Non-contact water level detector and water level detection method

Abstract

The invention discloses a noncontact water level detector and a water level detecting method. The water level detector comprises an ultrasonic probe, a control unit and a remote communication module. The ultrasonic probe is used for reading water level data and transmitting the water level data to the control unit. The control unit is used for determining whether the water level data exceed a preset threshold and transmits an alarm signal when a determining result is yes. The remote communication module is used for transmitting the alarm signal to outside. The control unit is also used for transmitting current water level data to the remote communication module. The remote communication module is also used for transmitting current water level data to outside. Compared with the prior art, the ultrasonic probe has advantages of high detecting accuracy and high reliability; and furthermore rusting of the probe caused by dipping into water is prevented, thereby prolonging service life. Additionally, through adding the remote communication module which can perform alarming in time and furthermore can actively report the water level data, thereby facilitating a user to perform operations such as water discharging, and preventing flooding at positions of road, garage, etc.

Description

technical field [0001] The invention relates to the field of water level detection, in particular to a non-contact water level detector and a water level detection method. Background technique [0002] In recent years, my country has been affected by extreme weather, with frequent rainstorms in various places, and the problem of urban waterlogging is becoming more and more serious. In many cities, roads are flooded and garages are flooded during heavy rains. In 2012, five vehicles were flooded in a heavy rainstorm in Beijing, and one of the private car owners died. In Zhejiang and Guangzhou, underground garages were also flooded, causing serious damage to properties and private car owners, and the insurance industry even worse. Is to take the opportunity to launch the relevant insurance business. [0003] When the urban drainage system cannot quickly solve the waterlogging problem, timely monitoring and early warning of possible flooded areas is very important. For the are...
