摘要
本論文采用臺(tái)灣凌陽(yáng)公司生產(chǎn)的’nSP系列16位SPCE061A單片機(jī)，設(shè)計(jì)了用于檢測(cè)爐窯溫度的溫度巡檢系統(tǒng), 該系統(tǒng)在冶金、化工等領(lǐng)域應(yīng)用較為廣泛。課題主要內(nèi)容包括硬件設(shè)計(jì)（熱電偶溫度傳感器、熱電偶溫度變送器、驅(qū)動(dòng)芯片、LED顯示器等）以及軟件程序設(shè)計(jì)（模擬量的采集、A/D轉(zhuǎn)換模塊、定時(shí)器、I/O模塊等）。
該系統(tǒng)可以在一個(gè)采樣周期內(nèi)實(shí)現(xiàn)四個(gè)溫度采集點(diǎn)的巡回檢測(cè)、各個(gè)采集點(diǎn)的溫度的LED顯示、溫度的超限報(bào)警功能。論文詳細(xì)闡述了軟件設(shè)計(jì)的思路，并對(duì)硬件接口電路和程序流程圖進(jìn)行了詳細(xì)的分析，并對(duì)系統(tǒng)的抗干擾性能進(jìn)行了優(yōu)化設(shè)置。
大部分程序采用了C語(yǔ)言編程，相較于匯編語(yǔ)言來(lái)說(shuō)它具有結(jié)構(gòu)靈活，數(shù)字信號(hào)處理能力強(qiáng)的特點(diǎn)，而且只要修改參數(shù)就可以方便地應(yīng)用于其它類(lèi)似的系統(tǒng)。

The Design of System for Itinerant Temperature Measurement Using MCU
Abstract
The author of the paper designs a itinerant measurement system of temperature in measuring the furnace temperature using the SPCE061A 16-bit MCU in the ’nSP series made by Taiwan Sunplus Ltd , which is used widely in the filed of metallurgical engineering and chemical industry. This paper contains the designs of hardware (the thermocouple sensor, the thermocouple convert, the driver, the LED displayer etc.) and the software (the analog data collect, the ADC convert unit, the Timer，the I/O unit etc.).
The system can measure the furnace temperature of the four points in a sample period, display the temperature data of each point on the LED displayer and give an alarm when the temperature oversteps the normal boundaries. The paper tells the designing thought in detail and analyses the circuit diagrams and charts with clarity.
Most of the programs are described by C language, which has the advantages of agility structure and strong Digital Signal Processing ability to the assemble language. The program can be transplanted conveniently to other similar system just by modifying the parameters.

Keywords: SPCE061A MCU, sample，analogy-digital-convert
