【正文】 門禁讀卡器功能測試儀設計 I 基于 STM32 系列單片機的 門禁 讀卡器功能測試 儀設計 摘 要 本設計是基于 STM32 系列 的 單片機 進行的對 SXG 系列 門禁 讀卡器 的功能測試。在設計的同時對 STM32 單片機 的理論基礎和外圍擴展知識進行了比較全面準備。 對SXG 系列 門禁 讀卡器的功能測試 在硬件與軟件方面進行同步設計。硬件部分主要由STM32F107VCT6 微處理器 、 LED 顯示電路 、 JTAG 下載電路、電源轉換電路 、韋根通信電路、 以及電機控制電路等組成， 系統(tǒng)通過 LED 和米字型 LED 顯示測試結果，所以具有人性化的操作和直觀的顯示效果。 軟件方面主要包括 系統(tǒng)進入 停止模式和退出停止模式、韋根通信、控制電機 、鍵盤測試等。本系統(tǒng)以 C 語言進行軟件設計，為了便于擴展和更改， 軟件的設計采用模塊化結構，使程序設計的邏輯關系更加簡潔明了，以便更簡單地實現(xiàn) 對 SXG 系列 門禁 讀卡器的功能測試。所有程序編寫完成后，在 keil 軟件中進行調試 , 確定沒有問題后， 焊接硬件測試 SXG 系列 門禁 讀卡器。 關鍵詞 STM32F107VCT6 韋根通信 電機控制 門禁讀卡器功能測試儀設計 II THE DESIGN OF THE ACCESS CONTROL READER FUNCTION TESTER ABSTRACT Taking the SXG series of access control reader for research object ,this paper designed the function tests which based on the series of STM32 microcontrollers. The theoretical basis of the STM32 MCU and peripherals expand your knowledge in the design, while a more prehensive preparation. SXG series access functional test of the reader hardware and software aspects of the synchronous design. The hardware part is mainly microprocessors by STM32F107VCT6, LED display circuit, JTAG download circuit, the power conversion circuit, Wiegand munication circuit, and motor control circuit and other position, the system LEDsegment LED displays the test results, so humane operation and intuitive display. The software system enters stop mode and exit the stop mode, Wiegand munications, control, motors, keyboard testing. The system software design in C language, in order to facilitate the expansion and change, the software design is modular in structure, programming logic is more concise, in order to more easily achieve the functional testing SXG series access card reader. All programs after their pletion, in keil software for debugging, there is no problem, welding SXG series access card reader hardware testing.
