sent interruption data, if so, described The communication data received from the PC is sent to the second serial by one serial ports, if it is not, the first serial receives institute State the communication data of PC transmission.Wherein, the communication data represented when communication symbol is " 0 " PC with it is portable it is man-machine it Between communication data, the communication data communication symbol be " 1 " when represent PC and it is fixed it is man-machine between communication data.
In the present embodiment, to carry out the step of data communication is processed according to corresponding communication symbol specific for the second serial For:Detect whether the Interruption server controls second serial ISR to have sent interruption data, if so, described The data is activation that two serial ports will be received from first serial gives described fixed man-machine, if it is not, the second serial receives movement Formula is man-machine or data of fixed man-machine transmission.
Specifically, if communication symbol is " 0 ", second serial receives the data of portable man-machine transmission, and scanning updates and moves Dynamic formula human-machine operation panel data are without processing fixed human-machine operation panel data;If communication symbol is " 1 ", second serial The data of fixed man-machine transmission are received, that is, processes fixed human-machine operation panel data without to portable human-machine operation panel Data are scanned renewal.
Further, in the present embodiment, the step of also including that carrying out interrupt spot protects before step S134, step The step of also recovering including interrupt spot after S136.
The above-mentioned laser cutting machine system and method for realizing double-type control, there is provided man-machine converter and portable people Machine, the man-machine converter be used for will it is described it is fixed it is man-machine, movable type it is man-machine be connected with the PC, to realize the fixation Formula is man-machine and mobile man-machine while have the function of display, operational control, data input, so can be with Real Time Observation in debugging Laser cutting process, reaches Real Time Observation and Study of Laser cutting effect.
Embodiment described above only expresses several embodiments of the invention, and its description is more specific and detailed, but simultaneously Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
