電話網路全方位監控系統

摘要或動機

In this paper, we use telephone network to remote-control household appliances and monitor security system through the implementation of software and hardware. The purpose of developing this system is to build up a system that makes everyone take advantage of the telephones through pay phone network everywhere as and when he needs to set up the household appliances, meanwhile two-ways system of monitoring household security. In addition, due to the advances of communication technology and the remarkable boom of those products, the popularity of cell phones for local people is developing tremendously. We can link the portable cell phones up to the household appliances and monitoring household security through the offer network of communication companies. This system adopts public telephone network via multiple frequency to receive KT31 70 IC which is connected to EM78P45 i p Chip. And then the Chip is connected to the driving external circuit in order to control electric appliances, sensors on doors and windows. The utilization of LEPROM (93C66) memory to set up telephone and mobile phones number equips the telephone network with two-ways system of remote-controlling electric appliances and monitoring household security. In the part of controlling electric appliances, a monitor is used to display the status of electric appliances, to control the appliance switches and to set up the timer. In the part of monitoring household security, we use the system to receive the instant images of the house and to report on the closing or opening of doors and windows. The system will be informed on any occurrence of abnormalities. The memory of the system can record and update new data at any time and is able to set up twenty sets of telephone and mobile phone numbers. Besides, the system adopts identification codes to avoid malfunctioning and thus upgrade system reliability.本文旨在應用電話網路作遠端遙控家用電器及防盜保全歟控系統軟硬體之規劃與設計 。本系統研製的目的，是希望建立一套系統，讓每個人不管身置何處，都能利用電話透過公眾電話網路，輕易地控制家中的電器設備及進行環境設定，以達到控制家電及防盜保全之雙向監控系統。此外，由於通訊的進步與通訊產品的熱賣，使國月雍有手機的普遍性相當高，若能透過隨身攜帶的手機，經由通訊業者所提供的網路通訊管道，連結到家庭自動化與防盜保全系統亦可達到進行遠端遙控的目的，彌補出門在外無法使用室內電話的空檔。本系統利用公眾電話網路經複頻接收 IC ( KT3 170 ）連接至單晶片（ EM78P45 IP ) ，透過單晶片驅動外部電路與家中電器及門窗的監視感測器連接，再利用 EEPROM ( 93C66 ）記憶體設定電話及手機號碼，藉由電話網路傳輸，以達到控制家電及防盜保全之雙向監控系統。在家電控制部份，採用顯示器可隨時瞭解家電使用狀況及控制其開啟或關閉，且可設定使用時問。在防盜保全部份，可隨時監控家中門窗，若有異狀可即時通告。記憶體可隨時記錄或更新資料，並可設定二十組電話及手機號碼。此外，本系統採用確認碼設定，可防止產生誤動作，系統可靠性高。
