An Inspection Method for Sensors Installation Faults in Air Conditioning Systems by Stochastic Qualitative Reasoning

摘要

This paper presents an inspection method by means of stochastic qualitative simulation for sensor installation faults in air conditioning systems. Sensor installation faults often occur in newly-constructed or newly-maintained systems. Since the installation faults of snesors present themselves in the form of changes of measured values, we have proposed the follwing inspection method for sensor installation faults: First, construct a qualitative model based on the specifications. next, modify the measured values acocridn gto the assumed sensor installation faults. Finally, identify the faults by using stochastic qualitative reasoning. This method will be demonstrated by applying it to an air conditioning system.
