[0043] Please refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the present invention provides a strong magnetic control device for detecting an energy controller of an electric meter, and a magnet 1 for controlling the energy controller of the electric meter to perform strong magnetic detection, comprising: a fixing component 2, a driving component 3, a control component and a shielding component 4; one end of the fixing component 2 is detachably connected to the magnet 1, and the other end thereof is rotatably connected to the driving component 3; the driving component 3 is electrically connected to the control component; the shielding component 4 is provided with a groove, and the groove matches the shape of the magnet 1; the control component controls the driving component 3 to drive the fixing component 2 to rotate horizontally according to an external strong magnetic detection control signal, so that the magnet 1 moves into or out of the groove of the shielding component 4.

[0044] After the detection system is started, the above-mentioned strong magnetic control device can realize the automatic displacement of the magnet 1 through the driving component 3 according to the control instructions of the detection system during the strong magnetic detection process of the electric meter energy controller, and realize the magnetic field shielding of the magnet 1 after the detection is completed through the shielding component 4, thereby reducing the interference with other devices of the detection system and improving the detection accuracy.

[0045] Specifically, the driving assembly 3 includes: a motor 31, a worm gear and a rotating platform 32. The motor 31 is electrically connected to the control assembly, and its output shaft is fixedly connected to the worm gear; the worm gear is rotationally connected to the worm gear; the motor 31 drives the rotating platform 32 to rotate horizontally through the worm gear, thereby driving the fixed assembly 2 and the magnet 1 to rotate horizontally.
