【正文】 o the condition with a number of thermal , this paper introduces the background and significance of the research, and analyzes the research status of the temperature measurement technology and the PSoC programmable system on hardware which uses the programmable system on chipCY8C5868AXILP032 as the core of the system designs of the entire circuit are four subsystems, including temperature acquisition module,amplifier module, A/D converter module, munication the Pt1000 platinum resistance using threewire connection as temperature signal input uses a unique bridge circuit as measurement technology which has its advantages in antijamming capability, the impact of lead resistance, the bridge and measuring circuit isolated voltage from the bridge circuit is amplified and converted into digital signal, then acquire corresponding temperature through the processor, and introduce the principle and function of each subsystem in the design of hardware to system requirements, ΔΣADC is configured the relevant parameters, such as resolution, sampling the basis of the system hardware design platform, using PSoC integrated software development environment for the design of the system, including the temperature signal acquisition, AD value and temperature value, temperature pensation, Modbus munication protocol and message frame is mainly aimed at the actual temperature acquisition, temperature error pensation, the main method of which bines the piecewise and linear scale meet the munication with the puter, the munication protocol based on Modbus is joined in PSoC, adapting RS485 interface standards to plete the sending and receiving data between the two, and configuring each parameter of UART of fullduplex munication inside the PSoC, using CRC cyclic redundancy , the system is tested to check the operation of the , using the special download tools, PSoC MiniProg to debug the download programming interfaces, visual basic is for munication test, then the resistance box simulate platinum resistance temperature , summarizing the work of this paper, at the same time, the further prospects are : Temperature measure。設(shè)計中主要針對的是實際溫度值獲取、溫度誤差補償?shù)脑O(shè)計,其中采用的主要方法是分段線性化和線性標度變換相結(jié)合的方法。選取鉑電阻Pt1000作為溫度傳感器,鉑電阻采用三線制接法。本文設(shè)計了一種以Pt1000作為溫度傳感器,以可編程片上系統(tǒng)PSoC作為核心芯片,采用片內(nèi)的模擬和數(shù)字IP核資源,利用Modbus協(xié)議進行上位機通信的溫度測量系統(tǒng)。溫度的測量直接關(guān)系到產(chǎn)品的質(zhì)量、生產(chǎn)效率以及生產(chǎn)安全等重大技術(shù)指標。以上所述只是撰寫英文摘要時應(yīng)注意的問題中的一小部分,尚有許多問題,需要進一步探討。例如,英文中有不少動詞,do,run,get,take等,雖簡單常用,但其意義少則十幾個,多則幾十個,用這類詞來描述研究過程,讀者難免產(chǎn)生誤解,甚至會不知所云,這就要求根據(jù)具體情況,選擇意義相對明確的詞,諸如perform,achieve等,以便于讀者理解。但在某些情況下,特別是表達作者或有關(guān)專家的觀點時,又常用主動語態(tài),其優(yōu)點是鮮明有力。2)在采用一般過去時敘述研究過程當中提及在此過程之前發(fā)生的事,宜采用過去完成時。選擇適當?shù)臅r態(tài)和語態(tài),是使摘要符合英文語法修辭規(guī)則的前提。第二,對屬于“四部分”的內(nèi)容,也應(yīng)適當取舍,做到簡明扼要,不能包羅萬象。英文摘要的內(nèi)容要求與中文摘要一樣,包括目的、方法、結(jié)果和結(jié)論四部分。(7)The results agree with...。(3)This paper concludes that...。(9)The method was based on...。(5)The experimental results are obtained by...。(19)Based on...is described discussed presented analyzed dealt with in this paper(20)In this paper...is discussed explored an analyzed , 通常處于摘要正文的中間 , 多描述研究的方法、手段、過程、步驟或結(jié)果拓展句常見句型或表達方法如下(1)The method of...was used to...。(15)This paper is to...。(11)The purpose of the present study is was to...。(7)The use of...is addressed。(3)The pr
