摘要
报警系统的报警阈值对报警性能影响很大,合理的设计出报警系统的报警阈值是我们研究报警系统技术过程中的重要问题。文中给出一种状态空间下的基于复杂报警系统性能指标的设计方法,这种方法利用预先定义的包含不确定因数的轨迹模型,权衡报警和无报警之间的关系,以此来设定合适的报警门槛值;最后,以近地告警系统(GPWS)模式1的门槛设置为例,用MonteCarlo方法在MATLAB环境中进行计算机仿真,研究报警系统使用计算机得到报警阈值的方法。
The threshold of Alerting systems has great impact on the warning performance, and a reasonable warning threshold is of great importance to the warning system. A method based on performance index of complicated warning system in the state space is proposed in this paper, in order to gain the reasonable threshold, and a track model with uncertainty factors which was defined in advance is used to balance the relationship between warning and no warning in this method. In the end, an example of setting threshold for the model one of GPWS is given, in the MATLAB simulation, it uses Monte Carlo to analyze how to gain threshold of warning system with computer technology.
