Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, specifically to a smart meter integrating an AI analysis and control module. Background Technology

[0002] Smart meters are the core sensing terminals of modern smart grids. They not only possess high-precision energy metering capabilities but also integrate advanced Internet of Things (IoT), communication, and microelectronics technologies. Unlike traditional meters, smart meters support bidirectional data transmission, collecting real-time electricity consumption data such as voltage, current, and power, and automatically uploading this data to the power supply system via the network. This enables "minute-level" or even "second-level" electricity monitoring, completely eliminating the need for manual meter reading. They support time-of-use pricing, remote power on / off control, and allow users to check their electricity consumption anytime via a mobile app, aiding in scientific electricity use. Simultaneously, their powerful anti-theft monitoring function effectively ensures electricity safety. As a bridge connecting users and the power grid, smart meters significantly improve power operation efficiency, reduce management costs, and are a crucial infrastructure for realizing energy digitalization, promoting energy conservation and emission reduction, and building smart cities.

[0003] Smart meters rely on internal circuit boards for continuous operation. Their electronic components generate heat during metering and communication, so the casing typically has ventilation holes (or slots) to dissipate this heat. To prevent insects or large particles from entering, these holes and slots are fitted with dust filters. However, this is a physical filtration method: to ensure airflow, the ventilation holes must remain open, meaning the pore size and mesh cannot be perfectly dense. Over long-term operation, fine dust suspended in the air slowly enters the meter's interior with the airflow. While the dust filters block most fibers and coarse particles, extremely fine dust particles gradually penetrate and accumulate on the circuit board surface. This dust accumulation forms a heat insulation layer, hindering heat dissipation and causing localized temperature increases, affecting metering accuracy and lifespan. In humid environments, the accumulated dust can also absorb moisture, reducing circuit insulation performance and even causing short circuits. Summary of the Invention

[0004] The purpose of this invention is to provide a smart meter that integrates an AI analysis and control module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart meter integrating an AI analysis and control module, comprising a meter housing, and further comprising: Two sets of intermittently opening air intake mechanisms are provided on the side of the meter housing. The inlet end of the intermittently opening air intake mechanism opens during the air intake process. An intermittently opening air outlet mechanism is located on the other side of the meter housing and its position corresponds to that of the intermittently opening air inlet mechanism. The intermittently opening air outlet mechanism opens when the intermittently opening air inlet mechanism is working. The circuit board body has a temperature detection module and a control module on its surface, which are located inside the meter housing. A copper plate is provided on the back of the circuit board body.

[0006] Preferably, the intermittently opening air intake mechanism includes: There are two air inlets, which are connected and installed on the side of the meter housing; An air outlet grille is provided at the outlet end of the air inlet duct; The first dustproof net is fixed to the inlet end of the air inlet duct; The fan body is bolted to the middle part of the air inlet duct; An intermittent opening and closing component is located between the first dustproof mesh and the fan body. When the fan body is turned on, the intermittent opening and closing component is in the open state. The transmission component transmits the motor power of the fan body to the air outlet grille.

[0007] Preferably, the intermittent opening and closing assembly consists of a fixed plate, a blocking plate, and an impact block. The number of fixed plates is several and they are bolted to the inside of the air inlet duct. The blocking plate and the fixed plate are hinged to each other by a hinge. The impact block is fixed to the surface of the fixed plate.

[0008] Preferably, the number of impact blocks is several and they are made of rubber.

[0009] Preferably, the transmission assembly includes: The sleeve is bolted to the fan body; The first transmission column is connected to the fan blade shaft of the fan body; Two sets of vertical plates are bolted to the inner wall of the sleeve. The second transmission column passes through the vertical plate and is rotatably connected to the point where it passes through. The second transmission column is connected to the first transmission column through a gear transmission. A fixing seat is bolted to the other side inside the sleeve; The third transmission column is rotatably connected to the fixed base, and the end of the third transmission column is bolted to the air outlet grille. The third transmission column is connected to the second transmission column through gear transmission.

[0010] Preferably, the first transmission column is connected to the second transmission column by a small gear driving a large gear, and the second transmission column is connected to the third transmission column by a small gear driving a large gear.

[0011] Preferably, the intermittently opening air outlet mechanism includes: The side grooves are in two sets and are located on the side of the meter housing away from the air inlet duct; The second dustproof net is bolted to the inside of the side groove; A baffle is rotatably connected to the surface of the meter housing and is located above the side groove.

[0012] Preferably, the baffle is made of plastic and its length and width are greater than the length and width of the side groove.

[0013] Preferably, the air outlet grille and the sealing plate are made of plastic.

[0014] Preferably, silicone grease is applied between the circuit board body and the copper plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The temperature detection module on the circuit board body in this invention monitors the internal temperature in real time and activates the fan body for heat dissipation only when the temperature exceeds a preset value. When the fan is running, the airflow pushes open the sealing plate connected by hinges, making the internal channel of the air inlet unobstructed; at the same time, the airflow blows the lightweight plastic baffle on the other side, opening the side groove to form convection. When the fan stops, the sealing plate automatically falls back under the action of gravity, sealing the gap between the fixed plates, and the baffle also closes again to cover the side groove. This working mode of opening on demand and closing when not in use keeps the meter housing relatively sealed during non-heat dissipation periods, greatly reducing the chance of external suspended dust intrusion, inhibiting the accumulation of dust on the circuit board from the source, and ensuring electrical insulation performance and long-term operational reliability.

[0016] 2. When the fan body of the present invention starts, its fan blade shaft drives the first transmission column to rotate. After two stages of gear reduction, it drives the third transmission column to rotate slowly, which in turn drives the air outlet grille to rotate. This allows the forced cooling airflow to be blown evenly onto the copper plate on the back of the circuit board body. Combined with the applied silicone grease, it significantly enhances the heat conduction and convection heat transfer efficiency. Moreover, during the opening and closing of the sealing plate, it will hit the rubber impact block. The resulting vibration is transmitted to the first dustproof net, which can effectively shake off some of the dust attached to the net surface, achieve a preliminary self-cleaning function, and extend the maintenance cycle.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 A smart meter integrating an AI analysis and control module includes a meter housing 100, an intermittently opening air intake mechanism 200, an intermittently opening air outlet mechanism 400, and a circuit board body 300. Two sets of intermittently opening air intake mechanisms 200 are located on the side of the meter housing 100, with their inlets opening during air intake. The intermittently opening air outlet mechanism 400 is located on the other side of the meter housing 100, corresponding to the intermittently opening air intake mechanism 200, and opens when the intermittently opening air intake mechanism 200 is in operation. The circuit board body 300 has a temperature detection module and a control module on its surface, located inside the meter housing 100. A copper plate 310 is provided on the back of the circuit board body 300, and silicone grease is applied between the circuit board body 300 and the copper plate 310 for heat transfer.

[0021] Specifically, the intermittently openable air intake mechanism 200 includes an air intake duct 210, an air outlet grille 220, a first dustproof net 230, a fan body 240, and an intermittent opening and closing assembly 250. There are two air intake ducts 210, which are connected and set on the side of the meter housing 100. The air outlet grille 220 is set at the outlet end of the air intake duct 210. The first dustproof net 230 is fixed at the inlet end of the air intake duct 210. The fan body 240 is bolted to the middle part of the air intake duct 210. The intermittent opening and closing assembly 250 is located between the first dustproof net 230 and the fan body 240. When the fan body 240 is open, the intermittent opening and closing assembly 250 is in the open state. The transmission assembly 260 transmits the motor power of the fan body 240 to the air outlet grille 220. The air outlet grille 220 and the sealing plate 252 are made of plastic, making the air outlet grille 220 and the sealing plate 252 lighter.

[0022] Furthermore, the intermittent opening and closing assembly 250 consists of a fixed plate 251, a blocking plate 252, and an impact block 253. There are several fixed plates 251 and they are bolted to the inside of the air inlet duct 210. The blocking plate 252 and the fixed plate 251 are hinged to each other by a hinge. The impact block 253 is fixed to the surface of the fixed plate 251. There are several impact blocks 253 and they are made of rubber, so they can make elastic contact with the first dustproof net 230.

[0023] The transmission assembly 260 includes a sleeve 261, a first transmission column 262, a vertical plate 264, a second transmission column 263, a fixed seat 266, and a third transmission column 265. The sleeve 261 is bolted to the fan body 240. The first transmission column 262 is connected to the fan blade shaft of the fan body 240. There are two sets of vertical plates 264, which are bolted to the inner wall of the sleeve 261. The second transmission column 263 passes through the vertical plate 264 and is rotatably connected to it at the point of penetration. The second transmission column 263 is connected to the first transmission column 262 via gear transmission. The fixed seat 266 is bolted to the other side inside the sleeve 261. The third transmission column 265 is rotatably connected to the fixed base 266. The end of the third transmission column 265 is bolted to the air outlet grille 220. The third transmission column 265 is connected to the second transmission column 263 through gear transmission. The third transmission column 265 enables the air outlet grille 220 to rotate. The first transmission column 262 drives the large gear through a small gear and is connected to the second transmission column 263 through transmission. The first transmission column 262 and the second transmission column 263 achieve speed reduction. The second transmission column 263 drives the large gear through a small gear and is connected to the third transmission column 265 through transmission. The second transmission column 263 and the third transmission column 265 achieve speed reduction.

[0024] The intermittently openable air outlet mechanism 400 includes a side channel 410, a second dustproof net 420, and a baffle 430. There are two sets of side channels 410, which are opened on the side of the meter housing 100 away from the air inlet duct 210. The second dustproof net 420 is bolted to the inside of the side channel 410. The baffle 430 is rotatably connected to the surface of the meter housing 100 and is located above the side channel 410. The baffle 430 is made of plastic and its length and width are greater than the length and width of the side channel 410, so that the baffle 430 can completely cover the side channel 410.

[0025] When the fan body 240 is not running, the sealing plate 252 seals the gap between the fixing plates 251, and the baffle 430 seals the side groove 410 to prevent fine dust from entering due to prolonged openness. During operation, the meter operates, and the temperature of its circuit board body 300 rises. The temperature sensing module on the surface of the circuit board body 300 detects the temperature rise exceeding a preset value, and then the control module controls the fan body 240 to turn on. The heat generated by the circuit board body 300 can be transferred to the copper plate 310. The opening of the fan body 240 allows external air to enter through the first dust filter 230, which intercepts dust. The air entering the air inlet duct 210 pushes open the sealing plate 252, opening the gap between the fixing plates 251. Simultaneously, the fan blade shaft of the fan body 240 drives the first transmission column 262 to rotate. The first transmission column 262 drives the second transmission column 263 to rotate through gears, achieving initial deceleration. The second transmission column 263 drives the third transmission column 265 to rotate through gears, achieving further deceleration, which in turn drives the air outlet grille 220 to rotate, so that the air discharged from the fan body 240 is evenly blown into the inside of the meter. The air passes through the copper plate 310, carrying away heat, and then blows open the baffle 430 on the other side to discharge. After the fan body 240 stops rotating, the sealing plate 252 closes again under the action of gravity, and the baffle 430 also closes again. Meanwhile, the impact block 253 impacts the first dustproof net 230, generating vibration, causing some of the dust hanging on the surface of the first dustproof net 230 to fall off.

[0026] The control module on this circuit board employs an industrial-grade multi-core processor and a secure embedded operating system, along with a built-in large-capacity memory. Leveraging its powerful concurrent processing capabilities, it can efficiently acquire data from multiple targets, fully supporting basic functions such as power metering, AC analog signal acquisition, status signal acquisition, equipment operation monitoring, clock synchronization, event logging, and reporting. Furthermore, the terminal utilizes an app-based container deployment architecture, allowing for the interchangeability and functional expansion of similar business applications developed by different vendors. This enables flexible adaptation to various complex application scenarios, including power consumption information collection, power quality analysis, distributed power management, orderly charging control, user energy efficiency monitoring, and station environment monitoring.
