Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] see figure 1 , the present invention's anti-strong magnetic field electricity theft alarm method comprises the following steps:

[0017] a. Detect the magnetic field strength around the electric energy meter;

[0018] b. Judging whether the magnetic field strength around the electric energy meter exceeds the critical magnetic field strength, if so, it is regarded as an abnormal magnetic field, perform step c, if not, return to step a;

[0019] c. Monitor whether the duration of the abnormal magnetic field reaches the critical time, if so, it will be regarded as a hidden danger of electricity stealing, and step d will be executed, if not, return to step a;

[0020] d. Send an alarm signal to the staff and record the number of times the alarm signal is sent;

[0021] e. Monitor whether the reply signal is received within the set time after the alarm signal is sent o...

Abstract

An alarm method for preventing power theft through a strong magnetic field comprises the following steps: a. detecting the magnetic field strength around an electric energy meter; b, judging whether the magnetic field strength around the electric energy meter exceeds critical magnetic field strength, and determining that an abnormal magnetic field occurs if the magnetic field strength around the electric energy meter exceeds the critical magnetic field strength; c, monitoring whether the duration of the abnormal magnetic field reaches critical time, and determining that there is hidden danger of power theft if the duration of the abnormal magnetic field reaches the critical time; d, sending an alarm signal to a worker, and recording the number of sending times of the alarm signal; and e, monitoring whether a response signal is received within set time after the alarm signal is sent and judging whether the number of sending times of the alarm signal reaches a set number of times, returning to step d under the condition that the number of sending times of the alarm signal does not reach the set number of times if no response signal is received, sending an alarm signal to a backend server if the number of sending times of the alarm signal reaches the set number of times, and then ending the process and automatically going to next round of alarm standby state. The method of the invention can be implemented in a fully automatic way, and is high in accuracy. By adopting the method, the hidden danger of power theft can be found the first time.

Description

technical field [0001] The invention relates to the field of electricity inspection, in particular to an anti-strong magnetic field electricity theft alarm method. Background technique [0002] With the development of social economy and the increase of electricity consumption, the problem of electricity theft has become more and more prominent in the society. At present, the common way of electricity theft is to cause the measurement failure of the electric energy meter through the strong magnetic field and thus steal the electricity. [0003] The currently used strong magnetic field stealing alarm method is as follows: through the marketing system, high-loss lines and station areas are screened out, and then the relevant users of lines and station areas with abnormal line loss are checked one by one. The above method is not only time-consuming and labor-intensive, but also adds a lot of workload to the electric inspection staff, and it cannot be discovered in the early stag...
