PCI ExpressTM is the third generation of PCI (PeripheralComponent Interconnect) technology used to connect I/Operhipheral devices in computer systems. It is intended asa general purpose I/O device interconnect that meets theneeds of a wide variety of Computing platforms such asdesktop, mobile, server and communications. It alsospecifies the electrical and mechanical attributes of thebackplane, connectors and removable cards in thesesystems.
Many telecommunications and Computing applicationsneed high effi ciency step-down DC/DC converters thatcan operate from a very low input voltage. The highoutput power synchronous controller LT3740 is idealfor these applications, converting input supplies rangingfrom 2.2V to 22V to outputs as low as 0.8V with loadcurrents from 2A to 20A. Applications include distributedpower systems, point-of-load regulation and conversionof logic supplies.
為了提高傳統(tǒng)溫度控制系統(tǒng)的性能，將PID控制理論與嵌入式系統(tǒng)相結(jié)合，采用瑞薩電子公司的H8S/2166作為核心處理器，AD公司的AD7705以及熱敏電阻溫度傳感器作為溫度檢測(cè)單元，利用4×6小鍵盤(pán)、LCD顯示器和S1D13305液晶控制器達(dá)到良好的人機(jī)交互，設(shè)計(jì)出了一個(gè)應(yīng)用于化工領(lǐng)域的嵌入式實(shí)時(shí)溫度控制系統(tǒng)。相比于傳統(tǒng)溫度控制系統(tǒng)，該系統(tǒng)提供了更強(qiáng)的計(jì)算能力和可擴(kuò)展能力，采用增量PID控制算法實(shí)現(xiàn)復(fù)雜控制。通過(guò)實(shí)驗(yàn)，該系統(tǒng)能達(dá)到0.1 ℃的溫度控制精度以及小于120 s的溫度穩(wěn)定時(shí)間。
Abstract:
In order to improve the performance of conventional temperature control system， combining PID control theory with embedded systems， using the Renesas Electronics Corp. H8S/2166 micro-controller as a core processors， AD7705 and thermistor temperature sensor as a temperature detection unit and 4×6 small keyboard， LCD and S1D13305 LCD controller as a good human-computer interaction， this paper designed an embedded real-time temperature control system which is applied in chemical industry. Compared with conventional temperature control system， this system provides more Computing power and extensibility， and adopts PID control algorithm for complex control. Through the experiment， the system can reach temperature control accuracy of 0.1 ℃ and temperature stabilization time of less than 120 seconds.
雖然PIC都是8位的單片機(jī)，但都采用RISC（Reduced Instruction Set Computing）核心結(jié)構(gòu)，這有別于過(guò)去一般的CISC(Complex Instruction Set Computing)結(jié)構(gòu)。所謂RISC結(jié)構(gòu)就是采用哈佛雙總線結(jié)構(gòu)，將地址總線與數(shù)據(jù)總線分開(kāi)，因此在同一個(gè)指令執(zhí)行過(guò)程中，數(shù)據(jù)與地址可以同時(shí)傳送，避免了總線處理上的瓶頸。
