Event.
If identity authentication result is not pass through, which is abnormal event, i.e. illegal operation is anti-electricity-theft at this time
Device starts the camera function of image detection module 102, and by the image transmitting of shooting to server 105, for example, logical by 4G
Unit is interrogated by Image Real-time Transmission to server 105, for example, the pixel resolution of image can reach 1024 × 768, but not office
It is limited to this, and will be uploaded after the image encryption, prevents other people malicious modification.
It is then detected that being more than the magnetic field of the first preset value in batch meter with the presence or absence of magnetic field intensity, for example, the first preset value
Illustrate that there are high-intensity magnetic field electricity stealings if there is the magnetic field more than 2T in batch meter for 2T；If the magnetic field intensity in batch meter
Under in 2T, then be not present high-intensity magnetic field electricity stealing.Field detection result is transmitted to server 105, and by the magnetic field detection
As a result it is uploaded after encrypting, malicious modification is carried out to it with anti-electricity-theft personnel.
It is then detected that being more than the electric shock of the second preset value in batch meter with the presence or absence of current strength, for example, the second preset value
Illustrate that there are strong electrical shock electricity stealings if there is the electric current more than 10mA in batch meter for 10mA；If the electric current in batch meter
Less than 10mA, then strong electrical shock electricity stealing is not present.Electric shock detection structure is transmitted to server 105, and the electric shock is examined
It is uploaded after surveying result encryption, malicious modification is carried out to it with anti-electricity-theft personnel.Finally, according to the figure in the server of acquisition 105
Picture, field detection result and electric shock testing result, carry out comprehensive analysis, to judge whether electricity stealing.If there are stealings
Behavior is then carried out investigations by related personnel.
In the utility model embodiment, by judging the unlocking behavior of operating personnel；And based on shooting image,
Field detection result and electric shock testing result pass through judge to be combined twice to whether being stored in electricity stealing and judging
Mode judges electricity stealing, improves the accuracy and reliability of electricity stealing judgement, is risen to specification power consumption management
To prodigious facilitation, the management level of power grid is substantially increased.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
