Customizable Averaging Leveling Beam for Pavers with Ultrasonic Probes
The ultrasonic balance beam is an important device used in asphalt pavers, which can effectively improve the flatness of the paved road surface.
Components:
It usually includes ultrasonic probes (sensors), controllers, brackets and beams, connection cables, etc. Among them, the ultrasonic probe is used to measure the distance from the road surface to the probe and transmits the data to the controller; the controller sends commands, receives and processes the data collected by the probe, and judges the working state of the paver based on the data, and then outputs the control signal to the leveling hydraulic system of the paver; the bracket and the beam are mechanical devices for installing the ultrasonic probe; the connection cable is used to connect each component for signal transmission.
Working principle:
The sensors (ultrasonic skids or probes) are combined through the internal CAN bus network to detect different positions of the road surface, intelligently screen and process the detected data, and then transmit the processed data to the controller. The controller judges the current working state of the paver accordingly and outputs the corresponding control signal to the leveling hydraulic system of the paver, thereby achieving the purpose of automatic leveling.
