Embodiment Construction

[0045] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0046] The invention relates to a monitoring system for measuring ammonia nitrogen content in fishery breeding water. The purpose of the method is to overcome the problems that the existing ammonia nitrogen analyzer needs to be operated manually, the precision and speed are slow, the error of the ammonia nitrogen measuring instrument is large, the failure rate is high, and the maintenance cost is large. An ammonia nitrogen on-line monitoring system is provided, which is used to accurately and timely on-line monitor the ammonia nitrogen content in aquaculture water.

Abstract

The invention discloses an ammonia nitrogen on-line monitoring system and a method thereof. The system comprises a sampling module used for obtaining a sample to be detected in a current pond; a signal detection module used for mixing the sample to be detected and a reagent NaOH solution, detecting an ammonia nitrogen concentration signal, a PH value signal and a temperature value signal of the collected water body; a signal processing module used for respectively processing the ammonia nitrogen concentration signal, the PH value signal and the temperature value signal of the collected water body detected by the signal detection module to obtain an ammonia nitrogen concentration voltage signal, a PH value voltage signal and a temperature value voltage signal; and a calculating control module used for calculating the ammonia nitrogen content in the collected water body through a data fusion algorithm according to the ammonia nitrogen concentration voltage signal, the PH value voltage signal and the temperature value voltage signal sent from the signal processing module. The apparatus has a simple structure, and can accurately and timely monitor the ammonia nitrogen content in culture water.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to an ammonia nitrogen online monitoring system and method. Background technique [0002] The ammonia nitrogen content of water refers to the free state ammonia NH 3 and ammonium ion NH 4 + The total amount of combined nitrogen in the form is an important indicator reflecting water body pollution. When the free ammonia nitrogen reaches a certain concentration, it has a toxic effect on aquatic organisms. The solubility of ammonia nitrogen in water is different at different pH values. When the pH value When it is high, the proportion of free ammonia is high. The concentration of ammonia nitrogen reflects the influence of water environment (NH 3 ) and (NH 4 + ), in order to ensure the growth of aquatic organisms in the aquaculture water, it is necessary to measure the concentration of ammonia nitrogen in the water quality. [0003] There are many methods for measuring ammon...
