【正文】 nance imaging (MRI) suggests that certain areas of the brain may be involved. Several of the brain areas being researched are known to control emotion and the expression of emotion. These areas include the temporal lobe (large lobe of each side of the brain that contains a sensory area associated with hearing), the limbic system, the cerebellum, the frontal lobe, the amygdala, and the brain stem, which regulates homeostasis (body temperature and heart rate). Recent research has focused particularly on the temporal lobe because of the finding that previously healthy people who sustain temporal lobe damage 自動售貨機控制系統(tǒng)的設(shè)計與仿真 30 may develop autisticlike symptoms. In animal research, when the temporal lobe is damaged, social behavior declines, and restless, repetitive motor behaviors are mon. When measured by MRI, total brain volume appears to be greater for those with autistic disorders. Other neurological factors include lesions to the brain, congenital rubella, undiagnosed and untreated phenylketonuria (PKU), tuberous sclerosis, and Rett39。 自動售貨機控制系統(tǒng)的設(shè)計與仿真 27 5 總結(jié) 隨著計算機技術(shù)和通信技術(shù)的發(fā)展，自動售貨機的發(fā)展方向也必將向著 更加智能化和人性化的礎(chǔ)上，從顧客的實際需要出發(fā)，本文在分析了自動售貨機的特點后，完成了自動售貨機控制系統(tǒng)的設(shè)計，在設(shè)計的過程中，主要完成了以下幾個方面的工作； （ 1） 對自動售貨機的發(fā)展技術(shù)進行了總結(jié)和歸納，經(jīng)過總結(jié)可以發(fā)現(xiàn)節(jié)能環(huán)保是現(xiàn)在起發(fā)展的一個重要方向，同時，移動商務(wù)也是其發(fā)展的一個目標方向。 由 QuqrtusⅡ軟件內(nèi)部生成的 RTL 電路圖如圖所示： 自動售貨機控制系統(tǒng)的設(shè)計與仿真 22 仿真測試 對鎖定模塊進行仿真測試，得到如圖所示波形： 對該波形圖進行分析：在 5ns 前，系統(tǒng)復位；在 20ns 時，系統(tǒng)接收到確認取消模塊發(fā)出的 cancel 控制信號，此時該模塊會 立即產(chǎn)生 lock_out_entry 信號，即按鍵鎖定信號；在 40ns 時，系統(tǒng)操作結(jié)束，發(fā)出清零信號。 取消購買操作； 對系統(tǒng)執(zhí)行取消購買操作，得到如圖所示的仿真波形圖： 對該波形圖進行分析可以看出：在 5ns 前，系統(tǒng)處于復位狀態(tài)；在 10ns 的時候，系統(tǒng)接收到其他模塊發(fā)出的投幣信號，分別投入了一張 5 元貨幣和一張 10 元貨幣，同時，接收到別的模塊發(fā)出的信號 sum。 總額加和模塊： 不斷的更新并計算售貨機收到的總貨幣數(shù)量。 ? 輸出端口： led_buy,確認購買指示燈； led_cancel,取消購買指示燈； en_deliver,出貨信號； led1,投入貨幣總數(shù)的個位數(shù)（單位是元）； led10,投入貨幣總數(shù)的十位數(shù)（單位是元）。 QuartusⅡ支持多種輸入方式，例如原理圖輸入，硬件編程語言輸入等，在使用 QuartusⅡ軟件時，它會將設(shè)計人員設(shè)計好的硬件編程語言或者原理圖等自動轉(zhuǎn)換目標文件，最后將目標文件下載到器件中。 ? 上世紀 90 年代， CAD、 CAE 等技術(shù)已經(jīng)被廣泛應(yīng)用在電子領(lǐng)域方面。除此之外還有青島澳柯瑪自動商用設(shè)備有限公司、天津奧萊特自動售貨機有限公司等公司生產(chǎn)的自動售貨機也是比較常見的。 自動售貨機的優(yōu)點之一就是無需人工看守 ，這點在當今世界人工勞動力成本普遍急劇上升的年代成為了各商家最看重的一點，它可以 24小時不斷的進行自動售貨操作，在為商家降低成本的同時大大的增加了收益。自動售貨機作為自動化設(shè)備中的最常見的設(shè)備之一，由于其眾多的優(yōu)點，已經(jīng)在世界各地得到了普遍的發(fā)展并且還在不斷地發(fā)展。從這些數(shù)據(jù)可以看出自動售貨機所涉及的行業(yè)在零售行業(yè)中占據(jù)著不可替代的重要作用。自動售貨機從一開始的功能單一 結(jié)構(gòu)單一發(fā)展到現(xiàn)在的功能多元化個性化，該行業(yè)也成為信息化的一種表現(xiàn)?？删幊踢壿嬈骷涂删幊陶Z言的發(fā)展改變了傳統(tǒng)的電子設(shè)計的設(shè)計方法和 設(shè)計理念，同時也讓 EDA 技術(shù)有了更快的發(fā)展。 QuartusⅡ軟件有以下特點： 自動售貨機控制系統(tǒng)的設(shè)計與仿真 7 ? 支持多平臺的設(shè)計輸入，結(jié)合其處理和驗證功能使其成為一個全集化的開發(fā)平臺，讓開發(fā)周期變短。 當系統(tǒng)接收到相關(guān)信號輸入時，系統(tǒng)開始工作。 整個自動售貨機的內(nèi)部工作過程的總體框圖如圖所示： 對每一個子模塊進行 VHDL 設(shè)計，然后對其進行編譯，再編譯沒有錯誤后，通過編寫TestBeach 文件來 對其進行仿真測試來驗證每一個模塊的功能是否正確。 ? 輸出端口： sum_1,表示發(fā)出 1元貨幣的信號； sum_5,發(fā)出 5元貨幣的信號； sum_10,發(fā)出 10 元貨幣的信號； sum,投入貨幣總和信號； 電路原理圖如圖所示： 自動售貨機控制系統(tǒng)的設(shè)計與仿真 17 當系統(tǒng)輸入不同的投幣信號時，則 sum1,sum5,sum10 就會記錄相對應(yīng)的貨幣的數(shù)量，而 sum 則記錄了投入貨幣的總額。 顯示模塊會實時顯示售貨機收到的貨幣總額，并且通過 led1 來顯示投入貨幣的個位數(shù)， led2 來顯示投入貨幣的十位數(shù) 。最后在頂層文件中將各個子模塊進行例化并對子模塊進行了調(diào)用，并且對整個控制系統(tǒng)的仿真，經(jīng)過仿真測試的結(jié)果可以看出，整個控制系統(tǒng)的設(shè)計達到了最初的所有設(shè)計要求，完成了各項功能。s games measures in (7576 cm) in circumference, and a women39。 自動售貨機控制系統(tǒng)的設(shè)計與仿真 29 請刪除以下內(nèi)容， O(∩ _∩ )O 謝謝?。?！ The term autism refers to a cluster of conditions appearing early in childhood. All involve severe impairments in social interaction, munication, imaginative abilities, and rigid, repetitive behaviors. To be considered an autistic disorder, some of these impairments must be manifest before the age of three. The reference book used by mental health professionals to diagnose mental disorders is the Diagnostic and Statistical Manual of Mental Disorders , also known as the DSM. The 2021 edition of this reference book (the Fourth Edition Text Revision known as DSMIVTR ) places autism in a category called pervasive developmental disorders . All of these disorders are characterized by ongoing problems with mutual social interaction and munication, or the presence of strange, repetitive behaviors,interests, and activities. People diagnosed with these disorders are affected in many ways for their entire lives. Description Each child diagnosed with an autistic disorder differs from every other, and so general descriptions of autistic behavior and characteristics do not apply equally to every child. Still, the mon impairments in social interaction, munication and imagination, and rigid, repetitive behaviors make it possible to recognize children with these disorders, as they differ markedly from healthy children in many ways. Many parents of autistic children sense that something is not quite right even when their children are infants. The infants may have feeding problems, dislike being changed or bathed, or fuss over any change in routine. They may hold their bodies rigid, making it difficult for parents to cuddle them. Or, they may fail to anticipate being lifted, lying passively while the parent reaches for them, rather than holding their arms up in return. Most parents of autistic children bee aware of the strangeness of these and other behaviors only gradually. Impairments in social interaction are usually among the earliest symptoms to develop. The most mon social impairment is a kind of indifference to other people, or aloofness, even towards parents and close caregivers. The baby may fail to respond to his or her name being called and may show very little facial expression unless extremely angry, upset, or happy. Babies with autism may resist being touched, and appear to be lost in their own world, far from human interaction. Between seven and 10 months of age, most infants often resist being separated from a parent or wellknown caregiver, but these infants may show no disturbance when picked up by a stranger. Other children with autism may be very passive, although less resistant to efforts by others to interact. However, they do no
