摘要: 随着物联网技术发展，智能家居、工业互联等场景对无线通信提出低延迟、高可靠、多设备连接和低功耗的要求。星闪(SLE)作为我国自主研发的短距无线技术，为物联网碎片化连接提供了解决方案。本文基于海思Hi3863芯片设计多模星闪网关系统，实现星闪与Wi-Fi异构网络的互联，构建边缘数据枢纽。本文首先分析了多模网关的需求，提出了以Hi3863为主控、集成了星闪与Wi-Fi通信模组的硬件架构。系统采用分层软件设计，底层基于LiteOS操作系统抽象层进行任务调度与资源管理；中间层分别实现了星闪协议栈的设备发现、连接管理、数据传输功能，以及基于LWIP的Wi-Fi TCP/IP通信功能；应用层核心设计了一个智能数据转发引擎，通过解析数据包中的网络与设备标识，实现星闪网络与Wi-Fi网络间数据的无缝转换与可靠转发。测试结果表明，本系统能够稳定维护多个星闪设备与Wi-Fi客户端的并发连接，成功实现了跨异构网络的数据透传，有效验证了基于Hi3863构建低成本、高性能多模星闪网关系统的可行性。

Abstract: With the advancement of IoT technology, applications such as smart homes and industrial interconnection require wireless communications to meet demands for low latency, high reliability, multi-device connectivity, and low power consumption. As a short-range wireless technology independently developed in China, SparkLink provides an effective solution to fragmented connectivity in IoT. This paper designs a multi-mode SparkLink gateway system based on HiSilicon’s Hi3863 chip, enabling interconnection between SparkLink and Wi-Fi heterogeneous networks to establish an edge data hub. The study begins by analyzing the requirements of multi-mode gateways and proposes a hardware architecture with Hi3863 as the main controller, integrating both SparkLink and Wi-Fi communication modules. The system adopts a layered software design: the underlying layer utilizes the LiteOS operating system abstraction layer for task scheduling and resource management; the middle layer implements SparkLink protocol stack functions including device discovery, connection management, and data transmission, as well as Wi-Fi TCP/IP communication based on LWIP; the core application layer features an intelligent data forwarding engine that enables seamless and reliable data transmission between SparkLink and Wi-Fi networks by parsing network and device identifiers in data packets. Test results demonstrate that the system can stably maintain concurrent connections with multiple SparkLink devices and Wi-Fi clients, successfully achieving cross-heterogeneous-network data transparent transmission. This effectively validates the feasibility of constructing a low-cost, high-performance multi-mode SparkLink gateway system based on Hi3863.
