Novel electric energy meter

Abstract

The invention relates to a novel electric energy meter which comprises the components of a sampling module which acquires current and voltage information of commercial power transmission; a metering module which is connected with the output end of the sampling module and performs conversion output on the current and voltage information; a control module which is connected with the metering moduleand receives an output signal of the metering module and performs bidirectional communication with the metering module; a display module which is connected with the control module and performs data displaying according to the signal that is output from the control module; and a power supply module which is used for supplying electric energy to each module. The novel electric energy meter is characterized by comprising a magnetic detecting module which is connected with the control module and is used for detecting a magnetic field signal around the electric energy meter, and transmitting detecting information to the control module; and an output module which is connected with the control module and performs alarming according to the output signal of the control module. Compared with prior art, the novel electric energy meter provided by the invention has advantages of detecting magnetic field strength around the electric energy meter, preventing electric energy theft, realizing more reasonable design and obtaining higher user-friendly performance.

Description

technical field [0001] The invention relates to the field of electric energy meter counting, in particular to a novel electric energy meter. Background technique [0002] The electric energy meter is a conventional household device, which is used to measure the electricity consumption of users. However, driven by interests, a very small number of unscrupulous citizens often tamper with the electric energy meter, hindering the normal operation of the electric energy meter, making it count less or not. cause extremely adverse effects. [0003] In order to stop the generation of this kind of phenomenon, the power supply department tries to install the electric energy meter in the anti-theft electric meter box, and installs the alarm outside the electric meter box, but this kind of method can not play good effect.

[0002] The electric energy meter is a conventional household device, which is used to measure the electricity consumption of users. However, driven by interests, a very small number of unscrupulous citizens often tamper with the electric energy meter, hindering the normal operation of the electric energy meter, making it count less or not. have an extremely adverse effect on

[0003] In order to prevent this phenomenon from happening, the power supply department tried to install the electric energy meter in the anti-theft electric meter box, and installed an alarm outside the electric meter box, but this method did not play a very good role.

Because most of the existing electric energy meters are electronic electric energy meters, most of their internal parts are electromagnetic components, which are easily disturbed by electromagnetic fields. When there is a large magnetic field interference nearby, the internal devices will be affected, such as detection sensitivity and measurement accuracy. etc. are greatly reduced, and unscrupulous citizens often seize this defect and place magnet blocks in hidden positions in the anti-theft meter box to affect the degree of the meter.

[0004] And when reading the meter, the staff need to be close to the electric energy meter to know the data. If the position of the electric energy meter is relatively narrow, it will bring certain difficulties to the staff, which is not conducive to carrying out work; at the same time, the existing electric energy The structure and functions of the watch have been fixed before leaving the factory. Users cannot choose and match the corresponding functions according to their own needs. The design is not reasonable enough.
