摘　　要：由于水情测报终端应用环境恶劣,保证水情测报终端的稳定性和低功耗显得尤为重要,提出了基于ARM7LPC2119在水情测报上输出单元的设计与实现,把嵌入式技术运用到水情测报控制中,设计了一个最小系统。在有人或无人的情况下,通过PC机或者上位机发送用户需要的指令,远程控制电机工作,从而控制闸门的升降,达到了水资源调度和控制的目的。详细叙述了整个系统的功能及其构成模块,给出了电源转换模块、中心模块、通信模块、外围驱动模块的硬件接口电路图。本系统在都江堰下属闸门经过实际运行表明设计是准确可靠的,实现了在无人的恶劣环境下的长时间低功耗稳定工作,比以往的设计更省电,更经济适用,在市场上有广泛的应用前景。Due to the poor application environment, for the hydrological unit output terminal, to ensure the stability and low power consumption is particularly important. This paper presents the hydrological forecast output terminal design and implementation based on ARM7 LPC2119. By the embedded technology applied to the hydrological forecast,a minimum system is designed. In the case of someone or no one, sending the instructions of user needs through the PC or host computer to control the remote motor,in order to control the rise and fall of the gate. A detailed description of the functions of the whole system and its modules are given. The paper gives some hardware interface circuits of the power conversion module, the center module ,communications module ,external drive module. After the actual operation on the gate in the dujiangyan,it shows that the design is accurate and reliable. In the absence of people,it achieves the long time and low-power stable work. The design is more energy-efficient than ever before,is affordable. It has a broad application prospect in the market.
