物联网差异体系结构下的设备调度平台设计与实现

Design and implementation of equipment scheduling platform under Internet of Things difference architecture

物联网差异体系结构下的设备操作性能和通信协议等方面存在异构性,网络资源受限,使得传统物联网下设备调度方法的调度质量降低,存在较高的滞后性。设计物联网网关系统架构,实现物联网差异体系结构下设备的无缝连接和即插即用,增强设备调度质量。网关通过输入端融合模式的无线通信方法,实现不同类型设备的无缝连接。设计网关的主管理模块、缓存管理模块以及调度模块控制网关的调度,确保在资源有限的物联网差异体系结构中,对设备进行合理调度管理。实验结果表明,当调度平台的网关达到4 000并发数时,平台进入稳定阶段后各设备平均调度等待时间为4.5 s,平台可保持稳定运行状态。

There is isomerism in the aspects of equipment operation performance and communication protocol under the IOT difference architecture, so the network resources are limited, which makes the scheduling quality of traditional equipment scheduling method reduced in the Internet of Things, and high hysteretic nature occurred. The architecture of IOT gateway sys- tem was designed, and the seamless connection and plug and play of equipments under the IOT difference architecture were realized, which enhanced the equipment scheduling quality. The seamless connection of different types of equipments was realized by the wireless communication method of gateway with input end fusion mode. The main management module, cache management module and scheduling module were designed to control the gateway scheduling, and ensure the reasonable scheduling management of equipments in the IOT difference architecture with limited resources. The experimental results show that the average scheduling waiting time of each equipment is 4.5 s and the platform can keep the stable operation condition when the gateway of the scheduling platform reaches up to 4 000 concurrency, and the platform enters into the stable stage.
