Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to an electric meter terminal and a data processing method and system thereof. Background Art

[0002] In different regions, there are differences in the calculation methods of electricity prices for residential users, which can be specifically divided into time-of-use electricity prices and tiered electricity prices. Among them, time-of-use electricity prices set different electricity prices according to different periods of electricity consumption. For example, during peak electricity consumption periods, electricity prices may be higher; while during low electricity consumption periods, electricity prices will be lower. The tiered electricity price is divided into multiple levels according to the user's monthly electricity consumption. As the electricity consumption increases, the electricity price increases step by step. For example, the first level of electricity consumption covers 0 to 200 degrees, the second level is 201 to 400 degrees, and the third level is above 401 degrees. There are differences in electricity prices for different levels.

[0003] The electricity consumption of residential users is usually calculated by using an electric meter, and the electricity fee that the household needs to pay is calculated based on the electricity price. The electricity fees that different residential users need to pay are different according to their electricity usage habits and needs. Among them, taking time-of-use electricity prices as an example, if the amount of electricity used by residential users during peak hours is large, the electricity fee they need to pay will be higher. Therefore, how to reasonably reduce the electricity expenses of residential users and the electricity burden of the power grid has become an urgent problem to be solved. Summary of the invention

[0018] Detecting the current and voltage flowing through the electric meter terminal multiple times and generating multiple units of time-length electric power usage data;

[0019] The power usage data of multiple unit durations are arranged in chronological order.

[0020] Optionally, after the step of arranging the power usage data of the plurality of unit durations in chronological order, the method further comprises:

[0021] The electricity usage data per unit time period higher than the first household's electricity consumption is defined as a high electricity consumption period;

[0022] The electricity usage data per unit time period is less than the second household's electricity usage, which is defined as a low electricity usage period;

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 The above is a schematic diagram of the main process of an embodiment of a data processing method for an electric meter terminal provided by the present invention. Figures 2 to 3 As shown, the method of the present invention is applied to an electric meter terminal system, the electric meter terminal system includes an electric meter terminal, an energy storage device, and a cloud, the electric meter terminal is electrically connected to the energy storage device, the electric meter terminal is communicatively connected to the cloud, and the method includes:

[0045] Step S100: Acquire fluctuation data of power usage within a period of the location where the electric meter terminal system belongs and operation data of the energy storage device;

[0046] Step S200: acquiring power usage data detected by the electric meter terminal within a period of the location where the electric meter terminal system belongs;

[0047] Step S300: Controlling the energy storage device to perform charging and discharging actions according to the degree of overlap between the fluctuation data and the power usage data, and the operation data.

[0048] In this embodiment, in order to ensure the maximization of the benefits of residential users, it is first necessary to obtain the fluctuation data of electricity use in the energy storage system within a cycle. It is understandable that there are often certain differences in electricity prices in different regions. Specifically, the distribution of natural resources in different regions is different. Some regions are rich in hydropower resources, while others rely on other energy sources such as coal or natural gas. The cost difference of these resources directly affects the cost of power generation, and then affects the local electricity price. In addition, the electricity prices in different regions are also affected by factors such as supply and demand, regional economic development level, etc. Further, for different regions, the electricity prices in the same time period are also different. For example, in more developed areas, the electricity consumption at night is also at a higher level, while in less developed areas, the electricity consumption at night is at a lower level, and this supply and demand relationship will also lead to different electricity prices. Therefore, it is indispensable to obtain the fluctuation data of electricity use in the area where the meter terminal system belongs within a cycle. Among them, the setting of the cycle will be set according to the fluctuation data of electricity use in the area where the meter terminal system belongs. For example, if the fluctuation data of each day in the area where the meter terminal system belongs is within the preset range of variation, the cycle can be set to one day. For another example, if the weekly fluctuation data of the location where the meter terminal system belongs is within the preset range of variation, the period can be set to one week. Furthermore, the acquisition of fluctuation data can be obtained by the control device or the cloud for subsequent judgment. In addition, while confirming the fluctuation data of electricity use in a cycle at the location where the meter terminal system belongs, it is also necessary to confirm the operating data of the energy storage device in order to confirm the maximum storage capacity, maximum output power, and energy storage capacity of the energy storage device during charging and discharging operations.

[0049] In this embodiment, the meter terminal can detect the electricity consumption of the residential user, and upload the detected data to the cloud, so that the cloud can confirm the electricity fee to be paid by the resident user according to the electricity consumption of the resident user. Among them, the meter terminal will continuously obtain the electricity consumption of the resident user. Specifically, take one cycle as one day as an example. The sensor built into the meter terminal will measure the current and voltage flowing through the circuit, and the product of the current and voltage is the instantaneous power. In order to obtain the electricity consumption of the resident user in one day, the meter terminal will integrate the instantaneous power. This means that the meter terminal will continue to record the instantaneous power and accumulate it over time. This accumulated value is the total electricity consumption of the resident user in one day, usually in kilowatt-hours. Further, the instantaneous power of the resident user in one day is arranged in chronological order, so that it can be confirmed in which time period the resident user consumes more electricity and in which time period the electricity consumption is less, and then the electricity consumption habits of the resident user are confirmed. For example, the resident user consumes more electricity at night or more electricity during the day.

[0050] It can be understood that by obtaining the fluctuation data of electricity usage within a period of the location where the meter terminal system belongs and the electricity usage data detected by the meter terminal, and comparing the data of the two for coincidence, the similarity between the electricity usage pattern of the resident user and the electricity usage within a period of the location where the meter terminal system belongs can be confirmed. When the similarity between the two is high, it can be confirmed that the resident user consumes more electricity when the electricity price is higher, and then needs to pay more fees under the condition of the same electricity consumption. Therefore, the cloud can control the energy storage device to perform charging and discharging actions in the corresponding time period by confirming the coincidence of the two and the operating data of the energy storage device. For example, when the power grid price is low, the energy storage device is controlled to charge, and when the power grid price is high, it replaces the power grid to supply power to the electrical equipment.

[0051] In this embodiment, the fluctuation data of electricity usage in a cycle of the location where the meter terminal system belongs is obtained through the cloud, so as to confirm the usage pattern of the location where the meter terminal system belongs in a cycle, and judge when the electricity consumption of the location where the meter terminal system belongs is large, when the electricity consumption is moderate, and when the electricity consumption is low in the cycle, and obtain the electricity price corresponding to each time period in the cycle. Further, by obtaining the operation data of the energy storage device, the amount of electricity that the energy storage device can store and its charge and discharge rate are confirmed. After confirming the fluctuation data and operation data, the electricity usage of the resident user in a cycle is obtained through the meter terminal detection, and then it is determined when the resident user uses more electricity and when the resident user uses less electricity. By confirming the overlap between the fluctuation data and the electricity usage data, and further confirming the operation data of the energy storage device, the energy storage device is controlled to perform charging and discharging actions, so as to reduce the use of electricity in the power grid by the resident user when the electricity price is high, effectively reducing the electricity bill expenditure of the resident user and the electricity burden of the power grid.

[0052] refer to Figure 2 In one embodiment of the present invention, in step S100, the step of obtaining the fluctuation data of power usage in a cycle at the location of the electric meter terminal system and the operation data of the energy storage device specifically includes:

[0053] Step S110: obtaining the peak period, the valley period and the stable period of electricity usage in a cycle of the location where the electric meter terminal system belongs;

[0054] Step S120: generating fluctuation data of the energy storage system within a period according to the peak power consumption period, the valley power consumption period and the stable power consumption period;

[0055] Step S130: Obtaining the charging rate, discharging rate and electric energy storage ratio of the energy storage device;

[0056] Step S140: generating operation data of the energy storage device according to the charging rate, the discharging rate and the electric energy storage ratio.

[0057] In this embodiment, the use of electricity in a cycle at the location of the meter terminal system can be divided into a peak period, a valley period and a stable period according to the power consumption per unit time. Further, the specific steps of obtaining the peak period, valley period and stable period of electricity use at the location of the meter terminal system in a cycle include: obtaining the situation of electricity in a cycle at the location of the meter terminal system, and setting the time period when the power consumption per unit time is greater than the first power consumption as the peak period, setting the time period when the power consumption per unit time is less than the second power consumption as the valley period, and setting the time period when the power consumption per unit time is between the first power consumption and the second power consumption as the stable period. Among them, the peak period is generally in the morning and evening, when most residents start to use a large number of electrical appliances, such as air conditioners, lighting, cooking equipment, etc. During these periods, the power supply is tight and the pressure on the power grid is large, so the electricity price is usually high. The valley period is generally between late night and early morning, when most people have rested and the power consumption is reduced. During these periods, the power supply is sufficient and the pressure on the power grid is small, so the electricity price is low. The first power setting and the second power setting can be set according to the power consumption in a unit time. For example, the power consumption in a unit time is sorted from high to low. When it is higher than a certain limit of the average power consumption in a unit time, the unit time period is confirmed as a peak power consumption period; when it is lower than a certain limit of the average power consumption in a unit time, the unit time period is confirmed as a valley power consumption period. By confirming the peak power consumption period, valley power consumption period and stable power consumption period in a cycle of the area where the energy storage system is located, the fluctuation data of the area in a cycle is determined, and then the electricity price of each time period in a cycle is confirmed.

[0058] In this embodiment, the energy storage device, as a storage device for electric energy, has the function of obtaining or outputting electric energy and storing electric energy through charging and discharging. Among them, the charging rate, discharge rate and electric energy storage ratio of the energy storage device will affect the operation of the meter terminal system. For example, the fluctuation data shows that the use of electricity in a certain period of time belongs to the low electricity consumption period, that is, the electricity price in this period of time is at a low price. The meter terminal should control the energy storage device to perform charging actions to obtain electric energy at a low price. However, at this time, it is necessary to consider the electric energy storage ratio in the energy storage device. If the electric energy storage ratio is in a saturated state, the charging action cannot be performed. If the electric energy storage ratio has not reached the saturated state, the meter terminal needs to control the energy storage device to charge during the low electricity consumption period by adjusting the charging rate to ensure that the energy storage device can increase the electric energy storage ratio of the squeak as much as possible during the low electricity consumption period. Therefore, the meter terminal needs to obtain the charging rate, discharge rate and electric energy storage ratio of the energy storage device to cooperate with the fluctuation data within a period of the meter terminal system, thereby reducing the electricity bill expenditure of residential users and the electricity burden of the power grid.

[0059] refer to Figure 3 In one embodiment of the present invention, in step S200 of the present invention, the specific steps of obtaining the power usage data detected by the electric meter terminal within a period of the location where the electric meter terminal system belongs include:

[0060] Step S210: dividing the duration of a cycle of the electricity meter terminal system into a plurality of unit durations;

[0061] Step S220: Detecting the current and voltage flowing through the electric meter terminal multiple times, and generating multiple unit time lengths of electric power usage data;

[0062] Step S230: Arrange the power usage data of multiple unit durations in chronological order.

[0063] In this embodiment, the duration of a cycle divided by the meter terminal system needs to correspond to the fluctuation data of power usage within a cycle of the meter terminal system. For example, the fluctuation data of power usage within a cycle of the meter terminal system adopts a cycle of one day, and is expressed in hours, that is, 0 to 6 o'clock is the low power consumption period, 6 to 8 o'clock is the stable power consumption period, etc. At this time, it is necessary to divide a cycle of the meter terminal system into 24 unit durations, that is, a cycle is one day, and each unit duration is 1 hour. By dividing a cycle of the meter terminal system into 24 unit durations, the power consumption of the residential users at 24 moments can be obtained. It can be understood that the meter terminal calculates the power used by the residential users at each moment by detecting the current and voltage flowing through itself, and accumulates the points to obtain the power consumption at the last moment. Further, the meter terminal will obtain the power usage data of each unit duration corresponding to the divided duration. For example, the electric meter terminal can confirm the electricity usage of residential users from 0:00 to 1:00, 1:00 to 2:00, etc. by detecting the current and voltage flowing through itself. Among them, the electric meter terminal will integrate and accumulate the electricity usage data of each unit time, that is, the electricity usage data of residential users from 0:00 to 1:00 and the electricity usage data from 1:00 to 2:00. Thus, the electricity usage data corresponding to each unit time is formed. In addition, in order to ensure that the electricity usage data corresponding to each unit time in a cycle corresponds to the fluctuation data of electricity usage in a cycle in the location where the electric meter terminal system belongs, it is necessary to arrange the electricity usage data of multiple unit time in chronological order for subsequent comparison.

[0064] In one embodiment of the present invention, after the step of arranging the power usage data of the plurality of unit durations in chronological order, the method further comprises:

[0065] The electricity usage data per unit time period higher than the first household's electricity consumption is defined as a high electricity consumption period;

[0066] The electricity usage data per unit time period is less than the second household's electricity usage, which is defined as a low electricity usage period;

[0067] The electricity usage data per unit time period is higher than the second household's electricity usage and lower than the first household's electricity usage as the medium electricity usage period;

[0068] The power usage data detected by the electric meter terminal is generated according to the high power usage period, the low power usage period and the medium power usage period.

[0069] It is understandable that by using the meter terminal to obtain the electricity usage data of the residential users in a cycle, and dividing the cycle into multiple equidistant unit durations, the electricity usage habits of the residential users in a week can be confirmed. Optionally, the meter terminal can feed back the obtained unit duration electricity usage data to the cloud, so that the cloud can further analyze and confirm such data. The meter terminal can also compare and confirm the obtained unit duration electricity usage data with the fluctuation data of electricity usage in a cycle of the meter terminal system issued by the cloud, which depends on whether the processor of the meter terminal itself meets the computing requirements. Among them, the fluctuation data of electricity usage in a cycle of the meter terminal system will be divided into peak electricity consumption period, low electricity consumption period and stable electricity consumption period. Therefore, the unit duration electricity usage data needs to be set according to the average of the peak electricity consumption period, low electricity consumption period and stable electricity consumption period in the fluctuation data, so as to more accurately compare the similarity between the two. Among them, the first household's electricity consumption is the average of the peak period of electricity consumption in the fluctuation data; the second household's electricity consumption is the average of the low period of electricity consumption in the fluctuation data. It can be understood that the high electricity consumption period in the electricity usage data corresponds to the peak period of electricity consumption in the fluctuation data; the low electricity consumption period in the electricity usage data corresponds to the low period of electricity consumption in the fluctuation data; and the medium electricity consumption period in the electricity usage data corresponds to the stable period of electricity consumption in the fluctuation data. Further by arranging in time order, two groups of corresponding change values ​​can be obtained.

[0070] In one embodiment of the present invention, after the step of arranging the power usage data of the plurality of unit durations in chronological order, the method further comprises:

[0071] The power usage data of multiple unit durations in a cycle is stored and uploaded to the cloud, and the power usage data in the cycle is cleared after a first preset duration.

[0072] In this embodiment, the electric meter terminal will accurately detect the power consumption of residential users at every moment through its own current detection module and voltage detection module, and feed back the detected power usage data to the cloud through the communication module through the preset cycle and unit duration. Among them, the power usage data detected by the electric meter terminal will be stored in its internal storage module in advance, and uploaded to the cloud after a cycle, so that the cloud can obtain the power usage data. Furthermore, in order to improve the utilization rate of the internal storage unit of the electric meter terminal and reduce its data redundancy, the electric meter terminal will clear the power usage data within the cycle after obtaining the first preset duration of the power usage data.

[0073] In one embodiment of the present invention, in step S300, the specific steps of controlling the energy storage device to perform charging and discharging actions according to the overlap between the fluctuation data and the power usage data, and the operation data include:

[0074] When it is confirmed that the overlap between the peak electricity consumption period of the electricity usage in a cycle at the location where the electric meter terminal system belongs and the high electricity consumption period is greater than a first preset threshold, the energy storage device is controlled to increase the energy storage ratio in the next cycle, and the energy storage device is controlled to perform a discharge action at a first discharge rate during the high electricity consumption period in the next cycle.

[0075] In this embodiment, the power usage data and fluctuation data will be set to a data format with the same cycle and unit duration. The setting of the first preset threshold value will be set according to the operation data of the energy storage device and the power usage data of the residential user. On the basis that the output ratio of the energy storage device, that is, the power storage ratio, fully meets the needs of the residential user, the first preset threshold value can be set to a lower value. For example, the overlap between the high power consumption period and the peak power consumption period in the same time period is higher than 20%, that is, the first preset threshold value is 20%. In other words, the period of high power consumption of the residential user during the peak power consumption period overlaps by more than 20%. It can be understood that the residential user uses more electricity during the peak power consumption period, and the fee he needs to pay is more than the fee he needs to pay during the low power consumption period. Therefore, after obtaining the power usage data, the meter terminal will confirm that the overlap is greater than the first preset threshold, and then control the energy storage device to increase its power storage ratio before the same time in the next cycle, and control the energy storage device to output power at the first discharge ratio during the high power consumption period in the next cycle, so as to reduce or completely avoid the residential user from obtaining power from the power grid during the peak power consumption period. Among them, the energy storage device will be controlled to perform charging action during the low power consumption period. When the charging rate of the energy storage device is low and it is impossible to increase the energy storage ratio to the required power consumption during the high power consumption period during the low power consumption period, the energy storage device is controlled to perform charging action during the stable power consumption period. It can be understood that controlling the energy storage device to perform charging action during the low power consumption period is a priority choice.

[0076] In one embodiment of the present invention, the specific step of controlling the energy storage device to perform charging and discharging actions according to the overlap between the fluctuation data and the power usage data, and the operation data, further includes:

[0077] When the overlap between the low electricity consumption period and the low electricity consumption period within a cycle of the location to which the electric meter terminal system belongs is less than a second preset threshold, the energy storage device is controlled to reduce the energy storage ratio in the next cycle, and the energy storage device is controlled to perform charging at a first charging rate during the low electricity consumption period in the next cycle.

[0078] In this embodiment, the power usage data and fluctuation data will be set to a data format with the same cycle and unit duration. The setting of the second preset threshold value will be set according to the operation data of the energy storage device and the power usage data of the residential user. On the basis that the output ratio of the energy storage device, that is, the power storage ratio, fully meets the needs of the residential user, the first preset threshold value can be set to a higher value. For example, the overlap between the low power consumption period and the low power consumption period in the same time period is less than 80%, that is, the second preset threshold value is 80%. In other words, the overlap between the period when the residential user consumes less power during the low power consumption period is less than 80%. It can be understood that the residential user uses less power during the low power consumption period, which can be understood as the residential user not being able to fully utilize the lower electricity price during the low power consumption period. Therefore, after obtaining the power usage data, the meter terminal will confirm that the overlap is less than the second preset threshold, and then control the energy storage device to lower its power storage ratio before the same time in the next cycle, and control the energy storage device to charge the power at the first charging rate during the low power consumption period in the next cycle, so as to increase the residential user's access to power from the power grid during the low power consumption period. The energy storage device will be controlled to perform discharge actions during periods of high power consumption.

[0079] refer to Figure 4 The present invention also proposes an electric meter terminal, the electric meter terminal comprising: a memory, a processor, and a data processing program of the electric meter terminal stored in the memory and running on the processor, the data processing program being configured to implement the steps of the data processing method of the electric meter terminal as described in any one of the above. It is worth noting that since the electric meter terminal of the present invention is based on the data processing method of the electric meter terminal described above, the embodiments of the electric meter terminal of the present invention include all technical solutions of all embodiments of the data processing method of the electric meter terminal described above, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0080] In this embodiment, the electric meter terminal detects the current signal and voltage signal of the household 220V AC power to confirm the power consumption of the residential user. The internal power supply is set to power it, so as to meet the power supply demand of the electric meter terminal itself. Among them, the internal power supply can convert the 220V AC power into DC power through the voltage conversion circuit to realize power supply, and a small energy storage device such as a lithium battery can also be used for power supply. The LCD display is a liquid crystal display, which is used to display the working status of the electric meter terminal and the data obtained by its detection. The communication module is used for data interaction between the electric meter terminal and the cloud.

[0081] The present invention further proposes an electric meter terminal system, which includes an energy storage device, a cloud, and the electric meter terminal as described above. It is worth noting that since the electric meter terminal system of the present invention is based on the above-mentioned electric meter terminal, the embodiments of the electric meter terminal system of the present invention include all technical solutions of all embodiments of the above-mentioned electric meter terminal, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0082] The implementation of the embodiments of the present invention has the following beneficial effects:

[0083] The present invention provides an electric meter terminal and a data processing method and system thereof. By accurately acquiring the power usage fluctuation data of the area where the electric meter terminal system is located and the power usage data of residential users, and combining the operation data of the energy storage device, the present invention can intelligently control the energy storage device to charge when the electricity price is low and discharge when the electricity price is peak, thereby effectively reducing the electricity bill expenditure of residential users during the peak electricity price period.

[0084] In the present invention, through the charge and discharge management of the energy storage device, the present invention helps to balance the supply and demand relationship of the power grid. During the peak period of electricity consumption, the energy storage device can release the stored electric energy to reduce the power supply pressure of the power grid; during the low period of electricity consumption, the energy storage device can absorb excess electric energy to avoid waste of the power grid. This balancing mechanism helps to improve the stability and efficiency of the power grid.

[0085] In the present invention, the charging and discharging of the energy storage device is intelligently controlled, so that the electric energy is used more reasonably and efficiently. Charging when the electricity price is low and discharging when the electricity price is high not only reduces the user's electricity bill expenditure, but also improves the utilization efficiency of the entire energy system.

[0086] In the present invention, by confirming the overlap between the fluctuation data and the power usage data, and further confirming the operation data of the energy storage device, the energy storage device is controlled to perform charging and discharging actions, so as to reduce the use of electric energy in the power grid by residential users when the electricity price is high, thereby effectively reducing the electricity bill expenditure of residential users and the electricity consumption burden of the power grid.
