Research On The Environment Measure And Control System In Livestock Breeding Field & The Data Processing

Intelligentized measure and control technology in livestock breeding field is a very important direction for developmental stockbreeding in 21st Century. It will promote the change form extensive and low effective stockbreeding to knowledge, technologybased and aggiornamento, highly effective in pasture husbandry. In developed country, it is considered as a revolution of livestock production management at the threshold of the new millennium, it is also researched and carried out by many national or overseas experts and scholars. The key of measure and control technology in livestock breeding field is implemented of variable management measures based on the spatial and temporal variability of the environment and status of livestocks. According to the condition of the project, this paper mainly studied the technology of field information acquisition and annals data handling based on sensor array, virtual instrument, industry personal computer. The main contents of this dissertation include:Based on the analysis of the measure principle of dust and measure method of maleficent gases in livestock breeding field, in allusion to the contaminate of dust and maleficent gas in livestock breeding field, the measure and control system is designed in this paper. According to the characteristics of field information acquisition, we studied some field sampling methods. Different sampling methods should be used according to the testing requirement, we advanced dynamic information sampling. Using module design method, the soft of field measure and control system is also exploited based on the National Instruments (NI) Lab VIEW 7.1 Express. Field signal acquisition is simulated and tested, too.The aim of data processing is precise figured out maleficence gases emission and analysed the reason which maleficence gases come into being,taked measure cut down these maleficence gases emission.Annals datum which is from database of livestock breeding field is analytical base. According to annals datum, producer and governor can adjust and control in livestock breeding field .Before annals datum are more analyzed and handled, spoiled datum in annals datum are usually corrected and rectified. The main thought of data processing is: Firstly, spoiled datum are ascertained in certain data curve. Secondly, spoiled datum are located in the data curve. Last but not least, spoiled datum are removed from and the data curve are amended based on the criterion curve.According to peculiarity of Self-Organizing Feature Map (SOM) Neural Network and Radial-Basis Function (RBF) Neural Network, by analyzing the effect of SOM network clustering and RBF network...
