Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a liquid monitoring method based on an electrode according to a first embodiment of the present invention.
While a logical sequence is shown in the flow chart, in some cases, the steps shown or described may be performed in a different sequence than that shown or described herein.
It should be noted that the implementation subject of the various embodiments of the electrode-based liquid monitoring method of the present invention may be a liquid monitoring device, the liquid monitoring device includes a plurality of electrodes, and the number of the plurality of electrodes is greater than two, and furthermore, the liquid monitoring device may be conventionally controlled by an automatic control program. The types and types of the liquid monitoring device and the specific implementation details are not limited in each embodiment.
In the present embodiment, the electrode-based liquid monitoring method includes the following steps S10-S40:
step S10 of detecting whether there is current feedback detected based on the plurality of electrodes and whether there is preset pressure feedback;
the liquid monitoring device detects whether the electrodes detect liquid through a built-in processor respectively connected with the electrodes so as to have current feedback, and detects whether preset pressure feedback exists through the processor.
In this embodiment, the preset pressure feedback is a pressure sensor preset by the liquid monitoring device and connected to the processor, and when it is detected that the surface of the pressure sensor is covered with liquid (including conductive liquid and non-conductive liquid) or other solid foreign matter, the pressure feedback is output to the processor.
Further, in a possible embodiment, the liquid monitoring device further comprises a pressure sensor, and the pressure sensor is also connected with the processor of the liquid monitoring device. The step of "detecting whether there is the preset pressure feedback" in the step S10 may include:
step S101, when the plurality of electrodes are synchronously or asynchronously started to detect whether the current feedback exists, the pressure sensor is started to detect whether the preset pressure feedback exists.
The liquid monitoring device can simultaneously control to open the plurality of electrodes and the pressure sensor through the processor to respectively detect, so as to detect whether current feedback returned by the plurality of electrodes exists and whether preset pressure feedback returned by the pressure sensor exists, or the liquid monitoring device can also control to open the plurality of electrodes (or the pressure sensor) through the processor to detect whether current feedback (or preset pressure feedback) exists or not, and then control to open the pressure sensor (or the plurality of electrodes) to detect whether preset pressure feedback (or current feedback) exists or not.
It should be noted that, in this embodiment, the preset pressure sensor of the liquid monitoring device may be any type of pressure sensor on the market, which is capable of detecting the pressure of the liquid or other foreign matter covered thereon based on its own working principle, and sending pressure feedback to the connected processor when detecting that the liquid or other foreign matter is covered thereon. It should be understood that the pressure sensors that the liquid monitoring device can be preset and connected to the process can be of different types and numbers in different possible embodiments based on different design requirements of practical applications, and the liquid monitoring method based on the electrode of the present invention is not limited to the specific type of the pressure sensor and the details of the detection operation principle.
Specifically, for example, referring to the application flow shown in fig. 2, when the liquid monitoring device reaches a predetermined detection time, the processor controls the pressure sensor to start to detect first, so as to determine whether the pressure sensor detects liquid or foreign matter and has pressure feedback, and if it is determined that the pressure sensor has no pressure feedback, the processor immediately controls the pressure sensor to enter a sleep state, so as to restart the detection when the predetermined detection time is reached next time. Or if the pressure sensor is judged to have pressure feedback, the processor further controls to start the electrodes for liquid detection, judges whether current feedback returned by the electrodes when the conductive liquid is detected exists or not, and further controls the electrodes and the pressure sensor to enter a dormant state again when the current feedback is judged not to exist.
In this embodiment, the liquid monitoring device further uses a newly added pressure sensor to assist the plurality of electrodes in the process of performing liquid monitoring through the plurality of electrodes (more than two), so that compared with the conventional double-electrode measurement mode, the liquid monitoring mode of the present invention is more accurate and sensitive, and the monitoring efficiency is higher.
Step S20, if the current feedback is detected to exist, determining that the conductive liquid is monitored and starting liquid level detection;
when the liquid monitoring device detects that a plurality of electrodes connected with the processor detect liquid, so that current feedback exists, the liquid monitoring device directly determines that the conductive liquid is monitored at present and synchronously starts a preset liquid level sensor to carry out liquid level detection on the conductive liquid.
It should be noted that, in this embodiment, the liquid level sensor preset in the liquid monitoring device may be any type of liquid level sensor on the market, and the liquid level sensor can detect liquid level data (for example, liquid level height and the like) of liquid covered on the liquid level sensor based on its own working principle, and report the liquid level data to a connected processor when the liquid level data is detected, or can 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, depending on the design requirements of the actual application, the liquid level sensors that the liquid monitoring device can be preset and connected to the process can be of different types or even numbers in different possible embodiments, and the liquid monitoring method based on the electrodes of the present invention is not limited to the specific type of the liquid level sensors and the details of the detection operation principle.
Furthermore, it should be understood that, based on different design requirements of practical applications, in different possible embodiments, the liquid monitoring device may preset different sensors in addition to the preset pressure sensor and the liquid level sensor, and of course, the liquid monitoring device may also preset different sensors based on other detection requirements.
Step S30, if it is detected that only the preset pressure feedback exists, determining that non-conductive liquid or foreign matter is monitored and starting liquid level detection;
when the liquid monitoring device detects that the pressure sensor connected with the processor detects liquid or foreign matters so as to have pressure feedback, but does not detect current feedback that a plurality of electrodes detect conductive liquid so as to have pressure feedback, the liquid monitoring device determines that non-conductive liquid or other foreign matters having pressure influence on the pressure sensor are currently monitored, and then the liquid monitoring device further starts a preset liquid level sensor through the processor to carry out liquid level detection on the non-conductive liquid possibly existing.
Further, in a possible embodiment, the step of "turning on the liquid level detection" in the step S20 or the step S30 may include:
and step A, starting the liquid level sensor to detect the liquid level of the conductive liquid level or the non-conductive liquid.
The liquid level monitoring device is used for controlling and starting a preset liquid level sensor through the processor to detect the liquid level of the conductive liquid when detecting that the electrodes connected with the processor detect the liquid so that current feedback exists and determining that the conductive liquid is monitored currently. Or,
when the liquid monitoring device detects that the pressure sensor connected with the processor detects liquid or foreign matters so as to have pressure feedback, but does not detect current feedback that a plurality of electrodes detect conductive liquid so as to have current feedback, so that the liquid monitoring device determines that non-conductive liquid or other foreign matters having pressure influence on the pressure sensor are currently detected, the preset liquid level sensor is further started through the processor to carry out liquid level detection on the non-conductive liquid possibly existing.
Specifically, for example, referring to the application flow shown in fig. 2, when the liquid monitoring device determines that there is pressure feedback in the preset pressure sensor, the processor further controls to turn on the plurality of electrodes for liquid detection, and when it determines that there is current feedback of current returned by the plurality of electrodes when the conductive liquid is detected, further controls to turn on the preset liquid level sensor for measuring the conductive liquid detected by the plurality of electrodes, so that the liquid level sensor returns liquid level data such as the measured liquid level height of the conductive liquid to the processor (shown in the figure), and the processor finishes the liquid level data and then outputs a predetermined result to a service system or a device connected to the liquid monitoring device.
Further, in a possible embodiment, after the step of "determining that the non-conductive liquid or the foreign object is detected and the liquid level detection is started" in the step S30, the method for monitoring the liquid based on the electrode according to the present invention may further include:
step S50, if the liquid level sensor detects liquid level data, determining to monitor the non-conductive liquid and reporting the liquid level data;
when the liquid monitoring device detects that a pressure sensor connected with the processor detects liquid or foreign matters so as to have pressure feedback, but does not detect current feedback that a plurality of electrodes detect conductive liquid so as to have pressure influence, the liquid monitoring device determines that non-conductive liquid or other foreign matters having pressure influence on the pressure sensor are monitored at present, and further starts a preset liquid level sensor through the processor to detect the liquid level of the non-conductive liquid possibly existing, and if the liquid level sensor detects and feeds back liquid level data to the processor, the liquid monitoring device firstly determines that the non-conductive liquid is monitored at present and reports the liquid level data returned by the liquid level sensor.
It should be noted that, in this embodiment, the liquid level monitoring device may also be connected to other service systems or devices in advance, so as to report the monitored liquid level data to the other service systems or devices in real time for performing corresponding service processing. Specifically, for example, the liquid level monitoring device may be connected to a system for monitoring and managing a road network in advance, so that after the liquid level monitoring device monitors liquid level data, the liquid level data is reported and transmitted to the system in real time, and the system manages and controls the road network based on the liquid level data.
Further, in another possible embodiment, after the step of "determining that the non-conductive liquid or the foreign object is detected and the liquid level detection is started" in the step S30, the method for monitoring the liquid based on the electrode according to the present invention may further include:
and step S60, if the liquid level sensor detects liquid level data, determining that the foreign matter is monitored and reporting preset prompt information.
It should be noted that, in this embodiment, the preset prompting information may be a prompting information for prompting a relevant service system or a worker, where the detection accuracy may be affected by the fact that a sensor of the current liquid level monitoring device is covered by a foreign object, and therefore needs to be maintained in time.
The liquid monitoring device is used for monitoring the liquid level of the liquid when detecting that the pressure sensor connected with the processor detects liquid or foreign matters so as to have pressure feedback, but not detecting current feedback when the plurality of electrodes detect conductive liquid so as to have current feedback, thereby determining that a non-conductive liquid or other foreign object having a pressure effect on the pressure sensor is currently being detected, when the processor further starts a preset liquid level sensor to detect the liquid level of the non-conductive liquid possibly existing, if the liquid level sensor does not detect the liquid level data, the liquid monitoring device determines that the non-conductive liquid is not currently being monitored, but that the pressure sensor has foreign matter having pressure influence, furthermore, the liquid level monitoring device reports to other business systems, devices or workers connected in advance that the detection accuracy is possibly affected by the fact that the sensor is covered by foreign matters, so that prompt information needs to be maintained in time.
In this embodiment, when the liquid monitoring device monitors and determines that the preset pressure sensor is covered with the foreign matter with pressure influence, the sensor of the current liquid level monitoring device is immediately output to a pre-connected service system or a worker, and the detection accuracy is possibly influenced by the foreign matter coverage, so that prompt information is required to be maintained in time.
In step S40, if the current feedback and the preset pressure feedback are not detected, it is determined that no liquid is detected.
The liquid monitoring device immediately determines that no liquid or other foreign matter having pressure influence on the pressure sensor is currently monitored when detecting that the pressure sensor connected to the processor does not detect liquid or foreign matter and thus no pressure feedback exists, and detecting that the plurality of electrodes also do not detect conductive liquid and thus no current feedback exists.
In this embodiment, the liquid monitoring device detects whether the electrodes detect liquid through a built-in processor respectively connected to the electrodes, so that current feedback exists, and detects whether preset pressure feedback exists through the processor; when the liquid monitoring device detects that a plurality of electrodes connected with the processor detect liquid so that current feedback exists, the liquid monitoring device directly determines that the conductive liquid is monitored at present and synchronously starts a preset liquid level sensor to carry out liquid level detection on the conductive liquid; or when the liquid monitoring device detects that the pressure sensor connected with the processor detects liquid or foreign matters so as to have pressure feedback, but does not detect current feedback that a plurality of electrodes detect conductive liquid so as to have pressure feedback, the liquid monitoring device determines that non-conductive liquid or other foreign matters having pressure influence on the pressure sensor are currently monitored, and then the liquid monitoring device further starts a preset liquid level sensor through the processor to carry out liquid level detection on the non-conductive liquid possibly existing; still alternatively, the liquid monitoring device determines that no liquid or other foreign matter having pressure influence on the pressure sensor is currently monitored when detecting that the pressure sensor connected to the processor does not detect liquid or foreign matter, so that no pressure feedback exists, and detecting that the plurality of electrodes also do not detect conductive liquid, so that no current feedback exists.
Compared with the existing mode of performing liquid detection by adopting double electrodes, the liquid detection method and the liquid detection device have the advantages that the pressure generated by the liquid and the current detected by the multiple electrodes are detected, so that the liquid is monitored by combining the pressure and the current, the monitoring for the non-conductive liquid can be realized under the assistance of pressure feedback, the monitoring stability for the liquid is greatly improved, in addition, the current detection is performed by arranging the multiple electrodes with the number larger than two, the problem that the liquid detection is difficult to perform again after one electrode is corroded in the double-electrode detection process is solved, and the liquid detection accuracy and reliability are effectively ensured.

Or when the liquid monitoring device detects that the pressure sensor connected with the processor detects liquid or foreign matters so as to have pressure feedback, but does not detect current feedback that the electrodes detect conductive liquid so as to have pressure feedback, the liquid monitoring device determines that non-conductive liquid or other foreign matters having pressure influence on the pressure sensor are currently detected, and then the liquid monitoring device further starts a preset liquid level sensor through the processor to carry out liquid level detection on the possibly existing non-conductive liquid.
Still alternatively, the liquid monitoring device determines that no liquid or other foreign matter having pressure influence on the pressure sensor is currently monitored when detecting that the pressure sensor connected to the processor does not detect liquid or foreign matter, so that no pressure feedback exists, and detecting that the plurality of electrodes also do not detect conductive liquid, so that no current feedback exists.
