Electric automobile charging and replacing station fire risk data evaluation method

Abstract

An electric automobile charging and replacing station fire risk data evaluation method includes the steps: numerically simulating actual acquired data of fire scene main structures of a distribution room, a charging and replacing room and a monitoring room in an electric automobile charging and replacing station by a modeling tool to obtain a large number of simulated data, and screening or exhausting the fire development condition of a single room after catching fire and influence factors of the fire on the whole charging and replacing station; determining a data evaluation range; building a fire risk data hierarchy structure model; calculating the weight of each factor by a hierarchy analysis method; determining fire risk levels; judging whether the fire risk levels meet safety requirements or not, if the fire risk levels do not meet the safety requirements, calculating improving suggestion data according to fire risk and harmfulness obtained in the first step, returning to the fourth step according to the proposed suggestion data, reconstructing a judgment matrix, calculating the weight and performing evaluation until meeting evaluative criteria. Reliable data can be provided, and prediction accuracy is improved.

Description

technical field [0001] The invention relates to a data processing method, in particular to a data processing method for existing building structures. Background technique [0002] The electric vehicle charging and swapping station is an important infrastructure in the development of electric vehicles. As a comprehensive electrical facility, it includes oil pipelines, high-voltage power grids, battery packs, and mixed mechanical structures, power distribution rooms, charging and swapping rooms and Any negligence in the monitoring room may cause a potential fire hazard. The existing fire alarm mode usually monitors the fixed hidden danger location, monitors the environmental parameters of the collector, and starts fire extinguishing or alarm at the corresponding location according to the monitoring signal. However, the conventional model does not take into account the frequent energy conversion in the charging and swapping station where the energy is concentrated, and the swi...
