External power supply type riverbed water level centralized monitoring system based on Internet of Things

Abstract

The invention discloses an externally powered riverbed water level centralized monitoring system based on the Internet of Things, wherein, the surface of the water level pole is provided with a limit groove along the axial direction, and one end of the floating block is placed in the limit groove and can be placed in the limit groove. The water level sensor is used to identify the scale line of the water level pole and convert the distance information into an electrical signal. A battery is installed in the housing of the water level sensor, and the signal output end of the water level sensor is connected to the transmitting antenna through a wireless transmission circuit. The transmitting antenna is simultaneously connected to the receiving antenna and the management server through wireless communication, the signal output end of the receiving antenna is connected to the signal input end of the controller, and the signal output end of the controller is connected to the control end of the motor. In the invention, the water level sensor, the floating block and the water level pole are bound together, and the water level sensor detects the water level information of the river bed in real time, and both the management server and the controller can obtain the information, and adjust the height of the gate through the motor in real time, which is convenient for management.

Description

technical field [0001] The invention relates to a river bed water level detection system, in particular to an externally powered river bed water level centralized monitoring system based on the Internet of Things. Background technique [0002] With the rapid development of modern agriculture, water conservancy construction and water resource management are becoming more and more important. Due to changes in the global climate, under extreme weather conditions, disasters such as droughts and floods frequently occur in many places, and the water levels in many rivers and lakes distributed in vast wild places fluctuate greatly. More devices for measuring and reporting water levels are required to monitor the changing conditions. water level. At present, most of the water level detection of riverbeds is still carried out manually. By directly reading the numbers of water level poles or scales to understand the water level, this kind of management is not only time-consuming and ...

AI Technical Summary

Problems solved by technology

At present, most of the water level detection of riverbeds is still carried out manually. By directly reading the numbers of water level poles or scales to understand the water level, this kind of management is not only time-consuming and laborious, but also difficult for managers to quickly and real-time understand the water levels of different riverbeds, which is not conducive to Holistic management of water resources
