Description

A single-phase fee-controlled energy meter based on the Internet of Things Technical Field

[0001] The present invention belongs to the technical field of electric energy meters, and in particular to a single-phase fee-controlled electric energy meter based on the Internet of Things. Background Art

[0002] Smart meters are one of the basic devices for smart grid data collection. They are responsible for collecting, measuring and transmitting original electric energy data, and are the basis for realizing information integration, analysis optimization and information display. In addition to the basic electricity consumption metering function of traditional electric energy meters, in order to adapt to the use of smart grids and new energy, smart meters also have two-way multi-rate metering function, user-side control function, two-way data communication function with multiple data transmission modes, anti-electricity theft function and other intelligent functions.

[0003] Electricity meters commonly used in homes or factories are usually used to monitor electricity usage, including the amount of electricity used per unit time and the resulting electricity charges. Regarding the cost issue, some users may experience problems with the meter's installation or the usage environment. For example, if the humidity in the environment is too high, moisture from rainy weather may migrate along the wall to the meter's installation location, corroding the circuit components inside the meter and causing internal faults. Users fail to discover and repair the meter in a timely manner, causing the meter to continue operating despite the fault.

[0004] Such measurement failures will lead to abnormalities in the measured electricity meter data, resulting in the measured data being too large or too small. In this way, when the charges are settled during the final meter reading, they will not be consistent with the actual normal electricity consumption, which will cause losses to users or power supply departments. Of course, it is also possible that some users will modify the data of the electricity meter on their own, and the payers will fail to discover the mistakes in time due to their busy work, thereby realizing their bad intention of paying less electricity bills, causing losses to the power supply department.

Modes for Carrying Out the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings shown in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] A single-phase cost-controlled energy meter based on the Internet of Things (IoT) is commonly used in homes or factory workshops to monitor electricity usage, including the amount of electricity used per unit time and the resulting electricity charges. Regarding the cost issue, some users may experience meter failures due to problems with meter installation or the usage environment. For example, if the humidity in the usage environment is too high, moisture from rainy weather may migrate along the wall to the meter installation area, corroding the circuit components inside the meter, causing internal faults in the meter. If the user fails to discover and repair the meter in a timely manner, the meter may continue to operate despite the fault.

[0040] Such measurement failures will lead to abnormalities in the measured electricity meter data, such as the measured data being too large or too small. When the final meter reading is completed and the bill is settled, it will not match the actual normal electricity consumption, which will cause losses to users or power supply departments. Of course, it is also possible that some users will modify the electricity meter data on their own, and the bill payers may fail to discover the mistakes in time due to their busy work, thereby realizing their bad intention of paying less electricity bills, causing losses to the power supply department.

[0041] Therefore, in order to effectively solve the above problems, the present application proposes a single-phase fee-controlled electric energy meter based on the Internet of Things, as shown in Figures 1-10 of the accompanying drawings of the specification, comprising a meter body 1 and an intelligent working system. The meter body 1 is the main part of the electric energy meter and is internally provided with various circuit components for electricity metering. A mounting base 2 is provided on the back of the meter body 1. The mounting base 2 is tightly fixed to the meter body 1 by screw connection or welding.

[0042] The mounting base 2 is evenly provided with fixing holes 23. The installer can connect the mounting base 2 to the wall surface to be installed by screws through the fixing holes 23, thereby achieving relative fixation between the mounting base 2 and the wall, thereby achieving fixation of the meter body 1. A display screen 11 is provided on the front of the meter body 1, and a connecting wire 12 is installed on the bottom of the meter body 1. The connecting wire 12 connects the interior of the meter body 1 to the power transmission line, and is connected to each electrical device and the input wire to transmit the power consumption data of each user's electrical device to the intelligent working system inside the meter body 1 for power consumption metering.

[0043] The intelligent working system includes: intelligent processor, power calculation module, electricity fee calculation module, display module, information transmission module, alarm module and security module;

[0044] The power calculation module is used to calculate the user's total power consumption, and the electricity fee calculation module automatically settles the electricity fee according to the stored electricity fee pricing model; and both the power calculation module and the electricity fee calculation module display the power consumption information and electricity fee information to the user through the display module. The intelligent processor provides calculation support for the power calculation module and the electricity fee calculation module. The intelligent processor, power calculation module and electricity fee calculation module here are all functions of the electric energy meter in the prior art, and the specific structure and implementation method are not described in detail here;

[0045] The information transmission module includes a transmitter and an IoT connection port. After authorization, it can connect to the power supply department network based on the IoT, timely update the electricity price calculation model stored in the electricity fee calculation module, and at the same time, immediately feed back the power consumption information and electricity fee information to the corresponding user-end APP and electricity fee collection department;

[0046] The protection module includes a humidity sensor and a temperature sensor, both of which are installed inside the meter body 1. When the humidity or temperature exceeds the safety value, an alarm is sounded through the alarm module. The alarm module can be a red warning light set on the outside of the meter body 1. When an alarm is required, a red light is emitted to remind the user that a fault has occurred inside the meter body 1 and that maintenance and repair should be carried out in time to eliminate the fault and ensure the normal operation of the meter body 1. Of course, the corresponding notification information can also be edited through the information transmission module and fed back to the corresponding user-end APP in a timely manner, so that users who are not on site can promptly understand the specific situation.

[0047] Specific working process: During the operation of the electric energy meter, the mounting base 2 is fixed to the wall to maintain stability. A plurality of connecting wires 12 are provided at the bottom of the meter body 1. The connecting wires 12 include lines for connecting to electrical devices, which can provide timely feedback of electricity consumption-related data of the electrical devices; they can also be data lines for connecting to the network. When the wireless connection method is unstable, a wired connection is used to ensure information exchange with the Internet of Things related network;

[0048] In this way, the power calculation module arranged inside the meter body 1 can also quickly measure the power usage of various electrical devices according to the usage status of each device, thereby obtaining the total power consumption of the user, and then transmit the power consumption information to the electricity fee calculation module. The electricity fee metering module calculates the electricity fee usage status in a timely manner according to the calculation formula corresponding to the electricity fee calculation mode stored in itself, and quickly feeds back to the user and the power supply department. At the same time, it will also be displayed on the display screen 11 on the front of the meter body 1 through the display module for the user to view.

[0049] During this process, the calculated electricity consumption information and electricity fee information are instantly transmitted to the power supply department through the information transmission module via the sending device and the data network. This allows users to obtain electricity consumption information in real time, preventing bad users from tampering with data before payment time in an attempt to pay less electricity fees and causing losses to the power supply department. The immediately updated electricity consumption information can serve as important evidence to accuse such bad behavior.

[0050] And for some users with large electricity consumption, statistical charts such as line charts can be set according to their daily electricity consumption status to observe their electricity consumption status at different times. When the electricity consumption increases sharply, it is judged that there may be a risk of leakage and overload, which should cause a safety accident. If it is agreed with the user in advance, the power supply to the user can be cut off at the same time as the reminder message is automatically sent; the reminder message is sent to the user-side app for timely notification, and after the user checks to confirm that there is no problem, the power supply department is fed back to restore the power supply. This can avoid accidental electrical accidents such as leakage for users with large electricity consumption; and when an accident occurs, it can be reported in time, and measures can be taken to reduce losses and control the scope of the disaster;

[0051] Some users neglect to maintain the energy meter after installing it. In southern cities, the humidity is high during the rainy season, especially in rainy weather. Moisture will spread rapidly along the wall, and even water droplets generated by moisture will slide down the wall. When such moisture approaches the meter body 1, it may penetrate into the inside of the meter body 1 and cause corrosion of the circuit components inside the meter body 1, thereby causing the energy meter to malfunction. Therefore, the humidity sensor and temperature sensor in the protection unit are installed inside the meter body 1. The humidity sensor can timely sense the humidity condition inside the meter body 1 and provide timely feedback to the user-side APP for the user to understand. When the humidity exceeds the safety threshold, it may cause the energy meter to malfunction or even cause accidents such as leakage. The alarm module should be used to quickly alert the user and the power supply department.

[0052] When the user is away, the power supply department can contact the user by phone to ensure that the user is informed in time and decide whether to take temporary power-off measures to ensure the safe operation of the electricity meter and the connected electrical equipment; the temperature sensor can effectively detect internal temperature changes. When the temperature inside the electricity meter suddenly changes drastically and exceeds the safety threshold, overload and other faults may occur. The alarm module can be quickly activated to alarm, and the situation is fed back to the power supply department through the information transmission module. The power-off measures are quickly taken, and after notifying the user by phone, it is decided whether to carry out on-site maintenance. This can further reduce the occurrence of electrical accidents, ensure the normal use of the electricity meter, and improve the user experience.

[0053] Example 2:

[0054] On the basis of the first embodiment, as shown in FIG1 of the accompanying drawings of the specification, the information transmission module is connected to the smart clock 3 where the user is located via a connecting line 12. Here, the smart clock 3 is a related smart time device in the prior art that can connect to the network and automatically update time information; this timely assists the internal time information of the watch body 1, and through the alarm reminder function inside the smart clock 3, timely reminds the payment time;

[0055] Specific workflow: Based on the specific workflow in Example 1, because the information transmission module needs to send relevant electricity consumption information at regular intervals, the time data needs to be updated in a timely manner; the time information can usually be updated through the connected Internet of Things, but when an internal software problem occurs, the update fails, so that the data information of the home smart clock 3 can be obtained under the control of the intelligent processor; because the smart clock 3 will also update the time information in a timely manner, and because compared with the electricity meter that is not often checked, the smart clock 3 is a device that is paid attention to every day, when there is a problem with the time on it, the user can promptly discover and correct it; at the same time, the corrected time information will be transmitted to the information transmission module inside the meter body 1, and the time information will be corrected in a timely manner to ensure that the electricity consumption information and the time information are accurately corresponding, so as to reduce errors in payment information and reduce losses to users or power supply departments;

[0056] Furthermore, the alarm module can also be connected to the smart clock 3, and the alarm information of the electricity meter failure and the notification information urging payment can be reflected in time through the alarm module on the smart clock 3. In this way, the user is informed by the alarm to take timely measures or pay in time, thereby improving usage efficiency.

[0057] Example 3:

[0058] On the basis of the first embodiment, as shown in Figures 1-6 of the accompanying drawings of the specification, the protection module further includes a protection tube 4, the other end of which can be connected to the air pump device; and the air pump device has its own power supply and is not connected to the user's power line. The air pump device is used to fill the inside of the protection tube 4 with dry and clean airflow, and an existing dehumidification and drying device can be provided at the air inlet pipe of the air pump device to achieve drying of the incoming air; an adjustment chamber 21 is provided inside the mounting base 2, and the protection tube 4 is communicated with the interior of the adjustment chamber 21 and is used to input dry airflow into the interior of the adjustment chamber 21; adjustment holes 22 are evenly provided on the portion of the end of the mounting base 2 facing the safety wall, and the adjustment holes 22 are communicated with the interior of the adjustment chamber 21;

[0059] Specific workflow: Based on the specific workflow in Example 1, a humidity sensor is also provided on the mounting base 2 of the electric meter. Because the mounting base 2 is located between the meter body 1 and the wall and is in close contact with the wall, in rainy weather, moisture spreads along the wall, approaches the meter body 1, and needs to pass through the mounting base 2 to spread into the inside of the meter body 1. Therefore, when the humidity sensor on the mounting base 2 detects that the humidity is high and may pose a threat to the inside of the meter body 1, the protection module quickly issues an alarm through the alarm module and starts the air pump device located on the outside, so that dry and clean air flows through the protection pipe 4 into the adjustment chamber inside the mounting base 2, and then the air flows through the adjustment chamber 21 into the surrounding adjustment hole 22 and flows out from the opening of the adjustment hole 22.

[0060] Because the adjustment holes 22 are evenly arranged at the end of the mounting base 2, and the opening direction of the adjustment holes 22 is centered on the meter body 1 and diverges in the direction away from the meter body 1, the outflowing airflow, after washing the wall surface around the mounting base 2, prompts the air on the wall surface to flow in the direction away from the meter body 1. While the air flow accelerates the evaporation of the surrounding humidity, it also effectively expels the surrounding moisture, ensuring the dryness of the environment around the meter body 1, so that the electric energy meter can work normally; in this way, the air pump device starts regularly to expel moisture until the user turns off this function, or the humidity sensor located on the mounting base 2 detects that the humidity of the surrounding environment begins to drop, at which time the air pump device will be turned off.

[0061] Example 4:

[0062] Based on the third embodiment, as shown in Figures 1-6 of the accompanying drawings, the adjustment hole 22 passes through the middle of the fixing hole 23, and the width of the adjustment hole 22 is larger than the diameter of the fixing hole 23. The dry airflow inside the adjustment hole 22 dries the fixing screw inside the fixing hole 23 to ensure its normal operation.

[0063] Specific workflow: Based on the specific workflow in Example 3, the mounting base 2 is relatively fixed to the wall surface by using fixing screws that pass through the fixing holes 23 and are nailed into the wall surface. When the humidity on the wall surface is high, moisture spreads along the fixing screws, which may cause the fixing screws to rust, thus weakening the fixing effect and causing the mounting base 2 to fall off with the watch body 1. In addition, the rusted fixing screws may also be misaligned with the fixing holes 23, and rust may also be embedded in the gap between the fixing holes 23 and the fixing screws, making disassembly difficult. Forced disassembly may also damage the fixing screws and the fixing holes 23, causing inconvenience to the installation of the mounting base 2.

[0064] Therefore, an adjustment hole 22 is provided to pass horizontally through the middle position of the fixing hole 23, without affecting the connection between the fixing screw and the fixing hole 23. When the air pump equipment is started to dehumidify and dry the area around the installation wall, the flowing airflow flows along the adjustment hole 22 through the fixing hole 23. During this process, a part of the airflow will be blocked by the fixing screw inside the fixing hole 23 and flow along the gap between the fixing screw and the fixing hole 23. The flowing dry air can accelerate the evaporation of water in the gap and expel the approaching moisture, ensuring that the gap between the fixing screw and the fixing hole 23 remains dry, thereby slowing down the rusting of the fixing screw, ensuring the normal functioning of the fixing hole 23 and the fixing screw, and further ensuring the stable fixation of the mounting base 2.

[0065] Embodiment 5:

[0066] Based on the fourth embodiment, as shown in Figures 1-9 of the accompanying drawings of the specification, a square protective ring 24 is provided on the mounting base 2 around the meter body 1. The protective ring 24 can be composed of multiple protective plates connected to each other to form a square ring structure, surrounding the meter body 1 in the middle. The protective plates are all made of fire-resistant and corrosion-resistant materials. A limiting groove 241 is provided at the bottom of the protective ring 24 facing the connecting line 12.

[0067] The interior of the protective ring 24 is hollow to form a protective cavity 242, which communicates with the interior of the adjustment chamber 21; a protective hole 243 is provided at the bottom of the protective ring 24, located on the inner wall of the limiting groove 241, and the protective hole 243 is arranged horizontally and points to the connecting line 12;

[0068] Specific workflow: Based on the specific workflow in Example 4, for electric energy meters installed in a poor environment, a protective ring 24 can be installed to protect the meter body 1. When moisture spreads on the wall and approaches the meter body 1, moisture usually needs to flow along the wall. The end of the protective ring 24 maintains a certain distance from the wall, making it difficult for moisture to cross. In this way, the protective ring 24 surrounding the meter body 1 effectively isolates moisture, prevents moisture from invading, and ensures that the inside of the meter body 1 is dry.

[0069] Moreover, because the outer shell of the watch body 1 can block external moisture, the intrusion of moisture needs to pass through the gaps in the outer shell of the watch body 1, especially through the gap between the connecting wire 12 at the bottom of the watch body 1 and the main body of the watch body 1; because the connection between the connecting wire 12 and the watch body 1 is too tight, it may cause greater wear on the surface of the connecting wire 12, thereby reducing the service life of the connecting wire 12; and if the gap is too large, external moisture may enter the interior of the watch body 1 along the connecting wire 12. In order to improve the barrier effect against external moisture and ensure the normal operation of the watch body 1,

[0070] The protective ring 24 is hollow inside to form a protective cavity 242. In this way, the air flowing into the protective cavity 242 through the adjustment chamber 21 of the protection tube 4 can be introduced into the protective cavity 242, and then flow out through the protective hole 243 located on the limiting groove 241, horizontally flushing the joint between the connecting line 12 and the meter body 1. In this way, when the humidity is high, the intrusion of external moisture is effectively isolated and the joint is dried and cleaned.

[0071] Furthermore, in densely populated areas such as factories or shopping malls, the safeguard tube 4 equipped on the electricity meter installed therein can be connected to the gas fire-retardant facility in the fire-fighting facility; in this way, when a fire occurs, the gas fire-retardant facility is activated, and the flame-retardant gas introduced can flow into the safeguard tube 4 and flow out through the adjustment holes 22 provided around the end of the mounting seat 2, and the flame-retardant gas flows along the wall in a direction away from the meter body 1, thereby effectively suppressing the flame spreading along the wall and protecting the meter body 1 in the middle; and the flame-retardant gas flowing into the adjustment chamber 21 can also flow into the protective ring 24, while reducing the heat of the protective ring 24, and flowing out from the protective hole 243 on the limiting groove 241, preventing the flame from approaching the meter body 1 along the connecting line 12; and when the flame causes the outer side of the protective ring 24 to rupture, the flame-retardant air flowing out of the protective cavity 242 can suppress the fire and prevent the flame from continuing to spread on the protective ring 24;

[0072] By effectively protecting the meter body 1 in a fire accident and ensuring the integrity of the meter body 1, the meter body 1 can transmit power consumption data in a timely manner, thereby assisting external rescue personnel in understanding the working conditions of internal electrical equipment, providing a strong basis for determining rescue and fire extinguishing plans, and also providing strong evidence for subsequent accident cause adjustment.

[0073] Example 6:

[0074] Based on the fifth embodiment, as shown in Figures 1-10 of the accompanying drawings, a mounting roller 25 is provided on the top of the protective ring 24. The end of the mounting roller 25 is connected to a driving device provided in the side wall of the protective ring 24. The driving device here can be a driving motor controlled by an intelligent processor. A protective sheet 251 is wrapped around the surface of the mounting roller 25. The protective sheet 251 is made of a fire-resistant elastic material.

[0075] The ends of the protective ring 24 are provided with closed grooves 244 , and the edges of the width sides of the protective sheet 251 are embedded in the closed grooves 244 and are slidably connected with the closed grooves 244 ;

[0076] Specific work flow: Based on the specific work flow in Example 5, when the humidity is high, in order to further block the intrusion of external humidity, the driving device is started, so that the driving device drives the installation roller 25 to rotate, and the rotating installation roller 25 releases the protective sheet 251 wound on the surface, and the end of the protective sheet 251 moves downward; and the ends of the protective sheet 251 on both sides contact the inner wall of the closed groove 244, slide downward along the surface of the closed groove 244 until it contacts the bottom of the protective ring 24, thereby covering the front of the watch body 1, and the protective sheet 251 can also effectively prevent moisture from entering the interior from the front opening of the protective ring 24 to corrode the watch body 1; and when the user goes out, the protective sheet 251 can also cooperate with the protective ring 24 to achieve surrounding coverage of the middle watch body 1 to prevent the intrusion of external dust;

[0077] When a fire occurs, the driving device is started to seal the front opening of the protective ring 24 with the protective sheet 251. The protective sheet 251 is made of fire-resistant and heat-insulating material, which can effectively prevent the invasion of external flames and smoke into the interior, and can also prevent the adverse effects of heat in the external high-temperature environment on the interior of the meter body 1, thereby ensuring the normal operation of the meter body 1.

[0078] Embodiment seven:

[0079] Based on the sixth embodiment, as shown in Figures 1-10 of the accompanying drawings, the protective sheet 251 is evenly provided with distribution grooves 252 on the surface facing away from the display screen 11. The distribution grooves 252 are arranged vertically. The top of the protective ring 24 is evenly provided with conductive holes 245 on the surface of the protective sheet 251 opposite the distribution grooves 252. The conductive holes 245 communicate with the protective cavity 242 inside the protective ring 24. The opening direction of the conductive holes 245 is inclined downward.

[0080] Specific work flow: Based on the specific work flow in Example 6, when moisture spreads upward, it first contacts the surface of the protective sheet 251 facing away from the display screen 11, so a conductive hole 245 is provided. When the dry airflow enters the internal protective cavity 242 of the protective ring 24, it flows out through the conductive hole 245, flushes the back of the protective sheet 251, and extends downward along the distribution groove 252 on the back of the protective sheet 251, so that the moisture contacting the surface of the protective sheet 251 is expelled under the flushing action, away from the protective sheet 251 and the internally protected watch body 1, thereby ensuring the normal working environment of the internal watch body 1.

[0081] Embodiment 8:

[0082] Based on the seventh embodiment, as shown in Figures 1-9 of the accompanying drawings, a fixing bar 246 is provided at the bottom of the protective ring 24 in the gap between the limiting grooves 241. The fixing bar 246 adopts an electromagnet structure, and the power-on activation of the fixing bar 246 is controlled by the intelligent processor.

[0083] An adsorption strip 253 is provided at the bottom of the protective sheet 251 facing the fixed strip 246. The adsorption strip 253 is made of metal, and rollers 254 are rotatably mounted on the edges of both sides of the adsorption strip 253. The outer ends of the rollers 254 are embedded in the vertical grooves 247 provided on the closed groove 244.

[0084] Drainage grooves 255 are evenly arranged on the adsorption strips 253. The drainage grooves 255 are arranged horizontally, and both ends of the drainage grooves 255 extend outwards.

[0085] Specific working process: Based on the specific working process in Example 7, when the driving device is started to move the protective sheet 251 downward, the adsorption strips 253 located on the bottom of the protective sheet 251 drive the rollers 254 at both ends to move downward, and the rollers 254 are embedded in the grooves 247 and roll in the grooves 247, thereby reducing the resistance encountered by the protective sheet 251 when sliding downward on the closed groove 244, so that the protective sheet 251 can move downward more smoothly; when the adsorption strips 253 at the bottom of the protective sheet 251 move downward to the bottom of the protective ring 24 and contact the fixing strips 246 at the bottom of the protective ring 24, the fixing strips 246 at the bottom of the protective ring 24 are started and energized; in this way, the fixing strips 246 generate magnetism and adsorb the contacting adsorption strips 253, thereby achieving the limiting and fixing effect on the protective sheet 251 and improving the sealing and protection effect on the internal watch body 1;

[0086] The adsorption strip 253 and the fixed strip 246 are at the same vertical height as the protective hole 243, so that the dry airflow flowing out of the protective hole 243 directly passes through the limiting groove 241 and contacts the adsorption strip 253. After contacting the drainage groove 255 on the adsorption strip 253, the dry airflow flows horizontally along the drainage groove 255, which on the one hand reduces the direct impact on the adsorption strip 253, and on the other hand, the horizontally flowing dry airflow flows in the drainage groove 255 in the gap between the adsorption strip 253 and the fixed strip 246, ensuring the dryness and cleanliness of the gap joint, further preventing external moisture from invading the interior through the gap between the adsorption strip 253 and the fixed strip 246, and further ensuring the normal use of the internal watch body 1.
