Abstract无线芯片是工业物联网协议实现的硬件基础,当前商业物联网无线芯片只能实现物联网协议的通信功能,而时隙调度和同步等功能却依靠软件通过定时中断的方式实现,因此增加了开发难度、限制了WIA-PA等工业无线协议的推广和普及。针对上述问题,设计了一款支持TSCH模式物理层协议的面向物联网的系统级工业无线芯片WIASoC2400。WIASoC2400以IEEE802.15.4e协议的TSCH模式为基础,基于ARM Cortex-M3内核,并集成2.4GHz WIA-PA无线通信模块。此外,针对工业无线网络中数据传输的安全性要求,设计了符合IEEE802.15.4-2006协议CCM*模式安全规范的AES-128加解密安全模块。通过对芯片样片进行大量的仿真实验,测试结果表明,WIASoC2400能够满足TSCH模式下通信的时隙同步精度和跳频要求,定时更精确、处理速度更快、实现更简单,能够满足工业无线协议的实时性、稳定性和安全性需求。
Other AbstractWireless chip is the hardware basis of the implementation of the industrial Internet of Things (IoT) protocol. Current commercial IoT wireless chips can only realize function of communication in IoT protocol. However, they implement functions of time-slot scheduling and synchronization by means of software time-interrupt, which would increase the difficulty of development and limit the popularization of industrial wireless protocols such as WIA-PA. To solve problems mentioned above, in this paper, an industrial wireless network protocol System-on-chip (SoC) for IoT, named WIASoC2400, is designed and implemented. Basing on the Time Slotted Channel Hopping (TSCH) mode in the IEEE802.15.4e standard, WIASoC2400 combines the ARM Cortex-M3 MCU and a 2.4GHz radio module. Besides, in order to meet the security requirements of data transmission in industrial wireless networks, a hardware security accelerator based on the AES-CCM* mode in IEEE802.15.4-2006 standard is designed. A series of simulations and experiments have been carried out on the SoC, and the results demonstrate that the SoC can satisfy requirements of synchronization accuracy and channel hopping in the TSCH mode, and work with more precise timing, faster processing and easier coding. So the WIASoC2400 can satisfy the requirements of real time, reliability and security for the industrial wireless network standard.
