為了有效地解決數(shù)據(jù)交換時(shí)數(shù)據(jù)表示的通用性問(wèn)題，使得數(shù)據(jù)在不同的業(yè)務(wù)系統(tǒng)間都能夠被識(shí)別，本課題采用調(diào)查研究和文獻(xiàn)研究相結(jié)合的方法，首先對(duì)淮北礦業(yè)集團(tuán)各業(yè)務(wù)系統(tǒng)數(shù)據(jù)庫(kù)中數(shù)據(jù)表進(jìn)行統(tǒng)計(jì)和分析，重點(diǎn)分析了需要轉(zhuǎn)換數(shù)據(jù)的類(lèi)型和邏輯關(guān)系，總結(jié)出其所有數(shù)據(jù)轉(zhuǎn)換的邏輯關(guān)系，然后參考現(xiàn)有文獻(xiàn)資料中提出的數(shù)據(jù)轉(zhuǎn)換模型，最后制定出有獨(dú)創(chuàng)性的數(shù)據(jù)源標(biāo)準(zhǔn)和數(shù)據(jù)映射標(biāo)準(zhǔn)。并采用通用的數(shù)據(jù)描述語(yǔ)言——XML(eXtensive Makeup Language)將其主要部分表示出來(lái)。該數(shù)據(jù)標(biāo)準(zhǔn)有著數(shù)據(jù)表示范圍超越數(shù)據(jù)表、數(shù)據(jù)轉(zhuǎn)換的靜態(tài)模型和動(dòng)態(tài)模型相結(jié)合、數(shù)據(jù)表示和實(shí)體數(shù)據(jù)庫(kù)相分離等特點(diǎn)。通過(guò)項(xiàng)目實(shí)踐，證明了該標(biāo)準(zhǔn)能夠解決數(shù)據(jù)表示的通用性問(wèn)題，能夠?qū)崿F(xiàn)了數(shù)據(jù)在不同業(yè)務(wù)系統(tǒng)之間識(shí)別與轉(zhuǎn)換。

　　Abstract:

　　In this paper a portable human-machine interface system based on the STM32 Micro-controller to be used in the compution of Total station measurement is designed. The methods of simulation bus timing by MCU IO port and use SPI interface Flash to storage the font is used. We stored the chinese font in the external SPI interface Flash and load them when we need to use them. The design of chinese font show system based on the latest ARM Cortex-M3 processor was finished. Human-machine interface system which has self definite chinese font is realized.
