DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, Figure 1 1 is an architecture diagram of a water level detection system 100 provided by an embodiment of the present invention, and the water level detection system includes: a water level detection device 300, a server 101, and an intelligent device 102. The water level detection device 300 also includes a first determination module, which can be used to perform voltage detection on the target electrode to determine the first target voltage when starting the water level detection; a second determination module, which can be used to perform voltage pulse detection on the current target electrode based on a preset detection pulse interval to determine the second target voltage; and a third determination module, which can be used to determine the current water level state by calculating the first target voltage and the second target voltage.

[0021] Specifically, the initial power-on can be the state when the smart device is first powered on and starts to operate. Generally speaking, in this state, the smart device can perform a series of self-tests, initializations, parameter configurations, and other behaviors. In this embodiment, the smart device can be any smart electric water heater. It can be understood that the self-tests, initializations, parameter configurations, and other behaviors can refer to the smart electric water heater adjusting its own heating parameters and configuring corresponding heating strategies according to the current state of the target electrode. For example, when the state of the target electrode is detected to be good during self-test, the heating temperature is adjusted, and the corresponding heating time and heating detection are configured.

[0022] The above-mentioned target electrode can be used to measure the current voltage. Generally speaking, the corresponding voltage data can be measured according to the electrochemical effect generated by the contact between the target electrode and the medium. More specifically, the above-mentioned target electrode can be determined according to the parameters of the above-mentioned smart device, and can include but is not limited to electrodes in the form of induction electrodes, contact electrodes, and capacitive electrodes. In this embodiment, different electrodes can be selected as the above-mentioned target electrode according to different heating environments and heating requirements. For example, the smart electric water heater in this embodiment needs to measure the voltage according to the electrochemical effect generated by the contact between the electrode and the water in the inner tank of the electric water heater, so a contact electrode can be selected.

[0023] The above-mentioned first target voltage can be obtained by detecting the voltage of the target electrode when starting water level detection. This voltage can be used as the reference voltage of the above-mentioned smart device when it is initially powered on, and is used to perform logical algorithm calculations with the second target voltage to determine the final water level state, that is, to determine the initial electrical state of the above-mentioned smart device.

[0024] The above-mentioned preset detection pulse interval can be a parameter used to define the time interval between two consecutive voltage pulse detections, such as periodically sending and detecting the voltage value of the above-mentioned target electrode. Specifically, the above-mentioned preset detection pulse interval can also be adjusted according to the water level state. For example, when there is water, since general smart devices such as smart electric water heaters cannot change from a water state to a water shortage state in a short time, but require a period of time, such as tens of seconds or even minutes, the above-mentioned preset detection pulse interval can be delayed, thereby reducing the electrode power-on time, so as to reduce the electrode from being corroded by becoming an anode due to long-term positive charge, ensure the life of the electrode and reduce the power consumption of the system. In this embodiment, an optimal detection pulse interval can be calculated according to specific application requirements (such as the heating conditions and detection conditions of the above-mentioned smart device) and environmental conditions to ensure that the system achieves the best balance between efficiency, cost and performance.

[0025] The voltage pulse detection may refer to an operation of sending a short pulse signal to the target electrode to detect a change in the electrical state of the target electrode in the medium.

[0026] The above-mentioned second target voltage may refer to the voltage value obtained by performing voltage pulse detection on the target electrode after the preset detection pulse interval. This voltage value reflects the electrical response of the electrode in the water after the first initial voltage detection, and is used to compare with the "first target voltage" to analyze and judge the change in water level. For example, the electrode voltage is detected once before outputting a detection pulse to the electrode, and this voltage is recorded as the first target voltage. Subsequently, a detection pulse is output to the electrode, and the voltage of the electrode is detected synchronously, and this voltage is recorded as the second target voltage.

[0027] The voltage logic judgment algorithm can be used to calculate and analyze the first target voltage and the second target voltage, so as to judge the current water level state in the above-mentioned smart device. The algorithm can be performed through steps such as input data, data analysis, configuration strategy and error feedback. Specifically, according to the heating conditions and parameters of the above-mentioned smart device, the voltage threshold of the water level state is set, and compared with the result obtained by calculating and analyzing the first target voltage and the second target voltage through the voltage logic judgment algorithm, the water level state is judged.

[0028] The water level status may include but is not limited to information such as the height, rate of change, and stability of the water level. In this embodiment, the water level status is judged based on whether there is water and whether heating conditions are supported when there is water.

[0029] In a possible embodiment, the water level detection system detects the voltage of the target electrode of the smart device when it is initially powered on to obtain a first target voltage, then detects the second target voltage of the target electrode at a preset detection pulse interval, and finally calculates and analyzes through a voltage logic judgment algorithm, and determines the water level status in the current smart device according to the analysis result, thereby improving the accuracy of water level detection, reducing the corrosion of the electrode caused by power-on, reducing power consumption, and enhancing the self-detection function of water level detection.

[0030] like Figure 2 As shown, Figure 2 : is a flow chart of a water level detection method provided by an embodiment of the present invention, the water level detection method comprising the steps of: 201. When starting water level detection, perform voltage detection on the target electrode to determine a first target voltage.

[0031] In an embodiment of the present invention, the above-mentioned water level detection method can be applied to the above-mentioned water level detection system, which has functions such as water level data processing, water level data transmission and reception, and water level data memory storage, and can be constructed based on a server or a server cluster. The above-mentioned server or server cluster can be an electronic device with water level data processing capabilities.

[0032] The above-mentioned starting water level detection may be the state when the above-mentioned smart device is powered on for the first time and starts to operate. Generally speaking, in this state, the above-mentioned smart device can perform a series of self-checks, initializations, parameter configurations and other behaviors. In this embodiment, the above-mentioned smart device may be any kind of smart electric water heater. It can be understood that the above-mentioned self-checks, initializations, parameter configurations and other behaviors may refer to the smart electric water heater adjusting its own heating parameters and configuring corresponding heating strategies according to the current state of the target electrode. For example, when the state of the target electrode is detected to be good during self-check, the heating temperature is adjusted, and the corresponding heating time and heating detection are configured.

[0033] The above-mentioned target electrode can be used to measure the current voltage. Generally speaking, the corresponding voltage data can be measured according to the electrochemical effect generated by the contact between the target electrode and the medium. More specifically, the above-mentioned target electrode can be determined according to the parameters of the above-mentioned smart device, and can include but is not limited to electrodes in the form of induction electrodes, contact electrodes, and capacitive electrodes. In this embodiment, different electrodes can be selected as the above-mentioned target electrode according to different heating environments and heating requirements. For example, the smart water heater in this embodiment needs to measure the voltage based on the electrical effect generated by the contact between the electrode and the water in the water heater, so a contact electrode can be selected.

[0034] The above-mentioned first target voltage can be obtained by detecting the voltage of the target electrode when starting water level detection. This voltage can be used as the reference voltage of the above-mentioned smart device when it is initially powered on, and is used to perform logical algorithm calculations with the second target voltage to determine the final water level state, that is, to determine the initial electrical state of the above-mentioned smart device.

[0035] In a possible embodiment, when the smart device is powered on for the first time, the water level detection system detects the voltage of the target electrode to obtain a corresponding first target voltage. Through this method, the water level detection system and the detected smart device can both perform self-checks to ensure the stability of the subsequent detection process.

[0036] 202. Perform voltage pulse detection on the current target electrode based on a preset detection pulse interval to determine a second target voltage.

[0037] In an embodiment of the present invention, the preset detection pulse interval can be a parameter used to define the time interval between two consecutive voltage pulse detections, such as periodically sending and detecting the voltage value of the target electrode. Specifically, the preset detection pulse interval can also be adjusted according to the water level state. For example, when there is water, since it is impossible for general equipment to change from a water state to a water shortage state in a short time, the preset detection pulse interval can be delayed, thereby reducing the electrode power-on time, so as to reduce electrode corrosion and reduce the power consumption of the system. In this embodiment, an optimal detection pulse interval can be calculated according to specific application requirements (such as the heating conditions and detection conditions of the above-mentioned smart device) and environmental conditions to ensure that the system achieves the best balance between efficiency, cost and performance.

[0038] The voltage pulse detection may refer to an operation of sending a short pulse signal to the target electrode to detect a change in the electrical state of the target electrode in the medium.

[0039] The above-mentioned second target voltage may refer to the voltage value obtained by performing voltage pulse detection on the target electrode after the preset detection pulse interval. This voltage value reflects the electrical response of the electrode in the water after the first initial voltage detection, and is used to compare with the "first target voltage" to analyze and judge the change in water level. For example, the electrode voltage is detected once before outputting a detection pulse to the electrode, and this voltage is recorded as the first target voltage. Subsequently, a detection pulse is output to the electrode, and the voltage of the electrode is detected synchronously, and this voltage is recorded as the second target voltage.

[0040] In a possible embodiment, after acquiring the first target voltage, the water level detection system transmits a pulse signal to the target electrode according to a preset detection pulse interval, and detects the second target voltage of the current target electrode.

[0041] The above method can dynamically monitor the real-time changes of the water level, improve the accuracy and response speed of water level detection, and compare the first target voltage with the continuously measured second target voltage, so that the above water level detection system can promptly detect slight changes in the water level and ensure the stable operation of water level detection.

[0042] 203. Calculate the first target voltage and the second target voltage through a voltage logic judgment algorithm to determine the current water level state.

[0043] The voltage logic judgment algorithm can be used to calculate and analyze the first target voltage and the second target voltage, so as to judge the current water level state in the above-mentioned smart device. The algorithm can be performed through steps such as input data, data analysis, configuration strategy and error feedback. Specifically, according to the heating conditions and parameters of the above-mentioned smart device, the voltage threshold of the water level state is set, and compared with the result obtained by calculating and analyzing the first target voltage and the second target voltage through the voltage logic judgment algorithm, the water level state is judged.

[0044] The water level status may include but is not limited to information such as the height, rate of change, and stability of the water level. In this embodiment, the water level status is judged based on whether there is water and whether heating conditions are supported when there is water.

[0045] In a possible embodiment, the water level detection system detects the voltage of the target electrode of the smart device when it is initially powered on to obtain a first target voltage, then detects the second target voltage of the target electrode at a preset detection pulse interval, and finally calculates and analyzes the voltage logic judgment algorithm, and determines the water level state in the current smart device according to the analysis result, thereby improving the accuracy of water level detection, reducing electrode corrosion, reducing power consumption, and enhancing the self-checking function of water level detection. In the embodiment of the present invention, when water level detection is started, voltage detection is performed on the target electrode to determine the first target voltage; based on the preset detection pulse interval, voltage pulse detection is performed on the current target electrode to determine the second target voltage; the first target voltage and the second target voltage are calculated by a voltage logic judgment algorithm to determine the current water level state. By respectively detecting the initial voltage (the voltage when the electrode has no pulse) and the voltage when the electrode has a pulse, and calculating these two voltages by a logic algorithm, and judging the result calculated by the algorithm, the state of the water level is determined, the accuracy of water level detection is improved, the corrosion of the electrode is reduced, the power consumption is reduced, and the self-checking function of the water level detection is enhanced.

[0046] Optionally, when starting water level detection, the step of performing voltage detection on the target electrode to determine the first target voltage also includes, when starting water level detection, obtaining the memory voltage of the current target electrode before power failure, the memory voltage being the voltage detected by the target electrode before the last power failure; and using the memory voltage as the first target voltage.

[0047] In an embodiment of the present invention, the above-mentioned memory voltage may refer to the last voltage value recorded by the target electrode before the device is powered off. This voltage value serves as a historical benchmark for the system and can be used to calibrate the above-mentioned water level detection system with the smart device when starting water level detection. By obtaining this memory voltage and using it as the initial value of the "first target voltage" when power is restored, it can be compared with subsequently measured voltage values ​​(such as the "second target voltage"), which helps to more accurately identify water level changes.

[0048] In a possible embodiment, by referring to the state before power failure as a reference, misjudgment caused by environmental fluctuations or changes in device state when power is restored is avoided, thereby improving the accuracy and reliability of water level detection.

[0049] Optionally, the step before performing voltage pulse detection on the current target electrode based on a preset detection pulse interval to determine the second target voltage also includes determining the conductivity of the current target electrode before performing the pulse detection; judging the health status of the electrode based on the conductivity; and determining the preset detection pulse interval based on the health status.

[0050] In the embodiment of the present invention, the above refers to the ability of a material or device to conduct current. The conductive performance is mainly determined by the conductivity or resistivity of the material. In this embodiment, the conductive performance of the target electrode can be determined to determine the current health state of the target electrode. Generally speaking, since the target electrode may produce an oxidation reaction in the environment, resulting in damage to the performance of the conductive sheet on the electrode, the health state of the electrode, that is, the conductive efficiency of the target electrode, can be judged based on the conductive performance.

[0051] More specifically, when the conductivity efficiency is higher, the voltage detection response is faster, and the water level detection process is more affected by environmental changes. Therefore, the corresponding preset detection pulse interval can be adjusted appropriately. For example, an optimal detection pulse interval can be calculated based on specific application requirements (such as the heating conditions and detection conditions of the above-mentioned smart devices) and environmental conditions to ensure that the system achieves the best balance between efficiency, cost and performance.

[0052] Optionally, in the step of performing voltage pulse detection on the current target electrode based on a preset detection pulse interval to determine the second target voltage, it also includes, after obtaining the first target voltage, synchronously performing voltage pulse detection on the target electrode at a preset detection pulse interval to obtain a corresponding predicted voltage; and comparing the predicted voltage with the voltage threshold of the target electrode to determine the second target voltage.

[0053] In an embodiment of the present invention, the above-mentioned predicted voltage may refer to the voltage detected on the current target electrode after voltage pulse detection. Since the environmental factors of the target electrode may interfere with the measured value of the voltage during pulse detection, it is also necessary to compare with the voltage threshold to determine the second target voltage to reduce errors in subsequent logical calculations.

[0054] In a possible embodiment, the water level detection system compares the predicted voltage with the voltage threshold corresponding to the target electrode. When the error is less than the error threshold, it means that the environmental factors have not affected the conductivity of the target electrode in the current state. Therefore, the comparison can be used to determine whether the predicted voltage meets the threshold standard, thereby confirming whether the state meets the conditions to serve as the new second target voltage.

[0055] This process ensures that the water level detection system can respond to small changes in water level in real time and accurately, using dynamic monitoring methods to improve water level detection accuracy and response speed.

[0056] Optionally, in the step of calculating the first target voltage and the second target voltage through a voltage logic judgment algorithm to determine the current water level state, it also includes calculating the memory voltage of the first target voltage and the second target voltage through a voltage logic judgment algorithm based on the first target voltage to determine the current working state; in the state of waiting to be confirmed that there is water, calculating the first target voltage and the second target voltage through a voltage logic judgment algorithm to determine the current water level state.

[0057] In an embodiment of the present invention, the working state may include but is not limited to a water shortage state, a short circuit state, and a water state to be confirmed. In a possible embodiment, the working state of the smart device is determined by comparing the first target voltage with a preset voltage threshold. For example, the acquired first target voltage is detected. When the first target voltage is 0, the smart device may be in a short circuit state, a water shortage state, or a water state. When the first target voltage is a negative value, it may be in a water state to be confirmed.

[0058] For example, when the voltage is zero, there are three possibilities: a. There is no water, the electrode is suspended, and the voltage is zero; b. The electrode is short-circuited (fault); c. There is water, the electrode and the electric heating tube are made of the same material, have the same natural potential, and the voltage is zero.

[0059] In a possible embodiment, when the water level detection system detects that the first target voltage is 0, it is also necessary to use a voltage logic algorithm to calculate the first target voltage according to the memory voltage of the second target voltage to determine the final working state. If the calculation result is still 0, it means that the working state is short circuit; if the calculation result is between the preset threshold range, it means that the working state is a water state to be confirmed; if the calculation result is greater than the preset threshold range, it means that the working state is lack of water.

[0060] When the first target voltage is negative, it generally means there is water. However, it is not directly judged as water at this time. It is also necessary to calculate the first target voltage and the second target voltage through the voltage logic judgment algorithm to determine the current water level state.

[0061] In another possible embodiment, the water level detection system obtains the first target voltage of the target electrode when starting water level detection, and obtains the second target voltage through pulse detection, and calculates the first target voltage and the second target voltage through a voltage logic algorithm to determine the corresponding working state.

[0062] Specifically, if it is determined that there is water in a state to be confirmed, the water level detection system performs voltage pulse detection on the target electrode according to a preset detection pulse interval, obtains the second target voltage, and uses a voltage logic judgment algorithm to calculate and analyze the first target voltage and the second target voltage to determine the current water level state.

[0063] By dynamically comparing the first target voltage and the second target voltage and combining the voltage logic judgment algorithm, the sensitivity and accuracy of water level monitoring are improved, avoiding misjudgment caused by environmental factors or deviations in electrode materials, and ensuring the stability of the water level detection system under different water quality conditions.

[0064] Optionally, in the water state to be confirmed, the first target voltage and the second target voltage are calculated by a voltage logic judgment algorithm to determine the current water level state, which also includes calculating the first target voltage and the second target voltage to obtain a voltage result; if the voltage result is within the preset interval threshold, the current water level state is judged to be the presence of water; if the voltage result is 0, the current water level state is judged to be a short circuit; if the voltage result is greater than the preset interval threshold, the current water level state is judged to be lack of water.

[0065] In an embodiment of the present invention, the above-mentioned preset interval threshold can also be set according to the electrochemical properties and circuit structure (such as the pulse output resistance size) of the above-mentioned target electrode. Generally speaking, the smaller the pulse output resistance, the larger the preset interval threshold can be set.

[0066] In a possible embodiment, after determining the water state to be confirmed and the first target voltage, the water level detection system outputs a square wave pulse with positive polarity to the electrode, and the pulse width of the square wave pulse is within 2 seconds, and synchronously detects the voltage of the electrode. The detected voltage is recorded as the second target voltage, and a subtraction operation is performed on the first target electrode and the second target electrode. When the operation result is greater than the maximum value of the preset interval threshold, the above-mentioned smart device is judged to be in a water shortage state. When the operation result is equal to 0, it is judged to be an electrode short circuit. When the operation result is within the preset interval threshold, it is judged that the current water level state of the above-mentioned smart device is water.

[0067] More specifically, the above-mentioned embodiment process as a whole is a detection cycle. In order to improve the accuracy and reliability of detection, when the water level detection is started, the chip repeats this detection process cycle 2 to 5 times, and the cycle interval is set to within 5 seconds. When the detection results are the same, the judgment result is output.

[0068] In another possible embodiment, the water level detection system can appropriately shorten or extend the detection period according to the corresponding working state of the target electrode (such as lack of water, short circuit, water), so as to reduce the power consumption of the water level detection system in the abnormal state of the above-mentioned smart device and protect the electrode.

[0070] Optionally, the above device further includes: A first acquisition module is used to acquire the memory voltage of the current target electrode before power failure when water level detection is started, wherein the memory voltage is the voltage detected by the target electrode before the last power failure; The second acquisition module is used to use the memory voltage as the first target voltage.

[0073] Optionally, the third determining module 303 includes: A second determination submodule is used to calculate the memory voltage of the first target voltage and the second target voltage based on the first target voltage through a voltage logic judgment algorithm to determine the current working state, where the working state includes a water shortage state, a short circuit state, and a water state to be confirmed; The third determination submodule is used to calculate the first target voltage and the second target voltage through a voltage logic judgment algorithm to determine the current water level state when the water is in a state to be confirmed.
