[0030] The following describes in detail the smart water meter provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] Example 1

[0032] Figure 1 This is a schematic diagram of the structure of the smart water meter device provided in the embodiment of the present application. Figure 1 As shown, the smart water meter includes:

[0033] Base table 101, used to collect water consumption data;

[0034] The control module 102 is provided inside the base meter and is used to process the water consumption data collected by the base meter to obtain water consumption data to be sent;

[0035] The communication module 103 is connected to the base meter in a detachable manner. After being connected to the base meter, it is connected to the control module through a preset optical signal communication pipeline, and is used to receive the water usage data to be sent transmitted by the control module, and send the water usage data to be sent to the water resource management platform via wireless transmission.

[0036] Base meter 101 can be the portion of a smart water meter used to collect water usage data. Specifically, water usage data can be collected by connecting the base meter to the water pipe to be measured, for example, the water inlet pipe at a user's residence. When a user uses water, water flows through the water inlet pipe, first through the smart water meter, and then to the user's residence. During this process, the base meter housing of the smart water meter is fixed, with a fixed internal volume, while the water is fluid. This water flow drives the impeller inside the housing to rotate. Each time the impeller rotates, a constant volume of water flows through. Therefore, a counter connected to the impeller in the base meter simply counts the number of impeller rotations and multiplies this number by the constant volume of the housing to obtain the total water volume that has flowed through, i.e., the user's water usage data.

[0037] The control module 102 can be a hardware device with sufficient computing and storage capabilities, such as a single-chip microcomputer or microprocessor. Specifically, the control module can be located in a designated circuit within the base meter. The circuit acquires water usage data collected by the counter, processes the water usage data according to a pre-loaded algorithm, and transmits the water usage data to the communication module via the circuit in the form of an optical signal. The control module also sends a transmission instruction to the communication module to control the communication module to report the water usage data to the water resource management platform. The water usage data can be processed by the control module acquiring the number of impeller rotations collected by the counter in the base meter, calculating the product of the number of rotations and the housing, and associating the calculated result with the current collection time to obtain the water usage data. The water usage data is then encoded and converted into a signal that can be transmitted.

[0038] The water resource management platform can be used to centrally manage all smart water meters and store the water usage data reported by each smart water meter. Staff can use the water resource management platform to query and obtain the operating status and water usage data of smart water meters.

[0039] The communication module 103 can be an Internet of Things module. Through the radio frequency chip and antenna in the communication module, the water usage data to be sent is modulated onto a specific wireless frequency band for transmission. In addition, the communication module can also receive instructions from the water resource management platform, demodulate and pass the data to the control module, and the control module responds to the instructions of the water resource management platform. The communication module and the base meter are connected in a detachable manner, such as a bayonet structure, a plug-in structure, or a magnetic connection. While the communication module is connected to the base meter, the communication module and the control module are connected through a pre-set optical signal communication pipeline, wherein the optical signal communication pipeline is used to support signal transmission between the communication module and the control module.

[0040] An optical signal communication conduit can be a communication cable consisting of two or more glass or plastic optical fiber cores, wherein the optical fiber core is located in a protective coating and covered by a plastic outer sleeve. Optical signals (usually infrared rays) can propagate quickly along the optical fiber core to achieve communication between devices.

[0041] Based on the above solution, optionally, the communication module and the base meter are connected via a plug-in structure, a pin is provided on the communication module, and a socket is provided on the base meter, wherein the positions of the pin and the socket correspond one to one.

[0042] The communication module and the base meter can be connected via a plug-in connection. Specifically, the communication module is provided with at least two pins in the contact area between the communication module and the base meter. The length of the pins is determined to ensure that they can be fixed in the sockets of the base meter without damaging the internal structure of the base meter. The base meter has the same number of sockets as pins, and they are aligned with the pins. When connecting the communication module to the base meter, the size and shape of the sockets can match the pins, thereby ensuring that the communication module can be fixed to the base meter without shaking or detaching.

[0043] Based on the above solution, optionally, the jack is provided with an anti-misinsertion structure, and the pin and the jack are set to an asymmetric shape, and the pin matches the jack only when the communication module is inserted into the base table in the correct direction.

[0044] The jack can be equipped with an anti-misinsertion structure by designing the pins and jack into asymmetrical shapes, such as triangles, trapezoids, or specific polygons. Only when the communication module is inserted into the base meter in the correct direction will the pins and jack shapes match, allowing the pins to be inserted smoothly into the jack. If inserted in the wrong direction, the pins will not be fully inserted into the jack due to the mismatched shapes, thus preventing the communication module from being inserted upside down, which will affect the signal transmission quality between the communication module and the control module.

[0045] Based on the above solution, optionally, the communication module is provided with a locking piece, and the base meter is provided with a locking groove. After the communication module is connected to the base meter, the locking piece is rotated to penetrate into the locking groove.

[0046] The locking piece can be set on the housing of the communication module, one end of which is a fixed rod fixed on the housing of the communication module, and the other end is a metal rod. The cross-sectional radius of the metal rod gradually increases from front to back, and the end of the metal rod has a connecting rod. The metal ring at the end of the connecting rod can rotate around the fixed rod.

[0047] The locking groove can be an arched metal ring fixed to the base meter housing. After the communication module is tightly connected to the base meter through the plug-in structure, the metal rod in the locking piece is rotated to rotate around the fixed rod and penetrate into the locking groove until the metal rod can no longer be pushed into the locking groove. At this time, the metal rod can fill the arched metal ring. Since the arched metal ring is fixed to the base meter housing, the communication module cannot move up and down relative to the base meter. Due to the tight connection between the pin and the socket, the communication module cannot move in the plane relative to the base meter. At this point, the communication module can be firmly fixed to the base meter. If the communication module needs to be disassembled, it is necessary to rotate the locking piece in the opposite direction to make it leave the locking groove, and then pull the communication module upward.

[0048] In this solution, the smart water meter includes: a base meter for collecting water usage data; a control module, located within the base meter, for processing the collected water usage data to generate the to-be-transmitted water usage data; and a communication module, detachably connected to the base meter. Once connected to the base meter, the communication module connects to the control module via a pre-set optical signal communication channel, receiving the to-be-transmitted water usage data transmitted by the control module and wirelessly transmitting the to-be-transmitted water usage data to a water resource management platform. The detachable design of the communication module from the base meter facilitates separate replacement of the communication module in the event of a malfunction, significantly reducing maintenance costs and operational complexity while improving maintenance efficiency.

[0049] Example 2

[0050] Figure 2 Schematic diagram of the communication module and control module structure of the smart water meter provided in the embodiment of the present application. Figure 2 As shown, the communication module is provided with at least two connection terminals, the base meter is provided with at least two reserved ports, and the connection terminals are aligned with the reserved ports;

[0051] The at least two reserved ports are connected to the signal output end of the control module through leads.

[0052] The terminal can be a wire jack pre-reserved in the communication module for connecting external signal lines. When the communication module needs to be connected to an external device, the signal line is inserted into the terminal, and the screw is turned to tighten the connection. The signal line can then be connected to the circuit inside the communication module.

[0053] The reserved port can be a wiring port reserved in the base meter that can be directly connected to the control module. Within the base meter, the port used by the control module for signal exchange with the outside world is connected to the reserved port of the base meter via a lead. Furthermore, while the communication module is connected to the base meter, a signal line is used to connect the wiring terminal to the reserved port. The control module can then send water usage data to the communication module via the signal output terminal, lead, reserved port, and wiring port.

[0054] Based on the above solution, optionally, the optical signal communication pipeline is an optical fiber channel, which is used to transmit the water consumption data to be sent in the form of an optical signal;

[0055] The communication module is provided with an infrared emitting tube and an infrared receiving tube, and is respectively connected to at least two terminals; the control module is provided with an infrared receiving tube and an infrared emitting tube, and is respectively connected to at least two reserved ports;

[0056] The advantage of this arrangement of the present solution is that the connection between the communication module and the control module can be set to a detachable mode through the wiring terminals, reserved ports and optical signal communication pipes, thereby reducing the impact of the replacement of the communication module on signal transmission, improving the maintenance efficiency of the communication module and reducing maintenance costs.

[0057] Among them, after the wiring terminal is docked with the reserved port, the infrared emitting tube provided in the communication module is docked with the infrared receiving tube provided in the control module; and the infrared receiving tube provided in the communication module is docked with the infrared emitting tube provided in the control module.

[0058] The method for transmitting the water usage data to be sent is to install the communication module on the base meter and connect the connection terminal of the communication module to the reserved port of the base meter through the optical signal communication pipeline. After the control module obtains the water usage data to be sent, it converts it into a signal according to the communication protocol and sends it through the reserved port in the form of an optical signal, so that the optical signal can be transmitted along the optical signal communication pipeline to the connection terminal and then received by the communication module.

[0059] An infrared emitting tube is a light-emitting device that converts electrical energy directly into near-infrared light (invisible light) and radiates it. Infrared emitting tubes are made of materials with high infrared radiation efficiency, such as gallium arsenide and gallium aluminum arsenide. When a forward bias current is injected into the PN junction, it excites and generates infrared light. Its spectral power distribution has a central wavelength between 830 and 950 nanometers.

[0060] An infrared receiver tube is a semiconductor device that converts optical signals (primarily infrared light) into electrical signals. The core component of an infrared receiver tube is a PN junction made of a special material. When operating under reverse voltage conditions and without light, the reverse current is very small, known as dark current. When exposed to infrared light, the energy of the photons is transferred to covalently bound electrons, generating photogenerated carriers. These carriers engage in drift motion under the influence of the reverse voltage, significantly increasing the reverse current. Greater light intensity increases the reverse current. If a load is connected to the external circuit, the load will receive an electrical signal that varies with the light intensity.

[0061] In this solution, among the at least two wiring terminals of the communication module, at least one wiring terminal is connected to the infrared emitting tube, and at least one wiring terminal is connected to the infrared receiving tube. At the same time, among the at least two reserved ports of the base meter, at least one reserved port is connected to the infrared emitting tube of the control module inside the base meter, and at least one reserved port is connected to the infrared receiving tube of the control module inside the base meter.

[0062] When the connection terminal is docked with the reserved port, the connection terminal connected to the infrared emitting tube is connected to the reserved port connected to the infrared receiving tube, and the connection terminal connected to the infrared receiving tube is connected to the reserved port connected to the infrared emitting tube, respectively, using an optical fiber channel. At this time, if the control module sends water consumption data to the communication module, the water consumption data can be converted into an electrical signal and sent to the infrared emitting tube. The infrared emitting tube converts the electrical signal into an optical signal and sends it to the reserved port. The optical signal is then transmitted along the optical fiber channel to the connection terminal and captured by the infrared receiving tube connected to the connection terminal. The infrared receiving tube can then convert the received optical signal back into an electrical signal that can be interpreted by the communication module.

[0063] Correspondingly, when the communication module sends a control command received from the water resource management platform to the control module, it can send the control command to the infrared emitting diode, which converts the electrical signal into an optical signal and sends it to the wiring terminal. The signal is then transmitted along the optical fiber channel to the infrared receiving diode connected to the reserved port, where it is captured by the infrared receiving diode. The infrared receiving diode then converts the received optical signal back into an electrical signal that can be interpreted by the control module. This process enables information exchange between the communication module and the control module.

[0064] The advantage of this arrangement is that water usage data can be transmitted in the form of optical signals through infrared transmitting tubes and infrared receiving tubes, which is beneficial to increase the speed and accuracy of signal transmission and reduce the power consumption of smart water meters.

[0065] On the basis of the above solution, optionally, the optical fiber channel includes an outer sheath and an optical fiber cable, wherein the outer sheath is an insulating sheath that can be covered and bonded, and is tightly attached to the surface of the optical fiber cable.

[0066] The outer protective sheath can be an insulating sheath made of a rubber compound, which has a certain adhesiveness and can cover the optical fiber cable. The outer sheath is tightly attached to the outer surface of the optical fiber cable, so that the outer sheath completely wraps the optical fiber cable. During the operation of the optical fiber cable, it can prevent water leakage from the water pipe and cause aging of the optical fiber cable, which is beneficial to extending the service life of the optical fiber cable.

[0067] The advantage of this arrangement of the present invention is that an outer protective sheath can be added to the optical fiber cable, which significantly improves the wear resistance and waterproof ability of the optical fiber cable during use, thereby increasing the service life of the optical fiber cable.

[0068] On the basis of the above scheme, optional, Figure 3 is a schematic diagram of the cross section of an optical fiber cable, such as Figure 3As shown, the optical fiber cable includes a wire core, a waterproof filler, an anti-interference inner sleeve and an outer sheath, wherein the outer layer of the anti-interference inner sleeve is wrapped with an outer sheath, the cross-section of the anti-interference inner sleeve is circular, a separation layer is provided inside the anti-interference inner sleeve, the wire core is provided in the separation layer of the anti-interference inner sleeve, and the separation layer is filled with waterproof filler.

[0069] The core of an optical fiber cable is generally made of high-purity glass or plastic with a high refractive index. The optical signal can propagate forward along the axial direction of the optical fiber through refraction in the core.

[0070] The cross-section of the anti-interference inner sleeve of the optical fiber cable is annular, and there is a separation layer in the ring. In order to ensure that the core does not shake during operation and affect the propagation of the optical signal, a waterproof filler is filled in each separation layer. The wrapping of the core with the waterproof filler can reduce the vibration of the core and increase the waterproof ability of the optical fiber cable. At the same time, the outer surface of the anti-interference inner sleeve is wrapped with an outer sheath to further increase the stability of the inside of the optical fiber cable and enhance the wear resistance and corrosion resistance of the optical fiber cable. In a feasible solution, if there are multiple cores in the optical fiber cable, partitions can be added to the separation layer to divide the space in the separation layer. The number of partitions can be determined by the number of cores, that is, each core exists in a separate separation layer, and waterproof material is filled between the core and the partition. The cores do not touch each other, thereby preventing the cores from getting entangled and the optical signal from being interfered with by other cores.

[0071] The benefit of this arrangement is that it can prevent interference between the cores by optimizing the internal structure of the optical fiber cable, which is beneficial to improving the accuracy of optical signal transmission and making the acquired water use data more accurate.

[0072] Example 3

[0073] Figure 4 This is a schematic diagram of the basic structure of the smart water meter device provided in the embodiment of the present application. Figure 4 As shown, the base watch includes a base watch lower layer, a lower box base, a lower box, a watch movement and an upper cover.

[0074] The lower layer of the base surface can be a hollow body that can be connected to a water pipe. The two ends of the lower layer of the base surface are respectively connected to the two ends of the water pipe. There is an impeller in the hollow cavity. When the water in the water pipe starts to flow, the water flow pushes the impeller to rotate in the cavity, and the number of rotations of the impeller is used to record the water flow through the cavity.

[0075] The lower box base can be used to prevent water from overflowing from the lower layer of the base surface, resulting in inaccurate water flow statistics. It can seal the lower layer of the base surface and facilitate the installation of the lower box.

[0076] The lower box can be the lower half of the meter box in the smart water meter for placing the meter core. The lower box can be fixed to the lower box base by screws or slots, so that the meter core part is connected to the lower layer of the base meter.

[0077] The meter core can be the core part of the smart water meter used to calculate water consumption, control the communication module to report water consumption data, and execute instructions from the water resources management platform. It is placed in the space formed by the connection between the lower box and the upper cover.

[0078] The upper cover, together with the lower box, forms a protective housing for the watch movement. The upper surface of the upper cover has an opening that is the same size as the display screen within the watch movement, allowing access to the display screen without removing the upper cover. It is understood that the upper cover may also be provided with a cover to conceal the opening when the display screen is not required, thereby minimizing damage to the watch movement and extending its service life.

[0079] The advantage of this arrangement is that the base meter capable of collecting water use data can be formed through the close connection between the lower layer of the base meter, the lower box and other components, making the smart water meter easy to install, firmly connected to the water pipe and not easily damaged, which is conducive to the accurate collection of water use data.

[0080] Based on the above solution, optionally, the meter core includes a counter, a control module and a display screen; wherein the counter is used to collect the water consumption flowing through the smart water meter, and the display screen is used to display the water consumption data.

[0081] The counter is connected to the impeller in the base meter's lower layer. Rotation of the impeller triggers the counter's sensor, such as a reed switch or Hall effect element, generating a pulse signal. Each time the impeller rotates one full revolution or passes a specific position, the sensor generates a pulse. The system collects, accumulates, and stores these pulse signals. The system counts the number of impeller revolutions to determine the number of revolutions. The product of these revolutions and the cavity volume in the base meter's lower layer is used as the water volume flowing through the smart water meter.

[0082] The display screen can be a control module that calculates and organizes the water consumption and water fee amount, and then controls the display screen to display the water consumption and water fee amount, so that users can read the water consumption data intuitively.

[0083] The advantage of this arrangement is that the water consumption data can be collected, calculated and sorted through the meter core, and the water flow data can be displayed, which is conducive to users to read the water consumption data intuitively and improve the user experience.

[0084] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
