摘要
A method and system for monitoring sensors of a lighting control system. The method comprises performing a training of a plurality of sensors of the lighting control system (210) to determine a joint probability distribution function (PDF) of the illuminance at a given time t; collecting parameters from the training and storing the parameters in a prior data storage (S212); observing illuminance of the plurality of sensors (S222); determining if there is at least a faulty sensor from among the plurality of sensors based in part on the parameters stored prior data storage (S224); and locating a faulty sensor based on the determination of the existence of the at least a faulty sensor and the prior data (S232, S234).
