Paper Abstract

The possibility of connecting sensor and actuator systems to complete networks has led to new hardware/software structures in industrial applications. Smooth integration of high bandwidth optical sensors and devices into such systems was an almost impossible task due to problems of interfacing optical components to available bus systems with transfer rates below 1 Mbit/s. Attempts are going on to build up high bandwidth deterministic bus systems that deal with enormous data rates e.g. given by visual sensors like cameras. This would lead to even worse problems in processing all the data in central computing units. This paper introduces a new concept of how to connect high data rate optical devices to currently available low cost bus systems. The concept is based on dramatically reducing data rates by supplying sensor/actuator peripherals with their own adequate computing power. Raw data transfer is replaced by doing intelligent communication within the interconnecting network on a higher level of abstraction. Computing power moves into periphery making raw sensors intelligent ones. The paper shows that the system of interconnected intelligent sensors offers a high degree of efficiency, flexibility in connecting the parts together and scalability in a natural manner. The paper figures out that integration of optical high bandwidth devices into networking systems is no longer impossible. The reduction to an absolute minimum of communication effort allows the usage of cheap well known bus systems which leads to high acceptance in industry.
