The BP nerve network has been used widely in fault detection field, but the usage of solution seeking algorithm by along gradient descent often results in low convergence speed and frequently getting into the part minimum. On the contrary, the genetic algorithm has the advantage of fast seeking speed in full-scale. Therefore, to optimize the BP nerve network, this essay adopts the auto-fit genetic...
The gas turbine unit is developing larger and automatic continuously. It has become the major units of electric network. System monitor and fault diagnosis technology have been thought much of increasing due to the complexity of system. Conventional fault diagnosis technology is replacing by intelligent fault diagnosis technology gradually. ANN (Artificial Neural Network) has been widely used in pattern...
This paper presents the design method of pan-camera decoder applying in digital video monitoring system including software and hardware. This decoder was based on embedded microcontroller C8051F330 and was mainly composed of regulated power supply circuit, serial communication interface circuit, watching dog circuit, input/output alarm circuit and pan-camera control circuit. It is connected with the...
The BP nerve network has been widely applied on fault diagnosis. The BP network due to adopt search arithmetic along grads drop, therefore there are some problems such as slow convergence rate and easily getting into local infinitesimal. The genetic algorithms has the excellence of rapid searching rate. Therefore, auto-adapt genetic algorithms is adopted to optimize the BP algorithms in the paper...
