Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural diagram of a user electricity consumption monitoring system according to a first embodiment of the present invention, where the present embodiment is applicable to a situation of monitoring electricity consumption of a user in real time, and as shown in fig. 1, the system includes: a first information collecting apparatus 100, a second information collecting apparatus 200, and an information processing apparatus 300;
the first information acquisition device 100 is configured to acquire actual power consumption information of the electric meters of the target users; the second information acquisition device 200 is used for acquiring the displayed electric quantity information on the electric meter of each target user; and the information processing device 300 is electrically connected with the first information acquisition device 100 and the second information acquisition device 200 respectively, and is configured to calculate a first difference between the displayed power information and the actually consumed power information, and determine that the power of the target user is abnormal if the first difference is greater than a first preset difference threshold.
For example, the first information collecting device may be a device for collecting information on an actual amount of power consumed by the electricity meter of each target user. For example, it may be a concentrator. Referring to fig. 2, a schematic diagram of the connection between the first information acquisition device and the electric meters of the target users is shown, where the first information acquisition device (concentrator) and the electric meters of the target users may be connected through a communication bus, and specifically, may be connected through an RS485 bus.
It should be noted that, the connection mode between the concentrator and each target electric meter may be, in addition to the RS485 bus communication mode, a carrier communication module, a micro-power wireless module, a wireless public network module, and an optical fiber private network module. The specific connection mode between the concentrator and the electric meters of the target users can be set according to the user requirements, and is not limited here.
It should be noted that 2 concentrators are shown in fig. 2, and each concentrator collects information about the actual power consumption of the electric meters of 6 target users, but in practical applications, the configuration shown in fig. 2 is not necessarily adopted. In practical applications, the number of the concentrators and the number of the electric meters of the target users collected by the concentrators may be set according to user requirements, and are not limited herein. That is, there may be only one concentrator for collecting the information of the actual power consumption of all the target users.
The target user may be a user who is to collect information on the amount of electricity actually consumed by the electricity meter.
The actually consumed power information may be power information actually consumed by the electric meter of the target user collected by the concentrator.
The second information collecting device may be a device for collecting display power amount information displayed on the electricity meters of the respective target users. For example, the second information collecting device may collect, by using the meter tester, information on the display power amount displayed on the electric meter of each target user based on the infrared communication module.
The displayed power information may be the power consumption information of the target user directly displayed by the display unit on the power meter of the target user.
In practical application, if the user steals electricity, the displayed electric quantity information on the electric meter is inconsistent with the actually consumed electric quantity information, so that the displayed electric quantity information and the actually consumed electric quantity information of the target user need to be collected and compared, and whether the target user has electricity stealing behavior can be determined.
The information processing apparatus may be an apparatus for processing information data, and may be, for example, a processor or the like.
The first difference value may be a difference value between the collected display power amount information of the target user and its actual consumption power amount information calculated.
The first preset difference threshold may be a preset first difference threshold, and when the first difference is greater than the threshold, it indicates that the actual consumed power information of the target user is not consistent with the display power information displayed on the electricity meter, and it indicates that there may be an abnormality in the power consumption of the target user.
It should be noted that, when the display electric quantity information and the actual consumption electric quantity information of each target user are collected, the collected data may be active power, reactive power, forward active maximum demand, forward electric energy metering information, reverse electric energy metering information, and the like.
Therefore, whether the actual electricity consumption and quantity information of the target user is accurate or not can be determined by calculating the difference value between the acquired display quantity information and the actual consumed quantity information of the target user, the real-time monitoring on the quantity information of the target user is realized, and the effect of preventing the target user from stealing electricity is achieved.
The technical scheme of the embodiment of the invention designs a user electricity utilization monitoring system, which comprises: the system comprises a first information acquisition device, a second information acquisition device and an information processing device, wherein the actual power consumption information of each target user is acquired based on the first information acquisition device, the display power information of each target user is acquired based on the second information acquisition device, the information processing device calculates the difference value between the display power information and the actual power consumption information of the target user, and whether the actual power consumption information of the target user is accurate or not can be determined based on the difference value, so that the real-time monitoring on the power information of the target user is realized, and the effect of preventing the target user from stealing power is realized.
Example two
Fig. 3 is a schematic structural diagram of a user electricity consumption monitoring system according to a second embodiment of the present invention, and the second embodiment of the present invention may be combined with various alternatives in the foregoing embodiments. In this embodiment of the present invention, optionally, the system further includes: a first signal detection device 400 electrically connected to the electricity meter;
optionally, the first signal detection device 400 is configured to collect first signals of electric meters of target users, and send the first signals to the information processing device 300; and the information processing device 300 is configured to receive the first signal and a second signal on each electric meter, which is acquired by a sensor in the electric meter of each target user, calculate a second difference between the first signal and the second signal, and determine that the electric quantity of the target user is abnormal if the second difference is greater than a second preset difference threshold.
For example, the first signal detection device may be a device for acquiring a signal of an 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 here may be, for example, a detection CT. The first signal detection device may be disposed at a line incoming side of the electric meter of each target user.
The first signal may be a current signal and/or a voltage signal of the electricity meter of each target user detected by the first signal detecting device.
The second signal may be a current signal and/or a voltage signal of the target user's electric meter collected by an on-board sensor in the target user's electric meter.
The second difference may be a difference of the first signal and the second signal.
The second preset difference threshold may be a preset second difference threshold, and when the second difference is smaller than or equal to the threshold, it is determined that the electric meter of the target user is not faulty, and the fact that the actual consumed electric quantity information of the target user is not consistent with the display electric quantity information displayed on the electric meter is caused by abnormal electricity consumption of the target user, it is determined that the abnormal electricity consumption of the target user may exist.
It should be noted that, the collected first signal may also be a first signal that is collected only the electric meter of the target user whose first difference determined in the first embodiment is greater than the first preset difference threshold; correspondingly, the second signal may be only the second signal of the electric meter of the target user whose first difference determined in the first embodiment is greater than the first preset difference threshold. Therefore, only the signals of the electric meters of the target users with the first difference value larger than the first preset difference value threshold value need to be acquired, and the signals of the electric meters of all the target users do not need to be acquired, so that the time is saved, and the detection efficiency is improved.
In order to avoid that the calculated first difference is larger than the first preset difference threshold value, which is caused by the fault of the ammeter, that is, the ammeter may have the fault, so that an error may occur in the acquired displayed electric quantity information of the ammeter, and thus the first difference is larger than the first preset difference threshold value, which may cause the detection that the electricity consumption of the target user may be abnormal, but the electricity consumption of the target user is not abnormal, so that the fault factor of the ammeter needs to be eliminated, and therefore, whether the ammeter has the fault or not is determined according to the difference between the acquired first signal and the acquired second signal of the ammeter. If the second difference value between the first signal and the second signal is smaller than or equal to the second preset difference value threshold, the electric meter is not in fault, and therefore it is determined that the fact that the first difference value is larger than the first preset difference value threshold is caused by the abnormal electricity utilization of the target user.
Therefore, misjudgment caused by failure of the sensor of the ammeter is avoided, and the accuracy of judging whether the electricity consumption of the target user is abnormal is improved.
Referring to the information processing execution diagram of the information processing apparatus shown in fig. 4, step11-step13 in fig. 4 are steps of information processing performed by the information processing apparatus in the first embodiment. Step14-step17 in fig. 4 are steps of processing information by the information processing apparatus according to the second embodiment of the present invention.
According to the technical scheme of the embodiment of the invention, the first signal detection equipment is designed and used for acquiring the first signal of the ammeter of each target user and sending the first signal to the information processing equipment; and the information processing equipment receives the first signal and a second signal on each ammeter acquired by a sensor in each target user ammeter, calculates a second difference value between the first signal and the second signal, and determines that the electric quantity of the target user is abnormal if the second difference value is greater than a second preset difference value threshold. Therefore, misjudgment caused by failure of the sensor of the ammeter is avoided, and the accuracy of judging whether the electricity consumption of the target user is abnormal is improved.
EXAMPLE III
Fig. 5 is a schematic structural diagram of a user electricity utilization monitoring system according to a third embodiment of the present invention, and the third embodiment of the present invention may be combined with various alternatives in the foregoing embodiments. In this embodiment of the present invention, optionally, the system further includes: a third information collecting device 500 electrically connected to the information processing device;
optionally, the third information collecting device 500 is configured to collect a total of actual power consumption information of each target user, and send the total of the actual power consumption information to the information processing device 300; an information processing device 300 for determining the actual consumption electric quantity information sum of each target user based on the actual consumption electric quantity information of the electric meter of each target user; and calculating a third difference value between the actual power consumption information sum and the actual consumed power information sum, and if the third difference value is greater than a third preset difference value threshold value, determining that the power consumption of each target user is abnormal.
For example, the third information collecting apparatus may be an apparatus for collecting the sum of actual power usage information of each target user. For example, it may be a gateway meter provided at the transformer end.
The total of the actual electricity usage information may be the total of the actual electricity usage information of all the target users.
The information processing equipment obtains the sum of the actual consumed electric quantity information of each target user according to the actual consumed electric quantity information of the electric meters of each target user, which is acquired by the first information acquisition equipment, and the sum of the actual consumed electric quantity information of all target users, which is acquired by the first information acquisition equipment, is obtained.
The third difference value may be a difference value of the sum of the actual used amount information and the sum of the actual consumed amount information.
The third preset difference threshold may be a preset third difference threshold, and 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 by the actual power consumption information collected by the first information, and it indicates that there may be an abnormality in power consumption of the target user.
And the information processing equipment calculates the difference value between the sum of the actual power consumption information and the sum of the actual consumed electric quantity information according to the obtained sum of the actual power consumption information and the sum of the actual consumed electric quantity information, and when the difference value between the sum of the actual power consumption information and the sum of the actual consumed electric quantity information is larger than a third preset difference threshold value, the fact that the electricity consumption of the target user is possibly abnormal is indicated. Step1-step3 in fig. 4 are steps of processing information by the information processing apparatus in the third embodiment of the present invention.
In this way, whether the power consumption of the target user is abnormal or not can be judged by calculating the total power consumption information of all the target users, and if it is not determined that the power consumption of the target user is abnormal by calculating the total power consumption information of all the target users, the step of calculating the power consumption information of a certain target user in the following step, that is, the step of processing the information by the information processing apparatus in the first embodiment and the second embodiment, does not need to be executed. Therefore, time is saved, and detection efficiency is improved.
According to the technical scheme of the embodiment of the invention, the actual power consumption information sum of each target user is obtained by designing the third information acquisition equipment, and the information processing equipment determines the actual power consumption information sum of each target user based on the actual power consumption information of the ammeter of each target user; and calculating a third difference value between the actual power consumption information sum and the actual consumed power information sum, and if the third difference value is greater than a third preset difference value threshold value, determining that the power consumption of each target user is abnormal. Therefore, whether the power consumption of the target user is abnormal or not can be judged by calculating the total power consumption information of all the target users, if the power consumption of the target user is not abnormal, the step of calculating the power consumption information of a certain target user in the follow-up process is not needed, the time is saved, and the detection efficiency is improved.
Example four
Fig. 6 is a schematic structural diagram of a user electricity utilization monitoring system according to a fourth embodiment of the present invention, and the fourth embodiment of the present invention may be combined with various alternatives in the foregoing embodiments. In this embodiment of the present invention, optionally, the system further includes: a second signal detection device 600 electrically connected to the first information collection device;
optionally, the second signal detecting device 600 is configured to collect a third signal of the first information collecting device 100, and send the third signal to the information processing device 300; the information processing device 300 is configured to receive the third signal and a fourth signal on the first information acquisition device 100 acquired by a sensor in the first information acquisition device 100, calculate a fourth difference between the third signal and the fourth signal, and determine that the electric quantity of the target user is abnormal if the fourth difference is greater than a fourth preset difference threshold.
For example, the second signal detection device may be a device for acquiring a signal of the first information acquisition device, where the signal may be, for example, a voltage signal and/or a current signal, etc. The second signal detection device here may be, for example, a detection CT. The second signal detection device may be provided on the incoming line side of the second information collection device (concentrator).
The third signal may be a current signal and/or a voltage signal of the first information collecting device detected by the second signal detecting device.
The fourth signal may be a current signal and/or a voltage signal of the first information-collecting device collected by its own sensor in the first information-collecting device.
The fourth difference may be a difference of the third signal and the fourth signal.
The fourth preset difference threshold may be a preset fourth difference threshold, and when the fourth difference is greater than the threshold, it is determined that the first information acquisition device may have a fault.
In order to avoid that the calculated third difference is larger than the third preset difference threshold value due to a fault of the electricity meter, that is, the first information acquisition device (concentrator) may have a fault, so that an error may occur in the acquired actual power consumption information of the electricity meter, that is, the third difference is larger than the third preset difference threshold value, which may cause that the power consumption of the target user is detected to be abnormal, but the power consumption of the target user is not abnormal, and therefore, a fault factor of the first information acquisition device itself needs to be eliminated, so that whether the first information acquisition device has a fault is determined according to a difference between the acquired third signal and the acquired fourth signal of the first information acquisition device. And if the fourth difference value of the third signal and the fourth signal is greater than the fourth preset difference value threshold, which indicates that the first information acquisition device has a fault, executing the steps of step7-step10 in fig. 4. And if the fourth difference value between the third signal and the fourth signal is smaller than the fourth preset difference threshold value, determining that the third difference value is larger than the third preset difference threshold value because the power utilization abnormality of one or more target users exists in all the target users.
Note that, the procedure of processing the fourth signal and the third signal by the information processing apparatus is as the steps of step4-step6 in fig. 4.
Therefore, misjudgment caused by failure of the sensor of the first information acquisition equipment is avoided, and the accuracy of judging whether the electricity consumption of the target user is abnormal is improved.
Optionally, as shown in step7-step10 in fig. 4, after determining that the fourth difference is greater than the fourth preset difference threshold, the information processing apparatus 300 is further configured to: based on the third signal, calculating the sum of the electric quantity consumption information of each target user acquired by the first information acquisition device 100 to obtain the sum of the electric quantity consumption information; replacing the actual consumed electric quantity information sum with the electric quantity consumption information sum, recalculating a fifth difference value between the electric quantity consumption information sum and the actual power consumption information sum, and determining that the electric quantity of each target user is abnormal if the fifth difference value is greater than a fifth preset difference value threshold.
For example, the sum of the power consumption information may be obtained according to the third signal of the first information collection device collected. For example, if the third signal is a current signal and a voltage signal, the power consumption information of each target user that should be actually acquired by the first information acquisition device can be obtained according to the formula P ═ UI based on the acquired current signal and voltage signal of the first information acquisition device, and the sum of the power consumption information of all the target users that are actually acquired can be obtained based on the power consumption information of each target user that is actually acquired.
And replacing the obtained sum of the electric quantity consumption information with the obtained sum of the actual electric quantity consumption information of the electric meters of all the target users according to the actual electric quantity consumption information of the electric meters of all the target users, which is collected by the first information collection equipment. And calculating the difference value between the replaced actual consumed electricity information sum and the actual electricity consumption information sum of all the target users acquired by the third information acquisition equipment, comparing the difference value with a third preset difference value threshold, and executing step11 if the difference value is greater than the third preset difference value threshold.
Therefore, if the first information acquisition equipment has faults, whether the electricity utilization of the target user is abnormal or not can be determined, the normal monitoring of the electricity utilization information of the target user is ensured, and the electricity stealing effect is prevented.
According to the technical scheme of the embodiment of the invention, the second signal detection equipment is designed and used for acquiring the third signal of the first information acquisition equipment; the information processing equipment receives the third signal and a fourth signal on the first information acquisition equipment, which is acquired by a sensor in the first information acquisition equipment, calculates a fourth difference value of the third signal and the fourth signal, and determines that the electric quantity of the target user is abnormal if the fourth difference value is greater than a fourth preset difference value threshold value, so that misjudgment caused by failure of the sensor of the first information acquisition equipment is avoided, and the accuracy of judging whether the electric quantity of the target user is abnormal is improved. Meanwhile, the information processing apparatus is further configured to: calculating the sum of the electric quantity consumption information of each target user acquired by the first information acquisition equipment based on the third signal to obtain the sum of the electric quantity consumption information; replacing the actual consumed electric quantity information sum with the electric quantity consumption information sum, recalculating a fifth difference value between the electric quantity consumption information sum and the actual power consumption information sum, and determining whether the electric quantity of each target user is abnormal if the fifth difference value is greater than a fifth preset difference value threshold value, so that whether the power consumption of the target user is abnormal can be determined if the first information acquisition equipment has a fault, normal monitoring of the power consumption information of the target user is ensured, and the effect of preventing electricity stealing is achieved.
