step S106, acquiring at least one preset depth value corresponding to a preset test point of relay connection;
and 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 invention, a hydraulic signal of a sensor of a to-be-tested area is obtained, wherein the sensor is arranged at the bottom end of the to-be-tested area; the method comprises the steps that relays of at least one preset test point are connected according to a hydraulic signal, wherein each preset test point corresponds to a preset depth value, the plurality of preset test points are respectively provided with the relays with different connection threshold values, and the relays are connected according to the relation between the hydraulic signal and the connection threshold values; acquiring at least one preset depth value corresponding to a preset test point of relay connection; 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 switched on 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 of the relay switching on, so that the technical effect of accurately determining the liquid level depth is achieved, 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 pressure signal is an electric signal generated by the sensor under the action of the liquid pressure, wherein the liquid pressure is influenced by the liquid depth, and the deeper the liquid depth, the higher the hydraulic pressure at the bottom of the liquid, and the liquid depth can be determined based on the liquid pressure at the bottom of the liquid.
Optionally, the sensor is a high-precision pressure sensor, and the higher 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 determined comprehensively according to the pressure values collected by the plurality of sensors.
Optionally, the step of comprehensively determining the water level depth according to the pressure values collected by the plurality of sensors includes: and calculating the water level depth according to the average value of the pressure values acquired by the plurality of sensors.
Optionally, the step of comprehensively determining the water level depth according to the pressure values collected by the plurality of sensors includes: and determining the reliability of the pressure values acquired by the plurality of sensors according to the variance of the pressure values acquired by the plurality of sensors.
Alternatively, the sensor may be a plurality of switch sensors with fixed pressure thresholds, each of the switch sensors corresponds to a different water level depth, after the water level reaches a specified water level depth, the sensor corresponding to the pressure value triggers generation of a hydraulic signal, and the higher the fixed pressure threshold is, the higher the potential of the hydraulic signal sent by the switch sensor is.
For example, the fixed pressure thresholds of the plurality of sensors may be set at intervals of 10cm depth pressure thresholds, such as a first sensor indicating that the water level depth exceeds 10cm, a second sensor indicating that the water level depth exceeds 20cm, and a third sensor indicating that the water level depth exceeds 30cm, where if the water level depth exceeds 10cm and does not exceed 20cm (e.g., 15cm), the first sensor is triggered, and the second sensor and the third sensor are not triggered; if the water level depth exceeds 20cm and does not exceed 30cm (such as 25cm), 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, wherein the smaller the water level depth, the higher the priority; and sequentially triggering the sensors at the highest level according to the priority order.
For example, a first sensor indicates a water level depth of 10cm, a second sensor indicates a water level depth of 20cm, and a third sensor identifies a water level of 30cm, the second sensor being 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; the third sensor is then allowed to be triggered only if the first and second sensors have been triggered; otherwise the third sensor is not allowed to be triggered in case either the first or the second sensor is not triggered.
Alternatively, in the case of a plurality of fixed pressure threshold switch sensors, the sensors of each priority are connected to an and logic circuit, and the sensor of the priority is allowed to be triggered only when the sensor of the previous priority has been triggered.

In the above step S104, the on threshold may be a threshold of the 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, a relay corresponding to the on threshold is turned on.
Optionally, in a case where a preset test point is triggered, the corresponding light emitting diode may be turned on, or a liquid depth value corresponding to the preset test point may be displayed.
Optionally, in the case that the sensors are switch sensors with a plurality of fixed pressure thresholds, the plurality of sensors are connected to the preset test points through buses, and since the pressure thresholds triggering different sensors are different, the potentials of hydraulic signals generated by different sensors are also different, the hydraulic signals with different potentials are connected to the relays of the 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 a case that the sensor is a switch sensor with a plurality of fixed pressure thresholds, each sensor may be connected to the preset test point in a one-to-one correspondence manner through a dedicated connection line, a hydraulic signal is generated after the sensor is triggered, the hydraulic signal may be transmitted to the corresponding preset test point through the dedicated connection line, and a relay corresponding to the preset test point is turned on.
