The ultrasonic automatic leveling system is based on advanced
micro-processing technology and adopts CAN-bus technology to ensure
the safety of the system to the greatest extent. It is suitable for
special working conditions such as strong electromagnetic
interference, high temperature, high humidity, and high dust on the
engineering site, and the work is more stable. , is a flexible and
efficient control system. Ultrasonic leveling system is an
important supporting instrument for paver. In recent years, it has
gradually replaced other traditional leveling instruments,
providing a stronger guarantee for road machinery to further
improve the construction quality.
features
System performance characteristics:
1. The interface of the system is equipped with fault tolerance and
overload protection functions to prevent the instrument from being
damaged by interface errors or load short circuits.
2. The system software can be upgraded indefinitely.
3. The system has working status indication and fault
self-diagnosis function, and the sensor or cable fault is clear at
a glance.
4. When the system fails, it will automatically lock the cylinder.
Institutional Features:
1. Foldable stand
2. It is convenient to adjust the position relative to the paver
3. Large-scale high-strength aluminum alloy square tube ensures
rigidity and lightness
4. Unique shock absorber
Controller Features:
1. The 8448 balance beam controller adopts a large-size color LCD
screen, intuitive icon indication, and a very good man-machine
control interface.
2. Touch button design, convenient and quick operation. Ultra-high
brightness LCD screen, suitable for outdoor use under strong light.
3. It adopts digital control mode and forms a control network with
sensors using the CAN-bus protocol. It is compatible with various
CAN digital sensors on paver and milling machines, such as
longitudinal slope, transverse slope, and cable sensors, and has
strong scalability. .
4. The LCD screen displays real-time data, and all operation
interfaces are in Chinese or graphical prompts, making it easier to
master and more convenient to use.
5. The system has its own self-diagnosis function, and the faults
of the system are clear at a glance on the display.
6. It is completely interchangeable with the same type of imported
brand products and can be used for paver, milling machine, grader
and other equipment.
principle
The principle of the balance beam: the sensor measures the road
surface at multiple points, and sends it to the controller through
CAN-bus transmission, and the controller further calculates the
measured data (combining the data measured by the three sensors
with the ambient temperature function for comprehensive processing
to obtain a Deviation value), output electric signal to control the
leveling cylinder, so as to achieve the purpose of automatically
controlling the action of the leveling cylinder.
