The above-mentioned scheme solves the technical problem that in the prior art, a press machine will generate relatively large noise during actual operation, and the noise not only affects the physical and mental health of the operators, but also easily interferes with the normal operation of surrounding equipment and even causes safety hazards.

[0041] According to this specific implementation, the model building module 104 uses historical data and characteristic parameters as a training set, obtains parameters of a noise prediction model through training, and builds a control model according to the noise prediction model and the control target;

[0047] According to the received control instructions and noise reduction strategies, the operating parameters of the press, such as pressure, speed, and frequency, are adjusted.

When used specifically, the noise and vibration conditions of the press during operation are first monitored in real time through the monitoring module 101, and transmitted to the characteristic analysis module 103 through the transmission module 102; then the characteristic analysis module 103 analyzes the received noise and vibration data to extract characteristic information information, and transmit the data to the noise reduction strategy designation module; then the noise reduction strategy formulation module 105 adopts the constructed control model and the extracted feature information to formulate a specific noise reduction strategy; then the GSM module 106 realizes the remote monitoring and communication functions, and sends the noise reduction strategy and control instructions generated by the noise reduction strategy formulation module 105 to the control module 107; finally, according to the received control instructions and noise reduction strategy, the pressure, speed, frequency and other operating parameters of the press are adjusted, and the adjusted noise and vibration levels are monitored in real time, and the control strategy is continuously optimized through the feedback mechanism. In this way, the technical problem that the press in the prior art will generate a lot of noise during actual operation, which not only affects the physical and mental health of the operators, but also easily interferes with the normal operation of surrounding equipment and even causes safety hazards is solved.

[0049] The present invention monitors the noise and vibration conditions of the press in real time during operation through the monitoring module 101, thereby ensuring the real-time and accuracy of the data. The noise reduction strategy formulation module 105 utilizes advanced machine learning algorithms and control models, combined with the extracted feature information, to intelligently formulate a specific noise reduction strategy. The formulated noise reduction strategy not only considers the noise reduction effect, but also takes into account the cost and technical feasibility, thereby ensuring the economy and practicality of the solution.

[0050] At the same time, by real-time monitoring of the adjusted noise and vibration levels and continuously optimizing the control strategy with the help of feedback mechanism, the continuity and stability of the noise reduction effect are ensured.

[0051] Secondly, the base 109 is arranged on the press, and the base 109 has a guide groove 118, a groove 119, a first through hole 120 and a second through hole 121. The force block 114 is connected to the control module 107, and the force block 114 is slidably connected to the guide groove 118. The force block 114 has a clamping groove 122, and the sliding member 110 is slidably connected to the groove 119.

[0056] When using a low noise control device for a press machine according to the present embodiment, the noise and vibration conditions of the press machine during operation are first monitored in real time by the monitoring module 101, and transmitted to the characteristic analysis module 103 by the transmission module 102; then the characteristic analysis module 103 analyzes the received noise and vibration data, extracts characteristic information, and transmits the data to the noise reduction strategy designation module; then the noise reduction strategy formulation module 105 formulates a specific noise reduction strategy using the constructed control model and the extracted characteristic information; then the GSM module 106 realizes the remote monitoring and communication functions, and sends the noise reduction strategy and control instructions generated by the noise reduction strategy formulation module 105 to the control module 107; finally, according to the received control instructions and noise reduction strategy, the operating parameters of the press machine such as pressure, speed, and frequency are adjusted, and the adjusted noise and vibration levels are monitored in real time, and the control strategy is continuously optimized through the feedback mechanism, so as to solve the technical problem that the press machine in the prior art will generate a large noise during actual operation, and the noise not only affects the physical and mental health of the operators, but also easily interferes with the normal operation of the surrounding equipment, and even causes safety hazards.

[0057] The present invention monitors the noise and vibration conditions of the press in real time during operation through the monitoring module 101, thereby ensuring the real-time and accuracy of the data. The noise reduction strategy formulation module 105 utilizes advanced machine learning algorithms and control models, combined with the extracted feature information, to intelligently formulate a specific noise reduction strategy. The formulated noise reduction strategy not only considers the noise reduction effect, but also takes into account the cost and technical feasibility, thereby ensuring the economy and practicality of the solution.

[0058] At the same time, by real-time monitoring of the adjusted noise and vibration levels and continuously optimizing the control strategy with the help of feedback mechanism, the continuity and stability of the noise reduction effect are ensured.

[0081] According to this specific implementation method, a noise reduction strategy combining active noise reduction and passive noise reduction is formulated in combination with the structural characteristics and operating parameters of the press.

7. The low noise control device for a press machine according to claim 6, characterized in that: The press low noise control device further comprises a monitoring module, and the monitoring module is connected to the control module.

8. A method for controlling low noise of a press machine, using the low noise control device of a press machine as claimed in claim 7, characterized in that: The steps include: First, the noise and vibration conditions of the press machine during operation are monitored in real time by the monitoring module, and transmitted to the characteristic analysis module by the transmission module; Then, the characteristic analysis module analyzes the received noise and vibration data, extracts characteristic information, and transmits the data to the noise reduction strategy designation module; Then, the noise reduction strategy formulation module formulates a specific noise reduction strategy using the constructed control model and the extracted feature information; Then the GSM module realizes the remote monitoring and communication functions, and sends the noise reduction strategy and control instructions generated by the noise reduction strategy formulation module to the control module; Finally, according to the received control instructions and noise reduction strategies, the operating parameters of the press, such as pressure, speed, and frequency, are adjusted. At the same time, the adjusted noise and vibration levels are monitored in real time, and the control strategy is continuously optimized through the feedback mechanism.
