Abstract

The invention provides a self-powered multi-parameter water quality monitor based on an NB-IOT (Narrow Band Internet of Things). The self-powered multi-parameter water quality monitor comprises a master control chip, an NB-IOT communication module, a multi-parameter water quality detection module and a self-powered device used for providing a power supply, wherein the master control chip is respectively connected with the NB-IOT communication module and the multi-parameter water quality detection module; the master control chip outputs a parameter detection instruction to the multi-parameter water quality detection module according to an operation instruction which is received by the NB-IOT communication module and sent from cloud; a water quality result returned from the multi-parameter water quality detection module is processed and is uploaded to the cloud through the NB-IOT communication module.

Description

technical field [0001] The invention relates to a water quality monitoring device, in particular to a NB-IOT-based self-powered multi-parameter water quality monitor. Background technique [0002] The multi-parameter water quality monitor realizes simultaneous online monitoring of multiple different parameter values ​​through optional sensors, including temperature / PH / conductivity / dissolved oxygen / turbidity / sludge concentration / ammonia nitrogen concentration, etc. It is mainly used in sewage plants, tap water Factory, water station, surface water, industry and other fields. Traditional multi-parameter water quality monitors need to be powered by AC power, and the collected monitoring data is uploaded to external devices through MODBUS, RS485 and other wired communication methods. It is difficult to use in places where there is no mains power or where wiring is inconvenient. [0003] In order to solve the above existing problems, people have been seeking an ideal technical s...
