China in structure of software of system of I numerical control introduces

Software structure summarizes the systematic software of system of the Ⅰ in · China numerical control to comprise by two parts: Rock-bottom software (software platform) superstratum software (process layer software) the part under the dotted line in · graph: DOS, RTM and NCBIOS RTM module: For the real time of own development much task manages module, the task management of responsible CNC system attempers. NCBIOS module: To input a system basically, administrative CNC system all exterior control objects, include equipment driver (I/O) computation of control of management, position, PLC control, interpolation and in-house monitoring. NCbase: A general designation of RTM and NCBIOS. · superstratum (the process controls a layer) software: Part of dotted line above. Main function module: Setting of editor, parameter, translation program, PLC management, MDI, breakdown shows wait to handle concerned function with the user child module. System of different numerical control, the distinction of its system function and increase and decrease all come true in this one. Each function module undertakes through NCBIOS and ground floor information is exchanged, make the hardware of superstratum module and system has nothing to do. This is the crucial place that this system has open sex. 2.

The functional · of NCbase real time much task attempers this function comes true by RTM module, it is to pass the INT08 of DOS to interrupt what the function constructs to attemper core will come true to attemper to much task. Attemper core structure reachs his much task attempers of task of graph · CNC differentiate those who reach first step is affirmatory China in I differentiate the task it is 8, first step from list high to low platoon for: The position controls the job (4ms) ; Interpolation computation task (8ms) ; Data collects the task (12ms) ; PLC task (16ms) ; Task of knife complementary operation (condition (buffer) drive) ; Coding explains the errand (condition (buffer) drive) ; Dynamic indication task (96ms) ; Man-machine interface (menu management, task of one-time dead loop) . Function of · equipment driver: Contented and different control object (machining center, milling machine, lathe, grinder) the requirement that different hardware configures pair of different driver. Realize systematic versatility. Come true: When deploying a system, be in the driver of all hardware module the NCBIOS of NCBIOS.

CFG (the CONFIG that is similar to DOS.

SYS file) in explain. When the system is moving, NCBIOS basis NCBIOS.

Of CFG beforehand setting, transfer into the driver of corresponding module, establish corresponding interface channel. Attemper a control of position of control of position of · of nucleus block diagram is NCBIOS fixed program, its are main the function is the positional control statement that accepts interpolation operation program to deliver, after waiting for processing via undertaking differentiate of position of pitch error compensation, transmission clearance compensation, maximum, output speed dictates the value controls module to the position. · interpolation implement China in I amount to charges systematic much passage (can amount to 4 passageways at most) numerical control system, every passageway has an interpolation implement, establish an interpolation mission accordingly. This task basically completes the following work: Linear, circular arc, whorl, tap and small straight line segment (for freedom curve and treatment of free curved surface are used) the interpolation operation that wait. · PLC attempers the main task that PLC attempers is: Breakdown calls the police to stop processing, MST processing, urgently to manage with life of processing of drive of restoration processing, fictitious axis, cutting tool, indicator light and processing of switch of operation face plate, sudden incident processing. 3.

The function of interface · NC that NCBIOS provides superstratum software calls interface interpolation implement interface: For interpolation pretreatment (coding, knife fills, speed pretreatment) data gives rock-bottom software; Breakdown information exchanges interface; Equipment calls interface. Software of superstratum of area of · data news report observes systematic condition through data division, include reference axis state (buy of position of axle, follow speed of error, motion) , input / output condition, PLC interior condition.
