LoRa-based river water quality monitoring system

Abstract

The invention discloses a river water quality monitoring system based on LoRa. The system comprises a floating detection terminal, a LoRa gateway, a far-end server and a monitoring terminal, wherein the floating detection terminal comprises a main control module, a LoRa communication module, a GPS module, a power supply module, a sensor module, a fixing anchor and a floating plate, wherein the sensor module comprises a hollow telescopic rod, a sealing shell, a PH sensor, a COD sensor, a dissolved oxygen sensor, an ammonia nitrogen sensor and a total phosphorus sensor. The floating detection terminal collects data and transmits the data to a far-end server through the LoRa gateway, and the monitoring terminal receives the data processed by the far-end server, carries out the visual displayof the data, and gives a threshold monitoring instruction. The system is advantaged in that a problem of difficulty in wide coverage and long-term effective water quality monitoring is solved, and stability and safety of data transmission are ensured.

Description

technical field [0001] The invention relates to the field of surface water monitoring, in particular to a LoRa-based river water quality monitoring system. Background technique [0002] So far, my country has built a monitoring system covering all major areas of the country, but most of them are manual monitoring stations, with a heavy workload, and the use of chemical reagents for detection is likely to cause secondary pollution, making real-time monitoring impossible for a long time. Moreover, at present, water quality monitoring stations are mostly transmitted by the operator's network, and its application range is limited. The cost of long-distance transmission in the field is too high, and it can only meet the water quality monitoring of some water areas, and cannot realize regional networking. An important means for the construction of water ecological civilization requires the establishment of a water quality monitoring network with low power consumption, wide coverag...
