防儿童走失系统
Child abduction alert system
全国首个防儿童走失系统6月1日在江苏南京正式启用，该系统启动后会关闭建筑物所有出口10分钟，以寻找走失儿童。
China's first child abduction alert system, which will close all the exits of a building for 10 minutes to search for missing children, came into force in Nanjing, Jiangsu, on Monday.
除关闭出口外，工作人员在搜寻儿童时，广播还将播放走失儿童的信息。
In addition to exit close, speakers will also broadcast information on the missing children while workers search for the children.
如果10分钟内未找到走失儿童，所有出口将再次打开，警方则介入调查。
