Spica – Container detector

 

APPLICATION

SPICA is an optical sensor which detects container prior to handling with a container crane.

Applications of SPICA are numerous especially for container terminal automation :
- Container position detection prior to hoisting
- Container position detection prior to stacking
- Gap between containers detection
- Container size detection.

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

MEASUREMENT PRINCIPLE

1D DETECTOR : One optical head 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 the container’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 central computer can receive up to 6 sensors and combine these measurements to do a multiple degrees measuring system.

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

Sensors and central calculator are perfectly protected in a special steel housing to avoid any damages. Steel protection with rubber silent blocks against vibrations and shocks were tested in CNES Laboratory in Toulouse – France dedicated to Space Industry.
