The Key Technology Of Digital Cow Management

This paper discusses the cows digital management technology research, the cow is the key technology of digital management information through a variety of advanced electronic equipment acquisition cows, then through the computer software analysis, it is concluded that a variety of data related to the cow, cow breeding personnel provide various feeding advice. The system is mainly composed of cow information collection equipment and the cows of information analysis software. Cow information collection equipment is the key technology to realize the cow digital management, including milk composition analyzer, dairy cattle ruminant online monitoring device, cow activity monitoring device and the cow positioning device four parts, the acquisition equipment record every cow all kinds of data, and then through the analysis of the data link to run the cow information analysis software of computer processing.Milk composition analyzer is an online real-time, fast, low-cost on-line milk composition analysis instrument, is one of the key technologies to realize modernization of milk production, to improve the quality of the milk has a vital role. Analyzer can real-time measuring the content of protein, fat, lactose, milk and the measured data real-time transmission to the computer system, by a dedicated computer software to judge the quality of raw milk, and controls the solenoid valve will different quality of raw milk to different containers, so as to realize the function of the separation of raw milk. The instrument can also be used to test each cow health, simplify the cow breeding management.Cows ruminant monitoring and cows activity monitoring is mainly used to detect the state of health of dairy cows. Cows ruminant rhythm and time has close relationship with the cow health, through the cud signal acquisition and analysis, can be more accurate detection of cows physiological activities, and timely find ruminant animal health problems. By monitoring the activity of cows, which can be found in heat cow, in order to achieve the purpose of breeding date.Cows positioning device used to zap the cows with identification equipment to locate, and display on the map, you can always find a rut or sick cows, can record the trajectories of cows at the same time, as the basis of the cow activity monitoring.This paper has the following innovative points:(1) Online milk composition analyzer used advanced LED light source technology, different from the traditional spectrum analysis instrument, the use of low cost LED to replace the expensive optical spectral components, greatly reduces the production cost and power consumption, and reduce the volume of the instrument, sped up the measurement speed, can do a milk every location configuration.(2) Milk composition analyzer can measure online, online measurement process doesn’t contaminate the sample, can achieve the single cow milk composition detection and separation of different quality milk two traditional milk composition analyzer cannot function.(3) Milk composition analyzer used the constant temperature technology, constant temperature of light source parts processing, can effectively inhibit the environment temperature change influence on the measured results.(4) Online milk composition analyzer used the 300-1000 nm band, different from the research more near-infrared (0.8-2.5 (including m), infrared (2.5-25 (including m) in milk composition analysis method, has the originality.(5) Rumination information acquisition device adopts the piezoelectric sensors, relative to the electrets microphone greatly reduces the noise, improve the reliability of the whole.(6) Rumination information collection device USES low power circuit design, greatly extend the battery life, don’t need to replace the battery service life, it is more convenient to use.(7) Rumination information acquisition device adopts the design, waterproof, dustproof, collision installed in cows neck is not easy to damage, improve the reliability, and greatly extend the service life.(8) cow active monitoring device of an innovative way of using sensor and analysis algorithm, can be installed on the neck of the cow, so you can active the cow monitoring device and regurgitate information collection device together, it is more convenient to install and use.(9) Positioning technology was applied to the cow, and on the satellite map shows the location of the cow, all belong to the first at home and abroad.(10) Based on ARM embedded system design of host machine, reducing the production costs relative to the upper machine PC platform.
