Optical Distance Measurement With Integrated Data Transmission

Optical measurement systems for position determination and optical data transmission systems have both proven highly reliable over the years in practical warehousing and storing applications. Leuze Electronic of Germany has now combined both these techniques in a single system. The combination device, ODM2, measures distances, for example, to determine the position of rack handling device in warehouse aisles by gauging the light transit time, and is able at the same time to optically transmit data. Procurement costs and installation inputs are drastically reduced as a result. The system operates over its entire measurement range of 0.5 to 200 m with a repeat accuracy of &241;"1.5 mm. As the measured value is made available in the form of absolute value, no reference travel process are required (eg, after a power failure). The integrated data transmission unit creates an optical bus link to a data transmission head mounted at the end of the aisle. Interbus-S and Profibus DP can be optionally used. The lens system beam angle of &241;"1.5&248;"permits travel path tolerance without interrupting data transmission. In addition, the measured value is made avaible via an SSI interface for direct processing by a position controller. The device complies with the requirement of protection class IP65 as a standard feature, and offers simple, practically oriented installation and adjustment. All important device functions can be monitored in the test mode.
