The motor motion control card comprises a PCB where a PCI interface, a programming control circuit module, a general I/O port, a double-port RAM chip and a DSP controller are arrange. A programming control circuit is built in the programming control circuit module, and the computer is connected to the programming control circuit through the PCI interface on the PCB. The general I/O port is connected with the programming control circuit module, and two connection ports are arranged on the double-port RAM chip which is respectively connected to the programming control circuit module and the DSP controller through the connection ports. The motor is connected on the PCB. The motor motion control card is simple in structure and convenient for maintenance.
Description
Technical field
The utility model relates to a kind of motor movement control card.
Background technology
Traditional step motor control mode mostly is: upper computer expert draws the position of corresponding axis and is converted to corresponding umber of pulse by setting formula transmission arteries and veins to step actuator after crossing calculating, this control mode can take a large amount of computer CPU computational resources, also can influence the operation of machine when computer is opened a plurality of program.This control mode also can produce clock frequency and change because of the difference of computer configuration, reconfigure problems such as the interior acceleration of upper computer software, speed, does not accomplish that upper computer software is unified.
The utility model content
The purpose of this utility model is that at above-mentioned defective the instruction and the data that provide a kind of host computer in the course of the work only need provide seldom just can allow associated motor move and host computer hardware is not had the control card of very high requirement on request.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of motor movement control card, it connects the motor of computing machine and numerically-controlled machine, the instruction of the control motor that object computer sends is also given computing machine with the condition feedback of motor, described motor movement control card comprises a pcb board, described pcb board is provided with a master control circuit pci interface, a programming Control circuit module, one general purpose I/O port, a dual port RAM chip, a dsp controller, the built-in programming Control circuit of described programming Control circuit module; Described computing machine is connected with described programming Control circuit by the master control circuit pci interface on the described pcb board, described general purpose I/O port is connected with described programming Control circuit, described dual port RAM chip is provided with two connectivity ports, be connected with described programming Control circuit, described dsp controller respectively by this connectivity port, described motor is connected on the described pcb board.
Described programming Control circuit is the large scale programming control circuit.
It is carried on described programming Control circuit on the chip, be used for interface bridge as described master control circuit pci interface and realize that described dsp controller docks with described computing machine and communicate by letter that the I/O signal with described computer software generation exports described general purpose I/O port to simultaneously.
Described dsp controller built-in chip.
Described general purpose I/O port adopts full photoelectric device.
In use, described computing machine is connected with described pcb board by described master control circuit pci interface, and output order, the data of this instruction enter described dual port RAM chip after decoding by described programming Control circuit module, described dsp controller obtains after the data and data is carried out respective handling from described dual port RAM chip, deposit data in described dual port RAM chip after finishing processing, described computing machine reads data from described dual port RAM chip after receiving information.Wherein, it is as the pci interface bridge that the built-in programming Control circuit of described programming Control circuit module mainly acts on, the chip data of the related data that described computer software is produced in described pci interface and described dsp controller as interface butt joint communicate by letter, realize simultaneously the I/O signal of described computing machine machine software generation is sent to general purpose I/O port.
Described programming Control circuit module is different with described dsp controller chip operation clock frequency can't realize direct data communication, at this moment, the dual port RAM chip serves as the data cache chip and realizes data communication between described programming Control circuit module and the described dsp controller.
Dsp controller control is to the position motion control of stepper motor or servomotor, and when controlling two motor movements at the same time, diaxon has independently spacing, stop signal.
Advantage of the present utility model is, the host computer instruction and the data that only need provide seldom control card just can allow associated motor move on request in the course of the work, and the real-time control of motor is all finished by the dsp chip on the control card.Behind equipped this control card host computer hardware is not had very high requirement, host computer also can move other program simultaneously in the operation of control machine, and the correlation parameter of machine operation also can unify to make things convenient for the maintenance of equipment.
