Abstract
The utility model relates to a computerized flat knitting machine control device using a universal serial bus (USB). The device comprises an upper computer and a lower computer; a first USB controller is arranged in the upper computer; a second USB controller is arranged in the lower computer; and data are transmitted between the upper computer and the lower computer by adopting the USB. The pattern data transmission function inside a flat knitting machine is realized by adopting the USB, and the data transmission reaches 12Mbits/s; and the device meets the requirement of a flat knitting machine control system, has good instantaneity and strong interference resistance, and reduces the wire connection work quantity.
Description
Technical field
The utility model relates to the Computerized flat knitting machine control device, particularly relates to a kind of Computerized flat knitting machine control device that usb bus transmits inner pattern data of using.
Background technology
Computerized flat knitting machine is a kind of intelligentized Knitting Machinery, is used to weave sweater etc., the huge market demand.Along with electronic technology and development of computer, Computerized flat knitting machine also changes the full-automatic type of computer into gradually by the mechanical arm ejector half, and the function of straight-bar machines is also in continuous increase simultaneously.Problems such as the inner pattern data transmission of existing straight-bar machines mostly is the PC parallel bus greatly, thereby it is not strong to have anti-interference, and the short and line quantities of communication distance is big.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Computerized flat knitting machine control device of using usb bus, and very strong anti-interference is arranged, and has reduced the line quantities.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Computerized flat knitting machine control device of using usb bus is provided, comprises host computer and slave computer, be provided with a USB controller in the described host computer; Be provided with the 2nd USB controller in the described slave computer; Adopt usb bus to carry out data transfer between described host computer and the slave computer.
Described host computer adopts the ARM chip; Described slave computer adopts dsp chip.
Described ARM chip is electrically connected by a parallel mode and a described USB controller; Described dsp chip is electrically connected by parallel mode and described the 2nd USB controller.
A described USB controller and the 2nd USB controller all adopt the master/slave controller of usb bus.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: adopt usb bus to realize the inner pattern data propagation function of straight-bar machines, the transmission data are up to 12Mbits/s, satisfy the requirement of straight-bar machines control system, real-time is good, strong interference immunity and reduced the line quantities.
Description of drawings
Fig. 1 is a system global structure synoptic diagram of the present utility model;
Fig. 2 is a hardware line graph of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present utility model relates to a kind of Computerized flat knitting machine control device of using usb bus, as shown in Figure 1, comprises host computer and slave computer, is provided with a USB controller in the described host computer; Be provided with the 2nd USB controller in the described slave computer; Adopt usb bus to carry out data transfer between described host computer and the slave computer.Wherein, host computer is responsible for man-machine interface and pattern data processing; Slave computer is responsible for the coordination and the control of execution module, the control command of host computer is sent to the execution module of correspondence.
The hardware connection layout of usb bus as shown in Figure 2.Because the selected host computer of the design adopts the ARM chip of LPC2294 model, slave computer adopts the dsp chip of TMS320LF2407, and ARM chip and dsp chip all are electrically connected with the USB driving governor in pcb board by parallel mode.The USB controller that links to each other with the ARM chip adopts the master/slave controller of high speed USB bus of ISP1161A1 model, and one of them is used for the peripheral hardware of preserving the pattern data file is carried out read-write operation, and other one main one from being used for the data communication work with slave computer; The USB controller that links to each other with dsp chip adopts the master/slave controller of high speed USB bus of ISP1161A1 model equally, wherein, one main one from being used for the data communication work with host computer, can satisfy the inside pattern data delivery request of Computerized flat knitting machine control system fully.
Because receiving, the straight-bar machines operating state data has unpredictability, when having data to come is all determined by the slave computer duty, waste very much the processor time with cyclic query, be afraid of to miss data again, so adopt interrupt mode to receive with the method for regularly inquiry.Will cause loss of data if the data that receive can not in time be handled,,, handle again in the time of idle by the time in case the data of receiving are just deposited in buffer zone immediately for fear of loss of data.
Pattern data receives and sends method and receives just on the contrary, promptly deposits the data that will send in transmitter register in, starts then to send.The transmission that the processor A RM chip that the utility model is selected and the USB control register of dsp chip have been opened up in data-carrier store and accept buffering and post the district sends buffering and posts in the district so will selectively deposit data in according to the actual conditions of buffer zone when sending.
