Description

Technical Field

[0001] The present invention relates to the technical field of general control or regulation systems, functional units of such systems, and monitoring or testing devices for such systems or units, and in particular to a dual-bus-based wireless jacquard warp knitting integrated control method and integrated control system in the field of warp knitting machine control. Background Art

[0002] Warp knitting machine control is an essential component of the warp knitting machine weaving process. The warp knitting machine control system is used to control the warp knitting equipment's traverse mechanism, warp let-off mechanism, take-up mechanism, and jacquard mechanism to complete actions. By integrating the control methods of these mechanisms into software, the warp knitting machine's integrated control operation method can be realized, ensuring that the yarn is woven according to the predetermined weaving program. By monitoring the actions of each mechanism, the stability and accuracy of the weaving process can be ensured, thereby better guaranteeing the quality of the fabric. The integrated information of the warp knitting equipment control software mainly includes the warp beam let-off amount, take-up density, comb yarn padding digital signal, and jacquard bias signal. The warp knitting machine process formats containing this information are ".wkc" and ".kmo". Before the software integrates the information, it parses the encoding of these two process formats and then performs instruction control according to the process requirements.

[0003] In the existing technology, when the transverse movement mechanism, warp feeding mechanism, pulling and winding mechanism and jacquard mechanism of the warp knitting equipment are controlled based on the split process to perform collaborative operations, due to the decentralized control, it is very easy to fail to complete the warp knitting operation well due to the confusion of process data, thereby affecting the actual operation efficiency.

[0004] At the same time, traditional jacquard control methods are mostly wired jacquard control, that is, each jacquard needle block (containing 16 jacquard needles) carries a cable, which is connected to the driver board. The control signal is transmitted from the driver board through the cable to the jacquard needle block to realize the bias control of the jacquard needle block. However, with the increasing market demand for diversification and specialization of warp knitting products, the requirements for jacquard jacquard jacquard functions are getting higher and higher. Traditional wired jacquard will seriously interfere with the yarn path of the jacquard comb yarn. At the same time, it is impossible to realize the individual design of the yarn path of the jacquard comb yarn for each half-machine gauge, which is not conducive to the development of special warp knitting varieties (such as the jacquard pulling process). More importantly, during the high-speed swinging process of the warp knitting machine, the cable of the wired jacquard will swing back and forth at high speed, increasing the swing resistance of the comb bar, which is not conducive to increasing the speed of the warp knitting machine. At the same time, the cable of the wired jacquard is prone to wear during the swinging process, resulting in an increased failure rate.

[0005] Wireless technology has been introduced into some existing jacquard mechanisms to achieve bias control of the jacquard needle block in the form of wireless transmission. However, the use of a single wireless transmission method cannot solve the problems of limited transmission stability and large time delay interference, and often reduces the coordination between different motion mechanisms of the warp knitting machine.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the embodiments, but the protection scope of the present invention is not limited thereto.

[0021] like Figure 1 As shown, the present invention relates to a wireless jacquard warp knitting integrated control method based on a dual bus, the method comprising the following steps: (1) Initialize the application interface; (2) Import process files into the application interface and analyze them; (3) Adjusting the process data obtained by analysis to make it conform to the preset rules; (4) assembling the adjusted process data into data protocols corresponding to different motion mechanisms of the warp knitting machine, and matching them to the corresponding motion mechanisms step by step; (5) After the matched data are aligned, they are output to the controller of the warp knitting machine, wherein the jacquard mechanism of the warp knitting machine is driven in a dual bus control mode; (6) Control the different motion mechanisms of the warp knitting machine to complete the action.

[0022] The following describes the specific steps.

[0023] (1) Initialize the application interface; like Figure 2 , which is a schematic diagram of the application interface in this embodiment; The present invention integrates the warp let-off (mechanism) control, slewing (mechanism) control, jacquard (mechanism) control and pulling (mechanism) control of the warp knitting machine, and completes the high integration of the wireless jacquard warp knitting machine control system based on the integrated control platform developed on the Windows system.

[0024] (2) Import process files into the application interface and analyze them; Specifically, the application interface provides a visual display of the parsed process data, and the process data can be edited and verified; The process data obtained by parsing includes warp knitting machine related information, knitting process parameters, warp knitting machine motion mechanism control parameters, hardware configuration and production management information; All of the process data are assigned to different forms of the application interface and are filled into editable label cards after being read.

[0025] The process data displayed on the application interface include but are not limited to process number, production machine model, number of combs, process height, and process width. At the same time, the platform can realize operations such as process creation, process editing, process copying, process deletion, and process loading.

[0026] The application interface also provides editable tabs for different kinematic mechanisms of the warp knitting machine, including the traverse mechanism and the warp let-off mechanism, allowing operators to more conveniently adjust and configure the warp knitting data in a visual manner. Specifically, a warp let-off adjustable form is set in the editable label card of the warp let-off mechanism of the warp knitting machine, and the warp let-off adjustable form can edit the number of horizontal rows, the warp let-off amount and the number of cycles of the segment; Figure 3 (a) shows the warp let-off of GB1, which includes four sections. The first section has 220 rows of warp let-off at 1200 mm / Rack, the second section has 260 rows of warp let-off at 1600 mm / Rack, the third section has 340 rows of warp let-off at 2200 mm / Rack, and the fourth section has 184 rows of warp let-off at 1800 mm / Rack. A transverse adjustable array is set in the editable label card of the transverse mechanism of the warp knitting machine. Any unit position in the transverse adjustable array corresponds to the transverse yarn number of a wireless jacquard bar in a transverse row. The transverse yarn number of any unit position is editable; Figure 3 As shown in (b), the lateral movement numbers corresponding to each jacquard bar at different horizontal rows can be retrieved by operation, and the starting and ending positions can also be copied; A wireless jacquard adjustable array is set in the editable label card of the jacquard mechanism of the warp knitting machine. Any unit position in the wireless jacquard adjustable array corresponds to a jacquard needle in a wireless jacquard row, and the bias signal of any unit position is editable; Figure 3 As shown in (c), the bias signals of different jacquard needles in different horizontal rows of the wireless jacquard can be flipped up, down, left, and right, and modified.

[0027] (3) Adjusting the process data obtained by analysis to make it conform to the preset rules; When adjusting the content of the editable label card, the background automatically verifies the compliance of the adjustment based on the preset rules. If it does not comply with the preset rules, a prompt will be displayed and the operator will be asked to modify it again. The preset rules herein are easily understood by those skilled in the art. They are determined by code execution. Generally speaking, the preset rules that meet the requirements include: The number of slave stations required by the jacquard comb is less than or equal to the number of controllable PCB boards in the dual-bus control mode; The pattern specifications conform to those of the warp knitting machine; The starting row position is correct; The spindle is at zero position; The jacquard offset angle meets the preset value; The sum of the number of rows in the let-off sections is equal to the total number of rows; The digital traverse yarn inlay meets the requirements of the process form; The traverse, let-off and total number of jacquard rows are consistent.

[0028] (4) assembling the adjusted process data into data protocols corresponding to different motion mechanisms of the warp knitting machine, and matching them to the corresponding motion mechanisms step by step; Here are the following examples, in actual application, the data can be adjusted to suit the model; Specifically, the process data protocol of the Jacquard mechanism is shown in Table 1. Table 1 Process data protocol of Jacquard mechanism Frame categories Frame subclass Valid Bytes Comb Total number of rows Current row Offset times Bias signal 0X20 0X22 Not fixed 1~b 1~20000 1~20000 p 0 or 1 Byte0 Byte1 Byte2~3 Byte4 Byte5~6 Byte7~8 Byte9 Byte10~n The length of the process data packet corresponding to the Jacquard mechanism is L1=4+6+a*2*2*p, where "4" corresponds to the number of bytes occupied by the frame major category, frame minor category, and valid bytes, "6" corresponds to the sum of the number of comb number bytes, the total number of horizontal column bytes, the current number of horizontal column bytes, and the number of offset bytes, and "a*2*2*p", where a is the number of Jacquard repeaters corresponding to any bus, and p is the offset number of any Jacquard comb, and "2" means that each Jacquard repeater occupies 2 bytes, and the total number of bytes is doubled under dual buses.

[0029] The process data protocol of the transverse mechanism is shown in Table 2. Table 2 Process data protocol of the transverse mechanism Frame categories Frame subclass Valid Bytes Comb Total number of rows Traverse signal 0X30 0X32 Not fixed 1~b 1~20000 Yarn number (1-0-1-2 / 1-2-1-0 / ……) Byte 0 Byte1 Byte2~3 Byte4 Byte5~6 Byte7~n The length of the process data packet corresponding to the slewing mechanism is L2=4+3+h*d*L, where h is the height of the slewing process pattern, d is the number of needle beds of the warp knitting equipment, and L is the digital length of the slewing yarn. "4" corresponds to the number of bytes occupied by the frame major category, frame minor category, and valid bytes, and "3" corresponds to the sum of the number of bytes of the comb number and the total number of bytes of the course. In the horizontal shift signal, the positions of the horizontal shift yarn movement include the front of the front needle bed needle, the back of the front needle bed needle, the front of the rear needle bed needle, and the back of the rear needle bed needle. Taking "1-0-1-2" as an example, "1-0" means the front needle bed needle pad yarn moves from position 1 to position 0, "0-1" means the back needle bed needle pad yarn moves from position 0 to position 1, "1-2" means the back needle bed needle pad yarn moves from position 1 to position 2, and protocol 2-1 means the front needle bed needle back pad yarn moves from position 2 to position 1. One horizontal row ends and the next horizontal row movement is carried out.

[0030] The process data protocol of the let-off mechanism and the pulling mechanism is shown in Table 3. Table 3 Process data agreement of let-off mechanism and pulling mechanism Frame categories Frame subclass Valid Bytes Axis number Total number of rows Starting row Number of segments 0X40 0X42 Not fixed 0~S 1~20000 1 N Byte0 Byte1 Byte2~3 Byte4 Byte5~6 Byte7~8 Byte9 Furthermore, Table 4 and Table 5 are the data protocols of the pulling mechanism (axis number 0) and the warp let-off mechanism (axis numbers 1~S), respectively. Table 4 Data protocol of the pulling mechanism Paragraph 1 row Density of the first stage …… Nth segment pulling row Nth segment density course course / inch …… course course / inch Byte10~11 Byte 12~15 …… Byte6N+4~Byte6N+5 Byte6N+6~Byte6N+9 Table 5 Data protocol of the warp delivery mechanism Paragraph 1 row Warp let-off amount for the first section …… Nth section of warp let-off row Warp let-off in section N course mm / Rack …… course mm / Rack Byte10~11 Byte 12~15 …… Byte6N+4~Byte6N+5 Byte6N+6~Byte6N+9 The length of the process data packet corresponding to the warp feed mechanism and the pulling mechanism is L3=4+6+N*6, where "4" corresponds to the number of bytes occupied by the frame major category, frame minor category, and valid bytes, and the added item "6" corresponds to the sum of the number of bytes of the axis number, the total number of bytes of the horizontal column, the number of bytes of the starting horizontal column, and the number of bytes of the segment number; the "6" in "N*6" refers to the number of bytes contained in the segment corresponding to each axis, and N is the number of segments corresponding to each axis.

[0031] (5) After the matched data are aligned, they are output to the controller of the warp knitting machine, wherein the jacquard mechanism of the warp knitting machine is driven in a dual bus control mode; like Figure 4 As shown, the process data of different motion mechanisms are output to the controller based on timing alignment, and the controller parses the motion information to obtain the motion information code, which is sent to the axis modules of different motion mechanisms in series through the bus.

[0032] In the present invention, the controller is connected to the warp let-off mechanism drive controller, the traverse mechanism drive controller and the pulling mechanism drive controller via a bus through an integrated control card to achieve control coordination and is connected to the jacquard (drive) controller, such as Figure 5As shown, the jacquard (drive) controller is connected to the two input ends of the communication adapter board through two buses (a first bus and a second bus), and the output end of the communication adapter board corresponding to each input end is connected to a different slave station; in this process, the unit address of the wireless jacquard needle block 1 of each wireless jacquard comb corresponding to the editable label card and the total number of jacquard bus units are obtained. After the correspondence, any wireless jacquard needle block 1 is configured to the slave station corresponding to the first bus or the second bus. Generally speaking, the first bus and the second bus respectively control the wireless jacquard needle blocks 1 with odd and even serial numbers.

[0033] Furthermore, in order to better control more precise movements, an independent address code is assigned to each jacquard guide needle 3 corresponding to each slave station of the first bus and the second bus, and the position control of a single guide needle 3 is realized based on the slave station; specifically, each slave station (jacquard needle block 1) is controlled by the first bus or the second bus, and position control is realized inside the slave station at the same time, such as through register bit mapping within the slave station to realize the control of a single guide needle 3. In order to better realize control, time-sharing activation can be realized in each slave station according to the odd or even serial number of the guide needle 3.

[0034] (6) Control the different motion mechanisms of the warp knitting machine to complete the action; In the present invention, when it comes to the cooperative operation of modular warp knitting machines, since a data interaction mode of bus transmission and wireless transmission is adopted, and considering that the speeds of bus transmission and wireless transmission are usually different, an error compensation model is constructed for the electronic slewing motion; like Figure 6 As shown in the figure, the backbone network of the error compensation model is BiLSTM, which includes several bidirectional LSTM units connected in sequence. Here, two are taken as an example. A self-attention module and a fully connected layer are set at the output of each LSTM in each bidirectional LSTM unit. A cross-attention module is set between adjacent fully connected layers, and the output of the previous cross-attention module is associated with the output of the next cross-attention module to establish a cross-level feature transfer channel, preserving the details of the underlying sensors while integrating high-level abstract features. In this setting, bidirectional LSTM units are used for basic time series feature extraction, and the unidirectional LSTM output end of the bidirectional LSTM unit self-attention focuses on key time points in that direction, such as the sudden change in the current of the feed motor. In particular, the first bidirectional LSTM unit is used to obtain instantaneous anomalies, and the second bidirectional LSTM unit focuses on progressive faults, such as position (angle) offset caused by wear. The cross-attention module realizes feature interaction between sensors, such as fusing the correlation between tension signals and vibration signals, and realizes system-level coupling through cross-layer feature transfer. Finally, the fully connected layer realizes feature space transformation. The error value to be compensated is output through linear output (feedforward compensation), the abnormal probability of the current state is output through sigmoid (to achieve graded warning), and the strategy (executable operation instructions) can be output through softmax. That is, there are three output heads. The data for training the error compensation model is obtained from feedback data of different guide bar slewing motion mechanisms of the warp knitting machine, and based on the error time between the feedback data and the planned data, combined with the slewing angle of the warp knitting machine, a data set of electronic slewing hysteresis angle within a time window of a preset length is obtained. The length of the time window can be set by those skilled in the art. The acquisition of time series data within the time window can be more conducive to the prediction of the error. training the error compensation model with a data set; The loss function here is associated with regression loss, abnormal probability classification loss, action classification loss, and constraint loss. This is easy for those skilled in the art to understand, and those skilled in the art can formulate specific loss functions based on their needs.

[0035] After the training is completed, feedback data within a time window of a preset length is obtained, and an error compensation prediction value is obtained based on the error compensation model to perform active error compensation.

[0037] In the present invention, the application interface provides functions including but not limited to importing process files, background analysis, and sending the analyzed process data to the controller using the TCP / IP communication protocol. After the process data is encoded, it is output to the controller by the interface unit, and the warp feeding (mechanism), lateral movement (mechanism) and pulling (mechanism) movements are controlled in bus mode, and the jacquard (mechanism) movement is controlled by a dual bus.

[0038] The integrated control system includes a main control thread and a feedback thread; In actual application, the main control thread controls the real-time control instructions such as the wireless jacquard bias signal transmission, the electronic sliding yarn motion curve planning, and the electronic warp let-off multi-stage let-off switching; The feedback thread reads the underlying wireless jacquard status information, reads the electronic slewing feedback analog quantity, reads the electronic let-off feedback pulse and other real-time monitoring information; The main control thread and the feedback thread adopt different thread parallel modes to achieve synchronous execution.

Any of the wireless jacquard needle blocks 1 is set in conjunction with each group of electrical contact points 4.

[0040] Correspondingly, if Figure 9 As shown, the electrical contact points 4 include, from top to bottom, a drive power interface, a communication power interface, and a communication interface. In actual application, spring pins are provided on the jacquard needle block 1 to electrically connect with the electrical contact points 4.
