Abstract
The present invention relates to a kind of external force to destroy evidence-obtaining system, and its technical characterstic is：Including power supply, induction coil, control unit and video recording equipment, the induction coil is arranged near wire, and the output end of the induction coil is connected with control unit, and the current signal of induction coil is exported to control unit；The output end of described control unit is connected with video recording equipment, and the control unit decides whether to start video recording equipment according to current signal；The output end of the power module is connected with control unit, and is its power supply.The present invention only can start work immediately after breaking down, and the position broken down is recorded a video, and obtain the image data for the very first time of breaking down, and the subject of offense for destroying electric power facility and violation of law are retained into evidence obtaining.
Description
Technical field
The invention belongs to line security and construction safety warning technical field, especially a kind of external force destroys evidence-obtaining system.
Background technology
In real work, big machinery lower situation about working online is often had, although our staff hand over to it
For powered scope and operating consideration, still there can be staff's supervision because of all working scene can not be accomplished.Much
Big machinery driver is to paying attention to safely deficiency, once because other side's work is appropriate to cause line outage, equipment loss, economic damage
Lose, even personal safety damage, often face the awkward situation of no evidence.Therefore, when circuit is because of short fault outage, immediately
Having video recording equipment to be actuated for scene evidence taking is extremely necessary.
But the anti-external force supervision equipment of tradition is that uninterrupted monitoring in real time is carried out to external force hidden danger point, and whole system needs to continue
Work, the data overwhelming majority higher to system power supply, image storage, data transportation requirements and acquired is useless
's.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reasonable in design, convenient and practical and can be
The external force for starting video recording evidence obtaining during line fault destroys evidence-obtaining system.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of external force destroys evidence-obtaining system, including power supply, induction coil, control unit and video recording equipment, the line of induction
Circle is arranged near wire, and the output end of the induction coil is connected with control unit, and the current signal of induction coil is exported
To control unit；The output end of described control unit is connected with video recording equipment, and the control unit is according to current signal decision
No startup video recording equipment；The output end of the power module is connected with control unit, and is its power supply.
Moreover, the video recording equipment uses the standby video recording equipment of portable length, and it is installed on shaft tower.The present invention's
Advantage and good effect are：
The present invention can start video recording evidence obtaining in line fault；Do not work in normal state, only after breaking down
Start work immediately, the position broken down is recorded a video, obtain the image data for the very first time of breaking down, electricity will be destroyed
The subject of offense and violation of law of power facility retain evidence obtaining.
Brief description of the drawings
Fig. 1 is the internal circuit block diagram of the present invention；
Fig. 2 is the process chart of the present invention.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing：
A kind of external force destroys evidence-obtaining system, as depicted in figs. 1 and 2, including power supply, induction coil, control unit and video recording
Equipment, the induction coil are arranged near wire, and the output end of the induction coil is connected with control unit, by induction coil
Current signal export to control unit；The output end of described control unit is connected with video recording equipment, the control unit according to
Current signal decides whether to start video recording equipment；The output end of the power module is connected with control unit, and is its power supply.
In the present embodiment, the video recording equipment uses the standby video recording equipment of portable length, and is installed on shaft tower.
The present invention operation principle be：
Dangerous operation under line is found during line walking, is tried in vain to talk out of doing sth., and we can not accomplish that special messenger uninterruptedly keeps a close safeguard for 24 hours
When, the standby video recording equipment of portable length can be installed on shaft tower, focus is once line outage nearby, video recording equipment start
Work, up to staff's pass hull closure or automatically power off.
The present invention is divided into sensing part, control section and video recording part；
Wherein, video recording equipment is arranged on distance of wire certain distance and can photographed on the position of working site.Video recording
The triggers circuit of equipment senses this electric field around lower wire by induction coil.Its course of work, as shown in Fig. 2 working as
In the presence of electric field continues, electric signal is produced in coil, prevents video recording equipment from starting.When accident generation, line outage, induction coil
Interior prevention electric signal disappears, and triggering video recording equipment works automatically, starts to record a video in time.
Video recording is partially installed on shaft tower, and its visual field can cover working site dangerous below wire, sensing part
Within distance of wire certain distance, wire can produce alternating magnetic field in normal operation, and coil can produce in this
Electric current, control section decide whether to start video recording equipment according to the current signal.When accident generation, line outage, induction coil
Interior electric signal disappears, and triggering video recording equipment works automatically, starts to record a video in time.
It is emphasized that embodiment of the present invention is illustrative, rather than it is limited, therefore present invention bag
Include and be not limited to embodiment described in embodiment, it is every by those skilled in the art's technique according to the invention scheme
The other embodiment drawn, also belongs to the scope of protection of the invention.
