Data link is the key information system for the cooperation of weapons, single physical layer anti-jamming technology has been unable to meet its requirements. High dynamic precision-guided weapon nodes like missiles, anti-jamming design of data link system need to have stronger pertinence and effectiveness: the best anti-jamming communication mode can be selected intelligently in combat environment, in real time, guarantee the continuity of communication. We discuss an anti-jamming intelligent networking technology of data link based on interference awareness, put forward a model of intelligent anti-jamming system, and introduces the cognitive node protocol stack model and intelligent anti-jamming method, in order to improve the data chain of intelligent anti-jamming ability.
Recently, GPS has been more and more applicative in open pit mine slope safety monitoring. Daye Iron Mine open
pit high-steep slope automatic monitoring system mainly consists of three modules, namely, GPS data processing
module, monitoring and warning module, emergency plans module. According to the rock mass structural feature and the
side slope stability evaluation, it is arranged altogether to seven GPS distortion monitoring points on the sharp of Fault
F9 at Daye iron Mine, adopted the combination of monofrequent static GPS receiver and data-transmission radio to carry
on the observation, the data processing mainly uses three transect interpolation method to solve the questions of
discontinuity and Effectiveness in the data succession. According to the displacement monitoring data from 1990 to 1996
of Daye Iron Mine East Open Pit Shizi mountain Landslide A2, researching the displacement criterion, rate criterion,
acceleration criterion, creep curve tangent angle criterion etc of landslide failure, the result shows that the landslide A2 is
the lapse type crag nature landslide whose movement in three phases, namely creep stage, accelerated phase, destruction
stage. It is different of the failure criterion in different stages and different position that is at the rear, central, front
margin of the landslide. It has important guiding significance to put forward the comprehensive failure criterion of seven
new-settled monitoring points combining the slope deformation destruction and macroscopic evidence.
