Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camera water meters, in particular to a non-magnetic sensing camera water meter. BACKGROUND

[0002] The non-magnetic sensing camera water meter (NB-IoT) integrates a non-magnetic sensing collector and a camera module, combines the non-magnetic sensing on-board collection technology and image recognition technology, realizes precise flow detection by using the anti-interference characteristics of non-magnetic sensing, provides intuitive reading credentials through image information, realizes real-time data transmission relying on the NB-IoT network, forms a solution of "double data collection + remote interaction", and thus realizes higher flow detection accuracy and resolution.

[0003] In the environment of basements, humid bathrooms, etc., when the temperature of the area where the water meter is located drops suddenly (such as night cooling, air conditioning or fan starting), water vapor in the air is easy to condense into water mist on the observation window of the water meter. This will cause the image of the counter photographed by the non-magnetic sensing camera water meter with camera recognition technology to be blurred, reduce the image quality, affect the accurate extraction of the reading by the camera module and related recognition algorithms, and thus interfere with the accurate acquisition of water consumption data.

Detailed Implementation

[0031] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0032] Example 1:

[0033] like Figures 1-8As shown, a non-magnetic sensor camera water meter includes a detection component 100, comprising a water meter body 101, a bottom pipe 102 disposed at the lower end of the water meter body 101, a camera module 103 disposed at the upper end of the water meter body 101, and a transmission module 104 disposed on the side of the water meter body 101. The water meter body 101 serves as the core metering unit, converting water flow signals into mechanical motion through impeller rotation. The non-magnetic sensor captures the number of impeller rotations and converts it into an electrical signal. A counter visually displays the water consumption, and a display window 201 provides a clear image acquisition field of view for the camera module 103. The bottom pipe 102 is divided into an inlet and an outlet, serving as a water flow channel, with the inlet leading to the water meter. The metered tap water drives the impeller inside the water meter body 101 to rotate, and the outlet delivers the metered water flow to the user's pipeline to ensure stable metering. The camera module 103 is installed on the upper part of the water meter body 101, with the lens of the camera module 103 facing the display window 201 of the counter. It has a built-in supplementary light and an image sensor and is connected to the control module via electrical connection. The camera module 103 can capture images of the digital module on the surface of the counter in real time. The supplementary light ensures uniform image brightness, and the image sensor converts the optical signal into a digital signal, which is transmitted to the transmission module 104 through the control module to provide a visual verification basis for the non-magnetic sensing data. The transmission module is fixed on the side of the water meter body 101 and has a built-in NB-IoT communication chip, antenna and battery. It is electrically connected to the camera module 103.

[0034] Tap water flows in from the inlet of the bottom pipe 102, driving the impeller inside the water meter body 101 to rotate and causing the counter to update the cumulative water consumption synchronously. When the impeller rotates, the non-magnetic sensor inside the water meter body 101 detects the number of rotations in real time, corrects the speed deviation through an algorithm, and converts it into accurate flow data, which is transmitted to the control module. At the same time, the camera module 103 at the top of the water meter body 101 is activated, and the lens captures the digital image of the counter through the display window 201. The supplementary light automatically adjusts the brightness. After the image is processed by the sensor, a digital signal is generated and sent to the control module. The control module cross-checks the non-magnetic sensor data and the camera image data. After confirming that they are consistent, the data is packaged and integrated. The integrated data is transmitted to the transmission module 104 on the side through a wire. The NB-IoT communication chip encrypts the data and sends it to the water supply company's server through the antenna, completing one data acquisition and upload.

[0035] By integrating the non-magnetic sensor collector with the camera module 103, and combining electromechanical conversion non-magnetic sensor onboard acquisition technology with image recognition technology, it can achieve accurate flow detection by utilizing the anti-interference characteristics of non-magnetic sensors, and provide intuitive reading evidence through image information. Furthermore, it relies on the NB-IoT network to achieve real-time data transmission, forming a "dual data acquisition + remote interaction" solution. This effectively makes up for the shortcomings of traditional technologies, such as weak anti-interference ability and insufficient accuracy, and meets the needs of water supply companies for accurate metering, efficient reading, real-time monitoring, and cost reduction.

[0036] like Figure 2 As shown, the drying component 200 includes a display window 201 disposed on the water meter body 101, a mounting collar 202 disposed on the display window 201, a scraping component 203 disposed on the mounting collar 202, a driving component 204 disposed on the scraping component 203, and a collecting component 205 disposed on the scraping component 203.

[0037] Among them, such as Figure 2 and Figure 3 As shown, the display window 201 is installed above the water meter body 101 as an observation port. It is generally made of transparent material and is mostly circular. The display window 201 serves as the observation interface for the counter of the water meter body 101. It can protect the mechanical and electronic components inside the water meter body 101 from external wind and moisture intrusion, and also provide a clear shooting field for the camera module 103 to ensure that the image recognition algorithm can accurately extract the counter numbers. Therefore, it is very important to keep the display window 201 clean and clear.

[0038] Specifically, such as Figure 3 and Figure 4 The mounting collar 202 is installed inside the water meter body 101 and is ring-shaped and fitted on the inner wall of the display window 201 of the water meter body 101. Its inner diameter is adapted to the edge of the display window 201. The mounting collar 202 serves as the basic support structure of the drying component 200 and provides a stable installation reference for the scraping component 203 and the drive component 204. At the same time, by tightly fitting with the display window 201, it forms a relatively closed space, reducing the direct entry of external humid air into the inside of the display window 201.

[0039] Furthermore, such as Figure 3 and Figure 4The scraping component 203 is located between the mounting collar 202 and the display window 201. There are two sets of scraping components 203, and the two sets of scraping components 203 are arranged symmetrically. The scraping component 203 is used to clean the display window 201 and keep the display window 201 clear. The drive component 204 is installed on the mounting collar 202 and is used to provide power for the scraping component 203 to perform cleaning. The collection component 205 is used to collect water droplets and impurities after the scraping component 203 has finished cleaning, so as to facilitate the subsequent use of the scraping component 203.

[0040] When water mist forms on the inner wall of the display window 201 due to temperature or humidity changes inside the water meter body 101, the drive component 204 provides power to the scraping component 203, driving the two sets of scraping components 203 to move along the slide rail of the mounting collar 202. The symmetrically distributed scraping components 203 move synchronously from both sides of the display window 201 towards the center, scraping away water mist, water droplets, and impurities. During the sliding process, water droplets and impurities fall into the collection component 205 directly below. Through the mechanical linkage and functional coordination of each component, the drying component 200 can automatically deal with the fogging problem of the display window 201, ensuring that the camera module 103 can always capture a clear counter image, providing stable support for the dual verification of non-magnetic sensing data and image recognition data.

[0041] like Figure 5 The scraping assembly 203 includes a scraping arc plate 203a disposed on the mounting collar 202, and an elastic scraper 203b disposed between the two scraping arc plates 203a; a scraper plate 203c is fixedly connected to the lower end of both the scraping arc plate 203a and the elastic scraper plate 203b, and the scraper plate 203c is in close contact with the inner wall of the display window 201.

[0042] Among them, there are two sets of scraping arc plates 203a, which are in the shape of a quarter circle to match the curvature of the circular display window 201. The outer side of the arc plates 203a is reserved with mounting slots for the elastic scraper 203b. The two sets of scraping arc plates 203a are stacked and distributed, with their central angles both being 90°. Together they can cover half of the circumference of the display window 201. It should be noted that the scraping arc plates 203a, as the main support structure of the scraping component 203, can fix the elastic scraper 203b through the slots to ensure that it does not fall off or shift during movement.

[0043] The two scraping arc plates 203a are connected by an elastic scraper 203b, which is located between the two scraping arc plates 203a. The elastic scraper 203b is made of elastic rubber and its middle part can deform slightly with the curvature of the display. Its surface is smooth and burr-free, which facilitates the scraping arc plate 203a to drive the elastic scraper 203b to move on the display window 201, thereby achieving the cleaning effect. It should be noted that the elastic scraper 203b uses the elastic properties of rubber to compensate for the slight curvature error that may exist in the display window 201, ensuring that the scraper plate 203c is always in close contact with the inner wall of the display window 201. Driven by the scraping arc plate 203a, it wipes the middle area of ​​the display window 201, filling the cleaning blind spot between the two sets of scraping arc plates 203a.

[0044] To ensure the cleaning effect of the scraping component 203, a scraper plate 203c is installed below the scraping arc plate 203a and the elastic scraper plate 203b. This allows the elastic scraper plate 203b and the scraping arc plate 203a to clean more thoroughly. It should be noted that the edge of the scraper plate 203c is polished into a wedge shape. The scraper plate 203c is fixed to the lower end face of the scraping arc plate 203a and the elastic scraper plate 203b, respectively, and fits against the inner wall of the display window 201. As a direct cleaning component, the wedge-shaped edge of the scraper plate 203c can efficiently scrape away water mist, condensed water droplets, and extremely small impurities from the inner wall of the display window 201. Moreover, the scraper plate 203c is made of silicone, which combines softness and wear resistance, ensuring a clean finish without damaging the surface of the display window 201.

[0045] When cleaning of the display window 201 is required, the drive assembly 204 provides power to the scraping arc plates 203a, driving the two sets of scraping arc plates 203a to perform synchronous counter-clockwise circular motions along the slide rails on the inner wall of the mounting collar 202. As the scraping arc plates 203a move, the intermediate elastic scraper 203b naturally deforms with the curvature of the display window 201, ensuring no cleaning gap between the scraping arc plates 203a and the elastic scraper 203b. Simultaneously, the scraper blade 203c, fixed to the upper end of all three, moves with the overall structure, its wedge-shaped cutting edge sliding tightly against the inner wall of the display window 201 to physically scrape away water mist and impurities in the contact area. The scraper blade 203c below the scraping arc plates 203a is responsible for cleaning the display window 201. The scraper blade 203c below the elastic scraper blade 203b is responsible for the central area, forming a full-coverage cleaning range without dead angles. During the cleaning process, the slight deformation of the elastic scraper blade 203b can adapt to the surface of the display window 201, avoiding water mist residue due to local gaps. The silicone material of the scraper blade 203c will produce slight deformation when scraping, enhancing the adhesion to the glass surface and improving the efficiency of water droplet removal. The scraped water droplets and impurities slide down the inner wall of the display window 201 under the action of gravity and are finally received by the collection component 205 at the bottom, completing one cleaning cycle. After cleaning is completed, the drive component 204 reverses, driving the scraping component 203 back to the initial position, waiting for the next start.

[0046] like Figure 4 and Figure 5 The drive assembly 204 includes a drive rod 204a disposed within the mounting collar 202, a drive wheel 204b disposed on the drive rod 204a, a drive slide plate 204c disposed on the drive wheel 204b, a connector 204d disposed on the drive slide plate 204c, and a power component 204e disposed on the drive rod 204a; the drive rod 204a is rotatably connected to the mounting collar 202, and the drive wheel 204b is engaged with the drive slide plate 204c.

[0047] Specifically, there are two sets of drive components 204, each corresponding to the scraping component 203. The drive rod 204a is located inside the mounting collar 202, and the drive rod 204a and the mounting collar 202 are rotatably connected. The drive wheel 204b serves as the core shaft for power transmission, receiving the torque output from the power component 204e and transmitting it to the drive wheel 204b. This ensures that the friction is low and the stability is high during rotation, allowing it to withstand continuous bidirectional rotation.

[0048] The drive wheel 204b is sleeved on the drive rod 204a, and the drive wheel 204b and the drive rod 204a are fixedly connected. The two sets of drive wheels 204b are fixed on the two drive rods 204a respectively, with opposite tooth directions. The main function of the drive wheel 204b is to convert the rotational motion of the drive rod 204a into the arc trajectory of the drive slide plate 204c, and transmit power through gear meshing to ensure stable power output without slippage.

[0049] like Figure 4 There are two sets of drive slide plates 204c, and each drive slide plate 204c is provided with a rack opening that meshes with the drive wheel 204b. The drive slide plate 204c is semi-arc, and its curvature is consistent with the inner wall of the display window 201. The inner side of the drive slide plate 204c is provided with a rack opening that matches the drive wheel 204b. The two drive slide plates 204c are located on the inner and outer sides of the drive wheel 204b, respectively, and the racks are in opposite directions. Both drive slide plates 204c are semi-arc. When the drive wheel 204b rotates, it drives the two drive slide plates 204c to move along the inner diameter of the mounting collar 202, thereby providing power to the scraping component 203. Driven by the drive wheel 204b, the drive slide plate 204c slides in an arc along the inner wall of the mounting collar 202, converting the rotational power of the gear into arc displacement.

[0050] The connector 204d includes a connecting rod 204d-1 disposed on the drive slide plate 204c, and a connecting plate 204d-2 disposed on the connecting rod 204d-1; wherein the connecting rod 204d-1 and the drive slide plate 204c are fixedly connected, and the connecting rod 204d-1 and the connecting plate 204d-2 are rotatably connected.

[0051] It should be noted that the connecting rod 204d-1, as the intermediate shaft for power transmission, has a fixed end that is fixedly connected to the drive slide plate 204c, and a rotating end that is rotatably connected to the connecting plate 204d-2 through a bearing. This allows the connecting plate 204d-2 to rotate freely around the axis of the connecting rod 204d-1, compensating for the deviation in the motion trajectory between the drive slide plate 204c and the scraping assembly 203. The connecting component for power transmission of the connecting plate 204d-2 can convert the arc-shaped motion of the drive slide plate 204c into the synchronous motion of the scraping assembly 203, avoiding stress concentration caused by the fixed connection.

[0052] The power component 204e includes a transmission wheel 204e-1 sleeved on the drive rod 204a, a transmission belt 204e-2 mounted on the transmission wheel, a transmission wheel 204e-3 mounted on the transmission belt 204e-2, and a transmission motor 204e-4 mounted on the transmission wheel 204e-3.

[0053] Among them, transmission wheel 204e-1 is sleeved on drive rod 204a, and there is a fixed connection between transmission wheel 204e-1 and drive rod 204a. Transmission wheel 204e-1, as the terminal wheel of force transmission, converts the torsion transmitted by transmission belt 204e-2 into the rotational motion of drive rod 204a through the fixed connection with drive rod 204a, ensuring that the power is transmitted to drive assembly 204 without slippage; transmission belt 204e-2 is sleeved on transmission wheel 204e-1 and transmission wheel 204e-3. It serves as a flexible transmission component connecting transmission wheel 1 204e-1 and transmission wheel 204e-3; transmission wheel 204e-3 is installed on the output end of transmission motor 204e-4, and as the power output wheel, it can transmit the rotational power of transmission motor 204e-4 to transmission wheel 1 204e-1 through transmission belt 204e-2, thereby providing power for the rotation of drive rod 204a. Transmission motor 204e-4 serves as the power source. Transmission motor 204e-4 is a micro motor that can perform reciprocating motion.

[0054] When the humidity sensor inside the display window 201 detects excessive humidity, the control module sends a start signal to the drive motor 204e-4. At this time, both drive motors 204e-4 are powered on and start simultaneously. The operation of the drive motors 204e-4 drives the second drive wheel 204e-3 to rotate, and transmits the power to the first drive wheel 204e-1 through the transmission belt 204e-2, which in turn drives the drive rod 204a to start rotating. When the drive rod 204a rotates, the drive wheel 204b fixed on it rotates synchronously. Since the teeth of the two sets of drive wheels 204b are opposite and mesh with the racks of the inner and outer drive slide plates 204c respectively, they will drive the two sets of drive slide plates 204c to slide in opposite arcs along the mounting collar 202. During the sliding of the plate 204c, power is transmitted to the scraping assembly 203 through the connector 204d. The connecting rod 204d-1 moves synchronously with the slide plate. The connecting plate 204d-2 compensates for the movement deviation through the bearing structure, driving the scraping arc plate 203a, the elastic scraper 203b, and the scraper blade 203c to slide close to the inner wall of the display window 201, completing the cleaning of water mist and impurities. When the drive slide plate 204c slides to the end of its stroke, the sensor triggers a signal, and the control module sends a signal to the drive motor 204e-4. The drive motor 204e-4 reverses and drives the scraping arc plate 203a, the elastic scraper 203b, and the scraper blade 203c to reset through the same transmission link, returning to the initial position for subsequent use.

[0055] like Figures 6-8The collection component 205 includes a first collection groove 205a mounted on the scraping arc plate 203a, a second collection groove 205b disposed on the elastic scraper 203b, a storage cavity 205c disposed in the mounting collar 202, an adsorption element 205e disposed in the storage cavity 205c, and a trigger element 205d disposed between the first collection groove 205a and the storage cavity 205c.

[0056] The first collection chute 205a on the scraping arc plate 203a is inclined. The high end of the first collection chute 205a is connected to the second collection chute 205b. The bottom end of the first collection chute 205a is close to the storage cavity 205c. The gravity component generated by the inclined angle guides the collected liquid and impurities along the chute towards the storage cavity 205c. The edge of the chute is designed with a high baffle to prevent liquid from overflowing. The second collection chute 205b is designed with a slope that is high in the middle and low at both ends, with a slope of 3-5 degrees. This design makes it convenient for water and impurities to slide down to the end of the first collection chute 205a and the connection point with the storage cavity 205c, thus facilitating subsequent processing.

[0057] like Figure 8 The adsorption element 205e is located inside the storage cavity 205c and is usually made of sponge material. It quickly adsorbs liquid through capillary action to ensure that the liquid does not leave any residue or flow back. Solid impurities are trapped by the surface of the sponge. Because the sponge has a certain elasticity, it can expand with adsorption to fix the impurities on the surface and prevent them from falling off again.

[0058] like Figure 7 The trigger element 205d includes an abutment rod 205d-1 disposed in the storage cavity 205c, a dripping through hole 205d-2 disposed at the end of the collection chute 205a, an abutment protrusion 205d-3 disposed on the dripping through hole 205d-2, and the abutment protrusion 205d-3 and the dripping through hole 205d-2 being connected by a connecting spring.

[0059] The drip through hole 205d-2 is located corresponding to the position of the contact rod 205d-1 of the storage cavity 205c. The contact protrusion 205d-3 is adapted to the contact rod 205d-1, and the connecting spring is a torsion spring.

[0060] It should be noted that when the scraping assembly 203 slides to the end of its stroke, the trigger 205d begins to move. The abutment rod 205d-1 in the storage cavity 205c contacts the abutment protrusion 205d-3 at the lower end of the collection chute 205a. As the scraping arc plate 203a continues to move, the abutment rod 205d-1 pushes the abutment protrusion 205d-3 to compress the connecting spring, causing a gap to be created between the abutment block and the dripping hole 205d-2. At this time, the liquid and impurities temporarily stored in the collection chute flow into the storage cavity 205c through the dripping hole 205d-2 under the action of gravity.

[0061] When the scraping arc plate 203a drives the collection chute 205a to the storage chamber 205c, the contact rod 205d-1 contacts the contact protrusion 205d-3. As the movement continues, the liquid enters the storage chamber 205c through the drip hole 205d-2, thus completing the collection. After collection, the collection chute 205a moves away from the storage chamber 205c along with the scraping arc plate 203a, and the contact rod 205d-1 and the contact protrusion 205d-3 disengage. The connecting spring elastically resets, pushing the contact protrusion 205d-3 to cover the drip hole 205d-2 again, achieving a seal and preventing moisture in the storage chamber 205c from back-permeating into the display window 201 through the drip hole 205d-2. Furthermore, during the reset process, due to the tilt angle design, the residual liquid in the collection chute 205a and collection chute 205b can gather again towards the lower end, and the collection process can be repeated during the next cleaning.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
