Fire alarm method and system, readable storage medium and computer equipment

Abstract

The invention provides a fire alarm method and system, a readable storage medium and computer equipment, the method is applied to a fire alarm device provided with a plurality of data sensors, and the method comprises the following steps: constructing a neural network model; performing trend decomposition on the dimension data of each data sensor to obtain a detrending sequence and a detrending sequence set; obtaining an attention weight according to the similarity coefficient of each detrending sequence and the detrending sequence set, and obtaining a detrending correction sequence set through the attention weight; residual data are obtained according to the detrending correction sequence set, a loss value is evaluated for the residual data, and a neural network performs reverse transmission and calculates a descent gradient layer by layer; optimizing parameters of the neural network model according to the descent gradient, performing repeated iteration on the data of each dimension, and outputting a probability value after iteration after triggering a termination condition; and judging whether a fire occurs or not according to the iterated probability value and the fire probability threshold. According to the invention, the alarm accuracy can be improved, and misjudgment is reduced.

Description

Technical field [0001] The invention involves the field of data processing technology, and specially involves a fire alarm method, system, readable storage medium and computer equipment. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the demand for domestic electricity and corporate power consumption is increasing.As one of the main ways to transmit electricity, the reliability of power cables is of great significance. As the cable's laiding range is getting wider and wider, the power outage caused by the damage of the cable is also high.one. [0003] The temperature control in the cable groove plays an important role in the safety and reliability of the entire operating system. In order to prevent cable damage to prevent cable trenches, the automatic alarm system is usually added to the cable groove. [0004] The automatic alarm system in the existing technologies is not highly reliable in the internal se...

Problems solved by technology

[0004] However, due to the low reliability of the internal sensors and poor applicability to harsh environments, the automatic alarm system in the prior art often produces misjudgments when monitoring and alarming the cable trench temperature in harsh environments, resulting in monitoring Personnel are unaware of the alarm, so it is difficult to detect and effectively control the fire in the early stage. Therefore, in view of the situation in the cable trench, the watchman still patrols daily; and the available period of the automatic alarm system in the prior art is relatively short , which also causes great difficulties for maintenance
