Smart sensor is a recent concept presenting numerous advantages such as versatility, strong electromagnetic immunity, reduction of the connectivity, high computation power, etc. In civil engineering smart sensor based systems are well suited due to the large amount of spatially distant transducers and the need of large computational power. However, such systems require long development time, especially in their software part, and beside the multitude of instrumentation problems encountered, the need of a generic model is strong. The aim of the model is the design of a software generator for distributed data acquisition system. The key of our system is in the description of an instrumentation plane under the form of a data dependence graph (DDG). The goal of the generator is to map and 'execute' that DDG on the physical architecture according to the number of transducers, their affectation to the smart sensors and a PC based system controller. In this paper, after an outline of the smart sensor concept, we describe the DDG based representation of the instrumentation plan. An example of bridge monitoring is then described. Finally, the smart sensor, the system controller and the network modelization are outlined and their ability to allow the DDG mapping with the help of local or remote variable is shown.
