一种低功耗多路并行无线网关设计及应用

DESIGN AND APPLICATION OF LOW POWER MULTIPLEX PARALLEL WIRELESS GATEWAY

设计并实现一种兼容多种无线通信协议的无线网关,它通过Wi-Fi模式接入互联网,通过顶层POST通信协议的设计实现以适配ZigBee、BLE等流行的短距离无线通信终端设备。软件基于开源的FreeRTOS实时操作系统开发,利用混合式调度实现了基于软硬件协同的并行通信,提高了无线网关的吞吐量,并将低功耗模式嵌入到任务调度中降低了无线网关的整机功耗。将无线网关应用于实际的ESLS系统,测试结果表明无线网关性能稳定,灵活性和可扩展性强。

A wireless gateway is designed and realized,which can be compatible with multiple wireless communication protocols.It accessed the Internet through Wi-Fi mode,and adapted to the popular short-distance wireless communication terminal equipment such as ZigBee and BLE with the top-level POST communication protocol.The software was developed using the open source FreeRTOS real-time operating system,it realized the parallel communication based on software and hardware cooperation using hybrid dispatch method,which improved the throughput of the wireless gateway,and reduced the wireless gateway power assumption by embedding low power mode into task dispatching.The wireless gateway was applied to the real ESLS system.The test results reveal the stable performance,strong flexibility and scalability of the wireless gateway.
