[0031] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0032] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0033] Please refer to Figure 1 , Figure 1 It is a schematic flow chart of the first embodiment of the electrode-based liquid monitoring method of the present invention.

[0034] The embodiments of the present invention provide embodiments of the electrode-based liquid monitoring method. It should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown here.

[0035] It should be noted that the execution subject of each embodiment of the electrode-based liquid monitoring method of the present invention can be a liquid monitoring device, which includes multiple electrodes, and the number of the multiple electrodes is greater than two. In addition, the liquid monitoring device can be conventionally controlled by an automatic control program. The types, styles and specific implementation details of the liquid monitoring device are not limited in each embodiment.

[0036] In this embodiment, the electrode-based liquid monitoring method includes the following steps S10-S40:

[0037] Step S10, detecting whether there is current feedback based on the current detected by the plurality of electrodes, and detecting whether there is preset pressure feedback;

[0038] The liquid monitoring device detects whether the multiple electrodes detect liquid and thus there is current feedback through a built-in processor respectively connected to the multiple electrodes, and detects whether there is a preset pressure feedback through the processor.

[0039] It should be noted that, in this embodiment, the preset pressure feedback is a pressure sensor preset in the liquid monitoring device and connected to the processor, which outputs pressure feedback to the processor when it detects that its surface is covered with liquid (including conductive liquid and non-conductive liquid) or other solid foreign matter.

[0040] Furthermore, in a feasible implementation, the liquid monitoring device further includes a pressure sensor, and the pressure sensor is also connected to the processor of the liquid monitoring device. The step of "and detecting whether there is a preset pressure feedback" in the above step S10 may include:

[0041] Step S101 , when the plurality of electrodes are synchronously or asynchronously turned on to detect whether the current feedback exists, the pressure sensor is turned on to detect whether the preset pressure feedback exists.

[0042] The liquid monitoring device can control the processor to simultaneously turn on multiple electrodes and pressure sensors to perform detection separately, thereby detecting whether there is current feedback returned by the multiple electrodes and whether there is preset pressure feedback returned by the pressure sensor. Alternatively, the liquid monitoring device can also control the processor to first turn on multiple electrodes (or pressure sensors) for detection to detect whether there is current feedback (or preset pressure feedback), and then control the pressure sensor (or multiple electrodes) to turn on for detection to detect whether there is preset pressure feedback (or current feedback).

[0043] It should be noted that, in this embodiment, the pressure sensor pre-installed in the liquid monitoring device can be any type of pressure sensor currently available on the market. The pressure sensor can detect the pressure of the liquid or other foreign matter covering it based on its own working principle, and send pressure feedback to the connected processor when it detects that it is covered with liquid or other foreign matter. It should be understood that based on the different design requirements of actual applications, in different feasible implementations, the pressure sensors that can be pre-installed in the liquid monitoring device and connected to the processor can of course be of different types and even quantities. The electrode-based liquid monitoring method of the present invention does not limit the specific type of the pressure sensor and the details of the detection working principle.

[0044] Specifically, for example, please refer to Figure 2 In the application process shown, when the liquid monitoring device reaches the predetermined detection time, the processor first controls the pressure sensor to start detection, so as to determine whether the pressure sensor detects liquid or foreign matter and has pressure feedback. If it is determined that the pressure sensor has no pressure feedback, the processor immediately controls the pressure sensor to enter a dormant state, waiting to restart for detection when the predetermined detection time is reached next time. Alternatively, if it is determined that the pressure sensor has pressure feedback, the processor immediately further controls the opening of multiple electrodes for liquid detection, and determines whether there is current feedback returned by the multiple electrodes when the conductive liquid is detected, and then controls the multiple electrodes and the pressure sensor to enter a dormant state again when it is determined that there is no current feedback.

[0045] In this embodiment, during the process of liquid monitoring by using multiple electrodes (greater than two), the liquid monitoring device further utilizes a newly added pressure sensor to assist the multiple electrodes in monitoring. Thus, compared with the traditional dual-electrode measurement method, the liquid monitoring method of the present invention is more accurate, sensitive, and has a higher monitoring efficiency.

[0046] Step S20, if the current feedback is detected, it is determined that the conductive liquid is monitored and the liquid level detection is started;

[0047] When the liquid monitoring device detects that the multiple electrodes connected to the processor detect liquid and thus there is current feedback, it directly determines that the conductive liquid has been currently monitored and synchronously turns on the preset liquid level sensor to perform liquid level detection on the conductive liquid.

[0048] It should be noted that, in this embodiment, the liquid level sensor pre-installed in the liquid monitoring device can be any type of liquid level sensor currently available on the market. The liquid level sensor can detect the liquid level data (such as liquid level height, etc.) of the liquid covering it based on its own working principle, and report the liquid level data to the connected processor when the liquid level data is detected, or output a corresponding prompt to the processor according to a predetermined scheme when the liquid level data is not detected. It should be understood that based on different design requirements of actual applications, in different feasible implementations, the liquid level sensors that can be pre-installed in the liquid monitoring device and connected to the processor can of course be of different types and even quantities. The electrode-based liquid monitoring method of the present invention does not limit the specific type of the liquid level sensor and the details of the detection working principle.

[0049] In addition, it should be understood that, based on different design requirements of actual applications, in different feasible implementations, in addition to pre-setting pressure sensors and liquid level sensors, the liquid monitoring device can of course also pre-set different sensors based on other detection needs. The electrode-based liquid monitoring method of the present invention does not specifically limit the types and quantities of sensors that can be pre-set in the liquid monitoring device.

[0050] Step S30, if it is detected that only the preset pressure feedback exists, it is determined that a non-conductive liquid or a foreign object is detected and liquid level detection is started;

[0051] When the liquid monitoring device detects that the pressure sensor connected to the processor detects liquid or foreign matter and thus there is pressure feedback, but does not detect that multiple electrodes detect conductive liquid and thus there is current feedback, it determines that non-conductive liquid or other foreign matter that has a pressure effect on the pressure sensor is currently monitored. Then, the liquid monitoring device further activates the preset liquid level sensor through the processor to perform liquid level detection on the possible non-conductive liquid.

[0052] Further, in a feasible implementation manner, in the above step S20 or step S30, the step of "starting liquid level detection" may include:

[0053] Step A: starting the liquid level sensor to detect the liquid level of the conductive liquid or the non-conductive liquid.

[0054] When the liquid level monitoring device detects that the multiple electrodes connected to the processor detect liquid and thus there is current feedback, and determines that the conductive liquid has been currently detected, the processor controls the start of the preset liquid level sensor to perform liquid level detection for the conductive liquid. Or,

[0055] When the liquid monitoring device detects that the pressure sensor connected to the processor detects liquid or foreign matter and thus there is pressure feedback, but does not detect that multiple electrodes detect conductive liquid and thus there is current feedback, it determines that non-conductive liquid or other foreign matter that has a pressure effect on the pressure sensor is currently monitored, and further activates the preset liquid level sensor through the processor to perform liquid level detection for the possible non-conductive liquid.

[0056] Specifically, for example, please refer to Figure 2 In the application process shown, when the liquid monitoring device determines that there is pressure feedback from the preset pressure sensor, the processor further controls the opening of multiple electrodes to detect the liquid, and when it determines that there is current feedback returned by the multiple electrodes when detecting the conductive liquid, it further controls the opening of the preset liquid level sensor to measure the conductive liquid detected by the multiple electrodes, so that the liquid level sensor returns the measured liquid level data such as the liquid level height of the conductive liquid to the processor (the microcontroller shown in the figure), and the processor organizes the liquid level data and outputs the predetermined result to the business system or device connected to the liquid monitoring device.

[0057] Further, in a feasible implementation manner, in the above step S30, after the step of "determining that a non-conductive liquid or foreign matter is detected and starting liquid level detection", the electrode-based liquid monitoring method of the present invention may further include:

[0058] Step S50, if the liquid level sensor detects liquid level data, it is determined that the non-conductive liquid is monitored and the liquid level data is reported;

[0059] When the liquid monitoring device detects that the pressure sensor connected to the processor detects liquid or foreign matter and thus has pressure feedback, but does not detect that multiple electrodes detect conductive liquid and thus has current feedback, it determines that non-conductive liquid or other foreign matter that has pressure effect on the pressure sensor is currently monitored, and then the processor further turns on the preset liquid level sensor to perform liquid level detection on the possible non-conductive liquid. If the liquid level sensor detects and feeds back the liquid level data to the processor, the liquid monitoring device first determines that non-conductive liquid has been monitored and reports the liquid level data returned by the liquid level sensor.

[0060] It should be noted that, in this embodiment, the liquid level monitoring device can also be pre-connected with other business systems or devices to immediately report the monitored liquid level data to other business systems or devices for corresponding business processing. Specifically, for example, the liquid level monitoring device can be pre-connected with a system for monitoring and managing the road network, so that after the liquid level monitoring device detects the liquid level data, it immediately reports the liquid level data to the system, and the system manages and controls the road network based on the liquid level data.

[0061] Further, in another feasible implementation, in the above step S30, after the step of "determining that a non-conductive liquid or foreign matter is detected and starting liquid level detection", the electrode-based liquid monitoring method of the present invention may further include:

[0062] Step S60: If the liquid level sensor detects the liquid level data, it is determined that the foreign matter is detected and a preset prompt message is reported.

[0063] It should be noted that, in the present embodiment, the preset prompt information can be a prompt to the relevant business system or staff that the sensor of the current liquid level monitoring device is covered by foreign matter, which may affect the detection accuracy and thus requires timely maintenance. It should be understood that based on the different design needs of actual applications, in different feasible implementation methods, the preset prompt information can of course adopt different information content. The electrode-based liquid monitoring method of the present invention is not limited to the specific content of the preset prompt information.

[0064] When the liquid monitoring device detects that the pressure sensor connected to the processor detects liquid or foreign matter and thus there is pressure feedback, but does not detect that multiple electrodes detect conductive liquid and thus there is current feedback, it determines that non-conductive liquid or other foreign matter that has a pressure effect on the pressure sensor is currently monitored, and then the processor further turns on the preset liquid level sensor to perform liquid level detection on the possible non-conductive liquid. If the liquid level sensor does not detect liquid level data, the liquid monitoring device determines that non-conductive liquid is not currently monitored, but that foreign matter that has a pressure effect exists on the pressure sensor. Then, the liquid level monitoring device reports to other pre-connected business systems, devices or staff that the sensor is covered by foreign matter, which may affect the detection accuracy, and thus requires timely maintenance.

[0065] In this embodiment, when the liquid monitoring device determines through monitoring that the preset pressure sensor is covered with foreign matter having a pressure effect, it immediately outputs a prompt message to the pre-connected business system or staff that the sensor of the current liquid level monitoring device is covered by foreign matter, which may affect the detection accuracy and thus requires timely maintenance. In this way, when the device sensor is affected by contaminants and the detection sensitivity is reduced, timely reporting and notification for maintenance can be made so that the preset sensor can always perform high-sensitivity detection, thereby further ensuring the accuracy and reliability of liquid detection.

[0066] Step S40: If the current feedback and the preset pressure feedback are not detected, it is determined that no liquid is detected.

[0067] When the liquid monitoring device detects that the pressure sensor connected to the processor does not detect liquid or foreign matter and thus there is no pressure feedback, and detects that multiple electrodes do not detect conductive liquid and thus there is no current feedback, it immediately determines that no liquid or other foreign matter that has a pressure effect on the pressure sensor is currently being monitored.

[0068] In this embodiment, the liquid monitoring device detects whether the multiple electrodes detect liquid and thus have current feedback through a built-in processor respectively connected to the multiple electrodes, and detects whether there is a preset pressure feedback through the processor; when the liquid monitoring device detects that the multiple electrodes connected to the processor detect liquid and thus have current feedback, it directly determines that the conductive liquid has been currently monitored and synchronously turns on the preset liquid level sensor to perform liquid level detection on the conductive liquid; or, when the liquid monitoring device detects that the pressure sensor connected to the processor detects liquid or foreign matter and thus has pressure feedback, but does not detect that the multiple electrodes detect the conductive liquid and thus have current feedback, it determines that the non-conductive liquid or other foreign matter with pressure effect on the pressure sensor is currently monitored, and then the liquid monitoring device further turns on the preset liquid level sensor through the processor to perform liquid level detection on the possible non-conductive liquid; or, when the liquid monitoring device detects that the pressure sensor connected to the processor does not detect liquid or foreign matter and thus has no pressure feedback, and detects that the multiple electrodes do not detect the conductive liquid and thus have no current feedback, it immediately determines that no liquid or other foreign matter with pressure effect on the pressure sensor is currently monitored.

[0069] Compared with the existing method of using two electrodes for liquid detection, the present invention detects the pressure generated by the liquid and the current detected by multiple electrodes, and then combines the pressure and current to monitor the liquid. In this way, it can monitor non-conductive liquids with the assistance of pressure feedback, which greatly improves the stability of liquid monitoring. In addition, by setting a plurality of electrodes greater than two to detect the current, the problem of difficulty in liquid detection due to corrosion of one of the electrodes in the two-electrode detection process is avoided, thereby effectively ensuring the accuracy and reliability of liquid detection.

[0070] In addition, an embodiment of the present invention further provides a liquid monitoring device.

[0071] Please refer to Figure 3 As shown in the structure, in this embodiment, the liquid monitoring device includes a processor, a plurality of electrodes, a pressure sensor and a liquid level sensor, wherein the number of the plurality of electrodes is greater than two, and the processor is respectively connected to the plurality of electrodes, the pressure sensor and the liquid level sensor.

[0072] Further, in a feasible implementation manner, please refer to Figure 4 and Figure 5 The liquid monitoring device also includes a base structure, and a plurality of through holes are opened on the upper surface of the base structure in a centrally symmetrical manner, and the number of the plurality of through holes is the same as the number of the plurality of electrodes.

[0073] The liquid monitoring device may specifically include four electrodes, and the base structure of the liquid monitoring device is circular. Four through holes with diameters larger than the diameters of the cylindrical electrodes and centrally symmetrical are pre-opened on the upper surface of the base structure for fixing and installing the four electrodes.

[0074] Furthermore, in a feasible implementation manner, the plurality of electrodes are respectively embedded in the plurality of through holes, and top ends of the plurality of electrodes are higher than an upper surface of the base structure.

[0075] Assume that the four electrodes of the liquid monitoring device are cylindrical electrodes with a diameter of less than 3 mm, and the diameter of the four centrally symmetrical through holes on the upper surface of the circular base structure of the liquid monitoring device is exactly 3 mm, so that the four cylindrical electrodes with a diameter of less than 3 mm are respectively embedded and fixed in the four through holes, so that each electrode is closely connected to the base structure. In addition, the front ends of the four electrodes are pre-ground into an arc and exposed 1 mm from the upper surface of the base structure, and the rear ends of the four electrodes are connected to the wires with silver paste, and the electrodes 1 and 3 of the four electrodes are set as one group, and the electrodes 2 and 4 are set as another group, and the four electrodes are respectively connected to the pins of the processor-microcontroller that process the two groups of electrodes.

[0076] Furthermore, in a feasible implementation manner, the pressure sensor is disposed on the upper surface of the base structure and is located between any two electrodes of the plurality of electrodes, and the processor and the liquid level sensor are disposed inside the base structure.

[0077] A groove is formed on the upper surface of the circular base structure of the liquid monitoring device in the area between any two adjacent through holes, so that the pressure sensor is arranged in the groove, and the processor of the liquid monitoring device - the single-chip microcomputer and the liquid level sensor are placed in the internal cavity of the circular base structure (the area circled by the dotted line in the figure).

[0078] Furthermore, in a feasible implementation manner, the material of the plurality of electrodes is a corrosion-resistant metal material, and the material of the base structure is a non-conductive material.

[0079] The four electrodes of the liquid monitoring device may be made of corrosion-resistant stainless steel, while the base structure of the liquid monitoring device may be made of non-conductive metal, plastic or other materials whose strength meets the design standards.

[0080] In this embodiment, by adding a pressure sensor to the liquid monitoring device to assist a larger number of electrodes in liquid detection, and using a new type of corrosion-resistant and oxidation-resistant material as the material of the electrode, the stability of liquid monitoring is improved, and the accuracy and reliability of liquid detection are effectively guaranteed.

[0081] In addition, in this embodiment, the processor of the liquid monitoring device of the present invention is used to detect whether there is a current feedback based on the current detected by the plurality of electrodes, and to detect whether there is a preset pressure feedback based on the pressure sensor;

[0082] The liquid monitoring device can control the processor to simultaneously turn on multiple electrodes and pressure sensors to perform detection separately, thereby detecting whether there is current feedback returned by the multiple electrodes and whether there is preset pressure feedback returned by the pressure sensor. Alternatively, the liquid monitoring device can also control the processor to first turn on multiple electrodes (or pressure sensors) for detection to detect whether there is current feedback (or preset pressure feedback), and then control the pressure sensor (or multiple electrodes) to turn on for detection to detect whether there is preset pressure feedback (or current feedback).

[0083] It should be noted that, in this embodiment, the pressure sensor pre-installed in the liquid monitoring device can be any type of pressure sensor currently available on the market. The pressure sensor can detect the pressure of the liquid or other foreign matter covering it based on its own working principle, and send pressure feedback to the connected processor when it detects that it is covered with liquid or other foreign matter. It should be understood that based on the different design requirements of actual applications, in different feasible implementations, the pressure sensors that can be pre-installed in the liquid monitoring device and connected to the processor can of course be of different types and even quantities. The electrode-based liquid monitoring method of the present invention does not limit the specific type of the pressure sensor and the details of the detection working principle.

[0084] Specifically, for example, please refer to Figure 2 In the application process shown, when the liquid monitoring device reaches the predetermined detection time, the processor first controls the pressure sensor to start detection, so as to determine whether the pressure sensor detects liquid or foreign matter and has pressure feedback. If it is determined that the pressure sensor has no pressure feedback, the processor immediately controls the pressure sensor to enter a dormant state, waiting to restart for detection when the predetermined detection time is reached next time. Alternatively, if it is determined that the pressure sensor has pressure feedback, the processor immediately further controls the opening of multiple electrodes for liquid detection, and determines whether there is current feedback returned by the multiple electrodes when the conductive liquid is detected, and then controls the multiple electrodes and the pressure sensor to enter a dormant state again when it is determined that there is no current feedback.

[0085] In this embodiment, during the process of liquid monitoring by using multiple electrodes (greater than two), the liquid monitoring device further utilizes a newly added pressure sensor to assist the multiple electrodes in monitoring. Thus, compared with the traditional dual-electrode measurement method, the liquid monitoring method of the present invention is more accurate, sensitive, and has a higher monitoring efficiency.

[0086] Furthermore, the processor of the liquid monitoring device of the present invention is also used to determine that a conductive liquid is monitored and turn on the liquid level sensor for liquid level detection if the presence of the current feedback is detected, or to determine that a non-conductive liquid or foreign matter is monitored and turn on the liquid level sensor for liquid level detection if only the preset pressure feedback is detected, or to determine that no liquid is monitored if neither the current feedback nor the preset pressure feedback is detected.

[0087] When the liquid monitoring device detects that the multiple electrodes connected to the processor detect liquid and thus there is current feedback, it directly determines that the conductive liquid has been currently monitored and synchronously turns on the preset liquid level sensor to perform liquid level detection on the conductive liquid.

[0088] It should be noted that, in the present embodiment, the liquid level sensor pre-installed in the liquid monitoring device can be any type of liquid level sensor currently available on the market. The liquid level sensor can detect the liquid level data (such as liquid level height, etc.) of the liquid covering it based on its own working principle, and report the liquid level data to the connected processor when the liquid level data is detected, or output corresponding prompts to the processor according to a predetermined plan when no liquid level data is detected.

[0089] Alternatively, when the liquid monitoring device detects that the pressure sensor connected to the processor detects liquid or foreign matter and thus there is pressure feedback, but does not detect that multiple electrodes detect conductive liquid and thus there is current feedback, it determines that non-conductive liquid or other foreign matter that has a pressure effect on the pressure sensor is currently monitored. Then, the liquid monitoring device further activates the preset liquid level sensor through the processor to perform liquid level detection on the possible non-conductive liquid.

[0090] Alternatively, when the liquid monitoring device detects that the pressure sensor connected to the processor does not detect liquid or foreign matter and thus there is no pressure feedback, and detects that multiple electrodes do not detect conductive liquid and thus there is no current feedback, it immediately determines that no liquid or other foreign matter that has a pressure effect on the pressure sensor is currently being monitored.

[0091] The expanded contents of the specific implementation manner of the liquid monitoring device of the present invention are basically the same as the various embodiments of the above-mentioned electrode-based liquid monitoring method, and will not be elaborated here.

[0092] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which an electrode-based liquid monitoring program is stored. When the electrode-based liquid monitoring program is executed by a processor, the steps of the electrode-based liquid monitoring method described below are implemented.

[0093] The various embodiments of the robot and computer-readable storage medium of the present invention may refer to the various embodiments of the electrode-based liquid monitoring method of the present invention, which will not be described in detail here.

[0094] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
