Automatic electricity-stealing-preventing electric meter

Abstract

The invention relates to an automatic electricity-stealing-preventing electric meter, which comprises a seal movement identification device, a screw variation identification device, an electric energy detection device and a main controller, wherein the seal movement identification device and the screw variation identification device are used for identifying the variation conditions of a seal and a screw on an outer frame of the electric meter respectively; the main controller is connected with the seal movement identification device, the screw variation identification device and the electric energy detection device respectively. Through the automatic electricity-stealing-preventing electric meter, the electricity stealing fact of an electric meter can be automatically detected; a relevant electric power department is avoided from further economic loss.

Description

[0001] This invention is a divisional application of a patent with the application number 201610180396.1, the application date is March 25, 2016, and the invention name is "A Method for Using an Automatic Anti-theft Electricity Meter". technical field [0002] The invention relates to the field of watt-hour meters, in particular to an automatic anti-theft watt-hour meter. Background technique [0003] The watt-hour meter is an important instrument used to measure the amount of electricity consumed by residents or factories. The power supply management department determines the specific amount of electricity consumed by the electricity consumer based on the reading of the watt-hour meter, and uses this as the basis for charging, requiring the electricity consumer to pay. [0004] It can be seen that the watt-hour meter is closely related to the economic interests of the power supply management department and the power user. If the measurement result of the watt-hour meter is n...

Problems solved by technology

[0004] It can be seen that the watt-hour meter is closely related to the economic interests of the power supply management department and the power user. If the measurement result of the watt-hour meter is not accurate, it is easy to cause the charging to be not objective enough, and the excessive charge will violate the economic interests of the power user. If the charge is too small, it will damage the economic interests of the power supply management department. Therefore, the measurement accuracy of the watt-hour meter must be accurate

[0005] At the same time, tampering with the watt-hour meter can achieve the effect of stealing electricity by changing the reading of the watt-hour meter. This is what the power supply management department does not want to see. However, since the electricity meter is mostly set in the public area near the location of the electricity consumer, it is out of sight of the power supply management department for a long time, which still provides an opportunity for electricity theft
