After the weaving machine is put into use in a workshop, a craftsman with a password changes the patterns and designs new patterns by self-weaving, which meets the characteristics of simple and clear operation and easy operation and can perfectly control all functions of the multi-arm halter weaving machine.

The PLC control system 1 is connected with a user self-woven pattern module 2. The PLC control system 1 is connected with a palm plate position detection module 6. The PLC control system 1 is connected to an error indicator module 601. The PLC control system 1 is connected with a pattern data output module 5. The PLC control system 1 is connected with a plain palm execution module 7.

The circuit can facilitate the HMI touch screen to input operation instructions through the combination of the PLC control system 1 and the HMI touch screen, and the PLC control system 1 can effectively execute the operation instructions to control the multi-arm halter knitting machine to be in a working state.

The pattern selection module stores dozens of patterns, is convenient to operate and select knitting parameters, can also implement the user self-knitting function through the user self-knitting pattern module 2, and is convenient for technologists to design and develop new sample-making varieties.

The HMI touch screen can display the running state and the fault information of the whole system, so that people can know the state of the whole system better and the electronic dobby loom which is more intuitive for people is facilitated.

The PLC control system 1 can implement comparison instructions and transmission instructions, and the PLC control system 1 is combined with a pattern data memory for use, so that the structure of a program is simplified, and the reliability of program operation is ensured.

The expansion module can also be connected with other detection devices, so that the applicability is improved.

For example: a, B two pulse signals are taken at a certain proper position of a main shaft of the electronic dobby loom, and whether the main shaft rotates forwards or backwards can be judged according to the sequence of A, B two pulse signals; if the A phase pulse is ON and the B phase pulse is turned from OFF to ON (rising edge), the counting is positively increased; if the A phase pulse is ON, the B phase pulse is turned from ON to OFF (falling edge), the counting is reversed and reduced; therefore, the automatic bidirectional counting of whether the woven pattern is the step number or the step number is reduced is realized, and whether the counting accuracy directly influences the result of indexing output.

Two signals X75 and X74 of an upper dead point and a lower dead point are taken from the halter, a signal X7 is taken from the position of the eccentric wheel just after the eccentric wheel reaches the dead point, and then a signal X17 is taken from the position of the eccentric wheel about to leave the dead point, wherein the two signals X7 and X17 are used as a heald comparison signal and an electromagnetic valve output signal; these six position signals are important conditions to ensure that the solenoid valve is tightly controlled. The two position signals of the heald plate and the shuttle are mainly used for detecting whether the loom operates according to a preset program or not, and the function of detecting error shutdown is achieved.

When the main shaft rotates forwards, firstly, signals of upper dead point and lower dead point are sent, then an X7 heald plate comparison signal is sent, the heald plate in-place condition is compared with the heald plate position required by a program, if the results are different, the heald plate is considered to be in error and is stopped immediately, if the results are the same, the operation is continued, then the program is added to A, B signals, finally, an X17 signal is sent, and the position data of the heald plate in the next step is output. When the signal is inverted, X17 is used as a heald comparison signal, and X7 is used as an output signal. The purpose of this is to prohibit the next step from proceeding if the previous step is not completed correctly. Wherein the palm plate position detection module 6 and the palm executive module 7 are used for detecting the working state of the palm plate. The palm plate position detection module 6 and the palm executive module 7 respectively feed back position parameters and executive parameters to the PLC control system 1.

According to the action principle of the halter, the same state of the heald can be realized by different states of the hook; in order to ensure that the heald is controlled without undefined states, the hooks must be actuated according to a unique law of action in the same program. In the analysis and derivation process, an action sequence is found to meet the requirements and simplify the data processing of the heald plate. After the first step or jump step of starting up after each yarn threading, the heald plate of the step is in place and then is allowed to enter normal action control until the falling edge of an upper dead point signal X75, and then Z1 of a lower dead point counts firstly; thus, Z1 can only be 1 greater than or equal to Z0, otherwise the count is in error; a further benefit of this sequence of actions is: the pattern data output in the previous step is exactly the in-place state of the heald plate in the next step, a stop signal is referred, whether the heald plate is completed correctly or not can be conveniently detected by using a comparison instruction, if the palm plate cannot reach the specified position correctly, a palm plate indicator light which is not in place is lightened by using a delocalization instruction, a palm lifting image and a palm plate actual position comparison image are synchronously displayed on a screen, and the data processing of the heald plate is simplified. The data processing of the heald is performed by the plain palm execution module 7.

Storing the step of registering by a pattern data memory, and storing pattern data to be output by a top dead center by a data register of which the number is changed by the pattern data memory; z1 stores even steps, and the data register whose number is changed by it stores pattern data to be output from bottom dead center; at the bottom dead center, comparing whether the data of the pattern data memory pointed by the Z0 is consistent with the data of the actual position of the heald by using a comparison command CMP, and outputting the data of the pattern data memory pointed by the Z1 by using an MOV transmission command; at the top dead centre, the comparison command CMP is used to compare whether the data of the pattern data memory pointed to by Z1 matches the actual heald position data and the MOV transfer command output is used to output the data of the pattern data memory pointed to by Z0. Therefore, the two instructions can finish pattern data output with different steps and the detection of whether the heald plate is in place or not, programming parameters are simplified, and the possibility of weaving a plurality of patterns by the same program and self-weaving patterns by users is provided. The data registers D1000-D1599 only store the current operation pattern data, D2000-D7999 only store other pattern data, and when the pattern is changed, the data of the pattern data memory is only transmitted to D1000-D1599 by using a block transmission instruction.

Wherein the user self-programming pattern is realized by using 20 bit state setting elements to represent 20 healds in a self-programming window of the HMI touch screen, and the on/off of the bit state elements represents the high/low of the healds. The user only needs to click the bit state elements to the required high and low states at each step and then clicks the confirmation key. The PLC control system 1 can automatically judge the number of sending even steps and store the state data into the pattern data memory 3 corresponding to each step, thus realizing the self-editing function of the user.
