【摘要】 近年来,食品安全案件屡有发生,亟需采用透明、安全、可信的食品安全溯源系统。然而现有的溯源系统高额的视频监测储存和传输费用,限制了溯源平台的推广。设计基于RFID具备联动功能的智能感知摄像机,采用自修复机制改进基于RFID的LANDMARC定位算法,精准定位每一只牲畜的活动区域;利用联动摄像头定量采集牲畜活动信息,建立牲畜活动信息;通过GPRS将采集的照片上传到服务器,极大降低视频存储和传输成本。同时将摄像头的功耗降到最低,使其能在野外用太阳能板为系统供电。用户可以通过扫描二维码查询牲畜档案信息,极大降低绿色健康畜产品溯源成本,推动溯源系统的广泛应用。更多还原

【Abstract】 In recent years,food security cases have occurred repeatedly.It is urgent to adopt a transparent,safe and credible food security traceability system.However,the high cost of video monitoring storage and transmission in the traceability system limits the promotion of traceability platform.We designed an intelligent sensing camera with linkage function based on RFID,and used self-repair mechanism to improve the RFID-based LANDMARC positioning algorithm to accurately locate the active area of each animal.We used the linkage camera to collect the information of livestock activities quantitatively and establish the information of livestock activities.The collected photos were uploaded to the server through GPRS,which greatly reduced the cost of video storage and transmission.And we minimized the power consumption of the camera,so that it could use solar panels to power the system in the field.Users can search livestock archives information by scanning QR codes,which greatly reduces the traceability cost of green and healthy livestock products and promotes the wide application of traceability system.更多还原
