Description
Technical field
The utility model relates to nature lightning inspecting and recording field, particularly a kind of lightning discharge three-dimensional path automatic production record that is applied to ancient buildings.
Background technology
Chinese ancient architecture is the precious legacy of Chinese time-honoured, and due to chaos caused by war and artificial destruction, it is precious that the cultural relics and historic sites of only depositing just seem.In the disaster that wrecks of building, thunder and lightning is major casualty in ancient times, over the past thousands of years ancient architecture be struck by lightning or because of thunder and lightning event of being destroyed by fire on fire too numerous to enumerate.The reason of searching to the bottom is not only because for modern architecture, the lightning protection of heritage buildings does not arouse enough attention, generally by national thunder-strike prevention standard < < Code for design of lightning protection of buildings > > (GB50057-1994, 2000 editions) as heritage buildings lightning protection operative norm, there is no a set of perfect thunder-strike prevention standard for heritage buildings feature, especially because for a long time, people do not have the optical image data of abundant accurate direct stroke heritage buildings yet, to support analysis on accident cause (the particularly accurate inquiry of lightning strike spot after thunderbolt, to find out as early as possible damaged condition, take in time effective reclamation activities and by data accumulation, find out the weak link of lightning Protection Design).Most thunderbolt heritage buildings record is all to damage vestige and be struck by lightning judging whether by find afterwards, if but thunderbolt degree is light or direct stroke is struck by lightning with regard to bad judging whether to lightening protection installation, and the method has higher blindness.The existing lightning(-stroke) recorder being connected with heritage buildings lighting proof strip that adopts records the way of whether being struck by lightning at present, but widely distributed because of lighting proof strip, can not accurately find the particular location of thunderbolt after being struck by lightning.
The article " location technology of transmission line lightning stroke trouble spot and application thereof " that the transmission of electricity of < < Guangdong and power transformation technology > > the 6th phase in 2007 deliver, introduced a kind of technology transmission line lightning stroke trouble spot being positioned with lightning location system, the localization method that lightning location system has been used directed location to combine with time difference location, its positioning precision and location model, gps clock error, the Effect on Detecting of telemetry station, the many factors such as detection range and topography and geomorphology is relevant.In Guangdong Province's lightning location system, the positioning precision of In Guangzhou Area is relatively high, is about ± 0.78km.This positioning precision is for widely distributed transmission line lightning stroke trouble spot inquiry, significant, can help circuit patrolman to find out fast lightning failure point, reduces the economic loss of bringing because of thunderbolt.But for the less heritage buildings of distribution yardstick and heritage buildings group (as the Forbidden City plane distribution is rectangle, 961 meters long from south to north, thing is wide 753 meters), because positioning precision is not enough, the method is just inapplicable.
