[0002] With the rapid development of my country's economy, the electricity consumption of society is also growing. However, some electricity users, driven by profit, use electricity theft as a means of profit, and do not hesitate to use various illegal means to steal electricity, and the technology and methods of stealing electricity are becoming more and more high-tech. The act of stealing electricity not only threatens the legitimate interests of power supply companies and disrupts the daily power supply order, but also seriously endangers the normal operation of the social and economic order.

[0003] In the prior art, power inspectors check whether users are stealing electricity by checking each line in the user's electricity meter one by one. This is inefficient and requires a lot of manpower. At the same time, there is a possibility that the power inspectors will make false detections or miss detections. Summary of the invention

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0023] Embodiment 1

[0024] Figure 1 This is a schematic diagram of the structure of a user power consumption monitoring system provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where real-time monitoring of user power consumption is performed, such as Figure 1 As shown, the system includes: a first information collection device 100, a second information collection device 200 and an information processing device 300;

[0025] Among them, the first information collection device 100 is used to collect the actual power consumption information of the electric meter of each target user; the second information collection device 200 is used to collect the displayed power information on the electric meter of each target user; the information processing device 300 is electrically connected to the first information collection device 100 and the second information collection device 200, respectively, and is used to calculate the first difference between the displayed power information and the actual power consumption information. If the first difference is greater than the first preset difference threshold, it is determined that there is an abnormality in the power consumption of the target user.

[0026] Exemplarily, the first information collection device may be a device for collecting actual power consumption information of electric meters of each target user. For example, it may be a concentrator. Figure 2 The connection diagram of the first information collection device and the electric meter of each target user, the first information collection device (concentrator) and the electric meter of each target user can be connected through a communication bus, specifically, can be connected through an RS485 bus.

[0027] It should be noted that, in addition to the RS485 bus communication method, the connection method between the above-mentioned concentrator and each target electric meter can also be connected through a carrier communication module, a micro-power wireless module, a wireless public network module, and an optical fiber private network module. The specific connection method between the concentrator and the electric meter of each target user can be set according to user needs and is not limited here.

[0028] It should be noted that in Figure 2 There are two concentrators in the figure, each of which collects the actual power consumption information of the electric meters of six target users. However, in actual applications, it is not necessarily based on Figure 2 In actual applications, the number of concentrators and the number of target users' electricity meters collected by the concentrators can be set according to user needs, and there is no limitation here. That is, there can be only one concentrator here, which is used to collect the actual power consumption information of all target users' electricity meters.

[0029] The target user may be a user who wants to collect the actual power consumption information of the electric meter.

[0030] The actual power consumption information may be the actual power consumption information of the target user's power meter collected by the concentrator.

[0031] The second information collection device may be a device for collecting the displayed power information displayed on the electric meter of each target user. For example, the second information collection device here may collect the displayed power information displayed on the electric meter of each target user using an electric meter tester based on an infrared communication module.

[0032] The displayed power information here may be the power consumption information of the target user directly displayed by the display unit on the power meter of the target user.

[0033] Because in actual applications, if a user steals electricity, the power information displayed on his meter will be inconsistent with the actual power consumption information. Therefore, it is necessary to collect the displayed power information and actual power consumption information of the target user, and compare the two to determine whether the target user has stolen electricity.

[0034] The information processing device may be a device for processing information data, for example, a processor or the like.

[0035] The first difference may be a calculated difference between the collected displayed power consumption information of the target user and the actual power consumption information thereof.

[0036] The first preset difference threshold may be a pre-set first difference threshold. When the first difference is greater than the threshold, it indicates that the actual power consumption information of the target user is inconsistent with the displayed power information displayed on the electric meter, indicating that the power consumption of the target user may be abnormal.

[0037] It should be noted that when collecting the displayed power information and actual power consumption information of each target user, the collected data may be active power, reactive power, maximum forward active power demand, forward power metering information and reverse power metering information, etc.

[0038] In this way, by calculating the difference between the displayed power information and the actual power consumption information of the collected target user, it is possible to determine whether the actual power consumption information of the target user is accurate, thereby achieving real-time monitoring of the power information of the target user and preventing the target user from stealing electricity.

[0039] The technical solution of the embodiment of the present invention designs a user electricity consumption monitoring system, which includes: a first information collection device, a second information collection device and an information processing device, wherein the actual power consumption information of each target user is collected based on the first information collection device, and the displayed power information of each target user is collected based on the second information collection device. The information processing device calculates the difference between the displayed power information and the actual power consumption information of the target user. Based on the difference, it can be determined whether the actual power consumption information of the target user is accurate, thereby realizing real-time monitoring of the power information of the target user and preventing the target user from stealing electricity.

[0040] Embodiment 2

[0041] Figure 3 This is a schematic diagram of the structure of the user electricity monitoring system provided in the second embodiment of the present invention. The embodiment of the present invention can be combined with each optional solution in the above embodiment. In the embodiment of the present invention, optionally, the system further includes: a first signal detection device 400 electrically connected to the electric meter;

[0042] Optionally, the first signal detection device 400 is used to collect the first signal from the electric meter of each target user and send the first signal to the information processing device 300; the information processing device 300 is used to receive the first signal and the second signal on each electric meter collected by the sensor in the electric meter of each target user, calculate the second difference between the first signal and the second signal, and if the second difference is greater than a second preset difference threshold, it is determined that there is an abnormality in the electric power of the target user.

[0043] Exemplarily, the first signal detection device may be a device for collecting signals from the electric meter of each target user, where the signal may be, for example, a voltage signal and / or a current signal. The first signal detection device may be, for example, a detection CT. The first signal detection device may be arranged at the incoming line side of the electric meter of each target user.

[0044] The first signal may be a current signal and / or a voltage signal of an electric meter of each target user detected by the first signal detection device.

[0045] The second signal may be a current signal and / or a voltage signal of the electric meter of each target user collected by a sensor built into the electric meter of the target user.

[0046] The second difference may be a difference between the first signal and the second signal.

[0047] The second preset difference threshold may be a pre-set second difference threshold. When the second difference is less than or equal to the threshold, it indicates that the target user's electric meter has no faults. The actual power consumption information of the target user is inconsistent with the displayed power information on the electric meter due to abnormal power consumption of the target user. This indicates that the target user's power consumption may be abnormal.

[0048] It should be noted that the first signal collected here may also be the first signal collected only from the electric meter of the target user whose first difference determined in the above embodiment is greater than the first preset difference threshold; correspondingly, the second signal here may also be the second signal collected only from the electric meter of the target user whose first difference determined in the above embodiment is greater than the first preset difference threshold. In this way, it is only necessary to obtain the signal of the electric meter of the target user whose first difference is greater than the first preset difference threshold, and it is not necessary to obtain the signals of the electric meters of all target users, which saves time and improves detection efficiency.

[0049] In order to avoid the calculated first difference being greater than the first preset difference threshold value due to a fault in the electric meter itself, that is, the electric meter itself may be faulty, so the collected electric meter's displayed power information will have errors, which will cause the first difference to be greater than the first preset difference threshold value, resulting in the detection of the target user's power consumption being abnormal, but in fact the target user's power consumption is not abnormal, therefore, it is necessary to exclude the fault factor of the electric meter itself, so according to the difference between the first signal and the second signal collected from the electric meter, determine whether the electric meter is faulty. If the second difference between the first signal and the second signal is less than or equal to the second preset difference threshold value, it means that the electric meter is not faulty, so it is determined that the first difference being greater than the first preset difference threshold value is caused by the target user's power consumption being abnormal.

[0050] This avoids misjudgment caused by failure of the meter's sensor and improves the accuracy of determining whether the target user's electricity consumption is abnormal.

[0051] refer to Figure 4 A schematic diagram of information processing execution of the information processing device, Figure 4 Step 11-step 13 in the figure are steps for information processing performed by the information processing device in the first embodiment. Figure 4 Step 14-step 17 in the figure are steps for information processing performed by the information processing device in the second embodiment of the present invention.

[0052] The technical solution of the embodiment of the present invention is to design a first signal detection device to collect the first signal of each target user's electric meter and send the first signal to the information processing device; the information processing device receives the first signal and the second signal on each electric meter collected by the sensor in the electric meter of each target user, calculates the second difference between the first signal and the second signal, and if the second difference is greater than the second preset difference threshold, it is determined that the target user's electric power is abnormal. This avoids the misjudgment caused by the failure of the electric meter sensor and improves the accuracy of judging whether the target user's electricity consumption is abnormal.

[0053] Embodiment 3

[0054] Figure 5 This is a schematic diagram of the structure of the user power consumption monitoring system provided in the third embodiment of the present invention. The embodiment of the present invention can be combined with each optional solution in the above embodiment. In the embodiment of the present invention, optionally, the system further includes: a third information collection device 500 electrically connected to the information processing device;

[0055] Optionally, a third information collection device 500 is used to collect the sum of actual electricity consumption information of each target user, and send the sum of actual electricity consumption information to the information processing device 300; the information processing device 300 is used to determine the sum of actual electricity consumption information of each target user based on the actual electricity consumption information of the electricity meter of each target user; calculate the third difference between the sum of actual electricity consumption information and the sum of actual electricity consumption information, and if the third difference is greater than a third preset difference threshold, it is determined that there is an abnormality in the electricity consumption of each target user.

[0056] Exemplarily, the third information collection device may be a device for collecting the total actual power consumption information of each target user, for example, a gateway meter set at the transformer end.

[0057] The sum of actual power consumption information may be the sum of actual power consumption information of all target users.

[0058] The information processing device obtains the sum of the actual power consumption information of each target user based on the actual power consumption information of the electric meter of each target user collected by the above-mentioned first information collection device, that is, obtains the sum of the actual power consumption information of all target users obtained based on the first information collection device.

[0059] The third difference may be a difference between the sum of the actual power usage information and the sum of the actual power consumption information.

[0060] The third preset difference threshold may be a pre-set third difference threshold. When the third difference is greater than the threshold, it indicates that the sum of the actual power consumption information of all target users collected by the gateway meter does not match the sum of the actual power consumption information obtained through the actual power consumption information collected through the first information, indicating that the power consumption of the target user may be abnormal.

[0061] The information processing device calculates the difference between the sum of the actual power usage information and the sum of the actual power consumption information based on the sum of the actual power usage information obtained above and the sum of the actual power consumption information. When the difference between the sum of the actual power usage information and the sum of the actual power consumption information is greater than the third preset difference threshold, it indicates that the power usage of the target user may be abnormal. Figure 4 Step 1-step 3 in the figure are steps for information processing performed by the information processing device in the third embodiment of the present invention.

[0062] In this way, the total power consumption information of all target users can be calculated to determine whether there is any abnormal power consumption of the target user. If the total power consumption information of all target users is calculated and no abnormal power consumption of the target user is determined, there is no need to perform the subsequent step of calculating the power consumption information of a certain target user, that is, there is no need to perform the step of information processing by the information processing device in the above-mentioned embodiment 1 and embodiment 2. This saves time and improves detection efficiency.

[0063] The technical solution of the embodiment of the present invention obtains the sum of actual power consumption information of each target user by designing a third information collection device. The information processing device determines the sum of actual power consumption information of each target user based on the actual power consumption information of the electric meter of each target user; calculates the third difference between the sum of actual power consumption information and the sum of actual power consumption information. If the third difference is greater than the third preset difference threshold, it is determined that the power consumption of each target user is abnormal. In this way, the total power consumption information of all target users can be calculated first to determine whether there is an abnormality in the power consumption of any target user. If there is no abnormality, there is no need to perform the subsequent step of calculating the power consumption information of a certain target user, which saves time and improves detection efficiency.

[0064] Embodiment 4

[0065] Figure 6 This is a schematic diagram of the structure of the user power consumption monitoring system provided in the fourth embodiment of the present invention. The embodiment of the present invention can be combined with each optional solution in the above embodiment. In the embodiment of the present invention, optionally, the system further includes: a second signal detection device 600 electrically connected to the first information collection device;

[0066] Optionally, the second signal detection device 600 is used to collect the third signal of the first information collection device 100 and send the third signal to the information processing device 300; the information processing device 300 is used to receive the third signal and the fourth signal on the first information collection device 100 collected by the sensor in the first information collection device 100, calculate the fourth difference between the third signal and the fourth signal, and if the fourth difference is greater than a fourth preset difference threshold, it is determined that there is an abnormality in the power level of the target user.

[0067] Exemplarily, the second signal detection device may be a device for collecting signals from the first information collection device, where the signals may be, for example, voltage signals and / or current signals, etc. The second signal detection device may be, for example, a detection CT. The second signal detection device may be arranged at the incoming line side of the second information collection device (concentrator).

[0068] The third signal may be a current signal and / or a voltage signal of the first information acquisition device detected by the second signal detection device.

[0069] The fourth signal may be a current signal and / or a voltage signal of the first information acquisition device acquired by a sensor built into the first information acquisition device.

[0070] The fourth difference may be a difference between the third signal and the fourth signal.

[0071] The fourth preset difference threshold may be a preset fourth difference threshold. When the fourth difference is greater than the threshold, it indicates that the first information collection device may be faulty.

[0072] In order to avoid the situation where the calculated third difference is greater than the third preset difference threshold due to a fault in the electric meter itself, that is, the first information collection device (concentrator) itself may be faulty, so the actual power consumption information collected by the electric meter will be erroneous, which will cause the third difference to be greater than the third preset difference threshold, resulting in the detection of possible abnormalities in the target user's electricity consumption, but in fact the target user's electricity consumption is not abnormal. Therefore, it is necessary to exclude the fault factor of the first information collection device itself. Therefore, the difference between the third signal and the fourth signal collected by the first information collection device is used to determine whether the first information collection device is faulty. If the fourth difference between the third signal and the fourth signal is greater than the fourth preset difference threshold, it means that the first information collection device is faulty, and then the execution Figure 4 If the fourth difference between the third signal and the fourth signal is less than the fourth preset difference threshold, it is determined that the third difference is greater than the third preset difference threshold because one or several target users among all target users have abnormal power consumption.

[0073] It should be noted that the process of the above-mentioned information processing device processing the fourth signal and the third signal is as follows: Figure 4 Follow the steps from step 4 to step 6 in the above code.

[0074] This avoids misjudgment caused by failure of the sensor of the first information collection device and improves the accuracy of determining whether the target user's electricity consumption is abnormal.

[0075] Optional, such as Figure 4 As shown in step 7-step 10, after determining that the fourth difference is greater than the fourth preset difference threshold, the information processing device 300 is also used to: calculate the sum of the power consumption information of each target user collected by the first information collection device 100 based on the third signal to obtain the sum of the power consumption information; replace the sum of the actual power consumption information with the sum of the power consumption information, and recalculate the fifth difference between the sum of the power consumption information and the sum of the actual power consumption information; if the fifth difference is greater than the fifth preset difference threshold, it is determined that there is an abnormality in the power consumption of each target user.

[0076] Exemplarily, the sum of the power consumption information can be obtained based on the third signal collected by the first information collection device. For example, the third signal here is a current signal and a voltage signal. Then, based on the current signal and the voltage signal collected by the first information collection device, according to the formula P=UI, the power consumption information of each target user that should be collected by the first information collection can be obtained. Based on the power consumption information of each target user actually collected, the sum of the power consumption information of all target users actually collected can be obtained.

[0077] The sum of the power consumption information obtained above is used to replace the actual power consumption information of the power meters of each target user collected by the first information collection device, and the sum of the actual power consumption information of the power meters of all target users is obtained. The difference between the sum of the actual power consumption information after replacement and the sum of the actual power consumption information of all target users collected by the third information collection device is calculated, and the difference is compared with the third preset difference threshold. If the difference is greater than the third preset difference threshold, step 11 is executed.

[0078] In this way, if the first information collection device fails, it can also be determined whether there is an abnormality in the target user's electricity consumption, thereby ensuring normal monitoring of the target user's electricity consumption information and preventing electricity theft.

[0079] The technical solution of the embodiment of the present invention is to design a second signal detection device to collect the third signal of the first information collection device; the information processing device receives the third signal and the fourth signal on the first information collection device collected by the sensor in the first information collection device, calculates the fourth difference between the third signal and the fourth signal, and if the fourth difference is greater than the fourth preset difference threshold, it is determined that the power of the target user is abnormal, thereby avoiding the misjudgment caused by the failure of the sensor of the first information collection device, and improving the accuracy of judging whether the power consumption of the target user is abnormal. At the same time, the information processing device is also used to: based on the third signal, calculate the sum of the power consumption information of each target user collected by the first information collection device to obtain the sum of power consumption information; replace the sum of the actual power consumption information with the sum of the power consumption information, and recalculate the fifth difference between the sum of the power consumption information and the sum of the actual power consumption information, and if the fifth difference is greater than the fifth preset difference threshold, it is determined that the power of each target user is abnormal, so that if the first information collection device fails, it can also be determined whether the power consumption of the target user is abnormal, ensuring the normal monitoring of the power consumption information of the target user and preventing the effect of power theft.

[0080] Embodiment 5

[0081] Figure 7This is a schematic diagram of the structure of the user power consumption monitoring system provided in Embodiment 5 of the present invention. The embodiment of the present invention can be combined with each optional solution in the above embodiments. In the embodiment of the present invention, optionally, the system further includes: an alarm device 700 and a display device 800 electrically connected to the information processing device 300;

[0082] Optionally, both the actual power consumption information and the displayed power information include user identification information of the corresponding target users.

[0083] Exemplarily, the user identification information of a target user may be information used to represent the target user, for example, may be attribute information of the target user, such as name, number or telephone number.

[0084] Optionally, the information processing device 300 is used to send the user identification information of the target user with abnormal power to the alarm device 700; the alarm device 700 is used to generate alarm information corresponding to the target user with abnormal power.

[0085] Exemplarily, the alarm device may be any device that can be used for alarm.

[0086] When the information processing device determines that a target user has abnormal power consumption, the user identification information of the target user with abnormal power consumption is sent to the alarm device, and the alarm device generates alarm information of the target user with abnormal power consumption according to the user identification information.

[0087] The alarm device can also generate an alarm sound to remind electricity usage inspection personnel that there are target users with abnormal electricity consumption, so that electricity usage inspection personnel can determine the target users with abnormal electricity consumption based on the user identification information, conduct on-site inspections on the target users' electricity consumption, and determine whether the target users are stealing electricity.

[0088] Optionally, the information processing device 300 is used to send the user identification information of the target user with abnormal power to the display device 800; the display device 800 is used to display the user identification information of the target user with abnormal power.

[0089] Exemplarily, the display device may be a device for displaying information, such as a display.

[0090] When the information processing device determines that a target user has abnormal electricity consumption, the user identification information of the target user with abnormal electricity consumption is sent to the display device. The display device may display the user identification information of the target user with abnormal electricity consumption to prompt electricity usage inspection personnel that there is a target user with abnormal electricity consumption, so that the electricity usage inspection personnel can determine the target user with abnormal electricity consumption based on the user identification information, conduct an on-site inspection of the target user's electricity consumption, and determine whether the target user has stolen electricity.

[0091] In this way, the target users with abnormal electricity consumption can be known intuitively and vividly, so that the electricity detection personnel can check the target users with abnormal electricity consumption according to the user identification information of the target users and determine whether the target users have stolen electricity, thereby achieving the effect of real-time monitoring of the target users' electricity consumption and avoiding electricity theft.

[0092] The technical solution of the embodiment of the present invention is to design an alarm device and a display device, wherein an information processing device sends user identification information of a target user with abnormal power consumption to the alarm device and the display device, so that the alarm device generates alarm information corresponding to the target user with abnormal power consumption, and the display device displays the user identification information of the target user with abnormal power consumption. In this way, the target user with abnormal power consumption can be known intuitively and vividly, so that power detection personnel can check the target user with abnormal power consumption according to the user identification information of the target user to determine whether the target user has stolen electricity, thereby achieving the effect of real-time monitoring of the target user's power consumption and avoiding electricity theft.
