【正文】 是四片十進制可逆計數(shù)器74LS192芯片，分別設(shè)計為十進制和六進制電路，用于完成時間的定時、計時功能。電機控制電路采用了38譯碼器74LS138和與非門電路的組合，實現(xiàn)電機正反暫停狀態(tài)。關(guān)鍵詞 ：洗衣機控制 ；數(shù)字電子控制；定時器Abstracts：The design is based on the simple digital circuit timer of washing machine. The washing machine is to be positive negative and suspension by preset time, and expressed in different light to suspend three washing state. After the time run over, will automatically alarm, beeping. At the same time, with two digital tubes to display the preset time and washing time remaining.Circuit consists of display circuit, pulse generator and timing circuits, alarm circuit and washing machine positive negative state control circuit. Display circuit is two units of digital pipe, use of catholic erection CD4511 pieces as digital tube decoding chips. Second pulse generator adopted widely used mature 555 timing, as the signal, the clock signal chip. Timing circuits using four decimal reversible counter 74ls192 chip design, respectively for the decimal system and six for pletion time of the circuit, timing, and timer function. Alarm circuit and status display circuit is simple logic crosscoupled nand gates and 74ls04 74ls00, consisting of logic circuit, control and lightemitting diodes, buzzer to realize alarm and status display. The motor control circuit used 38 74ls138 decoder crosscoupled nand gates and bination of circuit, motor and suspended state.Computer software simulation and experiment through physical test, has the good feasibility, a washing machine, used for the control circuit of the general requirement can meet.Keywords: washing machine control, Digital electronic control, The timer目錄 1 2 方案比較 2 設(shè)計要求分析與方案比較 2 方案論證 4 方案選擇 4 5 5 5 分秒計數(shù)器選擇 5 顯示電路 5 狀態(tài)顯示電路 6 洗衣機控制電路 6 報警電路及延時電路 6 7 秒信號發(fā)生器電路 7 分秒計數(shù)器 7 顯示電路 8 狀態(tài)顯示電路 8 洗衣機控制電路 9 報警電路 9 特殊器件介紹 10 555定時器 10 74LS192 計數(shù)器 11 CD4511譯碼器 13 74LS138譯碼器 13 各單元模塊的聯(lián)接 14 工作原理 14 總原理圖 15 元件清單 16 16 設(shè)計所用工具 16 設(shè)計流程 16 工作流程 17 18 系統(tǒng)功能 18 調(diào)試方法 18 調(diào)試內(nèi)容 18 預(yù)設(shè)時間輸入調(diào)試 18 指示燈調(diào)試 20 報警器調(diào)試 216．設(shè)計總結(jié) 22 23 23西華大學(xué)課程設(shè)計說明書 現(xiàn)代社會人們的生活水平越來越高，洗衣機作為一種方便人們洗滌的設(shè)備進入了千家萬戶。隨著大規(guī)模集成電
