摘　　要：提出将超声波测距技术应用于火场环境侦测。介绍超声波测距原理,从理论上分别分析了温度和烟气浓度对超声波传播速度的影响。依托现有成熟的超声波测距设备对其在火场中的适用性进行了实验验证。结果证明,温度对超声波传播速度的影响不能忽略,而烟气颗粒浓度的影响不大;由于温度补偿技术已非常成熟,因此带温度补偿的超声波测距技术适用于火场高温浓烟环境侦测。Applying ultrasonic ranging technology to fire environ-ment detection was proposed.The principle of ultrasonic ranging was introduced.The influence of temperature and smoke concentra-tion on the ultrasonic propagation velocity was theoretically anal-ysed.Based on the existing mature ultrasonic distance measuring equipment,its applicability in the fire field was verified by experi-ments.The result proved that the influence of temperature can’t be ignored,while the influence of smoke concentration is small;as the technology of temperature compensation has matured,ultrasonic ranging technology can be applied to high temperature fire environ-ment detection.
