Description
(1) technical field
The utility model relates to a kind of flat machine computerized control system.
(2) background technology
Flat machine is one of main production equipments of knitted textile products, is fit to cotton, hair, fiber crops, silk, cashmere, reaches the braiding of various chemical fibres, scribbled.Since the 1980s, the theory of being followed the fashion and advocating individual character influences, the functionalization of knitted textile products, variation and individual character have changed into the main trend of production development, developed countries such as Japan, Germany, Italy develop according to market demand and have realized electronization, digitized flat machine of new generation---computermatic straight-bar machines, and this equipment has become flat machine developing direction from now on.China is weaving big country, and textile industry is again the mainstay industry of this province, and textile economy occupies critical role in our province national economy.The modern textile science and technology development with global economic integration fusion day by day, is developing the our province textile industry rapidly and is technology-intensive industries.But occupy national production reach 1/4 the knitted textile products production equipment---straight-bar machines still is controlled to be the master with mechanical type, can't satisfy the modern production requirement, become the technical bottleneck of producing high-grade knitted fabric exported product, seriously restricted further developing of our province knitted textile products industry.Last century late nineteen eighties, China has 100 of Computerized flat knitting machine less thaies, other horizontal editing and releasing of Asia reach area as Hong Kong and have 1500, Taiwan Province to have 400, Korea S to have 600, Chinese straight-bar machines industry is worked as fashion and is in the foundational development stage.Through the more than ten years development, the external Computerized flat knitting machine quantity of domestic application is very many, and maximum factories just have 1600.Nearly 3 years, the average annual import Computerized flat knitting machine of China still kept the 4000-5000 platform.According to estimates, China now had surplus the Computerized flat knitting machine 30,000, manually surplus the straight-bar machines 10 ten thousand, and it is very huge that Computerized flat knitting machine replaces the potentiality of hand-machine.
Existing flat machine computerized control system, generally include processor and motion controller, processor connects human-computer interaction module, Audio Controller, file system, network controller, real time clock circuit respectively, processor adopts one chip usually, a little less than the processing power, real-time processing stability is poor.
(3) utility model content
Technical problem to be solved in the utility model is to provide the flat machine that a kind of extended capability is strong, processing capability in real time is powerful computerized control system.
Described flat machine computerized control system, comprise processor and motion controller, described processor connects human-computer interaction module, Audio Controller, file system, network controller and real time clock circuit respectively, described processor is made up of the technical grade ARM chip and the DSP real-time control system that embed linux system, and described ARM chip is communicated by letter with the DSP real-time control system through two-port RAM; Described ARM chip connects human-computer interaction module, Audio Controller, file system, network controller and real time clock circuit respectively, and described DSP real-time control system connects motion controller.
Native system adopts the ARM chip of technical grade and high-speed figure to handle (DSP) to unite and be built into a cover high-performance processor.Power by ARM9 matching embedded type Linux is finished human-computer interaction interface, file system, and network interaction, the DSP control function, the real-times such as pre-service of style require lower daily pursuits management when the storage administration of style and work.The DSP real-time control system recommends to adopt the DSP TMS320F2812 chip of a new generation of TI company, its operation dominant frequency 150MHz, and the interior peripheral hardware of the sheet that has abundant suitable control, utilize its powerful data in real time processing power mainly to be responsible for accepting the goal task that the ARM general processor issues, realize the various hard real-time controls of bottom, system state detects, and the various information of gathering when reporting machine works etc.The double-core control center pattern of this " learning from other's strong points to offset one's weaknesses " will be fit to manage the professional extensibility and outstanding highly effective the combining of hard real-time control characteristic of DSP of the general processor of things.
Described motion controller is used for the control of follow-up head topworks, roller motor, each servomotor.
Further, described ARM chip also connects flash memory card interface.Style storage reliably is the very important ring of straight-bar machines.Practice shows that the method that in the past adopts battery to make standby power supply can not keep style reliably, and retainable style total file size is limited, can not satisfy the demand that promotes day by day.Native system adopts preserves style based on non-volatile flash card, and the characteristic that its non-volatile and file system are discerned bad track has automatically fully guaranteed the reliable preservation of style.Flash card described in the utility model includes but not limited to USB flash disk, SmartMedia (SM card), Compact Flash (CF card), MultiMediaCard (mmc card), Secure Digital (SD card), Memory Stick (memory stick), XD-PictureCard (XD card) and micro harddisk (MICRODRIVE) etc.The amount of capacity of flash card can rationally be specified by the user, as long as the standard compliant standard of card can be bought outfit to market arbitrarily and get final product.Under the prerequisite that guarantees reliability, provide sufficient dirigibility with personalized.
Further, described ARM chip also connects the USB controller.Replacing the traditional soft disk drive to come input and output style file with USB interface, is the trend of IT technical development, also is to solve the flimsy effective way of floppy disk.
The utility model has adopted based on dual-CPU architecture, has both had abundant peripheral hardware extendability, integrates powerful data in real time processing power again, is applicable to the robotization control of flat machine.
(4) description of drawings
Fig. 1 is the theory diagram of the described flat machine computerized control system of embodiment.
