電梯自動語音提示系統(tǒng) 院 系:信息科學與工程學院 專 業(yè) 班:電子科學與技術(shù) 1102 班 姓 名: 學 號: 指導教師: 20xx 年 5 月 電梯自動語音提示系統(tǒng) The Elevator Automatic Voice Prompt System I 摘 要 電梯自動語音提示系統(tǒng)是現(xiàn)代所有電梯的大腦和神經(jīng)中樞。自電梯問世以來,電梯不斷高端化美觀化只能化,老式單純的升降電梯已經(jīng)成為了歷史,現(xiàn)代建筑中無論在什么場合安裝的電梯都是智能化、自動化的,它們大多數(shù)都是由單片機或 者嵌入式系統(tǒng)控制的。 本設計首先確定的目標是實現(xiàn)對八層電梯語音提示系統(tǒng)模型的設計,主要通過單片機 (89C52)、八個分別代表樓層的按鍵、 LED 數(shù)碼管顯示屏、 VS1003 語音模塊四個部分協(xié)調(diào)工作,實現(xiàn)電梯的自動語音提示功能。本設計的電梯自動語音提示系統(tǒng)以單片機( AT89C52)作為核心,然后通過矩陣鍵盤按鍵是否按下而引起電平高低的變化,然后將該電平變化的信號送入到單片機中,單片機通過相應樓層按鍵按下與否的檢測結(jié)果和上下行檢測的結(jié)果做出相應的處理和判斷,然后將該信號發(fā)送到語音模塊,最后語音模塊播報樓層變化和最終 到達的樓層以及電梯的上下行狀態(tài)。軟件編程語言選用的是 C 語言,利用查詢的方式來檢測電梯用戶按下的按鍵信息。本設計是模擬一個簡單的電梯自動語音提示系統(tǒng),將按鍵代表樓層,當相應樓層按鍵按下是引起電平高低的變化,然后將相應的電平信號傳入到單片機中,然后單片機計數(shù)來確定樓層數(shù),最后將信號輸出到 LED 顯示模塊和語音播報模塊分別進行樓層顯示和語音播報。 關(guān)鍵詞: 自動語音提示 單片機 語音模塊 上下行狀態(tài) II Abstract The elevator automatic voice prompt system is the modern all the brain and the nerve center of the lift. In addition to those who stay in order to protect the historical old elevator,no matter in what occasion of installation of the elevators are automatic, they are basically controlled by single chip microputer, advanced elevator also used the embedded system. First determine the design goal is to achieve the eight design of elevator voice prompt system model, through the single chip microputer, eight floors respectively from the buttons, LED digital tube display, VS1003 voice module four parts coordination work, realize the automatic voice prompt function . Hardware part is mainly posed of single chip microputer module, elevator button circuit simulation testing module,floor broadcast voice module, elevator has LED display module and floor broadcast voice module four parts. The system USES singlechip puter (AT89C52) as the core, using the keys pressed or not caused by the change of the level, as users request information sent to the singlechip microputer, singlechip microputer according to the detected signal control floor speech broadcast and up and down the floor. Software part using C language, the use of a query to the detection of the key information, the user requests the operation of the elevator to the floor, simulate keystrokes level change, sent to the singlechip microputer count to determine the floor number, and sent to the display module and speech module for display and speech broadcast respectively. Key words: automatic vioce prompt voice module single chip microputer voice module the status of up and down III 目 錄 摘 要 I Abstract II 緒論 III 1 課題研究的背景 2 電梯自動語音提示系統(tǒng)研究的背景與意義 2 電梯自動語音提示系統(tǒng)的發(fā)展現(xiàn)狀 2 電梯自動語音提示系統(tǒng)終端節(jié)點設計的主要內(nèi)容 2 2 系統(tǒng) 總體設計 4 系統(tǒng)構(gòu)成框圖 4 總體設計思路 5 3 系統(tǒng)硬件結(jié)構(gòu)設計 6 AT89C52
