Embodiment five
With reference to Fig. 6, show that the safety work region in equipotential live line work mode of the embodiment of the present invention and alarm region show
It is intended to.
When livewire work personnel are worked using equipotential live line work mode, the method for the invention combine corresponding safety away from
From two boundary lines delimited, one is to alert Region control line, and shown region in dotted line in Fig. 6, the first alarm region, one is
Safety work region control line, shown region, the first safety work region in solid line in Fig. 6.
If corresponding minimum safe distance is h, equipotential live line work personnel and the distance of 1 coboundary of safety zone may be configured as
0.8 (H-h), may be configured as (H-h) with the distance of the first alarm region coboundary；With the first safety work region left margin away from
From may be configured as 0.8 (S-h), may be configured as (S-h) with the distance of the first alarm region left margin.
This means that in depth camera, monitoring region is set for the first alarm region.As equipotential live line work human contact
To the first alarm region, start to alarm.
Since right margin and lower boundary do not have grounding body in Fig. 6, but operating personnel can only move on conducting wire, therefore with
The distance on border can refer to be set with the distance of coboundary, be can refer to the distance of right margin and is set with lower boundary.
Embodiment six

It is intended to.
When livewire work personnel are worked using earth potential working mode, it can still combine safe distance and delimit two borders
Line, one is alarm Region control line, and one is danger zone control line.
If corresponding minimum safe distance is h, depth camera may be configured as S-h, depth with danger zone left margin distance
Camera and the second alarm region left margin distance may be configured as 0.8 (S-h)；Danger zone coboundary may be configured as with cross-arm distance
H-h, the second alarm region coboundary may be configured as 0.8 (H-h) with cross-arm distance
This means that in depth camera, monitoring region is set for the second alarm region, when ground potential operator invades
To alarm region, start to alarm.
In fact, it is still two positions that should be noted according to ground potential operator herein, first, at livewire work personnel
In cross-arm side insulator hanging point；Second, livewire work personnel carry out positioned at shaft tower tower body place parallel with conducting wire.
When at livewire work personnel are in cross-arm side insulator hanging point and at the tower body parallel with conducting wire, at this time from waiting electricity
Position, i.e. high-tension bus-bar, distance be minimum.H is distance of the cross-arm side insulator hanging point away from high-tension bus-bar in corresponding diagram 7, S
For the distance of place parallel with high-tension bus-bar tower body.
