Studies On The Testing System For Dairy Cow Accurate Precision-feeding Intake

With the development of national economy, people's living standards have been improved, and the animal husbandry has been greatly developed into a new industry where the leading industry. Dairy industry is an important part of animal husbandry which occupies an important status in the national economy and social development. But with the rapid development of China's dairy industry, how to improve milk production and cow milk quality, and efficiency is a major issue. For the sustained and healthy development of China's dairy industry, the scale of operation as the carrier, promoting the standardization of dairy farming, intensive and scientific construction, production management from the traditional to the modern management pattern and increasing scientific and technological content is crucial.Ruminant feeding intake is required for animal health and production which is based on the quantification of nutrients. Only improving the dairy cow feeding intake equitably and continuously, do dairy cow have access to more comprehensive nutrients before they can achieve the desired milk production, and to improve industry revenue. However, the poor timeliness of data errors would exist which are relied on manual collection that would leads the management to a great degree of difficulty. Therefore, in order to make the management of dairy dairy cow more scientific, standardized and fast, the use of computer technology is imminent to promote mechanized feeding.This paper analyzes the dairy cow feed the development status of technology and determined the device's technical requirements. According to the analysis of the design process, the overall scheme of feeding device has determined. The device is mainly composed by feeding body weight bodies and discharging institutions. Based on the virtual instrument and its software development platform, the single chip wireless data communication is achieved with the Lab view PC and the AVR ATmega32, respectively, the wireless transceiver chip was designed based on the wireless communication module NRF24E1 load cell-based wireless data acquisition module. The wireless data acquisition module of the system improves the intake of traditional measurement methods and uses the weighing sensor technology to quickly and easily collect the data. Through the chip selection and chip peripheral circuits, it improved and optimized hardware improvements, and designed an effective communication protocol to improve the accuracy of the collection of individual dairy cow, and to prevent the transmission of data signals and have removed the distortion error signals. Between simple upper and lower computer serial communication, the Labview graphical programming makes the system high degree, clear structure, easy commissioning and reliable operation.Experimental results show that the development of the dairy project information collection system is used friendly. The feature is more comprehensive, and the feeding dairy cow data collection is achieve at the same time, its operation is simple and could meet the basic needs of data collection for dairy farms. Low system cost, low- power consumption, high reliability and widely used indicates a good prospect.
