[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The following describes the protection method, device and electronic device for automatically monitoring abnormal current of the smart water meter of the embodiment of the present application with reference to the accompanying drawings. In view of the abnormal current problem mentioned in the above background technology, the present application provides a protection method for automatically monitoring abnormal current of a smart water meter. In this method, the current working mode is intelligently judged, normal operation is maintained in the large current mode, and power consumption monitoring is started in the small current mode. Once an abnormal current is found, it automatically enters the protection mode and executes protection measures, which effectively reduces the power consumption abnormality risk of the smart water meter in the absence of network or low power consumption requirements, ensures the accuracy and service life of the water meter measurement, avoids economic losses and water use disputes caused by power consumption problems, and improves the reliability and user satisfaction of the smart water meter. As a result, the problem of increased or even out-of-control power consumption in the prior art when there is no network or the network signal is poor, resulting in a short service life, inaccurate measurement, and causing economic losses and water use disputes is solved.

[0026] Specifically, Figure 1 A flow chart of a protection method for automatically monitoring abnormal current for a smart water meter provided in an embodiment of the present application.

[0027] like Figure 1 As shown, the protection method of the intelligent water meter automatically monitoring abnormal current includes the following steps:

[0028] In step S101, the current working mode is acquired.

[0029] Among them, the current working mode includes a large current working mode and a small current working mode.

[0030] It can be understood that the embodiment of the present application accurately obtains the current working mode of the smart water meter, which facilitates the subsequent monitoring of abnormal current conditions.

[0031] In step S102, the current working state is determined according to the current working mode, wherein if the current working mode is a large current working mode, the control circuit continues to work, and if the current working mode is a small current working mode, the power consumption monitoring circuit is started.

[0032] Among them, the high-current working mode refers to the current consumption mode in which the smart water meter or other equipment is in normal working state, especially when transmitting a large amount of data, processing or performing high-power consumption tasks; the low-current working mode refers to the current consumption mode in which the smart water meter or other equipment is in low-power state. In this mode, the device is usually in standby, sleep or low-frequency working state.

[0033] It is understandable that the embodiment of the present application accurately controls the working state of the smart water meter by intelligently identifying the current working mode, that is, the large current working mode and the small current working mode. In the large current working mode, the control circuit continues to operate efficiently to ensure the stability and accuracy of the water meter in high-power tasks such as data transmission and instruction execution. When entering the small current working mode, the power consumption monitoring circuit is automatically started to carefully monitor the current consumption in the low power state, and potential power consumption anomalies are discovered and processed in time, effectively avoiding equipment failures and shortened life due to improper power consumption management in a low power environment. This intelligent control strategy not only improves the working efficiency and reliability of the smart water meter, but also significantly reduces energy consumption, extends the service life of the equipment, and brings users a more stable, economical and environmentally friendly water experience.

[0034] In step S103, if the power consumption monitoring circuit detects abnormal current, the smart water meter will automatically enter the protection mode and execute corresponding protection measures until the circuit returns to normal.

[0035] It is understandable that in the embodiment of the present application, when the power consumption monitoring circuit detects abnormal current, the smart water meter can respond quickly, automatically enter the protection mode, and execute a series of preset protection measures, such as reducing power consumption, cutting off non-essential circuits, etc., to ensure the safety and stability of the water meter circuit. This mechanism effectively prevents abnormal current from damaging the internal circuit of the smart water meter, avoids equipment failure and data loss caused by abnormal current, thereby ensuring the long-term stable operation of the water meter and the accuracy of measurement. In addition, the automatic recovery function ensures that after the water meter circuit returns to normal, it can quickly resume work, reducing the service interruption time caused by failures, and improving user experience and water management efficiency.

[0036] In an embodiment of the present application, if the power consumption monitoring circuit detects an abnormal current, the smart water meter will automatically enter a protection mode and execute corresponding protection measures until the circuit returns to normal, including: the power consumption monitoring circuit detects the working status of the preset unit; if the working status of the preset unit shows that the power consumption is abnormal, the corresponding exception handling mechanism is immediately started until the power consumption returns to normal and the control circuit starts working again.

[0037] Among them, the preset units are the first unit, the second unit, the third unit and the fourth unit according to the priority, among which the first unit is the NB unit, the second unit is the touch button unit, the third unit is the Bluetooth unit, and the fourth unit is the motor drive unit.

[0038] It is understandable that the embodiment of the present application monitors the working status of the preset unit in real time through the power consumption monitoring circuit. Once abnormal power consumption is found, the abnormal handling mechanism is immediately triggered, and measures such as reducing power consumption and adjusting the working mode are quickly taken until the power consumption returns to normal levels. This mechanism effectively prevents equipment damage or performance degradation caused by abnormal power consumption, and ensures that the smart water meter continues to operate in an efficient and stable state. At the same time, it improves the self-protection ability of the equipment, reduces the inconvenience and losses caused by downtime due to faults, and provides users with a more reliable and lasting water metering service.

[0039] Specifically, Figure 2 As shown, VNB supplies power to the NB unit and the driving end of the motor driver chip, and VBB supplies power to the Bluetooth unit, the motor driver chip control power supply VDD, and the touch chip VDD; when the meter is working statically, the VNB_Ctr pin is high level, and the PMOS tube T8 is disconnected. At this time, VNB is powered by VBAT through the resistor R7. When any or more of the NB unit, motor driver unit, Bluetooth unit, and touch button unit have abnormally large currents, a voltage drop occurs at the R7 connected to the VNB end, and Q1 is turned on. After being turned on, a high-level signal appears at the VNB_Det end. The single-chip computer determines the abnormal current and determines the source of the abnormal current by turning off the NB unit, touch button unit, Bluetooth unit, and motor driver unit in turn. When the above power supply units need to support work with large currents, VNB_Crt is set low, and VBAT and VNB are turned on to power the units.

[0040] The resistance value of R7 is matched according to the size of the limited monitoring current. When VNB_Crt is at a high level, the meter end is in a static working mode, and the NB unit, motor drive unit, Bluetooth unit, and touch button unit are in a dormant state. At this time, the current limit size is not more than 70uA (based on the test resistance value of R7). When the current consumption of the above power supply units exceeds 70uA in the static dormant state, Q1 is turned on, VNB_Det is at a high level, triggering the IO interrupt, and the microcontroller performs delay processing. After 10 seconds, the VNB_Det level status is read. If VNB_Det is low, it runs normally without any processing. If the VNB_Det level is at a high level, the abnormally large current flag is set and the abnormal current troubleshooting process is entered.

[0041] In an embodiment of the present application, the exception handling mechanism includes but is not limited to disconnecting or reducing the power supply to non-critical units, isolating abnormal units, recording abnormal events and setting abnormal flags, and prompting users with fault information and possible solutions through the user interface.

[0042] In an embodiment of the present application, after the smart water meter enters the protection mode, it also includes: setting a detection cycle, and detecting the current state of the circuit according to the detection cycle; if the current state is normal, gradually restoring the operation of the preset unit, otherwise the protection mode is not exited.

[0043] It is understandable that the embodiment of the present application sets a detection cycle to regularly detect the current state of the circuit to ensure the safe operation of the smart water meter. During the detection cycle, if the current state of the circuit is normal, the operation of the preset unit is gradually restored so that the smart water meter can resume normal operation. On the contrary, if the current state is still abnormal, the protection mode will not be exited, and monitoring and protection will continue to be performed to prevent damage to the equipment or expansion of the fault. This mechanism not only improves the self-protection ability of the smart water meter, but also effectively avoids equipment damage and data loss caused by abnormal current, ensuring the stability and reliability of the water meter.

[0044] According to the protection method for automatically monitoring abnormal current of a smart water meter proposed in the embodiment of the present application, the current working mode is intelligently judged, normal operation is maintained in the large current mode, and power consumption monitoring is started in the small current mode. Once abnormal current is detected, the protection mode is automatically entered and protection measures are executed, which effectively reduces the power consumption abnormality risk of the smart water meter in the absence of network or low power consumption requirements, ensures the accuracy and service life of the water meter, avoids economic losses and water use disputes caused by power consumption problems, and improves the reliability and user satisfaction of the smart water meter. Thus, the existing technology solves the problems of increased or even uncontrolled power consumption when there is no network or poor network signal, resulting in short service life, inaccurate measurement, economic losses and water use disputes.

[0045] The following will describe a specific embodiment of the protection method for automatically monitoring abnormal current in a smart water meter. Figure 3 As shown, including:

[0046] Step 1: After the abnormal high current mark appears, first disconnect the power supply of the NB unit, put the relevant pins into sleep or power-off processing, and then read the VNB_Det pin level after one minute. If the level is high, it is considered that the NB unit current is normal, and then execute step 2. If the level is low, it means that the NB unit is abnormal and causes high current, and enter the NB current abnormality processing mechanism.

[0047] NB current abnormality handling mechanism: Set the NB unit current abnormality flag, and then configure the reporting mode to power-off mode, control the module in power-off mode, and reduce the power consumption of the module. If the NB unit current abnormality flag is set and the MCU and module communication abnormality is reported three times in a row, the communication module is considered abnormal and can no longer work normally, and the NB reporting function is no longer enabled.

[0048] Step 2: After checking the NB unit, if the VNB_Det pin level is still high, put the key power supply and related pins into sleep or power-off mode, and then read the VNB_Det pin level after 2 minutes. If the level is high, the key unit current is considered normal, and then proceed to step 3. If the level is low, it means that the key unit is abnormal and the high current is caused, and the key current abnormality processing mechanism is entered.

[0049] Abnormal button current handling mechanism: Turn off the power supply to the touch buttons, turn on the LCD and keep the screen on. To prevent the need to press buttons to operate the device, reset the buttons after a full hour, turn on the button function and re-judge the abnormal current.

[0050] Step 3: After checking the button unit, if the VNB_Det pin level is still high, put the Bluetooth power supply and related pins into sleep or power-off mode, and then read the VNB_Det pin level. If the level is high, the Bluetooth unit current is considered normal, and then proceed to step 4. If the level is low, it means that the Bluetooth communication unit is abnormal and causes a large current, and the Bluetooth current abnormality handling mechanism is entered.

[0051] Bluetooth unit current abnormality handling mechanism: power off the Bluetooth unit, set the Bluetooth unit power current abnormality flag, control the Bluetooth unit to power on again and initialize the Bluetooth unit after a full hour, reconfigure Bluetooth related parameters, re-enable Bluetooth broadcasting, and restart the current detection function.

[0052] Step 4: After checking the Bluetooth unit, the VNB_Det pin level is still high, so the valve control unit power supply and related pins are put into sleep or power-off mode, and then the VNB_Det pin level is read. If it is low, the valve control unit current abnormality flag is set, and the valve control related power supply is turned off. If the level is high, it is considered that the valve control unit current is normal, and the abnormal current is caused by other devices outside the monitoring unit or misjudgment during the troubleshooting process, and the abnormal handling mechanism of other units is entered.

[0053] Other unit abnormality handling mechanisms: The power supply VNB is processed by T8 normally open to reduce the abnormal current consumption on R4 and R11, restore the low power mode of NB, restore the touch button function, restore the normal Bluetooth broadcast state, and the LCD prompts related abnormalities, clears the abnormal operation across the whole hour, and re-judges the abnormal current;

[0054] After completing the above steps, if there is an abnormal sign, the abnormal display will be performed and the corresponding fault code will be displayed on the LCD interface.

[0055] In summary, the present invention gradually checks the current status of key components such as the NB unit, button unit, Bluetooth unit and valve control unit. Once an abnormality is found, protective measures such as power off and sleep are immediately taken, and the corresponding abnormality handling mechanism is started. This process ensures that the water meter can respond quickly when facing current abnormalities, effectively isolate the fault, protect the equipment from damage, and restore other normal functions. Finally, the fault code is displayed through the LCD interface, which is convenient for users or managers to take timely measures.

[0056] Next, a protection device for automatically monitoring abnormal current in a smart water meter according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0057] Figure 4 It is a block diagram of a protection device for automatically monitoring abnormal current in a smart water meter according to an embodiment of the present application.

[0058] like Figure 4 As shown, the protection device 10 for automatically monitoring abnormal current of the smart water meter includes: an acquisition module 100, a monitoring module 200 and a protection module 300.

[0059] Among them, the acquisition module 100 acquires the current working mode, wherein the current working mode includes a large current working mode and a small current working mode; the monitoring module 200 is used to judge the current working state according to the current working mode, wherein if the current working mode is a large current working mode, the control circuit continues to work, and if the current working mode is a small current working mode, the power consumption monitoring circuit is started; the protection module 30 is used for if the power consumption monitoring circuit detects abnormal current, the smart water meter will automatically enter the protection mode, and execute corresponding protection measures until the circuit returns to normal.

[0060] It should be noted that the above explanation of the embodiment of the protection method for automatically monitoring abnormal current of the smart water meter is also applicable to the protection device for automatically monitoring abnormal current of the smart water meter of this embodiment, and will not be repeated here.

In this way, the problems in the prior art that power consumption increases or even gets out of control when there is no network or the network signal is poor, resulting in a short service life, inaccurate measurement, and causing economic losses and water use disputes are solved.
