Abstract(s)
Irrigation is one of the most consuming water resources in human activity. As water
conveyance systems are commonly spatially distributed and crossing large regions it is important
to guarantee their best efficiency. A fault diagnosis architecture is an important tool to increase
efficiency in water conveyance systems. In the presence of leaks, unauthorized water extractions
or water level sensor faults, the service level can be severely compromised. Recent literature deal
with these situations as a unique fault of water extraction type. Isolating correctly each fault is
important to access the real current state of the irrigation canals and proceed in accordance to
restore its nominal conditions. This paper proposes a fault diagnosis architecture to distinguish
common faults in water canals, considering either unexpected water extractions, gate faults and
downstream water level sensor errors. The architecture is based on geometric and hydraulic
parameters and therefore can be extended to existent irrigation canals. The proposed fault
isolation architecture is an important tool to support maintenance services and be extended to
fault tolerant controllers.
