Abstract:
The warehouse environment parameter monitoring system is designed to avoid the networking and high cost of traditional monitoring system. A sensor error correction model which combines particle swarm optimization (PSO) with back propagation (BP) neural network algorithm is established to reduce nonlinear characteristics and improve test accuracy of the system. Simulation and experiments indicate that the PSOBP neural network algorithm has advantages of fast convergence rate and high diagnostic accuracy. The monitoring system can provide higher measurement precision, lower power consume, stable network data communication and fault diagnoses function. The system has been applied to monitoring environment parameter of warehouse, special vehicles and ships, etc.
