Problems solved by technology

But this kind of online monitoring instrument is also very expensive, and the input cost of multi-point continuous automatic monitoring is very high
[0005] At present, more than 80% of the current aquaculture in our country is still based on pond aquaculture. Pond aquaculture has a large water surface and a wide area. The water quality online monitoring system used in industrial aquaculture workshops and aquariums is not suitable for outdoor pond aquaculture, and the high The monitoring cost does not match the input and output levels of the existing farming model, and cannot be popularized and applied in large-scale intensive pond farming water body monitoring
[0006] At present, the sampling and monitoring methods of pond aquaculture water quality in our country are still in the original stage of collecting with hand-held test tubes and then sending them to the laboratory for laboratory analysis. Real-time, online, and automatic monitoring of aquaculture water cannot be carried out. There is a certain delay, and after the water samples are transported for a long distance, the accuracy of the test data cannot be guaranteed. The current automatic water quality monitoring system is still blank in the application of outdoor pond culture.

Abstract

The invention discloses a method and a system for sampling aquaculture waters in ponds in real time. The method comprises that: a suite of data acquisition units orderly acquire a plurality of paths of fed samples of the different ponds and different sampling points, namely, orderly sample and monitor the second path and the next plurality of paths of fed samples after finishing sampling and monitoring the first path of fed samples, and start from the first path to perform the next round of sampling and monitoring after the first round of sampling and monitoring is finished; and the data acquisition units transmit monitoring data obtained by the sampling of each round and each path to a central control system in real time, wherein the sampling and monitoring data comprises the concentration of dissolved oxygen DO, a pH value, salinity Sal and temperature Tem. The method and the system have the characteristics of low input cost and good economical efficiency, are specifically suitable for aquaculture in the ponds, and can fully ensure that every time sampling data represents the actual conditions of the aquaculture waters in real time due to the adoption of the monitoring mode of in-vicinity sampling and monitoring and data remote transmission, enable managers to timely master real-time water quality data and take corresponding measures, and reduce the damage of the quality change of the aquaculture waters to aquatic products.

Description

technical field [0001] The invention relates to a real-time online sampling method for water quality, in particular to a pond culture water body. Background technique [0002] The real-time automatic monitoring technology of water quality depends on the development of automation technology, information technology and instrument technology, especially the development level of online water chemistry instruments that can work continuously under field conditions for a long time. In Europe, America, Japan and other countries, portable water quality monitors were sold in the 1970s, but they belonged to instantaneous measuring instruments, which can only measure the instantaneous value of water quality parameters, with great uncertainty and chance. [0003] The continuous multi-parameter water quality measuring instrument was only used in the 1980s. my country established the first continuous automatic monitoring system for water quality in 1988. Temperature, conductivity, turbidit...
