【摘要】：为了加强政府对木材供应链的监管,帮助企业提高木制品国际市场竞争力,基于AT89C2051单片机设计了木材供应链管理手持机,使用了AT24C16芯片的IC卡作为供应链追踪卡,手持机能够向IC卡写入供应链日志及GPS时间、经纬度,帮助企业实现原材料的溯源,加强木制品品质的管控,并且对林业执法过程进行有效的监督。同时设计了基于MD5加密的改良算法,使篡改和伪造追踪卡具有较大的技术难度。该项设计能够阻断非法木材进入供应链,保护森林资源,实现林业经济可持续增长。
[Abstract]:In order to strengthen the government's supervision of wood supply chain and help enterprises to improve the competitiveness of international market of wood products, a wood supply chain management handset based on AT89C2051 microcontroller is designed, and the IC card of AT24C16 chip is used as the supply chain tracking card. The handset can write the supply chain log and GPS time, latitude and longitude to IC card, help enterprises to trace raw materials, strengthen the quality control of wood products, and supervise the forestry law enforcement process effectively. At the same time, an improved algorithm based on MD5 encryption is designed, which makes tampering and forgery tracking card more difficult. This design can prevent illegal timber from entering supply chain, protect forest resources and realize sustainable growth of forestry economy.
