FIG. 1 is a flow chart of a method of monitoring fluid level, as shown in FIG. 1, according to an embodiment of the application, the method comprising the steps of:
step S102, acquiring a hydraulic signal of a sensor of an area to be tested, wherein the sensor is arranged at the bottom end of the area to be tested;
step S104, switching on a relay of at least one preset test point according to a hydraulic signal, wherein each preset test point corresponds to a preset depth value, a plurality of preset test points are respectively provided with relays with different switching-on thresholds, and the relays are switched on according to the relation between the hydraulic signal and the switching-on thresholds;
step S106, at least one preset depth value corresponding to a preset test point for switching on the relay is obtained;
step S108, determining the liquid level depth of the area to be tested according to at least one preset depth value.
In the embodiment of the application, a hydraulic signal of a sensor of an area to be tested is acquired, wherein the sensor is arranged at the bottom end of the area to be tested; switching on the relay of at least one preset test point according to the hydraulic signal, wherein each preset test point corresponds to a preset depth value, a plurality of preset test points are respectively provided with relays with different switching-on thresholds, and the relay is switched on according to the relation between the hydraulic signal and the switching-on thresholds; acquiring at least one preset depth value corresponding to a preset test point for switching on a relay; determining the liquid level depth of the area to be tested according to at least one preset depth value; the relay of the corresponding preset test point is triggered to be connected through the hydraulic signal, and the liquid level depth of the area to be tested can be determined based on the preset depth value corresponding to the preset test point which is connected through the relay, so that the technical effect of accurately determining the liquid level depth is realized, and the technical problem that the liquid level depth cannot be accurately detected in the prior art is solved.
In the above step S102, the hydraulic signal is an electric signal generated by the sensor under the action of the liquid pressure, wherein the liquid pressure is affected by the liquid depth, the deeper the liquid depth, the greater the hydraulic pressure at the liquid bottom, and the liquid depth can be determined based on the liquid pressure at the liquid bottom.
Alternatively, the sensor is a high-precision pressure sensor, and the greater the liquid pressure, the higher the potential of the hydraulic signal.
Optionally, the sensor may be a plurality of high-precision pressure sensors, and the plurality of sensors are all disposed at the bottom of the water level monitoring device, and the water level depth is comprehensively determined according to the pressure values collected by the plurality of sensors.
Optionally, determining the water level depth from the pressure values collected by the plurality of sensors includes: the water level depth is calculated from an average of the pressure values collected by the plurality of sensors.
Optionally, determining the water level depth from the pressure values collected by the plurality of sensors includes: and determining the credibility of the pressure values acquired by the plurality of sensors according to the variances of the pressure values acquired by the plurality of sensors.
Optionally, the sensor may be a plurality of switch sensors with fixed pressure thresholds, corresponding to different water level depths, and after the water level reaches the designated water level depth, the sensor corresponding to the pressure value triggers to generate a hydraulic signal, and the switch sensor with higher fixed pressure threshold sends out a higher potential of the hydraulic signal.
For example, the fixed pressure thresholds of the plurality of sensors may be set at 10cm depth pressure threshold intervals, such as a first sensor indicating a water level depth exceeding 10cm, a second sensor indicating a water level depth exceeding 20cm, and a third sensor indicating a water level depth exceeding 30cm, the first sensor being triggered and the second and third sensors not being triggered if the water level depth exceeding 10cm does not exceed 20cm (e.g., 15 cm); if the water level depth exceeds 20cm and does not exceed 30cm (such as 25 cm), the first sensor and the second sensor are triggered, and the third sensor is not triggered.
Optionally, in the case that the sensor is a switch sensor with a plurality of fixed pressure thresholds, the priority of the sensor may be determined according to the water level depth corresponding to the sensor, where the smaller the water level depth is, the higher the priority is; the highest level sensors are triggered sequentially in a priority order.
For example, the first sensor indicates a water level depth of 10cm, the second sensor indicates a water level depth of 20cm, the third sensor indicates a water level of 30cm, and the second sensor is allowed to be triggered only if the first sensor has been triggered; otherwise, the second sensor is not allowed to be triggered under the condition that the first sensor is not triggered; and a third sensor is allowed to be triggered only if the first sensor and the second sensor have been triggered; otherwise, the third sensor is not allowed to be triggered in case the first sensor or the second sensor is not triggered.
Alternatively, in the case where the sensor is a plurality of fixed pressure threshold switch sensors, each priority sensor is connected through AND gate logic, and the priority sensor is allowed to be triggered only if the previous priority sensor has been triggered.
According to the embodiment of the application, the sensors with various priorities are connected through the AND gate logic circuit, so that the sensors can only be triggered step by step, but not by skip, and the occurrence of false alarm of the sensors is avoided.
In step S104, the plurality of preset test points may be set at equal depth intervals, so that each preset test point may be triggered by pressure signals with different electric potentials, where each preset test point is provided with a corresponding relay, and the relay may receive a hydraulic signal, and control the relay corresponding to each preset test point to be turned on or off under the triggering of the hydraulic signal.
In the above step S104, the on threshold may be a threshold of an electric signal, such as a potential threshold, and in the case where the potential of the hydraulic signal is higher than the potential of the on threshold, the relay corresponding to the on threshold is turned on.
Optionally, in the case that the preset test point is triggered, the corresponding light emitting diode may be turned on, or the liquid depth value corresponding to the preset test point may be displayed.
Optionally, in the case that the sensor is a switch sensor with multiple fixed pressure thresholds, the multiple sensors are connected with each preset test point through a bus, and because the pressure thresholds triggering different sensors are different, the potentials of hydraulic signals generated by different sensors are different, the hydraulic signals with different potentials are connected with relays of multiple preset test points through the same bus, and the relays corresponding to different preset test points can be respectively connected based on the hydraulic signals with different potentials.
Optionally, in the case that the sensor is a switch sensor with a plurality of fixed pressure thresholds, each sensor may be connected with a preset test point in a one-to-one correspondence manner through a dedicated connection line, and after the sensor is triggered, a hydraulic signal is generated, and the hydraulic signal may be transmitted to a corresponding preset test point through the dedicated connection line, so as to switch on a relay corresponding to the preset test point.

Optionally, the number of preset test points connected with the water pump is two, including: the device comprises a first preset test point and a second preset test point, wherein a relay of the first preset test point is a starting relay, a relay of the second preset test point is an ending relay, a switching-on threshold of the starting relay is higher than a switching-on threshold of the ending relay, a preset depth value of the first preset test point is higher than a preset depth value of the second preset test point, and a water pump is started to pump out liquid in a region to be tested under the condition that the liquid level depth is higher than the preset depth value of the first preset test point; and under the condition that the liquid level depth is gradually reduced until the liquid level depth is lower than the preset depth value of the second preset test point, the water pump is turned off.
Optionally, the alarm device may be a buzzer, and when the liquid level depth is higher than a preset test point corresponding to the alarm device, the relay of the preset test point is turned on, and the buzzer is electrified to alarm.
As an alternative embodiment, determining the liquid level depth of the area to be tested from the at least one preset depth value comprises: determining a maximum depth value of the at least one preset depth value; the maximum depth value is taken as the liquid level depth of the area to be tested.
For example, the preset depth value of the preset test point includes: 10cm, 20cm, 30cm, 40cm, etc., if the relay on test point is determined to include: 10cm, 20cm and 30cm, the liquid level depth of the area to be tested is determined to be 30cm.

According to the embodiment of the application, as the liquid level depth increases, the hydraulic signals also increase gradually, and the relays of all preset test points are gradually switched from an off state to an on state; as the liquid level depth is reduced, the hydraulic signals are gradually reduced, and the relays of all preset test points are gradually switched from an on state to an off state; when the relay is switched from the off state to the on state, whether the relay is switched from the off state to the on state can be directly determined directly based on the hydraulic signal and the on threshold of the relay; under the condition that the relay is switched from the on state to the off state, the difference value between the hydraulic signal and the on threshold value of the relay needs to be calculated, and whether the relay is switched from the on state to the off state or not is determined based on the difference value and a preset difference value, so that a circuit system is protected, and the circuit is prevented from being damaged due to frequent starting of small-amplitude water level fluctuation.
Optionally, after acquiring the initial relay state of the relay of the at least one preset test point, the method further comprises: and determining the second relay with the initial relay state being in the on state, and switching the second relay from the on state to the off state if the second relay does not receive the hydraulic signal which is larger than the on threshold value within a preset period of time.
