Description

Technical Field

[0001] The present invention relates to the technical field of flow measurement systems, and in particular to a low-power consumption remote intelligent networking non-magnetic intelligent flow measurement system. Background Art

[0002] New non-magnetic metering technologies, such as ultrasonic sensor metering technology, laser sensor metering technology, pressure sensor metering technology, etc. All of these new non-magnetic metering technologies can meet market demand, but for the current household market, they have high technical content and high cost. The new non-magnetic metering technology has been introduced to the market for a short time, and its stability needs to be tested by time.

[0003] Of course, non-magnetic smart metering technology has the following advantages over traditional mechanical meters: non-magnetic design avoids external interference, high-precision measurement, and can achieve accurate metering remote monitoring and water-saving control. Intelligent control can achieve remote monitoring, automatic fault alarm, automatic meter reading and other functions. With the continuous advancement of smart city construction and the increasing demand for energy conservation and emission reduction, the non-magnetic smart metering market is growing rapidly.

[0004] In recent years, a non-magnetic metering technology has emerged. On the basis of the old traditional mechanical metering, a sensing module and data processing are added to realize the electronic measurement and data collection of the flow calculation. We call it the attached non-magnetic metering technology. Compared with the traditional mechanical water meter, the attached non-magnetic metering technology has the advantages of high accuracy, good stability, and sensitive response. In addition, the attached non-magnetic metering technology is easy to install and can easily replace or upgrade the existing traditional meter, so it also has a good application prospect in the market.

[0005] The current market mainly designs additional non-magnetic metering technology based on the LC oscillation principle. When the rotating impeller rotates, when the sensing surface rotates to the metal area, the signal receiving circuit determines the position of the turntable in the metal area by detecting the signal attenuation change of the LC oscillation circuit, thereby counting the number of rotations to achieve the purpose of flow measurement. The principle of this technology is to use LC oscillation on the electromagnetic coil. When the detection inductor is in the metal area, an inductor eddy current effect will be formed, resulting in increased power consumption and faster attenuation of the sine wave signal; when the detection inductor is in the non-metallic area, there is no eddy current, and the attenuation rate of the sine wave is relatively small. This method is the same as the principle of detecting pots in induction cookers and detecting charging objects with wireless charging. Both require inductors to emit electromagnetic waves. Through the inductor eddy current effect, the power consumption increases and decreases as signal attenuation changes.

[0006] Smart networked products have very high requirements for power-saving design. The market requires a service life of more than 10 years. To achieve such a service life with the power of disposable lithium batteries, the entire system product must have low power consumption as a whole, and at the same time meet the advantages of high system stability and low safety risks, high system integration and low cost, high measurement accuracy and low power consumption.

[0007] Combining the application characteristics of non-magnetic intelligent metering technology and remote intelligent networking, the application of non-magnetic intelligent metering technology in various types of meters requires solving the power consumption problem of key technologies, and combining non-magnetic intelligent metering technology with remote intelligent networking. Efficiently coordinating low power consumption in both the measurement system and remote communication can meet the current market requirements for service life. Summary of the invention

[0008] In response to the problems in the related technology, the present application discloses a low-power remote intelligent networked non-magnetic intelligent flow measurement system, which solves the problem of high power consumption of the flow measurement system in the related technology, and achieves the advantages of high system stability and low safety risk, high system integration and low cost, high metering accuracy and low power consumption.

[0009] To achieve the above objectives, this application provides the following technical solutions:

[0010] A low-power remote intelligent networked non-magnetic intelligent flow measurement system comprises a microprocessor, wherein the microprocessor data control connection comprises a power control unit, a metering measurement signal processing module, a display drive unit and a communication transmission unit, wherein the power control unit performs intelligent power control on the system power supply, the metering measurement signal processing module can process the metering measurement signal and transmit it to the microprocessor, the display drive unit is connected to an external display to display and drive the flow information, the communication transmission unit is connected to an external communication module to communicate and set system parameters, the metering measurement signal processing module is an independently operated signal processing module, and the metering measurement signal processing module can automatically operate to sense, process and accumulate flow signals after being set by the microprocessor, and the independent operation of the metering measurement signal processing module can reduce the running time of the microprocessor, and the microprocessor, the power control unit, the display drive unit and the communication transmission unit are in sleep mode during the independent operation of the metering measurement signal processing module.

[0011] By adopting the above technical solution, the metering and measurement signal processing module can operate independently, reducing the running time of the microprocessor. The microprocessor, power control unit, display drive unit and communication transmission unit are in sleep mode, which greatly reduces the system operation power consumption.

[0012] As a further solution of the present application: the microprocessor, power control unit, metering and measurement signal processing module, display drive unit and communication transmission unit are integrated into the same chip, adopting a single-chip integrated architecture, and each function runs on the same chip.

[0013] By adopting the above technical solution and a single-chip multi-function integrated architecture, the power consumption of the system can be greatly reduced, and multiple functions can be run on the same chip. Compared with a multi-chip combination, data transmission and communication between chips can be reduced.

[0014] As a further solution of the present application: all interferences in the flow measurement system environment are corrected by the microprocessor.

[0015] By adopting the above technical solution, when the system is subject to strong external interference, the microprocessor is judged to have an event and immediately enters the standard measurement signal processing mode, where the microprocessor detects the charge value multiple times and makes an algorithm judgment, and corrects whether a misjudgment occurs under strong interference.

[0016] As a further solution of the present application: the microprocessor intervenes in the operation of the metering measurement signal processing module in an intermittent detection mode, automatically starts the microprocessor at a fixed time, and then the microprocessor monitors the detection of the metering measurement signal processing module.

[0017] By adopting the above technical solution, in the intermittent detection mode, the microprocessor sets a fixed time to wake up for intermittent detection according to the changing conditions. The longer the intermittent time, the lower the average power consumption.

[0018] As a further solution of the present application: each network node of the traffic measurement system adopts an event triggering mechanism. When an agreed event or a specific event occurs, the network node will automatically trigger a corresponding mechanism for transmitting data.

[0019] By adopting the above technical solution, the network node adopts an event trigger mechanism and communicates with the external communication module through the communication transmission unit to communicate and set system parameters, such as upload frequency, event trigger conditions, etc. When an agreed event or a specific event occurs, the network node will automatically trigger the corresponding data transmission mechanism.

[0020] When the measurement value of the accumulated flow metering storage unit exceeds a certain threshold, the accumulated flow metering storage unit will send an interrupt signal to wake up the microprocessor, and the network node can automatically send data to the cloud.

[0021] When a network node scheduled event occurs, the microprocessor will wake up automatically at the time of the scheduled event, and the network node can automatically send data to the cloud.

[0022] If an abnormal event is detected, the network node can automatically send data to the cloud for corresponding processing or notification.

[0023] As a further solution of the present application: the metering measurement signal processing module includes a mutual inductance sensing unit, a metering measurement signal processing unit and an accumulated flow metering storage unit, and the signal processing procedure of the metering measurement signal processing module is: first, the mutual inductance sensing unit senses the flow signal, and then the mutual inductance sensing unit sends the confirmed event to the metering measurement signal processing unit, and the metering measurement signal processing unit processes the flow signal. After the signal processing confirms that the sampling signal is correct, the metering measurement signal processing unit sends the flow signal to the accumulated flow metering storage unit for flow accumulation, and the accumulated flow metering storage unit stores the accumulated flow value. The signal processing procedure of the metering measurement signal processing module is performed sequentially through the mutual inductance sensing unit.

[0024] By adopting the above technical solution, the automatic polling time period of the mutual sensing unit is set through the microprocessor, so that the mutual sensing unit automatically polls each channel to detect the metal surface, reducing the time the microprocessor participates in these fixed operations, thereby reducing the running time of the microprocessor, and thus greatly reducing the system operation power consumption.

[0025] The cumulative flow metering storage unit compresses the original signal collection volume, reduces the data transmission volume, and further reduces the system power consumption.

[0026] As a further solution of the present application: when the metrology measurement signal processing module does not reverse according to the signal processing procedure, the metrology measurement signal processing unit will have an error and send an interrupt signal to the microprocessor, and the microprocessor intervenes to control and process the signal.

[0027] By adopting the above technical solution, the microprocessor wakes up and starts in the case of special events and corrects the events, which reduces the running time of the microprocessor and reduces the power consumption of the system.

[0028] As a further solution of the present application: the mutual inductance sensing unit is a capacitive mutual inductance sensing unit.

[0029] By adopting the above technical solution, the capacitive mutual inductance sensing unit is based on the capacitive mutual inductance detection principle, which is a non-contact sensing technology. The power consumption of flow measurement during long-term operation is very low, so it is very suitable for application as a remote intelligent networked non-magnetic intelligent flow measurement system.

[0030] As a further solution of the present application: the microprocessor is connected to a test and display touch button. When the test and display touch button is pressed for more than 1 second, the display will show the accumulated flow value. When the test and display touch button is pressed for more than 5 seconds, the display drive unit enters the test mode and performs functions such as debugging and calibration. When the display is not displaying, the display drive unit will be turned off.

[0031] By adopting the above technical solution, the display driving unit drives the display through the operation side, and the display is in the display mode, with a working state of 3μA, which has low power consumption.

[0032] As a further solution of the present application: the communication transmission unit is externally connected to a communication module, and the communication module includes a remote communication module, a wired communication module and a wireless communication module.

[0033] By adopting the above technical solution, the communication transmission unit communicates with the external communication module to communicate and set system parameters, such as upload frequency, event triggering conditions, etc. When an agreed event or a specific event occurs, the network node will automatically trigger the corresponding data transmission mechanism.

[0034] In summary, the beneficial effects of this application are:

[0035] By reducing the data transmission volume, data transmission frequency cycle, event trigger mechanism and sleep mode through microprocessor control, low power consumption management of the flow measurement system is achieved.

[0036] The capacitive mutual inductance sensing unit is based on the capacitive mutual inductance detection principle and is a contactless sensing technology. The power consumption of flow measurement during long-term operation is very low, which reduces the system operation power consumption.

[0037] The single-chip multi-function integrated architecture is adopted to realize multiple functions running on the same chip. Compared with the multi-chip combination method, it can reduce the data transmission and communication between chips and greatly reduce the power consumption of the system.

[0038] By compressing the original signal acquisition volume, the data transmission volume is reduced, further reducing the system power consumption.

[0039] The system controls the sleep mode of each unit under corresponding operation, and enables unused functional units to immediately enter the energy-saving state, and performs dynamic power consumption management to reduce useless power consumption.

[0040] Because the system power consumption is reduced, the service life of the system is also extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to further understand the content, features and effects of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0048] like Figure 1 As shown:

[0049] A low-power remote intelligent networking non-magnetic intelligent flow measurement system includes a microprocessor, and the microprocessor data control connection includes a power control unit, a metering measurement signal processing module, a display drive unit and a communication transmission unit.

[0050] The power control unit is connected to an external disposable lithium battery, which can intelligently control the power of the system.

[0051] The power control unit has a built-in low-power low-dropout voltage regulator and a low-voltage detector. When the disposable lithium battery in the system enters a low-power state, the low-voltage detector outputs an alarm signal, the microprocessor turns on the external communication module power, and the communication transmission unit for data transmission sends a low-power warning signal to the remote control terminal.

[0052] The display drive unit is connected to an external display to display the flow information. The microprocessor is connected with a test and display touch button. When the test and display touch button is pressed for more than 1 second, the display will display the accumulated flow value. When the test and display touch button is pressed for more than 5 seconds, the display drive unit enters the test mode to perform debugging and calibration functions. When the display does not display, the display drive unit will be turned off. The display drive unit drives the display through the operator. The display is in the display mode, which is 3μA, with low power consumption.

[0053] The communication transmission unit is connected to an external communication module for communication and setting system parameters. The communication transmission unit is connected to an external communication module, which includes a remote communication module, a wired communication module, and a wireless communication module. The communication transmission unit communicates with the external communication module to communicate and set system parameters, such as upload frequency, event triggering conditions, etc. When an agreed event or a specific event occurs, the network node will automatically trigger the corresponding data transmission mechanism.

[0054] The metering measurement signal processing module can process the metering measurement signal and transmit it to the microprocessor. The metering measurement signal processing module is an independently operated signal processing module. After being set by the microprocessor, the metering measurement signal processing module can automatically operate to sense, process and accumulate flow signals. The independent operation of the metering measurement signal processing module can reduce the running time of the microprocessor. During the independent operation of the metering measurement signal processing module, the microprocessor, power control unit, display drive unit and communication transmission unit are in sleep mode.

[0055] The metering and measurement signal processing module can run independently, reducing the microprocessor running time. The microprocessor, power control unit, display drive unit and communication transmission unit are in sleep mode, which greatly reduces the system operation power consumption.

[0056] The above-mentioned microprocessor, power control unit, metering and measurement signal processing module, display drive unit and communication transmission unit are integrated into the same chip, adopting a single-chip integrated architecture, and each function runs on the same chip.

[0057] The single-chip multi-function integrated architecture can significantly reduce the power consumption of the system and enable multiple functions to run on the same chip. Compared with the multi-chip combination, it can reduce data transmission and communication between chips.

[0058] All disturbances in the flow measurement system environment are corrected by the microprocessor, including changes in the measurement signal speed in the metering measurement signal processing unit. At this time, the microprocessor intervenes in the operation of the metering measurement signal processing module in intermittent detection mode, automatically starts the microprocessor at a fixed time, and then monitors the metering measurement signal processing module for detection. In the intermittent detection mode, the microprocessor sets a fixed time to wake up for intermittent detection according to the changing conditions. The longer the intermittent time, the lower the average power consumption.

[0059] When the system is subject to strong external interference, the microprocessor is judged to have an event and immediately enters the standard measurement signal processing mode. The microprocessor detects the charge value multiple times and makes an algorithm judgment to correct whether a misjudgment occurs under strong interference.

[0060] Each network node of the flow measurement system adopts an event trigger mechanism to communicate with the external communication module through the communication transmission unit to communicate and set system parameters, such as upload frequency, event trigger conditions, etc.

[0061] When an agreed event or a specific event occurs, the network node will automatically trigger the corresponding data transmission mechanism.

[0062] When the measurement value of the accumulated flow metering storage unit exceeds a certain threshold, the accumulated flow metering storage unit will send an interrupt signal to wake up the microprocessor, and the network node can automatically send data to the cloud.

[0063] When a network node scheduled event occurs, the microprocessor will wake up automatically at the time of the scheduled event, and the network node can automatically send data to the cloud.

[0064] If an abnormal event is detected, the network node can automatically send data to the cloud for corresponding processing or notification.

[0065] Preferably, the metering measurement signal processing module includes a mutual inductance sensing unit, a metering measurement signal processing unit and an accumulated flow metering storage unit.

[0066] The signal processing procedure of the measurement signal processing module is:

[0067] First, the mutual inductance sensing unit senses the flow signal, and then the mutual inductance sensing unit sends the confirmed event to the metering and measurement signal processing unit. The metering and measurement signal processing unit processes the flow signal. After the signal processing confirms that the sampling signal is correct, the metering and measurement signal processing unit sends the flow signal to the cumulative flow metering storage unit for flow accumulation. The cumulative flow metering storage unit stores the cumulative flow value, and the signal processing procedure of the metering and measurement signal processing module is performed in sequence through the mutual inductance sensing unit.

[0068] By setting the automatic polling time period of the mutual sensing unit through the microprocessor, the mutual sensing unit automatically polls each channel to detect the metal surface, reducing the time the microprocessor participates in these fixed operations, thereby reducing the running time of the microprocessor and significantly reducing the system operating power consumption.

[0069] The cumulative flow metering storage unit compresses the original signal collection volume, reduces the data transmission volume, and further reduces the system power consumption.

[0070] When the measurement signal processing module does not perform reverse operation according to the signal processing program, the measurement signal processing unit will generate an error and send an interrupt signal to the microprocessor, which intervenes to control and process the signal. The microprocessor determines whether a reverse event occurs.

[0071] The microprocessor wakes up and starts in the event of a special event and corrects the event, which reduces the microprocessor running time and reduces system power consumption.

[0072] Preferably, the mutual inductance sensing unit is a capacitive mutual inductance sensing unit.

[0073] The capacitive mutual inductance sensing unit is based on the capacitive mutual inductance detection principle and is a contactless sensing technology. The power consumption of flow measurement is very low during long-term operation, so it is very suitable for application as a remote intelligent networked non-magnetic intelligent flow measurement system.

[0074] The capacitive mutual inductance sensing unit points to the capacitive detection metal surface to be measured through a sampling multiplexer, and transmits the charge sampling result parameter of the measured capacitance value to the capacitive mutual inductance sensing unit, and then completes the sampling charge calculation through the capacitance value charge counting.

[0075] The metrology measurement signal processing unit processes the charge sampling parameter calculation of the capacitive mutual inductance sensing unit and confirms the result of the sampling signal through the metrology measurement signal processing unit.

[0076] The detection and measurement technology in this system adopts the capacitive mutual inductance detection non-magnetic measurement architecture, and the measurement signal processing module architecture is controlled by a microprocessor. Since the rotating impeller of the non-magnetic smart water meter is located inside the water meter, when water flows through the water meter, the water flow will drive the impeller to rotate, and drive the rotating impeller through the gear. When the flow rate of the water is different, the rotation speed and the speed of the rotating impeller will change accordingly. There is a corresponding relationship between the water flow speed and the rotation speed and the number of turns. Only by accurately mastering the rotation speed and the number of turns can the non-magnetic smart water meter measure accurately.

[0077] The metering measurement technology uses the rotating wing wheel as a metering method during the rotation process. The faster the rotating wing wheel rotates, the faster the flow rate is, and the slower the rotation speed is, the slower the flow rate is. The rotating wing wheel is covered with a conductive film of a fixed area, and the upper PCB is covered with multiple capacitive detection metal surfaces. Each capacitive detection metal surface is controlled by a multiplexer and can be used as a signal output or input. Among the multiple capacitive detection metal surfaces, there is a capacitive detection metal surface as an alternating signal output, and the other capacitive detection metal surfaces are signal inputs. When the capacitive detection metal surface is used as an alternating signal output and is connected to the waveform signal generator as a signal output point, the next adjacent capacitive detection metal surface is used as a capacitive detection input point. When the conductive film on the rotating wing wheel covers the capacitive detection metal surface as the alternating signal output and the capacitive detection metal surface as the capacitive detection input, the position of the rotating wing wheel can be known.

[0078] As the capacitive detection metal surface of the alternating signal output and the capacitive detection metal surface of the capacitive detection input, the two capacitive detection metal surfaces and the conductive film area on the rotating wing wheel can be regarded as a capacitor. The alternating signal output point flow transfers the charge to the rotating wing wheel metal film through the alternating electric field, and the capacitive detection input point detects that the induction electrode on the conductive film generates a large amount of charge. There is energy transfer (charge transfer) between the waveform signal in the same frequency range and the capacitive mutual inductance sensing unit, resulting in a large amount of charge transfer into the capacitive mutual inductance sensing unit, thereby doubling the change in the measured charge value of the capacitance value, and then determining the position of the rotating wing wheel below.

[0079] This system achieves low power consumption management of the flow measurement system by reducing the data transmission volume, data transmission frequency cycle, event trigger mechanism and sleep mode through microprocessor control.

[0080] The metering and measurement signal processing module can run independently, reducing the microprocessor running time. The microprocessor, power control unit, display drive unit and communication transmission unit are in sleep mode, which greatly reduces the system operation power consumption.

[0081] The capacitive mutual inductance sensing unit is based on the capacitive mutual inductance detection principle and is a contactless sensing technology. The power consumption of flow measurement during long-term operation is very low, which reduces the system operation power consumption.

[0082] The single-chip multi-function integrated architecture is adopted to realize multiple functions running on the same chip. Compared with the multi-chip combination method, it can reduce the data transmission and communication between chips and greatly reduce the power consumption of the system.

[0083] By compressing the original signal acquisition volume, the data transmission volume is reduced, further reducing the system power consumption.

[0084] The system controls the sleep mode of each unit under corresponding operation, and enables unused functional units to immediately enter the energy-saving state, and performs dynamic power consumption management to reduce useless power consumption.

[0085] Because the system power consumption is reduced, the service life of the system is also extended.

[0086] Finally, it should be noted that the above disclosure is only a preferred embodiment of the present application and is not intended to limit the present application.
