7. Structure and operating principle
Operation of the system is based on scanning the pipe inner surface with a rotating
triangulation laser sensor.
The system contains a base on which the linear translation mechanism, the
controller and the interface module are installed. The linear translation mechanism carries
the rotation module on which the laser sensor is mounted. On the back of the system there
are four connectors for power and interfaces.
The system operates as follows.
The measured pipe is installed coaxially with the laser sensor. At the command of
an external controller, the laser sensor moves into the hole. The sensor begins to rotate and
scans the inner surface of the pipe, transmits the polar coordinates of the surface (distance
from the axis of rotation measured by the sensor and the corresponding angle of rotation) to
the built-in computer to calculate the required geometric parameters. The result is
transmitted to the external controller via PROFINET.
8. Connection
·
Connect the system to your controller.
·
Connect the power cable to the system.
·
Connect the system to 24V DC by using the special power cable.
The block diagram is shown below. In this diagram, I-7580 module is PROFINET IO
device of the system, and PLC is S7-1200 from Siemens. The program «Step 7 V11»
provided by Siemens does the configuration and communication.
