摘　　要：以武汉体育中心游泳馆屋顶网架结构为工程背景,设计了网架结构安全预警系统中的积雪自动报警子系统。该系统通过在网架结构易积雪的天窗处布置应变传感器采集应变信息,采用模糊模式识别理论,实时自动识别作用在网架结构天窗处的积雪厚度,及时告知用户,达到对该网架结构的积雪厚度进行安全预警的目的。Taken Wuhan natatorium roof space truss structure as engineering background, the snow load identification auto alarm sub-system of space truss structure safe early-warning system was designed. The snow load was identified real-timely by fuzzy pattern recognition theory based on data-acquisition from the strain gauges, which were installed on the skylight, since it was opt to accumulating snow in snowy days. It successfully realized that recognition of snow load and auto alarm for security of the space truss structure by informing the consumer timely.
