基于语义互连模型的智能家居控制系统设计

Design of Smart Home Control System Based on Semantic Interconnection Model

常规的智能家居控制系统在未考虑到网络接入配置复杂性的情况下增加了大量指令,影响了系统的运行效果,故设计基于语义互连模型的智能家居控制系统。在对语义互连模型进行简要论述的基础上,采用STM32处理器与NodeMCU开发板设计系统硬件。系统软件设计方面,利用Z-stack协议栈对通信双方进行定义,调用OSAL函数完成家居控制任务;基于语义互连模型建立家居控制指令的上下文关联规则,生成智能家居互连控制数据点并从中获取数据,实现家居远程控制。测试结果表明:设计系统响应速度在0.1s以内,并发人数为600-1000人,连接稳定,可灵活扩展,且CPU占用率仅为26.54%,指令错误率仅为0.52%,功耗低至1.36W,整体安全性较高,说明设计系统的运行性能较为稳定,能够有效应用于实际中。

The conventional smart home control system increases a large number of instructions without considering the complexity of network accss configuration,which affects the opcration effect of the system.Therefore,a smart home control system based on semantic interconnection model is designed.Based on the brief discussion of the semantic interconncction model,the sys-tem hardware is designed by using STM32 processor and NodeMCU development board.In the aspect of system software design,Z-stack protocol stack was used to define the two sides of com-munication,and OSAL function was called to complete the home control task.Based on the se-mantic interconnection model,the context association rules of home control instructions are es-tablished to generate smart home interconnection control data points and obtain data from them to realize remote control of home.The test results show that:The response speed of the design system is less than 0.1s,the number of concurrent pcople is 600 to 1000,the conncction is sta-ble,and the connection is flexible,and the CPU occupation rate is only 26.54%,the instruction error rate is only 0.52%,the power consumption is as low as 1.36 W,and the overall security is high,which shows that the design system has stable operation performance and can be effective-ly applied to practice.
