Device and software are included. Device acts as a unit for a generator set and software provides friendly interface to monitor and control assistant devices. Device is distributed designed and made up of microprocessor and periphery electrocircuits. Motorola HC12 MCU acts as Core and analog measure module, switch status monitor module, relay control module, LCD display module and munication module are included in periphery electrocircuits. Software is developed by Visual Basic and database is developed by SQL Server . With the software, device can operate with the procedure step by step which is solidified by munication between PC and device. USB and RS232 munication interfaces are available in device which makes munication easy. The puter supervisory amp。 關鍵 監(jiān)控系統(tǒng)，模塊化設計，嵌入式系統(tǒng) 攀枝花學院專科畢業(yè)設計（論文） ABSTRACT II ABSTRACT This paper analyzes the development of the puter supervisory amp。上位機嵌入式系統(tǒng)可視化編程軟件采用面向?qū)ο蟮木幊陶Z言 Visual Basic 結(jié)合大型商用數(shù)據(jù)庫 SQLServer 開發(fā)，同時利用軟 /硬件協(xié)同設計的方法，使煩瑣復雜的針對硬件的控制編程變得簡單、直觀，實現(xiàn)在線過程編程，然后通過 RS232 通訊接口或者 USB 通訊接口將控制程序下載到下位機裝置的FLASH 頁中，下位機裝置則按照下發(fā)的程序流程執(zhí)行相應的測量、檢測和控制功能，可重復擦寫的 FLASH 中下載程序的內(nèi)容和順序的不同使得同一個裝置可以實現(xiàn)不同的功能，達到下位機裝 置的一機多用。系統(tǒng)由下位機監(jiān)控裝置和上位 PC 機嵌入式系統(tǒng)可視化編程軟件構(gòu)成。 攀枝花學院畢業(yè)設計
