Real-time monitoring method and system for coastal red tide based on LoRa

Abstract

The invention provides a real-time monitoring method and system for coastal red tide based on LoRa, and belongs to the field of marine environment protection. The real-time monitoring method comprisesa data collection step in which terminal equipment collects initial data and uploads the initial data to a control center; a model extraction step in which the control center obtains data of each point, judges whether the data is reasonable data or not piece by piece, if not, discards the data, and if so, performs magnitude order standardization processing on the current data; a model matching step in which distance calculation is performed on the processed data and historical data to obtain a model with the space distance with the current data being the shortest, and a result corresponding to each single piece of data is confirmed; and a result determination step in which it is determined that a red tide occurs at present if data results of a plurality of continuous terminal devices showthat there is a red tide, and an alarm is given. The real-time monitoring method is low in cost, has good timeliness and can handle real-time conditions of the coastal red tide.

Description

technical field [0001] The invention relates to the field of sea area environmental protection, in particular to a LoRa-based offshore red tide real-time monitoring method and system. Background technique [0002] In the prior art, the detection of the offshore environment is carried out by robots carrying positioning systems to collect data, without processing the data, the accuracy is not high, and the abnormal data is not considered, and because the GPS positioning module and communication module are installed etc. have resulted in high cost and limited data transmission distance. As a low-cost, long-distance wireless transmission solution, LoRa technology has no specific plan for data collection, analysis and processing of offshore red tide. At the same time, real-time data of offshore red tide There is no specific corresponding plan for the actual scale of red tides. Contents of the invention [0003] In order to solve the problems in the prior art, the present inven...
