摘 要
 本課題針對(duì)目前溫度檢測(cè)儀表的現(xiàn)狀及其存在的主要問(wèn)題，設(shè)計(jì)了一種32路溫度巡檢儀。該儀表可擴(kuò)展為0-99路，因此可以巡回檢測(cè)多個(gè)測(cè)試點(diǎn)的溫度，不僅具有精度高、功耗低等優(yōu)點(diǎn)，還可以及時(shí)報(bào)警、顯示、打印和采取保護(hù)措施，使用相當(dāng)方便。在硬件上，溫度檢測(cè)元件采用單總線方式下的先進(jìn)的數(shù)字式溫度傳感器，摒棄了傳統(tǒng)的A/D轉(zhuǎn)換器，電路結(jié)構(gòu)大為簡(jiǎn)化。除此之外，采用了實(shí)時(shí)時(shí)鐘電路、顯示驅(qū)動(dòng)電路、發(fā)光二極管報(bào)警電路、繼電器保護(hù)電路和集E2PROM看門狗up監(jiān)控于一體的集成芯片作為其主要的硬件結(jié)構(gòu)。在軟件上，用匯編語(yǔ)言對(duì)單片機(jī)編程以實(shí)現(xiàn)對(duì)各測(cè)試點(diǎn)溫度值的檢測(cè)和集中管理，并且通過(guò)軟件編程以極少量按鍵實(shí)現(xiàn)了對(duì)儀表的方便操作。另外，從軟硬件兩方面對(duì)系統(tǒng)進(jìn)行了抗干擾性的設(shè)計(jì)，從而使系統(tǒng)的可靠性得到明顯的提高，總之，該課題的研究將對(duì)一般環(huán)境下的溫度的巡回檢測(cè)提高到了一個(gè)新的水平，具有較高的社會(huì)推廣價(jià)值。

ABSTRACT
 In accordance with the present situation and mainly existing problems of the temperature instrument, a kind of 32-orad temperature-cruising test instrument has been designed in this article. The road's number of the meter can be broadened from No.0 to No.99. Besides its high precision, low power, it can alarm, display and register, which makes it easily controlled. On the hardware, the 1-wire progressive digital the mometer has been elected to test temperature so the traditional A/D converter will not be used. This makes the meter circuit easy. The circuit also include real-time clock circuit, analog series communication port control display driving circuit, LED alarm circuit and the circuit which center Watchdog, E2PROM, up supervisory on one chip. On the software, using assembly language in programming for CPU realized monitoring the temperature on every road and center management. In addition, there are only 4 buttons, but can control easily. Generally, the study on this topic will develop a high level of the common environmental temperature instruments measuring and management, and it is very worthy of generalization and application.
