NW China province works out burglar alarm for ancient tombs
2/12/2004 16:50
Northwest China's Shaanxi Province has developed a high-tech alarm to
protect ancient tombs and other underground cultural sites from burglars.
The
alarm of the SLT125 device will sound within 30 milliseconds of detecting the
ground vibrations caused by any intruder, according to sources with Shaanxi
Letong Electronic Application Technology Co
The company has worked out the
alarm device at the request of the provincial cultural heritage bureau. The
device passed the evaluation of the State Administration of Cultural Heritage
earlier this week.
Experts with the evaluation committee agreed it is
feasible to protect underground heritage pieces and combat illegal excavations
with ground wave probing technologies.
Developers of the system say the
device ensures nearly 100 percent accuracy in detecting potential burglaries,
either through digging or use of explosives. It is also sophisticated enough to
tell the location of potential intruders from two to 30 meters
underground.
Despite the local government's recent successes in curbing
illegal excavations, occasional thefts are reported in tombs that are scattered
in the outback.
The northwestern province boasts is rich in cultural heritage
resources, particularly in the ancient capital city of
Xi'an.
