The invention discloses a fire detection method, device and equipment based on a neural network, and a storage medium. The method comprises the following steps: obtaining incident light signals of a plurality of training light sources; performing signal processing and analysis on the incident light signal of each training light source to obtain a spectral signal parameter, a time signal parameterand a space signal parameter of each training light source; establishing a training data set according to the spectral signal parameters, the time signal parameters and the space signal parameters ofthe training light source, and constructing a neural network model for fire detection according to the training data set; determining output parameters of a light source of the to-be-detected site according to the neural network model, and determining whether a fire occurs in the to-be-detected site according to the output parameters. According to the fire detection method provided by the embodiment of the invention, the neural network model is optimized by training the characteristic parameters of the light source, and the neural network model is used for fire identification, so the identification algorithm is simple, the data processing amount is small, the fire detection response speed is high, and the accuracy is high.

The invention discloses a corridor fireproof system with the encoding function. The corridor fireproof system comprises a control center module, a fire detection system and a fire processing system. The fire detection system comprises a plurality of fire receivers connected with different fire sensors. The fire processing system comprises a fire processor connected with different controlled devices. An air inlet system, a poison gas exhaust system and an escape room are independently arranged. The corridor fireproof system can supply fresh air to people in a fire, piston gas in a building in the fire can be effectively exhausted, dangerousness of the piston gas can be reduced, and then people has more escape time and more escape opportunities. The corridor fireproof system is further provided with an encoder, the fire receivers and the fire processor are encoded in advance, and then flexibility and applicability of the corridor fireproof system are better.
