Method for constructing risk monitoring and early warning tool for vehicle-mounted hydrogen system of fuel cell

The invention relates to a method for constructing a risk monitoring and early warning tool for a vehicle-mounted hydrogen system of a fuel cell. The method comprises the following steps: constructing an equipment database and a hydrogen leakage database of the fuel cell vehicle-mounted hydrogen system; processing the equipment database by using a minimum cut set algorithm to obtain a first risk evaluation result, and performing physical analysis on the hydrogen leakage database to obtain a second risk evaluation result; and comprehensively processing and displaying the first risk evaluation result and the second risk evaluation result. The risk of the vehicle-mounted hydrogen system can be monitored and early warned, guidance is provided for safety management of the hydrogen fuel cell vehicle, and development, popularization and application of the hydrogen fuel cell technology can be promoted. 本发明涉及一种燃料电池车载氢系统风险监测和预警工具构建方法。该方法包括下述步骤：构建燃料电池车载氢系统的设备数据库，以及氢气泄漏数据库；使用最小割集算法处理设备数据库得到第一风险评价结果，对氢气泄漏数据库进行物理分析得到第二风险评价
