Description

Technical Field

[0001] This invention relates to the technical field of water meter water volume acquisition, and more specifically, to a water volume acquisition device and method based on an electric power communication channel. Background Technology

[0002] Currently, multi-meter data collection has become an essential device for next-generation smart homes and smart IoT. There are several methods to achieve multi-meter joint collection and unified data upload. However, in the use of existing solutions, apart from electricity meters which have direct circuits for power supply, other devices face power supply issues. Currently, water meters and gas meters are powered by batteries. Through on-site communication, it was found that when the water meter battery is depleted, the batteries of water meters connected to the multi-meter system are often not replaced, resulting in communication failure. After 1 to 2 years of use, communication can no longer be guaranteed.

[0003] Prior art document 1 discloses an NFC water meter and a water meter data acquisition system. The controller of the NFC water meter is connected to a communication unit. The NFC module of the communication unit is equipped with an EEPROM. When the water meter is functioning normally, the controller wirelessly transmits water meter data to the water management platform via an NB-IoT communication module. When the water meter malfunctions, the controller stores the water meter data in the EEPROM and sends the water meter data to a smart terminal via the NFC module. The smart terminal then transmits the water meter data to the water management platform. A water meter malfunction occurs when either the NB-IoT communication module fails to transmit data or the power consumption exceeds a preset value. Prior art document 1 uses the NFC module to transmit water usage data to the smart terminal, which in turn transmits the data to the water management platform. This reduces battery consumption, extends the water meter's lifespan, and allows for rapid data upload via the NFC module and smart terminal even when the water meter cannot transmit data normally, ensuring timely reporting and statistics of water usage data and facilitating normal meter reading. However, prior art document 1 has several drawbacks. It cannot overcome the barriers between different data acquisition devices, still relies on the water meter to connect to the communication unit, and still requires an additional battery to power the water meter. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water meter system for multi-meter integrated water volume collection based on high-frequency power communication acquisition equipment. This system enables water meters to record data without needing to transmit data via communication, significantly reducing the power consumption of water meters.

[0005] The present invention adopts the following technical solution.

[0008] Preferably, the water flow channel adopts a rotary multi-stream channel, where the water flow tangentially impacts the impeller from the inlet of the casing to make it rotate. The water flow from the water flow channel is divided into multiple streams by the distribution function of the impeller box, and the multiple streams impact the impeller tangentially from the inlet of the impeller box.

[0009] Preferably, the mechanical energy storage device further includes a reduction gear and a planar spiral spring, and the generator is connected to the mechanical energy storage device to realize mechanical energy storage.

[0010] Preferably, when water flows through the water channel, the water flows through the mechanical energy storage device to store energy, and at the same time the water flows to drive the generator to work; when no water flows through the water channel, the mechanical energy storage device drives the generator to work.

[0011] Preferably, when water flows through the water channel, the water flow first drives the main shaft of the mechanical energy storage device to rotate. The main shaft is the main drive shaft connected to the impeller of the water channel. The water flow drives the motor to generate electricity. At the same time, the reduction gear on the main shaft drives the planar spiral spring to move, driving the mechanical energy storage device connected to the main shaft to charge. Meanwhile, the main shaft stabilizes the water flow through the reduction gear, and the micro generator connected to the main shaft rotates in the forward direction to generate electricity. When the water flow stops, the planar spiral spring of the mechanical energy storage device releases energy, driving the micro generator to rotate in the reverse direction to generate electricity.

[0012] Preferably, the capacitor storage circuit is connected to the power metering chip, which records the positive power generation of the generator, i.e., voltage data V1, and the capacitor storage circuit provides the power metering chip with the electrical energy required for its operation.

[0013] Preferably, each user is provided with an electricity meter, and the electricity meter reading module is installed on the electricity meter. After the electricity meter reading module reads the voltage data V1 at a preset frequency, the electricity meter uses the power communication channel to send the voltage data V1 to the data acquisition terminal by adding a data identifier to the existing power communication protocol. The data acquisition terminal then sends the data to the data acquisition master station.

[0014] Preferably, the user's water consumption L and voltage data V1 satisfy the following relationship: water consumption L = a * V1, where coefficient a is a conversion factor.

[0015] The present invention also provides a water volume acquisition method based on a power communication channel, comprising the following steps:

[0016] Step 1: When there is water flow in the water pipe, the water flow impacts the mechanical energy storage device and the generator, causing the mechanical energy storage device to store energy and the generator to work; when there is no water flow in the water pipe, the mechanical energy storage device releases energy to drive the generator to work.

[0017] Step 2: The generator charges the capacitor storage circuit, which in turn powers the power metering chip and the near-field storage module.

[0018] Step 3: The power metering chip integrates and records the power consumption, and then stores it in the near-field storage module;

[0019] Step 4: The electricity metering module reads the electricity data from the memory according to the preset frequency and reports it to the data acquisition terminal through the electricity meter. The data acquisition terminal reports the electricity data to the main data acquisition station, and the main data acquisition station converts the electricity data to obtain the water volume data.

[0023] The beneficial effects of this invention are as follows: Compared with the prior art, this invention utilizes water flow impact power generation, eliminating the need for an additional power supply in the water volume acquisition device. Water meter data is read via near-field reading of the electricity meter, and the data is uploaded through the electricity meter's power acquisition system, achieving a unified water volume data reading and recording function for multiple meters. This invention records water flow by generating electricity from water flow and uses the electricity generated by the flowing water to store the power data in a wireless radio frequency storage module.

Utilizing water flow impact power generation eliminates the need for battery equipment, avoids the frequent opening of water pipes, and prevents unstable motor power generation caused by prolonged battery disuse; it achieves water volume measurement and data uploading without a power source through the power acquisition channel. Attached Figure Description

[0024] Figure 1 This is a schematic diagram of the structural relationship of the water volume acquisition device based on the power communication channel in this invention;

[0025] Figure 2 This is a flowchart illustrating the water volume acquisition method based on the power communication channel in this invention. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. The embodiments described in this application are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this invention.

[0027] like Figure 1 As shown, the present invention provides a water volume acquisition device based on a power communication channel. The system includes: a water flow channel, a mechanical energy storage device, a generator, a capacitor storage circuit, a power metering chip, a near-field storage module, a power reading module, a power meter, an acquisition terminal, and an acquisition master station.

[0028] The water flow channel is connected to the mechanical energy storage device. When water flows in the water flow channel, the mechanical energy storage device stores mechanical energy.

[0029] The mechanical energy storage device is connected to the generator, and the generator is driven by water flow or the mechanical energy storage device.

[0030] The generator is connected to the power metering chip. When there is water flowing in the water channel, the generator generates electricity in the forward direction. When the water flow stops, the generator generates electricity in the reverse direction.

[0031] The positive power generation of the generator is recorded by the power metering chip, and the positive power generation is used to calculate the water flow.

[0032] The generator is connected to a capacitor storage circuit, which stores the reverse power generated by the generator and supplies power to the power metering chip.

[0033] The near-field storage module can be installed on the water pipe. The power metering chip is connected to the near-field storage module. The power generation recorded by the power metering chip is written into the near-field storage module for storage.

[0034] Each user has its own corresponding electricity reading module and electricity meter, which makes it easy to save the water and electricity data of different users. The electricity reading module is installed on the electricity meter and is used to read the positive power generation recorded by the electricity metering chip and send it to the main station for electricity data acquisition through the electricity acquisition system.

[0035] The data acquisition terminal receives the electricity data read by the electricity meter reading module and forwards and uploads the electricity data to the main data acquisition station of the distribution area used by the electricity meter.

[0036] The main data collection station calculates the water consumption information of users based on electricity data.

[0037] Specifically, the water flow channel in this invention adopts a rotary multi-jet channel, which is equipped with an impeller box. The water flow tangentially impacts the impeller from the inlet, causing it to rotate. Through the distribution function of the impeller box, multiple water jets are tangentially impacted on the impeller from the inlet of the impeller box, so that the axial impact force of the water flow on the impeller is balanced, reducing the wear of the impeller support part, and structurally reducing the impact of the overall water flow channel installation and scaling on measurement errors.

[0038] Furthermore, the mechanical energy storage device also includes a reduction gear and a flat spiral spring. The generator is connected to the mechanical energy storage device, specifically, the generator's turbine is connected to the flat spiral spring via the reduction gear. The mechanical energy storage device can store mechanical energy and balance the instability in electrical power caused by the impact of water flow velocity.

[0039] The generator is connected to a mechanical energy storage device. When there is water flow in the water channel, the water flows through the mechanical energy storage device to store energy, and at the same time, the water flow drives the generator to work. When there is no water flow in the water channel, the mechanical energy storage device drives the generator to work.

[0040] Preferably, the generator used in this invention is a bidirectional micro-generator, and the planar spiral spring of the mechanical energy storage device is connected to the micro-generator through a one-way gear, thereby realizing the connection between the mechanical energy storage device and the generator.

[0041] Specifically, when water flows through the water channel, the water flow first drives the main shaft of the mechanical energy storage device to rotate. The main shaft is the main drive shaft connected to the impeller of the water channel. On the one hand, the water flow drives the motor to generate electricity. The electricity generated by the generator can be used to calculate the water volume through the integrator chip. On the other hand, it is used to replenish the electricity of the storage capacitor. At the same time, it also drives the reduction gear on the main shaft to move the planar spiral spring, which drives the mechanical energy storage device connected to the main shaft to charge. Meanwhile, the main shaft stabilizes the water flow through the reduction gear, and the micro generator connected to the main shaft rotates in the forward direction to generate electricity. When the water flow stops, the planar spiral spring of the mechanical energy storage device releases energy and drives the micro generator to rotate in the reverse direction to generate electricity.

[0042] The amount of electricity generated by the generator is related to the water flow speed and the reduction gear. It can be calculated based on the configuration of the reduction gear. The amount of electricity generated is positively correlated with the water flow rate in the water meter.

[0043] Furthermore, the generator is connected to the capacitor storage circuit. The electricity generated by the generator is used to charge the capacitor storage circuit, which in turn provides power metering and storage for the normal operation of the power metering chip.

[0044] The capacitor storage circuit is connected to the power metering chip. Since the power recording chip records voltage fluctuation data more reliably than other methods, the power metering chip integrates and records the generator's power-on time and voltage fluctuations. The power metering chip records the generator's positive power generation, that is, the power generation data generated by the water flow. The positive power generation of the generator is represented by the voltage data V1, and the capacitor storage circuit provides the power metering chip with the electrical energy required for its operation.

[0045] Each user is assigned an electricity meter. In this invention, a smart IoT electricity meter is used. The electricity meter reading module is installed on the electricity meter. After the electricity meter reading module reads the voltage data V1 at a preset frequency, the electricity meter uses the power communication channel to send the voltage data V1 to the data acquisition terminal by adding a data identifier to the existing power communication protocol. The data acquisition terminal then sends the data to the data acquisition master station.

[0046] The change in voltage value should be positively correlated with the water flow rate in the water meter. In this invention, the user's water consumption L and voltage data V1 satisfy L=a*V1, where the coefficient a is a conversion factor. The value of a varies for different devices, so it can be determined by those skilled in the art in advance as a fixed value based on the device conditions.

[0047] The near-field storage module can transmit data over a short distance, requiring the reading module on the electricity meter to assist in reading and forwarding the data. In this invention, the near-field storage module uses an RFID chip. After the electricity metering chip writes the power generation data into the near-field storage module for storage, it can be directly read by the electricity reading module through the near-field storage module.

[0048] The electricity meter can adopt the new IoT meter module format and forward the uploaded electricity data to the distribution area data acquisition terminal used by the electricity meter.

[0049] Since the electricity meter can also record the user's electricity consumption, the electricity meter in this invention will set different data identifiers when recording different electricity data, so that the acquisition master station can distinguish the voltage data V1 generated by water flow. The acquisition master station determines the voltage data V1 generated by water flow based on the data identifier recorded by the electricity meter, and restores the voltage fluctuation data to water volume change data based on the equipment file information. Since the water volume is proportional to the recorded electricity, the water volume can be calculated in the system as L = a * V1.

[0050] Furthermore, the communication section adopts the near-field communication principle. The water meter is close to the electricity meter communication module as the main device and communication initiator. Since the electricity meter voltage and power supply can be guaranteed, the electricity meter establishes the RF field for reading, and the water meter responds. Only an RF antenna needs to be set in the water meter to passively respond to the magnetic field emitted by the electricity meter.

[0051] like Figure 2 As shown, this invention also proposes a water volume acquisition method based on a power communication channel. The aforementioned water volume acquisition device based on the power communication channel uses this method to acquire water volume from users. The method specifically includes the following steps:

[0052] Step 1: When there is water flow, the water flow impacts the mechanical energy storage device and the generator, causing the mechanical energy storage device to store energy and the generator to work; when there is no water flow, the mechanical energy storage device releases energy to drive the generator.

[0053] The capacitor stores mechanical energy by using water flow to impact a vortex spring. Once the mechanical energy is fully stored, the spring slowly releases the mechanical energy, driving a coaxial micro motor to generate electrical energy, which is then fed into the capacitor. The capacitor then slowly discharges the electrical energy, ensuring that the chip and storage remain in normal operation.

[0054] Step 2: The generator charges the capacitor storage circuit, which in turn powers the power metering chip and the near-field storage module.

[0055] Step 3: The power metering chip integrates and records the power consumption, and then stores it in the near-field storage module;

[0056] In terms of water flow data recording, when water flows, the generator coaxial with the impeller generates voltage fluctuations. The water flow duration and the voltage fluctuations are integrated by the power metering chip, and this power is directly recorded into the EEPROM.

[0057] Step 4: The electricity metering module reads the electricity data from the memory according to the preset frequency and reports it to the data acquisition terminal through the electricity meter. The data acquisition terminal reports the electricity data to the main data acquisition station, and the main data acquisition station converts the electricity data to obtain the water volume data.

[0058] The water volume acquisition device, which integrates the electricity meter and the data connection, is numbered the same as the electricity meter's record number but with an additional "1" added as a suffix. It records the electricity data uploaded by the water meter, meaning that the electricity data can be used to transmit water and electricity data without changing the communication protocol. After being uploaded, the acquisition master station calculates the water meter data to obtain the water volume data. Here, the water volume L = voltage data V1 * conversion factor a, where the voltage data V1 represents the forward power generation of the generator, that is, the power generation data generated by the water flow driving the generator to rotate forward.

[0059] This invention abandons the active external communication function of the water meter, and only retains the data reading and writing function of the near-field communication module (similar to RFID). For data reading, it utilizes the method of configuring a reading unit on the electricity meter to read the water meter data through the near-field reading method of the electricity meter, and transmits the data through the electricity meter power acquisition system.

[0060] The beneficial effects of this invention are that, compared with the prior art, this invention eliminates the need for battery equipment by using water flow impact to generate electricity, thus avoiding the problem of unstable motor power generation caused by long-term battery disuse; and it realizes water volume measurement and data uploading without power supply through the power acquisition channel.
