Title:
FIRE JUDGING DEVICE AND LEARNING METHOD FOR NEURAL NETWORK
Document Type and Number:
Japanese Patent JP3032402
Kind Code:
B2
Abstract:
PURPOSE: To appropriately judge a fire without using feedback by introducing temporal conception by using a neural network, and to correctly judge the fire even for pluse-like input.
CONSTITUTION: Generated heat quantity Qf, generated smoke quantity Qsmk and generated CO gas quantity Qco accompanied with the fire, and further, the respective differentiated values dQf/dt, dQsmk/dt dQco/dt of those are obtained by an input processing part provided with a sensor part 10, a mathematical model part 18, an environment coefficient weighting part 20 and a normalizing part 22, and are inputted to the neural network 24. The neural network 24 is of a hierarchical type constituted of an input layer, an intermediate layer and an output layer, and further, it is provided with a delaying part to delay an input signal in plural stages by the input layer and output it to the intermediate layer.
