[0001] The present application relates to the field of glove knitting machines, and in particular to a wire break detection method, electronic equipment, storage medium and program product. Background Art
[0002] A glove knitting machine is an automated equipment used to produce gloves, usually called a glove machine or glove loom. It is mainly used to knit various materials (such as cotton, wool, etc.) into gloves. There are many types of glove knitting machines, mainly including glove flat looms and glove vertical looms.
[0003] During operation, the glove knitting machine uses yarn for knitting, which may cause the thread to break due to thread quality or lint. The most commonly used thread break detection method in the market is the antenna switch method, that is, each cable corresponds to a thread spring, and all thread springs are connected to a signal end; under normal circumstances, each thread spring is not connected to the ground wire, and when the thread is broken, the thread spring pops out and connects to the ground wire.

In addition, the same machine may use multiple yarns, which are connected to the same signal terminal. If one of the yarns is broken, it is impossible to detect that one of the yarns is broken, and the exact location of the break cannot be accurately reported. In addition, if there are multiple strands of cables in a thread spring or other reasons cause the thread spring to fail to be ejected in time, no alarm will be given, and the glove knitting machine will not be able to stop due to the inability to give an alarm in time, resulting in a large number of defective finished products.

[0045] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0047] First, the terms involved in this application are explained:
[0048] Knitting glove machine: Knitting glove machine is an automated equipment used to produce gloves, usually called glove machine or glove loom. It is mainly used to knit various materials (such as cotton, wool, etc.) into gloves. There are many types of knitting glove machines, mainly including glove flat looms and glove vertical looms.
[0049] Infrared pair tube: It is the general term for the infrared emitting tube and the photosensitive receiving tube, or the infrared receiving tube, or the infrared receiving head when used together. The wavelength greater than 0.76 microns in the spectrum is called infrared.
[0050] Infrared emitting tube: It is a luminous body composed of infrared light-emitting diodes. The PN junction is made of materials with high infrared radiation efficiency (commonly gallium arsenide). The forward bias voltage injects current into the PN junction to excite infrared light. Its spectral power distribution is a central wavelength of 830-950nm. LED (Light Emitting Diode) has a positive temperature coefficient. The greater the current, the higher the temperature. The higher the temperature, the greater the current. The power of LED infrared lamp is related to the current. However, when the forward current exceeds the maximum rated value, the infrared lamp emission power decreases instead.
[0051] Figure 1 A schematic diagram of a disconnection detection device provided in this application, such as Figure 1 As shown, during the operation of the glove knitting machine, an infrared transceiver pair is used as a line measuring sensor, and the yarn works in the infrared transceiver pair. There is a one-to-one correspondence between multiple infrared transceiver pairs and multiple line transmitting tubes. Under normal circumstances, the yarn will shake continuously with the normal operation of the machine. Multiple infrared transceiver pairs detect the yarn shaking change signal. If the machine cannot detect the yarn shaking signal within the specified detection time during operation, it proves that the yarn is not working, and the feedback is that the yarn is broken, and the machine stops and alarms.
[0052] Combined with the above scenario, it can be seen that the glove knitting machine uses yarn for knitting, which may cause the thread to break due to thread quality or lint. The thread break detection method currently widely used in the market is to use an antenna switch method, that is, each cable corresponds to a thread spring, and all thread springs are connected to a signal end; under normal circumstances, each thread spring is not connected to the ground wire, and when the thread is broken, the thread spring pops out and connects to the ground wire.
[0053] The existing technology has the following problems. For example, if the thread spring is stuck and cannot be ejected due to cable quality or other reasons, no alarm will be given, resulting in a large number of waste and inferior products. In addition, the same machine may use multiple yarns, which are connected to the same signal terminal. If one of the yarns is broken, it is impossible to detect that one of the yarns is broken, and the exact location of the break cannot be accurately reported. In addition, if there are multiple strands of cables in a thread spring or other reasons cause the thread spring to fail to be ejected in time, no alarm will be given. The glove knitting machine will not be able to stop the machine due to the inability to give an alarm in time, resulting in a large number of defective finished products.
[0054] The thread break detection method provided by the present application uses an infrared transceiver pair of tubes as a thread detection sensor, so that the yarn works in the infrared transceiver pair of tubes, and multiple infrared transceiver pairs of tubes detect the yarn jitter change signal. The processor obtains the thread detection signal of the infrared transceiver pair of tubes, and determines the yarn state of the thread sending tube corresponding to the target infrared transceiver pair of tubes based on the thread detection signal analysis. The glove knitting machine can alarm in time when the thread is broken, and can accurately determine the position of the broken thread, which solves the problem in the prior art that if the thread picking spring cannot be ejected in time, there will be no alarm, and the knitting glove machine will not be able to stop due to the failure to alarm in time, resulting in a large number of defective finished products.
[0055] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0056] Figure 2 A schematic diagram of a disconnection detection method provided in this application Figure 1 , a processor used in a wire break detection device, such as Figure 2 As shown, the method includes:
[0057] S101, obtaining a line measurement signal sent by at least one target infrared transceiver pair.
[0058] The line measurement signal is used to indicate the level status of the corresponding target infrared transceiver pair within a preset period. First, determine the infrared transceiver pair to be monitored to ensure that they are in working condition and connected normally; then determine a fixed time period for monitoring the level status of the infrared transceiver pair. This period can be, for example, milliseconds, seconds or longer, depending on the application scenario and requirements, and this application does not limit it here.
[0059] It can be understood that the monitoring function in the circuit can be started and the level state of the target infrared transceiver pair can be recorded within a preset period. For example, a signal acquisition device (such as an oscilloscope, a data acquisition card, etc.) can be used to capture the line measurement signal sent by the infrared transceiver pair to ensure that the collected signal is clear and accurate and can reflect the level state changes of the infrared transceiver pair.
[0060] Specifically, the infrared transmitting tube and the infrared receiving tube are installed opposite to each other on one side of the yarn, so that their axes are perpendicular to the running direction of the yarn, and the infrared light can be directly irradiated on the yarn. At the same time, the position of the infrared transmitting and receiving tubes must be fixed to avoid displacement caused by machine vibration and other factors, which may affect the detection accuracy.
[0061] When an appropriate forward voltage is applied to the infrared transmitting tube, the electrons in the transmitting tube recombine with holes, releasing energy and radiating it in the form of infrared light. When the infrared receiving tube does not receive infrared light, it is in a cut-off state, and the reverse current is very small, almost zero. When the yarn does not block the infrared light, the infrared receiving tube receives the infrared light emitted by the infrared transmitting tube, and the photon energy is transferred to the electrons in the receiving tube, causing the electrons to transition to free electrons, thereby generating photocurrent and realizing the conversion of optical signals to electrical signals.
[0062] It should be noted that since the light intensity change caused by yarn jitter is relatively small, the generated electrical signal is also relatively weak, so it is necessary to amplify the signal through an amplifier circuit to increase the signal amplitude and signal-to-noise ratio. At the same time, in order to remove the noise and interference components in the signal, a filter circuit can also be used, such as a low-pass filter, a high-pass filter or a band-pass filter. According to the frequency characteristics of the yarn jitter signal, appropriate filter parameters are selected to filter out the noise and interference signals to obtain the line measurement signal.
[0063] S102. Determine the yarn state of the yarn transmitting tube corresponding to at least one of the target infrared transmitting and receiving tubes based on the line measuring signal.
[0064] The yarn status includes: working status and broken status.
[0065] Understandably, in the working state, when the yarn passes normally between the infrared transceiver tubes, the infrared signal will be partially blocked by the yarn, and the signal strength received by the receiving tube will have a certain change pattern. For example, due to the blocking of the yarn, the voltage output by the receiving tube may fluctuate within a relatively stable range; while in the disconnected state, there is no yarn blocking the infrared light path, and the signal strength received by the receiving tube will be significantly different from when there is yarn. Normally, the light intensity received by the receiving tube will become stronger, and the corresponding output voltage will rise to a value that exceeds the voltage range of the working state.
[0066] Specifically, one or more thresholds are set according to actual conditions to distinguish between the working state and the broken state of the yarn. For example, a signal strength threshold can be set. When the received signal strength is lower than the threshold, the yarn is considered to be in a broken state. The monitoring system analyzes the line measurement signal in real time and compares the signal strength or level state with the set threshold. That is, if the signal strength or level state meets the working state condition, the yarn is judged to be in a working state; if the signal strength or level state meets the broken state condition, the yarn is judged to be in a broken state.
[0067] It should be noted that in the actual environment, there may be some interference factors, such as light changes, electromagnetic interference, etc., which may cause fluctuations in the line measurement signal. In order to reduce misjudgment, some anti-interference measures can be adopted, such as using a filtering algorithm to process the acquired signal, etc., which will not be elaborated in this application.
[0068] A method for detecting a broken wire is provided in an embodiment of the present application. The infrared transceiver pair of tubes in the broken wire detection device detects the yarn of the corresponding wire sending tube, and the processor determines the yarn status of the corresponding wire sending tube according to the line detection signal sent by the infrared transceiver pair of tubes, so that any broken wire situation during operation can be alarmed in time, and the broken wire position can be reported accurately, thereby reducing the probability of producing defective products in the production process and improving maintenance efficiency.
[0069] Figure 3 A schematic diagram of a disconnection detection method provided in this application Figure 2 ,like Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, a disconnection detection method is described in detail, the method comprising:
[0070] S201, determine the currently running program.
[0071] The operating program is the program required for the gloves knitted by the current glove knitting machine. The corresponding operating program will be different for each glove knitting process.
[0072] S202: Based on the currently running program, determine at least one target infrared transceiver pair from a plurality of infrared transceiver pairs.
[0073] Among them, in actual use, multiple infrared transceiver pairs may not be used completely, and the specific use process can be determined according to different glove processes. By clarifying the physical position, number and connection method between each infrared transceiver pair and the control system, at least one target infrared transceiver pair that needs to be operated during this working process can be determined.
[0074] S203, obtaining a line measurement signal sent by at least one target infrared transceiver pair.
[0075] Among them, step S203 is similar to the above step S101 and will not be repeated here.
[0076] S204, for any one of the at least one target infrared transceiver pair, determine the yarn jitter of the yarn transmitting tube corresponding to the target infrared transceiver pair according to the electrical level state within a preset period.
[0077] The level state can be a high level or a low level, which can correspond to whether the infrared signal is received or not. The preset period can be used to regularly monitor the level state of the infrared transceiver pair. This period can be adjusted according to actual needs, such as monitoring once per second or every few minutes, and the level state of the infrared transceiver pair is recorded in each preset period.
[0078] It can be understood that the yarn jitter is determined according to the number and amplitude of level changes. For example, some thresholds can be set to determine the degree of jitter.
[0079] S205: When the yarn shaking situation is a shaking scene, determine that the yarn state is a working state.
[0080] Among them, the change of the level state can be linked to the yarn jitter. Yarn jitter means that the yarn exists and is in dynamic change. As long as the degree of jitter is within a reasonable range, the yarn is not completely disconnected so that the infrared light path is not blocked, or the yarn is not in a static state, resulting in the infrared light path level not changing, the yarn can be determined to be in a working state. When the level state changes frequently and the change pattern matches the expected pattern of yarn jitter, such as periodic blocking and releasing of infrared signals, it can be determined that the yarn is jittering.
[0081] It can be understood that by using an infrared transceiver tube or other sensors to continuously monitor the jitter of the yarn, data on the yarn jitter, including the jitter frequency, amplitude and duration, etc., can be collected, and the collected jitter data can be processed and analyzed.
[0082] Specifically, based on the analysis results, it can be determined whether the yarn jitter condition belongs to the expected jitter scenario. If the jitter data is within the preset normal range and does not exceed the threshold of abnormal jitter, the yarn jitter condition is considered to be a jitter scenario, and it can be inferred that the yarn is in a working state.
[0083] S206: When the yarn shaking situation is a non-shaking scenario, determine that the yarn state is a broken state.
[0084] Among them, when the yarn jitter situation is no jitter, it can be determined that the yarn has been disconnected and is no longer in a normal working state, and it has an impact on the light path between the infrared transceiver tubes and other factors.
[0085] It is understandable that the yarn jitter condition can be analyzed according to the level state in a preset period to determine whether the current yarn is in a non-jittering scenario. For example, the number of level changes and amplitude and other related indicators can be detected and analyzed. If the number of level changes is very small and the amplitude is almost zero, such as below a certain set minimum threshold, such as 1 or 2 times, the yarn can be determined to be in a non-jittering situation.
[0086] When the yarn shaking situation is determined to be a non-shaking scenario, the yarn state can be reasonably inferred to be a broken state or a stopped state, which indicates that there is a problem with the yarn during the production process and immediate measures need to be taken to repair or adjust it.
[0087] S207: Generate an error prompt and control the knitting machine to stop working.
[0088] When it is determined that the yarn state is a broken state, an error prompt is generated and the knitting machine is controlled to stop working.
[0089] It is understandable that once the yarn is determined to be in a broken state, an error prompt message is immediately generated, and the error prompt can be presented to the operator through, for example, an audible and visual alarm, a display screen, an alarm signal, etc. At the same time, the processor sends a stop working instruction to the control system of the glove knitting machine. After receiving the instruction, the control system should immediately stop all moving parts of the knitting machine to prevent further damage or accidents.
[0090] The embodiment of the present application provides a method for detecting a broken line. At least one target infrared transceiver pair is determined by the current running program, and the processor receives the line measurement signal sent by the target infrared transceiver pair. By analyzing the level state of the line measurement signal, the yarn jitter of the line transmission tube corresponding to the target infrared transceiver pair is determined, and the yarn state is determined to be a working state or a broken line state. The yarn in work can be detected according to the glove knitting process. Thus, a device can be installed with multiple sensors, and the sensor number corresponding to the corresponding yarn can be set according to the process of processing patterns of the customer's equipment. The signal of each sensor module is connected to different interfaces of the control board. The control board software performs state feedback of each sensor module bit by bit, and the yarn state that is not working is shielded and filtered. Any broken line situation during operation can be alarmed in time, and the broken line position can be accurately reported, so as to realize accurate judgment and alarm.
[0091] Figure 4 A schematic diagram of a disconnection detection method provided in this application Figure 3 ,like Figure 4 As shown, in this embodiment Figure 3 Based on the embodiment, a process of determining that the yarn state is a working state in a thread break detection method is described in detail, and the method includes:
[0092] S301, determining the jitter parameter of the yarn jitter condition.
[0093] The jitter parameter may represent, for example, jitter frequency, jitter amplitude, jitter direction, etc.
[0094] It can be understood that by counting the number of times the level state changes, the amplitude of the level change can be further analyzed. For example, if the signal is a high and low level obtained after the analog signal passes through the comparator, and the analog signals corresponding to the high and low levels have a certain range, such as the high level corresponds to 3-5V, and the low level corresponds to 0-2V, the amplitude can be determined according to the difference in analog signals when adjacent level states change, thereby determining the yarn jitter condition.
[0095] Specifically, the yarn jitter is determined according to the number and amplitude of level changes. For example, some thresholds can be set to judge the degree of jitter. If the number of level changes is less than 10 times and the amplitude is small (such as the analog signal difference is less than 0.5V), it can be judged as slight jitter; if the number of level changes is between 10-30 times and the amplitude is moderate (such as the analog signal difference is between 0.5-1V), it is judged as moderate jitter; if the number of level changes exceeds 30 times and the amplitude is large (such as the analog signal difference is greater than 1V), it is judged as severe jitter.
[0096] S302, determine whether the jitter amplitude is within a preset amplitude range; if so, execute step S303; if not, execute step S304.
[0097] The preset range of the yarn jitter amplitude can be determined according to production process requirements, yarn material, knitting machine performance, etc. The preset range can be represented by a minimum value (such as 0.5 mm) and a maximum value (such as 2.0 mm), for example.
[0098] S303, determining that the yarn state is a working state.
[0099] S304: Determine that the yarn state is an abnormal state.
[0100] Specifically, the jitter amplitude measured in real time may be compared with a preset range, the latest jitter amplitude data may be obtained from a measuring device, and the extracted data may be compared with a preset minimum value and a preset maximum value.
[0101] If the jitter amplitude is within a preset range, that is, greater than or equal to the minimum value and less than or equal to the maximum value, it is determined to be normal, that is, in working state.
[0102] If the jitter amplitude is less than the preset minimum value or greater than the preset maximum value, it is determined to be abnormal. At this time, an alarm signal can be sent to the operator or management system so that timely measures can be taken.
[0103] In a possible implementation, after acquiring a line measurement signal sent by at least one target infrared transceiver pair, a line break detection method further includes:
[0104] For any one of at least one of the target infrared transceiver pairs, determine whether the line measurement signal sent by the target infrared transceiver pair is continuously in a single level state within the preset period, and the level state includes: a low level state and a high level state;
[0105] If the line measurement signal is continuously in a low level state or a high level state within the preset period, a prompt message is generated, and the prompt message is used to indicate that the line transmission tube corresponding to the target infrared transceiver pair is in an abnormal state.
[0106] Among them, the broken thread detection adopts an infrared transceiver pair of tubes as a thread measuring sensor. The yarn works in the infrared transceiver pair of tubes. It is a high level when there is no yarn and a low level when there is yarn.
[0107] It is understandable that when using an infrared transceiver pair to monitor the yarn status, under normal circumstances, the yarn between the transceiver pair will block the infrared light, causing the line measurement signal output by the receiving tube to show a certain level change pattern, such as switching between high and low levels or fluctuating with the corresponding amplitude according to the yarn blocking situation. When the line measurement signal is continuously in a low level state or a high level state within a preset period, it is very likely that the yarn has been disconnected and no longer blocks the optical path, causing the receiving tube to continue to receive strong infrared light, or the yarn has been stationary, causing the infrared optical path to no longer change level, so that the output remains in a low level or high level state. Therefore, it can be determined that the corresponding line transmission tube is in an abnormal state at this time, and a prompt message needs to be generated to inform the relevant operation and maintenance personnel or the system for subsequent processing.
[0108] Specifically, ensure that at least one target infrared transceiver pair has been installed and configured to send and receive line measurement signals. Through these infrared transceiver pairs, line measurement signals related to the yarn state can be obtained. Secondly, for each target infrared transceiver pair, it is necessary to determine whether the line measurement signal sent by it is continuously in a low level state or a high level state within a preset period.
[0109] If the line measurement signal sent by a target infrared transceiver pair is continuously in a low level state or a high level state within a preset period, this usually means that the corresponding line sending tube may be abnormal. Such abnormal conditions may, for example, indicate that the current sensor setting is wrong or there is a missing line in the line sending tube corresponding to the target infrared transceiver pair or the yarn is broken at a certain point. In this case, a prompt message may be generated to indicate that the line sending tube corresponding to the target infrared transceiver pair is in an abnormal state.
[0110] Based on the prompt information, the operator can take appropriate measures to deal with the abnormality. For example, the operator can stop the operation of the knitting machine, check whether the wire tube and infrared transceiver tube are damaged or blocked, or whether the wire tube is short of wire and needs to be supplemented, and then perform corresponding repairs or replacements to improve production efficiency and product quality.
[0111] A method for detecting a broken wire is provided in an embodiment of the present application. The method determines the working status of the current device through yarn jitter parameters or level information of the infrared transceiver's reaction to the tube. When the jitter amplitude exceeds a preset amplitude range or is continuously in a low level state or a high level state within a preset period, the method determines that the current device is abnormal. Based on the abnormal information, blockage or other abnormal conditions can be discovered and handled, thereby improving production efficiency and product quality and reducing the probability of generating waste and defective products during the production process.
