從系統(tǒng)硬件設(shè)計和軟件構(gòu)成上，介紹一種以AT89C52單片機為核心,通過無線遙控方法實現(xiàn)對預(yù)設(shè)電話自動撥號報警的智能呼救系統(tǒng)。系統(tǒng)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(yù)設(shè)的多組電話號碼作為語音報警對象,預(yù)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.
介紹了電力操作電源與智能電池巡檢系統(tǒng)的特點，給出了一種基于超低功耗單片機MSP430 F149針對中小型變電站自動化運行的專用設(shè)備的基本設(shè)計原理及實現(xiàn)方法，最后給出了詳細硬件構(gòu)成和軟件實現(xiàn)。該系統(tǒng)能滿足中小型變電站安全、可靠、自動運行的要求，并通過與上位機的串行通信實現(xiàn)變電站的遠程管理和控制。
Abstract:
The characters of the intelligent battery data logging system of the electric operation power are introduced.The basic design principle and the implemented methods of the special equipment which only designed for the middle or small transformer substation based on MSP430F149 are prescribed. Finally, the hardware block diagram and the software flow chart are also given. The function that the system finally needs to realize can basically meet with the middle or small transformer substation’s satisfy, reliably,and automatic running.And it can also realize the transformer substation long-distance management and control by serial communicating with the host computer.
出了一種利用ATmega8單片機對ISD2500系列語音芯片進行控制的智能語音系統(tǒng)，此系統(tǒng)使用靈活，易于功能升級，具有良好的應(yīng)用前景。提供了硬件連接電路和關(guān)鍵源程序。
Abstract:
An intelligent voice system using ISD2500 series voice chips based on ATmega8 MCU is described.This system is flexible and easy to upgrade for users,and it has pretty good using foreground. The circuit diagram and the key program are also provided.
