Problems solved by technology
[0004] However, the detection method described above has the following disadvantages: due to its own material and structural design, long-term use of the tact switch is likely to cause problems such as device damage, such as oxidation of metal parts, spring failure, and aging of plastic parts. The above problems may The failure of the device itself will cause the smart meter to open the cover and record abnormally; at the same time, it will also lead to false triggering of the record when the body of the smart meter vibrates or the surface is impacted by external forces due to the problem of matching the light touch button with the meter cover.

Embodiment Construction
[0041] In order to make the above objects, features and advantages of the present application more clearly understood, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings and specific implementation manners.
[0042] see figure 1 , which is a schematic diagram of a smart meter provided by an embodiment of the present application.
[0043] The smart meter provided by this embodiment includes: a meter cover 101, a measurement module 102, a wireless transceiver 103, and a controller 104;
[0044] The wireless transceiver 103 is arranged on the measurement module 102; since the measurement module 102 is arranged opposite to the watch cover 101, the wireless transceiver 103 is arranged opposite to the watch cover 101;
[0045] The measurement module 102 may be a circuit board, and some detection functions of the smart meter may be integrated on the measurement module 102 .
[0046] It should be understoo...

The invention discloses an intelligent electric meter and an electricity larceny prevention method. The intelligent electric meter comprises a measurement module, a wireless transceiver, a meter cover and a controller. The measuring module and the meter cover are oppositely arranged; the wireless transceiver is arranged on the measuring module; the wireless transceiver is used for sending a wireless signal to the meter cover and receiving a reflected wireless signal of the meter cover; the controller is used for obtaining a first distance between the meter cover and the wireless transceiver according to a first time when the wireless transceiver sends the wireless signal and a second time when the wireless transceiver receives the reflected wireless signal of the meter cover, and judging whether the meter cover is opened or not according to the first distance; or the controller is used for judging whether the meter cover is opened or not according to the time for waiting to reflect the wireless signal. Whether the distance between the wireless transceiver and the meter cover exceeds a set distance threshold value or not is judged according to the time difference of wireless signal sending and receiving, whether the meter cover is opened privately or not is judged, and an alarm is given in time after opening, so that electricity stealing is prevented. According to the scheme, the safety is high, and misjudgment caused by accidental touch is avoided.
Description
technical field [0001] The present application relates to the technical field of power equipment, and in particular, to a smart meter and a method for preventing electricity theft. Background technique [0002] With the development of science and technology, electric meters are becoming more and more intelligent, and remote meter reading and remote control can be realized. The smart meter includes a cover, which can only be opened by staff under normal circumstances. If the user opens the cover without permission, there may be a risk of electricity theft. Therefore, it is necessary to monitor whether the user has opened the watch cover without permission. [0003] At present, one way to monitor the user's opening of the smart meter cover is to install a tact switch on the measurement module of the smart meter, and to monitor whether the meter cover is opened by the user by judging the different states of the tact switch and the meter cover. [0004] However, the detection ...
