This paper presents a new idea of ZigBee-based information acquisition system of forest fire risk.
提出了把ZigBee技术应用于森林防火的新思路,研究设计了森林火险信息采集系统,论述了基于MSP430F1232和CC2420的无线传感器网络的节点设计,介绍了基于ARM7系列S3C44B0X、GPRS模块SIM100的网关设计,搭建了平面型网络拓扑结构。
Based on the physical concept of heat energy of preignition, a new fire susceptibility index (FSI) is used to estimate the forest fire risk.
结合遥感和气象数据,基于可燃物引燃能量的物理概念,利用火灾敏感性指数(FSI)进行森林火险监测和评估。
Assessment study on fire danger rating is a meaningful way in forest and grassland management and can provide useful information to support fire management decisions.
火险等级评估作为科学防火的一个重要方法,可以为森林草原防火提供科学有效的决策支持信息。
However it can take some measures to enlarge the technological allowance amount (13 mm～14 mm),avoiding the dangerous dimensions(4 mm～12 mm) by quenching at low temperature (750 ℃～760 ℃),then controlling the tempe.
而采取加大工艺预留量(13mm～14mm)、避开危险尺寸(4mm～12mm)、低温(750℃～760℃)淬火、控制加热温度(780℃～790℃)以及保温时间和回火时间等措施,可有效防止45钢件淬火时出现裂纹现象。
