Description

The micromonitor system of circular knitter

Technical field

The present invention relates to a kind of micromonitor system of circular knitter, mainly be utilize a processing unit with input block, communication unit, and the function of control module be integrated into a kind of three-in-one micromonitor system.

Background technology

Knitting machine from early stage manual loom to automation, the automation industry has obtained very much progress, " food, clothing, live, OK " is very important, along with constant development of economy, the modern society masses more and more pay attention to clothing, relatively also more and more exquisite to the quality of clothes, for this reason, hosiery trade must quicken to produce step to cater to public demand at present.

Knitting machine is produced the dealer after knitting machine production installs at present, promptly sells textile mills and uses, and the braiding that the user can utilize these knitting machines to carry out various cloth kinds generates.When utilizing knitting machine to carry out the braiding of cloth kind, in case knitting machine breaks down, in the time of can't keeping in repair or adjust, the user need notify the producer immediately, and the producer sends the maintenance personal to go to the user to set up the board place immediately and keeps in repair, and makes knitting machine recover woven condition again.

Existing knitting machine control device utilizes the action of programmable logic controller (PLC-Programming Logic Controller) control knitting machine, but transmission course is often because of the influence or the other factors of external environment, and influence the stability of transmission course, below at the design and the application of the control device of existing knitting machine, division is as follows:

See also shown in Figure 1, in the framework based on programmable logic controller (PLC) 13, the pipeline of linking up with communication module group 12 is based on RS232 line 17, and an end of communication module group 12 joins with RS232 line 17 and contact panel (Touch Panel) 11, the other end also is connected to adapter 14 with RS232 line 17, is based on RS485 line 18 between adapter 14 and the host side 15.Though having external environment, communication do not influence its speed and stability, but it is single with regard to RS232 line 17, wherein must take into account the speed of programmable logic controller 13 and program capacity, because of programmable logic controller 13 program sizes own are directly proportional with the program scanning time relation, the program of also promptly the writing time of more exposing thoroughly heals long, so just existing program program time is necessary for 24ms, but also promptly need just been scanned of these time-program(me)s, this is a very big secret worry to whole system, because of at any time any situation may take place in these times, if when having situation to take place, just sweep time shortly past or do not arrive just can't real time reaction to system, system thereby take place to postpone and produce the damage that to expect, because the interference of environment, the quality of itself, quality of adding programmable logic controller 13 inner bodies etc. all can exert an influence to it, and prior art can only be controlled a circular knitter 16 with a programmable logic controller 13, control many circular knitters 16 simultaneously if want many programmable logic controllers 13, its cost is appreciable, in view of this, the present invention conceives one group of complete micromonitor system, to remedy the problem of prior art.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of bulk velocity and reaction time that can promote circular knitter, and then increases input and export the micromonitor system of counting and reducing cost.

Micromonitor system proposed by the invention, mainly be utilize a processing unit with input block, communication unit, and the function of control module be integrated into a kind of three-in-one micromonitor system to promote bulk velocity, mechanical origin, communication all use the mode of interrupting to handle in micromonitor system, the processing mode of interrupting is a real-time requirement in micromonitor system, its reaction speed almost takes place simultaneously with extraneous signal, so can't postpone on the reaction time.

Fig. 3 is a processing unit flow chart of the present invention.

Fig. 4 is the calcspar of another preferred embodiment of the present invention.

The specific embodiment

About preferred embodiment of the present invention and technology contents, existing accompanying drawings is as follows:

See also Fig. 2, shown in 3, micromonitor system 21 comprises:

One input block 211 is touch-control display panels, provides operating function on this panel;

One processing unit 212, it is a microcontroller, receive the input signal of this input block 211, utilize its signal and then directly control other unit, this processing unit 212 has input 216, output 217, reaches communication 218 3 big functions, planning and control through high-order C language, can make addressing and data to external world reads and then reaches required every function, at any time can do input via this processing unit 212 and to read, so when the abnormal signal of system occurred in input, processing unit 212 just can react at any time to system and not have delay;

One communication unit 213, receive the input signal of this processing unit 212, and be sent to an end of adapter 22 by RS232 line 25, the other end is delivered to host side 23 with RS485 line 26 with this signal, send command instruction by this communication unit 213 by this host side 23 again, treated unit 212 transmits; And

One control module 214, it is a programmable logic controller, the requirement of the command instruction that transmits according to this processing unit 212, the operation sequence of the internal preset of startup own removes to control output device 24 (as knitting machine) by RS485 line 26, makes this micromonitor system 21 promote output device 24 bulk velocities and reaction time like this.

Above-mentioned processing unit 212 utilize addressable winding displacement 215 (as data line) respectively with this input block 211, this communication unit 213, and control module 214 be connected, mainly utilize processing unit 212 that the function of input block 211, communication unit 213 and control module 214 is integrated into a kind of three-in-one micromonitor system 21, in order to increase confidence level, in micromonitor system 21, increase by 8 counters and do hardware interrupts; Mechanical origin and communication all use the mode of interrupting to process in micromonitor system 21.The processing mode of interrupting is a real-time requirement in processing unit 212, that is to say when there is requiring of interruption the outside, processing unit 212 must remove to handle external demand at once, its reaction speed almost is to take place simultaneously with extraneous signal, so when as long as extraneous signal such as mechanical origin or communication need enter processing unit 212, this processing unit 212 just with the required requirement of velocity process of several nanoseconds (ns), does not take place so do not have delay in the reaction time.

See also shown in Figure 4, it is another preferred embodiment of the present invention, use micromonitor system 21 operation circular knitters 27 (its control flow is as aforementioned) of the present invention, because micromonitor system 21 transmission speeds are than existing fast many, so micromonitor system 21 can also be by an online control number circular knitter 27, improve output, in today of stressing advantage competition power, product must meet low cost, efficient height, reach compact requirement, micromonitor system 21 not only can reduce cost, also can increase free space.

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
