High frequency interference-elimination type water level pre-warning system based on internet of things technology

Abstract

The invention discloses a high frequency interference-elimination type water level pre-warning system based on internet of things technology, which is characterized by including a single chip microcomputer, a modulus conversion chip and a signal processing unit which are connected to the single chip microcomputer respectively, a water level sensor which is connected to the modulus conversion chip, a wireless transmission unit which is connected to the signal processing unit and an upper computer which is connected to the wireless transmission unit through a wireless network. The high frequency interference-elimination type water level pre-warning system based on internet of things technology can process monitoring signals very well, thus making the monitoring signals received by the upper computer more stable, allowing workers to analyze river water levels more easily and accurately according to the monitoring signals, and improving the warning effect greatly.

Description

Technical field [0001] The invention relates to a water level early warning system, in particular to a high frequency interference elimination type water level early warning system based on the Internet of Things technology. Background technique [0002] Water conservancy monitoring equipment is an indispensable equipment in water conservancy construction, and monitoring and early warning of river water level is an indispensable part of water conservancy flood control and flood fighting. With the continuous development of the Internet of Things technology, there has been a high-frequency interference elimination water level early warning system based on the Internet of Things technology. The water level early warning system can monitor the water level of the river in real time, and predict the possibility of flooding based on the monitoring results. Thus, emergency preparedness can be made before the flood occurs and losses can be reduced. However, the existing high-frequency in...
