The specific analysis process is as follows: Analyze the electricity consumption time period i to obtain the season and date category of the electricity consumption time period, where the season includes Spring Festival, summer, autumn and winter; the date category includes working days (generally Monday to Friday), holidays and rest days (generally Saturday and Sunday); Obtain the historical power consumption of the smart meter for the power consumption time period i corresponding to the season and date category, and use it as a historical power consumption sample, and count the amount of power consumption in the sample. If the amount is less than the set sample quantity threshold, directly select the power consumption of the adjacent days before the power consumption time period as the historical power consumption sample. The adjacent days are selected from the latter to the former according to the time, and the selected number is equal to the difference between the sample quantity threshold and the amount of power consumption in the statistical sample; The historical electricity consumption in the historical electricity consumption sample is marked as Mj, j = 1, 2, ..., m; m represents the total amount of historical electricity consumption; Substitute into the formula Get the historical power anomaly value MLi of power consumption time period i; Select the largest historical electricity consumption in the historical electricity consumption sample and mark it as Mmax, calculate the mean of all historical electricity consumption in the historical electricity consumption sample and mark it as Mp, and substitute it into the formula Get the electrical anomaly value MYi, where ω1, ω2, and ω3 are all preset weight factors, and ω2>ω3>ω1>0; Decompose the power consumption time period i into several sub-periods, obtain the sub-power consumption corresponding to each sub-period, and sort the sub-power consumption according to the time sequence, calculate the difference between two adjacent sub-power consumptions, subtract the value of the sub-power consumption in the later order from the value of the sub-power consumption in the earlier order to obtain the sub-difference value, sum up all the sub-difference values ​​to obtain the total sub-difference value, and at the same time count the number of sub-power consumptions in the later order that are higher than the sub-power consumption in the earlier order and mark them as sub-high values; perform weighted calculation on the total sub-difference value and the sub-high value, multiply them by the corresponding weight factors respectively, and then sum them to obtain the historical power anomaly value three MKi; Input the values ​​of the anomaly value 1, the anomaly value 2 and the anomaly value 3 into the computer, then convert the values ​​into lengths according to a certain ratio, draw two parallel straight lines with the lengths of the anomaly value 1 and the anomaly value 2, then construct a trapezoid with the length of the anomaly value 3 as the height, calculate the area of ​​the trapezoid and mark the area value as the theft value; If the electricity theft value is greater than the set threshold value one and less than or equal to the set threshold value two, an electricity theft reminder instruction is generated and sent to the smart terminal of the corresponding manager of the smart meter, and then a reminder is issued. If the electricity theft value is greater than the set threshold value two, an electricity theft instruction is generated and the first motor 7 is started. At this time, the first motor 7 will drive the threaded shaft 8 to rotate. Because the threaded shaft 8 is threadedly connected to the insulating plate 9, the rotation of the threaded shaft 8 drives the insulating plate 9 to move up, and the insulating plate 9 drives the power connection plate 10 to move up. When the power connection plate 10 moves to a certain position, it will contact the first connection end 12 on the alarm device 11, so that electricity is transferred from the power connection plate 10 to the first connection end 12 and the alarm device 11. At this time, the alarm device 11 will alarm and remind the worker. If there is electricity theft by workers or users, the workers or users can check the smart meter in time, and when the power connection plate 10 moves up, it will cause the power connection plate 10 to be separated from the power output terminal 6, thereby cutting off the power at the power output terminal 6, so that when the user cannot hear the sound of the alarm device 11 at home, the power-off method can promptly remind the user that the smart meter has an abnormality, thereby making the reminder method of the present device more convenient to attract the user's attention, and because the present device is not a trigger alarm method, the present device will not alarm when the smart meter is turned on, thereby making the present device more intelligent and convenient, and the alarm device 11 is usually in a power-off state, and the alarm device 11 can only be energized when the power connection plate 10 moves up, so that the alarm device 11 in the present device can save electricity consumption.

When the device detects theft of electricity and causes the power connection plate 10 to move upward, the outer wall bottom end of the second connecting end 16 is flush with the outer wall bottom end of the first connecting end 12, so that the power connection plate 10 contacts the first connecting end 12. When the first connection end 12 is in contact with the second connection end 16, the second connection end 16 is energized. Since the second connection end 16 is electrically connected to the camera 15, the camera 15 is also energized. When the device detects an abnormality due to electricity theft, the camera 15 is activated to capture the situation outside the shell 1. When someone steals electricity, the camera 15 captures the electricity thief. The device can determine whether electricity has been stolen from the device through the image captured by the camera 15. This saves the time for staff or users to determine the cause of the abnormality of the smart meter, and allows staff to deal with the electricity theft more promptly.

[0019] The outer wall of the slider 14 is slidably connected to the inner wall of the square through groove 13; a second motor 17 is fixedly connected to one side of the inner wall of the shell 1; a reciprocating shaft 18 is provided at the output end of the second motor 17, and one end of the outer wall of the reciprocating shaft 18 passes through the slider 14, and the reciprocating shaft 18 is slidably connected to the slider 14; a third connection end 19 is fixedly connected to the other side of the outer wall of the alarm device 11 through a second connecting plate, and the bottom end of the outer wall of the third connection end 19 is flush with the bottom end of the outer wall of the first connection end 12, and the third connection end 19 is electrically connected to the second motor 17. When the device detects theft of electricity and causes the power connection plate 10 to move up, because the bottom end of the outer wall of the third connection end 19 is flush with the bottom end of the outer wall of the first connection end 12, the power connection plate 10 moves up to energize the first connection end 12. The end 19 will also be energized, because the third connection end 19 is electrically connected to the second motor 17, so that when the third connection end 19 is energized, the second motor 17 will also be energized, so that the second motor 17 drives the reciprocating shaft 18 to rotate, and the rotation of the reciprocating shaft 18 drives the slider 14 to reciprocate back and forth, and the reciprocating movement of the slider 14 will drive the camera 15 to reciprocate, so that when the device detects the electricity theft, the camera 15 will also move while shooting, thereby increasing the shooting range of the camera 15, so that the camera 15 has no blind spot for shooting, so that the electricity thief cannot avoid the camera 15 to steal electricity by shooting the blind spot, so that the anti-electricity theft function of the device is further improved, and it is also more difficult for the electricity thief to steal electricity, thereby reducing the probability of the smart meter being stolen.

[0020] Embodiment 2:

[0021] See also Figure 4-Figure 7 As shown, a transparent plate 20 is fixedly connected to one side of the outer wall of the sealing plate 3, and the transparent plate 20 matches the square through groove 13; wiping blocks 21 are fixedly connected to the opposite sides of the outer wall of the slider 14, and one side of the outer wall of a pair of wiping blocks 21 is in contact with one side of the outer wall of the transparent plate 20. When the slider 14 and the camera 15 move back and forth, the movement of the slider 14 will drive the movement of the pair of wiping blocks 21, so that the wiping blocks 21 wipe the transparent plate 20. Because the smart meter is placed in the meter box for a long time and will be contaminated with dust, the transparent plate 20 will make the picture taken by the camera 15 unclear when it is contaminated with dust. The dust on one side of the outer wall of the transparent plate 20 can be wiped by the wiping block 21, so that the picture of the camera 15 is clearer when shooting, so that the camera 15 is not easily unable to shoot normally due to dust.

[0023] The first square shells 25 are fixedly connected to the opposite sides of the outer wall of the fixed block 22, and the pair of first square shells 25 match the gap; the dustproof plates 26 are fixedly connected to the opposite sides of the inner walls of the pair of first square shells 25 through the second spring, and the outer side wall of the dustproof plate 26 is slidably connected to the inner side wall of the first square shell 25, and the dustproof plate 26 matches the gap. Because a gap is provided between the top of the outer wall of the transparent plate 20 and the top of the inner wall of the square through groove 13, dust can easily enter the shell 1 through the gap. The first square shells 25 are fixedly connected to the opposite sides of the outer wall of the fixed block 22, and the dustproof plates 26 are fixedly connected to the opposite sides of the inner walls of the pair of first square shells 25 through the second spring, so that the first square shell 25 and the dustproof plate 26 can block the gap, so that dust is not easy to enter the shell 1 through the gap, and the first square shell 25 and the dustproof plate 26 are connected by the second spring. , so that the dustproof shell can be retracted into the first square shell 25, so that the slider 14 drives the fixed block 22 to move, thereby driving the first square shell 25 and the dustproof plate 26 to move. When the dustproof plate 26 touches the meter box due to the sliding and movement of the fixed block 22, the dustproof plate 26 will retract into the first square shell 25, so that the slider 14 can move normally, and the first square shell 25 and the dustproof plate 26 have sufficient length to seal the gap, so that the device not only prevents electricity theft through the alarm device 11, but also determines the abnormal situation of the smart meter through the camera 15, and further reminds the user that the smart meter has an abnormality by powering off, so that the device can effectively prevent electricity theft, and when the meter box and the smart meter are opened at ordinary times, as long as the line is not moved, just observation and inspection will not cause the alarm device 11 to sound.

[0024] When the present invention is in use, when the anti-electricity theft module in the meter body 2 detects that electricity is being stolen, the first motor 7 is started. At this time, the first motor 7 will drive the threaded shaft 8 to rotate. Because the threaded shaft 8 is threadedly connected to the insulating plate 9, the rotation of the threaded shaft 8 drives the insulating plate 9 to move upward, and the insulating plate 9 drives the power connection plate 10 to move upward. When the power connection plate 10 moves to a certain position, it will contact the first connection end 12 on the alarm device 11. At this time, electricity will be transmitted from the meter body 2 and the power connection plate 10 to the first connection end 12 and the alarm device 11. At this time, the alarm device 11 will alarm to remind the staff and users that someone has stolen electricity, so that the staff or users can check the smart meter in time, and when the power connection plate 10 moves upward, it will cause electricity The power connection plate 10 is separated from the power output terminal 6, so that the power output terminal 6 is powered off, so that when the user cannot hear the sound of the alarm device 11 at home, the power-off mode can timely remind the user that the smart meter has an abnormality, making the reminder mode of the device easier to attract the user's attention, and because the device is not a trigger alarm mode, the device will not alarm when the smart meter is turned on, making the device more intelligent and convenient, and when the device detects theft of electricity and moves the power connection plate 10 upward, because the outer wall bottom end of the second connection end 16 is flush with the outer wall bottom end of the first connection end 12, when the power connection plate 10 contacts the first connection end 12, it will also contact the second connection end 16 at the same time, so that the second connection end 16 is energized, and because the second connection end 16 is connected to the camera 1 5 is electrically connected, so that the camera 15 is also powered on and running, so that when the device detects an abnormality due to electricity theft, the camera 15 is started to shoot the situation outside the shell 1, so that when someone steals electricity, the camera 15 will shoot the electricity thief, so that the device can judge whether the device has been stolen by the picture taken by the camera 15, so that the staff or users can more conveniently judge the cause of the abnormality of the smart meter, and the staff can deal with the electricity theft more promptly, and when the device detects the electricity theft and moves the power connection plate 10 upward, because the outer wall bottom end of the third connection end 19 is flush with the outer wall bottom end of the first connection end 12, when the power connection plate 10 is moved upward to make the first connection end 12 powered, the third connection end 19 will also be powered, so that the third connection end 19 can be powered. The connection end 19 is electrically connected to the second motor 17, so that when the third connection end 19 is energized, the second motor 17 is also energized, so that the second motor 17 drives the reciprocating shaft 18 to rotate, and the rotation of the reciprocating shaft 18 drives the slider 14 to reciprocate back and forth, so that the reciprocating movement of the slider 14 drives the camera 15 to reciprocate, so that when the device detects the electricity theft, the camera 15 will also reciprocate while shooting, thereby increasing the shooting range of the camera 15, so that the camera 15 has no blind spots, so that the electricity thief cannot avoid the camera 15 to steal electricity by shooting blind spots, so that the anti-electricity theft effect of the device is further improved, and it is also more difficult for the electricity thief to steal electricity, thereby reducing the probability of the device being stolen.Because the alarm device 11, the camera 15 and the second motor 17 in the device are all in a power-off state at ordinary times, the device can save energy, and when the slider 14 and the camera 15 move back and forth, the movement of the slider 14 will drive the pair of wiping blocks 21 to move, and the movement of the slider 14 will also drive the fixed block 22, the movement of the fixed block 22 will drive the square shell 23 to move, and the movement of the square shell 23 will drive the cleaning block 24 to move, so that the cleaning block 24 cooperates with the wiping block 21 to wipe the entire transparent plate 20 where it needs to be wiped clean, because the smart meter is placed in the meter box for a long time and will be contaminated with dust, making the transparent When the plate 20 is stained with dust, the image captured by the camera 15 will be unclear. The wiping block 21 and the cleaning block 24 can be used to wipe the dust off the transparent plate 20, so that the image of the camera 15 is clearer when shooting, and the camera 15 is not easily unable to shoot normally due to dust. The cleaning cloth is fixed to the opposite side of the outer wall of the cleaning block 24 and the wiping block 21. Because the cleaning cloth is relatively soft, when the cleaning cloth wipes the transparent plate 20, it is not easy to scratch the transparent plate 20 and it is also easier to clean the dust. Moreover, because the cleaning block 24 is attached to the transparent plate 20 by the elastic force of the first spring, the cleaning block 24 is attached to the transparent plate 20 by the elastic force of the first spring. The cleaning block 24 is attached to the transparent plate 20 by the elastic force of the first spring when the cleaning block 24 moves under the action of an external force.

The first square shell 25 and the dustproof plates 26 are connected by the second spring, so that the dustproof shell can be retracted into the first square shell 25, so that the slider 14 drives the fixing block 22 to move, thereby driving the first square shell 25 to move. When the first square shell 25 and the dustproof plate 26 move, when the dustproof plate 26 touches the meter box due to the movement of the sliding and fixed block 22, the dustproof plate 26 will shrink into the first square shell 25, so that the slider 14 can move normally, and the first square shell 25 and the dustproof plate 26 have enough length to block the gap.
