Radio Frequency Identification (RFID) is a non-contact automatic identification technology. Its basic principle is to realize the automatic identification of objects by using the transmission characteristics of radio frequency signals and spatial coupling (electrical coupling or electromagnetic coupling). The RFID system is generally composed of two parts, namely an electronic tag (transponder Tag) and a reader (reader Reader). In the practical application of RFID, the electronic tag is attached to or embedded in the surface of the identified object. When the identified object with the electronic tag passes the readable range of the reader, the reader automatically places the electron in a contactless manner. The agreement identification information of the tag is taken out, thereby realizing the function of automatically recognizing the object or automatically collecting the object mark information.
1 RFID application in modern dairy farms In the dairy farms with large breeding scale, high breeding level and high individual production capacity, the conventional manual marking and the naked eye recognition of dairy cows are distinguished, the work is difficult, the resolution efficiency is low, and the error is The high rate makes it difficult to accurately and comprehensively grasp the production level and individual status of the dairy cow group, which cannot meet the requirements of modern cattle farm management. As a new non-contact rapid automatic identification technology, RFID is being more and more widely used in modern, large-scale farming industry towels. The technology can be applied in many aspects of dairy cattle production, including automatic ration of cattle rations, statistical analysis of milk production, individual identification of cows, prevention and control of disease surveillance, product quality control and animal traceability tracking.
1.1 Individual accurate electronic files are distinguished from traditional dairy cards and paper archives. The electronic logo designed for dairy cows stores various basic information about cows and has a 16-digit number strictly in accordance with International Organization for Standardization (ISO) coding standards. When the cow is born, the electronic logo is fixed on the animal body, and the electronic logo is used once, uniformly numbered, and the number is unique. From then on, the electronic logo will accompany its life, thus achieving the world's only one, achieving 100 animals. Electronic signs are usually designed and packaged in a variety of forms such as injection implants, ear hooks, rumen and ankle rings. In practical applications, through the supporting software management program, various dynamic data can also be stored correspondingly and updated in real time to form a dynamic database of individual cows.
1.2 Real-time monitoring and data acquisition application Radio frequency technology can monitor the status of the cows in real time and collect various data information recorded by electronic identification in a timely and accurate manner. The wireless radio frequency system can dynamically identify and record the data such as the weight, feed intake and exercise volume of the cattle, and combine the other sensors of each breeding module to record and record the bovine body condition, the temperature and humidity of the cattle farm, and dynamically monitor the condition of the cattle at the computer terminal. Monitoring, once the data collected by the system exceeds the health warning threshold set in the computer, the management system can automatically identify it and provide timely feedback to judge the physiological state of the cattle, adjust the feed structure and supply quantity, and formulate the treatment plan. Reference data.
1.3 Equipped with modules for auxiliary feeding and management The radio frequency system can be used as an information platform to carry a number of auxiliary feeding modules. The exercise pedometer on the electronic sign records the amount of exercise of the cow, and combines the accumulated data and standard parameters in the database to determine the condition of the cow's sebow and the identification of the estrus. The precision feeding module is used to equip the cows at different growth stages and different milk yields on the same day. In the computer system, comprehensive training 'calculates the best recharge amount of the concentrate, and feeds back to the precision feeding system for precise feeding to achieve the purpose of different feeding of different cows. The milk analysis and detection module can be used for each cow. Milk production, milk production efficiency, milk composition and other data for monitoring and analysis and record comparison, timely grasp the cow's breast health status, whether the feed formula is scientifically perfect; with the milking station monitoring module, you can record every shift into the milking parlour The milking time of each cow, the state of milking, the state of equipment, the manager can find out the standardization and proficiency of the milking worker during the milking process, and the milking person can also find it during the milking process. The problem is fed back to the manager with a pre-set digital language input system.
