基于TSCH模式的工业无线系统级芯片设计
|
摘要
当前商业无线芯片只能实现工业无线网络标准的通信功能,时隙调度和同步等功能必须依靠软件通过定时中断的方式实现,增加了开发难度,限制了WIA-PA等工业无线协议的推广和普及。针对该问题,设计一款支持TSCH模式物理层协议面向工业无线网络的系统级工业无线芯片WIASoC2400。该芯片以IEEE802.15.4e协议的TSCH模式为基础,基于ARM Cortex-M3内核,集成2.4 GHz WIA-PA无线通信模块,同时包含符合IEEE802.15.4-2006协议CCM~*模式安全规范的AES-128加/解密安全模块,可保证数据传输的安全性。仿真结果表明,WIASoC2400能够满足TSCH模式下通信的时隙同步精度和跳频要求,具有定时精确、处理速度快、实现简单等优点。
At present,commercial wireless chips can only realize the communication function of the industrial wireless network standard,while leaving the functions like the slot scheduling and synchronization to rely on timing interrupt by the software.Therefore,previous solutions increase the difficulty of development and restrict the popularization of industrial wireless protocols such as WIA-PA.To solve the above problems,in this paper,a system level industrial wireless chip for industrial wireless network is designed,named WIASoC2400,which supports the physical layer protocol of the TSCH mode.It bases on the TSCH mode of the IEEE802.15.4 e protocol and the ARM Cortex-M3 kernel,and integrates 2.4 GHz WIA-PA wireless communication module.In addition,in order to ensure the security of data transmission,it includes AES-128 encryption and decryption module,which is consistent with the security specification of IEEE802.15.4-2006 protocol CCM*mode.Simulation results demonstrate that WIASoC2400 can satisfy the requirements of time slot synchronization accuracy and frequency hopping in TSCH mode,and has the advantages of precise timing,fast processing and simple implementation.
