On-line fertilizer quality monitoring system

Abstract

The invention provides an on-line fertilizer quality monitoring system which comprises a sample conveyor belt, optical probes, a detection and control unit, V-shaped baffles and a main server monitoring device. A fertilizer sample is conveyed through the sample conveyor belt, the optical probes are installed over the sample conveyor belt, the V-shaped baffles are assembled at the front ends of the lower portions of the optical probes, and the V-shaped baffles and the lower sides of the optical probes are inserted into the fertilizer sample in the conveying process of the fertilizer sample on the sample conveyor belt; wireless communication modules are arranged in the detection and control unit, signals generated after the optical probes transmit collected spectra to the detection and control unit for light splitting and photoelectric conversion are transmitted to the wireless communication modules, the wireless communication modules comprise the CDMA communication module and the GSM communication module, and the main server monitoring device conducts modeling and quantitative analysis on the signals wirelessly received from the CDMA communication module or the GSM communication module. The on-line fertilizer quality monitoring system is convenient, efficient and accurate and cannot destroy the sample or consume chemical reagents or pollute the environment.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical fertilizer quality monitoring, in particular to an online monitoring system for chemical fertilizer quality. 【Background technique】 [0002] In my country's current fertilizer management regulations "Fertilizer Registration Measures", fertilizer refers to "used to provide, maintain or improve plant nutrition and soil physical, chemical properties and biological activities, can increase the output of agricultural products, or improve the quality of agricultural products, or enhance plant The quality of chemical fertilizers mainly includes: nitrogen, phosphorus, potassium, magnesium, boron, zinc, etc. and water, as well as toxic and harmful substances such as biurets in the production process of chemical fertilizers. Unqualified fertilizer products will cause serious harm to crops. For example: At present, most of the chemical fertilizers contain three main nutrients: nitrogen, phosphorus, and po...

AI Technical Summary

Problems solved by technology

For example: At present, most of the chemical fertilizers contain three main nutrients: nitrogen, phosphorus, and potassium. Among them, the urea content, that is, the nitrogen content, is the key quality index of fertilizers, and the impurities contained in it, such as biuret, when the content exceeds 1%, will It has adverse effects on the growth of crops, that is, "burning seedlings". Excessive moisture content will cause fertilizer compaction, which is not conducive to storage and transportation

At present, the quality analysis of chemical fertilizers mainly relies on traditional laboratory analysis methods. This method uses many reagents and involves steps such as weighing, dissolving, digesting, distillation, titrating, and calculating, which is time-consuming and laborious; There is a certain degree of danger and will have an impact on the environment

These limitations have affected the production, sales and rational use of chemical fertilizers to a certain extent

In addition, the production and application of chemical fertilizers in our country are heavy on nitrogen and light on phosphorus and potassium, which causes waste of resources, pollutes the environment, and endangers the health of humans, animals and plants. At the same time, the imbalance of nitrogen, phosphorus and potassium cannot meet the nutritional needs of crops for timely growth.
