Environment-friendly water quality monitoring system and monitoring method based on Internet of Things

Abstract

The environment-friendly water quality monitoring system comprises an online water quality monitor body, a GPRS (General Packet Radio Service) module, a solar cell panel, a storage battery, a power switch, a buoy and an electric propeller, the device further comprises a transmitting and receiving mechanism, a limiting mechanism and a switching circuit. The on-line water quality monitor body, the electric propeller, the solar cell panel and the launching mechanism are mounted on the buoy; the receiving mechanism comprises an infrared receiving module, a convex lens, an electric telescopic rod, a photoelectric switch and an output sub-circuit which are installed together, the limiting mechanism comprises a trigger sub-circuit, a reed switch, a magnet, a GPRS module, a storage battery and a power switch which are installed together, and the output sub-circuit, the trigger sub-circuit and a switching circuit are installed in an electric cabinet. And the circuit is electrically connected with other electrical components. The monitoring method of the environment-friendly water quality monitoring system based on the Internet of Things comprises five steps. Cost is saved, the electric propeller blades can be prevented from being damaged, and synchronous height changes of the transmitting end and the receiving end can be adjusted according to water level changes.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring equipment and application methods, in particular to an environment-friendly water quality monitoring system and monitoring method based on the Internet of Things. Background technique [0002] In the environmental protection department, etc., it is often necessary to monitor the water quality of the river with an online water quality monitor. The online water quality monitor transmits the monitored water quality data through the GPRS module in real time, providing technical support for the remote personnel to grasp the specific data of the on-site water quality. In practice, in order to achieve sampling and monitoring of the water quality at the center of the river, in the prior art, an online water quality monitor is installed on a floating body, and then the entire monitoring equipment is transported by boat and set up at the center of the river for monitoring. [0003] In order...

AI Technical Summary

Problems solved by technology

However, the water level of the river is changing dynamically. The buoyancy equipment, the infrared emitting mechanism and the infrared receiving mechanism are respectively installed on the river bank and the floating body in the river. Such as equipment with a focusing lens, but the focusing degree of the focusing lens cannot be infinite. When the river water level fluctuates too much, it will cause the infrared rays emitted by the infrared emitting mechanism and the infrared receiving mechanism to be unable to receive, which will cause the overall equipment to be abnormal. Work

In addition, its power supply is supplied by an external power supply. Since it is often inconvenient to install cables in river monitoring areas, it will bring inconvenience to use and increase capital investment.

Finally, it has no water level control function. When the water level of the river is lower than a certain level, when the propeller touches the bottom of the river, if the control circuit controls the rotation of the blades, the blades will collide with the river bed and be damaged.
