The feedback adjustment module sends a signal to the hydraulic device, instructing it to increase a specific height, and three adjustment heights are set: 10 cm, 20 cm, and 30 cm. The hydraulic device precisely controls the movement of the piston according to this signal to reach the required height. The electric adjustment device adjusts the height of the support structure by driving a screw or a gear system with a motor.
[0130] Angle adjustment: Adjust the angle of the monitoring instrument support structure according to the specific tilt anomaly level of each sub-region. If the tilt anomaly level is high, stabilize the monitoring instrument by adjusting the angle of the support structure to ensure it remains horizontal. The specific implementation of angle adjustment is completed by mechanical structures such as a rotating device or a tilt adjustment device. The rotating device drives a rotating platform with a motor to adjust the angle of the support structure. The feedback adjustment module sends a signal to the rotating device, instructing it to adjust a specific angle, and three adjustment angles are set: 5°, 10°, and 15°. The rotating device precisely controls the rotation of the rotating platform according to this signal to reach the required angle. The tilt adjustment device adjusts the angle of the support structure hydraulically or mechanically. The feedback adjustment module sends a signal to the tilt adjustment device, and the device performs mechanical operations according to the signal to precisely adjust the angle of the support structure.
[0131] The feedback adjustment module sends an electrical signal to the motor control system, and the motor rotates a corresponding angle or distance according to the signal, thereby precisely adjusting the height of the support structure.
[0132] In one embodiment, it further includes:
[0133] When the vibration anomaly level or / and the tilt anomaly level reaches the severe level, an alarm signal is triggered, a personalized report is generated, and the alarm signal and the personalized report are pushed to the control terminal of the monitoring center.
[0134] Replacement of sensor nodes: In addition to using vibration and tilt sensor nodes, other types of sensors such as acceleration sensors and displacement sensors can also be used to monitor the changes on the dune surface.
[0135] Replacement of data transmission module: The wireless transmission module can be replaced by a wired transmission module, and data is transmitted through optical fibers or cables to ensure the stability and reliability of data transmission.
[0136] Replacement of adjustment device: In addition to being achieved through hydraulic devices and electric adjustment devices, the adjustment of height and angle can also use other mechanical structures such as pneumatic devices and stepper motors to achieve precise control of the height and angle of the support structure.
[0137] Replacement of anomaly handling mechanism: In addition to generating anomaly signals and performing automatic adjustment, a manual intervention link can be added. Through the remote control system, the monitoring personnel can manually adjust the height and angle of the monitoring instrument.
