[0051] The jig status monitoring unit 13 is used to monitor the switching state between several jigs.

[0052] In this embodiment, the personnel detection unit 11 uses devices such as infrared sensors or cameras, which are installed in the working area of the processing equipment to monitor in real time whether the operator is on duty. When the operator leaves the working area for more than a certain period of time, the personnel detection unit 11 can detect it in time and send a signal to the frequency converter control module 2. The device status monitoring unit 12 monitors whether the device is in a processing state by installing pressure sensors, current sensors, etc. on the device. The pressure sensor can detect the pressure exerted by the device on the product, and the current sensor can monitor the operating current of the motor, so as to determine whether the device is actually performing processing work. The jig status monitoring unit 13 installs position sensors on the automatic machine to monitor the switching state between several jigs.

[0056] The frequency converter drive unit 23 is used to convert the adjustment plan into specific frequency converter control signals and drive the frequency converter to adjust the output frequency.

[0057] In this embodiment, the signal receiving and parsing unit 21 is responsible for receiving signals from the device operation status monitoring module 1 and parsing and processing them. These signals include information such as whether the operator is on duty, whether the device is in the processing state, and whether the fixture is in the switching state. The control strategy formulation unit 22 formulates a corresponding motor speed adjustment plan according to the parsed signals in combination with the preset energy-saving control strategy. When the operator is away from the post for more than a certain period of time, the control strategy formulation unit 22 issues an instruction to reduce the motor speed or suspend the motor operation; when the device is in a non-processing state, the motor speed is adjusted to the energy-saving mode; when the fixture is switched, the motor speed is reasonably controlled to reduce energy waste. The frequency converter drive unit 23 converts the control instructions generated by the control strategy formulation unit 22 into specific frequency converter control signals, drives the frequency converter to adjust the output frequency, thereby controlling the speed of the motor, and realizing energy-saving operation of the device in different working states.

[0058] Further, the data storage and analysis module 3 includes a data storage unit 31 and a data analysis unit 32, and the data storage unit 31 is connected to the data analysis unit 32;

[0059] The data storage unit 31 is used to store the original data collected by the device operation status monitoring module 1;

[0060] The data analysis unit 32 deeply analyzes the stored data to discover the laws of device operation and the characteristics of energy consumption.

[0061] In this embodiment, the data storage unit 31 stores the original data collected by the device operation status monitoring module 1, including the operator's on-duty situation, the device processing state, the fixture switching state, etc., as well as the operation records of the frequency converter control module 2, such as motor speed changes and control strategy execution situations. These data will be classified and stored for subsequent query and analysis. The data analysis unit 32 deeply analyzes the stored data to discover the laws of device operation and the characteristics of energy consumption. By analyzing the relationship between the operator's off-duty time and the motor's idling time, the response time of the personnel detection unit 11 is further optimized; by analyzing the energy consumption of the device in different processing states, the frequency converter control strategy is adjusted to achieve more precise energy-saving control.

[0062] Further, the human-machine interface 4 module includes a status display unit 41, a parameter setting unit 42, a data analysis display unit 43, and an alarm prompt unit 44;

[0063] The status display unit 41 is used to display the operation status of the processing device in real time;

[0066] The alarm and prompt unit 44, when the system detects an abnormal situation, reminds the operator to handle it through means such as sound and light alarms.

[0067] In this embodiment, the status display unit 41 visually displays the operating status of the processing equipment in the form of graphics or text in real time, including whether the operator is on duty, whether the equipment is in the processing state, whether the fixture is in the switching state, etc. At the same time, it displays information such as the current speed of the motor and the output frequency of the frequency converter, enabling the operator to clearly understand the operating conditions of the equipment. The parameter setting unit 42 provides a friendly operation interface, facilitating the operator to set system parameters according to actual production requirements, such as the threshold for the operator's off-duty time, the adjustment range of the motor speed, the minimum speed in the energy-saving mode, etc. These parameter settings will directly affect the energy-saving effect of the system and the operating performance of the equipment. The data analysis and display unit 43 visually presents the analysis results in the data storage and analysis module to the operator in the form of charts, reports, etc., showing the energy consumption change trend and energy-saving effect comparison of the equipment in different time periods, helping the operator better understand the operating rules and energy-saving potential of the equipment, and providing data support for production management decisions. The alarm and prompt unit 44, when the system detects an abnormal situation, such as motor overload, sensor failure, etc., promptly reminds the operator to handle it through means such as sound and light alarms. At the same time, the detailed content of the alarm information, including the alarm time, alarm type, possible reasons, etc., is displayed on the human-machine interface 4, so that the operator can quickly locate and solve the problem.

[0068] Please refer to Figure 6 , second aspect, an energy-saving control method for a processing equipment based on a frequency converter, which is used for the energy-saving control system of the processing equipment based on a frequency converter described in the first aspect, includes the following steps:

[0069] S1: Obtain the working status information of the processing equipment in real time;

[0070] Specifically, through personnel detection devices such as infrared sensors or cameras installed in the working area of the equipment, it is monitored in real time whether the operator is on duty. When the operator enters or leaves the working area, the personnel detection unit 11 can quickly capture this change and transmit the relevant information to the frequency converter control module 2. If the infrared sensor detects no infrared signal of human activity in the working area for a long time, it is determined that the operator is off duty; conversely, if a human activity signal is detected, it is determined that the operator is on duty. Equipment status monitoring devices such as pressure sensors and current sensors are installed at key parts of the equipment to monitor in real time whether the equipment is in the processing state. The pressure sensor can detect the pressure exerted by the equipment on the product. When the pressure reaches a certain threshold, it is determined that the equipment is in the processing state; the current sensor monitors the operating current of the motor. When the current reaches the normal range during processing, it is also determined that the equipment is in the processing state. These monitoring data will be sent to the frequency converter control module 2 in a timely manner to provide a basis for formulating subsequent control strategies. Position sensors or proximity switches and other fixture status monitoring devices are installed on the automatic machine to monitor the switching state between several fixtures. When the fixture is in the switching process, the position sensor or proximity switch can detect the position change of the fixture in time and transmit this status information to the frequency converter control module 2 to reasonably control the motor speed and reduce energy waste.

[0071] S2 Formulate corresponding frequency converter control strategies according to the monitored equipment operating status information;

[0072] Specifically, when the frequency converter control module 2 receives the operator off-duty signal transmitted by the personnel detection unit 11 and the off-duty time exceeds the preset threshold (5 minutes), the control strategy formulation unit 22 will issue an instruction to reduce the motor speed to the preset low-speed state (30% of the rated speed) or suspend the motor operation. This strategy aims to avoid the high-speed idling of the motor during the operator's off-duty period and effectively reduce power energy waste. According to the data transmitted by the equipment status monitoring unit 12, when the equipment is in the non-processing state, such as when the equipment pauses processing waiting for product assembly, equipment fault repair, etc., the control strategy formulation unit 22 will adjust the motor speed to the energy-saving mode. The motor speed in the energy-saving mode will be reasonably set according to the actual situation of the equipment and subsequent processing requirements, which can not only ensure that the equipment can quickly resume processing at any time, but also minimize energy consumption. When receiving the fixture switching signal transmitted by the fixture status monitoring unit 13, the control strategy formulation unit 22 will reasonably control the motor speed according to the time and sequence requirements of the fixture switching. During the fixture switching process, the motor may run at a lower speed to reduce energy consumption during the switching process; and when the fixture switching is completed, the motor will quickly resume to the corresponding processing speed according to the actual processing requirements to ensure the continuity and efficiency of production.

[0073] S3 Adjust the output frequency of the frequency converter in real time according to the formulated control strategy;

[0074] Specifically, the frequency converter drive unit 23 in the frequency converter control module 2 converts these instructions into specific frequency converter control signals according to the control instructions generated by the control strategy formulation unit 22. These control signals contain specific parameters for adjusting the motor speed, such as the target speed, acceleration time, deceleration time, etc. The frequency converter drive unit 23 transmits the control signals to the frequency converter in real time through the communication interface with the frequency converter (such as RS485 interface, Profibus-DP bus, etc.), ensuring that the frequency converter can accurately receive the instructions and perform corresponding actions. After receiving the control signals, the frequency converter adjusts its output frequency according to the parameters in the signals. When it is necessary to reduce the motor speed, the frequency converter gradually reduces the output frequency to smoothly decelerate the motor; when it is necessary to increase the motor speed, the frequency converter gradually increases the output frequency to smoothly accelerate the motor. During the entire adjustment process, the frequency converter will monitor parameters such as the running current and voltage of the motor in real time to ensure that the motor operates in a safe and stable state and avoid faults such as motor overload and overvoltage caused by sudden speed changes. By installing a speed feedback device such as an encoder on the motor, the actual speed of the motor is monitored in real time, and the speed information is fed back to the frequency converter control module 2. The frequency converter control module 2 compares the feedback speed information with the target speed. If there is a deviation, it will promptly adjust the output frequency of the frequency converter to form a closed-loop control system. This closed-loop control method can effectively improve the control accuracy of the motor speed, ensure that the motor always operates at the preset speed, and further improve the energy-saving effect and the operating stability of the equipment.

[0075] S4 stores the data collected by the equipment operation status monitoring module 1 and the operation records of the frequency converter control module 2 in the data storage and analysis module 3;

[0076] Specifically, the data storage unit 31 is responsible for receiving and storing the raw data collected by the device operation status monitoring module 1, including information such as the presence of operators, the processing status of the device, and the fixture switching status, as well as the operation records of the frequency converter control module 2, such as data on the motor speed change curve and the execution time of the control strategy. These data will be sorted and organized according to different dimensions such as time sequence, device number, and process type during storage for subsequent query and analysis. The operation data of different devices within the same time period can be stored in the same folder and sorted by date and time, facilitating operators and data analysts to quickly locate the required data. The data analysis unit 32 conducts in-depth analysis on the stored data to explore the operation rules of the device and the characteristics of energy consumption. By comparing the device operation data in different time periods and under different production tasks, the actual effect of the energy-saving control strategy can be evaluated. The relationship between the operator's off-duty time and the motor idling time can be analyzed to further optimize the response time of the personnel detection unit 11; or the energy consumption of the device in different processing states can be analyzed to adjust the speed adjustment range and energy-saving mode parameters in the frequency converter control strategy to achieve more precise energy-saving control. In addition, through statistical analysis methods, the energy consumption difference of the device before and after adopting the energy-saving control system can be calculated to visually display the energy-saving effect, providing strong data support for the enterprise's energy conservation and emission reduction decisions.

[0077] The operator views the device operation status and energy-saving effect through the human-machine interface 4 and adjusts and optimizes the system parameters according to the actual situation.

[0078] Specifically, the operator can view the operating status and energy-saving effect of the equipment in real time through the human-machine interface 4 module. The status display unit 41 displays information such as whether the operator is on duty, whether the equipment is in the processing state, and whether the fixture is in the switching state in an intuitive graphical or text form. At the same time, key parameters such as the current speed of the motor and the output frequency of the frequency converter are displayed, enabling the operator to clearly understand the operating conditions of the equipment. The data analysis and display unit 43 visually presents the analysis results in the data storage and analysis module to the operator in the form of charts, reports, etc., such as the energy consumption change trend of the equipment in different time periods, the comparison of energy-saving effects, etc., to help the operator better understand the operating rules and energy-saving potential of the equipment. Based on this information, the operator can adjust and optimize the system parameters through the parameter setting unit 42, such as modifying the threshold of the operator's off-duty time, adjusting the amplitude of the motor speed adjustment, setting the speed of the new energy-saving mode, etc. These parameter adjustment information will be sent to the frequency converter control module 2 for updating the control strategy to further improve the energy-saving effect and adaptability of the system. At the same time, when the system detects an abnormal situation, the alarm prompt unit 44 promptly reminds the operator to handle it through sound and light alarms, etc., and displays the detailed content of the alarm information on the human-machine interface 4, including the alarm time, alarm type, possible reasons, etc., so that the operator can quickly locate and solve the problem.
