Conclusion
|
A sensor system as described in this document establishes a way of traffic detection withsolely fiber optic components at all places where informations are acquired and on all paths they are transmitted along. All electrical components are either indoor or incorporated in housings which offer optimal possibilities for shielding and fusing. Data transmission across any considerable distances is performed using one single optical fiber pair.
The system is not yet defined down to the last detail. Aside from the fact that this was not feasible within the available amount of time it also does not appear to make much sense in the present case. The latter is due to the exceptional low effort for an exceptional high number of possible modifications.
It can be clearly stated that a system of this kind is open for a whole variety of special requests which might not even result in considerable extra costs. The version described is extremely simple; there is no need to shy away from a little more complexity. Much more complexity is less recommendable because this would come at the expense of flexibility and versatility which a system like this exhibits to a great extent.
Thus, the convenience of operating fiber-optic sensor systems, in general the ? of applying the underlying basic principle can be optimized to a high level if one succeeds in striking a balance between overdone simplicity and an excess of less important features. |
