Description

A kind of multifunctional movement programmable control system based on Digital Signal Processing

Technical field

The present invention relates to a kind of utilization of Digital Signal Processing in terms of motion control, more particularly to one kind is based on number The multifunctional movement programmable control system of word signal transacting.

Background technology

At present, it is multi-shaft interlocked to wait industrial design gradually to popularize in Industry Control, it is so-called multi-shaft interlocked to refer in a machine It is processed simultaneously in multiple reference axis (including rectilinear coordinates and rotational coordinates) on bed, and can be in Computerized digital control system (CNC) coordinated movement of various economic factors simultaneously is carried out under control.Multi-axis simultaneous machining can improve the machining accuracy of Space Free-Form Surface, quality And efficiency.The positive high speed of modern digital control processing, high precision int, high-intelligentization, high flexibility, high automation and high reliability side To development, and multi axes Digit Control Machine Tool just embodies this point.

With continuing to develop and perfect for process technology, wherein containing, writing for program is increasingly simple, and this is in very great Cheng Amount of calculation of the engineers in program is alleviated on degree, while the workload for the person that also mitigates machine operation and improving production Efficiency, has won cost, and Multi-axis simultaneous machining is the developing direction of modern machine, embodies the height of a national manufacturing industry level It is low.

But the fortune of multi-shaft interlocked and action control (such as cylinder, hydraulic cylinder) is realized in many numerical control systems at present Dynamic control is realized by motion control card plus PLC, and the architecture design of this kind of system causes hardware cost high and control model Underaction.

The content of the invention

In order to solve the above problems Digital Signal Processing is flexibly based on so as to design a kind of with low cost but control mode Kinetic control system and control method.

The technical solution adopted for the present invention to solve the technical problems is：A kind of multi-functional fortune based on Digital Signal Processing Dynamic programmable control system, including the output of digital signal processor module, input module, communication module, output module, relay Module, I O Interface module, AD conversion module, input capture module, interruption control module, coder module and INT input mould Block, the input module is used to receive input signal and be connected with digital signal processor module, the digital signal processor Module also respectively with for realize control signal output output module and relay output module be connected, at the data signal Manage device module also with the communication module interconnection for external receiving and transmitting signal, the I O Interface module, AD conversion module, input catch Catch module, interruption control module, coder module and INT input modules to electrically connect with digital signal processor module successively, institute Input module is stated to pass including PLD FPGA module, SDRAM memory modules, SRAM memory modules and high-speed a/d C Defeated interface, the SDRAM memory modules, SRAM memory modules and high-speed a/d C coffrets respectively with PLD FPGA module is connected, and the PLD FPGA module is connected with digital signal processor module.

Preferably, the input module also includes Fast Ethernet controller and Ethernet interface, the Ethernet connects Mouth is connected by Fast Ethernet controller with PLD FPGA module.

Preferably, the input module also includes expansion interface, the expansion interface and PLD FPGA Module is connected.

The beneficial effects of the invention are as follows:The present invention design not only can be in specific industrial applicability environment (data Amount, kind of interface, the species of action control) corresponding control realization is carried out, and can be to ordering automatic carry out automation knowledge Not with automation action control, and the implementation pattern of PLC and motion control card can be no longer rely on, so as to greatly reduce hard Part cost, further improves degree of flexibility and the sensitivity of control model；In combination with PLD FPGA moulds Block, which can be realized further, can reach to motion control the parameter designing talked about automatically and control are realized by programming.
