Air conditioning system sensor fault detection method and device and electronic equipment

Abstract

The invention discloses an air conditioning system sensor fault detection method and device and electronic equipment. The method comprises the following steps: determining system evaluation indexes, building a target function, and therefore a fitness function is determined; selecting a Gaussian radial basis kernel function and a polynomial kernel function to construct a vertical air conditioning system sensor fault detection hybrid kernel function matrix, and establishing a hybrid kernel function-based KPCA mathematical model for describing the operation state of the air conditioning system and sensor fault detection; and optimizing the hybrid kernel function parameters by using a multi-objective particle swarm algorithm to obtain fault detection optimization of the air conditioning systemsensor. According to the invention, the multi-target particle swarm optimization algorithm is introduced to solve the problem of fault detection optimization of the air conditioning system sensor, the hybrid algorithm is improved to solve the target problem, certain advantages are achieved, and fault detection optimization of the air conditioning system sensor can be achieved.
