System Architecture and cabling
The system consists of three components Measurement sensor, Controller, HMI Display.
Measurement sensor
Measurement sensor does the actual physical measurements of objects located in the laser plane Measurement sensor is connected to controller to appropriate connection interface (see below controller) with high quality cable.
Controller
The controller gets images from the measurement sensor and does the appropriate conversion and processing to geometric objects of the specified preset.
The interfaces of the controller are dedicated for specific purposes from left to right:
1. HMI display or switch to HMI and external pc.
2. Debug interface intended for servicing, remote access etc. The IP configuration is obtained by DHCP on the network where the controller is connected.
3. OFF
4. Interface to robot. Preconfigured to 10.0.0.1/255.255.255.0. IP configuration can be changed from the client.
5. SkyBlue sensor connection. 5m gray cable CAT7 and 10m blue cable CAT6A are provided.
6. Not used.
Sensor interface is POE enabled and controller is powering the sensor. IP address is factory defined and is not intended to be changed on the field.
HMI Display
Provide user interface to the controller and parameterization of pattern matching for successful seam tracking.
Multiplatform Client writen in Java
Visualize Image and world view of the observation
Adjust parameters for image quality and objects matching
Manage presets
System functions - update, logs, robot connection parameters
Internal robot simulation
Logging of images for offline processing
Control locking state of the system - locking is a special function to reduce mistakes. When one or more clients are connected to the system only one of them has writing and changing rights. When the robot activate the measurements it locks exclusively the client, but it is still possible to overrule this lock on the client side. The intention of this function is to avoid unintended change of parameters during seam tracking.
Support for Admin, Manager and User rights secured by specific pin codes.
Supported robots
Blue systems support one of the most large list of robots and protocols.
