Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and in particular to a method and related equipment for handheld detection of Jacquard needles. Background Technology

[0002] When the Jacquard needle blocks used in textile warp knitting machines malfunction, maintenance personnel have difficulty accurately identifying the faulty unit. They need to remove the Jacquard needle blocks from the guide bar, then connect each Jacquard needle block in series with a microammeter, apply a 200VDC voltage, and test the current value in both forward and reverse directions to make a judgment. This requires a long machine repair time.

The scope of this application is limited only by the appended claims.

[0035] The following is combined with Figures 1-3 This application describes a method for handheld detection of Jacquard needles according to exemplary embodiments of the present application. It should be noted that the following application scenarios are shown only to facilitate understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in any way. Rather, the embodiments of the present application can be applied to any applicable scenario.

[0036] In one embodiment, this application also proposes a method for handheld detection of Jacquard needles. Figure 1 A schematic flowchart illustrating a method for handheld detection of a Jacquard needle according to an embodiment of this application is shown. Figure 1 As shown, this method is applied to a detector, including:

[0037] S101, receive a needle movement request message sent by the user, wherein the needle movement request message includes instructions to measure the current of several Jacquard needles respectively.

[0038] In one approach, the detector obtains the user's needle movement requirements via a touchscreen and buttons, taking a 15-needle Jacquard needle as an example. The operator wants to configure the formula for needles 1-15, specifying whether each needle is in a "positive," "negative," or "release" state; for example, the operator wants needle 1 to be positive, needle 2 to be negative, needles 3-13 to be released, and needles 14-15 to be negative.

[0039] By individually configuring each Jacquard pin (numbers 1-15) to three states—"forward," "reverse," and "no current"—one or more Jacquard pins can be designated to perform a specific action. Setting a faulty pin to the "no current" state eliminates interference from that pin, allowing the determination of whether the remaining pins are faulty. By setting different operating commands for each Jacquard pin, the current status of the target Jacquard pin remains unaffected regardless of whether other Jacquard pins are faulty.

[0040] S102, obtain target level data based on the needle movement demand message.

[0041] In one method, the detector only needs to use a single measurement chip to measure the current at the total current output to obtain the total current. In this embodiment, by controlling the actions of five pins (1, 2, 14, 15, 15) to block the other 11 pins, the total current of the combination of specified actions of a specified number of pins can be measured, namely the total current of the combination of actions of "pin 1 forward deflection, pin 2 reverse deflection, pins 3 to 13 release, and pins 14 to 15 reverse deflection".

[0042] Among them, pins 3 to 13 are shielded and have zero current; while the total current comes from the combined action of the five pins: pin 1 deflects forward, pin 2 deflects backward, and pins 14 to 15 deflect backward.

[0043] S103, send the target level data to the shift latch circuit, wherein the target level data includes the current state of each of the Jacquard pins.

[0044] In one approach, the detector sends several Jacquard pointer operation commands to the shift latch circuit, thereby determining the current state corresponding to the operation commands. The shift latch circuit is a circuit capable of converting input serial data into parallel output and maintaining it.

[0045] In one embodiment, a data sequence (32 data points) is sequentially input into the circuit from one input. After all the data has been input, the circuit can simultaneously output this data from 32 outputs. These 32 outputs can be connected to relays respectively, thereby simultaneously controlling the operation of 32 relays. After isolation, 32 magnetically latched miniature relays are driven, enabling their common contacts to output 0V or 200V voltage in a controlled manner. The 32 voltage outputs are respectively connected to the two ends of 15 Jacquard pins, thus providing each Jacquard pin with four different voltage outputs: "0V at both ends" (Jacquard pin is not deflected, no current flows), "200V at both ends" (Jacquard pin is not deflected), "0V-200V" (Jacquard pin is forward deflected, forward current flows), and "200V-0V" (Jacquard pin is reverse deflected, reverse current flows). These four different voltages result in four different state currents. After the currents are aggregated, the MCU uses an isolated current measurement chip to obtain the current data.

[0046] In one embodiment, the operator wants pin 1 to deflect forward, pin 2 to deflect backward, pins 3 to 13 to release, and pins 14 to 15 to deflect backward. In this case, pin 1 needs to output [200V, 0V], pin 2 needs to output [0V, 200V], pins 3 to 13 need to output [0V, 0V], and pins 14 to 15 need to output [0V, 200V]. Assuming 1 represents 200V and 0 represents 0V, the required output data sequence is [1, 0, 0, 1, 0, 0, 0, ..., 0, 0, 0, 1, 0, 1, 0, 1, 0, 1].

[0047] S104, receive the response message sent by the shift latch circuit.

[0048] In one method, the detector receives current data of each Jacquard pin and total current data of all Jacquard pins from the shift latch circuit.

[0049] S105, send the response message to the user.

[0050] In this application, a detector receives a needle movement request message sent by a user; wherein the needle movement request message includes instructions to measure the current of several Jacquard needles respectively; target level data is obtained based on the needle movement request message; the target level data is sent to a shift latch circuit; wherein the target level data includes the current state of each of the several Jacquard needles; a response message is received from the shift latch circuit; and the response message is sent to the user. This application, by setting different operation instructions for each Jacquard needle, ensures that the acquisition of the current state of the target Jacquard needle is not affected regardless of whether other Jacquard needles are faulty.

[0051] Optionally, in another embodiment based on the method described above in this application, receiving the user's needle-feeding request message (S101) includes:

[0052] Receive user commands for operating several Jacquard needles;

[0053] The operating instructions for several Jacquard needles may be the same or different.

[0054] In one embodiment, by pre-setting the current state, the detection of each Jacquard needle can be better performed. By setting different operating instructions for each Jacquard needle, the acquisition of the current state of the target Jacquard needle will not be affected regardless of whether other Jacquard needles are faulty.

[0055] Optionally, in another embodiment based on the method described above in this application, such as Figure 2 As shown, sending the target level data to the shift latch circuit (S103) includes:

[0056] S201. Send the operation instructions of the plurality of Jacquard pins to the shift latch circuit;

[0057] S202. Determine the current state corresponding to the operation command.

[0058] In one embodiment, the detector only needs to use a single measurement chip to measure the current at the total current output to obtain the total current. In this embodiment, by controlling the actions of five needles (1, 2, 14, 15, 15) to block the other 11 needles, the total current of the combination of specified actions of a specified number of needles can be measured, namely the total current of the combination of actions of "needle 1 forward deflection, needle 2 reverse deflection, needles 3 to 13 release, and needles 14 to 15 reverse deflection".

[0059] Among them, pins 3 to 13 are shielded and have zero current; while the total current comes from the combined action of the five pins: pin 1 deflects forward, pin 2 deflects backward, and pins 14 to 15 deflect backward.

[0060] Optionally, in another embodiment based on the method described above in this application, determining the current state corresponding to the operation command includes:

[0061] The current state includes at least one of positive, reverse, or no current.

[0062] In one embodiment, by pre-setting the current state, the detection of each Jacquard needle can be better performed. By setting different operating instructions for each Jacquard needle, the acquisition of the current state of the target Jacquard needle will not be affected regardless of whether other Jacquard needles are faulty.

[0063] In this application, the detector receives a needle movement request message sent by the user; wherein the needle movement request message includes instructions to measure the current of several Jacquard needles respectively; target level data is obtained based on the needle movement request message; the target level data is sent to the shift latch circuit; wherein the target level data includes the current state of each of the several Jacquard needles; a response message is received from the shift latch circuit; and the response message is sent to the user. This application allows for pre-setting of several Jacquard needles, for example, each needle can be individually configured with three states: "forward," "reverse," and "no current," thus enabling the specific action of one or several needles; a faulty needle can be configured to the "no current" state, thereby eliminating interference from that needle and determining whether the remaining needles are faulty. Regardless of whether other Jacquard needles are faulty, it does not affect the acquisition of the current state of the target Jacquard needle.

[0067] The transmitting module 303 is configured to transmit the target level data to the shift latch circuit and to transmit the response message to the user.
