散养模式下猪只个体标识及溯源体系的建立

Identification of swine individuals and construction of traceability system under free-range pig-rearing system

为了猪肉安全生产的监管和满足食品消费者的知情权,保障猪肉食品的公共安全,论文采用标识技术、PDA移动智能识读技术、GPRS技术和Internet等技术,结合中国"畜禽标识及养殖档案管理办法",提出了猪只散养模式下养殖过程信息的采集技术方案,设计了散养模式下养殖过程信息的元数据结构及相应的mobile数据表,开发了猪只移动养殖环节数据采集记录与传输的嵌入式系统,与面向政府监管和消费者查询的公共网络平台实现了移动互联。所开发的移动系统能够实现猪只耳标的移动识别、包括饲料、兽药使用和违禁药品监测等各种事件的移动记录,及时向溯源数据库移动系统提交出栏猪只的养殖数据,同样可远程维护散养猪只的养殖档案数据,最终实现散养模式下从生产源头到消费终端的跟踪和溯源。该移动数据采集系统,解决了中国养猪业主体模式——农户散养模式下猪只养殖电子档案建立的难题,并经在天津猪肉质量溯源体系中的实际应用证明是可行的,个别技术瓶颈随通讯技术的发展将得到解决,其全面实施将为保证中国农户养殖模式下生猪及其产品溯源体系与制度的建设提供技术支撑。

In order to meet the requirements of government supervision of pork production safety as well as consumer s right to know what they buy and to protect the public safety of pork food,animal identification,intelligent PDA mobile inquiring and reading,GPRS,internet and other information technologies were adopted,and a data collection method was uploaded to set up pigs farming files under free-range pig-rearing system.Related metadata structures and its mobile database was designed,and a mobile PDA embedded sys...
