摘　　要：研究并比较了异构数据问题的解决方案,提出了农场异构设备物联网混合分布式解决方案.建立了农场异构设备物联网模型,设置了农场应用场景,优化并改进了封锁和集中式FOCC控制机制,解决了对设备并发管理和控制时所带来的一致性问题.实验结果表明,封锁和集中式FOCC机制是有效的,但在一定情况下会增加系统时间开销.This paper studies and compares the solutions to heterogeneous data problems, puts forward hybrid distributed solutions to farms＂ heterogeneous device networking, sets up a farm heterogeneous devices networking model, structures a farm application scenario, improves and optimizes the closed and centralized FOCC control mechanisms, and solves the consistency problem caused by concurrent management and control of equipment. Experimental results show that the closed and centralized FOCC system is effective, but in some cases it will increase the time overhead of the system.

关 键 词：物联网 异构设备 控制机制 封锁 集中式FOCC
