緒論 4 醫(yī)學(xué)處理,這就是說,需要在競(jìng)賽前若干天就進(jìn)行按摩。在具體操作上,必須根據(jù)運(yùn)動(dòng)項(xiàng)目的特點(diǎn),以及運(yùn)動(dòng)員的個(gè)體特點(diǎn)進(jìn)行。 根據(jù)地運(yùn)動(dòng)員在各項(xiàng)運(yùn)動(dòng)中比賽,對(duì)他們?cè)谂R場(chǎng)前后所出現(xiàn)的各種變化,我們采用按摩幫助他們克服賽前發(fā)生的一些機(jī)能失調(diào),消除賽后出現(xiàn)的疲勞,加速體能恢復(fù),以利再戰(zhàn),取得了一定的效果。如國(guó)內(nèi)的保健按摩、小兒保健按摩、運(yùn)動(dòng)按摩、美容按摩、減肥按摩、國(guó)外還有旅游按摩、情景按摩、寵物按摩等。記住人生最大的幸福就是 “家里無病人,牢中無親人 ”這句話,使自己堂堂正正做人,干干凈凈干事,平平安安退休,永遠(yuǎn)心身健康,遠(yuǎn)離醫(yī)院和監(jiān)獄。知足,使人心態(tài)平靜、安祥、達(dá)觀、超脫、常樂,心情舒暢,身體健康。一個(gè)有正氣的人,必然是一個(gè)嚴(yán)以律己、剛正不阿的人,他時(shí)刻都會(huì)表現(xiàn)出高潔、剛正、坦誠(chéng)的品質(zhì),不會(huì)與邪惡同流合污,不會(huì)進(jìn)監(jiān)獄。 “銳氣 ”即銳利的士氣,就是要有一股子勁和一種韌性,一種高昂的熱情和堅(jiān)忍不拔、不屈不撓的毅力。 “朝氣 ”即早晨的空氣,引伸為精神振作,積極向上 ,蓬勃進(jìn)取。因此,我們每個(gè)黨員干部一定要加強(qiáng)學(xué)習(xí),注重自身道德修養(yǎng),樹立正確的世界觀、人生觀、價(jià)值觀和從政道德觀,認(rèn)真辨別真與偽、善與惡、榮與辱等是非觀念,以高尚的道德情操,飽滿的熱情和健康的體魄干好每一項(xiàng)事業(yè),使自己心身健康,青春煥發(fā),延年益壽。美國(guó)耶魯大學(xué)、密西根大學(xué)的病理研究人員曾對(duì)數(shù)千人的健康狀 況進(jìn)行跟蹤調(diào)研,結(jié)果表明,善良正派、與他人融洽相處者預(yù)期壽命顯著增加,在男性中尤為明顯。遠(yuǎn)在春秋時(shí)代,孔子就提出了 “仁者壽的觀點(diǎn),并強(qiáng)調(diào): “大德必得其壽 ”。單片機(jī)具有優(yōu)異的性能價(jià)格比,控制功能強(qiáng)和低電壓、集成度高、體積小、可靠性高、低功耗等特點(diǎn),在工業(yè)控制、智能化儀器儀表、智能接口、家用電器、兒童玩具、健身器材等許多領(lǐng)域都得到了廣泛的應(yīng)用。為了滿足人們的需要和市場(chǎng)的需求,按摩機(jī)控制系統(tǒng)開發(fā)技術(shù)應(yīng)運(yùn)而生。 drive and control of LED 東華理工大學(xué)長(zhǎng)江學(xué)院畢業(yè)設(shè)計(jì)(論文) 目錄 III 目 錄 緒論 ...............................................................................................................................................

With techniques of SCM (Single Chip Microputer) and PWM of DC (Direct Current) motor, the design put forward the control system frame and the concrete design technique projects at first. Then elaborated the total realization of the control system from the hardware electric circuit. Next, bined the hardware to put forward the mind o f software design, and made use of Assembly language carrying out it. Finally, made use of the peripherals, such as the key, the buzzer,the neon lamp and the LED (Light Emitting Diode) figures tube, providing the service for the customer, and carry out the massage function and interaction for both the machine and the person. The customer can let massage machine work on the fortable method and vibration speeds by the key。 本設(shè)計(jì)是基于單片機(jī)的 PWM 傳動(dòng)控制電路,利用 MOSFET(金屬氧化半導(dǎo)體場(chǎng)效應(yīng)晶體管 )來實(shí)現(xiàn),綜合運(yùn)用了直流電機(jī)PWM 技術(shù)、交流檢測(cè)技術(shù)以及 LED 驅(qū)動(dòng)與控制技術(shù),實(shí)現(xiàn)了按摩機(jī)控制系統(tǒng) 可以按18 檔速度進(jìn)行按摩, 可提供 4 種獨(dú)特的按摩方式, 用戶可根據(jù)喜好利用按鍵調(diào)節(jié)速度檔次、按摩方式 等要求。本設(shè)計(jì)以單片機(jī)技術(shù)和直流電機(jī) PWM 調(diào)速技術(shù)為基礎(chǔ)提出了控制系統(tǒng)框架和具體設(shè)計(jì)技術(shù)方案,從硬件電路方面闡述了控制系統(tǒng)的總體實(shí)現(xiàn),利用蜂鳴器來告警或提示按摩完成;利用按鍵,蜂鳴器 ,氖燈, LED 數(shù)碼管等外圍設(shè)備為用戶提供服務(wù),實(shí)現(xiàn)人機(jī)交互和按摩功 能,并利用氖燈顯示當(dāng)前的工作狀態(tài);利用 LED 數(shù)碼管顯 示電機(jī)當(dāng)前的轉(zhuǎn)速。 交流檢測(cè)技術(shù) 。 And use the LED figures tube to manifestation present speed of motor.
