The construction of block；
Wherein, the orientation safeguard is when receiving the relative direction that the angle detecting equipment is sent, based on the phase
To direction by the corresponding metal derby of the relative direction from horizontal positioned State Transferring to be disposed vertically state.
5. method as claimed in claim 4, it is characterised in that：
The default conditions of multiple metal derbies of the orientation safeguard are horizontal positioned state；
Wherein, when the relative direction is a direction scope, by the corresponding multiple metal derbies of the direction scope from level
Laying state is converted to the state of being disposed vertically.
6. method as claimed in claim 5, it is characterised in that：
The complexity that the resolution ratio of the high-definition image sends the scene in the range of radiation of equipment according to energy, which is automatically determined, also wraps
Include：The resolution ratio of the high-definition image automatically determined has the limitation of ultimate resolution threshold value and minimum resolution threshold value.
7. method as claimed in claim 6, it is characterised in that the radiation proof directional protection system also includes：
TF storage devices, are connected with described image capture device and the filtering starting device, for store preset area threshold value,
Ultimate resolution threshold value and minimum resolution threshold value.
8. method as claimed in claim 7, it is characterised in that：
The TF storage devices are also connected with angle detecting equipment, and the predeterminated position of equipment is sent for prestoring energy.
