管网智能终端产品中超低功耗设计与实现

Ultra-Low-Power Design and Implementation of the Intelligent Terminal Product in Pipe Network

功耗问题制约产品使用寿命日益突显,低功耗课题一直备受关注,如何严格控制好系统及各模块的静态功耗、动态功耗、峰值功耗等参数尤为重要。针对管网智能信息管理终端,从系统结构、电源拓扑结构、芯片选型、产品工作环境及诸多细节全局把握,使得系统休眠时静态工作电流低至9.0561uA,运行时总体工作电流低至22.670mA,电池使用寿命长逾三年,为智能终端产品超低功耗研究与设计提供有力支撑。

Because of the issue which power consumption constraints the product working life is growing increasingly, low power topics has been concerned extremely. How to control the system and module＇s static power, dynamic power, peak power and other parameters strictly is particularly important. With the intelligent information management terminal product in pipe network as the platform, considering the system structure, power topology, chip selection, product work environment and overall details, this paper gets an exciting test result： the system sleep current is as low as 9.0561uA, the work current is as low as 22.670mA, then the battery life can be over 3 years. All of this provides strong support in the ultra-low-power research and implementation for intelligent terminal product.
