水上搜救系统（水上生命探测仪）——落水救援，分秒必争
据4月3日新华社报道，近期，全国各地气温迅速回升，汛期即将来临，溺水事故进入高发期，广西、云南、海南等地先后有多名学生溺亡，令人痛心。国务院教育督导委员会办公室3日发布2020年第1号预警，提醒各地教育部门和学校要高度重视，会同有关部门进一步强化防溺水工作，确保学生生命安全。
溺水事故是造成学生非意外死亡的最大原因，溺水事故频发，悲剧一再重演。溺水危害非常大，落水4-6分钟后，即使被救起，神经系统也会受到不可逆的损伤。落水超过10分钟，就几乎无生还的可能。
正所谓，溺水事故猛于虎，在防止溺水死亡事故的强化防止工作中，主要有几个方面：
一、全面排查整治隐患，把事故扼杀在发生的源头，各个行政区、村要按所属地管理，对辖区内水域开展安全隐患大排查，分析以往辖区内溺水事故发生的原因、总结针对性救援方案。
二、大力宣传，深入校园开展安全教育活动，提高学生的防范意识，进一步加强与家长的沟通联系，使家长切实履行对未成年人的监管职责。
三、大力提升救援能力，进一步完善应急处置机制，添置必要救援器材，坚决防止因出警不及时、处置不果断而耽误救援时间。
在溺水事故中，尤其是夜晚落水，造成的死亡率也相对较高。夜晚水面能见度低，如果碰上雨天和雾天，这大大增加了救援的难度，而救援时间刻不容缓。如何能升级救援设备，使救援难度降低，救生几率提高呢？
“夜通航”水上搜救系统应运而生，针对落水救援，广州恒威自主研发并生产了，水上系统（水上生命探测仪）整合多个行业中顶尖的光电一体化技术，集高灵敏度红外热像仪、电调镜头、激光模组、微光摄像机、高清自动聚焦摄像机、四仓体护罩、高速云台等于一体，结合多功能显控一体机使用，可在完全黑暗或一般雾霾的环境下快速搜寻到水面上的落水人员。高灵敏度红外热像仪结合DDE图像增强算法可在夜晚或雾霾天快速发现漂浮在水面的搜救目标；30倍变焦200万高清摄像机在白天的搜寻效果更佳，晚上由激光红外进行补光可看清远距离水上落水人员的特征；其中两个300万微光摄像机功能卓越，无需配灯在较黑暗的环境中也可实现24小时大视场角全彩监控，只要有一点点光线，夜视效果更佳。真正实现全天候监测和拍摄取证。
白天监控距离：在能见度10公里以上时，可识别距离2000米左右的船(24mX8m)，识别距离600米左右船上站立的人（1.8m*0.5m）：可识别距离150米左右落水的人员；
夜晚监控距离：在温度+25°、65%RH时，可识别距离2000米左右船(24mX8m)，识别距离400米左右船上站立的人（1.8m*0.5m），识别距离150米左右落水的人员。
拥有水上搜救系统，就如同有了千里眼，在水面快速辨认落水人员的准确位置，也为落人人员争夺了几分生的希望。
