Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, and in particular to an intelligent control system, method, electronic equipment and storage medium for a spinning machine. Background Art

[0002] Currently, the highest-capacity spinning machine is a 96-spindle double-sided spinning machine with an annual production capacity of 60,000 tons per line. The main drive systems of the spinning machine are the godet and the spindle metering pump. The spindle metering pump's speed typically controls the amount of glue sprayed into the spinning machine, and the godet then draws the tow to produce the desired fiber fineness. The spindle metering pumps are dual-driven and controlled by a frequency converter. During operation, the speed is entered into the operating system, manually calculated, and then manually entered into the godet speed to start production. During production, two speeds are typically set: a fault speed is used during the head-up operation, and the normal speed is returned after the head-up operation is complete. During production, the viscose quality is unstable, the filter clogging rate is high, and glue leakage, spindle shortages, and spindle breakage can occur. To ensure stable production, the spinning speed of the spinning machine must be adjusted in real time to ensure a consistent glue yield and constant production capacity. There are defects in manual data input. First, the reaction time is insufficient and timely adjustments cannot be made, resulting in changes in production capacity in the middle of the production line, affecting the processing effect of the back-end equipment; second, data errors are inevitable in manual calculation and input. Serious data input errors can cause equipment accidents, and minor errors can also affect the quality indicators of finished products such as fineness and strength. Summary of the Invention

[0007] The processor is used to determine the spinning speed of the spinning machine according to the first speed or the second speed, and control the frequency converter to adjust the first speed or the second speed according to the spinning speed.

[0008] The beneficial effects of the present invention are as follows: the processor can determine the spinning line speed of the spinning machine in real time based on the first speed of the guide disk or the second speed of the spindle metering pump obtained by the speed acquisition module, and automatically control the frequency converter to adjust the first speed or the second speed through the spinning line speed. A closed-loop control is formed between the speed output by the frequency converter and the first speed or the second speed. Based on the closed-loop control, the first speed of the guide disk and the second speed of the spindle metering pump are automatically controlled to improve the accuracy of controlling the spinning line speed.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that the different speed ratios of the wire guide disc and the main metering pump result in different speed increase and decrease times, which will cause differences in linear speed during the speed increase and decrease process. The processor controls the speed through linear speed feedback, thereby realizing the function of synchronously adjusting the linear speed under different speed ratios.

[0012] Furthermore, the system further includes a godet fault detection module, a filter blockage detection module, an internal air pressure detection module, and a display module, which are respectively connected to the processor;

[0017] The display module is used to display the first alarm information, the second alarm information and the third alarm information.

[0018] The beneficial effect of adopting the above further scheme is that, based on the first torque, it is possible to judge in real time whether the wire guide disk is faulty, based on the second torque, it is possible to judge in real time whether the filter is faulty, and based on the wind pressure signal, it is possible to judge in real time whether the spinning machine is faulty. Based on the above scheme, the spinning machine fault can be judged and the operator can be informed through the corresponding alarm information to avoid a larger fault due to the fault.

[0019] Furthermore, the above system also includes a backend device connected to the processor;

[0020] The processor is also used to send the spinning line speed to the back-end device, so that the back-end device can control the spinning machine accordingly according to the spinning line speed.

[0021] The beneficial effect of adopting the above further solution is that the back-end equipment controls the spinning machine accordingly according to the spinning line speed, thereby avoiding mechanical damage to the spinning machine due to fiber pulling.

[0022] Furthermore, the above system further includes a fault recording module, which is connected to the processor;

[0023] The processor is further configured to send the first torque and the second torque when a fault occurs to the fault recording module, and send the first speed and the second speed to the fault recording module;

[0024] The fault recording module is used to store the first speed, the second speed, the first torque and the second torque when the fault occurs.

[0025] The beneficial effect of adopting the above further solution is that the first speed, the second speed, the first torque and the second torque when the fault occurs are stored by the fault recording module, which can facilitate subsequent fault judgment by maintenance personnel.

[0026] Furthermore, the system further includes an audible and visual alarm module, which is connected to the processor;

[0027] The processor is further configured to send the first alarm information, the second alarm information and the third alarm information to the sound and light alarm module so as to sound and light alarm.

[0028] The beneficial effect of adopting the above further solution is that the alarm is issued in the form of sound and light, which can more intuitively remind the staff that the spinning machine has a fault, so that the staff can handle the fault in time.

[0029] Furthermore, the processor is further configured to interlock the spinning machine window corresponding to the first torque according to the first torque before generating the first alarm information;

[0030] The processor generates a first alarm message when a failure occurs in the godet, and is specifically used to: open the spinning machine window and generate the first alarm message when a failure occurs in the godet.

[0031] The beneficial effect of adopting the above further scheme is that before determining whether the wire guide disk has a fault, the spinning machine window corresponding to the first torque can be interlocked first, and then when it is determined that the wire guide disk has a fault, the spinning machine window is opened and the first alarm information is generated, which makes it easier for the operator to deal with the fault in a timely manner.

[0049] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0050] The following describes in detail the technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems using 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 following embodiments of the present invention are described in conjunction with the accompanying drawings.

[0051] The embodiment of the present invention provides a possible implementation method, such as Figure 1 As shown, a structural diagram of a spinning machine intelligent control system 10 is provided. Figure 1 As shown in , the system may include:

[0052] A processor, a frequency converter and a speed acquisition module, wherein the processor is connected to the frequency converter, the frequency converter is respectively connected to the godet and the spindle metering pump of the spinning machine, and the speed acquisition module is respectively connected to the godet and the spindle metering pump;

[0053] A rotation speed acquisition module, used to acquire a first rotation speed of a godet of a spinning machine or a second rotation speed of a spindle metering pump;

[0054] The processor is used to determine the spinning speed of the spinning machine according to the first speed or the second speed, and control the frequency converter to adjust the first speed or the second speed according to the spinning speed.

[0055] Through the system of the present invention, the processor can determine the spinning line speed of the spinning machine in real time based on the first speed of the guide wire disk or the second speed of the spindle metering pump obtained by the speed acquisition module, and automatically control the frequency converter to adjust the first speed or the second speed through the spinning line speed. A closed-loop control is formed between the speed output by the frequency converter and the first speed or the second speed. Based on the closed-loop control, the first speed of the guide wire disk and the second speed of the spindle metering pump are automatically controlled to improve the accuracy of controlling the spinning line speed.

[0056] Optionally, the speed acquisition module may include a first code disc speed measuring element and a second code disc speed measuring element. The first code disc speed measuring element is set on the wire guide disc drive shaft to obtain the first speed, and the second code disc speed measuring element can be set on the spindle metering pump to obtain the second speed.

[0057] Optionally, a first algorithm for determining the spinning line speed based on the first rotational speed will be pre-set in the processor, and a second algorithm for determining the spinning line speed based on the second rotational speed will also be pre-set. When the processor obtains the first rotational speed, the spinning line speed will be determined according to the first algorithm. When the processor obtains the second rotational speed, the spinning line speed will be determined according to the second algorithm.

[0058] The first algorithm converts the first rotational speed into the outer diameter linear velocity of the godet. This linear velocity is the fiber running linear velocity, i.e., the spinning linear velocity. The first algorithm is reversible, meaning that the first rotational speed is changed according to the spinning speed.

[0059] The second algorithm is to calculate the amount of spinning glue based on the second speed and the glue supply of the unit metering pump, and the required fiber linear speed can be calculated based on the spinning glue amount. This second algorithm is also reversible, that is, the second speed can be changed based on the change of the fiber linear speed.

[0060] Optionally, the above-mentioned frequency converter may include a first frequency converter and a second frequency converter, and there is another connection method between the above-mentioned processor, frequency converter and speed acquisition module. For example, the wire guide disk is connected to the first code disk speed measuring element, the first code disk speed measuring element is connected to the processor through the first frequency converter, the spindle metering pump is connected to the second code disk speed measuring element, and the second code disk speed measuring element is connected to the processor through the second frequency converter.

[0061] When the processor controls the frequency converter to adjust the first speed or the second speed according to the spinning line speed, it can specifically control the first frequency converter to adjust the first speed according to the spinning line speed, or control the second frequency converter to adjust the second speed according to the spinning line speed.

[0062] Optionally, the processor may further determine the amount of rubber spun by the spinning machine based on the second speed and the speed output by the second frequency converter, wherein the linear speed of the spinning machine is fixed and the second speed determines the amount of rubber spun by the spinning machine. The spinning speed of the spinning machine may also be controlled by the first speed or the second speed.

[0063] Optionally, the above-determined spinning glue amount, spinning line speed, etc. can be displayed by a display module connected to the processor.

[0064] Optionally, the processor is further configured to determine a rotational speed deviation based on the first rotational speed and the second rotational speed, and adjust the rotational speeds of the godet and the spindle metering pump based on the rotational speed deviation.

[0065] Among them, the processor adjusts the speed of the wire guide disc and the spindle metering pump according to the speed deviation, which can be called the automatic linear speed matching function. The reason for the adjustment is: the speed ratio of the wire guide disc and the spindle metering pump is different, which may cause different speed increase and decrease times, which will cause linear speed differences during the speed increase and decrease process. The processor controls the speed through linear speed feedback and can adjust the first speed of the wire guide disc and the second speed of the spindle metering pump. The purpose is to reduce the speed deviation and realize the function of synchronously adjusting the linear speed under different speed ratios. Optionally, in the present application scheme, the first speed of the wire guide disc and the second speed of the spindle metering pump can be gradually adjusted by controlling the motor through a third frequency converter connected to the processor.

[0066] Optionally, the system further includes a godet fault detection module, a filter blockage detection module, an in-machine wind pressure detection module, and a display module, which are respectively connected to the processor;

[0067] The godet fault detection module is configured to obtain a first torque of the godet of the spinning machine and send the first torque to the processor; the filter blockage detection module is configured to obtain a second torque of the spindle metering pump of the spinning machine and send the second torque to the processor; the in-machine air pressure detection module is configured to obtain an air pressure signal of the exhaust duct of the spinning machine and send the air pressure signal to the processor;

[0068] The processor is further configured to determine whether the godet fails based on the first torque, and generate a first alarm message when the godet fails, and send the first alarm message to the display module;

[0069] and determining whether the filter fails according to the second torque, and generating a second alarm message when the filter fails, and sending the second alarm message to the display module;

[0070] and judging whether the spinning machine has a fault according to the wind pressure signal, and generating a third alarm message when the spinning machine has a fault, and sending the third alarm message to the display module;

[0071] The display module is used to display the first alarm information, the second alarm information and the third alarm information.

[0072] The specific implementation method for determining whether a godet has failed based on the first torque can be as follows: if the first torque is greater than a first set torque, the godet is determined to have failed; if the first torque is not greater than the first set torque, the godet is determined to have not failed. If the speed acquisition module is connected to the processor via a first frequency converter, the first speed acquired by the speed acquisition module can be transmitted to the processor in real time via the first frequency converter. After the first alarm is generated, the operator can inspect the godet winding to see if the godet has broken wire, tangled rollers, or other faults. If a godet has failed, a single-roller shutdown can be implemented.

[0073] Optionally, the above-mentioned processor is also used to interlock the spinning machine window corresponding to the first torque according to the first torque before generating the first alarm information; then the above-mentioned processor generates the first alarm information when the guide wire disk fails, and is specifically used to: when the guide wire disk fails, open the spinning machine window and generate the first alarm information.

[0074] That is to say, before determining whether the guide wire disk has a fault, the spinning machine window corresponding to the first torque can be interlocked first, and then when it is determined that the guide wire disk has a fault, the spinning machine window can be opened and the first alarm information can be generated, which can facilitate the operator to deal with the fault in time.

[0075] The specific implementation method for determining whether the filter is faulty based on the second torque can be as follows: when the second torque is greater than the second set torque, the filter is determined to be faulty; and when the second torque is not greater than the second set torque, the filter is determined to be not faulty. If the speed acquisition module is connected to the processor via a second frequency converter, the second speed acquired by the speed acquisition module can be transmitted to the processor in real time via the second frequency converter. The second torque can reflect the permeability of the filter. When the filter is clogged with adhesive, the system channel resistance increases. To ensure flow, the second torque also increases accordingly. When the second torque reaches or exceeds the alarm value (the second set torque), the processor generates a second alarm message. After the second alarm message is generated, the organization personnel can shut down the equipment and clean the filter.

[0076] The specific implementation method for determining whether a spinning machine has a fault based on the wind pressure signal can be as follows: when the wind pressure signal is less than the set wind pressure, the spinning machine is determined to have a fault; when the wind pressure signal is not less than the set wind pressure, the spinning machine is determined to have no fault. The above-mentioned in-machine wind pressure detection module can be set in the exhaust duct of the spinning machine. After generating the third alarm message, the third alarm message can be used to warn personnel to stay away from the equipment, interlock the spinning machine to slow down, and transmit a signal to the staff to prompt them to increase the exhaust volume. If the spinning machine is in a state of continuous low pressure, the spinning machine can be interlocked to shut down and warn personnel to evacuate the equipment site.

[0077] Optionally, the system further includes an audible and visual alarm module, which is connected to the processor;

[0078] The above-mentioned processor is also used to send the first alarm information, the second alarm information and the third alarm information to the sound and light alarm module to alarm through sound and light, which can more intuitively remind the staff that the spinning machine has a fault, so that the staff can handle the fault in time.

[0079] Optionally, the system further includes a backend device connected to the processor;

[0080] The processor is also used to send the spinning line speed to the back-end device, so that the back-end device can control the spinning machine accordingly according to the spinning line speed.

[0081] Among them, the spinning line speed finally output by the spinning is transmitted to the back-end equipment. The above-mentioned corresponding control of the spinning machine includes: the back-end equipment matches the speed according to the spinning line speed and the interlocking shutdown function, which specifically refers to the interlocking operation between the spinning machine and the back-end equipment. When the spinning line speed of the spinning machine changes or other faults occur, the interlocking back-end equipment will correspondingly reduce the speed or shut down to avoid mechanical damage to the equipment due to fiber pulling.

[0082] Optionally, the above system further includes a fault recording module, which is connected to the processor;

[0083] The processor is further configured to send the first torque and the second torque when a fault occurs to the fault recording module, and send the first speed and the second speed to the fault recording module;

[0084] The fault recording module is used to store the first rotational speed, the second rotational speed, the first torque and the second torque when the fault occurs.

[0085] The fault recording module stores the first and second speeds, as well as the first and second torques at the time of the fault, to facilitate subsequent fault diagnosis by maintenance personnel. The fault recording module can also be used to record operator actions such as spinning speed adjustment, alarm value setting, and clearing, creating a historical record.

[0086] Optionally, the display module further displays an operation interface, and the operator can control the operation of the spinning machine through the operation page.

[0087] In order to better illustrate and understand the principle of the method provided by the present invention, the solution of the present invention is described below in conjunction with an optional specific embodiment. It should be noted that the specific implementation of each step in this specific embodiment should not be understood as limiting the solution of the present invention. On the basis of the principle of the solution provided by the present invention, other implementations that can be thought of by those skilled in the art should also be considered as within the scope of protection of the present invention.

[0089] Among them, the godet drive system 9 and the spindle metering pump drive system 10 constitute the main body of the spinning machine. The inverter 6 and the inverter 7 are uniformly installed in the MCC (MOTOR CONTROL CENTER) room. The centralized control system 2 is installed in the central control room. The data connection adopts Ethernet connection. Figure 2 The middle arrow represents the direction of instruction, and the bidirectional arrow enables data interaction.

[0090] During the operation of the spinning machine, the first speed of the guide disc and the second speed of the spindle metering pump can be obtained respectively through the guide disc drive system 9 and the spindle metering pump drive system 10; the first speed is sent to the centralized control system 2 through the frequency converter 6, and the second speed is sent to the centralized control system 2 through the frequency converter 7. The centralized control system 2 determines the spinning line speed of the spinning machine according to the first speed and the second speed through a pre-set algorithm, and then controls the frequency converter 6 and the frequency converter 7 to adjust the first speed and the second speed according to the spinning line speed so that the spinning line speed meets the working requirements of the spinning machine, that is, under what circumstances is the fault spinning speed and under what circumstances is the normal spinning speed. The centralized control system 2 can also send the spinning line speed to the back-end equipment so that the back-end equipment can perform corresponding control on the spinning machine according to the spinning line speed, including but not limited to speed matching and interlocking shutdown functions.

[0091] While adjusting the first and second speeds, the first torque of the godet can be obtained through a godet fault detection module, and the second torque of the spindle metering pump can be obtained through a filter blockage detection module. The godet fault detection module can be provided in the godet drive system 9, and the filter blockage detection module can be provided in the spindle metering pump drive system 10. The air pressure signal of the spinning machine's exhaust duct is obtained through an in-machine air pressure detection module. The first torque, second torque, and air pressure signals are transmitted to the centralized control system 2.

[0092] The centralized control system 2 determines whether the godet has failed based on the first torque and, if so, generates a first alarm message and sends it to the display module. The centralized control system 2 can also determine whether the filter has failed based on the second torque and, if so, generates a second alarm message and sends it to the display module. The centralized control system 2 can also determine whether the spinning machine has failed based on the wind pressure signal and, if so, generates a third alarm message and sends it to the display module. Different handling strategies can be used for different failures, as described above and will not be repeated here.
