【正文】 s. The single chip puter speed processing speed and enhanced peripheral equipment collection makes them suitable for the high speed event applications. However, these key applications also require these MCS highly reliable. Robust test environment and used to validate these both in ponent level or system level chip suitable tool environment to ensure the high reliability and low market risk. Intel platform engineering department in the development of an object oriented is used to verify its AT89C51 car SCM multi linear test environment. This goal is not 西昌學(xué)院畢業(yè)論文（設(shè)計） only to provide a robust AT89C51 automobile SCM test environment, and develop a can be easily extended and repeated used to validate several other future chip. Development of the environment AT89C51 connection. This paper discusses the test environment design and principle, it and all kinds of hardware, software environment ponent interaction, and how to use AT89C51. INTRODUCTION 8 AT89C51CHMOS process MCU is designed for processing high speed calculation and fast input / output. MCS51 MCU typical application is high speed event control system. Commercial application of motor control system, includes a modem, printer, copy machine, airconditioning control system, a disk drive and medical equipment. Automobile industry based on MCS51 single chip microputer control system of engine, suspension and antilock brake system. AT89C51 is particularly well applicable to profit from its processing speed and enhanced onchip peripheral functions, such as: vehicle dynamic control, dynamic vehicle suspension, antilock brake and stability control application. As a result of these critical applications, the market needs a reliable with low interference potential response of the cost effectiveness controller, service time and event driven in realtime applications that require integrated peripheral capacity in a single package, has higher average power in the central processor. Operating with unpredictable equipment economic and legal risk is high. Once enter the market, especially the mission critical applications such as in the autopilot or antilock brake system, the error will be prohibited by the financial. The redesign of the costs can be as high as 500K dollars, if the product family to enjoy the same core or peripheral design flaws, costs will be higher. In addition, replacement parts field is extremely expensive, because the equipment is used to put the module typically welded into an overall value than each ponent high several times. To mitigate these problems, in the worst environment and voltage conditions on the SCM in ponent level or system level testing is required. The Intel Chandler Platform Engineering Group offers a variety of singlechip processor and system validation. The system of authentication processing can be broken down into three 西昌學(xué)院畢業(yè)論文（設(shè)計） main sections. System type and application demand decided to apparatus to perform a test type. AT89C51provided with the following standard function: 4K bytes FLASH flash memory,128 MB internal RAM,32I/O line,2of 16timer / counter, a5vec。 Configuration software configuration work Along with the industrial automation level rise quickly, the wide application of puter in the industrial fields of industrial automation, the people of the increasingly high demand, a wide variety of control devices and process monitoring devices used in the fields of industry, the traditional industrial control software has been unable to meet the various needs of users. In the development of the traditional industrial control software, when industrial controlled object once the change, must modify the control system of the source, resulting in its long development cycle。每個字節(jié)寫入周期是自身定時的，通常約為 。激活相應(yīng)的 控制信號。推出掉電模式的唯一方法是硬件復(fù)位，復(fù)位后將重新定義全部特殊功能寄存器但不改變 RAM 中的內(nèi)容，在 Vcc 恢復(fù)到正常工作電平前，復(fù)位應(yīng)無效，且必須保持一定時間以使振蕩器重啟動并穩(wěn)定工作。同時， AT89C51 降至 0Hz 的靜態(tài)邏輯操作，并支持兩種可選的節(jié)電工作模式。 Intel Chandler 平臺工程組提供了各種單片機(jī)和處理器的系統(tǒng)驗(yàn)證。一旦進(jìn)入市場，尤 其任務(wù)決定性應(yīng)用諸如自動駕駛儀或反鎖制動系統(tǒng)，錯誤將是財力上所禁止的。汽車工業(yè)把 MCS51 單片機(jī)用于發(fā)動機(jī)控制系統(tǒng)，懸掛系統(tǒng)和反鎖制動系統(tǒng)。本文討論了這種測試環(huán)境的設(shè)計和原理，它的和各種硬件、軟件環(huán)境部件的交互性，以及如何使用 AT89C51。健壯的測試環(huán)境和用于驗(yàn)證這些無論在元部件層次還是系統(tǒng)級別的單片機(jī)的合適的工具環(huán)境保證了高可靠性和低市場風(fēng)險。 因?yàn)槊看蝹鬏?2 個字節(jié)， 8 位二進(jìn)制數(shù)值，所以一次串口能夠傳輸最大 255的數(shù)據(jù)，因?yàn)?ADC0809 是 8 位二進(jìn)制，最大值也是 255，所以將采集到的數(shù)據(jù)直接傳輸，在組態(tài)軟件中設(shè)置返回字 節(jié)為 6，沒字節(jié)為 8位，最大值 255，然后設(shè)置 6 個數(shù)據(jù)變量，每個變量對應(yīng)一個單元號，這個單元號就是代表通過串口傳進(jìn)組態(tài)的一個數(shù)據(jù)。 姓名： 年 月 日 西昌學(xué)院畢業(yè)論文（設(shè)計） 翻 譯 資 料 組態(tài)網(wǎng) 隨著工業(yè)自動化水平的迅速提高， 計算機(jī)在工業(yè)領(lǐng)域的廣泛應(yīng)用，人們對工業(yè)自動化的要求越來越高，種類繁多的控制設(shè)備和過程監(jiān)控裝置在工業(yè)領(lǐng)域的應(yīng)用，使得傳統(tǒng)的工業(yè)控制軟件已無法滿足用戶的各種需求。如今，伴隨著此設(shè)計的完成，復(fù)雜的心情煙消云散，自己甚至還有一點(diǎn)成就感。 西昌學(xué)院畢業(yè)論文（設(shè)計） 34 參考文獻(xiàn) [1]徐科軍 .傳感器與檢測技術(shù) [M].北京：電子工業(yè)出版社， [2]徐新民 .單片機(jī)原理與應(yīng)用 [M].浙江：浙江大學(xué)出版社， [3]薛曉書 .單片微機(jī)原理及接口技術(shù) [M].西安： 西安石油大學(xué) 出版社， [4]譚博學(xué)，苗匯靜 .集成電路原理與應(yīng)用 [M].北京：電子工業(yè)出版社， 2021 [5]劉蕓 .電路與電子技術(shù)基礎(chǔ) [M].北京：高等教育出版社， [6]姚福安 .電子電路設(shè)計與實(shí)踐 [M].濟(jì)南：山東科技技術(shù)出版社， 2021 [7]施智雄，胡放鳴 .實(shí)用模 擬電子技術(shù) [M].成都：電子科技大學(xué)出版社 , [8]譚浩強(qiáng) .C程序設(shè)計 [M].北京：清華大學(xué)出版社， 2021 [9]鄭君里， 楊為理 .信號與系統(tǒng) [M].北京：高等教育出版社， [10]張毅剛 ,彭喜元 .MCS51 單片機(jī)應(yīng)用設(shè)計 [M].哈爾濱： 哈爾濱工業(yè)大學(xué)出版社 ,2021 [11]戴佳 .51單片機(jī) C語言應(yīng)用程序設(shè)計實(shí)例精進(jìn) [M].電子工業(yè)出版社， 2021 [12]羅苑棠 .單片機(jī) 系統(tǒng)開發(fā)實(shí)例精講 [M].電子工業(yè)出版社， 2021 [13]王瑟 ,劉超．基于無線傳感器網(wǎng)絡(luò)應(yīng)用開發(fā) [J].微計算機(jī)信息， 2021,3133 [14]楊寧 .單片機(jī)與控制技術(shù) [M].北京：北京航天航空大學(xué)出版社， [15]張磊 .基于 C語言的單片機(jī)串行通信設(shè)計 [M].電子工業(yè)出版社 ,2021 西昌學(xué)院畢業(yè)論文（設(shè)計） 35 致 謝 詞 本論文是 從選題到完成，每一步都是在指導(dǎo)老師 蔣春蕾 悉心的指導(dǎo)下完成的，傾注了指導(dǎo)老師大量的心血。這樣本設(shè)計會更全面，實(shí)用性更強(qiáng)。該系統(tǒng)主要包括無線發(fā)射模塊、無線接收模塊、顯示模塊、組態(tài)網(wǎng)。 圖 29 發(fā)射模塊 西昌學(xué)院畢業(yè)論文（設(shè)計） 32 圖 30 接收模塊 組態(tài)網(wǎng) 的測試與運(yùn)行 在 組態(tài)網(wǎng) 上也將實(shí)時顯示環(huán)境溫度 數(shù)據(jù)。 ? 裝上單片機(jī)，再測量其電壓輸入口 40 引腳 VCC 電壓（ 5V）、 31 引腳 EA/VPP 引腳電壓（ 5V）和晶振兩引腳與地之間的電壓（一般為 ）。 ? 線路檢測：根據(jù)電路圖用萬用表檢測 PCB 板線路是否有短路和斷路現(xiàn)象。電路板制作可采用腐蝕和雕刻，采用雕刻的方法制作電路板比較方便，雕刻的電路板上的路線完整性較好；腐蝕電路板時間快但腐蝕出來的線路存在沙眼。 在布線的過程中，線寬是一個重要的
