They are used together with the embodiments of the present invention to explain the technical solutions of the present invention, and do not constitute a limitation on the technical solutions of the present invention.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0020] It is understandable that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0021] Knitting machines consist of an upper needle plate and a lower needle plate. Through the cooperation of the upper and lower needle plates, knitting machines can knit different patterns on fabrics. If any needle in the upper needle plate or any needle in the lower needle plate malfunctions, it will lead to errors in pattern knitting. Currently, needle malfunctions in the upper and lower needle plates can only be judged manually, which is inefficient and affects production efficiency.
[0022] Based on this, embodiments of this application provide a knitting machine, a control method, an apparatus, and a medium. After acquiring the pattern to be knitted, the preset needle ejection sequence of the upper and lower needle plates can be determined. If the actual needle ejection sequence of the upper and lower needle plates does not match the preset needle ejection sequence, it indicates a malfunction in the upper and / or lower needle plates. Therefore, based on the actual and preset needle ejection sequences, the first needle ejection condition of the upper needle plate and the second needle ejection condition of the lower needle plate can be determined to judge the needle malfunction. Then, based on the first and second needle ejection conditions, the working state of the knitting machine can be controlled, which can effectively improve the efficiency of needle malfunction judgment.
[0023] Firstly, referring to Figure 1 , Figure 1 A detailed flowchart of the control method for a knitting machine provided in the embodiments of this application includes, but is not limited to, the following steps: Step S100: Obtain the pattern to be knitted, and determine the preset needle output sequence of the upper and lower needle plates according to the pattern to be knitted; Step S200: According to the preset needle ejection sequence, control the upper needle plate and the lower needle plate to eject needles, and obtain the actual needle ejection sequence; Step S300: Determine the first needle exit situation of the upper needle plate and the second needle exit situation of the lower needle plate according to the actual needle exit sequence and the preset needle exit sequence; Step S400: Control the working state of the knitting machine according to the first needle exit situation and the second needle exit situation.
[0024] It is understandable that the pattern on the fabric is determined by the needle release order of the upper and lower needle plates. Different patterns correspond to different needle release orders. If the first needle in the upper needle plate and / or the second needle in the lower needle plate malfunctions (missing a needle or the needle breaks), it will cause a deviation between the actual knitted pattern and the pattern to be knitted. Therefore, after obtaining the pattern to be knitted, the preset needle release order of the upper and lower needle plates can be determined. If the actual needle release order of the upper and lower needle plates does not match the preset needle release order, it indicates that the upper and / or lower needle plates are malfunctioning. Therefore, after determining the preset needle output sequence, the upper and lower needle plates are controlled to output needles according to the preset sequence, and the actual needle output sequence is obtained. Then, based on the actual and preset needle output sequences, the first needle output situation of the upper needle plate and the second needle output situation of the lower needle plate are determined, thereby judging the needle fault. The first needle output situation indicates whether there is a fault in the upper needle plate, and the second needle output situation indicates whether there is a fault in the lower needle plate. Based on the first and second needle output situations, the working state of the knitting machine is controlled, which can effectively improve the efficiency of needle fault judgment.
[0025] It should be noted that the upper needle plate includes multiple first needles arranged in a first order, and the lower needle plate includes multiple second needles arranged in a first order. However, not all first and second needles are functional. In actual use, some first and / or second needles may be faulty and unusable. Therefore, a first target needle can be identified from among the multiple first needles, and a second target needle can be identified from among the multiple second needles. Based on the pattern to be knitted, the first target needle, and the second target needle, the preset needle release order of the upper and lower needle plates is determined. The first target needle is the non-faulty needle among all the first needles, and the second target needle is the non-faulty needle among all the second needles. By determining the preset needle release order of the upper and lower needle plates based on the pattern to be knitted, the first target needle, and the second target needle, faulty needles in the preset needle release order can be avoided.
[0026] Specifically, the fault status of each first needle is obtained in a first order, and the first needle in the first order that is in a non-faulty state is determined as the first target needle; the fault status of each second needle is obtained in a first order, and the second needle in the first order that is in a non-faulty state is determined as the second target needle.
[0027] It is understandable that the acquisition of the actual needle output sequence is real-time, meaning that the comparison between the actual needle output sequence and the preset needle output sequence is performed in real-time during the knitting machine's operation. For example, if a fault is detected in the upper needle tray and / or lower needle tray based on the first and second needle output situations during knitting machine operation, the knitting machine can be stopped and a fault alarm can be triggered, improving the efficiency of fault diagnosis. Specifically, the knitting machine can send information about a fault in the upper needle tray and / or lower needle tray to the control terminal connected to the knitting machine; it can also send information about a fault in the upper needle tray and / or lower needle tray to the user's mobile device based on pre-set contact information on the user's mobile device. This information may include, but is not limited to, SMS alerts and telephone voice alerts; the knitting machine can also directly issue audible warning signals or optical prompts when sending information about a fault in the upper needle tray and / or lower needle tray.
[0028] It should be noted that if the actual sequence of the upper needle tray equals the preset sequence, the first needle exit condition of the upper needle tray is considered normal; or, if the actual sequence of the upper needle tray does not equal the preset sequence, the first needle exit condition is considered a fault. Similarly, if the actual sequence of the lower needle tray equals the preset sequence, the second needle exit condition of the lower needle tray is considered normal; or, if the actual sequence of the lower needle tray does not equal the preset sequence, the second needle exit condition is considered a fault. Specifically, if the first needle exit condition indicates an upper needle tray fault and the second needle exit condition indicates a lower needle tray normal operation, the knitting machine can send an upper needle tray fault alarm message; if the first needle exit condition indicates an upper needle tray normal operation and the second needle exit condition indicates a lower needle tray fault, the knitting machine can send a lower needle tray fault alarm message; and if both the first and second needle exit conditions indicate an upper needle tray fault and a lower needle tray fault, the knitting machine can send both upper and lower needle tray fault alarm messages. Sending different fault messages based on different fault conditions improves the efficiency of fault location for users.
[0029] Furthermore, the needle ejection sequence of the upper needle plate and the lower needle plate should be staggered, meaning that only one needle plate ejects needles at any given time. For example... Figure 2 As shown, Figure 2 This is a schematic diagram illustrating the actual needle ejection sequence of the upper and lower needle trays provided in an embodiment of this application. In the preset needle ejection sequence, the upper needle tray does not eject needles at times 4 and 5, while the lower needle tray ejects needles at times 4 and 5. Figure 2At times 3 and 4, both the upper and lower needle beds emerge simultaneously, indicating a malfunction in the knitting machine at those times. Since needles emerge one hour ahead of times 4 and 5 at times 3 and 4, the needle bed error can be considered to be one needle position ahead of the lower needle bed. The calculation of the needle bed error value requires that the actual sequence of the upper needle bed equals the preset sequence, or the actual sequence of the lower needle bed equals the preset sequence. If neither the actual sequence nor the preset sequence equals, the knitting machine will not calculate the needle bed error value. After calculating the needle bed error value, the fault alarm message sent by the knitting machine can include it. For example, if the first needle emergence situation indicates an upper needle bed malfunction and the second needle emergence situation indicates a normal lower needle bed, then the needle bed error value of the upper needle bed is calculated based on the actual sequence of the upper and lower needle beds, and the upper needle bed fault alarm message sent by the knitting machine includes the upper needle bed error value.
[0030] Secondly, referring to Figure 3 This application provides an operation control device 300, including a memory 310, a processor 320, and a computer program stored in the memory 310 and executable on the processor 320. The processor 320 executes the program to implement the knitting machine control method of the first aspect embodiment above, for example, executing... Figure 1 Method steps S100 to S400.
[0031] The memory 310, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs, including the knitting machine control method in the above embodiments of this application. The processor 320 implements the knitting machine control method in the above embodiments of this application by running the non-transitory software program and instructions stored in the memory 310.
[0032] The memory 310 may include a program storage area and a data storage area.

Furthermore, the memory 310 may include a high-speed random access memory 310, and may also include non-transitory memory 310, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. It should be noted that the memory 310 may include remotely located memories 310 relative to the processor 320, and these remote memories 310 can be connected to the terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.
[0033] Thirdly, this application provides a knitting machine that, after acquiring the pattern to be knitted, can determine the preset needle ejection sequence of the upper and lower needle beds. If the actual needle ejection sequence of the upper and lower needle beds does not match the preset needle ejection sequence, it indicates a malfunction in the upper and / or lower needle beds. Therefore, based on the actual and preset needle ejection sequences, the first needle ejection situation of the upper needle bed and the second needle ejection situation of the lower needle bed can be determined to judge the needle malfunction. Furthermore, based on the first and second needle ejection situations, the working state of the knitting machine can be controlled, effectively improving the efficiency of needle malfunction judgment.
