Abstract
The invention relates to a motion controller based on an EtherCAT bus. The controller comprises a keyboard, a mouse, an integrated industrial PC with a display and the motion controller based on the EtherCAT bus. The motion controller based on the EtherCAT bus is connected with the integrated industrial PC with the display. The motion controller based on the EtherCAT bus is connected with a driver based on the EtherCAT or the driver. The controller of the invention has the following advantages that: a structure is simplified; cable cost is saved; simultaneously various kinds of cheap general drivers can be fully used; a scheme is completely complied with the EtherCAT; the controller and the EtherCAT driver can be used in a mixed way by a user.
Description
Technical field
The present invention relates to a kind of motion controller, relate in particular to the circuit module of this motion controller.
Background technology
Motion controller is the brain of numerically-controlled machine, and its Control Driver drives motor and accomplishes accurate complicated motion instruction.
Motion controller has two big types, embedded system and based on the system of PC.Embedded system is because volume is little, and cost is low, has captured most low-end market.But because the embedded system arithmetic capability, memory capacity is limited, and upgrading and expansion difficulty are dominated so high-end market also is based on the system of PC.
Visible by Fig. 1: traditional motion controller adopts ISA or pci interface to be connected on the Industrial PC usually.PC carries out exchanges data through pci interface and motion controller, and motion controller links through various cables and driver again.
The problem of this mode is that number of cables is many, serious interference.Usually driver is installed in the regulator cubicle at lathe rear portion.If Industrial PC also is placed in the regulator cubicle, arrive the display of lathe front so, the cable of input-output device is just very long, is easy to produce disturb.For example the USB extended line can not surpass 2 meters, otherwise must add repeater; The VGA line also must add shielding protection otherwise be easy to occur phenomenons such as ripples line.If be arranged in the lathe front to Industrial PC, the data line and the feedback line that arrive driver so can be very long, and these cables cost an arm and a leg.
Visible by Fig. 2: as, to have occurred a lot of industrial bus standards now based on Ethernet in order to solve the drawback of such scheme.Mitsubishi, Panasonic have all released the industrial ethernet protocol standard of oneself, and the part producer in Europe has also released the standard of open protocol.Their ultimate principle all is the same.
It is too much that the serial network scheme has well solved cable, disturbs greatly expensive problem.But industry control giants have released the solution of oneself, and these schemes are incompatible, and self energy is selected the product of a family, and the user does not have the right of independent assortment.
The EtherCAT agreement in Europe is the industrial real-time Ethernet agreement of an opening; Popular gradually in Europe at present; Be current tool practicability meaning and the open real-time industrial ethernet high-speed serial bus technology that is applicable to motion control; The sync interval of EtherCAT can reach the following magnitude of hundred us, and the synchronization jitter of declaring can be low to moderate 20ns, and its application layer also can adopt the ready-made agreement of CANopen or SERCOS.Main website can adopt common network interface card to cooperate real time operating system to accomplish.But price wants high a lot of with respect to Japanese product, promotes at home and is still waiting time.
No matter employing sealing product under the contract still is that the open protocol product problem that must face is: existing a large amount of inexpensive drives can not use, and the choice diminishes.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of motion controller based on the EtherCAT bus, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The present invention includes: keyboard and mouse; Also comprise: have the integrated industrial PC of display and based on the motion controller of EtherCAT (open industrial real-time Ethernet agreement) bus; Described motion controller based on EtherCAT (open industrial real-time Ethernet agreement) bus links to each other with the integrated industrial PC that has display through netting twine; Describedly link to each other with driver or driver based on EtherCAT (the industrial real-time Ethernet agreement of opening) based on the motion controller of EtherCAT (open industrial real-time Ethernet agreement) bus.
Compared with prior art; The invention has the beneficial effects as follows: not only simplify the structure, save the cable expense, can make full use of the universal driver of various cheapnesss simultaneously; And this scheme observes the EtherCAT agreement fully, and the user can mix with the EtherCAT driver and uses.
Description of drawings
Fig. 1 is that PC carries out data exchange module figure through pci interface and motion controller in the prior art.
Fig. 2 is that the industrial bus motion controller based on Ethernet carries out data exchange module figure in the prior art.
Fig. 3 is a module map of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Visible by Fig. 3: as to the present invention includes: keyboard and mouse; Also comprise: have the integrated industrial PC of display and based on the motion controller of EtherCAT (open industrial real-time Ethernet agreement) bus; Described motion controller based on EtherCAT (open industrial real-time Ethernet agreement) bus links to each other with the integrated industrial PC that has display through netting twine; Describedly link to each other with driver or driver based on EtherCAT (the industrial real-time Ethernet agreement of opening) based on the motion controller of EtherCAT (open industrial real-time Ethernet agreement) bus.
The integrated industrial PC that the present invention will have display directly moves on to master console, has saved through cable link to each other with integrated industrial PC (with the difference in the classic method 1); Through the motion controller based on EtherCAT (open industrial real-time Ethernet agreement) bus, this motion controller can link to each other by the EtherCAT driver on the one hand again, can also link to each other with the traditional driving device through ISA or pci interface on the other hand.
The present invention not only simplifies the structure, and saves the cable expense, can make full use of the universal driver of various cheapnesss simultaneously, and this scheme observes the EtherCAT agreement fully, and the user can mix with the EtherCAT driver and uses.
