AI Technical Summary

Technical Problem

Existing air respirator reserve prediction systems fail to effectively consider individual firefighter physiological characteristics and the intensity of fire scene operations, resulting in biased prediction results. Furthermore, they lack data feedback and long-term optimization mechanisms, making it impossible to maintain accuracy and reliability in long-term applications.

Method used

By acquiring basic information and historical consumption time data of firefighters, an individualized theoretical pressure consumption rate function is established. This function is then combined with a dynamic pressure compensation coefficient for real-time correction. Finally, a multinomial regression fitting algorithm is used to update the prediction model, enabling adaptive error correction based on individual physiological characteristics of firefighters and the fire scene environment.

Benefits of technology

It improves the accuracy and precision of air respirator reserve prediction, ensures dynamic monitoring of air volume in high-temperature and high-intensity working environments, and achieves long-term iterative updates through a data feedback mechanism, thereby improving the reliability of the system.

Abstract

The invention relates to the technical field of fire rescue equipment monitoring, and discloses a fireman air respirator allowance prediction method and system based on dynamic pressure compensation. The method comprises the following steps: acquiring historical consumption time data of a fireman, establishing a theoretical pressure consumption rate function of a corresponding individual by applying polynomial regression fitting, and determining a theoretical prediction logic; receiving a battle marshalling command to obtain an initial full-load pressure, starting timing, and calculating and displaying a current theoretical predicted residual pressure; capturing a manual interaction correction instruction, extracting a correction time node and actual residual pressure, and resolving to generate a dynamic compensation coefficient; the dynamic compensation coefficient is used for reconstructing and resolving the actual prediction residual pressure and controlling, updating and displaying; and comparing the actually predicted residual pressure with an alarm critical pressure value to trigger an alarm, and extracting actual combat data to iteratively update the theoretical function after the task is finished. According to the invention, individualized reference prediction of gas consumption and dynamic self-adaptive error correction of the working environment are realized, and the accuracy of margin early warning is improved.
