為解決我國水位監測野外條件下長期無人看守的問題，研制開發了基于MSP430單片機的智能水位計。從其組成到各功能分別進行了詳細的介紹，該智能水位計不僅實現了水位數據的實時監測、記錄和定期采集等多種工作模式，而且提高了水位監測精度，實現了水位監測的智能化。
Abstract:
In order to solve the problems of long-term unmanned observation in the field water monitoring，an intelligence water-level meter based on MSP430 is developed composition and every function moduce of the water level meter was introduced in detail. It not only realizes water level data collection and storage， regularly gathering and so on， but also improves the water-level precision ， finally realizes the intelligence.
從系統硬件設計和軟件構成上，介紹一種以AT89C52單片機為核心,通過無線遙控方法實現對預設電話自動撥號報警的智能呼救系統。系統提供了患者在緊急情況下無法使用電話報警時的一種報警手段。由用戶預設的多組電話號碼作為語音報警對象,預錄可長達20 s的語音信號來說明患者所處地點及病情，并通知患者家人。
Abstract:
This paper introduces a intelligent alarming system which is realized by wireless remote control system.This system chiefly consists of AT89C51 the system can processor.User can input several groups of telephone number regarded as alarming objects,The system can record some information 20 seconds to tell the site of the patient.And notice the rokonok of the patient.
