Ultrasonic Automatic Leveling System SMC-8448 CANbus Communication

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.
