摘要
设计了基于1-WIRE总线的火灾监测系统,采用温度、烟雾、红外传感器进行火灾检测。在数据处理方法上,首先应用模糊数学中隶属函数的概念产生各个传感器的信度函数分配,再利用D S证据理论方法对多个传感器进行数据融合,利用目标模式的判定规则对火灾的有无进行判断,较单个传感器相比,多传感器数据融合的结果具有较高的准确度和可信度。
A fire detecting system based on 1-WIRE bus is designed.It adopts temperature,smog,infrared sensors to detect fire.In the aspect of data processing,the concept of subject function in fuzzy mathematics is first used to produce belief function assignment of each sensor, and D-S evidential theory method is used to fuse multi-sensor data.The judge rule of target mode is used to decide the existence of fire.Comparing with the single sensor,the result of multi-sensor data fusion has higher accuracy and confidence level.
