Sensing water depth range-viewfinder and operation method thereof

Abstract

The invention discloses a sensing water depth range-viewfinder and an operation method thereof. The sensing water depth range-viewfinder comprises an indicator light, a humidity sensor, a marker post,a displacement sensor, an annular float and a power supply for supplying power. The indicator light is installed at the top of the marker post; and the humidity sensor is installed at the upper partof the marker post, the humidity sensor comprises a hygristor and an electromagnet used for controlling the displacement sensor, and the electromagnet is activated by output current of the hygristor.The displacement sensor is installed at the lower part of the marker post and extends outwards, the displacement sensor comprises a slide rheostat, a sender unit and an ampere meter, the annular floatis installed at the lower part of the marker post in a sleeving mode, the slide rheostat is connected with the annular float, the annular float pulls the slide rheostat to change a resistance value,the current output by the slide rheostat is converted into depth through the ampere meter, the displacement sensor judges whether the measured depth is more than the height of an automotive chassis ornot, and if the depth is more than the height of the automotive chassis, a danger signal is sent to a vehicle owner by the sender unit. The sensing water depth range-viewfinder and the operation method can accurately detect the depth of a flooded road section, and a flameout accident caused by travelling in water of a vehicle is avoided.

Description

technical field [0001] The invention relates to the technical field of surveying, in particular to a sensor-type water depth rangefinder and an operating method thereof. Background technique [0002] Heavy rains often cause standing water. When encountering heavy rain, car owners often try to forcefully pass through the waterlogged section because they underestimate the depth of the ponded water because they lack an accurate method to measure the depth of the ponded water, which eventually causes the car to stall in the rainstorm. [0003] Currently, car owners can use information such as weather forecasts to determine whether to drive or not. However, there is a lack of a technology with strong real-time performance and high measurement accuracy to judge the depth of waterlogging so as to decide whether it is safe to drive through the waterlogging section. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prio...
