[0054] The core of the present invention is to provide a textile drive control energy storage integrated cabinet and a textile drive control energy storage control method. This scheme adopts an integrated integrated cabinet, and the main control board, inverter, servo motor driver and power control unit are integrated in the cabinet, which reduces the volume of the electric control cabinet. In addition, an additional electric energy storage module is provided, and the power consumption of the textile machine is balanced with the rated output power of the power grid by controlling the energy storage and discharge of the electric energy storage module, which greatly reduces the impact on the power grid and reduces the operating load of the power grid.

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Please refer to Figure 1 , Figure 1 The structural diagram of a textile drive-control energy storage integrated cabinet provided by the present invention. The textile drive-control energy storage integrated cabinet comprises: a cabinet 1, an electric energy storage module 2, a main control board 3, a frequency converter 4, a servo motor driver 5, and a power control unit 6. The electric energy storage module 2, the main control board 3, the frequency converter 4, the servo motor driver 5, and the power control unit 6 are all arranged inside the cabinet 1;

[0057] The main control board 3 is used to control the frequency converter 4 and the servo motor driver 5 accordingly based on the received control instructions;

[0058] The frequency converter 4 is used to transmit electric energy of corresponding frequency to the spindle motor in the textile machine based on the control of the main control board 3;

[0059] A servo motor driver 5, used for transmitting corresponding drive signals to the servo motor in the textile machine based on the control of the main control board 3;

[0060] The power control unit 6 is used to determine the power consumption of the textile machine at the current moment, and when the power consumption of the textile machine at the current moment is less than the rated output power of the power grid, control the electric energy storage module 2 to store the AC power transmitted by the power grid accordingly; when the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid, control the electric energy storage module 2 to discharge to the textile machine accordingly.

[0061] In the present invention, considering that the control devices inside the existing combined electric control cabinet are relatively scattered, resulting in a large amount of volume being occupied, which is not conducive to practical use, the present solution adopts an integrated all-in-one cabinet, in which the main control board 3, the inverter 4, the servo motor driver 5 and the power control unit 6 are integrated in the cabinet body 1, thereby reducing the volume of the electric control cabinet. In addition, considering that in the existing integrated cabinet, although multiple control devices are integrated inside, because each control device requires power supply support from the power grid, and when the operating speed of the textile machine is different, the power consumption of each control device is different, which is easy to cause an impact on the power grid and increase the operating load of the power grid, the present scheme additionally sets up an energy storage module 2, and controls the energy storage module 2 accordingly according to the relationship between the power consumption of the textile machine and the rated output power of the power grid through the power control unit 6, so that the energy storage module 2 can store the AC power accordingly when the historical power consumption of the textile machine is less than the rated output power of the power grid, or control the energy storage module 2 to discharge to the textile machine accordingly when the historical power consumption of the textile machine is greater than the rated output power of the power grid, that is, when the power consumption of the textile machine is too high, the energy storage module 2 is controlled to supply power to the textile machine. At this time, there is no need for the power grid to provide additional power; similarly, when the power consumption of the textile machine is too low, the excess electric energy output by the power grid is stored by the energy storage module 2, which greatly reduces the impact on the power grid and reduces the operating load of the power grid.

[0062] This embodiment provides a textile drive control energy storage integrated cabinet. This solution adopts an integrated integrated cabinet, and a main control board 3, a frequency converter 4, a servo motor driver 5 and a power control unit 6 are integrated in the cabinet body 1, thereby reducing the volume of the electric control cabinet. In addition, considering that when the power consumption of the textile machine is less than or greater than the rated output power of the power grid, it will cause an impact on the power grid, so this solution additionally sets up an electric energy storage module 2, and controls the electric energy storage module 2 to store the AC power transmitted by the power grid when the power consumption of the textile machine is less than the rated output power of the power grid through the power control unit 6. When the power consumption of the textile machine is greater than the rated output power of the power grid, the electric energy storage module 2 is controlled to discharge to the textile machine accordingly, so as to balance the power consumption of the textile machine with the rated output power of the power grid, thereby greatly reducing the impact on the power grid and reducing the operating load of the power grid.

[0063] Based on the above embodiments:

[0064] As an optional embodiment, the power control unit 6 is specifically used for:

[0065] Obtaining the corresponding relationship between the operating angle of the spindle motor and the power consumption of the textile machine in one working cycle of the spindle motor;

[0066] Determine the current operating angle of the spindle motor at the current moment;

[0067] The power consumption of the textile machine at the current moment is determined according to the current operating angle and the corresponding relationship, and when the power consumption of the textile machine at the current moment is less than the rated output power of the power grid, the electric energy storage module 2 is controlled to store the AC power transmitted by the power grid accordingly; when the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid, the electric energy storage module 2 is controlled to discharge to the textile machine accordingly.

[0068] In the present invention, considering that there is a corresponding relationship between the power consumption of the textile machine and the operating angle of the spindle motor in the textile machine within a working cycle, it is necessary to first obtain the above-mentioned corresponding relationship, and then determine the current operating angle of the spindle motor at the current moment, and then the power consumption of the textile machine at the current moment can be determined according to the corresponding relationship and the current operating angle of the spindle motor. In order to balance the power consumption of the textile machine and the rated output power of the power grid, it is only necessary to control the electric energy storage module 2 to store the AC power transmitted by the power grid when the power consumption of the textile machine at the current moment is less than the rated output power of the power grid, and control the electric energy storage module 2 to discharge to the textile machine when the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid. That is, the energy storage or discharge of the electric energy storage module 2 is controlled accordingly according to the operating angle of the spindle motor, thereby ensuring the integrity and accuracy of the energy storage and discharge control process.

[0069] It should be noted that in practical applications, the corresponding relationship between the operating angle of the spindle motor and the power consumption of the textile machine is as follows: Figure 2 As shown in the figure, and in any working cycle of the main shaft motor, the total weft insertion current curve is approximately the same, so the power consumption of the textile machine can be determined according to the product of the power consumption current of the textile machine corresponding to the total weft insertion current curve and the power consumption voltage of the textile machine, that is, the total weft insertion current curve is approximately regarded as the power consumption curve of the textile machine, and Figure 2 The black straight line in the figure is the rated output current curve of the power grid, which can also be equivalent to the rated output power curve of the power grid. Therefore, when the total weft insertion current curve is lower than the rated output current curve of the power grid, it means that the electric energy provided by the power grid exceeds the electric energy consumed by the textile machine. At this time, the energy storage module needs to store energy; conversely, when the total weft insertion current curve is higher than the rated output current curve of the power grid, the electric energy output by the power grid is less than the electric energy consumed by the textile machine. At this time, the energy storage module needs to discharge to support the consumption of the textile machine.

[0070] As an optional embodiment, it further includes: a first connector, a second connector, a first rubber pad, a second rubber pad, a third rubber pad and a fourth rubber pad;

[0071] The first pin of the first connector passes through the first rubber pad to connect with the main control board 3, and the first pin passes through the second rubber pad to connect with the inverter 4;

[0072] The second pin of the second connector passes through the third rubber pad and is connected to the main control board 3 , and the second pin passes through the fourth rubber pad and is connected to the servo motor driver 5 .

[0073] In the present invention, it is considered that the textile factory needs to control the air humidity, and the textile machine will not be turned on during the Chinese New Year, which will produce water vapor condensation. Once it is turned off for a long time, it will cause the machine to explode. Therefore, this solution additionally sets up a first connector, a second connector, a first rubber pad, a second rubber pad, a third rubber pad and a fourth rubber pad, wherein the two connectors are respectively connected to the main control board 3 through corresponding pins and rubber pads, and are respectively connected to the inverter 4 and the servo motor driver 5 through corresponding pins and rubber pads. Compared with the existing electric control cabinets connected to each other by cables, the connection method of this solution does not need to connect each control device by cables, which not only reduces the volume inside the electric control cabinet, but also improves the waterproofness, thereby improving the safety and practicality of the solution.

[0074] As an optional embodiment, it also includes:

[0075] A photovoltaic panel disposed on the surface of the cabinet 1;

[0076] Photovoltaic energy storage module, used to store photovoltaic electricity generated by photovoltaic panels;

[0077] When the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid, the electric energy storage module 2 is controlled to discharge to the textile machine accordingly, including:

[0078] When the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid, the photovoltaic energy storage module is preferentially controlled to discharge to the textile machine, and when the power consumption of the textile machine at the current moment is greater than the sum of the rated output power of the power grid and the output power of the photovoltaic energy storage module, the electric energy storage module 2 is controlled to discharge accordingly to the textile machine.

[0079] In the present invention, considering that when the power consumption of the textile machine is greater than the rated output power of the power grid, the power control unit 6 needs to control the electric energy storage module 2 to discharge to the textile machine, but if the electric energy stored in the electric energy storage module 2 cannot fully meet the electric energy required for the actual work of the textile machine, it will also cause fluctuations in the power grid. Therefore, in order to meet the power consumption required for the actual work of the textile machine, this scheme also sets up additional photovoltaic panels and photovoltaic energy storage modules, wherein the photovoltaic panels are used for photovoltaic power generation, and the photovoltaic energy storage module will store the photovoltaic power generated by the photovoltaic panels, and discharge accordingly based on the control of the power control unit 6. In addition, in order to make full use of this part of clean energy-photovoltaic power, when the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid, the photovoltaic energy storage module is preferentially controlled to discharge to the textile machine, and when the power output of the photovoltaic energy storage module cannot meet the extra power consumption of the textile machine, the electric energy storage module 2 is controlled to discharge accordingly to the textile machine. This scheme not only introduces clean energy power generation-solar power generation, ensures environmental protection, but also meets the power consumption required for the actual work of the textile machine, and improves the reliability of the scheme.

[0080] It should be noted that this application adds photovoltaic energy storage, and the photovoltaic energy storage part can be selected. Depending on the location of the textile factory, it can be considered that the energy storage part is charged only with valley electricity. Photovoltaic panels can also be installed, and the power production capacity of the photovoltaic panels is initially processed in the power center before entering the energy storage.

[0081] It should also be noted that the electric control mode proposed in this scheme is: an integrated electric control cabinet of main control board 3 + servo motor driver 5 + inverter 4 + electric energy storage module 2 + photovoltaic energy storage. Advantages: Control of power consumption by means of photovoltaic energy storage. Expected use scenario 1: Due to the existence of peak and valley electricity in the power grid, charging and energy storage are carried out during the valley electricity period; when entering the peak electricity period, the electric energy storage module 2 discharges and works. Benefits: Reduce the operating load of the power grid; reduce the power cost pressure of the factory. Expected use scenario 2: Air-jet looms are currently deployed on a large scale in some areas. If the area is close to the cotton producing area and has the advantage of photovoltaic power generation, then scenario 2 can add the process of photovoltaic charging and energy storage on the basis of scenario 1. Because photovoltaic power cannot be directly used for equipment driving, it is pre-charged in the energy storage box. Reduce energy consumption. The main advantages of the present invention: reduce the power load of the power grid, reduce the production cost of the factory, and use photovoltaic power generation to introduce clean energy.

[0082] It should also be noted that, in practical applications, a textile system should include a textile machine and a textile drive control energy storage integrated cabinet as described above, and the textile drive control energy storage integrated cabinet is connected to the power grid and the textile machine respectively. In addition, the textile machine is generally provided with: a heald frame, a first servo motor, a second servo motor, a spindle motor, a plurality of solenoid valves, and a weft storage device; Figure 3As shown, the first servo motor can transport the warp to the heald frame based on the control of the servo motor driver 5 in the textile drive and energy storage integrated cabinet, and the heald frame will thread the received warp, and the weft storage device will spray out the weft based on the control of the main control board 3, and the sprayed weft will be transmitted to the heald frame through the drive of the solenoid valve, and the spindle motor will drive the heald frame to move up and down based on the control of the main control board 3 in the textile drive and energy storage integrated cabinet, and press the warp and weft after receiving the weft to generate textile cloth, and the generated textile cloth will be rolled up based on the control of the second servo motor to accurately complete the entire textile work.

[0083] It should also be noted that the textile machine can be regarded as a robot. The main control board 3 is the human brain, responsible for transmitting control instructions and controlling the actions of several major transmission units (servo motors, spindle motors). The sensing units (spindle encoders, tension sensors, weft feelers) are used to help the main control board 3 identify the current status of the machine so that the transmission units can perform appropriate acceleration and deceleration.

[0084] It should also be noted that in actual applications, the textile system can also add human-computer interaction (HMI), such as a touch screen. Workers connect to the main control board 3 through the touch screen to perform visual operations, which facilitates on-site adjustments of the machine. HMI inputs parameters according to the on-site situation. The main control board 3, as a central control element, automatically adjusts all functions of the machine after receiving the parameters of the HMI. The inverter 4 is the main motor drive, similar to a person's legs, responsible for the overall operation of the textile machine. Servo drive. It is mainly adjusted according to the value of the tension sensor, similar to a person's hands balancing while running. The role of the textile machine is to feed the warp into the machine and pull the woven cloth out of the machine for use.

[0085] It should also be noted that the energy storage function proposed in the present invention is a new function compared to the current products, and there is no similar function on the market. The models on the market can be defined as a textile drive integrated cabinet. The present invention adds an energy storage function on the basis of the drive. The energy storage function can save more electricity costs in power consumption control and reduce the load on the power grid. And in the case of a short-term accidental power outage of the power grid, it can ensure the normal operation of the equipment for a certain period of time. Ensure efficiency. It is impossible to guarantee the energy storage effect for a long time. Limited by the energy storage capacity limit. The equipment in the textile factory works 24 hours a day and 360 days a year, and only rests during the Chinese New Year. The energy storage device can effectively resist the instability of the equipment caused by power grid fluctuations or short-term power outages. It can ensure that the quality of the cloth is not affected. The energy storage module cannot be simply superimposed 1+1 with the existing market products. A combined design is required. At present, only Huichuan can make a similar design. The present invention will subsequently explain the drive and main control parts, greatly compress the size, make a more compact design, and add energy storage modules while ensuring that the heat dissipation and cabinet size remain unchanged. The larger the compressed space, the more electric energy the energy storage module can store. In addition, the present invention is very compact and can meet the IP65 waterproof standard, which can provide strict protection for the drive module and effectively reduce external influences to reduce the failure rate.

[0086] It should also be noted that in actual applications, considering that the power control unit 6 needs to control the energy storage or discharge of the electric energy storage unit according to the operating angle of the spindle motor during the actual operation of the textile machine, the present solution will also set up an additional spindle encoder on the basis of the original structure of the textile machine, so as to record the operating angle of the spindle motor during operation through the spindle encoder, which is convenient for the actual control of the power control unit 6. In addition, considering that whether the textile cloth can be normally generated is related to the length of the weft, the present solution will also set up an additional weft feeler on the basis of the original structure of the textile machine, and use it to collect the output length of the weft, thereby improving the accuracy of the textile process. Considering that the textile cloth needs to meet certain tension requirements, the present solution will also set up an additional tension sensor on the basis of the original structure of the textile machine, and collect the tension value of the textile cloth through the tension sensor, which is convenient for the main control board 3 to actually control the spindle motor, so as to ensure that the generated textile cloth meets the actual user needs.

[0087] It should also be noted that the specific structure of the drive control module in the textile drive control energy storage integrated cabinet provided in this application is as follows: Figure 4As shown, the main control board 3 + inverter 4 + servo motor driver 5, the arrangement of these modules occupies 80% of the area of ​​the entire electric control cabinet. The smallest design size on the market is 540*295*880 (length, width and height), including the power supply. The size of this design (excluding the power supply, the size of the power supply part and the energy storage size are calculated together) is only 430*192*300. This module has a two-layer structure. The upper layer is the main control board 3 with a protection level of IP54. The lower layer is the driver board with a protection level of IP65. Figure 5 After removing the upper main control board 3 structure, the remaining lower structure area, wherein the lower structure includes the inverter 4 + servo motor driver 5. Figure 5 The structure on the left is a 3-axis servo motor driver 5 , and the servo motor drivers 5 currently on the market are usually 2-axis. Figure 5 The right side is the inverter 4. The middle groove is a capacitor device. The inverter 4 and the servo motor driver 5 share the same group of capacitors to reduce the overall volume and improve utilization. The main control board 3 is equivalent to covering the entire lower driver, isolated by structural parts, and also meets the waterproof design. The connection between them is realized through waterproof pins. The above structure belongs to the center part of the top-level drive control module (main control board 3), the middle-level module is the power processing unit (power control unit 6), and the bottom layer includes the electric energy storage module 2 and the photovoltaic energy storage module, such as Figure 6 shown.

[0088] Please refer to Figure 7 , Figure 7 A process flow chart of a textile drive control energy storage control method provided by the present invention. The textile drive control energy storage control method is applied to the power control unit 6 in the textile drive control energy storage integrated cabinet as described above, comprising:

[0089] S11: Determine the current power consumption of the textile machine;

[0090] S12: When the power consumption of the textile machine at the current moment is less than the rated output power of the power grid, the electric energy storage module 2 is controlled to store the AC power transmitted by the power grid accordingly; when the power consumption of the textile machine at the current moment is greater than the rated output power of the power grid, the electric energy storage module 2 is controlled to discharge to the textile machine accordingly.

[0091] The textile drive and energy storage control method provided in this embodiment corresponds to the above-mentioned textile drive and energy storage integrated cabinet, so it has the same beneficial effects as the above-mentioned textile drive and energy storage integrated cabinet. Therefore, for the embodiments of the textile drive and energy storage control method, please refer to the description of the embodiments of the textile drive and energy storage integrated cabinet, which will not be repeated here.

[0092] As an optional embodiment, it also includes:

[0093] Determine whether the textile machine is operating in a steady state at the current moment;

[0094] If the textile machine is operating in a steady state at the current moment, when the load power consumption and the sum of the power consumption corresponding to the load energy consumption data of the textile machine at the current moment are greater than the rated output power of the power grid, the electric energy storage module 2 is controlled to discharge to the textile machine accordingly.

[0095] In the present invention, considering that the load energy consumption data of the textile machine when it is in a steady state (mainly due to the different losses between equipment caused by mechanical differences) will affect the power consumption of the textile machine, this scheme also needs to determine whether the textile machine is operating in a steady state at the current moment. If the textile machine is operating in a steady state at the current moment, it is necessary to make the load power consumption corresponding to the load energy consumption data of the textile machine at the current moment and the sum of the power consumption greater than the rated output power of the power grid, that is, if the textile machine has load energy consumption, the electric energy storage module 2 is required to supply power to the textile machine to balance the load power consumption corresponding to the load energy consumption data. There is no need for the power grid to transmit this part of the load power, which greatly reduces the impact on the power grid and reduces the operating load of the power grid.

[0096] It should be noted that in actual applications, after a period of time, assuming that the textile machine is in steady-state operation at 700 revolutions, the electric energy storage module 2 collects the energy consumption data of the periodic load (mainly due to the different losses between the equipment caused by mechanical differences) to draw a load curve, and infers the load peak time point that appears according to the angle. With the loss of the machinery, data collection is performed once a month. The load increase or decrease caused by the mechanical loss of the textile machine equipment is analyzed. According to the acquired load curve, the energy storage power is released in advance at the predicted load peak to ensure stable power supply at high loads. For example, when the textile machine is about to reach a high speed, the system can release a certain amount of energy storage in advance to cope with the upcoming peak load. Assuming that the power that the normal power supply network can provide is 400W, the peak load will reach an instantaneous 600W as the speed of the textile machine increases, which will cause the fluctuation of the grid voltage, thereby affecting the stable state of the textile machine equipment at high speed. In the present invention, the electric energy storage module 2 provides additional overload power when the load power consumption and rated power consumption of the textile machine are greater than the power supply power of the grid. To stabilize the working voltage of textile machinery equipment and improve the stability of textile machinery at high speed.

[0097] As an optional embodiment, it also includes:

[0098] Collect the arrival time of the weft line of the textile machine to the weft detection monitoring point;

[0099] Determine whether the arrival time is less than a preset arrival time threshold;

[0100] If the arrival time is less than the preset arrival time threshold, it is determined that the weft thread arrives at the weft detection monitoring point in advance, and the opening time of the solenoid valve in the textile machine is reduced, triggering the step of collecting the arrival time of the weft thread in the textile machine arriving at the weft detection point until the arrival time is not less than the preset arrival time threshold.

[0101] In the present invention, because the weft insertion action of the textile machine is related to the arrival angle of the weft thread, if the weft thread arrives in advance, it means that the opening time of the solenoid valve in the textile machine is too long. Therefore, this scheme first collects the arrival time of the weft thread in the textile machine to the weft detection monitoring point, and then determines whether the arrival time is less than the preset arrival time threshold. If the arrival time is less than the preset arrival time threshold, it is determined that the weft thread arrives at the position in advance, and the opening time of the solenoid valve in the textile machine is reduced. By reducing the opening time of the solenoid valve, the purpose of closing the arrival angles of several weft threads in advance is achieved, thereby saving the power consumption of the textile machine and reducing energy loss.

[0102] It should be noted that the weft detector in the textile machine can detect the arrival time of the weft thread. When it is detected that the weft thread arrives ahead of time, the opening time of the solenoid valve can be reduced to reduce the energy consumption of the textile machine and minimize the power loss in each cycle.

[0103] As an optional embodiment, after controlling the electric energy storage module 2 to discharge the textile machine accordingly, the method further includes:

[0104] Determine whether the energy lost by the electric energy storage module 2 after discharge is fully replenished within a preset time;

[0105] If the energy lost by the electric energy storage module 2 after discharge is not fully replenished within a preset time, a corresponding alarm is issued.

[0106] In the present invention, because the function of the electric energy storage module 2 is to balance the power consumption of the textile machine, the load power consumption of the textile machine and the rated output power of the power grid, it is necessary to ensure that the electric energy storage module 2 is in a state of sufficient energy within a certain period of time after power output to cope with the next power balance. Therefore, after controlling the electric energy storage module 2 to discharge the textile machine accordingly, this scheme also makes a judgment on whether the energy lost by the electric energy storage module 2 after discharge is fully replenished within the preset time. If the energy lost by the electric energy storage module 2 after discharge is not fully replenished within the preset time, it proves that the electric energy storage module 2 may not be able to meet the power required for the next power balance, so it is necessary to immediately issue an alarm to remind the user of the current status of the electric energy storage module 2, thereby improving the stability and reliability of the scheme.

[0107] It should be noted that in actual applications, it is necessary to calculate the energy release and charging of the electric energy storage module 2 in each cycle. The calculation method is: according to the load curve mentioned above, calculate the energy lost by overload in one cycle, assuming 5 joules of energy. Then in the time period of energy supply>load, 5 joules of energy should be supplemented. In this way, it can be ensured that in each cycle, the structure of the electric energy storage module 2 will not lose the overall energy storage to deal with other unexpected events, that is, to ensure that the energy of the electric energy storage module 2 is fully supplemented in each cycle without energy loss.

[0108] It should also be noted that the cycle charge and discharge description: Assume that the electric energy storage module 2 can store 50 joules of energy. The overload peak of each cycle, assuming that the overload corresponding angle is 200-300 degrees, will consume 5 joules of energy. Then in the 0-200 degree and 300-360 degree cycles, 5 joules of energy should be supplemented to maintain the high-speed operation of the textile machine and the cycle power balance.

[0109] Responding to power supply network fluctuations: The difference is that the periodic discharge is to make the textile machine run more stably and faster under stable conditions. Responding to the power supply network is to keep the textile machine working smoothly. When the energy storage module 2 cannot be fully charged, the charging = releasing scheme of each cycle will not be maintained.

[0110] It should also be noted that, for example, the current speed of the textile machine is 700 rpm, and the power supply network normally maintains a power of 400W, but due to external factors, the power drops to 200W for a short time. Because the power supply is too low, in order to ensure the normal operation of the textile machine, the energy released by the electric energy storage module 2 must be greater than the supplemented energy. Therefore, the stored energy will gradually decrease. If the power supply is unstable for a long time, when the stored energy becomes 0, the textile machine can only be in a shutdown state at this moment. But suppose there is a 10-minute power supply fluctuation in 1 hour. The electric energy storage module 2 can effectively cover the voltage fluctuation time period. And charge it in the subsequent time. That is, it is judged whether the energy of the electric energy storage module 2 can be fully charged after each cycle. If it can be fully charged, it proves that the external power supply is stable, and the textile machine can be supported at high speed at this time. The cycle charging of the energy of the electric energy storage module 2 = cycle release; on the contrary, if it cannot be fully charged, it proves that when the external power supply is unstable, the textile machine does not support high-speed operation, and a stable operation mode is required. The energy stored in the electric energy storage module 2 is used for supplementation, and the cycle charging> cycle release.

[0111] As an optional embodiment, it also includes:

[0112] Collect the current rotation speed of the textile machine and the current rotation speed of other textile machines;

[0113] Determine whether the current rotation speed of the textile machine is equal to the current rotation speed of other textile machines;

[0114] If the current rotational speed of the textile machine is equal to the current rotational speeds of other textile machines, the rotational speeds of other textile machines are adjusted according to a preset rotational speed relationship until the rotational speed of the textile machine and the rotational speeds of other textile machines satisfy the preset rotational speed relationship.

[0115] In the present invention, considering that there are multiple textile machines in a textile, and in order to centrally manage multiple textile machines, the self-organizing network technology can be used to integrate multiple textile machines and centrally collect the parameters of the corresponding textile machines. However, when multiple textile machines are at the same speed, the textile machines are prone to resonance, resulting in obvious shaking of the textile machines, increased vibration, and the corresponding load will also increase accordingly. Therefore, this scheme collects the current speed of each textile machine, and adjusts the speed of other textile machines according to the preset speed relationship when the speeds of each textile machine are equal. The purpose is to control the speed of each textile machine to be unequal and meet the preset speed relationship, so as to stagger the vibration amplitude of each textile machine, thereby improving the safety of the scheme. For example: when 5 textile machines are at the same speed, the textile machines are prone to mechanical shaking due to resonance, increased vibration, and the load will also increase accordingly. Based on 1500 revolutions, the speeds of each textile machine can be adjusted to 1490, 1480, 1500, 1480, and 1490 respectively to stagger the vibration amplitude of each textile machine.

[0116] As an optional embodiment, it also includes:

[0117] Determine the first moment corresponding to when the load energy consumption data of the textile machine within a preset period is equal to a preset energy consumption peak value;

[0118] Determine a second moment corresponding to when the load energy consumption data of other textile machines within a preset period is equal to a preset energy consumption peak value;

[0119] Determine whether the first moment is equal to the second moment;

[0120] If the first moment is equal to the second moment, the loads of other textile machines are adjusted until the first moment is not equal to the second moment.

[0121] In the present invention, considering that if the time when the load energy consumption data of each textile machine reaches the peak value is the same, it will greatly increase the demand for the power supply network and will also interfere with the voltage fluctuation of the power grid. Therefore, this scheme respectively determines the first moment corresponding to the time when the load energy consumption data of the textile machine within the preset period is equal to the preset energy consumption peak value and the second moment corresponding to the time when the load energy consumption data of other textile machines within the preset period is equal to the preset energy consumption peak value, and then determines whether the first moment is equal to the second moment. If the first moment is equal to the second moment, it is necessary to adjust the load of other textile machines until the first moment is not equal to the second moment. By adjusting the load of other textile machines to stagger the time when the load energy consumption data of each textile machine reaches the peak value, the demand for the power supply network is greatly reduced, and the voltage fluctuation of the power grid can also be stabilized.

[0122] It should be noted that the Internet of Things technology can be used to turn each textile machine into a node. Assuming that there are 10 textile machines with an operating cycle of 1 second, all of them currently reach their energy consumption peak in 0.5-0.6 seconds. Then, each textile machine can be operated at a staggered peak, with the peak time of the first machine advanced to 0-0.1 seconds, the second to 0.1-0.2 seconds, and the third to 0.2-0.3 seconds. By analogy, the energy consumption peaks of the 10 textile machines are all staggered, which can further reduce the requirements for the power supply network and stabilize voltage fluctuations.

[0123] It should also be noted that if Figure 8As shown, the working principle of the entire textile machine can be divided into the following processes: 1. The worker adjusts the machine (mechanical adaptation) for the initial operation of the equipment; 2. Normal operation at 1200 rpm (assuming that the original power state can only support 1200 rpm). The normal operation of the textile machine requires power from the external power grid, and the external power grid will also charge the electric energy storage module 2. When the electric energy storage module 2 is fully charged and the textile machine is operating normally at 1200 rpm, the electric energy storage module 2 will supply power to the textile machine and periodically collect the load energy consumption data of the textile machine; 3. Through machine self-adjustment: different textile machines have different mechanical loads, and the load curve is drawn according to their corresponding load energy consumption data (different textile machines will be retired over time, and the deformation of parts will occur. The change in load state will cause the power loss to be different from the factory value. The machine self-adjustment can self-check the state of the textile machine and provide data to support the release algorithm); 4. Release algorithm based on load prediction (release algorithm description: according to the predicted load energy consumption peak, the release algorithm is provided Release the stored energy in advance to ensure stable power supply under high load. For example, when the textile machine is about to reach a high speed, the system can release a certain amount of stored energy in advance to cope with the upcoming peak load); 5. Encoder data sampling: sampling the real-time operation fluctuations of the textile machine; 6. Load peak prediction: the encoder angle is used as the time axis to predict the load peak; 7. Weft detection data sampling: detect the angle of arrival of the weft; 8. Weft insertion module sub-adjustment: without affecting the work efficiency, close the electric valve in advance to reduce energy consumption; 9. Feedback control system: the electric energy storage module samples energy consumption data; 10. Dynamic adjustment algorithm: assuming that the current speed is 1200, the periodic energy release and charging balance point of the electric energy storage module 2 is obtained according to the current operation data of the textile machine, and the limit speed that the textile machine can continue to rise is inferred, and high-speed load prediction is performed to unlock higher speed options. Assume that when the speed is raised to 1500, the electric energy storage module 2 can increase the release amount in advance according to the time of the feedback control system to stabilize the power supply at a higher speed; 11. Internet of Things technology: Make the textile machine enter the self-organizing network mode and quickly realize the dynamic networking on site. The above is a description of the adaptive work of the electric energy storage module 2 of a single textile machine. Through the Internet of Things technology, after the self-organizing network between textile machines is carried out, linkage control is carried out. For multiple textile machines, through the self-organizing network technology, after the data of the adjacent textile machines are collected from each other, one of the textile machines is used as the processing center to perform data analysis, and the operating speed and start time of each textile machine are adjusted through the dynamic adjustment algorithm between the textile machines, the load energy consumption peaks appear, and the vibration amplitude is suppressed.

[0124] It should also be noted that, taking the example of 20 textile machines self-organizing network: each textile machine automatically forms a small network to perform self-control within the range. For example, a network is formed between textile machines 1-10, and the fluctuations of the machine data are suppressed and adjusted. A network is also formed between textile machines 6-15, and the peak shifting control is adjusted with each other.
