UAV helps fight Nanshan Mountain Fire in Shenzhen
原标题：无人机协助扑救深圳南山山火 1月21日20时20分，深圳大南山突发山火。火势借着地势和风势向山顶迅速蔓延，不断扩散。大南山灌木、桉树和杂草茂盛，一时之间火势十分迅猛。附近正是220kV高压电网，现场情况刻不容缓。 应相关单位保障需求，大疆应急救援联盟第一时间携带无人机赶赴现场保障救援。无人机在 2分钟内装备完成，迅速起飞，深入火场，实时画面直接接入前线指挥部大屏，帮助消防指战员研判火势，高效配置地面消防力量，为扑救行动提供高效保障。 此次山火为典型的“上山火”，通常采取“从火翼夹击，把火线夹断，分段歼灭”的扑灭策略。然而在一线队伍向山顶行进时，原本扑灭的后方很可能发生复燃，或由大风带来飞火，一旦燃烧起来，火势会影响救援人员后路，造成一定安全隐患。 在无人机画面显示后方发生复燃时，指挥部指战员立即定位火点位置，连线前方，及时预警，避免一线队伍被火势包围。在指挥部指示下，多处微小火点被迅速压制。 此次山火中，消防指战员使用无人机挂载的热成像相机，通过温度差异，直接、准确地定位出了火源位置，为灭火行动，节约了宝贵时间，快速遏制火势蔓延。 在民航深圳监管局、空管站、深圳塔台和南山区公安分局的天地联动指挥调度下，直升机与无人机分工有序、配合默契，保持不同高度层实施救援与现场指挥调度，出色保障了应急救援任务。 (责编：杨虞波罗、吕骞)
