Description

Glove machine control system based on embedded processors ARM and DSP

Technical field

The present invention relates to a kind of control system, specifically a kind of glove machine control system based on embedded processors ARM and DSP.

Background technology

Glove knitting machine is a kind of Knitting Machinery, is used to weave safety and industrial gloves, various fashionable dress gloves, demi glove, full finger gloves, Cold-proof gloves and fashion gloves etc., the huge market demand.Traditional glove machine control system generally adopts the development plan of multiple single chip microcomputer, each control module is generally all independent works separately, and integrated level is not high, and reliability is low, each control module influences on system architecture and jamproof performance so to some extent by the RS232 communication.

Summary of the invention

A kind of glove machine control system based on embedded processors ARM and DSP of providing at the deficiencies in the prior art is provided, this system adopts embedded processors ARM (senior reduced instruction level) processor and DSP (digital signal) processor to realize its each function as controller, satisfies the weaving requirement.

The object of the present invention is achieved like this:

A kind of glove machine control system based on embedded processors ARM and DSP, this system comprises:

Be core with the arm processor and be provided with man-machine interface and the host computer of flower type input interface;

Be core with the dsp processor and carry out the order that host computer sends here and will order the slave computer that sends to corresponding execution module accordingly;

The communications protocol that connects host computer and slave computer.

Described corresponding execution module is control head servo control mechanism, sandspit selection mechanism, needle selection device and head cam mechanism.

Described communications protocol adopts the Modbus agreement, and each subsystem in the control system is carried out exchanges data.

The present invention can improve message transmission rate, enlarges flower type file storage, increases the dirigibility of design and use, improves the production efficiency of glove knitting machine greatly.

Embodiment

Below in conjunction with accompanying drawing, the present invention is specifically described.

Consult Fig. 1, host computer of the present invention is responsible for man-machine interface, the input of flower type file and the evaluation work of parsing, and slave computer mainly is responsible for receiving the control data and the control output of host computer, and the information that receives collection in worksite is simultaneously given host computer.

Host computer of the present invention is core with the arm processor, realizes the processing of man-machine interface and pattern data.This host computer reads in the colored type file that is generated by computing machine flower type preparation system by flower type input interface earlier, adopt high order power analytical algorithm that file is carried out the conversion of data layout, and capable control data in the file and pin control data are passed to the real time execution that the slave computer dsp processor is controlled glove knitting machine.Host computer also receives and handles a large amount of real time data and sensor signals from slave computer simultaneously, adopts integration summation algorithm with the compression of glove knitting machine real-time working status data, simultaneously some important parameters wherein is presented on the interface.

Slave computer of the present invention adopts dsp processor, explains and carry out the order that host computer is sent here, is about to control commands corresponding and sends to corresponding execution module.As control head servo control mechanism, sandspit selection mechanism, needle selection device and head cam mechanism etc.

Consult Fig. 2, after powering on, the present invention carries out initial work, inquire about up to initialization then and finish, the wait button is pressed after entering main interface, if the button indication enters running status, whether have key press, whether detect flower type input interface in addition on the one hand has Data Receiving to arrive if continuing on the one hand to detect in the program; If what the button indication entered is that parameter is provided with state, program is provided with process with the calling function parameter so.Functional parameter is provided with in the process, adopts high order power analytical algorithm will spend the parameter of revising in data that the type input interface receives and the parameter setting up procedure to carry out compound parsing; High order power analytical algorithm adopts following formula:

Y＝A _nX ⁿ+A _n-1X ^n-1+A _n-2X ^n-2+……A ₁X+A ₀

In the formula: Y is for resolving flower type command result, the data that glove knitting machine control involved in the present invention is used;

An, A _N-1A ₁, A ₀For resolving coefficient, value is a natural number;

X is the parameter of revising in data that flower type input interface is received and parameter setting up procedure.

Be in normal operating condition during the glove knitting machine operate as normal, in the real-time judge process whether stop key is pressed always.Embedded ARM processor receives the glove knitting machine status data that the digital signal dsp processor is uploaded in real time in the normal operating condition process, and adopts integration summation algorithm with data compression, and concrete formula is as follows:

$P_k=\underset{j=1}{\overset{50}{\mathrm{\Σ}}}{Q}_{\mathrm{kj}}\left(t\right)$

In the formula: P _kBe the data result that compresses in the embedded ARM processor;

Q _KjFor at current time 50 groups of glove knitting machine status datas that the digital signal dsp processor is uploaded forward;

Because software adopts 20mS regularly to interrupt among the present invention, so the numerical value of j is chosen from 1-50 the current time glove knitting machine machine state data of 1S forward just.

If have order out of service to occur in the course of the work then system quits work.

Claims (3)

1, a kind of glove machine control system based on embedded processors ARM and DSP is characterized in that this system comprises:
