奶牛精量饲喂系统研究

Research on Precise Feeding System of Dairy Cattle

精量饲喂系统的核心技术是奶牛个体识别技术。系统采用了非接触式的无线射频识别(RFID)技术,奶牛佩带符合ISO11785标准的电子标签。采食开始前,系统核对奶牛信息后按照饲喂要求进行自动投料。系统各测量数据将通过以ZigBee为核心建立起来的无线网络传输到主控计算机,同时主控计算机将奶牛饲喂规则的相关控制指令也通过无线网络传送到饲喂装置,控制饲喂装置工作。系统预留相关扩展接口方便后续升级使用。

The precise feeding system and relevant key technologies,including RFID,network based on ZigBee,measuring technique etc,are discussed.The precise feeding system is composed of central computer,precise feeding devices and wireless network used to build up the distribute system.The core of the precise feeding device for dairy cattle is identification of individual dairy cattle.The RFID,a non-contact identification technology,is integrated in the system.The electrical ring made according to ISO11785 international standard is worn by individual dairy cattle to identify each dairy cattle.The information of the cattle is checked by the system and then certain amount of forage is given.On the course of intake,all feeding data are collected by the system such as the unique electrical code,actual intake of forage,feeding time,feeding velocity,etc.The feeding formula is given by the program running on central computer connected to precise feeding device by ZigBee network.Some interfaces of system are reserved for the extending function so that it will be easy to update system.The precise feeding system can provide a solution of high efficiency and high benefit for dairy farming.
