Problems solved by technology

[0004] However, sometimes when the water level rises, it is difficult to be detected by the water pressure sensor, resulting in a delayed response
Moreover, when the water level rises sharply, due to the undercurrent under the water surface, the water pressure acquisition may be inaccurate, resulting in deviations in the obtained current water level

Embodiment Construction

[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided.

[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention relates to a water level monitoring device. The water level monitoring device comprises an ultrasonic sensor, a water pressure sensor, a communication module and a power supply. When any one of an ultrasonic detector and a pressure probe detects that the water level rises, a microprocessor is activated, and the ultrasonic detector is extremely sensitive and can detect imperceptible changes, so that response of the device is more sensitive. In addition, the ultrasonic sensor monitors the water level through an echo location mode and is not affected by the water velocity and direction, and therefore water level information can be obtained more accurately. Furthermore, weighting treatment is conducted on the water level information obtained through the ultrasonic sensor and water level information obtained through the water pressure sensor to obtain a current water level, and therefore an error between the obtained current water level and the practical water level can be further reduced. Therefore, the water level monitoring device can effectively improve the reaction sensitivity and monitoring precision. In addition, the invention further provides a water level monitoring method and a well lid.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a water level monitoring device, method and well cover. Background technique [0002] Sewer pipes are an important part of urban drainage systems. In rainy days, the water level of the sewer pipes often increases due to the poor drainage of the sewer pipes, which may cause urban water accumulation. Therefore, when the water level exceeds the preset warning water level, an alarm is required. [0003] At present, the general monitoring device is to install a water pressure sensor on the well cover, monitor the water pressure through the water pressure sensor, and then obtain the current water level through the processing module, and then send an alarm according to the height of the water level. At present, a battery is generally used to power the monitoring device, and the power of the battery is limited. In order to improve the service life, the processor and other components...
