中文摘要 | 本研究提出應用電話網路作遠端遙控家用電器之硬體規劃與設計。本系統利用公眾電話網路輸入各 種不同按鍵聲音,經過 DTMF 解碼器積體電路MT8870 解碼,解碼成數位信號,再利用數位信號啟動電器 的電源開關,或是電器的遙控器來控制電器。所提出的電路具有以下之優點:採用電話網路作通訊媒介, 收訊佳,效果好,涵蓋範圍廣。並具有成本低,有利於電路的積體化。最後,使用數位電路設計來驗證 電路之結果與理論可行性。 |
英文摘要 | In this paper, we uses telephone network to remote-control household appliances through the implementation of hardware. This system adopts public telephone network to input different key-tone and using DTMF decoding integrated circuit MT8870 to decode to digital signal. And then the circuit is connected to the driving external circuit in order to control relay or remote controller. The proposed circuit has following merits: adopting PSTN as transport medium to minimize defects, outstanding reception, extensive coverage, and low cost. All of which aids in circuit integration. At last, digital circuit design is implemented to corroborate circuit loopback test and design pattern validity. |
