Description
Technical field
The invention belongs to radionavigation fields, specifically, it is logical to be related to a kind of detection Big Dipper emergency position-indicating radiobeacons
The method for interrogating performance.
Background technology
30 divide when 1 day 21 June in 2015, are under the jurisdiction of the star pleasure boat in the east of Chongqing Eastern Shipping Lines, Incorporation, are sailed from Nanjing
It dashes forward on the way toward Chongqing and meets rare strong convective weather, sink in Yangtze middle reaches Hubei Jianli waters.After shipwreck event occurs, traffic fortune
Defeated department, liberation army, People's Armed Police and public security cadres and police, riverine provinces and cities etc. assemble mobilized large quantities of professional rescue workers, liberation army,
People's Armed Police and firefighters and the riparian area masses take aerial cruise, the water surface to search and rescue, underwater search and rescue, searched and rescued into cabin and full stream
The mode being combined is searched and rescued in domain, carries out comprehensive, three-dimensional, hauling type search in spot and downstream waters.Due to the
One time obtained alarm signal, and recovery force can not rush for the site of an accident at the first time, and search and rescue are very passive.By 2015
It on June 13, in, verifies through each side concerned, confirm one by one repeatedly, 454 people are shared on " star in east " number passenger steamer, wherein successfully obtaining
12 people, wrecked 442 people are rescued, whole victim's remains have been found, and search-and-rescue work terminates since then.
Live maritime sector relevant expert introduces, and " star in east " does not send out emergency alarm when turning over and sinking.According to Department of Transportation sea
Upper search and rescue center stakeholder introduces, and by regulation, Big Dipper emergency position-indicating radiobeacons should be carried on ship, after foundering, from
It moves out and climbs up on top of the water, ground station sends an SOS.But the equipment itself is immature, and rate of false alarm is relatively high, this time may be used
It can not send an SOS accurately.If ship moment turns over and sinks, Shipping Specialist is possible to have little time to send an SOS.
For in " star in east " event, the jejune problem of emergency radio Big Dipper emergency position-indicating radiobeacons technology,
The detection method of existing emergency radio Big Dipper emergency position-indicating radiobeacons only detects self performance and ignores asking for communication performance
