【正文】 xt to the limit. In setting process, according to different projects such as the trigger way into four separate tasks table. Set in accordance with the demand after the pletion of all the tasks set to plete the project, 4 pm can be viewed and revised table has been set for the various items, and to generate a list of items to the total. 3 Download task project through USB RIGOL DM3000 Digital Multimeter to the highend PC, Click the Download button, above steps will develop a good list of tasks to download highend RIGOL DM3000 Digital Multimeter preserved, Click the Start button after the mission. (The first link, if RIGOL DM3000 highend digital multimeter to spare the state, PC will automatically synchronized RIGOL DM3000 highend Digital Multimeter the RTC time, time to prevent two different errors. RIGOL task DM3000 preserved in the highend digital multimeter, If it is not necessary for the implementation of the current PC operating or displaying data collection can be disconnected, RIGOL DM3000 of highend digital multimeter the operation will not have an impact. 4 return data and display the highend RIGOL DM3000 digital multimeter developed in accordance with the mandate to collect measurements, PC through the USB or LAN read measurement values, the preservation of the PC, Meanwhile RIGOL DM3000 highend digital multimeter of Flash can keep measurements, But its storage space for the PC is much smaller. Figure 2 shows the windowPC to read data saved to the database, the database established in the works automatically established, It is not additional to development of the database. For reading back the data provided in the form of software and image shows two models, if the state surveillance software, forms and images automatically updated. There will be a report of the show and the voice of the Alarm.Aggregate Currently, base stations by the general board serial port expansion box warning linking achieve environmental monitoring, RIGOL DM3000 using highend digital multimeter Base Station Power and the environment focus on monitoring, to remove the specialized equipment to the internal monitoring board, there is a change in equipment or upgrading, Customization is no need to remonitoring hardware, software only needs to revise the allocation will be, So not only improves the working efficiency more cost savings.Above to the base station signal monitoring example, briefed Patrol functions in monitoring the application. RIGOL DM3000 highend digital multimeter scope of application is very extensive, As long as the machines provide 20 measurements within the scope of the measurement functions, regardless of multichannel or single channel. Whether or regular measurement cycle measurement can be materialized. 附錄3include include define ad_con P2define addata P0define Disdata P1define uchar unsigned chardefine uint unsigned intsbit ALE=P2^3。sbit START=P2^4。sbit OE=P2^5。sbit EOC=P3^7。sbit DISX=Disdata^7。sbit MODE=P3^5。sbit TON=P3^6。uchar code dis_7[11]={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90,0xff}。uchar code scan_con[4]={0xfe,0xfd,0xfb,0xf7}。uchar data ad_data[8]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}。uint data dis[5]={0x00,0x00,0x00,0x00,0x00}。delay1ms(uint t){ uint i,j。 for(i=0。it。i++) for(j=0。j120。j++)。}scan(){ uchar k,n。 uint h。 dis[3]=0x00。 for(n=0。n8。n++) { dis[2]=ad_data[n]/51。 dis[4]=ad_data[n]%51。 dis[4]=dis[4]*10。 dis[1]=dis[4]/51。 dis[4]=dis[4]%51。 dis[4]=dis[4]*10。 dis[0]=dis[4]/51。 for(h=0。h150。h++) { for(k=0。k4。k++) { Disdata=dis_7[dis[k]]。 if(k==2){DISX=0。} P3=scan_con[k]。delay1ms(1)。P3=0xff。 } } dis[3]++。 if(MODE==0) {delay1ms(100)。key_scan()。} }}key_scan(){ int o=0。 int k。 dis[3]=0x00。 while(o8){ dis[2]=ad_data[o]/51。 dis[4]=ad_data[o]%51。 dis[4]=dis[4]*10。 dis[1]=dis[4]/51。 dis[4]=dis[4]%51。 dis[4]=dis[4]*10。 dis[0]=dis[4]/51。 for(k=0。k4。k++) { Disdata=dis_7[dis[k]]。 if(k==2){DISX=0。} P3=scan_con[k]。delay1ms(1)。P3=0xff。 } if(TON==0) {delay1ms(400)。o++。dis[3]=o。} if(MODE==1) {delay1ms(100)。scan()。} } }test(){ uchar m。 uchar s=0x00。 ad_con=s。 for(m=0。m8。m++) { ALE=1。_nop_()。_nop_()。ALE=0。 START=1。_nop_()。_nop_()。START=0。 _nop_()。_nop_()。_nop_()。_nop_()。 while(EOC==0)。 OE=1。ad_data[m]=addata。OE=0。s++。ad_con=s。 } ad_con=0x00。}main(){ P0=0xff。 P2=0x00。 P1=0xff。 P3=0xff。 while(MODE==1) { test()。 scan()。 } }附錄4附錄5致　　謝在我寫本論文的過程中，胡玲燕老師給我提供了許多資料，并對實踐中出現(xiàn)的問題給予耐心的解答，完稿之后在百忙之中仔細閱讀，給出修改意見。有時午夜向胡老師求助，她從不推辭，認真解答。胡老師愛崗敬業(yè)，治學嚴謹，思維嚴密，平易近人是我十分尊敬的老師，在此對她表示感謝。在本文錄入的過程中，得到了楊通同學的幫助，在這里對他也表示由衷的感謝！連大學學位論文版權(quán)使用授權(quán)書本學位論文作者及指導教師完全了解“大連大學學士論文版權(quán)使用規(guī)定”，同意大連大學保留并向國家有關(guān)部門或機構(gòu)送交學位論文的復印件和電子版，允許論文被查閱和借閱。本人授權(quán)大連大學可以將本學位論文的全部或部分內(nèi)容編入有關(guān)數(shù)據(jù)庫進行檢索，也可采用影印、縮印或掃描等復制手段保存和匯編學位論文。 作者簽名： 導師簽名： 年 月 日 45
