Wi-Fi协议转换器在水文自动测报中的应用

水文自动测报站大多地处偏僻,测报系统工作条件恶劣,对现场仪器设备安装、检修、维护带来了一些困难,为此,开发了一种低功耗Wi-Fi协议转换系统。该系统包括智能数据采集器或者新型智能一体化传感器、协议转换器和无线硬件管理平台等设备,由于采用了合理的无线组网模式及工作模式策略,实现了较低的功耗。介绍了该协议转换器的系统整体架构、硬件设计和软件设计,最后分析总结了该方案相对有线配置与控制管理的优点。该终端功耗低、实时性高、灵活性强,具有良好的应用前景。

Application of a low-power Wi-Fi protocol converter in hydrological automatic forecasting system

Most of the hydrological automatic stations are in remote areas with harsh working conditions, which brings along a serious of difficulties to the installation, maintenance of the local instruments. Therefore, a low-power Wi-Fi protocol convert-er is developed, which consists of the intelligent data acquisition or new type of smart sensor integration, protocol converter, wire-less hardware management platform. The low power consumption is achieved by using reasonable wireless networking mode and working strategy. The overall system architecture, hardware design and software design of the converter are introduced and the ad-vantages of the converter are analyzed compared with the wired configuration and control-management. The terminal has the characteristics of low power consumption, good real-time performance and strong flexibility, which has good application pros-pects.
