[0030] The specific embodiments of the present invention will be described below with reference to the drawings.
[0031] Reference figure 1. A control system of a pull-wire jacquard includes an industrial computer 1, a pull-wire jacquard controller 2, a pull-wire jacquard repeater 6, a proximity switch 3, a pull-wire jacquard driver 4, and a pull-wire jacquard 5. The industrial computer 1 is an ordinary industrial control computer equipped with corresponding puller jaka driver software. The industrial computer 1 is provided with a data communication interface 11 that can communicate with the puller jaka controller 2 and The data communication interface 12 for reading Jacquard craft files, wherein the data communication interface 11 is an RS232 data communication interface, and the data communication interface 12 is a USB data communication interface. The proximity switch 3 is used to determine the position information of the main shaft of the warp knitting machine and send the position information to the wire jacquard controller 2. The pull-wire Jacquard controller 2 is provided with a data communication interface 21 for receiving the Jacquard process data downloaded from the industrial computer 1. The data communication interface 21 is also an RS232 data communication interface, and the data communication interface 21 is connected to the data The communication interface 11 is connected. The wireline jacquard repeater 6 is used to convert the process data transmitted from the wireline jacquard controller 2 into control data and transmit the wireline jacquard driver 4. The puller jacquard driver 4 is used to receive the control data transmitted by the puller jacquard repeater 6 and drive the puller jacquard 5 to act to form a pattern on the cloth.
[0032] Reference figure 1. The wireline jacquard controller 2 and the wireline jacquard repeater 6 are connected by an optical fiber 7, and the optical fiber 7 is set for communication, which not only greatly improves the data transmission speed of the system, but also has good stability and anti-interference. Strong ability. In addition, by integrating optical fiber communication technology, this system does not need to use many wires for data transmission like the original system. To a certain extent, it can avoid failures caused by disconnection and breakage, and can avoid jacquard caused by failures. Wrong loss.
[0033] A 32-bit ARM embedded processor is provided in the puller jaka controller 2, and a 32-bit ARM embedded processor is provided in the puller jacquard repeater 6. By setting a 32-bit ARM embedded processor, It can improve the data processing performance of the cable jacquard controller 2 and the cable jacquard repeater 6. The optical fiber 7 between the cable jacquard controller 2 and the cable jacquard repeater 6 can greatly improve the system performance. Operating speed and control ability, so when adding a new jacquard, the system software and hardware do not need to be changed. In this embodiment, each pull-line jacquard controller 2 is connected to four pull-line jacquard repeaters 6 at the same time. Two wireline jacquard repeaters 6 connect and control eight wireline jacquard drives 4 at the same time (due to limited viewing space, figure 1 It does not show that each wireline jaka repeater 6 controls eight wireline jacquard drivers 4, but only one wireline jaka driver 4 is used to indicate in combination with the text content.) The relay 6 is simultaneously connected to eight wireline jacquard drivers 4, each of which drives 128 wireline jacquard drivers (due to limited viewing space, figure 1 It does not show that each puller jacquard driver 4 controls 128 puller jacquards 5 separately, but only a handful of puller jacquard 5 is used to indicate in combination with the text content. According to the applicant’s experimental debugging, The invention can support up to 4096 jacquards, so compared with the original system, the use of this system can greatly reduce the user's cost and improve the production efficiency.
[0034] Reference figure 1 with figure 2. In the present invention, the working process of the control system of the above-mentioned cable jacquard is substantially the same as the control method of the control system of the cable-drawn jacquard. Therefore, the control method of the cable jacquard will be described in detail below in conjunction with the control system of the above-mentioned cable jacquard. A control method of Jacquard, including the following steps: step a, open the driver software of Jacquard in the industrial computer 1, and read in the Jacquard process file data through the data communication interface 12. The data communication interface 12 in this step The USB data communication interface is preferred, and the process files are imported through USB, which is fast and reliable.
[0035] Step b. The industrial computer 1 downloads the Jacquard process file data obtained in step a to the wire Jacquard controller 2 through the transmission cooperation of the data communication interface 11 and the data communication interface 21, the data communication interface 11 in this step The RS232 data communication interface is adopted with the data communication interface 21, which can facilitate the transmission and control of parallel data.
[0036] Step c. After starting the mechanical part of the warp knitting machine, the proximity switch 3 obtains the position information of the main shaft of the warp knitting machine and sends the position information to the wire jacquard controller 2.
[0037] Step d. According to the position information obtained from the proximity switch 3, the wireline jacquard controller 2 reads the process file data downloaded in step b row by row in the process sequence, and sends it to the wireline jacquard repeater through optical fiber communication 6. In this step, the wireline jacquard controller 2 and the wireline jacquard repeater 6 are both equipped with a 32-bit ARM embedded processor, and in this step, the wireline jacquard controller 2 is in the running process It continuously feeds back the current operating status of the cable Jaka repeater 4 to the industrial computer 1 and displays it on the interface of the industrial computer 1.
[0038] Step e. The wireline Jaka repeater 6 converts the transferred process file data into control data, and outputs it to the wireline Jaka driver 4.
[0039] Step f. The wire jacquard driver 4 drives the wire jacquard 5 to act according to the control data obtained from the wire jacquard repeater 6 to form a pattern on the cloth surface, thereby completing a process. Step g, repeat step d to step f until the entire process is completed.
[0040] When it is necessary to perform a stop operation, the user can start the stop step, that is, click the stop operation on the input interface of the industrial computer. At this time, the industrial computer 1 sends a stop signal to the cable jacquard controller 2, and the cable jacquard control The device 2 stops the operation of step d according to the signal.
[0041] The foregoing are only specific implementations of the present invention, but the design concept of the present invention is not limited to this. Any insubstantial modification of the present invention using this concept should be an act that violates the protection scope of the present invention.
