Spica – Optical detector for steel workshop

 

APPLICATION

SPICA is an optical sensor (or detector) which could be used in steel workshop for several applications :
- Coil detection prior to handling with an OHB crane
- Positioning of bridge crane on both axis X & Y
- Restriction of certain areas for safety reasons (i.e. avoiding all collision hazards between a load being moved and the operator control cab on the ground)

SPICA sensor is associated to a central calculator designed to be connected to 6 sensors and directly linked to the OHBC’s PLC through an RS422 serial line.

MEASUREMENT PRINCIPLE 

MEASUREMENT PRINCIPLE1D DETECTOR : One optical sensor integrates an infrared light which lights in a fan way around its vertical axis.
The emission standard angle is +/-8°.
In the other direction the beam is very narrow.
A receiver analyzes the received light and checks the reflection shape.
The internal processor analyzes the light and gives the angular position of object’s edge regarding the sensor optical axis: detection of square objects.
In an other functioning way the processor searches main line : detection of a cylindrical object.

Multiple detectors : A calculator can receive up to 6 optical sensors and combine these measurements to do a multiple degrees measuring system.
As an example three optical sensors can position a coil on both axis X,Y.  
The information received from the sensors allows the complete 2D positioning.

Environment : SPICA detectors are designed to work in a very harsh environment : shocks, vibration, humidity, temperature.
