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.
