Description

Technical Field

[0001] This invention relates to the field of mechanical rotating equipment installation foundation technology, and in particular to an active vibration damping and noise reduction base, an active vibration damping and noise reduction system based on the base, and a control method thereof. Background Technology

[0002] All rotating mechanical equipment experiences vibration during operation, especially high-power high-voltage asynchronous motors, hydro generators, and steam generators. The vibration is particularly noticeable during startup when the equipment passes through the resonance zone. Even after startup, normal operation generates significant vibration, causing severe noise pollution in the production environment and leading to loosening of fixing screws, vibration of building foundations and floors, and exacerbating resonance during normal operation.

[0003] Most rotating equipment on construction sites uses rigid bolt connections, which have poor vibration reduction effects. Power equipment that uses damping and vibration reduction buffer structures as connection foundations is mostly stationary power equipment. For example, when substations carry out noise control, they add damping and vibration reduction structures to the foundations of transformers, reactors, and instrument transformers to reduce vibration, which is a passive noise reduction. However, it is impossible to control the vibration according to the working conditions and vibration intensity, and actively destroy the resonance.

[0004] Patent application CN101382178A discloses an active vibration damping and isolation device and an active vibration damping and isolation system. The active vibration damping and isolation device includes: an air chamber with a sealed piston; an inverted pendulum, one end of which is fixedly connected to the piston; a load-bearing component, fixedly connected to the other end of the inverted pendulum; a vertical linear actuator disposed between the load-bearing component and the air chamber, and connected to the load-bearing component and the air chamber housing, to apply an active force to the load-bearing component; and a horizontal linear actuator disposed between the load-bearing component and the air chamber, and connected to the load-bearing component and the air chamber housing. The invention applies an active force to the load-bearing component. By adding an air-bearing structure between the stator and base of the linear actuator, bidirectional stiffness is provided through vacuum preloading or two opposing air-bearing forces. This allows the vertical linear actuator to move in the horizontal plane, while the horizontal linear actuator can move in the vertical plane. This eliminates the mutual constraint between the two actuators, increases the range of motion of the load, and improves the vibration reduction effect of the active damper. However, the invention is relatively complex, and the precision of the control system is not perfect, which affects the active vibration reduction effect. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, the present invention aims to provide an active vibration damping and noise reduction base, an active vibration damping and noise reduction system based on the base, and a control method. The vibration damping base is installed on the equipment foundation, and the electromagnetic brake on the vibration damping base is controlled by an edge controller to clamp the equipment shell, actively destroying resonance. At the same time, the edge controller has the ability to store sensor data locally and on the cloud platform, and to test and evaluate the stored data using different mathematical models to obtain the optimal active noise reduction control strategy, which is intelligent and efficient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The power input terminals of the electromagnetic brake 3, pressure sensor 2, and vibration swing sensor 1 are respectively connected to a power conversion device 15 and a power supply 16 in sequence through a voltage stabilizing module 14.

[0008] A current transformer is installed between the signal input terminal of the edge controller 13 and the power distribution input of the vibration isolation object to collect the current changes of the vibration isolation object.

[0009] The vibration damping positioning seat 12 includes a positioning partition 5, a vibration damping rubber plate 12 is provided at the bottom of the positioning partition 5, and positioning rubber plates 6 are provided on both sides of the vibration damping rubber plate 12. The positioning bolt 4 passes through the positioning partition 5 and the positioning rubber plate 6 to fix the vibration damping positioning seat 12 on the installation foundation of the equipment.

[0010] The legs of the limiting bracket 10 are suspended in the air.

[0011] The active vibration control system (AVCS) based on the above-mentioned base includes:

[0012] System self-test module: When the AVCS system is powered on, it performs hardware self-test and logic self-test on the edge controller 13;

[0013] Data identification module: used to preprocess the displacement and swing signals measured by the vibration swing sensor 1 and the pressure signal measured by the pressure sensor 2 on the active vibration damping and noise reduction base;

[0014] Lockout function module: used for manual / automatic control mode locking when the edge controller 13 stops in an emergency, and for the electromagnetic brake 3 on the active vibration damping and noise reduction base to be de-energized and released.

[0015] Control Anomaly Handling Module: Used to activate the interlock function when the automatic control fails to converge or when the AVCS system experiences a control anomaly.

[0016] Automatic control module: The edge controller 13 of the AVCS system automatically controls the electromagnetic brake 3 on the active vibration damping and noise reduction base to achieve active vibration reduction based on the data values ​​collected by the vibration swing sensor 1 and the pressure sensor 2.

[0017] Manual control module: used for jogging control of the electromagnetic brake 3 on the active vibration damping and noise reduction base, realizing human intervention in active vibration reduction and hardware testing;

[0018] Alarm module: It detects the real-time data collected by the AVCS system and issues an alarm signal when the detected data does not conform to the defined normal parameter state. At the same time, it automatically generates an alarm display according to the control command.

[0019] Historical data recording module: used to record the test process and test results into the tuning log;

[0020] Operation monitoring module: used for locking and commissioning of vibration isolation objects, generating and modifying real-time database parameters, generating and modifying reports and screens, selecting local and remote control of vibration isolation objects, and monitoring the AVCS system operation status diagram.

[0021] Access control module: Supports custom users and operation permissions, can prevent unauthorized operations, and all manual operations are logged.

[0022] The control method based on the above active vibration reduction and noise reduction system includes the following specific steps:

[0023] S1 Data Identification

[0024] When the AVCS system is powered on, the system self-test module first performs hardware self-test and logic self-test of the edge controller 13; then, the AVCS system preprocesses the displacement, swing and pressure signals through the data identification module: the system caches n measurement results, filters abnormal data points by an abnormal data removal filtering algorithm on the n sampled values, and smooths the data through a data smoothing algorithm;

[0025] S2 System Lockout and Control Anomaly Judgment

[0026] Users can customize the four operating conditions and parameter values ​​of the AVCS system—run, exit, lockout, and control anomaly—through the permission management module.

[0027] The running and exit statuses are manually enabled or disabled via the manual control module.

[0028] When sensor data is interrupted, fault lockout signal is received, data value and quality are abnormal, frequency is abnormal, or manually defined lockout data point is abnormal, the alarm module will display the alarm and the system lockout function module will enter the lockout state. Once the data returns to normal, it will automatically resume operation.

[0029] When the AVCS system is in operation, the control mode is automatic control by the automatic control module. When the automatic control strategy fails to converge, the system enters the "control anomaly" condition, and the control anomaly handling module starts and locks the automatic control mode.

[0030] Manually restore abnormal states;

[0031] S3 system functional module enable judgment

[0032] After S1 data identification and S2 system interlocking and control anomaly handling preparation are completed, the AVCS system executes the functional module adjustment function according to the enabling status of each functional module; the adjustment process and results are recorded in the system log; each adjustment result is verified for success or failure, and an operation anomaly is recorded when the adjustment fails; if the automatic mode adjustment fails to converge multiple times in a row, an operation anomaly is recorded.

[0033] S4 system automatic / manual control mode judgment

[0034] When the S3 system determines that there is no control abnormality or control lockout, it enters the mode determination stage. When both the manual / automatic knob and the touch screen are in automatic mode, the automatic control system process is executed; when either the manual / automatic knob or the touch screen is in manual mode, the manual control system process is executed.

[0035] S5 execution system regulation and control

[0036] AVCS system regulation and control are performed by running the monitoring module:

[0037] The steps for controlling the permissible vibration velocity value are as follows: Track the swing data of the vibration swing sensor 1 on the active vibration reduction and noise reduction base. When the comprehensive swing result data is greater than the permissible value of the vibration velocity of the vibration isolation object, start the electromagnetic brake 3 to control the vibration velocity value.

[0038] The steps for controlling the permissible vibration displacement value are as follows: Track the displacement data of the vibration swing sensor 1 on the active vibration reduction and noise reduction base. When the comprehensive displacement result data is greater than the permissible value of the vibration displacement of the vibration isolation object, start the electromagnetic brake 3 to control the vibration displacement value.

[0039] The steps of transmission rate control are as follows: In automatic control mode, the data of vibration swing sensor 1 on the active vibration damping and noise reduction base is tracked, and the data result of active vibration isolation transmission rate is calculated. When the calculated result data is greater than the allowable value required by the national standard, the electromagnetic brake 3 is activated to control the transmission rate.

[0040] The steps for start-stop state control are as follows: collect data from the current transformer, determine the operating state of the vibration isolation object by observing the current changes of the vibration isolation object, and control the start-stop state of the electromagnetic brake 3.

[0041] The steps for resonance range control are as follows: By determining the start-up and shutdown status of the vibration isolation object, the vibration velocity value, and the vibration displacement value, the AVCS system provides a recommended curve value for the resonance range, which is then written into the control parameters by the user; when the vibration isolation object starts working and enters the resonance range, the electromagnetic brake 3 is activated for control.

[0042] Compared with the prior art, the present invention has the following technical effects:

[0043] (1) The vibration reduction and noise reduction base of the present invention reduces and lowers the damage and noise caused by the rigid structure when the equipment is working by setting a damping spring 9 between the transverse partition 7 and the vibration reduction positioning seat 12.

[0044] (2) The present invention transmits the displacement and swing data measured by the vibration swing sensor 1 on the active vibration noise reduction base and the pressure data collected by the pressure sensor 2 to the edge controller 13 and analyzes, processes and controls the collected data through the AVCS system. The control is carried out according to the user-defined allowable vibration value range. When the allowable vibration value is exceeded, the electromagnetic brake 3 on the base is actively triggered to clamp and limit the vibration. The triggering time of the electromagnetic brake 3 is different for different vibration values. The vibration effect after braking is fed back, and the data is obtained in a timely manner to accurately control the vibration.

[0045] (3) The edge controller 13 has the ability to store sensor data locally and on the cloud platform. The AVCS system performs data filtering and data smoothing preprocessing on the stored displacement, sway and pressure data through the data identification module. Based on this, the optimal active control noise reduction strategy is obtained. The AVCS system executes the AVCS system adjustment control vibration reduction and noise reduction base according to the enabling status of each functional module, so as to achieve a good active vibration reduction effect and avoid vibration damage to the vibration reduction object.
