Embodiment Construction
[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in a variety of different ways defined and covered by the claims.
[0034] Reference figure 1 , The preferred embodiment of the present invention provides a remote anti-theft device for remotely alarming power theft on the power supply line. The remote anti-theft device includes a phase current collection unit, a user current collection unit, and a power theft The judgment unit, the phase current acquisition unit and the user current acquisition unit are all communicatively connected to the power theft judgment unit. Among them, the phase current collection unit is used to collect the phase current value on the output phase line of the power supply unit, and output the collected phase current value to the power theft judgment unit; the user current collection unit is used to collect all users supplied by the out...

The invention discloses a remote anti-stealing device and an anti-stealing method. The anti-stealing device includes a phase current acquisition unit, a user current acquisition unit and a stealing judgment unit, and the phase current acquisition unit and the user current acquisition unit are connected by communication. Stealing electricity judging unit; the phase current acquisition unit is used to collect the phase current value on the output phase line of the power supply unit, and output the collected phase current value to the electricity stealing judging unit; the user current acquisition unit is used to collect the output phase line power supply of the power supply unit The sub-current value of all users, and output the sub-current value of each user to the electric stealing judgment unit; the electric stealing judgment unit judges whether electric stealing occurs on the power supply line of the power supply unit according to the comparison of the phase current value and the sum of the partial current values . The invention judges whether electricity stealing occurs on the power supply line by comparing the difference between the phase current value and the sum of the partial current values, which greatly improves the intelligence level of the electricity stealing prevention alarm and avoids the defect of false alarm.
Description
Technical field [0001] The present invention relates to the field of electricity metering control, and in particular, to a remote anti-theft device and an anti-theft method. Background technique [0002] The problem of anti-stealing power is a long-standing management problem for the power management department. The existing intelligent anti-stealing technologies can be summarized into two categories: [0003] One type is the internal anti-stealing technology of the electric meter. This technology mainly prevents illegal attacks on the electric meter from the outside world. In today's smart electric meters, they are all done relatively well. Even after the attack, the attacker still leaves something that is difficult to erase. Evidence; the second category is for anti-theft technologies outside the meter. The existing technical solution is: compare the sum of the electricity collected by each sub-meter with the electricity collected by the total meter, and subtract the total meter ...
